Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for terminal internal collaboration based on conditional triggering. Background Art

[0002] In order to support direct communication between terminal devices, a sidelink communication mode is introduced. Among them, sidelink communication has two transmission resource allocation modes: one is the dynamic scheduling mode of the network side device (mode 1), and the other is the mode in which the terminal device independently selects from the resource pool broadcast by the network side device (mode 2). The first terminal device in mode 2 can send IUC (inter-UE coordination) information to the second terminal device in mode 2, which can carry resource sets to provide assistance when the second terminal device makes resource selection.

[0003] In related technologies, the sending of IUC information supports a condition-based trigger mechanism. A first terminal device can choose to trigger the sending of IUC information to a second terminal device based on the trigger condition. However, the first terminal device does not know whether the second terminal device is in mode 2 or whether the second terminal device supports the IUC feature. If the first terminal device determines that the trigger condition is met and continues to send IUC information to the second terminal device, signaling waste will result. This is a problem that needs to be solved urgently. Summary of the Invention

[0004] The embodiments of the present disclosure provide a method and apparatus for terminal internal collaboration based on conditional triggering, which can prevent a first terminal device from continuously sending IUC information to a second terminal device when an IUC trigger condition is met, thereby avoiding signaling waste, avoiding interference with the second terminal device, and saving energy consumption of the first terminal device.

[0005] In a first aspect, an embodiment of the present disclosure provides a terminal internal collaboration method based on conditional triggering, which is executed by a first terminal device.

[0006] In this technical solution, a first terminal device, in response to a trigger condition for sending intra-terminal collaboration IUC information to a second terminal device being met, sends IUC information to the second terminal device, where the IUC information carries a resource set. A counter is updated based on whether data sent by the second terminal device is received on the resource set. In response to the counter reaching a preset value and the trigger condition being met, the first terminal device stops sending the IUC information to the second terminal device. This prevents the first terminal device from continuously sending IUC information to the second terminal device when the IUC trigger condition is met, thus avoiding signaling waste, interference with the second terminal device, and energy consumption of the first terminal device.

[0007] In a second aspect, an embodiment of the present disclosure provides another terminal internal collaboration method based on conditional triggering, which is executed by a network side device, and the method includes: sending first indication information or second indication information to a first terminal device, wherein the first indication information is used to indicate a preset value of a counter, and the second indication information is used to indicate a first preset value of the first counter and / or a second preset value of the second counter,

[0008] The preset value is used to instruct the first terminal device to stop sending the IUC information to the second terminal device when the counter reaches the preset value based on whether the data sent by the second terminal device is received on the resource set and the triggering condition for sending the IUC information to the second terminal device is met;

[0009] The first preset value is used to instruct the first terminal device to stop sending the IUC information to the second terminal device when the first counter reaches the first preset value based on whether data sent by the second terminal device is received on the resource set and a triggering condition for sending the IUC information to the second terminal device is met;

[0051] In order to better understand the method and apparatus for inter-terminal collaboration based on conditional triggering disclosed in the embodiments of the present disclosure, the communication system to which the embodiments of the present disclosure are applicable is first described below.

[0052] See Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure.

Figure 1 The number and form of the devices shown are for example only and do not constitute a limitation on the embodiments of the present disclosure. In actual applications, two or more network-side devices and two or more terminal devices may be included. Figure 1 The communication system 10 shown includes a network-side device 101 and a terminal device 102 as an example.

For example, the network side device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiment of the present disclosure does not limit the specific technology and specific device form adopted by the base station. The base station provided in the embodiment of the present disclosure can be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU can also be called a control unit.

[0055] The terminal device 102 in the embodiment of the present disclosure is an entity on the user side for receiving or transmitting signals, such as a mobile phone. The terminal device can also be called a terminal device (terminal), user equipment (UE), mobile station (MS), mobile terminal device (MT), etc. The terminal device can be a car with communication function, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in self-driving (self-driving), a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in smart city (smart city), a wireless terminal device in smart home (smart home), etc. The embodiment of the present disclosure does not limit the specific technology and specific device form adopted by the terminal device.

[0056] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0057] The following describes in detail a method and apparatus for inter-terminal collaboration based on conditional triggering provided by the present disclosure with reference to the accompanying drawings.

[0058] To support direct communication between end devices, SideLink was introduced. The interface between end devices is PC-5. Based on the correspondence between the sending and receiving end devices, SideLink supports three transmission modes: unicast, multicast, and broadcast.

