Wherein, the embodiment of the present invention can be applied to (such as TD-LTE system) in TDD system, also can be applied to other needs dynamically to adjust in the system of subframe uplink-downlink configuration, for example TD-SCDMA system and follow-up evolution system thereof, WiMAX(Worldwide Interoperability for Microwave Access, micro-wave access global inter communication) system and follow-up evolution system thereof etc.

In declarative procedure below, first from the cooperation of network side and end side, implement to describe, finally from the enforcement of network side and end side, describe respectively, but this does not also mean that the two must coordinate enforcement, in fact, when network side and end side, separate while implementing, also solved respectively in network side, the existing problem of end side, when just the two is combined with, can obtain better technique effect.

Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.

As shown in Figure 2, the tdd communication systems of the embodiment of the present invention comprises: networking side apparatus 10 and terminal 20.

Networking side apparatus 10, for determining the subframe of radio frames, communicates according to the subframe in radio frames and terminal.

Terminal 20, for determining the subframe of radio frames, communicates according to the subframe in radio frames and networking side apparatus 10.

Wherein, the radio frames here comprises variable subframe, descending fixedly subframe and up fixedly subframe, descending fixedly subframe is that transmission direction is down direction and the changeless subframe of transmission direction, and the descending pilot frequency time slot in special subframe, up fixedly subframe is that transmission direction is up direction and the changeless subframe of transmission direction, variable subframe also further comprises up variable subframe and descending variable subframe, up variable subframe is the variable subframe being defined as uplink, and descending variable subframe is the variable subframe being defined as downlink transfer.

Uplink pilot time slot in embodiment of the present invention special subframe is identical with the function of uplink pilot time slot in special subframe in background technology, not in repeat specification.

Preferably, descending fixedly subframe comprises subframe 0 and the subframe 5 in each radio frames; Up fixedly subframe comprises subframe 2 and the subframe 7 in each radio frames; Special subframe comprises the subframe 1 in each radio frames.Other subframe is variable subframe.Further, subframe 6 can be special subframe, specifically can be referring to Fig. 7; Further, subframe 6 can also be descending fixedly subframe.

Wherein, after the subframe of network equipment 10 in determining radio frames, (descending reference symbol and/or down control channel represent three kinds of situations by descending sub frame, to send descending reference symbol and/or down control channel, the first only sends descending reference symbol, the second only sends down control channel, the third send descending reference symbol and send again down control channel, follow-up appearance and/or all comprise three kinds of meanings with the meaning is here similar, no longer describe in detail).The effect of descending reference symbol and/or down control channel is to allow terminal carry out blind Detecting, by blind check to descending reference symbol or the subframe of down control channel be descending sub frame.

The down control channel here includes but not limited to one or more in following signaling:

PCFICH, PDCCH and PHICH.

Accordingly, terminal 20 is carried out blind check to each subframe, using the subframe that descending reference symbol and/or down control channel detected as descending sub frame; If can't detect descending reference symbol and/or down control channel, think that this subframe is not descending sub frame.

Wherein, network equipment 10 can send up channel (by up fixedly subframe and/or up variable subframe carrying up channel by up fixedly subframe and/or up variable subframe by dispatch terminal, follow-up transmitting channel and the similar no longer repeat specification that looks like here) and/or upward signal, and send PDSCH data and/or down control channel by descending fixedly subframe and/or descending variable subframe.

Accordingly, terminal 20 receives PDSCH data and/or down control channel by descending fixedly subframe and/or descending variable subframe, and according to the scheduling of network side, by up fixedly subframe and/or up variable subframe, sends up channel and/or upward signal.

In force, network equipment 10 can only send ascending control channel by up fixedly subframe by dispatch terminal, and dispatch terminal only sends channel and/or the signal except ascending control channel in up channel and/or upward signal by up variable subframe.That is to say, by up variable subframe, send other up channels except ascending control channel, and/or send upward signal by up variable subframe.

Here the ascending control channel sending by up fixedly subframe includes but not limited to:

HARQ(Hybrid Automatic Repeat reQuest, mixed automatic retransfer request) feedback information, CSI(Channel State Information, channel condition information) feedback information and dispatch request and random access request.

Here by up variable subframe transmission up channel and/or upward signal, include but not limited to:

PUSCH data and SRS.

Accordingly, terminal 20, according to the scheduling of network side, only sends ascending control channel by up fixedly subframe, and only by up variable subframe, sends channel and/or the signal except ascending control channel in up channel and/or upward signal.

