Technical field

Background technology

In traditional LTE (Long Term Evolution, Long Term Evolution) access technology, the transmission in base station meeting cycle is same Walk signal, including master sync signal and auxiliary synchronous signals and PBCH (Physical Broadcast Channel, physical broadcast Channel).UE (User Equipment, user terminal) after powering, it is synchronous and small to obtain to detect synchronizing signal first Area ID (mark), PBCH is then detected again to obtain system broadcast message.PBCH is to rely on CRS (Cell Specific Reference Signals, cell own reference signal) come what is demodulated.Because synchronizing signal and PBCH are cell-specifics, All user terminals be able to will detect in cell, so synchronizing signal, PBCH and CRS can substantially cover whole cell. That is general base station when sending these cell-level signals is a very wide wave beam to reach cell-level covering.Such as Shown in Fig. 1.Because LTE carrier frequency is substantially below 6GHz, the broad beam formed using multiple antennas can be covered Cover whole cell.Such as in LTE, master sync signal and auxiliary synchronous signals were sent with the 5ms cycles, in each cycle Interior, base station is utilized respectively a time domain OFDM (Orthogonal Frequency Division Multiplexing, orthogonal frequency Point multiplexing) symbol (6 PRB (Physical Resource Block, Physical Resource Block) on frequency domain) sends master sync signal And auxiliary synchronous signals, wherein the wave beam used in each symbol is the broad beam that can cover whole cell.

And in 5G (the 5th third-generation mobile communication technology), below 6GHz carrier wave frequency range is not only supported, also to be supported More than 6GHz frequency range, such as 60GHz.Due to very big in high band large scale path loss, this brings to radio communication Very big challenge.But due to high in high band centre frequency, wavelength is short, the open ended antenna amount in base station is many and utilizes Multiple antennas form very narrow wave beam to form beam shaping gain, thus narrow beam excipient almost strengthen into high band it is small The essential technology of area's covering.

However, for foregoing cell-level signal, such as synchronizing signal, in order to cover whole cell, base station must be used Many narrow beams repeat to send these cell-level signals in a different direction, as shown in Figure 2.Traditional method is by one All time-domain symbols all send cell-level signal using narrow beam in individual subframe, such as shown in Fig. 3, wherein each time-domain symbol For sending one or more of PBCH, synchronizing signal, beam reference signal by narrow beam, different time-domain symbols is corresponding Different narrow beams.In this way, base station effectively can send different narrow beams to cover whole cell, ripple by poll to profit When beam is more, the wave beam transmission cycle can increase, i.e., the wave beam in different subframes can be different.But this method is for low Frequency range compatibility is poor because the wave beam that low-frequency range is formed is wider, when required number of beams is seldom, this method due to All the time whole subframe is reserved to these cell-level signals, can cause unnecessary waste.

Embodiment

For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with accompanying drawing to the present invention Embodiment be described in detail.It should be noted that in the case where not conflicting, in the embodiment and embodiment in the application Feature can mutually be combined.

Can be in the computer system of such as one group computer executable instructions the flow of accompanying drawing illustrates the step of Perform.Also, although logical order is shown in flow charts, in some cases, can be with suitable different from herein Sequence performs shown or described step.

The embodiment of the present invention proposes a kind of signaling method, can be, but not limited to be used to send cell-level signal；It is described Signaling method as shown in figure 4, including step 100~110：

100th, the first communication node determines M signal；

110th, first communication node sends the M signal on predefined N number of time-domain symbol unit, according to institute The mapping ruler between N number of time domain unit and wave beam unit is stated, it is determined that carrying the sequence number of the wave beam unit of the M signal；Its In, M and N are positive integer, and M is less than or equal to N.

The equipment that wherein the first communication node also refers to base station or similar base station, believes available for physical broadcast is sent The cell-level signal such as road, synchronizing signal.

Alternatively, M described signal includes Physical Broadcast Channel, synchronizing signal, for measuring RRM The reference signal of (Radio Resource Management, RRM), or for measuring the reference signal of wave beam and being used for Demodulate one or more in the cell-level signals such as the reference signal of broadcast channel.Broadcast channel herein can refer to carrying The channel of system parameter message, can be otherwise varied with the broadcast channel in LTE, but acts on similar.

