Description
Technical field
The present invention relates to the communications field, the collocation method and the communication system of physical resource in a kind of communication system.
Background technology
In the wireless communication system, the base station is to point to the equipment that the terminal provides functions such as initial access, professional transmission and resource management, and usually, above-mentioned functions is realized through control channel and administrative messag in the base station.The base station communicates through Uplink/Downlink and terminal, and down link is meant the Radio Link of base station to the terminal, and up link refers to the Radio Link of terminal to base station.
OFDM (Orthogonal Frequency Division Multiplexing abbreviates OFDM as) technology is the high speed transmission technology under a kind of wireless environment, and its pulse duration through escape character improves the performance of anti-multipath decline.The realization principle of OFDM technology is: high-speed serial data is transformed into the parallel data of the relative low speed of multichannel, and this multidiameter delay data-modulated is transmitted to mutually orthogonal subcarrier.It is on the basis of OFDM technology that OFDM inserts (Orthogonal Frequency Division Multiple Access abbreviates OFDMA as) technology, through making the CU different subcarriers, realizes that multiple access inserts.In the wireless communication system of OFDMA technology, accomplish the mapping and the wireless resource allocation of Radio Resource by the base station.For example; System configuration when the system configuration when confirming the base station to the downlink transfer at terminal and the uplink of resource allocation information and terminal to base station and resource allocation information etc. by the base station; The base station disposes and resource allocation information to the terminal transmitting system through control channel; The terminal receives these information on the control channel of confirming, and then receives and the transmission data, communicates with the base station.
In addition, in order to adapt to various channel conditions, a kind of wireless communication system has kinds of frame, how under the condition of kinds of frame, to guarantee the consistency of the design of control channel, comprises whether the resource location, the resource quantity that are used to transmit control channel be consistent; In the same generation communication standard, the plurality of communication systems coexistence, the control channel that how to design separately is also extremely important to guarantee that each communication system can coexist; And; A communication system need continue to support its system, for example usually in last generation in evolution system in evolution; IEEE 802.16m system is the evolution system of IEEE 802.16e system; And IEEE 802.16e is last generation system of IEEE802.16m, therefore, supports last generation system also to limit the method for designing of evolution system control channel.
WiMax (Worldwide Interoperability for Microwave Access), promptly worldwide interoperability for microwave inserts.Another name of WiMAX is 802.16.WiMAX is an emerging wireless access wide band technology, can provide towards the high speed of the Internet to connect.Wherein, IEEE 802.16e is the standard that mobile broadband wireless inserts, and Wimax 16e system is meant the communication system based on IEEE 802.16e standard.The Wimax communication system can be divided into PUSC (Partial Usage of Sub-Channel, part is used subchannel) and two kinds of patterns of FUSC (Full Usage of Sub-Channel uses subchannel fully) according to the frequency band division mode.PUSC refers to frequency band is divided into 3 sectors, separately use, and FUSC is meant that frequency band is regardless of the sector, merges and uses.The resource of Wimax 16e system can have PUSC, FUSC, AMC multiple modes such as (Adaptive Modulation and Coding, Adaptive Modulation and Coding) by structure.
LTE (Long Term Evolution, Long Term Evolution) project is the evolution of 3G, starts from the Toronto meeting of 3GPP in 2004.LTE is a transition between 3G and the 4G technology, is the global standards of 3.9G, and it improves and strengthened the aerial access technology of 3G, adopts OFDM and the MIMO sole criterion as its wireless network evolution.The frame structure of LTE communication system is made up of the Frame of 10ms, and each frame has 10 sub-frame, can be divided into the field of two 5ms again, and each subframe is made up of the up symbol of some, descending symbol or time space GP.Can be divided into 5ms and 10ms according to the up-downgoing switching cycle; A kind of configuration frame structure that LTE communication system 5ms switches is as shown in Figure 1, and wherein DwPTS is a part descending in the special subframe, is used to send descending symbol; UpPTS is a part up in the special subframe; Be used to send descending symbol, GP is a special subframe empty part, does not send any signal.
