    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.

    Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. The UE may receive a synchronization signal block or channel state information reference signal. The UE may transmit a channel state information report including a first indication of channel quality associated with the synchronization signal block or channel state information reference signal. The UE may receive a demodulation reference signal that is quasi co-located with the synchronization signal block or channel state information reference signal and associated with a physical downlink shared channel. The UE may transmit a hybrid automatic repeat request acknowledgment message or channel state information report including a second indication of channel quality associated with the demodulation reference signal of the physical downlink shared channel. The second indication of channel quality may include a differential measurement that is relative to the first indication of channel quality.

    Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for PUCCH/PUSCH DMRS bundling. A UE may transmit, to a network entity, a first indication of a maximum DMRS bundling duration for maintaining transmit phase coherence for transmitted DMRS. The UE may receive, from the network entity based on the first indication of the maximum DMRS bundling duration, a second indication of at least one of a DMRS bundling activation or a DMRS bundling duration. Based on the at least one of the DMRS bundling activation or the DMRS bundling duration, the UE may transmit at least one UL repetition including bundled DMRS.

    Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a user equipment (UE) may include receiving, from a base station (BS), a configuration for a channel state information (CSI) report setting, wherein a report quantity configured by the CSI report setting comprises at least measured channel characteristics of channel state information reference signal (CSI-RS) resources or synchronization signal block (SSB) resources for channel measurement associated with the CSI report setting and parameters of predicted channel characteristics associated with the CSI-RS resources or the SSB resources for channel measurement associated with the CSI report setting and transmitting, to the BS, a CSI report based on the CSI report setting.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a message 1 (msg1) report message, of a four-step random access channel (RACH) procedure, identifying information associated with a plurality of synchronization signal blocks (SSBs), wherein the information includes a plurality of SSB indices associated with the plurality of SSBs. The UE may receive, based at least in part on transmitting the msg1 report message, a message 2 (msg2) update message, of the four-step RACH procedure, with an indication of a downlink beam associated with an SSB index of the plurality of SSB indices. The UE may transmit a response message, based at least in part on receiving the msg2 update message, indicating a confirmation of the SSB index indicated in the msg2 update message or indicating a reversion to a different SSB index.

    Abstract: Methods, apparatuses, and computer-readable medium for reducing signaling overhead for a RedCap UE are provided. An example method may include receiving, from a base station, a grant associated with a set of random access channel (RACH) resources, a first part of the set of RACH resources for a reduced capability report including a set of overlapping resources that overlaps with a second part of the set of RACH resources for a physical uplink shared channel (PUSCH) repetition request. The example method may further include transmitting, in the set of overlapping resources to the base station, one or more repetition requests or one or more repetition number indications.