Alternatively, the time domain unit is time-domain symbol (time-domain symbol i.e. in physical concept), or, time-domain symbol group； One time-domain symbol group includes one or more time-domain symbols；

The wave beam unit is wave beam, or, wave beam group；One wave beam group includes one or more wave beams.

Alternatively, corresponding to M signal it is M wave beam unit.

Wherein, N number of time domain unit can provide in advance, that is to say, that N value can not need base station to use Signal.One time domain unit can include the time-domain symbol in one or several physical concepts.For example, in LTE Or in other systems, a subframe has the time-domain symbol in 14 physical concepts, if a time domain unit is one Including the time-domain symbol group of 2 physical time domain symbols, then the subframe can have up to 7 predefined time domain units, That is subframe N=7.And if a time domain unit includes the time-domain symbol in 1 physical concept, then the subframe is most Can there are 14 predefined time domain units, i.e. subframe N=14.Time-domain symbol in physical concept mentioned here can To regard the OFDM time-domain symbols actually included in a subframe as.

The situation comprising a time-domain symbol can have two kinds in one time domain unit：In a kind of situation, time domain unit is Refer to time-domain symbol；In another situation, time domain unit refers to time-domain symbol group, is accorded with a time-domain symbol group comprising a time domain Number.

When time domain unit refers to include multiple time-domain symbols in time-domain symbol group and a time-domain symbol group, at one Multiple time-domain symbols can be included in the unit of domain.

Alternatively, corresponding to the M signal it is M wave beam group.The corresponding time-domain symbol group of one wave beam group, and Carry one or more in above-mentioned cell-level signal.That is, for sending broadcast channel, synchronizing signal or wave beam One wave beam group of these cell-level signals such as reference signal can take one or several time-domain symbols.In a subframe, Predefined N number of time-domain symbol group can be a part of time domain symbol in the whole time-domain symbols or subframe of the subframe Number.

One wave beam group can include P wave beam, P value can by broadcast channel in cell-level signal it is explicit or it is hidden What is contained is indicated to UE.That is, the broadcast channel that as long as UE correctly detects certain wave beam or wave beam group carries, it is possible to obtain P value.

Alternatively, can be different for different first communication nodes, the mapping ruler, can also be identical.

For example, Z is equal to 1, the sequence number of the wave beam unit of the M signal is carried, from last in the n time domain unit 1 time domain unit is numbered.Or Z is equal to 2, the sequence number of the wave beam unit of the M signal is carried, from N number of time domain Penultimate time domain unit in unit is numbered, and is recycled to last time domain unit, such as first time domain list The serial number #12 of wave beam unit corresponding to member, then wave beam unit corresponding to last time domain unit serial number #13.

During situation, i.e. M=N when this alternative goes for M=N or M ＜ N, or during M ＜ N, can use from The mode that the Z time domain unit reciprocal is numbered determines the sequence number of wave beam unit.

In this alternative, it can determine to send the time domain unit of the M signal by Z value when described N number of Position in the unit of domain；Such as Z=1, the time domain unit that sends the M signal be in N number of time domain unit most M time domain unit afterwards；For example as Z=2, the time domain unit that sends the M signal is reciprocal the in N number of time domain unit 2 time domain units, and M-1 time domain unit before the time domain unit.

In this alternative, the wave beam unit corresponding to the Z time domain unit reciprocal since N number of time domain unit Numbering can include：

Wherein, the direction reduced toward the time, it is that one kind is fallen that the wave beam unit corresponding to time domain unit, which is sequentially numbered, The mode of sequence numbering, that is to say, that the sequence number difference 1 of wave beam unit corresponding to adjacent time domain unit, and time-domain position is preceding The sequence number of wave beam corresponding to time domain unit, more than the sequence number of wave beam corresponding to the time domain unit of time-domain position rearward.

