Description

联合信道估计的最大持续时间的上报方法及其装置 技术领域
本公开涉及通信技术领域,尤其涉及一种联合信道估计的最大持续时间的上报方法、装置、通信装置和存储介质。
背景技术
由于覆盖面积直接影响到运营商的QoS(Quality of Service,服务质量)、资本性支出CAPEX(Capital Expenditure)和运营成本OPEX(Operating Expenditure),因此是运营商在部署商用蜂窝无线通信系统时需要重要考虑的一个因素。与4G LTE(Long Term Evolution,长期演进)系统相比,5G(5th Generation Mobile Communication Technology,第五代移动通信技术)NR(New Radio,新空口)系统由于使用的频谱更高,因此路径损耗更大,这对于5G系统的覆盖带来更大的挑战,特别是上行的覆盖能力。
提高上行信道估计性能对于提高上行覆盖具有重要的作用。在通信技术的新一代版本中提出了联合信道估计,以增强物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的覆盖范围。对于联合信道估计,基站和终端(User Equipment,UE)都需要一个时间窗口,UE在该时间窗口期间需要保持功率一致性和相位连续性,以配合基站在该时间窗口执行联合信道估计。联合信道估计性能与时间窗口大小有关,因此如何提高通信系统上行信道估计性能已经成为亟待解决的问题。

为了更好的理解本公开的实施例公开的一种联合信道估计的最大持续时间的上报方法,下面首先对本公开的实施例使用的通信系统进行描述。
请参见图1,图1为本公开的实施例提供的一种通信系统的架构示意图。该通信系统包括但不限于一个终端设备及一个网络侧设备。图1所示的设备数量和形态仅用于举例并不构成对本公开的实施例的限定,实际应用中可以包括两个或两个以上的终端设备及两个或两个以上的网络侧设备。图1所示的通信系统以包括一个终端设备101和一个网络侧设备102为例。
本公开的实施例中的终端设备101是用户侧的一种用于接收或发射信号的实体,如手机。数据接收端也可以称为终端设备(terminal)、用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端设备(mobile terminal,MT)等。数据接收端可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。

下面结合附图对本公开所提供的联合信道估计的最大持续时间的上报方法、通信装置和存储介质进行详细地介绍。
请参见图2,图2是本公开的实施例提供的一种联合信道估计的最大持续时间的上报方法的流程图。需要说明的是,本公开的实施例的联合信道估计的最大持续时间的上报方法可以应用于终端设备。如图2所示,该联合信道估计的最大持续时间的上报方法可以包括但不限于以下步骤。
步骤S201,接收网络侧设备发送的第一消息;其中,该第一消息用于指示终端设备上报联合信道估计的最大持续时间。
在根据本公开的一些实施方式中,终端设备接收网络侧设备发送的第一消息,以上报联合信道估计的最大持续时间,该最大持续时间可理解为终端联合信道估计的时间窗口参考值。作为一种示例,该最大持续时间可以是预先设置的,比如预先设置在终端设备中,可选地,该最大持续时间可以是终端设备基于该终端设备的自身能力而预先设置的,以便终端设备在接收到网络侧设备发送的第一消息时,将预先设置的最大持续时间发送给网络侧设备。此外,应当理解,还可以以其他方式确定最大持续时间,例如网络侧设备配置或根据协议约定等。
需要说明的是,在本公开的一些实施例中,该第一消息可以是由网络侧设备通过广播信道发送的,或者,该第一消息还可以是通过RRC(Radio Resource Control,无线资源控制)信令发送的。
