Description

   Method and device for eliminating resources   

The present invention belongs to the field of communication technology, and particularly relates to a method and a device for excluding resources.

In the related art, when selecting a resource, the network node UE effectively avoids resources that may conflict by monitoring resources reserved by other terminals. As shown in FIG. 1, the network node 1 (UE1) now needs to select resources in its own resource selection window. It needs to process its own sending sub-frame and other sub-frames in the monitoring sense window.

Processing methods in related technologies of 3GPP: Assume that UE1 needs to select resources and reserve N times according to period P1; for other sub-frames k that are not sent by UE1 itself, UE1 can monitor k, assuming that UE1 monitors UE2 at period P2 Occupying time-frequency resources D, when 100 <= P2 <= 1000, if the sub-frame k + P2 coincides with any of the sub-frames x, x + P1, ..., x + (N-1) * P1, then UE1 needs to exclude the time-frequency resource D on the sub-frame x; when 0 <P2 <100, change the above k + P2 into the resource reservation that UE2 may reserve multiple times in the UE1 resource selection window. This means that for a service period greater than or equal to 100ms, UE1 only considers the resources reserved by UE2 once; for a service period less than 100ms, UE1 considers multiple reservations made by UE2 within its own resource selection window.

For UE1's own sending sub-frame, in the case of single process, since UE1 cannot monitor sub-frame k, it needs to be assumed that other UEs may potentially occupy sub-frame k on any of the allowed service cycles. Resources, for any business cycle P allowed by the system, if the sub-frame k + P coincides with any of the sub-frames x, x + P1, ..., x + (N-1) * P1, UE1 needs to exclude the sub-frame Frame x; in the case of multiple processes, different processes of UE1 are allowed to select different sub-frames. This means that as long as it is a service cycle allowed by the system, UE1 only considers the resources reserved by potential other UEs at one time. However, no specific solution is given for how to avoid resources for processes that currently need to select resources when there are multiple processes.

In summary, the disadvantages of the processing methods in related technologies are:

(1) For the sending sub-frames of other nodes, it is considered that short-periods must be avoided multiple times in the resource selection window, but short-period sub-frames appearing anywhere in the listening window in related technologies must be avoided. It does not have timeliness. For example, a sub-frame occupied by a short period appears in the first 200ms of the 1s monitoring window but has not been sent subsequently. At this time, it is unnecessary to avoid the corresponding resource of the sub-frame, which leads to the waste.

(2) For the processing of sending its own sub-frames, only the resources reserved by other potential UEs are considered when avoiding the resources, which is unreasonable for the service cycle of less than 100ms (the service cycles currently allowed by 3GPP include 20ms and 50ms, etc. Short cycle). For example, for a service with a business cycle of 20ms, it may occur 5 times within 100ms of the maximum resource selection window, and only considering avoiding it once will significantly increase the chance of resource conflicts.

(3) In the case of multiple processes, different processes of UE1 are allowed to select different sub-frames. However, no specific plan is given for how the current process of selecting resources avoids resources.

An object of the present invention is to provide a method and an apparatus for excluding resources, which solves the problem of excluding unnecessary resources or excluding fewer resources when excluding resources for services with a service cycle of less than 100 ms in the related art.

In order to make the technical problems, technical solutions, and advantages of the present invention clearer, the following describes in detail with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 2, some embodiments of the present invention provide a method for resource exclusion, which is applied to a first network node. The method includes: Step 11: When triggering resource selection at a first target moment, if the first network node is in At least one second network node is monitored on the receiving sub-frame in the first monitoring window corresponding to the first target time to occupy resources with a service period less than L allowed by the system, and it is determined whether the second network node satisfies the first Set a condition; wherein the first preset condition is that any one of the subsequent M1 reserved resources of the second network node falls within the first resource selection window corresponding to the first target time; where M1 is positive An integer, L is a positive integer; step 12, when the second network node satisfies the first preset condition, according to each second network node, the resource is reserved for M2 times starting from the starting position of the first resource selection window Exclude resources; where M2 is a positive integer, and M2 is less than or equal to L divided by the business cycle of the second network node.

In some embodiments of the present invention, when the value of L divided by the service period of the second network node is greater than or equal to 2, M2 is not equal to 1. Preferably, the value of M2 is a rounding value of L divided by the service period of the second network node

Wherein, the value of M2 is specifically: when L is divided by the service period of the second network node as an integer, M2 is equal to the value of L divided by the service period of the second network node; and when L is divided by the second When the value of the business cycle of the network node is a decimal, M2 is the rounding of the decimal. For example, when L is divided by the business cycle of the second network node = 3.4, then M2 is equal to 3.

Specifically, L is the maximum delay allowed by the system, or L is another equivalent physical meaning, and according to the standardization of the target, L is equal to 100 ms. For the convenience of description, 100ms is used instead of L in the following descriptions.

Further, the method provided by some embodiments of the present invention further includes: Step 13: When the second network node does not satisfy the first preset condition, perform resources according to a subsequent reserved resource of each second network node. exclude.

The failure of the second network node to meet the first preset condition specifically means that all the reserved resources of the subsequent M1 reservation resources of the second network node have not fallen into the first resource selection window. Further, the subsequent first reserved resource of the second network node directly falls behind the first resource selection window, and the resource is excluded according to the subsequent first reservation of the second network node; or the second network The subsequent M1 reservation resources of the node all fall before the starting position of the first resource selection window (for example, they all fall into the first monitoring window). At this time, the resources are made according to the subsequent M1 reservation resource of the second network node. Excluded; but since the reserved resource is before the first resource selection window, it essentially does not affect the resource exclusion process.

