Some aspects of the disclosure are related to channel state information (CSI) reporting for one or both of a private message (p-message) or a common message (c-message). In some aspects, a user equipment (UE) may receive a signal that includes a p-message associated with the UE and a c-message associated with the UE and at least one other UE. The UE may transmit a measurement report that indicates one or both of first CSI associated with the p-message or second CSI associated with the c-message.

Channel state information (CSI) reporting for one or both of a private message (p-message) or a common message (c-message)

Methods, systems, and devices for wireless communications are described that provide for mitigation of interference related to full-duplex communications for random access channel (RACH) initial access procedures in shared radio frequency spectrum. A user equipment (UE) may send different RACH preambles subsequent to a channel access procedure, based on whether full-duplex communications or half-duplex communications are being used at a corresponding network entity. The different RACH preambles may include a longer RACH preamble that is used when full-duplex is present, and a shorter RACH preamble that is used when full-duplex is not present. The shorter or longer RACH preamble may be used, for example, based at least in part on an open-loop transmit power for the RACH procedure, a RACH occasion configuration that provides different preamble lengths for different RACH occasions, a full-duplexing type that is being used, or any combinations thereof.

Random access preamble techniques in full-duplex wireless communications

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first configuration of a first bandwidth part (BWP) associated with a primary cell of a communication link. The UE may receive an indication of a second configuration of a second BWP associated with a secondary cell, the second configuration of the second BWP being associated with refraining from measuring of channel state information reference signals (CSI-RSs). Numerous other aspects are described.

Techniques for bandwidth part configuration associated with channel state information reference signal measurement

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for bandwidth part (BWP) dynamic adaptation in accordance with an energy level at a user equipment (UE). In some systems, the UE may implement techniques for power savings by operating according to a narrower BWP in accordance with an energy level at the UE. In some implementations, the UE may reduce the bandwidth size of the active BWP if the UE energy level satisfies a threshold. The UE may transmit signaling to the network indicating that the bandwidth size of the active BWP is reduced. Additionally, or alternatively, the UE may fall back to a default BWP if the UE energy level satisfies a threshold. For example, the UE may fall back to the default BWP prior to expiration of a timer configured to trigger the UE to fall back to the default BWP.

Bandwidth part (BWP) dynamic adaptation in accordance with an energy level at a user equipment (UE)

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.

Cross-link interference reporting configuration and payload design

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control information indicative of a set of time division duplexing (TDD) patterns. A first dedicated TDD pattern of the set of TDD patterns may be dedicated for TDD communications between the UE and a first transmission and reception point (TRP) from a set of multiple TRPs associated with a network entity. The UE may determine at least a second dedicated TDD pattern for TDD communications between the UE and at least a second TRP from the set of multiple TRPs based on the set of TDD patterns. The UE may communicate with the network entity via at least one of the first TRP or the second TRP in accordance with the first dedicated TDD pattern, the second dedicated TDD pattern, or both.

Techniques for implementing full-duplex communications via multiple transmission and reception points

Apparatus, methods, and computer program products for wireless communication are provided. An example method may include transmitting, to a second network entity, a repetition configuration associated with a first PSSCH transmission and a second PSSCH transmission, where the repetition configuration includes information indicative of a frequency hopping pattern associated with the first PSSCH transmission and the second PSSCH transmission. The example method may further include transmitting, to the second network entity, the first PSSCH transmission including a first instance of sidelink information based on the frequency hopping pattern. The example method may further include transmitting, to the second network entity, the second PSSCH transmission including a second instance of the sidelink information based on the frequency hopping pattern.

Transmission across partitioned resource pools

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive transmission configuration indication (TCI) state restriction information indicating that a TCI state associated with sub-band full-duplex (SBFD) communications is restricted for downlink communications. The UE may communicate in accordance with the TCI state restriction information. Numerous other aspects are described.

Transmission configuration indication state restriction for sub-band full-duplex communications

A user equipment (UE) may be configured to transmit or receive reference signals in flexible symbols that are indicated as used for full duplex communications. The UE may transmit or receive reference signals over frequency resources of a symbol indicated as a flexible symbol, which may configured for uplink or downlink communications, that is also configured as full duplex, which may include frequency resources for both uplink and downlink communications. The UE may determine whether or how to transmit one or more reference signals in a flexible symbol based on at least one of the bandwidth of the uplink resources or the bandwidth of the downlink resources, the frequency positions of the reference signals, or other criteria. A base station may be configured to similarly transmit or receive reference signals in flexible symbols that are indicated as used for full duplex communications.
