Wireless communication method and apparatus for minimizing overhead signaling and optimizing radio resource utilization
First Claim
1. A method of minimizing overhead signaling and optimizing radio resource utilization, the method comprising:
- determining a first subset of a plurality of user equipment mobile terminals (UEs) that have pending downlink transmissions;
determining a second subset of the plurality of UEs that do not have pending downlink transmissions;
transmitting a request to each of the UEs in the first subset to begin channel quality (CQ) measurements, whereby a request to begin CQ measurements is not sent to any of the UEs in the second subset; and
receiving CQ measurement results from each of the UEs in the first subset in response to the request to begin CQ measurements.

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.
