Description

 Resource elimination method and device  

The invention belongs to the field of communication technologies, and in particular relates to a resource elimination method and device.

In the related art, the network node UE effectively avoids resources that may collide by listening to resources reserved by other terminals when selecting resources. As shown in Figure 1, Network Node 1 (UE1) now has to select resources in its own resource selection window. It needs to handle its own listening subframes and other subframes in the sensing window.

The processing method in the related art of 3GPP: It is assumed that UE1 needs to select resources according to period P1 and reserve N times; for other subframes k that are not UE1 to transmit subframes, UE1 can listen to k, and assume that UE1 listens to UE2 with period P2. Occupying the time-frequency resource D, when 100<=P2<=1000, if the subframe k+P2 coincides with any of the x, P+, ..., x+(N-1)*P1 subframes, then The UE1 needs to exclude the time-frequency resource D on the subframe x; when 0<P2<100, the above k+P2 becomes the resource reservation that the UE2 may reserve multiple times in the UE1 resource selection window. It means that for a service period greater than or equal to 100 ms, UE1 only considers the resources reserved by UE2 at one time; and for a service period less than 100 ms, UE1 considers multiple reservations of UE2 in its own resource selection window.

For UE1's own transmission subframe, in the case of single process, since UE1 cannot listen to subframe k, it is necessary to assume that there are potentially other UEs on subframe k occupying subframes k in any allowed service period. Resources, for any service period P allowed by the system, if the subframe k+P coincides with any of the sub-frames of 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 subframes. This means that as long as the service period allowed by the system, UE1 only considers the resources reserved by other UEs at one time. For a multi-process, no specific solution is given for how the process that currently needs to select a resource avoids resources.

In summary, the shortcomings of the processing methods in the related art are:

(1) For the transmitting subframes of other nodes, it is considered that the short period should be avoided multiple times in the resource selection window, but the short-cycle subframes appearing anywhere in the listening window in the related art should be avoided. It is not time-sensitive. For example, in the first 200 ms of the listening window of 1 s, the sub-frame occupied by the short period occurs but the subsequent sub-frames are not sent. In this case, it is unnecessary to avoid the resources corresponding to the sub-frame, resulting in resources. waste.

(2) For the processing of sending sub-frames by itself, only the resources reserved by other potential UEs are considered when avoiding resources, which is unreasonable for the service period less than 100ms (the service period allowed by 3GPP includes 20ms and 50ms. Short cycle). For example, for a service with a service period of 20ms, it may appear 5 times within 100ms of the largest resource selection window, and only consider avoiding the opportunity to significantly increase resource conflicts.

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

The technical problems, the technical solutions, and the advantages of the present invention will be more clearly described in the following description.

As shown in FIG. 2, some embodiments of the present invention provide a resource exclusion method, which is applied to a first network node, where the method includes: Step 11: When a resource selection is triggered at a first target moment, if the first network node is The receiving subframe in the first listening window corresponding to the first target moment monitors at least one second network node to occupy resources in a service period less than L allowed by the system, and determines whether the second network node satisfies the first pre- Setting a condition; wherein, the first preset condition is that any one of the M1 secondary reservation resources of the second network node falls within the first resource selection window corresponding to the first target time; wherein, 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, M2 reservation resources starting from a starting position of the first resource selection window Resource exclusion is performed; wherein M2 is a positive integer, and M2 is less than or equal to L divided by the service period of the second network node.

In some embodiments of the present invention, when the value of L divided by the traffic 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 of the value of L divided by the service period of the second network node.

The value of M2 is specifically, when L is divided by the value of the service period of the second network node, M2 is equal to L divided by the value of the service period of the second network node; and when L is divided by the second When the value of the service period of the network node is a decimal, M2 is a rounding of the decimal. For example, when L is divided by the service period 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 other equivalent physical meaning, and according to the standardization of the target, L is equal to 100 ms. For convenience of description, the subsequent description uses 100ms instead of L.

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

The second network node does not meet the first preset condition, and specifically: all the reserved resources in the M1 reserved resources of the second network node do not fall into the first resource selection window. Further, the first reserved resource of the second network node directly falls behind the first resource selection window, and the resource is excluded according to the first reservation of the second network node; or the second network The M1 secondary reservation resources of the node are all before the starting point of the first resource selection window (for example, all fall into the first listening window), and at this time, the resources are performed according to the M1 reserved resources subsequent to the second network node. Excluded; but since the reserved resource is in front of the first resource selection window, it substantially does not affect the process of resource exclusion.

