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 communications are described in which a base station may identify a null space matrix that lies within a null space of an effective channel matrix for communications between the base station and a user equipment (UE). An indication of the null space matrix may be provided to the UE, and the null space matrix used to determine modifications to a precoding matrix. The base station and UE may determine a redistribution matrix that provides a reduced variance of transmission powers for a number of transmission channels, where a product of the null space matrix and the redistribution matrix may be computed and added to the precoding matrix to generate a modified precoding matrix. The modified precoding matrix may be used to generate the communications from the base station and UE with reduced power variance across channels.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support various extended reality (XR) applications. In some examples of XR applications, features from the real and virtual environments may be overlaid and displayed to a user for consumption via the UE. To avoid visual conflicts, such as misaligning objects from the real and virtual environments, and other visual conflicts, the UE may generate and send pose information to a network (e.g., a server hosting the XR application). The UE may be configured to manage transmission of pose information to the network, which may result in reduced power consumption. For example, the UE may determine a downlink burst occasion for the XR application, generate pose information associated with the UE and the XR application, and transmit the pose information only during the downlink burst occasion.

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 a transmitter (e.g., a user equipment (UE) or base station) and receiver (e.g., a UE or base station) to transmit and receive data packets that are encoded according to an outer coding technique. The outer coding technique may provide for data bits and parity bits to be included in a single physical layer transmission. In some cases, data packets (e.g., data bits) may be segmented into multiple subpackets, and coding may be performed across different subpackets of different data packets (e.g., in a diagonal coding pattern). In some examples, each transmission in the physical layer may contain both data subpackets and parity subpackets, which may balance an input and an output load of a buffer (e.g., a layer two (L2) decoding buffer at the receiver) during decoding.

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: Certain aspects of the present disclosure provide techniques for mapping time domain positions for a demodulation reference signal (DMRS). A method that may be performed by a user equipment (UE) includes identifying time domain positions for a DMRS to be transmitted with a transport block (TB) sent across multiple slots and transmitting the TB across the multiple slots with the DMRS in the time domain positions.

Abstract: A user equipment for wireless communications includes a memory configured to store a peak reduction tone (PRT) table and a processor configured to retrieve a plurality of PRT sequences from the PRT table. The plurality of PRT sequences includes a first PRT sequence based upon a first data rate and a second PRT sequence based upon a second data rate. The second data rate is larger than the first data rate, and the second PRT sequence is a subset of the first PRT sequence. The user equipment also includes a power amplifier operable to transmit data with the first PRT sequence according to the first data rate or with the second PRT sequence according to the second data rate.

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.
