Show routine, be the UCI that 1 descending carrier is fed back in 1 up-link carrier with ratio 1/1 during X=1, Y=1, and When UCI bits size includes a variety of, such as 10 bits, 20 bits, 30 bits, 40 bits, base station corresponds to each UCI bits distribution PRB（Physical Resource Block, Physical Resource Block）Number, then such as 1,2,3,4, the set being made up of [1,2,3,4] Can be resource block number set C1.In addition, base station corresponds to the in the PRB numbers of each UCI bits distribution, such as 1,2,3,4 One maximum is 4, then the set being made up of the positive integer less than or equal to 4 can be resource block number set C1.

X=1, Y=N, with ratio 1/N, i.e., when 1 up-link carrier feeds back the UCI of N number of descending carrier, base station is distributed for UCI PRB numbers, such as N, 2*N, 3*N, 4*N, then by [N, 2*N, 3*N, 4*N] constitute set can be resource block number set CN.The second maximum that base station is corresponded in the PRB numbers of each UCI bits distribution, such as N, 2*N, 3*N, 4*N is 4*N, then by small The set constituted in the positive integer equal to 4*N can be resource block number set CN.

So as to, set [C1, C2 ... CN] is constituted by C1, C2 ... CN, [C1, C2 ... CN] can be stored in information table, It can be seen that, PRB number configuring conditions when information table not only includes single carrier, while also contains under multi-carrier case, UCI is than especially big Increase added-time PRB number configuring condition.

In addition, for UE angle, optionally, UE can obtain information table by high-level signaling or dynamic signaling configuration Content [C1, C2 ... CN], or UE can be gathered [C1, C2 ... CN] from carrier number or other conditions recessiveness deduction.

Optionally, the transmission method of channel quality information of the embodiment of the present invention, above-mentioned steps 12 can include：

Base station configures UL-grant signalings to indicate the modulation coding mode of re-transmission packet, has channel quality information to touch Hair request, and the resource block of the distribution number, UL-grant is sent to user equipment so that user equipment according to Base station distribution resource block on Uplink Shared Channel independent transmission of channel quality information to base station.

Show routine, according to the multiple word domains of 3GPP_Rel-8 standard configuration UL-grant signalings, such as UL-grant letters I in order_MCS=29, or I_MCS=30, or I_MCS=31, to indicate that the index of modulation coding mode is 29 or 30 or 31, Index 29 or 30 or 31 is expressed as the special modulation coding mode for retransmitting packet, and correspondence upstream data represents to retransmit, wherein, MCS（Modulation and Coding Scheme, modulation coding mode）；CQI-request=1 in UL-grant signalings To have indicated CQI trigger requests, there are CQI trigger requests to represent that base station requires UE feedback of down channel quality information；And N in UL-grant signalings_PRB=n_{_PRB_UCI}(n_{_PRB_UCI}∈N_{_PRB_UCI}), wherein, N_{_PRB_UCI}Represent the collection that the set of PRB numbers is constituted Close [C1, C2 ... CN], n_{_PRB_UCI}Represent a set in C1, C2 ... CN, such as set CN, N_PRBRepresent the PRB of base station distribution A value in number, such as set CN.By configuring the multiple word domains of UL-grant signalings, mutual association indicates PUSCH （Physical Uplink Shared Channel, Physical Uplink Shared Channel）On without UL-SCH data transfers, UE is according to base Stand distribution resource block, on PUSCH individually transmission downlink channel quality information.

According to 3GPP_Rel-8 standards, I_MCS=29, or I_MCS=30, or I_MCS=31, to indicate modulating-coding side The index of formula is 29 or 30 or 31, and index 29 or 30 or 31 is expressed as the special modulation coding mode for retransmitting packet, is different from 0-28 is indexed, therefore not to repeat here.

In addition, UL-grant signalings can support 1 TB（Transport block, transmission block）Transmission, can also be supported 2 TB transmission：

Now, specifically, in above-mentioned steps 12, base station configures UL-grant signalings to indicate the modulation of re-transmission packet Coded system, can include：

Described 1 of correspondence in UL-grant signalings for supporting 1 transport block transmission, base station configuration UL-grant signalings The indicating bit of transmission block（The indicating bit I of such as modulation coding mode_MCS）Indicate the modulation coding mode of re-transmission packet, such as I_MCS =29；

Or, the UL-grant signalings for supporting 2 transport block transmissions, base station configures correspondence institute in UL-grant signalings The indicating bit for stating 2 transmission blocks all indicates to retransmit the modulation coding mode of packet, such as I_MCS=29；

Or, the UL-grant signalings for supporting 2 transport block transmissions, base station configures correspondence institute in UL-grant signalings The indicating bit for stating 1 transmission block in 2 transmission blocks indicates to retransmit the modulation coding mode of packet, such as I_MCS=29.

