Abstract: The techniques described herein include provide solutions to optimizing the battery power of a user equipment (UE) though energy optimal radio link adaption. A UE may determine an energy optimal modulation and coding scheme (MCS). An energy optimal MCS may include an MCS that enables reception of a data payload at a lowest total energy consumed by a receiver. In some implementations, the MCS may be based on several factors, including time and/or data rate constraints and changes in transfer rates relative to changes in energy consumption. The UE may communicate the energy optimal MCS to a base station, and the base station may send a data payload to the UE using an energy optimal data transfer rate that is based on the energy optimal MCS.

Abstract: The techniques described herein include superior home-on-home roaming procedures by enabling user equipment (UE) to modify a home public land mobile network (HPLMN) search periodicity based on a likelihood of detecting an HPLMN cell (e.g., base station). A UE may be configured to determine a current geographic location of the UE, access a database that includes information about the HPLMN for the location (e.g., prior HPLMN searches), determine an appropriate HPLMN search periodicity based on the information, and perform HPLMN searches based on the appropriate HPLMN search periodicity. In some implementations, the UE may determine the HPLMN search periodicity based on a number (N) of HPLMN cells, and/or times an HPLMN cell sample, associated with the geographic area, has been detected previously.

Abstract: Techniques described herein include solutions for enabling user equipment (UEs) to report UE capability information based on deployed channel bandwidths (BWs) in each radio frequency (RF) band used by a base station. During an attached procedure, a base station may UE capability information from a UE and receive requested frequency band information (RFB) in response thereto. The RFB information (e.g., UE capability information) may be based on a comparison of an actual maximum BW for all possible CA combinations for the base station and ?—a maximum aggregate BW supported by the UE. The UE may report the RFB to the base station for the CA combinations with a maximum BW that is less than or equal to ?. After reporting, the UE may proceed with the attach procedure. Additional and alternative features and techniques are also described.

Abstract: Wireless devices, networks and methods may operate to have a wireless device cause a base station to trigger voice call continuity handovers responsive to the quality of the cellular radio link in addition to the base station triggering such handovers based on location or mobility. Furthermore, wireless communication devices may also perform monitoring of multiple buffers operating within the wireless communication device and associated with different respective communication layers, in addition to monitoring the quality of the cellular radio link, to perform intelligent dropping/discarding and/or scheduling of packets at the wireless communications device. Any one or more of these features may improve the ability of the wireless communications device to achieve stated Voice over Long Term Evolution (VoLTE) performance benchmarks in the context of the realities of current VoLTE networks.

Abstract: This disclosure relates to techniques for a link budget limited UE to improve communications performance with a cellular network. The UE may perform signal to interference noise ratio (SINR) measurements and use these measurements to adjust a received signal power value that is provided to the cellular network as a received signal power measurement. The UE may generate the received signal power value based at least in part on the SINR measurement in order to reduce the likelihood of handover when the UE has good SINR but poor received signal power. The UE may also provide preferred configuration information to the base station which enhances the performance of the UE when link budget limited. The configuration information may specify one or more parameter values designed to provide improved performance for a link budget limited device.

Abstract: In some embodiments, a wireless device such as a user equipment (UE) may communicate with a base station using an advanced form of carrier aggregation. The UE may provide signaling to the network specifying a number P of downlink component carriers to be configured for use by the UE for downlink carrier aggregation and a number Q of uplink component carriers to be configured for use by the UE for uplink carrier aggregation. The UE can only utilize a lesser number M of downlink component carriers at any given time in downlink carrier aggregation and can only utilize a lesser number N of uplink component carriers at any given time in uplink carrier aggregation. Thus the UE may request the network to configure a greater number P and Q of downlink and uplink component carriers, respectively, than the UE can actually use at any instant of time.
