具体实施方式Detailed ways

目前，针对不同的双工方式设计了不同的通信方式，例如，对于FDD来说，网络设备为终端设备分别配置上行频域资源和下行频域资源，为配对的频谱(paired spectrum)，终端设备可以同时在上行频域资源和下行频域资源上传输数据，而无需指示时域资源传输状态，具体的时域资源传输状态指的是在时域资源上传输上行数据还是下行数据，亦或是不传输数据如用于上下行切换等，在这种情况下终端设备将上行频域资源或者下行频域资源不用于传输数据的时域资源作为未知时域资源；对于TDD来说，网络设备为终端设备分配频域资源，为不配对的频谱(unpaired spectrum)，其中该频域资源既可以用来传输上行数据，也可以用于传输下行数据，具体传输上行数据还是下行数据、或者不传输数据等与时域资源上的传输状态有关，具体的，TDD中通过如表1所示的上下行配置表来指示时域资源上的传输状态，其中D表示子帧用于传输下行数据、U表示子帧用于传输上行数据、S表示特殊子帧。At present, different communication modes are designed for different duplex modes. For example, for FDD, the network device configures the uplink frequency domain resource and the downlink frequency domain resource for the terminal device respectively, which is a paired spectrum (paired spectrum), and the terminal device Data can be transmitted on both the uplink frequency domain resource and the downlink frequency domain resource without indicating the time domain resource transmission state. The specific time domain resource transmission state refers to whether the uplink data or the downlink data is transmitted on the time domain resource, or The data is not transmitted, such as for uplink and downlink handover. In this case, the terminal device uses the uplink frequency domain resource or the time domain resource whose downlink frequency domain resource is not used for transmitting data as the unknown time domain resource. For TDD, the network device is The terminal device allocates a frequency domain resource, which is an unpaired spectrum, wherein the frequency domain resource can be used for transmitting uplink data or for transmitting downlink data, and specifically transmitting uplink data or downlink data, or not transmitting data. It is related to the transmission status on the time domain resource. Specifically, the TDD passes the uplink and downlink configuration as shown in Table 1. Table indicating a transmission status on a time domain resource, where D denotes the subframe used for downlink data transmission, U denotes the subframe used for uplink transmission of data, S denotes a special subframe.

表1Table 1

以表1中的上下行配置索引为4为例，则终端设备可以在网络设备分配的频域资源上，在第0子帧接收下行数据，在第2子帧发送上行数据，在第1子帧上进行上下行的切换，在TDD中终端设备根据网络设备指示的上下行配置索引来确定特殊子帧，其中特殊子帧中的保护时间间隔(Guard Period，GP)可等效于未知时域资源的一种用途。Taking the uplink and downlink configuration index of Table 1 as an example, the terminal device can receive downlink data in the 0th subframe and transmit uplink data in the 2nd subframe on the frequency domain resource allocated by the network device, in the first sub-subframe. The uplink and downlink are switched on the frame. In the TDD, the terminal device determines the special subframe according to the uplink and downlink configuration index indicated by the network device, where the guard interval (GP) in the special subframe may be equivalent to the unknown time domain. A use of resources.

因而不同的双工方式下，网络设备为终端设备配置的频域资源的方式是不同的，导致终端设备确定未知时域资源的方式是不同的，当终端设备和网络设备既支持TDD又支持FDD时，通常情况下，为了使得终端设备和网络设备之间能够正常通信，网络设备通过向终端设备发送额外的指示信息来使得终端设备确定采用哪种双工方式进行通信，从而使得终端设备在确定的相应双工方式下来进一步确定时域资源上的未知时域资源，进而实现网络设备和终端设备之间的数据传输，但是上述技术方案增加了信令的开销和网络设备配置的复杂度。Therefore, in different duplex modes, the manner in which the network device configures the frequency domain resources for the terminal device is different, and the manner in which the terminal device determines the unknown time domain resources is different. When the terminal device and the network device support both TDD and FDD, In general, in order to enable normal communication between the terminal device and the network device, the network device causes the terminal device to determine which duplex mode to use for communication by transmitting additional indication information to the terminal device, thereby causing the terminal device to determine The corresponding duplex mode further determines the unknown time domain resource on the time domain resource, thereby implementing data transmission between the network device and the terminal device, but the above technical solution increases the signaling overhead and the complexity of the network device configuration.

