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

Abstract: A wireless digital communication method for communicating between a base station (12) and a plurality of user equipment mobile terminals (UEs 30) and employs adaptive modulation and coding to achieve improved radio resources utilisation 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 (30) 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.

Abstract: The present invention is related to a method and apparatus for implementing space frequency block coding (SFBC) in an orthogonal frequency division multiplexing (OFDM) wireless communication system. The present invention is applicable to both a closed loop mode and an open loop mode. In the closed mode, power loading and eigen-beamforming are performed based on channel state information (CSI). A channel coded data stream is multiplexed into two or more data streams. Power loading is performed based on the CSI on each of the multiplexed data streams. SFBC encoding is preformed on the data streams for each of the paired subcarriers. Then, eigen-beamforming is performed based on the CSI to distribute eigenbemas to multiple transmit antennas. The power loading may be performed on two or more SFBC encoding blocks or on each eigenmodes. Additionally, the power loading may be performed across the subcarriers or subcarrier groups for weak eigenmodes.

Abstract: The present invention relates to a detector that detects a transmitted digital signature using the energy output from a matched filter. The energies are tabulated according to an anticipated signature pattern for variable transmission distances. The tabulation accounts for expected round trip transmission delays and allows processing of the accumulated symbols to derive a correct signature whether coherent or signature coding is used and multiple Doppler channels are present.
