<P>PROBLEM TO BE SOLVED: To achieve improved radio resource utilization and provide optimum data rates for user services, by employing adaptive modulation and coding, in a wireless digital communication method for conducting communication between a base station (12) and a plurality of user equipment mobile terminals (UEs 30). <P>SOLUTION: Blocks of downlink (DL) data are received by the base station which requests DL-channel quality measurements only to those mobile terminals (30) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources, such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation that indicates the modulation/coding rate and allocated slots, followed by the transmission of blocks of downlink data to the UEs. <P>COPYRIGHT: (C)2010,JPO&INPIT |
