Description

Data transmission method, device and terminal

Technical field

本发明涉及通信技术领域，尤其涉及一种数据传输方法、装置及终端。The present invention relates to the field of communications technologies, and in particular, to a data transmission method, apparatus, and terminal.

Background technique

设备与设备(Device to Device，D2D)技术可以支持设备与设备之间的直接通信。LTE D2D有2种物理层传输信道：通信(communication)信道和发现(discovery)信道。Communication信道通过调度分配(scheduling assignment，SA)信息指示时域资源池中承载数据的时域位置。在LTE Rel.12 D2D Communication信道中，每个数据固定传输4次。在一个时域资源池内，通过SA信息中的传输的时间资源图样(Time Resource Pattern of Transmission，T-RPT)指示传输数据的时域位置。具体来说，T-RPT为一个7比特的索引值，使用该索引值通过查表可以得到一个位表(位表可以有不同长度，例如8比特)。位表的每一位分别对应一个子帧，该位为1，则表示发送端在该子帧有数据传输，如果该位为0，则表示发送端在该子帧无数据传输。时域资源池的长度可能大于位表的长度，将该位表在时域资源池内不断重复直至时域资源池结束。由于位表在整个时域资源池内不断重复，所有对应于位表中为1的子帧都要用于该数据的传输，则在一个位表指示的子帧中，数据至少要被传输1次假设位表在整个时域资源池内重复4次，则在一个时域资源池内发送端至少要传输4次数据，而且数据传输的次数为4的倍数，数据的传输次数无法改变，造成资源浪费。Device to Device (D2D) technology can support direct communication between devices and devices. LTE D2D has two physical layer transport channels: a communication channel and a discovery channel. The Communication channel indicates the time domain location of the data carried in the time domain resource pool by using scheduling assignment (SA) information. In the LTE Rel.12 D2D Communication channel, each data is fixedly transmitted 4 times. In a time domain resource pool, the time domain location of the transmitted data is indicated by a Time Resource Pattern of Transmission (T-RPT) in the SA information. Specifically, the T-RPT is a 7-bit index value, and a bit table can be obtained by looking up the table using the index value (the bit table can have different lengths, for example, 8 bits). Each bit of the bit table corresponds to one subframe. When the bit is 1, it indicates that the transmitting end has data transmission in the subframe. If the bit is 0, it indicates that the transmitting end has no data transmission in the subframe. The length of the time domain resource pool may be greater than the length of the bit table, and the bit table is repeated in the time domain resource pool until the time domain resource pool ends. Since the bit table is continuously repeated in the entire time domain resource pool, all subframes corresponding to 1 in the bit table are used for the transmission of the data, and the data is transmitted at least once in the subframe indicated by a bit table. Assuming that the bit table is repeated 4 times in the entire time domain resource pool, the transmitting end needs to transmit at least 4 times of data in a time domain resource pool, and the number of data transmission times is a multiple of 4, and the number of data transmission cannot be changed, resulting in waste of resources.

发明内容Summary of the invention

本申请提供一种数据传输方法、装置及终端，可灵活改变数据的传输次数，提升资源利用率。The present application provides a data transmission method, device and terminal, which can flexibly change the number of data transmissions and improve resource utilization.

第一方面提供了一种数据传输方法，包括：The first aspect provides a data transmission method, including:

发送端获取当前需要传输的数据的SA信息，SA信息用于指示时域资源池中可用于承载数据的时域位置；The sender obtains the SA information of the data that needs to be transmitted, and the SA information is used to indicate the time domain resource. The time domain location in the pool that can be used to host data;

发送端根据SA信息，在时域资源池中确定至少一个可用于传输数据的子资源池；The sending end determines, according to the SA information, at least one sub-resource pool that can be used for transmitting data in the time domain resource pool;

发送端根据调度分配信息，在各个可用于传输数据的子资源池中确定至少一个可用于传输数据的子帧；The transmitting end determines, according to the scheduling allocation information, at least one subframe that can be used for transmitting data in each of the sub-resource pools that can be used for transmitting data;

发送端通过至少一个可用于传输数据的子帧传输数据。The transmitting end transmits data through at least one subframe that can be used to transmit data.

