The UE may transmit at least one instance of a RACH message in an uplink subband of an SBFD slot in accordance with the RACH configuration. The RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across an SBFD slot and an uplink slot.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently reporting channel state information (CSI) with limited overhead. In one aspect, if a user equipment (UE) is configured to transmit data and CSI to a base station periodically, the UE may transmit the CSI when the UE has data to transmit to the base station. In particular, the UE may transmit data and a CSI report during a transmission opportunity if the UE has data to transmit in the transmission opportunity. Otherwise, the UE may suppress transmission of the CSI report. In another aspect, a UE may be configured to transmit CSI to a base station when downlink channel conditions change. In particular, the UE may request to report CSI to the base station when channel conditions change, and the base station may trigger the UE to report the CSI after receiving the request.

For example, the adjustment to the transmission parameter may include adjusting a transmit power, adjusting a transmit frequency, adapting a transmission time, changing an antenna port, or a combination thereof. Additionally, or alternatively, the adjustment to the reception parameter may include refraining from joint channel estimation across a plurality of slots, adjusting a downscaling parameter or a frequency tuning associated with at least one reception antenna, refraining from blind decoding, or a combination thereof. Numerous other aspects are described.

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).

A user equipment (UE) may be configured to transmit, to a base station via a reconfigurable surface at a first transmission occasion, a first reference signal associated with a first reflection matrix configuration used by the reconfigurable surface to reflect signals, the first reflection matrix configuration included within a set of reflection matrix configurations. The UE may then transmit, to the base station via the reconfigurable surface at a second transmission occasion, a second reference signal associated with a second reflection matrix configuration used by the reconfigurable surface to reflect signals, the second reflection matrix configuration included within the set of reflection matrix configurations. The may then communicate with the base station via the reconfigurable surface based on transmitting the first reference signal, the second reference signal, or both.

Systems, methods, and devices for wireless communication that support mechanisms for uplink carrier selection for uplink random access channel (RACH) transmissions in a flexible cell configuration in a wireless communication system. A user equipment (UE) in a flexible cell selects at least one carrier for transmitting one or more uplink RACH transmissions to a base station. In aspects, the base station transmits an indication to the UE indicating which carrier the UE is to select for transmitting the one or more uplink RACH transmission. In aspects, the UE determines the carrier to transmit the one or more uplink RACH transmissions to the base station based on a comparison of reference signal measurements to predetermined thresholds. In these aspects, based on whether the measurements exceed the predetermined thresholds or not, the UE selects a carrier for transmitting the one or more uplink RACH transmission to the base station.

Uplink (UL) transmission in random access channel (RACH) on flexible cell

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for bandwidth part (BWP) dynamic adaptation in accordance with an energy level at a user equipment (UE). In some systems, the UE may implement techniques for power savings by operating according to a narrower BWP in accordance with an energy level at the UE. In some implementations, the UE may reduce the bandwidth size of the active BWP if the UE energy level satisfies a threshold. The UE may transmit signaling to the network indicating that the bandwidth size of the active BWP is reduced. Additionally, or alternatively, the UE may fall back to a default BWP if the UE energy level satisfies a threshold. For example, the UE may fall back to the default BWP prior to expiration of a timer configured to trigger the UE to fall back to the default BWP.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a base station, an indication of a set of resources for transmitting a set of phase-coherent sounding reference signals (SRSs).

In some examples, a base station may transmit different types of SSBs. For example, a base station may transmit a first type of SSB for UEs that do not support RISs and a second type of SSB for UEs that support RISs. A UE may search for and receive SSBs according to a capability of the UE.
