Description

频谱资源共享方法、基站及计算机可读存储介质
本申请要求于2021年10月22日提交中国专利局、申请号为202111235933.5、发明名称为“频谱资源共享方法、基站及计算机可读存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，特别是涉及一种频谱资源共享方法、基站及计算机可读存储介质。
背景技术
频分双工(frequency-division duplexing，FDD)频谱共享(dynamic spectrum sharing，DSS)是一种第五代移动通信(新空口)技术(new radio，NR)和第四代移动通信(长期演进)技术(long term evolution，LTE)共用相同频谱资源部署NR和LTE网络的技术。由于稀缺的频谱资源，部分运营商无法独立部署5G网络，另一方面，在5G建设初期，支持5G的终端渗透率不高，单独部署5G网络将导致频谱资源利用效率较低，使得部署5G网络的投资大但收益少。FDD DSS利用LTE存量频谱，在此基础上部署5G网络，帮助运营商实现以低成本快速部署5G网络，打响品牌竞争力的目的。
在部署FDD DSS频谱过程中，LTE和NR的物理信道需要进行相互避让以避免冲突，并且，LTE和NR的将会在同一频谱上发送各自的固定信道。与相同频谱带宽大小的NR ONLY网络相比，NR DSS网络额外引入了LTE小区参考信号(cell reference signal，CRS)，物理下行控制信道(Physical Downlink Control Channel，PDCCH)，以及LTE系统消息的频谱资源开销，使得NR DSS网络的总可用频谱资源低于相同带宽下的NR ONLY网络，NR DSS网络的吞吐率峰值低于NR ONLY网络。

在一些可能实现的方式中，LTE系统的配置为4天线端口，方法还包括：基站将下行业务数据映射到子帧中的第二目标RE，第二目标RE为子帧中符号1的未被LTE系统的参考信道占用的RE。当LTE系统还占用符号1上的资源单元但实际没有利用的需求时，LTE系统在 符号1上占用的部分时频资源同样可以让出给NR系统，进一步提高频谱资源的利用率。
在一些可能实现的方式中，LTE系统的配置为4天线端口，方法还包括：当RRC连接态用户数不等于0时，基站获取LTE系统的控制格式指示CFI的值；当CFI的值为1时，基站将下行业务数据映射到子帧中的第三目标RE，第三目标RE为子帧中符号1的未被LTE系统的信道占用的RE。CFI的值为1说明符号1上的部分时频资源LTE系统无需求不使用，则可以将符号1上不使用的频谱资源让出给NR系统。
在一些可能实现的方式中，方法还包括：基站根据LTE系统的天线端口数量确定NR系统的控制信道占用的目标符号；基站对所下行业务数据进行速率匹配处理，以避让所目标符号中的RE。

