Embodiment Construction

[0022] The present invention provides a resource allocation method for MU-MIMO user pairing, the design concept of the method is:

[0023] A. Sort the users to be scheduled according to their priority;

[0024] B. Match users in order of user priority from high to low, define the user with higher priority among the paired users as the primary pairing user, and define the user with lower priority as the secondary pairing user;

[0025] C. Determine whether the paired secondary users of the paired primary user to be scheduled exist, and if so, put them into the available paired user queue according to the pairing matching degree of the paired secondary users from high to low;

[0026] D. Perform resource allocation for the paired primary user, and define the allocated resources as available paired resources;

[0027] E. Allocating the available pairing resources to each secondary pairing user in the queue of available pairing users in sequence.

[0028] In order to make the te...

Abstract

The invention provides a resource allocation method for Multiuser-Multiple Input Multiple Output (MU-MIMO) user pairing. The method comprises the following steps of: A, sorting users to be scheduled according to user priority; B, sequentially pairing the users in the order of user priority from high to low, defining a higher-priority user in each user pair as a paired main user and defining a lower-priority user in each user pair as a paired auxiliary user; C, judging whether paired auxiliary users of the paired main users to be scheduled exist, and putting the paired auxiliary users in an available pairing user queue in the order of pairing matching degree of the paired auxiliary users from high to low if the paired auxiliary users of the paired main users to be scheduled exist; D, carrying out resource allocation for the paired main users and defining resource obtained from allocation as available pairing resource; and E, sequentially allocating the available pairing resource to all the paired auxiliary users in the available pairing user queue in a segmented way.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to multiple-input multiple-output technology, and in particular to a resource allocation method for MU-MIMO user pairing. Background technique [0002] Compared with a traditional single-input single-output (SISO, Single input Single output) system, a multiple-input multiple-output (MIMO, Multiple-input Multiple-output) system can achieve a higher data transmission rate and diversity gain. In the LTE standard, a downlink 4x4 antenna and an uplink 2x4 antenna configuration are adopted. In order to further improve spectrum efficiency, in LTE-Advanced, the antenna configuration is increased to 8x8 for downlink and 4x4 for uplink. In this way, the expected peak rate is 1Gbits / s downlink. [0003] In order to improve cell throughput and system capacity, LTE-A adopts multi-user MIMO (MU-MIMO) transmission mode technology. In the MU-MIMO downlink, the base station se...
