Concrete application scene
As shown in Fig. 2 the network organization framework includes two base stations, respectively macro base station (Macro Bs) and micro- base
Stand (Micro Bs), and Macro Bs and Micro Bs are using new generation of wireless access technology (new RAT) base station, and are adopted
With fdd mode, the difference of two base stations is that Macro Bs use the low-frequency range less than 6G, and Micro Bs are used and are higher than 6G
High band.Terminal (UE) is located in Macro Bs overlay areas, also is located in Micro Bs overlay areas.
Based on network organization framework as shown in Figure 2, how the present invention illustrates terminal according to the successively using example
One parameter, the second parameter and/or the 3rd parameter determine the initial time of the up target-subframe of the terminal.
Using example one
Based on network organization framework as shown in Figure 2, terminal UE first it is determined that sub-frame of uplink on carry control command,
The information such as reference signal, business datum and ACK/NACK.As shown in figure 3, the subframe is the subframe on PUCH channels, subframe
On can carry one or more information in control information, business datum, reference information and HARQ feedback information, and in Fig. 3
ToffsetFor positive number and ToffsetValue it is moderate, now Macro Bs up i-th of subframe initial time be later than it is descending i-th son
The initial time of frame.
Deta bearer in descending i-th of subframe and is sent UE by Macro Bs, due to the propagation between Macro Bs and UE
Delay, at the time of UE is later than Macro Bs transmission descending i-th of subframe at the time of receiving descending i-th of subframe.UE is known
Toffset, the mode employing mode known is as follows：Known by Macro Bs system information, believed by Macro Bs control
Breath is known, predefined mode is known in advance or other modes.UE knows T after uplink synchronous process (random access procedure)a, should
TaThe time span that UE sub-frame of uplink initial time should adjust is represented, it is only related to UE and Macro Bs propagation delays, with Toffset
It is orthogonal.The initial time T of UE up i-th of subframetuiIt is i-th of descending sub frame initial time T in UEtdiBasis
Upper backward Toffset, and shift to an earlier date T again on the initial time of new determinationa, i.e. Ttui=Ttdi+Toffset-Ta, now UE's is up
Up i-th subframe of i-th of subframe initial time earlier than Macro Bs.Above-mentioned TtuiDetermination process is also applied for ToffsetIt is zero
When situation, repeat no more.
Due to ToffsetIn up i-th of the subframe determined for positive number, UE, except carrying UE is sent to the up of Macro Bs
, can also be in the ACK/NACK feedback informations of the decline carrying UE of the subframe descending i-th of subframe outside business datum, this
In example, UE is not properly received data in descending i-th of subframe, and UE feedbacks NACK give Macro Bs, Macro Bs up
I-th of subframe receives data and feedback information, determines that UE is not properly received data, Macro BS in descending i-th of subframe
Data are transmitted to UE again in descending the i-th+2 subframes.Work as ToffsetWhen being zero, UE can not feed back in up i-th of subframe
NACK(TaIt is shorter), it can only also be fed back earliest in up i+1 subframe, correspondingly, Macro Bs retransmit data and also
Postpone a descending sub frame.Therefore as the Macro BS T of existence time skew in the ranks up and downoffset, UE can be quickly to Macro
Bs feeds back NACK so that Macro Bs can retransmit data in time.
Using example two
Based on network organization framework as shown in Figure 2, as shown in figure 4, the subframe is the subframe on PUCH channels, son
One or more information in control information, business datum, reference information, HARQ feedback can be carried on frame, and in Fig. 4
Macro Bs up i-th of subframe initial time is earlier than the initial time of descending i-th of subframe, ToffsetFor negative and Toffset
It is moderate.
UE knows ToffsetMode employing mode it is as follows：Known by Macro Bs system information, by Macro Bs
Control information know, predefined mode knows in advance or other modes.UE is after uplink synchronous process (random access procedure)
Know Ta, the TaRepresent the time span that should adjust of UE sub-frame of uplink initial time, only with UE and Macro Bs propagation delay phases
Close, with ToffsetIt is orthogonal.The initial time T of UE up i-th of subframetuiIt is in UE i-th of descending sub frame starting
Carve TtdiOn the basis of in advance | Toffset|, and shift to an earlier date Ta, i.e. T again on the initial time of new determinationtui=Ttdi-|Toffset|-
Ta, now up i-th subframe of UE up i-th of subframe initial time earlier than Macro Bs.
