Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out Describe.

The embodiment of the invention discloses a kind of resource detection method and communication equipment, it is possible to avoid Radio Resource Resource contention in pond.In order to be better understood from the embodiment of the present invention, the most first to the embodiment of the present invention Application scenarios is described.

Refer to Fig. 1 and Fig. 2, as shown in Figure 1 or 2, between communication equipment, share Radio Resource pond, nothing Line resource pool includes multiple Radio Resource, and Radio Resource pond shown in Fig. 1 includes Radio Resource 1～Radio Resource N.Radio Resource described herein be optionally included with physical resource (frequency domain resource and/or time Territory resource) or logical resource (channel resource).One physical resource can take certain time interval and frequency Rate scope, i.e. running time-frequency resource.In FIG, the Radio Resource pond shared between communication equipment is predefined Radio Resource pond, as between current two communication equipments, communication frequency can be predefined in 500MHZ～6GHZ scope In, this scope can be predefined by wireless communication standard group or communication manufacturer.In fig. 2, communication equipment it Between the Radio Resource pond that configured by network equipment, Radio Resource pond shared, if network equipment is it Communication frequency in the range of communication device configured 500MHZ～6GHZ.Communication equipment can lead within the range Information transmission is carried out in letter frequency.As shown in Figures 1 and 2, communication equipment 1 communicates each other with communication equipment 3 Opposite end, communication equipment 2 and communication equipment 4 Correspondent Node each other, i.e. communication equipment 1 are carried out with communication equipment 3 Information is transmitted, and communication equipment 2 and communication equipment 4 carry out information transmission.Above-mentioned 4 communication equipments are shared wireless Radio Resource in resource pool.When communication equipment 1 needs to transmit information to communication equipment 3, communication equipment 1 Information transmission can be carried out from main separation or the Radio Resource being configured in Radio Resource pond；With Reason, communication equipment 2 needs when communication equipment 4 transmits information, it is possible to from main separation or be configured to A Radio Resource in Radio Resource pond carries out information transmission.Certainly, the applied field shown in Fig. 1 Yu Fig. 2 , can there is multiple other and unillustrated communication equipment and share this Radio Resource pond in Jing Zhong, should along with sharing The communication equipment in Radio Resource pond gets more and more, and inevitably resource contention will occur, such as Fig. 1 and Fig. 2 Shown in, when communication equipment 1 with communication equipment 2 simultaneously need to during the information of carrying out transmission, communication equipment 1 with communicate Equipment 2 all have selected or be both configured to access Radio Resource 1, now, causes resource contention.Resource is rushed The prominent communication reliability being likely to result in communication equipment 1 or communication equipment 2 declines, or is also possible to cause Communication blocking, or communication equipment cannot be carried out information transmission.

It should be noted that the communication equipment in application scenarios and described by following example can include wireless Terminal unit, as user terminal includes mobile phone, panel computer, personal digital assistant etc., and for example Internet of Things In D2D (Device to Device) device, as included V2V (Vehicle to Vehicle) terminal etc.； Communication equipment may also include base station, such as small base station etc..When communication equipment is wireless terminal device, net Network side apparatus can be base station；When communication equipment is base station, network equipment can be base station control device, This base station control device is for distributing a Radio Resource pond for base station.

In conjunction with the application scenarios shown in Fig. 1 and Fig. 2, see Fig. 3, Fig. 3 is disclosed in the embodiment of the present invention The process schematic of same Radio Resource competed by a kind of multiple communication equipments.Fig. 3 with two communication equipments is Example, respectively communication equipment 1 and communication equipment 2.Wherein, communication equipment 1 or communication equipment 2 are competed wireless The method of resource 1 can be found in Fig. 4.

It should be noted that the communication equipment shown in figure 3, it is provided with full duplex ability.The present invention is real Executing the full duplex in example and be different from time division duplex or FDD, here, full duplex is capable of same Receive and send messages on one Radio Resource (same running time-frequency resource or same channel) simultaneously, and time division duplex is only Being capable of receiving in same resource or one in transmission information, FDD is only capable of realization not With receiving in resource or transmission information simultaneously.

Referring to Fig. 4, Fig. 4 is the schematic flow sheet of a kind of resource detection method disclosed in the embodiment of the present invention. The method is applied to communication equipment 1 or communication equipment 2, and the embodiment of the present invention is as a example by communication equipment 1.Such as figure Shown in 4, the method can comprise the following steps.

Step S401, communication equipment 1 determines the unappropriated Radio Resource 1 in Radio Resource pond.

Optionally, communication equipment 1 can configuration based on network equipment or pre-based in communication equipment 1 Establishing is put and is determined unappropriated Radio Resource 1 in Radio Resource pond；Or communication equipment 1 also can be by visiting Surveying Radio Resource 1 the most idle, if it is idle to detect Radio Resource 1, then communication equipment 1 can determine that wireless money Source 1 is unoccupied.Wherein, Radio Resource pond can include multiple Radio Resource, and the plurality of Radio Resource can be The Radio Resource that one or more network equipments are configured, it is possible to for multiple communication equipments share wireless Resource, and the plurality of Radio Resource includes Radio Resource 1, optionally, in the plurality of Radio Resource also The Radio Resource 2 etc. becoming mapping relations with Radio Resource 1 can be included.It should be noted that communication equipment 1 can First pass through unappropriated Radio Resource 1 in confirmation Radio Resource pond, after confirming this Radio Resource 1, This Radio Resource 1 accessible takies or competes this Radio Resource 1 further to send detection information.