Further, when the first network node selects resources based on the service cycle P1 and needs to reserve resources for subsequent N1 times, step 12 in some embodiments of the present invention includes: step 121, determining according to the service cycle of the second network node From the starting position of the first resource selection window, the sub-frames where the M2 reserved resources are respectively located, and the first frequency domain resource reserved on each sub-frame; step 122, the sub-message where the M2 reserved resources are located The frame is compared with all the sub-frames in the first preset sub-frame set; wherein the first preset sub-frame set is {sub-frame x1, sub-frame x1 + P1, ..., sub-frame Frame x1 + (N1-1) * P1}; the sub frame x1 is each sub frame in the first resource selection window, and N1 is an integer greater than or equal to 1; step 123, if the resource is reserved for M2 times There is a sub-frame that coincides with any one of the sub-frames in the first preset sub-frame set, and it is determined to exclude the first frequency domain resource on the sub-frame x1.

That is, in a case where the service period allowed by the system includes less than 100ms, for a second network node with a service period less than 100ms, M1 is a pre-configured value. The first network node currently needs to select resources and reserve N1 times according to the period P1. When the first network node selects resources, the processing of the receiving sub-frame of the first network node is as follows: The road node can listen to the information of other network nodes (generally referred to as the scheduling signaling SA) so as to learn the information about the business cycle, occupied resources, reserved resources and other information of other network nodes. If the first network node detects in the first monitoring window that the second network node occupies the frequency domain resource D (that is, the first frequency domain resource) on the sub-frame K with a service cycle of less than 100ms, and the second network node Any one of the subsequent M1 reserved resources of the road node falls into the first resource selection window. For any sub-frame x1 in the first resource selection window, it is counted from the starting point of the first resource selection window. , Check if the M2 reserved frequency domain resource D corresponding to the sub-frame k is in any of the sub-frames x1, the sub-frames x1 + P1, ..., the sub-frame x1 + (N1-1) * P1 The sub-frames overlap. If there is overlap, the first network node excludes the frequency domain resource D on the sub-frame x1 in its first resource selection window.

It should be noted that the significance of M1-1 is to control the number of unsuccessful receptions (that is, fault tolerance opportunities) before the first resource selection window. If it is received more than M1-1 times, it should be received but not received. It is considered that the network node is away or the channel environment is particularly poor, and the reservation situation of the network node is not considered when the resources are excluded. The value of M1 is pre-configured; for example, different service periods take the same M1 value, or different service periods take different M1 values.

The meaning of N1 is an estimated upper limit of the number of resource occupation cycles of the first network node that needs to select resources at present, that is, at least to ensure that the selected resources can occupy the N1 cycles periodically and will not occur with the currently excluded resources. conflict. The value of N1 may be related to the requirements of the high-level service package of the first network node, or it may be related to the value of the counter selected by the first network node, or it may be related to the current channel occupation situation, or it may be related to service priority. The order is related and is not specifically limited here.

For example, the system allows business cycles of 20ms, 50ms, 100ms, and 200ms. As shown in FIG. 3, it is assumed that M1 (20ms) = 3 and M1 (50ms) = 2. UE1 selects a resource in the resource selection window at time m, and occupies the resource 3 times with a period of 200 ms.

In its monitoring window, UE1 perceives the resources occupied by the four UEs in a short period of less than 100ms. UE2 reserves resources at 50ms, UE3 reserves resources at 50ms, UE4 reserves resources at 20ms, and UE5 reserves resources at 20ms. When UE1 excludes resources, it needs to exclude the resources occupied by other UEs (UE2, UE3, UE4, and UE5) on the sub-frame x in the resource selection window. If sub-frame x, sub-frame x + 200, sub-frame If frame x + 400 coincides with one of the sub-frames in the following sub-frame set, the reserved resource on sub-frame x is excluded; specifically, the sub-frame set is shown in FIG. 3, and the sub-frame set The resources reserved by UE2 and UE4 are not included, because any one of the M1 resources reserved after UE2 and UE4 does not fall into the resource selection window (not shown in the figure); this sub-frame set includes the resources reserved by UE3 The sub-frame where the resource is located is specifically the sub-frame where the resource is reserved 2 times from the start position m + 4 of the resource selection window. It should be noted that if the resource selection window is relatively small, the resources for the two reservations may not completely fall into the resource selection window. The set of sub-frames also includes the sub-frames where the resources reserved by the UE5 are, specifically, the sub-frames where the resources are reserved 5 times from the start position m + 4 of the resource selection window. It should be noted that if the resource selection window is relatively small, the resources for the 5 reservations may not completely fall into the resource selection window.

Similarly, for a long period greater than or equal to 100 ms, the resource elimination process is the same as the related technology, and is not specifically limited here.

In summary, in some embodiments of the present invention, when a network node performs resource selection, for other network nodes monitored in the monitoring window that occupy resources with a service period of less than 100ms, if the other network nodes make subsequent M1 reservations Any time a resource is reserved in the resource selection window, the network node needs to consider other network nodes M2 reserved resources starting from the starting point of the resource selection window when the resource is excluded; M2 is equal to 100ms divided by the second network Rounding the value of the node's business cycle; this method can not only avoid the subsequent situation of not occupying resources due to network node disconnection or poor channel environment, and improve the timeliness of resource exclusion; it can also reduce the short cycle of less than 100ms Consider booking resources multiple times to reduce the chance of resource conflicts.

In order to better achieve the foregoing objective, as shown in FIG. 4, some embodiments of the present invention further provide a resource exclusion device, which is applied to a first network node. The device includes a first judgment module 21 for When resource selection is triggered at a target time, if the first network node listens to at least one second network node on a receiving sub-frame in the first monitoring window corresponding to the first target time, the system allows a service cycle less than L Occupy resources to determine whether the second network node meets a first preset condition; wherein the first preset condition is that any one of the subsequent M1 reservation resources of the second network node falls into the first target In the first resource selection window corresponding to the time; where M1 is a positive integer and L is a positive integer; a first exclusion module 22 is used when the second network node meets the first preset condition, according to each The second network node excludes resources from the M2 reserved resources starting from the starting position of the first resource selection window; where M2 is a positive integer and M2 is less than or equal to L divided by the business cycle of the second network node.

Specifically, in some embodiments of the present invention, when the value of L divided by the service period of the second network node is greater than or equal to 2, M2 is not equal to 1.

