In order to better understand the embodiments of the present application, the following terms refer to the embodiments of the present application:
carrier waves (carrier signals or carriers) are electrical waves generated by oscillators and transmitted over communication channels, which are modulated to carry voice or other information. The carrier frequency is usually higher than the frequency of the input signal, which is a high frequency signal that is modulated onto a high frequency carrier as if it were riding a train of high-speed rails or an aircraft, and then transmitted and received. A carrier wave is the physical basis and vehicle upon which information (voice and data) is conveyed.
The resource pool is a method for allocating and managing multidimensional resources in a communication system, and the definition of the resource pool is as follows: all available resources in the system, including antenna units, power, frequency, time slots, code words, space resources and the like, are gathered together, and are scheduled and allocated uniformly by a specific resource management module in the system. The scheduling and allocation mode of the available resources in the resource pool is not fixed, and can be performed according to the requirements of a specific system, or set priorities for certain resources according to a certain criterion, and further optimize the allocation and management strategy of the wireless resources according to a certain criterion. In the embodiment of the present application, one carrier may include a plurality of resource pools.
A direct link (SL) is a Device to Device Communication technology, which is different from the normal wireless cellular network Communication. In a conventional cellular network, a terminal device may communicate with a base station device, and a link between the terminal device and the base station device is called Uplink (Uplink) or Downlink (Downlink), and an interface is called Uu interface. In the object direct connection communication, the terminal device directly communicates with the terminal device, a link between the terminal device and the terminal device is called a direct connection link, and an interface is called a PC5 interface. There are two resource allocation approaches on direct links: mode 1 and Mode 2. The Mode 1 resource allocation Mode is that a base station allocates resources to a sending terminal device in a centralized manner, and a sending end (namely, the terminal device sending data) directly uses the resources allocated by the base station to send data to a receiving end (namely, the terminal device receiving data); and the Mode2 resource allocation Mode is that the sending end autonomously selects an available carrier or a resource pool for data transmission in a sensing Mode. Usually, a sending end is configured with a plurality of resource pools, and different resource pools can be configured differently, so that requirements of different services of the sending end can be met. The sending end can select a resource pool meeting the service requirement from a plurality of resource pools, and when the selected resource pools are still a plurality, the sending user randomly selects one resource pool for data transmission.
Listen Before Talk (LBT) is a widely used technique in radio communication, in which a radio transmitter first listens to its radio environment Before starting transmission, detects whether a channel is idle, and waits for transmission when the channel is idle if the channel is in a busy state, so as to avoid channel access collision and realize channel spectrum sharing.
In the embodiment of the present application, LBT failure refers to: when a terminal device at a sending end uses a certain resource on a certain direct connection link, the terminal device detects that the resource is in an unavailable state. For example, when the terminal device at the transmitting end detects that the resource is in a busy state, it may determine that an LBT failure occurs for the resource.
In order to better understand the embodiments of the present application, a network architecture to which the embodiments of the present application are applicable is described below.
Referring to fig. 1, fig. 1 is a diagram illustrating a communication network system architecture according to an embodiment of the present disclosure. As shown in fig. 1, the communication network system architecture diagram includes a network device and two terminal devices. The two terminal devices include a terminal device at a transmitting end and a terminal device at a receiving end. And the terminal equipment at the sending end can send data information to the terminal equipment at the receiving end through the direct connection link. The direct link may be operating in an unlicensed frequency band. The terminal device at the transmitting end may be configured with transmission resources, such as a carrier and a resource pool, on the direct connection link. It should be noted that, the terminal device connected to the network device may be a sending end or a receiving end, and the specific sending end or the receiving end depends on whether the terminal device has data to send to other terminal devices. If yes, the terminal equipment is the terminal equipment of the sending end; and if other terminal equipment sends data to the terminal equipment, the terminal equipment is the terminal equipment of the receiving end.
The terminal equipment at the sending end can acquire resources to communicate with the terminal equipment at the receiving end in a Mode of Mode 2. Specifically, the terminal device at the sending end may detect a certain resource, detect whether the resource is already occupied, and if not, may use the resource to perform communication.

In order to determine available resources for performing communication on a direct link, embodiments of the present application provide a resource processing method and apparatus, and details of the resource processing method and apparatus provided in the embodiments of the present application are further described below.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a resource processing method according to an embodiment of the present disclosure. The resource processing method includes operations 210 to 220 as follows. The method execution main body shown in fig. 2 may be a terminal device or a chip in the terminal device. Specifically, the method shown in fig. 2 is executed by a terminal device whose main body is a sending end, and at this time, the sending end terminal device needs to send data to a receiving end terminal device. In the embodiment of the present application, unless otherwise specified, all the terminal devices refer to terminal devices at a transmitting end. When the terminal device executes the flow shown in fig. 2, the following steps may be included:
210. and if the first resource meets the condition of continuous listen before send LBT failure, determining that the first resource triggers the continuous LBT failure.
