Dynamic Channel Quality Measurement Procedure for Adaptive Modulation and Coding Techniques

摘要

1. Technical Result Increase in efficiency of use of radio resources. 2. Essence A method for digital communication between a base station and a plurality of user equipment mobile terminals (UE) employs use of adaptive modulation and coding. Blocks of downlink (DL) data are received by the base station, which requests downlink DL channel quality measurements from mobile terminals with pending downlink transmissions. The UE 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 indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs. 3. Field of Application Digital radiocommunication systems.
