摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive first control signaling indicating a first network operation sequence associated with a first component carrier, the first network operation sequence including a first set of time intervals corresponding to a first set of network operation modes for the first component carrier. The UE may additionally receive second control signaling indicating a second network operation sequence associated with a second component carrier, the second network operation sequence including a second set of time intervals corresponding to a second set of network operation modes for the second component carrier. The UE may then communicate via the first component carrier in accordance with the first network operation sequence, and communicate via the second component carrier in accordance with the second network operation sequence.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit channel state information (CSI) that is based on an estimated cross link interference (CLI) at the UE. For example, a network entity may indicate, to a first UE and a second UE, transmission parameters of a multi-port CLI-reference signal (CLI-RS) that is associated with estimation of CLI channel between the first UE and the second UE. The network entity may indicate, to the first UE, one or more precoding parameters associated with uplink precoding at the second UE. The second UE may transmit the multi-port CLI-RS to the first UE, and the network entity may transmit a CSI-reference signal (CSI-RS) to the first UE. The first UE may transmit a report that includes CSI based on the multi-port CLI-RS, the CSI-RS, and the one or more precoding parameters.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit channel state information (CSI) that is based on a precoded cross link interference (CLI) channel at the UE. For example, a network entity may transmit a control message to a first UE that indicates a reporting configuration for indicating CSI associated with a channel between the first UE and the network entity. The first UE may generate the CSI based on a precoded CLI channel at the first UE associated with at least one uplink transmission associated with a second UE, where the precoded CLI channel is generated using at least one estimated CLI channel associated with the at least one uplink transmission and at least one candidate precoding matrix associated with the second UE. In accordance with the reporting configuration, the first UE may transmit the CSI to the network entity.

摘要： Methods, systems, and devices for wireless communications are described for cell access techniques in carrier aggregation configurations in which one or more carriers do not provide discovery signals such as synchronization signal block (SSB) transmissions. A UE may be configured with an anchor carrier on which SSBs are transmitted, and one or more non-anchor carriers on which SSBs are not transmitted. A single cell barring indication may be provided for the anchor carrier, in which case the UE may follow cell barring indications for associated non-anchor carriers. In other cases, separate cell barring indications may be provided for one or more anchor carriers and one or more non-anchor carriers.

摘要： Methods, systems, and devices for wireless communications are described. In one aspect, a UE may report channel state feedback (CSF) to a network entity based on channel state information (CSI) measurements and CLI measurements. In another aspect, a UE may explicitly report CLI measurements to a network entity. In yet another aspect, a UE may report a signal-to-interference-plus-noise ratio (SINR) to a network entity based on CLI measurements, and the network entity may trigger the UE to perform further CLI measurements on signals received from other UEs based on the SINR. In yet another aspect, a UE may generate a report using CLI measurements based on whether the UE is allocated enough time to generate and transmit the report. In yet another aspect, a UE may identify a suitable priority for reporting CLI to a network entity.

摘要： Certain aspects of the present disclosure provide techniques for autonomous uplink (UL) cancellation. A method that may be performed by a user equipment (UE) includes receiving one or more configurations scheduling a communication with at least one base station (BS), wherein the one or more configurations schedule a UL transmission and a DL transmission such that the UL transmission and the DL transmission overlap in a time domain, determining whether to cancel at least a portion of the UL transmission based on one or more conditions associated with the UL transmission or the DL transmission, wherein the determination of whether to cancel at least the portion of the UL transmission is in response to the UL transmission and the DL transmission overlapping in the time domain, and performing the communication based on the determination, in accordance with aspects of the present disclosure.

摘要： Aspects described herein relate to receiving, from a base station on a first subband of an unlicensed frequency band, control information that includes a resource allocation of an uplink transmission associated with the first UE and a demodulation reference signal (DMRS) configuration of a downlink transmission associated with a second UE. The apparatus also may obtain one or more measurements of a DMRS within channel activity on a second subband of the unlicensed frequency band using a listen-before-talk (LBT) operation based on the DMRS configuration. The apparatus also may determine whether the channel activity corresponds to the downlink transmission associated with the second UE based on the one or more measurements of the DMRS within the channel activity. The apparatus also may communicate, with the base station on the second subband, the uplink transmission when the channel activity corresponds to the downlink transmission associated with the second UE.

摘要： Aspects of the disclosure relate to a downlink (DL) resource allocation feature in a wireless communication system, configured to address an issue that may arise in a sub-band full-duplex (SBFD) carrier (also sometimes called a flexible duplex carrier). For example, on an SBFD carrier, a slot may have a format where an uplink (UL) portion of the carrier is between two DL portions of the carrier. In a case where a scheduler operating in a New Radio (NR) network utilizes DL resource allocation of a particular type, it may arise that a portion of the DL allocation falls in the UL portion of the carrier. Accordingly, a scheduled entity may add the UL portion of the carrier to a set of resources that are indicated as not available for DL transmission. Other aspects, embodiments, and features are also claimed and described.

摘要： A UE may receive DCI from a first TRP scheduling a transmission of a TB from the first TRP and a second TRP. The UE may receive, from the first TRP a first set of CBGs of the TB in a first set of resources. The UE may receive, from the second TRP a second set of CBGs of the TB in a second set of resources that is different than the first set of resources. The first set of CBGs may be received based on a first MCS and the second set of CBGs may be received based on a second MCS. The UE may transmit, in a full-duplex mode, a message to the first TRP. The transmission to the first TRP may overlap in time with the reception from the first TRP. Accordingly, the first MCS may be lower than the second MCS.
