Wherein, Ts is that system uses time interval, and X is pre-defined or configuration value.

In LTE system, the division of up-downgoing resource is realized by the definition of tdd frame structure, therefore a LTE is small Area, can only configure a kind of tdd frame structure, then only supports fixed up-downgoing resource to divide, and be believed by the system broadcasted in cell Breath notice, therefore be to immobilize, it is that all terminals are shared in the cell.

In addition, it is up with in same cell to avoid that GP is needed in LTE system, between ascending resource and downlink resource Interference between row and the switching for realizing downstream-to-upstream.Special subframes of the GP only in above-mentioned each TDD uplink-downlink configurations Middle presence, GP length configure depending on special subframe, and a kind of special subframe configuration has just corresponded to the descending money in special subframe The length division in source (DwPTS parts), ascending resource (UpPTS parts) and GP parts.Special subframe configures in one cell And the notice of the system information by being broadcasted in cell, therefore be changeless, it is that all terminals are shared in the cell.

With the development and change of mobile communication business demand, ITU (International Telecommunication Union, International Telecommunication Union) and the group such as 3GPP (3rd Generation partnership project, 3 generation collaborative projects) Knit the new wireless communication system that all begins one's study (such as 5G systems).New wireless communication system can support multiple business type And deposit, such as eMBB (Enhanced Mobile Broadband, enhanced mobile Internet) business, URLLC (Ultra Reliable＆Low Latency Communication, ultrahigh reliability and ultralow time delay) business, mMTC (Massive Machine Type Communication, the Internet of Things of magnanimity connection) business etc., the portfolio of same business can also occur Change.When up-downgoing business shares same frequency range using TDM (Time Division Multiplexing, time division multiplexing) mode During resource, in order to support different service types and traffic needs, it is necessary to support the resource of flexibility and changeability to divide.

It can be seen that in future communication systems, ascending resource and downlink resource more can be divided dynamically, up-downgoing resource Between GP be also required to flexibly change to adapt to different demands.And in LTE system, the division of up-downgoing resource and GP configurations are all The exclusive configuration of cell, the terminal in the cell are all identical configurations, it is impossible to are flexibly become for terminal in future communication systems The type of service of change, portfolio, disturbed condition make dynamic adjustment.

Based on same inventive concept, in the embodiment of the present invention, end side such as Fig. 5 of the handling process in downlink transmission process It is shown, it is specific as follows：

Step 501：Terminal determines the descending test position in very first time unit.

Terminal determines that the concrete mode of the descending test position in very first time unit is identical with step 301 herein, specifically Embodiment can be found in the detailed description of step 301, be not repeated herein.

Step 502：Terminal by blind Detecting determine descender region corresponding with the descending test position and/or with it is described Up region corresponding to descending test position.

Specifically, terminal determines descender region corresponding with the descending test position by blind Detecting, and detailed process is： The reception of terminal detection signal on each symbol or mini-slot or the second time quantum since the descending test position Power, first receiving power is defined as to the rest position of the descender region less than the position of predetermined threshold value, under described Descending test position in N3 very first time unit or the lower start of line after row test position or the very first time unit Original position of the position as the descender region.

Specifically, terminal determines up region corresponding with the descending test position by blind Detecting, and detailed process is： The terminal detects down control channel since the descending test position, according to the down control channel or described detected The uplink feedback resource size and/or uplink shared channel resources size indicated in down control channel determines up region.

Such as the down control channel for using descending DCI format is detected, indicate carrying in the down control channel The size and location of ACK/NACK uplink feedback resource, the then region up region for corresponding to, or the down control channel In do not indicate loading ACK/NACK uplink feedback resource position, feedback position is true according to pre-defined feedback sequential Fixed, feedback resources size can be that the down control channel notifies, or pre-defined or configuration, then can also be true Up region corresponding to fixed；In another example detect the down control channel using up DCI format, the down control channel middle finger Ascending resource position and the size of Uplink Shared Channel are shown, then according to corresponding to can determining ascending resource of its instruction Up region.

