Example HARQ operation

Progress (such as NR) in communication can provide new feature, to realize in V2X communication and other types of communication Higher handling capacity.For example, in the shared certain V2X communications applications with automatic Pilot of such as sensor, the handling capacity of raising It may be important.

In NR, digital scheme is scalable (for example, with LTE on the contrary, in LTE, digital scheme is fixed).Example Such as, NR supports the use to orthogonal frequency division multiplexing (OFDM) symbol of different length.This feature can be used for supporting such as LBT's Resource contention mechanism, to provide improved system performance (for example, by interference during mitigating subframe).It should be noted that In Come in the NR in the communication scenes of dispatching communication without using central scheduler (for example, TRP), uses LBT or some like scheme It may be useful.In such scene, communication equipment can dispatch the transmission of their own (for example, such as compiling by exchange The information of bit rate, reference sequences, HARQ information etc.).

When the packet size for given transmission is greater than the size of a Transmission Time Interval (TTI), or when expectation When higher reliability (for example, using longer transmission time as cost), multiple HARQ transmissions are can be used in communication system.One In a little aspects, this disclosure relates to for supporting the skill of multiple HARQ transmissions or similar transmission (for example, other feedback procedures) Art.For purposes of illustration, these technologies will be discussed in the context of HARQ for being used for NR V2X.It should be understood, however, that , these introductions can be adapted for other types of communication system and feedback procedure.

In NR, the de-centralized access mechanism of transmitter can be related to: send LBT sequence, followed by SA, heel There are data.In certain aspects, LBT sequence instruction transmission has begun.LBT sequence also can indicate that transmission in current subframe The RB that will be used.In certain aspects, SA can carry the control information (example that receiver can be used to be decoded data Such as, code rate etc.).SA also can indicate that in subsequent transmission the RB that (for example, in subsequent subframe) will use.

In NR V2X, the information bit quantity in SA may not be fixed.For example, SA size can be big with grouping Small and/or HARQ transmission quantity zooms in and out.As another example, more OFDM symbols can be used for carrying SA information ratio Spy, to reduce efficient coding rate and the therefore reliability of increase SA transmission.In order to reduce the complexity (example of receiver side Such as, in order to avoid the blind decoding to SA must be carried out), it is expected that known SA OFDM symbol quantity.It can be by using listem-before-talk (LBT) process reserves SA and data resource.Therefore, it can be derived according to LBT process about SA symbolic number currently in use The information of amount.

Further, since HARQ transmission may span across several subframes, therefore exist for the mechanism for performing the following operation Demand: remain for the resource of the HARQ transmission in several subframes in advance, and provide to other equipment (for example, other UE) reserved Details, these equipment are decoded transmission.In some implementations, such mechanism should also be with It is mutually compatible in the resource reservation mechanism based on LBT of single sub-frame transmission.

As mentioned above, SA symbol quantity can be derived according to LBT process.Be below can be about this how Two examples completed.

In the first example, SA symbol quantity is defined based on reserved resource block (RB) quantity.For example, may exist Configurable thresholding (for example, by network configuration) so that if reserved RB quantity is greater than thresholding, SA symbol quantity be N (for example, 2).Otherwise, SA symbol quantity is (for example, 1) M.In certain aspects, which is to be based on observing that SA size is likely to It is zoomed in and out with packet size.Using the option, for identical reserved RB quantity, SA size can be rough identical , and it is unrelated with HARQ transmission quantity.

Second example is related to: using the specific LBT sequence (or other appropriate sequences) based on used SA symbol quantity. Herein, different LBT sequences can be defined, in systems to distinguish LBT sequence transmitted by distinct device (for example, difference UE Different LBT sequences can be randomly chosen).Expected receiver carries out the blind Detecting to the LBT sequence received, with determining pair The SA and RB of data distribution.Therefore, according to introduction herein, receiver, which is also based on transmitted specific LBT sequence, to be come SA symbol quantity used in determining.For this purpose, the set of all possible LBT sequence can be divided into such as two it is non-intersecting Set.In this example, for all sequences in a subset, SA symbol quantity to be used is (for example, 2) N, and is directed to All remaining sequences, SA symbol quantity to be used are (for example, 1) M.In other examples, different number can be used The SA symbol of LBT arrangement set and different number.

It is two examples of the pre- resource for remaining for multiple HARQ transmissions below.

First example is related to: remaining for the HARQ resource of multiple transmission in advance (for example, reserved in advance will be used in HARQ transmission Some or all HARQ transmissions subframe and RB).As an example, the resource of whole HARQ transmissions can be remained in advance. As another example, the resource of current HARQ transmission and next HARQ transmission can be remained in advance.It in other examples can be with Use other combinations.

Information about subframe and RB distribution to subsequent transmission can be according to the pass in used LBT sequence and SA It can be derived in the information of any single HARQ transmission.In certain aspects, (for example, including in SA) Hopping Pattern can be with It is used to indicate the resource that be used for different transmission.

In first example, transmitter (for example, UE) can be by the LBT money executed for the first HARQ transmission of such as getting off Source selection.LBT process may include selecting a random LBT timer " t " at the beginning of subframe.Then, transmitter is at it Start to wait " t " a LBT OFDM symbol before sending its LBT sequence.Transmitter is kept during " t " a LBT OFDM symbol It is mute.Therefore, before particular transmitter sends its LBT sequence, which can detecte the LBT sequence for sending them Other transmitters (for example, UE) (that is, other transmitters have selected for the LBT timer smaller than " t ") of column, and to keep away Exempt from RB used in those transmitters.Then, transmitter can be randomly chosen in remaining RB to send it above The resource of LBT sequence.The selected resource for LBT can be also used for SA and data transmission.

For any subsequent HARQ transmission, transmitter can choose fixed LBT timer " t "=0, rather than select with " t " timer value of machine.This may insure that beginning of the transmitter always in pre-selected resource in subframe starts to send. Select all other transmitter of the LBT timer greater than 0 that will detect the presence for sending transmitter in the burst. Therefore, these other transmitters can interfere to avoid with these HARQ transmissions.

Second example is related to: the resource for different HARQ transmissions is selected independently.In this case, for each HARQ transmission comes independently (for example, opportunism) selection RB resource and transmission subframe.The SA of each transmission can be indicated The no sum that use HARQ and HARQ transmission.In addition, the SA of subsequent HARQ transmission can be directed toward one or more previous SA Position and/or Data Position are to promote soft merging.For example, the second HARQ transmission may include the position about the first HARQ transmission The information of (for example, subframe used in the first HARQ transmission and RB).As another example, third HARQ transmission may include The information of position about the first HARQ transmission and the second HARQ transmission.As another example, third HARQ transmission be can wrap The information of the position about the second HARQ transmission is included, and the second HARQ transmission may include the position about the first HARQ transmission Information.Other combinations can be used in other examples.
