Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink transmission and interlace uplink transmission. For example, some aspects of this disclosure relate to a base station including a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor divides a plurality of candidate Synchronization Signal Block (SSB) positions in a time window into a plurality of groups and communicates, using the transceiver, information associated with the plurality of groups of candidate SSB positions to the UE. The processor further performs a listen-before-talk (LBT) procedure. In response to the LBT procedure being successful, the processor determines a first group of the plurality of groups and transmits, using the transceiver, one or more SSBs on one or more candidate SSB positions of the first group to the UE.

Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may receive, from a base station, an indication of parameter settings of a port selection codebook. The port selection codebook includes a port selection matrix W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. Based at least in part on the parameter settings, the UE selects L CSI-RS ports, Mv frequency basis from a window of N consecutive frequency basis; and up to beta*L*Mv entries per layer, where beta is a percentage of the L*Mv entries per layer. The UE reports one or more of the port selection matrix W1, the up to beta*L*Mv entries in the combinational coefficient matrix W2 per layer, and the frequency basis selection matrix Wf to the base station.

Abstract: Aspects of the present disclosure are related to a method performed by a user equipment (UE). The method includes selecting a candidate resource set with a plurality of candidate resources from a resource selection window. The plurality of candidate resources includes a reserved resource that is reserved by at least one other UE. The method includes determining that the reserved resource is associated with a priority level PRX that is higher than a transmission priority level PTX associated with the UE. The method further includes excluding the reserved resource from the candidate resource set based at least in part on the determining.

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.
