Abstract: Techniques discussed herein can facilitate listen before talk procedures for clear channel assessment signaling. One example aspect is a baseband processor of a user equipment (UE), including one or more processors configured to receive system information including a region indication for clear channel assessment (CCA) procedures. The CCA procedures are associated with a listen before talk (LBT) region configuration for one of a first region, a second region, or a third region. One or more processors are configured to receive a downlink control information (DCI) in a physical downlink control channel (PDCCH) message that includes a DCI CCA indication. Subsequently, the one or more processors are configured to perform an initial LBT procedure associated with the region indication and generate a random access channel (RACH) message after performing the initial LBT procedure. Finally, the one or more processors generate an uplink (UL) message according to the DCI CCA indication.

Abstract: A receiving user equipment (UE) may be configured perform operations relating to sidelink communications with a transmitting UE. The receiving UE may establish a sidelink session with a transmitting UE, perform a local sensing, receive a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), and reserved multiple resources from the transmitting UE, whereby the transmitting UE reserves the reserved multiple resources. The receiving UE determines whether a coordination message is triggered and, in response to the coordination message being triggered, the receiving UE transmits the coordination message to the transmitting UE, the coordination message indicating whether a collision occurs among the reserved multiple resources.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to perform PUCCH repetition based on signaling from at least one base station. The UE may connect to at least one base station. The UE may receive signaling from the at least one base station configuring physical uplink control channel (PUCCH) transmission. The signaling may indicate a plurality of PUCCH resources for PUCCH repetition. The signaling may indicate a plurality of beams for PUCCH repetition. Based on the signaling from the at least one base station, the UE may transmit the PUCCH a plurality of times using the plurality of PUCCH resources and the plurality of beams.

Abstract: A base station maps physical downlink control channel (PDCCH) candidates and PDCCH transmissions for multi-transmission reception point (TRP) operation. The base station determines that a control resource set (CORESET) is to be shared by at least a first TRP and a second TRP corresponding to a cell of a network, performs resource element group (REG) bundle to virtual REG bundle mapping on a per TRP basis, wherein multiple REG bundles are indexed on the per TRP basis, performs virtual REG bundle interleaving across the first TRP and the second TRP, performs control channel element (CCE) to interleaved REG bundle mapping and transmits downlink control information (DCI) using the CORESET, wherein the CORESET is configured based on, at least, the CCE to interleaved REG bundle mapping.

Abstract: Disclosed are techniques for reducing likelihood of Random Access Channel (RACH) transmission blockages and thereby facilitate an initial access procedure for new radio (NR) unlicensed spectrum (NR-U) operation in a fifth generation (5G) wireless communication system including an NR node. In some embodiments, a parameter generated by a gNB and received by a UE indicates that, from among a set of consecutive RACH Occasions (ROs), a gap is available for performing a listen-before-talk (LBT) procedure before commencing a RACH transmission.

Abstract: Methods and devices for a UE to multiplex uplink control information (UCI). The UE establishes a connection with a base station. The UE determines whether to multiplex first UCI by first identifying whether intra-priority timing overlap exists between the timing resources of the first UCI and a PUSCH with the same priority. Subsequently, the UE identifies whether inter-priority timing overlap exists between the timing resources of the first UCI and a second PUCCH with a different priority from the first PUCCH. Finally, the UE identifies whether the timing resources of the first UCI overlap with a second PUSCH with a different priority than the first PUCCH. The UE multiplexes the first UCI based on the determination whether to multiplex the first UCI, and transmits the multiplexed first UCI to the base station.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) during a random access channel (PRACH) procedure. The UE receives a physical random access channel (PRACH) resource on a first sub-band of a component carrier (CC), wherein the CC is divided into a plurality of sub-bands and receives a Type1-PDCCH CSS (Physical Downlink Control Channel Common Search Space) set on a second sub-band of the CC, wherein the Type1-PDCCH CSS set corresponds to the PRACH resource.
