Dynamic channel quality measurement procedure implemented in a wireless digital communication system to prioritize the forwarding of downlink data
First Claim
1. A method of requesting a channel quality measurement report, the method comprising:
- transmitting a request to provide a channel quality (CQ) measurement report, wherein the request to provide a CQ measurement report is associated with a specified radio resource upon which the corresponding CQ measurement is to be based, and wherein the request to provide a CQ report is transmitted on a common control channel shared by user equipments (UEs) in a cell;
receiving a CQ measurement report in response to the request;
transmitting, on the common control channel, an allocation of radio resources that is based on the transmitted CQ measurement report; and
transmitting 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.
