Abstract:
Certain aspects of the present disclosure relate to techniques and apparatus for optimizing long term evolution (LTE) connected discontinuous reception (CDRX) for single radio hybrid tune away devices. Certain aspects provide a method for wireless communications by a user equipment (UE). The method generally includes entering a DRX mode wherein the UE alternates between an activity period and an inactivity period while connected to a first radio access technology (RAT) network, tuning away from the first RAT network for a tune away period to monitor signals in a second RAT network, determining when an inactivity timer for the DRX mode expires or will expire, and adjusting a value of the inactivity timer based, at least in part, on the determination.
Abstract:
A method for antenna switching is described. The method includes transmitting using a first antenna. The method also includes determining that a trigger occurs to switch to transmitting using a second antenna. The trigger is based on a combination of a physical uplink shared channel (PUSCH) maximum transmit power level (MTPL) counter and a physical uplink control channel (PUCCH) MTPL counter. The method further includes switching to transmitting using the second antenna based on the determination.

Abstract:
Aspects described herein relate to communicating in a wireless network. Downlink control information having a dynamic resource allocation indicator can be received from a serving access point. It can be determined whether the dynamic resource allocation indicator indicates at least one symbol in a subframe is for uplink data communications or reference signal transmission. Uplink data communications can be transmitted using the at least one symbol based at least in part on the determination that the dynamic resource allocation indicator indicates the at least one symbol in the subframe is for the uplink data communication, though a broadcasted reference signal configuration may indicate otherwise. Numerous other aspects are provided.
Abstract:
Various embodiments implemented on a mobile communication device (e.g., a multi-SIM-multi-active communication device) mitigate degraded transmit performance typically experienced by a lower-priority subscription during a Tx collision event in which a higher-priority subscription receives a shared Tx resource of the mobile communication device to the exclusion of the lower-priority subscription. Specifically, in various embodiments, a processor of the mobile communication device may determine when an upcoming transmission of the lower-priority subscription will collide with a scheduled transmission of the higher-priority subscription (i.e., may determine when a Tx collision event will occur between the subscriptions) and may implement one or more Tx collision management strategies in response to determining that the lower-priority subscription's upcoming transmission will collide with a transmission of the higher-priority subscription, thus improving the lower-priority subscription's overall performance.

Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided in connection with controlling a flow of data in a user equipment (UE). In one example, a communications device is equipped to monitor at least one parameter related to processing of data at the UE, detect that the at least one parameter has passed a threshold, and autonomously trigger a discontinuous reception (DRX) mode of operation for the UE. In an aspect, the at least one parameter may include, but is not limited to, a data rate, Central Processing Unit (CPU) utilization, memory utilization, component temperature, etc. within the UE.
Abstract:
Methods, systems, and devices are described for transmitting scheduling requests for uplink transmission resources following a handover. A user equipment (UE) may determine that a handover from a first base station to a second base station has occurred, and may implement one or more processes to enhance efficiency in communications following the handover. A UE, for example, may wait for successful acquisition and/or derivation of timing information from a base station before attempting to schedule uplink resources with the base station.

Abstract:
A method for wireless communication is disclosed. A time alignment timer is started. It is determined when the time alignment timer will expire. A time alignment request subframe that is prior to the time alignment timer expiring is identified. Uplink time alignment is requested in the time alignment request subframe.
