    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.

    Abstract: A user equipment (UE) configured to determine a resource selection window which identifies a first set (e.g., a total set) of candidate resources. The UE may then remove one or more candidate resources from the first set of candidate resources in response to receiving sidelink control information (SCI) from a pedestrian UE with a reservation of the one or more first candidate resources. After removal of these candidate resources from the initial or first set based on their presumed unavailability, the result may be a second set of candidate resources, which may be a subset of the initial or first set for use in communicating with a third UE. The UE may also be configured to remove candidate resources based on a reference signal receive power (RSRP) threshold which can also be adjusted based on a maximum value or a highest priority of the pedestrian UE's data.
