[0036] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. For the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0037] The embodiments of the present application can be applied to any communication framework from a terminal device to a terminal device.

[0038] For example, vehicle-to-vehicle (V2V), vehicle-to-everything (V2X), device-to-device (D2D), etc.

[0039] Among them, the terminal in the embodiments of the present application can be any device or apparatus configured with a physical layer and a media access control layer. The terminal device can also be referred to as an access terminal. For example, a user equipment (UE), a user unit, a user station, a mobile station, a mobile device, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The access terminal can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device, or other linear processing devices connected to a wireless modem, a vehicle-mounted device, a wearable device, and so on. The embodiments of the present application are described by taking a vehicle-mounted terminal as an example, but are not limited thereto.

[0040] Optionally, in some embodiments of the present application, the embodiments of the present application can be applied to two transmission modes defined by the 3rd Generation Partnership Project (3GPP), which are respectively denoted as: Mode A and Mode B.

[0041] Figure 1 It is a schematic diagram of Mode A of the embodiments of the present application. Figure 2 It is a schematic diagram of Mode B of the embodiments of the present application.

[0042] InFigure 1 In the shown Mode A, the transmission resources of the vehicle-mounted terminals (vehicle-mounted terminal 121 and vehicle-mounted terminal 122) are allocated by the base station 110, and the vehicle-mounted terminals send data on the sidelink according to the resources allocated by the base station 110. Specifically, the base station 110 can allocate resources for single transmission to the terminal, or can also allocate semi-static transmission resources to the terminal.

[0043] In Figure 2 In the shown Mode B, the vehicle-mounted terminals (vehicle-mounted terminal 131 and vehicle-mounted terminal 132) adopt a transmission method of sensing plus reservation. The vehicle-mounted terminals independently select transmission resources on the sidelink resources for data transmission.

[0044] The following takes the vehicle-mounted terminal 131 as an example for specific illustration.

[0045] The vehicle-mounted terminal 131 obtains a set of available transmission resources by sensing in the resource pool, and the vehicle-mounted terminal 131 randomly selects a transmission resource from this set for data transmission.

[0046] Since the services in the vehicle networking system have periodic characteristics, in the embodiments of the present application, the vehicle-mounted terminal 131 can also adopt a semi-static transmission method. That is, after the vehicle-mounted terminal 131 obtains a transmission resource, it continuously uses this transmission resource in multiple transmission cycles to reduce the probability of resource reselection and resource conflict.

[0047] The vehicle-mounted terminal 131 can carry information for reserving the next transmission resource in the control information of this transmission, so that other terminals (for example, the vehicle-mounted terminal 132) can determine whether this resource is reserved and used by this user by detecting the control information of this user, so as to achieve the purpose of reducing resource conflict.

[0048] It should be noted that in the New Radio (NR) Vehicle to Everything (V2X), the user may be in a mixed mode, that is, the user can both use Mode A to obtain resources and at the same time use Mode B to obtain resources.

[0049] At the same time, in NR V2X, the system design requires the terminal device to perform continuous sending and receiving. However, when the terminal device performs continuous sending and receiving on the sidelink, in the case of reusing the sending / receiving capabilities of the sidelink and the uplink / downlink, it may cause conflicts between sidelink communication and paging reception in the idle state of the terminal device, and may also cause conflicts between sidelink communication and random access configuration, and may also cause conflicts between sidelink communication and downlink Discontinuous Reception (DRX) configuration.

[0050] Based on the above technical problems, the present application designs a wireless communication method, which can avoid conflicts between sidelink communication and cellular communication.

[0051] Figure 3 It is a schematic flowchart of the wireless communication method 200 according to an embodiment of the present application. The method 200 can be executed by a first terminal device. Figure 3 The first terminal device shown in Figure 1 or Figure 2 can be a vehicle-mounted terminal as shown.

[0052] As Figure 3 shown, the method 200 can include some or all of the following:

[0053] S210, the first terminal device receives first information sent by a second terminal device, where the first information is used to indicate a first resource and / or a second resource, the first resource is a resource used by the second terminal device for cellular communication, and the second resource is a resource used by the second terminal device for sidelink communication with a third terminal device;

[0054] S220, the first terminal device performs sidelink communication with the second terminal device on a resource other than the resource indicated by the first information.

