Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) obtains, from a first cell, a first downlink reference timing and a first reference signal received power (RSRP) measurement, wherein the first RSRP measurement is a first reference RSRP, determines that the first downlink reference timing has changed based on a cell reselection from the first cell to the second cell performed while in a radio resource control (RRC) non-connected state, and obtains, from the second cell, while in the RRC non-connected state, based on the first downlink reference timing having changed more than a threshold, a second downlink timing and a second RSRP measurement, wherein the second RSRP measurement is a second reference RSRP.

Abstract: An apparatus may be configured to receive an instruction indicating one of a machine-learning (ML) channel state information (CSI) feedback scheme associated with a first spectral efficiency or a non-ML CSI feedback scheme associated with a second spectral efficiency; and report the CSI feedback to a network node using the indicated one of the ML CSI feedback scheme or the non-ML CSI feedback scheme. Another apparatus may be configured to select one an ML CSI feedback scheme associated with a first spectral efficiency or a non-ML CSI feedback scheme associated with a second spectral efficiency; transmit, to the UE, an instruction indicating the selected one of the ML CSI feedback scheme or the non-ML CSI feedback scheme; and receive, from the UE, the CSI feedback that is associated with the selected one of the ML CSI feedback scheme or the non-ML CSI feedback scheme.

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: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may determine a downlink (DL) positioning reference signal (PRS) measurement period for measuring and processing DL PRSs transmitted by a base station while the UE is in a radio resource control (RRC) INACTIVE state. While in the RRC INACTIVE state, the UE may measure and process DL PRSs during the DL PRS measurement period. In another aspect, a network entity may receive one or more parameters associated with a capability of a UE to measure and process DL PRSs while the UE is in a RRC INACTIVE state. Based on those parameters, the network entity may determine a DL PRS measurement period to be used by the UE while the UE is in the RRC INACTIVE state. The network entity may send, to the UE, information for determining the DL PRS measurement period.

Abstract: Apparatus, methods, and computer program products for wireless communication are provided. An example method may include receiving, from a network entity, a configuration indicative of a transmit power difference between a special cell in a first frequency band and a secondary cell without an SSB in a second frequency band. The example method may further include determining, based on a condition of an absence of a synchronization signal configuration for the secondary cell, a power of a signal associated with the secondary cell based on the transmit power difference and a measured power associated with the special cell. The example method may further include communicating, with the network entity, via the secondary cell and based on the power determined for the signal associated with the secondary cell.

Abstract: A positioning signal measurement method includes: transmitting, from a user equipment to a network entity, a positioning measurement gap indication corresponding to a positioning measurement gap supported by the user equipment for measurement of a positioning reference signal; receiving, at the user equipment from the network entity, an indication of a scheduled positioning measurement gap; receiving, at the user equipment, the positioning reference signal; and measuring, at the user equipment, the positioning reference signal.

Abstract: Methods, apparatuses, and computer-readable storage medium for wireless communication are provided. An example method may include transmitting, to a network entity, a capability for a transmission of one or more positioning SRS outside of an initial UL BWP during an idle state or an inactive state of the UE. The example method may further include receiving, from the network entity, a configuration for the transmission of the one or more positioning SRS outside of the initial UL BWP during the idle state or the inactive state. The example method may further include transmitting, to the network entity based on the configuration, the one or more positioning SRS outside of the initial UL BWP.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a reference signal received power (RSRP) associated with a reference signal (RS) broadcast by a network. The UE may further measure a received signal strength indicator (RSSI) using a plurality of resource elements (REs) that do not include the RS and excluding REs that do include the RS. Accordingly, the UE may determine a reference signal received quality (RSRQ) associated with the RS based at least in part on the RSRP and the RSSI. Numerous other aspects are described.

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.
