Description
Technical field
The present invention relates to Long Term Evolution (LTE) system of time division duplex (TDD), relate in particular to a kind of uplink and downlink transmission method, ascending transmission method, downlink transmission method, base station and subscriber equipment (UE).
Background technology
Long Term Evolution (Long Term Evolution at 3-G (Generation Three mobile communication system) (3G) wireless interface technology, LTE) in system, support 2 class frame structures: first kind frame structure, be applicable to Frequency Division Duplexing (FDD) (FDD) and TDD system, frame length is 10ms, 20 time slots that are 0.5ms by length form, and every two continuous time slots are defined as a subframe; The Equations of The Second Kind frame structure, be only applicable to the TDD system, and with Time Division-Synchronous Code Division Multiple Access access (TD-SCDMA) system compatible, as shown in Figure 1, frame length is also 10ms, the field that it is 5ms that each radio frames is divided into 2 length (half-frame), each field is comprised of the long subframe (subframe) of 5 1ms.Subframe is divided into two kinds of common subframe and special subframes; common subframe is comprised of the long time slot (slot) of 2 0.5ms; special subframe comprises 3 special time slots: downlink transfer time slot (DwPTS); protection interval (GP) and uplink time slot (UpPTS); wherein DwPTS is used for transmitting descending master sync signal, and UpPTS is used for transmission uplink random access sequence.
Wherein, be the system of 5ms for the uplink and downlink change-over period, all comprise above-mentioned special subframe in former and later two fields, namely subframe 1 and subframe 6(are as shown in Figure 1).Be the system of 10ms for the uplink and downlink change-over period, only have first field to have special subframe, namely have master sync signal in subframe 1(subframe 6 but without GP and UpPTS, therefore can be considered the generic downlink subframe).
There is at present Cyclic Prefix (CP) configuration of two kinds of different lengths in the LTE system, be conventional CP(Normal CP) and expansion CP(Extended CP), during corresponding different CP configuration, OFDM (OFDM) symbolic number that comprises in subframe is different.When using Normal CP, comprise 14 OFDM symbols in each subframe, wherein the long CP of CP on first symbol
Normal '=160T
s, T
s=1 (15000 * 2048), the long CP of the CP on other symbols
Normal=144T
sAnd when using Extended CP, comprising 12 OFDM symbols in each subframe, its CP length is CP
Extended=512T
sIn two kinds of situations, the valid data partial-length in the OFDM symbol except CP is identical, and its length is 2048T
s(when system's sub-carriers is spaced apart 15kHz) or 4096T
s(when system's sub-carriers is spaced apart 7.5kHz).Wherein, T
s=1/ (15000 * 2048) are standard time unit.
Wherein, because common subframe is not that transmission is exactly to transmit as descending sub frame as sub-frame of uplink, even therefore in system, the up-downgoing transmission configuration is different CP, common subframe also only need to be according to the CP that uses, and the configuration of carrying out the OFDM symbol according to afore mentioned rules gets final product.And for special subframe, because it not only comprises the uplink time slot but also comprise the downlink transfer time slot, the CP that therefore corresponding up-downgoing transmission is used, will there be different configurations in the OFDM symbol in this special subframe, and in corresponding special subframe, also there is different configurations in the length of three time slots.But only provided up-downgoing transmission CP in prior art when consistent, in special subframe, the configuring condition of three slot lengths, as shown in table 1.
Table 1
When as seen from Table 1, above-mentioned configuration only shows downlink transfer and uplink and all uses conventional CP and the configuring condition of downlink transfer and the uplink special subframe when all using expansion CP.In practical application, due to when CP is expanded in the downlink transfer use, uplink can be selected conventional CP as the case may be, but use the situation of different CP for this up-downgoing transmission, still not configuration in prior art, therefore existing TDD system there is no the up-downgoing transmission that different CP configurations are used in the method support, this not only defines the application scenarios of TDD system, affected the overall performance of system, and at the descending use of the actual middle correspondence of arranging net expansion CP and up also must use expansion CP the time, the unnecessary wasting of resources will be caused.