[0055] It should be noted that the first terminal device performs sidelink communication with the second terminal device on a resource other than the resource indicated by the first information, so as to avoid conflicts between the sidelink communication between the first terminal device and the second terminal device and the cellular communication and / or sidelink communication performed by the second terminal device, which is beneficial to power saving of the second terminal device. Of course, in some cases, the sidelink communication between the first terminal device and the second terminal device may also occupy a part of the resources indicated by the first information. For example, in the case of less available resources, the sidelink communication between the first terminal device and the second terminal device may also occupy a part of the resources indicated by the first information. That is, the first terminal device tries to avoid performing sidelink communication with the second terminal device on the resources indicated by the first information.

[0056] That is, in the embodiment of the present application, the second terminal device can actively send the first information to the first terminal device, so that the first terminal device can learn the first resource and / or the second resource, so that when the first terminal device performs sidelink communication with the second terminal device, it can try to avoid this part of the resources indicated by the first information, thereby reducing the conflict between the sidelink communication between the first terminal device and the second terminal device and the cellular communication and / or sidelink communication performed by the second terminal device, which is beneficial to power saving of the second terminal device.

[0057] Optionally, in the embodiments of the present application, the first terminal device may also perform sidelink communication with the second terminal device on resources other than the third resource, where the third resource is the resource used by the first terminal device for sidelink communication with the fourth terminal device. That is, when the first terminal device performs sidelink communication with the second terminal device, it can also avoid the resource used by the first terminal device for sidelink communication with the fourth terminal device, thereby reducing the conflict between the sidelink communications of the first terminal device with different terminal devices and being beneficial to power saving of the first terminal device. Of course, in some cases, the sidelink communication between the first terminal device and the second terminal device may also occupy a part of the third resource. For example, when the available resources are scarce, the sidelink communication between the first terminal device and the second terminal device may also occupy a part of the third resource.

[0058] Optionally, in the embodiments of the present application, the first terminal device sends second information to the second terminal device, and the second information is used to indicate the resources for the second terminal device to perform sidelink communication with the first terminal device. That is, after receiving the first information, the first terminal device can also indicate the resources for the second terminal device to perform sidelink communication with the first terminal device, so that when the second terminal device performs sidelink communication with the first terminal device, it can try to avoid this part of the resources indicated by the first information, thereby reducing the conflict between the sidelink communication between the first terminal device and the second terminal device and the cellular communication and / or sidelink communication performed by the second terminal device.

[0059] Optionally, the resources indicated by the second information may be determined according to the resources (the first resource and / or the second resource) indicated by the first information.

[0060] Optionally, the resources indicated by the second information may also be determined according to the resources (the first resource and / or the second resource) indicated by the first information and the third resource.

[0061] Optionally, the resources indicated by the second information may be configured by a first network device serving the first terminal device.

[0062] Specifically, the first terminal device sends third information to the first network device, and the third information is used to indicate the resources indicated by the first information; the first terminal device receives fourth information sent by the first network device, and the fourth information is used to indicate the resource information for the first terminal device and / or the second terminal device to perform sidelink communication.

[0063] It should be noted that the first terminal device may determine the second information based on the fourth information. That is, the resource information for the sidelink communication indicated by the second information may be configured by the first network device.

[0064] Optionally, the fourth information is further used to indicate resource information for the first terminal device to perform downlink reception and / or uplink transmission.

[0065] Optionally, the resources indicated by the fourth information may be determined according to the resources indicated by the third information.

[0066] It should be noted that the embodiments of the present application can also be adapted to multicast communication. For example, a sidelink is established between the first terminal device and at least one terminal device.

