技术领域 technical field
本发明涉及无线通信系统,更具体的说涉及在无线通信系统中的利用多天线在多个信道发送信息的方法。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.
背景技术 Background technique
3GPP标准化组织的新一代无线通信标准LTE,其下行传输技术基于正交频分复用(OFDM);其上行传输技术基于单载波频分多址接入(SCFDMA)。LTE系统包含两种类型的帧结构,帧结构类型1采用频分双工(FDD),帧结构类型2采用时分双工(TDD)。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).
图3是LTE FDD系统的帧结构,无线帧(radio frame)的时间长度是307200×Ts=10ms,每个无线帧分为20个长度为15360Ts=0.5ms的时隙,时隙的索引范围是0~19。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.
图4是LTE TDD系统的帧结构。每个长度为307200×Ts=10ms的无线帧等分为两个长度为153600×Ts=5ms的半帧。每个半帧包含8个长度为15360Ts=0.5ms的时隙和3个特殊域,即下行导频时隙(DwPTS)、保护间隔(GP)和上行导频时隙(UpPTS),这3个特殊域的长度的和是30720Ts=1ms。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.
对LTE FDD和LTE TDD的帧结构,每个时隙包含多个OFDM(或者SCFDMA)符号,其CP有两种,即一般CP和加长CP。使用一般CP的时隙包含7个OFDM(或者SCFDMA)符号,使用加长CP的时隙包含6个OFDM(或者SCFDMA)符号。每个子帧由两个连续的时隙构成,即第k个子帧包含时隙2k和时隙2k+1。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.
在LTE中,物理时频资源划分为多个资源块(RB),RB是资源分配的最小粒度。每个资源块在频域上包含M个连续的子载波,同时在时间上包含N个连续的OFDM符号或者SCFDMA符号。M的值是12,N的值等于一个时隙的OFDM符号或者SCFDMA符号的个数。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.
物理上行控制信道(PUCCH)占用系统频带的两端的资源,并且是在子帧的两个时隙内各占用一个RB,从而具有频率分集的效果。如图4所示,第一个用于PUCCH的资源是第一个时隙内频带低端的一个RB和第二个时隙内频带高端的一个RB,它们在图中用m=0标识;第一个用于PUCCH的资源是第一个时隙内频带高端的一个RB和第二个时隙内频带低端的一个RB,它们在图中用m=1标识;依此类推。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.
PUCCH包括确认/否认信道(ACK/NACK),信道质量指示信道(CQI)和调度请求信道(SRI)等。不同的PUCCH资源之间,例如图5中的m=0和m=1的PUCCH资源,多个PUCCH信道是FDM的关系;在同一个PUCCH资源,例如m=0的PUCCH资源内,通过CDM的方式可以复用多个PUCCH信道。每个时隙内的SCFDMA符号分为两组,分别用来传输参考信号和控制信息。在每个SCFDMA符号上,发送的信号是通过计算机搜索得到的具有近似的恒包络零自相关(CAZAC)性质的序列,其长度为12,并通过对其循环移位得到12个序列,这12个序列具有好的自相关和互相关特性。对ACK/NACK信道,每个时隙的两组SCFDMA符号分别进行了时域的扩展:这里,当组内包含4或者2个SCFDMA符号时,扩展码是长度为4或者2的Walsh码;当组内包含3个SCFDMA符号时,扩展码是长度为3的傅立叶变换序列。这样,通过SCFDMA符号内和符号之间的二维的扩展可以复用更多的信道,同时保证相互之间的干扰水平低。SRI信道与ACK/NACK信道结构相同。对CQI信道,不采用对各个SCFDMA符号的时间扩展,而只是依赖SCFDMA符号内的多个可用的循环移位来复用多个CQI信道。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.
在LTE系统中,为了降低上行信号的峰平比(PAPR),从而降低对用户设备功率放大器的要求,增加上行覆盖,采用了单载波的物理层传输技术,即SCFDMA。由于LTE中的用户设备只有一个功放,从而每次只能驱动一根发射天线。为了不破坏上行信号的单载波特性,不能利用FDM或者CDM的复用方式同时在上行方向发送信号,这导致了很多对上行控制信道之间,或者上行数据信道和上行控制信道之间进行复用时的限制。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.
在LTE的演进版本的标准中,因为用户设备配置了多个功放,可以支持同时在多个天线上发送信息,所以可以利用这个新特征来增强上行控制信道之间,或者上行数据信道和上行控制信道之间的复用性能,同时保证单载波特性。另外,还可以得到多天线发送的空间分集增益。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.

具体实施方式Detailed ways
假设发送设备需要发送P个不同的信息,这里的信息可以是数据;可以是控制信令;也可以是其他的物理信号。相应地,假设为发送设备分配了P个不同类型的独立信道资源,这些信道资源之间是FDM、CDM的关系。进一步假设发送设备至少配置了M个功率放大器,从而可以同时利用M个天线发射信息,这里P大于等于M。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.
如图1所示是本发明的发送设备和方法:As shown in Figure 1 is the sending device and method of the present invention:
首先,对这P个不同的信息进行编码等操作,输出的信息映射到M个独立信道资源上。下面描述几种可能的处理方法。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.
第一种方法是当P等于M时,对这P个信息分别进行独立的编码等操作,并分别映射到一个独立信道资源上发送。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.
第二种方法是对这P个信息进行联合编码等操作之后,并分为M块,从而映射到M个独立信道资源上发送,这里每个块的比特数取决于其映射到信道资源的物理比特数目。当M小于P时,从P个独立信道资源中选择M个独立信道资源用于信息传输。这里的联合编码可以是指对P个信息进行一次联合编码;也可以是指首先把P个信息分组,然后对每组的信息分别进行联合编码。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.
第三种方法是对这P个信息中的一部分信息进行联合编码等操作之后,并分为M块,从而映射到M个独立信道资源上发送,这里每个块的比特数取决于其映射到信道资源的物理比特数目。这里,可以通过采用不同的分块方法来传输P个信息中的另一部分信息。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.
第四种方法是对这P个信息中的一部分信息进行联合编码等操作之后,并分为M块,从而映射到M个独立信道资源上发送,这里每个块的比特数取决于其映射到信道资源的物理比特数目。这里,当M小于P时,可以从P个独立信道资源中选择不同的M个用于信息传输的独立信道资源来传输P个信息中的另一部分信息。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.
第五种方法是对这P个信息中的一部分信息进行联合编码等操作之后,并分为M块,从而映射到M个独立信道资源上发送,这里每个块的比特数取决于其映射到信道资源的物理比特数目。这里,通过采用不同的分块方法,和从P个独立信道资源中选择不同的M个用于信息传输的独立信道资源,来传输P个信息中的另一部分信息。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.
接下来,用M个功率放大器驱动,在不同的独立信道资源上用不同的天线来发送信号。Next, M power amplifiers are used to drive, and different antennas are used to transmit signals on different independent channel resources.
如图2所示是本发明的接收设备和方法:As shown in Figure 2 is the receiving device and method of the present invention:
接收设备通过接收天线和接收装置的处理,把接收到的信号送入物理信道解复用器,从而解复用得到M个独立信道资源的信号。接下来这M个独立信道资源的信号送入解码模块进行解码等操作得到P个发送的信息。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.
对第一种发送设备的编码方法,M等于P,接收设备对每个信道资源上的信号进行独立的解码等操作,从而得到一个发送的信息。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.
对第二种发送设备的编码方法,接收设备对M个信道资源上的信号进行联合解码等操作,从而得到P个发送的信息。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.
对第三种发送设备的编码方法,接收设备对M个信道资源上的信号按照各种可能的分块方法进行联合解码等操作,从而得到P个发送的信息。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.
对第四种发送设备的编码方法,接收设备检测各种可能的被发送设备占用的M个信道资源上的信号,并进行联合解码等操作,从而得到P个发送的信息。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.
对第五种发送设备的编码方法,接收设备检测各种可能的被发送设备占用的M个信道资源上的信号,并按照各种可能的分块方法,进行联合解码等操作,从而得到P个发送的信息。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.
实施例Example
本部分给出了该发明的实施例,为了避免使本专利的描述过于冗长,在下面的说明中,略去了对公众熟知的功能或者装置等的详细描述。以下各实施例中的CQI信息,可以是严格意义上的CQI信息,也可以泛指CQI、预编码矩阵指示(PMI)和信道阶数指示(RI)等多入多出技术(MIMO)相关的信道信息。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.
