[0001] Priority Declaration

[0002] This application claims priority to the Chinese patent application filed on July 1, 2022, with application number 202210775178.8, and invention name “Electronic device and method for wireless communication system”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates generally to electronic devices and methods for use in wireless communication systems, and particularly to techniques for wireless sidelink communications. Background Art

[0004] Wireless communication systems can use a variety of protocols and standards for data transmission between devices. These protocols and standards have undergone long-term development and include, but are not limited to, the Third Generation Partnership Project (3GPP), 3GPP Long Term Evolution (LTE) (e.g., 4G communications), 3GPP New Radio (NR) (e.g., 5G communications), and the IEEE 802.11 standard for wireless local area networks (WLANs), also commonly known as Wi-Fi.

[0005] As an example, in an LTE or NR system, the communication interface between user devices (also referred to herein as terminal devices) includes a PC5 interface. The PC5 interface can be used for vehicle-to-everything (V2X) communication (which may include vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, vehicle-to-network (V2N) communication, vehicle-to-pedestrian (V2P) communication, etc.), device-to-device (D2D) communication, and other scenarios in which communication can be performed directly between user devices. On this communication interface, the user device can perform wireless data transmission via a side link (SL). Specifically, the terminal device can use an antenna panel mounted thereon to send and receive reference signals. In some scenarios, the reference signal can be used to implement functions such as positioning. Therefore, it is hoped to find a system and method that can effectively utilize antenna panels to send and receive reference signals to improve positioning performance.

DETAILED DESCRIPTION

[0029] The following describes representative applications of various aspects of the apparatus and method of the present disclosure. The description of these examples is only to add context and help understand the described embodiments. Therefore, it is clear to those skilled in the art that the embodiments described below can be implemented without some or all of the specific details. In other cases, well-known process steps are not described in detail to avoid unnecessarily obscuring the described embodiments. Other applications are also possible, and the solutions of the present disclosure are not limited to these examples.

[0030] In this disclosure, to facilitate description of the technical solutions involved in the embodiments, terms such as "first" and "second" are used to distinguish between identical or similar items having substantially the same functions and effects. Those skilled in the art should understand that terms such as "first" and "second" do not limit the quantity, order of execution, or priority order, and do not necessarily mean that "first" and "second" are different.

[0031] Typically, a wireless communication system may include network equipment and user equipment, and the network equipment may provide communication services for one or more user equipment.

[0032] In the present disclosure, the term "network device" (or "base station", "control device") has the full breadth of its usual meaning and includes at least a wireless communication station that is part of a wireless communication system or radio system to facilitate communication. As an example, the network device can be, for example, an eNB of the 4G communication standard, a gNB of the 5G communication standard, a remote radio head, a wireless access point, a drone control tower, or a communication device that performs similar functions. In the present disclosure, "network device", "base station" and "control device" can be used interchangeably, or the "network device" can be implemented as part of a "base station". The following application examples will be described in detail with reference to the accompanying drawings using the network device as an example.

[0033] In the present disclosure, the term "user equipment (UE)" or "terminal device" has the full breadth of its usual meaning and includes at least a terminal device that is part of a wireless communication system or a radio system to facilitate communication. As an example, the user equipment can be, for example, a mobile phone, a laptop, a tablet computer, an in-vehicle device (e.g., a car, a bicycle, an electric car, an airplane, a ship, a train, a high-speed rail, etc.), a virtual reality device, a workshop device, a wireless device in an unmanned driving, a wearable device, a sensor, etc., or an element thereof. In the present disclosure, "user equipment" (hereinafter referred to as "UE") and "terminal device" can be used interchangeably, or "user equipment" can be implemented as a part of a "terminal device".

[0034] In the present disclosure, the term "transmitter" has the full breadth of its usual meaning and generally refers to the side of a communication system that sends data, which can be a network device / base station side or a user device / terminal device side. Similarly, the term "receiver" has the full breadth of its usual meaning and can accordingly refer to the side of a communication system that receives data, which can be a user device / terminal side or a network device / base station side. In the following, the example in which both the transmitter and the receiver are user devices is used for explanation, but this should not be understood as a limitation of the present disclosure. In addition, in the present disclosure, the same device can act as both a transmitter and a receiver.

[0035] Figure 1 shows an example scenario diagram of sidelink communication in a wireless communication system according to an embodiment of the present disclosure. It should be understood that Figure 1 only illustrates one of the many types and possible arrangements of wireless sidelink communication systems; the features of the present disclosure can be implemented in any of the various systems as needed.

[0036] As shown in Figure 1, sidelink communication in a wireless communication system 100 involves communication between multiple user devices. For ease of understanding and simplified description, Figure 1 shows two user devices: a first user device (shown as "UE1" in Figure 1) and a second user device (shown as "UE2" in Figure 1). The first user device and the second user device can communicate directly without going through a network device (i.e., both the transmitting end and the receiving end are user devices), and the communication link between the two is called a sidelink. It should be understood that the first user device and the second user device can be devices of the same type or different types.