Further, when the first network node selects the resource in the service period P1 and needs to reserve the resource of the subsequent N1 times, the step 12 in some embodiments of the present invention includes: Step 121, determining according to the service period of the second network node. a sub-frame where the M2 reservation resources are respectively located from the start position of the first resource selection window, and a first frequency domain resource reserved on each sub-frame; and step 122, the sub-message of the M2 reservation resource The frame is compared with all the subframes in the first preset subframe set; wherein the first preset subframe collection is {subframe x1, subframe x1+P1, ..., sub The frame x1+(N1-1)*P1}; the subframe x1 is each subframe in the first resource selection window, and N1 is an integer greater than or equal to 1; in step 123, if the M2 reservation resource The subframe in which the sub-frame is located overlaps with any one of the subframes in the first preset subframe set, and determines to exclude the first frequency domain resource on the subframe x1.

That is, in the case that the service period allowed by the system includes less than 100 ms, for the second network node whose service period is less than 100 ms, M1 is a pre-configured value. The first network node needs to select the resource according to the period P1 and reserve N1 times. When the first network node selects the resource, the processing of the receiving subframe of the first network node is as follows: receiving the first network in the subframe The road node can listen to information of other network nodes (generally, the scheduling signaling SA) to learn information about other network nodes' service periods, resources, and reserved resources. If the first network node detects, in the first listening window, that the second network node occupies the frequency domain resource D (ie, the first frequency domain resource) on the subframe K with a service period of less than 100 ms, and the second network If any of the resources reserved for the M1 reservations of the path node falls within the first resource selection window, then any subframe x1 in the first resource selection window is counted from the beginning of the first resource selection window. Check whether the sub-frame of the M2 times reserved frequency domain resource D corresponding to the subframe k is associated with any of the subframe x1, the subframe x1+P1, ..., the subframe x1+(N1-1)*P1. The sub-frames coincide, and if there is a coincidence, the first network node excludes the frequency domain resource D on the subframe x1 in its own first resource selection window.

It should be noted that the meaning of M1-1 is to control the number of times that the reception is unsuccessful before the first resource selection window (ie, the fault tolerance opportunity), and if it is received more than M1-1 times, it may be received without a high probability. It is considered that the network node is gone or the channel environment is particularly poor, and the reservation of the network node is not considered when the resource is 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 that the first network node that needs to select a resource currently has an estimated upper limit on the number of resource occupation periods to be selected, that is, at least that the selected resource can occupy N1 times periodically and does not occur with the currently excluded resources. conflict. The value of N1 may be related to the requirement of the high-level service packet of the first network node, or may be related to the value of the counter counter selected by the first network node, or may be related to the current channel occupancy status, or may be prioritized with the service. The order is related and is not specifically limited herein.

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

The UE1 perceives the resources occupied by the four UEs in a short period of less than 100 ms in its own listening window, and reserves resources for UE2 in 50 ms, UE3 reserves resources in 50 ms, UE4 reserves resources in 20 ms, and UE5 reserves resources in 20 ms. If the UE1 excludes resources, it is necessary to exclude resources reserved by other UEs (UE2, UE3, UE4, and UE5) in the subframe x in the resource selection window, if the subframe x, the subframe x+200, the sub-frame If the frame x+400 overlaps with one of the sub-frames in the following sub-frame set, the reserved resource on the sub-frame x is excluded; specifically, the sub-frame set is as shown in FIG. 3, and the sub-frame set is set. The resources reserved by the UE2 and the UE4 are not included, because any one of the reserved resources of the M1 resources reserved by the UE2 and the UE4 does not fall into the resource selection window (not shown); the subframe set includes the resources reserved by the UE3. The sub-frame is located in the sub-frame where the reserved resource is located twice from the start position of the resource selection window m+4. It should be noted that if the resource selection window is relatively small, the resources of the two reservations may not completely fall into the resource selection window. The sub-frame set further includes a sub-frame in which the resource reserved by the UE 5 is located, specifically, a subframe in which the reserved resource is located 5 times after the time m+4 from the start position of the resource selection window. It should be noted that if the resource selection window is relatively small, the resources of the five 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 art, and is not specifically limited herein.

In summary, in some embodiments of the present invention, when a network node performs resource selection, for other network nodes that are listening to resources in a listening window that consumes resources in a service period of less than 100 ms, if the other network node subsequently makes an M1 reservation If any of the resources in the resource is reserved in the resource selection window, the network node needs to reserve resources for other network nodes M2 from the beginning of the resource selection window when the resource is excluded; M2 is equal to 100ms divided by the second network. The value of the service period of the node is rounded off; the method can not only avoid the situation that the network node is disconnected or the channel environment is not good, and the resource is not occupied, and the time limit of resource exclusion is improved; and the short period of less than 100 ms can also be avoided. Consider multiple booking resources to reduce opportunities for resource conflicts.

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 invention, the value of M2 is a rounding of the value of L divided by the traffic period of the second network node.