Wimax communication system and LTE communication system all can be divided into time division duplex (TimeDivision Duplex abbreviates TDD as) system and FDD (Frequency DivisionDuplex abbreviates FDD as) system.In tdd systems; For wireless communication system based on OFDM or OFDMA; Its Radio Resource mapping main frame structure and resource structures according to this wireless communication system; Frame structure is described the control structure of Radio Resource on time domain, and resource structures has been described the control structure of Radio Resource on frequency domain.Frame structure is divided into Radio Resource the unit of different brackets on time domain; Like superframe (Superframe), frame (Frame), subframe (Subframe) and symbol (Symbol); Through being set, Different control channel (for example, broadcast channel, clean culture and Multicast Channel etc.) realizes scheduling controlling.Each superframe, frame, subframe and symbol all occupy the regular hour on time domain.Under the tdd mode of Wimax communication system; Downgoing time switches to line time has one period free time to be called transmission/reception change gap (Transmission/Receive Transition Gap; Be called for short TTG); Last line time switches to downgoing time has one period free time to be called reception/transmission change gap (Receive/Transmission Transition Gap is called for short TTG).Any signal is not sent in terminal and base station on the time slot of TTG and RTG.
In communication system; The center frequency point close together that the frequency band of two communication systems uses possibly occur; Interval between two frequency bands is less or be almost 0 situation; Two communication systems serious interference each other in this case, two communication systems of this situation are known as adjacent communication system frequently.As shown in Figure 2, system A and the B of system are two adjacent communication systems frequently, and system A can produce the Power leakage of frequency band, part energy are leaked on the frequency band of the B of system, to the communication generation larger interference of the B of system.Equally, the B of system also can produce A and disturb.Particularly work as the B of system and carrying out uplink communication; And the A of system is when carrying out downgoing communication at the same time; The terminal that belongs to the B of system will be to the base station upstream data, and the signal of the terminal of the B of system emission at this moment can produce on the terminal antenna of the bigger frequency band energy leakage and the A of system that is added to, to the terminal reception downstream signal generation larger interference of the A of system; That is to say the up the other side's of interfering with each other the reception signal of the descending and B of A, vice versa.During adjacent frequency coexistence when considering that two communication system are altogether stood (base station location that refers to two communication systems is in same place), above-mentioned interference problem will be more serious.

Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
When two communication systems had enough frequency domain interval on frequency band, the energy of leakage can not make a big impact to another communication system fewer; On the contrary, when the frequency domain spacing of two communication systems is little, will cause mutual interference owing to the energy leakage; Following examples of the present invention two communication systems that the frequency domain spacing is less are called adjacent communication system frequently, and with the neighbour frequently communication system be that example describes.
Embodiment 1
Fig. 3 shows the collocation method flow chart according to physical resource in a kind of communication system of the embodiment of the invention, and wherein, first communication system and second communication system are adjacent communication system frequently, and this method may further comprise the steps:
Step S302, configuration second communication system second on line time be comprised in first communication system first in the line time;
Step S304, second downgoing time of configuration second communication system is comprised in first downgoing time of first communication system.
Preferably; On first on the line time and second length difference of line time less than first designated length; The length difference of first downgoing time and second downgoing time is less than second designated length, and wherein, first designated length and second designated length can be set according to actual needs; Under the prerequisite of the related request that meets first communication system and second communication system, guarantee that length difference is as far as possible little.
When concrete the realization; Can be through on the uplink and downlink frame structure of second communication system (for example communication system B), increasing or reduce the method for up symbol (promptly going up line time) or descending symbol (being downgoing time), make communication system B up-downgoing time and first communication system (for example communication system A) the up-downgoing time unifying or be included in the up-downgoing time of communication system A.
In said process, up-downgoing symbolic number, the frame structure of first communication system need not made any change.And the second communication system only need change the up-downgoing symbolic number; Such as increasing up symbolic number; Reduce descending symbolic number simultaneously; Make in time the up-downgoing time of two systems to align, the situation that the embodiment of the invention was completely contained in up-downgoing time of second communication system in up-downgoing time of first communication system is called the up-downgoing aligned condition.As shown in Figure 4, system A is descending to send data with the B of system is up on the identical time, produced very big interference.Through after the modification to the B of system, make the downgoing time of the B of system be included in the downgoing time of the A of system, the last line time of system B is also contained in the last line time of the A of system, and interference problem is reduced greatly.