举例而言,当终端设备与网络侧设备进行联合信道估计时,网络侧设备可以通过广播信道或者RRC信令向终端设备发送第一消息,该第一消息用于指示终端设备上报联合信道估计的最大持续时间,以便终端设备接收到网络侧设备发送的第一消息后,向网络侧设备上报联合信道估计的最大持续时间。应当理解,终端设备中可以预先设置一个最大持续时间,也可以预先设置多个最大持续时间。
步骤S202,向网络侧设备发送最大持续时间。
终端设备在接收到网络侧设备发送的第一消息后,向该网络侧设备发送自身能够支持的联合信道估计的最大持续时间。网络侧设备可以基于终端设备上报的联合信道估计的最大持续时间,为该终端设备配置联合信道估计的时间窗口长度,从而使得该终端设备在该时间窗口期间保持功率一致性和相位连续性,以配合网络侧设备在该时间窗口执行联合信道估计。
通过实施本公开的实施例,通过终端设备上报联合信道估计的最大持续时间,以使得网络侧设备将该最大持续时间作为终端联合信道估计的时间窗口参考值,基于该参考值为该终端设备配置联合信道估计重传的时间窗口长度,从而可以提高通信系统上行信道估计性能,并提高上行覆盖。
需要说明的是,在本公开的一些实施例中,网络侧设备可以向终端设备指示自身的解调能力,以使终端设备基于自身能力及网络侧设备的解调能力,上报联合信道估计的最大持续时间。具体地,可以参见图3。
图3是本公开的实施例提供的另一种联合信道估计的最大持续时间的上报方法的流程图。需要说明的是,本公开的实施例的联合信道估计的最大持续时间的上报方法可以应用于终端设备。如图3所示,该联合信道估计的最大持续时间的上报方法可以包括但不限于以下步骤。
步骤S301,接收网络侧设备发送的第一消息,该第一消息用于指示终端设备上报联合信道估计的最大持续时间,并且该第一消息还用于向终端设备指示网络侧设备的解调能力。
在根据本公开的一些实施方式中,终端设备接收网络侧设备发送的第一消息,该第一消息中包括网络侧设备的解调能力的信息,并且该第一消息还指示终端设备上报联合信道估计的最大持续时间,其中,该最大持续时间可理解为终端联合信道估计的时间窗口参考值。作为一种示例,该最大持续时间可以是预先设置的,比如预先设置在终端设备,例如可以是基于该终端设备的自身能力预先为该终端设备设置的,以便终端设备在接收到网络侧设备发送的第一消息时,终端设备可以基于网络侧设备的解调能力将预先设置的最大持续时间发送给网络侧设备。应当理解,终端设备中可以预先设置一个最大持续时间,也可以预先设置多个最大持续时间。
需要说明的是,在本公开的一些实施例中,该第一消息可以是由网络侧设备通过广播信道发送的,或者,还可以是通过RRC信令发送的。
举例而言,终端设备与网络侧设备在进行联合信道估计时,网络侧设备可以通过广播信道或者RRC信令向终端设备发送第一消息,该第一消息用于指示终端设备上报联合信道估计的最大持续时间,以便终端设备接收到网络侧设备发送的第一消息后,根据该网络侧设备的解调能力向该网络侧设备上报联合信道估计的最大持续时间。
步骤S302,根据网络侧设备的解调能力,向网络侧设备发送与解调能力对应的最大持续时间。
举例而言,网络侧设备的解调能力可划分为多个不同等级,网络侧设备可以将当前自身能够支持的解调能力通过第一消息告知终端设备。终端设备在接收到网络侧设备发送的第一消息后,可确定该网络侧设备的具体解调能力等级,并根据该网络侧设备的解调能力等级,发送与该解调能力等级对应的联合信道估计的最大持续时间。
作为一种示例,以网络侧设备的解调能力划分为高等级及低等级两个等级可以为例。其中,网络设备的解调能力信息的长度可以为1bit(比特)。假设解调能力为高等级的网络侧设备对应的联合信道估计的最大持续时间为16slots(时隙),而解调能力为低等级的网络侧设备对应的联合信道估计的最大持续时间为8slots;终端设备能够支持的最大持续时间为8slots及16slots。若终端设备接收到网络侧设备发送的第一消息,该第一消息指示该网络侧设备的解调能力为高等级,则终端设备向该网络侧设备发送最大持续时间为16slots;或者,终端设备接收到网络侧设备发送的消息,该第一消息指示该网络侧设备的解调能力为低等级,则终端设备向该网络侧设备发送最大持续时间为8slots。
