Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, belongs to the scope of protection of the invention.
First embodiment
Shown in Figure 3, first embodiment of the invention provides a kind of dispatching method, applied to base station, includes the following steps
301~step 303, details are as follows.
Step 301：Define the time slot adjustment cycle.
In the embodiment of the present invention, time slot that base station the defines adjustment cycle may include at least three time slots, and this at least three
Time slot is divided into fixed descending time slot, fixed ascending time slot and Flexible timeslot.
Wherein, the situation based on a variety of subcarrier spacing configurations at present, the time slot adjustment cycle can be there are two types of set-up mode：
Mode one：The time slot adjustment cycle has fixed number of time slot
For example, subcarrier spacing is 60KHz, the length that 10 time slots adjust cycle, then 1 time slot for 1 time slot is defined
For 0.125ms, 10 time slots corresponding cycle is 1.25ms.
Mode two：The time slot adjustment cycle has regular time length
For example, the fixed time slot adjustment cycle is 5ms, then it is 60KHz in subcarrier spacing, 1 time slot adjusts
Cycle includes 40 time slots.
In the embodiment of the present invention, the time slot in the time slot adjustment cycle can be divided into fixed descending time slot, fixed ascending time slot
And Flexible timeslot.
In general, the first time slot in the time slot adjustment cycle is fixed descending time slot (default configuration).During the fixation downlink
Gap includes at least down control channel, for carrying the scheduling and control in time slot adjustment cycle.The fixation descending time slot may be used also
To include downlink data transmission channel, downlink data signal is sent for base station.And the fixation downlink in the time slot adjustment cycle
The number of time slot can be based on the network planning and Optimization Experience is configured, and can be 2 or 3 etc., the present invention does not limit it
System.
The last one time slot in the time slot adjustment cycle is fixed ascending time slot (default configuration).The fixation ascending time slot
Including at least uplink control channel.In a tdd system, which can also include transmitting uplink data channel, use
In the transmission of upstream data signals；In FDD system, which can be in another band transmissions, institute
It is optional so that whether the fixation ascending time slot transmits upstream data signals.The time slot adjusts the fixation ascending time slot in the cycle
Number can be based on the network planning and Optimization Experience is configured, and can be 2 or 3 etc., the present invention is not limited.
The Flexible timeslot is a kind of new time slot type introduced, when can be dynamically set, such as can be arranged to uplink
Gap UL receives data corresponding to base station and terminal sends data, can also be arranged to descending time slot DL, number is sent corresponding to base station
Data are received according to terminal, can also be arranged to free timeslot empted, base station and terminal do not work.The Flexible timeslot is usual
Remaining time slot in addition to fixed descending time slot and fixed ascending time slot in the cycle is adjusted for the time slot.
In order to preferably adjust time slot ratio, it is preferred that when defining the time slot adjustment cycle, can the time slot only be adjusted week
First interim time slot is divided into fixed descending time slot, the last one time slot is divided into fixed ascending time slot, remaining time slot is
Time slot in addition to first time slot and the last one time slot is divided into Flexible timeslot, i.e. the acquiescence with the time slot adjustment cycle is matched somebody with somebody
It is identical to put mode.
In the embodiment of the present invention, due to easily there is a situation where that neighbor cell time slot ratio is inconsistent on Flexible timeslot, so as to
Inter base station interference or terminal room interference are introduced, so, it, can be on the Flexible timeslot in order to avoid between base station and the interference of terminal room
It introduces and perceives the cycle (Sensing Period, abbreviation SP), send perceptual signal for transmitter, receiver is believed based on the perception
It number measures and perceives interference information.Here transmitter can be base station or terminal, and receiver is also identical.
Specifically, the Flexible timeslot includes SP, which sends and receives for perceptual signal.The SP can be additionally used in data
Signal sends and receives.Typical SP can be 1 orthogonal frequency division multiplexi (Orthogonal Frequency
Division Multiplexing, abbreviation OFDM) symbol time.SP can be located at any one character position of Flexible timeslot,
But it in order to obtain interference information before data receiver, realizes being properly received for better follow-up data, preferably, which can be matched somebody with somebody
First character position of Flexible timeslot is put, as shown in Figure 4.
When the previous time slot of an ascending time slot of certain cell is descending time slot, the descending time slot to the ascending time slot
Transfer point usually require a guard time (Guard Period, abbreviation GP), and the position where the SP can be used for GP, such as
Shown in Fig. 4.
