Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration that indicates one or more measurement objects, wherein a measurement object of the one or more measurement objects indicates a synchronization signal block (SSB) frequency of a configured bandwidth part (BWP). The UE may determine, from the one or more measurement objects, a serving cell measurement object based at least in part on an active BWP of the UE, wherein the serving cell measurement object is associated with an SSB frequency in the active BWP. Numerous other aspects are described.

Abstract: This disclosure provides systems, apparatus, methods, and computer-readable media for beam switching by a repeater node that forwards communications from one of a first node or a second node to the other of the first node or the second node. For example, after a change of position by the second node, the first node may provide the repeater node an instruction to perform a beam change operation to communicate with the second node. In some aspects, performing the beam change operation by the repeater node may improve reliability of wireless communications, such as by focusing signal energy in a particular direction. Further, a beam change delay time interval or a scheduling of the beam change delay time interval may be selected based on scheduling associated with other nodes, which may reduce a number of messages sent to the repeater node (such as by reducing instructions to change beam directions).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a paging early indication (PEI) physical downlink control channel communication with tracking reference signal (TRS) availability information at a location that is based at least in part on a length of a bitmap to be used for indicating a PEI. The UE may receive a TRS if the TRS availability information indicates that the TRS is to be transmitted. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for a physical downlink control channel (PDCCH) ordered random access channel (RACH) procedure. The RACH procedure may be associated with a cell-defining synchronization signal block (SSB) or non-cell-defining SSB. A method for wireless communications by a user equipment (UE) includes transmitting an indication of one or more capabilities of the UE, receiving a PDCCH that orders the UE to perform a RACH procedure on an uplink carrier based on the one or more capabilities of the UE, determining a minimum gap between a last symbol of the PDCCH and a first symbol of a RACH message, wherein the minimum gap includes a half-duplex (HD) switching delay, and performing the RACH procedure on the uplink carrier when a gap between the last symbol of the PDCCH and the first symbol of the RACH message is equal to or larger than the minimum gap.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving a PDCCH order for a MSG 1 transmission having a first DMRS that is quasi co-located with a first reference signal, and receiving a corresponding RACH message having a second DMRS that is quasi co-located with a second reference signal, wherein the first reference signal and second reference signal are different.

Abstract: This disclosure provides systems, methods and apparatuses for efficient signaling of feedback regarding communications of a relaying operation. In some aspects, a relay node may defer feedback regarding reception of a first communication until relaying feedback regarding the payload of the first communication, thereby reducing overhead and signaling burden. In some aspects, a relay node may skip the transmission of feedback regarding the first communication altogether, either on the assumption that the link between the relay node and the first wireless node is reliable, or on the basis of the first wireless node being able to infer the reception of the first communication based on subsequent communications. In some aspects, a relay node may be enabled to skip forwarding of feedback from a second wireless node, such that the first wireless node can infer that the payload was received if no negative feedback associated with the payload is received.

Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) establishing and utilizing a reference timing for a carrier or cell with multiple transmission and reception points (TRPs). A UE may receive a downlink signal on each of a plurality of component carriers (CCs), and determine respective timing events (e.g., slot boundaries, subframe boundaries, etc.) corresponding to each of the plurality of CCs. The UE may then determine a reference time for a first CC of the plurality of CCs. This reference time corresponds to a function of two or more timing events corresponding to different TRPs utilizing the first CC. The UE then determines a relative timing difference between the plurality of CCs based on this determined reference time. Other aspects, embodiments, and features are also claimed and described, including determining and utilizing a reference time on an uplink CC.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In some aspects, a base station may send a beam modification command that indicates a set of transmit beam indexes corresponding to a set of transmit beams of a base station, and each transmit beam index of the set of transmit beam indexes may indicate at least a transmit direction for transmitting a transmit beam by the base station. The base station may send, in association with the beam modification command, a reference signal using at least one transmit beam of the set of transmit beams, where a first portion of the reference signal is sent in a first set of symbols and a second portion of the reference signal is received in a second set of symbols.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify a scaling factor associated with determining a periodicity of backhaul physical random access channel (PRACH) resources. The wireless communication device may determine, based at least in part on the scaling factor, the periodicity of the backhaul PRACH resources. The periodicity of the backhaul PRACH resources may be extended as compared to a periodicity of access PRACH resources. Numerous other aspects are provided.

Abstract: Disclosed are techniques for transmitting reference signals (RS) for positioning. A method comprises transmitting or providing an instruction to transmit a first set of RS to a user equipment (UE) in accordance with a first set of RS transmission parameters, receiving a report containing information indicating whether a measurement performed by the UE is limited by a signal-to-noise ratio (SNR) of the first set of RS or a bandwidth of the first set of RS, determining a second set of RS transmission parameters using the received report, wherein the second set of RS transmission parameters is different from the first set of RS transmission parameters, and transmitting a second set of RS to the UE in accordance with the second set of RS transmission parameters, or providing the second set of RS transmission parameters to a base station.
