Description

频分复用方法、频分复用装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及频分复用方法、频分复用装置及存储介质。
背景技术
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，因此相关技术中的机器类通信(Machine Type Communication，MTC)，窄带物联网(Narrow band Internet of thing，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(Reduced capability UE)或者简称为NR-lite。
相关技术中，在相同的时间单元内，多个物理随机接入信道(Physical Random Access Channel，PRACH)信道可以进行频分复用(Frequency Division Multiplexing，FDM)。在不同的PRACH子载波间隔(subcarrier spacing，SCS)和物理上行共享信道(physical uplink shared channel，PUSCH)子载波间隔组合下，每个PRACH信道占用不同的频域宽度。在NR系统中，可以支持FDM因子为1，2，4，8个PRACH信道进行FDM复用。在不同的FDM因子下，对应用各自的频域带宽。
针对Reduced capability UE，接收频域带宽会受限。比如在传输模式(Frame Relay，FR)1下的最大接收带宽是20MHz，在FR2下最大接收带宽可能是50MHz或者100MHz。对于接收频域带宽受限的Reduced capability UE而言，传统PRACH FDM对应的频域带宽可能会超过受限的最大频域带宽。

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。相反，它们仅是与如所附权 利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的接入方法可应用于图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中设计的新的终端类型：Reduced capability UE或者简称为NR-lite。本公开实施例中，将该新的终端称为5G NR-lite。
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，在相同的时间单元内，多个PRACH信道可以进行FDM。终端根据测量的SSB选择对应的PRACH信道进行选择。在NR系统中，可以支持FDM因子为1，2，4，8个PRACH信道进行FDM复用。在不同的FDM因子下，对应用各自的频域宽度。在不同的FDM因子下，所需的频带带宽如下表1所示。
表1

Figure PCTCN2020102785-appb-000002
其中，在不同的PRACH子载波间隔和物理上行共享信道(physical uplink shared channel，PUSCH)子载波间隔组合下，每个PRACH信道占用不同的频域带宽。
针对Reduced capability UE，接收频域带宽会受限。对于接收频域带宽受限的Reduced capability UE而言，传统PRACH FDM对应的频域带宽可能会超过受限的最大频域带宽，故传统PRACH FDM配置并不能与Reduced capability UE能力匹配。
本公开实施例提供一种频分复用方法，在该频分复用方法中确定进行频分复用的PRACH(PRACH FDM)的总带宽，使PRACH FDM配置匹配终端能力。
可以理解的是，本公开实施例中“PRACH进行频分复用”和“PRACH FDM”有时会交替使用，但本领域技术人员应理解其含义的一致性。
进一步的，本公开实施例中为描述方便，将用于确定进行频分复用的PRACH的总带宽的参数，称为第一参数。
图2是根据一示例实施例示出的一种频分复用方法的实施流程图。参阅图2所示，频分复用方法包括如下步骤。
在步骤S11中，确定第一参数，第一参数用于确定进行频分复用的PRACH占用的总带宽。
本公开实施例中，进行频分复用的PRACH占用的总带宽可以是小于指定频域带宽的，以实现限制PRACH进行频分复用时占用的带宽小于指定频域带宽。
本公开实施例可以根据终端类型确定进行频分复用的PRACH占用的总带宽。一种实施方式中，针对Reduced capability UE可以将进行频分复用的PRACH占用的总带宽设置为小于Reduced capability UE的最大接收频域带宽。另一种实施方式中，针对普通NR UE进行频分复用的PRACH占用的总带宽可以基于PRACH FDM传统配置中的频域带宽进行设定。