[0037] In sidelink communication, the user equipment can send and receive reference signals through the antenna panel to achieve functions such as positioning. For example, in Figure 1, each user equipment (for example, the first user equipment or the second user equipment) can be installed with one or more antenna panels, and the one or more antenna panels can be installed at one or more locations on the user equipment. As an example, Figure 1 shows a scenario in which UE1 and UE2 each have two antenna panels. Specifically, the first user equipment has a first antenna panel (shown as "AP1" in Figure 1) and a second antenna panel (shown as "AP2" in Figure 1), while the second user equipment has a third antenna panel (shown as "AP3" in Figure 1) and a fourth antenna panel (shown as "AP4" in Figure 1). For example, UE1 can receive reference signals sent from AP3 and AP4 of UE2 through AP1. For example, in some embodiments, the reference signal can be a synchronization reference signal or a positioning reference signal, which can be used to achieve functions such as positioning, such as determining the relative position relationship between UE1 and UE2.

[0038] It should be understood that the scenario in Figure 1 is merely an example, and a greater number of user devices may exist in the communication system. It should also be understood that each user device may have a greater or fewer number of antenna panels. Although the antenna panels shown in Figure 1 are located at the front and rear of the user device, in practice, the antenna panels may be installed at any location on the user device, including but not limited to the front (or head), rear (or tail), middle, top, bottom, left, right, etc. of the user device.

[0039] According to Figure 1, when the first user equipment and the second user equipment cannot know the position of the antenna panel from which the reference signal from the other party originates, the positioning performance may be greatly affected. For example, UE1, as a receiving end, can receive the reference signal from AP3 of UE2 through AP1, and can also receive the reference signal from AP4 of UE2 through AP1. If the size of UE2 itself is large, then the positions of AP3 and AP4 on UE2 are likely to be far apart, so that the distance between the two user equipment measured and estimated by the two is quite different. As an example and not a limitation, when UE1 and UE2 are both vehicles, the normal driving distance d between the two user equipment can be more accurately measured or estimated by using AP1 of UE1 and AP4 of UE2 to send / receive the reference signal, otherwise a distance error of the vehicle body length will likely be generated. This distance error is particularly serious when the distance between the two user equipment is small, which reduces the accuracy of positioning.

[0040] To improve positioning performance in sidelink communications, embodiments of the present disclosure associate (e.g., map) the time and frequency resources of a reference signal with the installation location of the antenna panel transmitting the reference signal on the transmitting user equipment. Consequently, a receiving user equipment receiving the reference signal can determine the location of the antenna panel transmitting the reference signal based on the predetermined association and the time and frequency resources occupied by the reference signal, thereby performing corresponding operations or calculations to ensure more accurate positioning performance.

[0041] Figure 2 shows an exemplary electronic device for a first user equipment in a wireless communication system according to an embodiment of the present disclosure. The electronic device 200 shown in Figure 2 may include various units to implement various embodiments according to the present disclosure. In this example, the electronic device 200 includes a communication unit 202 and a control unit 204. In one embodiment, the electronic device 200 is implemented as the first user equipment itself or a portion thereof, or as a device related to the first user equipment or a portion thereof. The various operations described below in conjunction with the first user equipment may be implemented by units 202 and 204 of the electronic device 200 or other possible units.

[0042] In an embodiment, the first user equipment may have one or more antenna panels installed (or attached thereto). The communication unit 202 of the electronic device 200 of the first user equipment may receive a reference signal transmitted by a third antenna panel installed thereon of the second user equipment through the first antenna panel installed on the first user equipment, wherein the time resources and / or frequency resources occupied by the reference signal are associated with the position of the third antenna panel on the second user equipment. The control unit 204 of the electronic device may determine the position of the third antenna panel on the second user equipment based on the association relationship between the position of the third antenna panel on the second user equipment and one or more time resources and / or frequency resources and the time resources and / or frequency resources occupied by the above-mentioned received reference signal.

[0043] Figure 3 shows an exemplary electronic device 300 for a second user equipment in a wireless communication system according to an embodiment of the present disclosure. The electronic device 300 shown in Figure 3 may include various units to implement various embodiments according to the present disclosure. In this example, the electronic device 300 includes a communication unit 302 and a control unit 304. In one embodiment, the electronic device 300 is implemented as the second user equipment itself or a portion thereof, or as a device related to the second user equipment or a portion thereof. The various operations described below in conjunction with the second user equipment may be implemented by units 302 and 304 of the electronic device 300 or other possible units.

[0044] In an embodiment, the second user equipment may be installed with (or attached with) one or more antenna panels. The communication unit 302 of the electronic device 300 of the second user equipment may send a reference signal to the first user equipment via a third antenna panel installed on the second device user, wherein the time resources and / or frequency resources occupied by the reference signal are associated with the position of the third antenna panel on the second user equipment. The above operation may enable the first user equipment to determine the position of the third antenna panel on the second user equipment based on the association relationship between the position of the third antenna panel on the second user equipment and one or more time resources and / or frequency resources and the time resources and / or frequency resources occupied by the reference signal sent above.

[0045] It should be understood that the control unit 304 of the electronic device 300 may instruct the communication unit 302 to pre-notify the first user equipment of the association relationship between the position of the third antenna panel on the second user equipment and one or more time resources and / or frequency resources. Alternatively, the above-mentioned association relationship may be determined by default, or may be pre-determined by the network device and then notified to each user equipment in the wireless communication system.

