Specific implementation mode
The principle and spirit of the invention are described below with reference to several illustrative embodiments.It should be appreciated that providing this
A little embodiments are used for the purpose of making those skilled in the art can better understand that realizing the present invention in turn, and be not with any
Mode limits the scope of the invention.
Fig. 1 shows the frame structure in wireless communication system (for example, TD-SCDMA).In a wireless communication system, such as
In existing TD-SCDMA communication systems, physical layer frame structure is as shown in Figure 1.One radio frames for example can be 10ms,
Such as may include two subframes, each subframe for example can be 5ms.One subframe may include multiple time slots, such as can be with
Including TS0, TS1 (the 1st time slot) ..., TS6 (the 6th time slot).By taking mobile device as an example, usual TS4 to TS6, which is assigned, to be used
In HS-PDSCH (for example, receiving data from base station), wherein TS3 is generally allocated for control signal and does not carry data.Separately
Outside, TS1 or TS2 is allocated for HS-SICH (for example, notifying whether received correctly in its corresponding HS-PDSCH to base station
Data).Therefore, if TS0 can be allocated for HS-PDSCH to carry data, network utilization can be promoted and then carried
High network downloading rate.
Fig. 2 schematically illustrates the transmission to HS-PDSCH in TD-SCDMA agreements 25.221.As shown in Fig. 2, in TD-
When being transmitted to HS-PDSCH in SCDMA agreements 25.221, HS-PDSCH/HS-SICH transmissions adjoint and timing have as follows
Regulation:Have under UE (user equipment) and CELL-FACH (forward access channel) state under CELL-DCH (dedicated channel) state
The UE of special UE mark it is next it is effective with sent on HS-SICH the corresponding ACK/NACK of HS-DSCH (confirm response/
Negative response) need it is defined below:UE specified to one, in the HS-PDSCH (on the time) of the last one distribution and its correspondence
HS-SICH between there are one nHS-SICHThe offset of >=9 time slots.Therefore, HS-SICH transmission need always after HS-DSCH every
It is carried out in one subframe, as shown in Figure 2.If UE supports the HS-PDSCH of multiple carrier waves to send, the HS- on each carrier wave
Timing relationship between DSCH and HS-SICH is identical with single carrier case.When the HS-PDSCH of instruction includes TS0, HS-
Timing definition between PDSCH and HS-SICH is:HS-PDSCH is sent in subframe N, and HS-SICH is sent in subframe N+2.HS-
The TS0 that PDSCH includes is the TS0 of N+1 subframes.The last one HS-PDSCH HS-SICHs corresponding with its distributed in time
Between be biased to nHS-SICH>=9 time slots.
However, based on above-mentioned regulation, under certain special scenes, the HS-PDSCH that existing protocol considers is corresponding with its
The timing relationship of HS-SICH may have some conflicts.Specifically, if for configuration HS-SICH in time slot 1 (TS1) or
Person is about 1: 5 time slot ratio (that is, an ascending time slot, five descending time slots) configuration, and HS-PDSCH supports TS0 enhancings,
Its clear corresponding HS-SICH then will be unable to according to above-mentioned agreement and specifically send subframe, and cause there are following twos may
Mode:
(1) HS-SICH selections are sent in N+2 subframes, but will be unsatisfactory for n at this timeHS-SICHThe limitation of >=9 time slots.With
And
(2) if by n is metHS-SICH>=9 time slots, HS-SICH need to select to send in N+3 subframes.
It should be understood that being directed to aforesaid way (1), HS-SICH configurations are considered in time slot 1, from HS-DSCH to the N+ of N+1 subframes
Interval between the HS-SICH of 2 subframe TS1 will only have 8 time slots (TS0 of TS0 to the TS6 and N+2 subframes of N+1 subframes),
No longer meet nHS-SICHThe limitation of >=9 time slots.
Since there are the possible realization methods of above-mentioned two kind, under conditions of supporting TS0 enhancings, when configuration HS-SICH exists
When time slot 1 or about 1: 5 time slot are than configuration, if different terminal devices and network is realized in different ways,
Existing network can then be realized and be had an impact.Specifically, following situations may be will produce:
(a) for network take different modes configuration send HS-SICH subframes terminal, since network can not know,
The HS-SICH that network side receives will generate dislocation;
(b) for network take same way configuration send HS-SICH subframes terminal, if there is its in (a)
His terminal, then HS-SICH both may will produce collision so that and network takes the terminal transmission that same way configures
HS-SICH may can not be properly received by network (and allows network for the different realization method of terminal for supporting TS0 enhancings
Carry out flexible handover configurations to go to receive HS-SICH, can bring larger complexity to base station for upper from realizing, be also required to simultaneously
Additional agreement space interface signaling supports the terminal by this message informing to base station);
(c) for the terminal for not supporting TS0 to enhance, if there is the other-end in (a), the HS-SICH of the two also has
There may be collisions so that does not support the HS-SICH that the terminal that TS0 enhances is sent that may also can not be properly received by network.
