Problems solved by technology

If the network thinks that the user has performed interference cancellation and dispatched a higher MCS, but the user has not performed interference cancellation, the user's data may not be received accurately, and the performance will drop greatly
If the network thinks that the user has no interference cancellation and schedules a lower MCS, the user cannot achieve its due data rate, which will also affect system performance
[0013] In the prior art, the user receiving equipment obtains the transmission parameter information of its own data reception according to its own blind detection, and cannot eliminate the interference signal received by the user receiving equipment; even if the user receiving equipment is configured to receive the signal of interfering user equipment The transmission parameter information of the user equipment, the user receiving equipment uses the transmission parameter information of the signal that interferes with the user equipment to perform interference signal cancellation processing, which also changes dynamically, and cannot match the MCS scheduled by the network, thus affecting the data rate of the user receiving equipment and system performance.

Abstract

The invention provides a control information sending and receiving method, a network device and a receiving device, and relates to the field of communication. The method comprises the steps of obtaining a control instruction for processing a first signal, wherein the first signal carries the signal of not taking a receiving device as the target receiving device; and sending the control instruction to the receiving device, wherein the control instruction is used for controlling the receiving device whether to process the first signal. According to the scheme provided by the invention, a terminal whether to eliminate interference signals by employing transmission parameter information of the interference signals of a network notification can be controlled, and the data rate of the terminal is guaranteed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for sending and receiving control instructions, a network device and a receiving device. Background technique [0002] In a wireless communication system, the uplink and downlink communication of each user equipment is supported by a base station. In the downlink direction, the base station accessed by the user equipment sends the data of the user equipment to the user equipment through a downlink physical communication channel, and the user equipment demodulates the data sent to itself. [0003] There are multiple base stations in a wireless communication network, and different base stations can use the same frequency resource to perform downlink transmission at the same time point. When a base station transmits downlink data to users in its own cell, its downlink transmission signal may occupy the same time domain and frequency domain resources as downl...