[0067] For example, assume that sidelinks are established between UE 1 and UE 2, UE 3, and UE 4 respectively. UE 1 receives information 1 sent by UE 2, and the information 1 indicates resource 1 for UE 2 to perform cellular communication and resource 2 for UE 2 to perform sidelink communication with UE 2'; UE 1 receives information 2 sent by UE 3, and the information 2 indicates resource 3 for UE 3 to perform cellular communication and resource 4 for UE 3 to perform sidelink communication with UE 3'; UE 1 receives information 3 sent by UE 4, and the information 3 indicates resource 5 for UE 4 to perform cellular communication and resource 6 for UE 4 to perform sidelink communication with UE 4'. UE1 avoids performing sidelink communication with at least one of UE 2, UE 3, and UE 4 on the resources indicated by the information 1, the resources indicated by the information 2, and the resources indicated by the information 3.

[0068] Furthermore, UE 1 may also avoid performing sidelink communication with at least one of UE 2, UE 3, and UE 4 on resource 7, where resource 7 is the resource for UE 1 to perform sidelink communication with UE 1'.

[0069] Furthermore, UE 1 may also send information 4 to UE 2, where the information 4 is used to indicate the resources for UE 2 to perform sidelink communication with UE 1; UE 1 may also send information 5 to UE 3, where the information 5 is used to indicate the resources for UE 3 to perform sidelink communication with UE 1; UE 1 may also send information 6 to UE 4, where the information 6 is used to indicate the resources for UE 4 to perform sidelink communication with UE 1.

[0070] Optionally, the resources indicated by the information 4, the resources indicated by the information 5, or the resources indicated by the information 6 may be configured by a network device serving UE 1.

[0071] Optionally, in the embodiments of the present application, the first terminal device is used to perform sidelink communication with the second terminal device on a first time-domain resource, and the first terminal device is used to perform cellular communication with the first network device on a second time-domain resource.

[0072] It should be noted that the first time-domain resource should avoid overlapping with the second time-domain resource in the time domain, so as to avoid conflicts between the cellular communication between the first terminal device and the first network device and the sidelink communication between the first terminal device and the second terminal device caused by resource selection as much as possible.

[0073] Optionally, as an example, the first time-domain resource may include some or all of the resources indicated by the first information, and the second time-domain resource may also include some or all of the resources indicated by the first information. However, after obtaining the resources indicated by the first information, the first terminal device performs sidelink communication with the second terminal device on the resources other than the resources indicated by the first information in the first time-domain resource, so as to avoid conflicts between the sidelink communication between the first terminal device and the second terminal device and the cellular communication and / or sidelink communication performed by the second terminal device, and further achieve power saving of the first terminal device and the second terminal device.

[0074] Optionally, as another example, the first time-domain resource does not include the resources indicated by the first information, and the first terminal device performs sidelink communication with the second terminal device on the first time-domain resource. That is, the first terminal device performs sidelink communication with the second terminal device on the first time-domain resource, which can avoid conflicts between the sidelink communication between the first terminal device and the second terminal device and the cellular communication and / or sidelink communication performed by the second terminal device, and further achieve power saving of the first terminal device and the second terminal device.

[0075] It should be noted that the second terminal device may perform sidelink communication with the first terminal device on the first time-domain resource, and the second terminal device may perform cellular communication with the second network device on the second time-domain resource, or may perform cellular communication with the second network device on other resources except the second time-domain resource.

[0076] Optionally, the first time-domain resource and / or the second time-domain resource are non-continuous resources in the time domain. That is, the first terminal device may perform discontinuous sidelink communication with the second terminal device on the first time-domain resource, and the first terminal device may simultaneously perform discontinuous cellular communication with the first network device on the second time-domain resource.

[0077] Optionally, in the embodiments of the present application, the first time-domain resource satisfies at least one of the following conditions:

[0078] The first time-domain resource is limited to be used by the first logical channel or logical channel group on the sidelink between the first terminal device and the second terminal device;

[0079] The first time-domain resource is limited to be used in the first propagation mode;

[0080] The first time-domain resource is limited to be used when the sidelink between the first terminal device and the second terminal device is not established;

[0081] The first time-domain resource is limited to be used when the sidelink between the first terminal device and the second terminal device is established.

[0082] Optionally, the first logical channel or logical channel group is a logical channel or logical channel group carrying signaling, or the first logical channel or logical channel group is a logical channel or logical channel group carrying data.