Specifically, in some embodiments of the present invention, the value of M2 is a rounding value of L divided by the service period of the second network node.

The first exclusion submodule is used if the sub-frame where the M2 reserved resource is located coincides with any one of the sub-frames in the first preset sub-frame set. The sub-frame, to determine to exclude the first frequency domain resource on the sub-frame x1.

In summary, in some embodiments of the present invention, when a network node performs resource selection, for other network nodes monitored in the listening window and occupying resources with a service cycle of less than 100ms, if the other network nodes make subsequent M1 reservations Any time a resource is reserved in the resource selection window, the network node needs to consider other network nodes M2 reserved resources starting from the starting point of the resource selection window when the resource is excluded; M2 is equal to 100ms divided by the second network Rounding the value of the node's business cycle; this method can not only avoid the subsequent situation of not occupying resources due to network node disconnection or poor channel environment, and improve the timeliness of resource exclusion; it can also reduce the short cycle of less than 100ms Consider booking resources multiple times to reduce the chance of resource conflicts.

It should be noted that the resource exclusion device provided by some embodiments of the present invention is a device corresponding to the above-mentioned resource exclusion method, then all embodiments of the above-mentioned resource exclusion method are applicable to the resource exclusion device, and all can reach the same or similar Beneficial effects.

As shown in FIG. 6, some embodiments of the present invention provide a method for excluding resources, which is applied to a first network node. The method includes: Step 41: When resource selection is triggered at a first target time, obtain a resource corresponding to the first target time. The last sending sub-frame in the first monitoring window; step 42, determining whether the last sending sub-frame in the first monitoring window reserves resources reserved by the system for each service cycle less than L and meets the second preset condition ; Wherein, the second preset condition is that the last sending sub-frame falls into the first target time with any one of the subsequent M3 sub-frames that are reserved for each service cycle that is less than L and is reserved by the system. Within the corresponding first resource selection window; where M3 is a positive integer and L is a positive integer; step 43, when the last sending sub-frame is reserved by the system and the resource reserved for each service cycle less than L satisfies the second preset When setting conditions, according to the last sending sub-frame, M4 reservation sub-frames starting from the starting position of the first resource selection window and reserved for each business cycle less than L allowed by the system The message frame excludes resources; M4 is a positive integer, and M4 is less than or equal to L divided by the business cycle allowed by the system and less than L.

In some embodiments of the present invention, when the value of L divided by the service period less than L allowed by the system is greater than or equal to 2, M4 is not equal to 1. Preferably, the value of M4 is a rounding of the value of L divided by the value of the service cycle that is less than L allowed by the system.

Specifically, L is the maximum delay allowed by the system, and according to the standardization of the target, L is equal to 100 ms. For the convenience of description, 100ms is used instead of L in the following descriptions.

Among them, the value of M4 is specifically: when 100ms divided by the system is less than 100ms business cycle value is an integer, M4 is equal to 100ms divided by the system is less than 100ms business cycle value; and when 100ms divided by the system is allowed When the value of the business cycle of less than 100ms is a decimal, M4 is the rounding of the decimal. For example, when 100ms divided by the business cycle of the system that is less than 100ms = 3.4, then M4 is equal to 3.

For the last sending sub-frame, it is necessary to select resources only after releasing the sending sub-frame. For the last sending sub-frame occupied by the first network node's listening window but already released, due to the first network The way node cannot receive on the sending sub-frame, it needs to be assumed that other network nodes may occupy any frequency-domain resources on the sending sub-frame with any period allowed by the system. When performing resource exclusion, all frequency-domain resources in the sub-frame that coincide with it in the resource selection window need to be excluded.

Further, the method provided by some embodiments of the present invention further includes: Step 44: When the last sending sub-frame with a resource reserved by the system for each service cycle less than L does not satisfy the second preset condition, according to The last sending sub-frame uses the reserved sub-frame reserved by the system for each service cycle less than L to exclude resources.

Wherein, the last sending sub-frame with the system reserved for each service cycle less than 100ms does not meet the second preset condition. Specifically, the last sending sub-frame with the system allows each business cycle of less than 100ms. All subsequent appointment sub-frames of the M3 appointment sub-frames following the appointment have not fallen into the first resource selection window. Further, the first reserved resource of the last sending sub-frame may only fall into the first resource selection window to the rear, and the resource is excluded according to the first reserved resource of the last sending sub-frame; or finally Subsequent M3 reservation resources of a sending sub-frame all fall before the starting position of the first resource selection window (for example, they all fall into the first monitoring window). At this time, according to the M3 times of the last sending sub-frame, The reserved resource is excluded from the resource; however, since the reserved resource is before the first resource selection window, the reserved resource does not substantially affect the process of resource exclusion.

Further, when the first network node selects a resource with a service cycle P2 and needs to reserve resources for subsequent N2 times, step 43 in some embodiments of the present invention includes: step 431, according to each service allowed by the system that is less than L Period, determine the M4 reserved sub-frames of the last sending sub-frame reservation starting from the starting position of the first resource selection window; step 432, set the M4 reserved sub-frames and the second preset sub-frame All the sub-frames in the frame are compared one by one; wherein the second preset sub-frame set is {sub-frame x2, sub-frame x2 + P2, ..., sub-frame x2 + (N2-1) * P2 }; The sub-frame x2 is each sub-frame in the first resource selection window, and N2 is an integer greater than or equal to 1. Step 433, if the M4 reserved sub-frames exist and the second preset If any one of the sub-frames in the sub-frame set coincides with the sub-frame, determine to exclude the sub-frame x2.

