[0114] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0115] The method for communicating based on an auxiliary resource set provided in the embodiment of the present disclosure can be applied to Figure 1 Direct communication system shown. Figure 1 As shown, in the scenario where direct communication devices perform direct communication, the network device configures various transmission parameters for data transmission for the direct communication device 1. The direct communication device 1, the direct communication device 2 and the direct communication device 3 perform direct communication. There may be obstacles between the direct communication device 2 and the direct communication device 3. The link for communication between the network device and the direct communication device is an uplink and a downlink, and the link between the direct communication device and the direct communication device is a sidelink.

[0116] In the present disclosure, the communication scenario of direct communication between directly connected communication devices can be a vehicle-to-everything (V2X) business scenario. Among them, V represents the vehicle-mounted device, and X represents any object that interacts with the vehicle-mounted device. Currently, X mainly includes vehicle-mounted devices, handheld devices, traffic roadside infrastructure and networks. The information mode of V2X interaction includes: interaction between vehicle-mounted devices and vehicle-mounted devices (Vehicle to Vehicle, V2V), between vehicle-mounted devices and roadside devices (Vehicle to Infrastructure, V2I), between vehicle-mounted devices and handheld devices (Vehicle to Pedestrian, V2P), and between vehicle-mounted devices and networks (Vehicle to Network, V2N).

[0117] With the development of the new generation of 5G mobile communication technology, 5G NR technology is used in 3GPP Rel-16 to support new V2x communication services and scenarios, such as fleet management (Vehicles Platooning), perception extension (Extended Sensors), advanced driving (Advanced Driving), and remote driving (remote driving). In general, 5G V2x sidelink can provide higher communication rates, shorter communication delays, and more reliable communication quality.

[0118] The communication scenario of direct communication between directly connected communication devices can also be a device-to-device (D2D) communication scenario. The directly connected communication devices for 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 a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), terminals, terminal equipment, etc. For the convenience of description, the embodiments of the present disclosure are described below using the direct communication device as a user equipment as an example.

[0119] Among them, the enhancement of NR Sidelink can improve transmission reliability and reduce latency. In the enhancement of NR Sidelink, in terms of enhancing Mode2 resource allocation, the 3GPP working group reached the conclusion that a way for user equipment to assist in resource selection needs to be studied. In this way, two user equipments are specified. For example, user equipment A is the assisting user equipment of user equipment B, and user equipment B is the user equipment that needs to select resources for the data to be sent by itself. Among them, user equipment A will determine a resource set and send it to user equipment B in the mode of mode 2. When user equipment B makes resource selection, it will consider the resource set sent by user equipment A, that is, it can be understood that user equipment B uses the assisted resource set assistance mechanism to make resource selection, realizing a communication method based on the assisted resource set. Among them, user equipment B can send data to user equipment A and / or other user equipments.

[0120] For the convenience of description, in the embodiments of the present disclosure, the user equipment (user equipment A) that provides the assisted resource set is called the first user equipment, and the user equipment (user equipment B) that makes resource selection based on the assisted resource set is called the second user equipment.

[0121] In the related art, in the solution for communication based on the assisted resource set, the window start time domain position n'+T'_1 of the resource selection window for the first user equipment to send the assisted resource set is defined, and the window end time domain position n'+T'_2 of the resource selection window is defined. At the same time, the window start time domain position n+T_1 of the resource selection window where the assisted resources indicated in the assisted resource set are used by the second user equipment, and the window end time domain position n+T_2 are defined.

[0122] In the solution for communication based on the assisted resource set, a communication method for the assisted resource set between user equipments based on an assisted request is provided, and a communication method for the assisted resource set between user equipments based on conditions is also provided. Among them, for the communication method for the assisted resource set between user equipments based on an assisted request, (n'+T'_2)≤X2. For the communication method for the assisted resource set based on conditions, (n'+T'_2)<X3. Among them, X2 and X3 are the window end time domain positions of the resource selection window. The 108b-e meeting proposed to study the values of X2 and X3, that is, the window end time domain position of the resource selection window needs to be defined.

[0123] At the same time, in the related art, the resource awareness window for the second user equipment to determine the assisted resource set is: [(n+T_1)–T_0–T”_1,(n+T_1)–T_proc,0–T”_1].

