背景技术Background technique
随着物联网业务的不断发展，例如视频监控，智能家居，可穿戴设备和工业传感监测等业务的普及，这些业务通常要求几十到100M的数据传输速率，同时对时延也有相对较高的要求，而传统LTE***中的相关技术难以满足其需求。基于该情况，提出了在5G新空口中再设计一种新的用户设备，在目前的3GPP标准化中，这种新的终端类型叫做降低能力的终端(Reduced capability UE，Redcap UE)。在RedCap技术中，降低了最大带宽到20MHz，从而降低了射频前段滤波器的要求，并且也降低了基带处理能力的要求。With the continuous development of IoT services, such as the popularity of video surveillance, smart home, wearable devices and industrial sensor monitoring, these services usually require data transmission rates of tens to 100M, and also have relatively high latency requirements. requirements, and the related technologies in traditional LTE systems are difficult to meet their needs. Based on this situation, it is proposed to design a new user equipment in the 5G new air interface. In the current 3GPP standardization, this new terminal type is called reduced capability UE (Redcap UE). In RedCap technology, the maximum bandwidth is reduced to 20MHz, thereby reducing the requirements for RF front-end filters and also reducing the requirements for baseband processing capabilities.
相关技术中，针对RedCap技术中带宽减少的处理方案，可能会影响公共数据信道的覆盖能力，降低公共数据信道的数据传输质量。In related technologies, solutions for bandwidth reduction in RedCap technology may affect the coverage capability of public data channels and reduce the data transmission quality of public data channels.

举例而言，针对上述信道发送方法和信道接收方法，可以举例说明如下：For example, the above channel sending method and channel receiving method can be described as follows:
(1)一种针对第一类型终端的公共数据信道的传输方案，支持公共数据信道在时域上进行重复传输。(1) A transmission scheme for a public data channel for a first type of terminal, supporting repeated transmission of the public data channel in the time domain.
(2)基于(1)，公共数据信道在时域上重复发送的次数基于控制信道DCI进行指示。(2) Based on (1), the number of times the common data channel is repeatedly transmitted in the time domain is indicated based on the control channel DCI.
(3)基于(2)，在DCI中定义独立的指示域对重复发送次数进行指示。具体的，协议预定义重复发送次数集合，DCI指示这个集合中的一个元素。(3) Based on (2), define an independent indication field in DCI to indicate the number of repeated transmissions. Specifically, the protocol predefines a set of repeated transmission times, and DCI indicates an element in this set.
(4)基于(2)，将重复发送次数与默认时域资源分配表中的信息进行联合编码形成新的默认时域资源分配表。具体的，可以在默认时域资源分配表中加入重复发送次数的信息。在DCI中定义独立的指示域对行索引Row index进行指示。如下是一个例子。(4) Based on (2), the number of repeated transmissions and the information in the default time domain resource allocation table are jointly encoded to form a new default time domain resource allocation table. Specifically, information about the number of repeated transmissions can be added to the default time domain resource allocation table. Define an independent indication field in the DCI to indicate the row index. Below is an example.
(5)基于(4)，表3可以如下所示：(5) Based on (4), Table 3 can be as follows:
Figure PCTCN2022111920-appb-000005

Figure PCTCN2022111920-appb-000006
Figure PCTCN2022111920-appb-000006
可以理解的是，表3中的每一个元素都是独立存在的，这些元素被示例性的列在同一张表格中，但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值，是不依赖于表3中任何其他元素值。因此本领域内技术人员可以理解，该表3中的每一个元素的取值都是一个独立的实施例。It can be understood that each element in Table 3 exists independently, and these elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time as shown in the table. The value of each element is not dependent on the value of any other element in Table 3. Therefore, those skilled in the art can understand that the value of each element in Table 3 is an independent embodiment.
(6)基于(4)，针对不同的公共数据信道时域持续OFDM符号数，所对应支持的重复发送次数不同。(6) Based on (4), for different numbers of sustained OFDM symbols in the time domain of the public data channel, the corresponding number of repeated transmissions supported is different.
(7)基于(4)，相比于原来的默认时域资源分配表，针对第一终端类型设计的第一默认时域资源分配表，所支持的多个候选分配参数中，至少两个参数的组合变少了。例如原来表格中下行数据信道的第一起始OFDM符号和下行数据信道占用的第一OFDM符号个数的组合方案共有16种，但在如下表4所示，只有7种下行数据信道的第一起始OFDM符号和下行数据信道占用的第一OFDM符号个数的组合方案。(7) Based on (4), compared with the original default time domain resource allocation table, the first default time domain resource allocation table designed for the first terminal type supports at least two parameters among the multiple candidate allocation parameters. There are fewer combinations. For example, in the original table, there are 16 combinations of the first starting OFDM symbol of the downlink data channel and the number of first OFDM symbols occupied by the downlink data channel. However, as shown in Table 4 below, there are only 7 kinds of first starting OFDM symbols of the downlink data channel. The combination scheme of the number of OFDM symbols and the first OFDM symbols occupied by the downlink data channel.

可以理解的是，表4中的每一个元素都是独立存在的，这些元素被示例性的列在同一张表格中，但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值，是不依赖于表4中任何其他元素值。因此本领域内技术人员可以理解，该表4中的每一个元素的取值都是一个独立的实施例。It can be understood that each element in Table 4 exists independently. These elements are exemplarily listed in the same table, but this does not mean that all elements in the table must exist at the same time as shown in the table.
