Abstract: Aspects of the disclosure are directed to a method, apparatus, and computer software for wireless communication. In various examples, a method of wireless communication performed by a user equipment (UE) includes measuring channel quality over a measurement period associated with a voice call corresponding to a first subscription supported by the user equipment, determining whether the channel quality is sufficient to enable an adaptive multi-rate (AMR) decoder to ignore one or more bursts of a plurality of bursts carrying a block of data received at the user equipment, and causing the adaptive multi-rate decoder to decode the block of data without the one or more bursts when the channel quality is determined to be sufficient to enable the adaptive multi-rate decoder to ignore the one or more bursts. The channel quality may be measured by measuring a bit error rate for a transmission on a slow associated control channel (SACCH).

Abstract: Various embodiments implemented on a multi-subscription-capable communication device (e.g., a mobile communication device capable of supporting more than one wireless subscription) enable a data connection for a blanked subscription to be kept alive during transmit (Tx) blanking by ensuring at least one Packet Data Traffic Channel (PDTCH) transmission is sent to the network before the network's counter for PDTCH transmissions expires.

Abstract: A method for cell selection or cell re-selection by a wireless communication device in a Global System for Mobile Communications (GSM) network is described. The method includes obtaining signal-to-noise ratios (SNRs) associated with multiple cells. The method also includes delaying a camping decision until a broadcast control channel (BCCH) of a strong SNR cell is decoded. The SNR of the strong SNR cell is greater than the SNR of a high received signal strength indication (RSSI) cell. The method further includes camping on the strong SNR cell.

Abstract: Systems and methods for antenna selection in a wireless terminal with two radios are provided. Signals received using first and second antennas are demodulated by first and second modems according to first and second protocols. A receive path between the second antenna and the second modem can be controlled to receive signals according to the first protocol. A performance measure of demodulating, according to the first protocol, a signal received using the second antenna is determined. The performance measure may be determined using a mirror module in the second modem or using a search module in the first modem. The wireless terminal switches antennas so that the first modem demodulates a signal received using the second antenna, if the performance measure for using the second antenna is such that the switch would improve performance of the first modem.

Abstract: Systems and methods for antenna switching without using a radio-frequency switch are provided. A signal received via a first antenna is digitized to form a first digital received signal. A signal received via a second antenna is digitized to form a second digital received signal. A switch selects the first digital received signal or the second digital received signal to be supplied to a modem to be demodulated. The switch may also supply a digital transmit signal from the modem to be supplied to digital-to-analog converters to and then transmitted using the first or second antenna. Additionally, when the modem is demodulating the signal received via the first antenna, another modem may be demodulating the signal received via the second antenna and vice versa.
