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.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor for one or more downlink transmissions from a base station based at least in part on a grant identifying resources for the one or more downlink transmissions. The UE may determine feedback information for each of the one or more downlink transmissions based at least in part on the monitoring. The UE may identify, based at least in part on the monitoring, one or more duplexing parameters to be requested to the base station for subsequent communications between the UE and the base station, the one or more duplexing parameters pertaining to operation of the UE in at least one of a full duplex communications mode or a half duplex communications mode. The UE may transmit a feedback message indicating the feedback information and the one or more duplexing parameters to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may send signaling to multiple user equipments (UEs) indicating for the UEs to switch to a radio frequency bandwidth. The UEs may operate according to a reduced set of communication operations in accordance with the radio frequency bandwidth. For example, the UEs may refrain from monitoring one or more channels, may not transmit on one or more channels, or the like. The UEs may switch out of the radio frequency bandwidth based on a trigger event, such as a timer expiring, receiving an indication in a downlink control information (DCI) message, or the like.

Abstract: Methods, systems, and devices for wireless communications are described that provide for configuration of one or more parameter tables that provide mapping between channel measurements and a channel quality indicator (CQI), one or more tables that provide mapping between a modulation and coding scheme (MCS) index and a modulation order and coding rate, or any combinations thereof. A base station may provide configuration information to a user equipment (UE) that indicates a table size for one or more CQI or MCS tables, and a number of bits that are to be transmitted in control information to indicate an index value for the CQI and/or MCS tables. Alternatively, an existing CQI or MCS table may have entries that are modified based on a modulation order that is supported by the UE, and the base station may provide configuration information that indicates the modified entries.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a control message that includes an identification of a set of protection levels corresponding to different degrees of physical layer security for securing communications between the UE and the base station. The base station may transmit, to the UE, an indication of an identified protection level of the set of protection levels to be used by the UE for securing the communications between the UE and the base station. The UE may communicate with the base station in accordance with the identified protection level.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control signal scheduling the UE to receive a downlink message from the base station using a set of time and frequency resources. The UE may identify an aggressor UE attempting to receive uplink communications, downlink communications, or both, transmitted between the UE and the base station and determine a transmit power for transmitting a jamming signal to the aggressor UE during the set of time and frequency resources. The UE may apply a jamming signal power scheme to the jamming signal by either using the determined transmit power or adjusting the determined transmit power in accordance with the jamming signal power scheme.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a set of transmission time intervals (TTIs) including at least one TTI to be used for full-duplex communications. The UE may receive control signaling that indicates a frequency domain resource allocation (FDRA) for a physical uplink channel transmission in a first TTI. The UE may determine whether a second TTI is available for transmitting one or more repetitions of the physical uplink channel transmission based on comparing the FDRA to resources allocated to the second TTI. For example, the second TTI may be available if one or more physical resource blocks (PRBs) of the FDRA are non-overlapping in a frequency domain with downlink resources allocated to the second TTI. The UE may transmit the one or more repetitions in the second TTI based on the second TTI being available.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a grant that schedules multiple repetitions of a communication. A first repetition, of the multiple repetitions of the communication, is to be transmitted or received in a time domain interval configured for one of half-duplex communication or full-duplex communication. A repetition, of the multiple repetitions of the communication, is to be transmitted or received in another time domain interval configured for the other of half-duplex communication or full-duplex communication. The UE may transmit or receive one or more of the multiple repetitions of the communication based at least in part on the configuration of the time domain interval of the first repetition. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication that one or more reference signals correspond to multiple beam configurations. The UE may be configurated to communicate with multiple transmission reception points. The UE may receive a second indication of a first quasi co-location (QCL) type and a second QCL type based on receiving the first indication. The first QCL type may be associated with a first beam configuration corresponding to a first transmission reception point, and the second QCL type may be associated with a second beam configuration corresponding to a second transmission reception point. The UE may determine whether the multiple transmission reception points are using a pre-compensation scheme based on the first and second QCL types. The UE may receive one or more reference signals from the multiple transmission reception points based on the determining.