[0046] In some embodiments, electronic devices 200 and 300 may be implemented at the chip level, or may be implemented at the device level by including other external components (eg, radio links, antennas, etc.). For example, each electronic device may function as a communication device as a whole.

[0047] It should be noted that the above-mentioned units are only logical modules divided according to the specific functions implemented by them, rather than being used to limit the specific implementation mode. For example, they can be implemented in software, hardware or a combination of software and hardware. In actual implementation, the above-mentioned units can be implemented as independent physical entities, or can also be implemented by a single entity (for example, a processor (CPU or DSP, etc.), an integrated circuit, etc.). Among them, the processing circuit can refer to various implementations of a digital circuit system, an analog circuit system or a mixed signal (a combination of analog and digital) circuit system that performs functions in a computing system. The processing circuit may include, for example, circuits such as an integrated circuit (IC), an application-specific integrated circuit (ASIC), part or circuit of a separate processor core, an entire processor core, a separate processor, a programmable hardware device such as a field programmable gate array (FPGA), and / or a system including multiple processors.

[0048] The relationship between time-frequency resources and antenna panel positions

[0049] According to an embodiment of the present disclosure, an association relationship (sometimes also referred to as a mapping relationship) is established between the time resources and / or frequency resources of a reference signal and the installation location of the antenna panel that sends the reference signal on the transmitting end user equipment. In other words, the time resources and / or frequency resources occupied by the reference signal can indicate the specific location (or relative location) of the antenna panel that sends the reference signal. Based on this association relationship, the receiving end user equipment that receives the reference signal can quickly and accurately determine the location of the antenna panel that sends the reference signal on the transmitting end user equipment based on the time resources and / or frequency resources occupied by the reference signal.

[0050] Figure 4 shows an example diagram of the association relationship between the reference signal time-frequency resources and the antenna panel position according to an embodiment of the present disclosure. In this example, it is assumed that the user device has two antenna panels installed at the front and rear, respectively, which are referred to as the front antenna panel and the rear antenna panel in the figure. It should be understood that the words "front" and "rear" in the present disclosure only represent relative positions. For example, the normal moving direction of the user device can be defined as "front", or the head position of the user device in the general sense can be defined as "front". As an example, in a scenario where the user device is a vehicle, the front antenna panel can be installed on the front bumper of the vehicle, and the rear antenna panel can be installed on the rear bumper of the vehicle.

[0051] As shown in Figure 4, a subframe in a wireless communication system may include 14 OFDM symbols. The horizontal axis in Figure 4 may represent time resources, the vertical axis may represent frequency resources, and a small square represents a resource element (RE). A resource element may be regarded as the smallest unit of time resources and / or frequency resources (sometimes referred to as time-frequency resources in this document), which corresponds to one OFDM symbol in the time domain and one subcarrier in the frequency domain. In the example of Figure 4, the reference signal transmitted by the front antenna panel is associated with the time-frequency resources represented by the resource element marked with vertical line shading, and the reference signal transmitted by the rear antenna panel is associated with the time-frequency resources represented by the resource element marked with diagonal line shading.

[0052] As previously mentioned, the aforementioned association relationship (or mapping relationship) can be pre-notified by the transmitting user equipment to the receiving user equipment in the form of a mapping table or the like. Alternatively, this association relationship can be determined by system default, or can be pre-determined by the network equipment and then notified to each user equipment. The notification message regarding the association relationship can be indicated via a physical layer message or via a higher layer message (such as a MAC layer message).

[0053] It should be understood that FIG4 merely illustrates an example of an association (or mapping) between antenna panel positions and one or more reference signal time-frequency resources. In practice, a transmitting user equipment may have a greater or lesser number of antenna panels located at one or more positions, and the position of each antenna panel may be associated only with a time resource, only with a frequency resource, or with both a time resource and a frequency resource.

[0054] Correspondingly, when the transmitting user equipment sends a reference signal, it needs to use the time-frequency resources corresponding to the position of the antenna panel on the user equipment according to the above-mentioned association relationship to send it. Optionally, the transmitting user equipment can use different resource sets (Resource Set) to determine the reference signals sent through antenna panels at different positions. Optionally, the transmitting user equipment can use different frequency layers (Frequency Layer) to determine the reference signals sent through antenna panels at different positions. After the transmitting user equipment sends the reference signal to the receiving user equipment, the receiving user equipment can determine the position of the antenna panel that sends the reference signal on the transmitting user equipment based on the association relationship between the antenna panel position and the time-frequency resources and the time-frequency resources occupied by the reference signal.

[0055] Positioning in sidelink communication

[0056] As described with reference to Figure 1, in wireless sidelink communications, appropriately selecting the antenna panels of the transmitting user device and the receiving user device to transmit and receive reference signals can improve positioning performance. Generally speaking, the operations involved in positioning in sidelink communications include, but are not limited to, determining the relative positional relationships of multiple user devices, measuring and estimating the distances between multiple user devices, and inferring whether there are any anomalies in the current positions or movements of multiple user devices. Accordingly, two examples of positioning in sidelink communications will be described below, focusing on these operations.