Based on same inventive concept, in the embodiment of the present invention, handling process of the base station side in downlink transmission process such as Fig. 6 It is shown, it is specific as follows：

Step 601：Base station determines the descending test position in very first time unit.

Step 602：Base station determines up corresponding to the descending test position in very first time unit according to the actual requirements Region and/or descender region, and carry out corresponding data transmit-receive in corresponding region.

Specifically, base station sends downlink transfer, including hair in the descender region corresponding to descending test position to terminal Down control channel, the down control channel using up DCI format, the DSCH Downlink Shared Channel using descending DCI format are sent, this The rest position of all time-domain positions of a little channel occupancies is the rest position of the descender region, with descending test position or institute Descending test position in N3 very first time unit after very first time unit or descending original position are stated as under described The original position in row region；So, terminal is in the blind check signal since descending test position, in the descender region that base station determines In can always detect receiving power more than predetermined threshold value, so that it is determined that going out the descender that base station have sent downlink transfer Domain.

Specifically, when base station have sent the downlink transfer for needing progress ACK/NACK feedbacks in descender region (such as refer to Show the down control channel or DSCH Downlink Shared Channel of descending SPS resources release), then base station is corresponding to descending test position The uplink of receiving terminal in up region.Such as base station have sent the descending DCI of use for needing to carry out ACK/NACK feedbacks The down control channel of form, size and the position of loading ACK/NACK uplink feedback resource are indicated in the down control channel Put, then the region is corresponding up region, or loading ACK/NACK uplink feedback is not indicated in the down control channel The position of resource, the position of feedback resources are to determine that feedback resources size can be this according to pre-defined feedback sequential Down control channel notice, or pre-defined or configuration, then can also determine corresponding to up region；In another example base Station have sent the down control channel using up DCI format, and a Uplink Shared Channel is indicated in the down control channel Ascending resource position and size, then according to its instruction ascending resource can determine corresponding to up region.

Downlink transmission process provided in an embodiment of the present invention is described in detail below by way of two specific embodiments.

First specific embodiment

As shown in Figure 7, it is assumed that the length of a very first time unit is a time slot (slot), and a slot includes 7 OFDM symbol, a subframe (subframe) include 2 slot；Accorded with assuming that the length of second time quantum is an OFDM Number；And, it is assumed that the switching time of downstream-to-upstream is 20us, it is assumed that the length of an OFDM symbol is 66.7us.Need Bright, the value of each parameter described herein by way of example only, is not used to limit the span of each parameter, this hair Bright protection domain is not limited thereto system.

Base station side：

Base station determines a slot being divided into a up region and a descender region, up region and descender region Between for GP, where it is assumed that up region is fixed as a slot last OFDM symbol, it is assumed that descender region is opened Beginning, position was fixed as a slot first OFDM symbol, i.e., descending test position is fixed as a slot first OFDM Symbol.It should be noted that up-downgoing dividing mode described herein is by way of example only, protection scope of the present invention is not As limitation.

Base station is notified to above and below one slot of terminal by high-level signaling or in the configuration information that ad-hoc location is sent Row dividing mode.Wherein, the configuration information that the ad-hoc location is sent can periodically be sent, such as each slot or every Sent in top n OFDM symbol in individual subframe or multiple slot or multiple subframes, N value is more than or equal to 1.Or base It can also be the slot up-downgoing dividing mode of making an appointment to stand with terminal, without signaling.

In the specific embodiment, base station is according to step A or step B or combines step A and B, determines the current of present sub-frame GP sizes required in slot, and then the descender region size in the slot is determined, wherein, up area size is fixed, Specifically：

Step A：Base station determines the upstream data that how many individual terminals need to send in the up region in current slot be present, By the maximum conduct in Timing Advance (Timing Advance, TA) value of the terminal of each upstream data for needing to send For determining GP1 TA values；

Step B：Base station carries out adjacent area interferometry in the up region before current slot, obtains the strong of adjacent area interference Degree, determine the need for remaining for resisting the GP2 disturbed adjacent area in advance in GP parts according to the intensity, base station can be according to the GP2 The descender region of this cell is adjusted, or GP2 is notified while base station can adjust the descender region of this cell according to the GP2 To the neighbor base station belonging to the interference measured, the upstream or downstream region by the neighbor base station according to GP2 adjustment adjacent area, with Adjacent area is avoided to disturb, or base station can also be it is determined that do not consider GP2 when this cell GP and descender region, and directly lead to GP2 Know the neighbor base station belonging to the interference measured, at least adjust the descender region of adjacent area according to the GP2 by the neighbor base station, with Avoid the interference up to local area of the descender region of adjacent area.

