Abstract
一种传输块大小配置方法、装置及存储介质。传输块大小配置方法包括:配置第一传输块大小使用信息和第二传输块大小使用信息;其中,所述第一传输块大小使用信息对应第一类型终端,所述第二传输块大小使用信息对应第二类型终端。实施例中配置第一类型终端对应的第一TBS使用信息,第二类型终端对应的第二TBS使用信息,实现针对不同类型终端TBS使用信息的限制。
Description
本公开涉及通信技术领域,尤其涉及传输块大小(英文全称:Transport block size,英文简称:TBS)配置方法、装置及存储介质。
近年来,物联网蓬勃发展,为人类的生活和工作带来了诸多便利。其中,机器类通信技术(英文全称:Machine Type Communication,英文简称:MTC),窄带物联网技术(英文全称:Narrow band Internet of thing,英文简称:NB-IoT)是蜂窝物联网技术的典型代表。目前这些技术已经广泛用于智慧城市(例如抄表)、智慧农业(例如温度湿度等信息的采集)以及智慧交通(例如共享单车)等诸多领域。
NB-IoT进行通信传输时,基于TBS表格中的TBS索引(I_
TBS)以及为TBS分配的资源分配量(I_
SF)确定TBS值。比如当I_
TBS为10,I_
SF为2时,所对应的TBS值为504。对于NB-IoT的下行,在Release 16阶段,支持QPSK调制方式。NB-IoT支持同频段(Inband)工作模式在Inband工作模式下,会限制0≤I
TBS≤10。
为了进一步提高NB-IoT的传输速率,在Release 17阶段进一步引入16QAM等高阶调制方式。对于下行所支持的TBS,允许扩大所支持的最大TBS数。对于上行传输,要求不能增加TBS的数。由于引入了高阶的调制方式,TBS表格也会随之扩展。然而,针对高阶调制模式在Inband工作模式下,并未进行TBS使用信息的限制。

应当理解的是,以上的一般描述和后文的细节描述仅是示例性和解释性的,并不能限制本公开。

图6是根据一示例性实施例示出的一种确定TBS配置的装置的框图。
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TBS配置方法可应用于图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支持MTC和NB-IoT的设备。由于支持MTC和NB-IoT的设备大多数部署在地下室,并且由于设备的硬件限制,导致其覆盖能力不如传统的长期演进(Long Term Evolution,LTE)终端。因此,在MTC和NB-IoT中采用了重复传输以累积功率,进而达到覆盖增强的效果。简单来说,重复传输即在多个时间单位内传输相同的传输内容。这个时间单位可以是一个子帧,也可以是多个子帧。
另外,由于支持MTC和NB-IoT的设备大多部署在不容易充电或者更换电池的场景,比如野外,或者地下室中,因此对支持MTC和NB-IoT的设备的功率节省是支持MTC和NB-IoT的设备的一大特性。
相关技术中,支持MTC和NB-IoT的设备进行通信传输时,基于TBS表格中的(I_TBS)以及为TBS分配的I_SF确定TBS值。NB-IoT的下行TBS表格如下表1所示。
表1
其中,表1中I_TBS为TBS索引,I_SF为TBS分配的资源分配量。表1中的数字为根据TBS索引与为TBS分配的资源分配量确定的TBS值。比如当I_TBS为10,I_SF为2时,所对应的TBS值为504。对于NB-IoT的下行,在Release 16阶段,支持QPSK调制方式。
支持NB-IoT的设备,支持如下四种工作模式:standalone工作模式,即NB-IoT的系统工作在独立部署。guard band工作模式,即NB-IoT系统工作在其他系统的保护频带。同频带相同物理小区标识(英文全称:Inbandsame Physical Cell Identifier,英文简称:Inbandsame PCI)工作模式,即与LTE系统共存,并且与LTE共用与PCI相关的参数。同频带不同物理小区标识(英文全称:Inband different Physical Cell Identifier,英文简称:Inband different PCI)工作模式,即与LTE系统共存,但是与LTE使用不同的PCI相关参数。
支持NB-IoT的设备对于支持的四种工作模式选择,通过在NB-IoT的高层信令中的operationModeInfo参数进行指示。当operationModeInfo分别设置为00或01时,分别表示当前使用的是inband samePCI或inband differentPCI。当上述operation Mode Info指示00或01时,则0≤I
TBS≤10,而对于其他工作模式则没有此限制。
对于引入16QAM等高阶调制方式并支持NB-IoT的设备,在operation Mode Info指示00或01时,并没有对TBS使用信息的限制。
