In order to preferably support the dynamic change of business load, 5G newly eats dishes without rice or wine to have studied dynamic Time Division duplex in technology (Time Division Duplexing, TDD) technology is supported flexibly to change downstream transmission direction in TDD frequency spectrum.But It is, compared with traditional LTE system, when neighboring transmission point (Transport Point, TRP) transmission direction is inconsistent, dynamic TDD technology may introduce new interference type, wherein new interference type includes interference and the user terminal between TRP and TRP Interference between (User Equipment, UE) and UE.For example, as shown in Figure 1, showing for the interference problem under dynamic TDD scene It is intended to.In Fig. 1, in slot n, TRP1 is downlink transfer, and UE1 is serviced by TRP1, and TRP2 is uplink, and UE2 quilt TRP2 service.During downstream transmission, on the one hand, TRP2 is when listening to the uplink signal of UE2 transmission, it is also possible to listen to The downlink signal (i.e. interference between TRP and TRP) that TRP1 is sent, therefore the downlink signal that TRP1 is sent may interfere with TRP2 The uplink signal of side is listened to, such interference is referred to as the interference between TRP and TRP, and can be referred to interference of the downlink to uplink. On the other hand, UE1 is when listening to the downlink signal of TRP1 transmission, it is also possible to listen to uplink signal (i.e. UE and the UE of UE2 transmission Between interference), therefore the uplink signal that sends of UE2 may interfere with the downlink signal of the side UE1 and listen to, such interference is referred to as Interference between UE and UE, and can be referred to interference of the uplink to downlink.

In conclusion the difference of the transmission direction of adjacent area will lead to the generation of new interference type, and new interference type Generation various harm can be caused to communication system.On the one hand, new interference source causes to listen to end signal and interfere plus make an uproar Acoustic ratio (Signal to Interference plus Noise Ratio, SINR) decline, and then deteriorate demodulation performance；It is another Aspect, new interference source are also possible to frequently result in that down channel measurement result is out-of-date or failure, and then deteriorate Adaptive Modulation and compile The working performance of ink recorder system (Adaptive Modulation and Coding, AMC).For example, as shown in Fig. 2, believing for downlink The descending transmission channel mismatch schematic diagram of road measurement result and actual use.In FIG. 2, it is assumed that base station is based on UE in slot n- The down channel quality measurement result reported in k1 determines descending scheduling resource and Corticofugal Modulation of Somatosensory coding strategy in slot n (Modulation and Coding Scheme, MCS) parameter, wherein UE is reported in slot n-k1 in slot n-k1-k2 In measure downlink channel condition information (Channel State Information, CSI) measurement quality measurements.? In Fig. 2, downstream transmission of the peripheral base station (including TRP2, TRP3 and TRP4) of base station in slot n-k1-k2 and slot n Direction is not quite similar, therefore down channel quality of the UE measured by slotn-k1-k2 and base station are experienced in the slot n Down channel quality is made great difference, and so as to cause in dynamic TDD scene, the down channel quality measurement result of UE feedback is frequent Be it is out-of-date with it is invalid, and then deteriorate AMC mechanism working performance.

In the present invention in order to solve in the prior art due to that can not identify adjacent area downstream transmission direction, so as to cause The problem of out-of-date new interference type and down channel quality measurement result or failure are easy to produce in dynamic TDD scene, this Inventive embodiments provide the communication means between a kind of base station, which is applied to first base station, specifically, the communication party Method includes:

In the transmission time unit for carrying out the transmission of upstream or downstream data, first base station sends the in first time window The exclusive signal of eating dishes without rice or wine of one base station itself, and listen to the first of the transmission of the second base station in the second time window and eat dishes without rice or wine signal；Wherein, First signal of eating dishes without rice or wine includes the second exclusive signal of eating dishes without rice or wine for eating dishes without rice or wine signal and second base station itself that the second base station listens to.