In first embodiment, if only determining (such as base station prejudges no adjacent area and disturbed) according to step A, base station is not Need execution step B process, it is only necessary to the GP1 obtained according to step A, determine the integer OFDM symbol conduct of meet demand Actual GP, it is assumed for example that determine that maximum TA is 45us according to step A, it is determined that GP1 length is 45us, it is also necessary to reserved 20us's Switching time, then reserved 65us is needed, is rounded up, it is necessary to which 1 OFDM symbol is as actual GP, so that it is determined that going out descender region For 5 OFDM symbol sizes, i.e. the 1st~5 OFDM symbol is descender region.

In second embodiment, if only determining (such as base station prejudges no TA) according to step B, base station need not be held Row step A process, it is only necessary to the GP2 obtained according to step B, determine the integer OFDM symbol of meet demand as actual GP, it is assumed for example that the strong jamming for determining to have more than threshold value according to step B, and strongly disturbing persistence length is 75us, then really It is 75us to determine GP2 length, it is also necessary to reserved 20us switching time, then needs reserved 95us, rounds up, it is necessary to 2 OFDM Symbol is as actual GP, so that it is determined that it is 4 OFDM symbol sizes to go out descender region, i.e. the 1st~4 OFDM symbol is descender Domain.

In 3rd embodiment, if determined according to step A and B simultaneously, according to GP1+GP2, meet demand is determined Integer OFDM symbol is as actual GP, it is assumed for example that determines that GP1 length is 45us according to step A, GP2 is determined according to step B Length is 75us, it is also necessary to reserved 20us switching time, then needs reserved 150us altogether, rounds up, it is necessary to 3 OFDM symbols Number actual GP of conduct, so that it is determined that it is 3 OFDM symbol sizes to go out descender region, i.e. the 1st~3 OFDM symbol is descender Domain.

Wherein, for any one in the first to the 3rd embodiment, it is determined that GP1 and/or GP2 value may also For 0, such as up region is not present terminal and needs to send upstream data, then GP1=0, interferometry do not measure strong jamming, then GP2=0.

Base station sends downstream signal 1 in the specific resources in current slot, notify terminal should by the downstream signal 1 Descender region size in slot, GP sizes are notified of so as to be implied in the case of the fixation of up area size, or passed through The downstream signal 1 directly notifies the GP sizes of the above-mentioned determination of terminal, logical so as to be implied in the case of the fixation of up area size The size of cicada descender region；Assuming that downstream signal 1, which only takes up 1 OFDM symbol transmission, (wherein takes A OFDM symbol transmission Method it is similar, be only changed into a slot preceding A OFDM symbol as descending test position), base station is in each slot First OFDM symbol on send downstream signal 1 and (can take fixed frequency domain position, or if be carried on descending control letter In road, then it is defined in search space and sends according to the search space of down control channel, down control channel can be to use The down control channel of descending DCI format, which can be that all terminals or part terminal are shared or terminal is exclusive, to be held Carry the down control channel of descending scheduling signaling；Certain downstream signal 1 can also similar broadcast mode in specific resources according to Fixed form is sent, unrelated with data dispatch relation or feedback relationship).

In the specific embodiment, base station repeats the above method to each slot in each subframe, needed for different slot GP length may be different, therefore the descender region size indicated by downstream signal 1 may be different.

