Abstract: Aspects of the disclosure provide a method for reducing power consumption of a wireless communication device. The method can include receiving a discontinuous reception (DRX) configuration specifying a DRX having a DRX cycle, receiving an original scheduling request (SR) configuration specifying an original SR period, selecting an extended SR period according to the DRX cycle, the extended SR period being a multiple of the original SR period and corresponding to a set of candidate SR offsets, determining for each of the set of candidate SR offsets an overlap between active times caused by the DRX and active times caused by SR transmissions corresponding to the extended SR period, and selecting one of the set of the candidate SR offsets having a largest overlap to determine a period-extended SR configuration including the selected extended SR period and the selected SR offset.

Abstract: A communications apparatus includes a receiver and a processor. The receiver is configured to receive wireless signals. The wireless signals include a plurality of packets. The processor is coupled to the receiver and includes a first logic configured to perform operations of a first protocol layer and a second logic configured to perform operations of a second protocol layer higher than the first protocol layer. The operations of the first protocol layer includes: starting a timer in response to receiving a first packet with a first count value that is different from a deliver count value; and delivering a second packet with a second count value that is different from the deliver count value to the second logic before the timer expires.

Abstract: A wireless communication method and device are provided. The wireless communication method includes the steps of activating a power-saving mechanism by user equipment (UE) to stop monitoring a Physical Downlink Control Channel (PDCCH) when a network does not enable a Discontinuous Reception (DRX) mechanism to configure the UE to switch to a DRX mode or when the network disables the DRX mechanism.

Abstract: Various solutions for maintaining a radio resource control (RRC) connection with respect to user equipment and network apparatus in mobile communications are described. An apparatus may establish an RRC connection with a network node. The apparatus may transmit a layer 2 packet to maintain the RRC connection after a period of time without data transmission. The apparatus may transmit uplink data via the RRC connection without re-establishing the RRC connection.
