    Abstract: Dynamic forward error correction (FEC) setting is discussed in which the network determines a FEC percentage for each video segment of a video streaming service, based on consideration of the transfer length of the video segment and the allocated bandwidth. When the transfer length and allocated bandwidth reflect transmission of less than peak bandwidth, the network will determine a higher FEC percentage that uses the otherwise wasted bandwidth to transmit additional redundancy symbols. The additional redundancy symbols increase the error recovery rate when collisions occur between streaming video reception and page monitoring occasions of other networks in multi-network, multi-subscriber identification module (SIM) mobile devices. A network entity may then transmit the dynamic FEC percentage for each video segment in the file description table (FDT) associated with the video streaming service.

    Abstract translation: 讨论了基于视频段的传输长度和分配的带宽的考虑，网络确定视频流服务的每个视频段的FEC百分比的动态前向纠错（FEC）设置。 当传输长度和分配的带宽反映小于峰值带宽的传输时，网络将确定使用否则浪费的带宽来传输附加冗余符号的较高FEC百分比。 当在多网络，多用户识别模块（SIM）移动设备中的流视频接收和其他网络的页面监视场合之间发生冲突时，额外的冗余符号增加了错误恢复速率。 然后，网络实体可以在与视频流服务相关联的文件描述表（FDT）中的每个视频段发送动态FEC百分比。

    Abstract: Aspects disclosed herein relate to utilizing and/or mitigating superfluous resource grants in a wireless network. In one aspect, an uplink resource grant is received from a network node, and a plurality of protocol data units are mapped from a buffer over the uplink resource grant in generating a transport block for transmitting data. It is determined that additional resources remain on the uplink resource grant after mapping the protocol data units, and one or more additional protocol data units are mapped for opportunistically transmitting data from a best effort buffer over the additional resources. In another aspect, a maximum grant size for a user equipment (UE) is computed based at least in part on a modulation and coding scheme and a number of resource blocks configured for the UE, and used along with a priority of a bearer to determine whether to send a buffer status report for the bearer.

    Abstract: Methods and apparatus are provided for quick recovery of missed packets after a user equipment (UE) tunes back to a first network after tuning away from the first network. The UE may determine that a trigger event has occurred, and in response to the determination, modify a negative acknowledgement (NACK) timing configuration from a default configuration. Modifying the NACK timing configuration may include using an aggressive NACK timing configuration for a configurable period of time, in response to detecting a trigger event. The trigger event may include detecting missed packets after a tune back, unavailability of sufficient memory to hold packets until a gap created by missed packets may be filled, or tuning back to a network.

    Abstract: Embodiments include methods to manage tune-away events on a multi-subscription multi-standby wireless communication device having an RF resource supporting a first subscription and a second subscription by changing an order of Multicast Traffic Channel (MTCH) transmissions across a number of Multicast Channel Scheduling Periods (MSPs). In various embodiments, the order of MTCH transmissions may be changed by rotating the Logical Channel Identifier (LCID) order in a Multicast Channel (MCH) Scheduling Information (MSI) Media Access Control (MAC) message sent from a serving base station or tower (e.g., a serving Evolved Node B (eNB)) to a multi-subscription multi-standby wireless communication device. In various embodiments, a multi-subscription, multi-standby wireless communication device may activate a MTCH for one or more service according to the dynamic MSI MAC message.