[0057] For ease of description and understanding, the following description of the technical solution of the present disclosure uses a sidelink communication scenario in which both the first user equipment and the second user equipment are vehicles as an example. However, the present disclosure is not limited to this specific type of communication between user equipments and is applicable to positioning scenarios in sidelink communication between multiple user equipments of various types.

[0058] First example of positioning in sidelink communication

[0059] In the first example of sidelink positioning, the second user device, primarily serving as a transmitter, can have multiple antenna panels, while the first user device, primarily serving as a receiver, can have a single antenna panel or utilize only one of the multiple antenna panels, thereby implementing a series of positioning-related operations. Figure 5 shows a schematic diagram of the first example of positioning in sidelink communication according to an embodiment of the present disclosure.

[0060] In Figure 5 , a first user equipment is shown as UE1, on which at least a first antenna panel (shown as AP1) is installed; a second user equipment is shown as UE2, on which at least a third antenna panel (AP3) and a fourth antenna panel (AP4) are installed. For purposes of example only and not limitation, AP1 in the figure is located in front of UE1, AP3 is located in front of UE2, and AP4 is located in the rear of UE2.

[0061] According to an embodiment of the present disclosure, the time resources and / or frequency resources occupied by the reference signal sent by AP3 are associated with the position of AP3 on UE2 (e.g., the front), and the time resources and / or frequency resources occupied by the reference signal sent by AP4 are associated with the position of AP4 on UE2 (e.g., the back). It should be appreciated that the association between the position of AP3 on UE2 and one or more time resources and / or frequency resources, and the association between the position of AP4 on UE2 and one or more time resources and / or frequency resources, can be determined by default or can be notified to UE1 in advance by UE2. Generally speaking, the one or more time resources and / or frequency resources associated with AP3 and the one or more time resources and / or frequency resources associated with AP4 are independent of each other and do not overlap. Accordingly, UE1 can receive the reference signal sent by AP3 (or AP4) of UE2 through AP1, and can determine the position of AP3 (or AP4) on UE2 based on the association between the antenna panel position and the time-frequency resources and the time-frequency resources occupied by the reference signal.

[0062] According to a first example of an embodiment of the present disclosure, the relative positions of the first user equipment (UE1) and the second user equipment (UE2) may be determined, for example, the relative position relationship may be determined.

[0063] As shown in Figure 5, a method for determining the relative position between UE1 and UE2 may include: UE1 receives a first reference signal sent by AP3 of UE2 through AP1, and UE1 receives a second reference signal sent by AP4 of UE2 through AP1. Based on the reception strength of the first reference signal and the second reference signal, the front and rear position relationship between UE1 and UE2 can be determined. Specifically, as shown in 500A, when the strength of the first reference signal is less than the strength of the second reference signal, since UE1 can determine the position of the antenna panel that sends the reference signal on UE2 based on the time resources and / or frequency resources of the received reference signal, it can be determined that UE1 is located behind UE2. Similarly, as shown in 500B, when the strength of the first reference signal is greater than the strength of the second reference signal, UE1 can determine that it is located in front of UE2.

[0064] It should be understood that the strength of the reference signal referred to in this article may include but is not limited to one or a combination of multiple of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), reference signal signal to interference and noise ratio (SINR), etc.

[0065] Alternatively, another method for determining the relative position between UE1 and UE2 may include using a satellite navigation positioning system (GPS) to roughly determine the front and back position relationship of the user equipment.

[0066] Further, based on the determined relative positions of UE1 and UE2, UE1 can receive a reference signal sent by an antenna panel in AP3 or AP4 of UE2 through AP1 to measure the distance between UE1 and UE2. As an example, when UE1 and UE2 are both vehicles traveling normally, the distance (vehicle distance) d between the two generally refers to the distance between the front of the rear vehicle and the rear of the front vehicle. Specifically, as shown in 500A, when it is determined that UE1 is located behind UE2, the distance d between the two user devices can be measured and estimated by UE1 by receiving a reference signal sent from AP4 of UE2 through AP1 (because AP4 is closer to UE1). Similarly, as shown in 500B, when it is determined that UE1 is located in front of UE2, the distance d between the two user devices can be measured and estimated by UE1 by receiving a reference signal sent from AP3 of UE2 through AP1 (because AP3 is closer to UE1). It should be noted that in the latter case, since UE1 knows that AP1 is located in front of itself, it can make appropriate adjustments when calculating the distance d, such as subtracting its own device length (eg, vehicle length).

[0067] It should be understood that the positions of the antenna panels in Figure 5 are merely examples and are not intended to be limiting. For example, in practice, the first antenna panel may also be located in the middle of the first user device, and then half of the length of its own device may be subtracted when measuring and estimating the distance d between the first user device and the second user device. In some special scenarios, the first user device and the second user device may even each use only one antenna panel to measure the distance between the two user devices. For example, if the first user device has determined that the antenna panel of the second user device is located in its middle position based on the time-frequency resources of the received reference signal, and the antenna panel of the first user device also happens to be located in its middle position, then the two user devices may use only these two antenna panels to transmit reference signals for distance measurement and estimation.

