Description

The method of communication device and operation communication device
Technical field
In general, the present invention relates to a kind of communication devices and a kind of method for operating this communication device.More specifically, this hair It is bright to be related to a kind of communication device that carry out beam forming and a kind of method for operating this communication device.
Background technology
Beam forming (Beamforming, BF) is well-known, it is widely adopted in multiple antenna communication Space filtering signal processing technology is (for example, with reference to B.D.Van Veen and K.M.Buckley " beam formings：One kind is for sky Between the universal method that filters, " IEEE Acoustics, Speech and Signal Processing Magazine, vol.5, No.2, pp.4-24, Apr.1988).BF is conventionally used to radiate/receive energy to/from the specific position in space or be equal Ground decays to the/signal from particular spatial location.BF is the Emerging wireless communications system for being operated in high frequency band One of most popular technology of physical layer, such as microwave and millimeter wave frequency band, and it has been considered for access and backhaul communication. BF in such a system universal, which is primarily due to it, efficiently to realize that this is phased with large-sized phased antenna array Aerial array is capable of providing big BF gains, also referred to as generous tropism gain, has small and cheap individual antenna element.
In the high-frequency wireless communication link with sight (LOS) component especially between two network nodes A and B, The two network nodes A and B is equipped with large-size antennae array and can realize BF technologies, in fact it could happen that problems with. As described above, when node A is to the direction radiation energy of node B, and the latter is radiated its direction from node A and receives energy, Big BF gains can be obtained, vice versa, i.e., when the wave beam at wireless communication link both ends is in geometric alignment.Work as network node When A or B or only their aerial array are mobile or change position/orientation, they may stop from the BF wave beams obtained For geometric alignment to acceptable level, this would generally reduce the performance of their communication link.Misalignment is bigger, and hydraulic performance decline is got over Seriously.When disposing high directivity narrow beam at node A and node B, the problem of being referred to as wave beam misalignment, becomes more frequency It is numerous, and its influence to link performance is more unfavorable.Using high directivity narrow beam in high-frequency wireless communication system, with confrontation Signal of communication further serious signal attenuation due to distance incremental between communication ends.Working frequency is higher, and communication system is got over It is susceptible to path loss.Therefore, in such a system, need to design and using steady wave beam technique of alignment.
S.Hur etc. is in " wireless backhaul and the millimeter wave beam forming of access in small cell network " (IEEE Transaction on Communications, vol.61, no.10, pp.4391-4403, Oct.2013) in, it has been suggested that The wave beam technique of alignment that using sub-codebook collection adaptive is sampled to channel subspace.This hard technique of alignment is any It using one group of candidate beam directional mode at two communications wireless network nodes, and is scanned for ping-pong type, i.e., to take turns more Form between the node for a pair of of beam pattern, maximizes the signal-to-noise ratio (signal-to-noise of communication link Ratio, SNR) performance.
J.Wang etc. exists, " the beam forming agreement based on wave beam code book for being used for more Gbps millimeter waves WPAN systems " (IEEE Journal on Selected Areas in Communication, vol.27, no.8, pp.1390-1399, Oct.2009 it proposes to pass through a three-level BF agreement in), between establishing wireless network node in 60GHz wireless personal area networks Communication.In this article, wave beam grade is carried out from the predefined set of the directional mode (also referred to as BF code books) of wave beam Search is aligned including wave beam, replaces the exhaustive beam search between any pair of communication network node.
J.Song etc. is in " the adaptive millimeter wave wave beam alignment of dual polarization mimo system " (ar Xiv preprint ar Xiv：1408.2098v2, Jan.2015) in soft-decision using dual polarization channel has been proposed for millimeter wave wireless communication Wave beam technique of alignment.This two benches technology based on channel subspace estimation is combined is adopted using the subspace of training wave beam Sample, followed by the post-processing stages being made of the alignment of two-wheeled wave beam.