Specifically, first base station and the second base station are the base station for not supporting full duplex, and first base station refers to the first kind Base station, the second base station refers to the base station of Second Type, and the second base station is the peripheral base station of first base station.As long as in this way, being the The base station of one type sends the exclusive signal of eating dishes without rice or wine of first base station itself in first time window, and detects in the second time window Listen that the base station of Second Type sends first is eated dishes without rice or wine signal.Correspondingly, the second base station is in the transmission time unit, at first Between window listen to first base station transmission first base station itself exclusive signal of eating dishes without rice or wine, and it is empty in the second time window to send first Message number.Specifically, first signal of eating dishes without rice or wine includes second eating dishes without rice or wine signal and second base station of listening to of the second base station itself Exclusive signal of eating dishes without rice or wine.In addition, the second base station listen to second eat dishes without rice or wine that include first base station send signal in first time window First base station itself exclusive signal of eating dishes without rice or wine.

In this way, first base station is by sending the exclusive signal of eating dishes without rice or wine of first base station itself in first time window, and the What two time windows listened to the transmission of the second base station first eats dishes without rice or wine signal, this includes that the second base station listens in the first signal of eating dishes without rice or wine Second eat dishes without rice or wine signal when so that the second base station, which for first base station, can play, repeats the second base station listens to the Two effects for eating dishes without rice or wine signal.This second eats dishes without rice or wine to belong in the peripheral base station that signal includes first base station what the second base station listened to The base station of the first kind it is exclusive eat dishes without rice or wine signal when, first base station can be got in period base station in the second time window to be belonged to The exclusive signal of eating dishes without rice or wine of the base station of the first kind；In addition, first base station can also get the second base station for belonging to Second Type The exclusive signal of eating dishes without rice or wine of itself, this enables first base station to get the exclusive signal of eating dishes without rice or wine of peripheral base station simultaneously, and then makes Obtaining first base station can be according to the exclusive signal acquisition of eating dishes without rice or wine of peripheral base station to the downstream transmission direction of peripheral base station, and then solves It has determined in the prior art due to that can not identify adjacent area downstream transmission direction, has been easy to produce so as to cause in dynamic TDD scene The problem of new interference type and down channel quality measurement result is out-of-date or fails.

Further, in the transmission time unit for carrying out the transmission of upstream or downstream data, first base station is in the third time Window sends third and eats dishes without rice or wine signal, and wherein third signal of eating dishes without rice or wine is eated dishes without rice or wine signal including at least first.Correspondingly, the second base station is Three time windows receive the third and eat dishes without rice or wine signal.

In this way due to first eat dishes without rice or wine signal include second base station itself exclusive signal of eating dishes without rice or wine, this eats dishes without rice or wine signal packet in third Include first eat dishes without rice or wine signal when so that first base station for the second base station, can equally play repeat the second base station itself Exclusive signal of eating dishes without rice or wine effect.This enables the second base station to get the exclusive skies of other base stations for being similarly Second Type Message number so that first base station and the second base station can get the exclusive signal of eating dishes without rice or wine of peripheral base station, and makes One base station and the second base station can be according to the exclusive signal acquisitions of eating dishes without rice or wine of peripheral base station to the downstream transmission side of peripheral base station To.

Specifically, first time window, the second time window and third time window can in a transmission time unit In slot time in a time slot.It is specific as shown in figure 3, in Fig. 3, first time window, the second time window and Third time window is in a slot time of slot n.

In addition, specifically, in a transmission time unit, first time window, the second time window and third time Window also may be in the slot time of different time-gap.Specifically as shown in figure 4, first time window is in slot in Fig. 4 In the starting time slots interval of n, and the second time window and third time window are in the ending slot time of slot n-1.Separately It is outer specifically, can also first time window and the second time window be in the starting time slots interval of slot n, and when third Between window be in the ending slot time of slot n-1.

Certainly it should be noted that referring to Fig. 3 and Fig. 4, when first time window, the second time window and third Between window when being in the slot time of different time-gap, the time interval between first time window and the second time window is compared with One time window, the second time window and third time window are in for the slot time of same time slot, and spacing is larger, in this way More processing times can be reserved to base station.

In addition, further, in order to guarantee that adjacent base station can get the signal of eating dishes without rice or wine of other side each other, then every one first It is needed around base station there are the second base station, otherwise first base station will be unable to obtain adjacent base station information.

This scene is described in detail below.

Assuming that include at one base station A, base station B, tetra- base stations base station C and base station D cell site topology relationship in, base station A is merely able to listen to the signal of base station B and base station C, and base station B can listen to the signal of base station A, base station C and base station D, base station C The signal of base station A, base station B and base station D can be listened to, base station D is merely able to listen to the signal of base station B and base station C.

