In specific implementation, user equipment access service base station is in RRC connection status, and serving BS passes through the user equipment
Or the measurement report of other users equipment knows that, there are some unknown adjacent area, measurement report can indicate that the physics of the adjacent area is small
Area identifies (such as can be Cell1).Since other information of the serving BS to the adjacent area is not known about, in order to the cell
There is comprehensive understanding, and in order to be that other users device configuration measures, serving BS can indicate in reporting instruction information
The Physical Cell Identifier (Physical Cell Identifier, PCI) for the cell that user equipment needs to measure, and it is sent to use
Family equipment.Specifically, serving BS can pass through wireless heterogeneous networks (Radio Resource Control, RRC) signaling
Instruction information is reported to user equipment transmission.
Then in step s101, what user equipment reception serving BS was sent reports instruction information.User equipment needs to survey
The cell of amount is the adjacent area of serving cell, that is to say, that the cell that Physical Cell Identifier is directed toward is the adjacent area of serving cell.Specifically
For, user equipment can report instruction information by receiving RRC signaling to obtain.
And then in step s 102, the cell that user equipment is directed toward the Physical Cell Identifier measures, and at least
Obtain the period of the synchronization signal burst collection for the cell that the Physical Cell Identifier is directed toward.
It will be apparent to a skilled person that user equipment can use existing skill to the process that cell measures
Any enforceable measurement method, the embodiment of the present invention are without limitation in art.
In step s 103, user equipment reports information reporting to the serving BS for described.Serving BS can be from
Report period (the SS burst set of the synchronization signal burst collection for the cell for knowing that Physical Cell Identifier is directed toward in information
Periodicity), it is referred to as the synchronization signal block collection period, thus being directed to the cell for subsequent user device configuration
Measurement when, can by the synchronization signal of the cell happen suddenly collection period assignment in measuring configuration.Specifically, user equipment
Information is reported described in can reporting by uplink RRC (Radio Resource Control) signaling.
The user equipment of the embodiment of the present invention receive base station report instruction information after, the adjacent area of serving cell is carried out
Measurement, and the period of the synchronization signal burst collection for the cell that Physical Cell Identifier is directed toward at least is obtained, and report to serving BS,
So that the period that serving BS can use the synchronization signal burst collection of adjacent area surveys for the user device configuration of subsequent access
Amount, so that subsequent user equipment preferably measures adjacent area.
Preferably, step S102 may comprise steps of: detect the synchronization for the cell that the Physical Cell Identifier is directed toward
Block, Master Information Block and system information block, with obtain the cell that the Physical Cell Identifier is directed toward Cell Global Identification and
The period of synchronization signal burst collection, and information is reported described in addition.
In specific implementation, user equipment receive report instruction information after, begin trying read Physical Cell Identifier be directed toward
Cell synchronization signal block and Master Information Block (Master Information Block, MIB).It is obtained required for user equipment
The information of cell be likely located at other systems message, such as system information block 1 (System Information Block1,
SIB1), then UE also needs to read the system message in the other systems block of information of the cell at this time.Specifically, user equipment
It receives after carrying the RRC signaling for reporting instruction information, begins trying the master for reading the cell Cell1 that Physical Cell Identifier is directed toward
System message in synchronization signal, secondary synchronization signal and MIB and SIB1.Then user equipment obtain the cell cell it is complete
Office's mark (Cell Global Identifier, CGI), the SS burst set period of the cell；And pass through uplink RRC (Radio Resource Control) signaling
To CGI the and SS burst set period of the serving base stations report cell.

Block, such as system information block 2 (System Information Block2, SIB2), 3 (System of system information block
Information Block3, SIB3) etc., the embodiment of the present invention is without limitation.
Optionally, if the cell of Physical Cell Identifier direction is different from the frequency of serving cell, user equipment needs
Using measurement gap or discontinuous received inactivation time, the synchronization signal for reading the cell that Physical Cell Identifier is directed toward is gone
Block and Master Information Block.
Further, step S102 can with the following steps are included: calculate cell that the Physical Cell Identifier is directed toward with
Synchronization time difference between the serving cell of the serving BS, to report information described in addition.
In the present embodiment, synchronization time difference can be indicated using absolute time；Orthogonal frequency division multiplexing can also be used
(Orthogonal Frequency Division Multiplexing, OFDM) symbol indicates；Communication protocol can also be used
The minimum time unit of definition indicates, such as minimum time unit Ts is 1/ (15000 × 2048) s.
The user equipment of the embodiment of the present invention can also calculate the synchronization time difference of serving cell Yu its adjacent cell, and report

