Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method, device, apparatus, and storage medium for determining transmission resources. Background Art

[0002] Currently, in order to support direct communication between terminals, a sidelink (SL) communication method has been introduced. In SL communication, resource sensing needs to be performed first to allocate transmission resources to terminals performing SL communication.

[0003] In related technologies, resource scheduling can be performed uniformly by the network side, or SL terminals can rely on random selection or resource listening to select transmission resources from a network-configured or pre-configured resource pool for SL resource sensing.

[0004] However, with the introduction of Frequency Range 2 (FR2), fixed-line antennas will become the standard configuration of SL terminals. In related technologies, whether it is unified scheduling by the network side or autonomous selection by terminals, SL resource sensing is based on the full-coverage characteristics of the omnidirectional antennas of SL terminals, and resource sensing of directional antennas cannot be achieved.

[0160] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0161] In the embodiments of this application, the term "plurality" refers to two or more, and other quantifiers are similar.

[0162] First, the resource awareness of SL in the related art will be described below.

[0163] In the related art, the resource awareness of SL can be performed through two modes, including mode 1 and mode 2. Figure 1 Schematic diagram of a scenario for transmission based on network scheduling in the related art, Figure 2 Schematic diagram of resource selection in mode 1 in the related art, as Figure 1 and Figure 2 shown. In the scenario of mode 1, the terminal does not need to perform resource awareness by itself, but the network side uniformly performs resource scheduling, including dynamic scheduling resource allocation and semi-static scheduling resource allocation.

[0164] Among them, for dynamic scheduling resource allocation, the network device allocates SL transmission resources for the terminal through Downlink Control Information (DCI). One DCI can only allocate transmission resources for one SL data. For semi-static scheduling resource allocation, the network device semi-statically allocates a group of SL resources for the terminal through Radio Resource Control (RRC) signaling and DCI signaling, and then the terminal uses this group of SL resources to transmit multiple SL data. Before the network device releases this group of SL resources, the terminal can always use this group of SL resources.

[0165] It should be noted that in order to support dynamic scheduling resource allocation, DCI format "3-0" can be introduced in New Radio Vehicle to X (NR-V2X). The DCI in this format is used to schedule the transmission resources and parameters of the NR Physical Sidelink Control Channel (PSCCH) and the NR Physical Sidelink Shared Channel (PSSCH). In addition, this DCI can also be used for the activation and release of SL configuration authorization.

[0166] Figure 3 It is a schematic diagram of the scenario where the terminal autonomously selects transmission resources in the related art. Figure 4 It is a schematic diagram of resource selection in mode 2 in the related art. For example, Figure 3 and Figure 4 As shown, in the scenario of mode 2, the terminal autonomously selects transmission resources. The terminal can rely on random selection or resource listening to select transmission resources from the resource pool configured or pre-configured by the network device.

[0167] In mode 2, the sending terminal decodes the SCI sent by other terminals and measures the SL received power, and selects resources in the resource pool that are not reserved by other terminals or are reserved but have a lower received power, so as to complete resource selection based on resource reservation, resource listening, and resource exclusion.

[0168] It should be understood that for resource sensing in mode 2, the terminal can first determine a candidate resource set, and then select transmission resources from the candidate resource set. Among them, the process of the terminal determining the candidate resource set can include the terminal excluding resources according to the unlistened time slots, and the terminal excluding resources according to the first-order SCI it has listened to.

[0169] It should be understood that since mode2 does not depend on the network, the resource selection work can be carried out in a scenario without network deployment, which can also reduce the scheduling delay and relieve the load of network devices.

[0170] However, with the introduction of Frequency Range 2 (FR2), the wired antenna will become the standard configuration of the SL terminal. In related technologies, whether it is unified scheduling on the network side or autonomous selection by the terminal, the resource awareness of SL is based on the full-coverage characteristic of the omnidirectional antenna of the SL terminal, and the resource awareness of the directional antenna cannot be realized.

[0171] To solve the above technical problems, the embodiments of the present application provide a method, device, apparatus, and storage medium for determining transmission resources. Since during resource awareness, within the directional coverage range of the directional antenna, resource avoidance is performed based on resource occupancy information, considering the directional factor of the directional antenna, the resource awareness of the directional antenna is thus realized.

[0172] The method for determining transmission resources provided by the embodiments of the present application can be applied to an application environment such as Figure 5 and Figure 6 shown. Among them, this scenario includes a first terminal 101, a second terminal 102, a third terminal 103, and a network device 104.

[0173] As Figure 5 shown, when the first terminal 101 needs to perform SL communication with the third terminal 103 as the receiving end (RX) as the sending end (TX), the first terminal 101 can receive the resource occupancy information sent by the second terminal 102, and this resource occupancy information is used to determine the resources to be avoided within the directional coverage range corresponding to the directional antenna of the first terminal 101. Subsequently, the first terminal 101 determines the optional transmission resources for the first terminal to perform SL communication with the third terminal 103 according to the resource occupancy information.

