Description
Technical field
The present invention relates to wireless communication field, relate in particular to and realize the technology that DBCH sends under a kind of TDD mode.
Background technology
TDD (Time Division Duplex, time division duplex) pattern is a kind of pattern of carrying out wireless transmission in wireless channel, realizes by periodic TDMA (time division multiple access) frame structure that repeats in time domain.Under tdd mode, transmit and receive is that timesharing is carried out, make that based on the wireless transmission method of tdd mode the up-downgoing channel can time division multiplexing, frame structure under the tdd mode can be divided into several time slots again, time slot allocation between Uplink/Downlink can be by a transfer point change flexibly, to satisfy different business demands.
Frame structure under the tdd mode as shown in Figure 1; among the figure: the field that it is 5ms that each frame comprises 2 length; every field comprises 8 time slots (slot); the length of each time slot is 0.5ms; every field also comprises three special time slot: DwPTS (Downlink Pilot Time Slot; descending pilot frequency time slot), GP (GuardPeriod; protect time slot) and UpPTS (Uplink Pilot Time Slot; uplink pilot time slot); these three special time slot DwPTS; the length summation of GP and UpPTS is 1ms, and wherein the length of DwPTS and UpPTS is configurable.As we know from the figure, comprising DwPTS in subframe 1 and the subframe 6, GP and UpPTS, other descending sub frames are made up of 2 time slots.
Wherein subframe 0, and subframe 5 and DwPTS be downlink transfer always; In the change-over period the inside of 5ms, UpPTS, subframe 2 and subframe 7 all are uplink; In the change-over period the inside of 10ms, GP and UpPTS only exist only in first field the inside, are 1ms second field the inside DwPTS length, UpPTS and subframe 2 uplink always, and subframe 7, subframe 8, subframe 9 all are downlink transfer.
Under existing TDD mode of operation, a control channel all can be arranged in each descending sub frame, this control channel can provide the frequency domain resource of this descending sub frame and distribute indication, and acquiescence is current whole descending sub frame on the time domain.Wherein DBCH (Dynamic Broadcast Channel, Dynamic Broadcast Channel) sends on subframe 5, can indicate the time length of field of DwPTS and UpPTS among the DBCH here.The concrete time-frequency domain position that sends of DBCH is to be indicated by the DL grant of DBCH (the control signaling of scheduling downlink resource indication), wherein the DL grant of DBCH sends on the control channel of subframe 5, user side parses the DL grant of DBCH according to this control channel, from DL grant, just know frequency domain position and time-domain position that DBCH takies in subframe 5 like this, just can solve the particular content of DBCH then.
Because in the transmission of actual frame, GP can and become big along with the radius of society increase, and the DwPTS+GP+UpPTS length overall is 1ms, if GP changes, DwPTS just may change so, and the size that is to say DwPTS is variable.Like this, carry out the words of combined dispatching when the subframe 5 of DwPTS and front, only on subframe 5, there is control channel, and the DwPTS the inside does not have control channel, so after the control channel on subframe 5 solves the DL grant of DBCH, this DL grant can only indicate the frequency domain position of this DBCH, and be defaulted as the time length of field sum of subframe 5 and DwPTS on the time-domain position, so only obtained DwPTS the time length of field after, just can parse the particular content of DBCH, and the time length of field of DwPTS is to indicate in the particular content of DBCH.So just produced contradiction,, caused normally connecting system of user, influenced the operate as normal of system so that user side can't parse the particular content of DBCH.
In sum, in realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art: according to the DBCH delivery plan under the existing TDD pattern, might make user side can't proper solution separate out the particular content of DBCH, cause normally connecting system of user, influenced the operate as normal of system.

Embodiment
Embodiment of the present invention provides and has realized method and the device that DBCH sends under a kind of TDD mode.For better describing embodiment of the present invention, now in conjunction with the accompanying drawings the specific embodiment of the present invention is described, be illustrated in figure 2 as a schematic flow sheet of the described method of embodiment of the present invention, described method comprises:
Step 11: set in advance the field that includes the shared time domain length information of indication DBCH.
Specifically, be exactly before Dynamic Broadcast Channel DBCH sends, at first in the scheduling downlink resource indication control signaling DL of DBCH grant or among the main broadcast channel PBCH, set in advance the field that includes the shared time domain length information of indication DBCH.The above-described field that sets in advance also can be arranged in other signalings beyond the DBCH, only otherwise be included among the DBCH and just can meet the demands.User side just can not rely on the indication of DBCH particular content like this, and directly just can draw the shared time length of field of DBCH according to the field that sets in advance, thereby carries out follow-up operation normally.
