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: 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).
