Abstract: A user equipment (UE), or other network component can operate to configure different sets of resources for an uplink (UL) physical channel for an uplink (UL)-to-downlink (DL) channel occupancy time (COT) sharing to coexist with another radio access technology (RAT). An energy detection (ED) threshold can be selected from the different sets of resource configurations for an UL transmission based on one or more conditions. A gap can be configured between a physical random access control channel (PRACH) transmission and a PUSCH transmission based on one of at least a first value associated with a numerology between the PRACH and the PUSCH and a second value greater than the first value. The UL transmission can be provided based on the ED threshold or the configured conditional gap via the UL physical channel.

Abstract: A method determines a number of physical sidelink shared channel (PSSCH) symbols and a number of PSSCH demodulation reference signal (DMRS) symbols that will occur in a timeslot that is used for scheduling. PSSCH DMRS locations in the timeslot are derived based on applying the PSSCH DMRS symbols and the PSSCH DMRS symbols to a look-up table. A number of PSSCH DMRS resource elements (REs) is calculated based on the PSSCH DMRS locations and a scheduled number of PSSCH sub-channels. This number of PSSCH DMRS REs is used to determine a transport block size (TBS) included in transmissions over a sidelink channel.

Abstract: Systems, methods, and circuitries are provided for configuring HARQ feedback for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) communication. In one example, a method includes identifying a physical uplink control channel (PUCCH) resource in a first slot for communicating a hybrid automatic repeat request (HARQ) codebook. The method includes determining a set of SPS PDSCH receptions for which feedback is multiplexed in the HARQ codebook based on SPS PDSCH configurations for each component carrier and each slot, a UE capability for number of SPS PDSCH receptions per slot, and a prioritization protocol. The method includes selecting a codebook type based on whether a PDSCH is scheduled by way of a dynamic grant for any of the plurality of slots, constructing the HARQ codebook based on the set of SPS PDSCH receptions and the selected codebook type, and transmitting the HARQ codebook to a next generation node

Abstract: A user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.

Abstract: A method and apparatus of a device that handles time-varying packet size in the downlink. In some embodiments, the method performed by a user equipment (UE) comprises: receiving a first signaling comprising configuration of downlink (DL) Semi-Persistent Scheduling (SPS), wherein the DL SPS configuration comprises a periodicity of the DL SPS and a first indication for a first physical layer resource, and wherein the first physical layer resource is used to dynamically modify size of a second physical layer resource for SPS DL data transmission; receiving a second signaling that activates reception based on the DL SPS, wherein the second signaling comprises information to specify a boundary of the second physical layer resource; monitoring the first physical layer resource on each SPS occasion based on the periodicity to decode a second indication; determining the size of the second physical layer resource for SPS DL data transmission, based on the second indication; and receiving data on the second physical layer resource determined for each SPS occasion based on the determined size.

Abstract: Apparatuses, systems, and methods for triggering and signaling of an inter-UE coordination message. A coordinating UE may determine to transmit, to a source UE, a set of resources for the source UE to use for sidelink communications. The determination may be based, at least in part, on an occurrence of at least one condition. The at least one condition may include the coordinating UE receiving a sidelink coordination request message form the source UE, the coordinating UE detecting a resource reservation collision between the source UE and a destination UE, and/or the coordinating UE detecting a half-duplex restriction at the source UE or the destination UE. The coordinating UE may transmit an inter-UE coordination message to the source UE. The inter-UE coordination message may include at least an indication of the set of resources.