It can be seen that, UL-grant signalings are based on 3GPP_Rel-8 standards, and the PRB that instruction user equipment is distributed according to base station exists UCI is transmitted on PUSCH, realizes and keeps backwards compatibility with 3GPP_Rel-8 standards, solved on the premise of complexity is not introduced UCI information bits size is more than a definite limitation, the problem of resource-constrained or UCI transmission hydraulic performance decline.

The indicating bit of correspondence at least one transmission block in base station configuration UL-grant signalings（For example by two or two with The combination in upper UL-grant words domain is as indicating bit, and the modulation coding mode and new data packets for for example retransmitting packet are designated as The combination in packet word domain is just passed, or just the modulation coding mode and new data packets of biography packet are designated as retransmitting packet word domain Combination）Indicate that corresponding transmission block is invalid, and configuration UL-grant signalings are asked with having indicated that channel quality information is triggered Ask, and the resource block number distributed, UL-grant signalings are sent to user equipment, distributed so as to obtain user equipment according to base station Resource block on Uplink Shared Channel independent transmission of channel quality information to base station.It should be noted that the resource block of distribution Even if number is not in the corresponding resource block number set of ratio X/Y, base station only configures in UL-grant signalings and corresponded at least The indicating bit of 1 transmission block indicates that corresponding transmission block is invalid, and configures UL-grant signalings to have indicated channel quality letter Cease trigger request, you can the resource block that triggering user equipment is distributed according to base station independent transmission channel matter on Uplink Shared Channel Information is measured to base station.

Specifically, correspondence 1 in the UL-grant signalings for supporting 1 TB transmission, base station configuration UL-grant signalings TB indicating bit indicates 1 TB disable（It is invalid）, and configuring the instruction of UL-grant signalings has channel quality information triggering please Ask, and base station distribution resource block number so that the resource block number distributed according to base station of user equipment up shared Independent transmission of channel quality information is to base station on channel；

Or, the UL-grant signalings for supporting 2 TB transmission, base station configures 1 TB of correspondence in UL-grant signalings Indicating bit indicate that 1 TB is invalid, and configure UL-grant signalings and indicate there is a channel quality information trigger request, and base station point The resource block number matched somebody with somebody so that the resource block number distributed according to base station of user equipment is individually transmitted on Uplink Shared Channel Channel quality information is to base station；

Or, the UL-grant signalings for supporting 2 transport block transmissions, base station configures correspondence 2 in UL-grant signalings Individual TB indicating bit indicates that 2 TB are invalid, and configures UL-grant signalings and indicate there is channel quality information trigger request, and The resource block number of base station distribution so that the resource block number distributed according to base station of user equipment is single on Uplink Shared Channel Only transmission of channel quality information is to base station.

It can be seen that, it is invalid according to TB, and CQI-request=1, user equipment can be triggered independent on Uplink Shared Channel Transmission of channel quality information is to base station.The PRB numbers distributed in conjunction with base station, the resource block that user equipment is distributed according to base station exists Independent transmission of channel quality information is to base station on Uplink Shared Channel.

Meanwhile, the specific word domain of UL-grant signalings is not limited, as long as by configuring the multiple of UL-grant signalings Word domain, triggering user equipment on Uplink Shared Channel independent transmission of channel quality information to base station, user equipment according to Base station distribution resource block on Uplink Shared Channel independent transmission of channel quality information to base station.

Exemplary, such as " the Precoding information of UL-grant signalings（Precoding information）" word domain, it can To indicate the precoding vector for being used for transmitting UCI, recessiveness knows UCI in a CW（Code Word, code word）Upper transmission or two Individual CW（Code word）Upper transmission and the rank of channel matrix（Order）Value.Accordingly it is also possible to configure " Precoding Information " words domain, it is independent on Uplink Shared Channel that other word domains cooperation with UL-grant signalings triggers user equipment Transmission of channel quality information is to base station.

Base station configures UL-grant signalings to indicate the modulation coding mode of re-transmission packet, and new data packets are designated as just Packet is passed, there is channel quality information trigger request, and the resource block number that base station is distributed, so as to obtain user equipment according to base Stand distribution resource block on Uplink Shared Channel independent transmission of channel quality information to base station；It should be noted that distribution Even if resource block number is not in the corresponding resource block number set of ratio X/Y, base station only configures UL-grant signalings to refer to Show the modulation coding mode for retransmitting packet, new data packets are designated as just passing packet, have channel quality information trigger request, i.e., Can trigger the resource block that is distributed according to base station of user equipment on Uplink Shared Channel independent transmission of channel quality information to base station.

