Description

The indication of modulation mode of high speed down sharing physical channel, determine method and apparatus

Technical field

The present invention relates to the indication of channel modulation mode and determine technology, relate to definite method and apparatus of the indicating means of high speed down sharing physical channel (HS-PDSCH, High Speed Physical Downlink Shared Channel) modulation system and device, HS-PDSCH modulation system or rather.

Background technology

Along with market growing to the high-speed data service demand, 3GPP has introduced important enhancement techniques in Release5 and Release6 Version Spec: high speed downlink packet inserts (HSDPA, High SpeedDownlink Packet Access) technology to contend with other wireless access technology.The HSDPA technology is a kind of improvement technology of introducing for the downlink business speed that improves system in the 3G system.HSDPA is the set of some wireless enhanced technology, on its purpose is to satisfy/the asymmetric demand of downstream data traffic, the user's peak rate and the cell data throughput of down link be can under the situation that does not change existing 3G network structure, promote, thereby the performance and the capacity of grid improved greatly.Its basic physical layer key technology mainly comprises: adaptive modulation and coding technology (AMC, Adaptive Modulation and Coding), hybrid automatic repeat request technology (HARQ, Hybrid Automatic Repeat reQuest) and high order modulation technology etc.For high order modulation, two kinds of optional modulation systems in HSDPA, have been adopted, i.e. QPSK and 16QAM.At present, the progress of TD-SCDMA aspect HSDPA is also very fast.

Descending shared control signal channel (the HS-SCCH that in TDD HSDPA, increases newly, Shared ControlChannel for HS-DSCH) is responsible for carrying to high speed descending sharing channel (HS-DSCH, High SpeedDownlink Shared Channel) necessary control information of channel-decoding and schedule information, a HS-SCCH takies 2 descending spreading factor (SF, Spread Frequency) is 16 code channel, and all take time slot (time slot format) #5 and #0, adopt Quadrature Phase Shift Keying modulation (QPSK).The information that NodeB may transmit a plurality of HS-SCCH is given not terminal on the same group, if HS-SCCH is not determined, terminal will be monitored the information of maximum 4 HS-SCCH.If HS-SCCH is determined, terminal is only monitored the information of a HS-SCCH.For each HS-DSCH Transmission Time Interval (TTI), HS-SCCH carries the downlink signaling relevant with this HS-DSCH as shown in Table 1:

Table one

When downlink data need send, Node B at first sends descending scheduling and control information on HS-SCCH, to the UE indication HSDPA data are arranged on follow-up HS-PDSCH, UE receives transmission block by understanding HS-SCCH, and utilize the corresponding indicating channel (HS-SICH, Shared InformationChannel for HS-DSCH) of sharing to Node B feeding back ACK/nack message.The code channel of HS-PDSCH distributes indication signaling to use initial code (start code) and stop code (stop code), indicates the code channel of distributing to HS-PDSCH.Initial code and stop code represented by 4 bits respectively, i.e. bit x _{Ccs, 1}, x _{Ccs, 2}, x _{Ccs, 3}, x _{Ccs, 4}Expression initial code k _Start, bit x _{Ccs, 5}, x _{Ccs, 6}, x _{Ccs, 7}, x _{Ccs, 8}Expression stop code k _StopAnd work as k _Stort=15, k _StopRepresented spreading factor SF=1 at=0 o'clock, otherwise as long as k _Start＞k _Stop, promptly think wrong signaling indication.

The employed modulation system of HS-PDSCH is indicated by 1 bit, with x _{Ms, 1}Expression, this bit are 0 o'clock indication QPSK, are 1 o'clock indication 16QAM, that is:

$x_{\mathrm{ms},1}=\left\{\begin{array}{ccc}0& \mathrm{if}& \mathrm{QPSK}\\ 1& \mathrm{if}& 16\mathrm{QAM}\end{array}\right..$

Along with the development of technology, for further promoting the transmission rate of downlink data in the TDD HSDPA system, introduced the 64QAM modulation system, like this, the spendable modulation system of HS-PDSCH just has three kinds, is respectively QPSK, 16QAM and 64QAM.And the modulation system signaling only has 1 bit in the HS-SCCH signaling in the existing standard, can't indicate three kinds of modulation systems.In order to support the indication of downlink 64 QAM modulation system, must make amendment or redesign the corresponding control signaling of HS-SCCH.

Fig. 1 is the indicating means flow chart of HS-PDSCH modulation system of the present invention, and as shown in Figure 1, the indicating means of HS-PDSCH modulation system of the present invention may further comprise the steps:

Step 101: the HS-PDSCH code channel distributes the signaling of indication among the expansion HS-SCCH.That is, the assignment scope that the HS-PDSCH code channel distributes the indication signaling sign indicating number among the expansion HS-SCCH allows code channel to distribute the initial code k of indication _StartGreater than stop code k _StopOnly have at channel modulation mode under the situation of QPSK and two kinds of modulation systems of 16QAM, code channel distributes the initial code k of indication signaling _StartGreater than stop code k _StopThe time, belong to false command.The present invention distributes indication signaling to expand to the HS-PDSCH code channel, allows k _StartGreater than stop code k _Stop, and be used to refer to the situation that HS-PDSCH adopts the 64QAM modulation system.

