  • Publication number: 20240365290
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a first frequency resource allocation associated with a first slot type and, in some cases, a second frequency resource allocation associated with a second slot type for a configured grant (CG). The CG may be associated with half-duplex (HD) slots and subband full-duplex (SBFD) slots. The UE may transmit an uplink message to a network entity via a first set of one or more slots associated with the CG using the first frequency allocation based on the first set of one or more slots being of the first slot type. The UE may cancel a use of the first frequency allocation for transmitting the PUSCH via a second set of one or more slots if the second set of slots is of the second slot type.

  • Publication number: 20240364563
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may precode sounding reference signals using an interference covariance matrix to report channel quality information to a base station. For example, a UE may receive an indication of a future time from a base station. The future time may correspond to a future time for which the UE may predict an interference covariance matrix. In some cases, based on receiving the indication, the UE may monitor for interference in one or more interference measurement resources. In some examples, the UE may then determine the predicted interference covariance matrix and may transmit a sounding reference signal to the base station. The sounding reference signal may be precoded based on the predicted interference covariance matrix. In some cases, the UE may receive a downlink signal from the base station at the future time or at a second time.

  • Patent number: 12133241
    Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.

  • Patent number: 12133243
    Abstract: 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.

  • Publication number: 20240357393
    Abstract: Aspects are provided which allow a base station to provide CSI report configurations and a UE to provide CSI reports in response to such configurations which account for a power savings mode of the base station. While in the power savings mode, the base station may deactivate one or more of its antenna panels or sub-panels to reduce energy expenditure, for example, while performing dynamic antenna port adaptation. To account for this antenna port deactivation, the base station may send a CSI report configuration to a UE including one or more measurement resource sets associated with the power savings mode. The UE may obtain the CSI report configuration and send a CSI report to the base station in response to a CSI measurement in the one or more measurement resource sets.

  • Patent number: 12120049
    Abstract: Aspects relate to sounding reference signal (SRS) time-domain bundling. Phase continuity may be maintained across SRS transmissions over multiple SRS occasions to enable a receiver to jointly process these SRS transmissions. In some examples, a user equipment may expect to be configured with SRS transmissions over multiple SRS occasions where SRS configurations for different SRS transmissions over different SRS occasions specify the same parameters. For example, a first SRS configuration for a first SRS transmission over a first SRS occasion may specify a first set of spatial relation information. In addition, a second SRS configuration for a second SRS transmission over a second SRS occasion may specify that same first set of spatial relation information. In this way, phase continuity may be maintained between the first SRS transmission over the first SRS occasion and the second SRS transmission over the second SRS occasion.