本公开实施例中，为描述方便并区分不同类型终端，以第一类型终端和第二类型终端表示不同的类型终端。其中，第一类型终端和第二类型终端的能力不同，例如第一类型终端的能力低于第二类型终端的能力。
本公开实施例中第一类型终端和第二类型终端可以是具有不同的能力。例如终端的能力可以是以下的一项或多项：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。终端的能力不同可以是收发带宽、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不同。一示例中，第一类型终端可以是Reduced capability UE，第二类型终端可以是NR终端，也称为latency UE。
本公开实施例可以针对第一类型终端和第二类型终端分别配置不同的PRACH FDM配置信息。也可以理解为是，针对第一类型终端和第二类型终端分别配置不同的第一参数，或者也可以理解为是，针对第一类型终端和第二类型终端分别配置不同的进行频分复用的PRACH占用的总带宽。
本公开实施例中，指定频域带宽可以是对其中的一种指定类型终端的最大接收频域带宽。例如，指定频域带宽可以是第一类型终端的最大接收频域带宽。即，进行频分复用的PRACH占用的总带宽小于第一类型终端的最大接收频域带宽。
本公开实施例中可以针对终端能力进行PRACH FDM占用总带宽的确定，使PRACH FDM占用的总带宽小于指定频域带宽。例如，配置针对Reduced capability UE确定适配的PRACH FDM配置，使得PRACH FDM配置能更好与Reduced capability UE用户能力匹配。
本公开实施例以下结合实际应用对上述实施例中涉及的频分复用方法进行说明。
本公开实施例一种实施方式中，对进行频分复用时的PRACH FDM因子进行限制，以限制PRACH进行频分复用时占用的带宽。其中，PRACH FDM因子可以理解为是进行频分复用的PRACH个数。
本公开实施例中，第一参数中可以包括支持进行FDM复用的PRACH个数集合，以下称为第一PRACH个数集合。例如，本公开实施例中第一PRACH个数集合中可以包括 {1，2，4}。或者第一PRACH个数集合中可以包括{1，2}。
本公开实施例中，第一PRACH个数集合中包括的PRACH个数表征进行频分复用的PRACH个数小于指定数值。例如，本公开实施例中第一PRACH个数集合中可以包括{1，2，4}，限制进行频分复用的PRACH个数小于4个。或者第一PRACH个数集合中可以包括{1，2}，限制进行频分复用的PRACH个数小于2个。
本公开实施例中第一PRACH个数集合可以基于传统的PRACH FDM因子表征的PRACH个数集合确定。其中，为方便描述，本公开实施例中将用于确定第一PRACH个数集合的PRACH个数集合称为第二PRACH个数集合。
一种实施方式中，所述第一PRACH个数集合为第二PRACH个数集合的子集。例如，第二PRACH个数集合为{1，2，4，8}，第一PRACH个数集合可以是{1，2，4}，也可以是{1，2}。
本公开实施例中，第一PRACH个数集合和/或第二PRACH个数集合可以基于终端的类型确定。一示例中，本公开实施例中，基于第一类型终端确定第一PRACH个数集合，即第一PRACH个数集合对应第一类型终端。本公开实施例中，也可以基于第二类型终端确定第二PRACH个数集合。其中，第二PRACH个数集合对应第二类型终端。
本公开实施例中，第一类型终端的能力低于第二类型终端的能力。例如，第一类型终端可以是Reduced capability UE，第二类型终端可以是NR终端。
本公开实施例中涉及的频分复用方法，一种实施方式中，可以对某一指定类型终端所有进行频分复用的PRACH的带宽进行限制。一示例中，本公开实施例对第一类型终端所有进行频分复用的PRACH的带宽进行限制。例如，针对Reduced capability UE，在所有进行频分复用的情况下限制PRACH FDM因子。比如限制进行频分复用的PRACH支持FDM因子为{1，2，4}或者支持FDM因子为{1，2}。那么针对传统终端可用的FDM因子集合为{1，2，4，8}，针对Reduced capability UE的FDM因子集合为{1，2，4}。
本公开实施例涉及的频分复用方法，另一种实施方式中，可以针对某一指定类型终端在特定通信条件下进行频分复用的PRACH的带宽进行限制。一示例中，针对第一类型终端指定子载波间隔对应进行频分复用的PRACH的带宽进行限制。例如，针对Reduced capability UE，在部分通信条件下限制PRACH FDM因子，比如当SCS＝30k Hz时，限制FDM的个数。而当SCS＝15kHz时，则不做此限制。