Wherein the first resource belongs to a first radio link. The terminal equipment can acquire the first resource in a Mode of Mode2 when data needs to be sent. The terminal device may detect whether the first resource satisfies a consecutive LBT failure condition, and if so, may trigger the consecutive LBT failure of the first resource.
Specifically, the terminal device may detect whether indication information is included in the first resource, where the indication information is used to indicate that the first resource is occupied. If the terminal device detects the indication information, it determines that the first resource is occupied, and may determine that an LBT failure event has occurred on the first resource. Alternatively, the terminal device receives a failure indication from a lower layer (lower layer) of the terminal device, and determines that an LBT failure event has occurred on the first resource. The lower layer may be a physical layer of the terminal device. The Failure Indication may be an LBT Failure Indication (LBT Failure Indication). If the terminal device detects that the first resource meets the conditions of continuous LBT failure, it may determine that the first resource triggers the continuous LBT failure.
Alternatively, the consecutive LBT failure condition may be: the number of LBT failure events occurring on the first resource reaches a first number threshold. The first number threshold may be configured by the terminal device or the network device, and is not limited.
Optionally, the consecutive LBT failure condition may also be: the number of LBT failure events occurring on the first resource reaches a second number threshold and no LBT success events occur within the first time period. The first time period takes the moment when the number of times of LBT failure events continuously occurring on the first resource reaches the second number threshold value as the starting time point; the second number threshold may be configured by the terminal device or the network device, and is not limited. The LBT success event may refer to that the terminal device does not receive an LBT failure indication from a lower layer of the terminal device. This condition may be implemented by a first timer and a first counter. When an LBT failure event occurs on the first resource, the first counter may perform an add operation; starting a first timer when the first counter reaches a second number threshold, terminating the first timer if an LBT success event occurs during the operation of the first timer, and resetting the first counter, e.g. setting the first counter to an initial value; if the first timer runs out of time, that is, no LBT success event occurs during the first timer running, the terminal device may determine that the first resource satisfies a continuous LBT failure condition.
Optionally, the consecutive LBT failure condition may also be: the number of LBT failure events occurring on the first resource reaches a third number threshold, and the interval between two adjacent LBT failure events is less than a second time period. Wherein, the third number threshold may be configured by the terminal device or the network device, and is not limited; the second time period may also be configured by the terminal device or the network device. This condition may be implemented by a second timer and a second counter. When an LBT failure event occurs on the first resource for one time, the second counter may perform an addition operation, and start or restart the second timer; resetting the second counter when the second timer times out, for example, setting the second counter to an initial value; when the second counter reaches the third number threshold, the terminal device may determine that the first resource satisfies the consecutive LBT failure condition.
It should be noted that the above three consecutive LBT failure conditions may be applicable to a carrier and also to a resource pool. And the first quantity threshold corresponding to the carrier may be different from the first quantity threshold corresponding to the resource pool, and the second quantity threshold corresponding to the carrier may be different from the second quantity threshold corresponding to the resource pool, and so on.
220. Determining a second resource, the second resource not triggering a consecutive LBT failure, the first resource and the second resource belonging to a first radio link.
After the terminal device determines that consecutive LBT failures occur on the first resource, it may determine the second resource. Wherein the first resource and the second resource belong to a first radio link. The second resource does not trigger a consecutive LBT failure, i.e., the second resource does not experience a consecutive LBT failure. If the terminal device determines the second resource in the first wireless link, the terminal device may communicate with a target terminal device through the second resource, where the target terminal device is a terminal device of the receiving end. The first resource and the second resource may be carriers or resource pools, and the first resource or the second resource is determined by the terminal device.
It should be noted that the frequency range corresponding to the second resource does not intersect with the frequency range corresponding to the third resource. Wherein the third resource is a resource that triggers a consecutive LBT failure in the first radio link. The third resource may be a plurality of resources that triggered consecutive LBT failures, and the frequency range corresponding to the third resource may be a set of frequency ranges of the plurality of resources that triggered consecutive LBT failures.
For example, fig. 3 is a schematic diagram of a frequency range distribution of the third resource. In fig. 3, the third resource includes resource 1, resource 2, and resource 3, and resource 1, resource 2, and resource 3 all trigger consecutive LBT failures, i.e., all are unavailable resources. Wherein, resource 1, resource 2, and resource 3 may be carriers or resource pools. The frequency range of the resource 1 is 100Mhz to 120Mhz, the frequency range of the resource 2 is 70Mhz to 80Mhz, and the frequency range of the resource 3 is 60Mhz to 70Mhz. When determining the second resource, the terminal device needs to exclude the resource having an intersection with the frequency range of the third resource, so as to ensure that the finally determined second resource does not have an intersection with the third resource. For example, the frequency range of the second resource may be 80Mhz to 100Mhz, 85Mhz to 95Mhz, 120Mhz to 140Mhz, and so on.