R.Maiberger etc. is in " location-based beam forming " (Proc.IEEE 26th Convention of Electrical and Electronics Engineers in Israel, Eilat, Israel, 17-20Nov.2010, Pp.184-187 in), it is proposed that create transmitting BF using location data for the reception network node of LOS wireless communication systems The BF technologies of vector (i.e. launching beam).According to this technology, single antenna reception expected from the estimation of multi-antenna transmission network node The position of machine node is vectorial to build transmitting BF.Angle of arrival estimation technique, global positioning system (global can be used Positioning systems, GPS) reading or location-based advertisement perform the location estimation of receiving node.
In IEEE, the complete motion specifications of PHY/MAC (T Gad D0.1), IEEE 802.11-10/0433r2Std., 2010 In describe the unilateral beam search of the wireless network node with large-size antennae for WLAN.
In IEEE 802.11ad, WLAN real time media access control (LAN MAC) and physical layer (PHY) specification In-amendment 3：The enhancing (2012) of ultra-high throughput contains the two benches for WLAN in 60GHz frequency bands Beam search technology.According to the technology, the sector-level scanning of coarseness is first carried out, followed by wave beam grade align stage.It is all The exhaustive searches in possible transmission and reception direction are applied in each rank.
It is had been proposed in 6417803 B1 of US a kind of for correcting transmitting antenna and reception antenna on mobile platform Between antenna beam misalignment device and method.In the art, in order to correct wave beam misalignment, it is proposed that any two Sequence antenna beam control at a communication network node.
One kind has been proposed in US 2013/0229309, omnidirectional is used at any two communications wireless network node The beam alignment of BF code books.According to this method, a network node uses one group of predefined BF pattern or beam direction It is to be used that sexual norm and its desired communications reception node indicate which wave beam needs.The latter node by sending out in the codebook It send and has the feedback of selectable wave beam entrance to notify previous BF patterns to be used.
It has been proposed a kind of manipulating microwave backhaul including one or more sensors in US 2014/0347222 Multiple antenna transceiver framework.The sensor can export can be used for adjust transceiver phase and/or range coefficient reading/ Measured value.
A kind of dress for wave beam to be maintained to be aligned in a wireless communication system is provided in 2014/0056256 A1 of US It puts and method.According to this method, network node is sent using one group of predefined BF pattern or beam direction sexual norm, and work as When the quality of its communication link with receiving network node is less than some threshold value, the latter's node feeding back meets their communication link Quality requirement preferred BF patterns.
It is had been proposed in 2010/0124210 A1 of US a kind of using GPS guiding and the preloading position of access point (AP) The radio-frequency transmissions put and the method for receiving BF.In this way, any wireless device for being desirably connected to network all has net The position of network AP, and it is connected to one of which using its GPS data.Connection to network is intended to be connected to its node By calculating the relative vector with one of AP, one of right backward selection sends detection packet to realize.In order to which this is counted It calculates, wireless device obtains its position by GPS.Next, the AP of selection estimates its link condition with wireless device, by it Wave beam guides it into and is sent to grouping to establish desired connection.
It has been proposed in 2010/0124212 A1 of US a kind of being similarly used for very much radio-frequency transmissions and receiving BF Method.According to 2010/0124212 A1 of US, it is desirable to which the wireless device for being connected to the AP of network has by GPS and electronic compass group Into alignment system.In addition, AP broadcasts its position.Then, equipment calculates the relative vector between its position and AP positions, then It is sent to detection grouping.Next, AP estimates its channel conditions with wireless device, by its beam steering it, and to its Grouping is sent to establish desired connection.
Although above-mentioned wave beam technique of alignment can provide some improvement, but still there are some shortcomings.For example, based on unilateral side The beam search technology of code book is generally not suitable for high-frequency wireless communication system, wherein two communication ends using narrow beam and It needs to be aligned as accurately as possible.In the wave beam technique of alignment based on bilateral code book, wave beam is to select usually will will be any It rattles and exchanges into more wheels of row information between the wireless network node of two communication.This operation mode cause high computation burden with And the great expense incurred of table tennis signaling.Additionally, it has been found that perform poor under low SNR value, that is, there is very high wave beam misalignment Possibility.Therefore, the Present solutions for wave beam alignment are unsuitable for high-frequency wireless communication system, are not suitable for any two Between a communication node provide acceptable level wave beam alignment and/or need high computation complexity and for communication node it Between table tennis signaling large overhead.Therefore, it is necessary to a kind of improved wave beam technique of alignment.

In one embodiment, communication device 100a and another communication device 100b can be with by with LOS components The form of two multiple antennas network nodes 100a, 100b of high-frequency wireless communication link (such as microwave or millimeter wave link) communication To realize.Node 100a, 100b can be moved, and each node 100a, 100b can have on fixed routing track A certain number of predefined beam direction sexual norms.When the quality of their communication link is horizontal less than minimum needs, often A node 100a, 100b measure the position of its position or its aerial array 101a, 101b and forward it to network controlling entity, Especially with dedicated low frequency transceiver system, such as communication interface 103a, which, which safeguards, has communication section The look-up table 109a of the performance indicator of link between point 100a, 100b, the performance indicator are used for node 100a, 100b two The predefined beam direction sexual norm and node 100a, 100b or its aerial array 101a, 101b of person is in fixed route track On replacement position various combination.Next, network controlling entity is searched in look-up table 109a generates acceptable performance A pair of of beam direction sexual norm, the indicator of each beam direction sexual norm is then forwarded to each node 100a, 100b, Each node 100a, 100b is caused to use corresponding beam direction sexual norm.
In one embodiment, communication device 100a is realized in the form of node A, and another communication device 100b is with node The form of B realizes that interior joint A is considered as host node, and node B be considered as from node, two nodes be all present in as In two-dimensional space shown in Fig. 4.It is easily that this, which realizes that example expands to three dimensions,.Consider each node 100a, 100b is mounted on bar, and assumes that two bars can all be waved due to wind or ground vibration.Since bar waves, network node Both 100a and 100b are moved along any direction, but can be in the limitation of the particular displacement of the material according to bar and structure.At this In a example, the bar swing more than the limitation of these particular displacements may cause bar to be broken, this is considered as extreme case.Network section Point 100a and 100b disposes one or more instrumentation/sensors for being used for position/displacement monitoring, such as position sensor 102a, And additional low frequency regular transceiver system, such as communication interface 103a, for exchanging BF information, for example, using wave beam side Position/displacement to sexual norm and node 100a, 100b.Once in node 100a, communication link is set between 100b, it is assumed that it Initial distance d0, i.e., it is accurately measured in moment t=1, is reached using the instrument of for example one or more high precisions To this purpose.Obtaining distance d0Later, using exemplary coordinate system shown in Fig. 4, wherein origin by host node 100a position Put definition.Particularly, (0,0) point of the two-dimensional coordinate system in Fig. 4 is the location point M of host node 100a0 (A), and from node The position of 100b is by with coordinate (0, d0) point M0 (B)Definition.Node in the two-dimensional coordinate system of t ＞ 1 at any time, Fig. 4 The position of 100a is by point Mt (A)Coordinate provide, the position of node 100b is by point Mt (B)Coordinate provide, dtRepresent moment t's Nodal distance.For example, as shown in figure 4, before moment t=1, host node 100a is from position M0 (A)It is moved to coordinate (- x1 (A), y1 (A)) new position M1 (A), and from node 100b from position M0 (B)It is moved to coordinate (x1 (B), d0-y1 (B)) new position M1 (B).Therefore, in the exemplary embodiment, tie point M1 (A)And M1 (B)Line segment angle ζ1It can be calculated as follows：
Therefore, in order to which each node 100a, 100b is made to calculate the direction in the direction to another node, i.e. steering wave beam, The position coordinates of each node needs two nodes 100a, 100b and the initial range of node 100a, 100b, i.e. d0。
In one embodiment, network node 100a, the position of 100b can be defined as its aerial array 101a, 101b Center position, and distance refers to the distance between the aerial array 101a of node 100a, 100b, center of 101b. Even if one or more instrumentation/sensors of monitoring position/displacement and/or the one of the distance between measuring node 100a, 100b A or multiple instruments are not attached to the center of the aerial array 101a, 101b of node 100a, 100b, and are attached to node The other parts of 100a, 100b or the bar of supporting node 100a, 100b, still can calculate aerial array 101a, 101b's The position at center, as being appreciated that from following example.Assuming that in the two-dimensional coordinate system of Fig. 4 of moment t, major network The position at the center of the aerial array 101a of network node 100a is provided by coordinate (a, b).Due to the shape of the structure of node 100a It is known, the i.e. overall geometry of node 100a, so node 100a can from any movement/displacement of initial point (0,0) To be converted into movement/displacement of the center a of its aerial array 101a.Therefore, in node 100a, position/displacement of 100b with There is determining relationship between the position/displacement at the center of the aerial array 101a, 101b of node, thus term node 100a, Position/the displacement at the center of position/displacement of 100b and the aerial array 101a, 101b of node is used interchangeably herein.