At this time, it is assumed that in first transmission time unit, base station A, base station B, base station C and base station D are first base station, That is base station A, base station B, base station C and base station D select to send the exclusive signal of eating dishes without rice or wine of itself in first time window, at second Between window listen to the first of the transmission of the second base station and eat dishes without rice or wine signal.In this way due at this time in the second time window, base station A, base station B, base station C and base station D is in without base station all in state is listened to and sends eat dishes without rice or wine signal condition, therefore base station A, base at this time Any one of B, base station C and tetra- first base stations of base station D first base station of standing cannot all listen to the sky of other base stations transmission Message number.

For above-mentioned scene, first base station and the second base station in cell site topology relationship can be configured by following manner.

First, can be configured by Operations, Administration and Maintenance (OAM), configure first base station in cell site topology relationship and Second base station.Such as can configure base station B and base station C is first base station, base station A and base station D are the second base station, in this way first Base station sends the exclusive signal of eating dishes without rice or wine of first base station itself in first time window, listens to the second base station in the second time window and sends out First sent is eated dishes without rice or wine signal, and the exclusive of the first base station of first base station transmission itself is listened in first time window in the second base station Eat dishes without rice or wine signal, the second time window send first eat dishes without rice or wine signal when, base station B and base station C can be guaranteed in the second time window It listens to base station A and base station D are sent first to eat dishes without rice or wine signal, and can guarantee that base station A and base station D can be in first time window Listen to the exclusive signal of eating dishes without rice or wine that exclusive eat dishes without rice or wine signal and the base station C of base station B transmission are sent.

Second, by wired or wireless back haul link interface between base station, cell site topology relationship can be coordinated in initialization In base station as first base station or the second base station, to guarantee that there are the second base stations around first base station.

Third, can also monitor in the second time window of the first Preset Transfer time quantum, if can listen to First eats dishes without rice or wine signal；When can listen to first eat dishes without rice or wine signal when, according to predetermined period, periodically change the work of first base station Mode；When can not listen to first eat dishes without rice or wine signal when, the random operating mode for changing first base station, and when monitoring second Can be listened in Preset Transfer time quantum first eat dishes without rice or wine signal when, according to predetermined period, periodically change first base station Operating mode；Wherein, predetermined period includes at least one transmission time unit, and the second Preset Transfer time quantum is greater than first Preset Transfer time quantum；Operating mode includes: to send the exclusive signal of eating dishes without rice or wine of first base station itself in first time window, What the second time window listened to the transmission of the second base station first eats dishes without rice or wine signal, and sends third in third time window and eat dishes without rice or wine signal First operating mode；And listen to the 4th of the transmission of the second base station in first time window and eat dishes without rice or wine signal, in the second time window It sends the 5th to eat dishes without rice or wine signal, and listens to the 6th of the transmission of the second base station the second Working mould for eating dishes without rice or wine signal in third time window Formula；Wherein, the 5th signal of eating dishes without rice or wine includes the 4th exclusive signal of eating dishes without rice or wine for eating dishes without rice or wine signal and first base station itself.

Specifically, when first base station monitor the second time window can listen to first eat dishes without rice or wine signal when, illustrate There are the second base stations around one base station, only need to periodically change the operating mode of first base station according to predetermined period at this time. Certainly, predetermined period can be at least one Preset Transfer time quantum.Correspondingly, at this time the second base station in first time window The exclusive signal of eating dishes without rice or wine of the first base station of first base station transmission itself can be listened to, then the second base station also only need to be according to identical Predetermined period periodically changes the operating mode of the second base station.

This scene is illustrated below.

