Description

A kind of resource control method and network node

Technical field

The present invention relates to field of communication technology, particularly relates to a kind of resource control method and network node.

Background technology

3GPP RAN1 meetings at present determine that V2V safety services use the open loop SPS machines based on (sensing) mechanism of monitoring System.86 meetings of 3GPP RAN1 determine the trigger condition of resource collision, trigger the combination of two conditions of resource gravity treatment at present For：The internal maintenance resource timer (counter) and system configuration probability (P) of open loop resource.

Open loop counter triggerings resource gravity treatment mechanism generally refers to：Node is sensing always, but at the same time, once choosing The resource is selected, in the case of no other conditions (such as bag size, packet delay) are ungratified, are exactly pure open loop SPS mechanism, that is, work as When selecting certain resource for the first time, a value is randomly choosed between [5,15] as the corresponding open loop SPS's of the resource Counter, a TB (Transport Block, transmission block), is sent completely the counter and subtracts 1 on the resource, when When the counter is kept to 0, node discharges the resource, i.e. the resource is no longer semi-continuous (SPS) money for node maintenance Source.

System configuration probability (P) triggering resource gravity treatment mechanism generally refers to：System, which is pre-configured with, changes resource probability P, section Point one random number of selection in [0,1], if this random number is more than system configuration probability (P), changes resource；If this Random number is less than or equal to system configuration probability, then does not change resource.

Above-mentioned two condition is combined the method used：When counter is kept to 0, maintenance is not released immediately SPS resources, but random number is produced, compared according to system configuration probability (P), it is determined whether resource is changed, if money need not be changed Source, then be continuing with the SPS resources safeguarded before；Resource is changed if desired, then discharges the SPS resources safeguarded before.

In addition, node needs to indicate whether reservation resource next time in SA when dispatch (SA) is sent, when Reservation next time resource when, the cycle (information i.e. on time dimension, on frequency domain of reserve resource next time is carried in SA Information be consistent), the value in the cycle is P × i, and P is system fixed configurations, is 100ms, and i represents cycle parameter, and value is Between [1,10].I.e. each resource block (TB) reserve resource is the resource for preengaging next TB, does not preengage follow-up excessively Resource.The position of specific resource is e=d+100*i, and the position instruction of d is data that current scheduling signaling SA is associated here The position of information data, can be known by SA other guides.The time-domain position of reserve resource can know that frequency domain part is not Become, and then the running time-frequency resource preengage.I=0 characterizations are not preengage next time, and 1<=i<=10 contain give out a contract for a project at intervals of The TB resources of 100ms~1s.

Vehicle-to-vehicle V2V message is mainly collaborative perception category information CAM and decentralized environment notification information DENM.DENM message There is regular hour limitation in cycle itself, i.e., is not that vehicle launch just continues up afterwards, it is possible to occur counter>0 but service ending scene.

For CAM message, its transmission frequency depend on：1) determined by vehicle oneself state：Position, speed etc.；2) some CAM can be adjusted using application and sends interval, can be arbitrary value, be considered as not having strict periodicity, but can To regard as with certain relative cycle (vehicle-state is a process that can be speculated, become slowly), but length of periodicity is not true It is fixed.It is likely to occur counter>0 but the service ending (send opportunity reach in when without high-level business bag) in the cycle.

The trigger condition of resource gravity treatment of the prior art：SPS counter time-out, it is probability to need to carry out resource weight Choosing；If the resource of currently used maximum allowable modulation and coding strategy MCS distribution, can not meet the transmission of TB, it is necessary to Carry out resource gravity treatment；When Current resource cannot meet the delay requirement of the TB, it is necessary to carry out resource gravity treatment.As long as Radio Resource control RRC configurations resource pool processed changes, the relevant terminal UE of resource in the resource pool that media access control layer (MAC layer) triggering changes Initiate resource gravity treatment.

Resource selection and the flow of gravity treatment：(1) according to the corresponding decodings of SA being successfully decoded in sensing information and Metrical information carries out resource exclusion to the resource in selection window；(2) according to sensing information acting counting smooth, candidate is determined Resource collection；(3) suitable resource is selected in definite candidate resource set.

