Abstract: Various embodiments include multi-subscription multi-standby (MSMS) communication devices and methods for managing reception of data using a first subscription following a tune-away by a radio frequency (RF) resource chain from the first subscription to a second subscription. In various embodiments the MSMS communication device may receive data over the first subscription during a warm-up period of the RF resource chain following completion of the tune-away. In some embodiments, the device processor may receive the data over the first subscription during the warm-up period using one or more channel parameters of the first subscription determined before the tune-away. In some embodiments, the device processor may receive data over the first subscription during the warm-up period using one or more channel parameters of the first subscription determined initially during the warm-up period.

Abstract: This disclosure provides systems, methods, and apparatus for mobile transmit diversity. In one aspect a method of controlling a transmit power level of a wireless communications apparatus is provided. The method includes adjusting the transmit power level of a transmitter of the wireless communications apparatus to a first transmit power level in response to detecting a de-sense event indicative of interference with a signal received by a receiver of the wireless communications apparatus due to emissions from the transmitter. The method further includes maintaining the transmit power level substantially at the first transmit power level for a first time interval in response to adjusting the transmit power level to the first transmit power level. The method further includes adjusting a transmit power level limit of the transmitter after the time interval at a rate for a second time interval.

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: 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.