[0174] As Figure 6 shown, when the first terminal 101 needs to perform SL communication with the third terminal 103 as the receiving end (RX) as the sending end (TX), the second terminal 102 can send the resource occupancy information to the network device 104, and this resource occupancy information is used to determine the resources to be avoided within the directional coverage range corresponding to the directional antenna of the first terminal 101. Subsequently, the network device 104 schedules optional transmission resources for the first terminal 101 according to the resource occupancy information.

[0175] The first terminal 101, the second terminal 102, and the third terminal 103 involved in the embodiments of the present application may be devices that provide voice and / or data connectivity to users, such as handheld devices with wireless connection capabilities, or other processing devices connected to a wireless modem. In different systems, the names of terminal devices may also be different. For example, in a 5G system, a terminal device may be referred to as a user equipment (UE).

The system may also include a core network part, such as an Evolved Packet System (EPS), a 5G System (5GS), etc.

[0178] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0179] In one embodiment, as Figure 7 shown, a signaling interaction diagram of a method for determining transmission resources is provided. The method for determining transmission resources is used to illustrate how to determine transmission resources when a terminal selects autonomously. The method for determining transmission resources includes S201 - S202:

[0180] S201. The second terminal sends resource occupancy information to the first terminal, and the resource occupancy information is used to determine the resources to be avoided within the directional coverage range corresponding to the directional antenna of the first terminal.

[0181] In the present application, if the terminal selects transmission resources autonomously, the second terminal may send resource occupancy information to the first terminal, so that when the first terminal performs direct link communication, the first terminal can determine the resources to be avoided within the directional coverage range corresponding to the directional antenna of the first terminal based on the resource occupancy information.

[0182] Among them, the first terminal may be the TX terminal for SL communication, and the second terminal is other neighboring terminals within the communication range of the first terminal. The second terminal may include the RX terminal for SL communication with the first terminal and other terminals that do not perform SL communication with the first terminal.

[0183] It should be understood that the second terminal may be one or multiple, and the embodiments of the present application do not limit this. When the second terminal is multiple, each second terminal can send resource occupancy information to the first terminal. When the first terminal performs resource sensing, it can respectively determine the resources to be avoided based on the resource occupancy information sent by each second terminal.

[0184] It should be understood that the directional antenna of the first terminal may be one or multiple. Since the directions of each directional antenna are different, correspondingly, the resources to be avoided within the directional coverage of each directional antenna are also different. Therefore, when the first terminal has multiple directional antennas, each directional antenna needs to respectively determine different resources to be avoided based on the resource occupancy information.

[0185] It should be understood that the embodiments of the present application do not limit the resource occupancy information, which may include any information used to determine the resources to be avoided by the directional antenna.

[0186] In some embodiments, the resource occupancy information may include the location information of the second terminal and the direction information of the directional antenna of the second terminal.

[0187] It should be understood that through the location information of the second terminal and the direction information of the directional antenna of the second terminal, the coverage range of the directional antenna of the second terminal can be determined. If there is an overlap between the coverage range of the directional antenna of the second terminal and the coverage range of the directional antenna of the first terminal, the transmission resources occupied or reserved by the directional antenna of the second terminal may be the resources to be avoided by the directional antenna of the first terminal. If there is no overlap between the coverage range of the directional antenna of the second terminal and the coverage range of the directional antenna of the first terminal, the transmission resources occupied or reserved by the directional antenna of the second terminal are not the resources to be avoided by the directional antenna of the first terminal and can be used as optional transmission resources.

[0188] It should be understood that when the resource occupancy information includes the location information of the second terminal and the direction information of the directional antenna of the second terminal, terminals performing SL communication such as the first terminal and the second terminal can retain the omnidirectional antenna and introduce the directional antenna at the same time, or can remove the omnidirectional antenna and only retain the directional antenna.

[0189] Exemplarily, the omnidirectional antenna and the directional antenna can act together in the process of SL communication. Among them, the omnidirectional antenna is applied in the Frequency range 1 (FR1) band, mainly for resource sensing and transmitting the above-mentioned resource occupancy information. The directional antenna is applied in the FR2 band, mainly for transmitting the SL Transport Block (TB) after resource selection.

[0190] Among them, the FR1 band is a low-frequency band, which can include the bands between below 6 GHz. The FR2 band is a high-frequency band, which can be the band between 24.25 GHz and 52.6 GHz.

[0191] Exemplarily, the omnidirectional antenna can also be removed, and only the directional antenna is used in the process of SL communication. Among them, multiple directional antennas can cover different directions, and the above-mentioned resource occupancy information can be polled and transmitted through the directional antennas in multiple different directions, so as to use multiple directional antennas to replace the omnidirectional antenna.

[0192] In some embodiments, the resource occupancy information may include first coordination information and / or second coordination information. The first coordination information is used to indicate the resources that the second terminal expects to occupy on the target beam, and the second coordination information is used to indicate the occupied resources sensed by the second terminal on the target beam. The target beam is the beam corresponding to the directional antenna of the first terminal.

[0193] Exemplarily, the first coordination information and / or the second coordination information may be information in Inter-UE coordination (IUC).

