Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
When neighboring community carries out the information transmission of different directions (upstream or downstream) on same running time-frequency resource, it will band
Come cross link interference (Cross-Link Interference, CLI), such as BS (base station)-BS, UE (user terminal)-UE it
Between interference, as shown in Figure 1.
In order to be fed back faster, and meet the transmission of low time delay business, introduces self-contained (self-
Contain) frame structure is fixed as uplink/downlink control information transmission from beginning to end, avoids most important as shown in Figure 2 a and 2 b
Control section is interfered, and intermediate symbols flexibly configurable is the transmission of upstream or downstream data, and uplink and downlink switching, which needs to be arranged, to be protected
Shield interval.
It newly eats dishes without rice or wine inner dynamic configuration downstream transmission direction in 5G, it will lead to different types of CLI, possible frame structure
Mode is not limited to the mode that Fig. 3 a~Fig. 3 f is presented as shown in Fig. 3 a~Fig. 3 f.

2) only have control area to have CLI (referring to Fig. 3 b and Fig. 3 c)；
3) data area and control area can all have CLI (referring to Fig. 3 d, Fig. 3 e and Fig. 3 f).
According to disturbed condition, two kinds of dynamic tdd frame structure can be defined, the first kind (abbreviation type1) is only
Allow to have CLI in data area, i.e., only self-contained frame can be configured to dynamically；Second Type (abbreviation type2) is data
All there is CLI with control area.
Flexible duplex technology can dynamically distribute uplink and downlink resource according to uplink and downlink business situation of change, make ascending-descending subframes
The proportion of resource and the proportion of uplink and downlink service traffics match, and effectively improve resource utilization ratio.Such as it is a kind of flexibly double

Can flexibly it match.Only in data area, there are CLI for this frame structure.
It is not influenced by cross link interference to guarantee control channel as far as possible, the present embodiment proposes a kind of based on interference
The frame structure configuration method of measurement and base station, that is, the interference information that base station in service sector is obtained according to measurement, flexible configuration selection
Two kinds of dynamic tdd frame structures (i.e. above-mentioned type type1 and type type2).
Referring to Fig. 5, the frame structure configuration method based on cross link interference measurement of one embodiment is shown in figure
The executing subject of process, this method is base station in service sector, and specific step is as follows
Step 501 obtains cross link interference measure；
In the present embodiment, cross link interference measurement mainly include interference measurement between base-station, base-station and user with

The concrete mode of interference measurement.
Optionally, cross link interference measure is obtained in such a way that interfering information inter-base station exchanges, specifically, passed through
Backhaul link or space interface signaling obtain the shared cross link interference measure in other base stations, such as can be established with X2 interface one
Between a base station in service sector and adjacent one or more base stations, intercorrelation interference information when needed.
Step 502 judges whether cross link interference measure is greater than preset threshold value, if so, executing step
503；Otherwise, step 504 is executed；
Above-mentioned preset threshold value can be arranged as the case may be, not limit its occurrence in the present embodiment.
Step 503, the dynamic tdd frame structure that configuration tdd frame structure is the first kind, the dynamic TDD of the first kind
The dynamic subframe of frame structure is self-contained (self-contaied) frame structure.
Step 504, the dynamic tdd frame structure that configuration tdd frame structure is Second Type, the dynamic TDD of the Second Type
The transmission direction that the dynamic subframe of frame structure can configure subframe according to own service state is upstream or downstream.
Optionally, with continued reference to Fig. 5, method further include: step 505.

Between, intercorrelation interference information when needed.After first step progress interference measurement determines disturbance level, need through backhaul chain
Road or OTA (Over-the-Air Technology, technology of eating dishes without rice or wine) signaling give this information sharing to other base stations.
Step 3, dynamic frame structure configuration.
Interference information interaction between base station is used to assist carrying out flexibly duplexing frame structure type configuration.In step 2 base station
Between after interactive interference information, base station carries out disturbance level judgement to interference measurement information, if disturbance level is less than and to pre-set
Interference threshold value indicates to interfere very little without the cross link of cross link interference or minizone at this time, then at this time can be with
Configure tdd frame structure to the dynamic tdd frame structure of Second Type, subframe can be according to own load service condition flexible configuration
Subframe downstream transmission direction, i.e., start dual-mode in corresponding subframe；If disturbance level is greater than the interference for realizing setting
Threshold value indicates that minizone cross jamming is serious at this time, can configure tdd frame structure to the dynamic of the first kind at this time
Tdd frame structure, i.e., each subframe must be self-contained frame structure, protect to control channel.
The information sharing that step 4, dynamic frame structure configure.
After frame structure is configured to dynamic TDD by a base station, need the configuration information (the i.e. downstream transmission of subframe
Direction) share to other base stations, other base stations according to the frame structure configuration information received, itself payload traffic state and
Interference information determines the frame structure Configuration Type of its own.The information of interaction is including but not limited to following interior between base station at this time
Hold: being configured to the sub-frame number of dynamic TDD, the subframe index that can be configured to dynamic TDD etc..
When executing the above method, a DYNAMIC-CONFIG SUBFRAME-INDICATOR (dynamic can also be increased
