Description
Technical field
The present invention relates to communication technical field, the decision method and device of a kind of resource collision are particularly related to.
Background technology
3GPP RAN1#84bis meeting conclusions are：Control information SA and data message data only determines it is frequency division multiplexing FDM
Mode, also without determining that SA and the data that it is associated are same subframe or different subframes, specific SA resource pools and data resource pool
Between relation also have not determined.It can think that specific structure and incidence relation have not determined between SA and data.
Here some simply illustrative figures of specific structure between SA and data are provided：SA and data time division multiplexing tdms
Or frequency division multiplexing FDM.It is the schematic diagram of SA and data under time division multiplexing mode as shown in Figure 1.On time-multiplexed mode,
Fig. 1 is only one simply illustrative, in a frame, may there was only one data resource pool of a SA resource pool, it is also possible to multiple
The multiple data resource ponds of SA resource pools；But SA resource pools and data resource pool are pure TDM modes.It is existing such as in V2X bandwidth
SA resource pools, there is data resource pond again, then are that SA/ data are frequency division multiplexing FDM (with the mode of subframe).
On SA and the data that associate whether with subframe judgement, if as shown in Fig. 2 when SA message indicates, not only
Currently transmitted packet resource information is contained, i.e., in addition to comprising current data packet resource information, also comprising other number
According to bag resource (than the resource of next packet as shown in Figure 2, the instruction of " M+1 " individual bag is contained in SA1), or only
When only including the resource information of next packet, in this case, referred to as SA is in different subframes with the data associated.
, whereas if the instruction of current packet resource is only included, such as the only instruction of the resource comprising m-th business packet in SA1
If, then referred to as SA and the same subframe of the data associated.
Under FDM modes, SA resource pools have two kinds of structures for SA and data, and one kind is sideband, is exactly the both sides of whole frequency band
Or the resource on one side is to be used for SA resource pools, Fig. 3 gives a kind of diagram.Another is adjacent band, is exactly in whole bandwidth,
Each data SA resources corresponding with its are adjacent on frequency band, i.e., on whole V2X frequency spectrum resources, be divided into it is multiple from
Scattered SA resource pools and data resource pool.Here we discuss a kind of special construction of sideband mode, and SA and data are mappings
(mapping) mode.Assuming that there is certain corresponding relation, i.e. a node selection between SA subbands and data subband
Resource is sent on a data resource, then must send SA in SA sub-band resources corresponding to the data resource.Certainly here
SA subbands and the size of data subband be different.Fig. 4 gives a kind of mapping of the SA resources under the sideband mode on one side
Schematic diagram.Conversely, the mode of fixed mapping is not present in SA and data, it is exactly to also need to provide SA after node selects data resource
Source is selected, or also needs to select data resource after selection SA resources.Here priority simply implements
When, it is that first which resource is selected, no essential distinction.
The trigger condition of some resource gravity treatments is given in 3GPP RAN1#84bis meeting conclusions：Actively touched including open loop
The gravity treatment of hair resource, node decode reception by SA decoding and judge that gravity treatment and third party's node are anti-after oneself colliding
Feedback resource collides node resource gravity treatment for causing to collide etc..It is specific at present to judge for this several trigger condition
Flow does not determine also.

Embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
It should be noted that resource is probably unsuccessfully caused by being disturbed due to two classes：1) co-channel interference, spatial reuse is caused
Resource collides, resource failure；2) with interior leakage, cause the resource of frequency division that strong jamming occurs.It is provided in an embodiment of the present invention
The decision method of resource collision considers the judgement to the interference of above-mentioned two class so as to increase the accuracy of judgement.
First embodiment
As shown in figure 5, the first embodiment of the present invention provides a kind of decision method of resource collision, using one the 3rd section
Point, the transmission of data message that the transmission of the control information of business packet association associates with the business packet are located at identical subframe, institute
Stating decision method includes：
Step 51, whether the decoding for the control information that detection receiving node pair associates with business packet succeeds；
Step 52, if successfully decoded to control information, the number that the receiving node pair associates with the business packet is detected
It is believed that whether the decoding of breath succeeds；
Step 53, if the decoding to data message fails, determine money on the data resource that the data message takes be present
Collide in source；
Step 54, resource collision be present on the data resource taken to receiving node and sending node feedback data information
First result.
In the first embodiment of the present invention, control information SA and data message data position are not required, i.e., it is unlimited
Surely it is mapping mapping using SA and data, i.e., with subframe pattern, the SA and data of node position are arbitrary.This hair
In bright first embodiment, for any one node, the Data resources of interference and his occupancy in the SA resources that he takes
On interference it is often different, so, for receiving node, in the SA resources of successfully decoded interference and SA instruction
Interference in corresponding data resources also tends to be different.
Specifically, decision procedure 1 is：SA successfully decodeds, and the corresponding data decoding failures of SA instructions, due to transmitting-receiving
What the distance between node was to determine, the disturbed condition on SA and data is often different, and SA successfully decodeds and data are solved
Code failure, then it is considered that there occurs strong jamming on data, that is, judge to be collided on the data resource of data occupancy；Pass through
After third party's node realizes the judgement of resource collision, result of determination can be sent to transmission section by third party's node in the present embodiment
Point and receiving node, so that sending node and receiving node can determine whether resource collides.