In this alternative, serial number can also be carried out, i.e.,：The Z time domain unit institute reciprocal from N number of time domain unit Corresponding wave beam unit starts, and toward the direction of time increase, the wave beam unit corresponding to time domain unit is sequentially numbered, That is the sequence number difference 1 of wave beam unit corresponding to adjacent time domain unit, and ripple corresponding to the preceding time domain unit of time-domain position The sequence number of beam, less than the sequence number of wave beam corresponding to the time domain unit of time-domain position rearward.In this alternative, for different institutes The first communication node is stated, Z value can be different, and used time-domain resource at least can part mistake between such different districts Open.Furthermore it is possible to which the communication node of part first uses serial number mode, the communication node of part first uses inverted order numbering side Formula.

In above two alternative, the mapping ruler such as serial number or inverted order numbering can be used, to determine wave beam The sequence number of unit.

In other alternatives, first communication node can also use M of foremost in N number of time domain unit Time domain unit sends the M signal.

In above two alternative, methods described can also include：

Alternatively, the mapping ruler described in this embodiment scheme can be according to physical district ID and/or systematic parameter Determine.Mapping ruler corresponding to different districts ID and/or systematic parameter can be different.UE determine cell ID and/or The mapping ruler of current time unit can be learnt after person's systematic parameter, so as to learn the sequence number of detected optimum beam.Its Middle systematic parameter may include System Frame Number, subframe numbers etc..So mapping ruler corresponding to different subframes can be different.Cell ID and/or systematic parameter can be learnt from the synchronizing signal entrained by the wave beam detected, broadcast channel.For example, UE can be from Cell ID, system subframe number are detected in synchronizing signal, and System Frame Number is learnt from broadcast channel.The mapping ruler also may be used To be pre-defined or give tacit consent to.

The embodiment of the present invention also provides a kind of signal acceptance method, can apply in UE sides, as shown in figure 5, including step 200~210：

200th, the second communication node receives M signal on predefined N number of time domain unit, wherein, M and N are positive integer, M is less than or equal to N；

210th, second communication unit is according to the mapping ruler between N number of time domain unit and wave beam unit, it is determined that Carry the sequence number of the wave beam unit of the M signal.

Wherein, be numbered can be with for the wave beam unit corresponding to the Z time domain unit reciprocal from N number of time domain unit Including：

Wave beam unit since N number of time domain unit corresponding to the Z time domain unit reciprocal, toward the side of time reduction To the wave beam unit corresponding to time domain unit is sequentially numbered.Alternatively, second communication node is in predefined N M signal is received on individual time domain unit to be included：

Alternatively, methods described also includes：

When M is less than N, second communication node is in N number of time domain unit, the carrying M time domain unit it On outer time domain unit, the control signaling sent from the first communication node, data, channel measurement reference signal, data solution are received One or more in reference signal is adjusted, or sends ACK/NACK, channel measurement reference signal, channel information measurement result In one or more.

Illustrate the signaling method and signal acceptance method of the embodiment of the present invention, including step 1 with an example below ~five；In the example, using time-domain symbol group as time domain unit, wave beam unit is used as using wave beam group；First communication unit is base Stand, the second communication unit is UE.

Step 1

UE is before non-access system, it may be necessary to the position of each predefined wave beam of measurement to demodulate broadcast channel, or Person's synchronizing signal, or beam reference signal etc..That is, base station may need to detect N number of predefined wave beam (or ripple Beam group) shared by time-domain symbol group obtain these cell-level system informations.These cell level knowledges can include systematic parameter, Such as System Frame Number, subframe numbers, cell ID etc..Same wave beam group takes identical time-domain symbol group.Same time-domain symbol Different time-domain symbols can correspond to different cell-level signals in group, can also correspond to identical cell-level signal.

Step 2

And in fact, base station is according to the situation of reality, such as carrier frequency end, antenna for base station is how much, and cell scenario etc. is come Send these cell-level signals.The wave beam group number that real base station needs may be smaller than predefined wave beam group number, so Base station actual capabilities send wave beam in some time-domain symbol groups in predefined time-domain symbol group.That is, base Station may not be needed to send cell-level signal in predefined all time-domain symbol groups.

