Abstract: A base station may determine a root for a sequence to be included in a signal to a UE. The base station may generate a generalized Chu sequence based on the root and scramble the generalized Chu sequence using a pseudorandom sequence that is common to a plurality of base stations. The base station may transmit the scrambled generalized Chu sequence to indicate the beginning of a downlink transmission. The UE may receive this scrambled generalized Chu sequence and determine if a beginning of a downlink transmission from a serving base station based on the received generalized Chu sequence and an expected generalized Chu sequence.

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: A method, an apparatus, a base station, and a user equipment (UE) for wireless communication are provided to reduce the retransmission latency for URLLC communications. Upon receiving a downlink data transmission, a UE waits until it completes decoding of the received downlink data transmission before it can send an ACK/NAK report on the decoded downlink data transmission. In case of a decoding failure, the base station cannot start retransmission until the UE finishes the decoding of the downlink data transmission and sends the ACK/NAK report and until the base station finishes decoding of an NAK in the ACK/NAK report. This considerable retransmission latency may not meet stringent latency requirements of some URLLC applications. A two-stage ACK/NAK reporting is disclosed to reduce the retransmission latency where the UE sends an early ACK/NAK report upon partially completing the decoding of the downlink data transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first set of repetitions of a physical uplink shared channel (PUSCH) communication using a plurality of sets of values for a set of transmission parameters on a first set of frequencies using frequency hopping; and transmit a second set of repetitions of the PUSCH communication using the plurality of sets of values for the set of transmission parameters on a second set of frequencies using frequency hopping. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a first interference measurement on a first subband of a plurality of subbands configured for the UE and a second interference measurement on a second subband of the plurality of subbands. The UE may identify a first interference level based at least in part on the first interference measurement and a second interference level based at least in part on the second interference measurement. The UE may transmit, to a base station, a first sounding reference signal (SRS) on the first subband and a second SRS on the second subband, wherein an SRS sequence of the first SRS indicates the first interference level, and wherein an SRS sequence of the second SRS indicates the second interference level. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink assisted retransmissions, in which a first UE obtains first data intended for a second UE by decoding a first transmission of the first data targeting the second UE, receives signaling indicating the first UE is to retransmit the first data to the second UE, and retransmits the first data to the second UE, via a sidelink, in response to the signaling.