Step 302：The time slot is adjusted into each Flexible timeslot in the cycle and is arranged to descending time slot, ascending time slot or free time
Time slot.
In the embodiment of the present invention, base station, can be periodically according to the uplink of this cell when being configured to Flexible timeslot
It is configured with the time slot configuration information of downlink traffic and/or adjacent cell, specific method is as follows：
First, according to predetermined period, the time slot of the uplink and downlink portfolio and/or adjacent cell that obtain this cell is matched somebody with somebody for base station
Confidence ceases；Then, base station is believed according to the uplink and downlink portfolio of this cell got and/or the time slot configuration of adjacent cell
The time slot is adjusted each Flexible timeslot in the cycle and is arranged to descending time slot, ascending time slot or free timeslot by breath.
It is pointed out that the information that base station is got can be the uplink and downlink portfolio of this cell, or
The time slot configuration information of adjacent cell, or the uplink and downlink portfolio of this cell and the time slot configuration information of adjacent cell.
The predetermined period is usually the integral multiple of time span possessed by the time slot adjustment cycle, such as 1 times, 2 times, 5 times
Deng of the invention not to be limited.The predetermined period can be sent to this cell terminal by base station by system broadcast information.
The descending time slot can correspond to a variety of (downlink) time slot types, such as the descending time slot with down control channel, non-band
The descending time slot of down control channel, self-contained descending time slot, pure descending time slot etc..The ascending time slot can correspond to a variety of (uplinks)
Time slot type, for example, the ascending time slot with uplink control channel, not the ascending time slot with uplink control channel, self-contained uplink when
Gap, pure ascending time slot etc..And Flexible timeslot is specifically arranged to which kind of descending time slot or ascending time slot, base station can be according to business
The decisions such as demand.
In the embodiment of the present invention, base station is configured Flexible timeslot according to the uplink and downlink portfolio of this cell
Mode, specially：
According to the uplink and downlink portfolio of this cell, when estimating the required ascending time slot number of this cell and downlink
Gap number；
Cycle, ascending time slot number and descending time slot number are adjusted according to the time slot, which adjusted each in the cycle
Flexible timeslot is arranged to descending time slot, ascending time slot or free timeslot.
Wherein, the method example of ascending time slot number and descending time slot number is estimated according to uplink and downlink portfolio in base station
Such as it is：
Ascending time slot number=upstream traffic ÷ (uplink spectrum efficiency × ascending time slot efficient resource number)；
Descending time slot number=downlink traffic ÷ (downstream spectrum efficiency × descending time slot efficient resource number).
Further, after ascending time slot number and descending time slot number is estimated, the side that is configured to Flexible timeslot
Method is, for example,：
It is assumed that：The number of time slot included by one time slot adjustment cycle is N, when time slot adjusts the fixation downlink in the cycle
The number of gap is N1, and the number of fixed ascending time slot is N2, and the ascending time slot number estimated is Nu1, and descending time slot number is
Nd1；
If Nu1≤N2 and Nd1≤N1, time slot is adjusted into each Flexible timeslot in the cycle and is arranged to free timeslot；Or
If Nu1 ＞ N2 and Nd1≤N1, min (N-N1-N2, Nu1-N2) a time slot in Flexible timeslot is arranged to
Ascending time slot；Or
If Nu1≤N2 and Nd1 ＞ N1, min (N-N1-N2, Nd1-N1) a time slot in Flexible timeslot is arranged to
Descending time slot；Or
If Nu1 ＞ N2 and Nd1 ＞ N1, and (Nu1+Nd1)≤N, then (Nd1-N1) a time slot in Flexible timeslot is set
For descending time slot, (Nu1-N2) a time slot is arranged to ascending time slot；Or
If Nu1 ＞ N2 and Nd1 ＞ N1, and (Nu1+Nd1) ＞ N, then by ([N × Ndl/ (Ndl+ in Flexible timeslot
Nul)]-N1) a time slot is arranged to descending time slot, and ([N × Nul/ (Ndl+Nul)]-N2) a time slot is arranged to ascending time slot.
Wherein, min represents to take smaller one between two numerical value, and [] represents round.
It should be noted that since fixed descending time slot is usually located at the front end in time slot adjustment cycle, i.e., Flexible timeslot it
Before, so, it, can mode be selected successively in order from all Flexible timeslots when selecting Flexible timeslot being arranged to descending time slot
It selects, and since fixed ascending time slot is usually located at the rear end in time slot adjustment cycle, i.e., after Flexible timeslot, so, it selects spirit
When time slot living is arranged to ascending time slot, sequential mode can be pushed down from all Flexible timeslots and made choice successively, to meet business need
It asks.
