Description

Frame collocation method, signaling method and system during a kind of coexistence of communication systems

Technical field

The present invention relates to the communications field, in particular to frame collocation method during a kind of coexistence of communication systems, signaling method and corresponding system.

Background technology

In wireless communication system, base station points to the equipment that terminal provides the functions such as initial access, business transmission and resource management, and usually, base station realizes above-mentioned functions by control channel and administrative messag.Base station is communicated with terminal by Uplink/Downlink, and down link refers to that the wireless link of terminal is arrived in base station, and up link refers to the wireless link of terminal to base station.

OFDM (Orthogonal Frequency Division Multiplexing, referred to as OFDM) technology is the high speed transmission technology under a kind of wireless environment, and it improves the performance of anti-multipath fading by the pulse duration of escape character.The principle that realizes of OFDM technology is: parallel data high-speed serial data being transformed into multichannel relative low speeds, and is transmitted to mutually orthogonal subcarrier by this multidiameter delay Data Modulation.Orthogonal frequency-time multiple access (Orthogonal Frequency Division MultipleAccess, referred to as OFDMA) technology is on the basis of OFDM technology, by the subcarrier making CU different, realizes multiple access access.In the wireless communication system adopting OFDMA technology, complete the mapping of Radio Resource and the distribution of Radio Resource by base station.Such as, determine that base station is to the system configuration and resource allocation information the etc. during uplink of the system configuration during downlink transfer of terminal and resource allocation information and terminal to base station by base station, base station is configured and resource allocation information to terminal transmitting system by control channel, terminal receives these information on the control channel determined, and then receive and send data, communicate with base station.In order to keep base station and the terminal Timing Synchronization when communicating, base station needs to send synchronizing signal in descender region to terminal, is called as preamble, leading or synchronizing sequence in the communication standard had.

In addition, in order to adapt to various channel condition, a kind of wireless communication system has kinds of frame, under the condition of kinds of frame, how to ensure the consistency of the design of control channel, comprise the resource location for transmitting control channel, whether number of resources is consistent; In the same generation communication standard, plurality of communication systems coexists, and how to design respective control channel also extremely important to ensure that each communication system can coexist; And, a communication system is in evolution, usual needs continue to support its system in evolution system in last generation, such as, IEEE 802.16m system is the evolution system of IEEE 802.16e system, and IEEE 802.16e is last generation system of IEEE 802.16m, therefore, support that last generation system also limit the method for designing of evolution system control channel.

Wimax 16e (Worldwide Interoperability for Microwave Access), i.e. worldwide interoperability for microwave access.Another name of Wimax 16e is 802.16.Wimax 16e is an emerging wireless access wide band technology, and the high speed of Internet can be provided to connect.Wherein, IEEE 802.16e is the standard of mobile broadband wireless access, and Wimax 16e system refers to the communication system based on IEEE 802.16e standard.Wimax 16e communication system can be divided into PUSC (Partial Usage ofSub-Channel according to frequency band division mode, part uses subchannel) and FUSC (Full Usage ofSub-Channel, uses subchannel completely) two kinds of patterns.PUSC refers to and frequency band is divided into 3 sectors, separately use, and FUSC refers to that frequency band is regardless of sector, merges and uses.The resource of Wimax 16e system can have the various ways such as PUSC, FUSC, AMC (Adaptive Modulation and Coding, Adaptive Modulation and Coding) by structure.Wherein AMC mode can have various modes, comprises the 4 kinds of structures altogether time domain accounting for 1,2,3,6 symbol.

For Wimax 16e system descender must have leading (Preamble) of a symbol and the PUSC resource in units of 2 symbols, this part PUSC resource is used for transmitting system control signal, remaining part can be made up of one or more of the various Resource Block such as PUSC, FUSC, AMC, and namely downlink resource must have leading and PUSC resource.The one namely in the up PUSC of having and AMC for ascender, is made up of one or both in PUSC and AMC, as long as just can work.

LTE (LongTermEvolution, 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 4G technology, is the global standards of 3.9G, and it improves and enhances the aerial access technology of 3G, adopts OFDM and MIMO as the sole criterion of its wireless network evolution.The frame structure of LTE communication system is made up of the Frame of 10ms, and each frame has 10 subframes, can be divided into again the field of two 5ms, and each subframe is made up of the uplink symbol of some, downlink symbol or portable protective gaps (GP).5ms and 10ms can be divided into according to up-downgoing switching cycle.

A kind of frame structure that LTE communication system 10ms switches as shown in Figure 1A, in a frame (being called LTE frame in literary composition) of duration 10ms, there is a special subframe S, wherein descending pilot frequency time slot (DwPTS) is part descending in special subframe, for sending downlink symbol, uplink pilot time slot (UpPTS) is part up in special subframe, for sending downstream signal, GP is special subframe empty part, does not send any signal.In the application, all descending sub frames and DwPTS constitute the descender region in LTE frame, and all sub-frame of uplink and UpPTS constitute the up region of LTE frame.