[0068] It should also be understood that the method in the first example above can also be applied to determining the positional relationship and spacing of multiple user devices in other directions. For example, the relative left-right positional relationship and left-right spacing of multiple user devices can be determined, where the first antenna panel can be located on the left or right side of the first user device, and the third and fourth antenna panels can be located on the left and right sides of the second user device.

[0069] Furthermore, in a scenario where a first user equipment (UE1) and a second user equipment (UE2) move in the same straight line, based on the determined relative positions of UE1 and UE2, UE1 can determine whether there is any abnormality in the movement between UE1 and UE2 through the first distance measured by AP1 between UE1 and AP3 of UE2 and the second distance measured between UE1 and AP4 of UE2.

[0070] Specifically, as shown in 500A, if UE1 is determined to be behind UE2, based on the first distance being less than the second distance, it can be determined that there is an abnormality in the movement between UE1 and UE2. For example, in the example where UE1 and UE2 are both vehicles, according to traffic rules that two vehicles in the same lane should travel in the same direction, the first distance should be greater than the second distance. When the opposite distance occurs, while UE1 ensures that it is driving normally, it can be determined that UE2's driving state is abnormal. For example, UE2 is likely traveling in the opposite direction of UE1. In this scenario, UE1 can take timely remedial measures, including but not limited to changing its own lane, sending a warning to UE2 to change its driving direction, sending a warning to vehicles behind UE1 to avoid UE2, etc. Similarly, as shown in 500B, if UE1 is determined to be in front of UE2, based on the first distance being greater than the second distance, it can be determined that there is an abnormality in the movement between UE1 and UE2. While UE1 ensures that it is driving normally, it can be determined that UE2's driving state is abnormal. For example, UE2 is likely traveling in the opposite direction of UE1. In this scenario, UE1 can take timely remedial measures, including but not limited to changing its own driving lane, sending warnings to UE2 to change its driving direction, sending warnings to other vehicles behind UE1 to avoid UE2, etc.

[0071] In summary, in the first example, a first user device can utilize a single antenna panel to receive reference signals transmitted by multiple antenna panels of a second user device, and determine the positions of the multiple antenna panels of the second user device based on the time resources and / or frequency resources occupied by the reference signals. Based on this, the first user device can implement various positioning functions, including determining its relative position with respect to the second user device, determining the distance between it and the second user device, and determining whether there are any anomalies in the movement between it and the second user device.

[0072] Second example of positioning in sidelink communication

[0073] In the second example of sidelink positioning, the second user device, primarily serving as a transmitter, can have multiple antenna panels, and the first user device, primarily serving as a receiver, can have and utilize multiple antenna panels, thereby implementing a series of positioning-related operations. Figure 6 shows a schematic diagram of a second example of positioning in sidelink communications according to an embodiment of the present disclosure.

[0074] In Figure 6, the first user equipment is shown as UE1, on which at least a first antenna panel (shown as AP1) and a second antenna panel (shown as AP2) are installed; the second user equipment is shown as UE2, on which at least a third antenna panel (AP3) and a fourth antenna panel (AP4) are installed. By way of example only and not limitation, AP1 in the figure is located in front of UE1, and AP2 is located behind UE1; AP3 is located in front of UE2, and AP4 is located behind UE2. It can be seen that the second example, based on the first example, enables the first user equipment to also utilize multiple antenna panels installed in multiple locations thereon to implement positioning functions in sidelink communications.

[0075] Similar to the first example, in the second example, the time resources and / or frequency resources occupied by the reference signal sent by AP3 are associated with the position of AP3 on UE2 (e.g., the front), and the time resources and / or frequency resources occupied by the reference signal sent by AP4 are associated with the position of AP4 on UE2 (e.g., the rear). It should be appreciated that the association between the position of AP3 on UE2 and one or more time resources and / or frequency resources, and the association between the position of AP4 on UE2 and one or more time resources and / or frequency resources, can be determined by default or can be notified to UE1 in advance by UE2. Generally speaking, the one or more time resources and / or frequency resources associated with AP3 and the one or more time resources and / or frequency resources associated with AP4 are independent of each other and do not overlap. Accordingly, UE1 can receive the reference signal sent by AP3 (or AP4) of UE2 through AP1 (or AP2), and can determine the position of AP3 (or AP4) on UE2 based on the association between the antenna panel position and the time-frequency resources and the time-frequency resources occupied by the reference signal.

[0076] According to a second example of an embodiment of the present disclosure, the relative positions of the first user equipment (UE1) and the second user equipment (UE2) may be determined, for example, the relative position relationship may be determined.

[0077] The two methods for determining the relative position between UE1 and UE2 have been described in the first example, wherein UE1 can use any antenna panel of AP1 or AP2 to perform the operation, which will not be repeated here.

[0078] According to a second example, another method for determining the relative position between UE1 and UE2 may include UE1 receiving, via AP1, a first reference signal transmitted by an antenna panel in AP3 or AP4 of UE2, and UE1 receiving, via AP2, a second reference signal transmitted by the same antenna panel in AP3 or AP4 of UE2. Based on the reception strengths of the first reference signal and the second reference signal, the front-to-back positional relationship between UE1 and UE2 may be determined.