For example, if N, which is equal to 10, N1 and N2, is equal to 2, then selection, can be from the 3rd when Flexible timeslot is arranged to descending time slot
The order of a time slot to the 8th time slot makes choice；It, can be from the 8th time slot when Flexible timeslot is arranged to ascending time slot by selection
Order to the 3rd time slot makes choice.
Base station is configured Flexible timeslot according to the time slot configuration information of adjacent cell, mainly the time slot tune to this cell
It optimizes complete cycle and adjusts, mode is, for example,：If base station detects and this cell close coupling (interfering with each other property is very strong)
Adjacent cell time slot configuration and this cell time slot configuration it is inconsistent, then, will be low excellent according to native region priority and load
The time slot configuration of first grade either this cell of low-load is adjusted to the time slot configuration of the adjacent cell with high priority or high load
Unanimously.
Step 303：Type dispatch terminal based on the time slot in the time slot adjustment cycle after setting.
In the embodiment of the present invention, for dispatch terminal, scheduling information can be transmitted to terminal in base station.
Wherein, which cannot be only used for instruction base station (i.e. this cell base station) in the reception of corresponding ascending time slot
Row data-signal and/or uplink perceptual signal send downlink data signal in corresponding descending time slot and/or downlink perceive letter
Number, it may also be used for instruction terminal (i.e. this cell terminal) sends upstream data signals and/or uplink sense in corresponding ascending time slot
Know signal, downlink data signal and/or downlink perceptual signal are received in corresponding descending time slot.
Specifically, shown in Figure 5, for the free timeslot of acquiescence, terminal and base station are all kept on the free timeslot
Silence, dispatch terminal does not send or receives signal for base station, and terminal does not also send or receive signal.In this way, be conducive to save electricity consumption.
For being used for the Flexible timeslot of downlink, base station schedules terminals receive downlink data signal on the Flexible timeslot.
On the SP of the Flexible timeslot, base station sends downlink perceptual signal.The downlink perceptual signal can be the public affairs for indicating this cell
Pilot signal altogether, or the downstream modulation pilot signal of this cell terminal where being scheduled in the SP on time slot is used for
Interference between potential disturbed adjacent cell base station detection base station.
After terminal obtains scheduling information, downlink data signal is received on the Flexible timeslot, while in the Flexible timeslot
The uplink perceptual signal that adjacent cell terminal is sent is received on SP, to detect the adjacent cell terminal to the interference information of this terminal, tool
Body is shown in Figure 5.The interference information includes but not limited to：Interference power values, the cell ID of interfered with terminal, interfered with terminal
Directional information etc..In this way, this cell terminal is after the interference information is obtained, so that it may carry out interference deletion, Power Control, coordinate to adjust
Degree etc., to reduce the interference of terminal room, guarantee business more preferably carries out.
Wherein, in order to avoid the interference between this cell base station pilot tone and potential adjacent cell terminal pilot tone, when one is flexible
On the SP of gap, the frequency resource position that this cell base station sends downlink perceptual signal most preferably sends uplink perception with adjacent cell terminal
The frequency resource position of signal is orthogonal.
Optionally, base station can also send downlink data signal and downlink perceptual signal simultaneously in SP positions, and the downlink
Perceptual signal only takes up portion of time frequency resources.
For being used for the Flexible timeslot of uplink, base station schedules terminals send upstream data signals on the Flexible timeslot, and
Downlink data signal is received in corresponding time slot position.Meanwhile base station receives potential adjacent cell base on the SP of the Flexible timeslot
The downlink perceptual signal stood, to detect the adjacent cell base station to the interference information of this base station, referring specifically to shown in Fig. 5.The interference
Information includes but not limited to：Interference power values, the mark of interference base station, directional information of interference base station etc..In this way, this cell base
It stands after the interference information is obtained, so that it may interference deletion, Power Control, coordinated scheduling etc. are carried out, to reduce the interference between base station,
Guarantee business more preferably carries out.
After terminal obtains scheduling information, upstream data signals are sent on the Flexible timeslot, while in the Flexible timeslot
Uplink perceptual signal is sent on SP.The uplink perceptual signal can be the common pilot signal for indicating this cell, or quilt
The uplink demodulation pilot signal of this cell terminal where the perception cycle on time slot is dispatched, for potential adjacent cell terminal
Interference between detection terminal.
