Abstract: Certain aspects of the present disclosure provide techniques for signaling and scheduling to enable network configured small gaps in intra-band inter-frequency measurement. A method that may be performed by a user equipment (UE) includes receiving, from a serving cell operating on a first frequency, an indication that synchronization signal block (SSB) indexes of a target cell operating on a second frequency can be derived from timing of the serving cell; and deriving an SSB index of the target cell, based on the timing of the serving cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling including an indication of a first measurement gap configuration associated with a first bandwidth part (BWP) and associated with measurements for communications at the UE over a frequency outside of the first BWP in a frequency domain. The UE may receive, from the base station, a downlink message including an indication of the first BWP. The UE may then communicate with the base station during a first time interval based on the indication of the first measurement gap configuration and the indication of the first BWP.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support processing high bandwidth position references signals (PRSs) at a reduced capability (RedCap) User equipment (UE). The UE reports a frequency hopping capability and a measurement gap. In a first aspect, a method of wireless communication includes a method of wireless communication performed at a User Equipment. The UE transmits an indication of a capability of the UE to perform receive frequency hopping to measure a downlink positioning reference signal (DL-PRS), where the indication of the capability includes at least one of a maximum supported PRS bandwidth (BW) with frequency hopping, a possible number of frequency hops, maximum BW per hop, and minimum hop overlap. Optionally, the UE also transmits a report of a total PRS BW measured by the UE and/or an indication that a measurement with frequency hopping was performed. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a combination of a first band and a second band, whether a measurement offset is to be applied for a neighbor measurement on the second band based at least in part on an estimated impact of interference from the first band on the second band; and selectively apply the measurement offset for the neighbor measurement based at least in part on whether the measurement offset is to be applied; or selectively report the measurement offset to a base station associated with the neighbor measurement based at least in part on whether the measurement offset is to be applied. Numerous other aspects are provided.

Abstract: Techniques and apparatus for intra-frequency measurement of Layer 3 (L3)-based channel state information reference signals (CSI-RSs) are described. An example method that may be performed by a user equipment (UE) includes transmitting an indication based on a UE capability to simultaneously receive downlink data from a serving cell on one or more first resources and measure one or more CSI-RSs from a target cell on one or more second resources. The one or more first resources at least partially overlap the one or more second resources in a time domain and a frequency domain. The method also includes performing a CSI-RS measurement procedure, based on the UE capability.

Abstract: This disclosure provides systems, methods and apparatuses for user equipment (UE)-side and network-side mitigation of intermodulation (IM) interference, such as IM interference associated with multi-radio access technology communications. For example, the UE or a base station may detect an IM interference condition, and may perform an IM mitigation action based on detecting the IM interference condition. The UE may reduce an uplink transmit power so that IM interference on the downlink is reduced. Various base station IM mitigation actions are provided, such as suspending scheduling on a bearer, using a scheduling pattern that avoids concurrent transmission, reducing a maximum transmit power of an uplink grant of the UE, allocating resource blocks or bandwidth parts that do not overlap with an IM interference resource, changing a secondary cell group channel to a non-interfering channel, releasing a secondary cell group channel, deactivating a carrier, or changing a channel of the UE.