It should be noted that, since the carrier and the resource pool are both a frequency range, there is no carrier or resource pool of a certain frequency, for example, there is no carrier with a frequency of 80Mhz or resource pool with a frequency of 120Mhz, so the frequency range is an open interval. For example, the frequency range of resource 1: 100Mhz to 120Mhz, expressed in intervals as (100Mhz, 120Mhz), excluding the two endpoints of 100Mhz and 120 Mhz.
In a possible implementation manner, if the number of the fourth resources is greater than N, it is determined that a radio link failure event occurs on the first radio link, where N is a positive integer and may be configured by a terminal device or a network device; the fourth resource is a resource that triggers consecutive LBT failures in the first radio link, and the fourth resource may be a carrier. That is, if the number of carriers triggering consecutive LBT failures in the first radio link is greater than N, it may be determined that a radio link failure event occurs in the first radio link, that is, it is determined that the first radio link is not capable of performing normal communication. Then the terminal device reports the identifier information of the fourth resource to the network device, and/or the identifier information of each resource pool in the fourth resource that triggers the failure of the continuous LBT. Further, the terminal device may also report to the network device that the radio link failure event occurs on the first radio link.
In a possible implementation manner, if the number of the fifth resources is greater than M, it is determined that a radio link failure event occurs on the first radio link. Wherein, M is a positive integer, and can be configured by a terminal device or a network device; the fifth resource is a resource that triggers consecutive LBT failures in the first radio link, and the fifth resource may be a resource pool. That is, if the number of resource pools triggering consecutive LBT failures in the first radio link is greater than M, it may be determined that a radio link failure event occurs in the first radio link, that is, it is determined that the first radio link is not capable of performing normal communication. The terminal device reports the identifier information of the fifth resource and/or the identifier information of the carrier where the fifth resource is located to the network device. Further, the terminal device may also report to the network device that the radio link failure event occurs on the first radio link.
In a possible implementation manner, if the number of the sixth resource is greater than N, it is determined that a radio link failure event occurs on the first radio link. The sixth resource is a carrier, the number of resource pools triggering consecutive LBT failures in each sixth resource is greater than M, and N and M are positive integers. That is, if there are X carriers in the first radio link, where X is a positive integer greater than N, and the number of resource pools triggering consecutive LBT failures on each carrier in the X carriers is greater than M, it may be determined that a radio link failure event occurs on the first radio link, that is, it is determined that the first radio link is unable to perform normal communication. The terminal device reports the sixth resource identification information to the network device, and/or the identification information of the resource pool in which the continuous LBT failure is triggered in the sixth resource. Further, the terminal device may also report to the network device that the radio link failure event occurs on the first radio link.
In one possible implementation, if the second resource is not determined, it is determined that a radio link failure event occurs on the first radio link. It can be understood that, since the second resource is a resource that does not trigger a consecutive LBT failure, and the frequency range of the second resource does not intersect with the frequency range corresponding to the resource that has triggered the consecutive LBT failure. If the terminal device does not determine the second resource on the first radio link, it indicates that the first radio link does not have the second resource, so that all the resources of the first radio link trigger the continuous LBT failure, or a frequency range corresponding to any resource in the first radio link intersects with a frequency range corresponding to the resource triggering the continuous LBT failure. The terminal device may report that the radio link failure event occurs on the first radio link by the network device. Since the network device can acquire the information of all resources on the first radio link, the terminal device does not need to report the identification information of each resource.
Optionally, the terminal device reports a radio link failure event occurring in the first radio link, and/or identifier information of the resource that triggered the consecutive LBT failure, may be reported through direct link user equipment information SidelinkUEInformation.
