Abstract

The embodiment of the invention provides an interference detection method and device, and aims to report detected interference in time so as to coordinate transmission between a base station and user equipment. The interference detection method comprises the following steps: according to a result of modulus operation performed on an interference measurement period by a wireless frame counter and an interference measurement subframe index, determining a wireless frame and subframes in the wireless frame on which interference measurement is to be performed; working out average energy of subcarriers on at least one resource block; and comparing the average energy with a preset noise energy threshold value, and if the average energy is greater than the preset noise energy threshold value, reporting indication that the subframes to be subjected to interference measurement are interfered. By the interference detection method, the measurement time length, the measurement bandwidth, the measurement period and the reporting way can be flexibly selected, and a base station controller can coordinate the transmission between the base station and the user equipment according to interference instruction so as to avoid interference of a downlink signal of a remote base station on an uplink signal in a cell.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an interference detection method and device. Background technique [0002] The frame of a time division multiple access system is composed of multiple radio frames, and each radio frame contains multiple subframes, as shown in the attached Figure 1-a shown. in the attached Figure 1-a In the frame structure shown, subframe 0 (Subframe#0) is a downlink subframe, and subframe 2 (Subframe#2) is an uplink subframe, except subframe 0, subframe 2 and subframe 1 (Subframe#1). In addition, the uplink and downlink of other subframes can be determined according to the configuration. Subframe 1 is a special subframe, which has the function of uplink and downlink subframes. It includes the downlink pilot time slot (DwPTS) for transmitting downlink Orthogonal Frequency Division Multiplexing (OFDM) symbols. ), which also includes an uplink pilot time slot (UplinkPilot Time Slot...
