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. 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： 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.

摘要： Methods, systems, and devices for wireless communications are described for cross-link interference (CLI) measurement and estimation in one or more cells that are inactive or dormant. A user equipment (UE) operating in a first serving cell (e.g., a primary cell (PCell)) may measure one or more reference signals, with the measurements used to estimate one or more CLI measurements of one or more other cells (e.g., one or more secondary cells (SCells)). CLI estimates may be based on scaling factors associated with frequency locations of the PCell and SCell, may be based on a coupling loss estimate associated with different frequency bands, or combinations thereof.

摘要： Systems, methods, and devices for wireless communication that support mechanisms signaling non-linearities to a victim user equipment (UE) for interference cancellation in a wireless communication system. A victim UE may experience interference from an uplink transmission by an aggressor UE to a base station. The victim UE may obtain a power amplifier model associated with the aggressor UE. The power amplifier may include a non-linearity model of a power amplifier of the aggressor UE causing the interference on the victim UE. The power amplifier model obtained by the victim UE may be dependent on various parameters, such as a transmit power used by the aggressor UE to transmit the uplink transmission causing the interference. Based on the aggressor UE transmit power, the victim UE may select parameters for power amplifier model and may estimate the interference caused by the uplink transmission for interference cancellation.

摘要： Certain aspects of the present disclosure provide techniques for enhancing sidelink resource utilization for a user equipment (UE) that supports full duplex (FD) communications. For example, an FD UE may receive incoming sidelink communication over a first set of resources and, in FD mode, simultaneously transmit another sidelink communication over the same first set of resources. According to aspects of the present disclosure, the potential interference between the two sidelink communications will be mitigated or reduced, such as by having the FD UE negotiate with other sidelink UEs over transmission power levels and related aspects, such as beam coordination and/or resource subset designation, or the like.

摘要： Methods, systems, and devices for wireless communication are described to estimate interference for concurrent uplink and downlink communications based on an indication of one or more one or more characteristics of an interfering uplink signal communicated between a base station and a second user equipment (UE). The base station or the second UE may transmit, to a first UE, an indication of one or more characteristics of an uplink signal, such as a baseband of the uplink signal or one or more parameters of the uplink signal. The first UE may use the characteristic(s) of the uplink signal to estimate the baseband of the uplink signal and cancel interference associated with the uplink signal. For example, the first UE may use the baseband signal to estimate the interference and may subtract the estimated interference from a downlink signal received at the first UE.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that indicates a configuration for subband full duplex (SBFD) slots and a random access channel (RACH) configuration for SBFD slots. The UE may transmit at least one instance of a RACH message in an uplink subband of an SBFD slot in accordance with the RACH configuration. The RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across an SBFD slot and an uplink slot. The RACH configuration may map synchronization signal blocks (SSB)s to RACH occasions in the uplink subband of the SBFD slot. In some examples, the SSBs may be mapped across multiple (e.g., consecutive) SBFD slots. In some cases, the RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across multiple SBFD slots.

摘要： This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for collision handling. A first network node receives a first allocation of first resources at a first time and receives a second allocation of second resources at a second time, wherein the first time is before the second time, wherein one or more of the first resources overlap in a time domain and a frequency domain with one or more of the second resources, and wherein the first resources are uplink resources and the second resources are downlink resources or the first resources are downlink resources and the second resources are uplink resources. The first network node adjusts for the overlap in the time domain and the frequency domain between the first allocation of first resources and the second allocation of second resources.