[0083] Optionally, the signaling is sidelink Radio Resource Control (RRC) signaling, or sidelink PC5 signaling (PC5-S).

[0084] For example, when the sidelink between the first terminal device and the second terminal device is not established, the first logical channel or logical channel group is a logical channel or logical channel group carrying signaling.

[0085] For another example, when the sidelink between the first terminal device and the second terminal device is established, the first logical channel or logical channel group is a logical channel or logical channel group carrying data.

[0086] Optionally, the first propagation mode is broadcast, or the first propagation mode is unicast or multicast.

[0087] For example, when the sidelink between the first terminal device and the second terminal device is not established, the first propagation mode is broadcast.

[0088] For another example, when the sidelink between the first terminal device and the second terminal device is established, the first propagation mode is unicast or multicast.

[0089] Optionally, in the embodiments of the present application, the second time-domain resource is used to receive a downlink paging message, and / or the second time-domain resource is used to send an uplink random access message.

[0090] Optionally, in the embodiments of the present application, the first time-domain resource and the second time-domain resource may be configured by the network device through a system message, or may be configured by the network device through a downlink signaling.

[0091] For example, the first terminal device receives a first system message broadcast by the first network device. The first system message includes first indication information and second indication information. The first indication information is used to indicate the first time-domain resource, and the second indication information is used to indicate the second time-domain resource.

[0092] For another example, the first terminal device receives a first system message and a second system message broadcast by the first network device. The first system message includes first indication information, and the second system message includes second indication information. The first indication information is used to indicate the first time-domain resource, and the second indication information is used to indicate the second time-domain resource.

[0093] For yet another example, the first terminal device receives a first downlink signaling sent by the first network device. The first downlink signaling includes first indication information and second indication information. The first indication information is used to indicate the first time-domain resource, and the second indication information is used to indicate the second time-domain resource.

[0094] The first downlink signaling may be an RRC signaling, for example.

[0095] It should be noted that if the first terminal device is in the idle state, that is, the uplink and downlink links between the first terminal device and the first network device are not established, the first network device may configure the first time-domain resource and the second time-domain resource by means of broadcasting. If the first terminal device is in the connected state, that is, the uplink and downlink links between the first terminal device and the first network device are established, the first network device may configure the first time-domain resource and the second time-domain resource by means of broadcasting or sending downlink signaling.

[0096] Therefore, in the embodiments of the present application, the first terminal device learns the resources used by the second terminal device for cellular communication, and / or learns the resources used by the second terminal device for sidelink communication with the third terminal device, and the first terminal device avoids performing sidelink communication with the second terminal device on these resources, thereby reducing the conflict between the sidelink communication between the first terminal device and the second terminal device and the cellular communication and / or sidelink communication performed by the second terminal device, and further facilitating power saving of the second terminal device.

[0097] Figure 4 It is a schematic flowchart of a wireless communication method 300 according to an embodiment of the present application. The method 300 may be executed by a first terminal device. Figure 4 The first terminal device shown in Figure 1 or Figure 2 may be a vehicle-mounted terminal as shown.

[0098] As Figure 4 shown, the method 300 may include some or all of the following:

[0099] S310. When a conflict occurs between the sidelink communication between the first terminal device and the second terminal device and the cellular communication between the first terminal device and the first network device, the first terminal device communicates according to a first priority order, where the first priority order is determined according to service attributes and / or resource attributes.

[0100] It should be noted that the first network device is a network device serving the first terminal device.

[0101] For example, in the first priority order, the priorities from high to low are A, E, B, C, F, D in sequence, where E and F are cellular communication services, and A, B, C, and D are sidelink communication services. That is to say, by communicating according to the first priority order, services can be flexibly selected for transmission based on service attributes, so that discontinuous transmission can be performed on the sidelink and the uplink / downlink, which is conducive to power saving of the first terminal device.