It should be noted that, the resource exclusion device provided by some embodiments of the present invention is a device corresponding to the foregoing resource exclusion method, and all embodiments of the resource exclusion method are applicable to the resource exclusion device, and both can achieve the same or similar The benefits.

As shown in FIG. 6 , some embodiments of the present invention provide a resource exclusion method, which is applied to a first network node, where the method includes: Step 41: When triggering resource selection at a first target moment, acquiring a first target moment The last one of the first listening window sends a subframe; in step 42, it is determined whether the last one of the first listening frames in the first listening window meets the second preset condition for the resource reserved for each service period less than L allowed by the system. The second preset condition is that the last one of the sub-frames in the last M3 reservation sub-frames reserved for each service period that is allowed by the system is less than L, and the one of the reserved sub-frames falls into the first target moment. Corresponding to the first resource selection window; wherein, M3 is a positive integer, and L is a positive integer; and in step 43, when the last transmission subframe is reserved by the system for each service period that is less than L, the resource is satisfied. When the condition is set, the M4 reservations from the starting position of the first resource selection window, which are reserved for each business cycle of the system allowed less than L, according to the last transmission subframe. Negative resource block; wherein, M4 is a positive integer less than or equal to L and M4 allows less than L divided by the business cycle.

In some embodiments of the invention, M4 is not equal to 1 when L is divided by the value of the service period allowed by the system that is less than L. Preferably, the value of M4 is rounded by dividing L by the value of the service period allowed by the system that is less than L.

Specifically, L is the maximum delay allowed by the system, and according to the standardization situation of the target, L is equal to 100 ms. For convenience of description, the subsequent description uses 100ms instead of L.

The value of M4 is specifically: when 100ms is divided by the value of the service period allowed by the system to be less than 100ms, the value of M4 is equal to 100ms divided by the value of the service period allowed by the system less than 100ms; and when 100ms is divided by the system, When the value of the service period less than 100 ms is a decimal, M4 is a rounding of the decimal, for example, 100 ms divided by the service period of less than 100 ms allowed by the system = 3.4, then M4 is equal to 3.

For the last transmission subframe, it is necessary to release the transmission subframe to select the resource, and the last transmission subframe that is occupied but already released in the listening window of the first network node is due to the first network. The path node cannot be received on the transmitting subframe, and it is assumed that other network nodes may occupy any frequency domain resources on the transmitting subframe in any period allowed by the system. All resource domain resources of the sub-frames in the resource selection window must be excluded when performing resource exclusion.

Further, the method provided by some embodiments of the present invention further includes: Step 44, when the last one of the transmission subframes is reserved by the system for each resource period that is less than L, and the resource is not satisfied by the second preset condition, according to The last one sent subframe is used for resource exclusion in a reserved subframe that is reserved by the system for each service period less than L.

The last one of the transmission subframes that is reserved by the system for each service period of less than 100 ms does not satisfy the second preset condition, and the last one of the transmission subframes is allowed by the system for each service period of less than 100 ms. All the reserved sub-frames in the subsequent M3 reservation sub-frames of the reservation do not fall within the first resource selection window. Further, the first reserved resource of the last transmission subframe may only fall into the first resource selection window, and the resource is excluded according to the first reserved resource of the last transmission subframe; or finally The M3 reservation resources subsequent to a transmission subframe fall before the start position of the first resource selection window (for example, all fall into the first listening window), and then according to the M3th of the last transmission subframe The resource is reserved for resource exclusion; however, since the reserved resource is in front of the first resource selection window, it substantially does not affect the process of resource exclusion.

Further, when the first network node selects the resource in the service period P2 and needs to reserve the resource of the subsequent N2 times, the step 43 in some embodiments of the present invention includes: Step 431, according to each service less than L allowed by the system. a period of determining the M4 reservation subframes of the last transmission subframe reservation starting from the starting position of the first resource selection window; step 432, the M4 reservation subframes and the second preset subframe collection All the sub-frames in the comparison 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 reservation sub-frame exists and the second preset The sub-frames of any one of the subframes in the subframe set are determined to exclude the subframe x2.

That is, in the case that the service period allowed by the system includes less than 100 ms, for the second network node whose service period is less than 100 ms, M3 is a pre-configured value. The first network node needs to select resources according to the period P2 and reserve N2 times. When the first network node selects resources, the processing of the sending subframe of the first network node is as follows: Suppose a network node is less than 100 ms. The service cycle occupies any frequency domain resource on the subframe k, and the network node falls into the resource selection window of the first network node any time in the M3 reservation resource, and then the first Any sub-frame x2 of the resource selection window of the network node is counted from the beginning of the resource selection window, and checks whether the sub-frame of the M4 reserved resource corresponding to the subframe k is associated with x2, x2+P2, ..., x2+(N2-1)*P2 any of the sub-frames coincide, if there is a coincidence, the first network node excludes the sub-frame x2 in its own resource selection window.

