Description
Technical field
The present invention relates to wireless communication system, the many antennas that utilize that relate in particular in wireless communication system send the method for information at a plurality of channels.
Background technology
The new generation of wireless communication standard LTE of 3GPP standardization body, its downlink transfer technology is based on OFDM (OFDM); Its uplink technology inserts (SCFDMA) based on single-carrier frequency division multiple access.The LTE system comprises two types frame structure, and the frame structure Class1 adopts Frequency Division Duplexing (FDD) (FDD), and frame structure type 2 adopts time division duplex (TDD).
Fig. 3 is the frame structure of LTE FDD system, and the time span of radio frames (radio frame) is 307200 * T
s=10ms, it is 15360T that each radio frames is divided into 20 length
sThe time slot of=0.5ms, the index range of time slot is 0～19.
Fig. 4 is the frame structure of LTE TDD system.Each length is 307200 * T
sIt is 153600 * T that the radio frames of=10ms is divided into two length
sThe field of=5ms.It is 15360T that each field comprises 8 length
sThe time slot of=0.5ms and 3 special domain, i.e. descending pilot frequency time slot (DwPTS), protection be (GP) and uplink pilot time slot (UpPTS) at interval, the length of these 3 special domain be 30720T
s=1ms.
To the frame structure of LTE FDD and LTE TDD, each time slot comprises a plurality of OFDM (perhaps SCFDMA) symbol, and its CP has two kinds, promptly general CP and lengthening CP.Use the time slot of general CP to comprise 7 OFDM (perhaps SCFDMA) symbol, use the time slot of lengthening CP to comprise 6 OFDM (perhaps SCFDMA) symbol.Each subframe is made of two continuous time slot, and promptly k subframe comprises time slot 2k and time slot 2k+1.
In LTE, the physics running time-frequency resource is divided into a plurality of Resource Block (RB), and RB is the minimum particle size of resource allocation.Each Resource Block comprises M continuous sub-carriers on frequency domain, comprise N continuous OFDM symbol or SCFDMA symbol simultaneously in time.The value of M is 12, and the value of N equals the number of the OFDM symbol or the SCFDMA symbol of a time slot.
Physical Uplink Control Channel (PUCCH) takies the resource at the two ends of band system band, and is respectively to take a RB in two time slots of subframe, thereby has the effect of frequency diversity.As shown in Figure 4, first resource that is used for PUCCH is a RB and second interior high-end RB of frequency band of time slot of frequency band low side in first time slot, and they identify with m=0 in the drawings; First resource that is used for PUCCH is a high-end RB of the interior frequency band of first time slot and a RB of second interior frequency band low side of time slot, and they identify with m=1 in the drawings; The rest may be inferred.
PUCCH comprises and confirms/deny channel (ACK/NACK), channel quality indicating channel (CQI) and schedule request channel (SRI) etc.Between the different PUCCH resources, the PUCCH resource of m=0 among Fig. 5 and m=1 for example, a plurality of PUCCH channels are relations of FDM; In same PUCCH resource, for example in the PUCCH resource of m=0, can multiplexing a plurality of PUCCH channels by the mode of CDM.SCFDMA symbol in each time slot is divided into two groups, is used for transmission of reference signals and control information respectively.On each SCFDMA symbol, the signal that sends is the sequence with approximate permanent envelope zero auto-correlation (CAZAC) character that obtains by computer search, its length is 12, and by its cyclic shift being obtained 12 sequences, these 12 sequences have good auto-correlation and their cross correlation.To the ACK/NACK channel, two groups of SCFDMA symbols of each time slot have carried out the expansion of time domain respectively: here, when comprising 4 or 2 SCFDMA symbols in the group, extended code is that length is 4 or 2 Walsh sign indicating number; When comprising 3 SCFDMA symbols in the group, extended code is that length is 3 Fourier transform sequence.Like this, by in the SCFDMA symbol and the expansion of the two dimension between the symbol can multiplexing more channel, guarantee that simultaneously interference level each other is low.The SRI channel is identical with the ACK/NACK channel architecture.To the CQI channel, do not adopt temporal extension, and a plurality of available cyclic shift that just relies in the SCFDMA symbol is come multiplexing a plurality of CQI channels to each SCFDMA symbol.
