In long term evolution (LTE) system, interferometry resource (IMR) is had been introduced into allow be configurable for user Interference measurement on the predetermined resource of equipment (UE).IMR in LTE system is typically based on periodical zero energy channel state information Reference signal (ZP CSI-RS).

IMR allows UE to capture interference characteristic.In (NR) system of in the 5th generation (5G) or newly eating dishes without rice or wine, ZP CSI-RS can be with The mode similar with LTE system is used as the IMR of UE, in particular for inter-cell interference measurement.It can be easily by being assigned (no transmission) is transmitted for the zero energy on the resource element (RE) for interference measurement to support.As a result, UE can utilize corresponding RE The inter-cell interference transmitted come the Physical Downlink Shared Channel (PDSCH) estimated corresponding to adjacent transmission receiving point (TRP).It should Mode is considered as suitable for conventional inter-cell interference measurement, and leads to relatively low expense.

It should be noted, however, that in the scene for the 5G or NR system for supporting multi-user's multiple-input and multiple-output (MU-MIMO) operation In, this periodicity ZP CSI-RS transmission can be low efficiency for intra-cell interference measurement.For example, due to MU-MIMO's The intra-cell interference measurement of dynamic dispatching decision, CSI can be dynamic.A ZP CSI-RS is measured for being based on resource On interference UE for, some other UE for not answering the data of the request of interference measurement to transmit can answer the request of scheduled transmission Send data.This can lead to the interference not being reflected in the result of interference measurement.In this case, based on being semi-statically configured The interference measurement of periodical ZP CSI-RS be not enough to accurately estimate the intra-cell interference from different UE.Thus, accordingly CSI report possibly can not reflect real channel condition, this deteriorates the performance of link adaptation.

The feasible pattern of interference measurement is to utilize the dedicated non-zero power CSI-RS of UE in cell in the scene of MU-MIMO (NZP CSI-RS) is used as IMR, and wherein TRP can estimate the interference of the UE dispatched jointly come on self-corresponding NZP CSI-RS. That is, being interfered caused by the combination of the available UE matched as any CSI-RS transmission with Wave beam forming of TRP.

The two ways for intra-cell interference measurement by using the dedicated NZP CSI-RS of UE may be present.

First way, which is UE, obtains CSI from the TRP of service based on disposable CSI-RS transmission.It is assumed that the UE of all scheduling NZP CSI-RS compete with each other.The dedicated NZP CSI-RS of the UE of transmission is used for both channel and interference measurement.That is, UE executes letter Road estimation and the estimation of received desired signal then is subtracted to complete in cell and inter-cell interference from the entire signal that receives Measurement.As pairs of UE NZP CSI-RS on every other pairs of UE caused by interference be considered as intra-cell interference.One As for, result that the measurement of intra-cell interference based on disposable CSI-RS transmission needs to be estimated according to link level it is highly denser The NZP CSI-RS of degree.

Another way base in order to keep low CSI-RS density, for using the intra-cell interference of NZP CSI-RS to measure In the channel estimation and interference simulation of the NZP CSI-RS using other UE.In this approach, aggrieved UE can be used to be sent to and invade Enter UE_iNZP CSI-RS estimation by from intrusion UE_iThe characteristic of channel of aggrieved UE of interference (be expressed as H_i).Then by Evil UE can be from intrusion UE_iObtaining is R_i=H_i*H_i ^HIntra-cell interference, wherein ()^HFor transposition conjugate operation.Herein, aggrieved UE can refer to the UE by the interference from intrusion UE, and invade UE and can refer to the interference that can lead to the channel to aggrieved UE Those UE.It, can be by combining from different intrusion UE using which_iDifferent R_iCarry out the aggrieved UE with intra-cell interference Difference may combine and constructed.In principle, which can not need highdensity NZP CSI-RS.

For based on using other UE NZP CSI-RS channel estimation and interference simulation intra-cell interference measurement and Speech, a problem is expense, especially when the quantity of the UE dispatched jointly increases.

In order to reduce expense, disclosed some embodiments are provided is joined using the wave beam management by the TRP broadcast in cell Examine the solution for the IMR that signal is measured as intra-cell interference.

Fig. 2 is to show according to disclosed some embodiments for managing reference signal based on periodical downlink wave beam The flow chart of the operation of the interference measurement of (DL BM-RS).

In 5G or NR system, wave beam management will execute at both the side TRP and the side UE place, to obtain and maintain for communicating Best TRP and UE wave beam.For downlink transfer, wave beam management may include three processes: P-1, P-2 and P-3.P-1 is Obtain initial TRP Tx (transmission) wave beam and UE Rx (reception) wave beam.P-2 is to realize TRP Tx beam optimization, and P-3 is Realize UE Tx beam optimization.For downlink wave beam management process P-1, TRP needs periodically small to being serviced by TRP UE broadcast beam in area shapes reference signal.

