Description

Method for transmitting information on multiple channels using multiple antennas

technical field

The present invention relates to a wireless communication system, more specifically to a method for transmitting information on multiple channels using multiple antennas in the wireless communication system.

Background technique

The next-generation wireless communication standard LTE of the 3GPP standardization organization, its downlink transmission technology is based on Orthogonal Frequency Division Multiplexing (OFDM); its uplink transmission technology is based on Single Carrier Frequency Division Multiple Access (SCFDMA). The LTE system includes two types of frame structures, frame structure type 1 adopts frequency division duplex (FDD), and frame structure type 2 adopts time division duplex (TDD).

Fig. 3 is the frame structure of the LTE FDD system, the time length of the radio frame (radio frame) is 307200×T _s =10ms, each radio frame is divided into 20 time slots whose length is 15360T _s =0.5ms, and the index of the time slot The range is 0-19.

Fig. 4 is the frame structure of the LTE TDD system. Each radio frame with a length of 307200×T _s =10 ms is equally divided into two half frames with a length of 153600×T _s =5 ms. Each half-frame contains 8 time slots with a length of 15360T _s =0.5ms and 3 special domains, namely downlink pilot time slot (DwPTS), guard interval (GP) and uplink pilot time slot (UpPTS). The sum of the lengths of the special domains is 30720T _s =1 ms.

For the frame structure of LTE FDD and LTE TDD, each time slot contains multiple OFDM (or SCFDMA) symbols, and there are two types of CPs, namely general CP and extended CP. A time slot using a general CP includes 7 OFDM (or SCFDMA) symbols, and a time slot using an extended CP includes 6 OFDM (or SCFDMA) symbols. Each subframe consists of two consecutive time slots, that is, the kth subframe includes time slot 2k and time slot 2k+1.

In LTE, physical time-frequency resources are divided into multiple resource blocks (RBs), and RBs are the minimum granularity of resource allocation. Each resource block includes M consecutive subcarriers in frequency domain and N consecutive OFDM symbols or SCFDMA symbols in time. The value of M is 12, and the value of N is equal to the number of OFDM symbols or SCFDMA symbols in one slot.

The Physical Uplink Control Channel (PUCCH) occupies resources at both ends of the system frequency band, and occupies one RB in each of the two time slots of the subframe, thus having the effect of frequency diversity. As shown in Figure 4, the first resource used for PUCCH is an RB at the low end of the frequency band in the first time slot and an RB at the high end of the frequency band in the second time slot, which are identified by m=0 in the figure; The first resource used for PUCCH is an RB at the high end of the frequency band in the first slot and an RB at the low end of the frequency band in the second slot, which are marked by m=1 in the figure; and so on.

The PUCCH includes an acknowledgment/denial channel (ACK/NACK), a channel quality indicator channel (CQI) and a scheduling request channel (SRI) and the like. Between different PUCCH resources, such as the PUCCH resources of m=0 and m=1 in Figure 5, multiple PUCCH channels are in the relationship of FDM; The mode can multiplex multiple PUCCH channels. The SCFDMA symbols in each time slot are divided into two groups, which are used to transmit reference signals and control information respectively. On each SCFDMA symbol, the transmitted signal is a sequence with approximately constant envelope zero autocorrelation (CAZAC) properties obtained by computer search, its length is 12, and 12 sequences are obtained by cyclic shifting, which The 12 sequences have good autocorrelation and cross-correlation properties. For the ACK/NACK channel, two groups of SCFDMA symbols in each time slot are respectively extended in the time domain: here, when the group contains 4 or 2 SCFDMA symbols, the extension code is a Walsh code with a length of 4 or 2; when When a group contains 3 SCFDMA symbols, the spreading code is a Fourier transform sequence with a length of 3. In this way, more channels can be multiplexed through two-dimensional expansion within and between SCFDMA symbols, while ensuring a low level of mutual interference. The SRI channel has the same structure as the ACK/NACK channel. For CQI channels, time spreading for each SCFDMA symbol is not employed, but multiple CQI channels are multiplexed relying on multiple available cyclic shifts within the SCFDMA symbol.

