Description

上行传输方法及装置、存储介质 技术领域
本公开涉及通信领域,尤其涉及上行传输方法及装置、存储介质。
背景技术
在无线通信技术的研究中,卫星通信被认为是未来无线通信技术发展的一个重要方面。卫星通信是指地面上的无线电通信设备利用卫星作为中继而进行的通信。卫星通信系统由卫星部分和地面部分组成。卫星通信的特点是:通信范围大;只要在卫星发射的电波所覆盖的范围内,从任何两点之间都可进行通信;不易受陆地灾害的影响(可靠性高)。卫星通信作为目前地面的蜂窝通信系统的补充,可以有以下的好处:首先,可以实现延伸覆盖,对于目前蜂窝通信系统无法覆盖或是覆盖成本较高的地区,例如海洋,沙漠,偏远山区等,可以通过卫星通信来解决通信的问题。其次,可以进行应急通信,例如在发生灾难如地震等的极端情况下导致蜂窝通信的基础设施不可用的条件下,使用卫星通信可以快速的建立通信连接。另外还可以提供行业应用,例如对于长距离传输的时延敏感业务,可以通过卫星通信的方式来降低业务传输的时延。
可以预见,在未来的无线通信系统中,卫星通信系统和陆地上的蜂窝通信系统会逐步的实现深度的融合,真正的实现万物智联。
在卫星通信系统中,对于上行传输,支持基于segment(段)的传输机制,并且segment的值是可以由基站通知给终端的。如果基站发送给终端的消息中包括多个数值,即多个segment的值,终端需要在多个数值中选择一个数值进行相应传输,但是基站和终端无法对终端选择的数值保持理解一致。而如果基站发送给终端的消息中只包括一个segment的值,显然对于基站的信令开销较大,也会造成终端电量消耗过大。

具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含至少一个相关联的列出项目的任何或所有可能组合。

在介绍本公开提供的上行传输方案之前,先介绍一下卫星通信场景下进行定时调整的方式。
第一种方式,考虑到卫星通信场景下的发送端与接收端存在较长的信号传输距离,导致数据传输需要较长时间。对于存在有上下行关系的传输,相关标准化讨论中确定了引入Koffset(K偏移值)的参数来补偿传输时延。
Koffset参数可以应用在多种操作下,包括但不限于由DCI(Downlink Control Information,下行控制信息)调度的PUSCH(Physical Uplink Share CHannel,物理上行共享信道)、HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)反馈信息的传输等。
第二种方式,可以采用TA(Timing Advance,定时提前)方式,让终端提前发送数据包。
参照图1A所示,基站发送的第n个下行数据包经过一定的传输时延到达终端侧,终端侧发送的第n个上行数据包,相对于接收到的第n个下行数据包存在指定TA值,从而可以让第n个上行数据包到达基站侧的时间点与基站侧发送第n个下行数据包的时间点的误差范围满足预定要求。即在基站侧实现上下行定时对齐。
或者参照图1B所示,在基站侧的上下行定时可以不对齐,基站侧发送的第n个 下行数据包与接收到的第n个上行数据包之间存在指定的帧定时偏移。
上述方式中的任意一种均可以实现定时调整。
在卫星通信系统中由于卫星快速移动,会导致TA的变化较大,终端侧就需要在上行传输时及时基于变化后的TA进行定时调整,导致终端侧能耗较高。
另一方面,对于上行传输,如果基站发送给终端的消息中包括多个segment的值,基站侧和终端侧无法保持对终端所选择的segment的值的理解一致,而如果基站发送给终端的消息中包括一个segment的值,基站需要发送多个消息来通知终端多个segment的值,基站的信令开销较大,也会造成终端电量消耗过大。
为了解决上述技术问题,在卫星通信系统中提高上行传输的可靠性和有效性,本公开提供了以下上行传输方法。下面先从终端侧介绍一下本公开提供的上行传输方法。
本公开实施例提供了一种上行传输方法,参照图2所示,图2是根据一实施例示出的一种上行传输方法流程图,可以由终端执行,该方法可以包括以下步骤:
在步骤201中,接收基站发送的包括多个备选数值的系统消息。
在本公开实施例中,终端还未接入基站,因此可以通过基站发送的系统消息来确定基站配置的多个备选数值,其中,这里的数值是指segment(段)的值。
在一个可能的实现方式中,segment可以是与数据传输对应的参数,例如segment为10毫秒,则终端侧可以在进行数据传输时,将待传输的数据按照每10毫秒为一段进行划分后发送给基站。或者,终端在数据重复传输时,每10毫秒重复传输一次指定数据。
在步骤202中,在所述多个备选数值中,确定第一数值。
在步骤203中,向所述基站发送第一前导码序列。
在本公开实施例中,第一前导码序列的作用除了可以让终端进行随机接入之外,还可以用于指示第一数值。即终端通过第一前导码序列,采用隐式方式将终端在多个备选数值中确定的第一数值告知给基站,以便基站和终端对数值保持理解一致,即对segment的值的理解一致。
上述实施例中,可以在卫星通信系统中,有效确保基站和终端对于上行传输的数值理解一致,提高了上行传输的可靠性和有效性。
在一些可选实施例中,参照图3所示,图3是根据一实施例示出的一种上行传输方法流程图,可以由终端执行,该方法可以包括以下步骤:
在步骤301中,接收基站发送的包括多个备选数值的系统消息。
在本公开实施例中,终端还未接入基站,因此可以通过基站发送的系统消息来确定基站配置的多个备选数值。
终端接收到的系统消息中除了包括上述的多个备选数值之外,还可以包括第一指示信息。其中,第一指示信息用于指示所述第一数值的关联值。
