Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

The method for sending an auxiliary resource set provided by the embodiment of the present disclosure can be applied to the direct-connected communication system shown in FIG. 1 . Referring to FIG. 1 , in the scenario of direct communication between directly connected communication devices, the network device configures various transmission parameters for data transmission for the directly connected communication device 1 . The direct-connected communication device 1, the directly-connected communication device 2 and the directly-connected communication device 3 perform direct-connected communication. Obstacles may exist between the directly connected communication device 2 and the directly connected communication device 3 . The link for communication between the network device and the directly connected communication device is an uplink and downlink, and the link between the directly connected communication device and the directly connected communication device is a sidelink.

In the present disclosure, the communication scenario of the direct communication between the directly connected communication devices may be a vehicle wireless communication technology (Vehicle to Everything, V2X) business scenario. Among them, V represents the in-vehicle device and X represents any object that interacts with the in-vehicle device. Currently X mainly includes in-vehicle devices, handheld devices, traffic roadside infrastructure and networks. The information modes of V2X interaction include: Vehicle to Vehicle (V2V), Vehicle to Infrastructure (V2I), Vehicle to Pedestrian (Vehicle to Pedestrian, V2I) V2P), the interaction between in-vehicle devices and the network (Vehicle to Network, V2N).

With the development of the new generation of 5G mobile communication technology, the use of 5G NR technology in 3GPP Rel-16 has realized support for new V2x communication services and scenarios, such as fleet management (Vehicles Platooning), extended perception (Extended Sensors), advanced Driving (Advanced Driving), and remote driving (remote driving), etc. In general, 5G V2x sidelink can provide higher communication rate, shorter communication delay, and more reliable communication quality.

The communication scenario of direct communication between directly connected communication devices may also be a device to device (Device to Device, D2D) communication scenario. The direct-connected communication devices that perform direct communication in the embodiments of the present disclosure may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to wireless modems, as well as various forms of users Equipment (User Equipment, UE), mobile station (Mobile station, MS), terminal (terminal), terminal equipment (Terminal Equipment) and so on. For convenience of description, the embodiments of the present disclosure are described below by taking the direct-connected communication device as the user equipment as an example.

Among them, the enhancement of NR Sidelink can improve transmission reliability and reduce delay. In the enhancement of NR Sidelink, in the aspect of enhancing Mode2 resource allocation, the 3GPP working group reached a conclusion that it is necessary to study a way to assist the selection of resources between user equipments. In this manner, two user equipments are specified. For example, user equipment A is an auxiliary user equipment of user equipment B, and user equipment B refers to the user equipment that needs to perform resource selection for the data sent by itself. Among them, user equipment A will determine a resource set and send it to user equipment B in mode 2. When user equipment B selects resources, it will consider the resource set sent by user equipment A, that is, it can be understood as user equipment B Use an auxiliary resource set to assist in resource selection. Wherein, user equipment B may send data to user equipment A and/or other user equipments.

However, in the communication method for resource selection based on the auxiliary resource set assistance mechanism in the related art, the transmission method of the auxiliary resource set has not been studied, that is, when user equipment A sends the auxiliary resource set to user equipment B, it needs to be studied. of.

An embodiment of the present disclosure provides a method for sending an auxiliary resource set. In the method for sending an auxiliary resource set, a condition for triggering the sending of the auxiliary resource set is predefined, and when the predefined condition is satisfied, the sending of the auxiliary resource set is triggered. For example, the above-mentioned user equipment A triggers to send the auxiliary resource set to the user equipment B when it is determined that a predefined condition is met.

In an implementation manner, in this embodiment of the present disclosure, the pre-defined conditions include conditions set based on the distance between user equipments that use the auxiliary resource set assistance mechanism for communication, and based on the distance between the user equipments, triggering the auxiliary resource set send.

For convenience of description in the embodiments of the present disclosure, the user equipment that sends the auxiliary resource set is referred to as the first user equipment, and the user equipment that receives the auxiliary resource set and uses the auxiliary resource set to assist in resource selection is referred to as the second user equipment.

Fig. 2 is a flowchart showing a method for sending an auxiliary resource set according to an exemplary embodiment. As shown in Fig. 2 , the method for sending an auxiliary resource set is used in a first user equipment, and includes the following steps.

In step S11, at least one parameter related to the distance between the first user equipment and the second user equipment is determined.

