Abstract: Wireless communications systems and methods related to accessing a channel based on an interference condition in a wireless communication network are provided. 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: Methods, systems, and devices for wireless communications are described. A UE may cooperate with a group of one or more other UEs, where the UEs may each operate as a panel in a wireless communications system. To ensure updated information based on the cooperation status of the UE is provided to a network, the UE may receive one or more capability request messages from a base station. The UE may determine a group cooperation capability of the UE, based on a current group cooperation status of the UE. The group cooperation status may be based on the UE operating in cooperation with a group of UEs for communicating with the base station. The UE may then transmit, to the base station, one or more messages indicating the group cooperation capability of the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to switch from a first cell of a first distributed unit (DU) to a second cell of a second DU, wherein the first DU and the second DU are included in a set of DUs of a central unit (CU). The UE may communicate, using layer 1 (L1) or layer 2 (L2) signaling to change an activation status of at least one cell of the first DU or the second DU. The UE may switch from the first cell to the second cell in connection with the change to the activation status of the at least one cell of the first DU or the second DU. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to channel access in a shared radio frequency band in an unlicensed spectrum or a shared spectrum are provided. A wireless communication device determines a channel access procedure based on whether one or more channel access conditions are satisfied for accessing an unlicensed frequency band. The one or more channel access conditions are associated with at least one of sensing across multiple channel occupancy times (COTs), a transmission beam characteristic, a transmit power, a transmission duty cycle, or a beam dwell time. The wireless communication device transmits, based on the channel access procedure, a communication signal in the unlicensed frequency band.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a user equipment (UE) entering a dormant state with respect to a secondary cell group (SCG) of a node network (SN) having a primary serving cell (PSCell). In one aspect, the UE may maintain a parameter set for at least the PSCell while the UE is in the dormant state with respect to the SCG. For example, the UE may receive a parameter change message from either the SN or a master network (MN) and transmit a parameter change acknowledgment to either the SN or the MN. The parameter change message may be transmitted as one or both of a downlink control information (DCI) or media access control (MAC) control element (CE). The UE may transmit physical layer measurements to the SN based on the parameter set.

Abstract: Aspects presented herein may enable a remote UE to notify a base station about the availability of a relay UE that is not connected to the base station. In one aspect, a remote UE transmits, to a relay UE, a relay request via sidelink, the relay UE being in an RRC inactive mode. The remote UE receives, from the relay UE via the sidelink, an indication of relay availability in response to the relay request. The remote UE receives, from a base station, a configuration for relay of communication from the base station over the sidelink between the remote UE and the relay UE. The remote UE transmits or receives user data from the base station through the relay UE based on the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in communication with a base station may support updating a bandwidth part (BWP) width from a default configuration. The UE may identify a first BWP, where the first BWP is a default BWP for communication with the base station. The UE may receive an indication of a second BWP from the base station that is wider than the first BWP. The indication may, in some cases, be included in a remaining minimum system information (RMSI), a master information block (MIB), or the like. The UE may select, based on the received indication and an operating band of the base station, the second BWP for communications between the UE and the base station. The UE and the base station may communicate using the second BWP.

Abstract: A configuration utilising L1/L2 signaling to activate or deactivate a direct link in dual or multi-connectivity with relaying devices. The apparatus communicates with a base station using a direct link and using a relay link. The relay link comprises a side link between a first UE and a second UE and a second direct link between the second UE and the base station. The apparatus transmits or receives a request to deactivate the direct link based on a determination by at least one of the base station, the first UE, or the second UE that the direct link between the first UE and the base station is to be deactivated. The request to deactivate the direct link comprises L1 or L2 signaling. The apparatus receives a deactivation command to deactivate the direct link.

Abstract: Disclosed are systems and techniques for performing sidelink communications. For instance, a first client device can determine a first transmit power parameter for transmitting sidelink communications. The first transmit power parameter can either be received from a base station associated with the first client device or it can be a default parameter based on the first client device not being associated with a base station. The first client device can transmit, to a second client device, a first sidelink transmission having a first power level corresponding to the first transmit power parameter. The first client device can receive, from the second client device, a first sidelink reception having a second power level corresponding to a second transmit power parameter.