[0102] Optionally, in the embodiments of the present application, the situation where a conflict occurs between the sidelink communication between the first terminal device and the second terminal device and the cellular communication between the first terminal device and the first network device includes:

[0103] A conflict between sidelink reception and downlink reception, and / or a conflict between sidelink transmission and uplink transmission, and / or a conflict between sidelink reception and uplink transmission.

[0104] For example, a conflict between sidelink reception and downlink reception in the case where the sidelink and the uplink / downlink reuse the reception capability.

[0105] For another example, a conflict between sidelink transmission and uplink transmission in the case where the sidelink and the uplink / downlink reuse the transmission capability.

[0106] Optionally, the sidelink between the first terminal device and the second terminal device may be a unicast link, and the sidelink between the first terminal device and the second terminal device may also be a link in a multicast link.

[0107] Optionally, in the embodiments of the present application, the first priority order is pre-configured by the first network device, or the first priority order is preset, or the first priority order is agreed upon by the protocol.

[0108] Optionally, in the embodiments of the present application, the first terminal device is used to perform the sidelink communication with the second terminal device on a first time-domain resource, and the first terminal device is used to perform the cellular communication with the first network device on a second time-domain resource.

[0109] It should be noted that the second terminal device can perform sidelink communication with the first terminal device on the first time-domain resource. The second terminal device can perform cellular communication with the second network device on the second time-domain resource, or can also perform cellular communication with the second network device on other resources except the second time-domain resource.

[0110] Optionally, the first time-domain resource and / or the second time-domain resource are discontinuous resources in the time domain. That is, the first terminal device can perform discontinuous sidelink communication with the second terminal device on the first time-domain resource, and at the same time, the first terminal device can perform discontinuous cellular communication with the first network device on the second time-domain resource.

[0111] Optionally, in the embodiments of the present application, the first time-domain resource satisfies at least one of the following conditions:

[0112] The first time-domain resource is limited to be used by the first logical channel or logical channel group on the sidelink between the first terminal device and the second terminal device;

[0113] The first time-domain resource is limited to be used in a first propagation mode;

[0114] The first time-domain resource is limited to be used when the sidelink between the first terminal device and the second terminal device is not established;

[0115] The first time-domain resource is limited to be used when the sidelink between the first terminal device and the second terminal device is established.

[0116] Optionally, the first logical channel or logical channel group is a logical channel or logical channel group carrying signaling, or the first logical channel or logical channel group is a logical channel or logical channel group carrying data.

[0117] Optionally, the signaling is sidelink RRC signaling, or sidelink PC5 signaling (PC5 signal, PC5-S).

[0118] For example, when the sidelink between the first terminal device and the second terminal device is not established, the first logical channel or logical channel group is a logical channel or logical channel group carrying signaling.

[0119] For another example, when the sidelink between the first terminal device and the second terminal device is established, the first logical channel or logical channel group is a logical channel or logical channel group carrying data.

[0120] Optionally, the first propagation mode is broadcast, or the first propagation mode is unicast or multicast.

[0121] For example, when the sidelink between the first terminal device and the second terminal device is not established, the first propagation mode is broadcast.

[0122] For another example, when the sidelink between the first terminal device and the second terminal device is established, the first propagation mode is unicast or multicast.

[0123] Optionally, in the embodiments of the present application, the second time-domain resource is used for receiving a downlink paging message, and / or the second time-domain resource is used for sending an uplink random access message.

[0124] Optionally, in the embodiments of the present application, the first time-domain resource and the second time-domain resource may be configured by the network device through a system message, or may be configured by the network device through a downlink signaling.

[0125] For example, the first terminal device receives a first system message broadcast by the first network device, and the first system message includes first indication information and second indication information, where the first indication information is used to indicate the first time-domain resource, and the second indication information is used to indicate the second time-domain resource.

[0126] For another example, the first terminal device receives a first system message and a second system message broadcast by the first network device, the first system message includes first indication information, and the second system message includes second indication information, where the first indication information is used to indicate the first time-domain resource, and the second indication information is used to indicate the second time-domain resource.

[0127] For still another example, the first terminal device receives a first downlink signaling sent by the first network device, and the first downlink signaling includes first indication information and second indication information, where the first indication information is used to indicate the first time-domain resource, and the second indication information is used to indicate the second time-domain resource.