实施例一:Embodiment one:
假设用户设备需要同时发送ACK/NACK和SRI,即基站为用户设备分配了一个ACK/NACK信道和一个SRI信道,并假设用户设备配置了两个功率放大器和天线。记ACK/NACK信道提供的物理比特数为NAN,SRI信道提供的物理比特数为NSRI。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 .
用户设备对ACK/NACK信息和1比特的SRI信息进行联合编码等处理后得到NAN+NSRI个比特,并分为两块,第一个块的比特数是NAN,第二个块的比特数是NSRI。这里,当ACK/NACK信道和SR信道的物理比特数相同时,实际上是把编码后的输出比特等分为两块。接下来,第一个块的比特映射到ACK/NACK信道,并用第一根天线上来发送;同时,第二个块的比特映射到SR信道,并用第二根天线上来发送。这里的联合编码的方法需要保证ACK/NACK和/或SRI能够获得编码增益和天线分集的增益。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.
以下描述中假设ACK/NACK信道上可以用QPSK方式来发送2个比特的信息。下面描述确定ACK/NACK信道和SRI信道的物理比特数的两种方法。第一种方法:因为每个ACK/NACK信道可以用QPSK的调制方式传输2个比特的ACK/NACK信息,所以可以定义每个ACK/NACK信道的物理比特数目是2。第二种方法:假设每个ACK/NACK信道包含两个时隙,并且在每个时隙内可以用QPSK调制方法提供2个物理比特,所以可以定义每个ACK/NACK信道的物理比特数目是4。这两种方法可以用于LTE系统中的ACK/NACK信道,并且,因为SRI信道和ACK/NACK信道的结构相同,所以NSRI等于NAN。以下假设ACK/NACK信道和SRI信道具有相同的结构。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.
下面描述对ACK/NACK和SRI联合编码的方法的一个示例。当没有调度请求需要发送时,把ACK/NACK信息映射到ACK/NACK信道,并用第一根天线来发送;同时,把ACK/NACK信息映射到SRI信道,并用第二根天线来发送。当有调度请求需要发送时,把ACK/NACK信息映射到ACK/NACK信道,并用第一根天线来发送;同时,把ACK/NACK信息经变换后映射到SRI信道,并用第二根天线来发送。这里,在直接把ACK/NACK信息映射到ACK/NACK信道或者SRI信道时,对1比特ACK/NACK信息,是进行BPSK调制;对2比特ACK/NACK信息,是进行QPSK调制,例如,表1所示的调制方法,这里,‘1’代表ACK,‘0’代表NACK;然后把BPSK或者QPSK调制符号映射到ACK/NACK信道或者SRI信道。当需要对ACK/NACK信息进行变换然后映射到SRI信道时,对ACK/NACK信息的变换可以是在调制操作之后,即首先对ACK/NACK信息进行调制,例如表1的调制方法;然后对生成的BPSK或者QPSK调制符号进行变换,例如乘以(-1);最后映射到SRI信道。当需要对ACK/NACK信息进行变换然后映射到SRI信道时,对ACK/NACK信息的变换也可以是在调制操作之前,即对ACK/NACK的1比特或者2比特的信息进行变化,这实质上是一种编码操作,然后按照相同的调制方法对每个信道上的信息进行调制,例如,采用表1的调制方法。上面两种方法可以是等效的,表2是采用上述第二种方法表示的发送ACK/NACK和SRI的一种方法。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.
表1:BPSK和QPSK的调制方法Table 1: Modulation methods of BPSK and QPSK
表2:第一种ACK/NACK和SRI联合编码的方法Table 2: The first joint coding method of ACK/NACK and SRI
下面描述对ACK/NACK和SRI联合编码的方法的第二个示例。按照上述第一种方法定义ACK/NACK信道或者SRI信道的物理比特数的方法,采用QPSK的调制方法,每个ACK/NACK信道或者SRI信道能够承载的物理比特数目是2。所以两个信道的物理比特数的总和为4,这样,可以对ACK/NACK和SRI联合编码为4个比特,从而前两个比特映射到ACK/NACK信道,并用第一根天线来发送;后两个比特映射到SRI信道,并用第二根天线来发送。如表3所示是描述了这种联合编码的一种形式。本发明不限制联合编码的具体方法。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.
