Embodiment
In existing LTE-TDD, regardless of whether using flexible sub-frame, the network equipment and the uplink-downlink configuration of all terminals All it is consistent, i.e., identical frame structure is used between the network equipment and each terminal.Usually, the network equipment is base station, It may also be the network side equipment of the other forms with similar functions, such as distributed antenna, distributed emission point etc..
In embodiments herein, the network equipment uses full duplex, and terminal uses half-duplex, consolidated network device service Different terminals can with different frame structures simultaneously and network device communications, the frame structure used for each terminal can be only Uplink-downlink configuration is on the spot carried out, i.e., there may be different uplink-downlink configurations in the frame structure that different terminals uses, due to upper Descending same frequency, therefore more may be referred to LTE-TDD pattern.In such a scenario, how to consult to change the frame of the terminal Structure is problem solved by the invention effectively to optimize system resource configuration.
In view of the needs of terminal initial access, the frame structure of an acquiescence is can specify that, the frame structure is set without network Held consultation between standby notice terminal or the network equipment and terminal.Under the frame structure of the acquiescence, the network equipment uses in advance about The time slot set and cycle send synchronizing signal, being initially accessed of receiving terminal to terminal, capability negotiation is carried out with terminal or Ability confirmation etc. is carried out with terminal, it is ensured that new terminal can be by this in the case where passing through negotiation not between the network equipment The frame structure of acquiescence accesses at any time, and the frame structure of acquiescence can be frame structure as defined in existing LTE-TDD or newly determine Justice, by taking table 1 as an example, the frame structure of acquiescence can be frame structure corresponding to any one index value in table 1, and the length of wherein frame can With (it is of course also possible to redefining new frame length as needed) identical with the length of frame in LTE-TDD, i.e., wrapped in each frame 10 subframes are included, the network equipment and terminal can preserve index value corresponding to the frame structure and frame structure defined such as table 1.When So, the frame structure of different acquiescences can also be set according to different frequency ranges, is repeated no more here.N kind frame knots are shared in table 1 Structure, maximum frame structure index value are n-1.It is the existing frame structures of existing LTE-TDD corresponding to index value 0~6, index value 7 It is the following n-7 kind frame structures that may be increased newly corresponding to~(n-1), frame structure x and x+1 represent appointing in this n-1 kind frame structure Two kinds of adjacent frame structures of meaning.It should be noted that n is not necessarily required to be more than 6, that is, it is not necessarily required to institute in existing LTE-TDD Some frame structures are all adopted in the lump, and especially, n can also be 1, i.e., only provide a kind of frame structure and by its frame knot by default Structure.Preferably, in order to which terminal is preferably synchronous, in the subframe that synchronizing signal is sent, be all configured to it is descending, such as can be in the 0th son Frame and the 5th sub-frame configuration send synchronizing signal.Without loss of generality, it is assumed that frame structure x be acquiescence frame structure and only in #0 (its Middle # represents that order, such as #0 represent No. 0, i.e., the 0th) subframe transmission synchronizing signal, then new terminal is only in the #2 of each frame Subframe sends access request, and the network equipment and terminal can carry out capability negotiation or requirement negotiation after access, be confirmed whether to adjust Whole frame structure.So through consultation, the network equipment can think the independent scheduling frame structure of each terminal so that each whole End can find respective suitable frame structure, can be obviously improved systematic function.Negotiations process once terminates, the network equipment and end The frame structure that end just determines according to negotiation result is communicated.
For embodiments herein in network equipment full duplex, the semiduplex pattern of terminal, the network equipment can be according to end The demand at end, neatly adjust the frame structure of terminal.The network equipment can be network side equipment, for example, base station or Terminal, for example, in D2D communications, by the role that the network equipment is undertaken as the terminal of emitter.For ease of understand, below It is described by taking the network equipment as an example.
The full duplex frame structure ascending-descending subframes of table 1 configure
A kind of method that full duplex frame structure is adjusted flexibly includes：After connection is established according to the frame structure of acquiescence, or During communication is carried out, the network equipment and terminal consult to change the frame structure of terminal.For example current frame structure is in table 1 Frame structure j (0≤j≤n-1, this frame structure can be the frame structure or adjusted frame knot before of acquiescence Structure), the frame structure that the network equipment and terminal consult change terminal is frame structure i shown in table 1 (0≤i≤n-1, i ≠ j), it is this more Changing can be triggered by the network equipment, can also be triggered by terminal.
