Claim:
1. A method for operating a wireless user equipment (UE) device according to idle-mode discontinuous reception (DRX) in a time-division multiple access (TDMA) cellular communication system, the method comprising: operating alternately in active and inactive states in a periodic manner according to DRX cycle timing for each of a plurality of DRX cycles; checking for paging messages while in the active state during each DRX cycle; decoding a paging message received while in the active state during at least one DRX cycle, wherein said decoding utilizes a joint detection technique for multiple access interference (MAI) cancellation; adaptively determining whether or not to perform cell measurements on each of a plurality of neighboring cells while in the active state during at least a subset of the plurality of DRX cycles, wherein said adaptively determining is based at least in part on cell characteristics of neighboring cells determined by utilizing the joint detection technique to decode paging messages; and wherein during the active state of at least one DRX cycle, said adaptively determining is based on cell characteristics determined by utilizing the joint detection technique to decode a paging message received during the same DRX cycle; performing neighboring cell measurements while in the active state during at least a subset of the plurality of DRX cycles, wherein the neighboring cell measurements are performed based on adaptively determining whether or not to perform cell measurements on each of the plurality of neighboring cells.