That is, in a case where the service period allowed by the system includes less than 100ms, for a second network node with a service period less than 100ms, M3 is a pre-configured value. The first network node currently needs to select resources and make reservations N2 times according to the period P2. When the first network node selects resources, the processing of the sub frame sent by the first network node is as follows: Assume that a network node takes less than 100ms The service cycle of the network occupies any frequency domain resource on the sub-frame k, and any one of the reserved resources of the network node M3 reservation resources falls into the resource selection window of the first network node. Any sub-frame x2 of the resource selection window of the network node is counted from the starting point of the resource selection window, and checks whether the sub-frame of the reserved resource corresponding to M4 times corresponding to the sub-frame k is x2, x2 + P2, …, X2 + (N2-1) * P2 coincides with any of the sub-frames. If there is an overlap, the first network node excludes the sub-frame x2 from its own resource selection window.

It should be noted that the significance of M3-1 is to control the number of unsuccessful receptions (that is, fault tolerance opportunities) before the first resource selection window. If more than M3-1 times should have been received but not received, it can be highly probable. It is considered that the network node is away or the channel environment is particularly poor, and the reservation situation of the network node is not considered when the resources are excluded. The value of M3 is pre-configured; for example, the same M3 value is used for different service cycles, or different M3 values are used for different service cycles.

The meaning of N2 is an estimated upper limit of the number of resource occupation cycles of the first network node that needs to select resources currently, that is, at least to ensure that the selected resources can occupy the N2 cycles periodically and will not occur with the currently excluded resources. conflict. The value of N2 may be related to the requirements of the high-level service package of the first network node, or it may be related to the value of the counter selected by the first network node, or it may be related to the current channel occupancy situation, or it may be related to service priority. The order is related and is not specifically limited here.

For example, the system allows business cycles of 20ms, 50ms, 100ms, and 200ms. As shown in FIG. 3, it is assumed that M3 (20ms) = 3 and M3 (50ms) = 2. UE1 selects a resource in the resource selection window at time m, and occupies the resource 3 times with a period of 200 ms.

As shown in FIG. 7, UE1 occupies the sub-frame k (the last sending sub-frame) for transmission. Therefore, UE1 cannot receive on the sub-frame k. Therefore, when UE1 selects resources, it is assumed that there are other sub-frames k. The UE occupies any resources at any period allowed by the system (20ms, 50ms, 100ms, 200ms). When UE1 selects resources, it needs to exclude all frequency domain resources on the sub-frame x in the sub-frame resource selection window. If the frame x, the sub frame x + 200, x + 400 and a certain sub frame in a sub frame set overlap, the sub frame set includes a sub frame k reserved from a resource selection period of 20ms. The starting position of the window is 5 sub-frames after the time of m + 4; it should be noted that if the resource selection window is relatively small, the resources reserved for the 5 times may not completely fall into the resource selection window. The set of sub-frames also includes two sub-frames from the starting position m + 4 of the resource selection window reserved for the sub-frame k with a period of 50ms. It should be noted that if the resource selection window is relatively small, these two times The reserved resources may not completely fall into the resource selection window.

Similarly, for a long period greater than or equal to 100 ms, the resource elimination process is the same as the related technology, and is not specifically limited here.

In summary, in some embodiments of the present invention, when a network node performs resource selection, for a sending sub-frame in a listening window, since it cannot monitor information, it is preset that any network node can use any system allowed by the system. Periodically occupying any frequency domain resources of the sub-frame, and corresponding resource exclusion shall exclude all frequency-domain resources on the sub-frame that coincide with the M4 reserved resources reserved for the short period of less than 100ms respectively. And M4 is equal to 100ms divided by the system's rounded value of the business cycle less than 100ms; this method can not only avoid the subsequent situation of not occupying resources due to network node disconnection or poor channel environment, and improve the timeliness of resource exclusion It can also consider multiple reservations of resources for short periods of less than 100ms, reducing the chance of resource conflicts.

In order to better achieve the foregoing objective, as shown in FIG. 8, some embodiments of the present invention further provide a resource exclusion device, which is applied to a first network node. The device includes: a first acquisition module 51 for When resource selection is triggered at a target time, the last sending sub-frame in the first monitoring window corresponding to the first target time is obtained; the second determining module 52 is configured to determine the last sending sub-frame in the first monitoring window Whether the resource reserved for each service cycle less than L allowed by the system meets a second preset condition; wherein the second preset condition is that the last sending sub-frame is reserved for each service cycle less than L allowed by the system Any of the following M3 appointment sub-frames of the appointment fall into the first resource selection window corresponding to the first target time; where M3 is a positive integer and L is a positive integer; the third exclusion module 53 uses When the resource sent by the last sending sub-frame with each service period less than L allowed by the system meets the second preset condition, according to the last sending sub-frame with each system less than L allowed by the system M4 reserved sub-frames from the start position of the first resource selection window for each business cycle reservation for resource exclusion; where M4 is a positive integer and M4 is less than or equal to L divided by the business cycle less than L allowed by the system .

Specifically, in some embodiments of the present invention, when the value of L divided by the service period less than L allowed by the system is greater than or equal to 2, M4 is not equal to 1.

Specifically, in some embodiments of the present invention, the value of M4 is a rounding value of L divided by a value of a service period less than L allowed by the system.

Specifically, in some embodiments of the present invention, the device further includes: a fourth exclusion module, configured to: when the last sending sub-frame is reserved by the system for each service cycle that is less than L and does not meet the second pre- When setting conditions, resource exclusion is performed according to the last sending sub-frame with one reserved sub-frame reserved for each business cycle less than L allowed by the system.

Specifically, in some embodiments of the present invention, the third exclusion module 53 includes: a second determination sub-module, configured to determine a starting position of the selection window from the first resource according to each service cycle allowed by the system that is less than L The first M4 reserved sub-frame for the last sending sub-frame reservation is started; the second comparison sub-module is used when the first network node selects a resource with the business cycle P2 and needs to reserve the resources for the subsequent N2 times, Compare the M4 reserved sub-frames with all the sub-frames in the second preset sub-frame set; wherein the second preset sub-frame set is {sub-frame x2, sub-frame x2 + P2, ..., sub-frame x2 + (N2-1) * P2}; the sub-frame x2 is each sub-frame in the first resource selection window, and N2 is an integer greater than or equal to 1; the second The exclusion sub-module is used to determine the exclusion sub-frame x2 if a sub-frame that coincides with any one of the sub-frames in the second preset sub-frame set exists in the M4 reserved sub-frames.

