Description

一种部分带宽确定方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种部分带宽确定方法、装置及存储介质。
背景技术
在长期演进(Long Term Evolution，LTE)4G系统中，为了支持物联网业务，提出了机器类通信(Machine Type Communication，MTC)，窄带物联网(Narrow band Internet of thing，NB-IoT)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。NB-IoT目前最大只能支持几百k的速率，MTC目前最大只能支持几M的速率。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，同时对时延也有相对较高的要求，因此相关技术中的MTC还让NB-IoT技术很难满足要求。故，提出了在5G新空口(New Radio，NR)中再设计一种新的终端类型用以来覆盖中端物联网设备的要求。在目前的3GPP标准化中，这种新的终端类型叫做低能力终端，有时也称为Reduced capability UE，或者称为Redcap终端，或者简称为NR-lite。
相关技术中，考虑Redcap终端的时分复用的中心频点分布(TDD center frequency-alignment)以及同步广播信号块(Synchronization Signal and PBCH block，SSB)开销(overhead)等因素，相关技术中，新引入了一种下行初始部分带宽(Initial DL BWP)。该新引入的Initial DL BWP，专用于进行随机接入(Random Access Channel，RACH)，并且此Initial DL BWP中可以不包含SSB等。
基于上述专用于随机接入的Initial DL BWP，Redcap终端可以完成随机接入。但是Redcap终端基于该专用于随机接入的Initial DL BWP完成随机接入后，终端应该监测哪个BWP，是一个亟待解决的问题。

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公开相一致的所有实施方式。
本公开实施例提供的初始部分带宽确定方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括终端和网络设备。终端和网络设备之间通过无线资源进行信息的发送与接收。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网络设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数量和终端数量不做限 定。
进一步可以理解的是，本公开实施例的无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网络设备。该无线接入网络设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开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。
本公开实施例涉及的终端可以理解为是在5G NR中设计的新的类型终端：低能力终端。低能力终端有时也称为Reduced capability UE，或者称为Redcap终端，或者简称为NR-lite。本公开实施例中，将该新的终端称为Redcap终端。
同长期演进(Long Term Evolution，LTE)中的物联网(Internet of Thing，IoT)设备类似，5G NR-lite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
由于目前的NR系统是针对高速率低时延等高端终端设计的，因此当前的设计无法满足NR-lite的上述要求。因此需要对目前的NR系统进行改造用以满足NR-lite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的射频(Radio Frequency，RF)带宽，比如限制到5M Hz或者10M Hz,或者限制NR-lite的缓存(buffer)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NR-lite终端检测下行控制信道的次数等。
