Abstract

A Coordinated Multipoint (CoMP) cell controller performs network centric link adaptation for User Equipment (UE) in the CoMP cell. The CoMP cell controller receives at least infrequent channel estimates from a UE in the CoMP cell from which it estimates downlink channel and thermal noise at the UE. The CoMP cell controller is aware of the desired signal to be received at the UE and the intra CoMP cell interference to the UE caused by transmissions to other UEs in the CoMP cell. The CoMP cell receives from the UE reports of inter CoMP cell interference caused by transmissions by other CoMP cells. Based on the downlink channel quality the desired signal the intra CoMP cell interference the inter CoMP cell interference and the thermal noise the CoMP cell controller performs link adaptation by selecting modulation and coding schemes and other transmission parameters for an upcoming transmission duration (such as a TTI).
