In order to save the expense of PUCCH resource, the embodiment of the present invention provides a kind of ascending control information sending and receiving method, in this method, the ascending control channel send mode that terminal is indicated according to base station is on one or more antenna ports, use a PUCCH resource to send ascending control information to base station, base station receives ascending control information in this PUCCH resource.
Referring to Fig. 3, the ascending control information sending method that the embodiment of the present invention provides, comprises the following steps:
Step 30: terminal receives the indication information of the ascending control channel send mode of base station transmission;
Step 31: terminal determines that one for carrying the PUCCH resource of ascending control information; And according to described ascending control channel send mode on one or more antenna ports, use described PUCCH resource to send ascending control information to base station.
Here, terminal can determine that one for carrying the PUCCH resource of ascending control information according to the instruction of base station, or a PUCCH resource fixing or agreement is defined as the PUCCH resource for carrying ascending control information by terminal.A PUCCH resource refers to a resource that PUCCH resource sequence number is corresponding.This PUCCH resource at least comprises the frequency domain resource of described PUCCH, and for example PRB resource, can certainly comprise time domain orthogonal sequence and/or pilot signal.
As a kind of execution mode, in step 30, the indication information of described ascending control channel send mode can comprise the information of pre-coding matrix, accordingly, terminal according to described ascending control channel send mode on one or more antenna ports, use described PUCCH resource to send ascending control information to base station, its specific implementation can be as follows:
First the ascending control information that, terminal is used described pre-coding matrix to send needs carries out precoding processing; Then, terminal is used described PUCCH resource on each antenna port, sends the ascending control information after precoding processing to base station.
As another kind of execution mode, in step 30, the indication information of described ascending control channel send mode can comprise the information that sends the antenna port that uses of ascending control information, accordingly, terminal according to described ascending control channel send mode on one or more antenna ports, use described PUCCH resource to send ascending control information to base station, its specific implementation can be as follows:
Terminal, on the indicated antenna port of the information of described ascending control channel send mode, is used described PUCCH resource to send ascending control information to base station.
Further, terminal can send the RS that ascending control information is corresponding in the following manner:
Mode one, terminal can, according to send mode fixing or agreement, send the pilot signal RS that described ascending control information is corresponding to base station.For example, terminal sends at each antenna port the pilot signal RS that described ascending control information is corresponding simultaneously.Or;
Mode two, terminal, according to described ascending control channel send mode, sends the RS that described ascending control information is corresponding to base station.For example, in the time that the indication information of described ascending control channel send mode comprises the information of pre-coding matrix, terminal is used described pre-coding matrix to carry out precoding processing to RS corresponding to described ascending control information, and sends the RS after precoding processing to base station.Again for example, in the time that the indication information of described ascending control channel send mode comprises the information of pre-coding matrix, terminal is determined on one or more antenna ports and is sent ascending control channel, and send RS to base station on described definite antenna port.Again for example, in the time that the indication information of described ascending control channel send mode comprises the information of antenna port, terminal sends RS on this antenna port to base station.
If terminal sends described RS in same subframe on multiple antenna ports, described multiple RS can be mutually orthogonal by time domain spread spectrum or frequency domain spread spectrum.For example, RS, in the upper transmission of multiple Single Carrier Frequency Division Multiple Access symbols (SC-FDMA symbol), can, by using orthogonal time domain spreading code, make the multiple RS that send on described multiple SC-FDMA symbols orthogonal.Again for example, RS is at multiple resource elements (resource element of frequency domain, RE) upper transmission, can be by using orthogonal RS signal, make the multiple RS that send on described multiple RE orthogonal, described orthogonal RS signal can be the orthogonal PUCCH pilot frequency sequence being defined by 3GPP TS36.211, or any orthogonal sequence.
Other terminal sends the mode of the RS that ascending control information is corresponding and does not get rid of.For example, terminal can be according to the independent instruction in base station, determines the send mode of the corresponding RS of ascending control information, and the send mode of described RS can be different from the send mode of described ascending control information.
The specific implementation of step 30 can be as follows:
First, terminal receives the descending control information format (DCI Format) that base station sends at Physical Downlink Control Channel (PDCCH); Then, terminal obtains the indication information of ascending control channel send mode according to described DCI Format.
