Description

下行控制信息传输方法及装置 技术领域
本公开涉及通信领域。
背景技术
基于目前的Rel-15版本的窄带物联网(Narrow Band Internet of Things,简称为NB-IoT),机器型通信(Machine-Type Communication,简称为MTC)和第五代移动通信NR(New Radio,新一代无线通信)系统中,其多进程机制有效的提升了数据传输效率。对于单个接入的用户而言,为提高系统吞吐量,具有周期性的业务如数据域的网络电话(Voice over Internet Protocol,简称为VoIP)业务,采用半静态的调度方式,具有一次授权,周期使用的特点,大大降低了控制信令的开销。但对于非周期性业务,此种方式已不太适合,在Rel-16的立项中,明确提出了需要利用一个下行物理控制信道(Physical Downlink Control Channel,简称为PDCCH)来调度多个传输块(Transport Blocks,简称为TB)的调度增强方向。

具体实施方式
下文中将参考附图并结合实施例来详细说明本公开。需要说明的是,在不冲突的情况下,本公开中的实施例及实施例中的特征可以相互组合。
需要说明的是,本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。
基于单TB调度时,一个TB的调度需要一个PDCCH进行指示。在利用一个PDCCH对多个TB进行调度时,需要指示每个TB的配置信息。当系统支持的最大混合自动重传请求(HybridAutomatic Repeat Request,简称为HARQ)进程数量越多,其一调多的能力越强,即一个PDCCH可调用越多的TB数量。而在目前版本中,每个TB均需要一个PDCCH的下行控制信息(Downlink Control Information,简称为DCI)来指示,DCI内包含诸多关于资源调度,调制编码,进程等不同域的信息。如何将多个TB的控制信息在一个PDCCH中进行指示,并使得开销较小是调度增强面临的主要问题。而相关技术针对如何将多个TB的控制信息在一个PDCCH中进行指示的问题,尚未提出解决方案。
本公开实施例提供一种下行控制信息传输方法,该方法可以在移动终端、计算机终端或者类似的运算装置中执行。以运行在移动终端上为例,图1是本公开实施例提供的执行下行控制信息传输方法的移动终端的一种硬件结构框图。如图1所示,移动终端可以包括一个或多个(图1中仅示出一个)处理器102(处理器102可以包括但不限于微处理器(Microcontroller Unit,MCU)或可编程逻辑器件(Field Programmable Gate Array,FPGA)等处理装置)和用于存储数据的存储器104。根据本公开提供的实施例,上述移动终端还可以包括用于通信功能的传输设备106以及输入输出设备108。本领域普通技术人员可以理解,图1所示的结构仅为示意,其并不对上述移动终端的结构造成限定。例如,移动终端还可包括比图1中所示更多或者更少的组件,或者具有与图1所示不同的配置。
存储器104可用于存储计算机程序,例如,应用软件的软件程序以及模块,如本公开实施例提供的下行控制信息传输方法对应的计算机程序,处理器102通过运行存储在存储器104内的计算机程序,从而执行各种功能应用以及数据处理,即实现上述的方法。存储器104可包括高速随机存储器,还可包括非易失性存储器,如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一示例性实施例中,存储器104可进一步包括相对于处理器102远程设置的存储器,这些远程存储器可以通过网络连接至移动终端10。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输设备106用于经由一个网络接收或者发送数据。上述的网络具体实例可包括移动终端10的通信供应商提供的无线网络。在一示例性实施例中,传输设备106包括一个网络适配器(Network Interface Controller,简称为NIC),其可通过基站与其他网络设 备相连从而可与互联网进行通讯。在一示例性实施例中,传输设备106可以为射频(Radio Frequency,简称为RF)模块,其用于通过无线方式与互联网进行通讯。

下面通过具体示例对本公开实施例进行详细描述。
示例1
本实施例主要用于多TB调度增强时4TB调度场景,目的是减少信令开销,实现多TB调度,提高传输效率,降低开销。特点是在多TB调度时,新传TB和重传TB不可混传,最大TB数量等于进程数量。且其反馈为多比特反馈,即4TB调度,则进行4比特的反馈。
