Embodiment
In order to be more readily understood the scheme that the embodiment of the invention provides, at first MJM is further introduced.
MJM is a kind of multi-user's a digital modulation technique, and the modulation symbol of mapping is united in transmission by the data bit of a near-end user and a remote subscriber on identical downlink resource.This modulation symbol is the some constellation point in the inhomogeneous QAM modulation constellation.The inhomogeneities of planisphere can (EnergyRatio ER) adjusts, and (Quality of Service QoS), uses error sign ratio to weigh QoS herein to obtain identical service quality with the user who satisfies the decline of process different channels by power ratio.With uneven 16QAM planisphere is that example describes, and is the constellation overlapping schematic diagram of 16QAM modulation system referring to Fig. 1, and minimum spacing 2 β and bunch center distance 2 α and inhomogeneous parameter ER are specifically referring to shown in Figure 1 between constellation point.At transmitting terminal, BS is mapped to the bit of remote subscriber on the bit position that antijamming capability is strong in the inhomogeneous qam constellation point, bit b3 and b1 as decision quadrant in the 16QAM constellation among Fig. 1, and the bit of near-end user is mapped in the inhomogeneous qam constellation on the bit position a little less than the antijamming capability, as the bit b2 and the b0 of concrete constellation point in the same quadrant of decision in the 16QAM constellation among Fig. 1.
The embodiment of the invention provides a kind of transmission method and device of MJM configuration information on above-mentioned MJM analysis of technology, can adopt the MJM modulation technique to be implemented in following mobile communication system, improves the system descending throughput.
Referring to Fig. 2, the flow chart of the transmission method of the MJM configuration information that provides for the embodiment of the invention comprises:
S201: determine the MJM configuration information;
S202: described MJM configuration information is carried in the physical control channel on the expanded MCS PD, perhaps, described MJM configuration information is carried in the physical control channel independently on the MJM configuration territory;
S203: between BS and UE, transmit described MJM configuration information by described physical control channel.
To the MJM analysis of technology, the MJM configuration information that the embodiment of the invention is determined comprises MJM sign, remote subscriber or near-end user sign by top, and/or, the power-division ratios of remote subscriber and near-end user.Specific as follows:
1, at the BS transmitting terminal, the MJM configuration information comprises:
1. whether emission has adopted the MJM modulation;
2. UE belongs to remote subscriber or near-end user;
3. the ER value of remote subscriber and near-end user.
2, at the UE receiving terminal, the MJM configuration information comprises:
1. whether received signal has adopted the MJM modulation;
2. UE belongs to remote subscriber or near-end user;
3. the ER value of remote subscriber and near-end user.
In addition, the MJM configuration information can also comprise the sign which kind of modulation system is indication MJM remote subscriber/near-end user adopt separately, modulation system comprises QPSK or 16QAM etc., if do not comprise this sign, then can give tacit consent to far-end adopts and the relevant identical modulation system of concrete transport service with near-end user, as in the VoIP business, far-end and near-end all adopt QPSK etc.
As previously mentioned, physical control channel comprises PDCCH and PUCCH, and correspondingly, the transmission of MJM configuration information comprises both direction between BS and the UE, the one, and the down direction from BS to UE, the 2nd, the up direction from UE to BS.For down direction, it is mainly which kind of code modulation mode is the BS configuration UE adopt.Owing to increased the configuration of MJM, can on existing MCS PD, append the transmission that bit realizes the MJM configuration information, also can increase MJM configuration territory transmission MJM configuration information newly.For up direction, it mainly is the quantification signal to noise ratio of UE to BS feedback self.Owing to the received signal to noise ratio scope of UE not along with the appearance of MJM enlarges, therefore can reuse existing MCS territory.But when the pairing quantification signal to noise ratio in existing MCS territory can't be mated with the quantification signal to noise ratio of MJM configuration, then need newly-increased MJM configuration territory transmission MJM configuration information.As seen, increasing independent MJM configuration territory in up PUCCH mainly is the system that does not have AMC at those, be convenient to BS and carry out MJM configuration,, when up, can directly utilize existing MCS PD and do not need to pass especially in addition the MJM configuration information if the MCS feedback is arranged in the original system.
Describe in detail below in conjunction with the various aspects of accompanying drawing, comprise the structure of MJM configuration information, and how descending and up direction transmits the MJM configuration information of various forms the embodiment of the invention.Need to prove, below only with two users unite the mapping describe, similar with it for the situation of all the other more users, seldom give unnecessary details.
Referring to Fig. 3, for first kind of MJM configuration information of embodiment of the invention structural representation, in the downlink or uplink direction, all can be by newly-increased independently MJM configuration territory carrying MJM configuration information shown in Figure 3.Particularly, set up the MJM configuration territory of 5bit altogether in PDCCH or PUCCH, wherein, 1bit is used for expression and whether adopts MJM, and 1bit is used to represent remote subscriber or near-end user, and 3bit is used to represent the power-division ratios of remote subscriber and near-end user.Method simple and flexible shown in Figure 3, wide coverage.
