Abstract: Methods, systems, and devices for wireless communications are described. One method may include monitoring, via one or more sensors of a first user equipment (UE), at least one of a thermal overload condition or an exposure condition associated with a first communication link between a first UE and a base station. Based on the monitoring, for example, the first UE may determine that at least one of the thermal overload condition or the exposure condition exceeds a corresponding predetermined switch threshold. Based on the determining, a second communication link may be established between the first UE and a second UE, where the second UE is configured to operate as a relay UE, for communications between the first UE and the base station via (in-part) the second communication link.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, to a user equipment, uplink beam management configuration information identifying an uplink beam management configuration or downlink beam management configuration information identifying a downlink beam management configuration, wherein the uplink beam management configuration is associated with the downlink beam management configuration. The base station may communicate with the user equipment in accordance with the uplink beam management configuration and the downlink beam management configuration based at least in part on transmitting the uplink beam management configuration or the downlink beam management configuration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a tone satisfying an impairment value. The UE may select configuration information for communicating with a base station based on the tone. The UE may selectively transmit a signal to the base station indicating the configuration information. The UE may receive a configuration signal from the base station indicating a reference signal tone pattern for communicating reference signals between the UE and the base station.

Abstract: Methods, systems, and devices for wireless communications are described in which spatial relations for one or more uplink reference signal transmissions, such as sounding reference signal (SRS) transmissions, may be configured and a particular spatial relation indicated in a medium access control (MAC) control element (CE). A base station may configure a pool of available spatial relations for use in SRS transmissions, and the MAC-CE may indicate which spatial relation of the set of available spatial relations is to be used. In other cases, the MAC-CE may provide all of the spatial relation information for an associated SRS transmission. The UE, responsive to receiving the MAC-CE, may transmit a SRS to the base station using the indicated spatial relation.

Abstract: Methods, systems, and devices for wireless communications are described for phase error estimation and correction with sub-symbol resolution. A transmitting device may precode symbols (e.g., phase tracking reference signal (PT-RS) symbols) using a discrete Fourier transform (DFT). The transmitting device may map the DFT-precoded symbols to sets of adjacent subcarriers of a wireless signal, and may map other symbols to other subcarriers of the wireless signal. A receiving device may receive the wireless signal and may compare time domain representations of the DFT-precoded symbols with time domain representations of known reference symbols. The receiving device may estimate a phase error with sub-symbol resolution in the time domain based at least in part on the comparison, and may apply a phase correction in either the time or frequency domain to the other symbols.

Abstract: A user equipment (UE) determines a beam failure of a default uplink beam for the UE. The UE transmits an uplink beam failure report in response to determining the beam failure of the default uplink beam, the uplink beam failure report indicating that a reported beam is the default uplink beam for the UE. A base station receives an uplink beam failure report from the UE and determines that a reported beam is a default uplink beam for the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless node (e.g., a vehicle mounted integrated access and backhaul (IAB) node) may aid in wireless communication between one or more wireless devices operating in a high-speed environment (e.g., on a high-speed train (HST)) and one or more network entities. The wireless node may transmit one or more reference signals associated with a Doppler estimation procedure to the one or more network entities. The network entities may use the one or more reference signals to generate a set of Doppler compensation parameters to use while communicating with the wireless node and the one or more wireless devices. In some examples, the wireless node may receive control information or data from the one or more wireless devices, aggregate the information, and transmit the aggregated information to the one or more network entities on behalf of the wireless devices.

Abstract: Apparatus, methods, and computer program products for beam updating are provided. An example method includes receiving DCI. The method further includes determining, based on the DCI, whether the DCI is associated with a beam update for uplink, downlink, or a combination of the uplink and the downlink. The method further includes determining, from the DCI, a TCI state that indicates a beam for the uplink, the downlink, or the combination of the uplink and the downlink.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a list of transmission configuration indicator (TCI) state patterns where each entry in the list may correspond to a different TCI state pattern. The base station may transmit an indication of a selected entry from the TCI state pattern list and transmit a grant to the UE indicating that resources have been allocated in for transmitting a transport block (TB). The UE may receive the grant and attempt to receive the TB in accordance with the indicated TCI state pattern. The UE may generate multi-bit feedback to indicate whether the UE was able to successfully decode the TB and transmit the feedback to the base station. The base station may use the multi-bit feedback for determining whether to select a different TCI state pattern.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communication. In one aspect, a base station (BS) transmits a message to a UE indicating a designation of a signal as a PLRS. The designation of the signal as the PLRS is associated with an application time interval, and after expiration of the application time interval, the BS receives an uplink signal from the UE having a transmit power level associated with the signal.
