摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, to an open radio access network distributed unit (O-DU) associated with the network node, a grant that permits use of a shared spectrum resource, the grant indicating a first cryptographic checksum for a given timeslot in which the shared spectrum resource is granted. The network node may receive, from the O-DU, a transmission that includes a second cryptographic checksum. The network node may transmit the transmission via the shared spectrum resource based at least in part on an authentication of the transmission, the authentication involving the grant being accepted by the open radio access network radio unit (O-RU) based at least in part on a verification that the second cryptographic checksum corresponds to the first cryptographic checksum. Numerous other aspects are described.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station using UE cooperation. For example, a first UE may transmit an uplink signal indicating a request for the base station to transmit a UE discovery request signal to a second UE. In response to transmitting the uplink signal, the first UE may receive a sidelink signal from the second UE. The sidelink signal may indicate that the second UE may be available for a cooperative link with the first UE. In some cases, based on the sidelink signal, the first UE may establish the cooperative link with the second UE. In some examples, based on establishing the cooperative link, the first UE may receive downlink communications from the base station via at least sidelink communications from the second UE over the cooperative link.

摘要： 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.

摘要： Methods, systems, and devices for wireless communications are described. In some examples, a wireless communications system may support user equipment (UE) cooperation. When a first UE and second UE are in a cooperative configuration, a base station may use the first UE to request and obtain channel information for the second UE. For example, the base station may transmit a request for channel information to the first UE and the first UE may relay the request to the second UE. The second UE may determine the channel information and transmit a report including the channel information to the first UE, where the first UE may relay the report to the base station. In some examples, the report, the request, or both may be exchanged between devices using medium access control control element (MAC-CE)-based methods or using downlink control information (DCI)-based methods. The DCI-based methods may involve relaxed timings.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration indicating one or more cells configured for layer 1/layer 2 (L1/L2) mobility. The UE may receive a message indicating at least one cell of the one or more cells. Accordingly, the UE may release the at least one cell in response to the message. Numerous other aspects are described.

摘要： Methods, systems, and devices for wireless communications are described. In some examples, a first user equipment (UE) may receive an active communication configuration between the first UE and a base station. The first UE may receive a UE cooperation configuration between at least the first UE and a second UE. The UE cooperation configuration may include a configuration for communicating messages between the base station and a set of antenna panels corresponding to at least the first UE and the second UE as a single entity. The UE cooperation configuration may include parameters associated with the second UE. The first UE may identify, from the set of antenna panels, an antenna panel for reception of a downlink message based on the UE cooperation configuration. The first UE may transmit a message to the base station, the second UE, or both in response to the downlink message.

摘要： Wireless communications systems and methods related to channel occupancy time (COT) sharing for sidelink communications are provided. A first user equipment (UE) receives, from a second UE, a first sidelink transmission during a first channel occupancy time (COT), where the first COT is associated with the second UE. The first UE determines whether the second UE is one of two or more UEs intended to receive a second sidelink transmission. The first UE transmits, to the two or more UEs, the second sidelink transmission during a portion of the first COT based on COT sharing. The COT sharing is in response to determining the second UE is one of the two or more UEs intended to receive the second sidelink transmission.

摘要： Aspects presented herein may improve the accuracy and/or the efficiency of HARQ feedback for a UE communicating with a base station or multiple TRPs using multiple antenna panels. In one aspect, an apparatus receives DCI scheduling a PDSCH to be received by a first plurality of panels and indicating a second plurality of PUCCH repetitions for providing ACK/NACK feedback. The apparatus receives the PDSCH through the first plurality of panels. The apparatus transmits ACK/NACK feedback in the indicated second plurality of PUCCH repetitions based on the received PDSCH.