Due to ToffsetFor negative, UE it is determined that up i-th of subframe on to Macro Bs send business datum, Macro
After Bs receives data, the ACK/NACK feedback letters of i-th of subframe up to UE are carried in the decline of descending i-th of subframe
Breath, in this example, Macro Bs are not properly received UE data in up i-th of subframe, Macro Bs feedback NACK to UE,
UE receives data and feedback information in descending i-th of subframe, determines that Macro Bs are not properly received in up i-th of subframe
Data, according to Macro Bs instruction, data are transmitted to Macro BS by UE again in up the i-th+2 subframes.Work as ToffsetFor
When zero, because ascending-descending subframes align, Macro BS can not feed back NACK in descending i-th of subframe, earliest also can only be descending i-th
+ 1 subframe is fed back, and correspondingly, UE, which retransmits data, will also postpone a descending sub frame.Therefore due to above and below Macro Bs
The T of existence time skew in the ranksoffset, Macro Bs can be quickly to UE feedbacks NACK so that UE can retransmit data in time.
Using example three
Based on network organization framework as shown in Figure 2, as shown in figure 5, Macro Bs receive the Preamble and accordingly
Ta is calculated, Stochastic accessing described here not only can be the Stochastic accessing based on competition but also can be connect at random based on non-competing
Enter.Macro Bs up j-th of subframe initial time is later than the initial time of descending j-th of subframe, T in Fig. 5offsetFor just
Number.
Now, determining the initial time of up j-th of subframe includes：The initial time T of UE up j-th of subframetuj1
J-th of descending sub frame initial time T equal to UEtdj；Or, UE knows Toffset, know ToffsetMode employing mode it is as follows：
Known by Macro Bs system information, known by Macro Bs control information, predefined mode knows in advance or it
His mode, then the initial time T of UE up j-th of subframetuj2It is j-th of descending sub frame initial time Ttdj in UE
On the basis of fall behind Toffset, i.e. Ttuj2=Ttdj+Toffset, now UE up j-th of subframe initial time be later than Macro Bs'
Up j-th of subframe.
Using example four
Based on network organization framework as shown in Figure 2, as shown in fig. 6, UE it is determined that sub-frame of uplink on carry and connect at random
The Preamble entered, Macro Bs receive the Preamble and calculate T accordinglya, Stochastic accessing described here both can be
Stochastic accessing based on competition can be based on non-competing Stochastic accessing again.Macro Bs up j-th of subframe rises in Fig. 6
The moment begin earlier than the initial time of descending j-th of subframe, ToffsetFor negative.
Now, determining the initial time of up j-th of subframe includes：The initial time T of UE up j-th of subframetuj1
J-th of descending sub frame initial time T equal to UEtdj；Or UE knows Toffset, know ToffsetMode employing mode it is as follows：It is logical
The system information for crossing Macro BS is known, known by Macro Bs control information, predefined mode is known in advance or other
Mode, then the initial time T of UE up j-th of subframetuj2It is j-th of descending sub frame initial time T in UEtdjBase
On plinth in advance | Toffset|, i.e. Ttuj2=Ttdj-|Toffset|, now UE up j-th of subframe initial time is later than Macro Bs
Up j-th of subframe.
It should be noted that the present invention applies network organization framework of the example one to four based on such as Fig. 1, wherein, the end
UE is held also in Micro Bs coverages, when UE and Micro BS be in uplink synchronous or it is asynchronous when, UE determines up son
The mode of frame initial time is similar, only foregoing Marco Bs need to be substituted for into Micro Bs, repeated no more here.
Here, it is emphasized that, the Toffset between above and below Micro Bs subframes can both be transmitted by Micro Bs
To UE, UE can also be passed to by Marco Bs.
