Methods and apparatus for facilitating inter-cell interference coordination via over the air load indicator and relative narrowband transmit power

摘要

Systems and methods for facilitating inter-cell interference coordination using resource partitioning are described. A UE may receive or determine information related to received interference and/or future scheduling. The information may be communicated to a serving base station, which may use the information to allocate uplink or downlink resources between cells. The uplink and/or downlink resource may be partitioned in subbands to mitigate interference from adjacent network nodes. The eNBs may communicate, such as directly, via a backhaul connection, and/or between UEs to configure interference coordination and signaling.

主权项

1. A method for interference mitigation in a wireless communication system, the method comprising:
determining interference information applicable to at least one of a serving cell and a neighbor cell, the interference information relating to at least one of an interference value corresponding to an amount of uplink interference experienced at a serving base station in the serving cell, or resources to be used in transmitting one or more downlink signals from the neighbor cell; scheduling signal transmission within the serving cell based at least in part upon the interference information; and communicating a resource partitioning request to one or more nodes in the neighboring cell.
