Embodiment
When there is azygous carrier frequency in the uplink and downlink link, be that the carrier frequency (being called for short the uplink and downlink carrier frequency) of uplink and downlink link is when number is not identical, one embodiment of the invention provides information transferring method in a kind of multicarrier system, mainly comprise: set up the HS-DPCCH channel in up link, wherein, the HS-DPCCH channel number of foundation is identical with the number N of descending carrier frequency, the number M＜N of uplink carrier frequencies, M, N is non-zero positive integer; With the HS-DPCCH channel allocation of N up link to uplink carrier frequencies; If have on the uplink carrier frequencies greater than a HS-DPCCH channel, the information on a plurality of HS-DPCCH channels on this carrier frequency is distinguished; Information on N the HS-DPCCH channel is transmitted.
The carrier frequency number of uplink and downlink link is not identical can to comprise two kinds of situations:
1. uplink carrier frequencies number M is more than or equal to the carrier frequency number N of down link, this moment can with uplink carrier frequencies corresponding to descending carrier frequency on the direct information on the transmission HS-DPCCH channel, its transmission means and prior art are basic identical, herein in detail introduction;
2. uplink carrier frequencies number M gives on each uplink carrier frequencies and distributes at least a HS-DPCCH channel less than descending carrier frequency number N this moment, transmits after distinguishing for the informational needs on the different HS-DPCCH channels on the same carrier frequency.
Wherein, can be by using scrambler carry out scrambling, using different channel code, perhaps by methods such as the I/Q road are multiplexing, the information on a plurality of HS-DPCCH channels on the same uplink carrier frequencies is distinguished.
Another embodiment of the present invention provides information transferring method in a kind of multicarrier system, and the number of supposing uplink carrier frequencies is M, and descending carrier frequency number is N, M＜N, and M, N is non-zero positive integer, and as shown in Figure 1, the method can comprise:
S101 sets up the HS-DPCCH channel in up link.
When down link when N carrier frequency set up HSDPA, can also set up N HS-DPCCH channel in up link, required information of carrier frequency of each HS-DPCCH channel feedback is such as PCI, CQI and ACK/NACK indication.Wherein, the coding of feedback information and transmission means and single-frequency communication system of the prior art are basic identical.
S102, with the HS-DPCCH channel allocation of the up link set up to uplink carrier frequencies.
Such as, for the N that sets up on this uplink carrier frequencies HS-DPCCH channel, can be assigned on M the uplink carrier frequencies.Because N＞M, must have greater than 1 HS-DPCCH channel on certain or some uplink carrier frequencies.
S103 uses different channel code to distinguish to the information on the different HS-DPCCH channels on the same uplink carrier frequencies.
By giving the HS-DPCCH channel allocation channel code of up link, can be used for distinguishing the information on the different HS-DPCCH channels.
In order more clearly to be described, M uplink carrier frequencies is numbered 1,2 ... M.
Concerning each carrier frequency, the channel code that its article one HS-DPCCH uses is the same with single-carrier system, can operate by existing protocol.
But, as previously mentioned, when N＞M, have greater than 1 HS-DPCCH channel on certain or some uplink carrier frequencies, for the HS-DPCCH channel on these carrier frequency, can in conjunction with each carrier frequency channel code operating position, distribute different channel code.
For example, uplink carrier frequencies number M=2, in the situation of descending carrier frequency number N=5, wherein a kind of possible channel allocation situation is: set up 5 HS-DPCCH channel 1-5 on the up link, HS-DPCCH channel 1,3,5 is assigned on the uplink carrier frequencies 1, HS-DPCCH channel 2,4 is assigned on the uplink carrier frequencies 2.
Suppose that HS-DPCCH channel 1 is according to the regulation of agreement, used channel code C1, HS-DPCCH channel 2 also uses channel code C2 transmission information on uplink carrier frequencies 2 according to the regulation of agreement, two other HS-DPCCH channel 3 on the uplink carrier frequencies 1,5 can use channel code idle on this carrier frequency, similarly, another HS-DPCCH channel 4 on the uplink carrier frequencies 2 can use channel code idle on this carrier frequency.
Need to prove that for the HS-DPCCH channel on the different carrier frequency, the channel code that they use might be identical, also might be different.
S104, the information on the transmission HS-DPCCH channel.
Can after the channel code that determines each HS-DPCCH channel, will transmit behind the information spread spectrum on N the HS-DPCCH channel.