In addition, the wave beam number M*P that the broadcast channel that each wave beam group carries may send base station, or send M The number M of the time-domain symbol group of individual signal and every group of wave beam number P included are notified to UE.Certainly, base station is actual sends Wave beam number or time-domain symbol group number can also be sent to UE after UE access systems by high-level signaling.

If the time-domain symbol group number that base station is sent shared by the wave beam group of cell-level signal is fewer, the subframe also has Remaining resource, base station can send other signals in the remaining resource of the subframe.That is, when M is less than N, the base station can Can in N number of time-domain symbol group, send transmission descending control signaling in resource beyond the M signal used resource, One or more in data, the signal such as channel measurement reference signal, data demodulation reference signal, or receive and sent from UE ACK/NACK, channel measurement reference signal, one or more in the feedback signal such as channel information measurement result.

For another example when M is less than N, the UE may receive the M letter of repetition in N number of time-domain symbol group One or more in number.I.e. base station can be in the wave beam group that the repetition of remaining resource has been transmitted across.

For another example for the different base stations, the corresponding pass between the sequence number of wave beam unit and the sequence number of time domain unit System can be different.Base station can not send any signal in remaining resource.Now, the sequence side of the wave beam group of different districts Method can be caused the actual time-domain symbol group difference for sending beam signal and taking in different districts, can so be reduced with different Inter-cell interference.

This step can not consider the sequence number of wave beam group.That is, even if the wave beam group of M signal of carrying is without sequence Number, remaining resource still can be used for sending other signals.

Step 3

The UE of non-access system will detect that one most by detecting cell-level signal in predefined time-domain symbol group Good wave beam group or wave beam, while cell ID, synchronizing signal, broadcast channel etc. can be obtained.If base is included in broadcast channel Stand and send the number of wave beam, or the wave beam number that the number comprising time-domain symbol group and each wave beam group include, then UE can With according to wave beam sortord (such as：Order or inverted order) and the wave beam number of base station transmission obtain the sequence number of optimum beam.

Step 4

For the UE of access system, it may be necessary to configured according to high-level signaling, or the subframe is actual when can be remaining The number of domain set of symbols judges, if in predefined N number of time-domain symbol group except shared by M cell-level signal when Other signals are detected outside the set of symbols of domain.For example, by detecting broadcast channel, learn that the subframe there remains greatly in addition to cell-level signal When the time-domain symbol group of L, UE needs detect control channel and corresponding schedule information, wherein L in the subframe to be The configuration of predefined or high-level signaling.Or UE can know whether examine in the subframe by high-level signaling Survey control channel and corresponding schedule information.Certainly, UE is also required to be judged whether according to schedule information or high-rise configuration Need in remaining last either feeding back ACK/NACK or channel measurement information in several time-domain symbol groups.

UE for waiting accidental access response, it is also possible to send subframe detection Stochastic accessing in cell-level signal and ring Should.Or regulation, UE need not detect accidental access response in this subframe.

Step 5

UE notifies the sequence number of base station best one or multiple wave beam groups by explicit either implicit feedback system. For example, can by Stochastic accessing ascending resource position corresponding to different RACHs, come notify base station one or The sequence number of several best wave beam groups.

Below signaling method and signal acceptance method provided in an embodiment of the present invention are illustrated with 5 embodiments. In this 5 embodiments, using time-domain symbol group as time domain unit, wave beam unit is used as using wave beam group；First communication unit is base Stand, the second communication unit is UE.

Embodiment 1

One wave beam group broadcast channel correspondingly to be sent, beam reference signal, synchronizing signal etc. occupy a time domain Symbol.One transmission unit is exactly a subframe, contains 14 time-domain symbols.

The number of predefined wave beam is 14 in a subframe.That is before not accessing, UE may need to examine Survey in the subframe each wave beam in wave beam group, and wave beam group corresponding to predefined all time-domain symbol groups.Pass through detection The optimum beam group that arrives can detect correct wave beam group, and UE can obtain the information entrained by cell-level signal.

