Description
Technical field
The present invention relates to the communications field, the sending method and the device of up-downgoing percent information in a kind of tdd systems.
Background technology
Time division duplex (Time Division Duplex, TDD) system key character is, the subframe that is used for the up-downgoing transmission is configurable.The frame structure of LTE (Long Term Evolution, Long Term Evolution) system TDD mode, as shown in Figure 1.In this frame structure; A 10ms (307200Ts; Radio frames 1ms=30720Ts) is divided into the field of two 5ms, and it is 0.5ms (15360Ts) time slot and 3 special time slots that each field comprises 8 length: descending pilot frequency time slot DwPTS (Downlink Pilot Time Slot), protection be GP (Guard Period) and uplink pilot time slot UpPTS (Uplink PilotTime Slot) at interval.The length of these three each time slots of special time slot is configurable, but total length is 1ms (30720 Ts).The time slot of per two 0.5ms is formed the subframe that length is 1ms, is numbered subframe #0～subframe #9, and wherein, subframe #1 and subframe #6 comprise above-mentioned said special time slot, and subframe #0 and subframe #5 and DwPTS are fixed as descending time slot.Also there is another kind of model F DD (Frequency Division Duplex, FDD) in current LTE system.
Physical Control Format Indicator Channel can carry 2 bit informations, as the quantity of the OFDM of representing transmitting physical downlink channel control (Orthogonal Frequency DivisionMultiplexing is called for short OFDM) symbol; In general subframe; The quantity that is used as the OFDM symbol of transmitting physical downlink channel control is 1,2,3, needs 2 bit informations to represent, in DwPTS; The quantity that is used as the OFDM symbol of transmitting physical downlink channel control is 1,2; Only need 1 bit information just can represent that like this, the Physical Control Format Indicator Channel among the DwPTS can carry other information of 1 bit again.
Under above-mentioned frame structure, the ratio of up-downgoing (referring to general uplink and downlink timeslot, non-special time slot) is relevant with switching cycle.When switching cycle is 5ms, and during former and later two 5ms identical, the up-downgoing ratio has four kinds of options: 1: 3/2: 2/3: 1/3: 5.When switching cycle was 10ms, because subframe #5 and DwPTS are fixed as descending sub frame, therefore, the up-downgoing ratio also had three kinds of options: 6: 3/7: 2/8: 1.Wherein, the selection in 5: 3 5ms cycles and 10: 0 10ms cycles is still waiting further discussion.
About up-downgoing switching proportion information in any transmission problem; Current also do not have to come to a conclusion; Wherein a kind of scheme is to go up at Dynamic Broadcast Channel D-BCH (Dynamic Broadcast Channel) to send; But in realizing process of the present invention, the inventor finds that the user need obtain the positional information of Dynamic Broadcast Channel through downlink physical control channel, and definite needs of Physical Downlink Control Channel position are known the quantity information of downlink physical mixed retransfer channel; The quantity information of downlink physical mixed retransfer channel is relevant with the up-downgoing proportionate relationship again; And the up-downgoing proportionate relationship obtains from Dynamic Broadcast Channel again, and this has just produced a deadlock problem, and the information that makes all can't obtain.
Put forward another kind of solution is to be placed on Physical Broadcast Channel P-BCH (Physical Broadcast Channel) to go up transmission for this reason; But in realizing process of the present invention; The inventor finds that this coding that will cause the P-BCH of TDD system and FDD system, modulation and mapping are all different, and this will increase the complexity of P-BCH demodulation.