After above-mentioned first communication system and second communication system sent data according to configuration separately, its adjacent interference frequently will be less.
When present embodiment is adjacent communication system frequently in first communication system and second communication system; Be included in through the duration up and down that disposes a communication system in the duration up and down of another communication system; Solved the mutual interference problem between two adjacent communication systems frequently (the adjacent communication system frequently at station especially altogether) up-downgoing symbol; Improve the performance of communication system, and then accomplished the reliable communication of communication system.
When LTE communication system (corresponding above-mentioned communication system A) and Wimax 16e communication system (corresponding above-mentioned communication system B) adjacent frequency coexistence; There is the situation that interferes with each other; In order to reduce by two phase mutual interference between system; Can under the constant situation of LTE system, Wimax 16e system be made amendment, make it satisfy the condition of up-downgoing alignment.
The ascending-descending subframes structure of LTE has 7 kinds, is represented by numbering 0-6 respectively, like the uplink-downlink configuration table, promptly shown in the table 1; D represents descending sub frame, and length 1ms is used to send descending symbol, and U represents sub-frame of uplink; Length 1ms is used to send up symbol, and S represents special subframe; Length 1ms, also has time (DwPTS) of sending descending symbol and the blank time Gp that does not send any symbol at the time (UpPTS) of the up symbol of middle existing transmission.
UpPTS in the S subframe; The ratio of DwPTS and GP also can be adjusted, like special subframe frame allocation list, promptly shown in the table 2; UpPTS under condition of different; DwPTS can be different with the shared time of GP, and table 2 has shown the time of UpPTS and DwPTS, and because the S subframe lengths is that 1ms is exactly the time of GP with the time that 1ms deducts UpPTS and DwPTS.
Table 1
Table 2
Introduce the amended frame structure of Wimax 16e communication system according to different LTE uplink-downlink configuration and the configuration of special subframe frame below, to reach two communication system up-downgoings alignment.
Instance 1
When uplink-downlink configuration was the configuration of the 0th in the table 1, the up-downgoing ratio was DSUUUDSUUU in the correspondence table 1.
In order to reach above-mentioned up-downgoing aligned condition, when the LTE system used different special subframe S types, the up symbol and the descending symbolic number of corresponding Wimax 16e system need satisfy the condition shown in the table 3.And the 0th subframe of the corresponding LTE of the original position of Wimax frame system is as shown in Figure 5.
Table 3
Definite method of table 3 is: the up-downgoing basis time of at first confirming the Wimax system according to the uplink-downlink configuration of LTE; Like the uplink-downlink configuration of LTE is 0 to be; The descending basis time of Wimax is the time 1ms of a LTE descending sub frame, and the up basis time of Wimax is the time 3ms of three LTE sub-frame of uplink.And then dispose to confirm the up-downgoing additional period of Wimax system according to the special subframe frame of LTE; Additional period is confirmed by table 2; DwPTS in the table 2 and UpPTS are respectively downgoing time and last line times in the special subframe of LTE, this time corresponding respectively the descending additional period and the up additional period of Wimax system.For with the LTE system compatible; Line time equals up basis and the time adds up additional period on the maximum of Wimax; The maximum downstream time of Wimax equals descending basis and the time adds descending additional period, the used actual uplink time of Wimax system and downgoing time all can not surpass maximum on line time and maximum downstream time.Simultaneously; Because the Wimax communication system also has corresponding TTG and RTG time to reserve; With the smooth of up-downgoing switching of going bail for, wherein TTG can overlap with the GP time among the LTE, did not need extra consideration; RTG then needs the time of 80-100ms at least; This part time need deduct the line time on the Wimax maximum, that is to say the RTG time of line time on the Wimax maximum=up basis time+up additional period-Wimax, basis time Wimax maximum downstream time=descending+descending additional period.
