Abstract: A user equipment device (UE) may transmit, in a packet to a base station, information associated with resource configuration/resource requirement corresponding to wireless uplink communications of the wireless communication device. The base station may assign resources to the UE based on the received information. The UE may receive an uplink grant from the base station, with the uplink grant specifying resources for use by the wireless communication device during the uplink communications based on the information previously transmitted to the base station by the wireless communication device. The UE may send the packet at the time a voice call with the UE is initiated, and/or the UE may transmit the information during voice calls in response the UE changing one or more resource configuration parameters during the voice call. The UE may use Robust Header Compression packets of various types to transmit the resource configuration information.

Abstract: Apparatuses, systems, and methods for a wireless device to perform simultaneous uplink activity for multiple RATs in the same carrier using multiplexing at a layer above the physical layer. The wireless device may establish wireless links with first and second base stations, respectively, according to first and second radio access technologies (RATs), respectively. The first base station may provide a first cell operating in a first system bandwidth and the second base station may provide a second cell operating in a second system bandwidth. The wireless device may determine whether inter-RAT uplink coexistence in the same frequency band is enabled. If so, the wireless device may perform uplink activity for both the first RAT and the second RAT in the first system bandwidth by multiplexing uplink data for the first RAT and uplink data for the second RAT at a layer above the physical layer.

Abstract: In some embodiments, an apparatus is configured to wirelessly communicate with a base station in a real-time internet protocol (IP) session using a first retransmission parameter in a first frame transmission scheme. In some embodiments, the apparatus is configured to determine a current performance metric and, based on the current performance metric, negotiate to use a second, different retransmission parameter in a second frame transmission scheme for communications via the real-time IP session. In some embodiments, the retransmission parameter is a number of retransmissions or a number of hybrid automatic repeat request (HARQ) processes.

Abstract: This disclosure relates to techniques for handling voice and data under uplink limited conditions in a wireless communication system. A wireless device and a base station may establish a wireless communication link. Transmission time interval bundling (TTI-B) may be enabled for uplink communications between the wireless device and the base station. It may be determined that the wireless device is experiencing uplink limited conditions. One or more rules prioritizing a first type of data over a second type of data for uplink communications may be enabled based on TTI-B being enabled and the wireless device experiencing uplink limited conditions.

Abstract: Techniques are disclosed relating to wireless transmission energy budgets. In some embodiments, an apparatus is configured to determine wireless transmission energy budget for a plurality of time periods. In some embodiments, the apparatus determines budget differently depending on whether it is in a thermal mode or a peak power mode. In some embodiments, the apparatus blanks scheduled wireless transmissions that intersect with the battery signal. In some embodiments, for a time interval subsequent to assertion of the battery signal, the apparatus operates in the peak power mode and determines energy budget for periods based on an amount of energy used for wireless transmissions in a most recent period in which transmissions were blanked in response to the battery signal. In some embodiments, in the thermal mode, the energy budget is based on thermal information for the apparatus, but may also allow carryover of unused budget from previous periods.

Abstract: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.

Abstract: This disclosure relates to techniques for dynamically changing coverage modes and/or communication bandwidth in a wireless communication system. According to some embodiments, a wireless device may attach to a serving cell associated with a cellular network. A volume of data for upcoming communication with the cellular network may be determined. An indication of a requested communication bandwidth may be provided to the serving cell. The wireless device may communicate data with the serving cell using the requested communication bandwidth. In some instances, a request for narrowband communication bandwidth may result in use of a coverage enhancement mode, while a request for wideband communication bandwidth may result in use of a normal coverage mode.