Referring back to the embodiment described in the context in Fig. 4, host node 100a and can be at it from node 100b Look-up table is preserved in memory, look-up table 109a as escribed above has the SNR performances of the link between node 100a, 100b Indicator, the performance indicator for the predefined beam direction sexual norm of two nodes 100a, 100b and they and/or All combinations of replacement position/displacement of their aerial array 101a, 101b.For the two-dimensional example shown in Fig. 4, Fig. 5 The K predefined beam direction sexual norms and two nodes of two nodes 100a, 100b are given in shown table M replacement position/displacements of the 100a and 100b in x-axis and the exemplary look-up table Γ of N number of replacement position on the y axis.It is logical Often, the quantity of the predefined beam direction sexual norm between node 100a, 100b and/or the quantity of replacement position/displacement can To be different.Exemplary look-up table Γ shown in Fig. 5 is the mxn matrixes for having m=n=KMN, and symbol ΓI, jIt represents (i, j) a element of Γ, wherein i=1,2 ..., m and j=1,2 ..., n.In table shown in Fig. 5, symbol Xe (A)With Xe (B)E-th replacement position/displacements of expression the node 100a and 100b in x-axis respectively, and Yc (A)And Yc (B)It is represented respectively with e On the y axis c-th replacement position/displacement of node 100a and 100b, wherein e ∈ { 1,2 ..., M } and c ∈ 1,2 ..., N}.In addition, bn (A)And bn (B)N-th of predefined wave beam side of the aerial array 101a, 101b of node 100a and 100b are represented respectively To sexual norm, wherein n ∈ { 1,2 ..., K }.
It provides to predefine wave during the host node 100a shown in Fig. 4 and K=5 from node 100b in figure 6 and figure 7 The example of beam directional mode.These beam direction sexual norms are by 60 and 120 degree of node 100a and node 100b Uniform sampling in 240 and 300 degree obtains.
In one embodiment, to both node 100a and 100b, common available look-up table Γ 109a are in initial calibration It is built in stage, two of which node 100a, 100b are placed on M different position of the x-axis along coordinate system shown in Fig. 4 Put/displacement and N number of different location/displacement of the y-axis along coordinate system shown in Fig. 4.Channel radio between node 100a, 100b The SNR performances for believing link are that position/displacement of node 100a, 100b and the various combination of predefined beam direction sexual norm are surveyed Amount.In principle, the entry number in look-up table 109a will increase with the quantity of said combination.Look-up table with increased in size Therefore 109a is converted to for the increasing in terms of the SNR performance indicators of different location/displacement and predefined beam direction sexual norm The resolution ratio added.In general, the size of common available look-up table 109a can depend on application, more specifically：I) certain Increased resolution ratio in special angle sector may be needed in.(such as see Fig. 4, Fig. 6 and Fig. 7, interior joint 100a and 100b is placed with to be turned to each other, and even if as node 100a, when 100b slightly moves (due to wind or ground vibration), is also needed Ensure that wave beam is aligned.), which reduce the free space of sampling, and so that Sizes (the as above institute of look-up table 109a It states, in one embodiment, look-up table 109a can be with trustship with increased storage and the network control of big data recovery capability System is physically rather than trustship is in node 100a, 100b)；Ii) size of inquiry table 109a can for extreme position/displacement To keep reasonable, and occur not including in look-up table 109a (position measured can be used in this case during position/displacement Putting/be displaced to available replacement position/displacement has how close one or more threshold values), it can be by node 100a, 100b Between switching node 100a, 100b practical measurement position/displacement come complete wave beam alignment；And iii) regularly update fixation The content of the look-up table 109a of size, with two network node 100a of Dynamical capture, the environment that 100b is being operated.
