Abstract: Performing concurrent data communication and voice call monitoring using a single cellular radio. According to some embodiments, the UE may perform data communication, via the radio, using a first RAT, supported by a first SIM. The UE may also perform paging functions for a voice communication, via the radio, using a second RAT, supported by a second SIM. In some scenarios, the first and second RATs are the same. The data communication and the paging functions may be performed concurrently using shared physical layer resources. For example, the shared physical layer resources may comprise a shared software defined radio (SDR) configured to demodulate and/or decode signals of the data communication and the paging function. As another example, the shared physical layer resources may comprise a shared Rake receiver configured to demodulate signals of the data communication and the paging function.

Abstract: This disclosure relates to techniques for estimating baseband power consumption and using the baseband power consumption estimation to select baseband operation features. According to some embodiments, one or more baseband power consumption modifiers occurring during an estimation window may be identified. Baseband power consumption of the wireless device during the estimation window may be estimated based on the identified baseband power consumption modifiers occurring during the estimation window. Baseband data throughput of the wireless device during the estimation window may also be estimated. One or more baseband operation characteristics may be selected based at least in part on the estimated baseband power consumption during the estimation window, possibly in conjunction with the estimated baseband data throughput during the estimation window, current wireless medium conditions, and/or other considerations.

Abstract: Providing adaptive channel state feedback (CSF) reports in discontinuous reception (DRX) scenarios in a power-efficient manner. The described algorithm may be able to make adaptive decisions to carry over the CSF from previous DRX cycles based on a comparison between an offset at which CSF values are stable and an offset at which a CSF report is to be sent to a base station. If the CSF values are not stable by the time the CSF report is to be sent, a CSF report from a prior DRX cycle may be used. Alternatively, if the CSF value are stable by the time the CSF report is to be sent, a determination may be made to either generate a new CSF report or use a prior CSF report. The latter determination may be made based on various criteria, including channel conditions and DRX cycle length.

Abstract: A method for determining whether an acknowledgement received by a user equipment from an external device is a forced acknowledgement. The method including transmitting a set of data stored in an uplink buffer to an external device, receiving an acknowledgement from the external device, determining if the acknowledgement received from the external device was a forced acknowledgement and flushing out an uplink buffer if determined that the acknowledgement was not a forced acknowledgement. The determining the acknowledgement is a forced acknowledgment being based on whether an uplink retransmission collides with one or more scheduled transmission times, a Physical Hybrid-ARQ Indicator Channel (PHICH) falls between gap measurements and an uplink retransmission collides with one of the gap measurements or a TTI bundling retransmission collides with a gap measurement. If the acknowledgement is not a forced acknowledgment, a set of data stored in the uplink buffer is retransmitted to the external device.

Abstract: Embodiments relate to a User Equipment (UE) device and associated method performing improved data roaming with reduced cost. The UE may comprise at least one radio, one or more processors, a first SIM entity and a second SIM entity. The first SIM entity may be configured to implement subscriber identity module (SIM) functionality for a subscribed voice and/or data plan of a first carrier. The second SIM entity may be configured to facilitate dynamic subscription to a local data plan of a second carrier when the UE is data roaming outside of a network of the first carrier. As one example, the UE, using the second SIM entity, may be configured to dynamically subscribe to a pay-as-you-go data plan of a second carrier, to which the user is not subscribed, when the user is data roaming outside of the first carrier's network. This dynamic subscribing may operate to reduce cost to the user, since the local data plan of the second carrier likely has less expensive data rates than those available during normal data roaming.
