具体实施方式detailed description
下文中将结合附图对本申请的实施例进行说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。Hereinafter, the embodiments of the present application will be described with reference to the drawings. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.

在非授权频谱中，传输上行业务信号或者下行业务信号时，每个信号的时延是不相同的。在长期演进(Long Term Evolution，LTE)网络的授权频谱辅助接入(License Assisted Access，LAA)中，对于固定参考子帧的信号的解调状态 一定在固定的子帧接收。但是，在非授权频谱的新空口技术(New Radio in Unlicensed Spectrum，NRU)中，因为每个通信节点的传输单元中包含的信息对应不同的延时，同样，在每个相同的时域单元内接收端的解调信息对应不同的参考时域单元的信息。因此，对于固定参考子帧的信号的解调状态不一定在固定的子帧接收。In the unlicensed spectrum, when transmitting uplink service signals or downlink service signals, the time delay of each signal is different. In the License Assisted Access (LAA) of the Long Term Evolution (LTE) network, the demodulation state of the signal of the fixed reference subframe must be received in the fixed subframe. However, in the New Radio in Unlicensed Spectrum (NRU) of unlicensed spectrum, because the information contained in the transmission unit of each communication node corresponds to different delays, similarly, in each same time domain unit The demodulation information of the receiving end corresponds to the information of different reference time domain units. Therefore, the demodulation state of the signal of the fixed reference subframe is not necessarily received in the fixed subframe.
基于上述原因，本申请实施例提供一种信号发送方法，如图1所示，包括如下步骤：Based on the foregoing reasons, an embodiment of the present application provides a signal sending method, as shown in FIG. 1, including the following steps:

For example, greater than 8ms is a stage, and its corresponding weight is 0.2; greater than 4ms and less than 8ms is a stage, and its corresponding weight is 0.4; less than 4ms is another stage, and its corresponding weight is 0.8.
那么，上述时延信息对应的权重分别为：8.25ms对应的权重为0.2，6.125ms和6.75ms对应的权重为0.4，3.25ms对应的权重为0.8。Then, the weights corresponding to the above-mentioned delay information are respectively: the weight corresponding to 8.25ms is 0.2, the weight corresponding to 6.125ms and 6.75ms is 0.4, and the weight corresponding to 3.25ms is 0.8.
确定上述第一加权值的方式为1*0*0.2+1*0*0.4+1*1*0.4+3*1*0.8＝2.8，确定传输块加权值的方式为1*0.2+1*0.4+1*0.4+3*0.8＝3.4。The method for determining the above-mentioned first weighting value is 1*0*0.2+1*0*0.4+1*1*0.4+3*1*0.8=2.8, and the method for determining the weighting value of the transmission block is 1*0.2+1*0.4 +1*0.4+3*0.8=3.4.
1*0.2中的1表示一个min slot中与NACK对应的1个TB，0.2表示与该min slot延时对应的权重。The 1 in 1*0.2 represents 1 TB corresponding to NACK in a min slot, and 0.2 represents the weight corresponding to the min slot delay.
第一加权值在传输块加权值的中的比重为2.8/3.4＝0.82。假设预设门限为0.8，由于0.82大于0.8，则将CW值确定为CW值集合中的最小CW值。The proportion of the first weight value in the transmission block weight value is 2.8/3.4=0.82. Assuming that the preset threshold is 0.8, since 0.82 is greater than 0.8, the CW value is determined as the smallest CW value in the CW value set.
相反，当第一加权值在传输块加权值中的比重小于预设门限时，将CW值确定为CW值集合中不小于当前CW值的数值或者下一个允许的值。On the contrary, when the proportion of the first weight value in the transmission block weight value is less than the preset threshold, the CW value is determined as a value not less than the current CW value or the next allowed value in the CW value set.
S103、根据CW值发送目标信号。S103: Send the target signal according to the CW value.
由于第一信号为发送端已经发送的信号，根据已经发送信号的状态信息(例如，解调信息和/或时延信息)对CW值调整后，可以根据该CW值发送目标信号。Since the first signal is a signal already sent by the sending end, after the CW value is adjusted according to the status information of the sent signal (for example, demodulation information and/or delay information), the target signal can be sent according to the CW value.
本申请实施例提供了一种信号发送方法，在第一时域单位内接收第一信号，并根据第一信号的状态信息确定CW值，进而根据CW值发送目标信号，其中，第一时域单位为预设的时域单位或与最近一次突发传输burst相关的时间段，第 一信号的状态信息包括第一信号的解调信息。这样基于在第一时域单位内接收到的第一信号，根据第一信号的状态信息确定CW值，可以更加全面、准确的动态调整CW值。The embodiment of the present application provides a signal sending method.