Further, decision method also includes described in the first embodiment of the present invention：
Step 54, if successfully decoded to data message, according to the measurement of the data resource taken to the data message
As a result, determine to whether there is resource collision on the data resource that the data message takes.
Specifically, step 54 includes：
When step 541, to the successfully decoded of data message, the data resource taken to the data message measures,
Determine the jamming power of the data resource；
Step 542, if the jamming power is more than the first pre-determined threshold, the data resource that the data message takes is determined
On the possibility of resource collision be present and may be deposited on the data resource that is taken to receiving node and sending node feedback data information
In the 3rd result of resource collision；If the jamming power is less than or equal to first pre-determined threshold, the data are determined
Resource collision and the number taken to receiving node and sending node feedback data information are not present on the data resource that information takes
According to the second result that resource collision is not present in resource.
That is decision procedure 2：SA successfully decodeds, and the corresponding data decodings of SA instructions also succeed, by data portions
Point measurement judged：Due to data successfully decodeds, it can determine that the resource that data takes whether there is by data measurements
Strong jamming；The jamming power for the data resource that the data message takes is can obtain by data measurements first, so as to according to dry
Disturb power and determine that data resource whether there is resource collision.Specifically, when the jamming power of the data parts by being calculated
More than the jamming power thresholding being pre-configured with, then it is assumed that although the data resource that the data takes can be demodulated correctly, still
The possibility of collision so be present；When the jamming power by the data parts being calculated is less than the jamming power door being pre-configured with
Limit, then it is assumed that collision is not present in it.
Specifically, the calculation procedure of jamming power includes in step 541：
When step 5411, to the successfully decoded of data message, the data resource taken to the data message measures,
Obtain connecing on the data resource pond that all data messages take in the signal power on the data resource and same subframe
Receive general power；
Step 5412, according to the number that all data messages take in the signal power on the data resource and same subframe
According to the reception general power on resource pool, the jamming power of the data resource is determined.
That is the jamming power of data resource, equal to connecing on the data resource pond that all data messages take in same subframe
Receive the difference of the signal power on the data resource of general power and data message occupancy.
It should be noted that in the decision method for the resource collision that the first embodiment of the present invention provides, decision procedure 2 is more
It is adapted to Data resources to have under pattern modes.Here data has pattern to refer to：Resource is completely orthogonal, between node
Do not touch, otherwise touch entirely.Data refers to that resource is nonopiate without pattern.Then from the perspective of interference, it is transmitted several times
Between, disturbed condition all may be different.
To sum up, the SA decoded informations of foundation are aided in the survey in whole data resource pond simultaneously in the first embodiment of the present invention
(corresponding data resources are successfully decoded comprising SA, and other parts (can be regarded as corresponding to non-successful decoding SA in amount
Data resources and idling-resource)) structure that most matches of this mechanism is：SA and data is same subframe, and SA and data are not
It is required that mapping.And the processing and maintenance for the measurement increase collision status for passing through control information, give and sentenced according to third party's feedback
Determine the concrete implementation mode of resource collision, there is realizability.
Explanation is needed further exist for, when node carries out resource selection, for the resource for judging to collide, because not
Understand the release conditions of next cycle node, neither consider to be multiplexed with the collision resource space, also do not consider and resource frequency
Divide multiplexing.The resource in the subframe where the collision resource is not considered.
Second embodiment
As shown in fig. 6, the second embodiment of the present invention provides a kind of decision method of resource collision, the control of business packet association
The transmission for the data message that the transmission of information processed associates with the business packet is located at identical subframe, resource that control information takes and
The resource that data message takes has mapping relations, and the decision method includes：
Step 61, whether the decoding for the control information that detection receiving node pair associates with business packet succeeds；
Step 62, if the decoding to control information fails, the control money that all control information take in same subframe is obtained
Reception general power on the pond of source, when the reception general power is more than the second pre-determined threshold, it is determined that associated with the business packet
Resource collision be present on the data resource that data message takes；
Step 63, resource collision be present on the data resource taken to receiving node and sending node feedback data information
First result.
It is the message structure for needing to use SA and data to be mapping mapping in the second embodiment of the present invention.It is such
Words, in this manner, for any one node, the Data of interference and his occupancy in the SA resources that he takes interference
It is the same, so, for receiving node, in the corresponding data resources that interference and SA in the SA resources of successfully decoded indicate
Interference and the same, receiving node can substitute the disturbed condition on corresponding data with the disturbed condition on SA.
SA and data is under mapping message structure, and the disturbed condition in the resource can be obtained by SA measurement,
Carry out the disturbed condition in Data resources corresponding to equivalent substitution.