In one embodiment, when host node 100a and instantaneous SNR value from the wireless communication link between node 100b Drop to minimum SNR threshold gammasth(i.e. the first mass measurement threshold value) below when, it is believed that occur wave beam misalignment.The threshold value can be with Depending on specifically applying and reflecting the required service quality level of communication link.For monitoring node 100a, between 100b Link instantaneous SNR performances, one or two in node 100a, 100b can measure SNR performances in each moment t, and Obtain the estimated value g of instantaneous SNR performancest.In order to which sending node is made to know and the communication link of expected receiving node in moment t SNR is provided in one embodiment by the SNR value g of estimationtThe former feedback is sent to from latter node.This feedback behaviour Work can carry out in the following manner：i)gtThe normal feedback of value, it may be possible to its quantised versions；Or ii) tdd systems In special signal from receiving node to sending node, so that the latter estimates the SNR value of their communication link.In an implementation In example, g can be exchanged using communication interface 103atValue, to ensure reliably to exchange.
In one embodiment, first, host node 100a is in gt＜ γthShi Faqi a series of actions, then when needed It follows since a series of actions of node 100b.If still gt＜ γth, then can use and carry out the last of autonomous node 100a A series of actions.In one embodiment, can using following three phases come realize communication network node 100a and 100b it Between the alignment of acceptable wave beam it is horizontal：I) 1 (MR1) stage of main recovery；Ii) from recovery (SR) stage；And iii) it is main restore 2 (MR2) stage.Hereinafter, for the sake of clarity, index is used in the signal exchanged between node 100a and 100b, so as to Instruction includes BF information (beam direction sexual norm and seat used in node 100a, 100b or its aerial array 101a, 101b Mark or relative coordinate) pure control signal of communication or data-signal including data and/or above-mentioned BF information.
The step of summarizing the embodiment in the MR1 stages occurred at host node 100a in the flow chart of figure 8.In the figure In following figure, there is the b of s ∈ { 1,2 ..., K }s (A)And bs (B)The aerial array 101a, 101b of node A and B are represented respectively Selected predefined beam direction sexual norm generates acceptable SNR performance levels (as described above, K represents available BF patterns The quantity of the element of set).B is used respectivelyopt (A)And bopt (B)Represent the node 100a for being designed to turn to another corresponding node With the beam direction sexual norm of the aerial array 101a, 101b of 100b.gmaxIt represents to use all available predefined beam directions The maximum S/N R performances that sexual norm is measured in particular moment at one of node 100a, 100b places.