For example, it is assumed that predetermined period is a Preset Transfer time quantum, base station B and base station C are first base station, base station A It is the second base station with base station D, and operating mode of the base station B and base station C in the first Preset Transfer time quantum is the first work The operating mode of mode, base station A and base station D in the first Preset Transfer time quantum is third operating mode, i.e., pre- first If in transmission time unit, base station B and base station C are in the exclusive signal of eating dishes without rice or wine of first time window transmission base station itself, base station A The base station that exclusive eat dishes without rice or wine signal and the base station C of the base station of base station B transmission itself are sent is listened in first time window with base station D The exclusive signal of eating dishes without rice or wine of itself, base station A and base station D send first in the second time window and eat dishes without rice or wine signal, base station B and base station C The second time window listen to the first of base station A transmission eat dishes without rice or wine that signal and base station D send first eat dishes without rice or wine signal, base station B and Base station C sends third in third time window and eats dishes without rice or wine signal, and base station A and base station D receive base station B hair in third time window The third the sent third that signal and base station C are sent of eating dishes without rice or wine is eated dishes without rice or wine signal.At this point, the operating mode of periodically change first base station, And periodically change the operating mode of the second base station, i.e., in the second Preset Transfer time quantum, by the Working mould of first base station Formula is changed to the second operating mode by the first operating mode, and the operating mode of the second base station is changed to by third operating mode Four operating modes.I.e. in the second Preset Transfer time quantum, base station A and base station D send base station sheet in first time window The exclusive signal of eating dishes without rice or wine of body, base station B and base station C the 4th eat dishes without rice or wine signal and base what first time window listened to base station A transmission What the D that stands was sent the 4th eats dishes without rice or wine signal, and base station B and base station C send the 5th in the second time window and eat dishes without rice or wine signal, base station A and base Stand D the second time window listen to the 5th of base station B transmission eat dishes without rice or wine that signal and base station C send the 5th eat dishes without rice or wine signal, and base The A and base station D that stands sends the 6th eat dishes without rice or wine signal, base station B and base station C in third time window and in third time window listens to base The A that stands send the 6th eat dishes without rice or wine that signal and base station D send the 6th eat dishes without rice or wine signal.

Wherein due to first eat dishes without rice or wine signal include the second base station (base station A and base station D) listen to second eat dishes without rice or wine signal and The exclusive signal of eating dishes without rice or wine of base station itself, so that the second base station (base station A and base station D) is relative to first base station (base station B and base Stand C) for, it can play the role of repeating signal of eating dishes without rice or wine, base station B is enabled to obtain base station A, base station in the second time window The exclusive signal of eating dishes without rice or wine of the base station of C and base station D itself, and base station C is enabled to obtain base station A, base station B in the second time window With the exclusive signal of eating dishes without rice or wine of the base station of base station D itself.Further, since third is eated dishes without rice or wine, signal includes at least first and eats dishes without rice or wine signal, and First signal of eating dishes without rice or wine includes the second exclusive sky for eating dishes without rice or wine signal and base station itself that the second base station (base station A and base station D) is listened to Message number so that base station A can get the exclusive signal of eating dishes without rice or wine of base station of base station B, base station C and base station D itself, and makes The exclusive signal of eating dishes without rice or wine of base station itself of base station A, base station B and base station C can be got by obtaining base station D, i.e., so that first base station (base Stand B and base station C) for the second base station (base station A and base station D), it can equally play the role of repeating signal of eating dishes without rice or wine.

In addition, specifically, when first base station can not listen to first eat dishes without rice or wine signal when, illustrate not deposit around first base station In the second base station, the operating mode of first base station can be changed at random at this time, i.e. first base station can be changed with a predetermined probabilities The operating mode of first base station.For example, it is assumed that predetermined period is a Preset Transfer time quantum, and first base station is pre- first If the operating mode in transmission time unit is the first operating mode, then first base station is in the second Preset Transfer time quantum Operating mode can be changed to the second operating mode with a predetermined probabilities, i.e., first base station is in the second Preset Transfer time quantum Operating mode may be the second operating mode, it is also possible to be maintained the first operating mode.At this point, due to the work of first base station Mode is random change, then it cannot be guaranteed that there are first base stations in the second Preset Transfer time quantum by the change of the first operating mode More the second operating mode then needs to continue at this time to change the operating mode of first base station at random, until in the second Preset Transfer Can be listened in time quantum first eat dishes without rice or wine signal when until, that is, there is first base station in the second Preset Transfer time quantum Until when being changed to the second operating mode by the first operating mode, it can then proceed in predetermined period, periodically change the first base The operating mode stood correspondingly periodically changes the operating mode of the second base station.

This scene is illustrated below.