Because the time that symbol of Wimax system (no matter up or descending) takies is 102.857ms, can calculates like this in certain maximum up and maximum downstream and can put down what up symbols and descending symbol in the time at most again.It is that example describes that present embodiment adopts the PUSC pattern with the Wimax communication system, and according to the relevant regulations of PUSC pattern, the descending symbolic number of Wimax need be an odd number; Up symbolic number is 3 multiple; Can obtain the parameter in the table 3 like this, show that in the LTE uplink-downlink configuration be at 0 o'clock, the Wimax system up-downgoing symbolic number under the various special subframe frame configuring conditions; The Wimax communication system has only under the PUSC pattern and satisfies this condition; The LTE communication system of could getting along well produces bigger interference, and the resource of waste is less relatively simultaneously, promptly reaches so-called adjacent frequency coexistence condition.Wherein, In the form 27 and 30 refers to up in this case symbolic number not only can get 27 but also can get 30; Reason is when the RTG of Wimax communication system gets different value, (generally to get 40ms to 140ms); Can make Wimax up maximum time different, the number of symbols that makes it possible to hold is different.
For the Wimax communication system that adopts the FUSC pattern; Its account form and PUSC mode class are seemingly; But need not satisfy descending symbolic number must be odd number, and up symbolic number must be the condition of 3 multiple, and the up-downgoing symbolic number can dispose more neatly; Make that the utilance of resource is higher on time domain, here explanation no longer one by one.The Wimax16e system can have polytype resources such as PUSC, FUSC, AMC simultaneously in some cases, and the up-downgoing symbol need not satisfy above-mentioned condition yet like this, can flexible configuration, also explanation no longer one by one here.
As a same reason, when the uplink-downlink configuration of LTE system is 1,2, also use said method to calculate the up-downgoing number of symbols of Wimax communication system under the PUSC pattern, like table 4, table 5 in the instance 2,3, method is the same, below gives unnecessary details no longer one by one.
LTE and Wimax 16e alignment in time are as shown in Figure 5; Represent Wimax 16e system with 16e among Fig. 5; The 0th sub-frame (being the descending starting position of LTE) of the corresponding LTE of the original position of Wimax 16e system system; The 5th sub-frame of the corresponding LTE of the original position of the next frame of Wimax 16e system (i.e. figure in second frame) system, thus reached the up-downgoing aligned condition of front.Wherein, the x among Fig. 5 represents the descending symbolic number of Wimax 16e, and the value in the correspondence table 3 possibly be 11,15 or 17, and the y among the figure represents the up symbolic number of Wimax 16e, and the value in the correspondence table 3 possibly be 27 or 30.The meaning of x and y is also similar with present embodiment among the embodiment afterwards, repeats no more later on.Need to prove that it is that symbolic number can be 27 or 30 in this case that 27 or 30 the meaning is filled in some place in the table 3, one of them can be selected flexibly according to the needs of network configuration by system.
When uplink-downlink configuration was 1, the up-downgoing ratio was DSUUDDSUUD in the correspondence table 1.1.In order to reach above-mentioned up-downgoing aligned condition, when the LTE system used different special subframe S types, the up symbol and the descending symbolic number of corresponding Wimax 16e system need satisfy the condition shown in the table 4.And the 9th subframe of the corresponding LTE of the original position of Wimax frame system is as shown in Figure 6.
Table 4
LTE and Wimax 16e alignment in time are as shown in Figure 6; Represent Wimax 16e system with 16e among the figure; The 9th sub-frame (being the descending starting position of LTE) of a last frame of the corresponding LTE of the original position of Wimax 16e system system; The 4th sub-frame of the corresponding LTE of the original position system of the next frame of Wimax 16e system (i.e. second frame among the figure), thus reached foregoing up-downgoing aligned condition.
When uplink-downlink configuration was 2, the up-downgoing ratio was DSUDDDSUDD in the correspondence table 1.1.