Specifically, (1) resource exclusion process：

Two kinds of situations, the first situation:Indicated according to dispatch SA, from the angle of resource occupation, judge to exist follow-up First resource block TB takes the possibility that resource collides：The node of transmission SA is subscribed to the resource in selection window, then such as Shown in Fig. 1 interior joints A.The second situation：Indicated according to dispatch SA, from the angle of resource occupation, judge to exist it is follow-up its His resource block TB takes the possibility that resource collides：Although the node of transmission SA does not preengage the resource in selection window, That is the resource of the node reservation of transmission SA is outside selection window, if but selection resource node selects certain in selection window If resource, there is the possibility collided with the node of transmission SA in following following resource block TB, as shown in Fig. 1 interior joints C.

Determine the ratio of optional resource in resource selection window, when the ratio of current optional resource is more than or equal to 20%, Resource exclusion process terminates；When optional resource than row be less than 20% when, improve current transmitting-receiving node power threshold (3dB, it is each Initial value is system configuration during secondary resource selection, and subsequently iteration updates always), reduce resource multiplex scope and re-start resource Deduct.

(2) power smooth process：

As shown in Fig. 2, the surplus resources not excluded for resource in selection window, power is average, is ranked up, screening Wherein 20% relatively low resource of smooth power.

1) surplus resources are selected：In selection window step 2 deduct resource after remaining all resources, no matter the resource pair Whether there is the SA being successfully decoded accordingly in the sensing windows answered.2) it is averaged to surplus resources power：The grain of power averaging Spend for 100ms, (most 10 resources, excluding node can not do the resource in a length of sensing windows of window of power averaging The resource of sensing), here for for linear averaging.3) processing of the S-RSSI metrical informations of corresponding resource：The granularity of measurement is all It is subchannel, does not do any specially treated, the linear averaging of general power is measured on each sub-channels.

(3) resource selection process

First re-transmission resource selection process when the number of transmissions is 2：2 moneys are randomly choosed in 20% resource minimum from power Source, the interval for ensureing the two resources is in [- 15,15] subframe and interval cannot be 0；When the number of transmissions is 1, it is only necessary to from time Select one resource of random selection in resource.

In the prior art, counter is worked as>0 and without high-level business in the case of there are two kinds for the treatment of mechanisms (not have meeting also at present Discuss conclusion)：Method 1：Continue to safeguard the resource, hang up counter, when new business packet reaches, if size can be with Carrying, time delay can continue to use the resource with meet demand；Method 2：Release immediately the resource.

In method 1, when for other nodes, this resource is not subscribed to, so then it is possible to this A part of resource is placed on inside candidate resource, when node itself uses, it is possible to collide.

The content of the invention

It is an object of the invention to provide a kind of resource control method and network node, solve in the prior art when In the case that counter is more than 0 and is reached without high-level business, when node itself is using the resource being suspended, existing resource is touched The problem of hitting.

Embodiment

To make the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool Body embodiment is described in detail.

First embodiment

As shown in figure 3, the first embodiment of the present invention provides a kind of resource control method, applied to a network node, bag Include：

Step 301, the value of the internal maintenance Resource Counter counter for the first resource currently safeguarded when network node is big In zero and the first resource arrival moment sent without high-level business bag when, hang up the first resource；

Step 302, the network node is in the subframe where reception subframe, the first resource hung up and based on net Monitored in the subframe for the follow-up send opportunity corresponding with the first resource that the semi-static scheduling cycle of network node determines Operation；

Step 303, when object time has new high-level business bag to reach and judges in the corresponding selection window of object time The resource of first resource reservation be when can carry new high-level business bag, according to being listened in the corresponding audit window of object time Information carry out resource exclude judge；

Step 304, if the resource that first resource is preengage in the corresponding selection window of object time is excluded, hang-up is discharged The value of the internal maintenance Resource Counter counter of the first resource and the first resource, and trigger resource gravity treatment；

Step 305, if the resource that first resource is preengage in the corresponding selection window of object time is not excluded, in target Carve and send new high-level business bag in the resource that first resource is preengage in corresponding selection window.

