When the high position of MS is 1, then modulation system is 64QAM; When the high position of MS is 0, low level is 0, and then modulation system is QPSK; When the high position of MS is 0, low level is 1, and then modulation system is 16QAM.

When a MS high position is 1, low level is 0, and then former signaling information is identical with the signaling information of correction;

Embodiment 1:

When signaling information is the HARQ process ID, then use table 1:

x MsValue	MSB (x Ms, 1)	LSB (x Ms, 2)	Modulation system	Signaling information
					0	0	0	QPSK	The HARQ process ID number is the value between 0 to 7.
1	0	1	16QAM	The HARQ process ID number is the value between 0 to 7.
					2	1	0	64QAM	The HARQ process ID number is the value between 0 to 7.
3	1	1	64QAM	The HARQ process ID number is the value between 8 to 15.

Table 1

Here, MSB is a highest order, and LSB is a lowest order.

The implication of table 1 is to work as x _Ms, 1, x _Ms, 2 when using " 10 ", and the expression modulation system is the 64QAM modulation, and the HARQ process of current transmission is one in the 0th to the 7th process of HARQ.Work as x _Ms, 1, x _Ms, 2 when using " 11 ", and the expression modulation system is the 64QAM modulation, and the HARQ process of current transmission is one in the 8th to the 15th process of HARQ.Remaining 2 kinds of codings " 00 " and " 01 " are to be used for the QPSK and the 16QAM modulation system of compatible original HSDPA system.

Because the HARQ process ID number is 3 bits, so in the prior art, HARQ can only be 0～7 process.And in the embodiment of the invention, when modulation system is 64QAM, can use the auxiliary expression of LSB HARQ process ID number.That is: be 0 to represent 0～7 process of HARQ with LSB, the signaling information of correction is identical with former signaling information; And be 1 to represent 8～15 processes of HARQ with LSB, because the HARQ process ID number is 3 bits, then the HARQ process ID of Xiu Zhenging number number subtracts 8 for former HARQ process ID, can use 3 bits to represent, like this, just can represent 0～15 process, expand one times than prior art.

In reduction time,, when a MS high position is 1, low level is 1, and expression HARQ process ID number has passed through correction, and former HARQ process ID number number adds 8 for the HARQ process ID revised, other situation, and the HARQ process ID of former HARQ process ID number and correction is number identical, remains unchanged.

Embodiment 2,

When signaling information is transport block size information, then use table 2:

x MsValue	MSB (x Ms, 1)	LSB (x Ms, 2)	Modulation system	Signaling information
					0	0	0	QPSK	TBS is the value between 0 to 63.
1	0	1	16QAM	TBS is the value between 0 to 63.
					2	1	0	64QAM	TBS is the value between 0 to 63.
3	1	1	64QAM	TBS is the value between 64 to 127.

Table 2

Here, MSB is a highest order, and LSB is a lowest order.TBS is transport block size information (Transmission Block Size), and this information transfers out at the second portion of HS-SCCH.

The implication of table 2 is to work as x _Ms, 1, x _Ms, during 2 uses " 10 ", the expression modulation system is the 64QAM modulation, and TBS is the value between 0 to 63.Work as x _Ms, 1, x _Ms, during 2 uses " 11 ", the expression modulation system is the 64QAM modulation, and TBS is the value between 64 to 127.Remaining 2 kinds of codings " 00 " and " 01 " are to be used for the TBS value of compatible original HSDPA system.

Because transport block size information is 6 bits, so in the prior art, can only be the value between the size 0～63 of transmission block.And in embodiments of the present invention, when modulation system is 64QAM, can use the auxiliary expression of LSB transport block size information, that is: be 0 to represent that the value of transmission block size is 0～63 with LSB, the signaling information of correction is identical with former signaling information; And be 1 to represent that the value of transmission block size is 64～127 with LSB, because transport block size information is 6 bits, so the transport block size information of revising is former transport block size minus 64, can use 6 bits to represent, like this, the value that just can represent the transmission block size is 0～127, has expanded one times than prior art.

In reduction time,, when a MS high position is 1, low level is 1, and the expression transport block size information has been passed through correction, and former transmission block size adds 64 for the transmission block size of revising; Other situation, former transport block size information is identical with the transport block size information of correction, remains unchanged.

So the present invention can provide higher systematic function on the basis of complete compatible existing system.

More than describe operation principle of the present invention in detail, but the example of this visualization of just lifting for the ease of understanding should not be considered to be limitation of the scope of the invention.Equally, according to the description of technical scheme of the present invention and preferred embodiment thereof, can make various possible being equal to and change or replacement, and all these changes or replacement all should belong to the protection range of claim of the present invention.

In the described step (1), when described modulation system was 64QAM, the high position of MS was 1; When modulation system was QPSK, the high position of MS was 0, and low level is 0; When modulation system was 16QAM, the high position of MS was 0, and low level is 1;

In the described step (4), when the high position of MS is 1, then modulation system is 64QAM; When the high position of MS is 0, low level is 0, and then modulation system is QPSK; When the high position of MS is 0, low level is 1, and then modulation system is 16QAM.

7. communication means according to claim 6 is characterized in that, described signaling information is HARQ process ID number or transport block size information,

In the described step (1),

When modulation system was 64QAM, if HARQ process ID number is between 0 to 63 for the 0th to the 7th process or the transmission block size of HARQ, then the low level of MS was 0, and the signaling information of correction is identical with former signaling information; If signaling information is that the 8th to the 15th process or the transmission block size of HARQ is between 64 to 127, then the low level of MS is 1, and the HARQ process ID of correction number number subtracts 8 for former HARQ process ID, and the transport block size information of correction is former transport block size minus 64;

When modulation intelligence was 16QAM or QPSK, the signaling information of correction was identical with former signaling information;

In the described step (4), when a MS high position is 1, low level is 0, and then former signaling information is identical with the signaling information of correction;

When a MS high position is 1, low level is 1, and then former HARQ process ID number number adds 8 for the HARQ process ID revised, and former transmission block size adds 64 for the transmission block size of revising;

When the high position of MS is 0, then former signaling information is identical with the signaling information of correction.

8. communication means according to claim 5 is characterized in that,

In the described step (2), with the channelization code set information multiplexing of modulation scheme information and MAC-hs layer together, be mapped to first time slot of HS-SCCH; The HARQ process ID of the transmission block size of the redundancy version parameters of MAC-hs floor, correction, correction number, new data indication information is together multiplexing, be mapped to second time slot and the 3rd time slot of HS-SCCH;

In the described step (3), demultiplexing goes out HARQ process ID number, the new data indication information of transmission block size, the correction of modulation scheme, channelization code set information and redundancy version parameters, correction.