Wherein, in order to avoid the interference between this cell terminal pilot tone and potential adjacent cell base station pilot, when one is flexible
On the SP of gap, the frequency resource position that this cell terminal sends uplink perceptual signal most preferably sends downlink perception with adjacent cell base station
The frequency resource position of signal is orthogonal.That is, on the SP of a Flexible timeslot, the frequency resource of downlink perceptual signal is sent
Position is orthogonal most preferably with sending the frequency resource position of uplink perceptual signal.
Optionally, terminal can also send upstream data signals and uplink perceptual signal simultaneously in SP positions, and the uplink
Perceptual signal only takes up portion of time frequency resources.
The dispatching method of first embodiment of the invention adjusts the cycle by defining time slot, and the time slot adjustment cycle includes
At least three time slots and at least three time slot are divided into fixed descending time slot, fixed ascending time slot and Flexible timeslot, will
Each Flexible timeslot in the time slot adjustment cycle is arranged to descending time slot, ascending time slot or free timeslot, after setting
The type dispatch terminal of time slot in the time slot adjustment cycle, even if under the time slot type and frame structure of 5G complexity, it also can be real
The dynamic adjustment of existing time slot ratio, meets business demand, and effectively controls and manage the interference of minizone, and lifting system is handled up
Amount and user experience.

401~step 409, details are as follows.
Step 401：Define the time slot adjustment cycle.
In the embodiment of the present invention, time slot that base station the defines adjustment cycle may include at least three time slots, and this at least three
Time slot is divided into fixed descending time slot, fixed ascending time slot and Flexible timeslot.
Wherein, the above-mentioned explanation to step 301 can be found in the explanation of step 401, details are not described herein.
Step 402：Determine initial slot configuration information.
In the embodiment of the present invention, which is mainly used for representing the time slot in the time slot adjustment cycle
Type.Base station on startup, can be based on the network planning and Optimization Experience, configure an initial time slot configuration information.For example,
For the TDD system in the time slot adjustment cycle including 10 time slots, 2 fixed descending time slots (first and second are can configure
Time slot), 6 Flexible timeslots (the 3rd to the 8th time slot) and 2 fixed ascending time slots are (at first and second
Gap).
It should be noted that the initial slot configuration information can be with the default time slot configuration information one in base station system
It causes, it can also be inconsistent with the default time slot configuration information in base station system.
Step 403：The initial slot configuration information is sent to terminal.
In the embodiment of the present invention, base station can pass through system broadcasts when initial slot configuration information is sent to terminal
The initial slot configuration information is sent to terminal by information, dedicated radio resource control RRC signaling can also be utilized, by this
Initial slot configuration information is sent to terminal, the initial slot can also be matched somebody with somebody confidence by time slot configuration common control channel
Breath is sent to terminal.
Wherein, which is downlink common control channel.Passing through the public control of time slot configuration
Channel, when which is sent to terminal, in order to ensure that terminal can listen to the initial slot with confidence
Breath, need to be sent to terminal by the configuration information of the time slot configuration common control channel by system broadcast information.An in general, base
It stands and allows multiple time slot configuration common control channel, transmit different time slot configuration information respectively.One base station can have more
A transmission receiving node (Transmission Reference Point, abbreviation TRP), during the time slot configuration difference of each TRP
Scene.
In the embodiment of the present invention, which can utilize bit information, such as 2bits or 3bits to carry out
Instruction, indicating means are the type for adjusting each time slot in the cycle to output time slot by bit information order.
The type of the time slot can be it is following any one：Descending time slot with down control channel, band uplink control channel
Ascending time slot, self-contained descending time slot, self-contained ascending time slot, pure descending time slot, pure ascending time slot, fixed descending time slot,
Fixed ascending time slot and Flexible timeslot；But the present invention is not limited.
For example, with reference to the following table 1, initial slot configuration information is indicated using 2bits, the corresponding time slot adjustment cycle includes
10 time slots：
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| 01 | 01 | 00 | 00 | 00 | 00 | 00 | 00 | 10 | 10 |
Table 1
Wherein, the fixed descending time slot of 01 instruction, 00 instruction Flexible timeslot, the fixed ascending time slot of 10 instructions.And bit 11
For reservation types.