In step S12, based on the distance between the first user equipment and the second user equipment, the auxiliary resource set is sent to the second user equipment.

In this embodiment of the present disclosure, sending the auxiliary resource set to the second user equipment based on at least one parameter related to the distance between the first user equipment and the second user equipment can be implemented between the first user equipment and the second user equipment When the distance satisfies the preset condition, the first user equipment is triggered to send the auxiliary resource set to the second user equipment.

In some embodiments, the at least one parameter related to the distance may exemplarily be: a distance value between the first user equipment and the second user equipment. In still other embodiments, it can also be exemplified as: an identifier or a field field for the distance value between the first user equipment and the second user equipment. In still other embodiments, it can also be exemplified as: an identifier or a field field used to identify the distance interval between the first user equipment and the second user equipment, for example, the distance can be divided into a plurality of distance intervals ( For example: the first distance interval is 0-100 meters, the second distance interval is 101-200 meters...), and then corresponding to one or more distance intervals, the corresponding identifier or character field is determined. In still other embodiments, one or more parameters for calculating the distance between the first user equipment and the second user equipment may be exemplified; The formula and the first parameter determine the distance between the first user equipment and the second user equipment; another example: determine two or more parameters, and determine the distance between the first user equipment and the second user equipment according to the preset formula and these parameters The distance between the second user equipments.

In the embodiments of the present disclosure, firstly, an implementation process in which the first user equipment determines the distance between the first user equipment and the second user equipment is described.

In an implementation manner, the embodiment of the present disclosure determines the distance between the first user equipment and the second user equipment based on the zone ID (zone ID) included in the second-stage sidelink control information (Sidelink Control Information, SCI). .

In one embodiment, in response to the first user equipment sending the auxiliary resource set in a unicast and/or broadcast manner, the zone ID is borne in the SCI 2-A. And/or in response to the first user equipment sending the auxiliary resource set in a multicast manner, the zone ID is borne in the SCI 2-B. In other words, for the measurement of the distance between the first user equipment and the second user equipment in the multicast scenario, through the information field in the second stage SCI 2-B, the zone ID with a length of 12 bits is used to estimate the distance between the first user equipment and the second user equipment. The distance between two user equipments. For other unicast and broadcast scenarios, it can be considered to add the information field of zone ID to SCI 2-A to estimate the distance between the first user equipment and the second user equipment.

Wherein, in the embodiment of the present disclosure, when estimating the distance between the first user equipment and the second user equipment based on the zone ID in the second stage SCI, the following formula can be used:

x1=Floor(x/L)Mod 64 Formula 1

y1=Floor(y/L)Mod 64 Formula 2

Zone_id=y1*64+x1 Formula 3

Among them, L is the value of the sl-Zone length included in the sl-Zone configuration. x is the geodesic longitude distance between the current location of the user equipment and the geographic coordinates (0, 0) according to the WGS84 model, and the unit is meters. y is the geodesic latitude distance between the current location of the user equipment and the geographic coordinates (0, 0) according to the WGS84 model, and the unit is meters.

Among them, the zone area is square, and each zone has a zone ID. The design of the zone in the R16 protocol is based on HARQ feedback within a certain distance. In the multicast service, when the distance between two UEs exceeds a certain distance, no HARQ feedback is performed for this data transmission. If this distance is not exceeded, HARQ feedback is required for this data transmission.

In an example, the first user equipment receives the SCI of the second user equipment, and the SCI 2-B of the second user equipment carries the information field of the zone ID. After the first user equipment knows the zone ID of the second user equipment, according to formula 3, the values of x1 and y1 of the second user equipment can be calculated. The first user equipment knows its own information of xA and yA, and directly calculates the distance X between the first user equipment and the second user equipment through a distance formula between two points. At the same time, because the value of the zone ID is repeated cyclically, there will be cases where multiple zones have the same zone ID. FIG. 3 shows a schematic diagram of determining a zone ID in an exemplary embodiment of the present disclosure. Wherein, referring to Figure 3, after the first user equipment receives the zone ID of the second user equipment, there will be 9 zones with the same zone ID, but the first user equipment will find a distance from the second user equipment. The nearest zone is used as the zone for calculating the distance between the two. As shown in Figure 3, the zones with serial numbers 0-8 have the same zone ID. If the zone with serial number 4 is the closest to the first user equipment, then the zone with serial number 4 will be used to calculate the first user. The distance between the device and the second user device.

