Abstract: Certain aspects of the present disclosure provide techniques for an event-triggered partial update for a reference signal (RS) report by a user equipment (UE). An example method performed by a UE may include receiving, from a network entity, a configuration for reference signal (RS) measurement based reporting of a plurality of parameters, calculating the parameters, based on RS measurements, in accordance with the configuration, detecting an event, based on a change in value of at least one of the parameters relative to a previously reported value for that parameter, and transmitting an event-triggered report with a partial update of the parameters, based on the detection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a status of a repetition procedure associated with a radio resource control (RRC) connection request message of a four-step random access channel (RACH) procedure. The UE may invoke an activity state of an RRC connection setup message monitoring procedure based at least in part on the status of the repetition procedure. Numerous other aspects are described.

Abstract: The UE may perform a measurement of downlink reference signals from a serving cell and at least one neighbor cell and skip one or more RRM measurements based on a comparison of the measurement for at least one round of measurements and a threshold value. The measurement of the downlink reference signals may include a measurement of a Doppler shift, a measurement of a positioning reference signal, or a measurement of a reception timing drift based on the downlink reference signals.

Abstract: Certain aspects of the present disclosure provide techniques for communicating using power control parameters for multiple transmitter receiver point (mTRP) physical uplink shared channel (PUSCH) repetition. A method that may be performed by a user equipment (UE) includes receiving a sounding reference signal (SRS) configuration indicating at least a first SRS resource set and at least a second SRS resource set, receiving downlink control information (DCI) scheduling a first set of one or more PUSCH repetitions to a first TRP and a second set of one or more PUSCH repetitions to a second TRP, and transmitting the first and second sets of PUSCH repetitions using at least one of a first set of default power control parameters or a second set of default power control parameters.

Abstract: Aspects of the present disclosure provide techniques for inter-donor topology discovery in an Integrated Access and Backhaul (IAB) network during migration of an IAB-node. A method that may be performed by a first IAB-donor includes establishing a first signaling connection with an IAB-node, receiving an indication that the IAB-node has a second signaling connection with a second IAB-donor, and in response to receiving the indication: transferring, to the second IAB-donor, information related to the IAB-node, re-establishing traffic between the first IAB-donor and the IAB-node via a topology of the second IAB-donor, or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive channel state information (CSI) measurement resource (CMR) configurations for a first set of reference signals indicated to be associated with a first beam group and a second set of reference signals indicated to be associated with a second beam group. The UE may transmit a CSI report indicating a set of beams that includes a first beam associated with the first beam group and a second beam associated with the second beam group. Numerous other aspects are described.

Abstract: A base station may transmit, to a UE, at least one of the SS, the PBCH, the CORESET, or the SIB, via the plurality of resources based on the indication of the at least one initial access structure. In some aspects, the SS may be time-division multiplexed with the PBCH and may be frequency-division multiplexed with the CORESET and the SIB. In one aspect, the CORESET may be time-division multiplexed with the SIB. In another aspect, the CORESET may be frequency-division multiplexed with the SIB. In some aspects, at least one switching gap may be configured after the at least one initial access structure, the at least one switching gap being configured based on an SCS.

Abstract: A base station may determine one or more parameters of a PDSCH group including multiple PDSCHs for each beam in a plurality of beams, configure a plurality of resources for communication via the PDSCH group based on the determined one or more parameters of the PDSCH group, and transmit, to a UE, an indication of at least one parameter of the one or more parameters of the PDSCH group via the plurality of resources. The base station may also transmit, via the plurality of resources, one or more PDSCHs based on the at least one parameter of the one or more parameters of the PDSCH group. The UE may receive the indication of at least one parameter of the PDSCH group including multiple PDSCHs for each beam in a plurality of beams, and receive, from the base station, one or more PDSCHs based on the indication.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for requesting message repetition in random access procedures. In some aspects, a first random access message can be generated for a physical random access channel (PRACH) procedure. The first random access message can include a request for repetition of a third random access message. The request can be based on a criterion that is associated with at least one of a maximum allowed transmit power, or a PRACH transmit power. The first random access message can be output for transmission to a node to initiate a random access procedure with the node. In some aspects, one or more parameters related to a threshold for determining whether to include the request can be configured by the node.

Abstract: This disclosure provides systems, methods, and apparatuses for a wireless node to receive a phase tracking reference signal (PTRS) transmitted inside a downlink random access channel (RACH) message. The wireless node may receive a downlink RACH message that includes a PTRS based on an indication received in a downlink RACH message or a physical downlink control channel (PDCCH) associated with a downlink RACH message. In some aspects, the wireless node may utilize the PTRS for phase error correction or frequency error correction (such as frequency error caused by Doppler effects). This disclosure also provides systems, methods, and apparatuses for a component of a base station to provide an indication that a PTRS is included in a downlink RACH message. The indication may be provided in a downlink RACH message or a PDCCH associated with a downlink RACH message.
