Characterization of co-channel interference in a wireless communication system, in particular a cellular radio communication system

摘要

A method for characterizing interference in a radio communication system including a plurality of user equipment communicating with transceiver stations, includes: determining quantities indicative of interference (attenuation or power) experienced by a transceiver station interfered by interfering user equipment; and exchanging between transceiver stations information based on these quantities and concerning interference from the interfering user equipment. In particular, the user equipment is in communication with respective serving transceiver stations, and exchanging includes sending from the serving transceiver stations to the interfered transceiver stations information concerning interference from user equipment served by the serving transceiver stations and interfering with the interfered transceiver stations. The method further includes grouping, by the serving transceiver station, the interfering user equipment according to a given grouping criterion in order to form groups thereof.

1. A method for characterizing interference in a radio communication system comprising a plurality of user equipment configured to communicate with a plurality of transceiver stations, the method comprising:
determining quantities indicative of interference experienced by a transceiver station interfered with by an interfering user equipment, wherein:
the interfering user equipment is served by a serving transceiver station which is different from the interfered-with transceiver station; andthe quantities indicative of interference comprise attenuations of signals experienced by pilot signals carrying cell-specific training sequences and propagating between the interfered-with transceiver station and the interfering user equipment; exchanging between the serving transceiver station and the interfered-with transceiver station information concerning interference from the interfering user equipment, wherein the information concerning interference includes the attenuations of signals and interfering transmission powers that the interfering user equipment uses to transmit, and wherein the exchanging includes sending the interfering transmission powers that the interfering user equipment uses to transmit from the serving transceiver station to the interfered-with transceiver station; and receiving, by the serving transceiver station, a request from the interfered-with transceiver station for reducing the interfering transmission powers that the interfering user equipment uses to transmit.
