Abstract

The invention discloses a method and a device for planning identities (IDs) of physical cells and relates to mobile communication technology. The method for planning the IDs of the physical cells comprises the following steps of: acquiring the IDs of all planned neighboring cells of cells to be planned; and determining that alternative IDs meeting the avoidance principle are the IDs of the cells to be planned, wherein the avoidance principle is that: the auxiliary synchronizing signal sequences corresponding to the alternative IDs are different from the auxiliary synchronizing signal sequences corresponding to the IDs of the neighboring cells. When the IDs of the physical cells are planned, the condition that the auxiliary synchronizing signal sequences corresponding to the cells to be planned are the same as the auxiliary synchronizing signal sequences corresponding to the neighboring cells is avoided, so that synchronizing signal disturbance is avoided.

Description

A kind of physical district ID planing method and device

Technical field

The present invention relates to mobile communication technology, relate in particular to a kind of physical district ID planing method and device.

Background technology

In the TD-LTE system, because physical district ID (IDentity, the identify label number) and mechanism such as resource mapping, sign indicating number resource distribution and frequency hopping bind one by one, so the effect of the configuring of physical district ID is suitable with the effect of the scrambling code planning among the TD-SCDMA, especially in identical networking, the configuring of physical district ID is particularly important.

Physical district ID is the major decision parameter that generates the scrambler initial value in the physical channel, and particularly in broadcast channel and control channel, the correlation of physical district ID has determined the correlation of control channel scrambler, plays a part crucial to the interference whitening of channel.

Simultaneously, because physical district ID and PSC (Primary Synchronisation Code, Primary Synchronisation Code)/SSC (Supplementary Synchronisation Code, secondary synchronization code) sequence index is number one by one corresponding, disturb for fear of producing between the neighbor cell, so need reasonably plan 504 physical-layer cell ID.Wherein, PSCH (Primary Synchronization Channel, primary synchronization channel) and the descending major-minor synchronizing sequence of SSCH (Secondary Synchronization Channel is from synchronizing channel) channel bearing, be used to obtain synchronizing information, set up downgoing time and Frequency Synchronization.As shown in Figure 1, master sync signal PSC mapping DwPTS (Downlink Pilot Time Slot, descending pilot frequency time slot) the 3rd OFDM (Orthogonal frequency-division multiplexing in, OFDM) 72 subcarriers in the middle of the frequency band on the symbol, the every 5ms transmission primaries of master sync signal, the employed sequence of former and later two fields is identical in the radio frames.72 subcarriers on last OFDM symbol of auxiliary synchronous signals mapping time slot 1 and time slot 11 in the middle of the frequency band, the every 5ms transmission primaries of auxiliary synchronous signals, but the employed sequence difference of former and later two fields in radio frames.

In 3GPP 36.211, stipulated the CELL-ID planning rule among the TD-LTE, with 30 sub-districts is a cell cluster, and the CELL-ID of 30 sub-districts in cell cluster selects in different CELL-ID groups respectively, comprises 30 CELL-ID in each CELL-ID group.For example, the CELL-ID of 30 sub-districts in cell cluster selects in [0-29], and the CELL-ID of 30 sub-districts in another cell cluster selects in [30-59], thereby guarantees the scrambler quadrature of up channel.

And the scrambler quadrature of only considering up channel is much of that far from, and the planning of physical district ID not only influences the scrambler quadrature of up channel, also influences the performance of synchronizing channel.So must carry out the planning of more strict physical district ID.

Embodiment

The embodiment of the invention provides a kind of physical district ID planing method and device, is carrying out physical district ID when planning, avoids occurring the identical situation of scrambler sequence of the ID correspondence of sub-district to be planned and its neighbor cell, thereby has avoided the synchronizing signal interference.

Generally speaking, physical-layer cell ID has 504 in the LTE system, from 0-503, can be expressed as:

Wherein,

Be physical layer ID group id, its scope is 0～167,

Be physical layer ID sign in the group, its scope is 0～2,

Represent the sequence index number of auxiliary synchronous signals,

Represent the sequence index number of master sync signal.

All unique corresponding one of each sub-district ID

Be worth also corresponding one group of m0 value and m1 value, this m0 value and m1 value are used to generate scrambler sequence.

Because the sequence index of sub-district ID and main synchronizing sequence PSC/ secondary synchronization sequences SSC is number corresponding one by one, produce for fear of neighbor cell and disturb, need so 504 physical-layer cell ID are reasonably planned.PSC has 3 master sync signals, and call number is

Will avoid the interference between the neighbor cell during networking, neighbor cell adopts different main synchronizing sequences preferable.

Auxiliary synchronous signals sequence SSC comprises 168 sequences, and call number is

The m sequence that has two different cyclic shifts in each SSC sequence, as shown in Figure 2, master sync signal sequence 201 and auxiliary synchronous signals sequence 202 are the 5ms transmission primaries, the cyclic shift of the m sequence that exists in each SSC sequence is different, and parameter S crambling is then identical with Zadoff-Chu.

Sequence d in the auxiliary synchronous signals (0) ..., d (61) is to be that the cascade that interweaves of 31 binary sequence forms by two length.The sequence of cascade uses scrambler sequence to carry out scrambling, and scrambler sequence is provided by master sync signal, that is:

0≤n≤30 wherein.

Two different cyclic shifts, that is:

$c_0\left(n\right)=\tilde{c}\left((n+N_{\mathrm{ID}}^{\left(2\right)})\mathrm{mod}31\right)$

$c_1\left(n\right)=\tilde{c}\left((n+N_{\mathrm{ID}}^{\left(2\right)}+3)\mathrm{mod}31\right)$

Wherein $N_{\mathrm{ID}}^{\left(2\right)}\∈\left\{\mathrm{0,1,2}\right\}.$

Second group of scrambler determined by first group of secondary synchronization sequences, and the secondary synchronization sequences that is on the odd subcarriers is carried out the secondary scrambling.Second group of scrambler sequence With

Be defined as the m sequence according to following formula

Cyclic shift, that is:

$z_1^{\left(m_0\right)}\left(n\right)=\tilde{z}\left((n+\left({\mathrm{<figure-callout\; id="0"\; label="m"\; filenames="HDA0000043405200000011.png"\; state="\{\{state\}\}">m</figure-callout>}}_0\mathrm{mod}8\right))\mathrm{mod}31\right)$

$z_1^{\left(m_1\right)}\left(n\right)=\tilde{z}\left((n+\left({\mathrm{<figure-callout\; id="0"\; label="m"\; filenames="HDA0000043405200000011.png"\; state="\{\{state\}\}">m</figure-callout>}}_0\mathrm{mod}8\right))\mathrm{mod}31\right)$

When preventing search cell, the erroneous judgement of sub-district ID need increase the isolation of auxiliary synchronous signals sequence between sub-district to be planned and neighbor cell as far as possible, and the above-mentioned purpose that the auxiliary synchronous signals sequence is carried out twice scrambling also is this.

Therefore, the embodiment of the invention is disturbed for avoiding synchronizing signal, and a kind of physical district ID planing method is provided, and as shown in Figure 3, this method comprises:
