A wireless digital communication method for a plurality of user equipment
mobile terminals (UEs) to communicate with a base station. Adaptive
modulation and coding (AM&C) is used to achieve improved radio resource
utilization and provide 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.