Concrete, when the communication system residing for communication equipment 1 exists network equipment, as shown in Figure 2 Application scenarios in, network equipment can be the wireless money in communication equipment 1 allocation radio resource pond in advance Source, as communication equipment 1 allocation radio resource 1.When there are data to be sent in communication equipment 1 or logical Letter equipment 1 need to its Correspondent Node (communication equipment 3) send data time, confirm Radio Resource 1 not by After taking, acquiescence is according to the moment being arranged in configuration instruction or the moment access nothing arranged with communication equipment 3 Line resource 1, certainly, now, if communication equipment 2 is also carried out radio-resource-configuration by above-mentioned network equipment, Radio Resource or the access Radio Resource of acquiescence that communication equipment 2 is configured are alternatively Radio Resource 1.Or, Can store preset configuration in communication equipment 1 in this equipment, this preset configuration is used for indicating communication equipment 1 to need During data to be sent, the Radio Resource that communication equipment 1 has access to.Certainly, above two mode, communication Equipment 1 can be configured multiple Radio Resource access interface by the configuration of network equipment or preset configuration, logical May select in multiple Radio Resource one accesses letter equipment 1, and the embodiment of the present invention is with Radio Resource 1 As a example by.

Or, whether idle communication equipment 1 also by the side of the Radio Resource in detection wireless resource pool Formula, determines that the Radio Resource that communication equipment 1 is to be accessed is the most occupied.As competed net when communication equipment 1 During Radio Resource failure that is that network side configures or that be pre-configured with, or when communication equipment 1 needs to communication equipment 3 When sending data, communication equipment 1 can be the most idle by the Radio Resource in detection wireless resource pool, if visiting When measuring Radio Resource 1 free time in Radio Resource pond, i.e. detection moment Radio Resource 1 is not led to by other During letter hold facility, it is determined that Radio Resource 1 is unoccupied, and then communication equipment 1 can be accessed by this wireless money Source 1.

Step S402, communication equipment 1 is sent by Radio Resource 1 in time window and is used for competing described first The detection information of Radio Resource.

In one embodiment, after communication equipment 1 determines unappropriated Radio Resource 1, can be in the time Send the detection information for competing Radio Resource 1 by this Radio Resource 1 in window, with further detection be Radio Resource 1 competed by the no communication equipment having other simultaneously.Wherein, time window described herein is One continuous print period, the window length of this time window determines the message length of detection information.At this time window In, i.e. in regular hour length, communication equipment sends detection information by Radio Resource 1.

Optionally, a kind of situation is the Radio Resource that Radio Resource 1 is broader bandwidth that communication equipment accesses, Can allow for communication equipment and send data by Radio Resource 1.Another kind of situation is the nothing that communication equipment accesses Line resource 1 can be the Radio Resource of narrower bandwidth, is only capable of and meets communication equipment transmission such as the numbers such as detection information According to the information that amount is less, Radio Resource 1 can be associated with other Radio Resources in Radio Resource pond, shape Becoming mapping relations, the embodiment of the present invention is as a example by Radio Resource 2, and Radio Resource 2 becomes to map with Radio Resource 1 Relation, and the bandwidth of Radio Resource 2 is bigger, it is possible to allow communication equipment to send data；If communication equipment Radio Resource 1 can be competed, then show that communication equipment can be competed Radio Resource 2 and send data, institute State the Radio Resource 2 that communication equipment can use Radio Resource 1 to be mapped to.

Optionally, when communication equipment 1 is when determining the starting point of the time window sending detection information, this time The starting point of window can be the moment that communication equipment 1 detects Radio Resource 1 free time, the starting point of this time window The time point that can send information also dependent on default agreement is determined.Concrete, if communication equipment 1 When there is the network equipment configuring communication equipment 1 in the communication system at place, communication equipment 1 can Determining whether network equipment is configured with the starting point of above-mentioned time window, i.e. this communication equipment 1 can be based on this net When the transmission subframe that can communicate of communication equipment 1 of network side apparatus configuration or the sart point in time of time slot determine Between the sart point in time of window, and then, it is determined that send the start time point of detection information.Or, if logical The communication system at letter equipment 1 place does not has network equipment, or network equipment is not in communication equipment 1 When the start time point of time window configures, then communication equipment 1 communicates with opposite end (communication equipment 3) Between need by other ad hoc fashions determine transmission the period, as by GPS (Global Navigation Satellite System, GNSS) or global positioning system (Global Positioning System, GPS) transmission time of accurate communication equipment 1 such that it is able to realize communication equipment 1 and set with communication Standby 3 realize sending Tong Bu with reception, or communication equipment 1 according to receive from other communication equipments The synchronizing time point that lock in time produces, or the synchronizing time point that communication equipment 1 self produces, certainly, Network equipment is alternatively communication equipment 1 and configures synchronizing time point, as configured GNSS time for communication equipment 1 Point or gps time point are as the starting point of time window.