LTE communication system with 5ms be the configuration frame structure of switching cycle as shown in Figure 1B, the frame structure switched with 10ms unlike, every 5ms duration just has a special subframe S, has 2 special subframe S in a radio frames of duration 10ms.

OFDM symbol for LTE system has two types, and one is conventional cyclic prefix, and one is general cyclic prefix, and two kinds of symbols length is in time different.

Wimax 16e communication system and LTE communication system all can be divided into time division duplex (Time DivisionDuplex, referred to as TDD) system and Frequency Division Duplexing (FDD) (Frequency Division Duplex, referred to as FDD) system.In tdd systems, for the wireless communication system based on OFDM or OFDMA, its Radio Resource maps frame structure and the resource structures of this wireless communication system of Main Basis, frame structure describes the control structure of Radio Resource in time domain, and resource structures describes the control structure of Radio Resource on frequency domain.Radio Resource is divided into the unit of different brackets by frame structure in time domain, as frame (Superframe), frame (Frame), subframe (Subframe) and symbol (Symbol), scheduling controlling is realized by arranging different control channels (such as, broadcast channel, clean culture and Multicast Channel etc.).Each frame, frame, subframe and symbol all occupy the regular hour in time domain.Under the tdd mode of Wimax 16e communication system, as shown in Figure 2, the frame length of a Wimax 16e frame is 5ms, comprise descender region, up region, one period of free time between descender region and up region, be called sending/receiving change gap (Transmission/Receive Transition Gap, be called for short TTG), and one period of free time between up region and descender region, be called reception/transmission change gap (Receive/TransmissionTransitionGap is called for short RTG).On the time slot of TTG and RTG, terminal and base station do not send any signal.

In communication system, the center frequency point close together of the frequency band that two communication systems use may be there is, interval between two frequency bands less or be almost 0 situation, two communication systems may serious interference each other in this case, and two communication systems of this situation are referred to as adjacent frequency communication system.As shown in Figure 3, first communication system and second communication system are two adjacent frequency communication systems, first communication system can produce the Power leakage of frequency band, part energy is leaked on the frequency band of second communication system, produces larger interference to the communication of second communication system.Equally, second communication system also can produce interference to A.Particularly when second communication system is carrying out uplink communication, and the first communication system is when carrying out downgoing communication at the same time, the terminal belonging to second communication system will send upstream data to base station, at this moment the signal that the terminal of second communication system sends can produce larger frequency band energy and leaks and be added on the terminal antenna of the first communication system, downstream signal is received to the terminal of the first communication system and produces larger interference, that is the downstream signal of the first communication system and the upward signal of second communication system can interfere with each other the reception of the other side to signal, and vice versa.During adjacent frequency coexistence when considering two communication system co-sited (referring to the base station location of two communication systems in same place), above-mentioned interference problem will be more serious.

Embodiment

Hereafter will be described in detail to embodiments of the invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.

Embodiment one

In the present embodiment, first communication system and second communication system adjacent frequency coexistence and adopt tdd mode, first communication system does not need to make any change, needs to be configured according to the physical resource of frame configuration information to second communication system-frame of the first communication system, comprising:

The relevant parameter of the descender region of configuration second communication system-frame, makes the descender region of second communication system-frame be comprised in the descender region of the first communication system in time domain;

The relevant parameter in the up region of configuration second communication system-frame, makes the up region of second communication system-frame be comprised in time domain in the up region of the first communication system.

Particularly, can be configured by the physical resource of frame configuration information to this base station of the first communication system base station according to the second communication system base-station of adjacent frequency coexistence and clock synchronous, if desired frame structure be modified.This configuration can be static configuration, or, also can be that non-static configuration is as semi-static configuration or dynamic-configuration.

Above-mentioned " involved in time domain " comprises two regions situation completely overlapping in time domain.

In order to meet the inclusion relation in above-mentioned time domain, the difference of the duration in the up region of two communication system frames should be less than the first appointment duration, the difference of the duration of the descender region of two communication system frames should be less than the second appointment duration, first specifies duration and second to specify duration to be more than or equal to 0, under the prerequisite of related request meeting the first communication system and second communication system, the difference of this duration should be as far as possible little.During specific implementation, the requirement of above-mentioned duration can be reached by the adjustment of the number to the uplink symbol in second communication system-frame and downlink symbol, such as can increase uplink symbol number, reduce downlink symbol number simultaneously.

In order to meet the inclusion relation in above-mentioned time domain, also need to be configured the up region of two communication system frames and the relative position of descender region, as configured the shift time etc. of original position relative to the original position of the first communication system frame of second communication system-frame.

