    Abstract: Mechanisms for directional channel occupancy monitoring for a frequency band among multiple networks are provided. In one aspect, a method of wireless communication includes monitoring, in a shared frequency band in a plurality of beam directions, for signals associated with one or more wireless networks different from the first wireless network. The monitoring includes: detecting, in the shared frequency band and in at least a first beam direction of the plurality of beam directions, a first signal associated with a second wireless network; and up-dating a channel occupancy list to indicate that at least a portion of the shared frequency band is occupied in at least the first beam direction. The method also includes transmitting, in the shared frequency band, a second signal in a second beam direction of the plurality of beam directions based on the channel occupancy list.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information, associated with a first sounding reference signal (SRS) resource set, indicating that a first one or more groups of SRS resource sets, from multiple groups of SRS resource sets, are associated with the first SRS resource set. The UE may receive an indication that a first group, from the multiple groups, is activated for SRS transmissions, the first group being included in the first one or more groups that are associated with the first SRS resource set. The UE may transmit an SRS using an SRS resource associated with the first SRS resource set based at least in part on the first group being activated and the first group being included in the first one or more groups. Numerous other aspects are provided.

    Abstract: A method of wireless communication performed by a first wireless communication device includes: receiving, in first sidelink (SL) resources of a shared frequency band comprising a first interlace of resource blocks (RBs) within one or more first RB-sets, a first SL communication in a first slot and a second SL communication in a second slot; and transmitting, in second SL resources of the shared frequency band comprising the one or more first RB-sets and a second interlace of RBs, a first SL feedback communication for the first SL communication and a second SL feedback communication for the second SL communication, wherein the transmitting the first SL feedback communication and the second SL feedback communication is based on a mapping of the first SL communication and the second SL communication to the second interlace of RBs in the one or more first RB-sets.

    Abstract: This disclosure provides systems, methods, and apparatuses for determining whether a channel state information reference signal (CSI-RS) is to be transmitted, and a configuration for transmission of the CSI-RS on a wideband based on an outcome of a listen-before-talk (LBT) operation in multiple sub-bands of the wideband. In one aspect, a base station may transmit sub-band usage information indicating sub-band availability before the CSI-RS, thereby allowing a user equipment (UE) to determine whether the CSI-RS will be transmitted and, if so, on which sub-bands the CSI-RS will be transmitted. Furthermore, rate matching configurations are provided based on whether sub-band usage has been received, based on which sub-bands are available. Still further, power configurations and resource element selection criteria are provided for wideband CSI-RS and CSI feedback.

    Abstract: Systems, methods, and mechanisms for modifying or cancelling uplink transmissions using dynamic slot format validation are provided. One aspect of the present disclosure includes a method of wireless communication performed by a user equipment (UE). The method of wireless communication includes determining that an uplink (UL) transmission is configured for a first time period; monitoring for a slot format indicator (SFI) validation associated with the first time period; and determining, based at least in part on the monitoring, whether to transmit the UL transmission during the first time period.

    Abstract: Disclosed are techniques for performing wireless communication. In some aspects, a first user equipment (UE) may determine that one or more physical sidelink feedback channel (PSFCH) instances are scheduled during a channel occupancy time (COT) corresponding to a sidelink transmission by the first UE to a second UE. In some examples, the first UE may transmit a COT maintenance signal during the one or more PSFCH instances, wherein at least one PSFCH symbol in the COT maintenance signal has a cyclic prefix extension.