In order to reach above-mentioned up-downgoing aligned condition, when the LTE system used different special subframe S types, the up symbol and the descending symbolic number of corresponding Wimax 16e system need satisfy the condition shown in the table 5.And the 8th subframe of the corresponding LTE of the original position of Wimax frame system is as shown in Figure 7.
Table 5
LTE and Wimax 16e alignment in time are as shown in Figure 7; Represent Wimax 16e system with 16e among Fig. 7; The 8th sub-frame (being the descending starting position of LTE) of a last frame of the corresponding LTE of the original position of Wimax 16e system system; The 3rd sub-frame of the corresponding LTE of the original position system of the next frame of Wimax 16e system (i.e. second frame among the figure), thus reached foregoing up-downgoing aligned condition.
The up-downgoing symbol numbers that present embodiment is provided with Wimax 16e system through uplink-downlink configuration and the configuration of special subframe frame according to the LTE system; Make the LTE system and the Wimax 16e system of adjacent frequency coexistence can arrive up-downgoing time unifying recited above, thereby reduce the interference between system.
The value of up-downgoing symbolic number is an optimal value among the Wimax 16e among the table 3-5 of above instance 1-3, when reality realizes, can satisfy simultaneously among the table 3-5 with the up-downgoing symbolic number in the delegation, satisfies one and also can.For example, for table 5, when the special subframe frame was configured to the 0th configuration, the value of up symbolic number can be 31 among the Wimax 16e, and the value of descending symbolic number need not be 9, also can be less than 9.
Adjacent frequently when depositing as communication system A and communication system B, if the uplink-downlink configuration of the A of system or special subframe configuration change, will have influence on the up-downgoing alignment of it and B system, thereby make very little interference originally become very big again.In order to address this problem; When the A system changes its uplink-downlink configuration or the configuration of special subframe frame; Need be to sending ConfigChange (configuration change) signaling with the base station of the system B of its coexistence; Coming into force constantly of uplink-downlink configuration after the base station of reporting system B changes, the configuration of special subframe frame and this variation, Notification Method can be through core net or wireless network.
The base station of system B is after receiving the ConfigChange signaling; According to the content choice of ConfigChange signaling can with self uplink-downlink configuration of new system A uplink-downlink configuration and special subframe frame configuration alignment; And constantly bring into use new uplink-downlink configuration coming into force, make that the up-downgoing of etching system A and the B of system still can be alignd when coming into force.That is to say reporting system B when the A of system prepares to change uplink-downlink configuration, the system B of making also changes the uplink-downlink configuration of self, guarantees that finally the up-downgoing of two systems still can be alignd.
Said system A can send the ConfigChange signaling through core net, and the base station of reporting system B makes the base station of the B of system learn the information such as uplink-downlink configuration that the A of system uses.
Wherein, system A can be the LTE communication system, and system B can be a Wimax 16e communication system, and the uplink-downlink configuration of system A and special subframe frame dispose the uplink-downlink configuration of pairing system B can reference example 1,2,3.
The configuration of system A is only chosen wherein several kinds in the various configurations in instance 1,2,3 as a set, and the uplink-downlink configuration of the corresponding B of system also has only several kinds of optional configurations of several kinds and the A of system corresponding one by one.For example, if the A of system is the LTE system, system B is the Wimax system, if the A of system only supports two kinds of configurations: configuration 1:LTE uplink-downlink configuration is 0, and the special subframe frame is configured to 0; Configuration 2:LTE uplink-downlink configuration is 1, and the special subframe frame is configured to 8, and two kinds of configurations can only supporting of the B of system are so: configuration 1: descending 11 symbols, up 27 symbols; Configuration 2: descending 27 symbols, up 18 symbols.
Present embodiment is considered because adjacent bandwidth leaks the problem that causes adjacent system frequently to interfere with each other; Adopt to increase or reduce the method for line time on some communication systems or downgoing time; Solved the problem that interferes with each other; Ensure that terminal and base station can normal communications, guaranteed the spectrum efficiency of wireless communication system.Simultaneously, in the time of can changing in the uplink-downlink configuration of a system, the configuration of another system can also be adjusted accordingly, two systems is remained disturb less state.