Host node 100a, which is can be seen that, from embodiment shown in Fig. 8 estimates instantaneous SNR value gt, and and if only if gt＜ γthWhen Follow following action (reference numeral 801 of Fig. 8).Whenever gt＜ γth, host node 100a is from one or more instrument/sensing Device (such as position sensor 102a) obtains its current location/displacement information (reference numeral 803 of Fig. 8), and in its lookup Position/the displacement (reference numeral 805 of Fig. 8) replaced recently from its current location/displacement is found in table 109a).Calculating most connects A kind of method of near replacement position/displacement is measured using Euclidean distance.When the latter replaces position/displacement with coming from previous The BF information (the beam direction sexual norm used and position/displacement) of the slave node 100b of gap is used together, so as to host node 100a searches for predefined beam direction sexual norm in look-up table 109a and generates gt≥γth(reference numeral 807 of Fig. 8).Most Just, host node 100a can perform all available beam direction sexual norms sequential scans, and using meeting the of SNR requirements One or one of generation maximum S/N R performances.It is if there is this predefined beam direction sexual norm, i.e., if real It is horizontal acceptable wave beam alignment is showed, then host node 100a can be using it come to (Fig. 8's is attached from node 100b transmission datas Icon note 809 and 811).Otherwise, host node 100a can use its predefined beam direction sexual norm to generate for expected logical Believe the maximum S/N R performances of link, data are sent collectively to together with its BF information from the node 100b (reference numerals 809 of Fig. 8 With the beam direction sexual norm that 813), such as node 100a is used and its from its position that one or more instrumentation/sensors obtain Put/displacement information.In one embodiment, the BF information mentioned in the context of reference label 813 can be by means of communication Interface 103a is sent, and is preferably operated in low frequency.The data mentioned in the context of reference marker 813 can use day Linear array 101a is sent in high frequency.
For exemplary look-up table 109a shown in fig. 5, the BF information exchanges between communication node 100a, 100b need B A bit, wherein
In response in the control signal (attached drawing of Fig. 9 that the BF information with host node 100a is received at node 100b Label 901), it can enter the SR stages from node 100b and follow a series of actions shown in Fig. 9.Initially, from node 100b Its current position/displacement information (reference numeral 903 of Fig. 9) is obtained, and searching from one or more instrumentation/sensor It is found in table and the immediate available replacement position/displacement (for example, being measured using Euclidean distance) of its current location/displacement.This Outside, node 100b can use the position/displacement information received from host node 100a to come lookup and node in its look-up table The immediate available replacement position/displacement in current location of 100a.These of the two nodes 100a, 100b replace position/position Shifting is used together with by the information of predefined beam direction sexual norm that host node 100a is selected, to be looked into from node 100b It looks in table and searches for predefined beam direction sexual norm, generate gt≥γth(reference mark 905 of Fig. 9).If there is such That is, if having been realized in acceptable wave beam alignment level, it is used from node 100b for predefined beam direction sexual norm Come to host node 100a transmission datas (reference numeral 909 and 911 of Fig. 9).Otherwise, from node 101b uses from host node 100a Position/displacement information of reception turns to its optimal beam direction sexual norm (reference numeral 913 of Fig. 9) to design.If from Node 100b leads to g to the use of the beam direction sexual norm of the optimizationt≥γth, then the beam direction sexual norm be used for Host node 100a transmission datas (reference numeral 915 and 919 of Fig. 9).In addition, the beam direction sexual norm of the optimization with from node Position/displacement information of 100b and value gtIt is stored in together in look-up table so as to the look-up table of perfect/more new node 100b And host node 100a is also sent to for identical purpose (reference numeral 917 of Fig. 9).It in one embodiment, can be with The communication interface 103a operated with lower frequency is used to send the information to ensure reliably to exchange.However, in another implementation In example, this information can be sent using the antenna array 101a for being operated in higher frequency, because of gt≥γth.If from node 100b still generates g to the use of the beam direction sexual norm of optimizationt＜ γth, then the wave can still be used from node 100b Beam directional mode rises data and optimal beam directional mode information with position/displacement information one from node 100b It is sent to host node 100a (reference numeral 915 and 919 of Fig. 9).In this case, due to gt＜ γth, so BF information is preferred Ground is sent using the communication interface 103a for being operated in lower frequency.It in one embodiment, can be in void value gtSituation Lower transmission BF information can include predefined value, for example, " 0 ", for such case.
In one embodiment, when the MR2 stages start, host node 100a receives data and BF letters from from node 100b Breath, such as position/displacement information of optimal beam direction sexual norm and node 100b.
