Abstract: A neighbor cell list for a cell is maintained based on a received handover message that identifies at least one physical layer identifier. For example, the handover message may include measurement report messages (MRMs) generated by the access terminal being handed over. As another example, the handover message may include a neighbor cell list that is associated with the access terminal. The measurement report messages and the neighbor cell list associated with the access terminal will identify physical layer identifiers of cells in the vicinity of the source cell and, in some cases, in the vicinity of the access terminal being handed over. Upon receipt of the handover message, the neighbor cell list for the target cell is updated based on the physical layer identifiers identified by the handover message.

Abstract: Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon, which can be received and reported by a device to a source base station along with one or more parameters for disambiguating a target femto node. The source base station can communicate a handover message to the femto node or a related femto gateway along with the one or more parameters. The femto node or femto gateway can disambiguate the intended target femto node based in part on the one or more parameters, which can include applying one or more filters. Additionally, the femto node can broadcast multiple beacons to assist in disambiguation of the target femto node. Also, where complete disambiguation is not possible, the femto gateway can prepare multiple femto nodes for hand-in.

Abstract: Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon over an operating frequency of the macrocell base station, and the macrocell base station, and/or one or more network components, can identify the femto node based on one or more parameters reported by the device from receiving the beacon. The beacon can be transmitted at varying powers to ensure active hand-in triggering, mitigate interference and/or can be powered on and off for such purposes. In addition, a macrocell base station can regulate compressed mode periods during which a device can measure the femto node based on receiving information regarding device proximity to the femto node, or a device can generate proximity indication messages base on measuring the beacon signals, etc.

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.

For example, a method of wireless communication performed by a wireless communications device may include receiving, from a second wireless communication device, one or more signals associated with a beam parameter, determining, at each of a plurality of locations, a signal measurement for at least one received signal of the one or more received signals, and determining, based at least in part on a cumulative distribution of the signal measurements at the plurality of locations and a reference probability distribution, whether the second wireless communication device satisfies an interference condition. Other features are also claimed and described.

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.

Abstract: A method of wireless communication includes determining, by a communication device, a value of a counter associated with a listen-before-talk (LBT) operation. The method further includes, after determining the value of the counter and during a first portion of a deferral interval associated with the LBT operation, performing a first measurement of a particular duration to determine a first energy value. The method further includes, during a second portion of the deferral interval subsequent to the first portion, performing a second measurement of the particular duration to determine a second energy value. The method also includes determining whether to initiate a contention interval associated with the LBT operation based on the first energy value and further based on the second energy value.

In one aspect, the apparatus may determine an energy detection threshold of a reference bandwidth, the energy detection threshold being based on at least one of a transmit power or a power class. The apparatus may also measure an interference level of at least one signal. Additionally, the apparatus may adjust the energy detection threshold of the reference bandwidth based on a sensing bandwidth. The apparatus may also determine whether a transmission medium is available based on at least one of the adjusted energy detection threshold or the measured interference level of the at least one signal.

The methods, systems, and devices may enable a base station to transmit a measurement configuration for measuring interference (e.g., cross link interference (CLI)). The measurement configuration may include a measurement direction configuration for measuring the interference. Additionally or alternatively, the UE may select a measurement direction configuration for measuring interference based on the measurement configuration. The UE may measure interference based on the measurement configuration. The UE may transmit a measurement report to the base station. The measurement report may include an indication of the selected measurement direction configuration.