[0128] The first downlink signaling may be an RRC signaling, for example.

[0129] It should be noted that if the first terminal device is in the idle state, that is, the uplink and downlink links between the first terminal device and the first network device are not established, the first network device may configure the first time-domain resource and the second time-domain resource by broadcasting. If the first terminal device is in the connected state, that is, the uplink and downlink links between the first terminal device and the first network device are established, the first network device may configure the first time-domain resource and the second time-domain resource by broadcasting or sending downlink signaling.

[0130] Optionally, as an example 1, the first terminal device receives the first information sent by the second terminal device. The first information is used to indicate the first resource and / or the second resource. The first resource is the resource used by the second terminal device for cellular communication, and the second resource is the resource used by the second terminal device for sidelink communication with a third terminal device. The first terminal device performs sidelink communication with the second terminal device on a resource other than the resource indicated by the first information.

[0131] That is, the second terminal device can send the resource information used for its cellular communication and / or sidelink communication to the first terminal device, so that when the first terminal device performs sidelink communication with the second terminal device, this part of the resources can be avoided, thereby reducing the conflict between the sidelink communication between the first terminal device and the second terminal device and the cellular communication and / or sidelink communication performed by the second terminal device, and further achieving power saving of the first terminal device and the second terminal device.

[0132] Further, in example 1, the first terminal device sends the second information to the second terminal device. The second information is used to indicate the resource information for the second terminal device to perform sidelink communication with the first terminal device. That is, after receiving the first information, the first terminal device can also indicate the resource information for the second terminal device to perform sidelink communication with the first terminal device, so that when the second terminal device performs sidelink communication with the first terminal device, this part of the resources can be avoided as much as possible, thereby reducing the conflict between the sidelink communication between the first terminal device and the second terminal device and the cellular communication and / or sidelink communication performed by the second terminal device, and further achieving power saving of the first terminal device and the second terminal device.

[0133] Optionally, the resource information of the sidelink communication indicated by the second information can be determined according to the resource information of the cellular communication indicated by the first information.

[0134] Furthermore, in example 1, the resource information of the sidelink communication indicated by the second information is configured by the first network device.

[0135] Specifically, the first terminal device sends the third information to the first network device. The third information is used to indicate the resources indicated by the first information. The first terminal device receives the fourth information sent by the first network device. The fourth information is used to indicate the resource information for the first terminal device and / or the second terminal device to perform sidelink communication.

[0136] It should be noted that the first terminal device can determine the second information based on the fourth information. That is, the resources of the sidelink communication indicated by the second information can be configured by the first network device.

[0137] Optionally, the fourth information is further used to indicate resource information for the first terminal device to perform downlink reception and / or uplink transmission.

[0138] Optionally, the resource information of the sidelink communication indicated by the fourth information may be determined according to the resources indicated by the third information.

[0139] Optionally, as Example 2, if a sidelink is established between the first terminal device and at least one terminal device, the at least one terminal device includes the second terminal device, and the first terminal device receives at least one first information respectively sent by the at least one terminal device, the at least one first information is used to indicate resources for the at least one terminal device corresponding to the at least one first information to perform cellular communication; the first terminal device performs sidelink communication with the at least one terminal device on resources other than the resources indicated by the at least one first information.

[0140] That is, Example 2 is the multicast communication between the first terminal device and at least one terminal device.

[0141] Further, in Example 2, the first terminal device sends at least one second information to the at least one terminal device respectively, and the at least one second information is used to indicate resource information for the at least one terminal device to perform sidelink communication with the first terminal device.

[0142] Furthermore, in Example 2, the first terminal device sends fifth information to the first network device, and the fifth information is used to indicate the resources indicated by the at least one first information; the first terminal device receives sixth information sent by the first network device, and the sixth information is used to indicate resource information for the at least one terminal device to perform sidelink communication with the first terminal device.

[0143] Optionally, the sixth information is further used to indicate resource information for the first terminal device to perform downlink reception and / or uplink transmission.