Optionally, the window length of time window can be determined by many kinds of parameters, due to the independence of each communication equipment, It parameter possessed is the most different, and then affects the time window sending detection information in each communication equipment Window length is different.The window length of the time window in communication equipment 1 can be by the one-tenth of the history competitive resource of communication equipment 1 The parameters such as the data volume of the data to be sent in merit probability, communication equipment 1 determine.As communication equipment 1 is being gone through The probability of success of history competitive resource is the lowest, then the window length of the time window that communication equipment 1 needs is the longest；And for example lead to The data volume of the data to be sent in letter equipment 1 is the biggest, then the window length of the time window that communication equipment 1 needs is more Long.

Illustrating, when having data to be sent in communication equipment 1, communication equipment 1 can communicate with other and set Radio Resource in standby competition Radio Resource pond, if this Radio Resource failure competed by communication equipment 1, then can fit When the window of the time window adjusted in communication equipment 1 is long, as long in increased window, to prepare to compete wireless money next time Source, if communication equipment 1 failure continuously when competing Radio Resource, the window of the most sustainable increase time window is long, Until competition is to Radio Resource.Certainly, communication equipment also by statistics competitive resource the probability of success, And the probability of the competition successful resource according to statistics, determine that the time window window of this competition Radio Resource 1 is long, It is greater than statistics as counted the window length that probability is time window determined by 25% of history competition successful resource The probability going out history competition successful resource is that determined by 75%, the window of time window is long, i.e. history is competed and successfully provided The probability in source and the window of time window grow up to negative correlativing relation, and such as negative sense linear relationship, negative sense is non-linear Dependency relation etc..Negative correlativing relation shows that the probability of history competition successful resource is the lowest, then the window of time window The longest；The probability of history competition successful resource is the highest, then the window length of time window is the shortest.

In like manner, in communication equipment 1, the size of data volume to be sent also can grow up to positive correlation pass with the window of time window System, the size of data volume the most to be sent is the biggest, and the window length of time window is the longest.The size of data volume to be sent Positive correlation can be grown up to the window of time window.

Optionally, the window length set of the predeterminable time window of communication equipment 1, window length set includes multiple presetting Conventional time window window long.

Specifically can be found in table 1～table 2.As shown in table 1, the data volume of the data to be sent in communication equipment 1 can With cache size numeric representation, this numerical value unit is byte (byte), the window length of time window withRepresent, Unit is microsecond (μ s).

Table 1

As shown in table 2, the probability of success of the history competitive resource of the statistics in communication equipment 1 represents with SR, The window length of time window withRepresent.

Table 2

Optionally, in communication equipment 1, the window length of time window can be combined really by the many kinds of parameters in above-mentioned parameter Fixed, as in communication equipment 1, the window length of time window can have the probability of success of history competitive resource and to be sent simultaneously Data change storage and other parameter determinations, then the weighted value that determine parameter can be determined in advance, due to each really Determine time window determined by parameter different, in conjunction with each weighted value size determining parameter, can calculate comprehensive The window of the time window closed is long.

In one embodiment, communication equipment 1 can include detection by the detection information that Radio Resource 1 sends Data or detection sequence.Wherein, detection sequence may be used to represent that this detection sequence is sent by communication equipment 1, The communication equipment that can make other monitoring wireless resources 1 knows that current communication devices 1 is utilizing Radio Resource 1 sends detection information, and would know that Radio Resource 1 competed by communication equipment 1.When communication equipment 1 sends During detection sequence, this detection sequence can include ZC (Zadoff-Chu) sequence, binary sequence, random One or more in sequence, level pulse.The detection data that communication equipment 1 sends can be communication equipment 1 In the parts of data to be sent, if communication equipment 1 can compete Radio Resource 1, then communication equipment can Continue to send the remainder in data to be sent, take full advantage of Radio Resource 1, certainly, detection data May also include other data, the embodiment of the present invention does not limits.

Step S403, when communication equipment 1 is when sending described detection information, listens to exist in time window Competition communication equipment is also at competition Radio Resource 1, and communication equipment 1 judges that communication equipment 1 is relative to competition communication Equipment whether can successful contention to Radio Resource 1.

In one embodiment, communication equipment 1, when sending detection information, can be supervised in the time window determined Listen Radio Resource 1, to determine whether that other communication equipments compete Radio Resource 1 with communication equipment 1 simultaneously. Owing to full duplex supported by communication equipment 1, communication equipment 1 can monitoring wireless money while sending detection information Source 1, wherein, the duration of monitoring wireless resource 1 is long less than or equal to the window of time window.It should be noted that Radio Resource 1 can persistently be monitored in time window by communication equipment 1, it is possible to according to default monitoring week Radio Resource 1 is monitored by phase or other modes.

