Abstract: Methods and apparatuses are provided for determining one or more parameters of an access point that can be set or adjusted to mitigate interference to other access points. A rise-over-thermal (RoT) threshold can be set at an access point based on one or more parameters, such as pathloss measurements, location of the access point, etc., such that interference from devices communicating with the access point can be mitigated. In addition, a noise floor, RoT threshold, etc., can be adjusted based on determining a transmit power difference, out-of-cell interference, and/or similar measurements.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for channel access for wireless communications. One aspect provides a method for wireless communications at a user equipment (UE). The method generally includes obtaining a channel occupancy time (COT) structure information (COT-SI) message and obtaining at least one downlink control information (DCI) indicating multiple beams and listen before talk (LBT) scheme indications associated with the multiple beams. The method generally includes determining an LBT scheme to be used for transmission via each of the multiple beams based on the LBT scheme indications and the COT-SI message, and outputting signaling for transmission on each of the multiple beams based on the LBT scheme.

Abstract: Wireless communications systems and methods related to narrow beam-based channel access for communications in a wireless communication network operating over an unlicensed spectrum are provided. A first wireless communication device receives, from a second wireless communication device, one or more signals associated with a beam parameter. The first wireless communication device determines, at each of a plurality of locations, a signal measurement for at least one received signal of the one or more received signals. The first wireless communication device determines, based at least in part on an p-th percentile signal measurement and a q-th percentile signal measurement of the signal measurements at the plurality of locations, whether the second wireless communication device satisfies an interference condition.

Abstract: Wireless communication methods and devices for selective receiver-assisted channel sensing are provided. In some aspects, one or more receivers (e.g., UEs) can be selectively configured to perform receiver-assisted channel sensing (e.g., class A channel sensing) using at least one of trigger signaling and channel sensing configuration by a BS, UE capabilities, or operational mode. For example, a method for wireless communication performed by a user equipment (UE) includes: sensing a channel based on at least one of a receiver-assisted channel sensing trigger, or a UE capability; and transmitting, to a base station (BS) based on the sensing, channel sensing information.

Abstract: Aspects relate to the amount of shared bandwidth to be used for channel occupancy time (COT) sharing. An initiator device may use a clear channel assessment procedure to gain access to wireless communication resources for a COT that will be shared between the initiator device and a responder device. In some examples, the responder device may determine the shared bandwidth based on information that is implicit in a transmission from the initiator device. For example, the responder device may determine the shared bandwidth based at least in part on a bandwidth of a transmission from the initiator device.

Abstract: A first apparatus may be implemented as a user equipment (UE) or a component thereof. The first apparatus may be configured to receive a pre-grant message from a base station on a wireless channel. The first apparatus may be further configured to determine an interference level associated with the wireless channel. The first apparatus may then indicate the interference level to the base station in response to the pre-grant message. A second apparatus may be implemented as a base station or a component thereof. The second apparatus may be configured to transmit a pre-grant message to a UE on a wireless channel. The second apparatus may be further configured to detect for an acknowledgement (ACK) message responsive to the pre-grant message from the UE. The second apparatus may then determine an interference level associated with the wireless channel proximate to the UE based on detecting for the ACK message.
