The method comprises: a terminal determining a first numerology according to a first hybrid automatic repeat request (HARQ) process identification (ID) and mapping relationships between HARQ process IDs and numerologies; and the terminal uses a transmission parameter in the first numerology to perform data transmission with a network device. A numerology can be determined by means of an HARQ process ID on the basis of mapping relationships between HARQ process IDs and numerologies, thereby solving a problem in the prior art in which a domain associated with a numerology needs to be added to DCI to indicate the numerology, and accordingly reducing signaling overheads required for indicating a numerology used for data transmission.

Description

数据传输的方法、终端和网络设备Data transmission method, terminal and network device 技术领域Technical field

本申请涉及通信领域，并且更具体地，涉及数据传输的方法、终端和网络设备。The present application relates to the field of communications and, more particularly, to methods, terminals and network devices for data transmission.

背景技术Background technique

在新空口通信系统中，终端和网络设备之间可以使用不同的基础参数集(numerology)传输数据。网络设备需要通过下行控制信息(Downlink Control Information，DCI)向终端指示该终端传输数据使用的基础参数集，即在DCI中增加用于指示基础参数集信息的域，这样，在网络设备进行调度的时候，终端可以通过DCI确定使用哪种基础参数集传输数据。In the new air interface communication system, data can be transmitted between the terminal and the network device using different basic parameter sets (numerology). The network device needs to indicate to the terminal, by using Downlink Control Information (DCI), a basic parameter set used by the terminal to transmit data, that is, a domain for indicating basic parameter set information is added in the DCI, so that the network device performs scheduling. At the time, the terminal can determine which basic parameter set to use to transmit data through the DCI.

然而，上述通过DCI的方式向终端指示传输数据使用的基础参数集的方式，增加了传输DCI的开销。例如，通过DCI指示15KHz，30KHz，60KHz，120KHz的基础参数集，DCI需要增加一个2比特(bit)的域指示不同类型的基础参数集。进一步地，如果基础参数集中包含不同的传输时间间隔(Transmission Time Interval，TTI)，网络设备还需要增加bit数向终端指示该终端传输数据使用基础参数集的哪种TTI。However, the above manner of indicating the basic parameter set used for transmitting data to the terminal by means of DCI increases the overhead of transmitting DCI. For example, by DCI indicating a basic parameter set of 15 KHz, 30 KHz, 60 KHz, and 120 KHz, DCI needs to add a 2-bit field to indicate different types of basic parameter sets. Further, if the basic parameter set includes different Transmission Time Intervals (TTIs), the network device also needs to increase the number of bits to indicate to the terminal which TTI of the basic parameter set used by the terminal to transmit data.

为了便于方案的理解，先介绍本申请实施例中的相关概念。In order to facilitate the understanding of the solution, related concepts in the embodiments of the present application are first introduced.

本申请实施例提到的基础参数集可以包括以下参数中的至少一种：The basic parameter set mentioned in the embodiment of the present application may include at least one of the following parameters:

子载波间隔、特定带宽下的子载波数目、物理资源块PRB中的子载波数、正交频分复用OFDM符号的长度、用于生成OFDM信号的傅里叶变换例如快速傅里叶变换(Fast Fourier Transform，简称“FFT”)或傅里叶逆变换例如快速逆傅里叶变换(Inverse Fast Fourier Transform，简称“IFFT”)的点数、传输时间间隔TTI中的OFDM符号数、特定时间长度内包含的TTI的个数和信号前缀的长度。Subcarrier spacing, number of subcarriers in a particular bandwidth, number of subcarriers in a physical resource block PRB, length of an orthogonal frequency division multiplexed OFDM symbol, Fourier transform for generating an OFDM signal, such as a fast Fourier transform ( Fast Fourier Transform (abbreviated as "FFT") or inverse Fourier transform, such as Inverse Fast Fourier Transform ("IFFT"), the number of OFDM symbols in the transmission time interval TTI, within a certain length of time The number of TTIs included and the length of the signal prefix.

其中，子载波间隔指相邻子载波的频率间隔，例如15kHz，60kHz等；特定带宽下的子载波数目例如为每个可能的系统带宽对应的子载波数；PRB中包含的子载波数，例如典型的可以是12的整数倍；TTI中包含的OFDM符号数，例如典型的可以是14的整数倍；一定时间单位内包含的TTI数可以指5 1ms或者10ms的时间长度内包含的TTI数目；信号前缀长度例如信号的循环前缀的时间长度，或者循环前缀使用常规CP还是使用扩展CP。The subcarrier spacing refers to the frequency interval of adjacent subcarriers, for example, 15 kHz, 60 kHz, etc.; the number of subcarriers in a specific bandwidth is, for example, the number of subcarriers corresponding to each possible system bandwidth; the number of subcarriers included in the PRB, for example, Typically, it may be an integer multiple of 12; the number of OFDM symbols included in the TTI, for example, may be an integer multiple of 14; the number of TTIs included in a certain time unit may refer to the number of TTIs included in the length of 5 1 ms or 10 ms; The signal prefix length is, for example, the length of the cyclic prefix of the signal, or whether the cyclic prefix uses a regular CP or an extended CP.

在NR标准化讨论中，终端和网络设备之间可以使用不同类型的基础参数集传输数据。可以在相同的载波或不同的载波上使用不同的基础参数集传输数据。一般来说，不同的基础参数集可以通过子载波间隔来区分，比如可以把对应15KHz的基础参数集作为参考基础参数集。例如，其他类型的基础参数集中子载波间隔可取值为15KHz×2n，n为非负整数；其他类型的基础参数集中一个子帧包含的时隙(slots)数量可以为参考基础参数集中时隙 数的2n，n为非负整数；其他类型的基础参数集中一个资源块RB在频域上可以与参考基础参数集在频域上包含的子载波数相同(例如，12个)。当n＝1时，基础参数集中的子载波间隔为30KHz，一个子帧可以包含的时隙数量为4个。In the NR standardization discussion, data can be transmitted between terminals and network devices using different types of basic parameter sets. Data can be transmitted using different base parameter sets on the same carrier or on different carriers. In general, different basic parameter sets can be distinguished by subcarrier spacing. For example, a basic parameter set corresponding to 15 KHz can be used as a reference basic parameter set. For example, the subcarrier spacing of other types of basic parameter sets may be 15 KHz×2 n , and n is a non-negative integer; the number of slots included in one subframe of other types of basic parameter sets may be the reference base parameter concentration. The number of slots is 2 n , n is a non-negative integer; in the other types of basic parameter sets, one resource block RB may be the same in the frequency domain as the reference base parameter set in the frequency domain (for example, 12). When n=1, the subcarrier spacing in the basic parameter set is 30KHz, and the number of slots that one subframe can contain is four.

目前讨论的在同一个载波中复用不同类型的基础参数集，主要有如下两种复用方式：Currently discussed in the same carrier to multiplex different types of basic parameter sets, there are two main ways of multiplexing:

1、时分复用(Time Division Multiplexing，TDM)，也就是说，在相同的带宽内，不同的基础参数集可以在时域上进行复用。应理解，不同的基础参数集对应的时间段可以相同也可以不同。参见图2，3种不同类型的基础参数集在相同的带宽内包含的子载波数量不同。假设每个RB分别对应12个子载波，则在相同带宽内，第一基础参数集中包含的子载波数量为48个，第二基础参数集中包含的子载波数量为24个，第三基础参数集中包含的子载波数量为12个。1. Time Division Multiplexing (TDM), that is, different basic parameter sets can be multiplexed in the time domain within the same bandwidth. It should be understood that the time periods corresponding to different basic parameter sets may be the same or different. Referring to Figure 2, the three different types of basic parameter sets contain different numbers of subcarriers in the same bandwidth. Assuming that each RB corresponds to 12 subcarriers, the number of subcarriers included in the first basic parameter set is 48, and the number of subcarriers included in the second basic parameter set is 24, and the third basic parameter set includes The number of subcarriers is 12.

2、频分复用(Frequency Division Multiplexing，FDM)，也就是说，在相同的时间间隔内，不同的基础参数集可以在频域上进行复用。应理解，不同的基础参数集对应的带宽可以相同也可以不同。每个RB可以对应1个时隙，参见图3，3种不同类型的基础参数集在相同的时间间隔内包含的时隙数量不同。例如，第一基础参数集在该传输时间间隔内包含1个时隙，第二基础参数集在该传输时间间隔内包含2个时隙，第三基础参数集在该传输时间间隔内包含4个时隙。2. Frequency Division Multiplexing (FDM), that is, different basic parameter sets can be multiplexed in the frequency domain in the same time interval. It should be understood that the bandwidths corresponding to different basic parameter sets may be the same or different. Each RB can correspond to 1 time slot. Referring to Figure 3, the three different types of basic parameter sets contain different numbers of time slots in the same time interval. For example, the first basic parameter set includes 1 time slot in the transmission time interval, the second basic parameter set includes 2 time slots in the transmission time interval, and the third basic parameter set includes 4 in the transmission time interval. Time slot.

由于在相同的载波或不同的载波上使用不同的基础参数集传输数据，终端在传输数据的时候需要确定使用哪种基础参数集传输数据，网络设备需要通过DCI向终端指示该终端传输数据使用的基础参数集。然而，这种通过DCI的方式向终端指示传输数据使用的基础参数集的方式，增加了传输DCI的开销。为了减小传输DCI的开销，下面结合图4详细描述本申请实施例的数据传输的方法。Since data is transmitted using different basic parameter sets on the same carrier or different carriers, the terminal needs to determine which basic parameter set to use to transmit data when transmitting data, and the network device needs to indicate to the terminal through the DCI that the terminal transmits data. The base parameter set. However, this way of indicating the basic parameter set used for transmitting data to the terminal by means of DCI increases the overhead of transmitting DCI. In order to reduce the overhead of transmitting DCI, the method of data transmission in the embodiment of the present application is described in detail below with reference to FIG.