Optionally, before communication equipment 1 monitoring wireless resource 1, communication equipment 1 can obtain Radio Resource 1 Bandwidth, and determine the first signal energy threshold value of communication equipment 1 according to the bandwidth of this Radio Resource 1. Concrete, determined by the first signal energy threshold value can become positive correlation with the bandwidth of Radio Resource 1. Optionally, the first signal energy threshold value can be calculated by below equation:

THRESHOLD=10 × log10 (BW (MHZ)/20 (MHZ)) (dBm)；Wherein, THRESHOLD represents First signal energy threshold value, BW represents the bandwidth of Radio Resource 1.MHZ (megahertz) represents bandwidth Measurement unit, dBm (dBm) represents the measurement unit of energy threshold.Certainly, the first signal energy Amount threshold value also can be calculated by other positive correlation formula, is not repeating at this.In addition, it is possible to pre- If the mapping relations table of the bandwidth of signal energy threshold value and Radio Resource 1, as different bandwidth ranges is corresponding One signal energy threshold value etc., then communication equipment 1 can be pre-from this by obtaining the bandwidth of Radio Resource 1 If mapping relations table in call a corresponding signal energy threshold value as the first signal energy door Limit value.Owing to now communication equipment 1 sends detection information, therefore, when communication equipment 1 by Radio Resource 1 When monitoring wireless resource 1, can obtain the reception signal energy on this Radio Resource 1, communication equipment 1 also may be used Calculate the signal energy of sent detection information, and by calculating doing relative to communication equipment 1 Disturbing the difference that signal energy is the signal gross energy on Radio Resource 1 and the signal energy of detection information, communication sets Standby 1 by monitoring whether interference signal energy is more than the first signal energy threshold value determined, with monitoring wireless Whether resource 1 is taken by competition communication equipment simultaneously.In the embodiment of the present invention, send the competing of interference information Striving communication equipment is communication equipment 2.When communication equipment 1 listens to disturb signal energy more than first determined Signal energy threshold value, then show that communication equipment 1 listens to Radio Resource 1 and taken by competition communication equipment, If competition communication equipment send for detection sequence, this detection sequence can be resolved, know that communication equipment 2 also exists Take Radio Resource 1 simultaneously.When communication equipment 1 listens to disturb signal energy to be less than the first signal determined Energy threshold, then show that communication equipment 1 determines do not have other communication equipments to take Radio Resource 1.

Optionally, communication equipment 1 monitoring wireless resource 1 whether taken by competition communication equipment simultaneously another The mode of kind is the bandwidth that communication equipment 1 obtained Radio Resource 1 before monitoring wireless resource 1, and according to communication Signal energy and this bandwidth of the detection information that equipment 1 sends determines secondary signal energy threshold, wherein, The determination mode of secondary signal energy threshold can be reflecting by Radio Resource 1 and signal energy threshold value Penetrate relation, determine the first signal energy threshold value, and calculate the signal energy of detection information, Secondary signal energy threshold can be the signal energy sum of the first signal energy threshold value and detection information. Or, determined and the second letter by the bandwidth synthesis of the signal energy of detection information Yu the Radio Resource 1 of acquisition The mapping relations of number energy threshold, such as default mapping relations table etc., then communication equipment 1 can be according to concrete The bandwidth of the Radio Resource 1 of the signal energy of detection information and acquisition calls corresponding secondary signal energy Amount threshold value.Due to this secondary signal energy threshold it is contemplated that the signal energy of detection information, because of This, communication equipment 1 can the direct reception signal energy in monitoring wireless resource 1, if this reception signal energy More than secondary signal energy threshold, then communication equipment 1 can determine that listening to Radio Resource 1 is communicated by competition Equipment takies simultaneously；If this signal gross energy is less than secondary signal energy threshold, then communication equipment 1 can be true Surely other communication equipments are not had to take Radio Resource 1.

Optionally, communication equipment 1 by determining by the way of carrying out detection sequence coherent detection in time window is No have other communication equipments to compete Radio Resource 1 simultaneously.Concrete, if other communication equipments are by wireless money When the detection information that source 1 sends is detection sequence, communication equipment 1 is by resolving Radio Resource 1 in time window In detection sequence, it may be determined that specifically take Radio Resource 1 competition communication equipment number.By we Formula communication equipment 1 can know the concrete condition of the competition communication equipment taking Radio Resource 1 more accurately. Further, owing to communication equipment is when resolving the detection sequence in Radio Resource 1, this spy can be obtained simultaneously The sequence energy of order-checking row, and determine whether that the communication sending this detection sequence sets according to this sequence energy The standby competition communication equipment that whether can become communication equipment 1, illustrates, if the sequence of the detection sequence resolved Row energy attenuation is more serious, and energy is less than predetermined threshold value, then send the communication equipment of this detection sequence not The competition communication equipment of communication equipment 1 can be become.If it should be noted that communication equipment 1 is by detection When sequence coherent detection is not detected by competing communication equipment, there are two kinds of situations: 1, competition communication equipment does not has There is a transmission detection sequence, 2, do not compete communication equipment.If system being arranged communication equipment be required to send Detection sequence, then can determine that based on coherent detection mode and do not compete communication equipment, if in system the most about Fixed, then communication equipment further determines whether to there is competition also by the mode that above-mentioned signal energy detects Communication equipment, here, the embodiment of the present invention does not limits.

It is the most competing that any one in by the way can determine whether there is competition communication equipment accurately Strive Radio Resource 1.

In one embodiment, listen to by the way there is competition in time window when communication equipment 1 After Radio Resource 1 competed by communication equipment simultaneously, communication equipment 1 need judge whether can successful contention to nothing Line resource 1.As it is shown on figure 3, as a example by the competition communication equipment of this competition Radio Resource 1 is communication equipment 2. Communication equipment 1 can in the following manner any one judge whether to compete Radio Resource 1.Need Illustrating, the mode that Radio Resource 1 is initiated competition by communication equipment 2 carries out information for taking Radio Resource 1 The transmission of (including detection information or data), i.e. communication equipment 2 send information again by Radio Resource 1.