为了解决上述技术问题，本申请实施例提出了一种确定时域资源的方法，使得终端设备能够根据指示信息和频域资源配置信息来确定未知频域资源，其中指示信息用于指示时隙的格式，与上述技术方案相比，无需增加额外的信令来指示终端设备所采用的双工方式，有助于降低信令的开销和网络设备配置的复杂度。In order to solve the above technical problem, the embodiment of the present application provides a method for determining a time domain resource, so that the terminal device can determine an unknown frequency domain resource according to the indication information and the frequency domain resource configuration information, where the indication information is used to indicate a time slot. The format, compared with the above technical solution, does not need to add additional signaling to indicate the duplex mode adopted by the terminal device, which helps to reduce the signaling overhead and the complexity of the network device configuration.

The number of downlink symbols is an example. The correspondence table between the index number and the format of the time slot can be as shown in Table 2.

作为一个实例，上行符号的位置和下行符号的位置的确定规则可以预先配置为下行符号的位置从时隙中第一个符号位置开始向后连续数N1个，上行符号的位置从该时隙中最后一个符号的位置开始向前连续数N2个，其中N1为时隙的格式中包括的下行符号的个数， N1为时隙的格式中包括的上行符号的个数。在上行符号的位置和下行符号的位置的确定规则可以预先配置为上述规则的情况下，若一个时隙包括14个符号，当指示信息为索引号1时，时隙的格式如图3a所示，前12个符号为下行符号，第14个符号为上行符号。As an example, the determining rule of the position of the uplink symbol and the position of the downlink symbol may be pre-configured such that the position of the downlink symbol is consecutively N1 consecutively from the first symbol position in the slot, and the position of the uplink symbol is from the slot. The position of the last symbol starts to advance by a number of N2, where N1 is the number of downlink symbols included in the format of the slot, and N1 is the number of uplink symbols included in the format of the slot.

The position of the next symbol of the position starts to be consecutively N2, where N1 is the number of downlink symbols included in the format of the slot, and N1 is the number of uplink symbols included in the format of the slot.

If a time slot includes 14 symbols, when the indication information is index number 1, the format of the time slot is as shown in FIG. 3b. The first 12 symbols are the down symbols and the 13th symbols are the up symbols.

在一个实施例，上行符号的位置和下行符号的位置的确定规则还可以预先配置为下行符号的位置从时隙中第一个符号位置开始向后连续数N1个，上行符号的起始位置与下行符号结束位置间隔一个符号，其中N1为时隙的格式中包括的下行符号的个数，N1为时隙的格式中包括的上行符号的个数。在上行符号的位置和下行符号的位置的确定规则可以预先配置为上述规则的情况下，若一个时隙包括14个符号，当指示信息为索引号1时，时隙的格式如图3a所示，前12个符号为下行符号，第14个符号为上行符号，其中下行符号的结束位置与上行符号的起始位置间隔一个符号。In an embodiment, the determining rule of the position of the uplink symbol and the position of the downlink symbol may also be pre-configured such that the position of the downlink symbol is consecutively N1 consecutively from the first symbol position in the slot, and the starting position of the uplink symbol is The downlink symbol end position is separated by one symbol, where N1 is the number of downlink symbols included in the format of the slot, and N1 is the number of uplink symbols included in the format of the slot. In the case where the determination rule of the position of the uplink symbol and the position of the downlink symbol can be pre-configured as the above rule, if one slot includes 14 symbols, when the indication information is index number 1, the format of the slot is as shown in FIG. 3a. The first 12 symbols are downlink symbols, and the 14th symbol is an uplink symbol, wherein the end position of the downlink symbol is separated from the start position of the uplink symbol by one symbol.

此外，索引号与时隙的格式的对应关系表还可以如表3所示，其中时隙的格式包括上行符号的个数、下行符号的个数和unknown符号的个数。In addition, the correspondence table between the index number and the format of the time slot may also be as shown in Table 3.

其中当索引号与时隙格式的对应关系表为表3时，其上行符号的位置和下行符号的位置的确定规则的配置方式与表2中上行符号的位置和下行符号的位置的确定规则的配置方式类似，在此不再赘述。Wherein, when the correspondence table between the index number and the slot format is Table 3, the setting manner of the determining rule of the position of the uplink symbol and the position of the downlink symbol and the determining rule of the position of the uplink symbol and the position of the downlink symbol in Table 2 The configuration is similar, and will not be described here.

此外，索引号与时隙的格式的对应关系表还可以如表4所示，其中时隙的格式包括上行符号的个数、下行符号的个数和unknown符号的个数。In addition, the correspondence table between the index number and the format of the time slot may also be as shown in Table 4, wherein the format of the time slot includes the number of uplink symbols, the number of downlink symbols, and the number of unknown symbols.

