Abstract: Aspects are presented herein of apparatuses, systems, and methods for secondary cell group (SCG) addition. A wireless device may establish communication with a first base station that is comprised a master cell group (MCG). The wireless device may receive signaling from the first base station configuring a second base station in a secondary cell group (SCG). The wireless device may establish communication with the second base station based on the signaling received from the first base station. At a first time, the wireless device may set the second base station in a deactivated state based on the signaling from the first base station configuring the second base station or establishing communication with the second base station. At a later time, the wireless device may set the second base station in an activated state and communicate with the first base station and the second base station.

Abstract: A device and method for a user equipment (UE) to implement power savings mechanisms when operating within a significant location. The UE identifies that the UE is at a significant location. The significant location is a location relative to a currently camped cell of a network. At a first time and at the significant location, the UE performs a type of operation related to the network connection. The UE stores information corresponding to the performance of the type of operation at the first time in a profile associated with the significant location. At a second time and at the significant location, the UE performs the type of operation related to the network connection. The performance of the type of operation at the second time is modified based on the information stored in the profile associated with the significant location.

Abstract: Apparatuses, systems, and methods for a wireless device to perform master cell group failure recovery in a dual connectivity cellular communication system. The wireless device may establish a first wireless link to a cellular network via a first cell group. The first cell group may be configured as a master cell group for the wireless device. The wireless device may establish a second wireless link to the cellular network via a second cell group. The second cell group may be configured as a secondary cell group for the wireless device. The wireless device may determine that link failure for the first wireless link has occurred. The wireless device may perform master cell group link failure recovery using the second wireless link based at least in part on the link failure for the first wireless link.

Abstract: Peer devices may wirelessly communicate with each other over a bidirectional sidelink logical channel (LCH) through an established bidirectional sidelink radio bearer. An initiating device of the peer devices may dynamically select a logical channel ID for establishing a fully bidirectional or semi-bidirectional SLRB. At least two alternative sidelink radio resource control (PC5-RRC) procedures may ensure the SLRB parameters are configured correctly in the established logical channel. The procedures also allow the network to configure a limited SLRB which is used to couple the SLRB configuration in the direction in which limited traffic (e.g. feedback information such as robust header compression feedback and/or status reports) is transmitted.

Abstract: This disclosure relates to techniques for supporting cell set based mobility. A network may provide configuration information to a wireless device, relating to a current cell and possibly to one or more other cells in one or more cell sets. The wireless device and network may take various measurements. In response to the measurements and the configuration information, the wireless device may perform a cell change to one of the other cells.

Abstract: Base stations, user equipment devices (UEs), and methods for a base station to supply service type-specific information to the UE. The base station may broadcast a first system information block (SIB) comprising scheduling information for a plurality of second SIBs, wherein each of the plurality of second SIBs corresponds to a respective service type of a plurality of service types, and wherein the second SIBs describe service type-specific capabilities of the base station. The plurality of service types may comprise two or more of enhanced mobile broadband, ultra-reliable low latency communications, and massive machine-type communications. The base station may broadcast the plurality of second SIBs according to the scheduling information of the first SIB, and may establish a connection and communicate with the UE using one or more service types and according to the service type-specific capabilities described by second SIBs corresponding to the one or more service types.
