With the multiple base stations under SFA at modulation coding techniques identical with same frequency employing of identical time, send phase
Same data, to improve the reception of Cell Edge User.For realizing MBSFN transmission means, connecing
Introducing MCE (Multi-cell/multicast Coordination Entity) logic entity in networking, it is right to be responsible for
In MBSFA, the radio broadcasting resource of all base stations is allocated and manages.
In TDD MBMS system, under each MBMS region (MBMS service area)
Can include down organizing MBSFN (the Multimedia Broadcast that different MBMS are provided more
Multicast service Signal Frequency Network multicast broadcast multimedia service SFN) district
Territory.Each MBSFN region is made up of adjacent single community of multiple offer same MBMS business.Often
All communities in one MBSFN region use identical ratio of uplink subframe to downlink subframe.MBSFN region
Between can use different ratio of uplink subframe to downlink subframe, such as MBSFN region 1 according to class of business demand
Use 0: 10 proportioning；Nearby MBSFN Area 2 uses 1: 8 proportioning.Owing to MBSFN edge has
Retaining community (Reserve cell) and only transmit community (Transmission only Cell) and exist, it acts on
In ensureing that MBSFN region is not subject to outside frequency interferences, and can overcome due to adjacent MBSFN
The interference that region produces due to the different up-downgoing proportioning of employing.The interregional ascending-descending subframes of MBSFN is joined
Application and the reservation community of ratio are controlled by MCE with the configuration only transmitting community.
In existing LTE TDD clean culture and MBMS mixed carrier system, different owing to also existing 8 kinds
Ratio of uplink subframe to downlink subframe mode.System carries out ascending-descending subframes in difference by base station according to business demand and joins
Semi-static switching between Bi.Base station can reset the son of this community by " cold start-up " or other modes
Frame proportioning.After subframe proportioning determines, in a period of time, only use a kind of ratio of uplink subframe to downlink subframe.
But, the present inventor is found by in-depth analysis: owing to can only use within a period of time
A kind of ascending-descending subframes configuration, if system has only to a sub-frame of uplink according to demand, needing 20ms,
Then can not meet this kind of demand according to the proportioning of existing subframe, if using 1: 8+1: 8 in 20ms
Proportioning, then use two sub-frame of uplink in 20ms, cause the waste of uplink transmission resource.It addition,
Prior art base station within a period of time carries out resource distribution, transmission data according to the proportioning of 0: 10, one
Resetting after ratio of uplink subframe to downlink subframe is 1: 8 according to demand when base station after the section time, base station is i.e. according to 1: 8
Up-downgoing resource distribution distribution, transmit data, the most visible, only use 0: 10 within a period of time
Ratio of uplink subframe to downlink subframe, can cause and downlink data transmission only occurs, and not have transmitting uplink data, and
The next time period only uses 1: 8 ratio of uplink subframe to downlink subframe, can cause on the most only using one
Row data are transmitted, and use single ratio of uplink subframe to downlink subframe not only can make up-downgoing in the most each time period
Data transmission is uneven, and can not meet system demand timely.It addition, existing ascending-descending subframes
Proportioning the most only supports the downstream transmission of the generating period of 10ms, it is impossible to support the generation week of more than 10ms
Phase downstream transmission.