[0124] Figure 2FIG. 1 shows a schematic diagram of a time domain location involved in communication based on an auxiliary resource set in an exemplary embodiment of the present disclosure. Figure 2 As shown, the resource selection window for the first user equipment to send the auxiliary resource set is [n'+T'_1, n'+T'_2]. The resource selection window for the second user equipment to use the auxiliary resources indicated in the auxiliary resource set is [n+T_1, n+T_2]. The resource perception window for the second user equipment to determine the auxiliary resource set is: [(n+T_1)–T_0–T”_1, (n+T_1)–T_proc,0–T”_1]. Therefore, the difference between the window start time domain position of the resource selection window of the auxiliary resource set sent by the first user equipment and the window end time domain position of the resource perception window of the auxiliary resource set is T_proc,0+T”_1, and the difference between the window start time domain position of the resource perception window of the auxiliary resource set determined by the second user equipment and the window end time domain position of the resource perception window of the auxiliary resource set is also T_proc,0+T”_1. Therefore, this method causes [n'+T'_1,(n'+T'_2)] and [(n+T_1),(n+T_2)] to overlap. Therefore, after the second user equipment receives the auxiliary resource set of the first user equipment, the resource set indicated in the auxiliary resource set may be outdated and cannot be used. For example, Figure 2 In the method, the resource set indicated in the auxiliary resource set of the first user equipment includes the position P1 of the first resource, the position P2 of the second resource, and the position P3 of the third resource in the resource combination. The time domain position at which the first user equipment actually sends the auxiliary resource set is after the position P1 of the first resource, the position P2 of the second resource, and the position P3 of the third resource in the first resource combination, resulting in that when the second user equipment receives the auxiliary resource set and uses the auxiliary resource, P1, P2, and P3 in the first resource combination are outdated and cannot be used. Each resource combination is a time resource indication (TRIV) and a frequency resource indication (FRIV) and a resource reservation period, and a combined resource indication method, wherein one TRIV is a reused time domain resource indication method in R16, indicating the time domain positions of n resources in the resource combination, and FRIV is a reused frequency domain resource indication method in R16, indicating the frequency domain positions of n resources in the resource combination, that is, indicating the subchannels at which the n resources start to be occupied and the number of occupied subchannels.

[0125] Among them, in the embodiment of the present disclosure, n+T1 is the starting time domain position of the resource selection window of the second user equipment, or it can also be understood as the starting time domain position of the resource selection window of the auxiliary resource set determined by the first user equipment. n+T2 is the ending time domain position of the resource selection window of the second user equipment, or it can also be understood as the starting time domain position of the resource selection window of the auxiliary resource set determined by the first user equipment. (n'+T'_1) is the starting time domain position of the resource selection window for the first user equipment to send the auxiliary resource set. (n'+T'_2) is the ending time domain position of the resource selection window for the first user equipment to send the auxiliary resource set. T"_1 is the time pre-configured by the network device, reusing the value specified by the sidelink in R16. T_proc,0 is the time for processing the perception result of the user equipment, which is the time pre-configured by the network device, reusing the value specified by the sidelink in R16. n' is the time domain position of the sending resource of the auxiliary resource set determined by the first user equipment at the time domain position n.

[0126] Based on the above problem that the resources indicated in the auxiliary resource set are outdated, an embodiment of the present disclosure provides a method for communicating based on an auxiliary resource set. In this method, a first user device determines a window end domain position of a resource selection window based on a specified time domain position offset, and sends an auxiliary resource set to a second user device based on the window end domain position. The second user device receives the auxiliary resource set sent by the first user device based on the window end domain position, thereby improving the situation where the auxiliary resources indicated in the auxiliary resource set are outdated and cannot be used because they are received after the window end domain position.

[0127] Figure 3 is a flow chart of a method for communication based on an auxiliary resource set according to an exemplary embodiment. Figure 3 As shown, the method for communicating based on the auxiliary resource set is used in a first user equipment, and includes the following steps.

[0128] In step S11, a window end time domain position of a resource selection window is determined, the resource selection window is a time window in which the first user equipment sends a secondary resource set to the second user equipment, and the window end time domain position is determined based on a specified time domain position offset.

[0129] In step S12, a secondary resource set is sent to the second user equipment based on the window end domain position.