The following embodiments of the present disclosure describe a process in which the first user equipment triggers the provision of an auxiliary resource set to the second user equipment based on the distance.

In an implementation manner of the embodiment of the present disclosure, when the distance between the first user equipment and the second user equipment satisfies a preset condition, the first user equipment sends an auxiliary resource set to the second user equipment. In another implementation manner, when the distance between the first user equipment and the second user equipment does not meet the preset condition, the first user equipment does not send the auxiliary resource set to the second user equipment.

In an implementation manner of the embodiment of the present disclosure, the foregoing preset condition for triggering the first user equipment to send the auxiliary resource set to the second user equipment may be determined based on the resource set to be selected by the second user equipment.

Among them, in the mode2 resource allocation, the user equipment senses resources in the resource pool, and the perceived resource interference has a certain degree of correlation with the distance between the user equipments. Because the distances between the first user equipment and the second user equipment are different, the interference situations of the reserved resources perceived by the two are different, and the determined candidate resource sets are also different. Wherein, the closer the distance between the first user equipment and the second user equipment, the more similar the resource sets perceived by the two. The longer the distance between the first user equipment and the second user equipment, the greater the difference in resource sets perceived by the two.

Wherein, the second user equipment has the following two resource set requirements based on the communication scenario that does not pass. In a resource requirement, the first user equipment is required to provide an auxiliary resource set similar to the resource set perceived by the second user equipment. In another resource requirement, the second user equipment is required to provide an auxiliary resource set that is quite different from the resource set perceived by the second user equipment.

In this embodiment of the present disclosure, in order to provide an auxiliary resource set that is significantly different from the second user equipment perception resource set, a first distance threshold may be set, and the preset condition is set to be between the first user equipment and the second user equipment. The distance is greater than or equal to the first distance threshold. Wherein, in response to the distance between the first user equipment and the second user equipment being greater than or equal to the first distance threshold, the first device sends the auxiliary resource set to the second user equipment.

In this embodiment of the present disclosure, the first distance threshold may be a preset distance value. The first distance threshold may be configured by radio resource control (Radio Resource Control, RRC) signaling.

In this embodiment of the present disclosure, in order to provide an auxiliary resource set similar to the second user equipment perception resource set, a second distance threshold may be set, and the preset condition is set to be less than or equal to the distance between the first user equipment and the second user equipment The second distance threshold. In response to the distance between the first user equipment and the second user equipment being less than or equal to the second distance threshold, the auxiliary resource set is sent to the second user equipment.

In this embodiment of the present disclosure, the second distance threshold may be a preset distance value. Wherein, the second distance threshold may be configured by RRC signaling.

In the embodiment of the present disclosure, the first distance threshold and the second distance threshold may be the same distance value, or may be different distance values, which are not limited in the embodiment of the present disclosure.

Further, in this embodiment of the present disclosure, a preset condition for triggering the first user equipment to send the auxiliary resource set to the second user equipment may be selected based on whether the first user equipment is a receiving end device of data transmitted by the second user equipment.

In an embodiment, the first user equipment is a receiving end device of data transmitted by the second user equipment, and the preset condition is set as the distance between the first user equipment and the second user equipment is greater than or equal to a first distance threshold. In response to the distance between the first user equipment and the second user equipment being greater than or equal to the first distance threshold, the auxiliary resource set is sent to the second user equipment.

