Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a physical random access channel (PRACH) message corresponding to a PRACH occasion, wherein the PRACH occasion comprises a dedicated PRACH occasion or one of a plurality of PRACH occasions comprising at least one shared PRACH occasion associated with a two-step random access channel (RACH) procedure and a four-step RACH procedure, wherein the PRACH message includes a request for physical uplink shared channel (PUSCH) repetition corresponding to a radio resource control (RRC) connection request message of the four-step RACH procedure. The UE may transmit at least one PUSCH repetition associated with the RRC connection request message based at least in part on the request. Numerous other aspects are described.

Abstract: Aspects of the present disclosure allow a UE to request, in an anchor carrier on one frequency band, a base station to configure and transmit A-TRS in an SSB-less secondary carrier on a different frequency band. The UE transmits, in a first cell served by the anchor carrier, a request for A-TRS. Based on the request, the UE receives, in a second cell lacking SSB transmissions served by the secondary carrier, the A-TRS based on the request. The base station may also control transmission of the A-TRS in the SSB-less secondary cell based on a timer derived from the request. Using the A-TRS, the UE may apply AGC and time/frequency tracking loop operations prior to receiving a PDSCH in the SSB-less secondary cell, thereby improving reception performance of downlink data transmissions in the secondary carrier. Thus, network energy savings provided by SSB-less secondary carriers may be obtained in inter-band CA.

Abstract: Certain aspects of the present disclosure provide techniques for configuring a reconfigurable intelligent surface (RIS) for wireless communication. A method that may be performed by a base station (BS) includes transmitting one or more parameters corresponding to a time period for the RIS to adapt to user equipment (UE) configuration information, the UE configuration information for configuring the RIS for RIS-assisted communication between the BS and a UE, the one or more parameters comprising a number of symbols indicative of a duration of time. The method also includes transmitting, via the RIS and separately from transmitting the one or more parameters, a control channel to the UE scheduling communication of a data channel with the UE via the RIS. The method also includes communicating, via the RIS, the data channel with the UE the duration of time after transmitting the control channel to the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, information that configures a periodic bandwidth part (BWP) switching pattern that indicates a sequence of BWPs, wherein each BWP in the sequence of BWPs is associated with a respective network state. The UE and the network node may communicate according to the periodic BWP switching pattern, wherein the UE and the network node may communicate by sequentially switching among the BWPs in the sequence of BWPs indicated in the periodic BWP switching pattern, wherein each BWP in the sequence of BWPs is associated with a configuration corresponding to the respective network state associated with the BWP. Numerous other aspects are provided.

Abstract: In some implementations, a base station may send, to a user equipment (UE), a message indicating that an RF sensing signal is to be used for the RF sensing, wherein the message indicates: the RF sensing signal comprises a modified synchronization signal block (SSB) for supporting both sensing and initial access/mobility, or the RF sensing signal comprises a non-SSB sensing reference signal (S-RS) of a secondary cell (Scell) and has a quasi co-location (QCL) relationship with a root SSB of a primary cell (Pcell). The base station also may transmit the RF sensing signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first configuration of a first bandwidth part (BWP) associated with a primary cell of a communication link. The UE may receive an indication of a second configuration of a second BWP associated with a secondary cell, the second configuration of the second BWP being associated with refraining from measuring of channel state information reference signals (CSI-RSs). Numerous other aspects are described.

In some aspects, a user equipment (UE) may detect, using a low-power receiver of the UE, a low-power synchronization signal (LP-SS) that is associated with a first coverage area that is larger than a second coverage area associated with a legacy synchronization signal block. The UE may monitor, using the low-power receiver, for a low-power wake up signal, based at least in part on the LP-SS, that is associated with a third coverage area that is larger than a fourth coverage area associated with a legacy wake up signal. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station via a reconfigurable surface, a set of reference signals reflected by the reconfigurable surface using a set of precoder configurations. In some aspects, the set of reference signals are transmitted within a set of reference signal occasions of a sweep procedure associated with configuring the reconfigurable surface with different precoder configurations of the set of precoder configurations for reflecting signals. The UE may additionally transmit, to the base station via the reconfigurable surface, a feedback message including an indication of at least one precoder configuration of the set of precoder configurations based on receiving the set of reference signals. The UE may then receive, from the base station via the reconfigurable surface, a downlink transmission based on transmitting the feedback message.
