The realization method that radio frames or the information of field are carried in system broadcast message is referred to above-mentioned base station side method Description.
No matter the carrying mode of the information of which kind of radio frames or field, the particular content of the information of radio frames or field also has It is a variety of.The specific description for being referred to base station side embodiment of the method.
For example, the number of the radio frames or field where special subframe structure can be determined by following formula：
FN mod N=M
Wherein, FN is radio frames or the number of field, and N is the repetition week of radio frames or field where special subframe structure Phase, M is 0 or positive integer, and M values are fixed.So, the nothing where the special subframe structure carried in above system broadcast message The information of line frame or field is the corresponding N of special subframe structure, or is special subframe structure corresponding N and M.
Based on this, special subframe structure used in different radio frame or field is determined according to the configuration information received Realization method can be：The radio frames or field where the special subframe structure are determined according to special subframe structure corresponding N and M Number；Radio frames where determining it according to the configuration information of the special subframe structure or the special subframe structure of field.Wherein, If the radio frames or half frame information where the special subframe structure carried in system broadcast message are only N, M is about definite value.
Specifically, if radio frames or the information of field where carrying each special subframe structure in system broadcast message, Special subframe used in radio frames where so determining each special subframe structure respectively according to above-mentioned processing procedure or field Structure.It, can be by if the information of the radio frames or field where carrying part special subframe structure in system broadcast message Determine special subframe structure used in these radio frames or field according to above-mentioned processing procedure, then determine remaining radio frames or Special subframe structure used in field.For example, if two kinds of special subframe structures of carrying matches confidence in system broadcast message The information of radio frames or field where breath and one of which special subframe structure, then determine these radio frames or field institute first The special subframe structure used.Then, it according to the configuration information of another the special subframe structure received, determines remaining Special subframe structure used in radio frames or field.In another example if carrying 4 kinds of special subframe structures in system broadcast message Configuration information and radio frames or field wherein where 3 kinds of special subframe structures information, and this 3 kinds of special subframe structures In the radio frames at place or the information of field, the information of radio frames or field where only a kind of special subframe structure is the spy Different subframe corresponding N and M, in addition the radio frames where two kinds of special subframe structures or the information of field are the opposite special subframe Radio frames where structure or the relative position of field.So, it is first determined then the special subframe structure is believed according to relative position Breath determines other two kinds of special subframe structures, finally determines the 4th kind of special subframe structure.
If base station side dynamic configuration special subframe structure, receive at least two special subframe knots that base station is sent The configuration information of structure can be specifically：Before receiving special subframe, the signaling that base station is sent is received, carries and works as in the signaling The configuration information of special subframe structure used in preceding radio frames, reference field, one group of radio frames or one group of field.Wherein, should Signaling can be physical layer control signaling, media access control signaling or radio resource control signaling etc..
If the signaling is physical layer control signaling, specifically, receiving base in radio frames or first subframe of field Stand send the physical down control signaling.In this way, the configuration for the various special subframe structures that base station is sent is received Information.Above-mentioned base station side embodiment of the method is referred to for information description entrained in signaling.
Below in conjunction with concrete application scene, describe in detail to method provided in an embodiment of the present invention.
A kind of existing LTE-TDD systems medium and small interval clock synchronization scheme is based on the air interface synchronization side monitored between network Case.
In LTE versions 9（LTE Rel-9）To time division duplex Home eNodeB（TDD Home eNB）Research in, propose one Air interface synchronization technical solution (3GPP TR36.922) of the kind suitable for the base stations TDD.Its main thought is：The master of air interface synchronization is same Walk cell-of-origin（The cell under MeNB in Fig. 3）Configure a kind of special subframe that GP is shorter（As shown in figure 3, MeNB is configured to spy Different sub-frame configuration 4）.The Target cell to be synchronized of time synchronization is directly acquired from main synchronous cell-of-origin（Under HeNB1 in Fig. 3 Cell）Configure a kind of relatively large special subframes of GP（As shown in figure 3, HeNB1 is configured to special subframe configuration 1）, in this way, Several OFDM symbols are gone before Target cell to be synchronized can be vacated more in the GP of its special subframe relative synchronization the cell-of-origin The reference signals such as the CRS of main synchronous cell-of-origin are detected to obtain time synchronization.Similarly, it cannot directly be obtained from main synchronous cell-of-origin Take the object synchronization cell to be synchronized of time synchronization（The cell under HeNB2 in Fig. 3）Special son of the GP configuring with respect to bigger Frame（It is set to 0 as shown in figure 3, the special subframe of HeNB2 configurations is matched）, in this way, Target cell to be synchronized can be in its special son Several OFDM symbols go the reference signals such as detection CRS to obtain synchronization before being vacated relative to synchronized cells in the GP of frame more.