一种实施方式中，第一参数中包括SCS参数，SCS参数用于指示指定SCS。其中，SCS参数所指示的指定SCS，可以理解为是需要进行PRACH FDM因子限制的SCS。或者也可以理解为是，在第一参数中承载并指示的SCS对应的进行频分复用的PRACH占用的总 带宽进行确定。
一种实施方式中，在不同的子载波间隔下所对应的第一随机接入信道个数集合不同。例如一示例中，表2所示的PRACH SCS为1.25，15时，对应第一随机接入信道个数集合{1，2，4，8}，PRACH SCS为5，30，60，120时，对应第一随机接入信道个数集合{1，2，4}。
PRACH SCS 第一随机接入信道个数集合
1.25,15 1,2,4,8
5,30,60,120 1,2,4
本公开实施例另一种实施方式中，对进行频分复用时的每个PRACH FDM所占用的频率资源个数进行限制，例如对物理资源块(Physical Resource Block，PRB)个数进行限制，以限制PRACH进行频分复用时占用的带宽。
本公开实施例一种实施方式中，第一参数包括对应不同子载波间隔下每个PRACH所占用的频率资源个数，以下称为第一频率资源个数。其中，本公开实施例中第一频率资源个数可以理解为是对每个PRACH所占用的频率资源个数进行限制的频率资源个数。
本公开实施例中第一频率资源个数可以基于传统终端(例如NR终端)频率资源个数确定。其中，为方便描述，本公开实施例中将用于确定第一频率资源个数的频率资源个数称为第二频率资源个数。
一种实施方式中，第一频率资源个数小于第二频率资源个数。
本公开实施例中，第一频率资源个数和/或第二频率资源个数可以基于终端的类型确定。一示例中，本公开实施例中，基于第一类型终端确定第一频率资源个数，即第一频率资源个数对应第一类型终端。本公开实施例中，也可以基于第二类型终端确定第二频率资源个数。其中，第二频率资源个数对应第二类型终端。
本公开实施例中，第一类型终端的能力低于第二类型终端的能力。例如，第一类型终端可以是Reduced capability UE，第二类型终端可以是NR终端。
本公开实施例中用于限制PRACH进行频分复用时占用的带宽第一频率资源个数可以直接承载在第一参数中。其中，第一参数可以是预配置消息。例如，本公开实施例中可以在协议中定义不同PRACH SCS和PUSCH SCS下每个PRACH所占用的频率资源个数。 比如针对Reduced capability UE的每个PRACH所占用PRB个数为正常NR终端每个PRACH所占用PRB个数的一半。
本公开实施例中用于限制PRACH进行频分复用时占用的带宽第一频率资源个数可以通过缩放因子表征。一种实施方式中，第一参数中包括缩放因子，缩放因子用于表征所述第一频率资源个数相对所述第二频率资源的比例。其中，本公开实施例中包括缩放因子的第一参数可以承载在广播信令中。一示例中，在广播信令中通知一个缩放因子a，则针对Reduced capability UE，每个PRACH所占用的每一个PRACH资源＝a*正常用户对应的PRACH资源。其中，a可以理解为是小于1并大于0的数值。一示例中，针对Reduced capability UE，每个PRACH所占用PRB个数为：a*NR终端对应的每个PRACH所占用PRB个数。
本公开实施例中针对不同类型终端，配置不同的频分复用方案，可以使频分复用方法匹配终端能力，提高通信性能。
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。
本公开的一些实施例提供了一种频分复用方法，包括：
确定第一类型UE对应的第一随机接入信道个数集合，确定第二类型UE对应的第二随机接入信道个数集合，其中所述第一随机接入信道个数集合中包括的随机接入信道个数，为第二随机接入信道个数集合中包括的随机接入信道个数的真子集；
其中，第一类型UE与第二类型UE不同。
上述实施例中，是针对所有的第一类型UE都确定不同于第二类型UE的第一随机接入信道个数集合。
在一些实施例中，第一类型终端的能力低于第二类型终端的能力。例如，第一类型终端可以是Reduced capability UE，第二类型终端可以是NR终端。
本公开实施例中涉及的频分复用方法，一种实施方式中，可以对某一指定类型终端所有进行频分复用的PRACH的带宽进行限制，以生成第一随机接入信道个数集合。一示例中，本公开实施例对第一类型终端所有进行频分复用的PRACH的带宽进行限制。例如，针对Reduced capability UE，在所有进行频分复用的情况下限制PRACH FDM因子。比如限制进行频分复用的PRACH支持FDM因子为{1，2，4}或者支持FDM因子为{1， 2}。那么针对传统终端可用的FDM因子集合为{1，2，4，8}，针对Reduced capability UE的FDM因子集合为{1，2，4}。
