[0035] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. For the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The embodiments of the present application may be applicable to any terminal device to terminal device communication framework.

[0037] For example, vehicle to vehicle (V2V), vehicle to everything (V2X), device to device (D2D), etc.

[0038] Among them, the terminal in the embodiment of the present application can be any device or apparatus configured with a physical layer and a media access control layer, and the terminal device can also be called an access terminal. For example, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or 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 function, a computing device or other linear processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, etc. The embodiment of the present application is described by taking a vehicle-mounted terminal as an example, but is not limited to this.

[0039] Optionally, in some embodiments of the present application, the embodiments of the present application may be applicable to the 3rd Generation Partnership Project (3GPP) which defines two transmission modes, which are respectively denoted as: mode A and mode B.

[0040] Figure 1 It is a schematic diagram of mode A of an embodiment of the present application. Figure 2 It is a schematic diagram of mode B of an embodiment of the present application.

[0041] exist Figure 1 In the illustrated mode A, the transmission resources of the vehicle terminals (vehicle terminals 121 and vehicle terminals 122) are allocated by the base station 110, and the vehicle terminals transmit data on the sidelink according to the resources allocated by the base station 110. Specifically, the base station 110 may allocate resources for a single transmission to the terminal, or may allocate resources for a semi-static transmission to the terminal.

[0042] exist Figure 2 In the illustrated mode B, the vehicle-mounted terminals (vehicle-mounted terminal 131 and vehicle-mounted terminal 132) adopt a transmission mode of sensing and reservation, and the vehicle-mounted terminals autonomously select transmission resources on the side link resources for data transmission.

[0043] The following is a specific description using the vehicle-mounted terminal 131 as an example.

[0044] The vehicle-mounted terminal 131 obtains a set of available transmission resources in the resource pool by listening, and the vehicle-mounted terminal 131 randomly selects a transmission resource from the set to transmit data.

[0045] Since the services in the Internet of Vehicles system have periodic characteristics, in the embodiment of the present application, the vehicle terminal 131 can also adopt a semi-static transmission mode. That is, after the vehicle terminal 131 obtains a transmission resource, it continues to use the transmission resource in multiple transmission cycles to reduce the probability of resource reselection and resource conflict.

[0046] The vehicle terminal 131 can carry information about the resources reserved for the next transmission in the control information of this transmission, so that other terminals (for example, the vehicle terminal 132) can determine whether this resource is reserved and used by the user by detecting the control information of the user, thereby reducing resource conflicts.

[0047] 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 use mode A to acquire resources and mode B to acquire resources at the same time.

[0048] At the same time, in NR V2X, the system design requires the terminal device to perform continuous transmission and reception. However, when the terminal device performs continuous transmission and reception on the sidelink, in the case where the sidelink and uplink and downlink reuse the transmission / reception capabilities, it may cause a conflict between the sidelink communication and the terminal device's idle state paging reception, and may also cause a conflict between the sidelink communication and the random access configuration, and may also cause a conflict between the sidelink communication and the downlink discontinuous reception (DRX) configuration.

[0049] Based on the above technical problems, the present application designs a wireless communication method that can avoid the conflict between sideline communication and cellular communication.

[0050] Figure 3 2 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application. The method 200 may be executed by a first terminal device. Figure 3 The first terminal device shown in FIG. 1 may be as follows: Figure 1 or Figure 2 The vehicle terminal shown.

[0051] like Figure 3 As shown, the method 200 may include part or all of the following contents:

[0052] S210, the first terminal device receives first information sent by the second terminal device, wherein 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 sideline communication with a third terminal device;

[0053] S220, the first terminal device performs side communication with the second terminal device on resources other than the resources indicated by the first information.

[0054] It should be noted that the first terminal device performs side communication with the second terminal device on resources other than the resources indicated by the first information, thereby avoiding conflicts between the side communication between the first terminal device and the second terminal device and the cellular communication and / or side communication performed by the second terminal device, which is beneficial to power saving of the second terminal device. Of course, in some cases, the side 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, when there are fewer available resources, the side 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 side communication with the second terminal device on the resources indicated by the first information.

[0055] That is, in an 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 obtain the first resource and / or the second resource, so that when the first terminal device and the second terminal device perform side communication, they can try to avoid the part of the resources indicated by the first information, thereby reducing the conflict between the side communication between the first terminal device and the second terminal device and the cellular communication and / or side communication performed by the second terminal device, which is beneficial to saving power for the second terminal device.

[0056] Optionally, in an embodiment of the present application, the first terminal device may also perform side communication with the second terminal device on a resource other than a third resource, and the third resource is a resource used by the first terminal device for side communication with a fourth terminal device. That is, when the first terminal device performs side communication with the second terminal device, the resource used by the first terminal device for side communication with the fourth terminal device may be avoided, thereby reducing the conflict between the side communication between the first terminal device and different terminal devices, which is beneficial to power saving of the first terminal device. Of course, in some cases, the side communication between the first terminal device and the second terminal device may also occupy a portion of the third resource. For example, when there are fewer available resources, the side communication between the first terminal device and the second terminal device may also occupy a portion of the third resource.