In force, network equipment 10 can increase subframe numbering in each uplink scheduling signaling, PUSCH data for subframe corresponding to scheduling sublayer frame number, and send descending scheduling signaling by descending fixedly subframe and/or descending variable subframe, for dispatching descending fixedly subframe and/or the descending variable subframe of this descending scheduling signaling of carrying.

Corresponding uplink scheduling (UL grant), network equipment 10 can be dispatched the PUSCH data in one or more subframes in a uplink scheduling signaling, and sends uplink scheduling signaling by descending fixedly subframe and/or descending variable subframe;

For descending scheduling (DL grant), the descending scheduling signaling that network equipment 10 sends is only for dispatching the descending sub frame of this descending scheduling signaling of carrying.

Accordingly, terminal 20 is according to the scheduled transmission data of network equipment 10.

Further, if terminal 20 blind checks to network side for dispatching the uplink scheduling signaling of subframe N, subframe N is not monitored, directly by subframe N, send data, wherein N is positive integer.

The subframe N here may be up fixedly subframe, may be also up variable subframe.

Wherein, up variable subframe and descending variable subframe that network equipment 10 is determined in variable subframe, and determine and send announcement information according to up variable subframe and the descending variable subframe determined, for notification terminal, according to announcement information, transmit data.

Accordingly, the announcement information that terminal 20 receives from network side, determines the subframe in radio frames and transmits data according to announcement information.

In force, network equipment 10 can send announcement information by down control channel or broadcast channel.

Such as network equipment 10 sends announcement information by down control channel, announcement information can be placed in to physical layer control channel, by descending fixedly subframe, send.

Suppose that subframe 0 and subframe 5 are descending fixedly subframes, network equipment 10 can be used a PDCCH carrying announcement information in the PDCCH public search space of subframe 0 and subframe 5; Can also be by MIB(Master Information Block, Master Information Block) in increase bit information the PBCH(Physical Broadcast Channel of mode in subframe 0, Physical Broadcast Channel) channel bearing.

It should be noted that, the embodiment of the present invention is not limited to the mode of above-mentioned transmission announcement information, and other can send the applicable equally embodiment of the present invention of mode of same intelligence information.

It is a variety of that network equipment 10 determines that the mode of announcement information has, and enumerates several below.

Mode one, network equipment 10 arrange sub-frame of uplink in certain hour length in bitmap(bit map) in the numerical value of corresponding bit, and the numerical value of descending sub frame corresponding bit in bitmap in setup times length, and using bitmap as announcement information.

Accordingly, terminal 20, according to the numerical value of each bit in bitmap, is determined sub-frame of uplink and descending sub frame in certain hour length.

In force, bitmap can only represent the transmission direction of variable subframe in certain hour length, has how many variable subframe bitmap just to have how many positions, then according to the transmission direction of variable subframe, determines the numerical value of corresponding bit position in bitmap.

Specifically duration can be stipulated in agreement, also can be by network side notification terminal 20; Can also upgrade the duration of setting as required.

Suppose that time span is the i.e. radio frames length of 10ms(), subframe 4,5,7 and 8 is variable subframes, bitmap is 4 altogether.If 1 represents sub-frame of uplink, 0 represents descending sub frame; If subframe 4,5 and 8 is up variable subframes, subframe 7 is descending variable subframes, and bitmap is exactly 1101.

Bitmap can also represent the transmission direction of all subframes in certain hour length, such as stipulating that special subframe represents descending sub frame, also can stipulate that special subframe represents sub-frame of uplink, invalid bit can also be arranged to in special subframe corresponding bit position.Because so the position terminal 20 of special subframe is just known in advance bit terminal that special subframe is corresponding and can not gone to resolve.The numerical value of the bit that concrete special subframe is corresponding can be set as required.

Bitmap also can only represent the transmission direction of all subframes except special subframe in certain hour length.

Concrete bitmap represents that subframe which subframe, each bit are corresponding and the implication of each bit numerical value can stipulate in agreement, can also be by network side notification terminal.

Mode two, network equipment 10 be according to the corresponding relation of configuration format and sequence number, determines sub-frame of uplink in certain hour length and the sequence number corresponding to configuration format of descending sub frame, and using definite sequence number as announcement information.Such as network equipment 10 carries out combined coding by all subframe directional combinations, determine corresponding sequence number.

