Abstract

本申请提出资源指示方法、数据接收方法及装置。所述方法包括向终端发送第一指示信令；其中，所述第一指示信令包含预留的时域资源信息,用于指示预留的时域资源不能用于传输。

Description

资源指示方法、数据接收方法及装置
本申请要求在2019年08月07日提交中国专利局、申请号为201910733945.7的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，例如涉及资源指示方法、数据接收方法及装置。
背景技术
机器类型通信(Machine Type Communications，简称为MTC)，又称机器到机器(Machine to Machine，简称为M2M)。机器类型通信和窄带物联网(NB-IoT，Narrow Band Internet of Things)是物联网的主要应用形式。相关技术中基于LTE(Long Term Evolution，长期演进)/LTE-A(LTE-Advanced，演进LTE)的MTC终端，通常和传统LTE/LTE-A终端部署在同一个系统带宽下。NB-IoT终端采用带内部署(inband)和保护带部署(Guard band)方式，也和传统LTE/LTE-A终端部署在同一个系统带宽下。随着传统LTE/LTE-A终端退出市场，相关技术中的LTE频谱将被第五代移动通信技术(5th generation mobile networks，5G)新空口系统(NR，New Radio)所取代。
在共存系统带宽有限的情况下，LTE-MTC/NB-IoT和NR系统不能在共存系统带宽内各自享有独立的频域区域，这时，LTE-MTC/NB-IoT和NR系统将共享同一频域资源。由于基于LTE/LTE-A的MTC终端以及NB-IoT终端至少是十年的使用寿命，基于LTE/LTE-A的MTC系统(简称LTE-MTC系统)或NB-IoT系统和NR系统需要较长时间共存。如何在共存系统带宽有限的情况下保证系统共存时的性能，是需要解决的问题。

具体实施方式
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。
如图1所示，本申请实施例提供的资源指示方法包括：
步骤S11：向终端发送第一指示信令。
其中，所述第一指示信令包含预留时域资源信息，用于指示第一时域资源不能用于传输。
在本申请实施例中，所述指示信令用于配置预留的时域资源和/或频域资源。
在本申请实施例中，所述时域资源用于在第一系统中传输第二系统的目标数据；所述第一系统和第二系统为共享同一频谱资源的系统。
在本申请实施例中，第一系统可以为LTE-MTC系统或者NB-IoT系统。第 二系统可以为NR系统。
在本申请实施例中，当第二系统为NR系统时，第一时域资源可用于传输NR系统的同步信号块(Synchronization Signal Block，SSB)和/或公共控制信道块(Control-Resource Set 0，CORESET 0)。
本申请实施例通过信令指示第一时域资源不能用于传输，从而可以将第一时域资源预留给另一系统，保证两个系统共享同一频谱资源时重要数据的传输。
在一种实施方式中，可以通过配置时域预留周期的方式配置预留的时域资源，进一步通过时域预留位图或者时域预留指示值，指示时域预留周期中进一步的时域资源配置状况。
在一种实施方式中，时域预留周期可以为任意时间值，例如，时域预留周期为下述中的一个：5ms、10ms、20ms、40ms、80ms和160ms。在本申请实施例中，当第二系统为NR系统时，目标数据可以为NR系统的同步信号块(Synchronization Signal Block，SSB)和/或公共控制信道块(CORESET 0)。
如图2、图3所示的示例中，半个无线帧(frame)包括五个NR Slot和10个LTE slot，半个无线帧内，对于共存时的15kHz子载波间隔配置，SSB最多发送四次，每次占用4个符号位。CORESET 0也发送4次，每次占据2个符号位。对于目标数据为SSB的情况，在半个子帧的前四个LTE时隙中分别为SSB预留四个符号位。对于目标数据为SSB和CORESET 0的情况，在LTE slot0和LTE slot2中分别预留前两个符号位给CORESET 0，在LTE slot1和LTE slot3中分别预留第2、3、4、5个符号位给SSB，在LTE slot4和LTE slot6中分别预留前2个符号为给CORESET 0。

在一种实施方式中，所述时域预留周期信息和时域偏置信息通过6比特联合指示。

在其它实施例中，指示值还可以是其它长度，例如，通过4比特、5比特、6比特等大于3的比特值指示时域预留周期，通过6比特、7比特、8比特等大于5的比特值指示时域偏置。也可以通过大于6的比特值联合指示时域预留周期和时域偏置。