In the LTE system, for the peak-to-average ratio (PAPR) that reduces upward signal, thereby reduction increases up covering to the requirement of subscriber equipment power amplifier, has adopted the physical layer transmission technology of single carrier, i.e. SCFDMA.Because the subscriber equipment among the LTE has only a power amplifier, thereby can only drive a transmit antennas at every turn.In order not destroy the single-carrier property of upward signal, can not utilize the multiplex mode of FDM or CDM to send signal at up direction simultaneously, this has caused much between the ascending control channel, perhaps carries out the restriction when multiplexing between uplink data channels and the ascending control channel.
In the standard of the evolution version of LTE, because user device configuration a plurality of power amplifiers, can support transmission information on a plurality of antennas simultaneously, so can utilize this new feature to strengthen between the ascending control channel, the perhaps multiplexing performance between uplink data channels and the ascending control channel, bonding carrier characteristics simultaneously.In addition, can also obtain the space diversity gain of many antenna transmission.

Embodiment one:
Suppose that subscriber equipment need send ACK/NACK and SRI simultaneously, i.e. base station be a user equipment allocation ACK/NACK channel and SRI channel, and hypothesis user device configuration two power amplifiers and antenna.The physical number of bits that note ACK/NACK channel provides is N
AN, the physical number of bits that the SRI channel provides is N
SRI
Subscriber equipment carries out the SRI information of ACK/NACK information and 1 bit obtaining N after the processing such as combined coding
AN+ N
SRIIndividual bit, and be divided into two, the bit number of first piece is N
AN, the bit number of second piece is N
SRIHere, when the physical number of bits of ACK/NACK channel and SR channel is identical, is actually the output bit behind the coding is divided into two.Next, the bit of first piece is mapped to the ACK/NACK channel, and with sending on first antenna; Simultaneously, the bit of second piece is mapped to the SR channel, and with sending on second antenna.The method of the combined coding here need guarantee that ACK/NACK and/or SRI can obtain the gain of coding gain and antenna diversity.
Can send the information of 2 bits in below describing on the hypothesis ACK/NACK channel with the QPSK mode.Two kinds of methods of the physical number of bits of determining ACK/NACK channel and SRI channel are described below.First method:, be 2 so can define the physical number of bits order of each ACK/NACK channel because each ACK/NACK channel can transmit the ACK/NACK information of 2 bits with the modulation system of QPSK.Second method: supposing that each ACK/NACK channel comprises two time slots, and can provide 2 physics bits with the QPSK modulator approach in each time slot, is 4 so can define the physical number of bits order of each ACK/NACK channel.These two kinds of methods can be used for the ACK/NACK channel of LTE system, and, because the SRI channel is identical with the structure of ACK/NACK channel, so N
SRIEqual N
ANBelow hypothesis ACK/NACK channel has identical structure with the SRI channel.
An example to the method for ACK/NACK and SRI combined coding is described below.When not having dispatch request to send, the ACK/NACK information mapping is arrived the ACK/NACK channel, and send with first antenna; Simultaneously, the ACK/NACK information mapping is arrived the SRI channel, and send with second antenna.When dispatch request need send, the ACK/NACK information mapping is arrived the ACK/NACK channel, and send with first antenna; Simultaneously, ACK/NACK information is mapped to the SRI channel after conversion, and sends with second antenna.Here, when directly the ACK/NACK information mapping being arrived ACK/NACK channel or SRI channel,, be to carry out the BPSK modulation to 1 bit ACK/nack message; To 2 bit ACK/nack message, be to carry out the QPSK modulation, for example, and the modulator approach shown in the table 1, here, ' 1 ' represents ACK, and ' 0 ' represents NACK; Then BPSK or QPSK modulation symbol are mapped to ACK/NACK channel or SRI channel.When needs carry out conversion and are mapped to the SRI channel then ACK/NACK information, can be after modulation operations to the conversion of ACK/NACK information, promptly at first ACK/NACK information is modulated, for example the modulator approach of table 1; Then BPSK or the QPSK modulation symbol that generates carried out conversion, for example multiply by (1); Be mapped to the SRI channel at last.When needs carry out conversion and are mapped to the SRI channel then ACK/NACK information, conversion to ACK/NACK information also can be before modulation operations, promptly 1 bit of ACK/NACK or the information of 2 bits are changed, this comes down to a kind of encoding operation, according to identical modulator approach the information on each channel is modulated then, for example, adopt the modulator approach of table 1.Above two kinds of methods can be equivalent, table 2 is to adopt transmission ACK/NACK that above-mentioned second method represents and a kind of method of SRI.