In the LTE system, in order to reduce the peak-to-average ratio (PAPR) of the uplink signal, thereby reducing the requirements on the power amplifier of the user equipment and increasing the uplink coverage, a single-carrier physical layer transmission technology, namely SCFDMA, is adopted. Since the user equipment in LTE has only one power amplifier, it can only drive one transmitting antenna at a time. In order not to destroy the single-carrier characteristics of the uplink signal, the FDM or CDM multiplexing method cannot be used to send signals in the uplink direction at the same time, which leads to multiplexing between many pairs of uplink control channels, or between uplink data channels and uplink control channels. time limit.

In the evolved version of the LTE standard, because the user equipment is equipped with multiple power amplifiers, which can support simultaneous transmission of information on multiple antennas, this new feature can be used to enhance the communication between the uplink control channel, or between the uplink data channel and the uplink control channel. Multiplexing performance between channels while ensuring single carrier characteristics. In addition, the space diversity gain of multi-antenna transmission can also be obtained.

Detailed ways

Assuming that the sending device needs to send P pieces of different information, the information here can be data; it can be control signaling; it can also be other physical signals. Correspondingly, it is assumed that P independent channel resources of different types are allocated to the sending device, and the relationship between these channel resources is FDM and CDM. It is further assumed that the sending device is configured with at least M power amplifiers, so that M antennas can be used to transmit information at the same time, where P is greater than or equal to M.

As shown in Figure 1 is the sending device and method of the present invention:

First, operations such as encoding are performed on the P pieces of different information, and the output information is mapped to M independent channel resources. Several possible approaches are described below.

The first method is to perform independent encoding and other operations on the P pieces of information when P is equal to M, and map them to an independent channel resource for transmission.

The second method is to perform joint encoding and other operations on the P pieces of information, and divide them into M blocks, so as to be mapped to M independent channel resources for transmission, where the number of bits in each block depends on the physical number of bits. When M is smaller than P, M independent channel resources are selected from the P independent channel resources for information transmission. The joint coding here may refer to performing a joint coding on the P pieces of information; it may also refer to grouping the P pieces of information first, and then performing joint coding on the information of each group respectively.

The third method is to perform joint coding and other operations on some of the P pieces of information, and divide them into M blocks, so as to be mapped to M independent channel resources for transmission. Here, the number of bits in each block depends on its mapping to The number of physical bits of the channel resource. Here, another part of the P pieces of information may be transmitted by adopting different blocking methods.

The fourth method is to perform joint coding and other operations on some of the P pieces of information, and divide them into M blocks, so as to be mapped to M independent channel resources for transmission. Here, the number of bits in each block depends on its mapping to The number of physical bits of the channel resource. Here, when M is smaller than P, different M independent channel resources for information transmission may be selected from the P independent channel resources to transmit another part of the P information.

The fifth method is to perform joint coding and other operations on some of the P pieces of information, and divide them into M blocks, so as to be mapped to M independent channel resources for transmission. Here, the number of bits of each block depends on its mapping to The number of physical bits of the channel resource. Here, another part of the P pieces of information is transmitted by adopting different block methods and selecting different M independent channel resources for information transmission from the P pieces of independent channel resources.

Next, M power amplifiers are used to drive, and different antennas are used to transmit signals on different independent channel resources.

As shown in Figure 2 is the receiving device and method of the present invention:

The receiving device sends the received signal to the physical channel demultiplexer through the processing of the receiving antenna and the receiving device, so as to obtain M independent channel resource signals by demultiplexing. Next, the signals of the M independent channel resources are sent to the decoding module for decoding and other operations to obtain P pieces of transmitted information.

For the encoding method of the first sending device, M is equal to P, and the receiving device performs independent decoding and other operations on the signal on each channel resource, so as to obtain a sent message.

For the second encoding method of the sending device, the receiving device performs operations such as joint decoding on the signals on M channel resources, so as to obtain P pieces of transmitted information.

For the third encoding method of the sending device, the receiving device performs operations such as joint decoding on the signals on M channel resources according to various possible block methods, so as to obtain P pieces of transmitted information.

For the fourth coding method of the sending device, the receiving device detects various possible signals on the M channel resources occupied by the sending device, and performs operations such as joint decoding to obtain P pieces of sent information.