表4Table 4

其中当索引号与时隙格式的对应关系表为表4时，其上行符号的位置和下行符号的位置的确定规则的配置方式与表2中上行符号的位置和下行符号的位置的确定规则的配置方式类似，在此不再赘述。Wherein, when the correspondence table between the index number and the slot format is Table 4, the setting manner of the determining rule of the position of the uplink symbol and the position of the downlink symbol and the determining rule of the position of the uplink symbol and the position of the downlink symbol in Table 2 The configuration is similar, and will not be described here.

表5table 5

示例的，索引号1对应的时隙的格式中第0个到第11个位置为下行符号，第13个位置为上行符号。For example, the 0th to the 11th positions in the format of the slot corresponding to the index number 1 are downlink symbols, and the 13th position is an uplink symbol.

应理解，当时隙的格式包括unknown符号的个数、或者时隙的格式包括unknown符号的位置、或者时隙的格式包括unknown符号的个数和位置、或者时隙的格式包括上行符号的位置和下行符号的位置时等，具体实现方式与时隙的格式包括上行符号的个数和下行符号的个数类似，在此不再赘述。It should be understood that when the format of the time slot includes the number of unknown symbols, or the format of the time slot includes the location of the unknown symbol, or the format of the time slot includes the number and location of the unknown symbol, or the format of the time slot includes the position of the uplink symbol and The format of the downlink symbol is the same as that of the downlink symbol, and the format of the slot is similar to the number of the downlink symbol, and is not described here.

步骤202，终端设备根据指示信息和频域资源配置信息，确定时隙中unknown时域资源。Step 202: The terminal device determines, according to the indication information and the frequency domain resource configuration information, the unknown time domain resource in the time slot.

其中，频域资源配置信息可以为网络设备发送给终端设备，在具体实现时，网络设备可以通过高层信令，如RRC信令等发送给终端设备。The frequency domain resource configuration information may be sent to the terminal device for the network device. In specific implementation, the network device may send the device to the terminal device by using high layer signaling, such as RRC signaling.

作为一个示例，在频域资源配置信息指示上行频域资源的中心频点和下行频域资源的中心频点重合时，终端设备确定unknown时域资源为时隙中除上行符号和下行符号以外的符号。As an example, when the frequency domain resource configuration information indicates that the center frequency of the uplink frequency domain resource and the center frequency of the downlink frequency domain resource coincide, the terminal device determines that the unknown time domain resource is other than the uplink symbol and the downlink symbol in the time slot. symbol.

可选的，频域资源配置信息可以直接指示上行频域资源的中心频点和下行频域资源的中心频点重合，或者，频域资源配置信息包括网络设备为终端设备配置频域资源时的配置参数，如SCS、带宽参数(如上行频域资源的带宽和下行频域资源的带宽)、频域位置参数等，终端设备可以根据这些参数来确定频域资源配置信息指示上行频域资源的中心频点和下行频域资源的中心频点重合。具体的，以频域资源为BWP为例，如图4所示，终端设备可以根据上行BWP的频域位置参数确定上行BWP的最低频率位置f1，根据上行BWP的带宽参数结合上行BWP的SCS可以获得上行BWP的绝对带宽值BW1，然后确定上行BWP的中心频率为(f1+BW1/2)；终端设备基于同样的方式确定下行BWP的中心频率为(f2+BW2/2)，其中f2为下行BWP的最低频率位置，BW2为下行BWP的绝对带宽值。若(f1+BW1/2)＝(f2+BW2/2)，则上行BWP的中心频率和下行BWP的中心频率重合。Optionally, the frequency domain resource configuration information may directly indicate that the center frequency of the uplink frequency domain resource and the center frequency of the downlink frequency domain resource overlap, or the frequency domain resource configuration information includes when the network device configures the frequency domain resource for the terminal device. The configuration parameter, such as the SCS, the bandwidth parameter (such as the bandwidth of the uplink frequency domain resource and the bandwidth of the downlink frequency domain resource), the frequency domain location parameter, etc., the terminal device may determine, according to the parameters, the frequency domain resource configuration information, indicating the uplink frequency domain resource. The center frequency of the center frequency and the downlink frequency domain coincide. Specifically, the frequency domain resource is used as the BWP. As shown in FIG. 4, the terminal device can determine the lowest frequency position f1 of the uplink BWP according to the frequency domain location parameter of the uplink BWP, and combine the bandwidth parameter of the uplink BWP with the SCS of the uplink BWP. Obtain an absolute bandwidth value BW1 of the uplink BWP, and then determine that the center frequency of the uplink BWP is (f1+BW1/2); the terminal device determines, according to the same manner, that the center frequency of the downlink BWP is (f2+BW2/2), where f2 is the downlink. The lowest frequency position of the BWP, and BW2 is the absolute bandwidth value of the downlink BWP. If (f1+BW1/2)=(f2+BW2/2), the center frequency of the uplink BWP coincides with the center frequency of the downlink BWP.