[0079] Specifically, as shown in 600A, UE1 can receive a first reference signal sent by AP4 of UE2 through AP1, and UE1 can receive a second reference signal sent by AP4 of UE2 through AP2 (alternatively, the first reference signal and the second reference signal can be sent by AP3 of UE2). When the strength of the first reference signal is greater than the strength of the second reference signal, since UE1 knows the installation positions of AP1 and AP2 on itself, it can be determined that UE1 is located behind UE2. Similarly, as shown in 600B, UE1 can receive a first reference signal sent by AP3 of UE2 through AP1, and UE1 can receive a second reference signal sent by AP3 of UE2 through AP2 (alternatively, the first reference signal and the second reference signal can be sent by AP4 of UE2). When the strength of the first reference signal is less than the strength of the second reference signal, UE1 can determine that it is located in front of UE2.

[0080] It should be understood that the strength of the reference signal referred to in this article may include but is not limited to one or a combination of multiple of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), reference signal signal to interference and noise ratio (SINR), etc.

[0081] Furthermore, based on the determined relative positions of UE1 and UE2, UE1 can receive a reference signal sent by an antenna panel in AP3 or AP4 of UE2 through an antenna panel in AP1 or AP2, so as to measure the distance between UE1 and UE2. As an example, when UE1 and UE2 are both vehicles traveling normally, the distance (vehicle distance) d between them generally refers to the distance between the front of the rear vehicle and the rear of the front vehicle. Thus, the reference signals transmitted by the two closest antenna panels on UE1 and UE2 can be selected to measure or estimate the distance. Specifically, as shown in 600A, when it is determined that UE1 is located behind UE2, the distance d between the two user devices can be measured and estimated by UE1 by receiving a reference signal sent from AP4 of UE2 through AP1. This is because UE1 knows that AP1 is located in front of it, and based on receiving the reference signal sent by AP4, it knows that it is located behind UE2, and the two antenna panels are closest. Similarly, as shown in 600B, when it is determined that UE1 is located in front of UE2, the distance d between the two user equipments can be measured and estimated by UE1 receiving a reference signal transmitted from AP3 of UE2 via AP2. It should be noted that, compared with the first example, the method for measuring the distance between user equipments in the second example generally does not require additional adjustment.

[0082] It should be understood that the positions of the antenna panels in Figure 6 are merely examples and are not intended to be limiting. For example, the method in the second example above can also be applied to determining the relative left-right position relationship and left-right spacing of multiple user devices, where the first antenna panel and the second antenna panel can be located on the left and right sides of the first user device, and the third antenna panel and the fourth antenna panel can be located on the left and right sides of the second user device.

[0083] It should also be understood that the second example primarily illustrates the positioning functionality that can be achieved by the first user device using multiple antenna panels installed at multiple locations thereon. If the first user device only uses one of the multiple antenna panels, the method described in the first example can be used to achieve various positioning operations.

[0084] It should be appreciated by those skilled in the art that, in the case where the first user equipment and the second user equipment each have multiple antenna panels, the functions of the two can be interchanged. In other words, the first user equipment can also be mainly used as a transmitting user equipment, and the second user equipment can also be mainly used as a receiving device. For example, the time resources and / or frequency resources occupied by the reference signal sent by AP1 are associated with the position of AP1 on UE1 (for example, the front), and the time resources and / or frequency resources occupied by the reference signal sent by AP2 are associated with the position of AP2 on UE1 (for example, the back). This association relationship can be determined by default or can be notified to UE2 in advance by UE1. Based on this, UE2 can use the method performed by UE1 in the above example to implement a series of operations related to positioning.

[0085] Distance measurement and estimation methods

[0086] In the first and second examples of positioning in wireless sidelink communication, both involve using the antenna panel of the second user equipment and the antenna panel of the first user equipment to measure and estimate the distance between the two. Two feasible methods for measuring and estimating the distance are introduced below.

[0087] According to some embodiments of the present disclosure, the reference signal received power (RSRP) can be used to measure and estimate distance. Specifically, the distance between the antenna panel i of the transmitting user equipment and the antenna panel j of the receiving user equipment can be calculated by the power path loss of the reference signal sent from antenna panel i to antenna panel j. As an example, the two have the following relationship: PL i,j =32.4+20lgD i,j +20lgf

[0088] In the above formula, PL i,j represents the path loss of the reference signal transmitted between antenna panels i and j, D i,j represents the distance between antenna panel i of the transmitting user equipment and antenna panel j of the receiving user equipment, and f represents the frequency (unit: MHz). Therefore, using the above relationship, the distance between the two antenna panels of the two user equipments can be calculated using the received power loss of the reference signal. Furthermore, the distance between the two user equipments can be calculated through appropriate adjustments. Similarly, the distance between user equipments can be measured and estimated using methods such as reference signal received quality (RSRQ).

