Abstract: A first wireless device transmits one or more transmissions for a second wireless device to a repeater for repetition to the second wireless device; adjusts a repeater operation based on a phase noise in transmission between the first wireless device and the repeater; and communicates with at least one of the repeater or the second wireless device based on the adjusted repeater operation. A repeater receives from a first wireless device, a request for the repeater to report a phase noise in transmissions between the first wireless device and the repeater for repetition with a second wireless device; and transmits a report of the phase noise to the first wireless device based on the request. A repeater receives, from a first wireless device, a transmission for repetition with a second wireless device; and transmits the repetition of the transmission to the second wireless device with a phase noise compensation.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for training a beam for multiple component carriers (CCs) for concurrent communications in a wireless communications system associated with limited user equipment (UE) capabilities. The UE receives, via a first receive beam, a first reference signal on a group of CCs over a first symbol. The UE also receives, via a second receive beam, a second reference signal on the group of CCs over a second symbol. The UE selects a receive beam for a subsequent communication based on determining a value of a parameter for each of the first and the second receive beam.

Abstract: A method of wireless communication receives multiple beams from a base station. The method also simultaneously reports a signal to interference plus noise ratio (SINR) for multiple beams with a single channel measurement resource (CMR) and a single interference measurement resource (IMR). The single IMR is configured for multiple interference sources. A method of wireless communication by a base station configures a UE with a group of interference sources. The base station also configures the UE with an interference measurement resource associated with the group of interference sources.

Abstract: Aspects relate to techniques for signaling the capability of a wireless communication device (e.g., a UE) to support demodulation reference signal (DMRS) bundling for channel estimation across two or more slots in the sidelink or uplink. In some examples, a transmitting UE may transmit a DMRS bundling indication to a receiving device (e.g., a receiving UE for sidelink DMRS bundling or a base station for uplink DMRS bundling). The DMRS bundling indication may indicate a capability of the transmitting UE to support DMRS bundling. The transmitting UE may then transmit a respective set of DMRSs within each of two or more slots during a DMRS bundling window to the receiving device based on the transmitting wireless communication device and the receiving device supporting DMRS bundling.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a first user equipment (UE) identifies a trigger condition associated with a first communication link with a base station and establishes a second communication link with a second UE. The UE may transmit a relay request to the second UE based on the trigger condition, wherein the relay request instructs the second UE to relay communications for the first UE. The first UE communicates with the base station via the second communication link. In another example, a base station establishes communication links with a first and second UE. The base station receives a data forwarding request that instructs the base station to use the second UE to relay communications between it and the first UE. The base station communicates with the first UE via the second communication link based at least in part on the relay request.

Abstract: Apparatus, methods, and computer-readable media for multiplexing of overlapped uplink channel transmission repetitions are disclosed herein. A user equipment (UE) may determine whether a first subset of a first set of uplink channel transmission repetitions overlaps with a downlink transmission and determine whether to transmit a second subset of the first set of uplink channel transmission repetitions when the first subset overlaps with the downlink transmission. In some aspects, the second subset includes one or more uplink channel transmission repetitions that do not overlap with the downlink transmission. The UE may transmit, to a base station over an uplink channel, a second set of uplink channel transmission repetitions having the first subset and the second subset of the first set of uplink channel transmission repetitions when the second subset is determined to be transmitted. Thus, the reliability of uplink repetitions can be increased.