As described above, aggrieved UE is based on the letter using the NZP CSI-RS for being sent to intrusion UE in the scene of MU-MIMO It can be suitable that road estimation, which executes intra-cell interference measurement with interference simulation,.However, which can lead to a large amount of expenses, because The quantity of the UE dispatched jointly increases.

In the scene of MU-MIMO, DL BM-RS is broadcast periodically by TRP to cell in wave beam management process P-1 Interior UE is for initial wave beam acquisition.For example, DL BM-RS may include CSI-RS or demodulated reference signal (DM-RS).Cause To be beam forming for the CSI-RS of wave beam management process P-1 and be periodically sent to UE, it is based on non-zero power, CSI-RS for wave beam management process P-1 also is used as the periodical IMR based on NZP CSI-RS.That is, can be by being existed by TRP During wave beam management process P-1 service life NZP CSI-RS come realize intra-cell interference measure.In this way, can reduce in cell The expense of interference measurement, because the purpose that need not be measured for intra-cell interference distributes individual CSI-RS.

Using the NZP CSI-RS of wave beam management process P-1, can simplify in the cell based on channel estimation and interference simulation Interference measurement, because being sent to the NZP CSI-RS of corresponding intrusion UE to known to aggrieved UE.For MU-MIMO operation, TRP can indicate that the interference from which intrusion UE should be measured to aggrieved UE, or in other words, which NZP CSI-RS should be measured.By Evil UE will be based on the NZP CSI-RS measurement interference for being sent to corresponding intrusion UE, and to TRP feedback interference measurement result.Needle Instruction to the NZP CSI-RS to be measured of interference is UE dedicated, and can dynamically be changed.If not indicating NZP CSI- RS, then then aggrieved UE should not execute interference measurement based on periodicity NZP CSI-RS.Otherwise, UE should be based on corresponding as indicated NZP CSI-RS execute interference measurement.

Specifically, at 205, TRP 111 can be to the UE broadcast periodicity BM-RS in cell.Periodical BM-RS will be in wave It is used to execute the initial beam acquisition for the corresponding UE in cell by TRP 111 during beam management process P-1.

At 210, UE 101 can will be decoded from the received periodicity BM-RS of TRP 111 to realize just convenient for TRP 111 The acquisition of beginning wave beam.

Meanwhile according to some embodiments, these periodicity BM-RS also acts as the IMR of UE 101 to execute in cell Interference measurement.

Correspondingly, at 225, UE 101 can measure other UE's in cell based on decoded periodicity BM-RS Intra-cell interference.For example, BM-RS may include periodical NZP CSI-RS.

For the low-density for keeping the CSI-RS for interference measurement, one or more intrusions can be utilized based on as described above The channel estimation and interference simulation of the NZP CSI-RS of UE measures the intra-cell interference of aggrieved UE (such as UE 101).

Specifically, UE 101, which can be used, is sent to intrusion UE_iNZP CSI-RS come estimate by from intrusion UE_iIt is dry The characteristic of channel of the UE 101 disturbed (is expressed as H_i).Then UE 101 can get as R_i=H_i*H_i ^HIntra-cell interference, wherein (·)^HFor transposition conjugate operation.

Then at 230, UE 101 can be reported to TRP 111 comes from each intrusion UE_iMeasurement interference (i.e. R_i)。TRP The 111 executable any combination of interference simulations for intrusion UE, and then determine the appropriate ways of processing interference.Optionally Ground can execute interference simulation in the side UE.In this case, UE 101 produces jamming report, the jamming report include one or The interference of certain combined measurements of multiple intrusion UE, and jamming report is sent to TRP.

Because some can lead in other UE only in cell interferes significantly with aggrieved UE, aggrieved UE be may be selected The subset of other UE in cell measures intra-cell interference or TRP as intrusion UE and can indicate in aggrieved UE selection cell The subset of other UE measure intra-cell interference as intrusion UE.Correspondingly, the corresponding of decoded BM-RS may be selected in aggrieved UE Subset measured as IMR other UE in cell selection subsets intra-cell interference.

As shown in Fig. 2, at 220, other corresponded in cell are may be selected in UE 101 before measuring intra-cell interference It is done in cell of the subset of the decoded BM-RS of the selection subsets of UE to measure the selection subsets of other UE in cell It disturbs.