[0059] There are two ways to allocate transmission resources in Sidelink communication: one is dynamic scheduling by the network-side device (mode 1), and the other is autonomous selection by the terminal device from the resource pool broadcast by the network-side device (mode 2). Dynamic scheduling is when the network-side device dynamically allocates transmission resources on the sidelink to the terminal device based on the cached data reported by the terminal device, while autonomous selection is when the terminal device randomly selects transmission resources from the resource pool broadcast or pre-configured by the network-side device. The specific allocation method used is configured by the network-side device through RRC (Radio Resource Control) signaling. Sidelink communication supports the reporting of SUI (Sidelink UE information). SUI is auxiliary information sent between the terminal device and the network-side device. A terminal device in a connected state can report auxiliary information through SUI to assist the network-side device in resource configuration, SRB (signaling radio bearers) / DRB (data radio bearers) configuration, etc. A terminal device in a connected state can also report auxiliary information through UAI (UE assistance information). Reporting auxiliary information through UAI requires the network side device to be enabled through RRC signaling first.

[0060] In order to assist the peer terminal device to make better resource selection and avoid conflicts with other terminal devices, Release 17 (R17) introduces the Inter-UE coordination mechanism. UE-A in mode 2 can send an IUC (inter-UE coordination) MAC CE (media access control element) to the peer UE-B in mode 2. The MAC CE may carry a preferred resource set or a non-preferred resource set to assist the peer UE-B in resource selection. If the IUC MAC CE carries a preferred resource set, UE-B can only use the resources indicated by the preferred resource set to send data to UE-A and cannot use them to send data to other UEs. If the ICU MAC CE carries a non-preferred resource set, UE-B cannot use the resources indicated by the non-preferred resource set when sending data to UE-A.

[0061] IUC has two triggering modes: request-based IUC mechanism and condition-based IUC mechanism. The request-based IUC mechanism means that UE-A triggers the sending of IUC MAC CE only after receiving the IUC-request (IUC request) sent by UE-B through PC-5, while the condition-based IUC mechanism is that UE-A determines whether the triggering conditions are met. If the triggering conditions are met, UE-A can automatically trigger the sending of IUC MAC CE based on the implementation choice. Among them, the request-based IUC mechanism can limit the peer UE to send IUC MAC CE within the latency bound by configuring a latency bound. The UE can configure the latency bound (sl-LatencyBoundIUC-Report-r17) for the peer UE through PC5-RRC signaling. The UE maintains a timer (sl-IUC-ReportTimer) for each unicast link. The value of sl-IUC-ReportTimer is equal to the IUC latency requirement indicated by sl-LatencyBoundIUC-Report-r17. Latency bound is not applicable to the IUC mechanism based on conditional triggering. Both IUC information and IUC-request are carried by MAC CE. The format of IUC MAC CE is as follows: Figure 2 As shown in the figure, “R” represents a reserved bit.

[0062] In the related art, the first terminal device does not know whether the second terminal device is in mode 1 or mode 2, nor does it know whether the second terminal device supports the IUC feature. If the first terminal device determines that the trigger condition is met and continuously sends IUC information to the second terminal device, it will cause signaling waste, which is a problem that needs to be solved urgently.

[0063] Based on this, in an embodiment of the present disclosure, a method and apparatus for inter-terminal collaboration based on conditional triggering are provided. When a trigger condition for sending IUC information to a second terminal device is met, a first terminal device sends IUC information carrying a resource set to the second terminal device. A counter is updated based on whether data sent by the second terminal device is received on the resource set. When the counter reaches a preset value, the sending of IUC information to the second terminal device is stopped, even if the trigger condition is met. This prevents the first terminal device from continuously sending IUC information to the second terminal device when the IUC trigger condition is met, thereby avoiding signaling waste, preventing interference with the second terminal device, and saving energy consumption of the first terminal device.

[0064] It should be noted that the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in the embodiments of the present disclosure can be implemented individually, or can be implemented together with the methods of other embodiments of the embodiments of the present disclosure, or can be implemented together with some methods in other related technologies individually or in combination; the embodiments of the present disclosure do not limit this.

[0065] In addition, in order to facilitate understanding of the embodiments of the present disclosure, the following points are explained.

[0066] First, in this disclosure, "used to indicate" can include being used for direct indication and being used for indirect indication. When describing that a certain indication information is used to indicate A, it can include that the indication information directly indicates A or indirectly indicates A, but it does not mean that the indication information must include A.