In the first embodiment of the present invention, when the internal maintenance Resource Counter for the first resource that network node is currently safeguarded When the value of counter is more than 0 and is sent without high-level business bag, continue to safeguard the first resource, that is, hang up first resource.Need It is bright, operation counter can be to continue with, counter can also be hung up, be not especially limited herein.And network node one Straight do monitors sensing operations, i.e., the scheduling of other network nodes is monitored in monitoring subframe of the network node in audit window Signaling OA, measurement power and reception data；Specifically, since audit window is the dynamic window dynamic with the time, therefore this hair The corresponding audit window of object time that signified audit window reaches for new high-level business in bright embodiment.Wherein, hang up First resource where subframe can be used as and monitor subframe, such as when the subframe where the first resource of hang-up is in current When in audit window, then the subframe where the first resource hung up is as subframe is monitored, i.e., network node is where first resource Subframe on carry out snoop-operations.Further, what the semi-static scheduling cycle based on network node determined provides with described first The subframe of other corresponding send opportunity of source can be used as monitoring subframe, for example, the subframe where the first resource hung up does not have Have in current audit window, but with the propulsion of time, the subframe of the corresponding follow-up send opportunity of the first resource It is possible to fall into the audit window slided in real time, then when follow-up subframe is fallen into audit window, then will falls into monitoring window Subframe in mouthful carries out snoop-operations as subframe, i.e. network node is monitored on the subframe in audit window is fallen into.

Further, when the selection that resource need not be triggered when transmission transmission block TB on the first resource and again Choosing, i.e., when no high-level business bag send, either high-level business bag reach and determine triggering resource gravity treatment when or high-level business bag When reaching but judge to use the resource of other hang-up, this current first resource hung up, which continues to hang up, to be safeguarded, no Process.

And when the new high-level business bag of judgement reaches and can continue to the object time reached using new high-level business bag When the resource that first resource is preengage in corresponding selection window, increase the process that a resource excludes and judge the selection window Whether interior corresponding resource can be continuing with.If corresponding with first resource in the corresponding selection window of object time arranged Remove, then show that the resource cannot be continuing with, then discharge the first resource of hang-up and control network node to carry out resource weight Choosing；If the resource that first resource is preengage in the corresponding selection window of object time is not excluded, show that the resource can be after Continuous to use, then the corresponding resource being continuing with the selection window, first resource is pre- in the corresponding selection window of object time New high-level business bag is sent in resource about.

Specifically, in the first embodiment of the present invention, step 303 includes：

Step 3031, when object time has new high-level business bag to reach, determine the new high-level business bag that reaches with Whether the first resource of hang-up belongs to same process；Wherein, it is mainly preferential according to often bag to judge whether it belongs to same process ((LCID) is judged by level (ProSe Per-Packet Priority, PPPP) or logic channel ID.

Step 3032, if new high-level business bag is not belonging to same process with the first resource hung up, the target is determined The resource that first resource is preengage in moment corresponding selection window can not carry the new high-level business bag and not to described First resource processes；

Step 3033, if new high-level business bag belongs to same process with the first resource hung up, according to new height The business packet size and service delay demand of layer service bag judge first resource reservation in the corresponding selection window of object time Whether resource can carry new high-level business bag；

Step 3034, when the business packet size of new high-level business bag meets the first preset condition, and service delay demand Meet the second preset condition, determine that the resource that first resource is preengage in the corresponding selection window of the object time can carry institute New high-level business bag is stated, and resource is carried out according to the information listened in the corresponding audit window of object time and excludes to judge；

Step 3045, when the business packet size of new high-level business bag is unsatisfactory for the first preset condition, or service delay Demand is unsatisfactory for the second preset condition, determines that the resource that first resource is preengage in the corresponding selection window of the object time cannot The new high-level business bag is enough carried, discharges the first resource of hang-up and the internal maintenance resource of the first resource The value of counter counter, and trigger resource gravity treatment.

Wherein, the first preset condition refers specifically to the resource distributed on first resource using maximum allowable MCS, disclosure satisfy that The transmission demand of the business packet size of new high-level business bag, then meet the first preset condition, conversely, it is default to be then unsatisfactory for first Condition；Second preset condition refers specifically to the service delay demand that first resource disclosure satisfy that new high-level business bag, then meets Two preset conditions, conversely, being then unsatisfactory for the second preset condition.