In the present embodiment, a wave beam is included in a wave beam group, a time-domain symbol group includes a time-domain symbol, It is 14 that one cell-level signal, which sends time-domain symbol in subframe, and predefined wave beam group and time-domain symbol group number is also 14 It is individual, i.e. N=14 in a subframe.UE is before non-access system, it may be necessary to is detected in each cell-level signal subframe all Predefined time-domain symbol, until detecting optimum beam.Now, UE assumes each predefined wave beam or time-domain symbol It is possible to be sent.The different direction of different beam positions, so different UE may detect different wave beams.But In same subframe, the broadcast channel entrained by different beams is probably the same.The period of sub-frame of cell-level signal can be It is predefined, such as the cycle is X subframe.So these cell-level signals can be sent in subframe #0, subframe #X, subframe # 2X..。

Among reality, base station can determine the number of wave beam according to different situations.Such as in high band, antenna element ratio More, the wave beam typed it out is narrow, if to cover whole cell, it is necessary to wave beam number can be a lot.In this case, The transmission cycle of wave beam can lengthen, and base station can send different wave beams in each time-domain symbol of cell-level signal subframe, no Can also be different with wave beam corresponding to time-domain symbol in subframe.If it is 2 subframes that wave beam, which sends the cycle, each symbol corresponding one Individual wave beam group, if a wave beam group corresponds to a wave beam, in two subframes, 28 time-domain symbols can be used for sending 28 Different wave beams.The transmission cycle of wave beam can by detect broadcast channel it is explicit or implicit learn.

It is a subframe that if wave beam, which sends the cycle, it is believed that predefined is 14 time-domain symbol groups, i.e. N is equal to 14, The wave beam group number that base station is sent within a wave beam transmission cycle is not more than 14.And if it is two sons that wave beam, which sends the cycle, Frame, it is believed that predefined is 28 time-domain symbol groups, i.e. N is equal to 28, and base station sends what is sent in the cycle in a wave beam Wave beam group number is not over 28, naturally it is also possible to thinks in a subframe, predefined time-domain symbol group number is 14, and The wave beam group number that base station is sent in this subframe is not over 14.

If in low-frequency range, a period of time of antenna is fewer, and the wave beam typed it out is very wide, such as a wave beam can covering Whole cell.Now base station can only send a wave beam to carry these cell-level signals when actually sending.That is, Also remaining 13 time-domain symbols are not used for sending wave beam.

In this example, the broadcast channel that each wave beam group carries contains the wave beam group number of base station transmission.

When base station sends these cell-level signals, base station utilizes the spy in N number of predefined time-domain symbol group as far as possible Determine part.If the wave beam group required for actual transmission is seldom, base station takes possibly also with except M cell-level signal beam group Time-domain symbol outside remainder send other signals.I.e. when M is less than N, first communication node N number of time domain Last M time-domain symbol in symbol sends the M signal.For example, base station can utilize one send subframe in last A little time-domain symbols send these cell-level signals.Such as Fig. 6-a, base station actually only have sent a wave beam, and send son The wave beam is sent in last time-domain symbol (i.e. time-domain symbol #13) of frame.And in Fig. 7-a, 7-b, base station is actual to have sent 2 Individual wave beam and it is placed in last 2 time-domain symbols of the subframe, for example is to use time-domain symbol #12 send waves in Fig. 7-a Beam #0, time-domain symbol #13 send wave beam #1；It is that wave beam #13 is sent using time-domain symbol #0, using time-domain symbol # in Fig. 7-b 12 send wave beam #1, and time-domain symbol #13 sends wave beam #0.

Now, first communication node may send descending control signaling, data, letter in N number of time-domain symbol One or more in road measuring reference signals, data demodulation reference signal, or receive what is sent from the second communication node One or more in ACK/NACK, channel measurement reference signal, channel information measurement result.I.e. base station can utilize each Send at most preceding 13 time-domain symbols (corresponding diagram 6-a) or at most preceding 12 time-domain symbols (corresponding diagram 7-a, 7-b) in subframe Send down control channel, descending or upstream data information and reference signal etc..Certainly, send outside M signal remain In remaining time-domain symbol, last or several time-domain symbols can keep for the UE accessed to send ACK/NACK, SRS etc.. Wherein the second communication node refers to UE.