应理解，在上行频域资源的中心频率和下行频域资源的中心频域重合时，网络设备为终端设备配置的频域资源为unpaired spectrum。可选的，终端设备还可以确定unknown频域资源为上行频域资源和下行频域资源中带宽较大的频域资源。It should be understood that when the center frequency of the uplink frequency domain resource and the central frequency domain of the downlink frequency domain resource overlap, the frequency domain resource configured by the network device for the terminal device is an unpaired spectrum. Optionally, the terminal device may further determine that the unknown frequency domain resource is a frequency domain resource with a larger bandwidth in the uplink frequency domain resource and the downlink frequency domain resource.

以指示信息为表2中的索引号1为例，由于索引号1对应下行符号个数为12个，上行符号个数为1个，示例的，假设时隙的格式如图3a所示，若下行频域资源的带宽大于上行频域资源的带宽，则unknown频域资源为下行频域资源，进一步的，unknown时频资源可以如图5a所示，包括由第13个符号和下行频域资源所组成的时频资源。Taking the index number 1 in Table 2 as an example, the index number 1 corresponds to 12 downlink symbols and the number of uplink symbols is 1. For example, the format of the slot is as shown in FIG. 3a. If the bandwidth of the downlink frequency domain resource is greater than the bandwidth of the uplink frequency domain resource, the unknown frequency domain resource is the downlink frequency domain resource. Further, the unknown time-frequency resource may be as shown in FIG. 5a, including the 13th symbol and the downlink frequency domain resource. The time-frequency resources that are composed.

此外，本申请实施例中unknown时频资源可以如图5b所示的阴影区域，包括由第13个符号和下行频域资源组成的时频资源，以及由第14个符号和其它频域资源组成的时频资源，其中其它频域资源为下行频域资源中除去上行频域资源的部分频域资源。在这种情况下，unknown时域资源为第13个符号和第14个符号，unknown频域资源为下行频域资源和其它频域资源。In addition, the unknown time-frequency resource in the embodiment of the present application may be a shaded area as shown in FIG. 5b, including a time-frequency resource composed of a thirteenth symbol and a downlink frequency domain resource, and composed of a 14th symbol and other frequency domain resources. The time-frequency resource, wherein the other frequency domain resources are part of the frequency domain resources of the downlink frequency domain resource except the uplink frequency domain resource. In this case, the unknown time domain resource is the 13th symbol and the 14th symbol, and the unknown frequency domain resource is the downlink frequency domain resource and other frequency domain resources.

应理解，当下行频域资源的带宽和上行频域资源的带宽相等时，unknown频域资源可以为上行频域资源，也可以为下行频域资源。It should be understood that when the bandwidth of the downlink frequency domain resource and the bandwidth of the uplink frequency domain resource are equal, the unknown frequency domain resource may be an uplink frequency domain resource or a downlink frequency domain resource.

作为另一个示例，在频域资源配置信息指示上行频域资源的中心频点和下行频域资源的中心频点不重合时，终端设备确定unknown时域资源为时隙中除上行符号以外的符号和时隙中除下行符号以外的符号取并集后获得的符号。以图3a所示的时隙的格式为例，时隙中除上行符号以外的符号为第1个符号至第13个符号,时隙中除下行符号以外的符号为第13和14个符号。As another example, when the frequency domain resource configuration information indicates that the center frequency point of the uplink frequency domain resource and the center frequency point of the downlink frequency domain resource do not coincide, the terminal device determines that the unknown time domain resource is a symbol other than the uplink symbol in the time slot. A symbol obtained after taking a union of symbols other than the down symbol in the slot. Taking the format of the slot shown in FIG. 3a as an example, symbols other than the uplink symbol in the slot are the first symbol to the thirteenth symbol, and symbols other than the downlink symbol in the slot are the 13th and 14th symbols.