In summary, in some embodiments of the present invention, when a network node performs resource selection, for a sending sub-frame in a listening window, since it cannot monitor information, it is preset that any network node can use any system allowed by the system. Periodically occupy any frequency domain resource of the sub-frame, and corresponding resource exclusion shall exclude all frequency-domain resources on the sub-frame that coincide with the M4 reserved resources reserved for the short period of less than L respectively. And M4 is equal to L divided by the system's rounded value of the business cycle less than L; this method can not only avoid the subsequent situation of not occupying resources due to network node disconnection or poor channel environment, and improve the timeliness of resource exclusion It can also consider multiple reservations of resources for short periods less than L, reducing the chance of resource conflicts.

It should be noted that the resource exclusion device provided by some embodiments of the present invention is a device corresponding to the above-mentioned resource exclusion method, then all embodiments of the above-mentioned resource exclusion method are applicable to the resource exclusion device, and all can reach the same or similar Beneficial effects.

As shown in FIG. 9, some embodiments of the present invention further provide a resource exclusion method, which is applied to a first network node. The first network node includes at least one first business process of selected resources and at least one unselected resource. The second service process, the resource selected by the first network node for the first service process is the target frequency domain resource on the target sub-frame, the method includes: step 71, triggering the resource of the second service process at the second target time When selecting, it is determined whether the target sub-frame is the last sending sub-frame in the second monitoring window corresponding to the second target time; step 72, when the target sub-frame is the last sending sub-frame in the second monitoring window At that time, resources are excluded according to the target sub-frame with M5 reserved sub-frames reserved for all business cycles allowed by the system; where M5 is an integer greater than or equal to 1.

In some embodiments of the present invention, since the first network node cannot receive on the sending sub-frame, it needs to be assumed that other network nodes may occupy any frequency-domain resources on the sending sub-frame with any period allowed by the system. When performing resource exclusion, all frequency-domain resources in the sub-frame that coincide with it in the resource selection window need to be excluded.

Specifically, step 72 in some embodiments of the present invention includes: Step 721, when the target sub-frame is reserved with any of the subsequent M6 sub-frames that are reserved for a service cycle less than L that the system allows, the sub-frame is reserved. Into the second resource selection window, resources are excluded according to the target sub-frame with M5 reserved sub-frames starting from the starting position of the second resource selection window and reserved by the system for a business cycle less than L. Among them, M6 is A positive integer, and M5 is greater than 1 and less than or equal to L divided by the business cycle allowed by the system and less than L. L is a positive integer.

Among them, when the value of L divided by the service period less than L allowed by the system is greater than or equal to 2, M5 is not equal to 1. Preferably, the value of M5 is a rounding value of L divided by a value of a service period less than L allowed by the system.

Specifically, L is the maximum delay allowed by the system, and according to the standardization of the target, L is equal to 100 ms. For the convenience of description, 100ms is used instead of L in the following descriptions.

For example, when the value of 100ms divided by the system's business cycle less than 100ms is an integer, M5 is equal to the value of 100ms divided by the system's business cycle less than 100ms; and when 100ms divided by the system's business cycle less than 100ms When the value is a decimal, M5 is the rounding of the decimal. For example, when 100ms divided by the business cycle allowed by the system and less than 100ms = 3.4, then M5 is equal to 3.

Alternatively, in step 722, when the target sub-frame is reserved in the subsequent M6 reservation sub-frames with a business cycle less than L allowed by the system, none of them falls into the second resource selection window. M5 preset sub-frames reserved for service periods smaller than L are used to exclude resources; M5 is equal to 1.

Among them, when the target sub-frame is reserved for the subsequent M6 reserved sub-frames with a service cycle less than 100ms, the sub-frame does not fall into the second resource selection window, specifically: the first time the last sub-frame is sent The reserved resource may only fall into the first resource selection window to the rear, and the resource is excluded according to the first reserved resource of the last sending sub-frame; or the subsequent M5 reserved resources of the last sending sub-frame are all dropped. Before entering the starting position of the second resource selection window (for example, both fall into the second monitoring window), at this time, the resource is excluded according to the M5th reserved resource of the last sent sub-frame; however, because the reserved resource is at the first Prior to the second resource selection window, in essence, the reserved resources have no impact on the process of resource exclusion.

Alternatively, in step 723, resource exclusion is performed according to the target sub-frame using M5 reserved sub-frames for which the system allows a service cycle reservation greater than or equal to L; where M5 is equal to 1.

Further, for a short period of less than 100ms, the method for excluding resources is as follows: When the first network node selects a resource using the service period P3 as the second service process and needs to reserve resources for subsequent N3 times, step 721 includes: step 7211, According to each service cycle allowed by the system that is less than L, determine the M5 reserved sub-frames reserved for the target sub-frame after the target sub-frame; step 7212, the M5 reserved sub-frames and the third preset sub-frame are reserved. All the sub-frames in the frame set are compared one by one. The third preset sub-frame set is {sub-frame x3, sub-frame x3 + P3, ..., sub-frame x3 + (N3-1 ) * P3}; the sub-frame x3 is each sub-frame in the second resource selection window, and N3 is an integer greater than or equal to 1; step 7213, if the M5 sub-frames for sub-frames exist and the first Any one of the three sub-frames in the three preset sub-frame sets coincides with each other, and determines to exclude the sub-frame x3.