[0089] According to other embodiments of the present disclosure, the round trip time (RTT) of the reference signal can be used to measure and estimate the distance. Specifically, the first user equipment can send a first positioning reference signal to the second user equipment, and the second user equipment can send a second positioning reference signal to the first user equipment. The first user equipment will receive the second positioning reference signal and send the first positioning reference signal. The second user equipment will receive the first positioning reference signal and send the second positioning reference signal between the time difference The first user device then adds ΔT1 in the first positioning information and ΔT2 in the second positioning information to obtain the round trip time RTT = ΔT1 + ΔT2. Based on the electromagnetic signal propagation formula, the distance between the two user devices can be calculated as d = c·RTT / 2, where c can be the speed of light (3×10 8 m / s. It should be noted that in the above process, the first user device uses the same antenna panel to send the first positioning reference signal and receive the second positioning reference signal. Similarly, the second user device uses the same antenna panel to send the second positioning reference signal and receive the first positioning reference signal. In other words, the above distance is the distance between the antenna panels on the two devices. The distance can then be appropriately adjusted based on the position of the antenna panels to obtain the distance between the two devices. It should be understood that in the RTT ranging method, the same user device serves as both a receiving device and a transmitting device.

[0090] Information interaction

[0091] The schematic configuration and operation flow of a first user equipment (primarily used as a receiving user equipment) and a second user equipment (primarily used as a transmitting user equipment) according to an embodiment of the present disclosure have been described above with reference to the accompanying drawings. Now, with reference to FIG7 , a communication interaction diagram for positioning in sidelink communication in a wireless communication system according to an embodiment of the present disclosure will be described.

[0092] As shown in Figure 7, at 701, the second user equipment notifies the first user equipment in advance of the association relationship between the location of one or more antenna panels on the second user equipment and one or more time resources / frequency resources (also referred to as time-frequency resources in this document). This disclosure pays special attention to the scenario where the user equipment has multiple antenna panels, so the following interaction process is described using the example of the first user equipment and the second user equipment each having an antenna panel located at two different locations. As mentioned above, the time-frequency resources associated with the two different antenna panels on the user equipment can be independent of each other and non-overlapping. Alternatively, the above-mentioned association relationship can be determined by default, or can be predetermined by the network device and then notified to each user equipment. Based on the above-mentioned association relationship, the first user equipment can determine the location of the antenna panel that sent the reference signal on the second user equipment based on the time-frequency resources occupied by the received reference signal, thereby performing a series of operations related to positioning to improve positioning performance. Additionally and optionally, the second user equipment can also send a message to the first user equipment in advance indicating that it has multiple antenna panels, so that the first user equipment can flexibly configure the reception of reference signals sent by multiple antenna panels for positioning-related operations.

[0093] At 702, the first user device may receive a reference signal from the second user device for determining the relative position of the first user device and the second user device (e.g., front-to-back position relationship, left-to-right position relationship, up-down position relationship, etc.) (703). According to some embodiments of the present disclosure, the first user device may receive reference signals sent from two antenna panels of the second user device through an antenna panel installed thereon, and determine the relative position of the first user device and the second user device based on the strength of these reference signals and the position of the corresponding antenna panel that sends the reference signals (e.g., refer to the first example in the present disclosure and the operation described in FIG5). According to other embodiments of the present disclosure, the first user device may receive reference signals sent from the same antenna panel of the second user device through two antenna panels installed thereon, and determine the relative position of the first user device and the second user device based on the position of its own antenna panel and the strength of the corresponding reference signal received (e.g., refer to the second example in the present disclosure and the operation described in FIG6). Optionally, the satellite navigation positioning system GPS may also be used to roughly determine the position relationship between the first user device and the second user device.

[0094] At 704, the first user device receives a reference signal from the second user device for measuring and estimating the distance between the first user device and the second user device (705). It should be understood that the distance between the two user devices herein refers to the distance between the closest parts of the two user devices. For example, in an example where the first user device and the second user device are both vehicles, the distance between the two can be the distance between the front of the rear vehicle and the rear of the front vehicle, or the distance between the right side of the left vehicle and the left side of the right vehicle. According to some embodiments of the present disclosure, the first user device can receive a reference signal sent from one of the two antenna panels of the second user device that is closest to the first user device through an antenna panel installed thereon (the closest antenna panel can be determined based on the determined relative positions of the two user devices) to determine the distance between the first user device and the second user device. It should be understood that in this case, it may be necessary to make appropriate adjustments to the estimated distance as needed to remove the influence of the position of the antenna panel on the first user device on the distance estimation (for example, with reference to the first example and the operation described in FIG5 in the present disclosure). According to some other embodiments of the present disclosure, a first user device can receive a reference signal sent from one of the two antenna panels of a second user device that is closest to the first user device through one of the two antenna panels installed thereon that is closest to the second user device (the closest antenna panel can be determined based on the determined relative positions of the two user devices) for determining the distance between the first user device and the second user device (for example, refer to the second example in the present disclosure and the operations described in Figure 6).

[0095] Those skilled in the art will appreciate that the above-mentioned distance measurement and estimation can be performed using methods such as Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ). Alternatively, the distance measurement and estimation can also be performed using the Reference Signal Round Trip Time (RTT) method. In the RTT method, in addition to receiving a positioning reference signal from the second user equipment, the first user equipment also needs to send a positioning reference signal to the second user equipment.

