Patent ID: 8498244

Claim:
A method for enabling a mobile station to report channel quality in a wireless communication system, the method comprising: receiving, from a base station, a packet downlink assignment message for requesting to report channel quality parameters, the packet downlink assignment message including a reduced transmission time interval (RTTI) assignment indicating a packet data channel (PDCH) pair including two consecutive timeslots in a time division multiple access (TDMA) frame; receiving a first radio block and a second radio block that are intended for the mobile station via the PDCH pair, the first radio block including four bursts transmitted through the PDCH pair in first 10 ms, the second radio block including four bursts transmitted through the PDCH pair in second 10 ms; determining the channel quality parameters for the PDCH pair over a filtering period, the filtering period being 20 ms; and reporting the channel quality parameters for the PDCH pair to the base station, wherein the channel quality parameters include a mean Bit Error Probability (MEAN_BEP) and a coefficient of variation of BEP (CV_BEP), wherein if the first radio block and the second radio block use same modulation scheme, the channel quality parameters for the PDCH pair are determined based on the first radio block and the second radio block, and wherein if the first radio block and the second radio block use different modulation schemes, the channel quality parameters for the PDCH pair are determined based on one of the first radio block and the second radio block.