The method that above-described embodiment provides, for the asymmetric situation of uplink and downlink carrier frequency, can be under the prerequisite of not revising coding and transformat, for a plurality of HS-DPCCH channels on the same carrier frequency, can be by different channel code, effectively distinguish from the information of different HS-DPCCH channels and transmit, such as by HS-DPCCH channel feedback PCI, CQI and ACK/NACK indication information.
Another embodiment of the present invention provides information transferring method in a kind of multicarrier system, and the number of supposing uplink carrier frequencies is M, and descending carrier frequency number is N, M＜N, and M, N is non-zero positive integer, and as shown in Figure 2, the method can comprise:
S201 sets up the HS-DPCCH channel in up link.
S202, with the HS-DPCCH channel allocation of the up link set up to uplink carrier frequencies.
Wherein, S201, the implementation of S202 and S101, S102 is basic identical, repeats no more herein.
S203 crosses to the information exchange on the different HS-DPCCH channels on the same uplink carrier frequencies that the I/Q road is multiplexing to be distinguished.
That is to say, on same carrier frequency, by the information on the different HS-DPCCH channels of the multiplexing differentiation use in I/Q road same channel code.
In order to understand better this scheme, below in conjunction with the application scenarios of HSDPA, to being described in detail by the multiplexing method in I/Q road.
M uplink carrier frequencies is numbered 1,2 ... M, N HS-DPCCH channel number is 1,2 ... N.
For a plurality of HS-DPCCH channels on a uplink carrier frequencies, in the situation that the channel code on each branch road does not clash, per two HS-DPCCH channels can use identical channel code, but can be distributed in respectively on two branch roads of I road and Q, thereby the information on a plurality of HS-DPCCH channels is distinguished; Can use different channel code to distinguish for a plurality of HS-DPCCH channels on the same branch road of same uplink carrier frequencies.For example, suppose to have distributed on the uplink carrier frequencies 3 HS-DPCCH channels, first HS-DPCCH channel has used channel code C1 to be distributed in the I road of this carrier frequency, if C1 does not conflict with the channel code of other physical channels on the Q road, then second HS-DPCCH channel on this uplink carrier frequencies can use channel code C1 and be distributed on the Q road; If the channel code of other physical channels is conflicted on C1 and the Q road, then select in addition the channel code of a free time, and the 3rd HS-DPCCH channel on this uplink carrier frequencies can use the channel code of a free time, is dispensed on I road or the Q road.
Further, information exchange on the different HS-DPCCH channels on the same uplink carrier frequencies is crossed the I/Q road when multiplexing, also can be at first according to the principle of I/Q gross power balance, select the information of the HS-DPCCH channel that distributes on this uplink carrier frequencies at which branch road to transmit, for example, there have been a plurality of other physical channels in the I road of uplink carrier frequencies 1, and physical channel is less on the Q road, the power on I road is higher so, at this moment, all information that are assigned on the HS-DPCCH channel on this carrier frequency can use different channel code all to transmit on the Q road, if and the power itself on two branch roads is balance, two HS-DPCCH channels can be carried out multiplexingly, if no conflict occurred for branch road upper signal channel code, the HS-DPCCH channel on two branch roads can use identical channel code.
Table 1 is with N=2, and the scene of M=1 is selection and the multiplexed situation that example illustrates various situation lower channel codes, wherein N
Max-dpdchThe number that represents maximum Dedicated Physical Data Channel, C
Ch, SF, kThe numbering of expression channel code.
The channel code of table 1HS-DPCCH channel is selected and multiplexed situation
S204 transmits the information on N the HS-DPCCH channel.
Can after the multiplexed situation that is determining each HS-DPCCH channel and channel code, will transmit behind the information spread spectrum on N the HS-DPCCH channel;
In addition, be understandable that, to the information on the uplink carrier frequencies that only has a HS-DPCCH channel, owing to do not need to distinguish, also can transmit first the information on the HS-DPCCH channel on these uplink carrier frequencies.
The method that above-described embodiment provides, for the asymmetric situation of uplink and downlink carrier frequency, can be under the prerequisite of not revising coding and transformat, for a plurality of HS-DPCCH channels on the same carrier frequency, can be multiplexing by the I/Q road, effectively distinguish from the information of different HS-DPCCH channels and transmit, such as by HS-DPCCH channel feedback PCI, CQI and ACK/NACK indication information.
Another embodiment of the present invention also provides information transferring method in a kind of multicarrier system, and as shown in Figure 3, the method can comprise:

S303 uses the scrambler scrambling to distinguish to the information on a plurality of HS-DPCCH channels on the same uplink carrier frequencies.
