Description

系统信息传输方法和装置 技术领域
本公开涉及通信技术领域，尤其涉及一种系统信息传输方法和装置。
背景技术
在目前的3GPP(third generation partnership project，第三代合作伙伴计划)标准化中，提出了新的终端类型叫做Reduced capability UE(user equipment，终端)或简称为NR-lite或Redcap终端，在一些场景下也称为能力缩减UE。
随着Redcap终端引入到NR(new radio，新空口)系统中，会针对Redcap终端配置单独的initial DL BWP(initial downlink bandwidth partinitial，初始下行带宽部分)和单独的initial UL BWP(initial uplink bandwidth partinitial，初始上行带宽部分)，而网络侧设备中原本还具有的一个initial DL BWP和一个initial UL BWP，这将会导致网络侧设备具有多个initial DL BWP和多个initial UL BWP，此时，如何进行按需on-demand SI(system information，系统信息)的传输是亟需解决的问题。

具体实施方式
为了更好的理解本公开实施例公开的一种系统信息传输方法，下面首先对本公开实施例适用的通信系统进行描述。
请参见图1，图1为本公开实施例提供的一种通信系统10的架构示意图。该通信系统10可包括但不限于一个网络侧设备和一个终端，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实施例的限定，实际应用中可以包括两个或两个以上的网络侧设备，两个或两个以上的终端。图1所示的通信系统10以包括一个网络侧设备101和一个终端102为例。
需要说明的是，本公开实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。
本公开实施例中的网络侧设备101是网络侧的一种用于发射或接收信号的实体。例如，网络侧设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络侧设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的网络侧设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络侧设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端102是用户侧的一种用于接收或发射信号的实体，如手机。终端也可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终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、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本公开的实施例对终端所采用的具体技术和具体设备形态不做限定。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
在LTE 4G系统中，为了支持物联网业务提出了MTC(machine type communication，机器型通信)，NB-IoT(narrow band-internet of things，窄带物联网)两大技术。这两大技术主要针对的是低速率，高时延等场景，比如抄表，环境监测等场景。
其中，NB-IoT目前最大只能支持几百k的速率，而MTC目前最大只能支持几M的速率。但同时 一方面，随着物联网业务的不断发展，比如视频监控，智能家居，可穿戴设备和工业传感监测等业务的普及，这些业务通常要求几十到100M的速率，并且对时延也有相对较高的要求，但是LTE中的MTC，NB-IoT技术很难满足要求。基于此，提出了在5G NR(新空口)中再设计一种新的终端用以来覆盖这种中端物联网设备的要求。在目前的3GPP(the 3rd generation partnership project，第三代合作伙伴项目)标准化中，这种新的终端类型叫做轻量化终端(Reduced capability，Redcap终端)或者简称为RedCap(轻量空口)。另一方面，同LTE中的物联网设备类似，基于5G系统中的RedCap通常需要满足如下要求：低造价，低复杂度；一定程度的覆盖增强；功率节省。
然而，目前的NR(新空口)是针对高速率低时延等高端终端设计的，当前的设计无法满足RedCap的上述要求。因此需要对目前的NR系统进行改造用以满足RedCap的要求。比如，为了满足低造价，低复杂度等要求，可以限制NR-IoT的RF(radio frequency，射频)带宽，比如限制到5M Hz或者10M Hz,或者限制RedCap的缓冲的大小，进而限制每次接收传输块的大小等等。针对功率节省，可能的优化方向是简化通信流程，减少RedCap终端检测下行控制信道的次数等。
