Problems solved by technology

However, if the uplink data received by the base station corresponds to multiple interfering user equipments, these interfering user equipments may not be scheduled at the downlink scheduling time of the base station, so that the effect of suppressing interference will not be achieved

Abstract

Disclosed in the embodiment of the present invention are a method and system for scheduling channel resources and a base station, which apply to the technical field of communications. In the present embodiment, a base station first pre-schedules user equipment (UE) corresponding to a downlink resource in at least one subframe before scheduling an uplink resource, so as to obtain information of the pre-scheduled UE, said information being referred to when scheduling the uplink resource, then sends the scheduled uplink resource information to the scheduled UE by means of an uplink authorization; when the uplink channel information of the UE is received, a downlink transmission weight for Null Forming (NF) is calculated; when at least one pre-scheduled subframe arrives, the downlink frequency band of the UE is scheduled to be the same frequency band as that by which the UE sends uplink channel information; the downlink resource information is sent to the UE according to the calculated downlink transmission weight of the NF. According to the method in the present embodiment, interference between cells can be reduced and the effect of the NF on interference inhibition is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a channel resource scheduling method, system and base station. Background technique [0002] In the existing Long Term Evolution (LTE) communication network, when the base station uses the beamforming (Beam Forming, BF) technology to send downlink data, the received power of the user equipment can be improved, but this technology does not consider Interference to user equipment in neighboring cells. The use of Null Forming (NF) technology can reduce inter-cell interference. Specifically, it can be achieved by the following methods: [0003] After receiving the uplink channel data, the base station calculates the transmission weight of the downlink channel data sent by the base station according to the weight formula (1) of NF, so that when the base station transmits data according to the calculated transmission weight, the main lobe of the transmitted wavef...
