    Abstract: Apparatuses, systems, and methods for CCA power signaling during COT sharing. A UE may report a maximum EIRP for COT sharing as a UE capability, e.g., for a frequency range between 52.6 and 71 gigahertz. The UE may receive a Pout value for CCA based on the UE capability and may report an actual EIRP used for CCA to acquire the COT. For configured grant COT sharing, the UE may perform a directional LBT with a specific EIRP and beam detection for a transmission burst and report a Pout value for COT sharing based on the directional LBT, e.g., via a configured grant uplink control indication. For dynamic grant COT sharing, the UE may detect that an EIRP exceeds a threshold and report a Pout value for COT sharing via a medium access control (MAC) control element. The threshold may be based on a closed loop power control setting.

    Abstract: Apparatuses, systems, and methods for sounding reference signal (SRS) coverage enhancement. A user equipment device (UE) may receive a configuration for SRS time domain bundling from a base station and may transmit, to the base station, at least one SRS transmission in accordance with the configuration. The configuration may include an indication of (and/or indicate) one or more SRS transmission occasions. The configuration may be communicated via higher layer signaling or physical layer signaling. The RRC parameter may be an SRS-ResourceSet parameter or an SRS-Resource parameter and may include a nrofSlots parameter to indicate the number of slots, where a slot may correspond to an SRS transmission occasion. The MAC CE may include at least four bits indicating the number of slots. The DCI may include at least one field indicating the number of slots.

    Abstract: A user equipment (UE) associated with a wireless communication network is disclosed. The UE comprises one or more processors configured to form a sidelink group with one or more other UEs associated with the wireless communication network. In some aspects, the one or more processors are further configured to receive a sidelink (SL) groupcast message from a select UE of the one or more other UEs of the sidelink group, the SL groupcast message comprising a SL channel state information (CSI) request and a transmission of a SL channel state information reference signal (CSI-RS). In some aspects, the one or more processors are further configured to process the SL groupcast message; and selectively provide an SL CSI report derived based on a measured SL CSI, to the select UE, in response to processing the SL groupcast message.