在该技术方案中，发送端可以通过以下两种方式获取当前需要传输的数据的SA信息：一、发送端预先配置该数据的SA信息，即由发送端决定该数据的传输次数，可用于传输数据的子资源池，以及可用于传输数据的子资源池中可用于传输数据的子帧，其中该数据的传输次数为至少一次；二、发送端向基站发送对该数据的数据传输请求，并接收基站响应该数据传输请求所配置的对该数据的SA信息，即由基站决定该数据的传输次数，可用于传输数据的子资源池，以及可用于传输数据的子资源池中可用于传输数据的子帧，其中该数据的传输次数为至少一次。进一步的，发送端获取该数据的SA信息之后，可以根据SA信息，在时域资源池中确定至少一个可用于传输该数据的子资源池，并根据调度分配信息，在各个可用于传输数据的子资源池中确定至少一个可用于传输数据的子帧，进而通过至少一个可用于传输数据的子帧传输该数据。以图2所示的时域资源池的结构示意图为例，发送端可以将时域资源池划分为5个子资源池，每个子资源池包括8个子帧，如果该数据的重要等级较低，只需要传输一次即可，则发送端根据SA信息确定的可用于传输数据的子资源池为子资源池3，可用于传输数据的子帧为子帧2，该数据的传输次数为一次；如果该数据的重要等级较高，需要多次传输，以确保接收端成功接收该数据，则发送端根据SA信息确定的可用于传输数据的子资源池为子资源池3、4，各个可用于传输数据的子资源池中的可用于传输数据的子帧为子帧2、6、7，则该数据的传输次数为六次。因此，采用上述技术方案可灵活改变数据的传输次数，提升资源利用率。In the technical solution, the sending end can obtain the SA information of the data that needs to be transmitted in the following two manners: First, the sending end pre-configures the SA information of the data, that is, the transmitting end determines the number of times the data is transmitted, and can be used for transmitting. a sub-resource pool of data, and a sub-frame in the sub-resource pool that can be used for transmitting data, wherein the data is transmitted at least once; and the transmitting end sends a data transmission request for the data to the base station, and Receiving the SA information of the data configured by the base station in response to the data transmission request, that is, the number of transmissions of the data determined by the base station, the sub-resource pool that can be used for transmitting data, and the sub-resource pool that can be used for transmitting data can be used for transmitting data. Subframe, where the data is transmitted at least once. Further, after obtaining the SA information of the data, the sending end may determine, according to the SA information, at least one sub-resource pool that can be used for transmitting the data in the time domain resource pool, and according to the scheduling allocation information, each of the data that can be used for transmitting the data. At least one subframe that can be used to transmit data is determined in the child resource pool, and the data is transmitted through at least one subframe that can be used to transmit data. Taking the structure diagram of the time domain resource pool shown in Figure 2 as an example, the sender can divide the time domain resource pool into five sub-resource pools, and each sub-resource pool includes 8 subframes. If the importance level of the data is low, only The sub-resource pool that can be used for transmitting data according to the SA information is the sub-resource pool 3, and the sub-frame that can be used for transmitting data is the sub-frame 2, and the number of transmissions of the data is once; The data has a high importance level and needs to be transmitted multiple times to ensure that the receiving end successfully receives the data. The sub-resource pools that the transmitting end can use to transmit data according to the SA information are sub-resource pools 3 and 4, each of which can be used for transmitting data. The sub-frames in the sub-resource pool that can be used to transmit data are subframes 2, 6, and 7, and the data is transmitted six times. Therefore, the above technical solution can flexibly change the number of data transmissions and improve resource utilization.

其中，当前需要传输的数据可以为通知消息、确认消息、日志或者文件等，具体不受本发明实施例的限制。SA信息用于指示时域资源池中可用于承载数据的时域位置。时域资源池可以占用至少一个子帧，时域资源池为公共资源，不同发送端可以通过时域资源池中的不同子帧发送不同数据，或者同一发送端可以通过时域资源池中的不同子帧发送相同数据，等等，时域资源池所占用子帧的数量是由基站所配置的，例如，基站可以向至少两个终端广播通知消息，其中通知消息携带资源池信息，进而发送端可以获取该资源池信息，并确定时域资源池所占用子帧的数量。进一步的，时域资源池可以包括至少一个子资源池，各个子资源池中子帧的个数相同，所有子资源池中子帧个数的总和为时域资源池所占用的子帧，以图2所示的时域资源池的结构示意图为例，该时域资源池可以包括5个子资源池。The data that needs to be transmitted may be a notification message, a confirmation message, a log, a file, or the like, and is not limited by the embodiment of the present invention. The SA information is used to indicate the time domain location in the time domain resource pool that can be used to carry data. The time domain resource pool can occupy at least one subframe, and the time domain resource pool is a public resource. Different senders can send different data through different subframes in the time domain resource pool, or the same sender can send the same data through different subframes in the time domain resource pool, and so on, the number of subframes occupied by the time domain resource pool. The base station can be configured by the base station. For example, the base station can broadcast the notification message to the at least two terminals, where the notification message carries the resource pool information, and the sender can obtain the resource pool information and determine the number of subframes occupied by the time domain resource pool. . Further, the time domain resource pool may include at least one sub-resource pool, and the number of sub-frames in each sub-resource pool is the same, and the sum of the number of sub-frames in all sub-resource pools is a sub-frame occupied by the time domain resource pool. For example, the structure of the time domain resource pool shown in FIG. 2 may include five sub-resource pools.