A kind of mode of wave beam sequence, carry the M signal wave beam unit sequence number from N number of time-domain symbol or Z time-domain symbol or time-domain symbol group reciprocal are numbered in time-domain symbol group.Wherein Z is less than or equal to N positive integer.

As shown in Fig. 7-a, since the sequence number of wave beam be the order sequence backward actually sending the time-domain symbol of wave beam.Figure In 7-a, two send wave beam altogether, and wave beam #0 is sent in time-domain symbol #12, and wave beam #1 is sent in time-domain symbol #13, also It is to say, base station is backward (toward time-domain symbol #13 since the second-to-last time-domain symbol (i.e. time-domain symbol #12) of the subframe Direction) sequence number of wave beam, Z=2 corresponding to order increase.The UE not accessed can at least be examined after predefined wave beam has been detected Corresponding time-domain symbol #12 in best wave beam, such as Fig. 7-a is measured, the broadcast message then carried from this wave beam learns base The wave beam actually sent of standing is 2, and subframe is last, and UE can be extrapolated because all wave beams actually sent are placed on The sequence number of wave beam is #0 corresponding to time-domain symbol #12.

Another sortord such as Fig. 7-b or 10-a, when since last 1 time-domain symbol of the subframe to first Domain symbol, the sequence number of wave beam are inverted orders, Z=1.In Fig. 7-b, wave beam, wave beam # are actually sent in two time-domain symbols altogether 0 is sent in time-domain symbol #13, and wave beam #1 is sent in time-domain symbol #12.UE at least can after predefined wave beam has been detected Corresponding time-domain symbol #12 in best wave beam, such as Fig. 7-b is detected, so UE can be extrapolated corresponding to time-domain symbol #12 The sequence number of wave beam is #1.In Fig. 7-b or 10-a, the cycle that wave beam is sent is a subframe.And if wave beam sends the cycle It is 2 subframes, predefined time-domain symbol group has just reached 14*2=28.If the wave beam group that base station is sent is small more than 14 In 28, wave beam sequence number is as shown in Figure 10-b.After optimum beam is detected, UE can be from optimum beam (or optimum beam group) institute The number for the wave beam that base station is sent, such as 16 are learnt in the broadcast channel of carrying.Now, base station can obtain according to mapping ruler To know, base station sends 14 wave beams before subframe may have sent at first, and in most latter two time-domain symbol of second subframe On have sent 2 wave beams.And remaining 12 time-domain symbols are possibly used for sending other signal before second subframe.Herein In the case of kind, the transmission cycle of wave beam is two subframes, and one sent in the cycle, and wave beam sequence number is accumulative sequence.

After the sequence number and the number of wave beam for obtaining actual wave beam, the UE that does not access can utilize in broadcast channel or The random access resource information that other Channel Detections arrive, the feedback that the sequence number of the wave beam of selection is implied by RACH To base station.Such as base station can distribute to the how individual random access resources of UE by broadcast channel or by predefined mode, one In the individual Stochastic accessing cycle, different random access resources corresponds to the sequence number of different wave beams.Different random connect may be selected in UE Enter resource to indicate the sequence number of base station selected wave beam.

There are the sequence number of two kinds of wave beams and the corresponding relation of random access resource：First, it is forward that small sequence number corresponds to time domain Random access resource, such as Figure 11-a；Second, big sequence number corresponds to the forward random access resource of time domain, such as Figure 11-b.

For the UE of other access systems, if learnt from broadcast channel in the transmission subframe of cell-level signal When the number of remaining time-domain symbol is more than L, these UE cannot assume that this subframe does not spend detection downgoing control signal or data. That is, for this subframe, these UE are it should be assumed that may have data transmission.L can be that high-level signaling is notified and obtained.Or Person, UE directly can know whether that needs continue detection and there may be control signaling, data etc. in the subframe from high-level signaling.

Embodiment 2

Unlike embodiment 1, when M is less than N, first communication node is with N number of time-domain symbol Between M time-domain symbol send the M signal, i.e. base station is utilized in a transmitting element except last or several time domains The remainders of the several time-domain symbols of symbol and foremost sends these cell-level signals.