Referring back to the following table 2, initial slot configuration information is indicated using 3bits：
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| 001 | 101 | 111 | 000 | 000 | 000 | 000 | 011 | 110 | 010 |
Table 2
Wherein, 001 descending time slot of the instruction with down control channel, 101 instructions are not under the data with down control channel
Row time slot, the 111 self-contained descending time slots of instruction (i.e. self-contained downlink is main time slot), 000 instruction Flexible timeslot, 011 instruction
Self-contained ascending time slot (i.e. self-contained uplink is main time slot), 110 indicate the not ascending time slot with uplink control channel.And its
Remaining bit is reservation types.
According to above-mentioned Tables 1 and 2：With increasing for number of bits, denotable time slot type also increases.Work as
There are during the more time slot type to be indicated, it can suitably increase number of bits.
Step 404：Determine the indicating mode of time slot configuration fresh information.
In the embodiment of the present invention, the indicating mode of the time slot configuration fresh information can be explicit instruction mode or implicitly refer to
Show mode.Wherein, if explicit instruction mode, corresponding time slot configuration fresh information need to be sent to terminal by base station, and such as
Fruit is implicit instruction mode, and corresponding time slot configuration fresh information can not be sent to terminal by base station, and direct dispatch terminal.
In this way, under explicit instruction mode, terminal can know the type of Flexible timeslot before being scheduled, so, flexibly
Time slot is used as any kind of time slot, available for scheduling or self-contained etc.；And under implicit instruction mode, terminal is being adjusted
The type of Flexible timeslot is not known that before degree, scheduling can only be based on and learn a certain Flexible timeslot as downlink or uplink, so, spirit
Time slot living cannot be used for downlink to be dispatched for the first time.
Step 405：The information for characterizing the indicating mode is sent to the terminal by system broadcast information.
In the embodiment of the present invention, explicit instruction mode or implicit instruction mode that base station uses can pass through system broadcast information
Tell terminal.In this way, terminal is after the indicating mode for knowing time slot configuration fresh information is explicit instruction mode, so that it may monitor phase
The channel answered is to obtain time slot configuration fresh information.
It is pointed out that in practical application, step 402 and step 404 can perform simultaneously, step 403 and step 405
What transmission process also performed simultaneously.
Step 406：The time slot is adjusted into each Flexible timeslot in the cycle and is arranged to descending time slot, ascending time slot or free time
Time slot.
Specifically, can be found in the above-mentioned explanation to step 302 to the explanation of step 406, details are not described herein.
Step 407：When the indicating mode is explicit instruction mode, time slot configuration fresh information is determined.
In the embodiment of the present invention, which was mainly used in the time slot adjustment cycle after representing to set
The type of time slot,
Step 408：The time slot configuration fresh information is sent to the terminal.
In the embodiment of the present invention, base station can pass through system broadcasts when time slot configuration fresh information is sent to terminal
The time slot configuration fresh information is sent to terminal by information, dedicated radio resource control RRC signaling can also be utilized, by this
Time slot configuration fresh information is sent to terminal, the initial slot can also be matched somebody with somebody confidence by time slot configuration common control channel
Breath is sent to terminal.
Wherein, which is downlink common control channel, is usually located in the time slot adjustment cycle
First descending time slot.The configuration information of the time slot configuration common control channel can be sent to end by system broadcast information
End.In general, a base station allows multiple time slot configuration common control channel, different time slot configuration information is transmitted respectively.One
A base station can have multiple TRP, the asynchronous scene of time slot configuration (identical with initial configuration) of each TRP.
In the embodiment of the present invention, which can utilize bit information, such as 2bits or 3bits to carry out
Instruction, indicating means are to adjust the type of each time slot in the cycle to output time slot by bit information order (with initial slot
Configuration information is similar).
For example, with reference to the following table 3, time slot configuration fresh information is indicated using 2bits, the corresponding time slot adjustment cycle includes
10 time slots：
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| 01 | 01 | 01 | 01 | 00 | 00 | 00 | 10 | 10 | 10 |
Table 3
Wherein, 01 indicating downlink time slot, 00 instruction free timeslot, 10 instruction ascending time slots；Remaining bit is reserved class
Type.
Further, if the time slot type that is related to of the time slot configuration fresh information is more, number of bits can suitably be increased
It is indicated, similar to the indicating means of initial slot configuration information.
In addition, for the ease of the interference coordination of minizone, this cell base station can also be connect by cell interface such as X2
The time slot configuration fresh information is sent to adjacent cell base station or receives the time slot configuration update letter of adjacent cell base station transmission by mouth
Breath.
