Methods, systems, and devices for transmit power control for positioning using non-serving cells are described. A user equipment (UE) may determine that an uplink reference signal may be associated with a positioning procedure. In some cases, the positioning procedure may include transmission, by the UE, of the reference signal to a non-serving cell, which may be farther away from the UE than a serving cell. The UE may determine an absence of a parameter associated with a transmit power for transmitting the reference signal. Based on the absence, the UE may determine the transmit power based on parameters received from a serving cell, based on configuration information, based on a message intercepted from the non-serving cell, or based on other considerations or information. In some cases, the UE may determine the transmit power such that the likelihood of the non-serving cell receiving the reference signal is increased.

A terminal node for a radio network comprising means for: receiving multiple positioning reference signals transmitted from respective transmission reception points of a network; determining time of arrival of the multiple positioning reference signals received from the respective transmission reception points; measuring at least a received signal quality metric for the multiple received positioning reference signals; processing, at least the multiple respective received signal quality metrics for the multiple received positioning reference signals, to trigger a received signal quality decision; and in response to the received signal quality decision, informing the network. A node of a radio network comprising means for: enabling transmission of multiple positioning reference signals from respective transmission reception points of a network; being informed of a received signal quality decision made at the terminal node in respect of measured received signal quality metrics for the transmitted positioning reference signals received at the terminal node; and in response, causing adaptation of transmission of signals in the network.

The present disclosure relates to a positioning method in a wireless communication system and a device supporting same.

A wireless device (12A) is configured to determine, for each of one or more links (14), one or more characteristics associated with wireless device positioning performance on the link. In some embodiments, the one or more characteristics include one or more of: geometric dilution of precision, GDOP, characteristics associated with the link; or line-of-sight, LOS, characteristics or non-LOS characteristics of the link. Regardless, the wireless device (12A) may also be configured to transmit control signaling (22) indicating the one or more characteristics determined for each of the one or more links (14). Based on this control signaling (22), a network node (16) may adapt positioning reference signal, PRS, configuration on at least one of the one or more links (14).

Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits a request for a first set of base stations to transmit on demand positioning reference signals (PRS) in a first band, measures the on demand PRS from the first set of base stations in the first band, measures periodic PRS from a second set of base stations operating in a second band, and sends, to a positioning entity, positioning measurements of at least the on demand PRS and the periodic PRS.

A low-power-consumption positioning method includes an electronic device sending first setting information to a server, where the first setting information is used to indicate the server to broadcast positioning assistance data to the electronic device at a first time interval (for example, 1 second). The electronic device resolves high-precision positioning information based on the positioning assistance data. When the electronic device meets a first preset condition, the electronic device may send second setting information to the server. The second setting information instructs the server to broadcast the positioning assistance data to the electronic device at a second time interval (for example, 60 seconds). The first time interval is shorter than the second time interval.

Disclosed in various embodiments of the present disclosure are a method for positioning in a wireless communication system, and a device for supporting same.

To obtain a relative localization between a plurality of mobile devices, a first mobile device observes a second mobile device within a field of view of the first mobile device's camera at time t1, determines a first position of the first mobile device at t1, and receives from the second mobile device a second position of the second mobile device at t1. The first mobile device determines information about the first mobile device's orientation with respect to the second mobile device at t1 based at least in part on the first position and the observation of the second mobile device. The first mobile device identifies two constraints that relate the mobile devices' coordinate systems based at least in part on the second position and the orientation information. The first mobile device's pose relative to the second mobile device may be calculated once at least six constraints are accumulated.

A satellite signal receiving device includes a first RF receiving circuit receiving a first satellite signal from a first GNSS, a second RF receiving circuit receiving a second satellite signal from a second GNSS, a baseband processing circuit processing the first satellite signal and the second satellite signal, and one or more processors configured to control operations of the first RF receiving circuit, the second RF receiving circuit, and the baseband processing circuit, in which the one or more processors are configured to execute performing reception processing of the first satellite signal, acquiring a first reception state including a processing result of the reception processing of the first satellite signal, determining processing capacity of reception processing of the second satellite signal depending on the first reception state, and performing the reception processing of the second satellite signal with the processing capacity.

Techniques are provided for time-domain processing of DL-PRS signals under certain conditions in which time-domain processing has a computational advantage over frequency-domain processing. Because of this, embodiments can provide positioning at a lower computational cost than positioning provided by traditional techniques utilizing only frequency-domain processing. This reduced computational cost can improve the battery life of mobile devices, ultimately resulting in a better user experience.
