OPEN LOOP CHANNEL REPORTING IN A WIRELESS COMMUNICATION SYSTEM

摘要

wireless communication system in channel quality indicator (CQI) reporting to the technology for It is described. In one design, UE, based on the assumption of a set of pre-coding matrix that is used by the base station for data transmission to the UE determines the CQI. The base station may not actually use or using a set of precoding matrices that are assumed by the UE. The UE transmits the CQI to the base station, and thereafter, receives the data transmission sent by the base station based on the CQI. In one design, UE is the time available for data transmission to the UE - to determine the set of precoding matrices for the set of frequency resources. The UE that time - on the basis of the pre-coding matrix for the frequency resources each time-determining received signal quality of the frequency resources. Next, UE is time - based on the received signal quality of the frequency set of resources and determines the CQI ;