[0130] In the embodiment of the present disclosure, the first user equipment determines the window end time domain position of the resource selection window based on the specified time domain position offset, and sends an auxiliary resource set to the second user equipment based on the window end time domain position. This can improve the situation where the auxiliary resources indicated in the auxiliary resource set are received after the window end time domain position, resulting in the auxiliary resources being outdated and unable to be used, and improve the communication performance based on the auxiliary resource set.

[0131] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, a window end domain position of a resource selection window is defined to prevent the auxiliary resources indicated in the auxiliary resource set from being received after the window end domain position.

[0132] Figure 4 is a flow chart of a method for communication based on an auxiliary resource set according to an exemplary embodiment. Figure 4 As shown, the method for communicating based on the auxiliary resource set is used in a first user equipment, and includes the following steps.

[0133] In step S21, the window end time domain position of the resource selection window is determined based on the first time domain position and the first time domain position offset.

[0134] In step S22, a secondary resource set is sent to the second user equipment based on the window end domain position.

[0135] The first time domain position is determined based on the time domain position corresponding to the resources indicated in the auxiliary resource set, and the first time domain position offset is determined based on the time when the second user equipment decodes the auxiliary resource set.

[0136] In the following, Pm is used to represent the first time domain position determined based on the time domain position corresponding to the resource indicated in the auxiliary resource set. ΔT is used to represent the first time domain position offset determined by the time when the second user equipment decodes the auxiliary resource set. n'+T2' is still used to represent the window end time domain position of the resource selection window for sending the auxiliary resource set by the first user equipment.

[0137] In the method for communication based on auxiliary resource sets provided by the embodiment of the present disclosure, n'+T2' is determined based on Pm and ΔT, wherein Pm is related to the time domain position of the auxiliary resources indicated in the auxiliary resource set, and ΔT can be understood as the time for decoding the auxiliary resource set (IUC, inter UE coordination).

[0138] In the method for communicating based on an auxiliary resource set provided by the embodiment of the present disclosure, n'+T2' may be a time domain position corresponding to the first time domain position minus the first time domain position offset, that is, n'+T2'=Pm-ΔT.

[0139] In the method for communicating based on an auxiliary resource set provided by the embodiment of the present disclosure, n'+T2' may be a time domain position that is earlier than the first time domain position and reduced by the first time domain position offset, that is, n'+T2'<Pm-ΔT.

[0140] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the time domain position Pm corresponding to the resources indicated in the auxiliary resource set can be, on the one hand, the time domain position of the auxiliary resource indicated based on the resource combination, and on the other hand, it can also be the time domain position of the auxiliary resource set directly indicated in the auxiliary resource set.

[0141] In the embodiment of the present disclosure, the number of resource combinations is at most 2, and the number of resources indicated in each resource combination is at most 3.

[0142] In one implementation, in the method for communication based on an auxiliary resource set provided by an embodiment of the present disclosure, Pm is the time domain position of the nth resource in the mth resource combination indicated in the auxiliary resource set. Wherein, the value of n is a positive integer less than or equal to 3. When the auxiliary resource set is carried by control information, the value of m is a positive integer less than or equal to 2, and when the auxiliary resource set is carried by a medium access control (MAC) control element (CE), the value of m is ≤M, and M is determined according to the indication of the network device.

[0143] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, in order to reduce the probability of receiving the auxiliary resource indicated in the auxiliary resource set after the time domain position at the end of the window, Pm is the time domain position of the resource in the first resource combination indicated in the auxiliary resource set. That is, the value of m is 1.

[0144] In the method for communicating based on the auxiliary resource set provided by the embodiment of the present disclosure, in order to reduce the probability of receiving the auxiliary resource indicated in the auxiliary resource set after the time domain position at the end of the window, Pm is the time domain position of the first resource in the resource combination indicated in the auxiliary resource set. That is, the value of n is 1.

[0145] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, in order to reduce the probability of receiving the auxiliary resource indicated in the auxiliary resource set after the time domain position at the end of the window, Pm is the time domain position of the first resource in the first resource combination indicated in the auxiliary resource set. That is, the value of m is 1, and the value of n is 1.

[0146] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the time domain position Pm corresponding to the resource indicated in the auxiliary resource set may be the time domain position of the auxiliary resource set directly indicated in the auxiliary resource set. For example, Pm is the time domain position of the x-th resource indicated in the auxiliary resource set, and the value of x is a positive integer less than or equal to 6.

[0147] In one implementation, in the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, in order to reduce the probability of receiving the auxiliary resource indicated in the auxiliary resource set after the time domain position at the end of the window, Pm is the time domain position of the first resource indicated in the auxiliary resource set. That is, the value of x is 1.