[0194] It should be understood that the IUC technology is a signal transmission technology between terminals, aiming to provide benefits and advantages for the resource selection mechanism of the Rel-16 standard. IUC can solve the hidden node and half-duplex problems. IUC includes IUC-1 information and IUC-2 information. The IUC-1 information is used for the preferred resources and non-preferred resources transmitted by the second terminal, and the IUC-2 information is used for transmitting the resources with expected, potential and / or detected resource conflicts indicated by the second terminal's Sidelink Control Information (SCI).

[0195] Among them, the preferred resources are the resources that the second terminal expects to occupy on the target beam, and the non-preferred resources are the occupied resources sensed by the second terminal on the target beam. Exemplarily, both the above-mentioned first coordination information and second coordination information can be IUC-1 information. The first coordination information corresponds to the preferred resources, and the first coordination information corresponds to the non-preferred resources.

[0196] In some embodiments, when the resource occupancy information includes first coordination information and / or second coordination information, the source occupancy information may be transmitted through a target beam or a beam covering the target beam.

[0197] Exemplarily, for a second terminal adjacent to a first terminal, the above resource occupancy information may be transmitted through a target beam or a beam covering the target beam by the source occupancy information. The first terminal receives the resource occupancy information and obtains the first coordination information and / or the second coordination information therefrom. Subsequently, the first terminal may exclude the resources corresponding to the first coordination information and / or the second coordination information, so as to determine the optional transmission resources of the first terminal, and select a resource from the optional transmission resources to perform SL transmission using the target beam.

[0198] In some embodiments, a specific beam may also be preset in advance. For this specific beam, the first terminal may not perform resource exclusion based on the first coordination information, and the first terminal may still use the corresponding resources for transmission to achieve spatial resource reuse gain.

[0199] It should be noted that for the first coordination information and / or the second coordination information, SL terminals such as the first terminal and the second terminal may not retain omnidirectional antennas and only use directional antennas for transmission.

[0200] In some embodiments, the resource occupancy information may include a set of paired terminals of the second terminal, and the set of paired terminals includes terminals that establish beam pairing on the target beam.

[0201] Exemplarily, both the first terminal and the second terminal may act as target terminals to send a Synchronization Signal Block (SSB) or a Channel State Information - Reference Signal (CSI - RS) to surrounding terminals. The surrounding terminals receive and feedback the S - SSB or CSI - RS, so as to establish an initial beam pairing between the target terminal and the surrounding terminals. The target terminal determines the set of terminals that can receive this beam around it. This set may be the result obtained after multiple target beams perform initial beam pairing, and this set is the above - mentioned set of paired terminals.

[0202] Exemplarily, before resource sensing, both the first terminal and each second terminal may establish an initial beam pairing by sending an SSB or CSI - RS, so as to obtain the set of paired terminals. Subsequently, the second terminal may send the set of paired terminals to the first terminal.

[0203] Among them, the index of the above paired terminal set is carried in the Sidelink Control Information (SCI). The second terminal can directly send the paired terminal set to the first terminal through the SCI, or forward the paired terminal set to the first terminal through the SCI via a network device.

[0204] S202. The first terminal determines the optional transmission resources of the first terminal according to the resource occupancy information.

[0205] In this application, after the first terminal receives the resource occupancy information sent by the second terminal, it can determine the optional transmission resources of the first terminal according to the resource occupancy information.

[0206] It should be understood that for different resource occupancy information, different methods can be used to determine the optional transmission resources of the first terminal.

[0207] In some embodiments, if the resource occupancy information includes the location information of the second terminal and the direction information of the directional antenna of the second terminal, the first terminal can first determine the directivity coverage range corresponding to the directional antenna of the second terminal according to the location information of the second terminal and the direction information of the directional antenna of the second terminal. Subsequently, the first terminal can determine the resources to be avoided according to the coverage range of the directional antenna of the second terminal and the directivity coverage range corresponding to the directional antenna of the first terminal. Finally, the first terminal can determine the optional transmission resources of the first terminal by excluding the resources to be avoided.

[0208] In some embodiments, the above location information includes information on the area where the second terminal is located within a preset communication range. Among them, the preset communication range can be the range of a preset place or the range affecting the SL communication of the first terminal.

[0209] In some embodiments, multiple areas can be divided within the above preset communication range, and the area division indicators include at least one of the following information: topographic and geomorphic information, beam information, and frequency band information.

[0210] Exemplarily, the division of areas within the above preset communication range can be preset default data. In the scenario of mode2, terminals can broadcast and determine the area division result through omnidirectional antennas or directional antennas. Or, in the scenario of mode1, the division of areas within the preset communication range can also be performed by a network device and broadcast within the preset communication range.

[0211] Among them, the above areas can be any polygons such as squares and rectangles, and the areas can be non-overlapping or overlapping with each other. The embodiments of the present application do not limit this.