根据其特点,4TB传输时,其反馈方式不论是采用多少个上行资源对4个TB进行反馈,其反馈信息为4比特。进一步地,各个TB不可混传,则NDI域可统一指示所有进程的调度。则进程的调度至少包含下述状态之一。
Table 1-1:4进程非混传状态调度
Figure PCTCN2019114249-appb-000001
Figure PCTCN2019114249-appb-000002
其中,在2TB和3TB调度时,进程可以随意组合。

Figure PCTCN2019114249-appb-000006
从总的原则上来说,保证进程0,1,2,3被调度,以及有一个单进程的状态被调度,其他都可以从剩下的3个单进程状态,6个2进程状态,4个3进程状态中任意选择6个。其次在一次调度多个进程时,多个进程编号尽量连续,且每次调度的进程互不重叠。
此时,进程域使用3比特可实现对4个进程下多个TB的调度。其NDI域1比特对所有进程进行新传与重传的指示。其通过3比特的进程域指示方式,能实现连续TB数量的调度,且不论何种重传状态,最多使用两个PDCCH即可实现调度。举例说明如下:以表1-1为例,当多比特反馈机制表明新传的4个TB有3个需要重传,即进程0,1,3对应的TB需要重传,则此时可以通过先调度进程0和1的TB,在调度进程3对应的TB,通过两次调度实现。
本实施例通过3比特调度4进程的方式,实现一个PDCCH调度4个TB的进程调度指示。
示例2
本实施例主要用于多TB调度增强时4TB调度场景,目的是 减少信令开销,实现多TB调度,提高传输效率,降低开销。特点是在多TB调度时,新传TB和重传TB可以混传,NDI域与HARQ进程域对4TB调度进行指示,其反馈方式为多比特反馈。
根据其特点,4TB传输时,其反馈比特有4比特,能反馈所有进程的传输情况。进一步的,由于新传TB与重传TB可以混合传输,每个TB的新传或重传状态都需要指示给UE。当NDI域与进程域分开指示,如进程域调度4进程或者直接指示调度的进程数量,或者调度的TB数量,而NDI域则指示4个进程;则进程域需要2到4比特,NDI域需要4比特,共需要6到8比特,其DCI开销较大,对于MTC或NB-IoT系统都难以接受,所以我们考虑将进程域与NDI域进行联合指示,减少DCI开销。
TB数量满足2分规则,最简单的一种如表Table 2-1所示。
Table 2-1:二分规则约束下4进程混传状态调度
Figure PCTCN2019114249-appb-000007
最多两次调度可用实现任意TB,任意进程的调度。上表共有24个状态,5比特即可实现指示。同时注意到,其没有支持3进 程的一次调度。
支持连续数量的TB调度,其中一种方式如表Table 2-2所示。
Table 2-2:连续TB数量约束下4进程混传状态调度
Figure PCTCN2019114249-appb-000008
此时共有31个状态,采用5比特可实现指示,当加入更多的混传或新传状态都会导致其开销增加到6比特以上。若采用5比特则依然还可加入一个混传状态。
在最大支持10进程,且支持一个PDCCH调度最大TB数目为4的混传时,可以将10进程分为4+4+2三组,即一组有4进程,另一组有4进程,第三组为剩下的2进程。4进程的混传采用上述方式,2进程混传采用2比特指示。或者采用4进程+偏移量的形 式,偏移量需要3比特指示,根据不同的偏移量取值调度的进程为进程0,1,2,3;进程1,2,3,4;进程2,3,4,5;进程3,4,5,6;进程4,5,6,7;进程5,6,7,8;进程6,7,8,9。而4进程的混传可采用上述方式。其偏移量在本质上是一种进程可重叠的分组,偏移量的指示域相当于组号域。
在最大支持16进程时,且支持一个PDCCH调度最大TB数目为4时,将16进程分为4+4+4+4两组,每组4个进程。4TB的混传采用上述方式。
示例3
本实施例主要用于多TB调度增强时8TB调度非混传场景,目的是减少信令开销,实现多TB调度,提高传输效率,降低开销。特点是在多TB调度时,新传TB和重传TB不可混传,8个TB需要8个进程相对应,且反馈方式为多比特反馈。
根据上述特点,多比特反馈为可以为8比特反馈信息,表明8个进程所对应的8个TB的传输情况。由于新传信息与重传信息分开,则NDI信息可与进程域指示分别指示,如1比特NDI指示所有进程的传输情况,或者多个比特指示。
对于8进程的8TB调度传输情形,给出一种具体的进程调度方法。除了单进程调度的是单个TB外,其他的进程数量均为偶数。说明如下。
