Technical Field

The embodiment of the disclosure relates to the technical field of internet, and in particular relates to a space division multiple access method and device under a super cell, electronic equipment and a computer readable medium.

Background

With the continuous Evolution of communication technology, the LTE (Long Term Evolution) system is widely researched and gradually applied to a commercial network. The LTE system provides a higher data transmission rate, a lower transmission delay, and a better service quality for users based on core technologies such as OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple-Input Multiple Output). Super-cells (Super-cells) are a form of cells in the LTE system, and each Super-Cell is composed of a plurality of CP (Cell-Portion, sub-Cell unit). Each CP shares super Cell resources including Cell identification (Cell ID), time domain resources, frequency domain resources, etc., and multiple CPs can jointly process signals of the same user.

In an SDMA (Spatial Division multiple Access) method in a super cell in the prior art, mutual interference between an active subscriber and a secondary subscriber is measured, and only when the mutual interference between the active subscriber and the secondary subscriber is smaller than a certain threshold value, space Division multiple Access can be performed, so that the matching rate of the active subscriber and the secondary subscriber meeting the condition is not high, and therefore the probability that the subscriber can perform space Division multiple Access is low. In addition, in the existing SDMA method, the master subscriber and the slave subscriber must occupy the same time-frequency resource, thereby limiting the flexibility of resource allocation.

UE 8; it should be understood that the number of UEs in the super cell is not limited to 8.

Fig. 2 is a flowchart of a space division multiple access method according to an embodiment of the present disclosure.

In a first aspect, an embodiment of the present disclosure provides a space division multiple access method, as shown in fig. 2, the method includes the following steps:

and S1, acquiring the active set of the sub-cell unit CP of the terminal.

In step S1, the cell master CP acquires the CP in the current state of each terminal UE, and generates an active set of CPs for each terminal.

Specifically, as shown in fig. 1, both UE1 and UE5 are located in CP 1; UE2 and UE6 are located in CP 2; the UE3 is located at the intersection of CP1 and CP 2; the UE4 is located at the intersection of CP1 and CP 3; the UE7 is located at the intersection of the CP1, CP2 and CP 3; the UE8 is located at the intersection of CP2 and CP 4; that is, the CP active set of UE1 includes CP 1; the CP active set of UE2 includes CP 2; the CP active set of UE3 includes CP1, CP 2; the CP active set of UE4 includes CP1, CP 3; the CP active set of UE5 includes CP 1; the CP active set of UE6 includes CP 2; the CP active set of UE7 includes CP1, CP2, CP 3; the CP active set of the UE8 includes CP2, CP 4.

S2, dividing terminals with the CP number of 1 in the CP active set into null packets; and (4) enabling the number of the CPs in the CP active set to be larger than 1 to be in the frequency division group.

In step S2, the cell master CP divides UEs with CP number 1 in the CP active set into null packets, where the UEs in different CPs are located in different layers, and space division multiplexing is performed between the layers; and the cell main CP enables the number of the CPs in the CP active set to be larger than 1 to be frequency division grouped.

Specifically, also taking the example in step S1 as an example, the CP active set of the UE1 includes CP 1; the CP active set of UE2 includes CP 2; the CP active set of UE5 includes CP 1; the CP active set of UE6 includes CP 2; UE1, UE2, UE5, and UE6 are thus divided into null packets, with UE1 and UE5 located in the same layer, and UE2 and UE6 located in the same layer.

The number of CPs in the CP active set for each of the UE3, UE4, UE7, and UE8 is plural, and therefore, the UE3, UE4, UE7, and UE8 are divided into frequency division groups.

S3, controlling the scheduling of the terminals in the null packet by the CP to which they belong, and scheduling the terminals in the frequency packet.

In step S3, the cell master CP controls the CP corresponding to each UE in the null packet to schedule the UE, and schedules the UE in the frequency packet.

Specifically, also taking the examples in steps S1 and S2 as an example, the cell master CP controls CP1 to schedule UE1 and UE5, and CP2 to schedule UE2 and UE 6; meanwhile, the cell master CP schedules UE3, UE4, UE7, and UE 8.

In the embodiment of the disclosure, according to the number of the CPs in the CP activation set of the UE, the UE with the CP number of 1 is divided into the null packets, and the control division multiplexing without interference is performed between the UEs, and at this time, the UEs can be directly scheduled through the CPs, so that the scheduling pressure of the cell main CP can be effectively relieved, that is, the requirement on the scheduling capability of the cell main CP is not too high. Meanwhile, if the CP active set of one UE only includes 1 CP, it may be estimated that the UE is located in the middle of the CP, and if the CP active set of one UE includes 2 or more than 2 CPs, it may be estimated that the UE is located at the edge of the CP at this time.

In some embodiments of the present disclosure, step S1 may specifically include: for each UE in the super cell, the base station acquires all CPs corresponding to the UE. The signal values of the UE received by all the CPs corresponding to the UE are different, some CPs have high communication performance with the UE and some CPs have low communication performance with the UE, and the CPs with high communication performance with the UE are judged as the active CPs of the non-scheduling users; otherwise, the UE is determined to be the non-active CP of the UE. And taking the determined set of the active CP of the UE as the CP active set of the UE.

The number of RBs of UE1, UE2, and UE5 will be described as an example.

In step S31, the cell master CP may sequence the QoS of each UE, generate QoS queue information, and send the QoS queue information and the terminal information of each UE in the null packet to the CP corresponding to the terminal in the null packet, specifically send the middle terminal information of UE1 and UE5 to CP1, and send the terminal information of UE2 to CP 2; then, the CP1 estimates the number of RBs of the UE1 and the UE5 according to the QoS queue information and the middle terminal information of the UE1 and the UE 5; the CP2 may then be based on the QoS queue information and the number of RBs of the UE 2. Of course, at the same time, the cell master CP will frequency-group the number of RBs required for each UE according to the QoS queue information and the terminal information of each UE.

In some embodiments of the invention, the terminal information may include a requested bandwidth and/or a baseband channel quality of the terminal. The CP1 estimates the number of RBs for UE1 and UE5 based on the QoS queue information and the requested bandwidth and/or baseband channel quality.

S32, the number of RBs of each terminal and the position of the terminal are allocated according to the number of RBs of the terminal.

In step S32, the cell master CP receives the RB number of each UE of the null packet sent by the CP corresponding to each UE of the null packet, and at this time, the cell master CP allocates the RB number and position of the UE according to the RB number of each UE in the null packet and the frequency packet.

It should be noted that the CP of the null packet UE sends the number of RBs required by each UE to the cell master CP, the cell master CP needs to reallocate the number of RBs of each UE according to the QoS queue information of each UE, and the allocation result may be the same as or different from the number of RBs estimated by the CP of the null packet UE.

S33, controlling the CP to which the terminal in the null packet belongs to dispatch the terminal according to the number and position of the distributed RB, and dispatching the number and position of the RB distributed by the terminal in the frequency packet.

In step S33, after the cell master CP allocates the number and location of RBs to the CP of each null-packet UE, the CP schedules the UE according to the allocation of the cell master CP. At this time, the CP of the null packet UE may be null or frequency-divided according to the number and location of RBs, for example, UE1 and UE5 do frequency division within CP1, and UE2 and UE6 do frequency division within CP 1.

In order to make the space division multiple access method in the super cell more clear in the embodiment of the present disclosure, an access method in the UE moving process is described below.
