For convenience of description, following embodiments using TRP as send equipment, using user equipment as receiving device exemplified by carry out
Explanation.
Wireless network can cover multiple cells (cell), and different districts cover different scopes, and a cell can be used
Network is accessed in user equipment.Each corresponding unique cell ID of cell.Can be including one or several in one cell
Individual TRP.Each TRP includes N number of antenna, and N is the integer more than or equal to 1.Antenna on TRP can carry out wave beam forming, under
Row signal is sent after wave beam forming on antenna.Each wave beam provides wide covering or narrow covering, depending on antenna amount
And beamforming approach.
In the embodiment of the present invention, cell available system information area (the System Information in wireless network
Area) substitute.One cell or system information area are defined as a Radio Network object.In following examples, not special
In the case of statement, " cell " is used to be described, it should be appreciated that " cell " in the embodiment of the present invention can be replaced above-mentioned
" Radio Network object " of definition, such as " system information area ".
Fig. 1 schematically illustrates the network architecture that the embodiment of the present invention is applicable.Wherein, cell 1 includes one
TRP, the TRP send one wide covering wave beam to cover the scope of the cell；Cell 2 includes a TRP, and the TRP sends two
Individual narrow covering wave beam (wave beam 1 and wave beam 2 in figure shown in cell 2) is to cover the scope of the cell；Cell 3 includes two
TRP, each TRP send one narrow covering wave beam, the two narrow covering wave beam (ripple in figure shown in cell 3 that two TRP are sent
Beam 1 and wave beam 2) scope of the cell can be covered.
TRP in above-mentioned wireless network sends access signal, and user equipment can carry out net based on the access signal received
Network accesses.In the embodiment of the present invention, AS (Access will be referred to as the access signal that network insertion is carried out for user equipment
Signal)。
It is to be noted that.AS in the embodiment of the present invention is used for wide in range reference user equipment in access network process
One or several signals that may be used, it is the general designation of the signal needed for user equipment access network process.AS can be with
Including a signal, multiple signals can also be included.One AS can be to realize one or more function, its work(provided
It may can include without being defined in：Initial synchronisation (such as cell synchronous, time domain/frequency domain synchronization), cell (or system information area
Domain) ID detection, system information demodulation etc..Correspondingly, the signal included in an AS can be realized in the above-mentioned function of enumerating
It is one or more.In the embodiment of the present invention, the function that AS is provided can include some in above-mentioned these functions of enumerating or some
Function, but be not limited to it is above-mentioned enumerate these functions, meanwhile, the signal included in an AS is also not limited to realize above-mentioned
The specific signal of some or some functions enumerated.
Existing communication system is concentrated mainly on low-frequency range deployment.With the development of the communication technology, future communication systems meeting
Disposed in 0.4GHz -100GHz big bandwidth range.Below 6GHz low-frequency ranges and more than 6GHz high bands are due to its biography
Performance difference is broadcast, the path loss of high frequency band is much higher relative to low-frequency range, such as, propagation distance is identical, under line of sight conditions,
26GHz carrier frequency is higher 20dB than 2.6GHz carrier frequency path losses.In EIRP (Effective Isotropic
Radiated Power, EIRP) under the same conditions, the coverage of high frequency band signal strongly reduces.
In order to strengthen the network coverage, in the embodiment of the present invention, send equipment and send one or more AS, the AS can when
Repeat to send on domain.
Wherein, an AS can make one or more user equipment access cell or carry out cell identification.One user
Equipment may be based on one or more AS access cells or carry out cell identification.
Wherein, an AS can be sent by a TRP, can also be sent by one group of TRP.One out of a cell
From the perspective of TRP, the TRP can send an AS, and the AS sent is different from the AS that other TRP are sent in the cell；Or
Person, an AS can be transmitted in the TRP, and the AS sent is identical with the AS that at least one other TRP in the cell is sent；Or
Multiple AS can be transmitted in the TRP.
Alternatively, the quantity of the AS transmitted by a cell can be related to many factors.For example, a TRP hair
The AS sent quantity, it is related to the number of beams that the TRP is used, such as, what the AS quantity that a TRP is sent used with the TRP
Number of beams is equal.Again for example, the quantity for the AS that all TRP in a cell are sent, the number with the TRP in the cell
Amount is related, such as, the TRP of the AS that a cell is sent quantity with being included in cell quantity is identical.Again for example, one
The quantity for the AS that all TRP in individual cell are sent, the numbers of beams used with the quantity of the TRP in the cell and each TRP
Amount is related.
As an example, an AS is sent comprising N number of (N is the integer more than 1) TRP, each TRP in a cell,
Then N number of AS can be transmitted in the cell.Each TRP sends AS using broad beam figuration mode, and wave beam can cover used in the TRP
The coverage of the TRP.So, N number of AS of the cell can cover all TRP of whole cell coverage.
As another example, a TRP is included in a cell, the TRP uses M (M is the integer more than 1) wave beams
M AS is sent, each AS is transmitted using a wave beam, and each one direction of beam position, this M wave beam can cover this
The coverage of whole cell.
If a TRP in a cell or cell sends multiple AS, different AS in different transmitted over resources,
That is, this multiple AS can be multiplexed using one or more multiplex modes.Multiple AS are multiplexed in different ways, are made
Different AS can be distinguished by obtaining user equipment.
Wherein, multiplex mode used by different AS, it may include one or more combinations in following multiplex mode：
It is time-multiplexed (Time Division Multiplexing, abbreviation TDM)：Different AS or different AS are at least
One part, sent in different time resources；
Frequency division multiplexing (Frequency Division Multiplexing, abbreviation FDM)：Different AS or different AS
At least one part, sent in different frequency resource；
Space division multiplexing (Space Division Multiplexing, abbreviation SDM)：Different AS or different AS are extremely
A few part, in different space resources, sent using different wave beams, or sent by different TRP；
Code division multiplexing (Code Division Multiplexing, abbreviation CDM)：Different AS or different AS are at least
One part, sent using different sequences, sequence here can include transmission sequence (such as basic codeword sequence
(base sequence)), one or more combinations in scrambler sequence (scrambling sequence) and frequency expansion sequence etc..
As it was previously stated, AS can repeat to send in time domain.Repetition sending methods of the AS in time domain can have it is a variety of, than
Such as, AS repeats to send on adjacent or non-adjacent symbol, wherein, these adjacent or non-adjacent symbols can be in same subframe
In different subframes.AS can also repeat to send in adjacent or non-adjacent subframe.Certainly above two mode can also be combined.
Repetition sending methods of the AS in time domain can be arranged by system, or be determined by transmission equipment, weights of the AS in time domain
Multiple sending method can keep constant, can also be changed as needed.
Fig. 2 is shown in N number of adjacent OFDM (Orthogonal Frequency Division
Multiplexing, abbreviation OFDM) repeat on symbol to send AS example (N is the integer more than 1).As shown in Fig. 2 in figure
Repeat to send AS in N number of adjacent OFDM symbol of oblique line filling.
When it is implemented, AS can be sent on N number of adjacent symbol in following subframe：Subframe n, subframe n+x, subframe n+
2x ... ..., by that analogy.Wherein, " n, n+x, n+2x ... ..., " represents subframe number, and x is integer more than 1, x maximum
For the OFDM symbol quantity included in a subframe.For example in numbering it is OFDM symbol 0 in the subframe of odd number to OFDM symbol
AS is sent on 3, in this example embodiment, if using a 10ms radio frames as the AS transmission cycle, it is each to send AS in the cycle
Number of repetition be 20 (AS sends in 5 subframes and sent on 4 symbols in each subframe)；If by 2 subframes
Transmission cycle of the length as AS, the then number of repetition for each sending AS in the cycle are 4 (in first subframe in 2 subframes
4 symbols on send).In above-mentioned example, AS repeats to send on continuous 4 symbols, therefore it is 1 to repeat transmission time interval
The time span of individual symbol.In other example, above-mentioned N number of continuous OFDM symbol may be alternatively located in multiple subframes, such as, N
When=4,4 adjacent OFDM symbols are：Preceding 2 OFDM symbols of last 2 OFDM symbols and subframe 1 of subframe 0.
In other examples, can also be accorded with k-th of OFDM in N number of 1ms subframes in a 10ms radio frames
Transmission AS example (N is the integer more than 1) is repeated on number, this N number of subframe can be adjacent also non-conterminous.Fig. 3, which is shown, works as N=
2, k=1 situation, i.e., repeat to send AS every a subframe.As shown in figure 3, the 1st in N number of subframe shown in the figure
Repeat to send AS in OFDM symbol (figure bend fill part represents to send AS symbol).In other example, for sending out
The subframe for sending AS can also be N number of subframe adjacent in a radio frames.
Alternatively, the AS repeated in time domain in the position of frequency domain is identical.
Alternatively, AS repetition sending method (such as AS repeat transmission time interval, AS send the cycle, AS one hair
Send the one or more in the parameters such as the repetition transmission times in the cycle) it can make an appointment, it can also be pre-configured with to user
Equipment.For example AS sends the repetition transmission times in the cycle at one and can made an appointment, and can also be pre-configured with and be set to user
It is standby.Alternatively, the AS transmission cycle can be by transmission device configuration.Alternatively, the AS repetition within a repetition period is sent
Number can be by transmission device configuration.
By above description as can be seen that in the above embodiment of the present invention, send equipment and send one or more accesses
Signal, the access signal repeats to send in time domain, so as to strengthen the network coverage.
Referring to Fig. 4, for the schematic flow sheet provided in an embodiment of the present invention for receiving access signal, the flow can be set in reception
Standby side (such as user equipment side) performs.As illustrated, the flow may include following steps：
Step 401：Receiving device reception signal.
In the step, receiving device reception signal and can be sampled on target frequency.Wherein, the target frequency can
To be the frequency where AS.If receiving device can not obtain the frequency where AS, can be searched according to what the receiving device was set
Rope frequency carries out signal search.For example, if AS is sent in the center frequency point position of system bandwidth, UE is when being initially accessed
Centre frequency is not aware that, therefore can only be with 100KHz or the raster search centre frequency of fixed size.
Sample rate can determine according to system bandwidth or using fixed sample rate used by receiving device.For example, UE
System bandwidth is not aware that when being initially accessed, can only be sampled according to the bandwidth of setting, such as according to possible system
Maximum or minimum system bandwidth determines sample rate during regiment commander is wide.
Step 402：Receiving device is filtered according to the bandwidth and frequency of access signal to the signal received.
In the step, bandpass filtering tolerance reception signal can be used to be filtered for receiving device, to retain frequency where AS
Rate, filter out other unnecessary signals.In step 401, time-domain signal is obtained after receiving device samples to reception signal,
But AS generally only takes up a part of bandwidth, therefore is filtered using bandpass filter, the letter where AS can be retained in frequency band
Number, eliminate the influence that other frequency signals are brought.The frequency band of this bandpass filter can be near center frequency point, can also phase
There is certain deviation for center frequency point, this depends on AS frequency locations.For example, the bandpass filter only retains distance center frequency
Signal near point 180kHz.
Alternatively, bandwidth of the width of bandpass filter not less than an AS.
Step 403：Receiving device carries out time domain merging to filtered reception signal.
In the step, receiving device can each setting moment with the first duration by current time and its before common K
Reception signal carries out time domain merging.Wherein, first when a length of receiving device reception signal merge time interval, K be non-zero it is whole
Number.Correspondingly, in step 404, the reception signal that receiving device merges to obtain for each setting moment respectively is accessed
Signal detection.
Wherein, the value of the first duration and/or K value, can be set by receiving device, can also be by transmission device configuration
To receiving device, can also be arranged by system.
Alternatively, the first duration can be that receiving device is based on access signal repetition transmission time interval or access signal weight
What the candidate collection of multiple transmission time interval determined.Wherein, access signal and repeat transmission time interval or access signal repetition hair
Sending the candidate collection of time interval can make an appointment, or prenotice receiving device by transmission equipment.
Alternatively, the first duration can have one of following characteristic：
First duration is equal to access signal and repeats transmission time interval；For example, using shown in Fig. 2 AS repeat sending method as
Example, in the case of sending AS on preceding 4 symbols in numbering the subframe for being odd number, the first duration is equal to the duration of 1 symbol；
First duration repeats transmission time interval with access signal has the relation of integral multiple, i.e. the first duration, which is equal to, to be connect
Enter the integral multiple that signal repeats transmission time interval, or repeat the integral multiple that transmission time interval is equal to the first duration；
First duration has whole with the maximum in the candidate collection of access signal repetition transmission time interval or minimum value
The relation of several times.
