Abstract: In some embodiments, an apparatus is configured to wirelessly communicate with a base station 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, use a second, different retransmission parameter in a second frame transmission scheme for subsequent communications. In some embodiments, the retransmission parameter is a number of retransmissions or a number of hybrid automatic repeat request (HARQ) processes.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to selectively perform neighbor base station measurement. The UE may receive a neighbor base station list from the serving base station. The UE may categorize the neighbor base stations of the neighbor base station list into one of a plurality of measurement categories. The UE may be configured to perform measurements of neighbor base stations in respective categories at different rates.

Abstract: This disclosure relates to techniques for supporting narrowband device-to-device wireless communication, including possible techniques for performing discovery in an off grid radio system. According to some embodiments, a wireless device may determine a number of synchronization signal repetitions to use for a narrowband device-to-device transmission. The wireless device may perform the transmission, including transmitting the determined number of synchronization signal repetitions. The transmission may include an indication of the number of synchronization signal repetitions used in the transmission.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment (UE) device to adaptively enhance the quality of service (QoS) configuration of a bearer of communications conducted over a cellular network between a UE application and a server. The UE may use various information, including a QoS profile associated with the application, to determine requested QoS parameters and/or whether the UE is permitted to request or access enhanced QoS functionality. The UE may then send a request to the cellular network indicating the requested QoS parameters, and the network may adjust the QoS configuration of the bearer in response. The UE and the network may perform routine QoS measurements and exchange information in order to adaptively maintain and optimize the QoS configuration. These techniques may tend to provide more appropriate QoS to the application, which may improve user experience.

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: 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.

Abstract: This disclosure relates to techniques for efficient idle mode wakeup for wireless devices supporting an enhanced coverage mode and a normal coverage mode in a wireless communication system. A wireless device may camp on a cellular base station in idle mode. The wireless device may monitor a control channel associated with the normal coverage mode during a paging occasion. The wireless device may also monitor a control channel associated with the enhanced coverage mode during the paging occasion if a paging indication is not successfully decoded on the control channel associated with the normal coverage mode.

Abstract: An accessory wireless device partakes in a data session with a remote device. The data session may be a voice call or other service. To preserve the battery power of the accessory wireless device, the accessory wireless device opportunistically offloads medium-to-long range radio transmission and reception tasks to the companion wireless device while maintaining call continuity. The accessory wireless device and the companion wireless device communicate through a local connection. In one embodiment, the accessory wireless device pushes a wireless wide area network (WWAN) connection to the companion device by sharing selected security and network information with the companion wireless device. When the accessory device and/or the companion device determine that the local connection may not be sustainable, the accessory device pulls the WWAN connection of the companion device back to itself.

Abstract: This disclosure relates to techniques for supporting message mapping via time and/or frequency indexing. For example, these techniques may be applied to device-to-device wireless communication. For example, device to device discovery may use message mapping via frequency indexing. A portion of the payload of a message, such as a discovery message, may be offloaded to a frequency and/or time index. A receiving device may determine the offloaded portion of the payload based on the frequency and/or time (e.g., subcarrier and/or slot) used to transmit the message.

Abstract: A user equipment (UE) and base station may 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.
