Abstract: A UE may receive, via a first communication link that uses a first radio access technology (RAT), information that identifies a threshold associated with a second communication link that uses a second RAT. The UE may monitor one or more communications on the second communication link. The UE may determine whether a parameter associated with the second communication link satisfies the threshold based at least in part on monitoring the one or more communications on the second communication link. The UE may provide a message via the first communication link when the parameter associated with the second communication link satisfies the threshold.

Abstract: Early termination of enhanced multimedia broadcast-multicast service (eMBMS) is discussed. Forward error correction (FEC) redundancy data is added to broadcast data, such that if enough of the data symbols are successfully received, the data object may be reassembled before the entire transmission has been received. The aspects involve an application processor and modem processor, which may either be integrated into the same integrated circuit or separate components. The application processor obtains a total number of source symbols and a redundancy level for a data object to be received from the eMBMS, receives the successfully received data symbols from the modem processor, and then determines whether the number of successfully received data symbols exceeds a threshold for reassembling the transmitted data object. If so, then the application processor and/or the modem processor can shut down until the next broadcast.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. In a first configuration, the apparatus is an eNB. The eNB constructs an MCCH change notification, and sends the MCCH change notification with a carrier frequency index for a first frequency of a first cell on a second frequency of a second cell. In a second configuration, the apparatus is a UE. The UE receives a configuration with aggregated carriers including a primary carrier from a primary cell and one or more secondary carriers from one or more corresponding secondary cells, and receives an MCCH change notification with a carrier frequency index for a first frequency of a first cell on a second frequency of a second cell. The first cell and the second cell are each one of the primary cell and the secondary cells.

Abstract: Systems, methods, and devices of the various embodiments provide a multipath communication scheduler for an in-vehicle computing device, such as a vehicle's autonomous driving system, vehicle's telematics unit, vehicle's control system, etc. In various embodiments, a distributed leaky bucket based scheduler for an in-vehicle computing device may assign packets for transport to a plurality of modems based at least in part on the determined delivery delays. In various embodiments, delivery delays may be determined based on leaky bucket levels, burst sizes, delivery rates, and end to end delay estimates for each of the plurality of modems. In various embodiments, the scheduler may be one of a plurality of schedulers each associated with a separate stream of packets assigned to the plurality of modems and the leaky bucket levels may be determined on a per stream basis.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines a failure to receive an MSI for a first MSP. The UE attempts to decode one or more subframes in the first MSP. The UE detects an occurrence of an MSP abort decoding event. The UE determines that the first MSP does not include any subframe that carries MBMS data of an MBMS segment based on the detection of the MSP abort decoding events. The UE aborts the attempt to decode the one or more subframes.

Abstract: Techniques are described for wireless communication at a wireless communication device. One method includes receiving wireless wide area network (WWAN) packets at a WWAN processing subsystem of the wireless communication device; transferring wireless local area network (WLAN) packet information from a WLAN processing subsystem of the wireless communication device to the WWAN processing subsystem, the WLAN packet information comprising a subset of data associated with WLAN packets; performing a reordering process in the WWAN processing subsystem, the reordering process based at least in part on the received WWAN packets and the WLAN packets that correspond to the transferred WLAN packet information; and providing an indication of the reordered WWAN packets and the WLAN packets to an application processing subsystem of the wireless communication device.

Abstract: Embodiments include systems and methods for managing access to receive chains of a multi-subscription multi-standby (MSMS) communication device. A device processor may determining a receive mode of the MSMS communication device. In response to determining that the receive mode is a diversity sharing mode, the device processor may monitor a data loss from the broadcast data stream, and may determine a first subscription schedule and a second subscription schedule. The device processor may determine that the data loss is greater than or equal to a threshold, and the device processor may determine that there is an upcoming overlap between the first subscription schedule and the second subscription schedule. The device processor may prevent the second subscription from using the second receive chain.