As shown in Fig. 6-b, base station only have sent a wave beam, be placed on the penultimate time-domain symbol of subframe (immediately Domain symbol #12).In Fig. 6-b, base station can utilize each other time domains symbol sent in subframe in addition to time-domain symbol #12 Number send other signals.For example, with time-domain symbol #0~#11 come send down control channel, downstream data channel or under Row Sounding Reference Signal.Time-domain symbol #13 can be used for the feedback such as receiving channel information, ACK/NACK.In this manner it is achieved that Self-contained subframe structure.That is, UE can feed back the data channel for above time-domain symbol by time-domain symbol #13 And the measurement result of Sounding Reference Signal.

In Fig. 7-c, base station is actual to have sent 2 wave beams, when being placed on the penultimate and third last of subframe Domain symbol, i.e.,：Wave beam #1 is sent using time-domain symbol #11, time-domain symbol #12 sends wave beam #0.Base station can utilize each cell Level sends other symbols in subframe in addition to symbol #11, #12 to send other signals.

A kind of wave beam sortord, such as 2 transmission wave beams in Fig. 7-c, the cycle that wave beam is sent is a subframe, wave beam Sequence number is from the second-to-last sign-on of subframe inverted order forward, Z=2, is recycled to last symbol.Base in Fig. 7-c Reality of standing only have sent wave beam #0, #1.Other mapping methods are also not excluded for.In Fig. 7-c, two reality send wave beam altogether, Wave beam #0 is sent in time-domain symbol #12, and wave beam #1 is sent in time-domain symbol #11.The UE not accessed detected it is predefined After wave beam, corresponding time-domain symbol #11 in best wave beam, such as Fig. 7-a is at least will detect that, is then carried from this wave beam Broadcast channel learns that the actual wave beam sent in base station is 2, and because the sequence number of all wave beams actually sent is from time domain Symbol #12 starts inverted order forward, so the sequence number that UE can extrapolate wave beam corresponding to time-domain symbol #11 is #1.

Embodiment 3

It is described in preceding embodiment, if in low-frequency range, a period of time of antenna is fewer, and the wave beam typed it out is very wide, than As a wave beam can covers whole cell.Now base station can only send a wave beam to carry these when actually sending Cell-level signal.That is, in the case of the corresponding wave beam group of a time-domain symbol group, it is assumed that a time-domain symbol group Comprising a time-domain symbol, then also remaining 13 time-domain symbols are used for sending wave beam.

Unlike Examples 1 and 2, the sortord of different cells beams can be different.Described in different First communication node, the value of the Z can be different.

That is, mapping ruler determines according to cell ID.Such as Fig. 8-a, the sequence numbers of cell #0 wave beams be from when Domain symbol #0 order starts to increase.And in cell #1, the sequence number of wave beam be since time-domain symbol #2 with symbol sequence number and Increase is recycled to time-domain symbol #0 and time-domain symbol #1.

In Fig. 8-a, the number of the actual wave beams sent of cell #0 and #1 is all 2.For cell #0, if UE is detected most Good wave beam can learn the number for the wave beam that reality sends altogether by broadcast channel, due to actual multiple ripples in time-domain symbol #1 Continuously transmitted during beam (predefined), and wave beam is sent since time-domain symbol #0, and such UE can be extrapolated most preferably The sequence number of wave beam is wave beam #1.And for cell #1, if UE detects optimum beam in time-domain symbol #3, due to actual multiple Continuously transmitted during wave beam, and wave beam is sent since time-domain symbol #2, and such UE can extrapolate the sequence of optimum beam Number it is wave beam #1.

In Fig. 8-b, if the number of the wave beam actually sent is 1, then wave beam can be sent in arbitrarily by base station In time-domain symbol.

By the method, if the wave beam group actually sent is less than predefined time-domain symbol group, remaining time-domain symbol Group can be not used to send any signal.The actual wave beam sent in different districts may not be overlapping, and so interfering will Substantially reduce.

And if base station send wave beam number more than 14 or base station send the wave beam cycle be more than 1 subframe, than Such as 2 subframes, wave beam sequence number can be accumulative sequence.Such as Figure 12-a, for cell #0, the sequence of wave beam is from the first subframe To the accumulative superposition of second subframe.And for cell #1, such as Figure 12-b, accorded with when wave beam sorts from the time domain of first subframe Number #2 starts to include the accumulative superposition of symbol of second subframe backward after, the time-domain symbol #0, #1 of first subframe are recycled to.