有鉴于此,本公开实施例提供一种TBS配置方法,针对不同类型终端分别配置TBS使用信息,实现针对不同类型终端TBS使用信息的限制。
本公开实施例中将不同类型终端中任意两种不同类型的终端称为第一类型终端和第二类型终端。将对应第一类型终端配置的TBS使用信息称为第一TBS使用信息,将对应第二类型终端配置的TBS使用信息称为第二TBS使用信息。
可以理解的是,本公开实施例中配置TBS使用信息对应的终端类型的数量不进行限定。例如,一示例中针对至少两种类型终端配置TBS使用信息。当然,本公开实施例中涉及的终端类型不限定两种类型。进一步的,本公开实施例中针对第一类型终端和/或第二类型终端中每种类型不限于一个,也可以是多个。
图2是根据一示例性实施例示出的一种TBS配置方法的流程图,如图2所示,TBS配置方法用于网络设备中,包括以下步骤。
在步骤S11中,配置第一TBS使用信息和第二TBS使用信息。
其中,第一TBS使用信息对应第一类型终端,第二TBS使用信息对应第二类型终端。
本公开实施例中为第一类型终端配置第一TBS使用信息,为第二类型终端配置第二TBS使用信息,以满足不同类型终端对TBS使用信息限制的差异化需求,实现针对不同类型终端TBS使用信息的限制。
可以理解的是,本公开实施例中第一类型终端和第二类型终端可以是支持不同调制阶数进行调制的终端。
一示例中,第一类型终端可以是支持低阶调制的终端。一种实施方式中,第一类型终端支持的调制阶数低于第一调制阶数阈值。其中,第一调制阶数阈值可以根据实际需求进行设定。例如,本公开实施例中第一调制阶数阈值可以设置为16。在一种实施例中,如,第一类型终端只支持QPSK调制方式,其调制阶数为4,小于16。
另一示例中,第二类型终端可以是支持高阶调制的终端。一种实施方式中,第二类型终端支持的最大调制阶数高于或等于第一调制阶数阈值。其中,第一调制阶数阈值可以根据实际需求进行设定。例如,本公开实施例中第一调制阶数阈值可以设置为16。
本公开实施例中,第一类型终端为不支持16QAM高阶调制的终端,第二类型终端为支持16QAM高阶调制的终端。
其中,配置第一类型终端的第一TBS使用信息时,可以配置第一类型终端对应的TBS索引使用范围。比如,第一类终端为不支持16QAM的终端,第一类终端的TBS索引使用范围为0到10,即0≤I
TBS≤10。
本公开实施例中第二类型终端支持的调制阶数高于或等于第一调制阶数阈值的情况,可以配置第二类型终端的第二TBS使用信息不同于第一类型终端的第一TBS使用信息,即第一TBS使用信息与第二TBS使用信息不同。
一种实施方式中,第一TBS使用信息和第二TBS使用信息不同可以是第一类型终端支持的TBS索引使用范围与第二类型终端支持的TBS索引使用范围不同。
一示例中,第一类型终端支持的TBS索引使用范围与第二类型终端支持的TBS索引使用范围不同,可以是第一类型终端支持的TBS使用的最大索引与第二类型终端支持的TBS使用的最大索引不同。比如,第一类型终端支持的TBS使用的最大索引小于第二类型终端支持的TBS使用的最大索引(第二类型终端支持的TBS使用的最大索引大于第一类型终端支持的TBS使用的最大索引)。比如,第一类终端的TBS索引使用范围为0到10,第二类型终端的TBS索引使用范围为0到13。
一种实施方式中,第一TBS使用信息和第二TBS使用信息不同可以是TBS索引与TBS值之间的映射关系(TBS表格)不同。本公开实施例中为描述方便表征TBS索引与TBS值之间映射关系的TBS表格称为第一TBS表格。即,本公开实施例中第一类型终端使用的第一TBS表格和第二类型终端使用的第二TBS表格不同。
一种实施方式中,第一类型终端使用的第一TBS表格和第二类型终端使用的TBS表格不同,可以是第一类型终端支持的TBS值与第二类型终端支持的最大TBS值不同。比如,第一类型终端支持的最大TBS值小于第二类型终端支持的最大TBS值(第二类型终端支持的最大TBS值大于第一类型终端支持的最大TBS值)。例如第一类型终端使用的最大TBS是680比特,第二类型终端支持的是1352比特。
一种实施方式中,第一TBS使用信息和第二TBS使用信息不同可以是TBS索引与调制编码方案(英文全称:Modulation and Coding Scheme,英文简称:MCS)索引之间的对应关系不同。其中,本公开实施例为描述方便将第一类型终端使用的TBS索引与MCS索引之间的对应关系称为第一映射关系,将第二类型终端使用的TBS索引与MCS索引之间的对应关系称为第二映射关系。其中,第一类型终端使用的第一映射关系和第二类型终端使用的第二映射关系不同。
一种实施方式中,第一类型终端使用的第一映射关系和第二类型终端使用的第二映射关系不同可以是第一类型终端使用的TBS索引与MCS索引相同,第二类型终端使用的TBS索引与MCS索引不同。
其中,TBS索引与MCS索引不同,可以采用诸如表2所示的TBS索引与MCS索引映射方式。
表2
表2中,I
MCS表示MCS索引,Q
m表示调制阶数,I
TBS表示TBS索引。参阅表2所示,I
MCS与I
TBS不同。可以理解的是,本公开实施例表2中I