Concrete, terminal obtains the indication information of ascending control channel send mode according to described DCI Format, and its specific implementation can be in the following way:
Mode one, terminal reads the indication information bit of ascending control channel send mode from described DCI Format, according to the corresponding relation of the indication information bit of predefined ascending control channel send mode and ascending control channel send mode, determine ascending control channel send mode corresponding to indication information bit reading, or;
Mode two, terminal is determined mask (MASK) corresponding to cyclic redundancy check (CRC) code (CRC) of described DCI Format, according to the corresponding relation of predefined MASK and ascending control channel send mode, determine the ascending control channel send mode that described MASK is corresponding.
Here can determine the MASK that CRC is corresponding according to following formula:

Wherein, b

aP, kfor MASK, c
kfor adding the CRC bit after mask.
The corresponding relation of above-mentioned MASK and ascending control channel send mode can be, the corresponding relation of MASK and pre-coding matrix, or the corresponding relation of MASK and antenna port.
Illustrate, described DCI Format can be for dispatching the descending scheduling signaling of Physical Downlink Shared Channel (PDSCH), or for discharging the DCI Format of descending semi-continuous scheduling.
Further, described terminal receives described DCI format in subframe n, in subframe m, sends described ascending control information according to the ascending control channel send mode of described DCI format instruction, and described subframe m is determined by described subframe n.For example, m=n+K, K is positive integer, concrete value is specified by agreement.
Preferably, terminal is used the antenna port that sends described ascending control information to send detection reference signal (SRS); Or it is orthogonal that described terminal sends the RS of the different antenna port that described ascending control information uses.
In this method, terminal sends the ascending control channel form that described ascending control information uses: the PUCCH format 3 of 3GPP LTE definition, or PUCCH format 1/1a/1b, or PUCCH format 2/2a/2b, or PUCCH format 1b channel is selected (with channel selection).This method directly expanded application in other ascending control channel form.
Referring to Fig. 4, the invention process a kind of ascending control information method of reseptance is provided, comprise the following steps:
Step 40: base station sends the indication information of ascending control channel send mode to terminal;
Step 41: the base station ascending control information that receiving terminal sends in a PUCCH resource.This PUCCH resource is that base station indicating terminal sends the PUCCH resource that ascending control information uses, or fixing/agreement for sending the PUCCH resource of ascending control information.A PUCCH resource refers to a resource that PUCCH resource sequence number is corresponding.This PUCCH resource at least comprises the frequency domain resource of described PUCCH, and for example PRB resource, can certainly comprise time domain orthogonal sequence and/or pilot signal.
As a kind of execution mode, in step 40, the indication information of described ascending control channel send mode can comprise: terminal is carried out the information of the pre-coding matrix that precoding processing uses to ascending control information, or terminal sends the information of the antenna port that ascending control information uses.
Further, RS corresponding to described ascending control information that receiving terminal sends, in the time receiving ascending control information, gone back in base station, and described RS is sent according to the mode of fixing mode or agreement or described ascending control channel send mode by terminal.Certainly, the send mode of other RS is not got rid of, and for example, terminal can be according to the independent instruction in base station, determines the send mode of the corresponding RS of ascending control information, and the send mode of described RS can be different from the send mode of described ascending control information.
The specific implementation of step 40 can be as follows:
Base station sends DCI Format by Physical Downlink Control Channel to terminal, to use this DCI Format instruction ascending control channel send mode.Concrete, can comprise following implementation:
Mode one, base station is according to the corresponding relation of the indication information bit of predefined ascending control channel send mode and ascending control channel send mode, determine the indication information bit that needs the ascending control channel send mode that the ascending control channel send mode of instruction is corresponding, send the DCI Format of the indication information bit that carries described ascending control channel send mode to terminal by Physical Downlink Control Channel, or;
Mode two, MASK corresponding to ascending control channel send mode that needs instruction, according to the corresponding relation of the MASK of predefined CRC and ascending control channel send mode, determined in base station; Determine CRC according to described MASK, and send to terminal the DCI Format that carries this CRC.
Here can determine CRC according to following formula:
c
k＝(b

Wherein, b

kfor adding the CRC bit after mask.
The corresponding relation of above-mentioned MASK and ascending control channel send mode can be, the corresponding relation of MASK and pre-coding matrix, or the corresponding relation of MASK and antenna port.
Illustrate, described DCI Format is the descending scheduling signaling for dispatching PDSCH, or for discharging the DCI Format of descending semi-continuous scheduling.
Further, base station sends described DCI format to described terminal in subframe n, in subframe m, receive the described ascending control information that described terminal sends according to the ascending control channel send mode of described DCI format instruction, described subframe m is determined by described subframe n.For example, m=n+K, K is positive integer, concrete value is specified by agreement.