[0057] Optionally, in an embodiment 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 sideline communication between the second terminal device and the first terminal device. That is, after receiving the first information, the first terminal device may also indicate the resources for the sideline communication between the second terminal device and the first terminal device, so that when the second terminal device and the first terminal device perform sideline communication, the resources indicated by the first information can be avoided as much as possible, thereby reducing the conflict between the sideline communication between the first terminal device and the second terminal device and the cellular communication and / or sideline communication performed by the second terminal device.

[0058] Optionally, the resource indicated by the second information may be determined according to the resource indicated by the first information (the first resource and / or the second resource).

[0059] Optionally, the resource indicated by the second information may also be determined based on the resource indicated by the first information (the first resource and / or the second resource) and the third resource.

[0060] Optionally, the resources indicated by the second information may be configured for a first network device serving the first terminal device.

[0061] 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 resource information used by the first terminal device and / or the second terminal device for side communication.

[0062] It should be noted that the first terminal device may determine the second information based on the fourth information. That is, the resource information of the sideline communication indicated by the second information may be configured by the first network device.

[0063] Optionally, the fourth information is also used to indicate resource information used by the first terminal device for downlink reception and / or uplink transmission.

[0064] Optionally, the resources indicated by the fourth information may be determined based on the resources indicated by the third information.

[0065] It should be noted that the embodiments of the present application can also be adapted to multicast communications, for example, a side link is established between the first terminal device and at least one terminal device.

[0066] For example, it is assumed that UE 1 establishes sidelinks with UE 2, UE 3, and UE 4, respectively. UE 1 receives information 1 sent by UE 2, where the information 1 indicates resource 1 used by UE 2 for cellular communication and resource 2 used by UE 2 for sidelink communication with UE 2'; UE 1 receives information 2 sent by UE 3, where the information 2 indicates resource 3 used by UE 3 for cellular communication and resource 4 used by UE 3 for sidelink communication with UE 3'; UE 1 receives information 3 sent by UE 4, where the information 3 indicates resource 5 used by UE 4 for cellular communication and resource 6 used by UE 4 for sidelink communication with UE 4'. UE 1 avoids 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.

[0067] Furthermore, UE 1 may also avoid performing sideline communication with at least one UE among UE 2, UE 3 and UE 4 on resource 7, where resource 7 is a resource used by UE 1 for performing sideline communication with UE 1'.

[0068] Furthermore, UE 1 may also send information 4 to UE 2, where information 4 is used to indicate the resources for side communication between UE 2 and UE 1; UE 1 may also send information 5 to UE 3, where information 5 is used to indicate the resources for side communication between UE 3 and UE 1; UE 1 may also send information 6 to UE 4, where information 6 is used to indicate the resources for side communication between UE 4 and UE 1.

[0069] 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.

[0070] Optionally, in an embodiment of the present application, the first terminal device is used for sideline communication with the second terminal device on a first time domain resource, and the first terminal device is used for cellular communication with the first network device on a second time domain resource.

[0071] 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 minimize the conflict between the cellular communication between the first terminal device and the first network device and the side communication between the first terminal device and the second terminal device caused by resource selection.

[0072] Optionally, as an example, the first time domain resources may include part or all of the resources indicated by the first information, and the second time domain resources may also include part or all of the resources indicated by the first information. However, after acquiring the resources indicated by the first information, the first terminal device performs side communication with the second terminal device on the resources in the first time domain resources other than the resources indicated by the first information, thereby avoiding conflict between the side communication between the first terminal device and the second terminal device and the cellular communication and / or side communication performed by the second terminal device, thereby achieving power saving for the first terminal device and the second terminal device.

[0073] Optionally, as another example, the first time domain resource does not include the resource indicated by the first information, and the first terminal device performs sideline communication with the second terminal device on the first time domain resource. That is, the first terminal device performs sideline communication with the second terminal device on the first time domain resource, thereby avoiding the conflict between the sideline communication between the first terminal device and the second terminal device and the cellular communication and / or sideline communication performed by the second terminal device, thereby achieving power saving of the first terminal device and the second terminal device.

[0074] It should be noted that the second terminal device can communicate with the first terminal device sideways on the first time domain resources, the second terminal device can communicate with the second network device cellularly on the second time domain resources, and can also communicate with the second network device cellularly on resources other than the second time domain resources.

[0075] 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 can perform non-continuous sideline communication with the second terminal device on the first time domain resource, and the first terminal device can also perform non-continuous cellular communication with the first network device on the second time domain resource.

