Abstract: Various aspects of the present disclosure generally relate to wireless communication. 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: Certain aspects of the present disclosure provide techniques for inter-slot and intra-slot frequency hopping in full duplex. A method performed by a user equipment (UE) includes receiving scheduling information from a network entity, wherein the scheduling information schedules transmission of a plurality of uplink data channel repetitions in a plurality of slots according to a frequency hopping scheme that configures frequency hops between transmissions of repetitions of the plurality of uplink data channel repetitions. The method also includes taking one or more actions related to transmitting, according to the frequency hopping scheme, the plurality of uplink data channel repetitions in the plurality of slots based on the scheduling information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node and prior to transmission of a radio resource control (RRC) connection request message, a phase tracking reference signal (PTRS) indication that indicates a presence of a PTRS. The UE may transmit the RRC connection request message comprising the PTRS based at least in part on the PTRS indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for beam training a reconfigurable intelligent surface (RIS) for sidelink communications between UEs. A base station may transmit an indication of a resource pool to a receiving UE and a transmitting UE for beam training a RIS. The transmitting UE may identify a resource pattern for training the RIS using the indicated resource pool where the resource pattern is associated with a pattern of beams at the RIS. The transmitting UE may transmit a sidelink reference signal using the identified resource. The receiving UE may receive the reference signal via the RIS according the pattern of beams and transmit a beam report to the transmitting UE. Beam training may be based on a capability of the RIS to use either a different beamformer or a different RIS configuration on different subchannels of the same resource pool.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes a reconfigurable intelligent surface receiving, from a network entity, a synchronization signal block associated with a synchronization signal block index, reflecting the synchronization signal block as a set of multiple instances of the synchronization signal block via a corresponding set of multiple downlink transmit beams, receiving a random access message from a user equipment (UE) during a random access occasion that corresponds with the synchronization signal block index and on an uplink receive beam that corresponds with one of the set of multiple downlink transmit beams, identifying the phase-change pattern of multiple phase-change patterns that corresponds to the uplink receive beam, and reflecting the random access message to the network entity by applying the phase-change pattern to antenna elements of the reconfigurable intelligent surface that reflect the random access message to the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit one or more messages indicating a first time period having a duration prior to expected traffic being available for transmission at the UE, and indicating a size associated with the expected traffic (e.g., a quantity of bits). In some examples, the one or more messages may include a UE assistance information (UAI) message or a buffer status report (BSR) message. The UE may receive a response message based on the one or more messages indicating that a network entity is to enter a sleep mode during a second time period based on the first time period and the size associated with the expected traffic. In some examples, the network entity may enter the sleep mode based on the first time period and the size associated with the expected traffic.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a base station may participate in a one-shot initial access procedure involving a reconfigurable intelligent surface (RIS) divided into a number of sub-RISs, each sub-RIS associated with a different configuration for reflecting signaling from the base station. In some aspects, the base station may configure each sub-RIS to have a different frequency shift and transmit, to the UE, a parameter indicating a quantity of synchronization rasters associated with each of a set of beams that the base station may use as part of the one-shot initial access procedure. The UE may, for each beam, monitor a quantity of monitoring occasions corresponding to the quantity of synchronization rasters and transmit random access signaling to the base station based on which synchronization raster of which beam provides a greatest signal strength at the UE.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may communicate with a user equipment (UE) via a reconfigurable intelligent surface (RIS) which is capable of adjusting a reflection characteristic to reflect incident signaling in different directions. The base station and the RIS may establish a beamformed connection and, in some scenarios, the base station and the RIS may experience a beam failure. In such scenarios, the base station, the UE, and the RIS may participate in a two-step beam training procedure to reduce an amount of possible beam pair hypotheses that the communicating devices test in order to re-establish communication between the base station and the UE via the RIS. The two-step beam training procedure may include a first procedure in which the RIS selects a suitable beam toward the base station and a second procedure that leverages the selected beam.
