Abstract: Reducing power consumption for cellular broadcast communication by a wireless device. A cellular communication channel for cellular broadcast messages may be monitored in a discontinuous manner according to specified cellular broadcast scheduling periods. Between each pair of cellular broadcast scheduling periods, the wireless device may operate in a reduced power state. During each cellular broadcast scheduling period, at least a cellular broadcast scheduling message may be received. If all scheduled cellular broadcast messages are received prior to an end of a cellular broadcast scheduling period, the wireless device may operate in the reduced power state for the remainder of that cellular broadcast scheduling period after all scheduled cellular broadcast messages are received.

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: A user equipment (UE) and network entity implement improved communication methods which enable a UE to operate using differing modes of operation without detaching from a network. The UE may send first information indicating its capabilities to the network entity and may receive a first indication based on the first information. The first indication may indicate that the UE operate according to a first mode of operation. The UE may receive a second indication based on an occurrence of a first condition detectable at the network entity. The second indication may indicate that the UE operate according to a second mode of operation different from the first mode of operation. The first condition may be an initialization of a real time data packet session for the UE or may be a first message sent by the UE in response to one or more radio conditions exceeding a threshold.

Abstract: Techniques are disclosed relating to broadcasting and receiving system information in a radio access network (RAN). In some embodiment, a base station is configured to broadcast different sets of first system information blocks (SIBs) for different classes of user equipment devices (e.g., traditional UEs and UEs having a limited link budget). Different classes of UEs may use the different sets of SIBs to initiate communications with the base station.

Abstract: This disclosure relates to techniques for adaptive C-DRX Management. A wireless device and a cellular base station may establish a cellular link. According to some embodiments, the base station may monitor upcoming traffic with the wireless device. Based at least in part on the upcoming traffic for the wireless device, the base station may provide a command indicating to the wireless device to enter C-DRX. The command may further indicate to the wireless device a number of C-DRX cycles through which to remain in a low power state.

Abstract: Techniques are disclosed relating to broadcasting and receiving system information in a radio access network (RAN). In one embodiment, a base station includes at least one antenna, at least one radio, configured to perform cellular communication using a radio access technology (RAT), and one or more processors coupled to the radio. In this embodiment, the base station is configured to broadcast first system information blocks (SIBs) encoded using a first coding rate and a first identifier. In this embodiment, the base station is also configured to broadcast second SIBs encoded using a second coding rate that is lower than the first coding rate and a second identifier. In this embodiment, the second SIBs include only a portion of the information included in the first SIBs and the second SIBs are usable by user equipment devices (UEs) having a limited link budget to determine access parameters for the base station.
