According to various execution mode, whether two pairs of equipment that the prior information of the beamforming training result among the equipment during supplying method is Network Based is assessed with directional transmissions can be used simultaneously in space reuse.

Fig. 7 display is for illustrating the flow chart 700 of the method for the initial assessment shared according to the space of an execution mode.

After step 702 starts, the beamforming training result among any two available devices in network (source device a and destination equipment b) is used to set up form in step 704, the best fan-shaped S (a, b) that this form display source device a selects.In following illustrative execution mode, set up the beamforming training result among any two available devices that form 1 shows in the network 600 described in figure 6.

In step 706 place, select two pairs of equipment (A, B) and (C, D) to assess them whether can simultaneously for space reuse.

Two pairs of equipment (A, B) of display in Given Graph 6 and (C, D), set up the interim form 2 of the beamforming training result being used for display device A, B, C and D at 708 places.

In step 710 place, restriction parameter δ=min [| S (a, b)-S (a, c) |, 12-|S (a, b)-S (a, c) |] select to two of two different destination equipment b and c best fan-shaped S (a to indicate by a source device α, b) the fan-shaped number difference and between S (a, c).The representative value of δ changes to 6 from 0.The selection of δ is the factor of the correctness level of the assessment determining space reuse.

In step 712 place, from (A, B, C, D), select source device, for whether the fan-shaped number difference δ of any two destination equipment inspections equals 00.If determine that the value of the δ of any two destination equipment equals 0, so do not advise that two pairs of equipment (A, B) and (C, D) space are shared 714.

Such as, for source device A, { (A, B), (C, D) } and, the value of the δ of { (A, B), (A, D) } is confirmed as { 1,2}.The δ value of source device is not equal to zero, and determines whether in step 716 place afterwards to check the institute's active equipment from equipment collection (A, B, C, D).If not, then process is back to step 712 with respectively by equipment B, when equipment C and equipment D is as source device, performs the process similar to source device A.

In the example of the beamforming training result based on form 2, determine that the value of the parameter δ of { (B, A), (B, C) } and { (B, A), (B, D) } is { 2,1} respectively; The value of the δ of { (C, D), (C, A) } and { (C, D), (C, B) } is { 1,2}; And the value of the δ of { (D, C), (D, A) } and { (D, C), (D, B) } is { 1,2}.Therefore determine that all values of δ are greater than 0, namely equipment (A, B) and (C, D) may can not disturb mutually.Therefore infer, share in the suggestion of step 718 place equipment (A, B) and (C, D) space in identical SP.

Said process can be understood as follows intuitively: as long as any two pairs of equipment do not fall within the territory, sector coverage area of mutual selection at source device and equipment place, destination, then can simultaneously by equipment to space reuse.

Wherein any two equipment to transmission conditions while of meeting above-mentioned (δ ≠ 0) and simultaneously all values of parameter δ be greater than in the another kind of situation of 1, allow more space to avoid the interference between directional transmissions simultaneously.Therefore, according to an execution mode, parameter δ can be used as the choice criteria of time slot scheduling or the time slot based on competition.

After the beginning at step 802 place, in step 804 place, PCT/AP is configured to process candidate SP _kand by δ * _kbe set to 0.If in order to planned transmission STA selects SP to (i, j), δ * _kbe defined as the minimum value of parameter δ.In other embodiments, if select SP to (i, j), δ * in order to planned transmission STA _kmean value or the aggregate values of parameter δ can also be restricted to.

In step 806 place, for candidate SP _kin each scheduled transmission to (x, y), determine whether best branch ID overlaps planned transmission to (i, j) and scheduled transmission between (x, y).Particularly, check S (x, i)==S (x, y) ∥ S (x, j)==S (x, y) ∥ S (y, i)==S (y, x) ∥ S (y, j)==S (y, x) ∥ S (i, x)==S (i, j) ∥ S (i, y)==S (i, j) ∥ S (j, x)==S (j, whether i) ∥ S (j, y)==S (j, i) is true.If so, so current candidate SP _kcan not be shared (x, y) (i, j) and scheduled transmission by planned transmission STA, and process turns back to step 804 to process next candidate SP _k.

If determine that planned transmission STA does not disturb between (x, y) (i, j) and scheduled transmission, so calculate the value of fan-shaped number difference δ in step 804 place.

In step 812 place, determine SP _kmiddle transmission collection (x, y) _ktraversal whether terminate.If no, so process is back to step 806 until SP _kin scheduled transmission to processed.

In step 814 place, utilize δ * _krespective value by SP _kadd initial SP Candidate Set { SP _k.

