Abstract: Apparatus, methods, and computer-readable media for sounding reference signals (SRSs) triggered by random access channel (RACH) message 2 for RACH message 4 physical downlink shared channel quasi co-location (QCL) are disclosed herein. A user equipment (UE) may transmit, to a base station via a transmit beam over a random access channel, a random access preamble and receive a random access response based on the random access preamble. The UE may transmit, to the base station via a plurality of transmit sub-beams, a plurality of SRS transmissions triggered by the random access response. The UE can receive, from the base station, a downlink control signal that includes an SRS resource indicator (SRI) that indicates a selected transmit sub-beam for a corresponding SRS transmission. The UE can use the SRI as QCL information for improved reception of downlink signaling with a refined receive sub-beam corresponding to the selected transmit sub-beam.

Abstract: Apparatus, methods, and computer-readable media are disclosed herein for facilitating spatial misalignment tracking for OAM beams in millimeter wave and higher frequency bands. An example method for wireless communication at a first communication device includes receiving, from a second communication device, a first misalignment tracking RS and a second misalignment tracking RS for an OAM transmission. The example method also includes determining a misalignment based on the first misalignment tracking RS, the second misalignment tracking RS, and using a subset of antenna elements of an antenna array of the first communication device. Additionally, the example method includes adjusting reception of a subsequent OAM transmission from the second communication device at the antenna array of the first communication device.

Abstract: A synchronization signal block (SSB) transmitted by a neighbor base station may interfere with a physical downlink shared channel (PDSCH) transmitted by a serving base station. A user equipment (UE) that receives both the SSB and PDSCH may mitigate the interference to improve an error rate of decoding the PDSCH. The UE may receive a first SSB including a first broadcast channel (BCH) from a second base station other than a serving base station. The UE may decode the first SSB. The UE may determine, based on the first SSB and the first BCH, that the PDSCH scheduled by the serving base station will overlap with a second SSB from the second base station. The UE may estimate a channel of the second SSB based on the decoded first SSB. The UE may remove a reconstructed second SSB from the PDSCH. The UE may decode the PDSCH.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive a system information message from a base station indicating a beam sweeping procedure supported by the base station. Based on the system information message, the UE may receive, as part of the indicated beam sweeping procedure, a first synchronization signal block (SSB) as part of first set of SSBs, and a second SSB as part of a second set of SSBs. The UE may then transmit, to the base station, one or more messages that indicate a narrow beam for communications between the UE and the base station. In some cases, the indicated beam may correspond to the first SSB and the second SSB, and is indicated on one or more random access channel (RACH) occasions associated with the beam sweeping procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A first device, such as a user equipment (UE) or base station, may receive, at a first antenna of a first antenna array, a first set of reference signals. The first device may measure the phase for each of the reference signals and estimate a linear offset between the first antenna array and a second antenna array of a second device that transmitted the reference signals. The first device may adjust an alignment of the first antenna array according to the estimated linear offset. The first device may receive a second set of reference signals, measure the phase for each of the reference signals, and estimate one or more rotational offsets between the first antenna array and the second antenna array. The first device may adjust the alignment of the first antenna array based on the one or more rotational offsets.

Abstract: Methods, systems, and devices for wireless communications are described. A communications device may transmit a first signal. The first signal may be transmitted from a first antenna array of the communications device through a lens of the communications device in a direction. An energy of a portion of the first signal may be below a threshold based on a position of a second antenna array of the communications device. The portion of the first signal may correspond to a portion of a reflection of the first signal that overlaps with the position of the second antenna array. The communications device may concurrently receive, at the second antenna array, a second signal originating from another direction, where the second signal may be focused in the direction of the second antenna array based on the lens.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications networks may support carrier aggregation such that a user equipment (UE) may operate on both a primary cell using a first frequency range and a secondary cell using a second frequency range. In some cases, a beam failure associated with one or more beams of the secondary cell may be identified by the UE, and a beam failure recovery procedure may be triggered. The UE may send a beam failure recovery request message in an uplink data field of a physical uplink control channel (PUCCH) message to a base station of the primary cell. In response to the beam failure recovery request message, the base station of the primary cell may transmit a response to the UE which includes beam failure mitigation information.

Abstract: Methods, systems, and devices for wireless communications are described. A channel engineering device may receive control signaling that triggers the channel engineering device to perform one or more angle of arrival (AoA) measurements on one or more reference signals and transmit an AoA measurement report based on the AoA measurements. The base station may process the AoA measurement report and send a control message that configures one or more settings at the channel engineering device. The base station may determine a beam shaping configuration that modifies the one or more settings at the channel engineering device to reflect, focus, refract, or filter signal energy of a transmission by the base station toward a user equipment (UE), a transmission by the UE toward the base station, or both. The base station and one or more UEs may communicate using the channel engineering device based on the beam shaping configuration.

Abstract: Wireless communications systems and methods related to beam refinement with simultaneous spatial-division multiplexed beams are provided. A user equipment (UE) receives, from a base station (BS), a plurality of reference signals in a set of beam directions. The receiving includes receiving, simultaneously during a first symbol, at least a first reference signal of the plurality of reference signals in a first beam direction of the set of beam directions and a second reference signal of the plurality of reference signals in a second beam direction of the set of beam directions, where the second beam direction is different from the first beam direction. The UE transmits, to the BS, a beam report indicating received signal measurements for two or more beam directions of the set of beam directions.
