Problems solved by technology

[0004] The RR algorithm can guarantee the fairness between users to a certain extent, but the RR algorithm does not take into account the specific conditions of the wireless channels of different users, so the throughput of the SDMA system is relatively low

Embodiment Construction

[0035] The method and system described in the embodiments of the present invention will be described in detail below.

[0036] First, the method of the present invention is described in detail.

[0037] The method of the present invention mainly includes: obtaining the maximum number of transmission bits of multiple users according to the effective post-processing signal-to-noise ratio and channel gain matrix of multiple users respectively;

[0038] Determine the user to be transmitted according to the maximum number of transmission bits of the plurality of users;

[0039] Perform user pairing on the user to be transmitted to obtain a transmission user pair, and the output user pair simultaneously transmits data;

[0040] and updating the average transmission rates of the plurality of users.

[0041] Specifically as shown in Figure 1, the set of resource blocks is set as U, and for all resource blocks, resource allocation is performed according to the following steps, and th...

Abstract

The invention is concerned with the dispatching method of the space division multiple access (SDMA) system. It is: obtaining the most transmission bit number of the users according to the efficiency post processing signal-to-noise ration (SNR)Ëðand the channel gaining matrix; Confirming the transmission user on hold according to the most transmission bit number of the users; Conducting user pairing to the transmission user on hold to get the transmission user couple and transmitting information at the same time; Ensuring and renewing the average transmission rate of the users. The invention improves the throughput of the SDMA system and with zero effect to the users.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to the technical field of multi-user scheduling in an SDMA (Space Division Multiple Access) system. Background technique [0002] Multi-user scheduling is an effective way to allocate resources. A reasonable scheduling scheme can make full use of the multi-user diversity of the system and effectively improve the system throughput. In the SDMA system, there are two types of user scheduling: user pair scheduling and multi-user resource scheduling. For user pairing scheduling, consider the correlation characteristics between user channels, according to a certain user pairing method (such as random pairing RPS, orthogonal pairing OPS, determinant pairing DPS and post-processing SINR pairing SINR-PS, etc.); User resource scheduling, using a certain scheduling algorithm to allocate resources to the optimal user pair. [0003] At present, in the SDMA system, the RR (round robin) al...
