Interference coordination method and base station

摘要

An interference coordination method includes: receiving, by a base station, an interference indicator that is in at least one subframe and sent by a user equipment, where the interference indicator includes RSSIs that are received by the user equipment in the at least one subframe and of all blocks PRBs, or sorted index values of the RSSIs of all the PRBs; determining, by the base station, a first list of candidate user equipment identities with a highest priority according to the interference indicator and uplink resource allocation information in the at least one subframe of a serving cell; and determining, by the base station, that a communication link of a macro cell corresponding to an identity, in the first list of candidate user equipment identities, of a user equipment with smallest interference is a reusable resource for D2D communication.

主权项

1. An interference coordination method, comprising:
receiving, by a base station, an interference indicator that is in at least one subframe and sent by a user equipment, wherein the interference indicator comprises at least one of received signal strength indicators (RSSIs) that are received by the user equipment in the at least one subframe and that are of all physical resource blocks (PRBs), or sorted index values of the RSSIs of all the PRBs; determining, by the base station, a first list of candidate user equipment identities with a highest priority according to the interference indicator and uplink resource allocation information in the at least one subframe of a serving cell, wherein the serving cell is a cell managed by the base station and serving the user equipment, and wherein the first list of candidate user equipment identities comprises a candidate user equipment identity of the serving cell and interference information of a communication link of a macro cell corresponding to the candidate user equipment identity of the serving cell; and determining, by the base station, that a communication link of a macro cell corresponding to an identity, in the first list of candidate user equipment identities, of a user equipment with smallest interference is a reusable resource for device-to-device (D2D) communication.
