Abstract:
A computer-readable storage medium stores instructions to configure a UE for NR positioning in a 5G NR network, and to cause the UE to perform operations including decoding configuration signaling received from a location and management function (LMF) node of the 5GNR network. The configuration signaling includes a positioning reference signal (PRS) measurement configuration. A number of measurement samples per a successful measurement reporting can be indicated by the PRS measurement configuration which depends on a specific conditions (e.g., PRS bandwidth, propagation channel, and SINR). A PRS received from a base station is decoded. Downlink PRS (DL-PRS) positioning measurements is performed based on the PRS. The DL-PRS positioning measurements are encoded for transmission to the LMF node using the number of measurement samples.
Abstract:
An apparatus and system for use of a pre-configured gap are described. The network signals a preconfigured gap via radio resource control (RRC) signaling and follows a bandwidth part (BWP) to activate/deactivate the gap upon BWP switching. The RRC signaling indicates whether a measurement gap is a pre-configured gap. Pre-configured frequency range 1 (FR1) and FR2 gaps are able to be configured simultaneously using RRC signaling. Similarly, legacy gaps and pre-configured gaps are able to be configured simultaneously using RRC signaling. The pre-configured gap may be autonomously or implicitly activated triggered by downlink control information (DCI) or timer-based BWP switching—in some cases under predetermined network conditions.
Abstract:
An apparatus and system for setting an uplink timing advance (TA) for a non-terrestrial network (NTN) user equipment (UE) are described. The NTN UE estimates and updates a UE-specific TA value each period. The update is based on Global Navigation Satellite System (GNSS) positions and satellite ephemeris information. The NTN UE adjusts the UE-specific TA gradually, between a predetermined minimum and maximum aggregate adjustment rate.
Abstract:
In a fifth-generation (5G) new radio (NR) network, a generation node B (gNB) determines parameters for a Network Controlled Small Gap (NCSG) to reduce and/or eliminate interruptions at a user equipment (UE) for use when the UE is transitioning to a new target frequency for measurements or when the UE is switching or transiting between bandwidth parts (BWPs). The NCSG may be configured to align with one or more fundamental parameters of a legacy measurement gap (MG) pattern to reduce the interruptions.
Abstract:
Various embodiments herein provide techniques for positioning measurements in a wireless cellular network when a user equipment (UE) is in a radio resource control (RRC) inactive state or a RRC idle state. For example, the UE may transmit a sounding reference signal (SRS) for positioning measurements while the UE is in the RRC inactive state or RRC idle state. The SRS may be a semi-persistent SRS and may be transmitted after an activation delay from receipt of a message (e.g., medium access control (MAC) control element (CE)) that activates the SRS. Additionally, or alternatively, the UE may perform a positioning reference signal (PRS) measurement while in the RRC inactive state or the RRC idle state. The PRS measurement may have a reduced number of measurement samples. Other embodiments may be described and claimed.

Abstract:
Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for device-to-device on-demand advertisement. In some embodiments, the method may include receiving a request for broadcasting an advertisement by a device-to-device (D2D) advertiser via a D2D communication protocol, requesting that an evolved NodeB (eNB) associated with the D2D advertiser allocate a resource for broadcasting the advertisement by the D2D advertiser, determining that the broadcasting the advertisement is no longer needed, and requesting that the eNB retrieve the allocated resource. Other embodiments may be described and claimed.
Abstract:
An apparatus and method that allow user equipment (UE) to transmit information directly with other user equipment, using a device-to-device (D2D) mode is disclosed herein. A first D2D UE (dUE1) that wishes so communicate to a second D2D UE (dUE2) in D2D mode makes various communications requests to an Evolved Node B (eNB), which can facilitate the connection between the dUE1 and the dUE2. Among these requests are to make the D2D connection via WiFi instead of via Long Term Evolution (LTE). The eNB determines the WiFi capabilities of dUE1 and dUE2, then assigns a subset of available channels to be scanned by dUE1 and a separate subset of available channels to be scanned by dUE2. Thereafter, the eNB can assign a WiFi channel based on the scans performed by dUE1 and dUE2.
Abstract:
Embodiments herein provide techniques and requirements for radio resource management (RRM) measurements. For example, embodiments include techniques and requirements associated with: channel state information (CSI)-reference signal (RS) based inter-frequency RRM measurements when the CSI-RS bandwidth and the active downlink (DL) bandwidth part (BWP) are partially overlapped; adaptive RRM CSI-RS configuration and DL gap allocation by user equipment (UE) capability indication; and/or neighboring cell RRM CSI-RS measurement requirements when serving cell RRM CSI-RS is not configured. Other embodiments may be described and claimed.
