Abstract: A device, system, and method uses a camp only mode based on a connectivity status. The method is performed at a device that is configured to establish a first connection to a first network and configured to establish a second connection to a second network. The method includes determining the connectivity status of the device. When the connectivity status indicates that the device has established the first connection, the method includes utilizing a camp-only mode to monitor the second network, the camp-only mode reducing a frequency of at least one type of operation associated with the second network, the camp-only mode configured to retain a capability of determining whether an emergency message is being broadcast over the second network.

Abstract: Various radio resource management techniques may be implemented to reduce in-device coexistence issues and/or interference between a Uu link established between a mobile device (first UE) and a base station (first NB), and a sidelink/PC5 link established between the first UE and another mobile device (second UE), where the second UE is served by a different base station (second NB). The first UE may receive, from the first NB, measurement configuration information that enables/configures the first UE to report to the NB any indication(s) of issues caused by communications between the first UE and the second UE over the PC5 link affecting communications between the first UE and the first NB over the Uu link, and/or communications over the Uu link affecting communications over the PC5 link. The first NB may analyze the feedback from the first UE and may implement mitigation measures to reduce/eliminate any interference and/or in-device-coexistence issues.

Abstract: Techniques are disclosed relating to apportioning data between network links in dual-connectivity environments. In some embodiments, a packet data convergence protocol (PDCP) entity implemented by a mobile device determines a ratio for sending packet data to two or more different radio link control (RLC) entities implemented by the mobile device for dual connectivity communications via two or more different networks. In some embodiments, in response to a current data volume meeting a threshold value, the PDCP entity apportions packet data between the two or more different RLC entities based on the determined ratio. The ratio may be determined based on various input parameters from one or more protocol layers or may be specified by the network. In various embodiments, the disclosed techniques may improve resource utilization and reduce re-ordering delay at the receiver.

Abstract: An accessory device may establish a short range link to a companion device, and the accessory device may use the companion device as a proxy to conduct a data session over a cellular network. Based on a latency requirement associated with the data session and/or a signal strength of the short range link, the accessory device may dynamically determine to transition its cellular radio from a powered-off mode to a low power mode.

Abstract: This disclosure relates to providing coexistence features for cellular communication in unlicensed spectrum. A wireless device may communicate with a cellular base station in accordance with an original communication configuration. The wireless device may determine that a communication activity is occurring at the wireless device that has a duration longer than a duration threshold. The wireless device may provide an indication to the cellular base station to modify the communication configuration with respect to operation in an unlicensed frequency band based at least in part on determining that a communication activity is occurring at the wireless device that has a duration longer than the duration threshold. The wireless device may communicate with the cellular base station in accordance with a modified communication configuration.

Abstract: This disclosure relates to broadcast information block assistance for a wireless device. The wireless device may obtain a first plurality of broadcast information blocks from a first base station. The wireless device may receive a second plurality of broadcast information blocks associated with the first base station from a source other than the first base station. The wireless device may determine if the second plurality of broadcast information blocks match the first plurality of broadcast information blocks based on version information specified in the first plurality of broadcast information blocks. When the broadcast information blocks match, the wireless device may use the first and second pluralities of broadcast information blocks to perform communication with the first base station without obtaining the second plurality of information blocks from the first base station.

Abstract: Systems, apparatus and methods enable layer 2 (L2) relaying optimizations for a remote user equipment (UE) to receive system information (SI) from a relay UE. The relay UE may establish a sidelink communication channel with the remote UE that is in a radio resource control (RRC) idle state, an RRC inactive state, or an out-of-coverage (OOC) state with respect to the base station. The relay UE decodes a relay SI request received through the sidelink communication channel from the first remote UE. The relay SI request indicates requested system information. The Relay UE obtains the requested system information or a subset of the requested system information from a memory device or from the base station and encodes a relay SI response to send to the first remote UE. The relay SI response includes the requested system information or the subset of the requested system information.