As it can be seen that in air interface synchronization scheme, it is desirable that base station to be synchronized configures longer GP and goes to receive what synchronous source base station was sent Downlink signal is to obtain synchronization.Since special subframe structure in existing LTE-TDD frame structures is once configure, all radio frames are all Using identical GP length, and actually base station air interface synchronization does not need to base station to be synchronized and is monitored in each radio frames together Walk the downlink signal of source base station.Therefore, it is based on existing system to design, to implement the air interface synchronization side based on TDD special subframes Case then requires base station to be synchronized to distribute longer GP time slots in all radio frames, since GP time slots are unable to transmitting physical signal, Therefore the expense of system is significantly increased, system effectiveness is reduced.
By taking the HeNB1 in Fig. 3 as an example, using method provided in an embodiment of the present invention, HeNB1 is respectively to need to carry out base station Between eat dishes without rice or wine the radio frames monitored and the radio frames for eating dishes without rice or wine between base station to monitor configuration special subframe structure need not be carried out.Wherein, Need carry out base station between eat dishes without rice or wine monitor radio frames used in special subframe structure GP length be more than need not carry out base station Between eat dishes without rice or wine monitor radio frames used in special subframe structure GP length.
Preferably, the radio frames monitored and need not carry out eating dishes without rice or wine between base station to monitor to need to carry out to eat dishes without rice or wine between base station A special subframe structure is respectively configured in radio frames.So, it needs to carry out to eat dishes without rice or wine between base station special used in the radio frames monitored Different subframe structure is known as special subframe structure one, need not carry out special subframe used in the radio frames monitored of eating dishes without rice or wine between base station Structure is known as special subframe structure two.
It is of course also possible to according to communication requirement, respectively need to carry out to eat dishes without rice or wine between base station the radio frames monitored and to be not required to Multiple special subframe structures are respectively configured in the radio frames for carrying out eating dishes without rice or wine to monitor between base station.
Since base station between carrying out base station when eating dishes without rice or wine to monitor, relatively long GP is needed to configure, so as to what is had more in GP It carries out eating dishes without rice or wine to monitor on OFDM symbol.Eat dishes without rice or wine to monitor between base station be carry out in the period, then, by need to carry out It eats dishes without rice or wine the radio frames monitored or field and the radio frames for eating dishes without rice or wine between base station to monitor or field configuration need not be carried out not between base station Same special subframe structure so that when base station carries out eating dishes without rice or wine to monitor, using longer GP, when without eating dishes without rice or wine to monitor, Using shorter GP to transmit signal, to improve system effectiveness, overhead is reduced.
If it is static or be semi-statically configured need to carry out base station between eat dishes without rice or wine special subframe knot used in the radio frames monitored Structure one and special subframe structure two used in the radio frames for eating dishes without rice or wine between base station to monitor need not be carried out, and per N number of radio frames It carries out eating dishes without rice or wine to monitor between a base station.So, need carry out base station between eat dishes without rice or wine monitor radio frames System Frame Number（SFN）It can be with It is determined by formula F SN mod N=M.
HeNB1 sends the configuration information of special subframe structure one in system broadcast message, special subframe structure two is matched Confidence ceases and the value of N.Optionally, the value of M is also carried in system broadcast message.If not having to carry M's in system broadcast message Value, the then value for the M that makes an appointment with terminal.
