DISTRIBUTED BUFFER STORE BASED UPLINK COORDINATED MULTIPOINT COMMUNICATIONS

摘要

A method and system for providing CoMP assistance in a wireless communication network are disclosed. A cooperating base station receives a CoMP assistance request from a serving base station. The CoMP assistance request is a request for assistance to decode a first transmission from a UE. The cooperating base station receives the first transmission from the UE. The first transmission from the UE is received at the cooperating base station at one of a time before receiving the CoMP assistance request and a time after receiving the CoMP assistance request. The cooperating base station determines a CoMP payload in response to the CoMP assistance request. The CoMP payload is based on the received first transmission from the UE. The CoMP payload is forwarded to the serving base station after the serving base station determines that the first transmission from the UE is received by the serving base station with error.