For example, it is assumed that predetermined period is a Preset Transfer time quantum, and base station A, base station B, base station C and base station D are equal For first base station, and the operating mode of base station A, base station B, base station C and base station D in the first Preset Transfer time quantum is One operating mode.Base station A in this way, base station B, base station C and base station D can not listen to first and eat dishes without rice or wine signal, at this time can be with Machine changes the operating mode of base station A, base station B, base station C and base station D, until there are bases in base station A, base station B, base station C and base station D Until the operating mode stood is changed to the second operating mode by the first operating mode, predetermined period can then proceed in, periodically The operating mode of first base station is changed, correspondingly, periodically changes the operating mode of the second base station.

In this way monitor can to listen in the second Preset Transfer time quantum first eat dishes without rice or wine signal when, according to default Period periodically changes the operating mode of first base station, the operating mode of first base station is occurred according to predetermined period Change, so that first base station for the second base station, can equally play the role of repetition, so that the second base The exclusive signal of eating dishes without rice or wine of period base station can also be got by standing, so that the second base station can be according to the exclusive sky of peripheral base station Message number gets the downstream transmission direction of peripheral base station.

In addition, further, as shown in figure 5, for the detailed step flow chart of the communication means applied to first base station.It should Communication means further includes following steps:

Step 501, in the transmission time unit for carrying out the transmission of upstream or downstream data, the is sent in first time window The exclusive signal of eating dishes without rice or wine of one base station itself, and listen to the first of the transmission of the second base station in the second time window and eat dishes without rice or wine signal.

Step 502, it according to the default corresponding relationship between Base Station Identification and the frequency domain resource of the exclusive signal of eating dishes without rice or wine of transmission, obtains The exclusive frequency domain of corresponding with the Base Station Identification of the second base station exclusive signal of eating dishes without rice or wine for sending second base station itself is taken to provide Source.

Specifically, can pre-establish Base Station Identification and base station send exclusive signal of eating dishes without rice or wine exclusive frequency domain resource it is default Corresponding relationship, the default of exclusive frequency domain resource for sending exclusive signal of eating dishes without rice or wine by establishing Base Station Identification and base station so corresponding are closed System, then can get the exclusive frequency domain resource that the corresponding base station of Base Station Identification sends exclusive signal of eating dishes without rice or wine according to Base Station Identification.

Specifically, base station frequency domain resource used in different transmission time units may be identical, it is also possible to different. It, can be according to preset hopping pattern not when base station frequency domain resource difference used in different transmission time units The frequency domain position of base station itself is selected in same transmission time unit.

Step 503, according to the sequence type sent in exclusive frequency domain resource and exclusive frequency domain resource, the second base station is obtained Transmitted information.

Specifically, information transmitted by the second base station includes transmission direction of second base station in current time slots.

Wherein, due to all base stations it is exclusive eat dishes without rice or wine signal can from some predefined arrangement set value, and Information is carried by sequence type.Such as two kinds of sequence types are included at least in arrangement set, wherein sequence 0 indicates working as base station Preceding time slot is that main time slot is transmitted as with downlink, and sequence 1 indicates that the current time slots of base station are that main time slot is transmitted as with uplink.? This can be according to the sequence type sent in exclusive frequency domain resource and exclusive frequency domain resource, and synthesis is being worked as to obtain the second base station The transmission direction of preceding time slot.At this point, when exclusive frequency domain resource is the sequence sent in the first frequency domain resource and the first frequency domain resource When type is First ray type, the second base station is uplink direction in the transmission direction of current time slots；When exclusive frequency domain provides Source is the sequence type sent in the second frequency domain resource and the second frequency domain resource when being the second sequence type, and the second base station is current The transmission direction of time slot is downlink transmission direction；When exclusive frequency domain resource is to send in third frequency domain resource and third frequency domain resource Sequence type be third sequence type when, the second base station current time slots be idle state.

Step 504, the transmission direction according to the second base station in current time slots, the determining present channel phase with first base station The down channel quality measurement result matched.

In this step, specifically, first can be made when getting transmission direction of second base station in current time slots Base station can select the down channel quality measurement result to match with the present channel of first base station, to avoid down channel The problem of quality measurements are out-of-date or fail.