[0144] The solutions in the wireless communication method 200 are described in detail below with reference to Embodiment 1 to Embodiment 4.

[0145] Embodiment 1, as Figure 5As shown in the figure, UE 1 may be the first terminal device mentioned above, Network (NW) 1 may be the first network device mentioned above, UE 2 may be the second terminal device mentioned above, and NW 2 may be the second network device mentioned above. UE 1 is in the RRC idle state, that is, the cellular network between UE 1 and NW 1 is not established, and the sidelink between UE 1 and UE 2 is not established either. UE 1 can obtain the first time-domain resource and the second time-domain resource by receiving the System Information Block (SIB) broadcast by NW 1. UE 1 can perform sidelink communication with UE 2 on the first time-domain resource, and UE 1 can perform cellular communication with NW 1 on the second time-domain resource. When the sidelink communication of UE 1 conflicts with the cellular communication, UE 1 can communicate based on the first priority order.

[0146] It should be noted that in the first embodiment, UE 2 can also perform operations similar to those of UE 1, so that when the sidelink communication of UE 2 conflicts with the cellular communication, UE 2 can communicate based on the first priority order.

[0147] Embodiment 2, as Figure 6 As shown in the figure, UE 1 may be the first terminal device mentioned above, NW 1 may be the first network device mentioned above, UE 2 may be the second terminal device mentioned above, and NW 2 may be the second network device mentioned above. UE 1 is in the RRC idle state, that is, the cellular network between UE 1 and NW 1 is not established, and the sidelink between UE 1 and UE 2 is already established. UE 1 can obtain the first time-domain resource and the second time-domain resource by receiving the SIB broadcast by NW 1. UE 1 can perform sidelink communication with UE 2 on the first time-domain resource, and UE 1 can perform cellular communication with NW 1 on the second time-domain resource. UE 1 receives the first information sent by UE 2, and this first information is used to indicate the resource information of UE 2 for cellular communication; and UE 1 sends the second information to UE 2, and this second information is used to indicate the resource information for UE 2 to perform sidelink communication with UE 1. When the sidelink communication of UE 1 conflicts with the cellular communication, UE 1 can communicate based on the first priority order.

[0148] It should be noted that if UE 1 is a sending device and UE 2 is a receiving device, the first information is specifically used to indicate resource-related information for UE 2 to perform downlink reception and / or uplink transmission. For example, resource information for downlink paging reception, or resource information for uplink random access transmission. The second information is specifically used to indicate resource-related information for UE 2 to perform sidelink reception with UE 1. If UE 1 is a receiving device and UE 2 is a sending device, the first information is specifically used to indicate resource-related information for UE 2 to perform uplink transmission, such as resource information for uplink random access transmission. The second information is specifically used to indicate resource-related information for UE 2 to perform sidelink transmission with UE 1.

[0149] It should be noted that in Embodiment 2, UE 2 can also perform operations similar to those of UE 1, so that when there is a conflict between the sidelink communication and the cellular communication of UE 2, UE 2 can communicate based on the first priority order.

[0150] Embodiment 3, as Figure 7 shown, UE 1 can be the above-mentioned first terminal device, NW 1 can be the above-mentioned first network device, UE 2 can be the above-mentioned second terminal device, and NW 2 can be the above-mentioned second network device. UE 1 is in the RRC connected state, that is, the cellular network between UE 1 and NW 1 has been established, and the sidelink between UE 1 and UE 2 has not been established. UE 1 can obtain the first time-domain resource and the second time-domain resource by receiving the RRC signaling sent by NW 1. UE 1 can perform sidelink communication with UE 2 on the first time-domain resource, and UE 1 can perform cellular communication with NW 1 on the second time-domain resource. When there is a conflict between the sidelink communication and the cellular communication of UE 1, UE 1 can communicate based on the first priority order.

[0151] It should be noted that in Embodiment 3, UE 2 can also perform operations similar to those of UE 1, so that when there is a conflict between the sidelink communication and the cellular communication of UE 2, UE 2 can communicate based on the first priority order.

