Description

一种信道跳频的确定方法及装置、计算机存储介质 技术领域
本发明涉及移动通信领域中的跳频技术，尤其涉及一种信道跳频的确定方法及装置、计算机存储介质。
背景技术
在长期演进(LTE，Long Term Evolution)系统中，物理上行控制信道(PUCCH，Physical Uplink Control CHannel)可采用跳频技术，以获得频域分集增益，提高信道传输性能。在LTE中，PUCCH跳频的第一步和第二步是以系统带宽的中心镜像对称的，如图1所示，第一步与系统带宽下边缘的距离和第二步与系统带宽上边缘的距离保持一致，均为D。
上述针对PUCCH跳频的设计可以将PUCCH分布在系统带宽两侧，以便将系统带宽的中央部分留给数据信道，如物理上行共享信道(PUSCH，Physical Uplink Shared Channel)，但将造成不同终端的PUCCH跳频步长不同。如图2所示，一些终端的跳频步长较大，PUCCH更靠近系统带宽边缘，频域分集效果更佳，传输性能更好；而另一些终端的跳频步长较小，PUCCH更靠近系统带宽中央，频域分集效果更差，传输性能较差。可见，传统的PUCCH跳频的设计造成PUCCH跳频步长不稳定，在PUCCH容量较大时，导致部分终端的PUCCH传输性能下降。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
第五代移动通信(5G NR)系统是未来移动通信系统研究的方向。在5G NR系统中，一方面，为了增加频域资源分配的灵活性、降低终端耗电， 5G NR终端可以在小于系统带宽的带宽分段(Bandwidth Part)中传输信号，当带宽分段的带宽较小时，位于中央的PUCCH的跳频步长会进一步缩小，影响PUCCH传输性能。另一方面，由于5G NR引入了一系列新技术，如新型多入多出(MIMO，Multiple-Input Multiple-Output)技术，需要更大数量的信道状态信息上报(CSI report)，PUCCH的负载大幅增大，这会造成PUCCH在带宽分段中占用更大比例的频域资源，靠近带宽分段中央的PUCCH跳频步长变得更小，传输性能进一步恶化。
为此，本发明实施例提出了一种信道跳频的确定方法，可以在给定带宽分段的宽带大小的情况下，实现稳定的跳频步长，从而获得更稳定的频域分集增益，改善了上行信道(尤其是上行控制信道)的传输性能。
图3为本发明实施例的信道跳频的确定方法的流程示意图，如图3所示，所述信道跳频的确定方法包括以下步骤：
步骤301：终端确定带宽分段对应的第一带宽，所述带宽分段对应的第一带宽小于系统带宽对应的第二带宽。
本发明实施例中，终端的类型并不受限制，终端可以是手机、笔记本、平板电脑、台式机、车载终端、智能家居终端等任意类型。
本发明实施例中，将基站支持的带宽称为系统带宽，也即第二带宽。在LTE中，终端可以在整个系统带宽范围内传输信号。在5G NR系统中，终端只在系统带宽的一部分传输信号，这里，系统带宽的一部分称为带宽分段，通过带宽分段能够有效提高系统带宽的资源利用效率。
本发明实施例中，上行信道可以采用跳频方式进行传输，以跳频包括两步为例，跳频的第一步与跳频的第二步在频域上的差值即为跳频步长，跳频步长的大小决定了上行信道的频域分集增益，跳频步长越大，上行信道的频域分集增益越大，相反，跳频步长越小，上行信道的频域分集增益越小。为了得到稳定且较大的频域分集增益，本发明实施例基于带宽分段对应的第一带宽来确定上行信道对应的跳频步长，以改善上行信道(尤其是上行控制信道)的传输性能。
具体地，终端需要首先确定带宽分段对应的第一带宽，显然，带宽分段对应的第一带宽小于系统带宽对应的第二带宽。
本发明实施例中，终端接收第一配置信息，基于所述第一配置信息确定所述带宽分段对应的第一带宽。
这里，终端接收第一配置信息可以通过以下两种方式实现：
方式一：终端接收携带所述第一配置信息的RRC信令。
方式二：终端接收携带所述第一配置信息的系统信息。
上述方案中，终端接收到的第一配置信息的个数可以是一个，也可以是多个，这里，多个的意思是指大于等于两个。
所述终端接收到一个第一配置信息时，基于所述一个第一配置信息确定所述带宽分段对应的第一带宽。
所述终端接收到多个第一配置信息时，基于所述多个第一配置信息确定所述带宽分段对应的多个候选第一带宽；从所述多个候选第一带宽中选择出所述带宽分段对应的第一带宽。
