  • Patent number: 10172113
    Abstract: Transfer of Multimedia Broadcast/Multicast Services (MBMS) over a Single Frequency Network (MBSFN) service and idle mode unicast service for a mobile entity from a source base station to a target base station may be managed by a base station or mobile entity of a cellular wireless communications system (WCS). Operations related to the transfer may include obtaining an MBMS status of the mobile entity, and/or obtaining MBMS support information for the base station. A network entity may facilitate MBMS discovery by a mobile entity, by transmitting a data element to the mobile entity including service identifiers mapped to corresponding cell identifiers to indicate respective MBMS services to be broadcast in an WCS area on adjacent cells identified by respective ones of the cell identifiers. The MBMS services may be broadcast within the WCS area using the adjacent cells previously indicated in the data element.

  • Publication number: 20180338332
    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for transitioning between short DRX and long DRX cycles based on service type to improve performance (e.g., reduce delay) while limiting power consumption. In one example, the UE switches to a long DRX cycle after a DRX Short Cycle Timer, or drxShortCycleTimer, expires. The UE may also switch to a long DRX if the UE receives long DRX MAC control element (CE) from a gNB. In another example, a gNB may configure a radio bearer from a set of radio bearers (data radio bearer (DRB) and/or signal radio bearer (SRB)), denoted by S, to trigger the UE to enter a short DRX cycle.

  • Patent number: 10084567
    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.

  • Patent number: 9999024
    Abstract: Embodiments include methods implemented by a processor of a mobile communication device for managing tune-aways by a radio frequency resource supporting a first subscription to support a second subscription. The processor may determine a data loss ratio of the data of a media file that is lost in transmission to the mobile communication device. The processor may compare the data loss ratio of the data to a first data loss ratio threshold and a second data loss ratio threshold, and the processor may block a tune-away event of the radio frequency resource from the first subscription to the second subscription in response to determining that the data loss ratio of the data is greater than the first data loss ratio threshold and less than the second data loss ratio threshold.

  • Publication number: 20180145839
    Abstract: Methods, systems, and devices for wireless communication are described. Data for a broadcast or multicast service may be sent over a control channel. A network device may broadcast a message to indicate a plurality of enhanced multimedia broadcast multicast service (eMBMS) services offered by the network. The mobile device may transmit an indication to the network device identifying an eMBMS service of interest. The network device may transmit a configuration message before broadcasting or multicasting data of the eMBMS service of interest. The configuration message may notify the mobile device of a control channel on which to receive the data related to the eMBMS service. The network device may then broadcast or multicast the eMBMS service data on the control channel. The data may be segmented at a particular protocol layer and mapped to several transmission time intervals within each repetition of the control channel.

    Abstract: Various embodiments include a device processor that may monitor a data loss from a broadcast data stream received by a radio frequency (RF) resource of a multi-subscription multi-standby (MSMS) communication device using a first subscription. In response to determining that an amount of the monitored data loss plus an amount of expected data loss from anticipated tune-aways to a second subscription and a third subscription does not meet a first data loss threshold, the device processor may determine whether an amount of the monitored data loss plus an amount of expected data loss from an anticipated tune-away to a third subscription meets a second data loss threshold. The device processor may prevent the tune-away to the third subscription in response to determining that the amount of the monitored data loss plus the expected data loss from the anticipated tune-away to the third subscription meets the second data loss threshold.
