Abstract: Various embodiments include multi-subscription multi-standby (MSMS) communication devices and methods for managing a tune-away by a radio frequency (RF) resource supporting a first subscription to support a second subscription. A device processor may monitor a data loss during a first burst of a segment of a broadcast data stream received using the first subscription by the MSMS communication device. The device processor may calculate a permitted data loss of the segment of a broadcast data stream. The device processor may reserve one or more subframes in a second burst of the segment based on the permitted data loss, and the device processor may prevent a tune-away of the RF resource from the first subscription to the second subscription during the reserved one or more subframes of the second burst.

Abstract: Aspects of the present disclosure provide mechanisms for count synchronization in a wireless communication network. A respective count value may be maintained for each packet transmitted over a wireless connection, where each count value includes a respective hyper frame number and a respective sequence number. To synchronize a current count value associated with a current packet, a count synchronization may be initiated to transmit at least a current hyper frame number of the current count value over the wireless connection.

Abstract: Techniques are described for wireless communication. One method includes identifying a decoding status of one or more physical layer packets before inactivity on a secondary component carrier (SCC) in a shared radio frequency spectrum band; initiating an SCC reordering timer, wherein the SCC reordering timer is initiated when the decoding status of the one or more physical layer packets is identified as unsuccessful; and triggering a transmission, to a base station, of a radio link control (RLC) status report upon expiration of the SCC reordering timer. The RLC status report is transmitted before expiration of a RLC reordering timer initiated when the decoding status of the one or more physical layer packets is identified as unsuccessful. In some examples, the method may include resetting the SCC reordering timer when one or more additional physical layer packets are received on the SCC.

Abstract: Methods, systems, and devices are described for wireless communication at a user equipment (UE). In some examples, the UE may identify an initialization and refresh (IR) packet at the radio link control (RLC) layer based the size of the IR packet, where the IR packet comprises a larger ciphered PDU size than a compressed RoHC packet. Accordingly, once the UE identifies the received packet as an IR packet, the UE may attempt to decipher the IR packet using one or more HFN offset values. In one example, the UE may determine whether the IR packet is deciphered correctly based on cyclic redundancy check (CRC) value of the deciphered IR packet. As a result, the present disclosure allows the UE to re-synchronize with the transmitting device by at least one of incrementing or decrementing an HFN value at the receiving device.

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: Methods, systems, and devices are described for wireless communication. A user equipment (UE), for example, may determine a content size of an uncompressed buffer and a content size of a compressed buffer. The UE may then generate a buffer status report (BSR) based on the content sizes of the uncompressed buffer and the compressed buffer. Alternatively, a base station may receive a BSR based on a size of an uncompressed buffer of the UE. The base station may then receive a compressed packet from the UE and may determine a compression gain based on a size of the compressed packet and a size of a corresponding uncompressed packet. The base station may then adjust the received BSR based on the compression gain.

Abstract: Methods, systems, and devices are described for wireless communication at a device. A transmitting device such as a base station may select some packets for direct transmission to a receiving device using data compression based on the reliability of the direct connection. The transmitting device may select other packets for indirect transmission via an unreliable connection using uncompressed packets or compressed packets that will not be used to update a compression buffer. In some cases, uncompressed packets may also be sent via the reliable connection. If a packet sent over the unreliable connection is lost, it may be transmitted over the reliable connection.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for managing scheduling requests (SRs) in a user equipment (UE) that supports a split data radio bearer (DRB). In some aspects, the UE may trigger a first SR for a first communication link and a second SR for a second communication link in response to determining that a first amount of data in the UE data buffer is greater than a first threshold. The UE may transmit the first SR to a first base station (BS) via the first communication link. Prior to transmission of the second SR, the UE may determine whether a second amount of data in the UE data buffer is less than a second threshold. The UE may cancel the second SR in response to the second amount of data in the UE data buffer being less than the second threshold.
