Description

多用户上行数据聚合传输的方法和装置 技术领域
本申请实施例涉及无线通信领域,尤其涉及多用户上行数据聚合传输的方法和装置。
背景技术
第五代(5 th generation,5G)移动通信系统与第四代(4 th generation,4G)移动通信系统相比的一大显著特征就是增加了对超可靠低时延通信(ultra-reliable and low-latency communications,URLLC)业务的支持。URLLC的业务种类包括很多种,典型的用例包括工业控制、无人驾驶、远程手术和智能电网等。对于URLLC业务,一个典型需求是在1毫秒(millisecond,ms)内发送32字节的数据的可靠性要达到99.999%。需要指出的是,上述性能指标仅是个示例,不同的URLLC业务可能对可靠性有不同的需求,比如在某些极端苛刻的工业控制应用场景中,URLLC业务数据的传输成功概率需要在0.25ms内达到99.9999999%。
在很多URLLC应用场景中,数据包往往较小。例如,对于智能工厂中很多典型应用,下行数据包大多是控制命令或管理信令,上行传输是一些动作执行后的反馈信息或者简单的位置更新或外部收集的信息,只有几字节到几十字节。由于URLLC业务数据的传输要求满足非常高的可靠性,这些数据包往往需要使用更多的资源来传输数据,从而保证数据包传输的可靠性。在大连接、小数据包传输的URLLC应用场景下,现有的传输方式对频谱资源造成极大消耗,需要很大的带宽才能保证正常的数据传输。

具体实施方式
图1是本申请的实施例应用的移动通信系统的架构示意图。如图1所示,该移动通信系统包括核心网设备110、无线接入网设备120和至少一个终端设备(如图1中的终端设备130和终端设备140)。无线接入网设备120包括射频单元和基带单元,对于上行数据传输,基带单元可以包括解调模块、解速率匹配模块和信道译码模块。终端设备(如图1中的终端设备130和终端设备140)包括基带单元和射频单元,对于上行数据传输,基带单元可以包括信道编码模块、速率匹配模块和调制模块。终端设备通过无线的方式与无线接入网设备相连,无线接入网设备通过无线或有线方式与核心网设备连接。核心网设备与无线接入网设备可以是独立的不同的物理设备,也可以是将核心网设备的功能与无线接入网设备的逻辑功能集成在同一个物理设备上,还可以是一个物理设备上集成了部分核心网设备的功能和部分的无线接入网设备的功能。终端设备可以是固定位置的,也可以是可移动的。图1只是示意图,该通信系统中还可以包括其它网络设备,如还可以包括无线中继设备和无线回传设备,在图1中未画出。本申请的实施例对该移动通信系统中包括的核心网设备、无线接入网设备和终端设 备的数量不做限定。
无线接入网设备是终端设备通过无线方式接入到该移动通信系统中的接入设备,可以是基站(base station)、演进型基站(evolved NodeB,eNodeB)、发送接收点(transmission reception point,TRP)、5G移动通信系统中的下一代基站(next generation NodeB,gNB)、未来移动通信系统中的基站或WiFi系统中的接入节点等;也可以是完成基站部分功能的模块或单元,例如,可以是集中式单元(central unit,CU),也可以是分布式单元(distributed unit,DU)。本申请的实施例对无线接入网设备所采用的具体技术和具体设备形态不做限定。在本申请中,无线接入网设备简称网络设备,如果无特殊说明,网络设备均指无线接入网设备。
终端设备也可以称为终端、用户设备(user equipment,UE)、移动台、移动终端等。终端设备可以是手机、平板电脑、带无线收发功能的电脑、虚拟现实终端设备、增强现实终端设备、工业控制中的无线终端、无人驾驶中的无线终端、远程手术中的无线终端、智能电网中的无线终端、运输安全中的无线终端、智慧城市中的无线终端、智慧家庭中的无线终端等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。

本申请实施例提供了一种多用户上行数据聚合传输的方法,多个邻近的终端设备交互原始比特信息,终端设备对交互的原始比特信息进行比特聚合和信道编码,从而提高编码增益,提升空口传输效率。
下面通过一些实施例对本申请的技术方案进行详细说明。
