Abstract: Beam failure recovery (BFR) in a multiple Downlink Control Information (mDCI) mode may include receiving, by a user equipment (UE), a Downlink Reference Signal (DL RS) set from a next generation Node B (gNB). The DL RS set may be associated with a link between the UE and the gNB and indicate beam failure detection (BFD) is to be performed for the link. The BFR may further include performing, by the UE, a beam failure detection (BFD) for the link using the DL RS set, and performing, by the UE, a candidate beam detection (CBD) for the link, the CBD determining a candidate beam for the link by determining a beam having a reference signal receiving power (RSRP) that is larger than an RSRP threshold. The BFR may further include transmitting, by the UE, a beam failure recovery request (BFRQ) indicating the link to the gNB.

Abstract: Apparatuses, systems, and methods for channel access scheme enhancements for systems operating in unlicensed higher frequency bands. A wireless device may perform channel access detection (CAD) measurements on a channel at a first periodicity, determine a CAD metric based on the CAD measurements at a second periodicity, and select, for the channel, a first channel access scheme from a plurality of channel access schemes based on comparison of the CAD metric to a threshold. The first channel access scheme may include a first set of channel access procedures that may define physical channels and signals to utilize respective channel procedures. In instances when the CAD metric is below the threshold, the first channel access scheme may include accessing a channel using a first listen before talk (LBT) procedure that is less restrictive than a second LTB procedure used when the CAD metric is above the threshold.

A user equipment device (UE) may receive, via a first reception path, an RRM related signal and receive, via a second reception path, a non-RRM related signal that may be multiplexed with the RRM related signal onto a symbol. The first reception path may be a first antenna port of an antenna panel or a first antenna panel of the UE and the second reception path may be a second antenna port of the antenna panel or a second antenna panel of the UE. The RRM related signal may include a reference signal for RRM. and may be included in a non-zero power (NZP) interference measurement.

Abstract: Systems, devices, and techniques for preemption indication in wireless communication systems are described. A described technique includes receiving, by a User Equipment (UE) via a physical downlink control channel (PDCCH), a downlink control information (DCI) message in a Control Resource Set (CORESET) configured with a transmission configuration indicator (TCI) state, the TCI state being associated with a transmission reception point (TRP), the DCI message comprising a downlink preemption indication for the TCI state; and applying preemption to a reference signal or a channel associated with the TCI state responsive to the downlink preemption indication.

Abstract: A user equipment (UE) communicates with transmission-reception points (TRPs). When the UE generates uplink control information (UCI), it determines a higher layer index (HLI) value to target the UCI to the appropriate TRP. (Possible values of the HLI are associated with the TRPs.) For UCI on Physical Uplink Control Channel (PUCCH), the HLI value may be determined: based on an HLI value configured for a control resource set (CORESET), or for particular Physical Uplink Control Channel (PUCCH) resources; based on UCI type or spatial relation data or an index related to PUCCH resources. For UCI on a configured-grant Physical Uplink Shared Channel (PUSCH), the HLI value may be based on higher layer signals or an indicator relating to channel sounding on spatial relation data. For UCI on MsgA PUSCH in a two-step random access procedure, the HLI value may be based on PUSCH resource unit or PUSCH opportunity.

Abstract: The present disclosure is directed to AP-SRS triggering offset enhancement for further enhanced MIMO. User equipment (UE), base stations, apparatus, methods, computer-readable memory media, and computer program products are disclosed. The UE may be configured to receive an offset information associated with AP-SRS transmission of the UE; determine a slot offset associated with the AP-SRS transmission, at least based on the offset information; determine a specific slot for the AP-SRS transmission, based on the determined slot offset; and perform the AP-SRS transmission in the determined specific slot.

Abstract: A user equipment (UE) associated with a non-terrestrial network (NTN) is disclosed. The UE comprises a processor configured to determine a first time offset, based on processing a timing offset indication signal comprising the first time offset or an associated parameter, received from a base station. In some embodiments, the first time offset is indicative of a time delay in downlink (DL) to uplink (UL) interaction between the UE and the base station. The processor is further configured to determine a second time offset, based on processing a subsequent timing offset indication signal comprising the second time offset or an associated parameter, received from the base station at a subsequent time instance. In some embodiments, the processor is further configured to update the first time offset with the second time offset.

Abstract: Supporting transmission of multiple hybrid automatic repeat request acknowledgments (HARQ-ACKS) within a single slot may include encoding a first HARQ-ACK and a second HARQ-ACK within the single slot for transmission to a base station. The first HARQ-ACK may be transmitted via a first physical uplink control channel (PUCCH) and the second HARQ-ACK may be transmitted via a second PUCCH. Based on encoding the first HARQ-ACK and the second HARQ-ACK within the single slot, one or more additional uplink (UL) signals colliding with at least one of the first HARQ-ACK and the second HARQ-ACK within the single slot may be responded to based on a configuration of the UE.