In step 816 place, check and determine existing SP collection { SP _ktraversal whether terminate.If no, so process is back to step 804 to process next candidate SP _kuntil all existing SP are processed.

In step 818 place, based on choice criteria from { SP _kselect best initial SP to select maximum δ * _kand in step 820 place terminal procedure.

Hereinafter by as in Fig. 9 request SP distribute STA in the example of (E, F), more detailed description said process.

The network 600 that Fig. 9 display is similar to the network 600 of Fig. 6, wherein STA asks PCP/AP to distribute SP to (E, F).In this illustrative embodiments, PCP/AP has and transmits (A accordingly, B) and transmission to (C, D) scheduling SP1 and scheduling SP2, and the STA A of display in foundation as above form 1, STA B, STA C, the form of the beamforming training result between any two in STA D, STA E and STA F.

Following display according to the flow chart of Fig. 8 from planned transmission to the distribution SP collection of (E, F) SP1, SP2} select the process of best initial SP:

(1) PCP/AP sets up the interim form 3 of STA (A, B, C, D) to check whether SP1 can be used for (E, F), and namely whether (A, B) and (C, D) can transmit simultaneously.From form 3, observe SP1 and taken by (A, B), wherein respectively A use its fan-shaped 1 and B use its fan-shaped 2.Now, E plan uses fan-shaped 3 and F plan uses fan-shaped 7 to intercom mutually respectively.

Suppose that A after the beam forming utilizes best fan-shaped 1 to transfer to B.Then the result assessed to E and F is disturbed.E or F can not affect by A, because the Wave beam forming result display fan-shaped 4 and fan-shaped 2 listed in form 3 is the preferably fan-shaped to transfer to E and F respectively of A, it is different that this and fan-shaped 1 of A transfer to B.And the value of the δ of { (A, B), (A, E) } and { (A, B), (A, F) } is calculated as { 3,1}.Therefore, the transmission of A does not disturb E and F.

But if B utilizes fan-shaped 7 to transfer to A, so E can be affected by B, this is because identical fan-shaped 7 can be selected to transfer to A and E for B.In this case, the δ of { (B, A), (B, E) } equals 0.

Therefore, (E, F) does not meet the condition utilizing the space of scheduling SP1 to share.

(2) then, PCP/AP checks SP2.

In a similar manner, PCP/AP sets up another interim form 4 of STA (C, D, E, F) to check whether SP2 can be used for (E, F).

In this example, for STA C, S (C, D)=10 are different from S (C, E)=8 and S (C, F)=12.The fan-shaped number difference δ of { (C, D), (C, E) } and { (C, D), (C, F) } is given as { 2,2}.For STA D, S (D, C)=4 are different from S (D, E)=5 and S (D, F)=3.The fan-shaped number difference δ of { (D, C), (D, E) } and { (D, C), (D, F) } is given as { 1,1}.And for STA E, S (E, F)=3 are different from S (E, C)=4 and S (E, D)=1, and { (E, F), (E, C) } and { (E, F), δ (E, D) } is given as { 1,2}.For STA F, S (F, E)=7 are different from S (F, C)=6 and S (F, D)=9, and { (F, E), (F, C) } and { (F, E), δ (F, D) } is given as { 1,2}.

Therefore, can advise that SP2 is the initial SP candidate of (E, F).

Form 4: to locking equipment collection { the beamforming training result between C, D, E, F}

(3) last, utilize existing SP2 as preferably initial SP, PCP/AP in response to E and F.

Figure 10 display has the network 1000 of multiple STA.Based on Figure 10, if describing according to another execution mode SP1 and SP2 is hereinafter all suitable candidate SP, how to be that planned transmission is to selection preferably initial SP candidate.

In the execution mode of Figure 10, each STA can have 24 fan-shaped, each fan-shaped transmission of angle with the directional transmissions of 15 degree.Following form 5 shows equipment { equipment { the beamforming training result of C, D, E, F} in A, B, E, F} and SP2 in SP1.For planned transmission selects the process of preferably initial SP candidate as described below to (E, F).

Equipment collection { equipment collection { the beamforming training result of C, D, E, F} in A, B, E, F} and SP2 in form 5:SP1

(1) first, PCP/AP checks SP1.According to form 5, (A, B) does not disturb (E, F), because they preferably distribute, number does not have overlap.In this embodiment, because each STA have 24 fan-shaped, by min [| S (a, b)-S (a, c) |, 24-|S (a, b)-S (a, c) |] determine parameter δ, to indicate by selecting to two of two different destination equipment b and c best fan-shaped S (a from a source device α, b) the fan-shaped number difference and between S (a, c).Usually, in other embodiments, if STA has N number of fan-shaped, by min [| S (a, b)-S (a, c) |, N-|S (a, b)-S (a, c) |] determine that parameter δ is to indicate two best fan-shaped S (a, b) the fan-shaped number difference and between S (a, c).