Specifically, decision procedure 3 is：SA decodings failure (fails, can not continue to decode data) because SA is decoded,
And the reception general power on the control resource pool that all control information take in same subframe exceedes certain thresholding, under the conditions of being somebody's turn to do,
It can be determined that there occurs resource collision in data resources.It is analyzed as follows：Reception general power in the SA resources of measurement exceedes certain
The reason for thresholding then thinks that the geographic distance between transmitting-receiving node is closer, and decoding fails is that there occurs strong jamming.Due to SA
Disturbed condition and data be the same, it can be considered that being equally that there occurs strong jamming collision in data resources.And pass through
After third party's node realizes the judgement of resource collision, result of determination can be sent to transmission section by third party's node in the present embodiment
Point and receiving node, so that sending node and receiving node can determine whether resource collides.
Further, the decision method of second embodiment of the present invention offer resource collision also includes：
Step 63, if successfully decoded to control information, the control resource taken to the control information measures
Jamming power onto the control resource；
Step 64, if the jamming power is more than the 3rd pre-determined threshold, it is determined that the data message associated with the business packet
The possibility of resource collision and the number taken to receiving node and sending node feedback data information on the data resource of occupancy be present
According to the 3rd result that resource collision is there may be in resource；If the jamming power is less than or equal to the 3rd pre- gating
Limit, it is determined that on the data resource that the data message that associate with the business packet takes in the absence of resource collision and to receiving node and
The second result of resource collision is not present on the data resource that sending node feedback data information takes.
That is decision procedure 4：SA successfully decodeds, data disturbed condition is predicted by the measurement result to SA.It is first
The jamming power that the control resource that the control information takes is can obtain to SA measurements is first passed through, when the SA portions by being calculated
The interference power values divided are more than the jamming power thresholding being pre-configured with, then it is assumed that although the sa resources can be demodulated correctly, deposit
In the possibility of collision.Because SA disturbed condition and data are the same, it is therefore contemplated that being equally existed in the data resources
The possibility of collision；When being less than the jamming power thresholding being pre-configured with by the jamming power for the SA parts being calculated, then recognize
Collision is not present for SA resources.Because SA disturbed condition and data are the same, it is therefore contemplated that same in the data resources
Collision is not present in sample.
Specifically, the calculation procedure of jamming power includes in step 63：
When step 631, to the successfully decoded of control information, the control resource taken to the control information measures,
Obtain connecing on the control resource pool that all control information take in the signal power in the control resource and same subframe
Receive general power；
Step 632, according to the signal power in the control resource and the reception general power, the control resource is determined
Jamming power.
The jamming power of resource is controlled, equal to connecing on the control resource pool that all control information take in same subframe
Receive the difference of the signal power in the control resource that general power and the control information take.
It should be noted that the decision procedure 4 has pattern mode more suitable for data.Here data has pattern
Refer to：Resource is completely orthogonal, otherwise do not touched between node, otherwise touch entirely.Data refers to that resource is anon-normal without pattern
Hand over.Then from the perspective of interference, between being transmitted several times, disturbed condition all may be different.
Further, the decision method that the second embodiment of the present invention provides also includes：
Step 65, if successfully decoded to control information, the number that the receiving node pair associates with the business packet is detected
It is believed that whether the decoding of breath succeeds；
Step 66, if the decoding to data message fails, the signal power in the control resource that control information takes is obtained；
Step 67, if the signal power in the control resource that the control information takes is more than the 4th pre-determined threshold, it is determined that
Resource collision on the data resource that the data message that is associated with the business packet takes be present and to receiving node and sending node
The first result of resource collision on the data resource that feedback data information takes be present；If the control money that the control information takes
Signal power on source is less than or equal to the 4th pre-determined threshold, it is determined that the data message associated with the business packet takes
Data resource on resource collision is not present and on the data resource that is taken to receiving node and sending node feedback data information
In the absence of the second result of resource collision.
That is decision procedure 5：On the premise of SA successfully decodeds, data decoding failures, and the signal power in SA resources exceedes
Certain thresholding：Under the conditions of being somebody's turn to do, it is possible to determine that there occurs resource collision in data resources.It is analyzed as follows：Simple SA successfully decodeds,
The situation of data decoding failures is existing, and is consistent with disturbed condition in data resources because of SA resources, substantially may be used
To think spatial reuse resource collision does not occur.It is that SA solutions possible occur and SA decoding ranges are greater than Data
Code success, and data decoding failures.And in the case that the signal power on SA exceedes certain thresholding, it is believed that transmitting-receiving section
The distance between point relatively, in this manner, if data decodings fail, may infer that there occurs in stronger band
Leakage, i.e., there occurs resource collision in data resources.
To sum up, aided in simultaneously with the measurement of whole SA resource pools according to SA decoded informations in the second embodiment of the present invention
The structure that (the SA parts comprising the SA that is successfully decoded and non-successful decoding) this mechanism most matches is：SA and associated
Data is the judgement that same subframe and SA and data have resource collision under this channel architecture under certain mapping modes.And pass through
The processing and maintenance of the measurement increase collision status of control information, give according to the specific of third party's feedback and judge resource collision
Implementation, there is realizability.
Explanation is needed further exist for, when node carries out resource selection, for the resource for judging to collide, because not
Understand the release conditions of next cycle node, neither consider to be multiplexed with the collision resource space, also do not consider and resource frequency
