Detailed description of the invention
In order to solve off-grid node and the reliable communication problem between net node, embodiments provide
A kind of resource allocation methods and equipment.
Below in conjunction with Figure of description, the preferred embodiments of the present invention are illustrated, it will be appreciated that this place
The preferred embodiment describing is merely to illustrate and explains the present invention, is not intended to limit the present invention.And not
In the case of conflict, the embodiment in the application and the feature in embodiment can be mutually combined.
Below in conjunction with the accompanying drawings, the method and apparatus providing the present invention with specific embodiment is described in detail.
In the following description, first Resource Allocation Formula is described with base station for executive agent, afterwards with at net
Node is that Resource Allocation Formula is described by executive agent, finally with off-grid node for executive agent to resource
Allocative decision is described.
See Fig. 5, be that the flow process of the resource allocation methods with base station as executive agent of the embodiment of the present invention is shown
It is intended to, comprise the following steps:
Step 501: base station determination is in needing and its week at net node of the fringe region of own coverage area
Enclose off-grid node and carry out resource coordination, afterwards step 502;
In this step 501, base station can according to the information that there is off-grid node at net node around reporting,
Determine in the fringe region being in own coverage area net node need with around off-grid node carry out
Resource coordination;
Preferably, base station determine in the following manner be in own coverage area fringe region at net node
Need to carry out resource coordination with off-grid node about:
Base station judges that the last time receives the time that there is off-grid nodal information around net node reports
Whether the duration of distance current time is more than the 3rd setting duration;If judged result is for the no more than the 3rd setting
Long, it is determined that be in own coverage area fringe region need to enter with off-grid node about at net node
Row resource coordination;If judged result is for more than the 3rd setting duration, it is determined that be in the limit of own coverage area
Edge region do not need to carry out resource coordination with off-grid node about at net node;
When not needing to carry out resource coordination, also just without carrying out below step 502 to step 506, continue
Continue and be received there is off-grid nodal information around net node reports, proceed above-mentioned judgement operation;
If not receiving, in view of base station, the week reporting at net node in a long time during the embodiment of the present invention here
Enclose and there is off-grid nodal information, then it is believed that the off-grid that do not exists around net node in self coverage saves
Point, now, also avoids the need for carrying out the resource coordination at net node and off-grid node, and base station is in distribution subframe
When resource, as long as the sub-frame resources taking at net node in avoiding own coverage area does not collides
And coordinate and the taking of the substation resource under other base station coverage area, it is not necessary to consider and off-grid
The cooperation of the resource that node uses.
Step 502: base station receives the sub-frame resources demand information reporting at net node, step 503 afterwards;
In this step 502, the sub-frame resources demand information that base station reception reports at net node includes:
Receive and report during net node carries out network insertion by transferring to for off-grid node before at net node
The sub-frame resources information currently taking;
Or
Receive at net node in the marginal zone being entered base station range by the central area of base station range
The resource allocation request information reporting during territory.
Wherein, above-mentioned reception carries out network insertion at net node at net node by transferring to for off-grid node before
The sub-frame resources information currently taking reporting in journey can be divided into two kinds of situations, and the first situation is: receives
It at net node by transferring at net node for off-grid node before, is continuing with original time interval resource, carry out network
The sub-frame resources information currently taking reporting in access procedure;The second situation is: receive net node by
Transfer at net node for off-grid node before, discharge original time interval resource, report during carrying out network insertion
The sub-frame resources information currently taking;
At net node or at net node, base station is being covered model at net node by transferring to for off-grid node before
When the central area enclosed enters the fringe region of base station range, owing to these are sent out in net node present position
Give birth to change so that the sub-frame resources currently taking is from will not collide can become with off-grid node before
The sub-frame resources that the sub-frame resources that may use with off-grid node collides, accordingly, it would be desirable to carry out current son
Frame resource report or ask to carry out the distribution of resource, showing its demand sub-frame resources, and then make base
Stand and distribute, for it, the sub-frame resources that will not collide, it is ensured that the communication between net node and off-grid node
Reliability.
Step 503: base station judges that report sub-frame resources demand information is positioned at own coverage area at net node
Fringe region in;If the determination result is YES, then step 504;If judged result is no, then perform
Step 505;
In this step 503, geographical location information that base station can report at net node according to each, should be
The equipment to this node for the net node measures, to network D2N link channel, the measurement obtaining and ties and to this joint
One or more in the timing advance TA that point sends judge whether this is positioned at self at net node and covers
In the fringe region in region.Here the fringe region of base station coverage area and the regional extent of central area are permissible
Pre-set.
