Adaptive Neighboring Cell Measurement Scaling for Wireless Devices

摘要

Adaptive neighboring cell measurement scaling by a wireless user equipment (UE) device. The UE may operate alternately in active and inactive states in a periodic manner according to DRX cycle timing for each of a plurality of DRX cycles. Paging messages may be checked for while in the active state during each DRX cycle. If a paging message is received, it may be decoded using a joint detection technique. The UE may adaptively determine whether or not to perform neighboring cell measurements during at least a subset of the DRX cycles, and perform neighboring cell measurements according to the adaptive determination. The adaptive determination may be based on one or more of joint detection of paging messages, one or more previous cell measurements, or an amount of motion of the UE.

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 determined by utilizing the joint detection technique to decode paging messages; and 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.
