Wherein, the embodiment of the invention can be applied to (such as the TD-LTE system) in the 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 the declarative procedure below, implement to describe from the cooperation of network side and end side earlier, describe from the enforcement of network side and end side respectively at last, but this does not also mean that the two must cooperate enforcement, in fact, separate when implementing, also solved respectively in network side, the existing problem of end side when network side and end side, when just the two is used in combination, can obtain better technique effect.

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

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

Networking side apparatus 10 is used for determining communicating the subframe of radio frames according to subframe in the radio frames and terminal.

Terminal 20 is used for determining communicating the subframe of radio frames according to subframe in the 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 the 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 that is defined as uplink, and descending variable subframe is the variable subframe that is defined as downlink transfer.

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

Preferable, 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 a 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 are represented three kinds of situations to send descending reference symbol and/or down control channel by descending sub frame, first kind only sends the descending reference symbol, second kind only sends down control channel, the third promptly sends the descending reference symbol and sends down control channel again, follow-up appearance and/or all comprise three kinds of meanings with the meaning here is 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, with blind check to the 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 the following signaling:

PCFICH, PDCCH and PHICH.

Accordingly, terminal 20 is carried out blind check to each subframe, will detect the subframe of descending reference symbol and/or down control channel as descending sub frame; If detect less than descending reference symbol and/or down control channel, think that then this subframe is not a descending sub frame.

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

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, sends up channel and/or upward signal by up fixedly subframe and/or up variable subframe.

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 that ascending control channel in up channel and/or the upward signal by up variable subframe.That is to say, by up variable subframe transmission other up channels except that ascending control channel, and/or by up variable subframe transmission upward signal.

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

HARQ (Hybrid Automatic Repeat reQuest mixes automatic repeat requests) feedback information, CSI (Channel State Information, channel condition information) feedback information and dispatch request and access request at random.

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

PUSCH data and SRS.

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

In force, network equipment 10 can increase the subframe numbering in each bar uplink scheduling signaling, the PUSCH data that are used for the subframe of scheduling sublayer frame number correspondence, and, be used to dispatch the descending fixedly subframe and/or the descending variable subframe of this descending scheduling signaling of carrying by descending fixedly subframe and/or descending variable subframe transmission descending scheduling signaling.

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 the 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 only is used to dispatch 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 are not then monitored subframe N to the uplink scheduling signaling that is used to dispatch subframe N of network side, directly send data by subframe N, wherein N is a positive integer.

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

Wherein, network equipment 10 is determined up variable subframe and the descending variable subframe in the variable subframes, and determines and send announcement information according to the up variable subframe of determining and descending variable subframe, is used to notify terminal to transmit data according to announcement information.

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

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

Send announcement information such as network equipment 10 by down control channel, then announcement information can be placed physical layer control channel, send by descending fixedly subframe.

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

Need to prove that the embodiment of the invention is not limited to the mode of above-mentioned transmission announcement information, other modes that can send with intelligence information are suitable for the embodiment of the invention equally.

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 are provided with the numerical value of sub-frame of uplink corresponding bit in bitmap (bit map) in the certain hour length, and the numerical value that the corresponding bit in bitmap of descending sub frame in the time span is set, and with bitmap as announcement information.

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

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

Concrete duration can be stipulated in agreement, also can notify terminal 20 by network side; Can also the duration of setting be upgraded as required.

Suppose that time span is 10ms (i.e. radio frames length), subframe 4,5,7 and 8 is variable subframes, and then 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 then bitmap is exactly 1101.

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

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

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

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

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

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

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

Suppose that certain hour length is 10ms (i.e. radio frames length), configuration format is represented the configuration mode of all sub-frame of uplink and all descending sub frames in the certain hour length, and then 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 the table 1, and then definite corresponding sequence number, and sequence number is sent to terminal 20; Terminal 20 is checked the configuration mode of the sequence number correspondence of receiving according to table 1, thereby just knows which subframe is concrete each subframe all be.

