Systems and methods for configuring and performing compensation for UE clock drifts and/or UE timing adjustments for RTT estimations. A wireless device can receive, from a network node, configuration information associated with estimating and reporting transmission timing compensation. The wireless device can estimate a transmission timing compensation for a time interval and report it to the network node. The network node can estimate a round trip time and/or a position of the wireless device based at least in part on the estimated transmission timing compensation.

A method and devices are disclosed for geo-location of wireless local area network (WLAN) devices. According to one aspect, a method for determining a corrected round trip times (RTT) resulting from communication with a WD is provided. The WD is configured with one or two short interframe spacings (SIFS). The method includes performing RTT measurements at successive times. The method includes determining a presence of one or two modes based at least in part on peaks of a kernel density estimation (KDE) surface. The KDE surface is determined from the RTT measurements. When there is only one mode, a corrected RTT is determined based on the RTT measurements and a first SIFS. When there are two modes, a corrected RTT is determined based on the RTT measurements and the first SIFS plus an SIFS offset (), being based at least in part on a difference between the two modes.

The invention relates to a method for handover of a transceiver equipment, in particular UE and/or on-board equipment (OBE), from a serving cell to a target cell in a cellular communications network, said serving cell belonging to a first base station and said target cell belonging to a second base station, and said target cell being selected from a group of neighbor cells being better than the serving cell by an offset, wherein the method comprises: I. transmitting a measurement report to the first base station, said measurement report comprising information on a neighbor cell selected from the group of neighbor cells, based on i. a distance criterion, and optionally ii. a trajectory criterion, II. receiving a handover command from the first base station, said handover command comprising instruction for handover to the selected neighbor cell becoming the target cell, and III. completing handover with the second base station.

Techniques are provided for reducing signaling latency in multi-link devices (MLDs). An example method of providing latency sensitive information with a MLD includes receiving downlink data packets from a station via a first radio link, performing radio frequency sensing with a second radio link, detecting a latency sensitive event, and transmitting an indication of the latency sensitive event.

Accurate and reliable time is acquired by a user equipment (UE) from a base station in a wireless network. The base station may obtain the time, e.g., UTC time or a GNSS time, and ciphers at least a portion of the time before broadcasting the time. The UE determines a propagation delay between the UE and the base station based on a timing advance, known locations of the UE and the base station, or a measured round trip propagation time (RTT) between the UE and the base station. A corrected time can be determined based on the time received from the base station and the propagation delay. A digital signature included with the time broadcast by the base station increases reliability. Spoofing of the broadcast time by an attacking device may be detected by the UE based on the propagation delay being outside an expected range.