[0067] The information indicated by the indication information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, it is also possible to use the arrangement order of each piece of information that is agreed in advance (for example, stipulated in the protocol) to achieve the indication of specific information, thereby reducing the indication overhead to a certain extent. At the same time, it is also possible to identify the common parts of each piece of information and indicate them uniformly to reduce the indication overhead caused by indicating the same information separately.

[0068] Second, the first, second, and various numbers in this disclosure are only used for the convenience of description and are not intended to limit the scope of the embodiments of this disclosure, for example, to distinguish different messages, different terminal devices, etc.

[0069] Third, in the present disclosure, the first terminal device establishes a PC5 connection with the second terminal device, and both support sidelink communication.

[0070] Fourth, in the present disclosure, the network side device is a network side device that supports sidelink specific, which is exemplarily indicated by SIB12 (System Information Block 12).

[0071] Fifth, the "protocol" involved in the embodiments of the present disclosure may refer to a standard protocol in the communication field, for example, it may include an LTE protocol, a NR protocol, and related protocols used in future communication systems, and the present disclosure does not limit this.

[0072] See Figure 3 , Figure 3 This is a flowchart of a terminal internal collaboration method based on conditional triggering provided by an embodiment of the present disclosure.

[0073] like Figure 3 As shown, the method is executed by the first terminal device, and the method may include but is not limited to the following steps:

[0074] S31: In response to a trigger condition for sending terminal internal collaboration IUC information to the second terminal device being met, IUC information is sent to the second terminal device, where the IUC information carries a resource set.

[0075] In an embodiment of the present disclosure, the first terminal device may send IUC information to the second terminal device when a triggering condition for sending IUC information to the second terminal device is met, wherein the IUC information may be an IUC MAC CE.

[0076] The triggering condition for sending the IUC information to the second terminal device may be a condition for sending the IUC information to the second terminal device in the related art, and the embodiment of the present disclosure does not impose any specific limitation on this.

[0077] In the embodiment of the present disclosure, a PC5 connection is established between the first terminal device and the second terminal device, and both the first terminal device and the second terminal device support sidelink communication.

[0078] The IUC MAC CE may carry a resource set, which may indicate resources that the second terminal device can use when sending data to the first terminal device, or indicate resources that the second terminal device cannot use when sending data to the first terminal device.

[0079] Exemplarily, the resource set indicates resources that the second terminal device can use when sending data to the first terminal device, for example, a preferred resource set.

[0080] Exemplarily, the resource set indicates resources that the second terminal device cannot use when sending data to the first terminal device, for example, a non-preferred resource set.

[0081] It can be understood that, when the resource set indicates the resources that the second terminal device can use when sending data to the first terminal device, if the second terminal device uses the resources indicated by the resource set to send data to the first terminal device, it means that the second terminal device is in mode 2 and supports the IUC feature. On the contrary, if the first terminal device does not receive the data sent by the second terminal device, or the second terminal device does not use the resources indicated by the resource set to send data to the first terminal device, it means that the second terminal device may not be in mode 2, or does not support the IUC feature.

[0082] It can be understood that, when the resource set indicates resources that the second terminal device cannot use when sending data to the first terminal device, if the second terminal device does not use the resources indicated by the resource set to send data to the first terminal device, it means that the second terminal device is in mode 2 and supports the IUC feature. On the contrary, if the first terminal device does not receive the data sent by the second terminal device, or the second terminal device uses the resources indicated by the resource set to send data to the first terminal device, it means that the second terminal device may not be in mode 2, or does not support the IUC feature.

[0083] It should be noted that when the trigger condition for sending IUC information to the second terminal device is met, the first terminal device sends IUC information carrying a resource set to the second terminal device, wherein the resource set may be a preferred resource set or a non-preferred resource set. The first terminal device may determine, based on implementation or based on an instruction from a network-side device or based on a protocol agreement, whether to send IUC information carrying a preferred resource set to the second terminal device when the trigger condition is met, or to send IUC information carrying non-preferred resources to the second terminal device when the trigger condition is met. The trigger conditions for the first terminal device to send IUC information carrying different types of resource sets may be the same or different, and the embodiments of the present disclosure do not impose specific restrictions on this.

[0084] S32: Update the counter according to whether data sent by the second terminal device is received on the resource set.

[0085] S33: In response to the counter reaching a preset value and satisfying a trigger condition, stop sending the IUC information to the second terminal device.

