Abstract: Apparatus, methods, and computer-readable media for facilitating duplex mode per uplink control channel resource are disclosed herein. An example method for wireless communication at a user equipment includes receiving a physical uplink control channel (PUCCH) resource configuration from a base station, the PUCCH resource configuration indicating an uplink beam for transmitting an uplink transmission. The example method also includes identifying a downlink beam paired with the uplink beam for transmitting the uplink transmission, the paired downlink beam for full-duplex reception of a downlink transmission from the base station that overlaps in time with transmission of the uplink transmission. Additionally, the example method includes performing full-duplex communication with the base station by transmitting the uplink transmission using the uplink beam while receiving the downlink transmission using the paired downlink beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a control resource set (CORESET) is not configured for an active downlink bandwidth part of a component carrier (CC) of the UE. The UE may determine that a transmission configuration indication (TCI) state is not activated for a physical downlink shared channel (PDSCH) of the active downlink bandwidth part of the CC. The UE may determine a default spatial relation for an uplink control channel or uplink signal for the CC based at least in part on determining that the CORESET is not configured for the active downlink bandwidth part of the CC and that the TCI state is not activated for the PDSCH of the active downlink bandwidth part of the CC. Numerous other aspects are provided.

Abstract: Aspects relate to mechanisms for sidelink reservation across frequency bands. In some examples, a sidelink device may be configured to communicate over a first frequency band (e.g., a sub-6 gigahertz frequency band) and a second frequency band (e.g., a millimeter wave frequency band) with one or more other sidelink devices. The sidelink device may further be configured to perform cross-link resource reservation for a sidelink transmission in which a resource reservation message transmitted on the first frequency band indicates reserved resources within the second frequency band for the sidelink transmission. The sidelink device may then transmit sidelink control information (SCI) within a sidelink control channel on the second frequency band and user data traffic corresponding to the SCI within a sidelink data channel on the second frequency band.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink communication. A method that may be performed by a user equipment (UE) includes selecting a modulating and coding scheme (MCS) and a transmission power based on a configured dependency between one or more candidate MCSs and one or more candidate transmission powers, and transmitting, via a sidelink channel, one or more frames using the selected MCS and the selected transmission power.

Abstract: Aspects provide for autonomous adjustment of the uplink and downlink transmission timing in wireless communication networks. A scheduled entity (e.g., a user equipment (UE) or child integrated access backhaul (IAB) node) may observe a change in the downlink reception timing of downlink signals transmitted from a scheduling entity (e.g., a base station or parent IAB node). The scheduled entity may then autonomously adjust its uplink transmission timing to compensate for the change in downlink reception timing. In addition, the scheduled entity may further maintain the same downlink transmission timing irrespective of the change in downlink reception timing.

Abstract: Described are methods for interference detection and management in a millimeter wave communications system. A V2X communications system may support interference management procedures that comprise scheduling a system wide training interval in a transmission timeslot, suspending traffic transmissions on a link in the communications system during the training interval to perform training on the link, and resuming traffic transmissions on the link if interference is not detected during the training interval. Interference management procedures may also include receiving at a node, unique parameters transmitted from another node in a communication system during a discovery stage, determining whether interference will occur at the node based on the received unique parameters, and suspending transmissions to and from the node if it is determined interference will occur at the node.

Abstract: Methods, systems, and devices for wireless communications are described. To support adaptive quantization level selection in federated learning, a server may cause a base station to transmit an indication of a quantization level for a user equipment (UE) to use to compress gradient data output by a machine learning model. For example, the server may determine, for each UE of a set of UEs, a respective quantization level for respective gradient data that is output by a respective machine learning model at each UE. The server may transmit, to each UE via one or more base stations, first information for use as an input in the respective machine learning model and an indication of the respective quantization level. A UE may receive the first information and the indication and may transmit, to the server, compressed gradient data that is generated based on (e.g., using) the indicated quantization level.

Abstract: Wireless communications systems and methods related to handling link failures in a first cell and a second cell are provided. A wireless communication device can detect a first link failure associated with a first cell and can detect a second link failure associated with a second cell. Additionally, the wireless communication device can perform a link failure recovery procedure. This may include prioritizing a first link failure recovery for the first cell over a second link failure recovery for the second cell. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may identify that the UE is capable of performing up to a maximum quantity of antenna panel switches within a slot. For example, the UE may be capable of switching from operating one or more first antenna panels to operating one or more second antenna panels up to a maximum quantity of times within a slot. In some aspects, the UE may transmit an indication of the UE capability to a base station. The base station, based on receiving the indication of the UE capability, may transmit activation signaling indicating one or more antenna panel switches at the UE within a slot that is less than or equal to the maximum quantity of antenna panel switches per slot indicated by the UE capability.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to receive, from a second wireless device via a sidelink communication link, a sidelink control information (SCI) scheduling an uplink transmission from the first wireless device to the second wireless device. The first wireless device may then generate the uplink transmission based on the SCI. The first wireless device may then transit the uplink transmission to the second wireless device via the sidelink communication link in accordance with the SCI.
