Abstract: In some embodiments, a user equipment (UE) and base station implement improved communication methods which enable a UE to operate according to a sub-frame allocation based on its current power state. The UE may transmit information including a maximum number of uplink (UL) sub-frames the UE can transmit in an allocation period and receive, from a base station, a first sub-frame allocation based on at least the first information. In embodiments, the UE may merge an un-allocated UL sub-frame's downlink association set with a next closest allocated UL sub-frame's downlink association set.

Abstract: Operating a user equipment (UE) which comprises a first radio that is configured to operate according to a first radio access technology (RAT) and a second RAT. The UE may receive a request to perform a tune away operation for the second RAT while performing measurement for the first RAT (e.g., intra-cell measurement, inter-cell measurement, and/or inter-RAT measurement). Instead of waiting to complete the measurement of the first RAT, the UE may tune the radio to a frequency of the second RAT to perform the tune away operation (e.g., page decoding) for the second RAT. After completing the tune away operation of the second RAT, the UE may tune the radio back to a frequency corresponding to the first RAT in order to continue the measurement operations of the first RAT.

Abstract: Methods, apparatuses and computer readable media are described that manage transmit power levels for a wireless device connected to a network access system of a wireless network. Processing circuitry in the wireless device obtains a target average transmit power level. Based on estimates of an actual average transmit power level for a sliding window of a past time period and the target average transmit power level, the processing circuitry determines a target transmit power level, a duty cycle percentage, and a transmit pattern of transmit on frames and transmit off frames for a future time period. The processing circuitry sends to the access network system signaling messages indicating non-zero valued buffer status reports for the transmit on frames and zero valued buffer status reports for the transmit off frames. Non-zero values correspond to actual amounts of pending uplink data, while zero values are sent irrespective of actual uplink buffer status.

Abstract: Performing data communications by a Dual SIM Dual Active (DSDA) user equipment (UE), while simultaneously conducting two concurrent voice calls. The UE may receive a request to perform data communications while conducting a first voice call on a first radio and concurrently conducting a second voice call on a second radio. The UE may then determine whether one of the voice calls is currently on hold. The UE may perform the data communications using the radio on which the held call is being conducted. The UE may therefore dynamically select available slots from the first radio and the second radio for performing the data communication, based on which of the first radio and the second radio has a voice call that is currently on hold. In some embodiments, the data communications may be performed using a Long Term Evolution (LTE) protocol stack.