After having configured, second communication system base-station is when descender region sends downstream signal, and the first communication system base station coexisted with its field can not send upward signal; Second communication system base-station is when up region sends upward signal, and the first communication system base station coexisted with its field can not send downstream signal.Therefore adjacent frequency interference will be less.As shown in Figure 4, before adopting the present embodiment method, there is overlap in the descender region of the first communication system and the up region of second communication system, can send data simultaneously, create very large interference.After the amendment to second communication system, the descender region of second communication system-frame is made to be included in the descender region of the first communication system frame in time domain, the up region of second communication system-frame is also contained in the up region of the first communication system frame in time domain, and interference problem is greatly reduced.

Embodiment two

The present embodiment is based on embodiment one, and the first communication system is the LTE system adopting tdd mode, comprises the follow-up evolution system of LTE, as LTE-Advance etc.; Second communication system is the Wimax 16e system adopting tdd mode.When this LTE system and Wimax 16e system adjacent frequency coexistence, existence interferes with each other.

The uplink-downlink configuration of LTE has 7 kinds, is numbered 0-6, is designated as 0# uplink-downlink configuration ~ 6# uplink-downlink configuration.In following uplink-downlink configuration table (table 1), D represents descending sub frame, and length is 1ms, for sending downstream signal; U represents sub-frame of uplink, and length is 1ms, for sending upward signal; S represents special subframe, length 1ms, comprises again descending pilot frequency time slot (DwPTS) successively, protection interval (Gp) and uplink pilot time slot (UpPTS).Wherein, all sub-frame of uplink in LTE frame and UpPTS constitute the up region of LTE frame, and all descending sub frames in TE frame and DwPTS constitute the descender region of LTE frame.

Table 1

As can be seen from Table 1, the up-downgoing switching cycle of 0#, 1#, 2#, 3# and 6# uplink-downlink configuration is 5ms, and two field structure are identical, includes a special subframe.The up-downgoing switching cycle of 3#, 4#, 5# and 6# uplink-downlink configuration is 10ms, comprises a special subframe at first field, does not have special subframe in second field.

In special subframe, the ratio of UpPTS, DwPTS and GP also can adjust, and special subframe frame is configured with 9 kinds, is numbered 0 ~ 8, is designated as the configuration of 0# ~ 8# special subframe frame.As shown in following special subframe frame allocation list (table 2), UpPTS under the configuration of different special subframe frames, time shared by DwPTS and GP can be different, and table 2 only indicates the time of UpPTS and DwPTS, are exactly the time of GP with the time that 1ms deducts UpPTS and DwPTS.

Table 2

The up-downgoing switching cycle of what the present embodiment related to is LTE frame is the situation of 10ms.In order to the LTE base station and Wimax 16e base station that reduce neck frequency coexist are disturbed mutually, keep LTE system constant, modify to the frame of Wimax 16e system, amended frame is designated as W ' frame.The physical resource of W ' frame is configured to descender region, TTG, up region and RTG successively.The division in this region is consistent with Wimax 16e frame.Symbol duration, the resource type of W ' frame are also consistent with Wimax 16e frame with minimum duration of RTG etc.

In addition, also need to be configured according to the physical resource of frame configuration information to W ' frame of LTE system, comprising:

In time domain, the constraints in the descender region of LTE frame is comprised in, the shift time of the original position of the number LTE frame relative to the original position of Wimax 16e frame of downlink symbol in configuration Wimax 16e frame according to the descender region of Wimax 16e frame;

In time domain, the constraints in the up region of LTE frame is comprised in, the number of uplink symbol and the duration of TTG in configuration Wimax 16e frame according to the up region of Wimax 16e frame.

Above-mentioned configuration can be the configuration information of Wimax 16e base station according to the LTE frame of the LTE base station with its adjacent frequency coexistence, be configured the physical resource of the W ' frame of this base station, LTE frame configuration information comprises uplink-downlink configuration information, special subframe frame configuration information and cyclic prefix type information.

Above-mentionedly be configured to static configuration; Or, above-mentioned configuration non-static configuration, now, after LTE base station upgrades the configuration of LTE frame, the configuration information of the new LTE frame that will come into force be sent to described Wimax 16e base station (as, first can be sent to Wimax 16e core net by LTE core network, then be sent to described Wimax 16e base station by Wimax 16e core net), described Wimax 16e base station re-starts described configuration according to the configuration information of this new LTE frame.

W ' the frame obtained according to above-mentioned configuration as shown in Figure 5, further, two groups of continuous print downlink symbol are configured in the descender region of W ' frame, the original position of first group of downlink symbol and second group of downlink symbol is configured in the 5ms place after the original position of W ' frame and this original position respectively, the 1st downlink symbol in these two groups of downlink symbol is all configured with synchronizing channel, for sending synchronizing signal, and the control channel of Wimax 16e system configures from the downlink symbol of the 2nd in first group of downlink symbol, 2 downlink symbol can be taken, for transmitting system control signal, as indicated the signaling etc. of ascending resource position.Like this can compatible existing Wimax 16e terminal, make it access smoothly and to use.

