Problems solved by technology

When user equipment with different receiver capabilities performs MU pairing (i.e. mixed user MU pairing scenario), if the MU weight design scheme with equal status is used, on the one hand, the signal quality of user equipment with weak receiver capabilities will decrease, and on the other hand, the It will cause a waste of interference suppression capability of user equipment with strong receiver capability

Embodiment Construction

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention.

[0046] An embodiment of the present invention provides a signal transmission method, which can be applied to an LTE communication system, for example, a frequency division duplex (Frequency Division Duplexing, FDD) architecture system or a time division duplex (Time Division Duplexing, TDD) architecture system. The main application scenario is that there are multiple users with different receiver capabilities in a multi-antenna cell.

[0047] Such as figure 2 Shown is a schematic diagram of the application scenario based on the embodiment of the present invention. The number of antennas in a base station is 4, and MIMO downlink transmission can be realized through BF weight design...

Abstract

The embodiment of the present invention relates to a signal sending method, a signal receiving method, a base station, and user equipment. The method includes: the base station determines that the first user equipment is paired with N second user equipment on the first resource block according to the receiver capability of each user equipment. , N is a positive integer; the base station multiplexes the signal of the first user equipment and the signals of the N second user equipments on the first resource block and sends them. It can be seen from the above that the embodiment of the present invention not only protects the channel quality of the user equipment with weak receiver capability, but also uses the excellent interference suppression capability of the user equipment with strong receiver capability to maintain its own channel quality.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a signal sending method, a signal receiving method, a base station, and user equipment (User Equipment, UE). Background technique [0002] Modern wireless communication services have ever-increasing demands on network capacity and communication performance. In the past, methods such as increasing bandwidth, optimizing modulation methods, and code division multiplexing have limited potential to improve spectral efficiency. Therefore, a Multiple Input Multiple Output (Multiple Input Multiple Output, MIMO) communication system is proposed in a Long Term Evolution (Long Term Evolution, LTE) technology, and a spatial multiplexing technology is used to improve the efficiency of a used bandwidth. In order to further improve the capacity of the cell in high-load scenarios, a multi-user multiple input multiple output (Multi-User Multiple Input Multiple Output, MU-...