(1), the detection information that sent by Radio Resource 1 of communication equipment 1 be detection sequence 1, if communication sets Standby 1 listens to communication equipment 2 in time window initiates competition, and communication equipment 1 simultaneously to Radio Resource 1 When being able to detect that the detection sequence 2 that communication equipment 2 is sent by Radio Resource 1, communication equipment 1 can pass through The precedence information of the communication equipment comprised in contrast detection sequence, determines communication equipment 1 and communication equipment 2 Priority.Wherein it is desired to explanation, the detection sequence bag that communication equipment 1 sends with communication equipment 2 Containing its precedence information.Concrete, predeterminable detection sequence and the mapping table of priority, different The corresponding different priority of detection sequence, according to the time different determined by above-mentioned parameter in communication equipment The window length of window can generate different detection sequences, and then corresponding different priority.

When communication equipment 1 can contrast the precedence information that detection sequence 1 comprises respectively with detection sequence 2, If communication equipment 1 contrasts precedence information 1 that the detection information 1 that communication equipment 1 sends comprises higher than communication During the precedence information 2 that the detection information 2 that equipment 2 sends comprises, then can determine that can be successful for communication equipment 1 Competition is to Radio Resource 1；On the contrary, if communication equipment 1 contrasts precedence information 1 and is less than precedence information 2, Then communication equipment 1 can determine that can not successful contention to Radio Resource 1, certainly, communication equipment 1 also can contrast Go out precedence information 1 identical with precedence information 2, then the communication being required for current competitive Radio Resource 1 sets Standby introduce second and take turns competitive way, i.e. next cycle or proceed in the time period with before described competing Strive similar operation.Concrete, can be found in the describing mode of embodiment illustrated in fig. 5.

In the embodiment of the present invention, if the priority that communication equipment 1 contrasts in detection sequence 1 is relatively low, then lead to Letter equipment 1 can exit the competition to Radio Resource 1 before the end of the time window in advance, saves communication and sets The time of standby 1 competition Radio Resource, and then improve communication equipment 1 and send the efficiency of data.

(2), communication equipment 1 monitoring wireless resource 1 in time window, if communication equipment 1 and communication equipment 2 Simultaneously competition Radio Resource 1, then communication equipment 1 monitoring wireless resource 1 start can find communication equipment The existence of 2, if communication equipment 1 listens to Radio Resource 1 in time window and continues by competition communication equipment (logical Letter equipment 2) take until the end time point of time window, and at least one prison at the end of time window In listening the cycle, monitoring wireless resource 1 is persistently taken by competition communication equipment (communication equipment 2), shows communication The duration that equipment 2 sends detection information is long compared with the duration that communication equipment 1 sends detection information, and then shows to lead to The window length of the time window in letter equipment 2 is long more than the window of the time window in communication equipment 1, then communication equipment 1 is true Surely Radio Resource 1 can not be competed；If a certain moment that communication equipment 1 is in time window begins listening for Do not compete communication equipment and take Radio Resource 1, then show that communication equipment 2 exits competition Radio Resource 1, enter And communication equipment 1 can determine that and can compete Radio Resource 1, it is of course possible to there is communication equipment 1 in the time Listen to communication equipment 2 in window and persistently take Radio Resource 1, and at least one at the end of time window Listen to the vacant Radio Resource of communication equipment 21, i.e. Radio Resource 1 in listening period do not set by competition communication For taking, then communication equipment 1 can determine that communication equipment 1 is identical with the window length of the time window of communication equipment 2, enters And communication equipment 1 is identical with the priority of communication equipment 2, needing to carry out second and take turns resource contention, communication sets Standby 1 second take turns resource contention determines whether can successful contention to the concrete judgment mechanism of Radio Resource 1 Can be found in the step in embodiment illustrated in fig. 5, i.e. next cycle or proceed in the time period with before The operation that described competition is similar.

It should be noted that communication equipment 1 is when monitoring wireless resource 1, it may be determined that listen to multiple (such as N Individual) competition communication equipment take Radio Resource 1, communication equipment 1 monitoring wireless in by time window simultaneously During resource 1, the window length of some the communication contention equipment likely time windows in N number of competition communication equipment is shorter than The window of the time window in communication equipment 1 is long, exits resource contention the most in advance, if communication equipment 1 is in the time Listen to still suffer from M competition communication equipment in window and persistently take Radio Resource 1, and communication equipment 1 time Between still be able to listen to this M competition communication equipment at least one listening period at the end of window and persistently account for With Radio Resource 1, then the priority of this M competition communication equipment is higher than communication equipment 1.The embodiment of the present invention As a example by competition communication equipment is for communication equipment 2, certainly, communication equipment 1 may also confirm that out other competition Communication equipment, the embodiment of the present invention does not limits.

Optionally, communication equipment 1 can persistently be monitored in time window, or according in advance in time window If monitoring frequency to monitor.Optionally, the time window of communication equipment 1 can include at least one listening period, The i.e. minimum time unit of time window is a listening period, as long as communication equipment 1 ensures to monitor week each Monitor a time point in phase or a time period can realize above-mentioned listening mode.