相关技术中，为了更好地支持不能处理整个载波带宽的终端以及接收带宽自适应，NR标准定义了BWP。在NR系统中，为空闲态/非激活态的终端配置Initial BWP。终端从连接态进入到非激活态时，将驻留(camp on)在Initial BWP，并监测Initial BWP。相关技术中，考虑Redcap终端的TDD center frequency-alignment以及SSB overhead等因素，为Redcap终端也定义了专用于Redcap终端进行随机接入的Initial DL BWP。该专用于随机接入的Initial DL BWP不包括同步广播信号块(Synchronization Signal and PBCH block，SSB)等。
然而，终端基于专用于随机接入的Initial DL BWP完成随机接入后，应该监测哪个BWP是目前还在讨论的问题。其中，一种方法是在随机接入的消息4(Msg.4)中给终端配置一个激活BWP(active BWP)。但是这种方法会导致比较多的开销。并且，这种方法会造成Msg.4有更大的传输块大小(transmission block size，TBS)，造成initial DL BWP的拥塞。
本公开实施例提供一种BWP的确定方法，以确定终端完成随机接入后监测的BWP。
一种实施方式中，本公开实施例可以确定不同于终端进行随机接入时所用BWP的BWP，作为终端随机接入后监测的BWP。
本公开实施例中为描述方便，将用于终端完成随机接入后监测的BWP称为第一BWP，将终端进行随机接入使用的BWP称为第二BWP。

图3是根据一示例性实施例示出的一种BWP确定方法的流程图，该BWP确定方法可以单独被执行，也可以结合本公开其他实施例一起被执行。如图3所示，BWP确定方法用于终端中，包括以下步骤。
在步骤S21中，确定终端使用第二BWP完成随机接入。
其中，终端使用第二BWP进行随机接入过程与相关技术中随机接入过程类似，例如可以是进行四步随机接入，也可以是进行两步随机接入。
在步骤S22中，从第二BWP切换至第一BWP进行监测。
本公开实施例中，由于终端已确定了进行随机接入后需要监测的第一BWP，故在终端完成随机接入后，可以自动切换至第一BWP进行监测。
本公开实施例以下将对终端确定第一BWP的过程进行说明。
一种实施方式中，终端确定第一BWP，基于网络设备的配置确定。
一示例中，终端可以基于网络设备配置的信令确定第一BWP。网络设备发送用于配置第一BWP的信令，终端接收网络设备发送的信令，基于该信令确定第一BWP。
本公开实施例一种实施方式中，网络设备可以配置终端的专属信令，即网络设备将配置有第一BWP的信令发送给该信令专属的终端。在终端的专属信令中可包括终端后续需要监测的BWP(第一BWP)。当然该专属信令中也可以不包括终端后续需要监测的BWP。
一种实施方式中，本公开实施例中在终端的专属信令配置有终端后续需要监测的第一BWP的情况下，终端确定后续需要监测的BWP为第一BWP。
图4A是根据一示例性实施例示出的一种BWP确定方法的流程图，该BWP确定方法可以单独被执行，也可以结合本公开其他实施例一起被执行。如图4A所示，BWP确定方法用于终端中，包括以下步骤。
在步骤S31中，获取终端的专属信令。
本公开实施例中，终端的专属信令包含用于配置终端后续需要监测的第一BWP。
在步骤S32中，基于终端的专属信令，确定第一BWP。
进一步的，本公开实施例中，终端确定完成随机接入后，可切换至专属信令中包括的第一BWP进行监测。
图4B是根据一示例性实施例示出的一种BWP确定方法的流程图，该BWP确定方法可以单独被执行，也可以结合本公开其他实施例一起被执行。如图4B所示，BWP确定方法用于终端中，包括以下步骤。
在步骤S33中，响应于终端完成随机接入且终端的专属信令中配置有终端后续需要监测的第一BWP，切换至第一BWP进行监测。
本公开实施例中，在终端的专属信令中配置终端后续需要监测的第一BWP情况下，切换至第一BWP进行监测，能够避免完成随机接入后监测的BWP不明确的问题。
本公开实施例提供的BWP确定方法中，用于随机接入后监测的第一BWP，可以在广播信令中配置。