Step 504: base station from whole sub-frame resources except it may happen that collision sub-frame resources in addition to and not by
Distribute to other in the sub-frame resources of net node, select at least one sub-frame resources;Step 506 afterwards;
Wherein, it is described it may happen that the sub-frame resources of collision is simultaneously by off-grid node and own coverage area
Net node use sub-frame resources;
Step 505: base station according to existing resource allocation methods be report sub-frame resources demand information at net
Node distributes sub-frame resources;
Step 506: at least one sub-frame resources selecting is handed down to report sub-frame resources demand information by base station
At net node.
It is also preferred that the left it is described it may happen that the sub-frame resources of collision is the sub-frame resources in off-grid cooperation resource pool;
Wherein, used by off-grid node off-grid cooperation resource pool in sub-frame resources and net cooperation resource pool
In sub-frame resources be the parts of whole sub-frame resources that base station can be distributed, and off-grid cooperation resource pool
Orthogonal with the sub-frame resources in net cooperation resource pool.
Based on the sub-frame resources cooperating off-grid in resource pool as it may happen that the son of sub-frame resources of collision
Frame Resource Allocation Formula can be understood as, under scheduling mode in base station set, dividing based on geographical position planning
Supplementing of sub-frame resources allocative decision during sub-frame resources, owing to dividing sub-frame resources based on geographical position planning
When, the sub-frame resources that base station can be distributed determines that, therefore, it can be divided into sub-frame resources three parts,
Part I is off-grid cooperation resource pool, and Part II is at net cooperation resource pool, and Part III is base station energy
Sub-frame resources in addition to Part I and Part II in the sub-frame resources of enough distribution, Part I subframe provides
Source can be used to specialize in off-grid node and uses, and Part II sub-frame resources can be used to specialize in and is positioned at self covering
Using at net node of fringe region in region, Part III can be used to specialize in and is positioned at own coverage area
Central area net node use.Change (from base station coverage area in the position at net node
Central area moves to fringe region, moves to central area from the fringe region of base station coverage area, or
Become at net node from the fringe region for off-grid node entrance base station coverage area before) when, at net node
Report resource allocation request or report the sub-frame resources currently taking, base station accordingly based upon its position come for
It redistributes sub-frame resources;Off-grid node by the fringe region being in base station coverage area before at net
When node is changed into off-grid node, it is off-grid cooperation money that off-grid node self can adjust the sub-frame resources of self
Sub-frame resources in pond, source, guarantees off-grid node and the sub-frame resources using at net node would not be sent out
Raw collision.
Below by an example to the sub-frame resources cooperating off-grid in resource pool as it may happen that collide
The sub-frame resources allocative decision of sub-frame resources illustrate:
Assume that node A is that node B is off-grid node, and whole resource is 100, subframe at net node
Sub-frame resources in 0~10 composition off-grid cooperation resource pool, subframe 11~20 composition is in net cooperation resource pool
Sub-frame resources.Base station, based on geographical position zoning, for the fringe region in base station coverage area, is
This base station coverage area inward flange region configured, at net node, the subframe that off-grid nodal test reports in advance
Resource.When node A enters into the fringe region in base station coverage area, and determine week by preamble detection
Enclosing when there is off-grid node, reporting base station by around there is off-grid nodal information.Base station receives around deposits
After off-grid nodal information, the edge that is adjusted in base station coverage area of sub-frame resources that node A is used
The sub-frame resources in the distribution of net node in region, i.e. fringe region in this base station coverage area only can be used in
Sub-frame resources in net cooperation resource pool.Enter into overseas edge, base station overlay area as off-grid node B
Region, and determine around exist when net node by preamble detection, adjust and self use off-grid cooperation money
Sub-frame resources in pond, source.When node A is with movement, when entering into without network's coverage area, abandon using
Original resource, the preferential resource using in off-grid cooperation resource pool.Further, node A continues to move to,
There is subframe collision, needing to reselect sub-frame resources, if can't detect depositing at net node this when
The selection of idle subframe can carried out in all sub-frame resources.
It is alternatively above-mentioned it may happen that the sub-frame resources of collision is constituted off-grid in static or semi-static mode
Cooperation resource pool, base station also avoid the need for (in real time) determine it may happen that collide sub-frame resources;Additionally,
Base station also can being determined by any one in following two mode or whole mode in real time it may happen that
The sub-frame resources of collision:
Mode one, it comprises the following steps a1 to step a3:
Step a1: base station receives the interference carrying the sub-frame resources information that interference occurs reporting at net node
Instruction information;
Around net node can listen to net node and/or around the interference of sub-frame resources of off-grid node,
And the interference instruction information reporting of the sub-frame resources information that interference occurs will be carried to base station;
Step a2: base station determines the sub-frame resources that interference occurs by accounting at net node in own coverage area
With, and the sub-frame resources that the sub-frame resources of this generation interference is multiplexed by off-grid node simultaneously;
Owing to sub-frame resources is base station distribution, therefore, base station may determine that a certain sub-frame resources specifically by which
Individual take at net node, therefore, occurring the resource of interference by own coverage area at net joint
When point takies, base station may determine that the sub-frame resources that this generation is disturbed is multiplexed by off-grid node simultaneously.