By the embodiment of the application, the terminal device can trigger the continuous LBT failure of the first resource under the condition that the first resource meets the continuous LBT failure condition, and further can determine the second resource, wherein the second resource is the resource which does not trigger the continuous LBT failure. The first resource and the second resource both belong to a first radio link, a frequency range corresponding to the second resource does not intersect with a frequency range corresponding to a third resource, and the third resource is a resource that triggers a continuous LBT failure in the first radio link. If the terminal device determines the second resource, the terminal device at the receiving end can communicate through the second resource. By the method, corresponding resource processing can be better performed according to LBT, so that the terminal equipment determines available resources on the first wireless link to perform communication on the direct link.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating another resource processing method according to an embodiment of the present application. The resource processing method includes operations 410 to 420 as follows. The method execution subject shown in fig. 4 may be a terminal device or a chip in the terminal device. Specifically, the method shown in fig. 4 is executed by a terminal device whose main body is a sending end, and at this time, the sending end terminal device needs to send data to a receiving end terminal device. In the embodiment of the present application, unless otherwise specified, all terminal devices refer to terminal devices at a sending end. When the terminal device executes the flow shown in fig. 4, the following steps may be included:
410. and if the first resource meets the condition of continuous listen before send LBT failure, determining that the first resource triggers the continuous LBT failure.
Wherein the first resource belongs to a first radio link. The terminal device may obtain the first resource in a Mode of Mode2 when data needs to be sent. The terminal device may detect whether the first resource satisfies a consecutive LBT failure condition, and if so, may trigger the consecutive LBT failure of the first resource.
Specifically, the terminal device may detect whether indication information is included in the first resource, where the indication information is used to indicate that the first resource is occupied. If the terminal device detects the indication information, it determines that the first resource is occupied, and may determine that an LBT failure event has occurred on the first resource. Alternatively, the terminal device receives a failure indication from a lower layer of the terminal device, and determines that an LBT failure event has occurred on the first resource. The lower layer may be a physical layer of the terminal device. The failure indication may be an LBT failure indication. If the terminal device detects that the first resource meets the conditions of continuous LBT failure, it may determine that the first resource triggers the continuous LBT failure.
Alternatively, the consecutive LBT failure condition may be: the number of LBT failure events occurring on the first resource reaches a first number threshold. The first number threshold may be configured by the terminal device or the network device, and is not limited.
Optionally, the consecutive LBT failure condition may also be: the number of LBT failure events occurring on the first resource reaches a second number threshold and no LBT success event occurs within the first time period. Wherein, the first time period takes the moment when the number of times of the LBT failure events continuously occurring on the first resource reaches the second number threshold as the starting time point; the second number threshold may be configured by the terminal device or the network device, and is not limited. The LBT success event may refer to that the terminal device does not receive an LBT failure indication from a lower layer of the terminal device. This condition may be implemented by a first timer and a first counter. When an LBT failure event occurs on the first resource, the first counter may perform an add operation; starting a first timer when the first counter reaches a second number threshold, terminating the first timer if an LBT success event occurs during the running of the first timer, and resetting the first counter, for example, setting the first counter to an initial value; if the first timer runs out of time, that is, no LBT success event occurs during the first timer running, the terminal device may determine that the first resource satisfies a continuous LBT failure condition.
Optionally, the consecutive LBT failure condition may also be: the number of LBT failure events occurring on the first resource reaches a third number threshold, and the interval between two adjacent LBT failure events is less than a second time period. The third number threshold may be configured by the terminal device or the network device, and is not limited; the second time period may also be configured by the terminal device or the network device. This condition may be implemented by a second timer and a second counter. When an LBT failure event occurs on the first resource for one time, the second counter may perform an addition operation, and start or restart the second timer; resetting the second counter when the second timer times out, e.g., setting the second counter to an initial value; when the second counter reaches the third number threshold, the terminal device may determine that the first resource satisfies the consecutive LBT failure condition.
It should be noted that the above three consecutive LBT failure conditions may be applicable to a carrier and also to a resource pool. The first quantity threshold corresponding to the carrier may be different from the first quantity threshold corresponding to the resource pool, the second quantity threshold corresponding to the carrier may be different from the second quantity threshold corresponding to the resource pool, and so on.
420. And carrying out carrier reselection or resource pool reselection.
After determining that the first resource meets the condition of continuous LBT failure, the terminal device may perform carrier reselection or resource pool reselection, wherein the reselected carrier or resource pool does not intersect with the resource triggering the continuous LBT failure; for example, the reselected carrier or resource pool is a carrier or resource pool that does not trigger the consecutive LBT failure, and a frequency range corresponding to the reselected carrier or resource pool does not intersect with a frequency range corresponding to the carrier or resource pool that triggers the consecutive LBT failure.
It should be noted that the carrier reselection or the resource pool reselection may be implemented in the form of resource reselection. For example, in the Mode2 resource allocation Mode, before the terminal device selects a resource, it needs to select a carrier and a resource pool; and the terminal equipment reselects the resources after determining that the first resources meet the continuous LBT failure condition, so as to realize the reselection of the carrier and the resource pool.
By the method, the terminal device can trigger the continuous LBT failure of the first resource under the condition that the first resource meets the continuous LBT failure condition, and further can perform carrier reselection or resource pool reselection.