作为另一种示例,若终端设备仅能够支持一个最大持续时间,则该终端设备可直接将其能够支持的最大持续时间上报,而无需再根据获取的网络侧设备的解调能力信息选择向网络侧设备发送与该网络设备解调能力对应的最大持续时间。即,若终端设备仅能够支持一个最大持续时间,响应于接收到网络设备发送的要求上报最大持续时间的指示消息,终端设备直接将其能够支持的最大持续时间上报。
通过实施本公开的实施例,通过终端设备基于网络侧设备自身的解调能力,向网络侧设备上报与该解调能力对应的最大持续时间,以使得网络侧设备基于最大持续时间为该终端设备配置联合信道估计重传的时间窗口长度,使得网络侧设备为终端设备配置的时间窗口不仅考虑了该终端设备自身的能力,还考虑了该网络侧设备自身的解调能力,能够同时发挥终端和系统的整体性能,从而可以提高通信系统上行信道估计性能,并提高上行覆盖。
在本公开一些实施例中,终端设备还可接收网络侧设备发送第二消息,该第二消息用于向终端设备指示网络侧设备的解调能力。即,终端设备接收网络侧设备发送的第一信息和第二信息,其中第一信息用于指示终端设备上报联合信道估计的最大持续时间,而第二信息用于向终端设备指示网络侧设备的解调能力。请参见图4,图4是本公开的实施例提供的另一种联合信道估计的最大持续时间的上报方法的流程图。本公开的实施例的联合信道估计的最大持续时间的上报方法可以应用于终端设备。如图4所示,该联合信道估计的最大持续时间的上报方法可以包括但不限于以下步骤。
步骤S401,接收网络侧设备发送的第一消息;第一消息用于指示终端设备上报联合信道估计的最大持续时间。
在本公开的实施例中,步骤S401可分别采用本公开的各实施例中的任一种方式实现,本公开的实施例并不对此作出限定,也不再赘述。
步骤S402,接收网络侧设备发送的第二消息;该第二消息用于向终端设备指示网络侧设备的解调能力。
在根据本公开的一些实施方式中,终端设备还可以接收网络侧设备发送的第二消息,该第二消息可以与第一消息不同,该第二消息中包含该网络侧设备的解调能力信息。然而,应理解,在一些可能的实施方式中,第二消息可以与第一消息相同。
作为一种示例,第二消息可以是RRC信令。或者,该第二消息还可以是由网络侧设备通过广播信道发送给终端设备。
需要说明的是,在本公开的实施例中,步骤S401及步骤S402可以是同时进行的,或者,先执行步骤S401后执行步骤S402;或者,还可以先执行步骤S402后执行步骤S401。此外,应理解,步骤S402可以与步骤S401组合实施,也可以单独实施,本公开对此不做限制。
步骤S403,根据网络侧设备的解调能力,向网络侧设备发送与解调能力对应的最大持续时间。
在本公开的实施例中,步骤S403可分别采用本公开的各实施例中的任一种方式实现,本公开的实施例并不对此作出限定,也不再赘述。
需要说明的是,在本公开的实施例中,可以不执行步骤S401。即,通过预先设置,终端设备可响应于接收到网络侧设备发送的第二消息,向网络侧设备发送最大持续时间,而无需等待接收指示终端设备上报联合信道估计的最大持续时间的第一消息。
通过实施本公开的实施例,终端设备可通过网络侧设备发送的第二消息,获取该网络侧设备的解调能力,并上报与该解调能力对应的最大持续时间,以使得网络侧设备基于最大持续时间为该终端设备配置联合信道估计重传的时间窗口长度,使得网络侧设备为终端设备配置的时间窗口不仅考虑了该终端设备自身的能力,还考虑了该网络侧设备自身的解调能力,能够同时发挥终端和系统的整体性能,从而可以提高通信系统上行信道估计性能,并提高上行覆盖。