[0212] It should be understood that embodiments of the present application do not limit how to determine the directivity coverage range corresponding to the directional antenna of the second terminal based on the position information of the second terminal and the direction information of the directional antenna of the second terminal. In some embodiments, based on the position information of the second terminal and the direction information of the directional antenna of the second terminal, the areas affected by all the resources occupied or reserved by the second terminal within the preset communication range can be determined, and the set of all affected areas can form the directivity coverage range corresponding to the directional antenna of the second terminal.

[0213] It should be understood that the directivity coverage range corresponding to the directional antenna of the first terminal can also be determined in advance based on the position information of the first terminal and the direction information of the directional antenna of the first terminal, and the determination method is the same as that of the directivity coverage range corresponding to the directional antenna of the second terminal, which will not be elaborated here.

[0214] It should be understood that embodiments of the present application do not limit how to determine the resources to be avoided according to the coverage range of the directional antenna of the second terminal and the directivity coverage range corresponding to the directional antenna of the first terminal. In some embodiments, if there is an overlap between the coverage range of the directional antenna of the second terminal and the directivity coverage range corresponding to the directional antenna of the first terminal, the resources occupied or reserved by the directional antenna of the second terminal can be determined as the resources to be avoided.

[0215] In some embodiments, the resource occupancy information further includes distance threshold information and / or signal strength threshold information, and both the distance threshold information and the signal strength threshold information are used to remove the invalid areas in the directivity coverage range.

[0216] Exemplarily, there is a maximum distance for the influence of resource occupancy between terminals, that is, the above-mentioned distance threshold information. The distance threshold information can determine the size of the beam coverage area. After exceeding the distance threshold, other terminals can consider that the beam coverage will fail. Correspondingly, the areas in the directivity coverage range that exceed the distance threshold can be determined as invalid areas.

[0217] It should be understood that embodiments of the present application do not limit how to determine the distance threshold information. Exemplarily, the distance threshold information can be related to parameters such as frequency band selection and maximum transmission power, and can be specifically set according to the actual situation.

[0218] Exemplarily, the farther the other terminal is, the smaller the received power. Therefore, there is a signal strength threshold information, which can be, for example, a reference signal receiving power (RSRP) threshold value. When the signal strength is lower than the signal strength threshold, other terminals can consider that the beam coverage will fail. Correspondingly, the areas in the directivity coverage range that are lower than the signal strength threshold can be determined as invalid areas.

[0219] In some embodiments, if the resource occupancy information includes first coordination information and / or second coordination information, the first terminal may first determine the resources to be avoided according to the first coordination information and / or the second coordination information. Subsequently, the first terminal determines the available transmission resources of the first terminal by excluding the resources to be avoided.

[0220] Exemplarily, all second terminals adjacent to the first terminal may transmit the first coordination information and / or the second coordination information based on their received resources, and the first coordination information and / or the second coordination information may be transmitted based on the received target beam or a beam that can cover the target beam. After receiving the first coordination information and / or the second coordination information, the first terminal may determine both the resources expected to be occupied indicated by the first coordination information and the perceived occupied resources indicated by the second coordination information as the resources to be avoided. Subsequently, after excluding the resources to be avoided, the first terminal obtains the available transmission resources and selects resources from the available transmission resources for SL transmission.

[0221] In some embodiments, specific non-preferred resources may also be set as not to be detected. Correspondingly, for the second coordination information corresponding to the specific non-preferred resources, the first terminal may not perform resource exclusion and still use these resources for transmission to achieve spatial resource reuse.

[0222] In some embodiments, if the first terminal is in the paired terminal set, the first terminal excludes the transmission resources occupied by the second terminal to determine the resources to be avoided. Subsequently, the first terminal determines the available transmission resources of the first terminal by excluding the resources to be avoided.

[0223] Exemplarily, during the resource sensing process, if the first terminal needs to use a certain target beam for transmission, it may avoid the time-frequency resources used by the terminals in the paired terminal set corresponding to the target beam, and the time-frequency resources used by the terminals not in the paired terminal set corresponding to the target beam do not need to be avoided.

[0224] In the method for determining transmission resources provided by the embodiments of the present application, the first terminal first receives the resource occupancy information sent by the second terminal, and the resource occupancy information is used to determine the resources to be avoided within the directivity coverage range of the directional antenna of the first terminal. Subsequently, the first terminal determines the available transmission resources of the first terminal according to the resource occupancy information. Since during resource sensing, within the directivity coverage range of the directional antenna, resource avoidance is performed based on the resource occupancy information, considering the directivity factor of the directional antenna, resource sensing of the directional antenna is thus achieved.

[0225] The following will separately describe different resource occupancy information under mode2.

[0226] Figure 8This is a signaling interaction diagram for another method of determining transmission resources provided by an embodiment of the present application. As Figure 8 shown, the method for determining the transmission resources includes S301 - S304:

[0227] S301. The first terminal sends the area division result of the preset communication range to the second terminal.

[0228] It should be understood that the embodiments of the present application do not limit how to divide the area of the preset communication range. In some embodiments, the division indicators of the above - mentioned area include at least one of the following information: topographic and geomorphic information, beam information, and frequency band information.

[0229] Exemplarily, Figure 9 This is a schematic diagram of an area division provided by an embodiment of the present application. As Figure 9 shown, the preset communication range is divided into first - level areas and second - level areas. The length L and width W of each first - level area can be determined in advance. For example, both L and W are set to 20 meters. Multiple first - level areas can form a second - level area. The number of first - level areas in the length dimension of each second - level area can be set by Nx, and the number of first - level areas in the width dimension of each second - level area can be set by Ny. The Nx and Ny of different second - level areas can be the same or different. Among them, the values of L, W, Nx, and Ny can all change based on the values of the above - mentioned area division indicators.

[0230] Among them, the above - mentioned area can be any polygon such as a square or a rectangle. The areas can be non - overlapping or overlapping with each other. The embodiments of the present application do not limit this. The area of the above - mentioned area can be determined based on the frequency band. The higher the frequency band, the smaller the effective transmission angle of the directional antenna, and the smaller the area of each area.

[0231] Exemplarily, after the area division is completed, the divided areas can also be numbered to facilitate determining whether the directional coverage ranges overlap. Correspondingly, the first terminal can send the position and number of each area, as well as the values of the above - mentioned L, W, Nx, and Ny as the area division result to the second terminal.

[0232] S302. The second terminal sends the position information of the second terminal and the direction information of the directional antenna of the second terminal to the first terminal.

[0233] In some embodiments, after receiving the area division result, the second terminal may determine the area where the second terminal is located within the preset communication range based on the area division result, and use the area where the second terminal is located within the preset communication range as the location information of the second terminal. At the same time, the second terminal may also determine the direction information of each directional antenna. After determining the location information and the direction information, the second terminal may use an omnidirectional antenna to send the above information in a low frequency band, or use multiple directional antennas with different directions to poll and transmit the above information.

[0234] In the present application, since the coverage range of the low frequency band is wider, transmitting the location information of the second terminal and the direction information of the directional antenna of the second terminal through the omnidirectional antenna can ensure that terminals within a relatively large range receive the information. By polling and transmitting the location information of the second terminal and the direction information of the directional antenna of the second terminal through the directional antenna, the second terminal can dispense with the omnidirectional antenna and only use the directional antenna to complete resource sensing.

[0235] Exemplarily, Figure 10 FIG. [X] is a schematic diagram of the coverage range of an omnidirectional antenna provided by an embodiment of the present application. Figure 11 FIG. [X] is a schematic diagram of the coverage range of a directional antenna provided by an embodiment of the present application. Figure 12 FIG. [X] is another schematic diagram of the coverage range of an omnidirectional antenna provided by an embodiment of the present application.

[0236] As Figure 10 、 Figure 11 and Figure 12 shown, multiple directional antennas can be used to provide beam coverage in different directions to replace the broadcast effect of the omnidirectional antenna. The lower the frequency band selected by the directional antenna, the larger its coverage angle, and the corresponding larger the coverage range. When using the FR2 high frequency band, multiple directional antennas are required to provide small-angle coverage in different directions.

[0237] S303. The first terminal determines the directivity coverage range corresponding to the directional antenna of the second terminal according to the location information of the second terminal and the direction information of the directional antenna of the second terminal.

[0238] Figure 13A schematic diagram of a directional coverage range provided by an embodiment of this application. The second terminal may be a user equipment (UE) 1. UE1 is located at the intersection of area A-10 and area A-15, and UE1 communicates with UE2. The direction of the directional antenna of UE1 is ±45 degrees, and the elevation angle is not considered. Then the affected areas are A-15, area B-12, area B-13, area C-3, area C-7, and area D. Correspondingly, the above areas form the directional coverage range corresponding to the directional antenna of the second terminal. Correspondingly, the terminals in the corresponding areas, as well as the terminals that also cover the above directional coverage range, need to exclude the resources selected by UE1.

[0239] In some embodiments, the resource occupancy information further includes distance threshold information and / or signal strength threshold information, and both the distance threshold information and the signal strength threshold information are used to remove invalid areas in the directional coverage range.

[0240] Exemplarily, the above distance threshold information is used to determine the size of the directional coverage range. After exceeding the distance threshold, other terminals will consider that the directional coverage range of the target beam of the second terminal fails. Due to the existence of the distance threshold information, the directional coverage range can be a sector, and the resource pool can be divided accordingly. Among them, the distance threshold information is related to parameters such as frequency band selection and maximum transmit power.

[0241] Exemplarily, within the beam coverage range, the farther away from the second terminal, the smaller the received power. Therefore, there is a signal strength threshold information. When the signal strength is lower than the signal strength threshold, this area and the areas at farther distances can use the same resource pool of the second terminal.

[0242] It should be understood that both the distance threshold information and the signal strength threshold information can assist the first terminal in determining whether the beam coverage of the second terminal fails. As long as one of them is satisfied, the first terminal can consider that there is no need to avoid the corresponding time-frequency resources occupied by the second terminal.

[0243] In some embodiments, in addition to including the location information of the second terminal and the direction information of the directional antenna of the second terminal, the resource occupancy information may also include the area division result and the own ability information of the second terminal, such as the transmit power of the directional antenna, etc.

