Abstract: Methods and devices are disclosed for enabling improved performance on a single-transmit multi-SIM wireless communication device. The wireless communication device may detect a voice communication on a modem stack associated with the first SIM and a data communication on a modem stack associated with the second SIM. The wireless communication device may identify a data rate used by the voice codec to encode uplink traffic channel (TCH) bursts in the voice communication, and determine whether the identified data rate used by the voice codec permits TCH burst cancellation. If it is determined that the identified data rate used by the voice codec permits TCH burst cancellation, the wireless communication device may downgrade a portion of the uplink TCH bursts scheduled on the modem stack associated with the first SIM.

Abstract: Methods and devices are disclosed for enabling improved transmission performance on a multi-SIM wireless communication device. The wireless device may detect a voice communication in a held state on a modem stack associated with the first SIM and an active voice communication on a modem stack associated with the second SIM. The wireless device may detect a conflict between at least one silence descriptor (SID) frame scheduled for transmission by the modem stack associated with the first SIM and a transmit opportunity for the modem stack associated with the second SIM. Once the wireless device identifies a SID frame transmission rate for the modem stack associated with the first SIM, the wireless device may apply a reduction scheme to the SID frames scheduled to be transmitted by the modem stack associated with the first SIM.

Abstract: Fast Associated Control Channel (FACCH) information is combined if a first block of FACCH information and a repeated block of FACCH information each fail a respective integrity check. An algorithm for realizing repeated FACCH diversity combining gains for different codec and discontinuous transmission (DTX) configurations is applicable to Full Rate codecs, Half Rate codecs, and discontinuous transmission scenarios. A pair of buffers may be used in a ping-pong fashion to store decoding soft or hard decisions for failed FACCH blocks.

Abstract: Access terminals are adapted to blacklist one or more neighboring cells from acquisition attempts. For instance, an access terminal may receive a transmission including a list of neighboring cells to be monitored while connected to a particular serving cell. The access terminal may determine that a predefined number of consecutive acquisition attempts with a particular neighboring cell have failed. In response to failure of the predefined number of consecutive acquisition attempts, the access terminal can blacklist the neighboring cell from subsequent acquisition attempts for a predefined blacklisting period. Following the duration of the blacklisting period, the access terminal may conduct a subsequent acquisition attempt with the neighboring cell. Other aspects, embodiments, and features are also claimed and described.

Abstract: Access terminals are adapted to facilitate data block decoding, where a header may be decoded while a data payload is not decoded. According to one example, an access terminal can convey information from an upper layer of a protocol stack to a physical layer of the protocol stack. The conveyed information can be adapted to cause the physical layer to bypass decoding a data payload for one or more received data blocks. On receipt of a data block, a header of the received data block can be decoded at the physical layer without decoding a data payload for the received data block. Other aspects, embodiments, and features are also included.
