Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of whether a rate match pattern indicates a location of an uplink sub-band and at least one guard band for sub-band full duplex communication, the rate match pattern identifying resources that are to be avoided for downlink data communication. The UE may communicate according to the rate match pattern based at least in part on the indication. Numerous other aspects are described.

Indicating sub-band locations for sub-band full duplex communication

Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) and a network entity may support one or more signaling-based mechanisms according to which the network entity may inform the UE of which time and frequency resources may be used for full-duplex communication. The network entity transmit a first message to configure multiple resource block (RB) sets for the UE, where each RB set is associated with unique identifying information. To inform the UE of which time and frequency resources may be used for full-duplex communication, the network entity may transmit a second message that indicates one or more slot formats on a per RB set basis. As such, the network entity may schedule the UE for full-duplex communication in accordance with indicating that overlapping symbols of a first RB set and a second RB set are allocated for uplink and downlink, respectively.

Techniques for slot format configuration per resource block set for subband full-duplex operation

A method, a computer-readable medium, and an apparatus are provided for wireless communication including random access between a base station and a user equipment (UE). The UE transmits a beam report comprising beam measurement information to the base station and transmits a first random access message to the base station for reception using one or more beams based on a random access measurement that is different than the beam measurement information comprised in the beam report. The UE monitors for a second random access message from the base station using multiple beams, the beams being selected based on the beam report.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for cross-link interference (CLI) measurement in subband full-duplex (SBFD) operation. In some aspects, a first user equipment (UE) may measure CLI from a second UE during a SBFD symbol in one or more uplink subbands or in one or more downlink subbands, or in a combination thereof. The first UE and a network entity may support one or more prioritization rules associated with one or both of a capability of the first UE and potential scheduling conflicts at the first UE during the SBFD symbol. In some aspects, the first UE may measure a CLI reference signal transmitted by the second UE in one or more uplink subbands and in one or more downlink subbands allocated to the first UE to obtain an inter-subband CLI measurement and an intra-subband CLI measurement.

Cross-link interference (CLI) measurement in subband full-duplex (SBFD) operation

A UE receives information indicating a set of slots or symbols for a subband full duplex (SBFD) operation. The UE also receives a configuration of an SBFD format including at least a first subband for uplink communication and a second subband for downlink communication. The UE further receives an indication that indicates for the UE to update the SBFD format for at least a subset of the set of slots or symbols.

Signaling to indicate flexible uplink or downlink subbands

Aspects of the present disclosure provide techniques for sub-band conversion or cancellation for dynamic scheduling of sub-band full duplex (SBFD) operations between the base station and UEs. The capability to communicate via simultaneous UL and DL transmissions through dynamic scheduling allows for increased uplink duty cycle leading to latency reduction (e.g., it is possible to receive DL signal in an UL only slots, which can enable latency savings) and improved uplink coverage. Additionally enabling flexible and dynamic UL and DL resource adaptation in accordance with techniques of the present disclosure also provide enhanced system capacity, resource utilization, and spectrum efficiency.

Methods and apparatus for dynamic scheduling of sub-band full duplex communications

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling (e.g., from a network entity) indicating a CLI measurement resource and an associated transmission configuration indicator (TCI) state. The UE may generate and transmit a CLI report to the network entity using the CLI measurement resource and the beam associated with the indicated TCI state. In some cases, the control signaling may indicate to use the same TCI state as another dedicated downlink channel configured for the UE. In some cases, the control signaling may indicate a unified TCI state to apply for the CLI measurement. In some cases, a UE may be configured to communicate with multiple transmission and reception points (TRPs). The TCI state to apply to the CLI measurement may be based on the TRP scheduling the CLI measurement.

Unified transmission configuration indicator state indication for cross-link interference measurement

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.
