Description

一种LBT成功子带的指示方法、装置及基站A method, device and base station for indicating successful LBT subbands

技术领域technical field

本发明涉及无线通信技术领域，尤其涉及一种LBT成功子带的指示方法、装置及基站。The present invention relates to the technical field of wireless communication, in particular to a method, device and base station for indicating an LBT successful subband.

背景技术Background technique

在NR非授权频谱系统中，基站想要通过某个信道传输数据给用户，必须先通过“先听后说”(ListenBefore Talk，LBT)机制检测某个信道是否空闲。基站在多个subband上进行LBT时，由于LBT过程的不确定性导致不一定所有的subband都能LBT成功。在RAN1#96bits会议上达成的协议提到支持三种方式将基站LBT成功的subbandindex信息传输给UE，以了解哪些LBT subband是成功的。其中一种方式基站是将LBT成功的subband index放进到不同的PDCCH DMRS序列中，通过选择一个PDCCH DMRS序列，得出相应的LBT成功的subband情况，并显示的将信息发送给UE。In the NR unlicensed spectrum system, if the base station wants to transmit data to the user through a certain channel, it must first detect whether a certain channel is idle through the "Listen Before Talk (LBT)" mechanism. When the base station performs LBT on multiple subbands, due to the uncertainty of the LBT process, not all subbands can be successfully LBTed. The agreement reached at the RAN1#96bits meeting mentioned that three ways are supported to transmit the successful subbandindex information of the base station LBT to the UE to know which LBT subbands are successful. One of the ways is that the base station puts the subband index of successful LBT into different PDCCH DMRS sequences, obtains the corresponding subband situation of successful LBT by selecting a PDCCH DMRS sequence, and sends the information to the UE in a displayed manner.

但是，对于基站如何将LBT成功的subband信息通过PDCCH DMRS序列传输给UE，目前并没有达成统一的解决方案。However, there is currently no unified solution for how the base station transmits the subband information of successful LBT to the UE through the PDCCH DMRS sequence.

and l are changed to the bitmap of the successfully transmitted LBT. For example, when there are 4 LBT subbands, the bitmap of the successful transmission of the 4 subbands is: 1111, as shown in Figure 2, the bitmap is: 1011, indicating that the second subband failed.

然后对应出相应的十进制值，和

实施例二Embodiment two

本实施例所述方法与上述实施例方法不同在于：所述DMRS生成序列中的初始值内包括LBT成功子带的检测信息为在初始值内的第二参数中包括LBT成功子带的检测信息。The method described in this embodiment is different from the method in the above embodiment in that: the detection information including the LBT successful subband in the initial value in the DMRS generation sequence is the detection information including the LBT successful subband in the second parameter in the initial value .

可选地，在所述在初始值内的第二参数中包括LBT成功子带的检测信息中包括：Optionally, the detection information including the LBT successful subband in the second parameter in the initial value includes:

在作为第二参数的NID中包括LBT成功子带的bitmap；Include the bitmap of the LBT success subband in the N ID as the second parameter;

根据作为第二参数的NID生成对应PDCCH的DMRS生成序列。Generate a DMRS generation sequence corresponding to the PDCCH according to the N ID as the second parameter.

具体的，本实施例所述方法首先对PDCCH的DMRS生成序列中的

Figure GDA0003921913890000082
进行修改。将作为第二参数的NID中包括LBT成功子带的bitmap。由于作为第二参数的NID是16位的，根据LBT子带的数量在作为第二参数的NID中匹配对应位数进行指示即可。Specifically, the method described in this embodiment first generates the DMRS of the PDCCH in the sequence
Figure GDA0003921913890000082
to modify. The N ID that will be used as the second parameter includes the bitmap of the LBT success subband. Since the N ID as the second parameter is 16 bits, it is sufficient to match the corresponding number of bits in the N ID as the second parameter according to the number of LBT subbands for indication.

例如，当具有4个LBT subband时，则可用后面4位指示index，具体方法如下：For example, when there are 4 LBT subbands, the next 4 bits can be used to indicate the index, and the specific method is as follows:

当4个subband均成功传输时：则bitmap为：0000000000001111When all 4 subbands are successfully transmitted: the bitmap is: 0000000000001111

如图2所示，则bitmap为：0000000000001011，且表示第二个subband失败；As shown in Figure 2, the bitmap is: 0000000000001011, which means that the second subband failed;

例如，当具有4个LBT subband,时，则还可用前面4位指示index，具体方法如下：For example, when there are 4 LBT subbands, the first 4 bits can also be used to indicate the index, and the specific method is as follows:

当4个subband均成功传输时：则bitmap为：1111000000000000When all 4 subbands are successfully transmitted: the bitmap is: 1111000000000000

如图2所示，则bitmap为：1011000000000000，且表示第二个subband失败。As shown in Figure 2, the bitmap is: 1011000000000000, which indicates that the second subband failed.

另外，不局限于上述两种方式指示index，可根据LBT子带的数量随意选择用哪几位指示index。In addition, the index is not limited to the above two ways, and which bits to use to indicate the index can be selected arbitrarily according to the number of LBT subbands.

因此，基站可以生成包括LBT成功子带的检测信息的PDCCH的DMRS生成序列；以防基站在LBT成功以后，不能立即将LBT成功子带的检测信息放进PDCCH的DMRS生成序列中，另外，基站还可提前准备好具有几种可能LBT成功子带的检测信息的PDCCH的DMRS序列，UE根据匹配到的DMRS序列，就能匹配出对应的subband指示。Therefore, the base station can generate the DMRS generation sequence of the PDCCH including the detection information of the LBT successful subband; in case the base station cannot immediately put the detection information of the LBT successful subband into the DMRS generation sequence of the PDCCH after the LBT succeeds, in addition, the base station The DMRS sequence of the PDCCH with the detection information of several possible LBT successful subbands can also be prepared in advance, and the UE can match the corresponding subband indication according to the matched DMRS sequence.