It should be noted that the meaning of M3-1 is to control the number of times that the reception is unsuccessful before the first resource selection window (ie, the fault tolerance opportunity), and if it is received more than M3-1 times, it may be received without a high probability. It is considered that the network node is gone or the channel environment is particularly poor, and the reservation of the network node is not considered when the resource is excluded. The value of M3 is pre-configured; for example, different service periods take the same M3 value, or different service periods take different M3 values.

The meaning of N2 is that the first network node that needs to select a resource currently has an estimated upper limit on the number of resource occupation periods to be selected, that is, at least that the selected resource can occupy N2 times periodically and does not occur with the currently excluded resources. conflict. The value of N2 may be related to the requirement of the high-level service packet of the first network node, or may be related to the value of the counter counter selected by the first network node, or may be related to the current channel occupancy status, or may be prioritized with the service. The order is related and is not specifically limited herein.

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

As shown in FIG. 7, UE1 occupies the subframe k (the last transmission subframe), so UE1 cannot receive on the subframe k. Therefore, when selecting the resource, UE1 assumes that there is another subframe k. If the UE occupies any resource in any period (20ms, 50ms, 100ms, 200ms) allowed by the system, UE1 needs to exclude all frequency domain resources on the subframe x in the subframe resource selection window when selecting the resource. If the frame x, the sub-frame x+200, the x+400 and a sub-frame of a sub-frame set coincide, the sub-frame set includes the sub-frame k to select from the resource with a period of 20 ms. The starting position of the window is 5 subframes after the time m+4; it should be noted that if the resource selection window is small, the resources of the five reservations may not completely fall into the resource selection window. The sub-frame set further includes two sub-frames from the start position m+4 of the resource selection window reserved by the sub-frame k in a cycle of 50 ms. It should be noted that if the resource selection window is relatively small, the two times The reserved resources may not fall completely 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 art, and is not specifically limited herein.

In summary, in some embodiments of the present invention, when the network node performs resource selection, for the sending subframe in the listening window, since it cannot monitor the information, any network node can be preset to be allowed by the system. Any frequency domain resource of the sub-frame is occupied by the period, and all frequency domain resources on the sub-frames that overlap with the M4 reservation resources reserved by the sub-frames in a short period of less than 100 ms are excluded. And M4 is equal to 100ms divided by the value of the service period allowed by the system less than 100ms; the method can not only avoid the situation that the network node is disconnected or the channel environment is not good, and the resource elimination is improved. Sex; it is also possible to consider multiple reservations for short periods of less than 100ms, reducing the chance of resource conflicts.

In order to achieve the above objective, as shown in FIG. 8, some embodiments of the present invention further provide a resource exclusion apparatus, which is applied to a first network node, where the apparatus includes: a first acquisition module 51, configured to When the target time triggers the resource selection, the last sending subframe in the first listening window corresponding to the first target moment is obtained; the second determining module 52 is configured to determine the last sending subframe in the first listening window. Whether the resource reserved for each service period of the L allowed by the system satisfies the second preset condition; wherein the second preset condition is that the last transmission subframe is reserved for each service period that is less than L allowed by the system. In the subsequent M3 reservation subframes, any one of the reserved subframes falls within the first resource selection window corresponding to the first target moment; wherein, M3 is a positive integer, L is a positive integer; and the third exclusion module 53 is used When the last one of the transmission subframes is reserved for each service period that is allowed by the system to be less than L, the system is allowed to be less than L according to the last transmission subframe. M4 reservation sub-frames of the service cycle reservation starting from the starting position of the first resource selection window perform resource exclusion; wherein M4 is a positive integer, and M4 is less than or equal to L divided by the service period allowed by the system less than L .

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

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

Specifically, in some embodiments of the present invention, the apparatus further includes: a fourth exclusion module, configured to: when the last transmission subframe is reserved by the system for each service period less than L, the resource does not satisfy the second pre- When the condition is set, resource exclusion is performed according to the last transmission subframe to reserve a reserved subframe for each service period that is less than L allowed by the system.

Specifically, in some embodiments of the present invention, the third exclusion module 53 includes: a second determining submodule, configured to determine a starting position from the first resource selection window according to each service period allowed by the system that is less than L. The last M4 reservation sub-frames of the last transmission sub-frame reservation; the second comparison sub-module is used when the first network node selects resources by the service period P2 and needs to reserve the subsequent N2 times of resources. Comparing 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 exclusion sub-module is configured to determine the exclusion subframe x2 if there is a subframe that overlaps any one of the subframes in the second preset subframe set in the M4 reserved subframes.