Preferably, before base station sends the indication information of ascending control channel send mode to terminal, base station can receive the upward signal that described terminal sends, and determines the ascending control channel send mode of the demodulation performance optimum that makes described ascending control channel according to the upward signal of described reception; Accordingly, in step 40, base station sends the indication information of described definite ascending control channel send mode that makes described ascending control channel demodulation performance optimum to terminal.
Concrete, the upward signal that base station receives described terminal transmission can be: base station receives the SRS of described terminal, described SRS sends on the antenna port that sends described ascending control information; Or base station receives described terminal and send the RS of the different antenna port that ascending control information uses, the RS of described different antenna port is orthogonal.
If terminal sends RS in same subframe on multiple antenna ports, described multiple RS can be mutually orthogonal by time domain spread spectrum or frequency domain spread spectrum.For example, RS, in the upper transmission of multiple Single Carrier Frequency Division Multiple Access symbols (SC-FDMA symbol), can, by using orthogonal time domain spreading code, make the multiple RS that send on described multiple SC-FDMA symbols orthogonal.Again for example, RS is at multiple resource elements (resource element of frequency domain, RE) upper transmission, can be by using orthogonal RS signal, make the multiple RS that send on described multiple RE orthogonal, described orthogonal RS signal can be the orthogonal PUCCH pilot frequency sequence being defined by 3GPP TS36.211, or any orthogonal sequence.
In this method, the ascending control channel form that carries described ascending control information is: the PUCCH format 3 of 3GPP LTE definition, or PUCCH format 1/1a/1b, or PUCCH format 2/2a/2b, or PUCCH format 1b with channel selection.This method directly expanded application in other ascending control channel form.
Below the present invention is specifically described:
The present invention proposes the delivery plan of the many antenna ports of a kind of ascending control channel.Its main thought is, for the UE of many antenna ports, according to the instruction of base station, determines the send mode of many antenna ports ascending control channel, and wherein multiple antenna ports use identical uplink control channel resource.
Particularly, the present invention includes following steps:
Step 1: base station sends the indication information of ascending control channel send mode to terminal;
Step 2: terminal is determined the ascending control information of required transmission, and determine a PUCCH resource of carrying described ascending control information; And according to described indication information on one or more antenna port of self, use definite PUCCH resource, send described ascending control information;
Step 3: base station in described PUCCH resource, receiving terminal send ascending control information.
In step 1, the indication information of ascending control channel send mode can be the information of the pre-coding matrix that uses in the time that many antenna ports send ascending control information.Can use described pre-coding matrix to carry out precoding in each resource element (RE).For example, in a RE, needing the symbol that carries ascending control information sending is s, supposes that described pre-coding matrix is W, and in described RE, after precoding, the transmitted signal y at multiple antenna ports can be y=Ws so.Wherein y is the column vector of N x 1, and W is the matrix of N x N, and s is the column vector of N x 1, the antenna port number that wherein N is described terminal.Each element in s can be identical, also can be different.Pre-coding matrix W can be in a precoding matrix codebook C.If N=2, C can comprise following pre-coding matrix C={W1, W2, W3}.Described precoding matrix codebook C is only an embodiment, and other precoding matrix codebook C does not get rid of.
In step 1, the indication information of ascending control channel send mode can be to send the antenna port that ascending control information uses.For example, if terminal is supported two antenna ports, base station can send ascending control information on a notification terminal antenna port therein.The upward signal that base station can send by terminal, determines in multiple antenna ports of terminal a preferably antenna port, for sending described ascending control information.
The indication information of the ascending control channel send mode that in step 1, base station sends can only act on the data symbol of ascending control channel, also can act on data symbol and the frequency pilot sign of ascending control channel simultaneously.Data symbol be in PUCCH resource for sending the OFDM symbol of ascending control information, frequency pilot sign is for sending the OFDM symbol of RS in PUCCH resource.Concrete:
When the indication information of the ascending control channel send mode that base station sends in step 1 only acts on the data symbol of ascending control channel, terminal is only according to this ascending control channel send mode, on one or more antenna port, use the data symbol in PUCCH resource, send described ascending control information.As for the send mode of RS corresponding to ascending control information can be fix or agreement, for example, terminal sends the RS that ascending control information is corresponding on multiple antenna ports simultaneously.