According to form 5, { all values of the δ of A, B, E, F} are greater than 2 to equipment collection.Particularly, { (A, B), (A, E) } and { (A, B), (A, F) }; { (E, F), (E, A) } and { (E, F), (E, B) }; All values of the δ of { (F, E), (F, A) } and { (F, E), (F, B) } are 3.Therefore, SP1 will be added in the initial SP Candidate Set of (E, F).

If be that (E, F) selects AP, so limiting δ * is the minimum value of δ.Then the δ * of SP1 is 3.

Although δ * is depicted as the minimum value of δ in this embodiment, be to be understood that in another embodiment, δ * can be defined as mean value or the aggregate values of δ, if be that planned transmission selects SP to (E, F).δ * can represent the equipment collection { degree of the coupling between the best branch number of A, B, E, F}.The much higher value of δ * can represent the comparatively low degree of the coupling between best branch number (can correspond to the beam communication characteristic described in above-mentioned execution mode), and can indicating equipment collection { the lower possibility of the interference between A, B, E, F}.

(2) secondly, PCP/AP checks SP2.Can be competent at and the space reuse of (E, F) according to form 5, SP2, this is because equipment collection { the preferably distribution number between C, D, E, F} does not have overlap.{ all values of the δ of C, D, E, F} are equal to or greater than 1 to equipment collection.Particularly, { (C, D), (C, E) } and { (C, D), (C, F) }; { (D, C), (D, E) } and { (D, C), (D, F) }; { (E, F), (E, C) } and { (E, F), (E, D) }; All values of the δ of { (F, E), (F, C) } and { (F, E), (F, D) } are 1 or 5.The δ * of SP2 is 1, is the minimum value between 1 and 5.

Therefore, SP2 also can be added in the initial SP Candidate Set of (E, F).

(3) the three, PCP/AP { select best one from Candidate Set in SP1, SP2}.In one embodiment, choice criteria is the SP of the maximum with δ * is best SP.From (1) and (2), the δ * of SP1 and SP2 is given as 3 and 1 respectively.Therefore, select SP1 as the preferably initial SP candidate of (E, F).

(4) final, PCP/AP utilizes SP1 preferably initial SP as a result to respond E and F.

The method described in various execution mode is above based on the prior information of the training Wave beam forming result between equipment, the equipment of search in directional transmissions best existing right, this preferably existing to sharing space with the equipment of planned transmission in directional transmissions with minimum communication to disturbing.Following advantage is realized by various execution mode:

-equipment between the correct distribution of space reuse;

-equipment between the fast allocation of space reuse;

-avoid those equipment between measurement and the unnecessary operation of reporting feedback, if equipment transmits simultaneously, these unnecessary operations can cause mutual interference; With

Because can reduce widely for measuring the quantity right with the equipment of reporting feedback, so the energy saving of Resourse Distribute that conserve space is reused.

Execution mode provides the directional transmissions utilizing and spatially can share transmission channel in a slot, utilizes and has the directed defeated planned transmission equipment pair passed, identify the method that best existing equipment is right.In one embodiment, the method can comprise:

Background technology

Multiple standards technology, comprises the IEEE802.11ad draft developed, and standardized IEEE802.15.3c and standardized ECMA-387 is for target with gigabit (Gagibit) short range communication system.Recently, national information technical standard (National Information Technology Standardization, NITS) Chinese wireless personal domain network (the China Wireless Personal Area Network under, CWPAN) working group is devoted to technical solution with nearest based on millimeter (millimeter, the mm) wave band of China's issue.

Because in the transmission of this millimeter wave, path loss can be considerably large, so for such communication system, uses directional antenna to be very important, to obtain enough link budgets and to realize suitable communication range.And directional transmissions also causes the possibility realizing sharing in the space in network between each equipment, and thus increases network throughput widely.Such as, the multiple Wireless Telecom Equipments 102,104,106,108 in Fig. 1 display communication network 100.First Wireless Telecom Equipment 102 is in the beam communication 110 of the second Wireless Telecom Equipment 104, and the 3rd Wireless Telecom Equipment 106 is in the beam communication 112 of the 4th Wireless Telecom Equipment 108.In order to the space realizing multiple equipment room is shared, need to determine whether the directional transmissions 110,112 between two pairs of Wireless Telecom Equipments is disturbed mutually.

For medium access control (medium access control, MAC) many challenges to be processed are had, such as device discovery and beamforming training, wherein equipment needs the direction of the communication found between equipment, the access scheme based on competition in directionality exists and at how development space and frequency reuse in the beam communication.