[0148] In the method for communicating based on auxiliary resource sets provided by the embodiments of the present disclosure, when n'+T2'=Pm-ΔT or n'+T2'<Pm-ΔT, the first user equipment sends the auxiliary resource set to the second user equipment within the resource selection window.

[0149] Figure 5 is a flow chart of a method for communication based on an auxiliary resource set according to an exemplary embodiment. Figure 5 As shown, the method for communicating based on the auxiliary resource set is used in a first user equipment, and includes the following steps.

[0150] In step S31, the window end time domain position of the resource selection window is determined based on the first time domain position and the first time domain position offset.

[0151] Among them, n'+T2'=Pm-ΔT, or n'+T2'<Pm-ΔT.

[0152] Pm is the time domain position of the nth resource in the mth resource combination indicated in the auxiliary resource set. Or Pm is the time domain position of the xth resource indicated in the auxiliary resource set.

[0153] In step S32, the auxiliary resource set is sent to the second user equipment within the resource selection window.

[0154] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, when n'+T2'=Pm-△T, or n'+T2'<Pm-△T, the window end position of the resource selection window for sending the auxiliary resource set is before the time domain position where the auxiliary resources indicated by the auxiliary resource set are located. Therefore, when the first user equipment sends the auxiliary resource set to the second user equipment within the resource selection window, it can avoid receiving the auxiliary resources indicated in the auxiliary resource set after the window end time domain position.

[0155] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, if Pm-△T<n'+value0, there may be a situation where the resource selection window for sending the auxiliary resource set is too small, resulting in insufficient window resources. At this time, the first user equipment can use randomly selected resources to send the auxiliary resource set, or give up sending the auxiliary resource set to the second user equipment within this resource selection window.

[0156] Among them, in the embodiment of the present disclosure, n' is the second time domain position, the second time domain position is the time domain position of the sending resource determined by the first user equipment to send the auxiliary resource set, and value0 is the first specified time domain offset. The first specified time domain offset is a specified number of time unit values, for example, the first specified time domain offset is 1 time slot. Or the first specified time domain offset is the minimum end time T2min of the resource selection window. Or the first specified time domain offset is the packet delay budget (PDB) value corresponding to the auxiliary resource set.

[0157] In one implementation, when the time domain offset is specified as the minimum end time T2min of the resource selection window, the first user equipment may send an auxiliary resource set to the second user equipment based on selecting random resources; or give up sending the auxiliary resource set to the second user equipment within the resource selection window.

[0158] Figure 6 A schematic diagram showing a case where a resource selection window for sending an auxiliary resource set is too small, resulting in insufficient window resources, in an exemplary embodiment of the present disclosure. Figure 6 In this example, value0 = T2min is used for explanation. Figure 6 As shown, n'+T2'<n'+T_2min, the resource selection window does not satisfy n'+T_2min≤n'+T_2, that is, the resource selection window for the first user equipment to send the auxiliary resource set is too small, and the resources in the window are insufficient. The first user equipment can send the auxiliary resource set to the second user equipment based on selecting random resources; or give up sending the auxiliary resource set to the second user equipment within the resource selection window.

[0159] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the window end position of the resource selection window for sending the auxiliary resource set is before the time domain position where the auxiliary resources indicated by the auxiliary resource set are located. Therefore, when the first user equipment sends the auxiliary resource set to the second user equipment within the resource selection window, it can avoid receiving the auxiliary resources indicated in the auxiliary resource set after the window end time domain position.

[0160] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the time domain position at the end of the window is determined based on the time domain position of the sending resource of the auxiliary resource set determined to be sent plus a specified time domain offset.

[0161] In one implementation, in the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the time domain position at the end of the window is determined based on the second time domain position and the second specified time domain offset. The second time domain position is the time domain position of the sending resource determined by the first user equipment to send the auxiliary resource set, represented by n'. The second specified time domain offset is represented by value1. The second specified time domain offset can be configured by the network device.

[0162] Figure 7 is a flow chart of a method for communication based on an auxiliary resource set according to an exemplary embodiment. Figure 7 As shown, the method for communicating based on the auxiliary resource set is used in a first user equipment, and includes the following steps.

[0163] In step S41, the window end time domain position of the resource selection window is determined based on the second time domain position and the second specified time domain offset.