需要说明的是，本申请实施例中频域资源配置信息指示上行频域资源的中心频点和下行频域资源的中心频点不重合的方式与频域资源配置信息指示上行频域资源的中心频点和下行频域资源的中心频点重合的方式类似，在此不再赘述。应理解，在上行频域资源的中心频点和下行频域资源的中心频点不重合时，以图4为例，则(f1+BW1/2)≠(f2+BW2/2)。It should be noted that, in the embodiment of the present application, the frequency domain resource configuration information indicates that the center frequency point of the uplink frequency domain resource and the center frequency point of the downlink frequency domain resource do not overlap, and the frequency domain resource configuration information indicates the center frequency of the uplink frequency domain resource. The manner in which the center frequency of the point and the downlink frequency domain resources coincide is similar, and will not be described here. It should be understood that when the center frequency of the uplink frequency domain resource and the center frequency of the downlink frequency domain resource do not overlap, as shown in FIG. 4, (f1+BW1/2)≠(f2+BW2/2).

应理解，在上行频域资源的中心频率和下行频域资源的中心频域不重合时，网络设备为终端设备配置的频域资源为配对的频谱(paired spectrum)。可选的，终端设备确定unknown频域资源包括时隙中除上行符号以外的符号对应的所述上行频域资源和/或时隙中除下行符号以外的符号对应的所述下行频域资源。It should be understood that when the center frequency of the uplink frequency domain resource and the central frequency domain of the downlink frequency domain resource do not coincide, the frequency domain resource configured by the network device for the terminal device is a paired spectrum. Optionally, the terminal device determines that the unknown frequency domain resource includes the downlink frequency domain resource corresponding to the symbol other than the uplink symbol in the time slot, and/or the downlink frequency domain resource corresponding to the symbol except the downlink symbol in the time slot.

在具体实现时，当时隙中除上行符号和下行符号以外的符号为unknown时域资源时，终端设备确定unknown频域资源为上行频域资源和下行频域资源的并集获得的频域资源；当时隙中上行符号为unknown时域资源时，终端设备确定unknown频域资源为下行频域资源；当时隙中下行符号为unknown频域资源时，终端设备确定unknown频域资源为上行频域资源。In a specific implementation, when the symbols in the time slot except the uplink symbol and the downlink symbol are unknown time domain resources, the terminal device determines that the unknown frequency domain resource is a frequency domain resource obtained by combining the uplink frequency domain resource and the downlink frequency domain resource; When the uplink symbol in the time slot is the unknown time domain resource, the terminal device determines that the unknown frequency domain resource is the downlink frequency domain resource. When the downlink symbol in the time slot is the unknown frequency domain resource, the terminal device determines that the unknown frequency domain resource is the uplink frequency domain resource.

示例的，以表2中索引号为1时对应的时隙的格式为例，若索引号为1时对应的时隙的格式如图3a所示，在上行频域资源和下行频域资源为paired spectrum的情况下，对于第1个符号到第12个符号为unknown时频资源的情况下，上行频域资源为unknown频域资源；而对于第1个符号到第12个符号为下行符号的情况下，下行频域资源用于传输下行数据；第13个符号既不是上行符号又不是下行符号，因此，对于第13个符号为unknown时频资源的情况下，上行频域资源和下行频域资源的并集获得的频域资源为unknown频域资源；对于第14个符号为unknown时频资源的情况下，下行频域资源为unknown频域资源；而对于第14个符号为上行符号的情况下，上行频域资源用于传输上行数据。其中，在时隙的格式如图3a所示的情况下，unknown时频资源可以如图6所示的阴影区域，包括由时隙中第13、14个符号和下行频域资源组成的时频资源、以及由时隙中第1个符号至第13个符号、和上行频域资源组成的时频资源。For example, the format of the corresponding time slot in the index number 1 in Table 2 is taken as an example. If the index number is 1, the format of the corresponding time slot is as shown in FIG. 3a, and the uplink frequency domain resource and the downlink frequency domain resource are In the case of the paired spectrum, in the case where the first symbol to the twelfth symbol are unknown time-frequency resources, the uplink frequency domain resource is an unknown frequency domain resource; and for the first symbol to the twelfth symbol is a downlink symbol. In the case that the downlink frequency domain resource is used for transmitting downlink data, the 13th symbol is neither an uplink symbol nor a downlink symbol. Therefore, when the 13th symbol is an unknown time-frequency resource, the uplink frequency domain resource and the downlink frequency domain are used. The frequency domain resource obtained by the union of resources is unknown frequency domain resource; when the 14th symbol is unknown time-frequency resource, the downlink frequency domain resource is unknown frequency domain resource; and for the 14th symbol is the uplink symbol The uplink frequency domain resource is used to transmit uplink data. Wherein, in the case of the format of the time slot as shown in FIG. 3a, the unknown time-frequency resource may be a shadow area as shown in FIG. 6, including a time frequency composed of the 13th and 14th symbols in the time slot and the downlink frequency domain resources. A resource, and a time-frequency resource consisting of a first symbol to a thirteenth symbol in the time slot and an uplink frequency domain resource.

