The method comprises the following steps: UE (User Equipment) obtains a set K containing multiple k values according to the current uplink-downlink ratio, detects whether a downlink sub-frame n-km occupies a PDCCH (Physical Downlink Control Channel) and detects the polymerization degree of CCE (Control Channel Element) occupying the PDCCH, wherein m is an index of the set K; the UE obtains a logic resource index hidden in a PUCCH (Physical Uplink Control Channel) according to the downlink sub-frame occupying the PDCCH and the polymerization degree of the CCE; and when the polymerization degree is greater than 1, the UE selects a physical resource corresponding to any logic resource index hidden in the PUCCH and sends RI information to a base station through the PUCCH on the uplink sub-frame n. Through the invention, the resources hidden in the PUCCH format 1/1a/1b are sufficiently used for sending RI, thereby saving the physical resources of the PUCCH format 2/2a/2b.

Description

A kind of method and terminal of utilizing sub-frame of uplink to send rank indication information
Technical field
The present invention relates to LTE (Long Term Evolution Long Term Evolution) technology, relate in particular to a kind of method of utilizing sub-frame of uplink to send order indication RI information, and a kind of terminal of utilizing sub-frame of uplink to send RI information.
Background technology
In the LTE system, HARQ (hybrid automatic repeat quest mixes automatic repeat requests) The Application of Technology has improved the reliability of communication.Its ACK/NACK (affirmation/non-affirmation) information by feedback determines whether retransmitting old data.For descending HARQ, ACK/NACK is in up PUSCH (Physical Uplink Shared Channel Physical Uplink Shared Channel) or PUCCH (PhysicalUplink Control Channel Physical Uplink Control Channel) feedback.
For TDD (Time Division Duplexing time division duplex) system, system frame structure as shown in Figure 1, ascending-descending subframes asymmetric determined a sub-frame of uplink may need to feed back the ACK/NACK situation of several descending sub frames, and concrete sub-frame configuration sees Fig. 2.For example, when a UE is configured to the TDD ascending-descending subframes when disposing 1, at sub-frame of uplink n=2, need UE demodulation result ACK information or the nack message of feedback two descending sub frame n-7 in front and n-6, feedback relationship is referring to accompanying drawing 3.For the Bunding feedback model, the way of stipulating in the agreement is the 2bitACK/NACK that two descending sub frames produce to be carried out the result that logical AND obtains 1bit feed back at sub-frame of uplink n=2 then.If double fluid obtains the result of 2bit, the method for logical AND is seen accompanying drawing 4.
This 1bit or 2bit informational needs that UE produces feed back to the base station, whether need to retransmit old data by the base station decision.Do not have PUSCH when scheduling when up, these informational needs send to the base station by PUCCH, send on PUCCH form 1a or 1b.For Bunding binding feedback model, about the calculating of the PUCCH logical resource index that sends ACK/NACK information, regulation like this in the agreement at present:
n PUCCH ( 1 ) = ( M - m - 1 ) × N p + m × N p + 1 + n CCE + N PUCCH ( 1 ) ;
Wherein, Np is the total number of CCE of p symbol in the PDCCH, and Np+1 is the total number of CCE of p+1 symbol in the PDCCH; M is the index of the k value of minimum; The index value that the descending sub frame of described minimum k value correspondence takies the initial control channel particle CCE of PDCCH is n CCE Be the PUCCH logical resource that SR (Scheduling Request dispatch request information) and semi-static ACK/NACK are kept in the base station, obtain by the configuration of the RRC (Radio Resource Control radio resource control) of base station layer; M is maximum numbers that this sub-frame of uplink needs feeding back downlink subframe ACK/NACK; In addition, up-downgoing proportioning is passed through broadcast announcement UE by the base station.
Fig. 5 is an example with TDD up-downgoing proportioning 3, obtains the mapping graph (M=3) of PUCCH logical resource index according to above-mentioned formula.

Determined PUCCH to take the size of physical resource (RB Resourceblock),
Figure B2009101799453D0000024
Be worth greatly more, it is many more that PUCCH takies RB.
Therefore the target of system design makes exactly
Figure B2009101799453D0000025
Be worth as much as possible for a short time, and determine
Figure B2009101799453D0000026
The size key is the obtaining value method of m, and the value of regulation m is the m value that makes km (km ∈ K) minimum in the agreement, and UE detects PDCCH at descending sub frame n-km, wherein, gathers the definition of K and sees Fig. 6.In the up-downgoing proportioning 3 of Fig. 6, the set K of sub-frame of uplink 2 is { k 0=7, k 1=6, k 2=11}, UE all detects PDCCH at these three descending sub frames, then finds minimum km=6 in set K, obtains the index m=1 of this km.Among Fig. 5

Obviously, obtain according to the computational methods of present agreement
Figure B2009101799453D00000211
Not optimum method,,, can make during m=0 no matter be from figure or from formula, can find out because also there is littler m value

Littler.
In like manner, all there be the problem same for other up-downgoing proportioning patterns of TDD among Fig. 6, can obtain similar resource mapping graph, can see m value choosing method according to the existing protocol regulation with Fig. 5 with proportioning 3, what obtain is not minimum m value, therefore obtains
Figure B2009101799453D00000213
Neither be inevitable minimum.Therefore applicant's intention provides a kind of method to make
Figure B2009101799453D00000214
Littler, thus it is littler to make PUCCH take RB.
In addition, what RI (indication of Rank Indication order) reflected is the order of spatial channel matrix, UE feeds back to the base station with RI/PMI (the Precoding Matrix Indicator pre-coding matrix index) value of measuring, a best downlink precoding matrix just can be selected according to it in the base station, can effectively eliminate correlation between channels, guarantee MIMO (the Multiple-Input Multiple-Out-put multiple-input and multiple-output) stability of system in each environment.
RI can feed back on PUSCH or PUCCH, and when not having the PUSCH scheduling, RI sends on PUCCH.
In the present realization, when RI and ACK/NACK exist simultaneously, send with PUCCH form 2a or 2b behind the combined coding.At first, RI information is carried out (20, A) coding obtains 20bit information, carries out QPSK (Quadrature Phase Shift Keying quarternary phase-shift keying (QPSK) signal) modulation after the scrambling and obtains 10 symbols; The 1/2bit of ACK/NACK carries out BPSK (Binary Phase ShiftKeying two-phase PSK) separately or the QPSK modulation obtains 1 symbol, 11 sign map is gone up to PUCCH to send at last.
Obviously, some waste resource of above-mentioned implementation method.When RI and ACK/NACK exist simultaneously, send and to optimize again with PUCCH form 2a/2b, because RI has only 1bit or 2bit information.
