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: Apparatuses, systems, and methods for selecting channel access mechanisms in wireless communications, and particularly in 3GPP NR-U. For example, an appropriate listen-before talk (LBT) channel access category (Cat) may be defined for certain messages, such as certain DL and/or UL control messages and certain RACH messages. For other messages, an appropriate Cat may be signaled by the base station, e.g., in a DCI message or SIB. Mechanisms are provided for the base station to signal to the UE certain channel access profile parameters, such as an appropriate LBT Cat, CAPC, and/or CP extension. Mechanisms are also provided for adjustment of contention window duration.

Abstract: A base station and wireless communication (UE) may perform type II CSI-RS port selection based at least on partial reciprocity between an uplink path and a downlink path between the base station and the UE. The base station may identify dominant signal paths between the base station and the UE, based on measurements performed during uplink transmissions, and may transmit, to the UE, corresponding information indicative of CSI measurement and reporting configuration that may include a single measurement resource or multiple measurement resources. Each measurement resource may include multiple-port CSI-RS ports. The UE may indicate, to the base station, selection of a measurement resource when multiple measurement resources are configured, and may also report layer independent or layer common selection of a subset of CSI-RS ports included in the indicated single measurement resource or multiple measurement resources. Further enhancements include frequency domain compression enhancement and dynamic codebook parameter reconfiguration.

Abstract: Systems, devices, and techniques for wireless communications based on one or more transmission configuration indicator (TCI) states are described. A described technique performed by a user equipment (UE) includes receiving a first downlink channel based on a current TCI state; receiving a physical downlink shared channel (PDSCH) in a first slot, the PDSCH carrying a radio resource control (RRC) activation command in the first slot, the RRC activation command indicating a switch to a target TCI state; waiting until an end of a switching period triggered by the RRC activation command to use the target TCI state, the switching period being based on a RRC processing delay; and receiving, based on the end of the switching period, a second downlink channel based on the target TCI state in a second slot.

Abstract: Systems, devices, and techniques for measuring and reporting cross-link interference (CLI) are described. A described technique includes determining, by a first wireless device, whether to perform a CLI measurement; determining a quantity of activated transmission configuration indicator (TCI) states associated with a second wireless device; performing the CLI measurement based on the quantity of activated TCI states; and transmitting a CLI report in response to the CLI measurement.
