Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information including multiple transmission configuration indication (TCI) states associated with a control resource set (CORESET). The UE may receive, from the base station, a physical downlink control channel (PDCCH) in a region associated with the CORESET, wherein the PDCCH includes at least one control channel element (CCE). The UE may perform blind decoding for multiple configured PDCCH candidates based at least in part on a resource element group (REG) bundle included in the at least one CCE, wherein the multiple configured PDCCH candidates are associated with one or more of the multiple TC states associated with the CORESET. Accordingly, the UE may identify the PDCCH transmitted by the base station based at least in part on the blind decoding.

Abstract: Certain aspects of the present disclosure provide techniques for enhancements to channel state information (CSI) reporting. A method that may be performed by a user equipment (UE) includes obtaining, from a network entity, a CSI reporting configuration for reporting CSI for a channel. The method further includes generating a model of an interference pattern for the channel, and predicting one or more candidate interference levels for one or more upcoming slots using the model. The method further includes reporting information regarding the candidate interference levels to the network entity.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for selecting a beam to be allocated for transmitting downlink (DL) data to user equipment (UE). In some implementations, a UE receives a reference signal on each of a number of beams associated with a base station, and determines a delay spread value for each beam. The UE identifies each beam for which the determined channel delay spread value is less than a threshold value, and determines a reference signal received power (RSRP) level for each identified beam. The UE transmits an indication of the determined RSRP levels of the identified beams to the base station, and receives, in response to the transmitted indication, a selection of the beam to be allocated for DL transmissions to the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a random access channel (RACH) signature from among one or more RACH signatures associated with a synchronization signal block (SSB). The UE may transmit, to a base station (BS), a RACH communication using the selected RACH signature. Numerous other aspects are provided.

Abstract: Aspects described herein relate to receiving multiple synchronization signal block (SSB) signals from a base station, wherein the multiple SSB signals are each beamformed based on a different directional beam, selecting a signature from a signature space of a first SSB of the multiple SSB signals, and transmitting, based on the signature, a random access message to the base station, wherein the random access message includes an indicator of a preferred SSB of the multiple SSB signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit receive point in a multi-TRP configuration, a downlink control information (DCI) communication. The UE may identify one or more quasi-co-location (QCL) relationships associated with a control resource set (CORESET) or a search space set in which the DCI communication is received. A QCL relationship, of the one or more QCL relationships, is associated with one or more physical downlink shared channel (PDSCH) layers that are transmitted from a second TRP in the multi-TRP configuration. Numerous other aspects are provided.

Abstract: Aspects directed towards a frame-based equipment (FBE) design for a multi-operator New Radio shared spectrum (NR-SS) are disclosed. In one example, at least one contention slot is monitored within a fixed frame period of an unlicensed spectrum, and a determination is performed of whether a channel reservation signal associated with a higher priority node has been detected within the at least one contention slot. For this example, the at least one contention slot is associated with a resource of a subsequent fixed frame period of the unlicensed spectrum. A determination is then made of whether to transmit communication via the resource. Here, the communication is transmitted via the resource, if the channel reservation signal is not detected, and the communication is not transmitted via the resource, if the channel reservation signal is detected.
