Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify one or more radio frequency (RF) spectrum bands for full-duplex communications, and may signal an indication of the UE's capability to support full-duplex communications for each RF spectrum band. The UE may further receive one or more configurations for full-duplex communications, which, in some examples, may be based on the UE's indicated capabilities. As an example, the UE may identify a guard band configuration for full-duplex communications, where the guard band configuration may be based on one or more aspects of resources used for the full-duplex communications. In other cases, the UE may identify a transmission hopping or antenna switching configuration for full-duplex communications. In any case, the UE may communicate with a base station in accordance with the one or more configurations and the UE's capabilities.

An example base station may transmit, to a first user equipment (UE), an indication of a first transmit (Tx) power for one or more first DL transmissions to a first group of a plurality of groups. The first group may include the first UE. The first Tx power may have a first power level different from a second power level of a second Tx power for one or more second DL transmissions to a second group of the plurality of groups. Then, the base station may transmit, to the first UE, a first DL transmission of the one or more first DL transmissions using the first Tx power. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured with two sets of power control parameters may be signaled (e.g., via downlink control information (DCI)) as to which set of parameters to use for determining the transmission power on a sidelink channel. The UE may determine a transmit power for a sidelink message based on the indication included in the DCI. The base station may transmit the indication based on whether uplink or downlink communications are scheduled on resources that may overlap with resources used for transmission of the sidelink message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, control information that indicates at least two transmission configuration indicator (TCI) states. A first TCI state of the at least two TCI states is associated with a half duplex mode of the UE, and a second TCI state of the at least two TCI states is associated with a full duplex mode of the UE. The UE may further receive, from the base station, a downlink transmission according to at least one of the first TCI state or the second TCI state. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described for cross-link interference (CLI) measurement and estimation in one or more cells that are inactive or dormant. A user equipment (UE) operating in a first serving cell (e.g., a primary cell (PCell)) may measure one or more reference signals, with the measurements used to estimate one or more CLI measurements of one or more other cells (e.g., one or more secondary cells (SCells)). CLI estimates may be based on scaling factors associated with frequency locations of the PCell and SCell, may be based on a coupling loss estimate associated with different frequency bands, or combinations thereof.

Abstract: Wireless communication devices, systems, and methods related to downlink control information (DCI) designs for multi-component carrier scheduling are provided. For example, a method of wireless communication can include receiving a downlink control information (DCI) message having a DCI format, the DCI message scheduling a downlink data communication over a single component carrier or multiple component carriers; determining, based on the received DCI message, whether the downlink data communication is scheduled over the single component carrier or the multiple component carriers; and receiving, based on the determining, the downlink data communication over the single component carrier or the multiple component carriers.

Abstract: Methods, systems, and devices for wireless communication are described to support indication of a single frequency network (SFN) mode and associated parameters to a user equipment (UE), while the UE is operating in an idle mode. While operating in the idle mode, the UE may receive signaling from a transmission reception points (TRP), indicating that an SFN will be used for broadcast signaling received concurrently from multiple TRPs. Based on receiving the indication of the SFN, the UE may receive the broadcast signaling via a downlink control channel. For example, the UE may receive the broadcast signaling concurrently from a first TRP via a first beam and from a second TRP via a second beam, where the first and second beams may each be associated with a respective synchronization signal block (SSB).

Abstract: Aspects of the disclosure relate to downlink (DL) transmissions using various powers and assigning frequency resources based on the powers. An example base station may transmit, to a first user equipment (UE), an indication of a first transmit (Tx) power for a first DL transmission on a first downlink (DL) resource on a carrier, the first DL resource being at a first frequency. The first DL resource may be at a first frequency. The first Tx power may have a power level configured based on a difference between the first frequency for the first DL resource and an uplink (UL) frequency region of the carrier. Then, the base station may transmit the first DL transmission using the first frequency and the first Tx power. Other aspects, embodiments, and features are also claimed and described.