Table 3-1:特定数量约束下的8进程调度
Figure PCTCN2019114249-appb-000009
Figure PCTCN2019114249-appb-000010
即TB数量为集合{1,2,4,6,8}中的元素。对于单个进程的传输,则一次调度就可实现;对于2进程传输,最多需要两次调度;对于3进程的传输,最多需要3次调度,最少2次;对于4进程,5进程,6进程和7进程,最多4次调度。最少分别为1次,2次,1次,2次。以上表中共16个状态,需要4比特进程域进行指示。显然6TB的调度可以为任意6个进程。4个TB,2个TB也可以是任意互不重叠的组合,如4TB的进程可以是进程0,1,3,4和进程2,5,6,7。
本公开实施例还提供另外一种约束方法,其调度的TB数列满足斐波那契数列(Fibonacci Sequence)变化规律,即TB数量是集合{1,2,3,5,8}中的元素,其中一种进程状态分配方案如表Table 3-2所示。
Table 3-2:斐波那契数列约束下的8进程调度
Figure PCTCN2019114249-appb-000011
Figure PCTCN2019114249-appb-000012
以上共有状态26个,利用5比特即可实现指示。采用上述方 案的好处在于任何一个进程数量的调度最少都可能只需要2次调度实现。此时采用5比特还可以加入6个状态,选择任意的状态加入即可。
在最大支持10进程,且支持一个PDCCH调度最大TB数目为8时,可以将10进程分为8+2两组,即一组有8进程,另一组有剩余两进程。或者采用8进程+偏移量的形式,偏移量需要1~2比特指示,根据不同的偏移量取值调度的进程为进程0,1,2,3,4,5,6,7;进程1,2,3,4,5,6,7,8;进程2,3,4,5,6,7,8,9。
在最大支持16进程时,且支持一个PDCCH调度最大TB数目为8时,将16进程分为8+8两组,每组8个进程。或者采用8进程加偏移量的形式,偏移量需要3~4比特。其偏移量在本质上是一种进程可重叠的分组,偏移量的指示域相当于组号域。
在本示例中基于多比特反馈的方式,通过采用4比特或者5比特的方式为8进程调度提供了非混传的指示方法。
示例4
本实施例主要用于多TB调度增强时8TB调度的混传场景,目的是减少信令开销,实现多TB调度,提高传输效率,降低开销。特点是在多TB调度时,新传TB和重传TB可混传,且基于多比特反馈机制。
由于8比特的混传状态多达3 8-1=6560种,最多可用10比特指示,其开销未免过大。基于8个TB调度的混传可以基于非混传方案进行进一步地设计,加入所需的特定混传状态,在满足基本需求的条件下降低DCI开销。
Table 4-1:8进程混传调度
Figure PCTCN2019114249-appb-000013
Figure PCTCN2019114249-appb-000014
Figure PCTCN2019114249-appb-000015
此时不包括6TB调度,上述一共有状态30+22=42个,需要6比特指示。显然6比特指示会有22个状态剩余,可以加入更多的状态以增加其灵活性。例如参考表Table3-1中的状态,引入6个TB的调度,此时新传与重传状态各一个,混传状态加入12个,则总共有了58个,则还有6个状态可以使用。
基于table 3-2,可以给出另一种混传方案,如表Table 4-2所示。
Table 4-2:斐波那契数列约束下的8进程混传调度
Figure PCTCN2019114249-appb-000016
Figure PCTCN2019114249-appb-000017
Figure PCTCN2019114249-appb-000018
表Table 4-2中,所有状态有26+52+35+18+4=135个。去掉7个状态便只需7比特便可进行表示,否则需要8比特进行表示。
在最大支持10进程,且支持一个PDCCH调度最大TB数目为8的混传时,可以将10进程分为8+2两组,即一组有8进程,另一组有剩余两进程。8进程的混传采用上述方式,2进程混传采用2比特指示。或者采用8进程+偏移量的形式,偏移量需要1~2比特指示,根据不同的偏移量取值调度的进程为进程0,1,2,3,4,5,6,7;或者,进程1,2,3,4,5,6,7,8;或者,进程2,3,4,5,6,7,8,9。而8进程的混传可采用上述方式。