In an example, the distance between the first user equipment and the second user equipment is relatively far (greater than the first distance threshold), but the first user equipment is far away from the receiver of the data transmitted by the second user equipment, such as The third user equipment is relatively close. Because the distance between the first user equipment and the third user equipment is very close, the resource set perceived by the first user equipment is basically the same as the resource set perceived by the third user equipment. At this time, the first user equipment and the second user equipment The difference between the perceived resource sets is relatively large, so the first user equipment sends the auxiliary resource set to the second user equipment, as shown in FIG. 4 , for example. FIG. 4 shows a schematic diagram of sending an auxiliary resource set by a first user equipment to a second user equipment according to an exemplary embodiment of the present disclosure. Referring to FIG. 4 , the first user equipment is relatively close to the third user equipment, and the distance between the first user equipment and the second user equipment is greater than or equal to the first distance threshold, and the first user equipment sends a message to the second user equipment. Auxiliary resource set. 5 shows a schematic diagram of sending an auxiliary resource set by a first user equipment to a second user equipment according to an exemplary embodiment of the present disclosure. In the extreme situation shown in FIG. 5 , it can be understood that the first user equipment is the third user equipment, that is, the first user equipment is the receiving end device of the second user equipment, as shown in FIG. 5 . In this case, if the distance between the first user equipment and the second user equipment is too far, the difference between the resource sets perceived by the two is very large, and the resource sets perceived by the first user equipment and the second user equipment are greatly different, When the first user equipment sends the resource set to the second user equipment, the second user equipment can comprehensively consider the resource set it perceives and the resource set provided by the first user equipment, so as to select appropriate resources and improve the reliability of data transmission sexual. If the distance between the first user equipment and the second user equipment is very close, the resource sets perceived by the first user equipment and the second user equipment are basically similar, and the first user equipment does not need to provide assistance to the second user equipment at this time. resource set. Therefore, in this scenario, if the distance between the first user equipment and the second user equipment is greater than or equal to the first distance threshold, the first user equipment should provide the second user equipment with the auxiliary resource set. At this time, the auxiliary resource set provided by the first user equipment is most helpful to the second user equipment.

In another implementation manner, in the embodiment of the present disclosure, the first user equipment is a non-receiving end device of data transmitted by the second user equipment. The preset condition is set as the distance between the first user equipment and the second user equipment is less than or equal to the second distance threshold. The auxiliary resource set is sent to the second user equipment in response to the distance between the first user equipment and the second user equipment being less than or equal to the second distance threshold.

In an example, the first user equipment is not a receiver device of the second user equipment, and the third device is a receiver device of the second user equipment. It is assumed that the third user equipment is relatively close to the second user equipment (less than or equal to the second distance threshold), or the third user equipment is relatively far away from the second user equipment. FIG. 6 is a schematic diagram illustrating that the third user equipment is far away from the second user equipment, but the third user equipment is still within the communication range of the second user equipment to send the auxiliary resource set. FIG. 7 is a schematic diagram illustrating that the third user equipment is relatively close to the second user equipment and the auxiliary resource set is sent. It is assumed that regardless of whether the second user equipment is far or near to the third user equipment, when the first user equipment and the second user equipment are relatively close, the resource sets that can be perceived by the first user equipment and the second user equipment are basically similar. Due to the half-duplex problem, the second user equipment cannot receive data while sending data, so it cannot sense certain time slots (slots), but the first user equipment can sense this slot at this time, so the first user equipment The second user equipment can be informed of the resource situation of the slot that the second user equipment cannot perceive by providing an auxiliary resource set to the second user equipment, but the first user equipment needs to be very close to the second user equipment for the first user equipment to be accurate. The resource usage situation on the slot near the second user equipment is well perceived. Therefore, the distance between the first user equipment and the second user equipment is less than or equal to the second distance threshold, and the first user equipment provides the auxiliary resource set to the second user equipment.

The method for sending an auxiliary resource set provided by this embodiment of the present disclosure predefines two conditions:

The first type: the distance X between the first user equipment and the second user equipment>the preset value, or the distance X between the first user equipment and the second user equipment=the preset value, at this time, the first user equipment to the second user equipment Send the resource set.

The second type: the distance X between the first user equipment and the second user equipment < the preset value, or the distance X between the first user equipment and the second user equipment = the preset value, at this time the first user equipment to the second user equipment Send the resource set.

Further, when determining the distance between the first user equipment and the second user equipment, in the multicast scenario, the distance between UEs is measured, through the information field in the second stage SCI 2-B, a zone with a length of 12 bits. ID to estimate the distance between UEs. In other unicast and broadcast scenarios, the information field of zone ID can be added to SCI 2-A to estimate the distance between UEs.

Based on the same concept, an embodiment of the present disclosure also provides an apparatus for sending an auxiliary resource set.

It can be understood that, in order to implement the above-mentioned functions, the auxiliary resource set apparatus provided by the embodiments of the present disclosure includes corresponding hardware structures and/or software modules for executing each function. Combining with the units and algorithm steps of each example disclosed in the embodiments of the present disclosure, the embodiments of the present disclosure can be implemented in hardware or a combination of hardware and computer software. Whether a function is performed by hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solutions of the embodiments of the present disclosure.