In this way, the first base station in the embodiment of the present invention is by sending the exclusive of first base station itself in first time window It eats dishes without rice or wine signal, and listens to the first of the transmission of the second base station in the second time window and eat dishes without rice or wine signal, this includes in the first signal of eating dishes without rice or wine Second base station listen to second eat dishes without rice or wine signal when so that the second base station for first base station, can play repetition The second effect for eating dishes without rice or wine signal that two base stations listen to, to include the first base in the second signal of eating dishes without rice or wine that the second base station listens to The peripheral base station stood send it is exclusive eat dishes without rice or wine signal when, first base station can get the special of peripheral base station in the second time window The exclusive signal of eating dishes without rice or wine for belonging to eat dishes without rice or wine signal and second base station itself, so that first base station can be according to the exclusive of peripheral base station Signal acquisition eat dishes without rice or wine to the downstream transmission direction of peripheral base station, and then solves in the prior art due to that can not identify on adjacent area Downlink transmission direction, so as to cause new interference type and down channel quality measurement is easy to produce in dynamic TDD scene As a result the problem of out-of-date or failure.

On the other hand, the embodiment of the invention also provides a kind of communication means applied to the second base station, the communication means It include: to listen to first base station in the transmission time unit for carrying out the transmission of upstream or downstream data in first time window and send First base station itself exclusive signal of eating dishes without rice or wine, and send first in the second time window and eat dishes without rice or wine signal；Wherein, it first eats dishes without rice or wine letter It number include the second exclusive signal of eating dishes without rice or wine for eating dishes without rice or wine signal and second base station itself that the second base station listens to.Specifically, second is empty Message number includes the exclusive signal of eating dishes without rice or wine for the first base station that the second base station is listened in first time time window itself.

Specifically, first base station and the second base station are the base station for not supporting full duplex, and first base station refers to the first kind Base station, the second base station refers to the base station of Second Type, and first base station is the peripheral base station of the second base station.As long as in this way, being the The base station of two types first time window listen to first base station transmission first base station itself exclusive signal of eating dishes without rice or wine, and Second time window sends first and eats dishes without rice or wine signal.Correspondingly, first base station is in the transmission time unit, in first time window Send the exclusive signal of eating dishes without rice or wine of first base station itself, and the first sky sent in the base station that the second time window listens to Second Type Message number.

In this way, the second base station by first time window listen to first base station transmission first base station itself exclusive sky Message number, and send first in the second time window and eat dishes without rice or wine signal, this includes that the second base station listens in the first signal of eating dishes without rice or wine Second eat dishes without rice or wine signal when so that the second base station, which for first base station, can play, repeats the second base station listens to the Two effects for eating dishes without rice or wine signal.This second eats dishes without rice or wine to belong in the peripheral base station that signal includes first base station what the second base station listened to The base station of the first kind it is exclusive eat dishes without rice or wine signal when, first base station can be got in period base station in the second time window to be belonged to The exclusive signal of eating dishes without rice or wine of the base station of the first kind；In addition, first base station can also get the second base station for belonging to Second Type The exclusive signal of eating dishes without rice or wine of itself, this enables first base station to get the exclusive signal of eating dishes without rice or wine of peripheral base station simultaneously, and then makes Obtaining first base station can be according to the exclusive signal acquisition of eating dishes without rice or wine of peripheral base station to the downstream transmission direction of peripheral base station, and then solves It has determined in the prior art due to that can not identify adjacent area downstream transmission direction, has been easy to produce so as to cause in dynamic TDD scene The problem of new interference type and down channel quality measurement result is out-of-date or fails.

Further, in the transmission time unit for carrying out the transmission of upstream or downstream data, the second base station is in the third time Window listens to third and eats dishes without rice or wine signal, and wherein third signal of eating dishes without rice or wine is eated dishes without rice or wine signal including at least first.Correspondingly, first base station is Three time windows send third and eat dishes without rice or wine signal.

In this way since the first signal of eating dishes without rice or wine includes second eating dishes without rice or wine signal and second base station of listening to of the second base station itself Exclusive signal of eating dishes without rice or wine, this third eat dishes without rice or wine signal include first eat dishes without rice or wine signal when so that first base station relative to the second base station and Speech, can equally play the role of repetition.This enables the second base station to get other base stations for being similarly Second Type Exclusive signal of eating dishes without rice or wine, so that first base station and the second base station can get the exclusive signal of eating dishes without rice or wine of peripheral base station, and So that first base station and the second base station can according to peripheral base station it is exclusive eat dishes without rice or wine signal acquisition to peripheral base station uplink and downlink Transmission direction.