相关技术中，NR系统中的按需on-demand SI的传输，在当前的系统信息传输中，有部分的系统信息可以设置为广播模式或者非广播模式，其中非广播模式的系统信息为on-demand SI。相关技术中，on-demand SI有如下两种申请方式：
方式一：网络设备会配置专用的PRACH(physical randomaccess channel，物理随机接入信道)资源，终端会发送特定的签到码preamble，从而获取所需的系统信息。
方式二：网络侧设备不会配置专用的PRACH资源，终端在第三消息(Msg3)发送on-demand SI的请求。
然而，随着Redcap终端引入到NR系统中，针对Redcap终端配置单独的initial DL BWP和单独的initial UL BWP，而网络侧设备中原本还具有的一个initial DL BWP和一个initial UL BWP，这将会导致网络侧设备具有多个initial DL BWP和多个initial UL BWP，此时，如何进行按需on-demand SI(system information，系统信息)的传输是亟需解决的问题。
基于此，本公开实施例中提供一种系统信息传输方法，以至少解决相关技术中针对Redcap终端配置单独的initial DL/UL BWP，网络侧设备中会存在多个initial DL/UL BWP，无法进行按需on-demand SI的传输的技术问题。
下面结合附图对本公开所提供的系统信息传输方法和装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种系统信息传输方法的流程图。
如图2所示，该方法由网络侧设备执行，该方法可以包括但不限于如下步骤：
S21：根据接收到的终端发送的系统信息SI请求消息对应的配置，在所述配置对应的第一初始下行带宽部分或者第二初始下行带宽部分上发送被请求SI。
在一些可能的实现方式中，终端包括第一类终端和第二类终端；第一类终端可以为Redcap终端，第二类终端可以为普通的终端，第一类终端的终端能力与第二类终端的终端能力不同。
其中，第一初始下行带宽部分可以由第一类终端和第二类终端使用，第二初始下行带宽部分仅能第一类终端使用。
在本公开实施例中，第一类终端发送的SI请求消息对应的配置与第二类终端发送的SI请求消息对应的配置不同，因此网络侧设备能够根据接收到的SI请求消息对应的配置，确定发送该SI请求消息的终端的类型，以及确定应该在第一初始下行带宽部分上发送被请求SI还是应该在第二初始下行带宽部 分上发送被请求SI的结果，从而网络侧设备可以根据终端的类型，以及确定的应该在第一初始下行带宽部分上发送被请求SI或者确定的应该在第二初始下行带宽部分上发送被请求SI的结果，在对应的第一初始下行带宽部分或者第二初始下行带宽部分上发送被请求SI。
示例性实施例中，在网络侧设备根据接收到的终端发送的SI请求消息对应的配置，确定终端的类型为第一类终端，以及确定应该在第一初始下行带宽部分上发送被请求SI的情况下，网络侧设备在第一初始下行带宽部分上向第一类终端发送被请求SI。
另一示例性实施例中，在网络侧设备根据接收到的终端发送的SI请求消息对应的配置，确定终端的类型为第一类终端，以及确定应该在第二初始下行带宽部分上发送被请求SI的情况下，网络侧设备在第二初始下行带宽部分上向第一类终端发送被请求SI，从而，在确定应该在第二初始下行带宽部分上发送被请求SI的情况下，网络侧设备在第二初始下行带宽部分上发送被请求SI，网络侧设备无需分别在第一初始下行带宽部分和第二初始下行带宽部分传输被请求SI，能够提高网络侧设备的传输效率；并且第一类终端可以驻留在第二初始下行带宽部分，在第二初始下行带宽部分上接收被请求SI，避免了第一类终端在第一初始下行带宽部分和第二初始下行部分来回切换，可以节省第一类终端的功耗。
又一示例性实施例中，在网络侧设备根据接收到的终端发送的SI请求消息对应的配置，确定终端的类型为第二类终端，以及确定应该在第一初始下行带宽部分上发送被请求SI的情况下，网络侧设备在第一初始下行带宽部分上向第二类终端发送被请求SI。

S151：接收网络侧设备的第二配置信息；其中，第二配置信息包括第一SI调度信息，第一SI调度信息应用于配置被请求SI仅在第一初始下行带宽部分上的传输。
在本公开的实施例中，网络侧设备向终端发送包括第一SI调度信息的第二配置信息，第一SI调度信息指示终端仅能在第一初始下行带宽上接收被请求SI，响应于终端发送的SI请求消息，网络侧设备在第一初始下行带宽上向终端发送被请求SI，其中，终端包括第一类终端和第二类终端。