Accordingly, terminal 20, according to the corresponding relation of configuration format and sequence number, is determined the configuration format that sequence number is corresponding, according to configuration format, determines sub-frame of uplink and the descending sub frame in certain hour length.

The corresponding relation of configuration format and sequence number can be stipulated in advance in agreement, also can be upgraded as required by network side, and notification terminal 20; Can also upgrade the corresponding relation of configuration format and sequence number as required.

Configuration format can only represent the up variable subframe in variable subframe and the configuration mode of descending variable subframe in certain hour length; The configuration mode that also can represent all sub-frame of uplink and all descending sub frames in certain hour length.

Suppose that certain hour length is the i.e. radio frames length of 10ms(), configuration format represents the configuration mode of all sub-frame of uplink and all descending sub frames in certain hour length, the corresponding relation of configuration format and sequence number can be referring to table 1.

Table 1

Wherein, D represents descending sub frame; S represents special subframe; U represents sub-frame of uplink.

Network equipment 10 checks that the configuration format of current 10ms is identical with which configuration format in table 1, and then determines corresponding sequence number, and sequence number is sent to terminal 20; Terminal 20 is checked configuration mode corresponding to sequence number of receiving according to table 1, thereby just knows which subframe is concrete each subframe be.

It should be noted that, table 1 just illustrates, the corresponding relation that does not represent configuration format and sequence number is certain identical with table 1, and the corresponding relation of configuration format and sequence number cannot be exhaustive, and other corresponding relations of configuration format and sequence number are applicable to the embodiment of the present invention too.

For mode one and mode two, network equipment 10 sends after announcement informations can also be by up channel and/or the upward signal of up fixedly subframe and/or up variable subframe receiving terminal 20, and by descending fixedly subframe and/or descending variable subframe transmission PDSCH data and/or down control channel; Accordingly, terminal 20 sends up channel and/or upward signal (such as transmitting user data, HARQ feedback information, CSI feedback information, dispatch request information, Random Access Channel (PRACH) by up fixedly subframe and/or up variable subframe, SRS etc.), and by descending fixedly subframe and/or descending variable subframe receive PDSCH data and/or down control channel.

Network equipment 10 can also only send down control channel by descending fixedly subframe, and only by up fixedly subframe, receives ascending control channel; Accordingly, terminal 20 only receives down control channel by descending fixedly subframe, and only by up fixedly subframe, sends ascending control channel (comprising HARQ feedback information, CSI feedback information, dispatch request, random access etc.).

If network equipment 10 sends by descending fixedly subframe, 20, terminal is carried out blind check in descending fixedly subframe; If network equipment 10 sends by descending variable subframe, 20, terminal is carried out blind check in descending variable subframe; If network equipment 10 sends by descending fixedly subframe and descending variable subframe, terminal 20 is carried out blind check in descending fixedly subframe and descending variable subframe.

Network equipment 10 can also be only by the HARQ feedback information of up fixedly subframe receiving terminal; Accordingly, terminal 20 is only by the HARQ feedback information of up fixedly subframe receiving terminal.

For mode one and mode two, network side, when dispatching, can increase subframe numbering, for PDSCH data or the PUSCH data of subframe corresponding to scheduling sublayer frame number (Subframe Index) in each PDCCH signaling.

Corresponding uplink scheduling, network equipment 10 can be dispatched the PUSCH data in one or more subframes in a PDCCH signaling, and sends uplink scheduling signaling by descending fixedly subframe and/or descending variable subframe;

For descending scheduling, network equipment 10 can be dispatched the PDSCH data in one or more subframes in a PDCCH signaling, and sends uplink scheduling signaling by descending fixedly subframe and/or descending variable subframe.

As shown in Figure 8, down control channel only sends ratio in descending fixedly subframe, and PDSCH data only send in descending variable subframe.Wherein in PDCCH, increase the indication of subframe numbering, for dispatch PDSCH or the PUSCH data in different subframes a DL subframe.Meanwhile, ascending control information PUCCH only sends in up fixedly subframe.

Mode three, network equipment 10 are arranged on the numerical value of subframe corresponding bit in bitmap that can carry ascending control channel in the sub-frame of uplink in certain hour length, and using bitmap as announcement information.

Accordingly, terminal 20, according to the numerical value of each bit in bitmap, is determined the subframe that can carry ascending control channel in the sub-frame of uplink in certain hour length.

In force, bitmap can only represent in variable subframe, can carry in certain hour length the subframe of ascending control channel, there are how many variable subframe bitmap just to have how many positions, then according to the subframe that can carry ascending control channel in variable subframe, determine bitmap.

