For facilitating understanding of any embodiment of the present disclosure, first, a relative positioning scenario between terminals is explained, in order to support direct communication between terminals, a sidelink communication manner is introduced.

In one embodiment, in the sidelink communication mode, a sidelink interface between terminals is PC-5.

In one embodiment, in the sidelink communication scheme, the allocation scheme of the transmission resources includes:

the first mode is as follows: network dynamically scheduling transmission resources;

alternatively, the first and second electrodes may be,

the second mode is as follows: the terminal autonomously selects transmission resources in a resource pool broadcasted by the base station.

In one embodiment, the base station may dynamically allocate transmission resources of sidelink to the terminal according to a request of the terminal.

In one embodiment, the terminal may randomly select a sidelink transmission resource from a resource pool broadcasted or preconfigured by the base station.

In one embodiment, sidelink is used for wireless communication when relative positioning is carried out between terminals.

In an embodiment, when the terminal acquires the transmission resource in the second manner during the sidelink communication, a plurality of terminals may collide with the resource during the sidelink communication using the resource, resulting in a transmission collision.

In one embodiment, a collision avoidance mechanism is introduced for collisions of resources occurring in sidelink communications. Collision avoidance mechanisms can minimize this occurrence.

In one embodiment, the collision avoidance mode includes at least one of: a resource reservation mode, a resource reservation sensing mode, and a Listen Before Talk (LBT) mode.

In one embodiment, a terminal in an RRC idle state or an RRC inactive state needs to read a broadcast message of a base station, and if the broadcast message includes a sidelink communication resource pool, the terminal sends sidelink data in an autonomous selection manner, otherwise, the terminal needs to enter an RRC connected state, and the terminal sends sidelink resource request information to the base station to obtain a transmission resource for sidelink communication.

In one embodiment, a terminal in an RRC connected state needs to send a direct link terminal information (SidelinkUEInformation) message to a base station, where the SidelinkUEInformation message includes sidelink sending resource request information.

In one embodiment, the sidelink resource request information may correspond to a list, where the list includes a plurality of elements, and each element in the list may be information of a sidelink transmission characteristic, where the information includes a sidelink identifier, a transmission mode, a Quality of Service (QoS), and a target transmission frequency of the peer.

In an embodiment, if the first method is adopted, the terminal sends a sidelink Buffer Status Report (BSR) link control layer (MAC) Control Element (CE) to the base station, where the BSR MAC CE carries an opposite terminal identifier and a corresponding buffer status, and the opposite terminal identifier is used to indicate a sidelink identifier of an opposite terminal in the sidelink ueinformation message.

In one embodiment, the base station may configure a sidelink reception resource pool to the terminal through a broadcast or an RRC message, and the terminal performs sidelink communication on resources in the reception resource pool.

In one embodiment, the quality of service of the relative positioning traffic is affected by the available relative signaling resources. For example, it may be affected by the transmission bandwidth.

In one embodiment, when the terminal performs relative positioning, the terminal is started to send an ultra-narrow pulse as an initial relative positioning signal. And the feedback terminal feeds back an ultra-narrow pulse serving as a feedback relative positioning signal after receiving the ultra-narrow pulse. The initiating terminal calculates the relative distance between the two terminals based on the time difference between the two signals. The terminal calculates a relative Angle by measuring an Angle of Arrival (AOA) of the relative positioning signal. The relative positioning between the terminals is performed by the relative distance and the relative angle.

Since the resources used for sidelink communication are authorized frequencies of the operator, the resources are reused. As such, there is a need for a network that can control terminals to use resources in an orderly manner to reduce interference to other terminals for wireless communications.

As shown in fig. 2, a method for determining transmission resources of a relative positioning signal is provided in the embodiments of the present disclosure, and is applied to a base station, where the method includes:

step 21, sending resource configuration information;

the resource configuration information is used for the terminal to determine the transmission resource for transmitting the relative positioning signal.

In one embodiment, the relative positioning signal is a signal used to measure the relative position between the first terminal and the second terminal at the time of relative positioning.

The terminal may be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a Road Side Unit (RSU), a smart home terminal, and/or an industrial sensing device.

The base station is an interface device for the terminal to access the network.

The base stations can be of various types, such as base stations of a third generation mobile communication (3G) network, base stations of a fourth generation mobile communication (4G) network, base stations of a fifth generation mobile communication (5G) network, or other evolved base stations.