In addition, further, in order to guarantee that adjacent base station can get the signal of eating dishes without rice or wine of other side each other, then every one second It is needed around base station there are first base station, otherwise the second base station will be unable to obtain adjacent base station information.

This scene is described in detail below.

At this time, it is assumed that in first transmission time unit, base station A, base station B, base station C and base station D are the second base station, That is base station A, base station B, base station C and base station D select to listen to the signal of eating dishes without rice or wine of other base stations in first time window, at second Between window send first and eat dishes without rice or wine signal.In this way due at this time in first time window, base station A, base station B, base station C and base station D All in state is listened to, it is in without base station and sends eat dishes without rice or wine signal condition, therefore base station A, base station B, base station C and base station at this time Any one base station cannot all listen to the signal of eating dishes without rice or wine of other base stations transmission in tetra- base stations D.

First, can configure by OAM, the first base station in cell site topology relationship and the second base station are configured.Such as it can be with Configuration base station B and base station C is first base station, and base station A and base station D are the second base station, in this way in first base station in first time window The exclusive signal of eating dishes without rice or wine of first base station itself mouthful is sent, listen to the transmission of the second base station in the second time window first is eated dishes without rice or wine letter Number, and the second base station listens to the exclusive signal of eating dishes without rice or wine of the first base station of first base station transmission itself in first time window, the Two time windows send first eat dishes without rice or wine signal when, can guarantee base station B and base station C the second time window listen to base station A and What base station D was sent first eats dishes without rice or wine signal, and can guarantee that base station A and base station D can listen to base station B hair in first time window The exclusive signal of eating dishes without rice or wine that exclusive eat dishes without rice or wine signal and the base station C sent is sent.

Third, can also monitor in the first time window of the first Preset Transfer time quantum, if can listen to The exclusive signal of eating dishes without rice or wine of first base station itself；When can listen to first base station itself it is exclusive eat dishes without rice or wine signal when, according to default Period periodically changes the operating mode of the second base station；When can not listen to first base station itself it is exclusive eat dishes without rice or wine signal when, The operating mode of the second base station of random change, and work as and monitor that the first base can be listened in the second Preset Transfer time quantum Stand itself exclusive eat dishes without rice or wine signal when, according to predetermined period, periodically change the operating mode of the second base station；Wherein, week is preset Phase includes at least one transmission time unit, and the second Preset Transfer time quantum is greater than the first Preset Transfer time quantum；Work Operation mode includes: to listen to the exclusive signal of eating dishes without rice or wine of the first base station of first base station transmission itself in first time window, second Time window sends first and eats dishes without rice or wine signal, and listens to third in third time window and eat dishes without rice or wine the third operating mode of signal；And The exclusive signal of eating dishes without rice or wine of the second base station itself is sent in first time window, listens to first base station transmission in the second time window 5th eats dishes without rice or wine signal, and sends the 6th the 4th operating mode for eating dishes without rice or wine signal in third time window；Wherein, it the 6th eats dishes without rice or wine signal It eats dishes without rice or wine signal including at least the 5th.

Specifically, when the second base station monitors can be listened into the first time window in the first Preset Transfer time quantum To first base station itself it is exclusive eat dishes without rice or wine signal when, illustrate that there are first base stations around the second base station, at this time only need to be according to default Period periodically changes the operating mode of the second base station.Certainly, predetermined period can be at least one Preset Transfer time Unit.Correspondingly, first base station first is eated dishes without rice or wine signal what the second time window can listen to the transmission of the second base station at this time, then First base station also only need to periodically change the operating mode of first base station according to identical predetermined period.

This scene is illustrated below.