In summary, in some embodiments of the present invention, when the network node performs resource selection, for the sending subframe in the listening window, since it cannot monitor the information, any network node can be preset to be allowed by the system. Any frequency domain resource of the subframe is occupied by the period, and all frequency domain resources on the subframe that overlaps with the M4 reservation resources reserved by the subframe in a short period less than L are excluded. And M4 is equal to L divided by the value of the service period allowed by the system less than L; the method can not only avoid the situation that the network node is disconnected or the channel environment is not good, and the resource is not occupied, and the time limit of resource exclusion is improved.

It should be noted that, the resource exclusion device provided by some embodiments of the present invention is a device corresponding to the foregoing resource exclusion method, and all embodiments of the resource exclusion method are applicable to the resource exclusion device, and both can achieve the same or similar The benefits.

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, where the first network node includes at least one selected first resource process 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 subframe, the method includes: Step 71, triggering the resource of the second service process at the second target time When selecting, determining whether the target subframe is the last transmission subframe in the second listening window corresponding to the second target moment; and in step 72, when the target subframe is the last transmitting subframe in the second listening window When the target subframe is reserved for M5 reserved subframes reserved for all service periods 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 transmitting subframe, it is necessary to assume that other network nodes may occupy any frequency domain resources on the transmitting subframe in any system allowed period. All resource domain resources of the sub-frames in the resource selection window must be excluded when performing resource exclusion.

Specifically, in some embodiments of the present invention, in step 72, the method includes: step 721, when the target subframe is reserved by any one of the M6 reservation subframes reserved by the system for the service period less than L, In the second resource selection window, the resource exclusion is performed according to the target subframe to reserve the M5 reservation subframes from the starting position of the second resource selection window reserved by the system for the service cycle less than L; wherein, M6 is A positive integer, and M5 is greater than 1 and less than or equal to L divided by the service period allowed by the system less than L, L being a positive integer.

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

Specifically, L is the maximum delay allowed by the system, and according to the standardization situation of the target, L is equal to 100 ms. For convenience of description, the subsequent description uses 100ms instead of L.

For example, when 100ms is divided by the value of the service period allowed by the system to be less than 100ms, M5 is equal to 100ms divided by the value of the service period allowed by the system less than 100ms; and when 100ms is divided by the service period of less than 100ms allowed by the system When the value is a decimal, M5 is a rounding of the decimal, for example, 100ms divided by the service period of less than 100ms allowed by the system = 3.4, then M5 is equal to 3.

Alternatively, in step 722, when the target subframe is not in the second resource selection window by the subsequent M6 reservation subframes reserved by the system for the service period less than L, the system is allowed according to the target subframe. The M5 preset subframes of the service period reservation less than L perform resource exclusion; wherein M5 is equal to 1.

The following M6 reservation subframes that are reserved by the target subframe in the service period of less than 100ms allowed by the system do not fall into the second resource selection window, specifically: the first time of the last transmission subframe The reserved resource may only fall into the first resource selection window to the end, and the resource is excluded according to the first reserved resource of the last sending subframe; or the M5 reservation resources subsequent to the last sending subframe are dropped. Before entering the starting position of the second resource selection window (for example, all falling into the second listening window), at this time, the resource is excluded according to the M5th reserved resource of the last sending subframe; however, since the reserved resource is in the first Before the resource selection window, the reservation resource substantially does not affect the process of resource exclusion.

Alternatively, in step 723, resource exclusion is performed according to the M5 reserved subframes reserved by the target subframe for the service period allowed by the system to be greater than or equal to L; wherein, M5 is equal to 1.

Further, for a short period of less than 100 ms, the resource is excluded as follows: when the first network node selects a resource for the second service process by using the service period P3 and needs to reserve a subsequent N3 times of resources, step 721 includes: step 7211, Determining M5 reserved subframes of the target subframe reservation after the target subframe according to each service period allowed by the system; and in step 7212, the M5 reserved subframes and the third preset All the sub-frames in the frame set are compared one by one; wherein 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, N3 is an integer greater than or equal to 1; step 7213, if the M5 reservation sub-frame exists and the The sub-frames in which any one of the sub-frames overlaps in the preset sub-frame set are determined to exclude the sub-frame x3.

That is, if the service period allowed by the system includes less than 100 ms, M6 is a pre-configured value. The first network node needs to select resources according to the period P3 and reserve N3 times. When the first network node selects resources, the processing of the sending subframe of the first network node is as follows: Suppose a network node is less than 100 ms. The service cycle occupies any frequency domain resource on the subframe k, and the network node drops any of the M6 reservation resources into the second resource selection window, and then any of the resource selection windows The subframe x3, starting from the beginning of the resource selection window, checks whether the subframe of the M5 reserved resource corresponding to the subframe k is associated with x3, x3+P3, ..., x3+(N3-1)*P3 Any of the sub-frames overlap, and if there is a coincidence, the first network node excludes the sub-frame x3 in its own resource selection window.