[0164] The second time domain position is the time domain position of the sending resource determined by the first user equipment to send the auxiliary resource set, which is represented by n'. The second specified time domain offset is represented by value1. Value1 is the minimum end time of the resource selection window, or the second specified time domain offset is the PDB value of the auxiliary resource set.

[0165] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, in one implementation, the window ends at a time domain position corresponding to the second time domain position plus the second time domain offset. That is, n'+T2'=n'+value1. In another implementation, the window ends at a time domain position earlier than the second time domain position plus the second time domain offset corresponding to the time domain position. That is, n'+T2'<n'+value1.

[0166] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, when the window end time domain position is determined based on the second time domain position and the second specified time domain offset, it may cause the auxiliary resource indicated in the auxiliary resource set to be sent before the window end time domain position.

[0167] In one example, the time domain position corresponding to the resource indicated in the auxiliary resource set is reduced by the time domain position corresponding to the time when the second user equipment decodes the auxiliary resource set, and is earlier than the window end time domain position, which may cause the auxiliary resource set to be sent before the window end time domain position of the auxiliary resource indicated in the auxiliary resource set. In the case where the auxiliary resource set indicated in the auxiliary resource set is sent before the window end time domain position, there are outdated resources.

[0168] For the convenience of description in the embodiment of the present disclosure, the third time domain position is represented by Pn. The time when the second user equipment decodes the auxiliary resource set is still represented by ΔT.

[0169] In the embodiment of the present disclosure, in response to the third time domain position reducing the time domain position corresponding to the first time domain position offset, it is earlier than the window end time domain position, that is, when Pn-△T<n'+T2', n'+T2'<n'+value1, and there is a problem of outdated resources indicated in the auxiliary resource set.

[0170] Figure 8 A schematic diagram showing the existence of outdated resources in an exemplary embodiment of the present disclosure is shown. Figure 8 In this example, value0 = T2min is used for explanation. Figure 8 As shown, the resources indicated in the auxiliary resource set before the time domain position corresponding to n'+T2'<n'+value1 are outdated resources.

[0171] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, Pn is related to the time position of the resources indicated in the auxiliary resource set. On the one hand, Pn can be the time domain position of the auxiliary resource indicated based on the resource combination, and on the other hand, it can also be the time domain position of the auxiliary resource set directly indicated in the auxiliary resource set.

[0172] In the embodiment of the present disclosure, the number of resource combinations is at most 2, and the number of resources indicated in each resource combination is at most 3.

[0173] In one implementation, in the method for communication based on an auxiliary resource set provided by an embodiment of the present disclosure, Pn is the time domain position of the nth resource in the mth resource combination indicated in the auxiliary resource set; wherein the value of n is a positive integer less than or equal to 3. When the control information is used to carry the auxiliary resource set, the value of m is a positive integer less than or equal to 2, and when the MAC CE is used to carry the auxiliary resource set, the value of m is ≤M, and M is determined according to the indication of the network device.

[0174] In the method for communication based on an auxiliary resource set provided by an embodiment of the present disclosure, when Pn is the time domain position of the resource in the second resource combination indicated in the auxiliary resource set, the probability that the auxiliary resource indicated in the auxiliary resource set is sent before the window end time domain position is high, that is, the probability of the existence of outdated resources is high, and the outdated resources are large. That is, the value of m is 2. When the auxiliary resource set is carried by MAC CE, m is M, and M is determined according to the network device indication.

[0175] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, Pn is the time domain position of the last resource in the resource combination indicated in the auxiliary resource set. That is, the value of n is 3. There is a high probability that the auxiliary resource indicated in the auxiliary resource set is sent before the window end time domain position, that is, there is a high probability that outdated resources exist, and there are many outdated resources.

[0176] In the method for communication based on the auxiliary resource set provided by the embodiment of the present disclosure, Pn is the time domain position of the third resource in the second resource combination indicated in the auxiliary resource set. That is, the value of m is 2, and the value of n is 3. The probability that the auxiliary resource indicated in the auxiliary resource set is sent before the window end time domain position is high, that is, the probability of the existence of outdated resources is high, and the outdated resources are large.

[0177] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the time domain position Pn corresponding to the resource indicated in the auxiliary resource set may be the time domain position of the auxiliary resource set directly indicated in the auxiliary resource set. For example, Pn is the time domain position of the xth resource indicated in the auxiliary resource set, such as when physical layer control signaling is used to carry auxiliary information, the value of x is a positive integer less than or equal to 6.