Suppose that time span is the i.e. radio frames length of 10ms(), subframe 4,5,7 and 8 is variable subframes, bitmap is 4 altogether.If 1 representative can be carried ascending control channel, 0 representative can not be carried ascending control channel; If subframe 4,5 and 8 can not be carried ascending control channel, subframe 7 can be carried ascending control channel, and bitmap is exactly 0010.

Bitmap can also represent the subframe that can carry ascending control channel in all subframes in certain hour length.Because so the position terminal 20 of special subframe is just known in advance bit terminal that special subframe is corresponding and can not gone to resolve.

Bitmap also can only represent the subframe that can carry ascending control channel in all subframes except special subframe in certain hour length.

Mode four, network equipment 10, according to the corresponding relation of configuration format and sequence number, are determined the sequence number corresponding to configuration format of the subframe that can carry ascending control channel in the sub-frame of uplink in certain hour length, and using definite sequence number as announcement information.

Accordingly, terminal 20, according to the corresponding relation of configuration format and sequence number, is determined the configuration format that sequence number is corresponding, determines the subframe that can carry ascending control channel in the sub-frame of uplink in certain hour length according to configuration format.

Wherein, the subframe that can carry ascending control channel comprises up fixedly subframe and up variable subframe.

Configuration format can only represent in all subframes, can carry in certain hour length the subframe of ascending control channel; Also can only represent in all sub-frame of uplink, can carry in certain hour length the subframe of ascending control channel, this mode needs terminal 20 to know which subframe is sub-frame of uplink.

In the pattern of the configuration format in mode four and the corresponding relation of sequence number and mode two, the pattern of the corresponding relation of configuration format and sequence number is similar, does not repeat them here.

For mode three and mode four, network equipment 10 can also be by carrying the ascending control channel of the subframe receiving terminal 20 of ascending control channel in up fixedly subframe and/or variable subframe after sending announcement information, by the up channel/upward signal except ascending control channel of any sub-frame of uplink receiving terminal 20, and send PDSCH data and/or down control channel by descending fixedly subframe and/or descending variable subframe; Accordingly, the ascending control channel that terminal 20 sends by carrying the subframe of ascending control channel in up fixedly subframe and/or variable subframe, up channel/upward signal of sending out except ascending control channel by any sub-frame of uplink send, and receives PDSCH data and/or down control channel by descending fixedly subframe and/or descending variable subframe.

For mode three and mode four, network equipment 10 can increase subframe numbering in each uplink scheduling signaling, PUSCH data for subframe corresponding to scheduling sublayer frame number, and send descending scheduling signaling by descending fixedly subframe and/or descending variable subframe, for dispatching descending fixedly subframe and/or the descending variable subframe of this descending scheduling signaling of carrying.

Corresponding uplink scheduling, network equipment 10 can be dispatched the PUSCH data in one or more subframes in a uplink scheduling signaling, and sends uplink scheduling signaling by descending fixedly subframe and/or descending variable subframe;

For descending scheduling, the descending scheduling signaling that network equipment 10 sends is only for dispatching the descending sub frame of this descending scheduling signaling of carrying.

In force, the network equipment 10 of the embodiment of the present invention can carry out dynamic-configuration according to real-time business demand and/or channel conditions.Such as downlink business demand, can know according to information such as the current downlink business buffer area data volume in base station and types of service, uplink service demand can be known according to information such as the buffer status information (Buffer Status Report, BSR) of collection reporting of user and types of service.Such as current downlink business is many, can put some descending sub frames by polygamy; Current uplink service is many, can put some sub-frame of uplink by polygamy; Current downlink channel duty ratio is more serious, can put some descending sub frames by polygamy; Current up channel duty ratio is more serious, can put some sub-frame of uplink by polygamy.

Wherein, the network equipment of the embodiment of the present invention can be base station (such as macro base station, micro-base station, Home eNodeB etc.), can be also RN(relaying) equipment can also be other network equipment.

Based on same inventive concept, a kind of method of network equipment, terminal and time division duplex communication is also provided in the embodiment of the present invention, because the principle that these equipment are dealt with problems is similar to the system of time division duplex communication, therefore the enforcement of these equipment and method can, referring to the enforcement of system, repeat part and repeat no more.

As shown in Figure 3, the network equipment of the embodiment of the present invention comprises: the first subframe determination module 100 and first communication module 110.
