  • PRS design by extending the basic signal
    Patent number: 11956168
    Abstract: A method, network node and wireless device for position reference signal (PRS) design by extending a base signal are disclosed. According to one aspect, a method in a wireless device (WD) includes obtaining extended reference signal, RS, configurations from the network node. The method also includes determining a waveform associated with the extended RS. The method also includes detecting a RS and estimate an associated time of arrival. The method further includes sending a measurement report to the network node based on the estimated time of arrival.

  • CIR Peak Threshold Control for TOA Estimation
    Publication number: 20230288547
    Abstract: A threshold condition formed relative to the strongest peak (e.g., in a signaled DL-PRS-specific search window) is used in the search for the first peak to be used for Time of Arrival (TOA) estimation. Such a threshold condition may be used with DL-PRSs that are homogenous or inhomogeneous, and in each of these combined (or not) with cyclic shifts. In so doing, the solutions 0 (100, 200, 300, 400) presented herein avoid detecting false peaks.

  • Narrowband positioning reference signal generation for correlation properties
    Patent number: 11567159
    Abstract: Systems and methods for configuring and generating Narrowband Positioning Reference Signals (NPRS) for NB-IoT are provided. A network node provides (NPRS) configuration information indicating a system frame number (SFN) dependent resource mapping. A wireless device obtains a NPRS in accordance with the indicated SFN dependent resource mapping and uses it to perform a radio measurement operation.

  • Methods and Apparatuses for Positioning Based on the Sounding Reference Signal
    Publication number: 20220123886
    Abstract: A method performed by a user equipment, UE (110, 200) includes obtaining (1202) a Sounding Reference Signal, SRS, configuration from a network node (160) and determining (1204) an SRS waveform and transmitting (1206) the SRS waveform. The SRS waveform is adapted for positioning based on the SRS configuration to have a full bandwidth within a bandwidth applicable for the SRS waveform.

  • Industrial Automation with 5G and Beyond
    Publication number: 20200259896
    Abstract: Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.