[0152] Embodiment 4, as Figure 8As shown, UE 1 may be the first terminal device mentioned above, NW 1 may be the first network device mentioned above, UE 2 may be the second terminal device mentioned above, and NW 2 may be the second network device mentioned above. UE 1 is in the RRC connected state, that is, the cellular network between UE 1 and NW 1 has been established, and the sidelink between UE 1 and UE 2 has been established. UE 1 can obtain the first time-domain resource and the second time-domain resource by receiving the RRC signaling sent by NW 1. UE 1 can perform sidelink communication with UE 2 on the first time-domain resource, and UE 1 can perform cellular communication with NW 1 on the second time-domain resource. UE 1 receives the first information sent by UE 2, and this first information is used to indicate the resource information used by UE 2 for cellular communication; UE 1 sends the third information to NW 1, and this third information is used to indicate the resource information used by the second terminal device for cellular communication; UE 1 receives the fourth information sent by NW 1, and this fourth information is used to indicate the resource information used by UE 1 and / or UE 2 for sidelink communication; and UE 1 sends the second information to UE 2, and this second information is used to indicate the resource information for UE 2 to perform sidelink communication with UE 1. When a conflict occurs between the sidelink communication and the cellular communication of UE 1, UE 1 can communicate based on the first priority order.

[0153] Optionally, this fourth information is further used to indicate the resource information for UE 1 to perform downlink reception and / or uplink transmission.

[0154] It should be noted that if UE 1 is a transmitting device and UE 2 is a receiving device, this first information and this third information are specifically used to indicate the resource-related information for UE 2 to perform downlink reception and / or uplink transmission. For example, the resource information for downlink paging reception, or for example, the resource information for uplink random access transmission; this second information is specifically used to indicate the resource-related information for UE 2 to perform sidelink reception with UE 1. If UE 1 is a receiving device and UE 2 is a transmitting device, this first information and this third information are specifically used to indicate the resource-related information for UE 2 to perform uplink transmission. For example, the resource information for uplink random access transmission; this second information is specifically used to indicate the resource-related information for UE 2 to perform sidelink transmission with UE 1.

[0155] It should be noted that in the fourth embodiment, UE 2 can also perform operations similar to those of UE 1, so that when a conflict occurs between the sidelink communication and the cellular communication of UE 2, UE 2 can communicate based on the first priority order.

[0156] The scenario described in the above second embodiment or the fourth embodiment is for unicast, and it is also applicable to the multicast scenario. Specifically,

[0157] A sidelink is established between UE 1 and at least one terminal device, where the at least one terminal device includes UE 2. UE 1 receives at least one first piece of information respectively sent by the at least one terminal device, and the at least one first piece of information is used to indicate resource information for the at least one terminal device corresponding to the at least one first piece of information to perform cellular communication; UE 1 sends fifth information to NW 1, and the fifth information is used to indicate resource information for the at least one terminal device to perform cellular communication; UE 1 receives sixth information sent by NW 1, and the sixth information is used to indicate resource information for the at least one terminal device to perform sidelink communication with UE 1; UE 1 sends at least one second piece of information to the at least one terminal device respectively, and the at least one second piece of information is used to indicate resource information for the at least one terminal device to perform sidelink communication with UE 1. When a conflict occurs between the sidelink communication and the cellular communication of UE 1, UE 1 can communicate based on the first priority order. Of course, UE 2 can also perform operations similar to those of UE 1, so that when a conflict occurs between the sidelink communication and the cellular communication of UE 2, UE 2 can communicate based on the first priority order.

[0158] Therefore, in the embodiments of the present application, in the case where a conflict occurs between the sidelink communication between the first terminal device and the second terminal device and the cellular communication between the first terminal device and the first network device, the first terminal device communicates according to the first priority order. Since the first priority order is determined according to the service attributes, the first terminal device can flexibly select services for transmission based on the service attributes, so that discontinuous transmission can be performed on the sidelink and the uplink / downlink, which is beneficial to the first terminal device to achieve power saving.

[0159] It should be understood that the relevant descriptions in the wireless communication method 200 and the wireless communication method 300 in the embodiments of the present application can be referred to each other.