在一个可能的设计中，SA信息可以包括子池指示信息，则发送端可以根据子池指示信息，在时域资源池中确定至少一个可用于传输数据的子资源池。In a possible design, the SA information may include sub-pool indication information, and the sender may determine at least one sub-resource pool that can be used for transmitting data in the time domain resource pool according to the sub-pool indication information.

其中，子池指示信息用于指示时域资源池中可用于传输数据的子资源池，子池指示信息可以为包括数码0和/或数码1的位串，或者子池指示信息可以为索引值，其中不同索引值对应不同的位串，该位串包括数码0和/或数码1，其中位串中的每个二进制位对应一个子资源池，数码1可以表示对应的子资源池为可用于传输数据的子资源池，数码0可以表示对应的子资源池中的各个子帧无需传输该数据。以图2所示的时域资源池的结构示意图为例，子池指示信息为10010，发送端将时域资源池划分为5个子资源池，则10010表示子资源池1、4为可用于传输数据的子资源池，子资源池2、3、5中的各个子帧无需传输该数据。又如，子池指示信息为0x00ff，发送端根据索引值和位串的对应关系，获取到该索引值对应的位串为10010，其中发送端将时域资源池划分为5个子资源池，则10010表示子资源池1、4为可用于传输数据的子资源池，子资源池2、3、5中的各个子帧无需传输该数据。The sub-pool indication information is used to indicate a sub-resource pool in the time-domain resource pool that can be used for transmitting data, and the sub-pool indication information may be a bit string including the digit 0 and/or the digit 1 or the sub-pool indication information may be an index value. The different index values correspond to different bit strings, and the bit string includes a digital 0 and/or a digital 1, wherein each binary bit in the bit string corresponds to a sub-resource pool, and the digital 1 can indicate that the corresponding sub-resource pool is available. The sub-resource pool for transmitting data, the digital 0 may indicate that each sub-frame in the corresponding sub-resource pool does not need to transmit the data. Take the structure diagram of the time domain resource pool shown in Figure 2 as an example. The sub-pool indication information is 10010. The sender divides the time domain resource pool into five sub-resource pools. 10010 indicates that the sub-resource pools 1 and 4 are available for transmission. The sub-resource pool of data, each sub-cell pool 2, 3, 5 does not need to transmit the data. For example, if the sub-pool indication information is 0x00ff, the sender obtains the bit string corresponding to the index value as 10010 according to the correspondence between the index value and the bit string, wherein the sender divides the time domain resource pool into five sub-resource pools. 10010 indicates that the sub-resource pools 1 and 4 are sub-resource pools that can be used to transmit data, and each of the sub-resource pools 2, 3, and 5 does not need to transmit the data.

需要说明的是，子池指示信息可以为位串或者索引值，不同索引值对应不同的位串，该位串可以包括数码0和/或数码1，其中位串中的每个二进制位对应一个子资源池，数码0可以表示对应的子资源池为可用于传输数据的子资源池，数码1可以表示对应的子资源池中的各个子帧无需传输该数据，具体不受本发明实施例的限制。It should be noted that the sub-pool indication information may be a bit string or an index value, and different index values correspond to different bit strings, and the bit string may include a digital 0 and/or a digital 1, where each binary bit in the bit string corresponds to one The sub-resource pool, the digital 0 may indicate that the corresponding sub-resource pool is a sub-resource pool that can be used for transmitting data, and the number 1 may indicate that each sub-frame in the corresponding sub-resource pool does not need to transmit the data, which is not specifically required by the embodiment of the present invention. limit.

The sub-pool indication information of different data may be different, and the sub-resource pool that can be used for transmitting data can be flexibly configured.

在一个可能的设计中，SA信息还可以包括T-RPT，发送端可以获取T-RPT对应的位表，并根据位表在各个可用于传输数据的子资源池中确定至少一个可用于传输数据的子帧。In a possible design, the SA information may further include a T-RPT, and the sender may obtain a bit table corresponding to the T-RPT, and determine, according to the bit table, at least one available for transmitting data in each of the sub-resource pools available for transmitting data. Subframe.