Fig. 3 may go out when schematically illustrating the secondary carrier of the same network of service access of three kinds of different types of terminals
3 kinds of existing conflict situations.As shown in figure 3, the same network of the service access for specifically giving three kinds of different types of terminals
Secondary carrier when 3 kinds of conflict situations as described above for being likely to occur.The concrete configuration of network and terminal is:Network simultaneously can
Support TS0 enhances and the terminal device of non-TS0 enhancings, and to supporting the terminal unification that TS0 enhances according to N+2 subframes in TS1
Gap sends HS-SICH;Terminal one, terminal two support TS0 enhancings, but the subframe transmission HS-SICH that each self-supporting is different, terminal three
TS0 is not supported to enhance, respectively to the adjoint and timing relationship of HS-DSCH/HS-SICH transmissions when Fig. 3 gives specific
Order relation.
The following conflict situations that we are likely to occur according to the relationship description of above-mentioned (a), (b), (c):
If (a) network configurating terminal two receives the HS-DSCH for including TS0 in subframe T, network side will be considered that terminal two exists
T+2 subframes send corresponding HS-SICH, and actually terminal two is but just sent in T+3, then network and terminal-pair HS-SICH and HS-
The understanding of the correspondence of DSCH will generate dislocation.If link-quality is bad, i.e. HS-SICH sends NACK, then needs network
When stressing to pass data, since corresponding HS-DSCH/HS-SICH relationships misplace, re-transmission will be unable to carry out, to greatly reduce
The message transmission rate of link;
If (b) network configurating terminal three receives the HS-DSCH for including TS0 in T+1 subframes, configurating terminal two connects in subframe T
It receives, since HS-SICH is high-speed shared information channel, it is possible to which network is in T+1 sub-frame configuration terminals three and T sub-frame configurations are whole
Same HS-SCCH/HS-SICH pair has been selected in HS-SCCH (High-Speed Shared Control Channel) subset when holding two, then terminal two exists
The HS-SICH that the HS-SICH that T+3 subframes are sent will be sent with terminal three in T+2 subframes generates collision, very so as to cause network
The HS-SICH of the transmission of terminal two can not extremely be received;
If (c) network configurating terminal one receives the HS-DSCH not comprising TS0 in T+1 subframes, configurating terminal two is in subframe T
It receives, in same (b), if network has selected HS-SCCH at T+1 sub-frame configurations terminal a period of time and T sub-frame configuration terminals two
Same HS-SCCH/HS-SICH pairs is concentrated, then the HS-SICH that terminal one is sent in T+3 subframes will be with terminal three in T+2
The HS-SICH that frame is sent generates collision, causes network that can not even receive the SICH of the transmission of terminal one.
Above-mentioned three kinds of situations are summarized, for taking different modes configuration to send the terminal of HS-SICH subframes with network, are sent out
The HS-SICH sent will will produce dislocation in network side reception, meanwhile, what which may send other types terminal
HS-SICH also generates interference, and HS-SICH receptions occur misplacing or interfering greatly reducing HS-DSCH transmission rates.Production
The root of the raw above problem it is also possible that due to the HS-DSCH/HS-SICH channels of network support are adjoint and timing relationship and certain
A little terminal (such as above-mentioned terminal two) it is inconsistent caused by.And this indefinite definition just because of existing protocol to this,
This potential conflict is just resulted in occur.Therefore, to the adjoint of the HS-PDSCH/HS-SICH transmissions comprising TS0 and calmly
When make specific regulation, by existing protocol about this respect description carry out supplement and it is perfect, this for support TS0 enhancing
The realization of HS-PDSCH high-speed data services transmission is very urgent and necessary.The embodiments of the present invention are exactly directed to this
Kind potential conflict further explicitly defines existing protocol work and perfect.
For the adjoint and timing relationship for the HS-DSCH/HS-SICH transmissions for supporting TS0 enhancings, implementation of the invention
Mode proposes a kind of specific general mechanism, it is expected that on this basis can be into traveling one to the regulation of existing protocol this respect
What is walked is perfect.From above as can be seen that under existing protocol frame, the HS-SICH in the case where supporting TS0 enhancings sends subframe
Position can select to send in N+2 N+3 subframes.If selection N+2 modes are sent, for network side scheduling, HARQ
(hybrid automatic repeat-request) number can select smaller value, the coding redundancy degree bigger of such downlink HS-DSCH, therefore can
To obtain better receives link performance.But when being sent due to selection N+2, for certain configurations, for example HS-SICH is in time slot 1,
Can then there is a possibility that such:NHS-SICH between the HS-SICH of the TS1 of HS-DSCH to the N+2 subframes of the TS0 of N+1 subframes
By the interval of only 8 time slots.This, which can receive and decode to terminal, brings certain challenge, especially maximum transmitted block
(TBsize=14043) iterations that Turbo is decoded in the case of can be subject to certain restrictions, and this will greatly restrict high-speed downstream
The terminal receptivity of business.
Therefore, the adjoint and timing mechanism of the HS-DSCH/HS-SICH transmissions under the enhancing proposed in this paper for TS0
For (assuming that HS-PDSCH is in N sub-frame transmissions):(1) if current system supports TS0 enhancings, HS-SICH to be unified in N+3 subframes
It sends;(2) if current system does not support TS0 to enhance, HS-SICH is sent in N+2 subframes.
