Abstract:
Technology for adapting uplink-downlink (UL-DL) time-division duplexing (TDD) subframe configurations in a heterogeneous network (HetNet) is disclosed. One method can include a reference enhanced Node B (eNB) determining a preferred adaptive UL-DL configuration. The eNB can receive node configuration information for at least one neighboring node. The eNB can reconfigure an adaptive UL-DL configuration for at least one of the reference eNB and the at least one neighboring node based on the node configuration information and sounding reference signal (SRS) subframe scheduling of the reference eNB and the at least one neighboring eNB.
Abstract:
Various embodiments herein provide techniques for configuring and/or using a measurement gap (MG) for a positioning reference signal (PRS) measurement. For example. a user equipment (UE) may receive a configuration of a pre-configured measurement gap; identify that a measurement gap is needed for a positioning reference signal (PRS) measurement and that the CE has not previously notified a network of the PRS measurement prior to receipt of the configuration; and encode, based on the identification, a location measurement indication for transmission to a network entity to indicate that the PRS measurement is to be performed. Other embodiments may be described and claimed.
Abstract:
An apparatus and system of enabling reference signal measurements in a non-terrestrial network (NTN) system are described. The UE provides capability information that indicates a maximum number of synchronization signal block (SSB)-based measurement timing configurations (SMTCs) simultaneously supported by the UE for measurement of reference signals from cells in the NTN system and receives SMTCs based on the capability information and a real time estimate of timing differences among the cells. The UE sends/receives data based on the SMTCs and whether the UE supports simultaneous data communication and measurement. Broadcast system information contains a flag that indicates which of dynamic and semi-static configuration is used, the maximum SMTC's dependent on the flag value. Radio resource control (RRC) signalling is used to send sets of SMTCs that have different offsets. Different sets are activated using dynamic signaling according to real time estimates of the timing differences.
Abstract:
An apparatus and system for inter-UE coordination feedback for sidelink communications are described. In particular, inter-UE coordination feedback signaling for reliable sidelink communication including transmitter-based resource allocation and signaling of conflicts, prioritization of the inter-UE coordination feedback, and timing of the inter-UE coordination feedback are described. Sidelink hybrid acknowledgment request (HARQ) acknowledgment/negative acknowledgment (ACK/NACK) or NACK only signaling is prioritized over a half-duplex (HD) or co-channel collision (CC) feedback indication, and uplink transmissions are prioritized over sidelink transmissions. In response to detection of a conflict, the inter-UE coordination feedback is transmitted relative to the slot where the HD or CC event occurs or relative to the slot where reservation of the resources for the sidelink transmissions.
Abstract:
An apparatus and system for determining positioning measurement accuracy are described. A UE receives positioning reference signals (PRS) from a reference cell and a neighbor cell and reference signal time difference (RSTD) measurements based on the PRS. RSTD and other PRS measurement results based on the reference and neighbor cells have RSTD and other PRS measurement accuracy requirements, that depend on bandwidth (BW), subcarrier spacing (SCS), and repetition factor of the PRS.
Abstract:
An apparatus of a New Radio (NR) Node B (gNB), a method, and a storage medium. One or more processors of the apparatus are to: encode for transmission to a user equipment (UE) a message to configure the UE with a measurement gap pattern for positioning reference signal (PRS) measurements; and set a gap pattern length of a measurement gap corresponding to the measurement gap pattern depending on whether an overlap exists between a PRS to be measured and one or more other NR data scheduled to be received by the UE.
Abstract:
Systems and methods provide solutions for delay and interruption requirements for vehicle-to-everything (V2X) sidelink carrier aggregation (CA). For example, when any number of component carriers is added for V2X CA, a user equipment (UE) capable of V2X sidelink communication is allowed an interruption of up to two subframes to the cellular network. The interruption may be for both uplink and downlink of a serving cell or primary cell.
Abstract:
Systems and methods provide for testing receiver (Rx) performance requirements of a user equipment (UE). Test equipment is configured to generate a radio frequency (RF) signal with a power level (Es) and determine a power spectral density (Noc) for an artificial noise signal. The Es and Noc may be selected to emulate a target signal-to-noise ratio (SNR) at a baseband Rx chain of the UE and to compensate for UE RF noise. The RF signal and the noise signal may be combined to produce an applied signal provided to the UE for testing.
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.

A bandwidth of the first sidelink signal during the transmission is within the activated sidelink TX BWP.