Firstly the need of the first resource for determining the new high-level business bag reached with hanging up in the first embodiment of the present invention Whether belong to same process, if new high-level business bag is not belonging to same process with the first resource hung up, determine the target In moment corresponding selection window first resource preengage resource can not carry the new high-level business bag and need not pair First resource carries out any processing；If new high-level business bag belongs to same process with the first resource hung up, need into one Step judges whether new high-level business bag can be sent out in the resource that first resource is preengage in the corresponding selection window of object time Send.Specifically, can new high-level business bag be sent out in the resource that first resource is preengage in the corresponding selection window of object time Send what is mainly determined according to the business packet size of new high-level business bag and service delay demand etc., if the object time pair The resource that first resource is preengage in the selection window answered can carry the new high-level business bag, it is determined that new high-level business Bag can be sent in the resource that first resource is preengage in the corresponding selection window of the object time, and further according to The information listened in the audit window of network node carries out resource and excludes to judge；And work as the corresponding selection window of the object time When the resource of first resource reservation can not carry the new high-level business bag in mouthful, then show that new high-level business bag cannot Sent in enough resources that first resource is preengage in the corresponding selection window of the object time, need the first of release hang-up at this time Resource simultaneously controls network node to carry out resource gravity treatment at the same time, and the new high-level business bag for arrival selects new resource and associates new Counter values.

Further, step 303 in the first embodiment of the present invention, including：

Step 3036, resource that first resource in the corresponding selection window of object time preengages is determined and based on network section The corresponding resource of follow-up send opportunity corresponding with the first resource that the semi-static scheduling cycle of point determines is detection resource；

Step 3037, the information listened in the corresponding audit window of the object time is decoded, determines institute State the sending next time of the dispatch instruction that is successfully decoded in audit window or under the reserve resource that sends several times；

Step 3038, judge whether the reserve resource collides with the detection resource；

Step 3039, if the reserve resource does not collide with the detection resource, the corresponding choosing of object time is determined The resource that first resource is preengage in window is selected not to be excluded；If the reserve resource collides with the detection resource, determine The resource that first resource is preengage in the corresponding selection window of object time is excluded.

As shown in figure 4, the first embodiment of the present invention determines detection resource first, detection resource includes two parts resource, A part of resource is：Resource of the first resource correspondence of hang-up in selection window is (i.e. in the corresponding selection window of object time The resource of first resource reservation)；Another part resource is：First money of the hang-up that the fixed cycle according to first resource determines (what i.e. the semi-static scheduling cycle based on network node determined is corresponding with the first resource for the resource of the follow-up send opportunity in source The corresponding resource of follow-up send opportunity).Secondly, reserve resource is determined, reserve resource is：According to monitoring in audit window The reserve resource for other nodes that the information listened on frame decodes.Finally, judge reserve resource whether with monitoring resource Collision is sent, i.e., whether the follow-up first resource of other nodes reservation collides with monitoring resource in audit window.It is if described Reserve resource does not collide with the detection resource, determines the money that first resource is preengage in the corresponding selection window of object time Source is not excluded；If the reserve resource collides with the detection resource, determine in the corresponding selection window of object time The resource of first resource reservation is excluded.

Further, judge whether the reserve resource is sent out with the detection resource described in the first embodiment of the present invention After raw collision, the method further includes：

Step 306, if reserve resource collides with the detection resource, determine in the corresponding selection window of object time The resource of first resource reservation is excluded；

Step 307, if reserve resource does not collide with the detection resource, determine the detection resource in object time The resource of the counting smooth that needs to do work in corresponding audit window, and the resource to being used for power smooth in audit window is done linearly Power smooth, obtains smooth power；If the smooth power is less than predetermined threshold value, the corresponding selection window of object time is determined The resource of interior first resource reservation is not excluded；If the smooth power is more than or equal to predetermined threshold value, when determining target The resource that first resource is preengage in corresponding selection window is carved to be excluded.

Further, can be further if do not collided by the first resource that the above process determines to hang up Judged by the way that the energy smoothing process of the first resource of hang-up is further, and a general power thresholding is set, if smoothly Power afterwards exceedes thresholding, then it is assumed that needs the gravity treatment that starts out at once；If it is not above thresholding, then it is assumed that can be continuing with providing Source.Item Smoothing at intervals of 100ms, the window of Item Smoothing can be all resources in audit window, can also be into one Step be reduced into resource hang up the moment after terminate to audit window before resource.

As shown in figure 5, the first embodiment of the present invention is used for work(firstly the need of definite detection resource in audit window The resource of counting smooth, the process is compared with process, granularity 100ms；Secondly to the resource in audit window for power smooth It is smooth to do linear power, obtains smooth power；Further judgement is finally done to smooth power, one power threshold of increase is sentenced It is fixed.If the power after smooth exceedes predetermined threshold value, then it is assumed that first resource is excluded, then needs the resource weight that starts out at once Choosing；If the power after smooth is not less than predetermined threshold value, then it is assumed that first resource is not excluded, then be continuing with the resource into Row business packet is sent.