In one embodiment of the invention, can calculate the cell that the Physical Cell Identifier is directed toward start frame and the service
The first time of the start frame of cell is poor, and to report information described in addition, the start frame includes starter system frame number and starting
Subframe numbers.
In the present embodiment, the cell that Physical Cell Identifier is directed toward is Cell 1, the System Frame Number (System of cell Cell 1
Frame Number, SFN) it is 0 and subframe numbers are moment 1, the SFN=0 and subframe of serving cell at the time of be corresponding to 0
Number=0 corresponding at the time of be the moment 2, then can calculate the difference at moment 1 Yu moment 2.
In a change case of the invention, following steps can be executed and calculate synchronization time difference: determining the Physical Cell Identifier
The strongest first synchronization signal block of signal strength in multiple synchronization signal blocks of the cell of direction；Calculate first synchronization signal
Second time difference of the start frame of block and the serving cell, described to report information include second time difference and described first
The mark of synchronization signal block.
In the present embodiment, the cell that Physical Cell Identifier is directed toward is Cell 1, and cell Cell1 may include multiple synchronous letters
Number block.User equipment can measure the signal strength of multiple synchronization signal blocks, such as can be Reference Signal Received Power
(Reference Signal Receiving Power,RSRP).User equipment calculates the synchronous letter of signal strength strongest first
Second time difference of the start frame of number block and the serving cell, and the second time difference and the second time difference are reported into service base
It stands.
For example, cell Cell1 have 16 synchronization signal blocks: SS block0, SS block1, SS block2 ..., SS
Block15, UE measurement identify 3 SS block:SS block4, SS block5 and SS block6 therein, what UE was measured
Signal strength is followed successively by RSRP1, RSRP2 and RSRP3, and RSRP2 > RSRP1 > RSRP3.Then UE is by SS block5 and the clothes
The second time difference of start frame for cell of being engaged in and the mark of SS block5 are reported to serving BS.That is, by cell
Time at the time of at the time of corresponding to the SS block5 of Cell 1 with corresponding to serving cell SFN=0 and subframe numbers=0
Difference is reported to serving BS, and furthermore UE needs to indicate when reporting the time difference information of measured SS block 5.
In another change case of the present invention, following steps can be executed and calculate synchronization time difference: calculate the described first synchronous letter

State the mark of the first synchronization signal block.
In the present embodiment, after determining that the strongest first synchronization signal block of signal strength is SS block5, SS can be calculated
Time difference corresponding to the service SS block of block5 and serving cell, and by the time difference and the mark of SS block5
It is reported to serving BS.
In the another change case of the present invention, following steps can be executed and calculate synchronization time difference: determine the physical area mark
Know the strongest multiple second synchronization signal blocks of signal strength in the multiple synchronization signal blocks for the cell being directed toward；It calculates separately described more
4th time difference of the start frame of a second synchronization signal block and the serving cell, and calculate the multiple second synchronization signal
The mean value of block corresponding 4th time difference, to report information described in addition.
In the present embodiment, signal in the multiple synchronization signal blocks for the cell Cell1 that the Physical Cell Identifier is directed toward is determined
The strongest multiple second synchronization signal blocks of intensity: SS block4, SS block5 and SS block6, calculate SS block4, SS
Average value at the time of block5, SS block6 are with corresponding to serving cell SFN=0 and subframe numbers=0, and report to clothes
Business base station.
It is understood that the quantity of the second synchronization signal block can carry out matching for adaptability according to actual application environment
It sets, the embodiment of the present invention is without limitation.
In the another change case of the present invention, the synchronization time difference is indicated using synchronization identifier, the synchronization identifier
Whether the cell for indicating that the Physical Cell Identifier is directed toward is synchronous with the serving cell.
In the present embodiment, in addition to absolute time, OFDM, communication protocol definition minimum time unit other than, can also use
Synchronization identifier indicates the synchronization time difference.For example, synchronization identifier occupies 1 bit, 0 indicates that Physical Cell Identifier is directed toward
Cell it is synchronous with the serving cell, 1 indicate Physical Cell Identifier be directed toward cell it is asynchronous with the serving cell；Or
Person, 1 indicates that the cell of Physical Cell Identifier direction is synchronous with the serving cell, and 0 indicates the cell that Physical Cell Identifier is directed toward
It is asynchronous with the serving cell.
It is preferably, described that report information further include the number of beams of the cell that the Physical Cell Identifier is directed toward and/or same
Walk the subcarrier spacing of block.
In the present embodiment, the number of beams for the cell that Physical Cell Identifier is directed toward can also be reported to service by user equipment
Base station.The number of beams can be the total quantity of the wave beam of the cell of Physical Cell Identifier direction, such as 16；The numbers of beams
Amount is also possible to the quantity of the wave beam for the cell that the Physical Cell Identifier that user equipment detects is directed toward, such as 3.
It is understood that the number of beams is also possible to the quantity of synchronization signal block.
Further, since the wave beam for the cell that Physical Cell Identifier is directed toward can use different subcarrier spacings
(numerology), different subcarrier spacings corresponds to different Transmission Time Intervals (Transmission Time
Interval, TTI), therefore user equipment can also measure to obtain the subcarrier spacing of the synchronization signal block of the cell, and report
To serving BS.
Preferably, described report indicates that information further includes at least one message identification, and the message identification indicates on described
It notifies the type of breath.
In the present embodiment, when reporting information includes the content of one or more types, serving BS can refer to reporting
Show the type for indicating the content that user equipment needs to report in information by message identification.
Further, the message identification includes unified information mark and single piece of information mark, unified information mark instruction
