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: 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.
