摘要： A method of wireless communication by a user equipment (UE) includes receiving, from a base station, a downlink demodulation reference signal (DMRS) generated from a downlink DMRS configuration. The method also includes transmitting, to the base station, an uplink DMRS generated from an uplink DMRS configuration. A value of one or more parameter(s) of the uplink DMRS configuration differs from a value of the parameter(s) of the downlink DMRS configuration. A method of wireless communication by a base station includes transmitting, to a user equipment (UE), a downlink demodulation reference signal (DMRS) generated from a downlink DMRS configuration. The method also includes receiving, from the UE, an uplink DMRS generated from an uplink DMRS configuration. A value of one or more parameter(s) of the uplink DMRS configuration differs from a second value of the parameter(s) of the downlink DMRS configuration.

摘要： Apparatus, methods, and computer program products for SSB adaptive power transmission are provided. An example method includes performing a measurement of a medium for transmission of an SSB. The example method further includes transmitting, based on the measurement, the SSB at an SSB candidate position from a set of SSB candidate positions, wherein transmitting the SSB comprises transmitting using a first transmission power level if the measurement is within a first range and transmitting using a second transmission power level if the measurement is within a second range, the second transmission power level being lower than the first transmission power level.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating one or more communication patterns from a base station. The one or more communication patterns may indicate to the UE to adjust one or more parameters for transmitting an uplink communication during a set of time resources, a set of beams, a set of ports, or any combination thereof. During the resources indicated in the one or more communication patterns, the base station may estimate a cross-link interference channel between the base station and a second base station. The one or more communication patterns may indicate a hopping pattern for each subband of a bandwidth part. The base station may configure the UE with a timing advance based on the message.

摘要： Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive control signaling indicating a configuration for performing channel sensing. The configuration may include one or more parameters corresponding to a processing time associated with the channel sensing. The UE may adjust the processing time associated with the channel sensing based on the one or more parameters and a full duplex capability of the first UE. The UE may transmit, using a first set of resources, a sidelink message based on the adjusted processing time. In some examples, the UE may transmit a first data message associated with a first priority level and perform channel sensing for a second data message associated with a second priority level that is higher than the first priority level. The UE may drop the first data message, skip an interference cancellation, or a combination 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： 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.
