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.

Abstract: Systems, methods, and processors are provided to support beamformed sidelink communication. In one example, a user equipment (UE) is configured for sidelink communication in a first unicast pair that includes the UE and a second UE. The UE includes a memory and one or more processors coupled to the memory. The one or more processors are configured to, when executing instructions stored in the memory, cause the UE to receive a message providing notification of sidelink communication between the UE and the second UE, and in response, perform sidelink communication of first sidelink data using a first transmit (TX) beam associated with the first unicast pair or a first receive (RX) beam associated with the first unicast pair.

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: 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.
