Title:
LINK-QUALITY ESTIMATION METHOD AND COMPONENTS FOR MULTI-USER WIRELESS COMMUNICAITON SYSTEMS
Document Type and Number:
WIPO Patent Application WO2004070984
Kind Code:
A3
Abstract:
Received signal characteristics of multiple concurrently received channels are determined using an analytical approach for computation. A receiving wireless transmit receive unit and method are provided for processing concurrent communication signals from a plurality of transmitting WTRUs (50k) that concurrently transmit successive data blocks in a plurality of K forward channels. The receiving WTRU (70') preferably has a receiver (86) configured to receive successive data blocks of K concurrent transmissions transmitted from the transmitting WTRUs (50k) on the respective K forward channels. The processor (55k) is configured to successively compute instantaneous signal to interference ratio values for each forward channel j, for integers j=1 to K, based on a cross correlation matrix of channel response characteristics of K concurrently received data blocks and to selectively compute an average value that is used for the computing the individual channel characteristics for the forward channel K. The individual channel characteristics are advantageously used for power control or for the processing of the data blocks received on the respective forward channels.