这里，终端接收第一控制信令，根据所述第一控制信令从所述多个候选第一带宽中选择出所述带宽分段对应的第一带宽。其中，所述第一控制信令为：DCI、或令MAC CE。
步骤302：所述终端基于所述带宽分段对应的第一带宽，确定上行信道对应的跳频步长。
本发明实施例中，终端基于以下公式确定所述上行信道对应的跳频步长：W H＝nW，
其中，W H为上行信道对应的跳频步长，W为带宽分段对应的第一带宽，n为比例系数，n＝1/m，m为大于1的正整数。
基于公式W H＝nW确定所述W H时，
Figure PCTCN2018083985-appb-000009
或
Figure PCTCN2018083985-appb-000010
其中，
Figure PCTCN2018083985-appb-000011
表示大于nW的最小整数，
Figure PCTCN2018083985-appb-000012
表示小于nW的最大整数。
考虑到跳频步长等于频域调度单元的整数倍才有实际意义，因此本发明实施例中W H的取值为整数。
例如，n可以是1/2，1/4等，不同的终端可以对应相同的n值，或者，不同的终端对应不同的n值。
上述方案中，终端需要先确定n或W H，具体地，终端基于预设值确定所述n或W H；或者，终端接收第二配置信息，基于所述第二配置信息确定所述n或W H。
这里，终端接收第二配置信息可以通过以下两种方式实现：
方式一：终端接收携带所述第二配置信息的RRC信令。
方式二：终端接收携带所述第二配置信息的系统信息。
在本发明一实施方式中，所述第二配置信息与所述第一配置信息为同一配置信息。
上述方案中，终端接收到的第二配置信息的个数可以是一个，也可以是多个。
所述终端接收到一个第二配置信息时，基于所述一个第二配置信息确定所述n或W H。
所述终端接收到多个第二配置信息时，基于所述多个第二配置信息确定多个候选n或W H；从所述多个候选n或W H中选择出所述n或W H。
这里，终端接收第二控制信令，根据所述第二控制信令从所述多个候选n或W H中选择出所述n或W H。其中，所述第二控制信令为：DCI、或MAC CE。
在本发明一实施方式中，所述第二控制信令与所述第一控制信令为同一控制信令。
步骤303：所述终端基于所述上行信道对应的跳频步长，确定用于传输 上行信道的频域位置。
本发明实施例中，终端根据跳频第一步的频域位置以及所述上行信道对应的跳频步长，确定跳频第二步的频域位置；其中，所述跳频第一步的频域位置以及所述跳频第二步的频域位置为用于传输上行信道的频域位置。
这里，终端接收第三控制信令，基于所述第三控制指令确定所述跳频第一步的频域位置。其中，所述第三控制信令为：DCI、或MAC CE。
本发明实施例中，所述第三控制信令与以下至少之一为同一控制信令：所述第一控制信令、所述第二控制信令。
以下结合具体应用示例对本发明实施例的技术方案做进一步详细描述。
应用示例一：
本示例中，针对PUCCH频域，一个带宽分段内采用统一的跳频步长。
图4为本发明实施例的PUCCH频域结构的示意图一，如图4所示，某个带宽分段或某种带宽分段的带宽大小为W，PUCCH频域的跳频步长W H与带宽分段的带宽大小W对应，例如，W H＝W/2。
在一实施方式中，对于采用相同带宽分段的多个终端，均采用相同的W H。例如：带宽分段1的带宽大小为W1，带宽分段2的带宽大小为W2，那么，带宽分段1内的多个终端采用相同的W H＝W1/2，带宽分段2内的多个终端采用相同的W H＝W2/2。
在另一实施方式中，对于采用相同大小的带宽分段的多个终端，均采用相同的W H。例如：带宽分段1和带宽分段2的带宽大小均为W，那么，带宽分段1和带宽分段2内的多个终端均采用相同的W H＝W/2。
应用示例二：
本示例中，针对PUCCH频域，一个带宽分段内采用多种跳频步长。
图5为本发明实施例的PUCCH频域结构的示意图二，如图5所示，某个带宽分段或某种带宽分段的带宽大小为W，PUCCH频域的跳频步长W H与带宽分段的带宽大小W对应。对于采用相同带宽分段或相同大小的带宽分段的多个终端，可以采用不同的W H配置，如终端1的W H＝W/4，终端2的W H＝W/2，也即：终端1和终端2采用不同的n配置，即终端1的n＝4，终端2的n＝2。