图2为本申请实施例提供的一种多用户上行数据聚合传输方法的流程示意图,本实施例涉及的是终端设备向网络设备发送上行数据的具体过程。本实施例的核心思想是,一个终端设备组内的多个终端设备通过交互上行数据获得组内所有终端设备的上行数据。每个终端设备按照一定的规则对该上行数据进行比特聚合,然后各自发送给网络设备。下面以网络设备和第一终端设备执行该方法为例进行描述,该第一终端设备为该终端设备组中的一个终端设备。可以理解的是,该方法的执行主体还可以是网络设备中的一个模块和第一终端设备中的一个模块,例如,芯片。如图2所示,该方法可以包括:
S101、第一终端设备获取第一指示信息。
其中,第一指示信息为N个终端设备中的每一个终端设备的上行数据在第一上行比特序列中的位置信息。这里的第一上行比特序列包括上述N个终端设备中的每一个终端设备的上 行数据。N为大于1的整数,该第一终端设备为上述N个终端设备中的一个。该N个终端设备为上述终端设备组中的N个终端设备。具体的,该N个终端设备可以为上述终端设备组中有数据待传输的N个终端设备。可选的,上述N个终端设备中的每一个终端设备的上行数据是信道编码前的数据。
这里的位置信息可以有不同的实现方式,例如,可以包括N个终端设备中的每一个终端设备的上行数据在第一上行比特序列中的起始位置或结束位置;或者,该位置信息可以包括N个终端设备中的每一个终端设备的上行数据在第一上行比特序列中的序号和第一上行比特序列中的每一个终端设备的上行数据的比特长度。这里的序号可以用来表示N个终端设备中的每一个终端设备的上行数据在第一上行比特序列中的聚合顺序,因此也可以称为聚合序号。以N等于4为例,4个终端设备的聚合序号可以分别是0,1,2,3,也可以分别是1,2,3,4。
具体的,第一终端设备可以通过不同的实现方式获取第一指示信息。例如,第一终端设备可以接收来自网络设备的第一指示信息。对应的,网络设备向第一终端设备发送第一指示信息,该第一指示信息承载在信令上。在本申请中,信令可以是无线资源控制(radio resource control,RRC)信令,也可以是下行控制信息(downlink control information,DCI),还可以是媒体接入控制(medium access control,MAC)层信令。具体的,网络设备可以向上述N个终端设备分别发送DCI,或者,网络设备可以发送一个公共(common)DCI,这个公共DCI是发送给小区内所有终端设备的,再或者,网络设备可以发送一个组公共(group common)DCI,这个组公共DCI是发送给上述N个终端设备的或发送给上述终端设备组的。
第一终端设备也可以通过与上述N个终端设备中除第一终端设备之外的其它N-1个终端设备协商确定上述N个终端设备中的每一个终端设备的数据在第一上行比特序列中的位置信息。然后,第一终端设备向网络设备发送第四指示信息,其中,第四指示信息包括上述N个终端设备中的每一个终端设备的上行数据在第一上行比特序列中的位置信息。具体的,第一终端设备发送第四指示信息的方式可以是显式的,例如,第四指示信息加在第一上行比特序列头部,与第一上行比特序列承载在相同的时频资源上,由第一终端设备一同发送给网络设备;或者,第四指示信息单独承载在第一预设时频资源上,由第一终端设备发送给网络设备。第一终端设备发送第四指示信息的方式也可以是隐式的,例如,第四指示信息可以部分隐式承载在解调参考信号(demodulation reference signal,DMRS)上。具体的,N个终端设备中的每一个终端设备发送的DMRS的循环移位索引隐式对应N个终端设备中的每一个终端设备的上行数据在第一上行比特序列中的聚合序号。在这种隐式的实现方式中,第一终端设备需要向网络设备发送第一上行比特序列中的每一个终端设备的上行数据的比特长度,该比特长度可以加在第一上行比特序列的头部,与第一上行比特序列一起发送给网络设备,或者,第一终端设备使用第二预设时频资源发送该比特长度。对应的,网络设备可以通过接收到的DMRS的循环移位索引确定每一个终端设备的聚合序号,再根据接收到的第一上行比特序列中的每一个终端设备的上行数据的比特长度,解析得到N个终端设备中的每一个终端设备的上行数据在第一上行比特序列中的位置信息。
S102、第一终端设备获取N个终端设备中的每一个终端设备的上行数据。