In order to distinguish the information that comes from the different HS-DPCCH channels, can dispose at least one scrambler to the user, information on the HS-DPCCH channel is transmitted according to the prior art spread spectrum and after using the scrambler scrambling of disposing, wherein, each user configured scrambler is not identical, is used for distinguishing the data from different user.
Dispose at least one scrambler to the user, the information on the HS-DPCCH channel can be had multiple different situation according to the prior art spread spectrum and after using the scrambler scrambling of disposing, for example:
Suppose to have on the up link M carrier frequency, N carrier frequency arranged on the down link, N＞M wherein,
1. dispose two scramblers for each user, to there being M HS-DPCCH channel of corresponding uplink carrier frequencies, their information can transmitted by existing mode spread spectrum and after with 1 scrambling of the first scrambler on the uplink carrier frequencies of correspondence.To unnecessary N-M HS-DPCCH channel, their information can be with 2 scramblings of the second scrambler, as long as the scrambler of a plurality of HS-DPCCH channels on the same carrier is different.For example a kind of available carrier frequency selection mode can adopt following principle during M=2:
A. the information on M+1 HS-DPCCH channel is in uplink carrier frequencies 1 transmission;
B. the information on M+2 HS-DPCCH channel is in uplink carrier frequencies 2 transmission;
C. the information on M+3 HS-DPCCH channel is in uplink carrier frequencies 1 transmission;
D. the rest may be inferred.
At this moment, may occur having greater than 1 HS-DPCCH channel on certain or some uplink carrier frequencies and use identical scrambler transmission information, can distinguish these channels with different spreading codes.The selection principle of spreading code is that different HS-DPCCH channels is used different spreading codes.For example to up a carrier frequency (f1) arranged, the descending scene that 3 carrier frequency (f1/f2/f3) are arranged, with can use scrambler 1 scrambling behind the information spread spectrum on HS-DPCCH channel corresponding to f1 after transmit, all the other two HS-DPCCH channels all use scrambler 2 scramblings to transmit at f1, but in order to distinguish this two channels, can be with different channel code spread spectrums.
2. dispose N-M+1 scrambler for each user, to there being M HS-DPCCH channel of corresponding uplink carrier frequencies, their information can transmitted by existing mode spread spectrum and after with scrambler 1 scrambling on the uplink carrier frequencies of correspondence.To unnecessary N-M HS-DPCCH channel, the information on each HS-DPCCH channel is transmitted after can using different scrambler scramblings.
Need to prove, giving user configured scrambler not only can be 2 or N-M+1, also can be other scheme, for example, can make 2 and N-M+1 between a number, in conjunction with the use of spreading code, need only the information that can guarantee to distinguish on the different HS-DPCCH channels.
S304, the information on the transmission HS-DPCCH channel.
After to the scrambler scrambling of the information on the HS-DPCCH channel according to prior art spread spectrum and use configuration, the communication after the scrambling is gone out.
The method that above-described embodiment provides, for the asymmetric situation of uplink and downlink carrier frequency, can be under the prerequisite of not revising coding and transformat, for a plurality of HS-DPCCH channels on the same carrier frequency, by adopting the scrambler scrambling, effectively distinguish from the information of different HS-DPCCH channels and transmit, such as by HS-DPCCH channel feedback PCI, CQI and ACK/NACK indication information.
In above-mentioned all embodiments of the method, for the N on the up link HS-DPCCH channel allocation arrived M uplink carrier frequencies, a HS-DPCCH channel can be distributed at least on each carrier frequency, following scheme can be adopted:
1.N be the integral multiple of M, to M uplink carrier frequencies, that is to say has N/M HS-DPCCH channel on each uplink carrier frequencies with N HS-DPCCH channel mean allocation;
2.N be not the integral multiple of M, if N=k * M+i, k is the integer greater than 1, i is greater than 1 and less than the integer of M, then distribute at least k HS-DPCCH channel on each uplink carrier frequencies, unnecessary i HS-DPCCH channel allocation to any i uplink carrier frequencies or with unnecessary i HS-DPCCH channel allocation to any one or several carrier frequency.
Need to illustrate, when N HS-DPCCH channel allocation is to M the uplink carrier frequencies, also can be according to the actual conditions of each carrier frequency (for example, the physical channel number that distributes at present) distributes, a plurality of HS-DPCCH channels may be distributed on some carrier frequency, the HS-DPCCH channel may be not can on some carrier frequency distributed.
