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.

Channel state information triggering for uplink dominant traffic

Methods, systems, and devices for wireless communications are described. 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.

Techniques for successive tuning using a reconfigurable surface

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

Various aspects of the present disclosure generally relate to configurations for new radio (NR) devices with reduced capabilities. In some aspects, a user equipment (UE) may determine a configuration from stored configuration information, where the configuration specifies a subset of features that NR UE with reduced capabilities is to support. The UE may communicate according to the configuration of reduced capabilities, or fall back to a set of further reduced UE capabilities. Numerous other aspects are provided.

Capability configurations for new radio redcap devices

Methods, systems, and devices for wireless communications are described. A base station that may include at least two transmission reception points (TRPs) next to a high speed train (HST) may transmit, to a user equipment (UE) on the HST, an indication of a quasi co-location (QCL) relationship indicating a relationship between a plurality of tracking reference signals (TRSs) and a demodulation reference signal (DMRS) of a data channel. The plurality of TRSs may include a first TRS and a second TRS. The UE may receive, from a first TRP, the first TRS associated with an occasion of the data channel, and receive, from a second TRP, the second TRS associated with the occasion of the data channel. The UE may perform, based on the indication of the QCL relationship, a channel estimation procedure for the data channel based on the DMRS, the received first TRS, and the received second TRS.

Quasi co-location type for doppler pre-compensated reference signal

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for performing initial access procedures including transmitting or receiving synchronization signal blocks (SSBs) based on a capability of a user equipment (UE) to use reconfigurable intelligent surfaces (RISs). In some examples, a base station may transmit SSBs using two synchronization raster grids. For example, the base station may transmit SSBs on a first synchronization raster grid for UEs that do not support RISs and on a second synchronization raster grid for UEs that support RISs. 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.

Transmitting synchronization signal block via reconfigurable intelligent surfaces

Methods, systems, and devices for wireless communications are described. A method for wireless communication may include receiving a single frequency networked composite reference signal (SFNed RS) at a first port of a user equipment (UE) and receiving a reference signal (RS) at a second port of the UE that is different than the first port of the UE. The method may also include performing channel estimation for at least one of the first port or the second port based at least in part on receiving the SFNed RS and the RS. A method for wireless communication may include transmitting a first portion of an SFNed RS from a first port of a first transmit/reception point to a UE and transmitting a downlink control information message to the UE that indicates at least one transmission configuration indicator state identifier that identifies the SFNed RS.

Numerous other aspects are provided.

A size of the second stage may be restricted by an upper limit associated with an available set of uplink resources for transmitting the feedback information. Limiting the size of the second stage may include reducing a size of second information generated for the second stage, yielding third information for the second stage. The third information may be transmitted with first information generated for the first stage. Limiting the size of the second stage may also include generating second information having a reduced size based on determining that the upper limit may be exceeded. The reduced-size second information may be transmitted with the first information.