在最大支持16进程时,且支持一个PDCCH调度最大TB数目为8时,将16进程分为8+8两组,每组8个进程。或者采用8进程加偏移量的形式,偏移量需要3~4比特。8进程的混传调度方式可采用上述。其偏移量在本质上是一种进程可重叠的分组,偏移量的指示域相当于组号域。
示例5
本示例主要用于多TB调度增强时对混传和非混传场景下DCI中RV版本和TPC信令的指示。
根据上述特点,在非混传时RV版本与混传时RV版本有所区别。在非混传时,所有TB的传输次数都是一样的,所以可以共用RV版本。但对于混传时,多个TB的传输情况不一样时,其RV版本对应应该不同。所以当非混传时,所指示的多个传输块的RV相同,根据DCI中RV指示信令确定;当混传时,首传传输块的RV固定为0,重传传输块RV根据DCI中RV指示信令确定。
对于NB-IoT而言,用于上行传输的DCI format N0有1比特冗余版本指示的信令域。对于非混传时,多TB调度可共用1比特RV冗余版本信令域。对于混传时,由于2个进程的TB可能处于一个新传一个重传的状态,所以固定新传使用RV的版本0,即RV0版本;而重传的RV版本依旧由该信令域指示。
对于MTC CE mode B,并无冗余版本指示,新传与重传都采用同一个冗余版本。对于MTC CE Mode A,冗余版本信令域大小为2比特,共有4个冗余版本,即,RV0、RV1、RV2和RV3,需要指示。对于非混传情形,所有TB的传输可共用冗余版本指示;对于混传情形,所有的TB可能有的新传有的重传,则新传冗余版本默认为RV0,重传冗余版本由2比特指示即可。
而对于TPC信令,沿用原来的指示方式即可,即无论是基于累积值功控还是绝对值功控方法,TPC信令是对所有调度的TB进行功控指示。而原来的方式是对单个TB进行功控指示。
在本示例中,主要给出了在多TB调度时,对于非混传和混传两种场景下的冗余版本指示方法。
示例6
本实施例主要用于多TB调度增强时,上行反馈资源的确定。
当TB specific反馈时,传输DCI调度的多个TB对应ACK/NACK的上行资源的频域位置相同;其中,TB specific反馈是指每个TB都有单独的1比特反馈信息。
当TB specific反馈且终端为半双工终端时,传输DCI调度的多个TB对应ACK/NACK的上行资源的时域位置在连续有效上行子帧上。
图4是根据本公开实施例的不同的反馈场景的示意图。如图4所示,当multiplexing反馈时,在MTC场景下,传输DCI调度 的多个TB对应ACK/NACK的上行资源的频域位置根据高层配置信令和ARO确定;其中multiplexing反馈是指每个TB有1比特反馈信息,将多个TB的反馈信息放在一个上行PUCCH资源中进行发送。ARO由HARQ-ACK resource offset得到,HARQ-ACK resource offset是DCI的一个信令域。在NB-IoT场景下,multiplexing反馈资源的时域位置主要由DCI指示和多TB调度时的结束TB位置决定。
在本示例中,主要给出了在多TB调度时,其反馈信息的上行资源确定。
示例7
本示例主要用于多TB调度增强时,若需要DCI触发的非周期性CSI上报,非周期CSI上报的子帧位置需要确定。
非周期性CSI,按照原来的方式在PUSCH信道上报,CSI资源会占用TB资源,使得实际传输TB的资源减少,在多TB调度时,确定非周期CSI资源位置,大小和一起传输的TB大小有以下1)~4)四种方式。
1)将非周期CSI资源在第一个新传或重传TB上进行传输。对于非混传情形,CSI资源可在第一个新传TB上传输;或,对于混传情形,CSI资源可在第一个重传TB上传输。
2)与非周期CSI资源一起传输的TB比多TB调度时的其他TB要小。
DCI指示的是其他TB的TBS,而包含CSI资源的TBS根据DCI指示的TBS和偏移量确定,所述偏移量为预定义值或信令指示或根据资源大小确定或根据传输TB码率确定或根据DCI指示的MCS确定。
3)采用单独资源对CSI资源进行传输。
例如在进程多TB调度时,需要传输CSI资源,则为CSI分配相应资源,放在第一个传输资源位置。DCI指示多TB调度相关信息。而CSI的资源大小和位置可用通过默认方式确定或根据DCI指示的资源位置和偏移量确定,所述偏移量为预定义值或信令指示或根据资源大小确定或根据传输TB码率确定或根据DCI指示的MCS确定。
4)与非周期CSI资源一起传输的TB对应的资源比多TB调度时的其他TB对应的资源大。
DCI指示的是其他TB的资源位置,而包含CSI资源的TBS根据DCI指示的资源位置和偏移量确定,所述偏移量为预定义值或信令指示或根据TB大小确定或根据传输TB码率确定或根据DCI指示的MCS确定。