That is, when the allowed service cycle of the system is less than 100ms, M6 is a pre-configured value. The first network node currently needs to select resources according to the period P3 and make reservations N3 times. When the first network node selects the resources, the processing of the first sub-frame sent by the first network node is as follows: Assume that a network node takes less than 100ms Business cycle occupies any frequency domain resource on the sub-frame k, and any one of the network node's future M6 reservation resources falls into the second resource selection window, then for any one of the resource selection windows The sub-frame x3 is counted from the starting point of the resource selection window, and checks whether the sub-frame where the reserved resource corresponding to the sub-frame k corresponds to M5 times is the same as x3, x3 + P3, ..., x3 + (N3-1) * P3 Any one of the sub-frames coincides. If there is an overlap, the first network node excludes the sub-frame x3 in its own resource selection window.

It should be noted that the significance of M6-1 is to control the number of unsuccessful receptions (that is, fault tolerance opportunities) before the first resource selection window. If more than M6-1 times should have been received but not received, it can be highly probable. It is considered that the network node is away or the channel environment is particularly poor, and the reservation situation of the network node is not considered when the resources are excluded. The value of M6 is pre-configured; for example, different service periods take the same M6 value, or different service periods take different M6 values.

The meaning of N3 is an estimated upper limit of the number of resource occupation cycles of the first network node that currently needs to select resources, which means that at least the selected resources can be used for N3 cycles and will not occur with the currently excluded resources. conflict. The value of N3 may be related to the demand of the high-level service package of the first network node, or it may be related to the value of the counter selected by the first network node, or it may be related to the current channel occupancy situation, or it may be related to service priority. The order is related and is not specifically limited here.

Further, for a long period greater than or equal to L, the resource exclusion method is as follows: When the first network node selects a resource with the service period P4 as the second service process and needs to reserve resources for subsequent N4 times, step 723 includes: Step 7231. According to each service cycle allowed by the system that is greater than or equal to L, determine an appointment sub-frame for the target sub-frame reservation; step 7232, associate the 1 appointment sub-frame with a fourth preset sub-frame. All the sub-frames in the set are compared one by one; wherein the fourth preset sub-frame set is {sub-frame x4, sub-frame x4 + P4, ..., sub-frame x4 + (N4-1) * P4}; the sub-frame x4 is each sub-frame in the second resource selection window, and N4 is an integer greater than or equal to 1; step 7233, if the 1 sub-frame and the fourth preset sub-frame Any one of the sub-frames in the frame set overlaps, and the sub-frame x4 is determined to be excluded.

That is, in the case that the system allows a service cycle that is greater than or equal to 100ms, the first network node currently needs to select resources and reserve N4 times according to the cycle P4. When the first network node selects resources, the first network node The process of sending a sub-frame is as follows: Assume that a network node occupies any frequency-domain resource on the sub-frame k with a service period greater than or equal to 100 ms. For any resource in the window of the first network node's resource selection window, Box x4, check whether the sub-frame corresponding to the next reserved resource corresponding to sub-frame k coincides with any of the sub-frames x4, x4 + P4, ..., x4 + (N4-1) * P4. A network node excludes child frame x4 in its resource selection window.

It should be noted that the meaning of N4 is that the first network node that currently needs to select a resource has an estimated upper limit on the number of resource occupation cycles to be selected, which means that at least the selected resources can be used for N4 cycles and will not Excluded resources conflict. The value of N4 may be related to the requirements of the high-level service package of the first network node, or it may be related to the value of the counter selected by the first network node, or it may be related to the current channel occupancy situation, or it may be related to service priority. The order is related and is not specifically limited here.

Further, since the first service process of the first network node has selected the target frequency domain resources of the target sub-frame, at this time, when selecting resources for the second service process, the actual reserved resources of the first service process need to be considered. Specifically, after step 72, the method further includes: step 73, performing resource exclusion according to the remaining reserved resources after the target sub-frame of the first service process.

Specifically, when the first network node selects a resource using the service cycle P5 as the second service process and needs to reserve resources for subsequent N5 times, step 73 includes: Step 731, determining the target sub message according to the service cycle of the first service process. The sub-frames where the remaining reserved resources after the frame are respectively located, and the target frequency domain resources reserved on each sub-frame; step 732, the sub-frames where the remaining reserved resources are respectively located with the fifth preset sub-frame. All the sub-frames in the frame are compared one by one. The fifth preset sub-frame set is {sub-frame x5, sub-frame x5 + P5, ..., sub-frame x5 + (N5-1) * P5 }; The sub-frame x5 is each sub-frame in the second resource selection window, and N5 is an integer greater than or equal to 1; step 733, if the sub-frame where the remaining reserved resource exists and the fifth Preset a sub-frame in which any one of the sub-frames coincides with the preset sub-frame set, and determine to exclude the target frequency domain resource on the sub-frame x5, or determine to exclude the sub-frame x5.

That is, for any sub-frame x5 of the second resource selection window, counting from the starting position of the resource selection window of the second business process of the first network node, checking the actual status of the first business process of the first network node Whether the reserved resources of the sub-frame coincide with any of the sub-frame x5, sub-frame x5 + P5, ..., sub-frame x5 + (N5-1) * P5, if there is any overlap, the first network node Exclude the target frequency domain resources on the sub-frame x5 in your own resource selection window or determine to exclude the sub-frame x5.

It should be noted that the significance of N5 is that the first network node that currently needs to select a resource has an estimated upper limit on the number of resource occupation cycles to be selected, which means that at least the selected resource can be used for N5 cycles at a time. Excluded resources conflict. The value of N5 may be related to the requirements of the high-level service package of the first network node, or it may be related to the value of the counter selected by the first network node, or it may be related to the current channel occupation situation, or it may be related to service priority. The order is related and is not specifically limited here.

Furthermore, when the target sub-frame is the last sending sub-frame in the second monitoring window, the method provided by some embodiments of the present invention further includes: Step 74, determining whether the target sub-frame is the second monitoring window. Step 75: If the target sub-frame is not the last transmission opportunity in the second monitoring window, further exclude resources based on the information monitored in the second monitoring window.