In order to meet above-mentioned constraints, preferably, the original position of the original position of Wimax 16e frame with first descending sub frame after LTE frame special subframe to the duration of the original position (shift time get on the occasion of time correspondence offset manner backward) of this LTE frame or end position (shift time get on the occasion of time corresponding biased forwards mode), thus is alignd by the original position described shift time being configured to first descending sub frame in LTE frame after special subframe.

First group of downlink symbol configures in the descender region that duration is half frame length (5ms), and the time that Wimax 16e system uplink symbol and downlink symbol take is 102.857us.Therefore, when not considering the restriction of resource type to symbolic number, first group of configurable maximum symbolic number M of downlink symbol _d1.maxcan be calculated as follows:

Wherein, T _framefor the frame length of W ' frame, T _frame=10ms; T _symbolfor the duration of a symbol of W ' frame, T _symbol=102.857us.At some under other Wimax system configuration, T _symbolvalue can change, corresponding maximum symbolic number and TTG, RTG also will change, and following formula is the same, repeats no longer one by one.

Before can determining W ' frame by above formula, 5ms can put down at most 48 downlink symbol, and wherein first downlink symbol is for sending the first synchronizing signal.

According to the regulation of Wimax 16e agreement, when downlink resource is all PUSC, the downlink symbol number of Wimax 16e frame needs to be odd number, and when downlink resource is not PUSC entirely, as comprised FUSC and/or AMC, downlink symbol number does not just need the restriction by odd number number.On the other hand, when ascending resource is all PUSC, uplink symbol number must be the multiple of 3, when ascending resource is not PUSC entirely, as comprised AMC, uplink symbol number just do not need must be 3 multiple.

The present embodiment W ' frame is divided into two parts by front 5ms and rear 5ms, and these two parts are subject to the restriction of the relation of above-mentioned resource type and symbolic number respectively.

Can determine thus, when before W ' frame, the downlink resource of 5ms is all PUSC, the front 5ms of W ' frame arranges 47 downlink symbol, and when before W ' frame, the downlink resource of 5ms is not PUSC entirely, the front 5ms of W ' frame can arrange 48 downlink symbol.

For making the descender region of W ' frame be included in the descender region of LTE frame in time domain, the duration of the descender region of LTE frame should be less than or equal to after total duration of second group of downlink symbol adds 5ms, be called first condition.When W ' frame downlink resource is not PUSC entirely, the symbolic number of second group of downlink symbol of configuration is less than or equal to the maximum integer meeting this first condition, when W ' frame downlink resource is all PUSC, the symbolic number of second group of downlink symbol of configuration is less than or equal to the maximum odd number meeting this first condition.

When not considering the constraint of resource type to symbolic number, meet the maximum symbolic number M of second group of downlink symbol of first condition _d2.maxcan determine by following formula:

Wherein, T _frame, T _symbolimplication as described above; T _ds.LTEfor total duration of descending sub frames all in LTE frame; T _dwPTSfor the duration of DwPTS in LTE frame; represent and round downwards.T _ds.LTEand T _dwPTSthe uplink-downlink configuration of value and LTE, special subframe frame configure relevant with cyclic prefix type, can table look-up 1 and table 2 obtain.

When after W ' frame, the downlink resource of 5ms is all PUSC, the maximum symbolic number M of second group of downlink symbol _d2for being less than or equal to M _d2.maxmaximum odd number, when after W ' frame, the downlink resource of 5ms is not PUSC entirely, M _d2=M _d2.max.

Preferably, the requirement that the present embodiment aligns with the original position of UpPTS in LTE frame according to the original position in the up region by W ' frame, configures the duration of TTG in conjunction with the duration of second group of downlink symbol in the W ' frame of configuration.The computing formula of the duration of TTG can be derived according to the structure of Fig. 5 and LTE frame.

Such as, this TTG duration T _tTGcan be calculated as follows:

T _TTG＝T _off.UpPTS+T _off.Wimax-T _frame/2-M _D2·T _symbol

Wherein, T _off.UpPTSfor the original position of UpPTS in LTE frame is to the duration of the original position of this LTE frame; T _frame=10ms; T _off.Wimaxthe shift time of the original position of the relative LTE frame of the original position for W ' frame, by biased forwards mode get one on the occasion of; M _d2for the symbolic number of second group of downlink symbol in W ' frame; T _symbolfor the duration of a Wimax 16e system symbol.

If T _off.Wimaxby offset manner backward get one on the occasion of, then above-mentioned formula is variable turns to:
