Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

It should be noted that scheme provided by the present invention is following, can be adapted for ascending-descending subframes, transmission block, burst (burst) etc. in the communication system being misaligned.Therefore, the present invention is using uplink transmission time unit as sub-frame of uplink, transmission The general designation of block, burst etc., is corresponding to it, and the present invention uses general designation of the downlink times unit as downlink subframe etc..

Core of the invention thought is, according to the relationship of uplink and downlink transfer, to determine the upper of transmission uplink signal The downlink times unit of row transmission time unit and transmission of downlink signal.

Based on above-mentioned core concept, the present invention provides transmission timing method and device.

Above-mentioned transmission timing means concretely eNB or UE.Transmit execution master of the timing means as transmission timing method Body, universal computer architecture include at least one processor 101, such as CPU, at least one network interface as shown in Figure 1: 104 or other users interface 103, memory 105, at least one communication bus 102.Communication bus 102 is for realizing these Connection communication between component.The transmission timing means 100 includes optionally keyboard or pointing device, for example, mouse, track Ball (trackball) etc..In embodiments of the present invention, the application program 1051 that processor 101 is stored by calling memory 105 Or instruction, execute each step in transmission timing method.

Referring to fig. 2, (uplink) transmission timing method performed by eNB may include following steps:

S21, according to the relationship of uplink and downlink transfer, determine the uplink transmission time unit of transmission uplink signal；

S22, it receives in uplink signal that is determining, being transmitted on uplink transmission time unit.

Fig. 3 is referred to, is corresponded, (uplink) transmission timing method may include following steps performed by UE:

S31, according to the relationship of uplink and downlink transfer, determine the uplink transmission time unit of transmission uplink signal；

S32, uplink signal is sent on determining, uplink transmission time unit.

Referring to fig. 4, (downlink) transmission timing method performed by eNB may include following steps:

S41, according to the relationship of uplink and downlink transfer, determine the downlink times unit of transmission of downlink signal；

S42, downlink signal is sent on determining downlink times unit.

Fig. 5 is referred to, (downlink) transmission timing method may include following steps performed by UE:

S51, according to the relationship of uplink and downlink transfer, determine the downlink times unit of transmission of downlink signal；

The downlink signal that S52, reception are sent on determining downlink times unit.

The relationship of above-mentioned uplink and downlink transfer may include, when the duration and downlink transfer of uplink transmission time unit Between unit duration between ratio (m), alternatively, the ratio (m) between downlink sub-carrier interval and uplink sub-carrier interval.m For the natural number greater than 1, for example, m can be equal to 2,5,8,10 etc..

It should be pointed out that the relationship that time and frequency are reciprocal each other, therefore, from time domain, if uplink The duration ratio of time quantum and downlink times unit is m, then from the point of view of frequency domain, uplink sub-carrier interval and downlink are carried Ratio between wave spacing is 1/m, that is, the ratio between downlink sub-carrier interval and uplink sub-carrier interval is m.

It will be understood by those skilled in the art that the duration ratio of uplink transmission time unit and downlink times unit is There are many implementations by m, such as:

Uplink transmission time unit may include a sub-frame of uplink, and downlink times unit may include downlink Frame, also, the duration ratio of the duration of sub-frame of uplink and downlink subframe is m, in this way, uplink transmission time unit and downlink pass The duration ratio of defeated time quantum is m.

Alternatively, uplink transmission time unit may include a transmission block, a transmission block includes m subframe again, and downlink Transmission time unit may include a subframe.In this way, the duration ratio of uplink transmission time unit and downlink times unit It also is m.

It should also be noted that, uplink signal may include perhaps having under different communication systems, different scenes in different Different addresses.For example, uplink signal, can be in uplink PUSCH channel under different scenes in LTE system Data (upstream data), in ack/nack signal of uplink PUCCH channel etc..Similarly, downlink signal is in different communication It also may include different interior perhaps having different addresses under system, different scenes.For example, downlink signal is not in LTE system With under scene, can in the data (downlink data) of downlink PDSCH channel, in downlink PHICH channel Ack/nack signal, the DCI transmitted on PDCCH/EPDCCH etc..

It is different now to provide a kind of uplink and downlink subframe lengths for technical solution provided by the embodiment of the present invention for ease of understanding Scene:

Covering is the key index of a communication system.Usually, the covering of a cell refers to given service rate Transmission range or area.During communication signal transmissions, large-scale fading, shadow fading, multipath fading can be undergone With penetration loss etc..With the increase of distance, signal can constantly decay, therefore enhancing covering is examined needed for improving system performance The key element considered.

System for sending power limited, a kind of mode of enhancing covering are the transmission bandwidths of reduction signal.Such as it is right In LTE system, subcarrier spacing 15kHz, if the subcarrier spacing of uplink is reduced to 1.25kHz, identical It sends under power, the power spectral density of uplink has the raising of 10.8dB, it is contemplated that covering will improve about 9-10dB.

Due to time and frequency relationship reciprocal each other, the phase of transmission symbol in time can be brought by reducing subcarrier spacing To extension, such as the subcarrier spacing of 1.25KHz, the symbol lengths of uplink SC-FDMA are 0.8ms, if adding 0.2ms CP(CP can be shorter, take 0.2ms convenient for design), then symbol lengths are 1ms.

And the UE that downlink is all due to cell to be served, reducing subcarrier spacing will lead to off-capacity, consider further that It may need to keep existing subcarrier spacing and structure constant with reasons, downlinks such as existing system compatibilities, therefore, the symbol of downlink The case where length remains as (1/14) ms, in such a scenario, refers to Fig. 6, and uplink and downlink symbol (subframe) is by being misaligned. Certainly, this is different one of the scene of ascending-descending subframes length, and under different needs, uplink and downlink subframe lengths are misaligned It may be there are many situation.

In the following, by being introduced by taking scene shown in fig. 6, under LTE as an example.

It should be noted that be involved in natural number Q and two nouns: uplink passes in the technical solution of following introductions Defeated reference time unit and downlink transfer reference time unit.

It is introduced in technical solution following, the beginning of downlink transfer reference time unit and uplink reference time unit Moment aligns.More specifically, by taking the different scene of the uplink and downlink subframe lengths under LTE as an example, Fig. 7, downlink transfer are referred to Reference time unit is downlink subframe n, and uplink reference time unit is sub-frame of uplink k.

As for natural number Q, it is contemplated that delay can enable Q be equal to 4.Certainly, those skilled in the art can carry out the value of Q Flexible design can also enable Q be equal to 2,3,5 etc., and therefore not to repeat here.

Such as without Special Statement, following downlink subframe n referred to refer both to downlink transfer reference time unit herein, and uplink is sub Frame k refers both to uplink reference time unit, and Q value is 4.

Scene will be divided to be introduced below.

Scene one, the scheduling for uplink PUSCH.

In this scene, " the uplink transmission time unit for determining transmission uplink signal " in above-mentioned steps S21 or S31 can Include:

To earlier than downlink subframe n, the 4th to m+3(namely m+Q-1) in a downlink subframe (downlink times unit) The uplink scheduling information of transmission determines that the uplink transmission time unit for transmitting corresponding uplink signal (upstream data) is sub-frame of uplink k。

Uplink scheduling information can be carried by uplink scheduling signaling (UL_Grant) or DCI.

It should be noted that referring to Fig. 8, earlier than downlink subframe n, the 4th to m+3 downlink subframe, also referred to as Downlink subframe (n-4) to (n-m-3).Therefore, in the present embodiment, downlink subframe (n-4) to (n-m-3) can correspond to uplink Frame k.Or it also is understood as: in downlink subframe (n-4) to (n-m-3) interior dispatching uplink subframe k.

As for sub-frame of uplink (k-1), it can analogize, m downlink subframe before corresponding downlink subframe (n-m-3).It is practical On, since each sub-frame of uplink all can be corresponding with a downlink subframe, each sub-frame of uplink all can be considered sub-frame of uplink k。

More specifically, location information of the above-mentioned uplink scheduling information in downlink subframe (n-4) to (n-m-3) can be pre- The value (such as pre-specified in the protocol) first set, alternatively, uplink scheduling information is at downlink subframe (n-4) to (n-m-3) Interior location information can also be determined according to message/UE ID.

It is sent out that is, above-mentioned uplink scheduling information can be fixed on subframe A in some in downlink subframe (n-4) to (n-m-3) It send, or can also say, some in downlink subframe (n-4) to (n-m-3), which is fixed, dispatches sub-frame of uplink k on subframe A.Such one Come, the scheduling for sub-frame of uplink k, UE only needs to monitor above-mentioned fixed subframe A.

Certainly, it is also designed to, uplink scheduling information is not secured on a certain downlink subframe and sends.In this way, UE needs It monitors downlink subframe (n-4) to (n-m-3).In the case where more UE, for a UE, at downlink subframe (n-4) to (n-m-3) It inside at most can only once uplink scheduling.

The concrete mode that location information is determined according to message is explained below.

In other embodiments of the present invention, the message in above-mentioned all embodiments can carry numerical value X or Z.The value range of X It can be 0 to m-1 or 1 to m, and the value of Z can be 4 to m+3；

When the value range of X is 0 to m-1, above-mentioned location information is (m+3-X), for characterizing, earlier than downlink transfer Reference time unit, on the m+3-X downlink times unit transmit above-mentioned uplink scheduling information.That is, referring to figure 9, above-mentioned uplink scheduling information is transmitted on downlink subframe (n-m-3+X).For example, as X=0, the position of uplink scheduling information It sets on downlink subframe (n-m-3), and as X=m-1, the position of uplink scheduling information is on downlink subframe (n-4).

Alternatively, above-mentioned location information is (4+X) when the value range of X is 0 to m-1, passed for being characterized in earlier than downlink Defeated reference time unit, on (4+X) a downlink times unit transmit uplink scheduling information；That is, referring to Figure 10, Above-mentioned uplink scheduling information is transmitted on downlink subframe (n-4-X).For example, as X=0, the position of uplink scheduling information exists On downlink subframe (n-4), and as X=m-1, the position of uplink scheduling information is on downlink subframe (n-m-3).

As shown in Figure 9, downlink subframe A may actually be downlink subframe (n-m-3+X), and be later than downlink subframe A, (m+3-x) a downlink subframe is then downlink subframe n, and sub-frame of uplink corresponding to downlink subframe n is sub-frame of uplink k.So as to It realizes, some in downlink subframe (n-4) to (n-m-3) fixes subframe up-regulation degree sub-frame of uplink k.

Certainly, X can also be used for characterizing, the uplink scheduling information sent on downlink subframe A, and corresponding upstream data is It is sent on being later than sub-frame of uplink corresponding to downlink subframe A, the 4+X downlink subframe.

As shown in Figure 10, downlink subframe A may actually be downlink subframe (n-4-X), and be later than downlink subframe A, 4+X downlink subframe is then downlink subframe n.Sub-frame of uplink corresponding to downlink subframe n is sub-frame of uplink k, thus also can be real Existing, some in downlink subframe (n-4) to (n-m-3) fixes subframe up-regulation degree sub-frame of uplink k.

As for when the value range of X is 1 to m, above-mentioned location information can be m+4-X(namely m+Q-X), for being characterized in Earlier than downlink transfer reference time unit, on the m+4-X downlink times unit transmit uplink scheduling information.That is, Above-mentioned uplink scheduling information is transmitted on downlink subframe (n-m-4+X).For example, as X=1, the position of uplink scheduling information On downlink subframe (n-m-3), as X=m, the position of uplink scheduling information is on downlink subframe (n-4).

Alternatively, in other embodiments of the present invention, when the value range of X is 1 to m, X can be used for characterizing, downlink subframe A The uplink scheduling information of upper transmission, corresponding upstream data are to be later than downlink subframe A, (m+4-x) a downlink It is sent on sub-frame of uplink corresponding to frame.

According to foregoing description, downlink subframe A may actually be downlink subframe (n-m-4+X).Then it is later than downlink subframe A , (m+4-x) a downlink subframe, then be downlink subframe n, sub-frame of uplink corresponding to downlink subframe n is sub-frame of uplink k. To can also realize, some in downlink subframe (n-4) to (n-m-3) fixes subframe up-regulation degree sub-frame of uplink k.

Certainly, X can also be used for characterizing, the uplink scheduling information sent on downlink subframe A, and corresponding upstream data is It is sent on being later than sub-frame of uplink corresponding to downlink subframe A, the 3+X downlink subframe.

According to foregoing description, downlink subframe A may actually be downlink subframe (n-3-X), then be later than downlink subframe A, The 3+X downlink subframe is then downlink subframe n, and sub-frame of uplink corresponding to downlink subframe n is sub-frame of uplink k.To also may be used It realizes, some in downlink subframe (n-4) to (n-m-3) fixes subframe up-regulation degree sub-frame of uplink k.

It is then location information as Z.For being characterized in earlier than downlink transfer reference time unit, Z or (m + 3-Z) above-mentioned uplink scheduling information is transmitted on a downlink times unit.That is, in downlink subframe (n-m-3+Z) or downlink Uplink scheduling information is transmitted in subframe (n-Z).

Above-mentioned message may include broadcast message, high-level signaling (such as RRC signaling) or physical layer signaling.

It should be noted that broadcast message, high-level signaling (such as RRC signaling) or physics can be passed through in more UE Layer signaling, distributes to different UE to (n-4) for downlink subframe (n-m-3), that is, dispatching on different downlink subframes different UE avoids the congestion of DCI to evenly distributing the DCI of same time slot on m downlink subframe.

In addition, the ID according to UE determines location information, it can also realize that the DCI by same time slot is evenly distributed in m downlink In subframe.The concrete mode that location information is determined according to the ID of UE is explained below.

In embodiments of the present invention, it can determine that location information is m+4-B or 3+B according to B=(n_UEID mod m)+1. N_UEID indicates that the ID of UE, " n " therein indicate English nomber(No.).N_UEID is distributed by base station.

Above-mentioned " mod " indicates complementation, and since divisor is m, then the value range of B is 1 to m.

Location information is m+4-B or 3+B, for characterizing, earlier than downlink transfer reference time unit, m+4-B Or uplink scheduling information is transmitted on the 3+B downlink times unit.That is, on downlink subframe (n-m-4+B) or under Above-mentioned uplink scheduling information is transmitted in row subframe (n-3-B).

Alternatively, can also determine that location information is m+3-B or 4+B according to B=n_UEID mod m.M+3-B or 4+B are used for Characterization is transmitted on earlier than downlink transfer reference time unit, m+3-B or the 4+B downlink times unit Row scheduling information.That is, transmitting above-mentioned uplink scheduling letter on downlink subframe (n-m-3+B) or on downlink subframe (n-4-B) Breath.

It should be noted that as the length of uplink dispatch (UL_Grant) or DCI in time is greater than a subframe (for example being 4 subframes), then " in certain subframe dispatch sub-frame of uplink k " described herein refer to using the subframe as Beginning subframe terminates subframe, transmits uplink scheduling signaling or DCI.And if the length of uplink scheduling signaling or DCI in time Within a subframe, then refers to and transmit uplink scheduling signaling or DCI in the subframe.

It should be noted that then eNB also needs to be implemented following steps as using location information is determined according to message:

Send the message for carrying numerical value X or Z.

It in other embodiments of the present invention, can also pre-specified X or Z in the protocol.In addition, in other implementations of the present invention In example, above-mentioned preset value, value can also be 4 to m+3.

Scene two, uplink feedback HARQ-ACK(ACK/NACK signal).

For the downlink data of eNB transmission, UE needs to feed back corresponding ascending HARQ-ACK.

To on determining that transmission is corresponding earlier than downlink subframe n, the downlink data that transmits in the 4th to m+3 downlink subframe The uplink transmission time unit of row HARQ-ACK signal is sub-frame of uplink k.

It is preceding to have addressed, extremely earlier than downlink subframe n, the 4th to m+3 downlink subframe, also referred to as downlink subframe (n-4) (n-m-3).Therefore, referring to Figure 11, it is above-mentioned " to earlier than downlink subframe n, transmitted in the 4th to m+3 downlink subframe under Row data determine that the uplink transmission time unit for transmitting corresponding ascending HARQ-ack signal is sub-frame of uplink k ", are also equal to: right Corresponding ascending HARQ-is transmitted in the downlink data transmitted in downlink subframe (n-4) to (n-m-3), determination on sub-frame of uplink k Ack signal.

In other words, the downlink data transmitted on downlink subframe (n-4) to (n-m-3), corresponding ascending HARQ-ACK Signal all transmits on sub-frame of uplink k.

It should be noted that being described in the technical solution for scene one, for downlink subframe (n-4) to (n-m- 3) uplink scheduling information transmitted in, transmits corresponding upstream data on sub-frame of uplink k.And in this scene, in downlink The downlink data transmitted in subframe (n-4) to (n-m-3), corresponding ascending HARQ-ack signal are also uploaded in sub-frame of uplink k It is defeated.In this way, on sub-frame of uplink k, possible simultaneous transmission upstream data and ascending HARQ-ack signal.Currently existing scheme in LTE It can support simultaneous transmission upstream data and ascending HARQ-ack signal, therefore, details are not described herein.

In specific implementation, can be prespecified in the protocol, the downlink transmitted on downlink subframe (n-4) to (n-m-3) Data, corresponding ascending HARQ-ack signal, are transmitted on sub-frame of uplink k.

To the upstream data transmitted on sub-frame of uplink k, the downlink transfer for transmitting corresponding downlink HARQ-ACK signal is determined Time quantum are as follows: be later than downlink subframe n, the m+3 downlink subframe.

It should be noted that referring to Figure 12, be later than downlink subframe n, the m+3 downlink subframe, also referred to as under Row subframe n+m+3.Therefore, in the present embodiment, for the upstream data transmitted on sub-frame of uplink k, in downlink subframe n+m+3 Upper feeding back downlink HARQ-ACK.

And the feeding back downlink HARQ-ACK on downlink subframe n+m+3 why is selected, it is to be because HARQ-ACK is determined No re-transmission data.Therefore, downlink HARQ ACK will at least wait upstream datas biography to be over and could feed back.So referring to Figure 13, Before downlink subframe n+m-1, it is unable to feeding back ACK/NACK signal.Again plus place of the time of 4 subframes as upstream data The time is managed, then n+m-1+4=n+m+3, thus selection feeding back downlink HARQ-ACK on downlink subframe n+m+3.It is implementing When, those skilled in the art can as needed the design treatment time, therefore not to repeat here.

In other embodiments of the present invention, in above-mentioned all embodiments " when determining the downlink transfer of transmission of downlink signal Between unit " (step rapid S41 or S51) also can include:

Determine that the Y downlink times unit for being later than uplink scheduling time quantum is, transmission downlink ACK/NACK letter Number downlink times unit.

Above-mentioned uplink scheduling time quantum is the downlink times unit for transmitting corresponding uplink scheduling information.And Y takes Value, can be m+2Q-1 or 2*(m+Q-1).In Q=4, m+2Q-1 is equal to m+7, as 2*(m+Q-1) it is equal to 2m+6.

It should be noted that (n-4) subframe downlink transfer uplink scheduling information is fixed in existing LTE system, in n Subframe uplink transmits upstream data.And Y value is (m+7), is in order to mutually compatible with existing LTE system.In this way, eNB can be under Downlink HARQ-ACK corresponding with uplink scheduling information is fed back in row subframe (n+m+3).

And 2m+6 is taken for Y, it can mutually be echoed with technical solution provided by scene one:

It is preceding to have addressed, uplink scheduling information can be transmitted in downlink subframe (n-4) to (n-m-3), then referring to Figure 12, if Y Value is 2m+6, then for the uplink scheduling information transmitted on downlink subframe (n-m-3), UE transmits uplink number in k subframe Corresponding downlink HARQ-ACK(referring to Figure 14 is fed back on downlink subframe (n+m+3) according to, eNB).

And the uplink scheduling information for transmitting on downlink subframe (n-4), UE transmit upstream data in k subframe, eNB Corresponding downlink HARQ-ACK is then fed back on downlink subframe (n+2m+2).In this way, can be by a large number of users on same downlink subframe k Upstream data corresponding to ACK/NACK feedback, be dispersed on downlink subframe (n+m+3) to (n+2m+2), solve The capacity problem of PHICH.

In specific implementation, can pre-specified Y in the protocol value, alternatively, carrying Y in the message.Above-mentioned message It may include broadcast message, high-level signaling (such as RRC signaling) or physical layer signaling.
