    Abstract: Systems and methods for implementing uplink (UL) gaps to facilitate user equipment (UE) calibration are disclosed herein. A UE determines one or more slot patterns of a slot configuration that is repeated during time division duplex (TDD) communication with a base station. The UE determines a UL gap periodicity (defining periods covering an integer number of repetitions of the slot configuration). The UE then performs UE calibration during one or more semi-persistently configured UL slots of a period of the UL gap periodicity that correspond to UL indication(s) in one or more of a common configuration, a dedicated configuration, and/or a slot format indication (SFI) downlink control information (DCI) for the slot pattern(s) of the slot configuration. Methods of identifying particular semi-persistently configured UL slots of a period to use for the UL gap are also discussed. UL slot indications from dynamic DCI are not used for UL gap purposes.

    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: Techniques described herein include solutions for beam management in sidelink (SL) communications. In some aspects, user equipments (UEs) operating in SL are configured with a SL beam management resource pool by a base station. The SL beam management resource pool may be used to send a beam management message, such as a beam acquisition message, a beam failure recovery message, a beam maintenance message, etc. In some aspects, a resource in the SL beam management resource pool used to transmit the beam management message is selected based on an optimal beam determined by the UE. Resource pool configurations are provided for beamed transmission and beamed receiving, beamed transmission and quasi-omni receiving, and Rx beam training.

    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.