Show the I in routine, the multiple word domains of configuration UL-grant signalings, such as UL-grant signalings_MCS=29, it is used to The index for indicating modulation coding mode is 29, and index represents that 29 be the modulation coding mode for retransmitting packet, that is, represents to retransmit number According to bag；NDI（New Data Indicator, new data packets are indicated）For just pass packet, specifically, according to NDI whether be toggle（Invert state）Determine whether just to pass packet, the state that reversion state refers to NDI is different from the state of last time, if on NDI Secondary is 1, after reversion, and this time NDI should be 0, if NDI last time is 0, after reversion, this time NDI should be 1, and otherwise, NDI is non-inverted State, is not just to pass packet, but retransmit packet；CQI-request=1 has CQI to touch to have indicated CQI trigger requests Hair request represents that base station requires UE feedback channel quality information；And N in UL-grant signalings_PRB=n_{_PRB_UCI}(n_{_PRB_UCI}∈ N_{_PRB_UCI}), indicate the PRB numbers of base station distribution.

So, according to I_MCS=29, represent to retransmit packet, but NDI is reversion state, represents just to pass packet, causes UL-grant signalings indicate confusion, then UL-SCH data can not be transmitted on PUSCH, then combine CQI-request=1, Yi Jiji Stand distribution PRB numbers, user equipment can on PUSCH independent transmission of channel quality information.

Similarly, IMCS=30, IMCS=31, are readily applicable to the transmission side of channel quality information of the embodiment of the present invention Method, will not be repeated here.

Or, above-mentioned steps 12 can include：Base station configures UL-grant signalings to indicate the modulation of just biography packet Coded system, new data packets are designated as retransmitting packet, there is channel quality information trigger request, and the resource block that base station is distributed Number so that the resource block that is distributed according to base station of user equipment independent transmission channel quality on the Uplink Shared Channel is believed Cease to base station.Even if it should be noted that the resource block number of distribution is not with the corresponding resource block number set of ratio X/Y In, base station only configures UL-grant signalings and indicates just to pass the modulation coding mode of packet, and new data packets are designated as retransmitting data Bag, there is channel quality information trigger request, you can the resource block that triggering user equipment is distributed according to base station is in Uplink Shared Channel Upper independent transmission of channel quality information is to base station.

Show the I in routine, the multiple word domains of configuration UL-grant signalings, such as UL-grant signalings_MCS=0, to refer to The index for showing modulation coding mode is 0, and index represents that 0 is the first modulation coding mode for passing packet, that is, represents just to pass packet； NDI is non-inverted state, that is, represents to retransmit packet；CQI-request=1 has CQI triggerings to have indicated CQI trigger requests Request represents that base station requires UE feedback channel quality information；And N in UL-grant signalings_PRB=n_{_PRB_UCI}(n_{_PRB_UCI}∈ N_{_PRB_UCI}), indicate the PRB numbers of base station distribution.

So, according to I_MCS=0, represent just to pass packet, but NDI is non-inverted state, represents to retransmit packet, causes UL-grant signalings indicate confusion, then without UL-SCH data transfers on PUSCH, then combine CQI-request=1, and base station The PRB numbers of distribution, user equipment can on PUSCH independent transmission of channel quality information.

In addition, UL-grant signalings can support 1 TB transmission, 2 TB transmission, now, above-mentioned steps can also be supported In 12, base station configures UL-grant signalings to indicate the modulation coding mode of re-transmission packet, can include：

Described 1 of correspondence in UL-grant signalings for supporting 1 transport block transmission, base station configuration UL-grant signalings The indicating bit of transmission block indicates to retransmit the modulation coding mode of packet, and new data packets are designated as just passing packet, or The indicating bit for configuring correspondence 1 transmission block in UL-grant signalings indicates the modulation coding mode of just biography packet, and New data packets are designated as retransmitting packet；

UL-grant signalings for supporting 2 transport block transmissions, base station configures correspondence institute in the UL-grant signalings The indicating bit for stating 2 transmission blocks all indicates to retransmit the modulation coding mode of packet, and new data packets are designated as just passing data The indicating bit of correspondence 2 transmission blocks all indicates just to pass the modulation of packet in bag, or the configuration UL-grant signalings Coded system, and new data packets are designated as retransmitting packet；

Or, the UL-grant signalings for supporting 2 transport block transmissions, base station configures correspondence institute in UL-grant signalings The indicating bit for stating 1 transmission block in 2 transmission blocks is indicated to retransmit the modulation coding mode of packet, and new data packets are designated as The indicating bit for just passing 1 transmission block in correspondence 2 transmission blocks in packet, or configuration UL-grant signalings indicates just to pass The modulation coding mode of packet, and new data packets are designated as retransmitting packet.