[0086] In the embodiment of the present disclosure, the first terminal device can determine whether the second terminal device is in mode 2 and supports the IUC feature based on whether the first terminal device receives data sent by the second terminal device on the resource set.

[0087] Based on this, the first terminal device updates a counter according to whether data sent by the second terminal device is received on the resource set.

[0088] Among them, the first terminal device and the second terminal device can establish a unicast connection, the first terminal device maintains a counter, the network side device can configure the counter for the first terminal device through RRC signaling, or the first terminal device can determine the counter based on implementation.

[0089] It should be noted that the counter maintained by the first terminal device can be maintained based on the unicast link, and a counter can be maintained for each unicast connection. It can be understood that the first terminal device can establish unicast connections with different second terminal devices respectively, and the first terminal device can maintain a counter for each unicast connection.

[0090] The initial value of the counter is 0.

[0091] It can be understood that the resource set carried by the IUC information can indicate the resources that the second terminal device can use when sending data to the first terminal device, such as: the preferred resource set, or indicate the resources that the second terminal device cannot use when sending data to the first terminal device, such as: the non-preferred resource set.

[0092] In some possible implementations, when the resource set is a preferred resource set, the second terminal device is in mode 2 and supports the IUC feature, data can be sent to the first terminal device on the preferred resource set according to the IUC information. The first terminal device can continue to execute subsequent processes, and there is no problem of signaling waste.

[0093] On the contrary, if the second terminal device is not in mode 2 or does not support the IUC feature, it may not send data to the first terminal device, or may not send data to the first terminal device on the resources indicated by the preferred resource set. At this time, the first terminal device can update the counter.

[0094] Exemplarily, when no data sent by the second terminal device is received, the counter is incremented by 1, or when data sent by the second terminal device is received on resources other than the resources indicated by the preferred resource set, the counter is incremented by 1 to update the counter.

[0095] It is understandable that when the trigger conditions are met, the first terminal device will continuously send IUC information to the second terminal device. If the status of the second terminal device remains unchanged, or is always unable to be in mode 2, or is always unable to support the IUC feature, it will cause signaling waste and cause interference to the second terminal device.

[0096] Based on this, in the disclosed embodiment, the first terminal device continuously sends IUC information to the second terminal device when a trigger condition is met. If the second terminal device remains in the same state, or is unable to enter mode 2 or support the IUC feature, the counter is continuously updated. In this case, if the counter reaches a preset value, the first terminal device stops sending IUC information to the second terminal device even when the trigger condition is met. This avoids signaling waste, interference with the second terminal device, and energy consumption of the first terminal device.

[0097] In other possible implementations, when the resource set is a non-preferred resource set, the second terminal device is in mode 2 and supports the IUC feature, data can be sent to the first terminal device on resources other than the resources indicated by the non-preferred resource set according to the IUC information. The first terminal device can continue to execute subsequent processes, and there is no problem of signaling waste.

[0098] On the contrary, if the second terminal device is not in mode 2 or does not support the IUC feature, it may not send data to the first terminal device, or it may send data to the first terminal device on the resources indicated by the non-preferred resource set. At this time, the first terminal device can update the counter.

[0099] Exemplarily, when no data sent by the second terminal device is received, the counter is incremented by 1, or when data sent by the second terminal device is received on resources indicated by a non-preferred resource set, the counter is incremented by 1 to update the counter.

[0100] It is understandable that when the trigger conditions are met, the first terminal device will continuously send IUC information to the second terminal device. If the status of the second terminal device remains unchanged, or is always unable to be in mode 2, or is always unable to support the IUC feature, it will cause signaling waste and cause interference to the second terminal device.

[0101] Based on this, in the disclosed embodiment, the first terminal device continuously sends IUC information to the second terminal device when a trigger condition is met. If the second terminal device remains in the same state, or is unable to enter mode 2 or support the IUC feature, the counter is continuously updated. In this case, if the counter reaches a preset value, the first terminal device stops sending IUC information to the second terminal device even when the trigger condition is met. This avoids signaling waste, interference with the second terminal device, and energy consumption of the first terminal device.