For the fifth coding method of the sending device, the receiving device detects various possible signals on the M channel resources occupied by the sending device, and performs joint decoding and other operations according to various possible block methods, so as to obtain P information sent.

Example

This section presents the embodiments of the invention. In order to avoid making the description of this patent too lengthy, in the following description, detailed descriptions of functions or devices that are well known to the public are omitted. The CQI information in the following embodiments may be CQI information in the strict sense, or generally refer to CQI, precoding matrix indication (PMI) and channel order indication (RI) related to multiple input multiple output technology (MIMO) channel information.

Embodiment one:

It is assumed that the user equipment needs to send ACK/NACK and SRI at the same time, that is, the base station allocates an ACK/NACK channel and an SRI channel to the user equipment, and it is assumed that the user equipment is configured with two power amplifiers and antennas. Note that the number of physical bits provided by the ACK/NACK channel is N _AN , and the number of physical bits provided by the SRI channel is N _SRI .

The user equipment performs joint encoding on ACK/NACK information and 1-bit SRI information to obtain N _AN + N _SRI bits, which are divided into two blocks. The number of bits in the first block is N _AN , and the number of bits in the second block The number of bits is N _SRI . Here, when the number of physical bits of the ACK/NACK channel and the SR channel are the same, the coded output bits are actually divided into two equal blocks. Next, the bits of the first block are mapped to the ACK/NACK channel and sent on the first antenna; at the same time, the bits of the second block are mapped to the SR channel and sent on the second antenna. The joint coding method here needs to ensure that ACK/NACK and/or SRI can obtain coding gain and antenna diversity gain.

In the following description, it is assumed that 2-bit information can be sent in QPSK mode on the ACK/NACK channel. Two methods of determining the number of physical bits of the ACK/NACK channel and the SRI channel are described below. The first method: because each ACK/NACK channel can transmit 2-bit ACK/NACK information in the QPSK modulation mode, it can be defined that the number of physical bits of each ACK/NACK channel is 2. The second method: assuming that each ACK/NACK channel contains two time slots, and QPSK modulation method can be used to provide 2 physical bits in each time slot, so the number of physical bits of each ACK/NACK channel can be defined as 4. These two methods can be used for the ACK/NACK channel in the LTE system, and since the structure of the SRI channel and the ACK/NACK channel are the same, N _SRI is equal to N _AN . It is assumed below that the ACK/NACK channel and the SRI channel have the same structure.

One example of a method of jointly encoding ACK/NACK and SRI is described below. When no scheduling request needs to be sent, map the ACK/NACK information to the ACK/NACK channel and use the first antenna to send it; at the same time, map the ACK/NACK information to the SRI channel and use the second antenna to send it. When a scheduling request needs to be sent, map the ACK/NACK information to the ACK/NACK channel and use the first antenna to send it; at the same time, map the ACK/NACK information to the SRI channel after conversion and use the second antenna to send it . Here, when the ACK/NACK information is directly mapped to the ACK/NACK channel or the SRI channel, BPSK modulation is performed on 1-bit ACK/NACK information; QPSK modulation is performed on 2-bit ACK/NACK information, for example, Table 1 In the modulation method shown, here, '1' represents ACK, and '0' represents NACK; then map BPSK or QPSK modulation symbols to ACK/NACK channel or SRI channel. When the ACK/NACK information needs to be transformed and then mapped to the SRI channel, the transformation of the ACK/NACK information can be performed after the modulation operation, that is, the ACK/NACK information is first modulated, such as the modulation method in Table 1; and then the generated The BPSK or QPSK modulation symbol is transformed, for example, multiplied by (-1); finally mapped to the SRI channel. When the ACK/NACK information needs to be transformed and then mapped to the SRI channel, the transformation of the ACK/NACK information can also be performed before the modulation operation, that is, the 1-bit or 2-bit information of the ACK/NACK is changed, which is essentially is an encoding operation, and then the information on each channel is modulated according to the same modulation method, for example, the modulation method in Table 1 is adopted. The above two methods may be equivalent, and Table 2 is a method of sending ACK/NACK and SRI represented by the above-mentioned second method.