If it should be noted that listening to Radio Resource in the time window 1 that communication equipment 1 is in communication equipment 1 1 is persistently taken by competition communication equipment, then communication equipment 1 also will be to wireless money at least one listening period Source 1 is monitored, then communication equipment 2 is for guaranteeing competition to Radio Resource 1, in communication equipment 2 time Between the window length of window 2 need to meet window length and at least one listening period sum more than or equal to time window 1.

Step S404, if communication equipment 1 judge can successful contention to Radio Resource 1, then communication equipment 1 exists Time window sends data based on Radio Resource 1 after terminating.

In one embodiment, if communication equipment 1 judges to compete Radio Resource 1, then show to lead to The priority of letter equipment 1 is high compared with the priority of communication equipment 2, then communication equipment 1 can send data.

Optionally, communication equipment 1 can send data by Radio Resource 1, it is possible to by above-mentioned with wireless Resource 1 becomes the Radio Resource 2 of mapping relations to send data.Shown in Figure 10, may specify that wireless money Source 1 and the mapping relations of Radio Resource 2.Wherein, the vertical direction in Figure 10 represents frequency domain, in Figure 10 Horizontal direction represents time domain.A kind of situation is that Radio Resource 1 can be the son of Radio Resource 2 on frequency domain Resource (Radio Resource 11～Radio Resource 1N), such as Radio Resource 2 is one or more physics on frequency domain Resource Block (Radio Resource 21～Radio Resource 2N), comprises 12 × P subcarrier, and wherein P is positive integer, And Radio Resource 1 part for subcarrier occupied by Radio Resource 2, concrete mapping relations on frequency domain Can be found in Figure 10 a.Another kind of situation is to there is continuous distribution on frequency domain and multiple Radio Resource 1 (nothing Line resource 11～Radio Resource 1N) it is used for sending detection information, on frequency domain, continuous distribution multiple wireless money Source 2 (Radio Resource 21～Radio Resource 2N) is used for sending data, and these Radio Resources 1 are each corresponding One Radio Resource 2, concrete mapping relations can be found in Figure 10 b.

Optionally, the detection information that communication equipment 1 sends can be a part for data to be sent, communication equipment When judging to compete Radio Resource 1 or Radio Resource 2, can continue to send data to be sent.Specifically , if communication equipment 1 detects that the time window window length in self is for the window long maximum or higher of time window During value, communication equipment 1 can send the part in data to be sent, when communication equipment 1 competition is to wireless money Behind source 1 or Radio Resource 2, can continue to send remainder, thus communication equipment 1 can make full use of wireless Resource, while avoiding resource contention, further increases transmitting efficiency.

Step S405, if communication equipment 1 judge can not successful contention to Radio Resource 1, then communication equipment 1 Stop competition Radio Resource 1.

In one embodiment, if communication equipment 1 judge can not successful contention to Radio Resource 1, then Communication equipment can stop competing Radio Resource 1.Concrete, if communication equipment 1 listens to nothing in time window Line resource 1 is persistently taken, and also listens to nothing at least one listening period at the end of time window Line resource 1 is persistently taken, then communication equipment 1 can stop competing nothing at the end of at least one listening period Line resource 1；If or communication equipment 1 can interpolate that out communication equipment 2 excellent of competition Radio Resource 1 simultaneously First level is high, then communication equipment 1 can judge that communication equipment 2 priority stops competing higher than the moment of this equipment Strive Radio Resource 1.

Optionally, communication equipment 1, after notice competition Radio Resource 1, can continue in detection wireless resource pool Other Radio Resources the most idle.Concrete, other Radio Resources of detection can be joined by network equipment Determining in the set of radio resources that put or communication equipment 1 is pre-configured with self, communication equipment can be wireless at this From one Radio Resource detection of main separation in resource collection, it is possible to determine the wireless of detection according to default sequence Resource.

Unappropriated first Radio Resource during communication equipment determines Radio Resource pond in the embodiment of the present invention After, communication equipment sends detection information by this first Radio Resource in time window, wherein, different The time window sending detection information in communication equipment may be different, and communication equipment is by sending detection information Time listen to exist competition communication equipment compete the first Radio Resource simultaneously, then communication equipment determines whether This communication equipment whether can successful contention to the first Radio Resource, if this communication equipment is judged to become Merit competes the first Radio Resource, then become to map by this first Radio Resource or with this first Radio Resource Second Radio Resource of relation sends data, if this communication equipment judge can not successful contention to this One Radio Resource, then stop the competition to this first Radio Resource.Thus, when multiple communication equipments while During one Radio Resource of competition, avoid resource contention conflict by the way.And communication equipment 1 exists When not competing a Radio Resource in Radio Resource pond, can compete or its in detection wireless resource pool His resource, adds communication equipment 1 and sends the motility of information, and be effectively increased transmission information efficiency.