[0102] It is understandable that in the above implementations, the resource sets carried in the IUC information sent by the first terminal device to the second terminal device when the trigger condition is satisfied are described as the same type of resource sets. It is conceivable that the first terminal device may carry the preferred resource set in the IUC information sent to the second terminal device when the trigger condition is satisfied for the first time, carry the non-preferred resource set in the IUC information sent to the second terminal device when the trigger condition is satisfied for the second time, carry the non-preferred resource set in the IUC information sent to the second terminal device when the trigger condition is satisfied for the third time, carry the non-preferred resource set in the IUC information sent to the second terminal device when the trigger condition is satisfied for the fourth time, and so on. When the first terminal device satisfies the trigger condition multiple times, the resource sets carried in the IUC information sent to the second terminal device may alternate between the preferred resource set and the non-preferred resource set.

[0103] Based on this, in some further possible implementations, the first terminal device sends IUC information to the second terminal device when a triggering condition for sending IUC information to the second terminal device is initially met, wherein the IUC information carries a preferred resource set.

[0104] Among them, when the second terminal device is not in mode 2 or does not support the IUC feature, it may not send data to the first terminal device, or may not send data to the first terminal device on the resources indicated by the preferred resource set. At this time, the first terminal device can update the counter, exemplarily, the counter is increased by 1.

[0105] Afterwards, when the trigger conditions are met, the first terminal device will continuously send IUC information to the second terminal device. If the IUC information carries a non-preferred resource set, the second terminal device may not send data to the first terminal device if it is not in mode 2 or does not support the IUC feature, or may send data to the first terminal device on the resources indicated by the non-preferred resource set. At this time, the first terminal device can update the counter, exemplarily, the counter is increased by 1.

[0106] In this case, if the counter reaches a preset value, the first terminal device also stops sending IUC information to the second terminal device when the trigger condition is met. This can avoid signaling waste, interference to the second terminal device, and save energy consumption of the first terminal device.

[0107] Of course, in the above implementation method, the first terminal device sends IUC information to the second terminal device when the trigger condition for sending IUC information to the second terminal device is initially met, wherein the IUC information can also carry a non-preferred resource set, and the first terminal device updates the counter according to whether the data sent by the second terminal device is received on the non-preferred resource set. After that, the first terminal device will continue to send IUC information to the second terminal device when the trigger condition is met, wherein the IUC information can also carry a preferred resource set, and the first terminal device updates the counter according to whether the data sent by the second terminal device is received on the preferred resource set. The embodiment of the present disclosure does not impose specific restrictions on this.

[0108] In the embodiment of the present disclosure, when the counter of the first terminal device reaches a preset value, even if the trigger condition is met, the first terminal device stops sending IUC information to the second terminal device. This can avoid signaling waste, interference to the second terminal device, and save energy consumption of the first terminal device.

[0109] Among them, the first terminal device can determine the preset value based on implementation, network side device indication, protocol agreement, or pre-configuration. The preset value can be set as needed. For example, the preset value is 1, 2, or 5, etc., and the embodiment of the present disclosure does not impose specific restrictions on this.

[0110] By implementing the embodiments of the present disclosure, a first terminal device, in response to a trigger condition for sending intra-terminal collaboration IUC information to the second terminal device being met, sends IUC information to the second terminal device, where the IUC information carries a resource set; updates a counter based on whether data sent by the second terminal device is received on the resource set; and stops sending IUC information to the second terminal device in response to the counter reaching a preset value and meeting the trigger condition. This avoids signaling waste, interference with the second terminal device, and energy consumption of the first terminal device.

[0111] In some embodiments, the resource set includes a preferred resource set and / or a non-preferred resource set, wherein the first terminal device updates the counter according to whether data sent by the second terminal device is received on the resource set, including at least one of the following:

[0119] The second resource location includes a time location and / or a frequency location, wherein the first terminal device can determine the second resource location for receiving data sent by the second terminal device.

[0120] Exemplarily, the first terminal device may determine the time position for receiving data sent by the second terminal device through a period, a subframe position, or a duration.

[0121] Exemplarily, the first terminal device may determine the frequency position for receiving data sent by the second terminal device through a PBR (Prioritised Bit Rate) position, a sub-bandwidth or a frequency.

[0132] In some embodiments, when the counter reaches a preset first value, the first terminal device stops sending IUC information to the second terminal device even if a trigger condition is met.

[0154] In the embodiment of the present disclosure, when the second counter reaches the second preset value, the first terminal device stops sending IUC information to the second terminal device even if the trigger condition is met.

The above embodiments are only for illustration and are not intended to be a specific limitation on the scope of protection of the embodiments of the present disclosure.