Alternatively, above-mentioned reception signal quantity K value can be that receiving device is based on weight in the access signal transmission cycle
Recur the number sent or access in the signal transmission cycle candidate collection determination for the number for repeating to send.Wherein, signal is accessed
It is pre- appoint to send the candidate collection that the number of repetition transmission or access signal send the number of repetition transmission in the cycle in the cycle
It is fixed or receiving device is prenoticed by transmission equipment.
Alternatively, K value can have one of following characteristic：
K is equal to the number that access signal repeats to send within the repetition period；For example, sender is repeated with the AS shown in Fig. 2
Exemplified by formula, in the case of sending AS on preceding 4 symbols in the subframe that numbering is odd number, K=4；
The number that K repeats to send with access signal within the repetition period has the relation of integral multiple, i.e. K, which is equal to access, to be believed
The integral multiple of number sent is repeated number within the repetition period, or the number that access signal repeats to send within the repetition period is equal to
N integral multiple；
The maximum or minimum value of K and the candidate collection of access signal repetition transmission time interval have the pass of integral multiple
System, wherein, the possibility number that access signal repeats to send within the repetition period provides or sent equipment notice reception by agreement and sets
It is standby.
Merged when it is implemented, one or more delayers can be used to choose the signal received at different moments.Prolong
The time delay of slow device can be equal to AS repetition transmission time interval, and the M of repetition transmission time interval that also can be equal to AS/
One, M are the integer more than 1, i.e. the repetition transmission time interval of AS is M times of the time delay length of delayer, to ensure to prolong
Slow device can choose the signal for sending AS.The number of repetition that the number of delayer can be equal to AS subtracts 1, might be less that AS weight
Again number subtracts 1, and the number of signals now merged is less than M, and number of repetition that can also be more than AS subtracts 1, in the signal now merged
Other signals may be mixed into.
So that the AS shown in Fig. 2 repeats sending method as an example, AS is sent on preceding 4 symbols in the subframe that numbering is odd number
In the case of, as shown in figure 5,3 delayers can be set, the time delay length of each delayer is grown for the time of 1 symbol
Degree.
So that the AS shown in Fig. 3 repeats sending method as an example, as shown in fig. 6,1 delayer can be set, each delayer
Time delay length is the time span of 2 subframes.
Step 404：Reception signal after receiving device merges according to time domain carries out access signal detection.
In the step, the reception signal progress after receiving device can be merged using local sequence and time domain is related, during acquisition
The peak value of reception signal after the merging of domain, AS is judged whether according to the peak value.As an example, UE can utilize local sequence
The reception signal progress arranged after merging to time domain is related, and peak value is found by peakvalue's checking, if peak value is more than certain thresholding,
Think that AS is present.
For example, the time-domain signal after bandpass filtering is expressed as r (0), r (1) ..., r (n) ..., each OFDM symbols
Number there is L sampled point, then the signal after time domain merges is expressed as：
UE is related to y (t) by local sequence, finds the peak value in y (t), if the position of peak value is t0, then UE can compare
The correlation size of relatively following 2K-1 position, the peak for selecting the maximum position of correlation to determine：
t0-L(K-1),t0-L(K-2),...,t0-L,t0,t0+L,...,t0+L(K-2),t0+L(K-1)
Alternatively, receiving device can utilize local sequence to detect multiple AS from the reception signal after time domain merging.
Alternatively, receiving device also obtains synchronizing information while AS is detected using peak value.Ideally, peak
, can according to peak value at the time of value corresponds to last transmission AS (because the merging signal at the moment corresponds to the AS of all transmissions)
To obtain the timing information that last time sends AS symbol.But in actual conditions, user equipment possibly can not receive all
The AS sent, or the influence due to noise are repeated, the not corresponding last time of the peak value that user equipment detects sends AS's
The timing information of symbol.It now can aid in obtaining the timing information of symbol based on other signals.
In the embodiment of the present invention, a kind of possible method is：Another signal is being sent corresponding to AS on symbol, the signal
With timing reference function, receiving device can combine AS detections and the signal is realized synchronously.Here, it is referred to as timing reference
Signal.Certainly, the signal can be also named with other titles, and further, the signal can have other functions, the application
Embodiment is not limited.
Correspondingly, the reception signal after receiving device merges according to time domain, during obtaining synchronizing information, it can detect and work as