在一些可能的实现方式中，终端包括第一类终端和第二类终端；第一类终端可以为Redcap终端，第二类终端可以为普通的终端，第一类终端的终端能力与第二类终端的终端能力不同。
在本公开的实施例中，第一SI调度信息应用于配置被请求SI仅在第一初始下行带宽部分上的传输，可以理解的是，在此情况下，不论终端的类型为第一类终端还是第二类终端，都仅能在第一初始下行带宽部分上接收被请求SI。
在本公开的实施例中，第一配置信息可以为SIB1消息，系统信息块(system information block，SIB)。
上述实施例中，第二配置信息包括第一SI调度信息，网络侧设备将包含第一SI调度信息的第二配置信息发送至终端，以告知第一类终端在第一初始下行带宽部分上接收被请求SI。
当然，第一类终端确定第一SI调度信息的方式可以有很多种，上述实施例中是以网络侧设备通过发送第二配置信息的方式使得第一类终端确定第一SI调度信息；但是本领域内技术人员可以理解，第一类终端还可以通过其他方式确定第一SI调度信息，例如通过通信协议确定，或是从其他设备接收到第一SI调度信息的配置信息，或是预存在第一类终端中，本公开实施例并不对此作出限定。需要说明的是，S151可以单独被实施，也可以结合本公开实施例中的任何一个其他步骤一起被实施，例如结合本公开实施例中的S101和/或S111和/或S121和/或S131和/或S141一起被实施，本公开实施例并不对此做出限定。
请参见图16，图16是本公开实施例提供的又一种系统信息传输方法的流程图。
如图16所示，该方法由第一类终端执行，该方法可以包括但不限于如下步骤：
S161：接收网络侧设备的第二配置信息；其中，第二配置信息包括第二SI调度信息，第二SI调度信息应用于配置第二类终端的被请求SI在第一初始下行带宽部分传输，以及第一类终端的被请求SI在第二初始下行带宽部分上传输。
在一些可能的实现方式中，终端包括第一类终端和第二类终端；第一类终端可以为Redcap终端，第二类终端可以为普通的终端，第一类终端的终端能力与第二类终端的终端能力不同。
在本公开的实施例中，网络侧设备向终端发送包括第二SI调度信息的第二配置信息，第二SI调度信息指示第二类终端的被请求SI在第一初始下行带宽部分传输，以及第一类终端的被请求SI在第二初始下行带宽部分上传输，响应于第一类终端发送的SI请求消息，网络侧设备在第二初始下行带宽上发送被请求SI，响应于第二类终端发送的SI请求消息，网络侧设备在第一初始下行带宽上发送被请求SI。
在本公开的实施例中，向第一类终端发送第二配置信息，以告知第一类终端在第二初始带宽部分接收被请求SI；向第二类终端发送第二配置信息，以告知第二类终端在第一初始带宽部分接收被请求SI。
当然，第一类终端和第二类终端确定第二SI调度信息的方式可以有很多种，上述实施例中是以网络侧设备通过发送第二配置信息的方式使得第一类终端和第二类终端确定第二SI调度信息；但是本领域内技术人员可以理解，第一类终端和第二类终端还可以通过其他方式确定第二SI调度信息，例如通过通信协议确定，或是从其他设备接收到第二SI调度信息的配置信息，或是预存在第一类终端和第二类终端中，本公开实施例并不对此作出限定。
在本公开的实施例中，在网络侧设备接收终端发送的SI请求信息之后，确定终端的类型为第一类终端的情况下，在第二初始下行带宽部分上向第一类终端发送被请求SI。由此，网络侧设备可以仅在第二初始下行带宽部分传输被请求SI，避免了网络侧设备需要分别在第一初始下行带宽部分和第二初始下行带宽部分传输被请求SI，能够提高网络侧设备的传输效率，且第一类终端驻留在第二初始下行带宽部分，可以在第二初始下行带宽部分上接收被请求SI，避免了第一类终端在第一初始下行带宽部分和第二初始下行部分来回切换，可以节省第一类终端的功耗。
需要说明的是，S161可以单独被实施，也可以结合本公开实施例中的任何一个其他步骤一起被实施，例如结合本公开实施例中的S101和/或S111和/或S121和/或S131和/或S141和/或S151一起被实施，本公开实施例并不对此做出限定。
请参见图17，图17是本公开实施例提供的又一种系统信息传输方法的流程图。
如图17所示，该方法由第一类终端执行，该方法可以包括但不限于如下步骤：
S171：接收网络侧设备的随机接入响应RAR消息；其中，在第二初始下行带宽部分上接收RAR消息。
需要说明的是，步骤S171可以单独被实施，也可以结合本公开实施例中的任何一个其他步骤一起被实施，例如结合本公开实施例中的步骤S101和/或步骤S111和/或S121和/或S131和/或S141和/或S151和/或S161一起被实施，本公开实施例并不对此做出限定。
在本公开的实施例中，网络侧设备接收第一类终端在第一特定PRACH资源上发送的SI请求消息，或者，在接收到第一类终端在第二初始上行带宽部分上发送的随机接入，向第一类终端发送RAR消息，以告知第一类终端可以接入网络侧设备。