[0164] In one possible implementation, the counter includes a first counter. When the trigger condition for sending IUC information to the second terminal device is met, the first terminal device sends IUC information to the second terminal device, wherein the IUC information carries a preferred resource set. When the first terminal device does not receive data sent by the second terminal device, the first terminal device adds 1 to the first counter, and / or when the first terminal device receives data sent by the second terminal device at the first resource location and the first resource location does not overlap with the preferred resource set, the first counter adds 1.

[0171] In some embodiments, the first terminal device may determine the fourth value of the first preset value of the first counter based on a network device indication, implementation, or protocol agreement when it is unknown whether the second terminal device supports the IUC feature.

[0172] In some embodiments, the first terminal device may determine, based on a network device indication, implementation, or protocol agreement, the fifth value of the second preset value of the second counter when it is known that the second terminal device supports the IUC feature.

[0173] In some embodiments, the first terminal device may determine the sixth value of the second preset value of the second counter based on a network device indication, implementation, or protocol agreement when it is unknown whether the second terminal device supports the IUC feature.

[0175] Among them, the first terminal device determines the fifth value or sixth value of the second preset value of the second counter based on the indication of the network side device. It can be determined according to the second indication information sent by the network side device, or other information sent by the network side device can be reused. The embodiment of the present disclosure does not impose specific restrictions on this.

[0176] In some embodiments, when the first counter reaches the third value of the first preset value, the first terminal device stops sending IUC information to the second terminal device even if the trigger condition is met.

[0177] In some embodiments, when the first counter reaches the fourth value of the first preset value, the first terminal device stops sending IUC information to the second terminal device even if the trigger condition is met.

[0178] In some embodiments, when the second counter reaches the fifth value of the second preset value, the first terminal device stops sending IUC information to the second terminal device even if the trigger condition is met. This can avoid signaling waste, interference with the second terminal device, and save energy consumption of the first terminal device.

[0179] In some embodiments, when the second counter reaches the sixth value of the second preset value, the first terminal device stops sending IUC information to the second terminal device even if the trigger condition is met. This can avoid signaling waste, interference with the second terminal device, and save energy consumption of the first terminal device.

[0180] It should be noted that the above embodiments are not exhaustive and are only illustrations of some embodiments. The above embodiments can be implemented individually or in combination. The above embodiments are only for illustration and are not intended to be a specific limitation on the scope of protection of the embodiments of the present disclosure.

[0181] The third value of the first preset value of the first counter is less than or equal to the fourth value. For example, the third value is 1 and the fourth value is 2; or the third value is 2 and the fourth value is 5, or both the third value and the fourth value are 1, etc.

[0182] The fifth value of the second preset value of the second counter is less than or equal to the sixth value. For example, the fifth value is 1 and the sixth value is 2; or the fifth value is 2 and the sixth value is 5, or both the fifth value and the sixth value are 1, etc.

[0183] In the embodiment of the present disclosure, the initial value of the timer is 0, the initial value of the first counter is 0, and the initial value of the second counter is also 0.

[0184] It is understandable that the counter cannot be updated all the time and cannot be accumulated all the time. It needs to be reset to 0 when specific conditions are met. For example, it is automatically reset to 0 when it accumulates to a certain value, or it is reset to 0 when it accumulates to a value greater than a certain value and receives data sent by the second terminal device on the resource indicated by the resource set, or it can be reset to 0 based on its own implementation, or it can be reset to 0 based on the indication of the network side device, or it can be reset to 0 based on the protocol agreement, etc. The embodiments of the present disclosure do not impose specific restrictions on this.

[0185] It should be noted that the counter includes a first counter and / or a second counter. The first counter and / or the second counter cannot always be updated and cannot always be accumulated. When specific conditions are met, they need to be reset to 0. The way of resetting them to 0 is the same as or different from the way of resetting the counter to 0, and the way of resetting the first counter and the second counter to 0 can be the same or different.

[0186] In some embodiments, the first terminal device resets the counter to 0 in response to detecting that the channel occupancy rate CBR value is greater than a threshold value.

[0187] In an embodiment of the present disclosure, the first terminal device may reset the counter to 0 when detecting that the CBR (channel busy ratio) value is greater than a threshold value.

[0188] It is understandable that when the first terminal device detects that the CBR value is greater than the threshold value, the CBR value of the resources used by the first terminal device to send IUC information to the second terminal device is large, there may be poor communication, and the IUC information may not be accurately sent to the second terminal device. At this time, the counter is reset to 0.