Illustrated below by different embodiments, it should be pointed out that either which embodiment, for All it is any terminal of network device services, different terminals can independently be modified frame structure, need not impose each other consistent. Due to being the adjustment that frame structure is individually carried out to each terminal, therefore no matter agree to or disagree change, unless otherwise instructed, Response message hereinafter using the information of new frame structure is all that a terminal is individually sent for instruction terminal.It is special Not, if one group of terminal (and not all terminal) that the network equipment is serviced it is uniformly modified, then response message or Person is used for instruction terminal using the information that instruction terminal group can be included in the information of new frame structure or by whole in the group Transmission represents that this is the change to the unified frame structure carried out of this group of terminal on common source corresponding to end, changes frame structure Method and principle are consistent with the method and principle of terminal change frame structure.Without loss of generality, the application is with a terminal Exemplified by.
Embodiment one
When the network equipment and terminal consult the frame structure of change terminal, frame structure change request can be initiated by terminal.For example, Pair shown in Figure 3, (attention is any terminal here, i.e., for any terminal that terminal 100 in Fig. 3 services for the network equipment 200 The different terminals of network device services can do each independent processing), in step 301, terminal 100 is in currently used frame knot When structure is unsatisfactory for needing, frame structure change request is sent to the network equipment 200, the frame structure change request is used to ask network Equipment 200 changes the currently used frame structure of the terminal, naturally it is also possible to is named as other signaling titles；In step 302, The network equipment 200 determines whether to agree to that change terminal 100 is currently used after receiving the frame structure change request of the transmission of terminal 100 Frame structure, response message is sent to terminal 100 in step 303, if the network equipment 200 is agreed to change, in the response message Including for indicating information of the terminal 100 using new frame structure, if the network equipment 200 disagrees change, the sound Information is answered to include being used to indicate that the network equipment 200 disagrees the letter for changing the currently used frame structure of the terminal 100 Breath.Then in the network equipment 200 of step 304 and terminal 100 just according to response message in the frame structure that confirms communicated.
The situation for the needs that the current frame structure of terminal is unsatisfactory for terminal has a lot, for example, the acquiescence that terminal is currently used Frame structure is not suitable for the business of terminal, or the terminal business of the terminal, terminal during with network device communications One or more parameter in the channel quality of position, the interference that the terminal is subject to and the terminal changes etc..Lift individual For specific example, if the currently used acquiescence frame structure of terminal is frame structure x+1, most of son under x+1 frame structures Frame be all allocated to it is descending, if but current business is the uploaded videos or the Large Copacity industry such as upload software bag initiated by terminal Business, then have clearly a need for more ascending resources to transmit larger data flow, and the requirement to downlink resource be not it is too high, at this moment It is not just very suitable to wait frame structure x+1, it is therefore desirable to the frame structure of more sub-frame of uplink, such as frame structure 0 is configured, such a In the case of, terminal can sends a frame structure change request to the network equipment, asks the network equipment by the frame structure of terminal It is changed to the desired new frame structure 0 of terminal or the frame structure of other suitable terminal current business.As another example, such as Fig. 4 institutes Show, if frame structure currently used terminal A is frame structure x+1, after the terminal location A is moved, with being led to using frame structure 2 Another terminal B location of letter is very close to the adjacent terminal end in i.e. Fig. 4, so its special subframe are by terminal B uplink communications Severe jamming, i.e. terminal A position and interference are all changed, correspondingly, terminal B the 3rd, 8 descending sub frame also by The severe jamming of terminal A uplink communication, the heavily disturbed subframes of terminal A and terminal B are marked with italic in figure, at this moment Wait, terminal A and terminal B cans send a frame structure change request to the network equipment, and frame structure is changed to by Terminal A requests Frame structure 2 simply requests change frame structure, and terminal B is also asked frame structure being changed to frame structure x+1 or simply requested more Change frame structure, the network equipment can select uniformly for frame structure to be adjusted to frame knot after terminal A and terminal B request is received respectively Structure 2, can also select to agree to frame structure to be adjusted to frame structure x+1, it is also an option that for terminal A and terminal B select one it is new Identical frame structure, terminal A and terminal B is notified respectively, such terminal A and terminal B are with the frame structure and the network equipment of notice Communication, frame structure can is synchronous, reduces the interference because being brought the change of position and interference.In addition, terminal may be used also With the change according to type of service, the interference of other-end suffered by terminal itself, the either change of channel quality or position Change, or other situations, frame structure change request is actively initiated to the network equipment.
Terminal is refer in above-mentioned example can also include the end in the frame structure change request sent to the network equipment The information of desired new frame structure is held, i.e. terminal can actively tell the network equipment oneself it is expected which kind of frame structure used.Example Such as, terminal can find suitable frame structure (i.e. the desired new frame structure of terminal) in the frame structure concordance list of similar table 1, So-called suitable frame structure, it is the selection that the disturbed condition that is subject to according to itself of terminal, the factor such as type of service are made, and should The information (for example, index value of the frame structure) of frame structure is placed in frame structure change request and is sent to the network equipment in the lump, such as Similar with the flow shown in Fig. 3 shown in Fig. 5, the terminal 100 in Fig. 5 (pays attention to this for any terminal that the network equipment 200 services In be any terminal, i.e., the different terminals of network device services can be done with each independent processing), in step 401 terminal 100 Being sent to the network equipment 200 includes the frame structure change request of desired frame structure, and the network equipment is confirmed whether together in step 402 Anticipate the request, and response message is sent to terminal 100 in step 403, the response message can be that a request is confirmed (referring to figure Shown in 5, the response message or request confirm be 1 bit, it is necessary to which explanation, the request confirm to can also be by multiple What bit carried, for example, it is contemplated that the factor such as coding need to carry in the case of more information may more than 1 bit), Then the corresponding frame structure of terminal 100 and the network equipment 200 are just confirmed in step 404 by request content communicates, i.e., if Agree to, then communicated by the desired frame structure of terminal, if disagreeing, then or led to by the current frame structure of terminal Letter.Terminal can not also tell the network equipment it is expected which kind of frame structure used, by the network equipment according to the type of service of terminal come Suitable frame structure is determined for terminal, for example, terminal when initiating business request, has notified the industry needed for the network equipment Service type, therefore, terminal can also the change request of transmission frame structure it is expected to use which kind of frame structure, network without carried terminal Equipment receive terminal transmission frame structure change request after, can the load based on the network equipment, the type of service needed for terminal, Terminal positional information that the network equipment is obtained, channel quality, one or more of the parameter such as interference of terminal are come for terminal It is determined that suitable new frame structure, it should be noted that need to only assess the interference itself being subject to different from terminal, the network equipment exists When assessing disturbed condition, not only to consider the interference that the terminal is subject to, also to assess the interference of the terminal-pair other-end, therefore Here it is referred to as (similarly hereinafter) with ' interference of terminal '.After the network equipment receives the frame structure change request of terminal transmission, in spite of Agree to change, can all give one response message of terminal replies, if the network equipment agrees to change, the response message includes using The information of new frame structure is used in the instruction terminal.If the network equipment disagrees change, or the new frame redefined Structure or current frame structure, then response message, which includes disagreeing for instruction, changes the currently used frame knot of the terminal The information of structure.
If agreeing to change, then following several feelings be present after the frame structure change request of terminal transmission is received in the network equipment Condition：
(1) if not having to include the desired new frame structure of terminal in frame structure change request, the network equipment is eventually End determines a kind of new frame structure, and this new frame structure is more suitable for the current type of service or scene of terminal；
(2) if containing the desired new frame structure of terminal in frame structure change request, and the network equipment is agreed to, Then the network equipment is determined using the desired new frame structure of terminal as new frame structure；
(3) if containing the desired new frame structure of terminal in frame structure change request, but the network equipment is different Meaning, then the network equipment is that terminal determines a kind of new frame structure；This new frame structure is more suitable for the current type of service of terminal Or scene.
How the network equipment already discussed above, which is terminal, determines new frame structure, and therefore, here is omitted.
The network equipment is after terminal determines new frame structure, sends response message to terminal.Terminal receives response letter Communicated after breath using between new frame structure and the network equipment.
If the information of included desired new frame structure, network are set in the frame structure change request that terminal is sent Preparation give can simply be carried in the response message of terminal agree or disagree terminal use it is described desired new The information of frame structure, such as, using ACK/NACK (Chinese full name in existing communication agreement：Confirm/do not confirm；It is English complete Claim：Acknowledged/Not Acknowledged) signal sending method, ack signal agrees the frame knot of terminal suggestion Structure, NACK represent to disagree the desired new frame structure of terminal.Or using whether using the desired new frame structure of terminal as One domain is put into existing down control channel, so, it is only necessary to a bit, for example agreed with 1, with 0 table Show and disagree.Especially, there is a more simplified response mode, i.e., the network equipment not only represents to disagree terminal desired with 0 Frame structure, and be also represented by disagreeing terminal change frame structure, otherwise that is, using the desired new frame structure of terminal, or just after Continuous current frame structure, Fig. 5 just give this response mode, and this response mode is easier, has certainly in flexibility It is short of, belongs to one and take into account complexity and the half-way house of flexibility.
If the change request that terminal is sent does not include desired new frame structure, or the network equipment finally determine it is new Frame structure be different from the desired new frame structure of terminal, then the network equipment then includes new uplink/downlink frames in response message The index of structure or new uplink/downlink frames structure.Response message can be sent to terminal by an independent message, also may be used Terminal is sent to be included in other message, such as is directly included in PDCCH (Chinese full name：Descending control physical channel；English Literary full name：Physical Downlink Control Channel) etc. up-downgoing schedules control channels or RRC (Chinese full name： Radio resource control layer；English full name：Radio Resource Control) in signaling.