For example, it is assumed that predetermined period is a Preset Transfer time quantum, base station B and base station C are first base station, base station A It is the second base station with base station D, and operating mode of the base station B and base station C in the first Preset Transfer time quantum is the first work The operating mode of mode, base station A and base station D in the first Preset Transfer time quantum is third operating mode, i.e., pre- first If in transmission time unit, base station B and base station C are in the exclusive signal of eating dishes without rice or wine of first time window transmission base station itself, base station A The base station that exclusive eat dishes without rice or wine signal and the base station C of the base station of base station B transmission itself are sent is listened in first time window with base station D The exclusive signal of eating dishes without rice or wine of itself, base station A and base station D send first in the second time window and eat dishes without rice or wine signal, base station B and base station C The second time window listen to the first of base station A transmission eat dishes without rice or wine that signal and base station D send first eat dishes without rice or wine signal, base station B and Base station C sends third in third time window and eats dishes without rice or wine signal, and base station A and base station D receive base station B hair in third time window The third the sent third that signal and base station C are sent of eating dishes without rice or wine is eated dishes without rice or wine signal.At this point, the operating mode of periodically the second base station of change, And periodically change the operating mode of first base station, i.e., in the second Preset Transfer time quantum, by the Working mould of the second base station Formula is changed to the 4th operating mode by third operating mode, and the operating mode of first base station is changed to by the first operating mode Two operating modes.I.e. in the second Preset Transfer time quantum, base station A and base station D send base station sheet in first time window The exclusive signal of eating dishes without rice or wine of body, base station B and base station C the 4th eat dishes without rice or wine signal and base what first time window listened to base station A transmission What the D that stands was sent the 4th eats dishes without rice or wine signal, and base station B and base station C send the 5th in the second time window and eat dishes without rice or wine signal, base station A and base Stand D the second time window listen to the 5th of base station B transmission eat dishes without rice or wine that signal and base station C send the 5th eat dishes without rice or wine signal, and base The A and base station D that stands sends the 6th eat dishes without rice or wine signal, base station B and base station C in third time window and in third time window listens to base The A that stands send the 6th eat dishes without rice or wine that signal and base station D send the 6th eat dishes without rice or wine signal.

In addition, specifically, when the second base station monitors into the first time window in the first Preset Transfer time quantum not Can listen to first base station itself it is exclusive eat dishes without rice or wine signal when, illustrate at this time may be used around the second base station there is no first base station To change the operating mode of the second base station at random, i.e. the second base station can change the Working mould of the second base station with a predetermined probabilities Formula.For example, it is assumed that predetermined period is a Preset Transfer time quantum, and the second base station is in the first Preset Transfer time quantum Operating mode be third operating mode, then operating mode of second base station in the second Preset Transfer time quantum can be with one Predetermined probabilities are changed to the 4th operating mode, i.e. operating mode of the second base station in the second Preset Transfer time quantum may be 4th operating mode, it is also possible to be maintained third operating mode.At this point, since the operating mode of the second base station is random change, Then it cannot be guaranteed that there are the second base stations to be changed to the 4th Working mould by third operating mode in the second Preset Transfer time quantum Formula then needs to continue at this time to change the operating mode of the second base station at random, until can in the second Preset Transfer time quantum Listen to first base station itself it is exclusive eat dishes without rice or wine signal when until, that is, exist the second base station in the second Preset Transfer time quantum Until when being changed to four operating modes by third operating mode, it can then proceed in predetermined period, periodically change the second base The operating mode stood correspondingly periodically changes the operating mode of first base station.

This scene is illustrated below.

For example, it is assumed that predetermined period is a Preset Transfer time quantum, and base station A, base station B, base station C and base station D are equal For the second base station, and the operating mode of base station A, base station B, base station C and base station D in the first Preset Transfer time quantum is Three operating modes.Base station A in this way, base station B, base station C and base station D can not listen to the exclusive letter of eating dishes without rice or wine of first base station itself Number, the operating mode of base station A, base station B, base station C and base station D can be changed at random at this time, until base station A, base station B, base station C and Until being changed to the 4th operating mode by third operating mode there are the operating mode of base station in the D of base station, it can then proceed in pre- If the period, the operating mode of the second base station is periodically changed, correspondingly, periodically changes the operating mode of first base station.

In this way monitoring that first base station sheet can be listened in the first time window of the second Preset Transfer time quantum Body it is exclusive eat dishes without rice or wine signal when, according to predetermined period, the operating mode of the second base station is periodically changed, so that the work of the second base station Operation mode can be changed according to predetermined period, so that first base station and the second base station can play mutually the work of repetition With so that first base station and the second base station can get the exclusive signal of eating dishes without rice or wine of period base station, so that first Base station and the second base station can be according to the exclusive signal acquisitions of eating dishes without rice or wine of peripheral base station to the downstream transmission direction of peripheral base station.

In addition, further, as shown in fig. 6, for the detailed step flow chart of the communication means applied to the second base station.It should Communication means further includes following steps:
