Embodiment
Fig. 1 is the method flow diagram that small cell Node provided by the invention obtains neighboring BS information.
As shown in figure 1, this method includes：
Step 101, it is each small cell Node and the UE allocating and measuring gaps to be communicated with each small cell Node.
It is between each small cell Node and the UE to be communicated with each small cell Node configuration measurements by network side in this step
Gap, specifically measurement gap information can be handed down to by each small cell Node and the UE by signaling message by network side.
Step 102, in the measurement gap, the separated institute in addition to random access procedure of each small cell Node and UE

Upper transmission control information.
Step 103, in the measurement gap, each small cell Node receives other when itself does not send control information
The control information that small cell Node is sent, neighboring BS information is obtained according to the control information of reception.
It can be seen that method shown in Fig. 1 is by the UE allocating and measuring gaps that are communicated for small cell Node and with small cell Node, and
Change control channel resource location of each small cell Node in measurement gap so that each cell section in the measurement gap
Point configures control channel in a time multiplexed way, and sends control information on a control channel, and small cell Node is in the measurement
When not sending control information in gap, simulation UE monitors the control information that other small cell Nodes are sent, so as to obtain neighbour
Area's information.
Wherein, in the measurement gap, separated the owning in addition to random access procedure of each small cell Node and UE
Communication, on the one hand can ensure that each small cell Node needs not continue to service for UE in cell, it is monitored so as to simulate UE behaviors
The control information that his small cell Node is sent, on the other hand, in order to ensure that UE can access cell, it is therefore desirable to keep random
Access procedure is communicated, and UE can also be avoided can not to access cell.
Wherein, each small cell Node configures control channel in the measurement gap using time division multiplexing mode, and is controlling
Control information is sent on channel processed can use following several ways：
Mode one, each small cell Node is according to the cell ID of itself（ID）Determine that itself is sent shared by control information
Time.
Mode two, time of each small cell Node according to shared by high-level signaling determines itself transmission control information.
Mode three, each small cell Node can be used in sending out of described measurement gap in the time of the control information with
Machine selects itself to send the time shared by control information.
Each small cell Node configures control channel in the measurement gap using time division multiplexing mode, and in control channel
During upper transmission control information, control information can be sent using time division multiplexing mode using subframe as the unit time, can also be with just
Hand over frequency division multiplexing（OFDM）Symbol is the unit time to send control information using time division multiplexing mode, specifically：
It can determine that different small cell Nodes sends control information in the measurement gap using subframe as the unit time
Shared subframe, wherein, the subframe that different small cell Nodes takes is different.
Or it can determine that different small cell Nodes is sent out in the measurement gap using OFDM symbol as the unit time
The OFDM symbol shared by control information is sent, wherein, the OFDM symbol that different small cell Nodes takes is different.
Each small cell Node in the measurement gap is exemplified below control information is sent using time division multiplexing mode
Method.
Example one：In this example embodiment, each small cell Node employing mode one determine itself to send shared by control information when
Between.
Specifically, each small cell Node can be by the cell ID of itself to predetermined value modulus, according to modulus result and institute
The corresponding relation to put in order for the unit interval that can be used in sending the control information in measurement gap is stated, determines that itself sends out
Send the time shared by control information.
Wherein, when carrying out modulo operation, the predetermined value is bigger, is generally possible to orthogonal small cell in measurement gap
Node number is more, correspondingly needs the also bigger of measurement gap configuration.
Unit interval of the modulus result with can be used in sending the control information in the measurement gap puts in order
Corresponding relation be usually to make an appointment.
For example, can about settled slight area's node ID to when the modulus result of the predetermined value is 0, the cell section
Point is in resource location specified in existing protocol 3GPP TS36.211（Referred to as existing position）Upper transmission control information, when slight
The ID of area's node is to when the modulus result of the predetermined value is n, n is offset on the basis of existing position described in the small cell Node
Integral multiple descending unit interval after send control information on obtained descending unit interval, wherein, the integral multiple is general
For 1 times, the up unit typically only at the unit interval after n descending unit interval are offset on the basis of the existing position
During the time, just continue to offset n descending unit interval, until the unit interval after skew is the descending unit interval, can be used in
Untill sending control information.
Such as, it is assumed that control information is sent using time division multiplexing mode using subframe as the unit time, what TDD radio frames used
Up-downgoing matches structure：Subframe 0 and 5 is descending sub frame, and subframe 1 and 6 is special subframe, and subframe 2 and 7 is sub-frame of uplink, son
Frame 3,4 and subframe 8,9 are descending sub frame, and the cell ID of cell 1 is 0, and the cell ID of cell 2 is 1, and the cell ID of cell 3 is 2,
Using cell ID to 10 carry out modulus, according to modulus result determine cell is sent in measurement gap control information take when
Between.
The ID of cell 1 is 0 to 10 modulus result, therefore sends control information on the existing position, specifically, when
When the control channel includes PBCH and synchronizing channel, preceding 4 OFDM of the time slot 1 of subframe 0 of the cell 1 in TDD radio frames
PBCH information is sent on symbol, in the 3rd OFDM symbol of subframe 1 and subframe 6（Subframe 6 is special subframe）The 3rd
PSS is sent in OFDM symbol, is sent in last OFDM symbol of subframe 0 and last OFDM symbol of subframe 5
SSS。
Because the ID of cell 2 is 1 to 10 modulus result, therefore cell 2 should send the subframe of control information in cell 1
On the basis of offset 1 descending sub frame, i.e., cell 2 should be sent in preceding 4 OFDM symbols of the time slot 1 of subframe 3 PBCH believe
Breath, PSS, last 1 OFDM in subframe 3 are sent in the 3rd OFDM symbol of subframe 4 and the 3rd OFDM symbol of subframe 8
SSS is sent in last OFDM symbol of symbol and subframe 8.
Because the ID of cell 3 is 2 to 10 modulus result, therefore cell 3 should send the subframe of control information in cell 1
On the basis of offset 2 descending sub frames, i.e., cell 3 should be sent in preceding 4 OFDM symbols of the time slot 1 of subframe 4 PBCH believe
Breath, PSS is sent in the 3rd OFDM symbol of subframe 5 and the 3rd OFDM symbol of subframe 9, in last 1 OFDM of subframe 4
SSS is sent in last OFDM symbol of symbol and subframe 9.
Similarly, when sending control information using time division multiplexing mode as the unit time using OFDM symbol, can utilize
The ID of small cell Node carries out modulus to the predetermined value, and when modulus result is n, the small cell Node is in the existing position
On the basis of offset the n descending OFDM symbol of integral multiple and send control information.
Example two：In this example embodiment, each small cell Node employing mode three determine itself to send shared by control information when
Between, i.e., each small cell Node can be used in sending in the time of the control information out of described measurement gap randomly chooses itself
The time shared by control information is sent, such as when using subframe as the unit time, each small cell Node is from the measurement gap
It inside can be used in sending and select itself to send the subframe shared by control information immediately in the subframe of the control information.
For example the up-downgoing proportioning structure that TDD radio frames use remains as：Subframe 0 and 5 is descending sub frame, subframe 1 and 6
For special subframe, subframe 2 and 7 is sub-frame of uplink, and subframe 3,4 and subframe 8,9 are descending sub frame, and cell 1 uses the existing position
Transmission control information is put, cell 2 can randomly choose the transmission PBCH information in preceding 4 OFDM symbols of the time slot 1 of subframe 5,
Sent out in 3rd OFDM symbol of the subframe 1 of next radio frames in the 3rd OFDM symbol of subframe 6 and in measurement gap
Send PSS, the subframe 0 of next radio frames in last OFDM symbol and measurement gap of subframe 5 last
SSS is sent in OFDM symbol.
Wherein, either employing mode one, mode two or mode three determine that each cell sends control information and taken
Unit interval, as each small cell configuration control channel, the unit interval that the different control channels of each cell take
Between interlude interval can also be unfixed, as long as each control channel is all configured on the descending unit interval i.e.
Can.