[0178] In one implementation, in the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, n is the time domain position of the last resource indicated in the auxiliary resource set. That is, the value of x is 6. There is a high probability that the auxiliary resource indicated in the auxiliary resource set is sent before the time domain position at the end of the window, that is, there is a high probability that outdated resources exist, and there are many outdated resources.

[0179] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, when the auxiliary resources indicated in the auxiliary resource set are sent before the window end domain position, that is, when there are outdated resources, the first user equipment can exclude the outdated resources and send the auxiliary resource set.

[0180] Fig. 9 is a flow chart of a method for communication based on an auxiliary resource set according to an exemplary embodiment. Fig. 9 As shown, the method for communicating based on the auxiliary resource set is used in a first user equipment, and includes the following steps.

[0181] In step S51, it is determined that the time domain position corresponding to the third time domain position reduced by the first time domain position offset is earlier than the window end time domain position.

[0182] The third time domain position is determined based on the time domain position corresponding to the resources indicated in the auxiliary resource set, and the first time domain position offset is determined based on the time when the second user equipment decodes the auxiliary resource set.

[0183] In one implementation, the third time domain position is the time domain position of the nth resource in the mth resource combination indicated in the auxiliary resource set; the value of n is a positive integer less than or equal to 3, when the control information is used to carry the auxiliary resource set, the value of m is a positive integer less than or equal to 2, when the MAC CE is used to carry the auxiliary resource set, the value of m is ≤M, and M is determined according to the indication of the network device.

[0184] In one implementation, when control information is used to carry the auxiliary resource set, the value of m is 2, and when MAC CE is used to carry the auxiliary resource set, m is M, which is determined according to the indication of the network device. The value of n is 3.

[0185] In one implementation, the third time domain position is the time domain position of the xth resource indicated in the auxiliary resource set. When the control information is used to carry the auxiliary resource set, the value of x is a positive integer less than or equal to 6.

[0186] In one implementation, the value of x is 6.

[0187] In step S52, the auxiliary resources of the auxiliary resource set at the time domain position after the second time domain position are sent, or sending the auxiliary resource set to the second user equipment within the resource selection window is abandoned.

[0188] In the embodiment of the present disclosure, sending the auxiliary resources of the auxiliary resource set at the time domain position after the second time domain position can be understood as excluding the auxiliary resources of the auxiliary resource set at the time domain position before the second time domain position, and sending the remaining auxiliary resources after excluding the obsolete resources.

[0189] In the embodiment of the present disclosure, when the auxiliary resources indicated in the auxiliary resource set are sent before the window end domain position, that is, when there are outdated resources, the first user equipment can exclude the outdated resources and send the auxiliary resource set, which can increase the possibility of the second user equipment using the auxiliary resources normally and improve the communication performance based on the auxiliary resource set.

[0190] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the time domain position at the end of the resource selection window for sending the auxiliary resource set is determined by specifying a time domain offset (a first time domain offset, a second time domain offset), so that the auxiliary resource set is sent before the window end time domain position, or auxiliary resources that are outdated before the window end time domain position are excluded, which can increase the possibility of the second user equipment using the auxiliary resources normally and improve the communication performance based on the auxiliary resource set.

[0191] Based on the same concept, an embodiment of the present disclosure also provides a method for communicating based on an auxiliary resource set, which is performed by a second user equipment.

[0192] Fig.10 is a flow chart of a method for communication based on an auxiliary resource set according to an exemplary embodiment. Fig.10 As shown, the method for communicating based on the auxiliary resource set is used in the second user equipment, and includes the following steps.

[0193] In step S61, a window end time domain position of a resource selection window is determined, the resource selection window is a time window in which the first user equipment sends a secondary resource set to the second user equipment, and the window end time domain position is determined based on a specified time domain position offset.

[0194] In step S62, a secondary resource set sent by a first user equipment is received based on the window end domain position.

[0195] In the method for performing resource selection based on an auxiliary resource set provided by an embodiment of the present disclosure, the second user equipment determines the window end domain position of the resource selection window based on a specified time domain position offset, and receives the auxiliary resource set sent by the first user equipment based on the window end domain position. This can improve the situation in which the auxiliary resources indicated in the auxiliary resource set are received after the window end domain position, causing the auxiliary resources to be outdated and unable to be used, thereby improving the communication performance based on the auxiliary resource set.