Table 1: Modulation methods of BPSK and QPSK

Table 2: The first joint coding method of ACK/NACK and SRI

A second example of a method of jointly encoding ACK/NACK and SRI is described below. According to the method of defining the number of physical bits of the ACK/NACK channel or SRI channel according to the first method above, the number of physical bits that can be carried by each ACK/NACK channel or SRI channel is 2 by using the QPSK modulation method. Therefore, the sum of the physical bits of the two channels is 4. In this way, ACK/NACK and SRI can be jointly coded into 4 bits, so that the first two bits are mapped to the ACK/NACK channel and sent with the first antenna; the latter Two bits are mapped to the SRI channel and transmitted using the second antenna. One form of this joint encoding is described as shown in Table 3. The present invention does not limit the specific method of joint encoding.

In Table 3, when there is no scheduling request to be sent, repeat 1-bit ACK/NACK information 4 times to obtain 4 bits; or for 2-bit ACK/NACK, repeat 2 times to obtain 4 bits. In this example, the information sent on the ACK/NACK channel and the SRI channel is the same. When a scheduling request needs to be sent, first, repeat 4 times for 1-bit ACK/NACK information to obtain 4 bits; or for 2-bit ACK/NACK, repeat 2 times to obtain 4 bits; Invert the first and fourth bits, or invert the second and third of the four bits. In this example, one of the two bits sent on the ACKNACK channel and the SRI channel is respectively inverted compared to when no scheduling request needs to be sent. The advantage of this encoding is that when receiving, both ACK/NACK and SRI can obtain the gain of antenna diversity.

Table 3: The second ACK/NACK and SRI joint encoding method

A third example of a method of jointly encoding ACK/NACK and SRI is described below. According to the above second method of defining the number of physical bits of the ACK/NACK channel or SRI channel, the number of physical bits that can be carried by each ACK/NACK channel or SRI channel is 4. Therefore, the sum of the physical bits of the two channels is 8. In this way, ACK/NACK and SRI can be jointly coded into 8 bits, so that the first 4 bits are mapped to the ACK/NACK channel and sent with the first antenna; The last 4 bits are mapped to the SRI channel and sent using the second antenna. The present invention does not limit the specific method of joint encoding.

Embodiment two:

It is assumed that the user equipment needs to send CQI and ACK/NACK at the same time, that is, the base station allocates a CQI channel and an ACK/NACK channel for the user equipment, and it is assumed that the user equipment is configured with two power amplifiers and antennas. Note that the number of physical bits provided by the CQI channel is N _CQI , and the number of physical bits provided by the ACK/NACK channel is N _AN . For example, assuming that the ACK/NACK channel contains two time slots, and QPSK modulation method can be used to provide 2 physical bits in each time slot, it can be defined that the number of physical bits of each ACK/NACK channel is N _AN =4.

After the user equipment performs joint coding on the CQI information and the ACK/NACK information, the output bits are divided into two blocks, wherein the number of bits in the first block is N _CQI , and the number of bits in the second block is N _AN . Then, the bits of the first block are mapped to the CQI channel and sent on the first antenna; at the same time, the bits of the second block are mapped to the ACK/NACK channel and sent on the second antenna.

Embodiment three:

Assuming that the user equipment needs to send CQI, ACK/NACK and SRI at the same time, that is, the base station allocates a CQI channel, an ACK/NACK and an SRI channel for the user equipment. And it is assumed that the user equipment is configured with two power amplifiers and antennas. Note that the number of physical bits provided by the CQI channel is N _CQI , the number of physical bits provided by the ACK/NACK channel is N _AN , and the number of physical bits provided by the SRI channel is N _SRI . For example, assuming that the ACK/NACK channel contains two time slots, and QPSK modulation method can be used to provide 2 physical bits in each time slot, it can be defined that the number of physical bits of each ACK/NACK channel is N _AN =4. Assuming further that the structures of the SRI channel and the ACK/NACK channel are the same, then N _SRI is equal to N _AN .