图4是本申请实施例的数据传输的方法的示意性流程图。图4所示的方法包括：FIG. 4 is a schematic flowchart of a method for data transmission in an embodiment of the present application. The method shown in Figure 4 includes:

需要说明的是，上述HARQ进程ID与基础参数集的映射关系可以指HARQ进程ID与基础参数集的标识之间的映射关系，还可以指HARQ进程ID与基础参数集中传输参数的直接对应关系，本申请实施例对此不作具体限定。It should be noted that the mapping relationship between the foregoing HARQ process ID and the basic parameter set may refer to a mapping relationship between the HARQ process ID and the identifier of the basic parameter set, and may also refer to a direct correspondence between the HARQ process ID and the transmission parameters of the basic parameter set. This embodiment of the present application does not specifically limit this.

还应理解，上述基础参数集的标识可以使用基础参数集中的任意一个或几个传输参数进行标识。例如，基础参数集可以使用该基础参数集中的TTI进行标识，基础参数集还可以使用该基础参数集中的子载波间隔进行标识，本申请实施例It should also be understood that the identification of the above basic parameter set can be identified using any one or several transmission parameters in the base parameter set. For example, the basic parameter set may be identified by using the TTI in the basic parameter set, and the basic parameter set may also be identified by using the subcarrier spacing in the basic parameter set.

具体地，上述HARQ进程ID与基础参数集的映射关系中，HARQ进程ID与基础参数集可以为一一对应的关系。也就是说，一个HARQ进程ID对应一类基础参数集。Specifically, in the mapping relationship between the foregoing HARQ process ID and the basic parameter set, the HARQ process ID and the basic parameter set may have a one-to-one correspondence. That is to say, one HARQ process ID corresponds to a basic parameter set.

例如，表1所示的HARQ进程ID与基础参数集的对应关系中，每个HARQ进程ID可以对应一个基础参数集，其中该基础参数集可以以该基础参数集中的TTI为标识。For example, in the correspondence between the HARQ process ID and the basic parameter set shown in Table 1, each HARQ process ID may correspond to a basic parameter set, where the basic parameter set may be identified by a TTI in the basic parameter set.

表1Table 1

具体地，上述多个HARQ进程ID中的至少部分HARQ进程ID中的每个HARQ进程ID对应集合，可以指多个HARQ进程ID中的每个HARQ进程ID都对应一个集合，还可以指多个HARQ进程ID中的一部分HARQ进程ID中的每个HARQ进程ID对应一个集合。Specifically, each HARQ process ID corresponding to the at least part of the multiple HARQ process IDs may be a set, and may refer to each of the multiple HARQ process IDs, and may also refer to multiple Each of the HARQ process IDs in the HARQ process ID corresponds to one set.

例如，表2所示的HARQ进程ID与基础参数集的对应关系中，其中，HARQ进程ID 0和HARQ进程ID 4分别对应一个集合，该集合中包含多个 基础参数集。For example, in the correspondence between the HARQ process ID and the basic parameter set shown in Table 2, the HARQ process ID 0 and the HARQ process ID 4 respectively correspond to one set, and the set includes multiple The base parameter set.

需要说明的是，一个基础参数集可以指该基础参数集中的每类传输参数都只有一个取值。上述集合中包含多个基础参数集，可以指该集合中包含的多个基础参数集中至少部分的传输参数的取值不同。It should be noted that a basic parameter set may mean that each type of transmission parameter in the basic parameter set has only one value. The foregoing set includes a plurality of basic parameter sets, which may be different values of at least part of the transmission parameters of the plurality of basic parameter sets included in the set.

可选地，所述映射关系中的多个HARQ进程ID为预设的HARQ进程ID中的至少部分HARQ进程ID。Optionally, the multiple HARQ process IDs in the mapping relationship are at least part of the HARQ process IDs in the preset HARQ process ID.

For example, the HARQ process ID preset based on the communication protocol may be 0 to 7, but the HARQ process ID in the above correspondence may be 0 to 3.

需要说明的是，上述第一基础参数集的索引可以和网络设备向终端发送的HARQ进程ID的信息为相同的信息，也就是说，网络设备可以通过一条信息向终端指示HARQ进程ID和第一基础参数集的索引；网络设备也可以分别向终端发送两条指示信息，分别用于指示HARQ进程ID和第一基础参数集的索引。It should be noted that the index of the first basic parameter set may be the same information as the information of the HARQ process ID sent by the network device to the terminal, that is, the network device may indicate the HARQ process ID and the first to the terminal by using one piece of information.