在一些实施例中，第一类型UE对应的第一随机接入信道个数集合，为能力缩减UE(Reduced capability UE，)进行频分复用的PRACH支持FDM因子；例如，可以为{1，2，4}。在一些实施例中，第二类型UE对应的第二随机接入信道个数集合，为NR UE进行频分复用的PRACH支持FDM因子；例如，可以为{1，2，4，8}。
具体的，可以参考前面任一实施例中对于细节的描述，相同的技术内容在此不再赘述。
本公开的一些实施例提供了一种频分复用方法，包括：
确定满足第一条件的第一类型UE对应的第一随机接入信道个数集合，确定第二类型UE对应的第二随机接入信道个数集合，其中所述第一随机接入信道个数集合中包括的随机接入信道个数，为第二随机接入信道个数集合中包括的随机接入信道个数的真子集；
其中，第一类型UE与第二类型UE不同。
上述实施例中，是针对满足第一条件的第一类型UE都确定不同于第二类型UE的第一随机接入信道个数集合。
在一些实施例中，第一类型终端的能力低于第二类型终端的能力。例如，第一类型终端可以是Reduced capability UE，第二类型终端可以是NR终端。
本公开实施例中涉及的频分复用方法的一种实施方式中，可以对第一类型UE中的部分UE进行频分复用的PRACH的带宽进行限制，以生成第一随机接入信道个数集合。例如，该第一条件可以为该第一类型UE的子载波间隔(Subcarrier Spacing，SCS)参数。举例来说，当Reduced capability UE的子载波间隔SCS＝30MHz的时候，对进行频分复用的PRACH的带宽进行限制；而当Reduced capability UE的子载波间隔SCS≠30MHz的时候，该第一类型UE应用于第二类型UE相同的频分复用的PRACH的带宽；即，当SCS≠30MHz的时候，不对频分复用的PRACH的带宽进行限制。
具体的，可以参考前面任一实施例中对于细节的描述，相同的技术内容在此不再赘述。
本公开的一些实施例提供了一种频分复用方法，包括：
确定第一类型UE和/或第二类型UE对应的PRACH FDM所占用的频率资源数量集合；
其中，第一类型UE与第二类型UE不同。
在一些实施例中，第一类型终端的能力低于第二类型终端的能力。例如，第一类型终端可以是Reduced capability UE，第二类型终端可以是NR终端。
本公开实施例中，对于第一类型UE和第二类型UE可以采用相同的PRACH FDM所占用的频率资源个数集合。具体的，该PRACH FDM所占用的频率资源个数集合中，包括 了不同的子载波间隔所对应的频率资源数量，这样可以针对通信协议中已经确定的每一子载波间隔，都确定其所对应的频率资源数量。在本公开的一些实施例中，每一子载波间隔所对应的频率资源的数量不相同。在本公开的一些实施例中，一些不同的子载波间隔，对应相同的频率资源的数量。例如，当SCS＝15MHz，第一类型UE和第二类型UE对应于第一频率资源数量；当SCS＝30MHz，第一类型UE和第二类型UE对应于第二频率资源数量；且第一频率资源数量≠第二频率资源数量。
具体的，可以参考前面任一实施例中对于细节的描述，相同的技术内容在此不再赘述。
本公开的一些实施例提供了一种频分复用方法，包括：
确定第一类型UE和第二类型UE对应的PRACH FDM所占用的频率资源数量集合；其中对于相同的子载波间隔，第一类型UE对应的PRACH FDM所占用的频率资源数量，小于或等于第二类型UE对应的PRACH FDM所占用的频率资源数量；
其中，第一类型UE与第二类型UE不同。
本公开实施例中，对于相同的子载波间隔，第一类型UE和第二类型UE采用不同的PRACH FDM所占用的频率资源个数集合。例如，第一类型UE可以对应缩放参数α；设子载波间隔a时，第一类型UE对应的PRACH FDM所占用的频率资源个数为A1，第二类型UE对应的PRACH FDM所占用的频率资源个数为A2，则A1＝α×A2；其中a≤1。即，相同子载波间隔，第一类型UE对应的频率资源个数，为第二类型UE对应的子载波资源个数的α倍；而对于不同的子载波间隔，可以采用相同的缩放参数α，也可以采用不同的缩放参数α。当然，利用缩放参数α是一种比较简单易行的方式，本公开实施例中也可以为第一类型UE和第二类型UE对应的每一个子载波间隔，都设定频率资源个数；这些频率资源个数可以相同或不同。
具体的，可以参考前面任一实施例中对于细节的描述，相同的技术内容在此不再赘述。
基于相同的构思，本公开实施例还提供一种频分复用装置。