In the specific embodiment, base station is sent in each slot descender region uses descending DCI (Downlink Control Information, Downlink Control Information) form down control channel, and sent in the descender region under this DSCH Downlink Shared Channel scheduled in row control channel, further in the ACK/NACK feedbacks of the corresponding carrying DSCH Downlink Shared Channel Up region (the up region can arrange or configure or be designated as the up region in current slot, can also arrange or Configure or be designated as the up region in next slot, in Fig. 7 only using corresponding relation as current slot in up region be Example) receive ACK/NACK feedbacks；Base station sends the down control channel using up DCI format in a descender region, and In the up region scheduled in the down control channel (during the up region can arrange or configure or be designated as current slot Up region, can also arrange or configure or be designated as the up region in next slot, in Fig. 7 only using corresponding relation as work as Exemplified by up region in preceding slot；In addition, the descending control using descending DCI format sent in same descender region Up region where the ACK/NACK feedback transmissions of DSCH Downlink Shared Channel scheduled in channel, with using up DCI format The up region where Uplink Shared Channel transmission scheduled in down control channel can be with identical, can also be different) in reception Row shared channel.

End side：

Terminal receives high-level signaling or receives configuration information in ad-hoc location, and specifically, terminal can be periodic Receive the high-level signaling or the configuration information.Terminal obtains the descending test position in each slot carried in the high-level signaling With up partition information, or, terminal obtain descending test position in each slot carried in the configuration information and Up partition information；Certainly, terminal can also be according to make an appointment obtain descending test position in each slot and Up partition information, without receiving high-level signaling or configuration information.

Terminal receives downstream signal 1 in subframe i slot0 specific resources, so as to obtain the descender in the slot Domain size；Assuming that downstream signal 1 only take up the transmission of 1 OFDM symbol (it is similar wherein to take the method that A OFDM symbol is transmitted, Only it is changed into a slot preceding A OFDM symbol as descending test position), first OFDM of the terminal in each slot Downstream signal 1 is received on symbol, and (downstream signal 1 can take fixed frequency domain position, or if the downstream signal 1 is carried on In down control channel, then it is defined in search space and detects according to the search space of down control channel, down control channel It can be the down control channel using descending DCI format, can be that all terminals or part terminal are shared or whole Hold the down control channel of exclusive bearing downlink dispatch；Certain downstream signal 1 can also be similar to broadcast mode specific Sent in resource according to fixed form, unrelated with data dispatch relation or feedback relationship), sent according to base station sending side identical Mode determines descender region size, big in UL regions if downstream signal 1 directly notifies the descender region size in the slot It can be implied according to the descender region size in the case of small fixation and determine GP sizes, or if downstream signal 1 directly notifies The GP sizes of above-mentioned determination, then it can be implied according to GP sizes in the case where UL area sizes are fixed and determine the big of descender region It is small.

In implementation, each slot in each subframe of terminal-pair repeats the above method, so that it is determined that under in each slot Row area size, the descender region size in different slot may be different.

Terminal detects down control channel in the descender region of each slot determination, and descending DCI is used when detecting During the down control channel of form, the DSCH Downlink Shared Channel scheduled in the down control channel is received, further in the descender (the up region can arrange or configure or be designated as and be current in the up region for being used to carry out ACK/NACK feedbacks corresponding to domain Up region in slot, it can also arrange or configure or be designated as the up region in next slot, only with corresponding in Fig. 7 Exemplified by relation is the up region in current slot) transmit the ACK/NACK feedback informations of the DSCH Downlink Shared Channel；When detecting Using up DCI format down control channel when, in the up region scheduled in the down control channel, (the up region can To arrange or configure or be designated as the up region in current slot, it can also arrange or configure or be designated as in next slot Up region, in Fig. 7 only so that corresponding relation is the up region in current slot as an example；In addition, in same descender region The ACK/NACK feedback transmissions institute of DSCH Downlink Shared Channel scheduled in the down control channel using descending DCI format of middle transmission Up region, with using up DCI format down control channel scheduled in Uplink Shared Channel transmission where it is upper Row region can be with identical, can also be different) transmission Uplink Shared Channel.

In the specific embodiment, if a slot includes 2 up regions and two descending test positions, such as Fig. 8 institutes Show, specific base station is similar with terminal implementation process, and only base station needs each descending detecting position being directed in each slot Put and send downstream signal 1, indicate the descender region size that the descending test position starts, terminal needs more in a slot Individual descending test position receives downstream signal 1, obtains the descender region size that the descending test position starts；When assuming that one When one time quantum is a subframe or other times unit, similarly.