在表3中,当没有调度请求需要发送时,对1比特ACK/NACK信息重复4次得到4个比特;或者对2比特ACK/NACK,重复2次得到4个比特。在这个例子中,在ACK/NACK信道和SRI信道上发送的信息是相同的。当有调度请求需要发送时,首先,对1比特ACK/NACK信息重复4次得到4个比特;或者对2比特ACK/NACK,重复2次得到4个比特;并对4个比特中的第一个和第四个比特进行取反操作,或者对4个比特中的第二个和第三个比特进行取反操作。在这个例子中,与没有调度请求需要发送时相比,在ACKNACK信道和SRI信道发送的两个比特之一分别进行了取反。这种编码的好处是在接收时,可以使ACK/NACK和SRI都获得天线分集的增益。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.
表3:第二种ACK/NACK和SRI联合编码的方法Table 3: The second ACK/NACK and SRI joint encoding method
下面描述对ACK/NACK和SRI联合编码的方法的第三个示例。按照上述第二种方法定义ACK/NACK信道或者SRI信道的物理比特数的方法,每个ACK/NACK信道或者SRI信道能够承载的物理比特数目是4。所以两个信道的物理比特数的总和为8,这样,可以对ACK/NACK和SRI联合编码为8个比特,从而前4个比特映射到ACK/NACK信道,,并用第一根天线来发送;后4个比特映射到SRI信道,并用第二根天线来发送。本发明不限制联合编码的具体方法。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.

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 .
第一种发送CQI、ACK/NACK和SRI的方法。用户设备对CQI信息和ACK/NACK信息进行联合编码等处理后得到NCQI+NAN个比特。当没有调度请求需要发送时,把NCQI+NAN个比特分为两块,第一个块的比特数是NCQI,第二个块的比特数是NAN;第一个块的比特映射到CQI信道,并用一根天线上来发送;同时,第二个块的比特映射到ACK/NACK信道,并用另一根天线上来发送。注意:当没有调度请求需要发送时,发送CQI和ACK/NACK的方法就是实施例二中的方法。当有调度请求需要发送时,把NCQI+NAN个比特分为两块,这里的分块方法可以与没有调度请求需要发送时的分块方法不同,从而增加SRI检测的可靠性,第一个块的比特数是NCQI,第二个块的比特数是NAN;第一个块的比特映射到CQI信道,并用一根天线上来发送;同时,第二个块的比特映射到SRI信道,并用另一根天线上来发送。以下描述对联合编码输出比特的一种分块方法。当没有调度请求需要发送时,编码输出比特的前NCQI个比特是第一个块,而后NAN个比特是第二个块;当有调度请求需要发送时,编码输出比特的后NCQI个比特是第一个块,而前NAN个比特是第二个块。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.

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.
实施例四:Embodiment four:
假设用户设备需要同时发送CQI和SRI,即基站为用户设备分配了一个CQI信道和一个SRI信道,并假设用户设备配置了两个功率放大器和天线。记CQI信道提供的物理比特数为NCQI,SRI信道提供的物理比特数为NSRI。例如,假设SRI信道包含两个时隙,并且在每个时隙内可以用QPSK调制方法提供2个物理比特,则可以定义每个SRI信道的物理比特数目是NSRI=4。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.
第一种发送方法是用户设备对CQI信息和1比特的SRI信息进行联合编码等处理后,输出NCQI+NSRI比特,然后输出比特分为两块,其中第一个块的比特数是NCQI,第二个块的比特数是NSRI。然后,第一个块的比特映射到CQI信道,并用第一根天线来发送;同时,第二个块的比特映射到SRI信道,并用第二根天线来发送。当需要与实施例三中的把CQI和ACK/NACK联合编码并在CQI信道和SRI信道上发送的情况进行区分时,这里的对NCQI+NSRI输出比特的分块方法可以与实施例三中采用的分块方法不同。例如,假设实施例三中,当有调度请求需要发送时,NCQI+NSRI个编码输出比特的后NCQI个比特是第一个块,而前NSRI个比特是第二个块;那么在本实施例中,可以把NCQI+NSRI个编码输出比特的前NCQI个比特作为第一个块,而后NSRI个比特作为第二个块。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.

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.