[0244] S304. The first terminal determines the resources to be avoided according to the coverage range of the directional antenna of the second terminal and the directional coverage range corresponding to the directional antenna of the first terminal.

[0245] In some embodiments, if the directional coverage range corresponding to the directional antenna of the first terminal coincides with the coverage range of the directional antenna of the second terminal, the resources corresponding to the target beam of the second terminal can be determined as the resources to be avoided.

[0246] S305. The first terminal determines the optional transmission resources of the first terminal by excluding the resources to be avoided.

[0247] In the embodiments of the present application, due to the spatial gain brought by the sectorization for the directional antenna, compared with the related art where an omnidirectional antenna is used for resource sensing, once a certain terminal occupies time-frequency resources, other terminals within the coverage range of the omnidirectional antenna need to avoid these time-frequency resources. In the method for determining transmission resources provided in the present application, when using a directional antenna, only the resources occupied by the terminals within the directional coverage range in the corresponding direction need to be avoided, thus obtaining a spatial gain.

[0248] Figure 14 FIG. is a signaling interaction diagram of another method for determining transmission resources provided in the embodiments of the present application. As Figure 14 shown, this method for determining transmission resources includes S401 - S404:

[0249] S401. The second terminal sends the first coordination information and / or the second coordination information to the first terminal.

[0250] Among them, the first coordination information is used to indicate the resources that the second terminal expects to occupy on the target beam, and the second coordination information is used to indicate the occupied resources sensed by the second terminal on the target beam. The target beam is the beam corresponding to the directional antenna of the first terminal.

[0251] Exemplarily, the first coordination information and / or the second coordination information can be information in Inter - UE coordination (IUC). The resources that the second terminal expects to occupy on the target beam can be the preferred resources in IUC - 1 information, and the occupied resources sensed by the second terminal on the target beam can be the non - preferred resources in IUC - 1 information. Exemplarily, the second terminal can determine the messages of the preferred and non - preferred resources based on its received resources.

[0252] In some embodiments, the first coordination information and / or the second coordination information can be transmitted through the target beam or the beam covering the target beam.

[0253] S402. The first terminal determines the resources to be avoided according to the first coordination information and / or the second coordination information.

[0254] In some embodiments, the first terminal can exclude the resources corresponding to the first coordination information and / or the second coordination information, so as to determine the optional transmission resources of the first terminal.

[0255] In some embodiments, specific beams may be pre-given. For such specific beams, the first terminal may not perform resource exclusion based on the first coordination information, and the first terminal may still use the corresponding resources for transmission to achieve spatial resource reuse gain.

[0256] S403. The first terminal determines the optional transmission resources of the first terminal by excluding the resources to be avoided.

[0257] S404. The first terminal selects resources from the optional transmission resources for transmission.

[0258] In some embodiments, the first coordination information and / or the second coordination information between terminal devices may be relayed and transmitted by other terminals. Figure 15 The following is a schematic diagram of a relay transmission provided by an embodiment of the present application. As Figure 15 shown, if UE1 and UE3 cannot communicate directly currently, then UE2 may be used as a transmission relay to transmit the first coordination information and / or the second coordination information of UE1 and UE3.

[0259] In the present application, when the first terminal can detect the first coordination information and / or the second coordination information transmitted by the second terminal through the target beam or a beam covering the target beam, it may be determined that the resources corresponding to the first coordination information and / or the second coordination information may interfere with the transmission of the first terminal. Therefore, the first terminal may perform avoidance to avoid resource collision.

[0260] Figure 16 The following is a signaling interaction diagram of another method for determining transmission resources provided by an embodiment of the present application. As Figure 16 shown, this method for determining transmission resources includes S501 - S504:

[0261] S501. The second terminal determines a set of paired terminals.

[0262] Exemplarily, the resource awareness process may be incorporated into the initial beam pairing process. During the initial beam pairing process, the second terminal may record the beam scanning information it receives. The beam scanning information carries the sender identifier and the corresponding beam identifier, and the second terminal may include the sender identifier and the beam identifier in the set of paired terminals.

[0263] Exemplarily, UE1 sends S-SSB or CSI-RS, and surrounding UEs receive and feedback. After this process, UE1 establishes an initial beam pairing with other UEs within a certain range, and UE1 obtains the corresponding set A1 of UEs that can receive this beam within the surrounding area. This set A1 may be the result obtained after performing the initial beam pairing for multiple beams. In turn, all terminals i can obtain the corresponding set Ai.

[0264] Exemplarily,Figure 17 This is a schematic diagram of initial beam pairing provided by an embodiment of the present application. As Figure 17 shown, UE3 performs beam pairing with UE1 and UE2 simultaneously. Then, UE1 and UE2 are included in the corresponding set A3 of UE3, that is, A3 ∋ (UE1, UE2, UE3). However, UE1 only communicates with UE3, so A1 ∋ (UE1, UE3).

[0265] In some embodiments, the paired terminal set is updated at a set time interval or when beam switching occurs, and the timing of the set time interval is refreshed after beam switching.