Step 409：The type of time slot and the time slot configuration information of adjacent cell in the cycle are adjusted based on the time slot after setting,
Scheduling information is sent to the terminal by down control channel.
In the embodiment of the present invention, for dispatch terminal, scheduling information can be transmitted to terminal in base station.
Wherein, the scheduling information cannot be only used for instruction base station corresponding ascending time slot receive upstream data signals and/
Or uplink perceptual signal, send downlink data signal and/or downlink perceptual signal in corresponding descending time slot, it may also be used for instruction
Terminal sends upstream data signals and/or uplink perceptual signal in corresponding ascending time slot, under the reception of corresponding descending time slot
Row data-signal and/or downlink perceptual signal.
Specifically, base station can consider the time slot configuration of this cell and the time slot of adjacent cell when sending scheduling information
Configuration.
For a Flexible timeslot, if this cell base station and adjacent cell base station all configure the Flexible timeslot as ascending time slot,
The scheduling information may indicate that this cell terminal, without the transmission of uplink perceptual signal, is completely used for uplink on the Flexible timeslot
The transmission of control channel and upstream data signals；If this cell base station and adjacent cell base station all configure the Flexible timeslot for downlink when
Gap, then the scheduling information may indicate that this cell terminal without the reception of downlink perceptual signal, is all used on the Flexible timeslot
In the transmission of down control channel and downlink data signal；If this cell base station configures, the Flexible timeslot is ascending time slot and neighbour is small
Area base station configures the Flexible timeslot as descending time slot, then the scheduling information may indicate that this cell terminal is sent on the Flexible timeslot
Uplink perceptual signal, the uplink perceptual signal detect the interference letter of this cell terminal for adjacent cell terminal on the Flexible timeslot
Breath；If this cell base station configures, the Flexible timeslot is descending time slot and to configure the Flexible timeslot be ascending time slot for adjacent cell base station,
Then the scheduling information may indicate that this cell terminal receives uplink perceptual signal on the Flexible timeslot, which is adjacent
What cell terminal was sent on the Flexible timeslot, the interference information of the adjacent cell terminal is detected for the terminal.
In addition, for same Flexible timeslot, if it is ascending time slot and adjacent cell that this cell base station, which configures the Flexible timeslot,
Base station configures the Flexible timeslot as descending time slot, then the scheduling information indicates that this cell base station connects on the Flexible timeslot
Row perceptual signal is accepted, the downlink perceptual signal is that the adjacent cell base station is sent on the Flexible timeslot, for institute
State the interference information that this cell base station detects the adjacent cell base station；If this cell base station configuration Flexible timeslot is downlink
Gap and adjacent cell base station configure the Flexible timeslot as ascending time slot, then the scheduling information indicates this cell base station in the spirit
Downlink perceptual signal is sent on time slot living, the downlink perceptual signal detects this for adjacent cell base station on the Flexible timeslot
The interference information of cell base station.
If it is pointed out that base station do not indicated in scheduling information the terminal for being scheduled for Flexible timeslot whether detect or
Person sends perceptual signal, then the terminal need to be the upper of reception adjacent cell terminal transmission in all descending time slots all detection senses signals
Row perceptual signal all sends uplink perceptual signal in all ascending time slots.
When adjacent time-slots are all used for the transmission of data-signal, if the adjacent time-slots for descending time slot to ascending time slot or
Ascending time slot need to reserve enough GP to descending time slot, the then transfer point of the adjacent time-slots, and the big I of the GP is by MPS process
The factors such as rate determine.
In the embodiment of the present invention, the down control channel for sending scheduling information may be disposed at fixed descending time slot or spirit
Time slot living.Specifically, under explicit instruction mode, since terminal has learned that the type of Flexible timeslot before being scheduled, so,
The down control channel can be arranged to the fixation descending time slot with down control channel and/or be arranged at downlink control
The Flexible timeslot for being arranged to descending time slot of channel processed；And under implicit instruction mode, since terminal can only be based on dispatching
Know the type of Flexible timeslot, so, when which can only be arranged to the fixation downlink with down control channel
Gap.
In this way, under explicit instruction mode, the less fixation descending time slot with down control channel is can configure, it will be more
Descending scheduling be put into follow-up Flexible timeslot, with play it is energy saving and reduce time-lag action；And under implicit instruction mode, it need to match somebody with somebody