In order to reduce the MJM configuration information amount that BS sends, can carry out " compression " to the MJM configuration information.
Referring to Fig. 4,,, all can carry MJM configuration information shown in Figure 4 by newly-increased independently MJM configuration territory or by the expanded MCS PD in the downlink or uplink direction for second kind of MJM configuration information of embodiment of the invention structural representation.If adopt the mode in MJM configuration territory, be specially, in PDCCH or PUCCH, increase independently MJM configuration territory of 4bit, wherein, to described MJM configuration territory serial number is MCS0～MCS14, MCS0 represents non-MJM, MCS1～MCS7 represents the power-division ratios of remote subscriber, MCS8～MCS14 represents the power-division ratios of near-end user, wherein, in up PUCCH, be when the pairing quantification signal to noise ratio in existing MCS territory can't with the situation of the quantification signal to noise ratio coupling of MJM configuration under, need newly-increased MJM configuration territory transmission MJM configuration information.If adopt the mode of expanded MCS PD in descending PDCCH, be specially, by increasing 1bit in the 4bit MCS PD shown in the table 1, use new CQI Index#16～30 to carry as shown in Figure 4 MJM configuration information.For up PUCCH,, can directly adopt existing MCS PD transmission MJM configuration information if when the pairing quantification noise in existing MCS territory can be mated with the quantification signal to noise ratio of MJM configuration.As seen, second kind of MJM configuration information structure that the embodiment of the invention provides only needs by the independent MJM configuration territory of 4bit or appends 1bit and can finish in existing MCS PD, can reduce transinformation, the saving signaling expense than first kind of MJM configuration information structure.
Introduce the third MJM configuration information structure of the embodiment of the invention below.
Referring to Fig. 5, be remote subscriber decoding schematic diagram.Receiving terminal at remote subscriber, because the received signal energy is subjected to channel fading bigger, can only reliably tell the residing quadrant of modulation symbol, and can't tell concrete constellation point, therefore only need to adopt general qpsk demodulator can obtain self information, and with the data of near-end user as interference signal.So for remote subscriber, BS only need indicate it to adopt the QPSK demodulation to get final product, and need not in received signal, whether the superposeed information of near-end user of indicating remote user.
Referring to Fig. 6, be near-end user decoding schematic diagram.At the receiving terminal of near-end user, because channel fading is less, the position that can tell concrete constellation point reliably, so near-end user not only can obtain self information, can also obtain the data of remote subscriber.When carrying out channel-decoding, near-end user only need be taken out the data of correspondence self bit position to decipher and be got final product.
From above analysis as can be known, the receiver of near-end user MJM configuration information completely just can carry out demodulation, therefore can't reduce the MJM information of near-end user; The receiver of remote subscriber can't be told the signal of near-end user and the difference between the noise, as seen for remote subscriber, the ER value of remote subscriber and near-end user and whether adopted not effect of MJM modulation, so the MJM information of remote subscriber further " compression ".Through overcompression, MJM configuration information amount can reduce, and only adopts 3bit can carry the MJM configuration information.
Referring to Fig. 7,,, can carry MJM configuration information shown in Figure 7 by newly-increased independently MJM configuration territory or by the expanded MCS PD at down direction for the third MJM configuration information structural representation of the embodiment of the invention.If adopt the mode in MJM configuration territory, be specially, in PDCCH, increase independently MJM configuration territory of 3bit, wherein, be MCS0～MCS7 to described MJM configuration territory serial number, MCS0 represents non-MJM, MCS1～MCS7 represents the power-division ratios of near-end user.If adopt the mode of expanded MCS PD, be specially, by increasing 1bit in the 4bit MCS PD shown in the table 1, use new CQI Index#16～21 to carry as shown in Figure 7 MJM configuration information.As seen, the third MJM configuration information structure that the embodiment of the invention provides only needs by the independent MJM configuration territory of 3bit or appends 1bit and can finish in existing MCS PD, can reduce transinformation than first kind and second kind of MJM configuration information structure, further the saving signaling expense.

The user at first checks MJM configuration territory in receiving signaling, determine whether adopted MJM on this resource:
[1] if do not adopt MJM, then the MCS PD is the MCS under single User Status, by MCS PD information decoding;
[2] if adopted MJM, then judge it self is remote subscriber or near-end user, adopted which kind of power division:
[2.1] if near-end user is then given tacit consent to remote subscriber and adopted QPSK, near-end user adopts the MCS coded modulation in the MCS PD, and the ER value obtains in MJM configuration territory;
[2.2] if remote subscriber, then single user class of processing mode and non-MJM seemingly, by MCS PD information decoding.