In conjunction with shown in Fig. 4 embodiment describe communication equipment 1 or the execution step of communication equipment 2, below right In Fig. 3, communication equipment 1 is specifically described with the competition process of communication equipment 2.As it is shown on figure 3, communication sets Standby 1 is configured with communication equipment 2 or determines Radio Resource 1 from main separation, it should be noted that when communication sets When being configured for, for 1 or communication equipment 2, the order situation determining Radio Resource in Radio Resource pond, in communication When equipment 1 or communication equipment 2 determine Radio Resource first, it is not necessary to before this Radio Resource is monitored, When communication equipment 1 or communication equipment 2 need from main separation Radio Resource, then can before determining Radio Resource, As shown in Fig. 3 monitoring stage in fact, determine that this Radio Resource is the most idle by monitoring this Radio Resource.? The t1 moment sends detection information by Radio Resource 1 simultaneously, and wherein, user 1 sends detection information 1, and user 2 Send detection information 2.As it is shown on figure 3, the window of the time window of communication equipment 1 a length of t1～t2 time period；Communication Window a length of t1～t3 time period of the time window of equipment 2.Wherein, the window length of the time window of communication equipment 2 is more than The window of the time window of communication equipment 1 is long.

If detection information 1 and detection information 2 are detection sequence, communication equipment 1 started in the t1 moment can Listen to Radio Resource 1 taken by communication equipment 2 simultaneously, thus detection information 2 can be parsed, and by resolving The detection information 2 gone out learns that communication equipment 2 can also contrast detection information 2 at competitive resource, communication equipment 1 The precedence information carried and the precedence information in detection information 1, as it is shown on figure 3, communication equipment 1 contrasts When going out the priority of communication equipment 2 higher than communication equipment 1, can stop competing Radio Resource 1, therefore can be at t2 The competition of Radio Resource 1 was exited before moment.In like manner, communication equipment 2 also can judge this by the way The priority of end is high, can hold over Radio Resource 1.

If detection information 1 and detection information 2 are detection data, or during random probing sequence, i.e. communication sets The standby priority that cannot be judged rival by the detection information got, now, communication equipment 1 is with logical Letter equipment 2 can continue monitoring wireless resource 1 in respective time window respectively, and communication equipment 1 is in time window (t1～t2) persistently listens to Radio Resource 1 and hurries, then at the end of t2 moment, i.e. time window, and communication equipment 1 Also will be at least one listening period T_dWhether interior continuation monitoring wireless resource 1 is taken by communication equipment 2, if Communication equipment 1 is persistently monitored at least one listening period and is given to Radio Resource 1 and is still accounted for by communication equipment 2 With, then communication equipment 1 stops competition Radio Resource 1.Certainly, communication equipment 1 can also continue to detection wireless money Other Radio Resources in pond, source are the most idle, with other Radio Resources of competitive utilization.Communication equipment 2 time Between window (t1～t3) continue monitoring wireless resource 1, communication equipment 2 listens to wireless money within t2～the t3 time period Source 1 is idle, then communication equipment 2 is at the end of t3 moment i.e. time window, can hold over Radio Resource 1 and transmit Data.Aforesaid way effectively avoids resource contention.

Certainly, communication equipment 1 sends detection information 1 and communication equipment 2, and to send detection information separate, logical The detection information 1 that letter equipment 1 sends can be detection sequence, and the detection information 2 that communication equipment 2 sends can be to visit Survey data, here, the embodiment of the present invention does not limits.

For the competitive way described by the embodiment shown in Fig. 4, there is also a kind of possible situation is that communication sets Identical with the time window window length of communication equipment 2 for 1, i.e. communication equipment 1 and communication equipment 2 are based on this time window Priority identical, then communication equipment 1 and communication equipment 2 also need to again be at war with Radio Resource 1, Relative to the first round competitive way described in the embodiment shown in Fig. 4, the embodiment shown in Fig. 5 will describe Communication equipment 1 takes turns competitive way with the second of communication equipment 2, in the first round competes communication equipment 1 with communicate The time window of equipment 2 is identical, then can be found in the competition flow chart shown in Fig. 5, further determine that concrete which Communication equipment can compete Radio Resource 1.Certainly, can set with communication in conjunction with the communication equipment 1 shown in Fig. 6 The competition process of standby 2.

Concrete, referring to Fig. 5, Fig. 5 is another kind of resource competition method disclosed in the embodiment of the present invention Schematic flow sheet.Method shown in Fig. 5 can be applicable to communication equipment 1 or communication equipment 2, the embodiment of the present invention with Illustrating as a example by communication equipment 1, the method can comprise the following steps.

Step S501, if communication equipment 1 judges that communication equipment 1 is identical with the priority of communication equipment 2, then Communication equipment 1 judges whether to compete Radio Resource 1 again.

In one embodiment, communication equipment 1 judges communication by step S504 in embodiment illustrated in fig. 4 Equipment 1 is the most identical with the priority of communication equipment 2.Concrete, such as the description in step S504, communication Whether equipment 1 can be by the precedence information entrained by the detection information 2 of contrast communication equipment 2 transmission with logical The precedence information that the detection information 1 that letter equipment 1 sends carries is identical, if identical, then shows communication equipment 1 Identical with the priority of communication equipment 2；Or, communication equipment 1 listens in the time window of communication equipment 1 Communication equipment 2 the most persistently takies Radio Resource 1, and communication equipment 1 at the end of time window at least one Listening to Radio Resource 1 in individual listening period idle, communication equipment 2 takies Radio Resource 1 the most again, then shows Time window in communication equipment 1 is identical with the window length of the time window in communication equipment 2, then further demonstrate that logical Letter equipment 1 is identical with the priority of communication equipment 2, and certainly, communication equipment 1 determines whether and communication equipment 2 Priority identical may also include other modes, wouldn't repeat at this.