The first method of sending CQI, ACK/NACK and SRI. The user equipment obtains N _CQI +N _AN bits after performing joint coding and other processing on the CQI information and the ACK/NACK information. When there is no scheduling request to be sent, divide N _CQI + N _AN bits into two blocks, the number of bits in the first block is N _CQI , and the number of bits in the second block is N _AN ; the bit mapping of the first block to the CQI channel and send it on one antenna; at the same time, the bits of the second block are mapped to the ACK/NACK channel and sent on the other antenna. Note: when there is no scheduling request to be sent, the method of sending CQI and ACK/NACK is the method in the second embodiment. When there is a scheduling request to be sent, the N _CQI +N _AN bits are divided into two blocks. The block method here can be different from the block method when there is no scheduling request to be sent, thereby increasing the reliability of SRI detection. First The number of bits of the first block is N _CQI , and the number of bits of the second block is N _AN ; the bits of the first block are mapped to the CQI channel and transmitted with one antenna; at the same time, the bits of the second block are mapped to the SRI channel , and use another antenna to transmit. A method of blocking the jointly encoded output bits is described below. When there is no scheduling request to be sent, the first _NCQI bits of the coded output bits are the first block, and the next N _AN bits are the second block; when there is a scheduling request to be sent, the last _NCQI bits of the coded output bits are bits is the first block, and the first N _AN bits are the second block.

The second method of sending CQI, ACK/NACK and SRI. The user equipment performs joint encoding processing on CQI, ACK/NACK and 1-bit SRI to obtain N _CQI + N _AN bits, which are divided into two blocks, where the number of bits in the first block is N _CQI , and the number of bits in the second block The number is N _AN . Then, the bits of the first block are mapped to the CQI channel and sent on one antenna; at the same time, the bits of the second block are mapped to the SRI channel or ACK/NACK channel and sent on the other antenna.

Embodiment four:

It is assumed that the user equipment needs to send CQI and SRI at the same time, that is, the base station allocates a CQI channel and an SRI channel for the user equipment, and it is assumed that the user equipment is configured with two power amplifiers and antennas. Note that the number of physical bits provided by the CQI channel is N _CQI , and the number of physical bits provided by the SRI channel is N _SRI . For example, assuming that the SRI channel contains two time slots, and QPSK modulation method can be used to provide 2 physical bits in each time slot, it can be defined that the number of physical bits of each SRI channel is N _SRI =4.

The first transmission method is that the user equipment outputs N _CQI + N _SRI bits after joint coding of CQI information and 1-bit SRI information, and then the output bits are divided into two blocks, where the number of bits in the first block is N _CQI , the number of bits of the second block is N _SRI . Then, the bits of the first block are mapped to the CQI channel and transmitted with the first antenna; at the same time, the bits of the second block are mapped to the SRI channel and transmitted with the second antenna. When it is necessary to distinguish from the case of jointly encoding CQI and ACK/NACK and sending them on the CQI channel and the SRI channel in Embodiment 3, the block method for N _CQI + N _SRI output bits here can be the same as Embodiment 3 The method of partitioning is different. For example, assume that in Embodiment 3, when there is a scheduling request to be sent, the last N _CQI bits of the N _CQI + N _SRI coded output bits are the first block, and the first N _SRI bits are the second block; then In this embodiment, the first NCQI bits _{of the NCQI} + _NSRI coded output bits can be used as the first block, and the last N _SRI bits can be used as the second block.

The second transmission method is that the user equipment outputs N _CQI + N _SRI bits after encoding and other processing of the CQI information. When there is no scheduling request to be sent, the N _CQI + N _SRI bits are divided into two blocks. The first block The number of bits of N _CQI is N CQI , and the number of bits of the second block is N _SRI ; the bits of the first block are mapped to the CQI channel and transmitted with one antenna; at the same time, the bits of the second block are mapped to the SRI channel and used Another antenna comes up to transmit. When there is a scheduling request to be sent, the _NCQI + N _SRI bits are divided into two blocks. The block method here is different from the block method when there is no scheduling request to be sent. The number of bits in the first block is _NCQI , The number of bits in the second block is N _SRI ; then, the bits of the first block are mapped to the CQI channel and sent on one antenna; at the same time, the bits of the second block are mapped to the SRI channel and sent on the other antenna send. A method of blocking the jointly encoded output bits is described below. When there is no scheduling request to be sent, the first N _CQI bits of the coded output bits are the first block, and the next N _SRI bits are the second block; when there is a scheduling request to be sent, the last N _CQI bits of the coded output bits are bits is the first block, and the first N _SRI bits are the second block.
