Abstract: Techniques and apparatus for adapting bandwidth operation for full duplex user equipments (UEs) are described. One technique involves a base station (BS) determining a plurality of resource bandwidths (BWs) within an active BWP that are available to be used for communications by one or more UEs. An indication of at least one resource BW of the plurality of resource BWs is signaled to a UE. Communications between the BS and the UE are performed on the at least one resource BW.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration message that indicates a radio resource allocation and a transmission scheme for one or more first configured grant-small data transfer (CG-SDT) occasions and one or more second CG-SDT occasions. The one or more second CG-SDT occasions are at least partially nested, in time, frequency, or a combination thereof, within the one or more first CG-SDT occasions. The UE may therefore transmit, to the base station, an uplink communication within the one or more first CG-SDT occasions or the one or more second CG-SDT occasions, using the radio resource allocation and the transmission scheme. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that schedules an uplink communication in an uplink frequency band. The UE may transmit, at an uplink frequency within the uplink frequency band, the uplink communication with a power that varies over the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be receive a grant configuration including multiple set of parameters, and the UE may select a set of parameters from the configured grant based on a channel condition. In some examples, the UE may be configured to signal to a network (e.g., a base station) the selected set of parameters and their corresponding parameter values. For example, the UE may be configured to signal the selected set of parameters over semi-static signaling (e.g., radio resource control (RRC) messaging) or dynamic signaling (e.g., medium access control-control element (MAC-CE) messaging, uplink control information (UCI) messaging, or the like). By configuring the UE with multiple set of parameters, the UE may adapt to changing channel conditions, which may provide higher reliability and lower latency for wireless communications, as well as reduce power consumption for the UE.

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.
