Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive an indication of a set of corresponding physical downlink control channel (PDCCH) candidates that includes at least a first PDCCH candidate included in a first control resource set (CORESET) and a corresponding second PDCCH candidate included in a second CORESET, wherein the first CORESET and the second CORESET have different transmission configuration indication (TCI) states; and selectively perform, based at least in part on a configuration, at least one of: independent decoding of the first PDCCH candidate, independent decoding of the second PDCCH candidate, or joint decoding of the first PDCCH candidate and the second PDCCH candidate. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may be configured with multiple control resource sets (CORESETs) within a slot. The UE may identify a set of physical downlink control channel (PDCCH) occasions to monitor within the slot, where each PDCCH occasion corresponds to a search space set for a CORESET. The UE may determine a first configuration and a second configuration for monitoring the PDCCH occasions, where the first configuration corresponds to slot-based thresholds and the second configuration corresponds to symbol-based or occasion-based thresholds for monitoring. These thresholds may specify a threshold number of PDCCH candidates to blind decode, a threshold number of non-overlapping control channel elements (CCEs) to perform channel estimation for, or both, where the threshold numbers support low latency processing at the UE. Either the configuration or the UE may enforce the thresholds.

Abstract: Certain aspects of the present disclosure provide techniques for remote interference determination at a first base station based on assistance from one or more neighboring base stations of the first base station. Certain aspects provide a method for wireless communication by a first base station (BS). The method includes receiving from a second BS neighboring the first BS an uplink interference report request. The method further includes transmitting to the second BS an uplink interference report in response to the uplink interference report request, the uplink interference report comprising information indicative of uplink interference caused by one or more user equipments communicating on an uplink with the first BS.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify one or more radio frequency (RF) spectrum bands for full-duplex communications, and may signal an indication of the UE's capability to support full-duplex communications for each RF spectrum band. The UE may further receive one or more configurations for full-duplex communications, which, in some examples, may be based on the UE's indicated capabilities. As an example, the UE may identify a guard band configuration for full-duplex communications, where the guard band configuration may be based on one or more aspects of resources used for the full-duplex communications. In other cases, the UE may identify a transmission hopping or antenna switching configuration for full-duplex communications. In any case, the UE may communicate with a base station in accordance with the one or more configurations and the UE's capabilities.

Abstract: Wireless communications systems and methods related to determining a QCL for receiving a reference signal are provided. A user equipment (UE) determines a QCL configuration for receiving a reference signal during a first time period based on a transmit beam direction to be used for transmission during the first time period. The user equipment receives the reference signal using a first receive beam direction based on the QCL configuration while transmitting a first communication signal using the transmit beam direction in a common frequency band during the first time period.

Abstract: Certain aspects of the present disclosure provide techniques for reference signal monitoring and transmission for remote interference management. In some cases, an aggressor base station decides to monitor for reference signals (RSs) transmitted from at least one victim BS, for example, regardless of an amount of interference from at least one remote BS detected by the first base station and participating in a remote interference mitigation (RIM) process based on the monitored RS. In some cases, a first BS transmits reference signals (RSs) as part of a remote interference mitigation (RIM) process, in response to a determination that it is an aggressor BS whose downlink transmissions possibly interfere with reception of uplink transmissions by at least one remote BS, a victim BS whose reception of uplink transmissions are possibly interfered with by downlink transmissions from the at least one remote BS, or both an aggressor BS and a victim BS.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station by initiating a random access procedure with a multi-root preamble. The UE may receive, from the base station, a configuration message that indicates one or more parameters for the multi-root preamble. The one or more parameters may include cyclic shifts, phase rotations, and sequence roots corresponding to a plurality of sequences. The base station may identify the one or more parameters and transmit the configuration message based on the identifying. The UE may identify the one or more parameters for the multi-root preamble based on the configuration message and/or a pre-configuration at the UE. The UE may transmit, to the base station, the multi-root preamble based at least in part on the one or more parameters.

Abstract: Methods, systems, and devices for wireless communications are described and may include a user terminal and a satellite establishing a communication link over a channel having a channel delay and a medium access control-control element (MAC-CE) delay being determined based on the channel delay. The user terminal and the satellite may be within a non-terrestrial network (NTN). The user terminal may receive a MAC-CE command that indicates a communication parameter to be implemented or adjusted. The user terminal may transmit feedback, for example, to the satellite in response to the MAC-CE command, and the user terminal and the satellite may communicate according to the communication parameter in the MAC-CE command after an end of the MAC-CE delay.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit uplink transmissions according to a frequency hopping pattern. The UE may identify that a first set of uplink transmissions are to be transmitted to a base station by a first set of resources (e.g., a first set of slots, a first set of frequency resources) as indicated by the frequency hopping pattern. The UE may further identify, based on the frequency hopping pattern, that a second set of uplink transmissions are to be transmitted to the base station by a second set of resources (e.g., a second set of slots, a second set of frequency resources). The first set of slots and the second set of slots may each include more than one slot. Additionally, the first and second set of resources may be within a same bandwidth part or in different bandwidth parts.