[0266] Among them, the above time interval can be 1 minute, 10 minutes, etc., and the embodiments of the present application do not limit this. In the present application, since the set time interval can be re-timed after beam switching triggers an update, an ineffective update process can be avoided.

[0267] S502. The second terminal sends the paired terminal set to the first terminal.

[0268] Among them, the index of the paired terminal set is carried in the direct link control information.

[0269] S503. If the first terminal is in the paired terminal set, the first terminal excludes the transmission resources occupied by the second terminal to determine the resources to be avoided.

[0270] Exemplarily, the first terminal can perform resource avoidance or resource occupation based on the paired terminal set of the first terminal and the received paired terminal set of the second terminal. When the first terminal is in the paired terminal set of a certain second terminal and the second terminal occupies a certain time-frequency resource, the first terminal can determine the time-frequency resource occupied by the second terminal as the resource to be avoided.

[0271] Exemplarily, Figure 18 This is a schematic diagram of determining resources to be avoided provided by an embodiment of the present application. As Figure 18 shown, when UE4 and UE5 communicate, in a specific time-frequency resource, the paired terminal sets A4 and A5 only contain UE4 and UE5. Therefore, they can use the same time-frequency resource as UE1 without causing conflicts.

[0272] S504. The first terminal determines the optional transmission resources of the first terminal by excluding the resources to be avoided.

[0273] The method for determining transmission resources provided by the embodiments of the present application is as follows. First, the first terminal receives the resource occupancy information sent by the second terminal, and this resource occupancy information is used to determine the resources to be avoided within the directional coverage range corresponding to the directional antenna of the first terminal. Subsequently, the first terminal determines the optional transmission resources of the first terminal according to the resource occupancy information. Since during resource sensing, within the directional coverage range of the directional antenna, resource avoidance is performed based on the resource occupancy information, considering the directional factor of the directional antenna, the resource sensing of the directional antenna is thus realized.

[0274] The methods for determining transmission resources provided in the present application all achieve non-interfering transmissions of multiple terminals in the same space. Since under the same conditions, the transmission range of the directional antenna is farther and the signal-to-noise ratio is higher, compared with the omnidirectional antenna, the resource sensing gain using the directional antenna in the present application is higher.

[0275] In one embodiment, as Figure 19 shown, a signaling interaction diagram of another method for determining transmission resources is provided. This method for determining transmission resources is used to illustrate how to schedule transmission resources through a network device. This method for determining transmission resources includes S601 - S602:

[0276] S601. The second terminal sends resource occupancy information to the network device, and the resource scheduling request is used to determine the resources to be avoided within the directional coverage range corresponding to the directional antenna of the first terminal.

[0277] It should be understood that the embodiments of the present application do not limit the resource occupancy information.

[0278] In some embodiments, the resource occupancy information includes the location information of the second terminal and the direction information of the directional antenna of the second terminal.

[0279] Among them, the location information includes the information of the area where the second terminal is located within the preset communication range. The preset communication range includes multiple areas, and the division indicators of the areas include at least one of the following information: topographic and geomorphic information, beam information, and frequency band information. The resource occupancy information is transmitted through the omnidirectional antenna of the second terminal, or the resource occupancy information is transmitted by polling through multiple directional antennas with different directions of the second terminal.

[0280] In some embodiments, the resource occupancy information further includes distance threshold information and / or signal strength threshold information, and both the distance threshold information and the signal strength threshold information are used to remove invalid areas in the directional coverage range.

[0281] In some embodiments, the resource occupancy information includes first coordination information and / or second coordination information. The first coordination information is used to indicate the resources that the second terminal expects to occupy on the target beam, and the second coordination information is used to indicate the occupied resources sensed by the second terminal on the target beam. The target beam is the beam corresponding to the directional antenna of the first terminal.

[0282] Wherein, the resource occupancy information further includes the directional antenna parameters of the second terminal and the pose information of the second terminal. The directional antenna parameters of the second terminal and the pose information of the second terminal are used to determine an auxiliary terminal adjacent to the first terminal. The auxiliary terminal is used to assist in transmitting the signal of the network device to the first terminal through third coordination information when the network device is not within the directivity coverage range corresponding to the directional antenna of the first terminal.

[0283] In some embodiments, the resource occupancy information includes a paired terminal set of the second terminal, and the paired terminal set includes terminals that establish beam pairing on the target beam.

[0284] Wherein, the index of the paired terminal set is carried in the direct link control information.

[0285] S602. The network device schedules optional transmission resources for the first terminal according to the resource occupancy information. The optional transmission resources are used for direct link communication between the first terminal and the third terminal.

[0286] In some embodiments, if the resource occupancy information includes the location information of the second terminal and the direction information of the directional antenna of the second terminal, the network device may first determine the directivity coverage range corresponding to the directional antenna of the second terminal according to the location information of the second terminal and the direction information of the directional antenna of the second terminal. Subsequently, the network device may determine the resources to be avoided according to the coverage range of the directional antenna of the second terminal and the directivity coverage range corresponding to the directional antenna of the first terminal. Finally, the network device may determine the optional transmission resources of the first terminal by excluding the resources to be avoided.

