Abstract

Discontinuous reception (DRX) operation may be utilized to maintain connection with user equipment (UE) by increasing the effective control channel transmission periodicity. UEs may be configured with a compatible control channel transmission periodicity such that multiple UEs may share a resource in a time-division-multiplexed manner using DRX offsets and periodicity, effectively extending control channel transmission periodicity through resource overloading.

Claims (49)