另一示例中，网络设备可以配置包括第一BWP的广播信令，该包括第一BWP的广播信令可以是终端间共享的，即网络设备可以将包括第一BWP的广播信令发送给多个终端，例如可以是同一类型的所有终端。本公开实施例中将共享第一BWP广播信令的终端称为第一类型终端。其中，该第一类型终端可以是Redcap终端。
图5A是根据一示例性实施例示出的一种BWP确定方法的流程图，该BWP确定方法可以单独被执行，也可以结合本公开其他实施例一起被执行。如图5所示，BWP确定方法用于终端中，包括以下步骤。
在步骤S41中，获取第一类型终端共享的广播信令，广播信令用于配置第一BWP。
在步骤S42中，基于广播信令，确定第一BWP。
其中，本公开实施例提供的BWP确定方法，第一类型终端可以是适用于Redcap终端的带宽能力，使得Redcap终端能够在适用于Redcap终端的第一BWP中进行通信。第一类型终端的通信能力低于能力阈值。其中，终端的通信能力包括收发带宽、收发天线数量、传输块的最大比特数、以及处理时间延迟中的一项或多项。
进一步的，本公开实施例中，终端确定完成随机接入后，可切换至专属信令中包括的第一BWP进行监测。
图5B是根据一示例性实施例示出的一种BWP确定方法的流程图，该BWP确定方法可以单独被执行，也可以结合本公开其他实施例一起被执行。如图5B所示，BWP确定方法用于终端中，包括以下步骤。
在步骤S43中，响应于终端完成随机接入且第一类型终端共享的广播信令中配置有终端后续需要监测的第一BWP，切换至第一BWP进行监测。
本公开实施例中，在广播信令中配置终端后续需要监测的第一BWP情况下，切换至第一BWP进行监测，能够避免完成随机接入后监测的BWP不明确的问题。
另一种实施方式中，终端可以基于预定义条件，确定后续切换至第一BWP进行监测。
其中，预定义条件包括如下条件中的至少一个：第二BWP为专用于随机接入的BWP。终端的专属信令中未配置终端的默认BWP(default BWP)。以下将终端使用的默认BWP称为第三BWP。
响应于满足预定义条件，终端期待切换至第一BWP上进行监测。响应于不满足预定义条件，终端切换至第三BWP进行检测。
其中，本公开实施例提供的BWP确定方法，可以基于预定义，确定终端完成随机接入后监测的第一BWP，可以理解为是基于配置信息，确定终端完成随机接入后是否切换至第一BWP进行监测。其中，配置信息中包括有用于指示第一BWP的信息域。
一种实施方式中，指示第一BWP的信息域可以使能(enable)或者去使能(disable)第一BWP。其中，使能第一BWP的情况下，终端可以在完成随机接入后切换至第一BWP进行监测。去使能第一BWP的情况下，终端在完成随机接入后将不能切换至第一BWP进行监测。
进一步可以理解的是，本公开实施例中，可以是在网络设备未配置第一BWP的情况下，终端基于预定义条件确定后续需要监测的BWP。一示例中，若终端的专属信令中未配置第一BWP，终端可以在完成随机接入后切换至终端使用的默认BWP上进行监测。或者若第一类型终端共享的广播信令中未配置第一BWP，终端可以在完成随机接入后切换至终端使用的默认BWP上进行监测。
图6是根据一示例性实施例示出的一种BWP确定方法的流程图，该BWP确定方法可以单独被执行，也可以结合本公开其他实施例一起被执行。如图6所示，BWP确定方法用于终端中，包括以下步骤。
在步骤S51中，获取网络设备发送的指令。
其中，网络设备发送的指令可以是终端的专属信令，也可以是终端间共享的广播信令。
在步骤S52中，响应于获取到的信令未配置第一BWP，确定第三BWP。
在步骤S53中，响应于终端完成随机接入，切换至第三BWP进行监测。
其中，第三BWP为终端使用的默认BWP。终端使用的默认BWP可基于公共控制资源集(Control resource set，CORESET)确定。例如，第三BWP可以是CORESET#0中定义的BWP。
本公开实施例提供的一种实施方式中，第一BWP中包括SSB。第一BWP中包含的 SSB可以是小区级别的SSB(cell-defined SSB)或者也可以是非小区级别的SSB(non-cell-defined SSB)。