It should be noted that the meaning of M6-1 is to control the number of times that the reception is unsuccessful before the first resource selection window (ie, the fault tolerance opportunity), and if it is received more than M6-1 times, it may be received without a high probability. It is considered that the network node is gone or the channel environment is particularly poor, and the reservation of the network node is not considered when the resource is 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 that the first network node that needs to select a resource currently has an estimated upper limit on the number of resource occupation periods to be selected, that is, at least that the selected resource can occupy N3 times periodically and does not occur with the currently excluded resources. conflict. The value of N3 may be related to the requirement of the high-level service packet of the first network node, or may be related to the value of the counter counter selected by the first network node, or may be related to the current channel occupancy status, or may be prioritized with the service. The order is related and is not specifically limited herein.

Further, for a long period greater than or equal to L, the resource is excluded as follows: when the first network node selects a resource for the second service process by using the service period P4 and needs to reserve the next N4 resources, step 723 includes: 7231. Determine, according to the service period allowed by the system that is greater than or equal to L, a reserved subframe for the target subframe reservation; and step 7232, the one reserved subframe and the fourth preset subframe. 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 one reserved sub-frame and the fourth preset sub-frame Any one of the sub-frames in the frame collection coincides to determine the exclusion frame x4.

That is, in the case that the service period allowed by the system includes greater than or equal to 100 ms, the first network node currently needs to select resources according to the period P4 and reserve N4 times. When the first network node selects resources, it is for the first network node. The processing of the transmission subframe is as follows: Suppose a network node occupies any frequency domain resource on the subframe k with a service period greater than or equal to 100 ms, for any message in the resource selection window of the first network node. In block x4, it is checked whether the sub-frame of the next reserved resource corresponding to the sub-frame k coincides with any of the x4, x4+P4, ..., x4+(N4-1)*P4 sub-frames, if there is a coincidence A network node excludes subframe x4 from its own resource selection window.

It should be noted that the meaning of N4 is that the first network node that needs to select a resource currently has an estimated upper limit on the number of resource occupation periods to be selected, that is, at least that the selected resource can occupy N4 times periodically and will not and currently Excluded resources conflict. The value of N4 may be related to the requirement of the high-level service packet of the first network node, or may be related to the value of the counter counter selected by the first network node, or may be related to the current channel occupancy status, or may be prioritized with the service. The order is related and is not specifically limited herein.

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

Specifically, when the first network node selects the resource for the second service process by using the service period P5 and needs to reserve the resource for the subsequent N5 times, the step 73 includes: Step 731, determining the target message according to the service period of the first service process. a sub-frame where the remaining reserved resources after the frame are located, and a target frequency domain resource reserved for each sub-frame; and step 732, the sub-frame and the fifth preset sub-frame set where the remaining reserved resources are respectively located All the sub-frames in the comparison are compared one by one; wherein 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 in which the remaining reserved resource is located exists and the fifth Presetting the sub-frames of any sub-frames in the preset sub-frame set, determining to exclude the target frequency domain resources on the sub-frame x5, or determining to exclude the sub-frame x5.

That is, for any subframe x5 of the second resource selection window, the actual operation of the first service process of the first network node is checked from the start position of the resource selection window of the second service process of the first network node. Whether the reserved resource overlaps with any of the sub-frame x5, the sub-frame x5+P5, ..., the sub-frame x5+(N5-1)*P5, if there is a coincidence, the first network node Exclude the target frequency domain resource on subframe x5 or determine the exclusion subframe x5 in its own resource selection window.

It should be noted that the meaning of N5 is that the first network node that needs to select a resource currently has an estimated upper limit on the number of resource occupation periods to be selected, that is, at least that the selected resource can occupy N5 times periodically and will not and currently Excluded resources conflict. The value of N5 may be related to the requirement of the high-level service packet of the first network node, or may be related to the value of the counter counter selected by the first network node, or may be related to the current channel occupancy status, or may be prioritized with the service. The order is related and is not specifically limited herein.

Further, when the target subframe is the last transmission subframe in the second listening window, the method provided by some embodiments of the present invention further includes: Step 74: determining whether the target subframe is the second listening window. The last transmission opportunity in the next step; in step 75, if the target subframe is not the last transmission opportunity in the second listening window, the resource exclusion is further performed according to the information monitored in the second listening window.

