Abstract: Techniques described herein includes solutions for mitigating interference related to antenna switching. A user equipment (UE) may determine a potential for interference to data reception on a second frequency band due to antenna switching associated with transmission of reference signals on a first frequency band. In response to the determination, the UE may select one or more interference mitigation measures based on an operating mode of the UE and one or more UE parameters. An interference mitigation measure may include backing off on a reported value, such as a channel quality indicator (CQI), rank indicator (RI), or reference signal received power (RSRP). The interference mitigation measure may further include skipping reference signal transmission on the first frequency band and the antenna switching associated therewith.

Abstract: Disclosed are methods, systems, and computer-readable media to perform operations including: receiving an uplink grant associated with pre-scheduling from a base station; in response to the uplink grant, transmitting first data having a first priority to the base station; determining whether there is a remaining uplink resource associated with the uplink grant; and in response to determining that there is the remaining uplink resource, transmitting second data having a second priority to the base station using the remaining uplink resource, wherein the second priority is lower than the first priority.

Abstract: User equipment may include a transmitter and a receiver coupled to an antenna to enable the user equipment to transmit and receive user data with a base station of the wireless network. However, the user equipment may perform power-consuming searches to determine a base station for connection. Furthermore, the connection may be affected by blockages and transitions during mobility scenarios. As such, it may be beneficial for the user equipment to implement mobility procedures. For example, the user equipment may form links with multiple base stations of a cell cluster for transitioning. In another example, the wireless network may generate a map with locations of base stations and beam characteristics for the user equipment to determine coverage areas and decrease a number of transitions. Still in another example, the user equipment may receive blockage information to predict a blockage and implement mobility procedures to maintain wireless service during a blockage.

Abstract: User equipment in close proximity may transfer data and control information. For example, the user equipment may exchange data or data sets between each other. Each user equipment can receive and transmit data using radio access technologies. A group of user equipments may include active user equipment and passive user equipment. Active user equipment connects with one or more base stations and transfers data on a wireless communication network via the base station. The active user equipment may communicate with other active user equipment and passive user equipment. Passive user equipment may not connect to any base station and/or the wireless communication network and may communicate with other passive user equipment and active user equipment (e.g., via a sidelink, peer-to-peer, or device-to-device channel).

Abstract: Apparatuses, systems, and methods for QoS impact mitigation during unavailability of RAN support of network slicing, e.g., in 5G NR systems and beyond. A UE may determine, while connected to a first cell of a network, whether handover instructions include DRB setup instructions on a second cell of the network for a PDU session established towards a first network slice on the first cell. The UE may, upon expiration of a timer initiated in response to the determination and/or confirmation that the second cell does not support network slicing, route, upon determining that there is not a neighboring cell that supports the first network slice and/or that there is not a routing rule for the first network slice that allows routing of traffic to another established DRB, user plane traffic to an eMBB DRB.
