Abstract:
Techniques described herein may provide for the determination of the position of mobile devices based on information obtained through device-to-device (D2D) discovery or communications. Resource allocation schemes are described that allow efficient communication of signal location parameters, via D2D discovery, communications or newly defined physical channels, that may be used to estimate the position (or improve position estimation) of the mobile device.
Abstract:
Various embodiments herein provide techniques related to hybrid automatic repeat request (HARQ) feedback of a new radio (NR) sidelink (SL) transmission. Specifically, in embodiments, a user equipment (UE) may perform, in a first slot of a plurality of slots, a listen before talk (LBT) procedure related to a NR SL transmission. The UE may further identify a subset of two or more candidate slots of the plurality of slots for transmission of a HARQ message related to the LBT procedure. The UE may further transmit the HARQ message in a candidate slot of the two or more candidate slots. Other embodiments may be described and/or claimed.
Abstract:
Systems for providing prioritization of UL transmissions in a UE are described. The prioritization information is used to resolve resource conflicts among UL transmissions that include conflicts between high priority UL transmissions, between an aperiodic-channel state information transmission and a scheduling request, and between a low priority UL transmission and a high priority UL transmission when timeline conditions for multiplexing in a single UL transmission are not met. The prioritization is based on timing and priority of the UL transmissions to determine which of the UL transmissions to transmit and which to cancel. Additional prioritization is based on reception by the UE of a cancelation index or in an additional overlapping high priority UL grant received in a DCI of a PDCCH that overlaps with at least one other PDCCH associated with the UL transmissions.
Abstract:
Methods, systems, and storage media are described for the prioritization of services for control and data transmission for new radio (NR) systems. In particular, some embodiments may be directed to the prioritization of hybrid automatic repeat request-acknowledgment (HARQ-ACK) transmissions. Other embodiments may be described and/or claimed.

Abstract:
Various embodiments herein provide techniques related to methods or techniques to be performed by a user equipment (UE). In some embodiments, a technique may include identifying that a failure of a listen-before-talk (LBT) procedure is related to alignment with a u-FFP. The technique may further include notifying, based on the identification, a higher layer about the failure of the LBT procedure. Other embodiments may be described and/or claimed.
Abstract:
Various embodiments herein provide techniques for sending and receiving inter-user equipment (UE) coordination information for sidelink communication. The inter-UE coordination information may be provided via sidelink control information (SCI) and/or medium access control-control element (MAC-CE). Aspects regarding resource reservation and/or indication for UE coordination information are described. Additionally, new SCI formats for inter-UE coordination information are provided. Other embodiments may be described and claimed.
Abstract:
Various embodiments herein provide techniques for handling overlap of uplink (UL) channels (e.g., UL control channels and/or UL data channels), such as prioritizing and/or multiplexing uplink channels. In some embodiments, the overlapped channels may have different priorities. Other embodiments may be described and claimed.
Abstract:
An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for New Radio (NR) vehicle-to-everything (V2X) sidelink communication. The processing circuitry is to decode radio resource control (RRC) signaling from an authorized V2X network entity. The RRC signaling including configuration information to activate a sidelink transmit (TX) bandwidth part (BWP) of a plurality of sidelink TX BWPs within a sidelink carrier. Data is encoded for transmission to a second UE using a first sidelink signal. The processing circuitry is to cause transmission of the encoded data via the first sidelink signal. A bandwidth of the first sidelink signal during the transmission is within the activated sidelink TX BWP.
Abstract:
Embodiments of a user equipment (UE) configurable for unlicensed band operation in a 5G NR system (5GS), when operating in semi-static channel access mode, for a UE-initiated channel-occupancy time (COT), is configured to transmit an uplink (UL) transmission burst, as an initiating device, starting at a beginning of fixed frame period (FFP) and ending at a symbol before an idle period of the FFP after a successful clear-channel assessment (CCA).