That is, if the target subframe is the last transmission opportunity in the second listening window, the resource exclusion method includes resource exclusion for sending the subframe and resource exclusion for the remaining reserved resources of the first service process; The box is not the last transmission opportunity in the second listening window (that is, after the target subframe, there is one or more transmission opportunities in the second listening window, and the sending opportunity means that it should be sent on the subframe but not sent. In this case, the one or more transmission opportunities can monitor the information of other network nodes to determine the specific occupation of other network nodes.

Specifically, the step 75 includes: Step 751, if the receiving subframe in the second listening window detects that at least one second network node occupies resources in a service period of less than 100 ms, determining whether the second network node satisfies the first a preset condition, wherein the first preset condition is that any one of the M1 secondary reservation resources of the second network node falls within 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 is divided by the value of the service period of the second network node, 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 When the value of the service period of the network node is a decimal, M2 is a rounding of the decimal, for example, 100 ms divided by the service period of the second network node = 3.4, then M2 is equal to 3.

Step 752: When the second network node meets the first preset condition, perform resource exclusion according to the M2 reservation resources that each second network node starts from the starting position of the second resource selection window; wherein, M2 Is a positive integer, and M2 is less than or equal to L divided by the service period of the second network node.

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

Wherein, when the value of the service period of L divided by 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 of the value of L divided by the traffic period of the second network node. When the second network node does not fall into the second resource selection window, the subsequent M1 reservation subframes reserved by the system for the service period less than L, specifically: the first reservation of the last transmission subframe The resource may only fall into the first resource selection window to the end, and the resource is excluded according to the first reserved resource of the last transmission subframe; or the M1 reservation resources subsequent to the last transmission subframe are dropped. Before the starting point of the second resource selection window (for example, all falls into the second listening window), at this time, the resource is excluded according to the M1th reserved resource of the last sending subframe; but since the reserved resource is in the second Before the resource selection window, the reservation resource in essence does not affect the process of resource exclusion.

Further, for a short period of less than L, the resource is excluded as follows: when the first network node selects a resource for the second service process with the service period P6 and needs to reserve the next N6 times, step 752 includes: step 7521, Determining, according to the service period of the second network node, the subframe where the M2 reservation resources are located after the target subframe, and the second frequency domain resource reserved on each subframe; and step 7522, the M2 times The subframe where the reserved resource is located is compared with all the subframes in the sixth preset subframe set; wherein the sixth preset subframe collection is {subframe x6, subframe 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 subframe corresponding to any one of the subframes in the sixth preset subframe set in the subframe where the M2 reservation resource is located, it is determined to exclude the second frequency domain resource on the subframe x6.

That is, in the case that the service period allowed by the system includes less than 100 ms, for the second network node whose service period is less than 100 ms, M1 is a pre-configured value. The first network node needs to select resources according to the period P6 and reserve N6 times. When the first network node selects a resource, the processing of the receiving subframe of the first network node is as follows: receiving the first network in the subframe The road node can listen to information of other network nodes (generally, the scheduling signaling SA) to learn information about other network nodes' service periods, resources, and reserved resources. If the first network node detects, in the first listening window, that the second network node occupies the frequency domain resource D (ie, the first frequency domain resource) on the subframe K with a service period of less than 100 ms, and the second network If any one of the reserved resources of the M1 reservations of the path node falls within the first resource selection window, then any subframe x6 in the first resource selection window is counted from the beginning of the first resource selection window. Check whether the sub-frame of the M2 reservation frequency domain resource D corresponding to the sub-frame k is associated with any of the sub-frame x6, the sub-frame x6+P6, ..., the sub-frame x6+(N6-1)*P6. The sub-frames coincide, and if there is a coincidence, the first network node excludes the frequency domain resource D on the subframe x6 in its own first resource selection window.

It should be noted that the meaning of M1-1 is to control the number of times that the reception is unsuccessful before the first resource selection window (ie, the fault tolerance opportunity), and if it is received more than M1-1 times, it may be received without a high probability. It is considered that the network node is gone or the channel environment is particularly poor, and the reservation of the network node is not considered when the resource is excluded. The value of M1 is pre-configured; for example, different service periods take the same M1 value, or different service periods take different M3 values.

The meaning of N6 is that the first network node that needs to select a resource currently has an estimated upper limit on the number of resource occupation periods to be selected, that is, at least that the selected resource can occupy N6 times periodically and does not occur with the currently excluded resources. conflict. The value of N6 may be related to the requirement of the high-level service packet of the first network node, or may be related to the value of the counter counter selected by the first network node, or may be related to the current channel occupancy status, or may be prioritized with the service. The order is related and is not specifically limited herein.

Further, for a long period greater than or equal to L, the resource is excluded as follows: Step 75 further includes: Step 753: If at least one third network node is monitored on the receiving subframe in the second listening window is greater than or A service period equal to L occupies resources, and resource exclusion is performed according to a subsequent reserved resource of each third network node.

