Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. Because the local antennas and auxiliary antennas may have different capabilities (e.g., due to different power or other constraints), the first device may generate first uplink signals for transmission using the local antennas differently from second uplink signals for transmission using the auxiliary antennas. The first device may transmit the first uplink signals to the base station using the local antennas and transmit the second uplink signals to the second device for transmission to the base station using the auxiliary antennas based on different configurations.

Abstract: Methods, systems, and devices for wireless communication are described. A network node may determine a first time location associated with a peak in data traffic for multiple devices in communication with a communications network including the network node. The network node may determine a second time location for the peak in the data traffic for a subset of the devices based on a threshold for an overall peak in data traffic for the multiple devices. The network node may transmit a signal that indicates the second time location for the peak in the data traffic for the subset of devices. The network node may communicate the data with the subset of devices based on the signal indicating the second time location.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support enhanced beam management using extended reality (XR) perception data. In a first aspect, a method of wireless communication includes establishing a communication connection between a user equipment (UE) and a serving base station using a current serving beam selected by the UE from a plurality of available beams paired with a serving base station beam. The method further includes obtaining, perception information from one or more extended reality sensors associated with the UE and determining, in response to detection of UE movement, a transpositional representation of the movement using the perception information. The UE may then select a new serving beam in accordance with the transpositional representation. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described for user equipment (UE) indication of uplink scheduling information to a base station. The uplink scheduling information may provide information on a periodic traffic pattern, such as for periodic extended reality (XR) data flows. The uplink scheduling information may provide uplink assistance information (UAI) to a base station to assist the base station with providing uplink resources that efficiently serve an XR session. The UAI may indicate one or more of a periodicity of uplink traffic, an offset between uplink traffic and a packet arrival, a data size for uplink traffic for each time period associated with the XR session, a request to enable uplink transmission skipping, or any combinations thereof. A base station may provide one or more dynamic grants, configured grants, or proactive grants to a UE based on the uplink scheduling information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to full-duplex cooperative communication by a first device tethered with a second device communicating with a third device. With the tether, one device between the first device and the second device is designated or selected as a transmitter, and the other device as a receiver. In full-duplex operation, the transmitter may transmit outgoing data concurrent to the receiver receiving incoming data. In an example, one of the first and second devices may have a modem that is used to control the full-duplex communication. The modem controls both transmission and reception. In another example, both devices may have a modem. Each modem may assume responsibility for part of the full-duplex communication by performing some processing before either shipping received data, or transmitting outgoing data. The amount of processing may be split at a link layer. Interference cancellation may mitigate interference from full-duplex operation.

Abstract: Methods, systems, and devices for wireless communications are described. Some methods include receiving an indication of a traffic flow to be served by a wireless communication system, determining scheduling information for the traffic flow based on the indication, wherein the scheduling information comprises one or more of a time offset, a reliability, and a minimum throughput of delivery of data traffic for the flow, and transmitting the scheduling information in response to the indication. Some methods include determining delta time offset information relative to one or more existing time offsets of packet arrivals of one or more traffic flows for scheduling transmissions of a first traffic flow in the wireless communication system, and transmitting the delta time offset information to a node of the first traffic flow for scheduling transmissions of the first traffic flow in the wireless communication system. Other aspects and features are also claimed and described.