还需要说明的是，本申请实施例中在索引号与时隙的格式的对应关系如表2所示时，网络设备不管为终端设备配置的上行频域资源和下行频域资源为paired spectrum还是unpaired spectrum的情况下，均可以从表2中选择任意一个索引号，指示给终端设备，终端设备在接收到网络设备发送的索引号后，根据索引号和频域资源配置信息再进一步确定unknown时域资源和unknown频域资源，具体的确定unknown时域资源和unknown频域资源的方式与图2中确定unknown时域资源和unknown频域资源的方式类似，在此不再赘述。It should be noted that, in the embodiment of the present application, when the mapping relationship between the index number and the time slot format is as shown in Table 2, the network device is configured as the uplink frequency domain resource and the downlink frequency domain resource configured for the terminal device. In the case of unpaired spectrum, any index number can be selected from Table 2, indicating to the terminal device that after receiving the index number sent by the network device, the terminal device further determines the unknown according to the index number and the frequency domain resource configuration information. The manner of determining the unknown time domain resource and the unknown frequency domain resource is similar to the method of determining the unknown time domain resource and the unknown frequency domain resource in FIG. 2 , and is not described here.

本申请实施例中在索引号与时隙的格式的对应关系如表3所示时，若一个时隙中包括14个符号，由于在网络设备为终端设备配置的上行频域资源和下行频域资源为unpaired spectrum的情况下，下行符号的个数、上行符号的个数和unknown符号的个数的总和不大于一个时隙中包括的符号的总数14，因此，网络设备在为终端设备配置的上行频域资源和下行频域资源为unpaired spectrum的情况下，从表3中选择索引号时，需要选择下行符号的个数、上行符号的个数和unknown符号的个数的总和不大于一个时隙中包括的符号的总数的时隙的格式的索引号，而在网络设备为终端设备配置的上行频域资源和下行频域资源为paired spectrum的情况下，下行符号的个数、上行符号的个数和unknown符号的个数的总和不大于一个时隙中包括的符号的总数的二倍(一个时隙中包括14个符号时，则时隙中包括的符号的二倍为28)，即网络设备在为终端设备配置的上行频域资源和下行频域资源为paired spectrum的情况下，从表3中选择索引号时，需要选择下行符号的个数、上行符号的个数和unknown符号的个数的总和不大于一个时隙中包括的符号的总数的二倍的时隙的格式的索引号。In the embodiment of the present application, when the correspondence between the index number and the format of the time slot is as shown in Table 3, if a time slot includes 14 symbols, the uplink frequency domain resource and the downlink frequency domain configured by the network device are terminal devices. When the resource is an unpaired spectrum, the sum of the number of downlink symbols, the number of uplink symbols, and the number of unknown symbols is not greater than the total number of symbols included in one slot. 14 Therefore, the network device is configured for the terminal device. When the uplink frequency domain resource and the downlink frequency domain resource are unpaired spectrum, when the index number is selected from Table 3, the sum of the number of downlink symbols, the number of uplink symbols, and the number of unknown symbols needs to be no more than one. The index number of the format of the slot of the total number of symbols included in the slot, and in the case where the uplink frequency domain resource and the downlink frequency domain resource configured by the network device for the terminal device are paired spectrum, the number of downlink symbols and the uplink symbol The sum of the number of the number and the unknown symbol is not more than twice the total number of symbols included in one slot (when 14 symbols are included in one slot, the slot is The number of symbols included in the signal is 28), that is, when the uplink frequency domain resource and the downlink frequency domain resource configured for the terminal device are paired spectrum, when selecting the index number from Table 3, the downlink symbol needs to be selected. The sum of the number, the number of uplink symbols, and the number of unknown symbols is not more than the index number of the format of the time slot twice the total number of symbols included in one slot.

