Description

Signal sends and device identification method and equipment

Technical field

Sent and device identification method and equipment the present invention relates to wireless communication field, more particularly to a kind of signal.

Background technology

With technology development and the explosive growth of data service, increasing micro-base station (Pico), Home eNodeB Low power base stations such as (Home NodeB) can be collectively referred to as by deployment for providing local small covering, the cell of this kind of base station covering Microcellular（small cell）.Deployment small cell can not only extend macrocell（Macro cell）Covering, also can Handling capacity enough in lifting specific region.Usually, the small cell for being disposed in network are more, then have more users can be with Serviced by small cell, enjoy the performance gain that small cell bring so that network entire throughput obtains bigger Lifting.It is contemplated that in real network, it is likely that appear in a large amount of dense deployments in geographic area of business demand concentration The situation of small cell.

In the prior art, cell is identified using synchronous signal sequence, in Long Term Evolution（Long Term Evolution, LTE）In system, master sync signal is used（Primary Synchronized Signal, PSS）And auxiliary synchronous signals （Secondary Synchronization Signal, SSS）Joint mark cell, system provides 504 and can distinguish mutually altogether Cell ID（ID）, require to use mutually different cell ID between neighbor cell in network design.Only have in traditional Macrocell（Macro only）Or in the cell deployment of Macro cell areas+low-density small cell, be easier to accomplish phase Adjacent cell uses different cell ID.But it is either centralized when a large amount of dense deployment small cell cells are needed Cell ID allocation mode, or distributed cell ID allocation mode, will reach neighbor cell and use different cell ID Requirement, network planning complexity can be caused to improve, or lead to not because cell density is excessive meet in the scene of part As above require, cause to occur obscuring when terminal or Network Recognition cell.

Fig. 1 gives a kind of schematic diagram of deployment small cell a large amount of in Macro networks, wherein Macro cell and Small cell use different frequencies, respectively F1 and F2.In this network design, at least for use same frequency Different districts, the cell ID that it is used needs to meet following two conditions：

First, do not conflict, i.e., the adjacent co-frequency cell of any two can not use same cell ID, otherwise terminal by nothing It is two different cells that method distinguishes this.

Second, do not obscure, i.e., there can not be any two co-frequency cell to use identical in all adjacent areas of cell Cell ID, otherwise, current area will be unable to correctly identify the adjacent area that the two are different.

The distribution of cell ID generally has two ways

First, centralization is different cell distribution cell ID for example by Operation ＆ Maintenance System unification；

Second, it is distributed, the Cell ID List of candidate for example is provided by Operation ＆ Maintenance System, by each cell can With random selection one in cell ID.

Identify cell using PSS and SSS in LTE system, wherein PSS uses ZC sequences, SSS uses m-sequence, cell ID by PSS signal sequencesWith SSS signal sequencesBoth are common to determine, i.e.,PSS have 3 it is different Sequence, SSS then has 168, and both can determine that totally 504 mutually different cell ID jointly.

PSS and SSS can also be referred to as primary synchronization channel（Physical Synchronization Channel, PSCH） With auxiliary synchronization channel (Secondary Synchronization Channel, SSCH).PSS sends one in each field (5ms) It is secondary, and using identical running time-frequency resource position, SSS is similar to.Fig. 2 and Fig. 3 give FDD in the prior art （Frequency Division Duplex, FDD）System and time division duplex（Time Division Duplex, TDD）In system The time-domain resource that PSS and SSS take, by taking FDD system as an example, SSS/PSS respectively in the subframe 0,5 of each radio frames first Most latter two OFDM in individual time slot（Orthogonal Frequency Division Multiplexing, OFDM） Sent in symbol.

The frequency domain resource that PSS and SSS take in systems is identical, i.e. the 6 of system bandwidth center Resource Block（RB）, Totally 72 subcarriers, wherein 62 subcarriers are used to map PSS or SSS, its remaining sub-carriers not sending signal, as shown in Figure 4.

Additionally, the SSS sequences that two 5ms fields in a radio frame send are different, and use different Scrambler, the frame head of radio frames is determined for terminal in initial synchronisation, can also reduce the general of signal peak-to-average ratio and cell ID error detections Rate.

To sum up, in LTE system in the prior art, using synchronous signal sequence, i.e. PSS and SSS joint mark cells, system 504 cell ID that can be distinguished mutually are provided altogether, require to use mutually different cell between neighbor cell in network design ID.In traditional Macro only or Macro+ low-density small cell cell deployments, it is easier to accomplish adjacent small Area uses different cell ID.But when a large amount of dense deployment small cell cells are needed, either centralized cell ID The method of salary distribution, or distributed cell ID allocation mode, will reach the requirement that neighbor cell uses different cell ID, Network planning complexity can be caused to improve, or lead to not satisfaction because cell density is excessive in the scene of part as above to want Ask, cause to occur obscuring when terminal or Network Recognition cell.

Referring to Fig. 5, the first signaling method provided in an embodiment of the present invention is comprised the following steps：

Step 50：Transmission equipment determines device identification and needs the synchronous signal sequence for sending；

Step 51：Transmission equipment is according to the device identification, synchronous signal sequence that determine and device identification set in advance The incidence relation of the physical resource used with synchronous signal sequence and transmission synchronous signal sequence, it is determined that send this to need to send The physical resource that is used of synchronous signal sequence；

Step 52：Transmission equipment sends the synchronous signal sequence that the needs send using the physical resource for determining.

Specifically, device identification and synchronous signal sequence and sending associating for the physical resource that synchronous signal sequence is used Relation can be as follows：

Wherein,It is device identification, Sync_seq_index is the identification information of synchronous signal sequence, sync_res_ Index represents the time-domain resource position or frequency domain resource position that transmission synchronous signal sequence is used, F representative function relations.Should Time-domain resource position can be wireless frame position, subframe position, OFDM symbol position etc.；The frequency domain resource position can be resource Block（RB）Position etc..

So that sync_res_index is represented and is sent the radio frames that synchronous signal sequence is used as an example, F (Sync_seq_ index,sync_res_index)=M*(sync_seq_index)+m;

Wherein, M is the number of the radio frames included in radio frames set set in advance, and m is to send synchronous signal sequence Numbering of the radio frames for being used in the radio frames set, m ∈ 0,1 ... M-1 }.

Synchronous signal sequence in this method can include master sync signal（PSS）Sequence and auxiliary synchronous signals（SSS）Sequence Row；Now,Wherein,It is PSS sequences,It is SSS sequences.Certainly, synchronous letter Number sequence can also be the new synchronous signal sequence different from existing sequence, such as time-frequency resource maps mode is not equal, only To define inconsistent synchronous signal sequence can be assumed that it is new synchronous signal sequence with existing standard.

Transmission equipment in this method can be base station, and device identification is the cell ID under the base station；Or, transmission sets Standby is terminal, and device identification is the terminal iidentification of the terminal.

In this method, the equipment that sends can be base station, and device identification is the cell ID under the base station, and receiving device is for eventually End；Or,

Transmission equipment is terminal, and device identification is the terminal iidentification of the terminal, and receiving device is another terminal.

Give multiplexing existing PSS/SSS sequences in Figure 11, i.e.,And the example of M=4, In this example, distinguishable cell ID numbers expand to 2016 by 504 in the prior art in network.In actual applications During configuration cell ID, small in network can be divided into four groups, the cell in each group is sent out in identical physical resource position Synchronizing signal (PSS/SSS) is sent, but uses different synchronous signal sequences.Therefore, also can using m as cell ID group sequence numbers, and Synchronizing signal (PSS/SSS) sequence of transmission is the ID sequence numbers within a small district's groups, i.e., cell ID sequence numbers are by two-stage sequence number structure Into.

When cell ID combines determination by the physical resource position that synchronous signal sequence is used with transmission synchronous signal sequence When, the physical resource position can be identified by the wireless frame number in upper example, it would however also be possible to employ other modes, such as subframe Numbering, OFDM symbol numbering, frequency domain resource numbering etc..Concrete mode is similar with such scheme, is one possible thing of setting Reason resource collection, by the actual sequence number for sending physical resource that synchronous signal sequence used in above-mentioned resource collection, with And synchronous signal sequence determines cell ID jointly.

Wherein,It is device identification, Sync_seq_index is the identification information of synchronous signal sequence, control_ Info is the content that the control information by detecting determines, F representative function relations.

For example, F (Sync_seq_index, control_info)=N* (sync_seq_index)+n;

In step 80, receiving device can detect the control information that transmission equipment sends on PBCH.

In this method, synchronous signal sequence can include PSS sequences and SSS sequences；Now, Wherein,It is PSS sequences,It is SSS sequences.

As N=4, the control information of 2bits can be transmitted in PBCH, in this example, distinguishable cell ID numbers in network Mesh expands to 2016 by 504 in the prior art.When configuring cell ID in actual applications, can be by the small differentiation in network It is four groups, the cell in each group sends synchronizing signal (PSS/SSS) in identical physical resource position, but using different same Step signal sequence.Therefore, also can be using n as cell ID group sequence numbers, and synchronizing signal (PSS/SSS) sequence for sending is small for one ID sequence numbers within district's groups, i.e. cell ID sequence numbers are made up of two-stage sequence number.

It should be noted that step 70- steps 72 can be first carried out, then perform step 80- steps 81, namely step 80- Step 82, step 80- steps 81 may be constructed a complete embodiment.