[0189] In some embodiments, the first terminal device receives high-layer signaling sent by the network-side device, wherein the high-layer signaling is used to indicate the release of the side link SL connection with the second terminal device; and resets the counter to 0.

[0190] In an embodiment of the present disclosure, the first terminal device may also receive high-layer signaling sent by the network-side device, and reset the counter to 0 when the high-layer signaling indicates to release the side link SL connection with the second terminal device.

[0191] It can be understood that when the first terminal device receives the high-level signaling instruction sent by the network side device to release the side link SL connection with the second terminal device, the first terminal device releases the SL connection with the second terminal device. After that, the first terminal device will stop sending IUC information to the second terminal device, and the counter can be reset to 0 at this time.

[0192] See Figure 4 , Figure 4 This is a flowchart of another terminal internal collaboration method based on conditional triggering provided by an embodiment of the present disclosure.

[0193] like Figure 4 As shown, the method is executed by the first terminal device, and the method may include but is not limited to the following steps:

[0194] S41: In response to a trigger condition for sending the terminal internal collaboration IUC information to the second terminal device being met, IUC information is sent to the second terminal device, where the IUC information carries a preferred resource set.

[0270] S93: Receive second indication information sent by the network-side device, and determine a first preset value of the first counter and / or a second preset value of the second counter according to the second indication information.

[0271] In an embodiment of the present disclosure, a first terminal device receives second indication information sent by a network-side device, where the second indication information indicates a first preset value of a first counter. Thus, the first terminal device can determine the first preset value of the first counter based on the second indication information. For example, the first preset value is 1, 2, or 5, etc., and this embodiment of the present disclosure does not impose any specific limitation on this.

[0272] In an embodiment of the present disclosure, a first terminal device receives second indication information sent by a network-side device, where the second indication information indicates a second preset value of a second counter. Thus, the first terminal device can determine the second preset value of the second counter based on the second indication information.

[0273] The second indication information may be RRC signaling, or may be other signaling or messages, and the embodiment of the present disclosure does not impose any specific limitation on this.

[0274] S94: In response to the first counter reaching the first preset value and / or the second counter reaching the second preset value, and the triggering condition is met, stop sending the IUC information to the second terminal device.

[0275] In the embodiment of the present disclosure, when the first counter reaches the first preset value, the first terminal device stops sending IUC information to the second terminal device even if the trigger condition is met.

[0276] In the embodiment of the present disclosure, when the second counter reaches the second preset value, the first terminal device stops sending IUC information to the second terminal device even if the trigger condition is met.

[0277] It should be noted that the above embodiments are not exhaustive and are only illustrations of some embodiments. The above embodiments can be implemented individually or in combination. The above embodiments are only for illustration and are not intended to be a specific limitation on the scope of protection of the embodiments of the present disclosure.

[0278] It should be noted that, in the embodiment of the present disclosure, S91 to S94 can be implemented separately or in combination with any other steps in the embodiment of the present disclosure, for example, in combination with S31 to S33 and / or S81 to S83 in the embodiment of the present disclosure, and the embodiment of the present disclosure does not limit this.

[0279] See Figure 10 , Figure 10This is a flowchart of another terminal internal collaboration method based on conditional triggering provided by an embodiment of the present disclosure.

[0280] like Figure 10 As shown, the method is executed by the first terminal device, and the method may include but is not limited to the following steps:

[0281] S101: In response to a trigger condition for sending intra-terminal collaboration IUC information to a second terminal device being met, IUC information is sent to the second terminal device, where the IUC information carries a resource set.

[0282] S102: Update the counter according to whether data sent by the second terminal device is received on the resource set.

[0283] For the relevant description of S101 and S102 , reference can be made to the relevant description in the above embodiment, which will not be repeated here.

[0284] S103: In response to detecting that the channel occupancy rate CBR value is greater than the threshold value, resetting the counter to 0.

[0285] In an embodiment of the present disclosure, the first terminal device may reset the counter to 0 when detecting that the CBR (channel busy ratio) value is greater than a threshold value.

[0286] It is understandable that when the first terminal device detects that the CBR value is greater than the threshold value, the CBR value of the resources used by the first terminal device to send IUC information to the second terminal device is large, which may indicate poor communication and the IUC information may not be accurately sent to the second terminal device. In this case, the counter is reset to 0. This can avoid signaling waste, interference with the second terminal device, and energy consumption of the first terminal device.