Directly it can be notified it is worth noting that, wave beam sends the cycle by base station, the wave beam that can also be sent according to base station Number is calculated, such as when a wave beam is included in a wave beam group, if learning that base station have sent 16 wave beams and (be more than 14 And less than 28), UE can learn that the wave beam transmission cycle is 2 subframes.And if containing such as 8 ripples in a wave beam group 14*8 wave beam at most can be transmitted in beam, a subframe, and so because 16 are less than 16*8, UE can learn that the wave beam transmission cycle is one Individual subframe.

Except cell ID, described mapping ruler can also determine according to other systems parameters, such as system subframe Number.For different system subframes number, mapping ruler can be different.Such as the cell #0 for only having two wave beams to be sent, On subframe n1, two wave beams are wave beam #0, and wave beam #1 maps respectively on time-domain symbol #0, #1, and on subframe n2, ripple Beam #0, #1 can then be mapped in time-domain symbol #2, #3.And for cell #1, on subframe n1, two wave beams are wave beam #0, wave beam # 1 maps respectively on time-domain symbol #4, #5, and on subframe n2, wave beam #0, #1 can then be mapped in time-domain symbol #0, #1.

Certainly, if the mapping ruler of wave beam has no relations with cell ID, or also do not become with the difference of systematic parameter Change, then mapping ruler can be predefined or acquiescence, it is not necessary to changes.

Embodiment 4

Unlike embodiment above, base station may remove M time-domain symbol in predefined N number of time-domain symbol group In time-domain symbol group outside group transmission cell-level signal is repeated using the wave beam group being transmitted across.I.e. when M is less than N, institute State the first communication node and repeat to send one or more in the M signal in N number of time-domain symbol

As shown in Figure 9, it is assumed that a wave beam group includes a wave beam, and a time-domain symbol group includes a time-domain symbol, The wave beam number for being actually needed transmission is 12, and in remaining two time-domain symbols, base station repeats to have sent wave beam #0 and #1.

In different transmission subframes, remaining time-domain symbol can be used for repeating to send different wave beams.Such as in son Frame #0, remaining two time-domain symbols are used for sending wave beam #0, #1, and in subframe #X, remaining time-domain symbol is used for send wave Beam #2, #3.

Embodiment 5

In this example, a wave beam group can include multiple wave beams, and launch in identical time-domain symbol.Such as one 8 wave beams are contained in wave beam group.Such a cell-level signal transmitting subframe can at most launch 14 wave beam groups, that is, 14*8 wave beam.One sends the number that wave beam group number and a wave beam group include wave beam in the cycle and can pass through broadcast channel Or the notice that other signals imply is to UE.The sortord of the sequence number of wave beam has two kinds：

Firstth, the sequence number of wave beam first can sort according to time-domain symbol group, then increase again in wave beam group.Such as falling In the example of sequence, if 2 wave beam groups, totally 16 wave beams transmissions, then in Fig. 7-b example, symbol #13 wave beam bag #0 containing wave beam, #2, #4, #8；Wave beam #1, #3, #4, #7 are included in symbol #12.

Secondth, wave beam sequence number first can increase in wave beam group, be sorted according still further to time-domain symbol group.If 2 wave beams Group, totally 16 wave beams transmissions, then in Fig. 7-b example, symbol #13 wave beam includes wave beam #0, #1, #2, #3；Symbol # Wave beam #4, #5, #6, #7 are included in 12.

In addition, a time-domain symbol group may include multiple time-domain symbols, i.e. a wave beam group may correspond to multiple time domains Symbol.In a time-domain symbol group, different time-domain symbols may correspond to different cell-level signals.Such as two time domain symbols Number one wave beam group of correspondence, such a cell-level signal transmitting subframe can at most include 7 wave beam groups.One time-domain symbol In group, what the first symbol carried is synchronizing signal, and second symbol carries broadcast channel.