进一步的，在R15/R16中，当终端配置了动态BWP切换时，指示需要切换的BWP，以下称为第四BWP。相关技术中为切换至第四BWP的定时器(timer)。在timer结束后，终端会回退至default BWP。Default BWP可以是网络配置的，如果网络没有配置，在缺省的情况下终端会fallback到initial BWP上。但是对于initial BWP为专用于随机接入的BWP的场景时，由于此initial BWP只用于随机接入，不适用于连接态。
应用本公开实施例提供的BWP确定方法，响应于终端确定了第一BWP，终端监测网络动态指示的第四BWP对应的定时器超时，回退至第一BWP。
图7是根据一示例性实施例示出的一种BWP确定方法的流程图，该BWP确定方法可以单独被执行，也可以结合本公开其他实施例一起被执行。如图7所示，BWP确定方法用于终端中，包括以下步骤。
在步骤S61中，确定第一BWP。
在步骤S62中，终端监测网络动态指示的第四BWP对应的定时器超时，回退至第一BWP。
其中，第四BWP对应的定时器可以理解为是网络为终端配置动态BWP切换时所配置的定时器。
本公开实施例提供的BWP确定方法，终端确定第一BWP，第一BWP不同于随机接入时使用的BWP。在配置有专用于随机接入的第二BWP的情况下，终端监测网络动态指示的第四BWP对应的定时器超时，回退至第一BWP，能够解决相关技术中动态进行BWP切换时对应定时器超时的情况下，默认BWP不明确的问题。
可以理解的是，本公开实施例提供的上述BWP确定方法可以适用于Redcap终端。
当给RedCap终端配置了一个专用于随机接入的BWP(Initial DL BWP only for RACH)的情况下，可以基于本公开实施例提供的确定完成随机接入后监测的BWP的方法，确定完成随机接入后监测的BWP。并且，基于本公开实施例提供的确定BWP的方法，明确了终端的行为，例如，在动态进行BWP切换时对应定时器超时的情况下可以回退至第一BWP。
基于相同的构思，本公开实施例还提供一种应用于网络设备的BWP确定方法。
图8是根据一示例性实施例示出的一种BWP确定方法的流程图，该BWP确定方法可以单独被执行，也可以结合本公开其他实施例一起被执行。如图8所示，BWP确定方法用于网络设备中，包括以下步骤。
在步骤S71中，发送指令，指令用于配置终端后续需要监测的第一BWP。
其中，第一BWP为终端完成随机接入后监测的BWP；第一BWP与第二BWP不同，第二BWP为终端进行随机接入时使用的BWP。
一种实施方式中，网络设备发送的指令包括终端的专属信令，终端的专属信令中配置终端后续需要监测的第一BWP。
另一种实施方式中，网络设备发的指令包括第一类型终端共享的广播信令，广播信令用于配置第一BWP，第一类型终端的通信能力低于能力阈值，通信能力包括收发带宽、收发天线数量、传输块的最大比特数、以及处理时间延迟中的一项或多项。
本公开实施例中，网络设备还可以向终端发送配置信息，配置信息中包括用于指示使能或去使能第一BWP的信息域。其中，使能第一BWP的情况下，终端可以在完成随机接入后切换至第一BWP进行监测。去使能第一BWP的情况下，终端在完成随机接入后将不能切换至第一BWP进行监测。
一种实施方式中，网络设备可以在确定满足预定义条件的情况下，在配置信息中包括用于指示使能第一BWP的信息域。其中，预定义条件包括如下条件中的至少一个：第二BWP为专用于随机接入的BWP：终端的专属信令中未配置终端的默认BWP。
可以理解的是，本公开实施例中，网络设备可以基于第一BWP，与终端进行通信。例如，网络设备可以明确终端完成随机接入后监测的第一BWP，进而基于该第一BWP对终端进行后续的通信调度。
本公开实施例提供的BWP确定方法，网络设备对终端进行随机接入后使用的第一BWP进行配置，使得终端能够明确随机接入后使用的BWP。
可以理解的是，本公开实施例提供的BWP确定方法可以适用于终端与网络设备交互实现BWP确定的实施方案。
需要说明的是，本领域内技术人员可以理解，本公开实施例上述涉及的各种实施方式/实施例中可以配合前述的实施例使用，也可以是独立使用。无论是单独使用还是配合前述的实施例一起使用，其实现原理类似。本公开实施中，部分实施例中是以一起使用的实施方式进行说明的。当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
基于相同的构思，本公开实施例还提供一种BWP确定装置。