Step 102: the modulation system of using the HS-PDSCH code channel to distribute the signaling of indication to indicate HS-PDSCH with the modulation system signaling.Below by example, describing the present invention in detail is how to utilize code channel to distribute the initial code k of indication signaling _Start, stop code k _StopAnd modulation system signaling code x _{Ms, 1}Indicate the modulation system of HS-PDSCH.

When modulation system is QPSK, k _Start, k _StopAnd x _{Ms, 1}Value is as follows with the indication rule:

x _{Ms, 1}=0, and k _Start≤ k _StopThe time, the spreading factor of code channel is 16, k _StartThe indication initial code Taoist monastic name that HS-PDSCH distributed, k _StopThe indication stop code Taoist monastic name that HS-PDSCH distributed; x _{Ms, 1}=0, k _Start=15 and k _Stop=0 o'clock, the modulation system that indication HS-PDSCH adopts was QPSK, and the spreading factor of code channel is 1.

When modulation system is 16QAM, k _Start, k _StopAnd x _{Ms, 1}Value is as follows with the indication rule:

x _{Ms, 1}=1, k _Start≤ k _StopThe time, the modulation system that indication HS-PDSCH adopts is 16QAM, the spreading factor of code channel is 16, k _StartThe indication initial code Taoist monastic name that HS-PDSCH distributed, k _StopThe indication stop code Taoist monastic name that HS-PDSCH distributed; x _{Ms, 1}=1, k _Start=15 and k _Stop=0 o'clock, the modulation system that indication HS-PDSCH adopts was 16QAM, and the spreading factor of code channel is 1.

That is to say that under QPSK, 16QAM indicating mode, the indication rule in the present invention and the existing TDD HSDPA system is identical, just, can not only pass through modulation system signaling code x _{Ms, 1}Indicated the modulation system of HS-PDSCH, necessary and k _Start, k _StopIt is common definite to come together.This does not increase the indication complexity under these two kinds of modulation systems.

The modulation system that HS-PDSCH adopts is 64QAM, k _Start, k _StopAnd x _{Ms, 1}Value is as follows with the indication rule:

The spreading factor that HS-PDSCH distributed is that 16 code channel is one when above, x _{Ms, 1}=0, k _StopThe indication initial code Taoist monastic name that HS-PDSCH distributed, k _StartThe indication stop code Taoist monastic name that HS-PDSCH distributed; The spreading factor that HS-PDSCH distributed is 16 a code channel when being 16, x _{Ms, 1}=1, in 0 to 15 k _Stop, k _StartDetermine unique value respectively, special indication is as k _Stop=15, k _Start=2.When the code channel that HS-PDSCH distributed is under the SF=16 situation whole 16,, use k as the situation of the SF=1 under front QPSK, the 16QAM modulation _Stop, k _StartSpecific value indicate specially, only however with aforesaid k _Stop=15, k _Start=0 repeats to get final product.

For HS-PDSCH distributes the spreading factor of code channel is 16 and during for the solid size road, x _{Ms, 1}=1, for 0 number road, in 0 to 15 k _Stop, k _StartDetermine unique value respectively, special indication is as k _Stop=2, k _Start=0; For 1 to 15 number road, k _Start=k _Stop+ 1, k _StartThe indication sign indicating number Taoist monastic name that HS-PDSCH distributed; Perhaps, for 15 number roads, in 0 to 15 k _Stop, k _StartDetermine unique value respectively, special indication is as k _Stop=3, k _Start=0; For 0 to 14 number road, k _Start=k _Stop+ 1, k _StopThe indication sign indicating number Taoist monastic name that HS-PDSCH distributed.Need to prove why select k _Start=k _Stop+ 1 situation, for simplified design is considered, because, at k _Start, k _StopDiffering is under 1 the situation, to have only 0 number road or 15 number roads not to represent by above-mentioned indication rule, for 0 number road or 15 number roads, selects specific k for use _Start, k _StopValue is represented to get final product, and so can the increase system determine the complexity of HS-PDSCH modulation system.

For HS-PDSCH distributes the spreading factor of code channel is 1 o'clock, x _{Ms, 1}=1, in 0 to 15 k _Stop, k _StartDetermine unique value respectively, special indication is as k _Stop=15, k _Start=1.

Just, when determining SF=1 when three kinds of modulation system indications and aforementioned other special indication situation, the x that selects for use _{Ms, 1}, k _Stop=15, k _Start=1 has any different and unique getting final product.

Adopting modulation system for HS-PDSCH is the situation of 64QAM, because original system does not use this modulation system, needn't consider factors such as amalgamation, therefore, and aforementioned k _Start, k _StopAnd x _{Ms, 1}Value is indicated in the description of rule, with x with scheduling _{Ms, 1}Value still can realize to modulation system being the indication of 64QAM, specifically referring to table three by 0 being changed to 1, being changed to 0 by 1.

About the modulation system indication and the distribution of code channel, can be referring to the example in table two, the table three, with understanding more directly perceived technical scheme of the present invention.

Table two

Table three

Table two and table three maximum different promptly are 64QAM when adjusting mode, modulation system sign indicating number x _{Ms, 1}The value difference.

Because the present invention does not change the length of each signaling of HS-SCCH in the existing standard, therefore can not cause the expense of resource, and the indicating means of HS-PDSCH modulation system in the existing standard is merged in the present invention as much as possible, is not very big to the change of existing protocol.The present invention by to the appropriate design of HS-SCCH signaling the method for indicating three kinds of descending modulation systems and code channel to distribute, the complexity of coming minimization system to determine by simple mapping relations for the adjustment mode.
