摘要： Apparatuses, systems, and methods for a wireless device to perform methods for determining resources for scheduling side-link communications. The resources may be semi-persistent and/or dynamic resources. A user equipment device (UE) may determine a resource map for use in scheduling semi-persistent resources for side-link communications with at least one wireless node. The UE may transmit a resource map request message indicating preferred resource blocks, where each resource block may be defined by a time and a frequency. The UE may receive a confirmation message that may include a report regarding a set of resource blocks. The set of resource blocks may be from the preferred resource blocks included in the resource map request message. The UE may determine, based, at least in part, on the confirmation message, resource blocks to be used for the side-link communications and initiate the side-link communications using the determined resource blocks.

摘要： 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.

摘要： A system, apparatus and method to maintain continuity of a Voice over Long Term Evolution (LTE) (VoLTE) call. The system includes a first user equipment (UE) configured to perform a (VoLTE) call and a second UE configured to perform the VoLTE call with the first UE. The UE's are configured to maintain continuity of the VoLTE call by determining when one of a first dedicated bearer linked to a first default bearer of the first UE or a second dedicated bearer linked to a second default bearer of the second UE is lost and transmitting a signal to an Internet Protocol (IP) Multimedia Subsystem (IMS) server that prevents release of the determined dedicated bearer, the signal further triggering a re-activation of the determined dedicated bearer.

摘要： 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.

摘要： This disclosure relates to management of a secondary component carrier by a wireless device when using carrier aggregation. According to one embodiment, a primary component carrier for communication between a base station and a wireless device may be configured according to a first wireless communication technology. A secondary component carrier may also be configured. The wireless device may detect a trigger condition to deactivate the secondary component carrier. In response, the wireless device may modify its feedback to the base station with respect to channel conditions for the secondary component carrier to cause the base station to deactivate the secondary component carrier.

摘要： Embodiments are presented herein for adjusting the conduct of routine communications of safety messages in V2X networks in order to conserve resources in participating power-limited devices while satisfying V2X system latency demands. Scheduling (e.g., timing and/or frequency) of safety message communications performed by certain UE devices participating in a V2X network may be dynamically adjusted according to various criteria, such as factors relating to the DRX cycle schedule, motion or mobility, traffic environment, and/or battery or power capabilities of the UE devices, which may conserve UE resources and power consumption. Certain UE devices may efficiently transmit safety messages to the V2X network using one of several proposed RACH-based procedures. In some embodiments, the size of safety message communications may be reduced through various compression techniques, and/or by reducing the amount of contained information, e.g., by omitting certain parameters, which may reduce the resources consumed by performing safety message communications.