[0287] It should be noted that, in the embodiments of the present disclosure, S101 to S103 can be implemented separately or in combination with any other steps in the embodiments of the present disclosure, for example, they can be implemented in combination with S31 to S33 and / or S41 to S43 and / or S51 to S53 and / or S61 to S63 and / or S71 to S74 and / or S81 to S83 and / or S91 to S94 in the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited to this.

[0288] See Figure 11 , Figure 11 This is a flowchart of another terminal internal collaboration method based on conditional triggering provided by an embodiment of the present disclosure.

[0289] like Figure 11 As shown, the method is executed by the first terminal device, and the method may include but is not limited to the following steps:

[0290] S111: In response to a trigger condition for sending terminal internal collaboration IUC information to the second terminal device being met, IUC information is sent to the second terminal device, where the IUC information carries a resource set.

[0291] S112: Update the counter according to whether data sent by the second terminal device is received on the resource set.

[0292] For the relevant description of S111 and S112, reference can be made to the relevant description in the above embodiment, which will not be repeated here.

[0293] S113: Receive high-layer signaling sent by the network-side device, where the high-layer signaling is used to instruct the release of the side link SL connection with the second terminal device.

[0294] S114: Reset the counter to 0.

[0295] In an embodiment of the present disclosure, the first terminal device may also receive high-layer signaling sent by the network-side device, and reset the counter to 0 when the high-layer signaling indicates to release the side link SL connection with the second terminal device.

[0296] It is understandable that, upon receiving a high-layer signaling instruction from the network-side device to release the side link SL connection with the second terminal device, the first terminal device releases the SL connection with the second terminal device. Thereafter, the first terminal device stops sending IUC information to the second terminal device, and the counter can be reset to 0. This avoids signaling waste, interference with the second terminal device, and energy consumption of the first terminal device.

[0297] It should be noted that, in the embodiments of the present disclosure, S111 to S114 can be implemented separately or in combination with any other steps in the embodiments of the present disclosure, for example, they can be implemented in combination with S31 to S33 and / or S41 to S43 and / or S51 to S53 and / or S61 to S63 and / or S71 to S74 and / or S81 to S83 and / or S91 to S94 in the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited to this.

[0301] The preset value is used to instruct the first terminal device to stop sending IUC information to the second terminal device when the update counter reaches the preset value based on whether data sent by the second terminal device is received on the resource set and the triggering condition for sending IUC information to the second terminal device is met;

[0302] The first preset value is used to instruct the first terminal device to stop sending IUC information to the second terminal device when the first counter reaches the first preset value based on whether data sent by the second terminal device is received on the resource set and a triggering condition for sending IUC information to the second terminal device is met;

[0303] The second preset value is used to instruct the first terminal device to stop sending IUC information to the second terminal device when the second counter is updated to reach the second preset value based on whether data sent by the second terminal device is received on the resource set and the trigger condition for sending IUC information to the second terminal device is met.

[0304] In an embodiment of the present disclosure, a network side device sends first indication information to a first terminal device, where the first indication information is used to indicate a preset value of a counter, wherein the preset value is used to instruct the first terminal device to stop sending IUC information to the second terminal device when the counter reaches the preset value based on whether data sent by the second terminal device is received on a resource set and a trigger condition for sending IUC information to the second terminal device is met.

[0305] In an embodiment of the present disclosure, a network side device sends second indication information to a first terminal device, where the second indication information is used to indicate a first preset value of a first counter, and the first preset value is used to instruct the first terminal device to stop sending IUC information to the second terminal device when the first counter is updated to reach the first preset value based on whether data sent by the second terminal device is received on a resource set and a trigger condition for sending IUC information to the second terminal device is met.

[0306] In an embodiment of the present disclosure, a network side device sends second indication information to a first terminal device, where the second indication information is used to indicate a second preset value of a second counter, and the second preset value is used to instruct the first terminal device to stop sending IUC information to the second terminal device when the second counter is updated to reach the second preset value based on whether data sent by the second terminal device is received on a resource set and a trigger condition for sending IUC information to the second terminal device is met.

[0307] The first indication information and / or the second indication information may be RRC signaling, or may be other signaling or messages, and the embodiment of the present disclosure does not impose any specific limitation on this.

[0308] By implementing the embodiments of the present disclosure, the network-side device sends first indication information or second indication information to the first terminal device, where the first indication information is used to indicate the preset value of the counter, and the second indication information is used to indicate the first preset value of the first counter and / or the second preset value of the second counter. This avoids signaling waste, interference with the second terminal device, and energy consumption of the first terminal device.