Second specific embodiment

As shown in Figure 9, it is assumed that the length of a very first time unit is a slot, and a slot includes 7 OFDM and accorded with Number, a subframe (subframe) includes 2 slot；Assuming that the length of second time quantum is an OFDM symbol；It is false If the switching time of downstream-to-upstream is 20us, it is assumed that an OFDM symbol length is 66.7us；It should be noted that this place The value of each parameter of description by way of example only, is not used to limit the span of each parameter, protection scope of the present invention It is not limited thereto system.

Base station side

Base station side determines a slot being divided into a up region and a descender region, up region and descender It is GP between domain, where it is assumed that descender region is fixed as a slot preceding 2 OFDM symbols, then the start bit of descender region Put first OFDM symbol (i.e. descending test position) for being fixed as a slot, it is assumed that the rest position in up region is one Slot last OFDM/SC-FDMA symbol, certainly herein by way of example only, protection scope of the present invention is not with this For limitation, other up-downgoing dividing modes are similar with this implementation implementation process, and here is omitted.

Base station notifies the up-downgoing to terminal slot to draw by high-level signaling or in the configuration information that ad-hoc location is sent The configuration information that the mode of dividing, wherein ad-hoc location are sent can periodically be sent, such as each slot or each subframe Or sent in the top n OFDM symbol in multiple slot or multiple subframes, N is 1 or 2；Can certainly be that terminal and base station are pre- First arrange the up-downgoing dividing mode without signaling.

In the specific embodiment, base station is according to step A or step B or combines step A and B, determines the current of present sub-frame GP sizes required in slot, and then the up area size in the slot is determined, descender region size is fixed.Specifically Ground：

Step A：Base station determines that how many individual terminals in the up region in current slot be present needs to send upstream data, takes Each maximum for needing to send in the TA values of the terminal of upstream data is as the TA values for determining GP1；

Step B：Base station carries out adjacent area interferometry in the up region before current slot, obtains the strong of adjacent area interference Degree, determine the need for being used to resist the GP2 disturbed adjacent area in GP parts reserved area according to the intensity, base station can be according to this GP2 adjusts the up region of this cell, and base station leads to GP2 while the up region of this cell can also be adjusted according to the GP2 Know the neighbor base station belonging to the interference measured, adjust the upstream or downstream region of adjacent area according to the GP2 by the neighbor base station, with Adjacent area is avoided to disturb, or base station can also be it is determined that do not consider GP2 when this cell GP and up region, and directly lead to GP2 Know the neighbor base station belonging to the interference measured, at least adjust the descender region of adjacent area according to the GP2 by neighbor base station, to avoid The interference up to local area of the descender region of adjacent area.

In first embodiment, if only determining (such as base station prejudges no adjacent area and disturbed) according to step A, base station is not Need execution step B process, it is only necessary to the GP1 obtained according to step A, determine the integer OFDM/SC-FDMA of meet demand Symbol is as actual GP, it is assumed for example that according to step A, it is determined that maximum TA is 45us, it is determined that GP1 length is 45us, it is also necessary to Reserved 20us switching time, then reserved 65us is needed, rounded up, it is necessary to using 1 OFDM symbol as actual GP, so as to really It is 4 symbol sizes to make up region, i.e. the 4th~7 OFDM/SC-FDMA symbol is up region.

In second embodiment, if only determining (such as base station prejudges no TA) according to step B, base station need not be held Row step A process, it is only necessary to the GP2 obtained according to step B, determine that the integer OFDM/SC-FDMA symbols of meet demand are made For actual GP, it is assumed for example that according to step B, it is determined that the strong jamming more than threshold value be present, and strongly disturbing persistence length is 75us, it is determined that GP2 length is 75us, it is also necessary to reserved 20us switching time, then need reserved 95us, round up, need 2 OFDM symbols are wanted as actual GP, so that it is determined that it is 3 symbol sizes, i.e. the 5th~7 OFDM/SC- to go out up region FDMA symbols are descender region.