其中，位表用于指示各个可用于传输数据的子资源池中可用于传输数据的子帧，T-RPT和位表的对应关系可以沿用传统的T-RPT和位表的映射关系。具体实现中，位表可以为包括数码0和/或数码1的位串，其中位串中的每个二进制位对应一个子帧，数码1表示对应的子帧为可用于传输数据的子帧，数码0表示对应的子帧无需传输该数据。以图2所示的时域资源池的结构示意图为例，T-RPT对应的位表为01000110，则发送端可以确定各个可用于传输数据的子资源池中的子帧2、6、7为可用于传输数据的子帧。The bit table is used to indicate a subframe that can be used for transmitting data in each sub-resource pool that can be used for transmitting data, and the correspondence between the T-RPT and the bit table can follow the mapping relationship between the traditional T-RPT and the bit table. In a specific implementation, the bit table may be a bit string including a digital 0 and/or a digital 1, where each binary bit in the bit string corresponds to one subframe, and the digital 1 indicates that the corresponding subframe is a subframe that can be used for transmitting data. The digital 0 indicates that the corresponding subframe does not need to transmit the data. Taking the structure diagram of the time domain resource pool shown in FIG. 2 as an example, if the bit table corresponding to the T-RPT is 01000110, the sender can determine that the subframes 2, 6, and 7 in the sub-resource pools that can be used for transmitting data are A sub-frame that can be used to transmit data.

本发明实施例仍然沿用传统的T-RPT和位表的映射关系，仅将位表重新定义为指示各个可用于传输数据的子资源池中可用于传输数据的子帧，可降低数据传输系统的改进难度，降低开销。The embodiment of the present invention still uses the mapping relationship between the traditional T-RPT and the bit table, and only re-defines the bit table to indicate a sub-frame that can be used for transmitting data in each sub-resource pool that can be used for transmitting data, which can reduce the data transmission system. Improve difficulty and reduce overhead.

The correspondence between the T-RPT and the bit table can be followed by the mapping relationship between the traditional T-RPT and the bit table, and the sending end can also be connected to the base station. The correspondence between the T-RPT and the bit table is renegotiated, and is not specifically limited by the embodiment of the present invention. In a specific implementation, the bit table may be a bit string including digital 0 and/or digital 1, wherein each binary bit in the bit string corresponds to a sub-resource pool, and the digital 1 indicates that the corresponding sub-resource pool is a sub-resource for transmitting data. Resource pool, the number 0 indicates that each subframe in the corresponding sub-resource pool does not need to transmit the data.

本发明实施例仍然沿用传统的T-RPT和位表的映射关系，仅将位表重新定义为指示时域资源池中可用于传输数据的子资源池，可降低数据传输系统的改进难度，降低开销。 The embodiment of the present invention still uses the mapping relationship between the traditional T-RPT and the bit table, and only redefines the bit table to indicate a sub-resource pool that can be used for transmitting data in the time domain resource pool, which can reduce the improvement difficulty and reduce the data transmission system. Overhead.

在一个可能的设计中，SA信息还可以包括子帧指示信息，发送端可以根据子帧指示信息，在各个可用于传输数据的子资源池中确定至少一个可用于传输数据的子帧。In a possible design, the SA information may further include subframe indication information, and the transmitting end may determine, according to the subframe indication information, at least one subframe that can be used for transmitting data in each of the sub-resource pools available for transmitting data.

其中，子帧指示信息用于指示各个可用于传输数据的子资源池中可用于传输数据的子帧。子帧指示信息可以为包括数码0和/或数码1的位串，或者子帧指示信息可以为索引值，其中不同索引值对应不同的位串，该位串包括数码0和/或数码1，其中位串中的每个二进制位对应一个子帧，数码1可以表示对应的子帧为可用于传输数据的子帧，数码0可以表示对应的子帧无需传输该数据。以图2所示的时域资源池的结构示意图为例，子帧指示信息为01000110，发送端可以确定各个可用于传输数据的子资源池中的子帧2、6、7为可用于传输数据的子帧。The subframe indication information is used to indicate a subframe that is available for transmitting data in each of the sub-resource pools that can be used for transmitting data.

Taking the structure diagram of the time domain resource pool shown in FIG. 2 as an example, the subframe indication information is 01000110, and the sender can determine that the subframes 2, 6, and 7 in the sub-resource pools that can be used for transmitting data are available for transmitting data. Subframe.