本申请实施例中在索引号与时隙的格式的对应关系如表4所示时，在网络设备为终端设备配置的上行频域资源和下行频域资源为unpaired spectrum的情况下，与下行频域资源对应的unknown符号和与上行频域资源对应的unknown符号是相同的、且下行符号的个数、上行符号的个数和unknown符号的个数的总和不大于一个时隙中包括的符号的总数，因此网络设备在为终端设备配置的上行频域资源和下行频域资源为unpaired spectrum的情况下，从表4中选择索引号指示给终端设备时，需要选择满足与下行频域资源对应的unknown符号的个数和与上行频域资源对应的unknown符号的个数相等的、且下行符号的个数、上行符号的个数和与下行频域资源对应的unknown符号的个数的总和不大于一个时隙中包括的符号的总数中的时隙的格式的索引号。而对于网络设备在为终端设备配置的上行频域资源和下行频域资源为paired spectrum的情况下，可以从表4所示的索引号中选择任意一个索引号指示给终端设备，由终端设备根据索引号和频域资源配置信息确定unknown时频资源，unknown时频资源的确定方式与图2中unknown时频资源的确定方式类似，在此不在赘述。In the embodiment of the present application, when the correspondence between the index number and the time slot format is as shown in Table 4, in the case that the uplink frequency domain resource and the downlink frequency domain resource configured by the network device for the terminal device are unpaired spectrum, and the downlink frequency The unknown symbol corresponding to the domain resource is the same as the unknown symbol corresponding to the uplink frequency domain resource, and the sum of the number of downlink symbols, the number of uplink symbols, and the number of unknown symbols is not greater than the symbol included in one slot. If the uplink frequency domain resource and the downlink frequency domain resource configured for the terminal device are unpaired spectrum, if the network device selects the index number from the table 4 to indicate the terminal device, the network device needs to select and meet the downlink frequency domain resource. The sum of the number of unknown symbols and the number of unknown symbols corresponding to the uplink frequency domain resource, and the sum of the number of downlink symbols, the number of uplink symbols, and the number of unknown symbols corresponding to the downlink frequency domain resource is not greater than The index number of the format of the slot in the total number of symbols included in one slot. In the case that the uplink frequency domain resource and the downlink frequency domain resource configured for the terminal device are paired spectrum, the network device may select any index number from the index number shown in Table 4 to indicate the terminal device, and the terminal device according to the terminal device The index number and the frequency domain resource configuration information determine the unknown time-frequency resource. The method for determining the unknown time-frequency resource is similar to the method for determining the unknown time-frequency resource in FIG. 2, and is not described here.

本申请实施例中能够根据指示信息和频域资源配置信息确定时隙中的unknown时域资源，与现有技术相比，无需增加额外的信令来指示向终端设备指示网络设备使用的双工方式，有助于降低信令开销，以及有助于降低网络设备配置的复杂度。In the embodiment of the present application, the unknown time domain resource in the time slot can be determined according to the indication information and the frequency domain resource configuration information. Compared with the prior art, no additional signaling is needed to indicate to the terminal device that the duplex used by the network device is indicated. This helps reduce signaling overhead and helps reduce the complexity of network device configuration.

此外，由于终端设备可能在一个时间点存在只能够用于传输上行数据或者下行数据情况，在这种情况下，终端设备存在上行和下行状态的切换，而通常情况下终端设备需要一个过渡时间进行状态切换，该过渡时间可以称之为时间切换点，用于从上行到下行的切换，或者从下行到上行的切换。一般情况下，通常在时隙的格式中设置一个GP，由于为了简化实现方式，通常将GP配置在下行符号和上行符号之间，如图7所示，因此本申请实施例中为了简化实现方式，可以将该GP配置在下行符号和上行符号之间的unknown时域资源内，因此，本申请实施例中的unknown时域资源需要包括位于下行符号和上行符号之间的时域资源，在时隙的格式中设置一个GP的情况下，可选的，当时隙的格式包括下行符号的个数和上行符号的个数时，在预先配置指示信息指示的时隙的格式中下行符号的位置和上行符号的位置时，可以按照从第1个符号位置开始配置下行符号，从最后一个符号开始配置上行符号。In addition, since the terminal device may only be used for transmitting uplink data or downlink data at a certain time point, in this case, the terminal device has an uplink and downlink state switching, and usually the terminal device needs a transition time. State switching, which can be referred to as a time switching point, for switching from uplink to downlink, or switching from downlink to uplink. In general, a GP is usually set in the format of the time slot. In order to simplify the implementation, the GP is usually configured between the downlink symbol and the uplink symbol, as shown in FIG. The GP may be configured in the unknown time domain resource between the downlink symbol and the uplink symbol. Therefore, the unknown time domain resource in the embodiment of the present application needs to include the time domain resource between the downlink symbol and the uplink symbol. In the case where a GP is set in the format of the slot, optionally, when the format of the slot includes the number of downlink symbols and the number of uplink symbols, the position of the downlink symbol in the format of the slot indicated by the pre-configured indication information is When the position of the uplink symbol is set, the downlink symbol can be configured from the first symbol position, and the uplink symbol can be configured from the last symbol.

