DYNAMIC CHANNEL QUALITY MEASUREMENT PROCEDURE IMPLEMENTED IN A WIRELESS DIGITAL COMMUNICATION SYSTEM TO PRIORITIZE THE FORWARDING OF DOWNLINK DATA
First Claim
1. A method for receiving downlink control information, the method comprising:
- receiving by a user equipment (UE) a request to provide a channel quality (CQ) measurement report;
transmitting by the UE a CQ measurement report in response to the request;
receiving by the UE downlink control information including an allocation of resources, wherein the downlink control information is distinguished by a UE identity (ID) associated with the UE; and
receiving by the UE downlink data in accordance with the allocation of radio resources.

Abstract
A wireless digital communication system includes a base station in communication with a plurality of user equipment mobile terminals (UEs). The system prioritizes the forwarding of blocks of downlink data to designated ones of the UEs. The system employs adaptive modulation and coding (AM&C) to achieve improved radio resource utilization and provides optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink (DL) channel quality measurements only from those mobile terminals (UEs) 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 indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.