That is, if the target sub-frame is the last sending opportunity in the second monitoring window, the resource exclusion method includes resource exclusion for the sending sub-frame and resource exclusion for the remaining reserved resources of the first business process; and when the target sub-frame The frame is not the last transmission opportunity in the second monitoring window (that is, after the target sub-frame, there are one or more transmission opportunities in the second monitoring window. The transmission opportunity means that it should have been sent on the sub-frame but was not sent. Situation), at this time, the one or more sending opportunities can monitor the information of other network nodes, so as to determine the specific occupation of other network nodes.

Specifically, step 75 includes: Step 751, if at least one second network node is monitored on the receiving sub-frame in the second monitoring window to occupy resources with a service cycle of less than 100ms, determine whether the second network node meets the first A preset condition; wherein the first preset condition is that any one of the subsequent M1 reserved resources of the second network node falls into the second resource selection window corresponding to the first target time; wherein M1 Is a positive integer, and L is a positive integer.

The value of M2 is specifically: when 100ms divided by the service period of the second network node is an integer, M2 is equal to 100ms divided by the value of the service period of the second network node; and when 100ms is divided by the second network node When the value of the business cycle of the network node is a decimal, M2 is the rounding of the decimal. For example, when 100ms divided by the business cycle of the second network node = 3.4, M2 is equal to 3.

Step 752, when the second network node meets the first preset condition, resource exclusion is performed according to M2 reserved resources of each second network node starting from the starting position of the second resource selection window; where M2 Is a positive integer, and M2 is less than or equal to L divided by the business cycle of the second network node.

Step 753: When the second network node does not satisfy the first preset condition, perform resource exclusion according to a subsequent reserved resource of each second network node.

Wherein, when the value of L divided by the service period of the second network node is greater than or equal to 2, M2 is not equal to 1. Preferably, the value of M2 is a rounding value of L divided by the service period of the second network node. When the second network node makes a reservation for the subsequent M1 reservation sub-frames with a service cycle less than L, the system does not fall into the second resource selection window, specifically: the first reservation of the last sending sub-frame The resource may only fall into the first resource selection window to the rear, and the resource is excluded according to the first reserved resource of the last sending sub-frame; or the subsequent M1 reserved resources of the last sending sub-frame are all included. Before the starting position of the second resource selection window (for example, both fall into the second monitoring window), the resource is excluded according to the M1th reserved resource of the last sent sub-frame; however, because the reserved resource is in the second Prior to the resource selection window, essentially the reserved resources have no effect on the process of resource exclusion.

Further, for a short period less than L, its resource exclusion method is as follows: When the first network node selects a resource with the service period P6 as the second service process and needs to reserve resources for subsequent N6 times, step 752 includes: step 7521, According to the service cycle of the second network node, determine the M2 sub-frame where the reserved resource is located after the target sub-frame and the second frequency domain resource reserved on each sub-frame; step 7522, the M2 times The sub-frame where the reserved resource is located is compared with all the sub-frames in the sixth preset sub-frame set; wherein the sixth preset sub-frame set is {sub-frame x6, sub-frame x6 + P6, ..., sub frame x6 + (N6-1) * P6}; the sub frame x6 is each sub frame in the second resource selection window, and N6 is an integer greater than or equal to 1; step 7523, If there is a sub-frame that coincides with any one of the sub-frames in the sixth preset sub-frame set, the second frequency-domain resource on the sub-frame x6 is determined to be excluded if the sub-frame where the M2 reserved resource is located.

That is, in a case where the service period allowed by the system includes less than 100ms, for a second network node with a service period less than 100ms, M1 is a pre-configured value. The first network node currently needs to select resources and reserve N6 times according to the period P6. When the first network node selects resources, the processing of the receiving sub-frame of the first network node is as follows: The road node can listen to the information of other network nodes (generally referred to as the scheduling signaling SA) so as to learn the information about the business cycle, occupied resources, reserved resources and other information of other network nodes. If the first network node detects in the first monitoring window that the second network node occupies the frequency domain resource D (that is, the first frequency domain resource) on the sub-frame K with a service cycle of less than 100ms, and the second network node Any one of the resources reserved for the subsequent M1 reservations of the road node falls into the first resource selection window. For any sub-frame x6 in the first resource selection window, it starts from the starting point of the first resource selection window. , Check whether the M2 reserved frequency domain resource D corresponding to the sub-frame k is in any of the sub-frame x6, the sub-frame x6 + P6, ..., the sub-frame x6 + (N6-1) * P6 The sub-frames overlap. If there is overlap, the first network node excludes the frequency domain resource D on the sub-frame x6 in its first resource selection window.

It should be noted that the significance of M1-1 is to control the number of unsuccessful receptions (that is, fault tolerance opportunities) before the first resource selection window. If it is received more than M1-1 times, it should be received but not received. It is considered that the network node is away or the channel environment is particularly poor, and the reservation situation of the network node is not considered when the resources are excluded. The value of M1 is pre-configured; for example, the same M1 value is used for different service cycles, or different M3 values are used for different service cycles.

The significance of N6 is that the first network node that currently needs to select a resource has an estimated upper limit on the number of resource occupation cycles to be selected, which means that at least the selected resources can be used for N6 cycles and will not occur with the currently excluded resources. conflict. The value of N6 may be related to the requirements of the high-level service package of the first network node, or it may be related to the value of the counter selected by the first network node, or it may be related to the current channel occupancy situation, or it may be related to service priority. The order is related and is not specifically limited here.

Further, for a long period greater than or equal to L, the resource exclusion method is as follows: Step 75 further includes: Step 753, if at least one third network node is monitored on the receiving sub-frame in the second monitoring window with a value greater than or A business cycle equal to L occupies resources, and resources are excluded according to a subsequent reserved resource of each third network node.

And when the first network node selects a resource using the service cycle P7 as the second service process and needs to reserve resources for subsequent N7 times, step 753 includes: step 7531, determining the third network according to the service cycle of the third network node The subsequent sub-frame where the road node reserves resources next time and the third frequency domain resource reserved on the sub-frame; step 7532, set the sub-frame where the once reserved resource is located with the seventh preset sub-frame All the sub-frames in the frame are compared one by one; the seventh preset sub-frame set is {sub-frame x7, sub-frame x7 + P7, ..., sub-frame x7 + (N7-1) * P7 }; The sub-frame x7 is each sub-frame in the second resource selection window, and N7 is an integer greater than or equal to 1; step 7533, if the sub-frame where the resource is reserved once and the seventh preset Any one of the sub-frames in the sub-frame set overlaps, and it is determined to exclude the third frequency domain resource on the sub-frame x7.