需要说明的是，子帧指示信息可以为位串或者索引值，其中不同索引值对应不同的位串，该位串包括数码0和/或数码1，其中位串中的每个二进制位对应一个子帧，数码0可以表示对应的子帧为可用于传输数据的子帧，数码1可以表示对应的子帧无需传输该数据，具体不受本发明实施例的限制。It should be noted that the subframe indication information may be a bit string or an index value, where different index values correspond to different bit strings, and the bit string includes a digital 0 and/or a digital 1, where each binary bit in the bit string corresponds to one The sub-frame, the digital 0 can indicate that the corresponding sub-frame is a sub-frame that can be used for transmitting data, and the digital 1 can indicate that the corresponding sub-frame does not need to transmit the data, which is not limited by the embodiment of the present invention.

Subframe.

在一个可能的设计中，发送端根据SA信息，在时域资源池中确定至少一个可用于传输数据的子资源池之前，可以根据SA信息，将时域资源池划分为至少一个子资源池，各个子资源池包括至少一个子帧。In a possible design, the sender may divide the time domain resource pool into at least one sub-resource pool according to the SA information, according to the SA information, before determining at least one sub-resource pool that can be used for transmitting data in the time domain resource pool. Each sub-resource pool includes at least one sub-frame.

在一个可能的设计中，当SA信息包括T-RPT，且T-RPT对应的位表用于指示子帧时，发送端可以获取时域资源池的长度以及T-RPT对应的位表的长度，将位表的长度确定为各个子资源池中子帧的个数，将时域资源池的长度除以位表的长度，得到子资源池的个数，并根据子资源池的个数以及各个子资源池中子帧的个数，对时域资源池进行划分。In a possible design, when the SA information includes the T-RPT, and the bit table corresponding to the T-RPT is used to indicate the subframe, the sender can obtain the length of the time domain resource pool and the length of the bit table corresponding to the T-RPT. The length of the bit table is determined as the number of sub-frames in each sub-resource pool, and the length of the time-domain resource pool is divided by the length of the bit table to obtain the number of sub-resource pools, and according to the number of sub-resource pools and The number of sub-frames in each sub-resource pool is divided into time-domain resource pools.

具体实现中，基站可以向至少两个终端广播通知消息，其中通知消息携带资源池信息，进而发送端可以根据该资源池信息确定时域资源池的长度，其中时域资源池的长度即时域资源池所占用子帧的数量。位表的长度即位表中二进制位的个数。以图2所示的时域资源池的结构示意图为例，时域资源池所占用子帧的数量为40个，即时域资源池的长度为40ms(毫秒)，位表的长度为8bit(比特)，则发送端可以确定各个子资源池中子帧的个数为8个，一个子帧的长度为1ms，时域资源池中子资源池的个数为40/8＝5，进而发送端可以将时域资源池划分为5个子资源池，每个子资源池包括8个子帧。In a specific implementation, the base station may broadcast the notification message to the at least two terminals, where the notification message carries the resource pool information, and the sender may determine the length of the time domain resource pool according to the resource pool information, where the length of the time domain resource pool is the real-time domain resource. The number of subframes occupied by the pool. The length of the bit table is the second in the bit table The number of positions.

The sender can determine that the number of sub-frames in each sub-resource pool is eight, the length of one sub-frame is 1 ms, and the number of sub-resource pools in the time-domain resource pool is 40/8=5, and then the transmitting end The time domain resource pool can be divided into five sub-resource pools, and each sub-resource pool includes 8 subframes.

在一个可能的设计中，当SA信息包括子池指示信息时，发送端可以根据子池指示信息，确定子资源池的个数，获取时域资源池的长度，将时域资源池的长度除以子资源池的个数，得到各个子资源池中子帧的个数，根据子资源池的个数以及各个子资源池中子帧的个数，对时域资源池进行划分。In a possible design, when the SA information includes the sub-pool indication information, the sending end may determine the number of the sub-resource pools according to the sub-pool indication information, obtain the length of the time domain resource pool, and divide the length of the time domain resource pool. The number of sub-resource pools is obtained, and the number of sub-frames in each sub-resource pool is obtained. The time-domain resource pool is divided according to the number of sub-resource pools and the number of sub-frames in each sub-resource pool.

例如，当SA信息包括子池指示信息，且子池指示信息为包括数码0和/或数码1的位串时，发送端可以获取时域资源池的长度以及子池指示信息的长度，将子池指示信息的长度确定为子资源池的个数，将时域资源池的长度除以子池指示信息的长度，得到各个子资源池中子帧的个数，根据子资源池的个数以及各个子资源池中子帧的个数，对时域资源池进行划分。For example, when the SA information includes the sub-pool indication information, and the sub-pool indication information is a bit string including the digit 0 and/or the digit 1, the sender may acquire the length of the time domain resource pool and the length of the sub-pool indication information, The length of the pool indication information is determined as the number of the sub-resource pools, and the length of the sub-area resource pool is divided by the length of the sub-pool indication information to obtain the number of sub-frames in each sub-resource pool, according to the number of sub-resource pools and The number of sub-frames in each sub-resource pool is divided into time-domain resource pools.

