Certain aspects of the present disclosure provide techniques for guard period configuration between subband full duplex and half duplex symbols and slots. An example method that may be performed at a user equipment (UE) includes obtaining an indication of a guard period during which a cell in which the UE is communicating will switch between subband full duplex (SBFD) communications and half duplex (HD) communications; and performing one or more actions during the guard period, in accordance with the indication.

Guard period configuration between subband full duplex and half duplex symbols and slots

Certain aspects of the present disclosure provide techniques for wireless communication by a first network entity, comprising obtaining a first configuration for transmission of measurement reference signals (RS) by the first network entity, wherein the first configuration is adjusted based on information regarding one or more second configurations for transmission of measurement RS by one or more second network entities, and participating in a cross link interference (CLI) measurement procedure, in accordance with the first configuration.

Multiple victim/aggressor collision avoidance

Methods, systems, and devices for wireless communication are described. In a wireless communication system, a first wireless node may transmit a configuration message indicating one or more spatial configurations for communicating with a second wireless node. A spatial configuration may include one or more different sets of spatial parameters for half-duplex communications and full-duplex communications between the wireless nodes. In some examples, the first wireless node may select a first set of spatial parameters for half-duplex communications or a second set of spatial parameters for full-duplex communications based on an explicit indication or a resource configuration. The wireless nodes may perform half- or full-duplex communications using the first or second set of spatial parameters, respectively, in accordance with the configuration message.

Spatial parameters for half-duplex and full-duplex communications

Apparatus, methods, and computer program products for using spectrum sensing and supporting FD operations are provided. An example method may include performing a spectrum sensing based on a set of resources or a configuration to acquire information about at least one of FD operation or CLI associated with one or more cells of a base station during initial access. The example method may further include selecting a RO or a cell of the one or more cells based on the acquired information about the at least one of the FD operation or the CLI.

Spectrum sensing during initial access to a full-duplex cell

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive, from a user equipment (UE), a cross-link interference (CLI) report. The network node may transmit, to a second network node and based at least in part on the CLI report, CLI information indicating CLI associated with the UE. Numerous other aspects are described.

Cross-link interference information exchange

Methods, systems, and devices for wireless communications are described. Example wireless communications systems may implement control signaling configuring a user equipment (UE) to communicate in a subband full-duplex (SBFD) mode. An SBFD mode may include a non-contiguous bandwidth part (BWP), and control signaling may indicate the resource blocks (RB)s included in the non-contiguous BWP. In some cases, the non-contiguous BWP may be for communications between the UE and the network in one communications direction (e.g., uplink or downlink), and another BWP may be configured for communications between the UE and the network in the other communications direction. The non-contiguous BWP may include two subbands, and the other BWP may be non-overlapping with (e.g., positioned between) the two subbands in the frequency domain. The network may configure a BWP time domain switching pattern (e.g., switching between SBFD and half-duplex modes according to a BWP time domain switching pattern).

Non-contiguous resource blocks for bandwidth part configuration

Certain aspects of the present disclosure provide techniques for user equipment-based autonomous self-interference measurement. An example method includes transmitting at least one uplink (UL) transmission using at least one UL transmit beam, performing self-interference measurements using at least one downlink (DL) receive beam to measure, for full duplex operation, self-interference associated with the at least one UL transmission transmitted using the at least one UL transmit beam, and transmitting a measurement report indicating the measured self-interference associated with the at least one UL transmission transmitted using the at least one UL transmit beam.

Techniques for autonomous self-interference measurements

Aspects of the present disclosure provide mechanisms for facilitating cross-link interference (CLI) measurement and reporting for mobile network entities using a common window configuration for communication of reference signals. The common window configuration may indicate a plurality of occasions within a respective window of each of one or more cycles for communicating one or more reference signals. A network entity (e.g., a mobile network entity or a stationary network entity) may utilize the common window configuration to receive a reference signal from another network entity within an occasion of the plurality of occasions in order to obtain a CLI measurement indicating the CLI between the network entities.

Reference signal window configuration for mobile network entities

Methods, systems, and devices for wireless communications are described. A first communication device may transmit a reference signal and an offset to a second communication device. The offset may be between a first beam associated with the reference signal and a second beam associated with a data signal. The second communication device may perform measurements on the reference signal and use such measurements, in conjunction with the offset, to determine a beam for the first communication device to transmit communications. The second communication device may transmit an interference message corresponding to the second beam. The first communication device may transmit communications via the second beam.

Techniques for indicating a synchronization signal block

Methods, systems, and devices for wireless communications are described. A first network node may receive, in a first time interval, interference signals from a second network node on a portion of uplink resources used by the first network node to receive from a first set of wireless devices served by the first network node in the first time interval. The first network node may transmit, to the second network node, an identifier associated with the second network node and an indication that the second network node is to modify transmission on downlink resources used by the second network node to transmit to a second set of wireless devices served by the second network node. Transmitting the indication that the second network node is to modify transmission on the downlink resources includes transmitting, to the second network node, a signal configured to indicate modifying the transmission on the downlink resources.

Aggressor network node determination to apply restriction rule

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a resource associated with a random access channel (RACH) message. The UE may receive an indication of whether the resource associated with the RACH message is permitted to be used for transmission of the RACH message, wherein the indication is included in a dynamic signaling communication. The UE may transmit the RACH message in accordance with the indication. Numerous other aspects are described.

Dynamic indication of a full duplex random access channel occasion

Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for configuring a network entity to transmit reference signals for cross-link interference (CLI) measurements, receive reference signals for CLI measurements, or report CLI measurements. A first network entity may transmit an indication to a second network entity of a configuration for transmitting reference signals for CLI measurements. The first network entity may also transmit an indication to a third network entity of a configuration for monitoring for or receiving the reference signals for CLI measurements, and the first network entity may transmit another indication to the third network entity of a configuration for reporting the CLI measurements. The second network entity may then transmit the reference signals, and the third network entity may receive the reference signals, perform CLI measurements on the reference signals, and report the CLI measurements.

Inter access network interference measurement and report configuration

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive information indicating a reference signal resource associated with detecting cross-link interference associated with transmitting a random access channel (RACH) message on full duplex resources. The first UE may transmit a RACH message on a selected RACH occasion, wherein the selected RACH occasion is selected based at least in part on whether a reference signal transmitted by a neighbor UE of the first UE has been detected in association with the selected RACH occasion. Numerous other aspects are described.

Cross-link interference mitigation for full-duplex random access

Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support priority based conflict resolution in full-duplex operations. In some cases, a wireless device may communicate one or more control messages scheduling a first message associated with a first transmission configuration indicator (TCI) state and scheduling a second message associated with a second TCI state, where at least a portion of the first message overlaps in time with the second message. In some cases, the wireless device may perform a conflict resolution procedure for the first message and the second message based on the first message at least partially overlapping in time with the second message and a conflict between the first TCI state and the second TCI state. Additionally, the wireless device may communicate at least the first message based on the conflict resolution procedure.

Priority based conflict resolution in full-duplex operations

Methods, systems, and devices for wireless communication are described. A communication device may receive control signaling indicating a first set of resources for random access channel (RACH) occasions (ROs) and a second set of resources for communicating one or more indications of interference (e.g., crosslink interference (CLI)) associated with the ROs. The communication device may receive a reference signal (e.g., a sounding reference signal (SRS)) over at least one resource of the second set of resources. The communication device may perform a RACH procedure during an RO. The RO may be associated with the at least one resource and may be based on a signal parameter associated with the received reference signal satisfying a threshold (e.g., reference signal strength indicator (RSSI)).