[0287] In some embodiments, if the resource occupancy information includes the first coordination information and / or the second coordination information, the network device may determine the resources to be avoided according to the first coordination information and / or the second coordination information. Subsequently, the network device determines the optional transmission resources of the first terminal by excluding the resources to be avoided.

[0288] In some embodiments, if the resource occupancy information includes the paired terminal set of the second terminal, when the first terminal or the third terminal is in the paired terminal set, the network device excludes the transmission resources occupied by the second terminal to determine the resources to be avoided. Subsequently, the network device schedules optional transmission resources for the first terminal by excluding the resources to be avoided.

[0289] In the method for determining transmission resources provided by the embodiments of the present application, the network device receives resource occupancy information sent by the second terminal. The resource scheduling request is used to determine the resources to be avoided within the directional coverage range of the directional antenna of the first terminal. Subsequently, the network device schedules optional transmission resources for the first terminal according to the resource occupancy information. The optional transmission resources are used for direct link communication between the first terminal and the third terminal. Since during resource sensing, within the directional coverage range of the directional antenna, resource avoidance is performed based on the resource occupancy information, the directional factor of the directional antenna is considered, thereby realizing resource sensing of the directional antenna.

[0290] The following will separately describe different resource occupancy information under mode1.

[0291] Figure 20 As shown in the signaling interaction diagram of another method for determining transmission resources provided by the embodiments of the present application, Figure 20 as shown, this method for determining transmission resources includes S701 - S705:

[0292] S701. The network device sends the area division result of the preset communication range to the second terminal.

[0293] S702. The second terminal sends the location information of the second terminal and the direction information of the directional antenna of the second terminal to the network device.

[0294] The second terminal can use an omnidirectional antenna to send the location information of the second terminal and the direction information of the directional antenna of the second terminal in the low frequency band, or can use multiple directional antennas with different directions to poll and transmit the location information of the second terminal and the direction information of the directional antenna of the second terminal.

[0295] S703. The network device determines the directional coverage range corresponding to the directional antenna of the second terminal according to the location information of the second terminal and the direction information of the directional antenna of the second terminal.

[0296] In some embodiments, the second terminal can also report the current attitude of the second terminal to the network device, and the current attitude of the second terminal can be used to determine the rotation angle of the second terminal.

[0297] S704. The network device determines the resources to be avoided according to the coverage range of the directional antenna of the second terminal and the directional coverage range corresponding to the directional antenna of the first terminal.

[0298] S705. The network device determines the optional transmission resources of the first terminal by excluding the resources to be avoided.

[0299] Figure 21 As shown in the signaling interaction diagram of another method for determining transmission resources provided by the embodiments of the present application, Figure 21As shown, the method for determining the transmission resource includes S801 - S804:

[0300] S801. The second terminal sends the first coordination information and / or the second coordination information to the network device.

[0301] In some embodiments, due to the directional coverage range problem of the directional antenna, even if the second terminal is within the coverage range of the network device, it may still be unable to receive signals. Therefore, the IUC needs to be used to assist signal transmission with the help of adjacent terminals.

[0302] Exemplarily, Figure 22 is a schematic diagram of resource awareness assisted by the IUC provided in the embodiments of the present application. As Figure 22 shown, due to the directional coverage range problem of the directional antenna, UE2 cannot communicate with the network device. At this time, UE2 can use the IUC to assist in transmitting signals to the network device with the help of the adjacent UE1.

[0303] S802. The network device determines the resources to be avoided according to the first coordination information and / or the second coordination information.

[0304] S803. The network device determines the optional transmission resources of the first terminal by excluding the resources to be avoided.

[0305] S804. The network device selects resources for transmission from the optional transmission resources.

[0307] S901. The second terminal determines the paired terminal set.

[0308] S902. The second terminal sends the paired terminal set to the network device.

[0309] S903. If the first terminal or the third terminal is in the paired terminal set, the network device excludes the transmission resources occupied by the second terminal to determine the resources to be avoided.

[0310] Exemplarily, after the network device confirms the communication request from UE1 to UE3, if it needs to use the same time - frequency resources to schedule the second group of terminal pairs (for example, the transmission request from UEi to UEj), then in the paired terminal sets Ai corresponding to UEi and Aj corresponding to UEj, UE1 and UE3 cannot be included, otherwise the resources cannot be used.

[0311] S904. The network device schedules optional transmission resources for the first terminal by excluding the resources to be avoided.

[0312] In the method for determining transmission resources provided in the embodiment of the present application, a network device receives resource occupancy information sent by a second terminal, and a resource scheduling request is used to determine the resources to be avoided within the directional coverage range corresponding to the directional antenna of the first terminal. Subsequently, the network device schedules optional transmission resources for the first terminal based on the resource occupancy information, and the optional transmission resources are used for direct link communication between the first terminal and the third terminal. During resource perception, resource avoidance is performed based on resource occupancy information within the directional coverage range of the directional antenna, and the directional factor of the directional antenna is taken into account, thereby realizing resource perception of the directional antenna.