When communication equipment 1 is identical with the priority of communication equipment 2, then communication equipment 1 needs with communication equipment 2 Carry out second and take turns competitive channel.Owing to communication equipment 1 is identical with the window length of the time window of communication equipment 2 or The priority that person is configured is identical, then communication equipment 1 and communication equipment 2 need new pre-defined rule the most true Its priority fixed, can distinguish communication equipment 1 and communication equipment 2.

Wherein, new pre-defined rule can be to participate in the second communication equipment taking turns competition to be allocated one with aircraft window Long time window, wherein, each the most different with aircraft window length, and the starting point of each time window is the most identical, Then ensure that participating in the second communication equipment taking turns resource contention can distinguish priority, and ensure that logical Letter equipment competes Radio Resource 1 simultaneously, when communication equipment sends detection information in the time window of different window length Time, determine that the mode of communication equipment priority can be found in the mode described in above-mentioned steps S504, certainly described Detection information can be identical or different from the detection information of first round competition, it is possible to for controlling information or number According to waiting other information.Or, new pre-defined rule can be to participate in the second communication equipment taking turns competition to select at random Select a random chance in predetermined probabilities set, and based on this random chance in Radio Resource 1 or phase therewith Detection information (or the information of control and and its corresponding data) is sent on corresponding Radio Resource 2. Owing to each communication equipment has randomly choosed a probability, then at synchronization, different communication equipment bases Can send detection information in probability, probability is the highest, then the probability sending detection information is the biggest, and probability is more Low, then the probability sending detection information is the least；At synchronization, it is believed that detection information can be sent The priority of communication equipment is high.Certainly, due to general with randomly choose with aircraft window length in above two mode All there is certain randomness in rate, it is possible to different communication equipments occurs with aircraft window length or random chance phase Same situation, in this case it is desirable to carry out the competition of third round competition or more wheels further, the 3rd The pre-defined rule that the pre-defined rule of the competition of wheel competition or more wheels can take turns competition with second is identical, until choosing Go out the communication equipment that can compete Radio Resource 1.

Certainly, if communication equipment needs to participate in second takes turns competition, new pre-defined rule can include aforesaid way In one or more, and predeterminable decision condition determines that communication equipment selects in new pre-defined rule Kind carries out second and takes turns competition.The decision condition preset can be whether communication equipment possesses default Making by Probability Sets, Or whether communication equipment can be probabilistically assigned a new time window etc., optionally, being taken in time domain can When time for sending detection information is less than time window, randomly choose a transmission information, in time domain When the fooled time that can be used for transmission detection information is more than or equal to time window, select to send detection information, The embodiment of the present invention does not limits.

Step S502, if communication equipment 1 judge can successful contention to Radio Resource 1, then communication equipment 1 exists Time window sends data based on Radio Resource 1 after terminating.

Step S503, if communication equipment 1 judge can not successful contention to Radio Resource 1, then communication equipment 1 Stop competition Radio Resource 1.

In one embodiment, step S502 can see Fig. 4 institute respectively with the concrete executive mode of step S503 Show step S405 and the embodiment of S406 in embodiment.

In the embodiment of the present invention, when same Radio Resource competed by multiple communication equipments, if multiple communication equipment Identical at first round resource contention medium priority, then multiple communication equipments can be introduced second and take turns resource contention Or more wheels, until a communication equipment can be had to compete this resource, and then avoid money more accurately Conflict in source.

In conjunction with Fig. 4 and Fig. 5, referring to Fig. 6, Fig. 6 below is another kind of manifold disclosed in the embodiment of the present invention The process schematic of letter equipment competitive resource.Fig. 6 to the first round competition of communication equipment 1 and communication equipment 2 with Second takes turns competition is described in detail.

As shown in Figure 6, communication equipment 1 is identical with the window length of the time window in communication equipment 2, then communication equipment The time period of 1 transmission detection information 1 is at t1～t2, and communication equipment 2 sends the time period of detection information 2 also At t1～t2, if communication equipment 1 and communication equipment 2 are preferential by resolve mutually that the detection information sent carries Level information determines that the two priority is identical, or communication equipment 1 is supervised within t1～the t2 time period with communication equipment 2 Hear that Radio Resource 1 is persistently taken, and at least one listening period T at the end of time window_dInterior prison Hear that Radio Resource 1 is idle, then with communication equipment 2, communication equipment 1 can determine that the two priority is identical, then need Prepare second and take turns the competition to Radio Resource 1.As shown in Figure 6, with communication equipment 1 and communication equipment 2 quilt As a example by the time window that new one window length of distribution is random, then communication equipment 1 can be by further with communication equipment 2 In new time window monitoring wireless resource 1, it is determined whether competition to Radio Resource 1.Communication equipment 1 with communicate Equipment 2 sends detection information again in the t3 moment, and wherein, the window of the allocated time window of communication equipment 1 is a length of T3～t4, the window length of the allocated time window of communication equipment 2 is t3～t5, when the time window of communication equipment 1 is tied Shu Shi, communication equipment 2 still sends detection information taking Radio Resource 1, then communication equipment 2 is taken turns competing second Strive middle competition and compete Radio Resource 1, optionally, communication equipment 1 to Radio Resource 1, communication equipment 1 stopping Other Radio Resources in detection wireless resource pool can be continued.