In some embodiments, UE 101 can should be measured in cell based on the expectation of UE 101 itself, determination The interference of which of other UE is simultaneously it is thus determined which of decoded BM-RS application acts on intra-cell interference measurement IMR。

In some embodiments, UE 101 can select to measure for intra-cell interference according to the instruction from TRP 111 Decoding BM-RS subset.For example, as shown in Fig. 2, TRP 111 can encode instruction, and send and compile to UE 101 at 215 The instruction of code is to indicate to measure the interference of which of other UE in cell.Because each UE in cell has UE Dedicated corresponding wave beam manages reference signal, and the instruction from TRP actually indicates which BM-RS application acts on measurement UE Intra-cell interference IMR.Then according to the instruction from TRP, the subset of decoded BM-RS is may be selected to measure and in UE 101 From the intra-cell interference of the respective subset of other UE in cell.In some embodiments, instruction can be dedicated for UE, and It can be by TRP 111 via higher level signaling or Downlink Control Information (DCI) dynamic configuration.

It, can be by the way that each different intrusion UE will be come from using the operation in the flow chart of Fig. 2_iAcquisition disturbance R_iTo measure the intra-cell interference that may be combined come the difference of the intrusion UE indicated freely by TRP 111 at aggrieved UE.

Fig. 3, which is shown, to be shown according to the interference measurement based on periodical DL BM-RS of disclosed some embodiments with what is reported Example time diagram.As shown, BM-RS periodically reports the UE into cell by TRP.If aggrieved UE is received from TRP and is used In instruction of the instruction for the subset of the BM-RS of intra-cell interference measurement, then aggrieved UE should execute cell based on the subset of BM-RS Interior interference measurement and the interference that measurement is periodically reported to TRP.Otherwise, if do not indicated for intra-cell interference measurement BM-RS, then UE should not execute intra-cell interference measurement based on periodicity BM-RS.

Because the reference signal for wave beam management process P-1 is periodically reported the UE into cell, period Property execute the intra-cell interference measurement based on P-1BM-RS, and periodically send jamming report to TRP.Disclosed one In a little embodiments, aggrieved UE can be based on semi-continuous downlink wave beam management reference signal rather than periodicity DL BM-RS implementation is small Interference measurement is for improving adaptability in area.

Fig. 4 is the operation for the interference measurement based on lasting DL BM-RS shown according to disclosed some embodiments Flow chart.Operation 405,410,415,420 and 430 in the flow chart of Fig. 4 be in the flow chart of Fig. 2 operation 205, 210, the identical operation in 215,220 and 230, and specific embodiment party relevant to these operations therefore will be omitted for brevity Formula.Different from the interference measurement of the periodical BM-RS based on Fig. 2, in Fig. 4, at 435, TRP 111 can control UE 101 logical It crosses and trigger signal is encoded and the trigger signal of coding is sent to UE 101 to execute or stop interference measurement.Correspondingly, In At 425, UE 101 may be in response to be based on doing in BM-RS measurement cell for the trigger signal for notifying UE 101 to execute interference measurement It disturbs, or stops intra-cell interference measurement in response to the trigger signal for notifying UE 101 to stop interference measurement.In this case, Periodically for the BM-RS of wave beam management process P-1, the IMR as aggrieved UE is dry in cell to execute for greater flexibility semi-continuously Disturb measurement.

Fig. 5, which is shown, to be shown according to the interference measurement based on semi-continuous DL BM-RS of disclosed some embodiments with what is reported Example time diagram.As shown, aggrieved UE may be in response to receive the triggering letter for notifying aggrieved UE to execute or stop interference measurement Number execute or stop the interference measurement based on periodical P-1BM-RS.

For improving the another way for the adaptability that intra-cell interference measures using for wave beam management process P-2 The IMR that BM-RS is measured as the intra-cell interference for aggrieved UE.Wave beam management process P-2 is optimization for downlink transfer TRP Tx wave beam.During process P-2, TRP sends the wave beam to be measured by UE and manages reference signal (such as CSI-RS), and UE needs the signal of feedback reception to complete beam optimization.Process P-2 can be periodically carried out.In other words, TRP can be in process P- To the BM-RS of UE broadcast half period property during 2.It is similar with the P-1 periodicity BM-RS measured for intra-cell interference, the half period Property BM-RS also can be used as UE IMR reuse with execute intra-cell interference measurement.

Fig. 6 is the operation for showing the interference measurement based on half period property DL BM-RS according to disclosed some embodiments Flow chart.Operation in the flow chart of Fig. 6 is similar with the operation in the flow chart of Fig. 2, the difference is that P-2 half period property BM- RS rather than P-1 periodicity BM-RS are used as the IMR of intra-cell interference measurement.It will thus omit and the operation phase for brevity The specific embodiment of pass.

