Abstract: Methods and apparatuses are provided for determining a transmission power cap for one or more devices based at least in part on pathloss measurements to one or more access points received from the one or more devices. A common transmission power cap can also be computed for assigning to devices communicating with an access point, and the transmission power cap for a given device can be adjusted when the transmission power is at or a threshold level from the common power cap to conserve signaling in the wireless network. Adjustment of the transmission power cap can additionally or alternatively be based on a received power at an access point related to signals from the device, an interference report from one or more access points, and/or the like.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication associated with performing listen-before-talk relative to a channel occupancy time (COT). Accordingly, the UE may transmit, to the base station, an uplink communication, where the uplink communication is transmitted using a listen-before-talk (LBT) procedure based at least in part on the indication. For example, the LBT procedure may be selected from a category 1 (Cat1) LBT procedure, a category 2 (Cat2) LBT procedure, or a category 3 (Cat3) LBT procedure based at least in part on the indication (e.g., included in a radio resource control message). The LBT procedure may be further based at least in part on downlink control information from the base station. Numerous other aspects are described.

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: Aspects of the present disclosure include methods, apparatuses, and computer-readable medium for transmitting a capability signal to a network entity, wherein the capability signal indicates whether the UE is capable of supporting an uplink (UL) bandwidth that is equal to or less than a downlink (DL) bandwidth for communication over an unlicensed band; and exchanging a signal between the UE and the network entity over the unlicensed band according to the capability signal. Some alternative or additional aspects include methods, apparatuses, and computer-readable medium for receiving a signal from a network entity, wherein the signal indicates that short control signal exemption (SCSt) is applied to a synchronization signal block (SSB) transmission of one or more network entities over an unlicensed band; and skipping SSB presence detection of the one or more network entities in response to the signal.

Abstract: A node configured for communication in a wireless communication network transmits, following a listen before talk process, at least one transmission within an operating channel bandwidth in response to a sensed energy in the operating channel being less than both a first energy detection threshold (EDT) value determined as a function of the channel bandwidth, and a second predetermined EDT value obtained from the node. The first EDT value is determined as the function of the channel bandwidth and further as a function of a ratio of a maximum transmitter power to an intended transmitter power, the intended power transmitter power being less than or equal to the maximum power. When the intended and maximum powers are equal, the first EDT value is determined only as the function of the channel bandwidth. The second energy detection threshold value may be determined as a function of a reference channel bandwidth.
