Description
Technical field
The present invention relates to moving communicating field, relate to the launching technique of TDD system signal particularly.
Background technology
Fig. 1 is a kind of wireless frame structure schematic diagram of tdd systems.In this schematic diagram, the radio frames of a 10ms comprises two isometric fields, and the length of each field is 5ms.Each field comprises 7 general time slots (also claiming subframe) and 3 special time slot DwPTS, GP and UpPTS again.
In 7 general time slots, the length of each time slot is 675us, and for simplified system realizes that TS0 always is assigned to descending time slot, the auxiliary synchronous signals (S-SCH) that is used for down-going synchronous sends on the middle bandwidth of this last symbol of time slot.TS1 always is assigned to ascending time slot, other 5 general time slots, that is and, TS2～TS6 can be assigned as up or descending time slot flexibly according to service needed.
When certain general time slot is descending time slot, each time slot comprises 8 or 9 symbols that send according to the OFDM mode, and (Cyclic Prefix of number of symbols and symbol is relevant, when Cyclic Prefix is the regular circulation prefix, each time slot comprises 9 symbols, when Cyclic Prefix was extended cyclic prefix, each time slot comprised 8 symbols).In this time slot, control channel is usually at several symbols of the front of time slot, and the DSCH Downlink Shared Channel that sends user's general data is then at several symbols of the back of time slot.
When certain general time slot is ascending time slot, each time slot comprises 8 or 9 symbols that send according to the single carrier mode, and (Cyclic Prefix of number of symbols and symbol is relevant, when Cyclic Prefix is the regular circulation prefix, each time slot comprises 9 symbols, when Cyclic Prefix was extended cyclic prefix, each time slot comprised 8 symbols).In this time slot, control channel occupies the position, both sides of system bandwidth usually, and the duration is a time slot, by obtaining frequency diversity gain two sideband position frequency hoppings; The Uplink Shared Channel that sends user's general data is then in the rest position of system bandwidth, and the duration also is a time slot.
Concerning any communication system, 1/ layer of 2 control of layer signaling retransmits and all is very important scheduling, link circuit self-adapting, the mixing that depends on channel.In the transmission of time division duplex upstream control signaling, it is defeated to require it to upload a subframe, and carries out frequency hopping in the subframe.The transmission form of 1/ layer of 2 signaling of its layer has two kinds:
(1) signaling of transmitting simultaneously with data, this signaling and data are time division multiplexing on same running time-frequency resource.
(2) with data not simultaneously the transmission signaling; mainly be that ack/nack is replied (Acknowledged/Non-acknowledged; be called for short ACK/NACK) and channel quality indication (Channel Quality Indication; be called for short CQI) signaling, this signaling is only transmitted on the Resource Block of both sides near boundary belt up and down in bandwidth.Each user's ACK/NACK and CQI are mapped to permanent width of cloth zero correlation (the Constant Amplitude ZeroAuto-correlation Code on the frequency domain, be called for short CAZAC) certain cyclic shift of sequence, the piece expansion that ACK/NACK also carries out orthogonal code in time is to realize that the multi-user's is multiplexing.
In frequency division duplex system, the ascending control channel duration is 1ms, and the duration of the ascending control channel of tdd systems is 0.675ms, shorter than the ascending control channel duration in the frequency division duplex system, thereby the covering that the tdd systems control channel is supported is just little, and the radius of society that causes tdd systems to support is restricted.