具体实现中，时域资源池的长度为时域资源池所占用子帧的数量，子池指示信息的长度为子池指示信息中二进制位的个数。以图2所示的时域资源池的结构示意图为例，时域资源池所占用子帧的数量为40个，即时域资源池的长度为40ms，子池指示信息的长度为5bit，则发送端可以确定时域资源池中子资源池的个数为5个，各个子资源池中子帧的个数为40/5＝8，进而发送端可以将时域资源池划分为5个子资源池，每个子资源池包括8个子帧。In the specific implementation, the length of the time domain resource pool is the number of subframes occupied by the time domain resource pool, and the length of the subpool indication information is the number of binary bits in the subpool indication information. Take the structure diagram of the time domain resource pool shown in Figure 2 as an example. The number of sub-frames occupied by the time domain resource pool is 40, the length of the real-time domain resource pool is 40 ms, and the length of the sub-pool indication information is 5 bits. The terminal can determine that the number of sub-resource pools in the time-domain resource pool is five, and the number of sub-frames in each sub-resource pool is 40/5=8, and the sender can divide the time-domain resource pool into five sub-resource pools. Each sub-resource pool includes 8 sub-frames.

又如，当SA信息包括子池指示信息，且子池指示信息为索引值时，发送端可以获取该索引值对应的位串，该位串包括数码0和/或数码1。进一步的，发送端可以获取时域资源池的长度以及子池指示信息对应的位串的长度，将子池指示信息对应的位串的长度确定为子资源池的个数，将时域资源池的长度除以子池指示信息对应的位串的长度，得到各个子资源池中子帧的个数，根据子资源池的个数以及各个子资源池中子帧的个数，对时域资源池进行划分。具体不受本发明实施例的限制。For example, when the SA information includes the sub-pool indication information, and the sub-pool indication information is an index value, the transmitting end may acquire a bit string corresponding to the index value, where the bit string includes the digit 0 and/or the digit 1. Further, the sender can obtain the length of the time domain resource pool and the length of the bit string corresponding to the sub-pool indication information, and determine the length of the bit string corresponding to the sub-pool indication information as the number of the sub-resource pool, and the time-domain resource pool. The length of the bit string is divided by the length of the bit string corresponding to the sub-pool indication information, and the number of the sub-frames in each sub-resource pool is obtained. According to the number of sub-resource pools and the number of sub-frames in each sub-resource pool, the time-domain resources are used. The pool is divided. It is not specifically limited by the embodiments of the present invention.

在一个可能的设计中，当SA信息包括子帧指示信息时，发送端可以根据子帧指示信息，确定各个子资源池中子帧的个数，获取时域资源池的长度，将时域资源池的长度除以子资源池中子帧的个数，得到子资源池的个数，根据子资源池的个数以及各个子资源池中子帧的个数，对时域资源池进行划分。In a possible design, when the SA information includes the subframe indication information, the sending end may determine the number of subframes in each sub-resource pool according to the subframe indication information, and obtain the length of the time domain resource pool. Divide the length of the time domain resource pool by the number of sub-frames in the sub-resource pool, and obtain the number of sub-resource pools. According to the number of sub-resource pools and the number of sub-frames in each sub-resource pool, the time-domain resources are used. The pool is divided.

例如，当SA信息包括子帧指示信息，且子帧指示信息为包括数码0和/或数码1的位串时，发送端可以获取时域资源池的长度以及子帧指示信息的长度，将子帧指示信息的长度确定为各个子资源池中子帧的个数，将时域资源池的长度除以子帧指示信息的长度，得到子资源池的个数，并根据子资源池的个数以及各个子资源池中子帧的个数，对时域资源池进行划分。For example, when the SA information includes the subframe indication information, and the subframe indication information is a bit string including the digit 0 and/or the digit 1, the sender may acquire the length of the time domain resource pool and the length of the subframe indication information, and The length of the frame indication information is determined as the number of subframes in each sub-resource pool, and the length of the time domain resource pool is divided by the length of the sub-frame indication information to obtain the number of sub-resource pools, and according to the number of sub-resource pools. And the number of subframes in each sub-resource pool, and the time domain resource pool is divided.

