Abstract: Techniques described herein involve the use of quasi-co-location (QCL) capabilities and spatial relation assumption to enable a UE to designate a single beam for connections with a base station during a physical random access channel (PRACH) procedure. Once the PRACH procedure is complete, the beam may be reset after a pre-determined duration, which may account for decoding latency, or maintained until additional transmission configuration indication (TCI) is received. Also addressed are scenarios involving multiple transmission reception points (TRPs) and switching between beam management schemes based on one or more factors including device capabilities.

Abstract: A network-controlled repeater (NCR) may receive configuration information from a base station to configure one or more receive (Rx) beams and corresponding time-domain resources for potential reception from one or more user equipments (UEs). The NCR may monitor for reception of a physical uplink channel or signal from the one or more UEs on the configured one or more Rx beams on the corresponding time-domain resources and determine that the physical uplink channel or signal is not received for at least a threshold amount of time. Additionally, the NCR may determine to refrain from at least one of additional monitoring for reception of the physical uplink channel or signal from the one or more UEs or transmission of one or more synchronization signal block (SSBs) to the one or more UEs for a duration of time.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs. The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.

Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.

Abstract: This disclosure relates to techniques for performing beam failure recovery and receiving control information with improved reliability in a wireless communication system. The techniques may include the use of multiple beams in conjunction with performing beam failure recovery, for example including identifying multiple candidate beams for beam failure recovery. The techniques may also or alternatively include the use of multiple beams to provide repetitions of control information for search space and control resource set index 0.

Abstract: The present application relates to selecting one or more of activated transmission configuration indicator (TCI) states for communications between a network and a user equipment. In an example, the network includes multiple transmission and reception points (TRPs) with which the UE communications. An activated TCI state can be a unified downlink TCI state that applies to multiple downlink channels or a unified uplink TCI state that applies to multiple uplink channels, where this state has already been activated by the network for the UE. Based on a predefined set of rules or network-based signaling, the UE can determine for a downlink or uplink communication with the network, one or more of the activated TCI states to use to then perform the downlink or uplink communication with the network.

Abstract: Systems, methods, and circuitries are provided for supporting aggregated retransmissions. In one example, a method includes receiving control information that indicates resources including one or more slots for communication of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) transmission that includes at least one PDSCH/PUSCH retransmission A slot group to which a selected one of the one or more slots belongs is identified. The method includes configuring operation to receive the PDSCH transmission or to transmit the PUSCH transmission based on the resources. In response to determining that a PDSCH/PUSCH retransmission of the PDSCH/PUSCH transmission is scheduled for a slot outside the identified slot group, operation is configured to provide hybrid automatic repetition request (HARQ) feedback based on PDSCH/PUSCH retransmissions scheduled for slots within the identified slot group, wherein the HARQ feedback is not based on PDSCH/PUSCH scheduled for slots outside the identified slot group.

Abstract: Systems and methods for control signaling for beam searching latency reduction are disclosed herein. A g Node B (gNB) may determine that a first Synchronization Signal Block (SSB) and a second SSB are to be spatially correlated and may select a first transmit (Tx) beam to transmit the first SSB and a second Tx beam to transmit the second SSB accordingly. The gNB may also transmit a correlation message including spatial correlation information to help a UE determine the spatial correlation. The UE may measure the first SSB on a first subset of a plurality of receive (Rx) beams and measure the second SSB on a second subset of the plurality of Rx beams, and select an Rx beam for one or both. In some embodiments, channel state information reference signals (CSI-RS) that are quasi co-located (QCLed) with a given SSB may be measured in place of the SSB.