When the indication information of ascending control channel send mode that base station sends in step 1 acts on the data symbol of ascending control channel and frequency pilot sign simultaneously, terminal is except according to this ascending control channel send mode, on one or more antenna port, use the data symbol in PUCCH resource, send outside described ascending control information, also on one or more antenna port, use the frequency pilot sign in PUCCH resource according to this ascending control channel send mode, send the RS that described ascending control information is corresponding.For example, in the time that the indication information of ascending control channel send mode comprises the information of pre-coding matrix, terminal is also used this pre-coding matrix to carry out precoding processing to the RS on frequency pilot sign, and sends the RS after precoding processing to base station.Again for example, in the time that the indication information of described ascending control channel send mode comprises the information of pre-coding matrix, terminal is determined on one or more antenna ports and is sent ascending control information, and send RS to base station on described definite antenna port.Again for example, in the time that the indication information of ascending control channel send mode comprises the information of antenna port, terminal sends corresponding RS at this antenna port.
Certainly, the send mode of described ascending control information and pilot signal can be identical, also can be different.For example, if terminal is supported two antenna ports, a notification terminal antenna port therein in base station sends described ascending control information, simultaneously base station notification terminal therein or all send the frequency pilot sign that described ascending control information is corresponding on antenna port.
In step 1, base station can send by down control channel the indication information of ascending control channel send mode.Down control channel is for carrying certain Downlink Control Information, and described Downlink Control Information also can be called a descending control information format (downlink control information format, DCI format).One or more bit in described DCI format can be used to indicate ascending control channel send mode.The different MASK of the CRC bit of described DCI format also can be used to indicate ascending control channel send mode.For example, suppose that length is that the CRC of the DCI format of 16 bits is b
k, terminal length is that the RNTI of 16 bits is x
rnti, k, two antenna ports M ASKx that length is 16 that are defined as follows
aP, k,
| Ascending control channel antenna port | Antenna ports M ASK |
| Antenna port 0 | <0，0，0，0，0，0，0，0，0，0，0，0，0，0，0，0> |
| Antenna port 1 | <0，0，0，0，0，0，0，0，0，0，0，0，0，0，0，1> |
The CRC bit of described DCI format is obtained by following formula.
c
k＝(b
k+x
rnti，k+x
AP，k)mod2
The CRC bit of the DCI format that terminal sends according to the base station receiving, judges that in two antenna ports M ASK is sent out, thereby determines the antenna port of the required use that sends ascending control information.The MASK of the wherein number of the MASK of above-mentioned antenna port, and antenna port and the corresponding relation of antenna port are only embodiment.
Above-mentioned DCI format shares data channel (physical downlink control channel for dispatching downlink, PDSCH) the descending scheduling signaling (DL grant) of transmission, also can be the DCI format for discharging descending semi-continuous scheduling (semi-persistent scheduling, SPS).
Base station, can be according to the upward signal of described terminal in the time determining the ascending control channel send mode of described terminal, selects preferably ascending control channel send mode.For example, detection reference signal (the sounding reference signal that base station can send at each antenna port according to described terminal, SRS) or the RS of the ascending control channel that sends at each antenna port of described terminal, determine preferably ascending control channel send mode.For example, if base station is used the SRS of described terminal to determine ascending control channel send mode preferably, described terminal is for sending SRS and should be identical for the antenna port that sends described ascending control information.If base station is used the RS of the ascending control channel of described terminal transmission to determine preferably ascending control channel send mode, the RS of the antenna port that the ascending control information correspondence of described terminal transmission is different is orthogonal.The criterion of described preferably ascending control channel send mode can be the demodulation performance of ascending control channel preferably, and for example, described in adopting, preferably ascending control channel send mode can make the received signal to noise ratio of ascending control channel the highest.
If terminal sends RS in same subframe on multiple antenna ports, described multiple RS can be mutually orthogonal by time domain spread spectrum or frequency domain spread spectrum.For example, RS, in the upper transmission of multiple Single Carrier Frequency Division Multiple Access symbols (SC-FDMA symbol), can, by using orthogonal time domain spreading code, make the multiple RS that send on described multiple SC-FDMA symbols orthogonal.Again for example, RS is at multiple resource elements (resource element of frequency domain, RE) upper transmission, can be by using orthogonal RS signal, make the multiple RS that send on described multiple RE orthogonal, described orthogonal RS signal can be the orthogonal PUCCH pilot frequency sequence being defined by 3GPP TS36.211, or any orthogonal sequence.
Ascending control information in the present invention can be upload control ACK/NACK feedback information, can be also other any ascending control informations.
The present invention can be used in the transmission of any ascending control channel form, comprise the PUCCH format 3 of 3GPP LTE definition, PUCCH format 1/1a/1b, PUCCH format 2/2a/2b, or PUCCH format 1b with channel selection.This method directly expanded application in other ascending control channel form.