在本公开的一些实施例中,网络侧设备不需要向终端设备指示自身的解调能力,而是终端设备将自身所支持的一个或多个最大持续时间上传给网络侧设备,由网络侧设备基于自身的解调能力选择一个最大持续时间,以便基于该选择的最大持续时间为该终端设备配置联合信道估计的时间窗口长度。请参见图5,图5是本公开的实施例提供的另一种联合信道估计的最大持续时间的上报方法的流程图。本公开 的实施例的联合信道估计的最大持续时间的上报方法可以应用于终端设备,本公开的实施例中终端设备可根据自身能力,将自身所支持的一个或多个最大持续时间上报给网络侧设备。如图5所示,该联合信道估计的最大持续时间的上报方法可以包括但不限于以下步骤。
步骤S501,接收网络侧设备发送的第一消息,第一消息用于指示终端设备上报联合信道估计的最大持续时间。
在本公开的实施例中,步骤S501可分别采用本公开的各实施例中的任一种方式实现,本公开的实施例并不对此作出限定,也不再赘述。
步骤S502,向网络侧设备发送一个或多个最大持续时间。
可选的,终端设备在接收到网络侧设备发送的第一消息时,可以将自身支持的一个或多个最大持续时间上报给网络侧设备,以供网络侧设备基于自身解调能力选择一个为该终端设备配置联合信道估计的时间窗口长度。在一种实现方式中,终端设备可以将自身的所有最大持续时间均上报给网络侧设备,以供网络侧设备选择。
举例而言,终端设备仅能够支持一个联合信道估计的最大持续时间,则在接收到网络侧设备发送的第一消息后,将该一个联合信道估计的最大持续时间上报给该网络侧设备,以供该网络侧设备基于该最大持续时间为该终端设备配置联合信道估计的时间窗口长度。或者,终端设备能够支持多个联合信道估计的最大持续时间,则在接收到网络侧设备发送的第一消息后,将支持的多个最大持续时间上报给网络侧设备,以供该网络侧设备基于自身解调能力从该多个最大持续时间选择一个,并基于选择的最大持续时间为该终端设备配置联合信道估计的时间窗口长度。
通过实施本公开的实施例,终端设备可向网络侧设备发送一个或多个最大持续时间,使得网络侧设备基于自身的解调能力从终端设备上报的最大持续时间中选择一个为该终端设备配置联合信道估计重传的时间窗口长度,使得网络侧设备为终端设备配置的时间窗口不仅考虑了该终端设备自身的能力,还考虑了该网络侧设备自身的解调能力,从而能够同时发挥终端和系统的整体性能,从而可以提高通信系统上行信道估计性能,并提高上行覆盖。
请参见图6,图6是本公开的实施例提供的一种联合信道估计的最大持续时间的获取方法的流程图。需要说明的是,本公开的实施例的联合信道估计的最大持续时间的获取方法可以应用于网络侧设备。如图6所示,该联合信道估计的最大持续时间的获取方法可以包括但不限于以下步骤。
步骤S601,向终端设备发送第一消息;该第一消息用于指示终端设备上报联合信道估计的最大持续时间。
举例而言,网络侧设备与终端设备在进行联合信道估计时,网络侧设备可以通过广播信道或者RCC信令向终端设备发送第一消息,该第一消息用于指示终端设备上报联合信道估计的最大持续时间。
其中,在本公开的一些实施例中,该最大持续时间可理解为终端联合信道估计的时间窗口参考值。作为一种示例,该最大持续时间可以是预先设置的,比如预先设置在终端设备,例如可以是基于该终端设备的自身能力预先为该终端设备设置的,以便终端设备在接收到网络侧设备发送的第一消息时,终端设备可以将预先设置的最大持续时间发送给网络侧设备。
步骤S602,接收终端设备发送的最大持续时间。
在一种实现方式中,该方法还包括:根据最大持续时间,为终端设备配置联合信道估计的时间窗口长度。

步骤S801,向终端设备发送第一消息;第一消息用于指示终端设备上报联合信道估计的最大持续时间。
在本公开的实施例中,步骤S801可分别采用本公开的各实施例中的任一种方式实现,本公开的实施例并不对此作出限定,也不再赘述。
步骤S802,向终端设备发送第二消息;第二消息用于向终端设备指示网络侧设备的解调能力。
举例而言,终端设备还可以接收网络侧设备发送的第二消息,该第二消息与第一消息不同,该第二消息中包含该网络侧设备的解调能力信息。