Step a3: base station is defined as the sub-frame resources that this generation is disturbed it may happen that the sub-frame resources collided;
Mode two, it comprises the following steps b1 to step b3:
Step b1: potential off-grid at net node in prediction own coverage area, base station;
Step b2: base station determine in own coverage area off-grid at net node;
The execution sequence of above-mentioned steps b1 and step b2 in no particular order, can first carry out b1, then perform
b2;Also step b2, then step b1 can be first carried out;Can hold parallel with step b1 and step b2
OK.
Step b3: base station by predict potential off-grid net node use sub-frame resources and be confirmed as
The sub-frame resources using at net node of off-grid is defined as it may happen that the sub-frame resources collided.
Due to may being determined still in the fringe region of own coverage area at net node of potential off-grid
For off-grid net node its distance base station coverage edge certain distance when still to current subframe
Resource is assigned impact, if by potential off-grid net node and be confirmed as off-grid net node use
Sub-frame resources distribute in own coverage area at net node, it will make this sub-frame resources largely
Upper can the spacing of simultaneously quilt be not reaching to sub-frame resources multiplex distance at net node and off-grid node or
Using with at net node at net node, this use allowing for sub-frame resources collides, and then makes simultaneously
Described net node and off-grid node cannot be carried out communication, also cannot enter at net node and off-grid node with other
Row communication, accordingly, it would be desirable to by prediction potential off-grid net node use sub-frame resources and be determined
The sub-frame resources using at net node for off-grid is defined as it may happen that the sub-frame resources collide, it is to avoid distribute
Give at net node, also just largely on decrease the possibility that sub-frame resources collides.
Concrete, base station can predict own coverage area in the following manner in potential off-grid at net joint
Point:
According to the timing advance TA sending at net node to this, should believe in the geographical position that net node reports
Cease and to network D2N link channel, the measurement result three obtaining is measured at the equipment of net node to this
In one or more, it was predicted that should net node be potential off-grid at net node.
Can be analyzed to the TA sending at net node according to each time, if the general trend of TA is to increase
, illustrate that this is more and more remote in net nodal distance base station, and then predict this net node be potential off-grid
Net node;The motion track of node can be drawn according to the geographical location information repeatedly reporting at net node,
This track for during away from the coverage of base station, measurable should net node be potential off-grid at net node;
Same, take multiple measurements the multiple measurement results such as signal strength signal intensity obtaining to D2N link channel and enter
Row is analyzed, if the general trend of signal strength signal intensity dies down, then measurable should be potential off-grid at net node
At net node;
Further, can determine in the following manner in own coverage area off-grid at net node:
For each be predicted to be potential off-grid at net node, it is judged that first setting duration in whether receive
It is predicted to be the information sending at net node of potential off-grid to this;
If not receiving, it is determined that this be predicted to be potential off-grid in net node is own coverage area
Off-grid at net node;If receiving, it is determined that this be predicted to be potential off-grid net node still in from
In body overlay area;
Due to off-grid when the off-grid duration of net node is longer, due in vehicle net at net node and off-grid
The mobility of node is relatively strong, off-grid net node often away from base station coverage distance relatively
Far (more than the multiplex distance of sub-frame resources), even if using the sub-frame resources that this off-grid node uses, also not
Interfere between the sub-frame resources that meeting and this off-grid node use, accordingly, it would be desirable to the subframe money being taken
Source is from it may happen that remove the sub-frame resources of collision, in order to the sub-frame resources that base station can be taken is distributed to
At net node, namely it is also preferred that the left described method also includes:
The off-grid duration at net node of off-grid described in judgement is more than the second setting duration;
If more than the second setting duration, then by the sub-frame resources in the use of net node of described off-grid from determination
It may happen that in the sub-frame resources of collision remove;If being not above the second setting duration, then by described de-
The sub-frame resources using at net node of net is still defined as it may happen that the sub-frame resources collided.