Need to prove, table 1 just illustrates, do not represent the corresponding relation of configuration format and sequence number certain identical with table 1, the corresponding relation of configuration format and sequence number can't be exhaustive, and other corresponding relations of configuration format and sequence number are applicable to the embodiment of the invention too.

At mode one and mode two, network equipment 10 sends after the announcement informations can also be by the 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 receives ascending control channel by up fixedly subframe; Accordingly, terminal 20 only receives down control channel by descending fixedly subframe, and only sends ascending control channel (comprising HARQ feedback information, CSI feedback information, dispatch request, access etc. at random) by up fixedly subframe.

If network equipment 10 sends by descending fixedly subframe, then 20 at terminal is carried out blind check in descending fixedly subframe; If network equipment 10 sends by descending variable subframe, then 20 at terminal is carried out blind check in descending variable subframe; If network equipment 10 sends by descending fixedly subframe and descending variable subframe, then 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, the terminal 20 HARQ feedback information by up fixedly subframe receiving terminal only.

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

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

Such as shown in Figure 8, down control channel only sends in descending fixedly subframe, and the PDSCH data only send in descending variable subframe.Wherein increase the indication of subframe numbering among the PDCCH, be used for PDSCH or PUSCH data in the different subframes of DL subframe scheduling.Simultaneously, ascending control information PUCCH only sends in up fixedly subframe.

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

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

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

Suppose that time span is 10ms (i.e. radio frames length), subframe 4,5,7 and 8 is variable subframes, and then 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 then bitmap is exactly 0010.

Bitmap can also represent the subframe that can carry ascending control channel in all subframes in the certain hour length.So can not go to resolve because the position terminal 20 of special subframe is just known the bit terminal of special subframe correspondence in advance.

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

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

Accordingly, terminal 20 is determined the configuration format of sequence number correspondence according to the corresponding relation of configuration format and sequence number, determines the subframe that can carry ascending control channel in the sub-frame of uplink in the 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 can carry in all subframes in the certain hour length subframe of ascending control channel; Also can only represent can carry in all sub-frame of uplink in the certain hour length subframe of ascending control channel, this mode needs terminal 20 to know which subframe is a sub-frame of uplink.

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

At 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 after sending announcement information in up fixedly subframe and/or the variable subframe, by the up channel/upward signal except that ascending control channel of any sub-frame of uplink receiving terminal 20, and by descending fixedly subframe and/or descending variable subframe transmission PDSCH data and/or down control channel; Accordingly, the ascending control channel that terminal 20 sends by the subframe that can carry ascending control channel in up fixedly subframe and/or the variable subframe, up channel/upward signal of sending out except that 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.

At mode three and mode four, network equipment 10 can increase the subframe numbering in each bar uplink scheduling signaling, the PUSCH data that are used for the subframe of scheduling sublayer frame number correspondence, and, be used to dispatch the descending fixedly subframe and/or the descending variable subframe of this descending scheduling signaling of carrying by descending fixedly subframe and/or descending variable subframe transmission descending scheduling signaling.

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

For descending scheduling, the descending scheduling signaling that network equipment 10 sends only is used to dispatch the descending sub frame of this descending scheduling signaling of carrying.

In force, the network equipment 10 of the embodiment of the invention can carry out dynamic-configuration according to real-time business demand and/or channel conditions.For example the downlink business demand can be known according to information such as current downlink business buffer area data volume in base station and types of service, the uplink service demand can according to the buffer status information of collecting reporting of user (Buffer Status Report, BSR) and information such as type of service know.Many such as current downlink business, can put some descending sub frames by polygamy; Current uplink service is many, can put some sub-frame of uplink by polygamy; The 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 invention can be base station (such as a macro base station, little base station, Home eNodeB etc.), also can be RN (relaying) equipment, can also be other network equipment.

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