Embodiment Construction

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0016] Such as figure 1 Shown is the first flow chart of the uplink MIMO scheduling method of the present invention.

[0017] Step S100, setting a first-type period and a second-type period for the base station to determine a scheduling grant value.

[0018] Specifically: the base station determines the maximum scheduling for sending by the user equipment according to the currently measured signal-to-noise ratio and load. Due to the change of the signal-to-noise ra...

Abstract

The invention discloses an uplink multiple input and output scheduling method, which includes the following steps: setting a first type cycle and a second type cycle. In the first type period, it is judged whether the single-stream throughput is greater than the dual-stream throughput. If the single-stream throughput is greater than the dual-stream throughput, the data stream is single-stream, and the first single-stream scheduling grant value is sent to the user equipment. If the single-stream throughput is less than the dual-stream throughput, the data stream is dual-stream, and the dual-stream scheduling authorization value is sent to the user equipment. In the second-type period, in the second-type period, determine a second single-stream scheduling grant value according to the single-stream throughput, and send the second single-stream scheduling grant value to the user equipment. The invention also discloses a base station and user equipment. The uplink multiple input and output scheduling method, base station and user equipment disclosed in the present invention accurately and simply determine the scheduling authorization value required for sending data, and ensure the performance of multiple input and multiple output.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an uplink MIMO scheduling method, base station and user equipment. Background technique [0002] The multi-antenna technology is one of the important technologies for increasing the peak rate of users, and is a solution for further increasing the peak rate of users in the uplink of UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System). Since UMTS is a self-interference system, the network schedules each UE (User Equipment, User Equipment) based on the interference level of the air interface, and ensures the quality of service and network capacity of the network through reasonable allocation and use of air interface resources. Specifically, the NodeB (base station) will measure the real-time load and compare it with the target load. Through a certain load control algorithm, determine the maximum power that the UE can currently tra...
