    Abstract: DYNAMIC CHANNEL QUALITY MEASUREMENT PROCEDURE FORA wireless digital communication method for communicating between abase station and a plurality of user equipment mobile terminals (UEs) and employsadaptive modulation and coding (AM&C) to achieve improved radio resourceutilization and provide optimum data rates for user services. Blocks of downlink(DL) data are received by the base station which requests downlink DL channelquality measurements only from those mobile terminals (UEs) with pendingdownlink transmissions. The UEs respond to the request by measuring andreporting DL channel quality to the base station, which then allocates resourcessuch that the UEs will make best use of radio resources. The base station notifiesthe UEs of the physical channel allocation indicating fee modulation/coding rateand allocated slots followed by transmission of blocks of downlink data which aretransmitted to the UEs.Fig. 1.

    Abstract: An uplink signal may be transmitted by a user equipment (UE) in a time interval using an uplink control channel. The uplink signal may include hybrid automatic repeat request (H-ARQ) control information related to received downlink data. If the UE determines that information indicating a coding and modulation is to be transmitted at a same time interval as the H-ARQ control information, the uplink signal may include the information that indicates the coding and modulation.

    Abstract: In a wireless digital communication system which may employ CDMA 5 technology, a method and system for obtaining channel quality (CQ) measurements for downlink resource allocation wherein a User Equipment (UE) continuously measures RSCP based on a communication on a reference channel provided by the network. The UE measures timeslot ISCP either continuously, by configuration or by rotation and reports downlink CQ. The UE may report the 10 RSCP once and the ISCP per timeslot, or may report some function of the RSCP/ISCP ratio such as modulation parameters or combined coding of all timeslots. 3/3 50UE 1 BASE STATION L0 UE 12 STEP 54 MEASUREMENT OF ROVER A STEP 52 STE ~RSCP REFERENCE STEP 56 MEASUREMENT REPORT RECEIVE STEP 58 -+ WNNKT CQ -- DOWNUNK CQ STEP 60 MEASUREMENT MEASUREMENT TO DETERMINE STEP 62 REQUIREMENTS FOR TRANSMIISION TO FIGa 3 VE