MCS与I
TBS之间映射的索引值是随机进行分配的,具体索引值本公开实施例不做限定。
进一步的,本公开实施例中提供的TBS配置方法可以是应用于支持NB-IoT的终端的TBS信息配置场景中。其中,支持NB-IoT的终端工作模式为Inband场景时,可用的传输资源相对比较少,故需要减少资源块(英文全称:Resource Block,英文简称:RB)的使用。因此,针对终端工作模式为Inband场景更适用于对TBS使用信息的限制。
一种实施方式中,本公开实施例中针对Inband场景,实施上述涉及的TBS配置方式。即,本公开实施例涉及的TBS配置方法还包括:确定工作模式指示信息指示的工作模式为Inband工作模式。
图3是根据一示例性实施例示出的一种TBS配置方法的流程图,如图2所示,TBS配置方法用于网络设备中,包括以下步骤。
在步骤S21中,确定工作模式指示信息指示的工作模式为Inband工作模式。
在步骤S22中,配置第一TBS使用信息和第二TBS使用信息。其中,第一TBS使用信息对应第一类型终端,第二TBS使用信息对应第二类型终端。
本公开实施例中,Inband工作模式可以是由NB-IoT系统中的工作模式指示信息(operation Mode Info)指示,当operation Mode Info指示为“00”和“01”时,对应的是Inband部署场景,即Inband工作模式。
本公开实施例中,在Inband部署场景下,配置第一TBS使用信息和第二TBS使用信息。其中,第一类型终端使用第一TBS使用信息。第二类型终端使用第二TBS使用信息。
本公开上述实施例中涉及的TBS使用信息有时也可以称为是TBS的使用规则。即,针对Inband的部署场景,配置两套TBS的使用规则(第一TBS使用规则和第二TBS使用规则)。其中,第一类型终端使用第一TBS使用规则。第二类型终端使用第二TBS使用规则。
本公开实施例中,上述实施例涉及的TBS配置方法可以应用于网络设备和终端交互通信的场景中。
其中,网络设备和终端进行交互通信时,网络设备向终端发送TBS指示信息,该TBS指示信息用于指示第一TBS使用信息或第二TBS使用信息。其中,针对第一类型终端,网络设备发送用于指示第一TBS使用信息的TBS指示信息。针对第二类型终端发送用于指示第二TBS使用信息的TBS指示信息。
其中,第一类型终端接收到用于指示第一TBS使用信息的TBS指示信息后,确定TBS使用信息为第一TBS使用信息,按照第一TBS使用信息进行通信。
其中,第二类型终端接收到用于指示第二TBS使用信息的TBS指示信息后,确定TBS使用信息为第二TBS使用信息,按照第二TBS使用信息进行通信。
本公开实施例中第一类型终端使用第一TBS使用信息进行通信,第二类型终端使用第二TBS使用信息进行通信,实现针对不同类型终端使用不同的TBS使用信息,满足不同类型终端对TBS使用信息限制的差异化需求。
基于相同的构思,本公开实施例还提供一种TBS配置装置。
可以理解的是,本公开实施例提供的TBS配置装置为了实现上述功能,其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤,本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行,取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能,但是这种实现不应认为超出本公开实施例的技术方案的范围。

一种实施方式中,第二类型终端支持的调制阶数高于或等于第一调制阶数阈值。
一种实施方式中,处理单元101配置第一类型终端支持的TBS索引使用范围与第二类型终端支持的TBS索引使用范围不同。
一种实施方式中,处理单元101配置第一类型终端支持的TBS使用的最大索引小于第二类型终端支持的TBS使用的最大索引。
一种实施方式中,处理单元101配置第一类型终端使用的TBS表格和第二类型终端使用的TBS表格不同,其中,TBS表格中包括TBS索引和TBS值。
一种实施方式中,处理单元101配置第一类型终端支持的最大TBS值小于第二类型终端支持的最大TBS值。
一种实施方式中,处理单元101配置第一类型终端使用的第二映射关系和第二类型终端使用的第二映射关系不同,其中,第二映射关系表征TBS索引与MCS索引之间的对应关系。
一种实施方式中,处理单元101配置第一类型终端使用的TBS索引与MCS索引相同,第二类型终端使用的TBS索引与MCS索引不同。
一种实施方式中,处理单元101还用于:确定工作模式指示信息指示的工作模式为同频段工作模式。
进一步的,TBS配置装置100包括发送单元,该发送单元用于发送TBS配置指示信息,TBS配置指示信息用于指示第一TBS使用信息或第二TBS使用信息。
本公开实施例还提供一种TBS配置装置,该TBS配置装置可包括接收单元。TBS装置应用于第一类型终端时,接收用于指示第一TBS使用信息的TBS配置指示信息。TBS装置应用于第二类型终端时,接收用于指示第二TBS使用信息的TBS配置指示信息。