The network equipment, if disagreeing change, can also refuse the frame after the frame structure change request of terminal transmission is received Structure change request.For example, the network equipment is believed according to current loading condition, the business of terminal, position, disturbed condition or channel One or more judgement in the parameters such as breath can not change frame structure, then can refuse frame structure change request, this In the case of, terminal is also according to original frame structure and network device communications.Or the network equipment confirm new frame structure with It is same to represent that the network equipment disagrees the change request when the original frame structure of terminal is consistent.Especially, even if such case Under, the index of the currently used frame structure of terminal still can be sent to terminal by the network equipment by response message, and terminal is received To after the message, find as the index value of the index value frame structure currently used with terminal of frame structure in response message, Thereby determine that the network equipment refuses the request of this change frame structure of the terminal.
For above-mentioned terminal only send frame structure change request without specify desired new frame structure mode, this be by There are more global informations in the network equipment, be advantageous to make the scheduling for being more suitable for system, while the place of terminal can also be simplified Reason, be advantageous to extend the life-span of terminal.
And for specifying the mode of desired new frame structure by terminal, it can increase terminal processes complexity, but can be with Terminal is obtained most suitable frame structure, lift Consumer's Experience.
Further, if terminal finds that new frame structure is not met by demand, frame structure can be initiated again more Change request.
Generally, the network equipment is changed to new frame structure in the next frame for sending and receiving response message with terminal.Especially Ground, the network equipment can also determine the time of frame structure change starting, and include the frame in the response message for being sent to terminal The time of structure change starting, in this case, the network equipment can change the time originated by frame knot with terminal in the frame structure Structure is changed to new frame structure and communicated.
Embodiment two
Illustrated in above embodiment so that terminal initiates frame structure change request as an example, in practical application In, frame structure change request can also be initiated by the network equipment.
The network equipment current frame structure be unsatisfactory for terminal or the network equipment determined when needing for the terminal it is new Frame structure；The network equipment is sent for indicating that the terminal uses the information of new frame structure to the terminal.Terminal The situation that current frame structure is unsatisfactory for the needs of terminal has the description that much specifically may refer to preceding embodiment one.Terminal The load for needing to be primarily referred to as the network equipment that current frame structure is unsatisfactory for the network equipment can not support that terminal is current well Frame structure, such as the network equipment at full capacity in the case of, there is new business to add again, at this time, the network equipment is not The frame structure of all original terminals can be maintained well, it is necessary to some in all original terminals of active accommodation or a certain portion Divide the frame structure of terminal, reach new load balance.Determine that new frame structure can also join as how the network equipment is terminal See the description of preceding embodiment one.
For example present terminal A frame structure is frame structure 0, most of subframe is all allocated to up under the frame structure, But if the network equipment is the transmission Large Copacity business such as video for the business of the other-end near terminal A, at this time in order to control Interference of the terminal A processed uplink for other-end, the network equipment can suitably be subtracted with active accommodation terminal A frame structure Its few uplink, such as it is changed to frame structure 2.
Pair as shown in fig. 6, (attention is any terminal here to any terminal that terminal 100, which is the network equipment 200, to be serviced, i.e., The different terminals of the network device services can do each independent processing), the network equipment 200 can be current according to terminal 100 Type of service (for example, change of type of service), the positional information of terminal 100, the channel quality of terminal 100, terminal 100 One or more of interference, the load of the network equipment 200 or other situations determine that the current frame structure of the terminal 100 needs Adjustment, then the network equipment 200 actively initiates to change frame structure, for example, directly being sent in step 501 to terminal 100 for referring to Show information of the terminal 100 using new frame structure (for example, index value corresponding to new frame structure).In addition, this is used to indicate Terminal 100 can be sent to terminal 100 using the information of new frame structure by an independent message, can also be included in it Terminal 100 is sent in its message, such as is directly included in the up-downgoing such as PDCCH schedules control channels or RRC signaling.It is different The network equipment is needed to agree in the uplink/downlink frames structure change request initiated by terminal, this change initiated by the network equipment is straight Terminal is known in connection.Certainly, terminal can also determine to agree to or refuse the response message of change, but consider the network equipment Have more global informations and scheduling of resource carried out by the network equipment, so general it is not recommended that the step, this be also in Fig. 6 Step 502, the reason for being represented by dotted lines ' to the response for instruction terminal using the information of new frame structure ' of terminal 100, Represent that terminal does not use the step typically, but directly receive the uplink/downlink frames structure of network equipment change, then in step 503 terminals 100 just communicate with the network equipment 200 according to the new frame structure changed.
The usual network equipment is being sent and received for indicating that the terminal uses the information of new frame structure with terminal Next frame is changed to new frame structure.Especially, what the network equipment was sent is used to indicate that the terminal to use new frame structure The time of frame structure change starting can also be included in information, the network equipment can be changed with terminal in the frame structure in this case Frame structure is changed to new frame structure and communicated by the time of starting.