Because intra-cell interference will be measured based on P-2 half period property BM-RS, report in cell to UE half period property Interference.For example, the trigger signal that UE may be in response to be configured to triggering interference measurement by TRP measures and reports intra-cell interference. Fig. 7 was shown according to the interference measurement based on half period property DL BM-RS of disclosed some embodiments and the example time of report Figure.It is measured as shown, the half period property NZP CSI-RS for the management of P-2 wave beam is also indicated as intra-cell interference Half period property IMR.In this way, the adaptability of intra-cell interference can be further increased, and can reduce for intra-cell interference Expense.

Other than above-mentioned intra-cell interference, UE can also be by the interference of other UE in neighboring community, especially When UE and TRP works in duplexing (TDD) mode of dynamic Time Division.In dynamic tdd mode, the downlink transfer of the UE in cell It can be by the interference of the uplink of other UE in neighboring community.Sometimes other UE's in neighboring community is dry It disturbs more significant than the intra-cell interference of UE.Therefore the channel status more accurately to estimate the UE in dynamic tdd mode Information, it can be necessary for measuring the interference of other UE in neighboring community.

In 5G the or NR system for supporting MU-MIMO operation, UL wave beam management has been considered as maintaining good UE-TRP wave Beam pair.For can directly reuse DL Rx wave beam as UL Tx wave beam with the corresponding UE of wave beam, UE.However, for not For those of wave beam correspondence, some uplink beam scan operations should be used to help UE and determine optimal UL Tx wave beam. In addition in the side TRP, in the corresponding situation of no wave beam, TRP can not be readily determined which wave beam to receive UL signal using. Therefore, it will be corresponded to for certifiable part or do not guarantee that corresponding situation supports the management of UL wave beam.

Similar with the management of DL wave beam, UL wave beam management reference signal is for executing UL wave beam management.Equally, by neighboring community In the UL wave beam management reference signal that sends of other UE also be used as the interference that UE measures other UE in neighboring community IMR.

In some embodiments, recommend to manage reference signal and downlink wave beam management ginseng by reusing uplink beam Both signals are examined as the IMR of UE 101 to measure interference.Fig. 8 is to show according to disclosed some embodiments for being based on Uplink beam manages the flow chart of the operation of the interference measurement of both reference signal (UL BM-RS) and DL BM-RS.

At 810, it may be determined that whether UE 101 and TRP 111 operate in dynamic tdd mode.If they are not dynamic It is operated in state tdd mode, then UE 101 can be based only upon DL BM-RS as described above and measure other UE in same cell Intra-cell interference.Specifically, UE 101 can decode the DL BM-RS broadcasted by TRP 111 to be used for 815 DL wave beam Management, and the then intra-cell interference of other UE at 820 based on decoded DL BM-RS measurement in same cell. For the details of operation 815 and operation 820, the description about foregoing embodiments as shown in Figures 2 to 7 can refer to.

If UE 101 and TRP 111 are operated in dynamic tdd mode, other UE's in neighboring community is dry Disturbing to be main interference source, and therefore needs to measure so that total interference is estimated in accuracy.Therefore, at 825, UE 101 The UL BM-RS sent by other UE in neighboring community can be decoded to be used for UL wave beam management.As an example, UL BM-RS It may include detection reference signal (SRS), Physical Uplink Control Channel (PUCCH) signal or Physical Random Access Channel (PRACH) Signal.Then, UE 101 can measure the dry of other UE in neighboring community using decoded UL BM-RS as IMR It disturbs.

Adequately measure other UE in same cell or other UE in neighboring community to the total of UE 101 Interference, is contemplated that the problem of the synchronization about network (such as RAN 110).If Network Synchronization (i.e. cell and neighboring community It is synchronous), then UE 101 can be identical fixed with based on the intra-cell interference of other UE in DL DM-RS measurement cell at 835 At present the interference of other UE in neighboring community is measured using UL DM-RS as IMR.Otherwise, if network is asynchronous (i.e. cell and neighboring community is asynchronous) can determine measurement gap at 840 based on the timing difference between cell and neighboring community. Herein, measurement gap is other UE of the timing and measurement of the interference of other UEs of the measurement in cell in neighboring community Interference timing between gap.Then UE 101 can be in the timing and survey according to determining measurement gap scheduling at 845 It measures and other in neighboring community is measured based on decoded UL BM-RS at the timing of the interference of other UE in cell The interference of UE.

In this way, in dynamic tdd mode, other in cell of DL BM-RS and UL BM-RS measurement can be utilized respectively Both the interference of UE and the interference of other UE in neighboring community.As a result, UE 101 can be reported to TRP 111 at 850 Both the interference of other UE in cell and the interference of other UE in neighboring community.