示例的，在上行频域资源的中心频点和下行频域资源的中心频点重合的情况下，以图5a所示的unknown时频资源为例，其中GP可以配置在第13个符号上；在上行频域资源的中心频点和下行频域资源的中心频点不重合的情况下，以图6所示的unknown时频资源为例，其中GP也通常配置在第13个符号上。For example, in the case where the center frequency of the uplink frequency domain resource and the center frequency of the downlink frequency domain resource coincide, the unknown time-frequency resource shown in FIG. 5a is taken as an example, wherein the GP can be configured on the 13th symbol; In the case where the center frequency of the uplink frequency domain resource and the center frequency of the downlink frequency domain resource do not coincide, the unknown time-frequency resource shown in FIG. 6 is taken as an example, and the GP is also usually configured on the 13th symbol.

另外，还可以在时隙的格式中设置两个GP，此时，为了满足将这两个GP配置在下行符号和上行符号之间的unknown时域资源内，可选的，指示信息在指示时隙的格式时，将时隙划分为第一部分和第二部分两部分进行指示，以指示信息为索引号为例，假设第一部分包括的符号个数和第二部分包括的符号个数相同，则索引号和时隙的格式的对应关系可以如表6所示。In addition, two GPs may be set in the format of the time slot. In this case, in order to satisfy the configuration of the two GPs in the unknown time domain resource between the downlink symbol and the uplink symbol, optionally, the indication information is indicated. In the format of the slot, the time slot is divided into two parts, the first part and the second part, to indicate that the information is an index number, and the first part includes the same number of symbols and the second part includes the same number of symbols. The correspondence between the index number and the format of the time slot can be as shown in Table 6.

表6Table 6

以一个时隙包括14个符号为例，其中第一部分包括7个符号，第二部分包括7个符号，若预先配置第一部分和第二部分下行符号的位置和上行符号的位置时，均按照从该部分第1个符号位置开始向后配置下行符号，从该部分最后一个符号开始向前配置上行符号，则索引号为1时，对应的时隙格式可以如图8a所示，因而，从图8a所示的时隙的格式中可以看出在第一部分unknown符号的位置位于下行符号和上行符号之间，在第二部分unknown符号的位置位于下行符号和上行符号之间，因此通过上述方式网络设备无需再向终端设备发送额外的信令指示GP。Taking a time slot including 14 symbols as an example, wherein the first part includes 7 symbols, and the second part includes 7 symbols, if the positions of the first part and the second part of the downlink symbol and the position of the uplink symbol are pre-configured, The first symbol position of the part starts to configure the downlink symbol backward, and the uplink symbol is configured from the last symbol of the part. When the index number is 1, the corresponding slot format can be as shown in FIG. 8a. In the format of the time slot shown in 8a, it can be seen that the position of the unknown part in the first part is located between the downlink symbol and the uplink symbol, and the position of the unknown symbol in the second part is located between the downlink symbol and the uplink symbol, so the network is obtained by the above manner. The device no longer needs to send an additional signaling indicator GP to the terminal device.

示例的，在时隙的格式中设置两个GP时，索引号和时隙的格式的对应关系还可以如表7所示。For example, when two GPs are set in the format of the time slot, the correspondence between the index number and the format of the time slot can also be as shown in Table 7.

表7Table 7

例如，假设一个时隙包括14个符号，索引号为1时对应的时隙格式可以如图8b所示，其中unknown符号被分为两部分，从图8b所示的时隙的格式中可以看出在第一部分unknown符号的位置位于下行符号和上行符号之间，在第二部分unknown符号的位置位于下行符号和上行符号之间。For example, if a time slot includes 14 symbols and the index number is 1, the corresponding slot format can be as shown in FIG. 8b, where the unknown symbol is divided into two parts, which can be seen from the format of the time slot shown in FIG. 8b. The position of the unknown symbol in the first part is located between the downlink symbol and the uplink symbol, and the position of the unknown symbol in the second part is located between the downlink symbol and the uplink symbol.

需要说明的是，还可以通过上述方式在时隙的格式中设置三个或更多个GP，在此不再赘述。It should be noted that three or more GPs may also be set in the format of the time slot in the above manner, and details are not described herein again.