" equipment " is widely used in the node described in network.In IEEE802.11ad network, " stand (Station, STA) " is generally used for describing the node in IEEE802.11 network.In this article, " equipment " is for the general description of network, and " STA " is for IEEE802.11ad network.

In the draft of IEEE802.11ad illustrates, Wave beam forming is that STA is to the mechanism being used for realizing necessary beam transmission link budget.Beamforming training is the two-way result of beamforming training frame transmission, and the transmission of beamforming training frame provides necessary signaling to allow each STA to determine transmission and to receive the appropriate antenna Operation system setting of two.After being successfully completed of beamforming training, allegedly set up Wave beam forming.

The beamforming training described in IEEE802.11ad draft illustrates has two stages: fan-shaped horizontal sweep (Sector level sweep, SLS) and bundle refinement agreement (Beam Refinement Protocol, BRP).

The example of Fig. 2 display for illustrating fan-shaped horizontal sweep (SLS) beamforming training used in IEEE802.11ad.Particularly, Fig. 2 display is used for the transmission sectoring (transmit sector sweep) of simple beamforming training and receives the example of sectoring (receive sector sweep).The object of SLS is make the communication between two STA participated at lower rate transmissions place become possibility.Usually, the SLS stage only provides transmission beam to form training, indicated by the TX sectoring in Fig. 2.If one in the STA participated in is selected only to use a transmit antenna pattern, receive the part that training can perform the SLS indicated by the RX sectoring in such as Fig. 2.The object in BRP stage is receiver is trained become possibility and make the iterative refinement of the transmitter at STA place and the antenna weight vector of receiver participated at two become possibility.

In TX sectoring, beamforming training frame is transferred to STA and the feedback that will receive on the best direction communicated with STA from receiving STA by individual infrastructure service set (Personal Basic Service Set, PBSS) control point (PCP) as network-based control device in a different direction.In this article, for simplicity, fan-shaped ID is for relating to transmission STA to the best transmission direction receiving STA.

Similarly, in RX sectoring, transmission STA transmits in multidirectional mode, receives STA and receives in different directions in turn.Reception STA knows the best direction for communicating with transmission STA, namely best fan-shaped ID.

According to above, it is said that the beamforming training result of the best fan-shaped ID that Wave beam forming utilizes STA right is set up.

In the draft of IEEE802.11ad illustrates, the strategy of space reuse is for perform and report is measured assess possibility shared and for AF panel to perform space.And, propose only the seeervice cycle (SP) to be considered as space reuse in IEEE802.11ad.

In this article, assessment will be dispatched with other that space of (or existing) SP is shared or is considered as the SP be reallocated in beacon interval (beacon interval, BI) and be called candidate SP.Simultaneously may have multiple candidate and existing SP, and SP can depend on that space is shared and this paper of interference assessment and suppose the role of candidate and existing SP simultaneously.

To participate in SP and the hypothesis of STA that support space is shared is that STA should perform beamforming training mutually before identifying oneself with this strategy or performing any measurement.

Fig. 3 display is for illustrating that Figure 30 0 of the example of assessment is shared in the space used in IEEE802.11ad.In this example, SP1 is the existing SP between STA A and STA B, and SP2 is the candidate SP between STA C and STA D.After STA C and STA D has the Wave beam forming of mutually training, the object that PCP/AP (accessing points) shares in order to the space in existing SP and request of transmitting to STA C and STA D to perform measurement.The existing SP for the transmission between STA A and STA B duration, STA C and STA D performs measurement.Measurement report feeds back to PCP/AP.As a result, PCP/SP ask STA A and STA B candidate SP (SP2) duration perform measurement, participant SP (SP2) duration in, STA C intercoms with STA D phase.Corresponding measurement result also can feed back to PCP/AP.Then, PCP/AP determines whether have any interference to occur.If do not have the SNR disturbing or receive to be greater than threshold value, so PCP/AP can agree to candidate SP (SP2) is converted to existing SP to realize sharing with the space of existing SP (SP1).

Above-mentioned example indicates the basic conception of the current strategies of the space reuse used in IEEE802.11ad for " attempt and use ", namely first performs and measures and determine whether candidate SP can be converted to existing SP and reuse with implementation space.But it seems from the angle of PCP/AP, this is a kind of selection course of blindness.When STAC and STA D request resource, not for the prior information of PCP/AP to distribute the STA that can be shared by space to the suitable SP used simultaneously.If PCP/AP selects existing SP blindly and request performs measurement and feedback report, then when there being many existing SP and candidate SP in a network, this operation can become concentrated.This can make PCP/AP be inefficent for the resource that allocation space is reused.