[0196] In one implementation, the window end time domain position is determined based on the first time domain position and the first time domain position offset, wherein the first time domain position is determined based on the time domain position corresponding to the resource indicated in the auxiliary resource set, and the first time domain position offset is determined based on the time when the second user equipment decodes the auxiliary resource set.

[0197] In one implementation, the window ends at a time domain position that is the first time domain position minus the time domain position corresponding to the first time domain position offset, i.e., n'+T2'=Pm-△T. Or the window ends at a time domain position that is earlier than the first time domain position minus the time domain position corresponding to the first time domain position offset, i.e., n'+T2'<Pm-△T.

[0198] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the first time domain position corresponding to the resources indicated in the auxiliary resource set can be, on the one hand, the time domain position of the auxiliary resource indicated based on the resource combination, and on the other hand, it can also be the time domain position of the auxiliary resource set directly indicated in the auxiliary resource set.

[0199] In the embodiment of the present disclosure, the number of resource combinations is at most 2, and the number of resources indicated in each resource combination is at most 3.

[0200] In one implementation, in the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the first time domain position is the time domain position of the nth resource in the mth resource combination indicated in the auxiliary resource set; the value of n is a positive integer less than or equal to 3, and when control information is used to carry the auxiliary resource set, the value of m is a positive integer less than or equal to 2, and when MAC CE is used to carry the auxiliary resource set, the value of m is ≤M, and M is determined according to an indication of the network device.

[0201] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, in order to reduce the probability of receiving the auxiliary resource indicated in the auxiliary resource set after the time domain position at the end of the window, the first time domain position is the time domain position of the resource in the first resource combination indicated in the auxiliary resource set. That is, the value of m is 1.

[0202] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, in order to reduce the probability of receiving the auxiliary resource indicated in the auxiliary resource set after the time domain position at the end of the window, the first time domain position is the time domain position of the first resource in the resource combination indicated in the auxiliary resource set. That is, the value of n is 1.

[0203] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, in order to reduce the probability of receiving the auxiliary resource indicated in the auxiliary resource set after the time domain position at the end of the window, the first time domain position is the time domain position of the first resource in the first resource combination indicated in the auxiliary resource set. That is, the value of m is 1, and the value of n is 1.

[0204] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the first time domain position corresponding to the time domain position of the resource indicated in the auxiliary resource set may be the time domain position of the auxiliary resource set directly indicated in the auxiliary resource set. For example, the first time domain position is the time domain position of the xth resource indicated in the auxiliary resource set, such as when physical layer control signaling is used to carry auxiliary information, the value of x is a positive integer less than or equal to 6.

[0205] In one implementation, in the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, in order to reduce the probability of receiving the auxiliary resource indicated in the auxiliary resource set after the time domain position at the end of the window, the first time domain position is the time domain position of the first resource indicated in the auxiliary resource set. That is, the value of x is 1.

[0206] In one implementation, in the method for communicating based on auxiliary resource sets provided by the embodiments of the present disclosure, when n'+T2'=Pm-ΔT, or n'+T2'<Pm-ΔT, the second user equipment receives the auxiliary resource set sent by the first user equipment within the resource selection window.

[0207] In one implementation, the first time domain position is reduced by the time domain position corresponding to the first time domain position offset, and the time domain position corresponding to the first specified time domain offset is increased earlier than the second time domain position, that is, Pm-△T<n'+value0. The second time domain position is the time domain position of the sending resource determined by the first user equipment to send the auxiliary resource set; the first specified time domain offset is a specified number of time unit values, or the first specified time domain offset is the minimum end time of the resource selection window, or the first specified time domain offset is the PDB value of the auxiliary resource set.

[0209] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the window end position of the resource selection window for sending the auxiliary resource set is before the time domain position of the auxiliary resources indicated by the auxiliary resource set. Therefore, when the second user equipment receives the auxiliary resource set sent by the first user equipment within the resource selection window, it can avoid receiving the auxiliary resources indicated in the auxiliary resource set after the window end time domain position.

[0210] In the method for communicating based on an auxiliary resource set provided by an embodiment of the present disclosure, the time domain position at the end of the window is determined based on the time domain position of the sending resource of the auxiliary resource set determined to be sent plus a specified time domain offset.