[0096] At 706, the first user device receives a reference signal from the second user device to determine whether there is an abnormality in the position or movement between the first user device and the second user device (707). This operation is mainly aimed at the scenario where the first user device and the second user device move on the same straight line. As an example, the first user device measures the distance between the same antenna panel of its own and the two antenna panels of the second user device (for example, including the first distance and the second distance). Based on the determined relative position of the first user device and the second user device, the first user device compares the size of the first distance and the second distance. If the size relationship does not match the size relationship under normal movement, then the first user device can determine that there is an abnormality in the movement between the first user device and the second user device. For example, while ensuring that its own movement is normal, the first user device can determine that there is an abnormality in the movement of the second user device.

[0097] Accordingly, at step 708, the first user device may notify the second user device of the previously determined relative position to the second user device, the distance between the first user device and the second user device, and any abnormal movement with respect to the second user device. For example, if abnormal movement occurs, the first user device may change its own movement trajectory and warn the second user device so that the second user device can return to normal operation as soon as possible.

[0098] It should be noted that the interaction diagram in FIG7 is merely an example and is not intended to be limiting. The diagram may include more or fewer steps, and the steps may be performed in a different order than depicted in the diagram. As an example, 708 may be divided into three steps, wherein the first user device notifies the second user device of information regarding the relative position, distance estimate, and movement anomaly, respectively. Alternatively, the three steps may be performed immediately after 703, 705, and 707, respectively.

[0099] It should be understood that, symmetrically, the interaction in Figure 7 is also applicable in a scenario where the second user device is mainly used as a receiving end and the first user device is mainly used as a sending end. In other words, in this scenario, operations similar to the operations at 701, 702, 704 and 706 (for example, assuming they are recorded as 701', 702', 704' and 706') can be sent by the second user device to the first user device, and operations similar to the operations at 703, 705 and 707 (for example, assuming they are recorded as 703', 705' and 707') can be performed by the second user device. It should also be understood that the operations of 701'-707' can be performed after the operations of 701-707, or can be performed in a time-interlaced manner with the operations of 701-707, and in this case step 708 can be omitted.

[0100] For sidelink communications in wireless communication systems, the present disclosure proposes a method for associating the position of an antenna panel on a user device with one or more time resources and / or frequency resources, so that the receiving user device can determine the position of the antenna panel that transmits the reference signal on the transmitting user device based on the time resources and / or frequency resources occupied by the reference signal. Furthermore, based on this concept, the present disclosure proposes a method for operations related to positioning in sidelink communications, including determining the relative positions of multiple user devices, determining the distance between multiple user devices, and determining whether there are any abnormalities in the movement between multiple user devices.

[0101] According to the inventive concept and technical solution proposed in the present disclosure, beneficial technical effects can be achieved. On the one hand, the present disclosure can select the reference signal transmitted by the antenna panel that is closer to the two user devices to measure and estimate the distance, thereby improving the estimation accuracy of the distance between the two user devices. On the other hand, the present disclosure can conveniently determine whether there is abnormal device movement based on the determined relative positions of the two user devices and by comparing the measured distances to the antenna panels at different positions on the transmitting end device. This can effectively improve safety performance in scenarios such as vehicle-mounted user device communications, for example, allowing vehicles to change driving tracks in time and issue warnings to abnormal vehicles. On the other hand, the time resources and / or frequency resources occupied by the reference signal are used to implicitly indicate the installation position (or attachment position) of the antenna panel that sends the reference signal on the user device, which can greatly save message overhead. On the other hand, the user device can know whether the other user device is a user device with multiple antenna panels based on the received association relationship, so that the received reference signal can be flexibly used to perform positioning operations.

[0102] Exemplary Methods

[0103] FIG8 shows a flowchart of an example method 800 for a first user equipment in a wireless communication system according to an embodiment of the present disclosure. The method can be performed by a first user equipment (e.g., a user equipment primarily used as a receiver) (or more specifically, the electronic device 200) in sidelink communication. As shown in FIG8 , the method 800 may include receiving, via a first antenna panel mounted on the first user equipment, a reference signal transmitted by a third antenna panel mounted on a second user equipment (e.g., a user equipment primarily used as a transmitter), wherein the time resources and / or frequency resources occupied by the reference signal are associated with the location of the third antenna panel on the second user equipment (block S801). At block S802, the first user equipment may determine the location of the third antenna panel on the second user equipment based on the association between the location of the third antenna panel on the second user equipment and one or more time resources and / or frequency resources and the time resources and / or frequency resources occupied by the reference signal. Detailed example operations of the method can be referred to above regarding the description of the operation of the first user equipment (or more specifically, the electronic device 200), which will not be repeated here.

The method can be performed by a second user equipment (e.g., a user equipment primarily used as a transmitter) (or more specifically, an electronic device 500) in sidelink communication. As shown in Figure 9, the method 900 may include using a third antenna panel installed on the second device user to send a reference signal to a first user equipment (e.g., a user equipment primarily used as a receiver), where the time resources and / or frequency resources occupied by the reference signal are associated with the position of the third antenna panel on the second user equipment, so that the first user equipment determines the position of the third antenna panel on the second user equipment based on the association relationship between the position of the third antenna panel on the second user equipment and one or more time resources and / or frequency resources and the time resources and / or frequency resources occupied by the reference signal, as shown in block S901. The detailed example operations of the method can be referred to the above description of the operation of the second user equipment (or more specifically, the electronic device 300), which will not be repeated here.
