Description

A kind of ascending transmission method and device

Technical field

The present invention relates to communication technical field, more particularly to a kind of ascending transmission method and device.

Background technology

Existing LTE FDD (FDD) system uses frame structure (frame structure type 1, abbreviation FS1), Its structure is as shown in Figure 1.In FDD system, uplink and downlink transmission uses different carrier frequencies, on Row and downlink transfer use identical frame structure.On each carrier, the radio frames bag of a 10ms length Containing 10 1ms subframes, it is divided into the time slot of 0.5ms length in each subframe again, uplink and downlink data are sent TTI when a length of 1ms.

Existing LTE TDD (time division duplex) system uses frame structure (frame structure type 2, abbreviation FS2), its structure is as shown in Figure 2.In a tdd system, uplink and downlink transmission is used in identical frequency Different subframes or different time-gap.Each 10ms radio frames are made up of two 5ms fields in FS2, each field In the subframe comprising 5 1ms length.Subframe in FS2 is divided into three classes：Descending sub frame, sub-frame of uplink and Special subframe, each special subframe by downlink transfer time slot (DwPTS, Downlink Pilot Time Slot), Protection interval (GP, Guard Period) and upstream transmission time slot (UpPTS, Uplink Pilot Time Slot) Three parts are constituted.Wherein, DwPTS can transmit descending pilot frequency, downlink service data and descending control signaling； GP does not transmit any signal；UpPTS only transmits Stochastic accessing and detection reference signal (SRS, Sounding Reference Symbol), it is impossible to transmit uplink service or ascending control information.At least 1 is included in each field Individual descending sub frame and at least one sub-frame of uplink, and at most 1 special subframe.On 7 kinds performed in FS2 Descending sub frame configuration mode is as shown in table 1.

Table 1

When user plane (User Plane, abbreviation U plane) time delay of LTE system is handled by the base station Between, frame time alignment, Transmission Time Interval (TTI, the Transmission Time Interval) time Constituted with the part of terminal processes time four, wherein frame time alignment is that business is resulted in the business of reaching Stand-by period between sub-frame transmission chance of eating dishes without rice or wine.

By taking LTE-FDD downlink transfers as an example, because each subframe of FDD system has downlink transfer machine Meeting, frame time alignment average out to 0.5ms.Base station processing time is 1ms, up side in down direction To when be 1.5ms；The terminal processes time is 1ms in up direction, is 1.5ms during down direction. Therefore, in the case of not considering that HARQ (hybrid automatic repeat-request) is retransmitted, LTE-FDD is descending U planes time delay=base station processing time 1ms+ frame time alignment 0.5ms+TTI time 1ms+ terminal processes Time 1.5ms, common 4ms.Similar, in the case of LTE-FDD systems do not consider that HARQ is retransmitted Up U planes delay is also 4ms.As shown in Figure 3.

For LTE-TDD systems, base station and terminal processes time and the same FDD of TTI length, such as Shown in Fig. 4 and Fig. 5.Up-downgoing used in time that frame time alignment is reached with business and system is matched somebody with somebody It is equipped with pass.By taking uplink-downlink configuration #5 as an example, if base station completes transmitting terminal processing in subframe #1, most It is early to be just transmitted to subframe #3, then the frame time alignment average out to 1.5ms for subframe of eating dishes without rice or wine is transmitted into, The frame time alignment average out to 0.5ms of remaining subframe, thus the average registration process time of downlink data be (1.5+8*0.5)/9=0.6ms.In the case of not considering that HARQ is retransmitted, table 2 and table 3 are given respectively The corresponding DL (up) of each TDD uplink-downlink configurations and UL (descending) U plane time delays are gone out Average value.

Table 2

Table 3

In the calculating of above-mentioned U planes time delay, the processing time of base station and terminal, frame time alignment are all Related to TTI length, if TTI contraction in lengths, the overall delay of U planes will shorten. On the basis of existing LTE frame structures, it may be considered that it is that 0.5ms is even smaller to shorten TTI, i.e., one The symbolic number that individual TTI length is included by a time slot in existing LTE frame structures, for example routinely It is 7 symbols during CP, is 6 symbols during extension CP；Can also further shorten TTI be less than The length of 1 time slot, such as one or several symbols.

In LTE system, existing transmission is all defined with TTI=1ms, i.e., one TTI is a subframe, and length is 1ms., will be in descending sub frame when UE needs transmission upstream data Middle detection uplink scheduling license (UpLink grant, abbreviation UL grant), uplink scheduling license makes With predetermined descending control signaling (DCI, Downlink Control Information) form (format) Transmission, for notifying terminal to carry out the resource of uplink, modulating-coding (MCS, Modulation and Coding Scheme) grade, redundancy versions, transmission power control (TPC, Transmit Power Control) the configured transmission such as order, and uplink scheduling license with its dispatch for carrying upstream data Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared CHannel) using fix Scheduling sequential relationship, i.e., the uplink scheduling sent in subframe n permit be used for dispatch in subframe n+k The PUSCH of middle transmission, wherein k are fixed as 4 for FDD, and different TDD is depended on for TDD Uplink-downlink configuration.

When the TTI length using non-1ms, data and dispatch are passed in units of subframe It is defeated, thereby increases and it is possible to which that supporting can in more flexible uplink and downlink transmission period distribution, different subframes The uplink and downlink transmission time segment length that can be included can all change with corresponding service amount, In a uplink transmission time, TTI length used in business transmission can also be according to transmission demand And dynamic change, now fixed scheduling sequential just do not apply to, data how to transmit there is no at present it is bright True scheme.

With the development and change of mobile communication business demand, multiple tissues to future mobile communication system all Define higher user plane delay performance requirement.Shortening one of main method of user's delay performance is Reduce TTI length.After TTI shortens, how to carry out data transmission also without clear and definite method.

Using a 1ms subframe as a time quantum, if terminal is always held in time quantum Specific frequency domain position in last symbol sends First ray, then to the descending biography of next time quantum In the defeated period, base station possibly can not complete the statistics and corresponding Resource Distribution and Schedule of uplink service demand Signaling is generated, therefore, more reasonably, second time quantum that base station should be after current time unit Start to divide appropriate uplink and downlink transmission time length, and send uplink scheduling license, dispatch terminal Uplink, i.e., when terminal sends First ray on the symbol more rearward of a time quantum, most B under ascending resource distribution, this kind of mode can be obtained in second after the time quantum time quantum soon Equal to 2；The uplink scheduling time delay of which is relative to become big, but can reduce as far as possible in a time quantum Switching between uplink and downlink, for example, only need to the switching of a downstream-to-upstream, as shown in Figure 9.

In examples detailed above, according to send First ray terminal number how much, base station can flexibly control next The division of uplink and downlink transfer resource in individual time quantum, such as when uplink service is more, distribute more Symbol be used for uplink, it is appropriate to reduce the symbolic number that uplink takes when uplink service is less, more Many symbols give downlink transfer；In addition, only terminal needs just to send the first sequential during transmission upstream data, In the 3rd time quantum for example in figs. 8 and 9, do not send First ray, illustrate terminal not on Row data need transmission；If base station do not detect that any terminal sends in the 3rd time quantum the One sequence, then in next time quantum, can be distributed on downlink transfer, so as to reach by all symbols To flexible downstream transmission resource allocation.

To sum up, the embodiment of the present invention provides a kind of First ray by being sent in specific time-frequency domain position, The method for realizing ascending resource request is more simple and flexible for when Transmission Time Interval shortens, supporting Uplink, improve efficiency of transmission；And interference information can be provided to adjacent area simultaneously, for subsequent interference Eliminate.
