Number of times.Second preset times are less than the first preset times.
Step 405：Increase T_bc_all_interval.
Step 406：Keep T_bc_all_interval constant.
It should be noted that：T_bc, T_bc_all, T_bc_gap and T_bc_all_interval are cell by network side
Each BS unification configurations in group.
In the present embodiment, the BS in small district's groups can be in MBSFN（Multicast Broadcast Single
Frequency Network, broadcast multi-broadcasting of eating dishes without rice or wine）Uplink and downlink timeslot proportioning information is sent in subframe or special subframe of eating dishes without rice or wine.
Wherein, MBSFN sub-frame is the existing subframe for multicast defined in LTE TDD standards.In the present embodiment, in advance
Two kinds of MBSFN sub-frames --- Tx subframes and Rx subframes are first defined, to send subframe, Rx subframes are reception subframe to Tx subframes.Each
BS sends uplink and downlink timeslot and matches information using Tx subframes in turn, and enabling Tx subframes transmission uplink and downlink timeslot in any one BS matches somebody with somebody
While than information, other BS enable Rx subframes and receive uplink and downlink timeslot proportioning information.BS sends up-downgoing in MBSFN sub-frame
The schematic diagram of time slot proportion information is referred to shown in Fig. 5.Wherein, BS numbers are N number of in small district's groups in Fig. 5.
Special subframe is a kind of special son for including uplink again comprising downlink transfer defined in LTE TDD standards

It is to perform step 103, if not, return that step 101 is performed, when continuing to the up-downgoing that other base stations send in small district's groups
Gap matches information.
If a small district's groups include N number of BS, any one BS can be by judging whether to receive during N-1 up-downgoing
Gap matches information to judge whether to receive the uplink and downlink timeslot proportioning information that every other BS sends in small district's groups.
Above-mentioned deterministic process can also be judged by other means.For example, in the present embodiment, uplink and downlink timeslot is matched somebody with somebody
Can also include that information sends mark than information.When any one BS sends uplink and downlink timeslot proportioning information in small district's groups, will
Information sends mark and is set to 1, therefore, it can by judging that information sends mark described in the uplink and downlink timeslot proportioning information that BS sends
Whether knowledge is set to 1 matches information to judge whether to receive the uplink and downlink timeslot that every other BS sends in the small district's groups.
Certainly, deterministic process can at random be set according to different application scene, and this present embodiment is not any limitation as.
Herein it may be noted that：Network side real-time detection BS working conditions, after certain BS breaks down, network side will more
BS numbers after new are sent to the BS of each normal work with the cell Groups List for needing to receive uplink and downlink timeslot proportioning information.
Step 103：Uplink and downlink timeslot proportioning information and the every other BS places for receiving according to cell where itself

Wherein, it is described to show that unified uplink and downlink timeslot proportioning includes：
According to formulaUnified uplink and downlink timeslot proportioning is drawn,
Wherein, N is the BS numbers in small district's groups.
Step 104：In preset time period, the uplink and downlink timeslot of cell where itself is configured to unify up-downgoing
Time slot proportion.
BS is being carried out when uplink and downlink timeslot is matched, it is necessary to will unified uplink and downlink timeslot proportioning and the existing uplink and downlink timeslot of standard
Proportioning is contrasted, when comparing result is unified uplink and downlink timeslot proportioning consistent with the existing uplink and downlink timeslot proportioning of standard, directly
Connect and configured according to unified uplink and downlink timeslot；It is unified uplink and downlink timeslot proportioning existing with standard up and down in comparing result
When row time slot proportion is inconsistent, one is chosen from the existing uplink and downlink timeslot proportioning of standard with the unified uplink and downlink timeslot proportioning
The immediate existing uplink and downlink timeslot proportioning of standard, is configured according to the existing uplink and downlink timeslot of immediate standard.Mark
Accurate existing uplink and downlink timeslot proportioning is as shown in table 2.
The uplink and downlink timeslot of table 2 is matched
In the present embodiment, preset time period can be a subframe in radio frames, and all BS in small district's groups
Preset time period is identical.All BS in i.e. small district's groups in identical preset time period, respectively by the upper of respective place cell
Descending time slot is configured to unify uplink and downlink timeslot proportioning.Wherein, configuration process one preset time period of correspondence.Not