The above-described method that sets in advance the field that includes the shared time domain length information of indication DBCH, can realize in the following way: the field that sets in advance the concrete time domain length information that includes descending pilot frequency time slot DwPTS, so just can draw the shared time domain length information of DBCH according to the concrete time domain length information of described DwPTS and the time domain length information of DBCH place subframe.
The time domain length information of DBCH place subframe described here can be known in advance, in general under tdd mode, DBCH sends on the subframe 5 in the tdd frame structure, the subframe that is to say the DBCH place is a subframe 5, the time length of field of DBCH place subframe is exactly the time length of field of subframe 5 like this, and the time length of field of subframe 5 is known, so when DwPTS and subframe 5 are carried out combined dispatching, the summation of length of field when length of field and subframe 5 when the shared time length of field of DBCH is exactly DwPTS concrete.
For instance, increase length of field when a field being set indicating DwPTS concrete in the DL of DBCH grant, length of field is 0.5ms during the DwPTS of this field indication concrete.When DBCH sends on subframe 5, at first from the control channel of subframe 5, parse the DL grant of DBCH, this DLgrant can indicate the frequency location information of this DBCH, length of field during indicated DwPTS concrete in the field that simultaneously also can obtain to increase; Because the time length of field of subframe 5 is known, be assumed to 1ms, so according to the concrete time domain length information of DwPTS and the time domain length information of subframe 5, just can obtain the shared time length of field of DBCH, just length of field adds the time length of field of subframe 5 during DwPTS concrete, and promptly 1.5ms is exactly the shared time length of field of DBCH.
The above field that increases setting also can be in main broadcast channel PBCH, just can meet the demands so long as in other signalings beyond the DBCH this field is set.
In addition, the method that the above sets in advance the field that includes the shared time domain length information of indication DBCH can also obtain by following mode: set in advance the indication information that includes descending pilot frequency time slot DwPTS, protection time slot GP and these three kinds of special time slot length combination of uplink pilot time slot UpPTS; According to described indication information and three kinds of special time slot length combination relations that set in advance, obtain the concrete time domain length information of DwPTS again; Just can draw the shared time domain length information of DBCH then according to the concrete time domain length information of described DwPTS and the time domain length information of DBCH place subframe.
Wherein, more than the relation of three kinds of special time slot length combination can be predisposed to the form of correspondence table, and this correspondence table is stored on the receiving device; Also it can be predisposed to other forms of corresponding relation, and this corresponding relation is left in the independent database module, in needs, directly call.
For instance, increase is provided with the combination that a field is indicated three kinds of special time slot length in main broadcast channel PBCH, and indication information described here can be regarded the corresponding informance of three kinds of special time slot length combination relations of indication as.Before DBCH sends on subframe 5, PBCH can at first send, just can know corresponding informance indicated in the field of this increase by resolving the PBCH that sends earlier like this, suppose that here this corresponding informance is three kinds of sequence numbers in the special time slot length combination relation table; Then according to the specified sequence number of this corresponding informance, in three kinds of special time slot length combination relation tables that set in advance, search, obtain the pairing three kinds of special time slot length combination of this sequence number, here suppose that this is combined as DwPTS:GP:UpPTS=0.5ms:0.25ms:0.25ms, so just can be indirect obtain DwPTS concrete the time length of field be 0.5ms; So after DBCH sends on subframe 5, because the time length of field of subframe 5 is known, here be assumed to 1ms, so just can be according to the concrete time domain length information of DwPTS and the time domain length information of subframe 5, obtain the shared time length of field of DBCH, just length of field adds the time length of field of subframe 5 during DwPTS concrete, and promptly 1.5ms is exactly the shared time length of field of DBCH.
The above field that increases setting also can be in the DL of DBCH grant, just can meet the demands so long as in other signalings beyond the DBCH this field is set.
Step 12: when DBCH sends, send the field that sets in advance and arrive user side.
Specifically, exactly after having set in advance field, when DBCH sends, this field that sets in advance is also sent to user side, user side just can obtain the shared time length of field of DBCH according to this field that sets in advance like this; Then just can according to the DBCH that is obtained shared the time length of field and in the DL of DBCH grant the frequency location information of indicated DBCH, parse the particular content of DBCH, thereby guarantee user's connecting system normally, system is worked normally.
Wherein, user side at first in the field that sets in advance, obtains the shared time length of field of DBCH; Then just can be when accessed length of field and in the DL of DBCH grant the frequency location information of indicated DBCH, parse the particular content of DBCH.The frequency location information of DBCH recited above is directly to obtain from the DL grant of DBCH, just after sending on the subframe of DBCH at the place, can parse the DL grant of DBCH from the control channel of this place subframe, this DL grant will indicate the frequency location information of this DBCH.According to this frequency location information and the shared time domain length information of DBCH that is obtained, just the particular content of this DBCH can have been parsed like this.