That is, in the case that the system allows a service cycle that is greater than or equal to 100ms, the first network node currently needs to select resources and reserve N7 times according to the cycle P7. When the first network node selects resources, the first network node The processing of the receiving sub-frame is as follows: The first network node in the receiving sub-frame can listen to the information of other network nodes (generally referred to as the scheduling signaling SA) to learn the business cycle, occupied resources, and reserved resources of other network nodes. And other information. If the first network node detects within the first monitoring window that the third network node occupies the frequency domain resource D (that is, the third frequency domain resource) on the sub-frame K with a service period greater than or equal to 100 ms, Any one of the sub-frames x1 in a resource selection window, and check whether the sub-frame of the subsequent reservation frequency domain resource D of the sub-frame k is in the same sub-frame x7, the sub-frame x7 + P7, ..., the sub-frame x7 + (N7-1) * Any of the sub-frames in P7 overlap. If there is any overlap, the first network node excludes the frequency domain resource D on the sub-frame x7 in its first resource selection window.

It should be noted that the significance of N7 is that the first network node that currently needs to select a resource has an estimated upper limit on the number of cycles to be selected by the resource, which means that at least the selected resource can be used for N7 cycles at a time. Excluded resources conflict. The value of N7 may be related to the requirements of the high-level service package of the first network node, or it may be related to the value of the counter selected by the first network node, or it may be related to the current channel occupancy situation, or it may be related to service priority. The order is related and is not specifically limited here.

For example, the system allows a service cycle of 20ms, 50ms, 100ms, 200ms, assuming M (20ms) = 3, M (50ms) = 2. UE1 should select a resource in the resource selection window of the second service process at time m, and occupy the resource 3 times with a period of 200 ms.

As shown in FIG. 10, it is assumed that the first network node has two business processes, and now it is the second business process to select resources. Assume that the first business process occupies sub-frame k (sub-frame k is the last sending sub-frame) for transmission, but hangs on sub-frame k + 20 (sub-frame k + 20 is the last sending opportunity) (That is, the first business process should have sent on the sub-frame k + 20 but it did not actually). The first network node can receive on the sub-frame k + 20 and found that other network nodes are on the sub-frame k +. If the frequency domain resource is occupied for a period of 50 ms on the network, the second service process of the first network node needs to exclude the frequency domain resource reserved on the sub frame x in the sub frame resource selection window when selecting the resource. If frame x, sub frame x + 200, x + 400 and a sub frame in a sub frame set overlap, the reserved resource on sub frame x is excluded.

Wherein, the set of sub-frames includes 8 sub-frames reserved by sub-frame k with a period of 20 ms, where 8 is the actual remaining number of reserved resources of the first business process of the first network node; the sub-frame set also Including the two sub-frames reserved by the sub-frame k with a period of 50ms, it should be noted that if the resource selection window is relatively small, the resources for the two reservations may not completely fall into the resource selection window.

In summary, in the method for excluding resources provided by some embodiments of the present invention, the first network node includes multiple service processes. When a second service process that does not select a resource selects a resource, it is necessary to consider the actual situation of other first service processes that have selected a resource. Reserved resources (specifically, the remaining first business process starting from the starting position of the resource selection window of the second business process is the actual reserved resource), so as to avoid collisions with the resources of the first business process and avoid network interruptions The subsequent situation of not occupying resources caused by open or bad channel environment improves the timeliness of resource exclusion.

In order to better achieve the foregoing objective, as shown in FIG. 11, some embodiments of the present invention further provide a resource exclusion device, which is applied to a first network node, where the first network node includes at least one first resource that has been selected. A business process and at least one second business process that does not select a resource, and the resource selected by the first network node for the first business process is a target frequency domain resource on a target subframe, and the device includes a third judgment module 81, When triggering the resource selection of the second business process at the second target time, determine whether the target sub-frame is the last sending sub-frame in the second listening window corresponding to the second target time; the fifth exclusion module 82, When the target sub-frame is the last sending sub-frame in the second monitoring window, resources are excluded according to the target sub-frame with M5 reserved sub-frames reserved for all business cycles allowed by the system; where M5 is An integer greater than or equal to 1, and L is a positive integer.

Specifically, in some embodiments of the present invention, when a value of L divided by a service period less than L allowed by the system is greater than or equal to 2, M5 is not equal to 1.

Specifically, in some embodiments of the present invention, the value of M5 is a rounding value of L divided by a value of a service period less than L allowed by the system.

Specifically, in some embodiments of the present invention, the fifth exclusion module includes: a third exclusion submodule, which is used to make subsequent M6 reservation sub-messages when the target sub-frame is reserved with a service cycle less than L allowed by the system If any one of the booking sub-frames in the frame falls into the second resource selection window, then according to the target sub-frame, the M5 reservation sub-messages starting from the starting position of the second resource selection window and reserved by the system with a business cycle less than L are allowed. Frame for resource exclusion; where M6 is a positive integer and M5 is greater than 1 and less than or equal to L divided by the business cycle allowed by the system and less than L; and / or, a fourth exclusion submodule is used as the target subframe Subsequent M6 reservation sub-frames that are reserved with a service period less than L allowed by the system do not fall into the second resource selection window. According to the target sub-frames, M5 reservations with a service period less than L allowed by the system Set a sub-frame for resource exclusion; where M5 is equal to 1; and / or, a fifth exclusion sub-module is used to make M5 reservation sub-messages that are reserved according to the target sub-frame with a business cycle that is greater than or equal to L Frame Excluded; wherein, M5 is equal to 1.