Specifically, described base station is receiving at net node by being converted to enter at net node for off-grid node before
The sub-frame resources information currently taking reporting during row network insertion;Can be according to the described son currently taking
Frame resource information, the described interference instruction information of reception, determine and report the sub-frame resources information currently taking
Identical with the sub-frame resources that off-grid node uses at net node;Afterwards can be by currently taking to described reporting
Instruction information is collided in issuing at net node of sub-frame resources information;And report, described in receiving, the son currently taking
The optional idle sub-frame resources information sending at net node of frame resource information;And combine described optional idle son
Frame resource information, from whole sub-frame resources except it may happen that collision sub-frame resources in addition to and be not allocated to
Other select at least one sub-frame resources in the sub-frame resources of net node, be handed down to described in report and currently take
Sub-frame resources information this series of process of net node complete to report currently take subframe money
The resource distribution at net node of source information.
More specifically, can be by timer and off-grid be judged to the mark of sub-frame resources, use off-grid
Frame timer determine respectively prediction will off-grid at net node whether off-grid and the need of by
Off-grid the sub-frame resources that net node takies from it may happen that collision sub-frame resources remove, off-grid is sentenced
The timing length determining timer is set to the described first setting duration, by the timing length of off-grid subframe timing device
It is set as the described second setting duration.When base station judge certain net node as potential off-grid at net node when,
In the currently used sub-frame resources of net node, this is labeled as off-grid sub-frame resources, and base station is covering model for self
Also need to the impact in view of off-grid sub-frame resources when net node distribution sub-frame resources (for self in enclosing
Coverage and off-grid node region have and this subframe can not be used to provide at net node in mutual scope
Source), open off-grid simultaneously and judge timer, before off-grid judges timer expiry, if having received again
In the information (such as TA, reporting position and channel measurement amount etc.) of net node, then off-grid is judged timing
Device is cancelled, and it is invalid to be set to the off-grid sub-frame property of this sub-frame resources.Otherwise, then may determine that described at net
Node off-grid.For be determined off-grid at net node, the sub-frame resources taking it opens off-grid
Subframe timing device, when off-grid subframe timing device has not timed out, for saving at net in own coverage area
The impact in view of off-grid sub-frame resources is needed during point distribution sub-frame resources.When off-grid subframe timing device time-out
After, the off-grid attribute of this sub-frame resources is cancelled, namely needs the subframe money taking at net node of off-grid
Source is from it may happen that remove the sub-frame resources of collision.
Below by a specific example, said process is illustrated:
Assuming that node A is off-grid node, node B, node C, node D are at net node.Base station is
Node B, node C are respectively allocated sub-frame resources 1 and sub-frame resources 2, and node B, node C need the cycle
Property is that base station reports the geographical location information of oneself, simultaneously when strong jamming being detected, also reports base station.
Assuming that the cycle of reporting position is 3s.
For node B, report the positional information of oneself in (x) s moment, in (x+3) s moment base station not
Having and receiving the positional information that node reports, base station is according to the historical information of node B, the rail to node B
The renewal of giving a forecast property of mark.Reach base station in (x+6) s moment and be still not received by the position that node B reports
Confidence ceases, and further base station combines the positional information of node B or D2N link measurement amount and edge net
Road coverage condition, determines that node B may off-grid.The subframe 1 taking node B is labeled as off-grid
Subframe, needs the impact in view of this off-grid subframe in this cell during other nodes distribution sub-frame resources,
Such as the node in distance cell edge certain distance all can not multiplexed sub frame 1.Open off-grid and judge timing
Device, this timer duration 3s, reach when (x+9) s moment, base station is interior without receiving node during this period
Any information reporting of B, it is determined that node B off-grid.Open off-grid subframe timing device, configure this fixed
When device duration 9s (this timing is that the mobility according to node and interference region size are arranged), de-
Before net frame timer time-out, need in view of off-grid during other nodes distribution sub-frame resources in this cell
The impact of sub-frame resources.
After 9s, the off-grid attribute of this subframe lost efficacy, and base station is for when net node distribution subframe, can being somebody's turn to do
Subframe 1 is distributed at net node, it is assumed that base station is allocated to node D.After a period of time, at net node
C detects strong jamming in subframe 1, at subframe 2 (base station is the sub-frame resources that node C distributes) node C
Reporting base station, base station knows that subframe 1 there occurs that subframe is collided, and takies in conjunction with subframe and geographical position letter
Breath is analyzed, and the node in base station predicate node D and a non-cell collides.In this mode
Under, in order to ensure to distribute the validity of resource, base station is that node sends selection idle subframe instruction, node D
After receiving this selection idle subframe instruction, carry out bottom monitoring and measurement, select 3 candidate's subframes,
It is that the sub-frame resources that node distributes reports base station in base station, base station is determined final subframe, and passes through
Control channel distributes to node D.