Specifically, can be in system broadcast message（Such as system information block SIB1）Defined in new field, for carrying Above-mentioned all information.So, the field of the carrying special subframe structure configuration defined in original agreement can be carried no longer special The configuration information of subframe structure.The field of carrying special subframe structure configuration defined in original agreement can also continue to carry special The configuration information of different subframe structure, is known as special subframe structure three by the corresponding special subframe structure of the field.In this case, During the mobility measurements of terminal, communicated with terminal using special subframe structure three.It is empty between needing progress base station When mouthful monitoring, using special subframe structure one, special subframe structure two is used on remaining is wireless town.
It can also be in system broadcast message（Such as SIB1）Defined in new field, for carrying special subframe structure one The value of configuration information and N.If sending the value of M, also carry in the field.Carrying special subframe defined in original agreement The field of structure configuration carries the configuration information of special subframe structure two.In this case, it is needing to carry out to eat dishes without rice or wine to supervise between base station When listening, using special subframe structure one, special subframe structure two is used on remaining is wireless town.
Terminal receive HeNB1 send system broadcast message, therefrom obtain special subframe structure configuration information and other Information.
Specifically, if carrying the configuration information of special subframe structure one, special subframe knot in the field of above-mentioned new definition The configuration information of structure two and the value of N optionally also carry the value of M.Terminal obtains these information from the field newly defined, according to N and M determines the SFN of radio frames, and according to the configuration information of special subframe structure one, determines the corresponding radio frames institutes of these SFN The special subframe structure one used.If it is special that the field of the carrying special subframe structure configuration defined in original agreement also carries The configuration information of subframe structure three, it is determined that special subframe structure three used in the corresponding radio frames of mobility measurements process, Determine special subframe structure two used in remaining radio frames；If the carrying special subframe structure configuration defined in original agreement Field no longer carry information, it is determined that special subframe structure used in the radio frames except the corresponding radio frames of above-mentioned SFN Two.
If special subframe structure used in dynamic configuration radio frames, and it is empty between base station of progress per N number of radio frames Mouth is monitored.So, need carry out base station between eat dishes without rice or wine monitor radio frames System Frame Number（SFN）Formula F SN mod can be passed through N=M is determined.
Before special subframes of the HeNB1 on sending radio frames, signaling is sent to terminal, where carrying it in the signaling Special subframe structure used in current radio frames, or carry special subframe structure used in one group of radio frames match confidence Breath.This group of radio frames can be include current radio frames where the signaling and follow-up continuous or discontinuous multiple wireless Frame can also be continuous or discontinuous multiple radio frames after current subframe where the signaling.In addition, this group of radio frames can Can also be different wireless of used special subframe structure to be the identical radio frames of used special subframe structure Frame.
By taking physical layer control signaling as an example, HeNB1 it is each need carry out base station between eat dishes without rice or wine monitor radio frames first In a subframe, physical layer control signaling is sent to terminal, the configuration of special subframe structure one is carried in the physical layer control signaling Information.Or the physical layer sent in first subframe for carrying out eating dishes without rice or wine the radio frames monitored between base station is needed to control letter first The value of the configuration information and N of special subframe configuration one is carried in order, optionally, also carries the value of M.Further, if it is original The field of carrying special subframe structure configuration defined in agreement no longer carries information, then HeNB1 is between it need not carry out base station It eats dishes without rice or wine in first subframe of the radio frames monitored, sends physical layer control signaling to terminal, taken in the physical layer control signaling Configuration information with special subframe used in this radio frames or one group of radio frames；Certainly, if you do not need to dynamic configuration these The special subframe structure of radio frames can also send the configuration information of special subframe structure two by system broadcast message.As it can be seen that Dynamic special subframe configures and the configuration of advance special subframe can be used in combination.If the special son of carrying defined in original agreement The field of frame structure configuration still carries the configuration information of special subframe structure, then HeNB1 can carry special son in the field The configuration information of frame structure two.
Before receiving special subframe, terminal receives the above-mentioned signaling that HeNB1 is sent, and therefrom obtains special subframe structure Configuration information.
Specifically, if carrying the configuration information of special subframe structure one or the configuration of special subframe structure two in the signaling Information, terminal determine special subframe structure used in the radio frames.If the carrying special subframe knot defined in original agreement The field of structure configuration also carries the configuration information of special subframe structure, the then configuration of the special subframe structure carried according to the field Information determines special subframe structure used in the corresponding radio frames of mobility measurements process.