具体实现中，子帧指示信息的长度为子帧指示信息中二进制位的个数。以图2所示的时域资源池的结构示意图为例，时域资源池所占用子帧的数量为40个，即时域资源池的长度为40ms，子帧指示信息的长度为8bit，则发送端可以确定各个子资源池中子帧的个数为8个，时域资源池中各个子资源池的个数为：40/8＝5，进而发送端可以将时域资源池划分为5个子资源池，每个子资源池包括8个子帧。In a specific implementation, the length of the subframe indication information is the number of binary bits in the subframe indication information. Take the structure diagram of the time domain resource pool shown in Figure 2 as an example. The number of sub-frames occupied by the time domain resource pool is 40, the length of the real-time domain resource pool is 40 ms, and the length of the sub-frame indication information is 8 bits. The number of the sub-resources in the sub-resource pool is eight, and the number of sub-resources in the time-domain resource pool is 40/8=5. The sender can divide the time-domain resource pool into five sub-children. A resource pool, each of which includes 8 subframes.

又如，当SA信息包括子帧指示信息，且子帧指示信息为索引值时，发送端可以获取该索引值对应的位串，该位串包括数码0和/或数码1。进一步的，发送端可以获取时域资源池的长度以及子帧指示信息对应的位串的长度，将子帧指示信息对应的位串的长度确定为各个子资源池中子帧的个数，将时域资源池的长度除以子帧指示信息对应的位串的长度，得到时域资源池中子资源池的个数，根据子资源池的个数以及各个子资源池中子帧的个数，对时域资源池进行划分。具体不受本发明实施例的限制。For another example, when the SA information includes the subframe indication information, and the subframe indication information is an index value, the transmitting end may acquire a bit string corresponding to the index value, where the bit string includes the digit 0 and/or the digit 1. Further, the sender may obtain the length of the time domain resource pool and the length of the bit string corresponding to the subframe indication information, and determine the length of the bit string corresponding to the subframe indication information as the number of subframes in each sub-resource pool, and The length of the time domain resource pool is divided by the length of the bit string corresponding to the subframe indication information, and the number of sub-resource pools in the time domain resource pool is obtained, according to the number of sub-resource pools and the number of sub-frames in each sub-resource pool. , divide the time domain resource pool. It is not specifically limited by the embodiments of the present invention.

在一个可能的设计中，当SA信息包括T-RPT，且T-RPT对应的位表用于指示子资源池时，发送端可以获取T-RPT对应的位表，获取时域资源池的长度以及位表的长度，将位表的长度确定为子资源池的个数，将时域资源池的长度除以位表的长度，得到各个子资源池中子帧的个数，并根据子资源池的个数以及各个子资源池中子帧的个数，对时域资源池进行划分。In a possible design, when the SA information includes the T-RPT, and the bit table corresponding to the T-RPT is used to indicate the sub-resource pool, the sender can obtain the bit table corresponding to the T-RPT, and obtain the length of the time domain resource pool. And the length of the bit table, the length of the bit table is determined as the number of the sub-resource pool, the length of the time domain resource pool is divided by the length of the bit table, and the number of sub-frames in each sub-resource pool is obtained, and according to the sub-resource The number of pools and the number of subframes in each sub-resource pool are divided into time-domain resource pools.

具体实现中，位表的长度即位表中二进制位的个数。例如，时域资源池的长度为40ms，位表的长度为8bit，则发送端可以确定时域资源池中子资源池的个数为8个，各个子资源池中子帧的个数为40/8＝5，进而发送端可以将时域资源池划分为8个子资源池，每个子资源池包括5个子帧。 In a specific implementation, the length of the bit table is the number of binary bits in the bit table. For example, if the length of the time domain resource pool is 40 ms and the length of the bit table is 8 bits, the sender can determine that the number of sub-resource pools in the time domain resource pool is eight, and the number of sub-frames in each sub-resource pool is 40. /8=5, the sender can divide the time domain resource pool into 8 sub-resource pools, and each sub-resource pool includes 5 subframes.

在一个可能的设计中，SA信息可以包括传输次数指示信息，则发送端可以根据传输次数指示信息，在所有可用于传输数据的子帧中确定用于传输数据的子帧，用于传输数据的子帧的个数与传输次数指示信息指示的传输次数相同，进而通过用于传输数据的子帧传输数据。In a possible design, the SA information may include the transmission frequency indication information, and the transmitting end may determine, according to the transmission frequency indication information, a subframe for transmitting data in all subframes available for transmitting data, for transmitting data. The number of subframes is the same as the number of transmissions indicated by the number-of-transmissions indication information, and the data is transmitted through the subframe for transmitting data.

