To small base station user.In whole process, wireless access and the integrated SBS303 of passback are one and are forwarded while receiving simultaneously
The small base station of data, it is meant that pass through wireless backhaul downlink between wireless access and passback integrated SBS303 and MBS302
The data that the 305 and reception of wireless backhaul uplink 306 MBS302 is sent, then again with user 304 by under wireless access
Line link 307 and wireless access uplink 308 are forwarded to terminal user UE304.Wherein wireless backhaul downlink 305, nothing
Line passback uplink 306, wireless access downlink 307, wireless access uplink 308 share identical spectral bandwidth,
All use time division multiplexing mode.So further can be wireless access and the integrated SBS303 of passback using separating thought
It is further broken into user side 3031, base station side 3032, base station side to user side interior down link 3033, user side to base station
This four part of side interior up-link 3034.
Shown in Figure 4, Fig. 4 accesses UL, passback UL, access DL, passback DL for wireless self-feedback a new generation frame structure and matches
It puts than being 3:5:9:11 instantiation figure, a wireless frame period T of wireless self-feedback a new generation frames=10ms, packet

Return descending control signaling subframe, passback downlink data transmission subframe, GP protection intervals；The time slot protection zone is used for each control
Between signalling subframe or each data transmission subframes, can there are one or multiple protection interval GP；Specific implementation step is as follows：
S1：M initial time slot is used for signalling, including access/passback and downlink/uplink control letter
Enable, between each signalling time slot there are one or multiple protection interval GP；
S2：K subsequent time slot is used for data transmission, including access/passback and downlink/uplink data, respectively
Between data transmission slots also there are one or multiple protection intervals；
S3:The institute signed number L=28 of the sum of M and K time slot for a subframe (i.e. a cycle)；
S4：In wireless self-feedback a new generation frame, the number of time slots M for signalling, the time slot for data transmission
The value of number K can be moved according to the requirement of downlink transmission rate, the requirement of uplink transmission rate, cellular coverage
State it is configured；

Quality indicator (ChannelQualityIndex, CQI) etc.；
Specific Fig. 4 examples are for referring to, in actual application, not limited to this kind.
As shown in table 1, it is the lower 27 kinds of time slot proportions of wireless self-feedback a new generation frame tdd mode.
Analytic process is as follows：
S1：Due to GP at least need 7, signaling at least need 4, define these and all transmitted in DL, at most remaining 17
A time slot is used for carrying out data transmission；
S2：Data service in view of DL is more than UL, therefore at least should be configured 9 for the time slot of DL data transmissions,
In addition 11 time slots transmitted in DL defined above, DL timeslot numbers at least 20 altogether.
S3：Therefore the UL for accessing and returning：The ratio of the DL of access and passback may be 8:207:216:225:234:
243:252:261:27；
S4：Because of GP at least seven, in order to enable the efficiency bigger of transmission, then the timeslot number of UL or DL should be more than 7.
In conclusion the UL that can be accessed and returned：The ratio-dependent of the DL of access and passback is 8:20.Based on return
The basis that timeslot number is more than access slot number and descending time slot number is more than ascending time slot number is passed, learns wireless self-feedback tdd mode
Lower 27 kinds of time slot proportions.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
It crosses above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