具体实施方式
本申请实施例提供了一种频谱资源共享方法、基站及计算机可读存储介质，用于提高频分双工频谱共享的场景下频谱资源的利用率。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请实施例可以适用于通信系统，如图1所示，图1为本申请提供的通信系统的示意图。通信系统中包括基站和终端，终端是与基站进行通信的用户设备，包括4G终端和5G终端，对应本申请实施例中目标LTE小区的终端和目标NR小区的终端，基站为双制式基站，一种是LTE，另一种是NR，LTE系统与NR系统所使用的频谱部分重叠或全部重叠。基站包含至少一个LTE小区和至少一个NR小区，LTE小区的数目与NR小区的数目相同。
NR系统与LTE系统的子载波的间隔相等，如子载波的间隔都是15KHZ，如此可使NR系统和LTE系统的子载波正交，可以降低子载波之间的干扰。NR系统与LTE系统的子载波的OFDM符号的长度相等，如正交频分复用(orthogonal frequency division multiplexing，OFDM)符号的长度都是七分之一毫秒等。当然，NR系统与LTE系统的子载波的间隔也可以相等，该情况下，需要在NR系统与LTE系统之间预留一定的保护间隔，以降低子载波之间的干扰。
另外，NR系统与LTE系统的子载波的循环前缀(Cyclic Prefix，CP)长度相等，循环前缀是指OFDM符号在进入信道之前，加入的前缀，用于填充保护间隔。
如图2所示，图2为本申请提供的频谱资源共享方法一实施例的流程示意图。本实施例的执行主体为基站，本实施例包括如下步骤：
S201：基站获取LTE小区的RRC连接态用户数。
当用户终端处于无线资源控制(radio resource control，RRC)连接态时，说明该用户终端与基站有业务运行。基站获取LTE小区的RRC连接态用户数，能够根据RRC连接态用户数确定LTE小区对频谱需求情况。
S202：当RRC连接态用户数等于0时，基站将子帧中LTE系统占用的PCFICH和PHICH打孔，并将NR系统的下行业务数据映射到子帧中的第一目元RE。
其中，物理控制格式指示信道(physical control format indicator channel， PCFICH)，物理控制格式指示信道，指明了控制信息所在的位置。PCFICH是LTE系统的OFDM特性强相关的信道，承载的是控制信道在OFDM符号中的位置信息。物理混合自动重传指示信道(physical hybird ARQ indicator channel，PHICH)物理HARQ指示信道，承载的是混合自动重传请求(hybrid sutomatic repeat request，HARQ)的确认/非确定(ACK/NACK)信息。
第一目标资源单元(resource element，RE)为子帧中符号0的未被LTE系统的参考信道占用的RE，包括PCFICH占用的RE、PHICH占用的RE和物理下行控制信道(physical downlink control channel，PDCCH)占用的RE。子帧可以为多播/组播单频网络(multicast broadcast single frequency network，MBSFN)子帧，也可以为非MBSFN子帧。MBSFN子帧可以不发送CRS，只需要1～2个符号发送PCFICH、PHICH和PDCCH，因而本申请的方案同样适用于MBSFN子帧，从而不同类型子帧中的时频资源都能够得到充分、有效地利用。
LTE小区中RRC连接态用户数等于0，说明当前LTE小区内无用户需要传输数据，也就是LTE系统控制信道占用的频谱资源不会被使用，因此LTE系统在子帧中占用的控制信道则可以让出给NR系统。
具体地，由于PCFICH和PHICH通常映射在子帧的符号0对应的资源单元上，因此基站对LTE系统占用的PCFICH和PHICH进行打孔处理，以让出PCFICH和PHICH在符号0上占用的频谱资源。由于LTE系统中的小区参考信号(cell reference signal，CRS)是在整个系统带宽上离散发送，无论LTE小区是否有用户接收下行数据，CRS都会全带宽发送，NR系统需要对CRS进行避让。因此，基站进一步可以调用符号0上除LTE系统的CRS占用的RE(包括已打孔的PCFICH和PHICH占用的RE)给NR系统，从而提高频谱资源的利用率，进而提高NR DSS的峰值吞吐率。
LTE系统可以是配置为1天线端口、2天线端口或4天线端口。LTE系统的配置为1天线端口或2天线端口的情况下，LTE系统的控制信道占用子帧符号0上的RE；LTE系统的配置为4天线端口的情况下，LTE系统的控制信道占用子帧符号0和1上的RE。因此，相较于1天线端口和2天线端口，当LTE系统的配置为4天线端口，且LTE小区的RRC连接态用户数为0时，基站还可以将NR系统的下行业务数据映射到子帧中符号1的未被LTE系统的CRS占用的RE中，即第二目标RE上。第二目标RE具体例如是符号1上的LTE系统的PDCCH占用的RE。
举例说明，如图3所示，图3为RCC连接态用户数为0，LTE天线端口为1或2时子帧内一个资源块的时频资源映射示意图。可以理解，本申请实施例附图中CRS信道的位置和数量仅作为示例，不作为对本申请的限制。LTE天线端口为1或2时，LTE系统占用符号0作为控制信道，NR系统占用符号1作为控制信道，符号2至13作为NR系统的下行业务信道。由于RCC连接态用户数为0，那么符号0上的除LTE系统的CRS占用的RE以外的RE均未被利用，因此可以将符号0上的PCFICH和PHICH占用的RE调用给NR系统传输下行业务数据。
如图4所示，图4为RCC连接态用户数为0，LTE天线端口为4时子帧内一个资源块的时频资源映射示意图。LTE天线端口为4时，LTE系统占用符号0和1作为控制信道，NR系统占用符号2作为控制信道，符号3至13作为NR系统的下行业务信道。由于RCC连接态用户数为0，那么符号0和1上的除LTE系统的CRS占用的RE以外的RE均未被利用，因此除了 将符号0上的PCFICH和PHICH占用的RE调用给NR系统传输下行业务数据，还可以将符号1上的未被LTE系统的CRS占用的RE让出给NR系统传输下行业务数据。
当LTE系统的配置为4天线端口，但RCC连接态用户数不为0时，基站进一步获取LTE系统的控制格式指示(control format indicatior，CFI)的值。CFI用于指示LTE系统控制信道占用的符号数，当CFI的值为1时，说明LTE系统需要占用1个符号即符号0作为控制信道。而符号1上的部分RE不会被LTE系统使用，因此基站可以将下行业务数据映射到子帧中的第三目标RE，第三目标RE为子帧中符号1的未被LTE系统的信道占用的RE，即第三目标RE为符号1上未被LTE系统的参考信号及下行业务数据占用的RE。
举例说明，如图5所示，图5为本申请提供的LTE天线端口为4、CFI为1时一子帧的资源映射示意图。其中，LTE系统占用符号0作为控制信道，并占用符号1至13上的部分RE发送LTE下行业务数据。NR系统占用符号3上的部分RE作为控制信道，符号4至13上的部分RE发送NR下行业务数据。由于符号1上剩余的部分RE(未被LTE系统的参考信号及下行业务数据占用的RE)空闲，因此可以将符号1上的空闲的RE作为第三目标RE发送NR下行业务数据。
一般情况下，业务信道映射到控制信道占用的符号之后的符号上，由于本申请NR下行业务数据映射到NR控制信道之前的RE上，因此NR下行业务数据需要对NR控制信道进行避让。具体地，基站根据LTE系统的天线端口数量确定NR系统的控制信道占用的目标符号。例如，LTE天线端口为1或2时，NR系统的控制信道占用符号1，目标符号为1；LTE天线端口为4时，NR系统的控制信道占用符号2，目标符号为2。基站对所下行业务数据进行符号-RB级速率匹配处理，以便NR系统知道哪些RE不可用于在下行业务数据上进行NR数据调度，以避让所目标符号中的RE。
本实施例中，基站通过确认LTE系统占用的符号中的控制信道未被充分使用时，调度其中空闲的RE发送NR下行业务数据，从而提高LTE和NR动态频谱共享场景下的频谱资源利用率，进而提高NR系统的下行业务数据的吞吐率。
为了验证本申请实施例的有益效果，基于上述实施例进行了测试：20M等带宽DSS场景，LTE小区内无RRC连接态用户时，NR下行峰值测试。测试结果：基线FDD DSS场景下(不使用本申请技术方案)，NR DSS下行峰值吞吐率测得为321.1Mbit/s，使用本发明承载功能后，NR DSS下行峰值吞吐率测得的为366.53Mbit/s，增益达14.1％。
本申请提供的技术方案可降低LTE PDCCH对NR DSS的固定开销，最大降低开销幅度如下表所示：
