Embodiment 1

[0037] (1) The base station sends the interference control function selection indication signaling in the control channel, wherein the interference control function selection indication signaling includes two parts: indication information of whether the interference control function is enabled or not and index information of the selected interference control function. A signaling format of the interference control function selection indication signaling is shown in Table 1.

Abstract

A method and a terminal for transmitting and receiving the indication signaling of an interference control function. The method includes that a base station sends the indication signaling of the interference control function to the terminal through a downlink channel in order to notify the terminal of the configuration information of the interference control function. According to the method, the terminal needs not to perform a tedious calculation process when inter-cell interference intensity is decreased, thus the system load is reduced and the signaling interaction times between the base station and the terminal is decreased and the signaling cost is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for sending and receiving an interference control function instruction signaling, and a terminal. Background technique [0002] In a data transmission system that uses a base station for scheduling control, the scheduling and allocation of all system resources is usually performed by the base station, for example, the resource allocation when the base station performs downlink transmission and the resources that the terminal can use when performing uplink transmission, etc. Assigned by base station scheduling. [0003] In an Orthogonal Frequency Division Multiplexing (OFDM) system, when a base station and different terminals perform downlink data transmission in the same cell, since these downlinks are orthogonal to each other, it is possible to avoid interference. However, downlinks between different cells may not be orthogonal, so each terminal may suffer downlink i...
