Abstract: In order to improve the selection of search space candidates for a downlink control channel, an apparatus determines a set of decoding candidates of a lower aggregation level for a downlink control channel based on a random selection from a plurality of potential decoding candidates, wherein the plurality of potential decoding candidates are defined from a second set of decoding candidates of a higher aggregation level. The apparatus then attempts to decode the downlink control channel based on determined sets of decoding candidates of different aggregation levels. The downlink control channel may comprise a PDCCH.

Abstract: Certain aspects of the present disclosure provide techniques for performing radio link monitoring (RLM) and radio link failure procedures in multiple-TRP (mTRP) communications, wherein the first TRP is part of a first cell group comprising the first TRP and one or more additional TRPs. The techniques include a method of wireless communication by a user equipment (UE), comprising establishing a plurality of radio links between the UE and a first transmission reception point (TRP) and a second TRP, determining an RLM resource of a first radio link of the plurality of radio links, monitoring the first radio link according to the determined RLM resource, detecting an RLF of the first radio link, determining that the first TRP is associated with the RLF of the first radio link based on the RLM resource of the first radio link, and transmitting an RLF notification indicating the RLF of the first radio link.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a particular control resource set (CORESET), downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH). The UE may be configured with multi-DCI based multi-transmission/reception point (TRP) operation. The UE may determine, based at least in part on the UE being configured with multi-DCI based multi-TRP operation, a fixed higher layer index that identifies a CORESET group with which the particular CORESET is associated. The UE may perform an operation, associated with receiving the PDSCH or transmitting the PUSCH, based at least in part on the fixed higher layer index identifying the CORESET group with which the particular CORESET is associated. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method determines resources to monitor for beam failure detection (BFD) when the UE is in a mode of operation involving at least first and second transmitter receiver points (TRPs). The method then detects a beam failure based on monitoring of the determined resources. The method further triggers a beam failure recovery (BFR) procedure based on the detection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, from a user equipment (UE), a message that indicates whether the UE received a downlink transmission from the base station in a first frequency range. The base station may schedule one or more reference signal (RS) transmissions in the first frequency range and one or more RS transmissions in a second frequency range based at least in part on the message received from the UE, and reschedule the downlink transmission on a component carrier in either the first frequency range or the second frequency range based at least in part on channel quality information that is determined from the one or more RS transmissions in the first frequency range and the one or more RS transmissions in the second frequency range. Numerous other aspects are provided.