其中，传输次数指示信息用于指示数据的传输次数。以图2所示的时域资源池的结构示意图为例，传输次数指示信息指示数据的传输次数为2次，发送端将时域资源池划分为5个子资源池，每个子资源池包括8个子帧，发送端根据SA信息确定子资源池1、4为可用于传输数据的子资源池，各个可用于传输数据的子资源池中的子帧2、6、7为可用于传输数据的子帧之后，可以在子资源池1中的子帧2、6、7以及子资源池4中的子帧2、6、7中确定2个用于传输数据的子帧，并通过上述2个用于传输数据的子帧传输该数据。进一步的，发送端可以将所有可用于传输数据的子帧中的前两个可用于传输数据的子帧作为用于传输数据的子帧，例如将子资源池1中的子帧2、6确定为用于传输数据的子帧，需要说明的是，本发明实施例包含但不局限于上述用于传输数据的子帧的确定方式，例如发送端可以将在所有可用于传输数据的子帧中随机选择的2个可用于传输数据的子帧作为用于传输数据的子帧。The transmission number indication information is used to indicate the number of times of data transmission. Taking the structure diagram of the time domain resource pool shown in FIG. 2 as an example, the number of transmissions indicates that the number of data transmissions is two, and the sender divides the time domain resource pool into five sub-resource pools, and each sub-resource pool includes eight sub-resources. The frame, the transmitting end determines, according to the SA information, the sub-resource pools 1, 4 are sub-resource pools that can be used for transmitting data, and the sub-frames 2, 6, and 7 in the sub-resource pools that can be used for transmitting data are sub-frames that can be used for transmitting data. Thereafter, two subframes for transmitting data may be determined in subframes 2, 6, and 7 in the sub-resource pool 1, and subframes 2, 6, and 7 in the sub-resource pool 4, and are used for the above two by The data is transmitted in a subframe in which data is transmitted. Further, the transmitting end may use the first two subframes in the subframes that can be used for transmitting data to transmit data as a subframe for transmitting data, for example, determining subframes 2 and 6 in the sub-resource pool 1. For a subframe for transmitting data, it should be noted that the embodiment of the present invention includes, but is not limited to, the foregoing determining manner of a subframe for transmitting data, for example, the transmitting end may be in all subframes that can be used for transmitting data. Two randomly selected subframes for transmitting data are used as subframes for transmitting data.

The number of times is the same, and each data is transmitted through a subframe for transmitting data in each subframe set. The number of subframe sets is the same as the number of data.

以图2所示的时域资源池的结构示意图为例，如果当前需要传输的数据为2个，即第一数据和第二数据，上述2个数据的传输次数均为2次，且SA信息相同，则发送端可以根据SA信息将时域资源池划分为5个子资源池，每个子资源池包括8个子帧，发送端根据SA信息确定子资源池1、4为可用于传输数据的子资源池，各个可用于传输数据的子资源池中的子帧2、6、7为可用于传输数据的子帧之后，可以在子资源池1中的子帧2、6、7以及子资源池4中的子帧2、6、7中确定2个子帧集，每个子帧集包括2个用于传输数据的子帧，并通过子帧集1中的各个用于传输数据的子帧传输第一数据，通过子帧集2中的各个用于传输数据的子帧传输第二数据。进一步的，发送端可以将所有可用于传输数据的子帧中的前两个可用于传输数据的子帧作为子帧集1中的用于传输数据的子帧，将与上述两个用于传输数据的子帧相邻的两个可用于传输数据的子帧作为子帧集2中的用于传输数据的子帧，例如将子资源池1中的子帧2、6确定为子帧集1中的用于传输数据的子帧，将子资源池1中的子帧7以及子资源池2中的子帧2确定为子帧集2中的用于传输数据的子帧，需要说明的是，本发明实施例包含但不局限于上述确定方式，例如发送端可以将在所有可用于传输数据的子帧中随机选择的可用于传输数据的子帧作为用于传输数据的子帧，并随机确定用于传输数据的子帧所属的子帧集。Taking the structure diagram of the time domain resource pool shown in FIG. 2 as an example, if the current data to be transmitted is two, that is, the first data and the second data, the number of transmissions of the two data is two times, and the SA information is If the same, the sender can divide the time domain resource pool into five sub-resource pools according to the SA information, and each sub-resource pool includes eight sub-frames. The sender determines that the sub-resource pools 1 and 4 are sub-resources that can be used for transmitting data according to the SA information. Pool, sub-frames 2, 6, and 7 in each sub-resource pool that can be used to transmit data are available After the subframe in which the data is transmitted, two subframe sets may be determined in the subframes 2, 6, and 7 in the sub-resource pool 1, and the subframes 2, 6, and 7 in the sub-resource pool 4, each of the subframe sets includes 2 A subframe for transmitting data, and transmitting the first data through each of the subframes for transmitting data in the subframe set 1, and transmitting the second data through each of the subframes for transmitting the data in the subframe set 2.