作为一种示例,第二消息可以是RRC信令。或者,该第二消息还可以是由网络侧设备通过广播信道发送给终端设备。
需要说明的是,在本公开的实施例中,步骤S801及步骤S802可以是同时进行的,或者,先执行步骤S801后执行步骤S802;或者,还可以先执行步骤S802后执行步骤S801。
步骤S803,接收终端设备发送的最大持续时间。
在本公开的实施例中,步骤S803可分别采用本公开的各实施例中的任一种方式实现,本公开的实施例并不对此作出限定,也不再赘述。
可选的,在根据本公开一些实施例,该联合信道估计的最大持续时间的获取方法还可以包括以下步骤:根据终端设备上报的最大持续时间,为该终端设备配置联合信道估计的时间窗口长度。其中,该时间窗口长度可以小于或等于最大持续时间。
通过实施本公开的实施例,网络侧设备可通过第二消息向终端设备指示自身的解调能力,使终端设备上报与该解调能力对应的最大持续时间,接收终端设备上报的与该解调能力对应的最大持续时间,并将该最大持续时间作为终端设备联合信道估计的时间窗口参考值,基于该参考值为该终端设备配置联合信道估计重传的时间窗口长度,从而可以提高通信系统上行信道估计性能,并提高上行覆盖。
在本公开的一些实施例中,网络侧设备可接收终端设备发送的一个或多个最大持续时间,并基于自身的解调能力选择一个最大持续时间,以便基于该选择的最大持续时间为该终端设备配置联合信道估计的时间窗口长度。请参见图9,图9为本公开的实施例提供的又一种联合信道估计的最大持续时间的获取方法的流程图。需要说明的是,本公开的实施例的联合信道估计的最大持续时间的获取方法可以应用于网络侧设备。如图9所示,该联合信道估计的最大持续时间的获取方法可以包括但不限于以下步骤。
步骤S901,向终端设备发送第一消息,该第一消息用于指示终端设备上报联合信道估计的最大持续时间。
可选的,终端设备在接收到网络侧设备发送的该第一消息时,可以将自身支持的一个或多个最大持续时间上报给网络侧设备,以供网络侧设备选择。
步骤S902,接收终端设备发送的一个或多个最大持续时间。
需要说明的是,在本公开一些实施例中,网络侧设备在接收到终端设备发送的一个或多个最大持续时间时,可以基于该一个或多个最大持续时间为终端设备配置联合信道估计的时间窗口长度。在一种实现方式中,网络侧设备在接收到终端设备发送的一个最大持续时间时,可以基于该最大持续时间,为终端设备配置联合信道估计的时间窗口长度;或者,网络侧设备在接收到终端设备发送的多个最大持续时间时,可以根据该网络侧设备的解调能力,从该多个最大持续时间中选取一个最大持续时间,并基于选取的最大持续时间为终端设备配置联合信道估计的时间窗口长度。其中,时间窗口长度可以小于或等于用于配置该时间窗口的最大持续时间。
举例而言,网络侧设备在接收到终端设备发送的最大持续时间为一个,且基于该最大持续时间为该终端设备配置联合信道估计的时间窗口长度时,该时间窗口长度可以小于或等于该最大持续时间;或者,网络侧设备在接收到终端设备发送的最大持续时间为多个,且基于自身解调能力选择了一个最大持续时间为该终端设备配置联合信道估计的时间窗口长度时,该时间窗口长度可以小于或等于该选择的最大持续时间。
作为一种示例,假设终端设备仅发送一个8slots的最大持续时间,则网络侧设备可根据该最大持续时间,为该终端设备配置的联合信道估计的时间窗口长度,或者,终端设备同时发送的两个最大持续时间为8slots及16slots,若网络侧设备的解调能力较高,则可选择16slots作为终端联合信道估计的时间窗口参考值,并基于16slots为该终端设备配置联合信道估计的时间窗口长度;或者,若网络侧设备的解调能力较低,则可则选择8slots终端联合信道估计的时间窗口参考值,并基于8slots为该终端设备配置联合信道估计的时间窗口长度。
通过实施本公开的实施例,通过接收终端设备发送的一个或多个最大持续时间,使得网络侧设备基于自身的解调能力从终端设备上报的最大持续时间中选择一个为该终端设备配置联合信道估计重传的时间窗口长度,使得网络侧设备为终端设备配置的时间窗口不仅考虑了该网络侧设备自身的解调能力,还考虑了终端设的能力,能够同时发挥终端和系统的整体性能,从而可以提高通信系统上行信道估计性能,并提高上行覆盖。
在本公开的一些实施例中,网络侧设备可以接收终端设备发送的最大持续时间,并基于该最大持续时间为该终端设备配置联合信道估计的时间窗口长度。具体地,可以参见图10。图10为本公开的实施例提供的又一种联合信道估计的最大持续时间的获取方法的流程图。需要说明的是,本公开的实施例的联合信道估计的最大持续时间的获取方法可以应用于网络侧设备。如图10所示,该联合信道估计的最大持续时间的获取方法可以包括但不限于以下步骤。

举例而言,网络侧设备可以不发送任何消息,而直接接收终端设备发送的最大持续时间。
例如,网络侧设备可以向终端设备发送给第一消息,该第一消息用于指示终端设备上报联合信道估计的最大持续时间。终端设备接收网络侧设备发送的第一消息,以上报联合信道估计的最大持续时间,该最大持续时间可理解为终端联合信道估计的时间窗口参考值。作为一种示例,该最大持续时间可以是预先设置的,比如预先设置在终端设备中,可选地,该最大持续时间可以是终端设备基于该终端设备的自身能力而预先设置的,以便终端设备在接收到网络侧设备发送的第一消息时,将预先设置的最大持续时间发送给网络侧设备。此外,应当理解,还可以以其他方式确定最大持续时间,例如网络侧设备配置或根据协议约定等。
又如,网络侧设备可以向终端设备发送给第一消息,该第一消息用于指示终端设备上报联合信道估计的最大持续时间,且,该第一消息还用于指示该网络侧设备的解调能力。可选的,终端设备接收网络侧设备发送的该第一消息,将与该网络侧设备的解调能力对应的最大持续时间上报给该网络侧设备,使 得网络侧设备可以接收终端设备上报的最大持续时间。
再例如,网络侧设备可以向终端设备发送给第一消息和第二消息,该第一消息用于指示终端设备上报联合信道估计的最大持续时间,该第二消息用于指示该网络侧设备的解调能力。可选的,终端设备接收网络侧设备发送的该第一消息和第二消息,将与该网络侧设备的解调能力对应的最大持续时间上报给该网络侧设备,使得网络侧设备可以接收终端设备上报的最大持续时间。
需要说明的是,在本公开的实施例中,终端设备发送的最大持续时间可以为一个或多个。
步骤S1002,根据最大持续时间,为终端设备配置联合信道估计的时间窗口长度。
作为一种示例,若网络侧设备在接收到终端设备发送的最大持续时间为一个,则该网络侧设备可以基于终端设备上报的联合信道估计的最大持续时间,为该终端设备配置联合信道估计的时间窗口长度,从而使得该终端设备在该时间窗口期间保持功率一致性和相位连续性,以配合网络侧设备在该时间窗口执行联合信道估计
作为另一种示例,若网络侧设备在接收到终端设备发送的最大持续时间为多个,则该网络侧设备可基于自身解调能力,从上述多个最大持续时间中选择一个,并基于选择的最大持续时间,为该终端设备配置联合信道估计的时间窗口长度,从而使得该终端设备在该时间窗口期间保持功率一致性和相位连续性,以配合网络侧设备在该时间窗口执行联合信道估计。
通过实施本公开的实施例,网络侧设备可以基于接收到的终端设备发送的最大持续时间,并考虑该网络侧设备自身的解调能力,为该终端设备配置联合信道估计的时间窗口,从而可以提高通信系统上行信道估计性能,并提高上行覆盖。上述本公开提供的实施例中,分别从终端设备及网络侧设备的角度对本公开的实施例提供的方法进行了介绍。为了实现上述本公开的实施例提供的方法中的各功能,终端设备及网络侧设备可以包括硬件结构、软件模块,以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能可以以硬件结构、软件模块、或者硬件结构加软件模块的方式来执行。
