Abstract: Device-to-device operations are scheduled based on receive and transmit pools that may have a conflict in time domain. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for resolving time domain conflict in device-to-device communication are provided. The apparatus may compute a first block rate metric for a first device-to-device communication on a first frequency and a second block rate metric for a second device-to-device communication on a second frequency. The apparatus may detect a time-domain conflict between the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency. The apparatus may prioritize the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency based on the first block rate metric and the second block rate metric.

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 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: A method for selectively prioritizing eMBMS includes: determining a collision metric associated with at least one of a plurality of eMBMS data streams on the first subscription; identifying a first eMBMS data stream of the plurality of eMBMS data streams having a highest collision metric amongst the plurality of eMBMS data streams on the first subscription; assigning the first eMBMS data stream with a higher QoS priority than a QoS priority assigned to paging occasions on the second subscription; and in response to detecting that an upcoming paging occasion on the second subscription coincides with an upcoming eMBMS data burst associated with the first eMBMS data stream on the first subscription, utilizing the RF chain to receive the eMBMS data burst on the first subscription based on the first eMBMS data stream on the first subscription having a higher QoS priority than the paging occasions on the second subscription.

Abstract: A mobile device determines that a primary cell (PCell) and a secondary cell (SCell) belong to a same multicast-broadcast single frequency network (MBSFN) area or that the PCell and the SCell can broadcast the same service. The mobile device determines a communication state of the SCell. If the SCell is active, the mobile device compares signal quality on the PCell and the SCell and selects to decode broadcast content on the PCell or the SCell. If the communication state indicating the SCell is deactivated or released, the mobile device switches to decode the broadcast content on the PCell. If the SCell is released and if the mobile device determines that the PCell is also released, then the mobile device switches to decode the broadcast content on the PCell and initiates a neighbor cell search.

Abstract: Techniques for optimized HARQ recombining are provided. In one exemplary embodiment, a method for wireless communication comprises receiving a broadcast message to determine a timing of a transmission window, receiving at least one transmission within the transmission window, and determining whether the at least one transmission is successfully decoded. The method further comprises instructing a lower protocol layer to ignore remaining transmissions within the transmission window upon a determination that the at least one transmission is successfully decoded, wherein the remaining transmissions and the at least one transmission comprise duplicate copies of a message segment.

Abstract: A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) in a distributed cellular vehicle-to-everything environment are disclosed to determine a schedule for transmissions on subchannels of multiple frequencies based on a set of UE-specific, dynamic, and performance related metrics or criteria. The metrics may include an estimated number of users on a subchannel, a best-bandwidth fit, channel loading conditions, transmission range, and quality requirements of an application, among others. Such a schedule for transmissions on subchannels of multiple frequencies may result in either an improved capacity utilization, an improved communication quality, or both.