[0076] Optionally, in this embodiment of the present application, the first time domain resource satisfies at least one of the following conditions:

[0077] The first time domain resource is limited to the first logical channel or logical channel group on the side link between the first terminal device and the second terminal device;

[0078] The first time domain resource is limited to use in the first propagation mode;

[0079] The first time domain resource is limited to use when a side link between the first terminal device and the second terminal device is not established;

[0080] The first time domain resource is limited to use when a side link between the first terminal device and the second terminal device has been established.

[0081] Optionally, the first logical channel or logical channel group is a logical channel or logical channel group that carries signaling, or the first logical channel or logical channel group is a logical channel or logical channel group that carries data.

[0082] Optionally, the signaling is sidelink radio resource control (Radio Resource Control, RRC) signaling, or sidelink PC5 signaling (PC5 signal, PC5-S).

[0083] For example, when a side link 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 that carries signaling.

[0084] For another example, when a side link between the first terminal device and the second terminal device has been established, the first logical channel or logical channel group is a logical channel or logical channel group that carries data.

[0085] Optionally, the first propagation mode is broadcast, or the first propagation mode is unicast or multicast.

[0086] For example, when the side link between the first terminal device and the second terminal device is not established, the first propagation mode is broadcast.

[0087] For another example, when a side link between the first terminal device and the second terminal device has been established, the first propagation mode is unicast or multicast.

[0088] Optionally, in an embodiment 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.

[0089] Optionally, in an embodiment 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 downlink signaling.

[0090] 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, wherein 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.

[0091] 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, wherein 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 downlink signaling sent by the first network device, and the first downlink signaling includes first indication information and second indication information, wherein 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] The first downlink signaling may be, for example, RRC signaling.

[0094] It should be noted that if the first terminal device is in an idle state, that is, the uplink and downlink between the first terminal device and the first network device are not established, the first network device can configure the first time domain resource and the second time domain resource by broadcasting. If the first terminal device is in a connected state, that is, the uplink and downlink between the first terminal device and the first network device are established, the first network device can configure the first time domain resource and the second time domain resource by broadcasting or sending downlink signaling.

[0095] Therefore, in an embodiment of the present application, the first terminal device obtains resources used by the second terminal device for cellular communication, and / or obtains resources used by the second terminal device for sideline communication with a third terminal device, and the first terminal device avoids sideline communication with the second terminal device on these resources, thereby reducing the conflict between the sideline communication between the first terminal device and the second terminal device and the cellular communication and / or sideline communication performed by the second terminal device, which is beneficial for the second terminal device to save power.

[0096] Figure 4 3 is a schematic flow chart 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.

[0099] It should be noted that the first network device is a network device serving the first terminal device.

[0100] For example, the priorities in the first priority sequence are A, E, B, C, F, and D from high to low, where E and F are cellular communication services, and A, B, C, and D are sidelink communication services. In other words, based on the first priority sequence for communication, services can be flexibly selected for transmission based on service attributes, so that discontinuous transmission can be performed on the sidelink and uplink and downlink, which is beneficial for the first terminal device to achieve power saving.

[0101] Optionally, in the embodiment of the present application, the situation where the sideline communication between the first terminal device and the second terminal device conflicts with the cellular communication between the first terminal device and the first network device includes:

[0102] Conflict between sideline reception and downlink reception, and / or conflict between sideline transmission and uplink transmission, and / or conflict between sideline reception and uplink transmission.

[0103] For example, when the sidelink reuses the reception capability with the uplink and downlink, there is a conflict between the sidelink reception and the downlink reception.

[0104] For another example, when the sidelink reuses the transmission capabilities of the uplink and downlink, there is a conflict between the sidelink transmission and the uplink transmission.

[0110] Optionally, in this embodiment of the present application, the first time domain resource satisfies at least one of the following conditions:

[0116] Optionally, the signaling is sidelink RRC signaling, or sidelink PC5 signaling (PC5 signal, PC5-S).

[0117] For example, when a side link 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 that carries signaling.

[0118] For another example, when a side link between the first terminal device and the second terminal device has been established, the first logical channel or logical channel group is a logical channel or logical channel group that carries data.

[0119] Optionally, the first propagation mode is broadcast, or the first propagation mode is unicast or multicast.

[0120] For example, when the side link between the first terminal device and the second terminal device is not established, the first propagation mode is broadcast.

[0123] Optionally, in an embodiment 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 downlink signaling.

[0124] 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, wherein 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.

If the first terminal device is in a connected state, that is, the uplink and downlink between the first terminal device and the first network device are established, the first network device can configure the first time domain resource and the second time domain resource by broadcasting or sending downlink signaling.

[0131] Furthermore, in Example 1, the first terminal device sends the second information to the second terminal device, and the second information is used to indicate the resource information for the sideline communication between the second terminal device and the first terminal device.

UE 1 may obtain the first time domain resource and the second time domain resource by receiving RRC signaling sent by NW 1. UE 1 may perform sidelink communication with UE 2 on the first time domain resource, and UE 1 may perform cellular communication with NW 1 on the second time domain resource.