In one embodiment, measuring the relative position between the first terminal and the second terminal may be measuring the distance between the first terminal and the second terminal and/or the azimuth angle of the second terminal relative to the first terminal.

For example, referring to fig. 3, the measurement of the relative position between the mobile phone a and the mobile phone B may be the measurement of the distance d between the mobile phone a and the mobile phone B and the azimuth angle α of the mobile phone B relative to the mobile phone a.

In one embodiment, the relative position between the first terminal and the second terminal may be determined by measuring relative positioning signals transmitted on sidelink.

In one embodiment, the transmission resource may be a resource for the terminal to receive the relative positioning signal, or may be a resource for the terminal to transmit the relative positioning signal.

In one embodiment, the transmission resources may be time and/or frequency domain resources on a licensed frequency band.

In one embodiment, please refer to fig. 3 again, the first terminal is terminal a, and the second terminal is terminal B. When the relative positioning between the terminal A and the terminal B is carried out, the terminal A is started to send a super-narrow pulse as an initial relative positioning signal based on sidelink. And the feedback terminal B feeds back an ultra-narrow pulse as a feedback relative positioning signal after receiving the initial relative positioning signal. The initiating terminal a calculates the relative distance d between terminal a and terminal B based on the time difference between sending the initial relative positioning signal and receiving the feedback relative positioning signal. Terminal a calculates the relative angle a by measuring the AOA feeding back the relative positioning signal. The relative positioning between the terminals a and B is performed by the relative distance d and the relative angle α to determine the relative position between the first terminal a and the second terminal B.

In one embodiment, in response to a need for relative positioning between a first terminal and a second terminal, the first terminal or the second terminal may obtain a transmission resource for transmitting a relative positioning signal by sending a resource acquisition request to a base station.

In one embodiment, in response to receiving an acquisition request for acquiring resource configuration information sent by a terminal, a base station sends the resource configuration information for the acquisition request to the terminal.

In one embodiment, in response to the channel quality of the relative positioning signal transmission performed by the terminal being less than the quality threshold, the terminal sends an acquisition request to the base station for acquiring the resource configuration information. Here, the relative positioning signal may be transmitted by using a randomly selected transmission resource from a resource pool.

In one embodiment, in response to the terminal establishing an RRC connection with the base station, the terminal may send an acquisition request to the base station requesting acquisition of the resource configuration information.

In one embodiment, in response to the terminal starting a relatively positioned application, the terminal may send an acquisition request to the base station requesting acquisition of the resource configuration information.

Thus, the terminal can obtain the transmission resource for transmitting the relative positioning signal in time.

In one embodiment, resources can be scheduled through a uniform resource scheduling algorithm, interference caused by resource collision when relative positioning signals are transmitted between different terminals is reduced, and channel communication quality is improved.

In one embodiment, the base station may broadcast a resource pool to the terminals, and the terminals may transmit relative positioning signals on randomly selected transmission resources in the resource pool.

In one embodiment, a resource pool may be preconfigured, and the terminal may transmit the relative positioning signal on a randomly selected transmission resource in the preconfigured resource pool.

In one embodiment, in order to reduce resource collision caused by random selection of resources from a resource pool by each terminal for sidelink wireless communication, a collision avoidance function may be activated. Here, the collision avoidance function includes at least one of: resource reservation, resource reservation sensing, and LBT.

In one embodiment, the resource configuration information may indicate transmission resources for the terminal to transmit the relative positioning signal.

For example, the resource configuration information may carry time domain position and/or frequency domain position information of the transmission resource.

In one embodiment, the resource configuration information may indicate an acquisition manner of acquiring transmission resources for the terminal to transmit the relative positioning signal.

For example, the resource configuration information may carry indication information indicating that the transmission resource is acquired from the resource pool.

In one embodiment, the resource configuration information indicates both transmission resources for the terminal to transmit the relative positioning signal and a manner of acquiring the transmission resources from the resource pool.

In an embodiment, if the base station deploys an area with a low density (e.g., a mountain area, an ocean, or the like), and the resource configuration information indicates both a transmission resource for the terminal to transmit the relative positioning signal and a manner of acquiring the transmission resource from the resource pool, when the terminal performs relative positioning by using sidelink, the transmission resource selected from the resource pool is preferentially used to transmit the relative positioning signal.

In some embodiments, the base station sends the resource configuration information via a broadcast message; or, the base station sends the resource configuration information through the RRC reconfiguration message.