And when the first network node selects the resource for the second service process by using the service period P7 and needs to reserve the resource for the subsequent N7 times, the step 753 includes: Step 7531, determining the third network according to the service period of the third network node. a sub-frame where the reservation resource is located next to the path node, and a third frequency domain resource reserved on the sub-frame; and step 7532, the sub-frame and the seventh preset sub-frame set where the reserved resource is located All the sub-frames in the comparison are compared one by one; wherein 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 reserved resource is located and the seventh preset Any one of the sub-frames in the subframe set coincides to determine the third frequency domain resource on the subframe x7.

That is, in the case that the service period allowed by the system includes greater than or equal to 100 ms, the first network node currently needs to select resources according to the period P7 and reserve N7 times. When the first network node selects resources, it is for the first network node. The processing of the receiving subframe is as follows: The first network node in the receiving subframe can listen to information of other network nodes (generally, the scheduling signaling SA) to learn the service period, resources, and reserved resources of other network nodes. And other information. If the first network node detects in the first listening window that the third network node occupies the frequency domain resource D (ie, the third frequency domain resource) on the subframe K with a service period greater than or equal to 100 ms, A sub-frame x1 in a resource selection window checks whether the sub-frame of the frequency domain resource D in the subsequent sub-frame k is sub-frame x7, sub-frame x7+P7, ..., sub-frame x7+ Any subframes in (N7-1)*P7 are coincident. If there is a coincidence, the first network node excludes the frequency domain resource D on the subframe x7 in its own first resource selection window.

It should be noted that the meaning of N7 is that the first network node that needs to select a resource currently has an estimated upper limit on the number of resource occupation periods to be selected, that is, at least that the selected resource can occupy N7 times periodically and will not and currently Excluded resources conflict. The value of N7 may be related to the requirement of the high-level service packet of the first network node, or may be related to the value of the counter counter selected by the first network node, or may be related to the current channel occupancy status, or may be prioritized with the service. The order is related and is not specifically limited herein.

For example, the service period allowed by the system is 20ms, 50ms, 100ms, 200ms, assuming M(20ms)=3, M(50ms)=2. UE1 selects a resource in the resource selection window of the second service process at time m, and occupies the resource three times with a period of 200 ms.

As shown in FIG. 10, it is assumed that the first network node has two service processes, and now the second service process selects resources. Assume that the first service process occupies the subframe k (the subframe k is the last transmission subframe), but hangs in the subframe k+20 (the subframe k+20 is the last transmission opportunity) (ie, the first service process should be sent on the subframe k+20 but not actually), the first network node can receive on the subframe k+20, and find that other network nodes are in the subframe k+ If the frequency domain resource is occupied by the period of 50 ms, the second service process of the first network node needs to exclude the reserved frequency domain resource on the subframe x in the subframe resource selection window when selecting the resource, if the child If the frame x, the sub-frame x+200, and the x+400 coincide with a sub-frame in a sub-frame set, the reserved resources on the sub-frame x are excluded.

The subframe set includes eight subframes that are reserved by the subframe k in a period of 20 ms, and 8 is an actual remaining number of reserved resources of the first service process of the first network node; the subframe collection is further The sub-frame k includes two sub-frames reserved in a cycle of 50 ms. It should be noted that if the resource selection window is relatively small, the resources of the two reservations may not completely fall into the resource selection window.

In summary, in the resource exclusion method provided by some embodiments of the present invention, the first network node includes multiple service processes, and when the second service process that does not select the resource selects resources, the first service process of other selected resources needs to be considered. The reserved resource (specifically, the remaining first service process starting from the starting position of the resource selection window of the second service process is the actual reserved resource), thereby avoiding collision with resources of the first service process and avoiding disconnection of the network node If the open or channel environment is not good, the subsequent non-resources will improve the timeliness of resource exclusion.

In order to achieve the above objective, as shown in FIG. 11, some embodiments of the present invention further provide a resource exclusion apparatus, which is applied to a first network node, where the first network node includes at least one selected resource.

The box performs resource exclusion; wherein M6 is a positive integer, and M5 is greater than 1 and less than or equal to L divided by the service period allowed by the system to be less than L; and/or the fourth exclusion sub-module is used as the target subframe. If the subsequent M6 reserved sub-frames reserved by the system for the service period less than L are not in the second resource selection window, the M5 pre-reserved according to the target sub-frame is allowed by the system to allow the service period less than L. The sub-frame is configured to perform resource exclusion; wherein, M5 is equal to 1; and/or, the fifth exclusion sub-module is configured to reserve M5 subscription sub-messages according to the target sub-frame with a service period allowed by the system greater than or equal to L.
