Abstract: Certain aspects of the present disclosure provide methods and apparatus for excluding a measurement gap duration from an inactivity timer period. An example method generally includes maintaining an inactivity timer used to track a number of time intervals during which no downlink transmission is received by the UE; and excluding time intervals occurring during a measurement gap when updating the inactivity timer.

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: Certain aspects of the present disclosure relate to techniques and apparatus for a user equipment (UE) to delay RLC retransmissions (e.g., during off-durations, including CDRX off-durations). According to aspects of the present disclosure, a UE may delay triggering an RLC retransmission of an RLC PDU until after a next opportunity for the UE to receive an RLC ACK of the RLC PDU. By delaying RLC retransmissions, a UE may be prevented from waking up from one or more CDRX off-durations and using power associated with waking up from the one or more CDRX off-durations.

Abstract: Certain aspects of the present disclosure provide methods for adapting one or more parameters for uplink transmissions based on a channel condition profile. An example method generally includes obtaining, from a base station, feedback relating to one or more uplink transmissions sent from the UE to a base station (BS); generating, based on the feedback, a channel condition profile of one or more channels associated with the one or more uplink transmissions; and taking one or more actions, based on the channel condition profile, to adjust at least one of a power, code rate, or modulation scheme for one or more subsequent uplink transmissions.

Abstract: Certain aspects of the present disclosure provide techniques for defending against false semi-persistent scheduling (SPS) activation detection and/or missed SPS release. According to certain aspects, a user equipment (UE) may detect one or more conditions for a semi-persistent scheduling (SPS) activation or release are met based on a downlink transmission, generate one or more metrics related to downlink transmission, and determine a valid SPS activation or release has occurred if the one or more metrics satisfy one or more criteria. According to certain aspects, a UE may determine a valid semi-persistent scheduling (SPS) activation has occurred, detect a number of PDSCH CRC failures, and implicitly declare an SPS release based on the detection.

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.

According to certain aspects, a method for wireless communications is provided. The method generally includes performing communications with a base station (BS) using radio components tuned to a first air interface, detecting a tune-away of the radio components from the first air interface to a second air interface while performing the communications, and scheduling one or more packets for retransmission to the BS upon completion of the tune-away, wherein the one or more packets are one or more packets that failed to be transmitted due to the tune-away.
