Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for determining whether to drop an additional signal at an edge interlaced resource block (IRB) of a common interlace. A user equipment (UE) may transmit additional signals via IRBs of the common interlace to improve an occupied channel bandwidth (OCB) of a feedback transmission and may drop one or more additional signals that are proximate (e.g., in frequency) to feedback indications of a configured interlace. To ensure the OCB of the transmission satisfies an OCB threshold, the UE may determine whether to drop an additional signal at an edge IRB, despite the edge IRB being proximate to a feedback indication, according to one or more rules that may be specific to edge IRBs.

Abstract: Methods, systems, and devices for wireless communication are described to support accounting for contention-exempt synchronization signal blocks (SSBs) when validating one or more channel state information reference signals (CSI-RS). A base station may transmit, to a user equipment (UE), an indication of the one or more contention-exempt SSBs, and the UE may determine to monitor for a configured CSI-RS if resources assigned to the CSI-RS fall within a time frame associated with the one or more contention-exempt SSBs. Similarly, the base station may transmit configured CSI-RS if resources assigned to the CSI-RS fall within a time frame associated with the one or more contention-exempt SSBs. The time frame associated with the one or more contention-exempt SSBs may include a slot that includes the SSB(s), a symbol that includes the SSB(s), symbols between the SSB(s), slots between the SSB(s), or any combination thereof.

Abstract: Example aspects include a method, apparatus, and computer-readable medium for wireless communication at user equipment of a mobile network, comprising receiving, from a base station via a first beam, a pre-grant message requesting the UE to perform a listen-before-talk (LBT) procedure on a second beam. The aspects further include performing, according to the pre-grant message, the LBT procedure on the second beam. Additionally, the aspects include indicating, to the base station, whether the LBT procedure was successful.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter node may determine a set of desired transmit beams to use for transmissions during a channel occupancy time (COT), wherein each transmit beam in the set of desired transmit beams is associated with an energy detection threshold (EDT). The transmitter node may configure a sensing beam associated with a directional listen-before-talk (LBT) procedure, wherein the sensing beam is associated with an EDT that is at least as strict as a strictest EDT associated with the set of desired transmit beams. The transmitter node may transmit using the set of desired transmit beams during the COT, wherein the COT is initiated based at least in part on an indication that the directional LBT procedure succeeded using the sensing beam. Numerous other aspects are described.