第一终端设备可以直接通过第一终端设备的MAC层获取到第一终端设备的上行数据。可以理解的是,这里的上行数据是待发送给网络设备的上行数据。第一终端设备如何获取到上述N个终端设备中除第一终端设备之外的终端设备的上行数据,下面以第一终端设备获取第二终端设备的上行数据为例进行说明,这里的第二终端设备为上述N个终端设备中除第一终端设备之外的终端设备。第二终端设备对第二终端设备的上行数据进行信道编码,并在第三 预设时频资源上使用第一预设传输参数广播上述信道编码后的数据。上述第三预设时频资源、第一预设传输参数可以是网络设备指示的,或者,由上述N个终端设备事先协商确定的。
第一终端设备在第三预设时频资源上接收第二终端设备广播的数据,并按照预设的传输参数恢复得到第二终端设备信道编码后的数据,然后对该信道编码后的数据进行信道译码,得到第二终端设备的上行数据。
第一终端设备除了获取N个终端设备中的每一个终端设备的上行数据之外,还可以获取N个终端设备中除第一终端设备之外的每一个终端设备的标识。以第一终端设备获取第二终端设备的标识为例,第二终端设备可以将第二终端设备的标识与第二终端设备的上行数据一起发送给第一终端设备;或者,第二终端设备可以使用第二终端设备的标识对第二终端设备的上行数据的循环冗余码校验(cyclic redundancy check,CRC)比特序列进行加扰并发送给第一终端设备,第一终端设备遍历N个终端设备中除第一终端设备之外的每个终端设备的标识对CRC比特序列进行解扰,解扰成功对应的终端设备的标识即为第二终端设备的标识。
S103、第一终端设备根据第一指示信息和N个终端设备中的每一个终端设备的上行数据确定第一上行比特序列。
具体的,第一终端设备可以根据第一指示信息、第三指示信息和N个终端设备中的每一个终端设备的上行数据确定第一上行比特序列。其中,第三指示信息是由网络设备通过信令发送给终端设备的,第三指示信息包括终端设备组中的每一个终端设备的标识与该终端设备在终端设备组中的索引的映射关系。上述终端设备组共有M个终端设备,M为大于等于N的整数。以M等于6为例,6个终端设备的标识分别为ID0、ID1、ID2、ID3、ID4和ID5,第三指示信息的体现方式如表1所示。其中,这里的索引可以是显式携带的,也可以是隐式对应的。
表1终端设备组中的每一个终端设备的标识
终端设备在终端设备组中的索引 终端设备的标识
0 ID0
1 ID1
2 ID2
3 ID3
4 ID4
5 ID5
上述第一指示信息为N个终端设备中的每一个终端设备的上行数据在第一上行比特序列中的位置信息。以M等于6,N等于4为例,N个终端设备对应的标识分别为ID0、ID2、ID4和ID5。第一指示信息的实现方式可以如表2所示。第一终端设备可以根据表2中终端设备在终端设备组中的索引和表1来共同确定终端设备的标识与终端设备的上行数据在第一上行比特序列中的位置信息的对应关系。第一终端设备再根据步骤S102中获取的N个终端设备中的每一个终端设备的上行数据与对应的终端设备的标识,确定N个终端设备中每一个终端设备的上行数据在第一上行比特序列中的位置,进而进行比特聚合,从而确定第一上行比特序列。
表2终端设备的索引和位置信息的对应关系
终端设备在终端设备组中的索引 终端设备的上行数据在第一上行比特序
  列中的位置信息
0 位置信息1
2 位置信息2
4 位置信息3
5 位置信息4
具体的,比特聚合的实现方式可以是第一终端设备根据N个终端设备中的每一个终端设备的上行数据在第一上行比特序列中的起始位置,或者,根据N个终端设备中的每一个终端设备的上行数据在第一上行比特序列中的结束位置,确定N个终端设备中的每一个终端设备的上行数据的比特长度,进而根据比特长度和起始位置或根据比特长度和结束位置进行比特聚合;比特聚合的实现方式还可以是第一终端设备根据每一个终端设备的上行数据的比特长度和聚合序号进行比特聚合。例如,当N等于4时,每个终端设备的聚合序号如表3所示。假设每一个终端设备的上行数据的比特长度为20字节,索引0对应的终端设备在第一上行比特序列中的位置为第1字节至第20字节,索引2对应的终端设备在第一上行比特序列中的位置为第21字节至第40字节,索引4对应的终端设备在第一上行比特序列中的位置为第41字节至第60字节,索引5对应的终端设备在第一上行比特序列中的位置为第61字节至第80字节。
表3终端设备索引、聚合序号和比特长度的对应关系
终端设备在终端设备组中的索引 聚合序号 比特长度
0 0 20字节
2 1 20字节
4 2 20字节
5 3 20字节
S104、网络设备向第一终端设备发送第二指示信息。
对应的,第一终端设备接收该第二指示信息,其中,第二指示信息包括第一时频资源的信息。第一时频资源为第一终端设备向网络设备发送N个终端设备的上行数据使用的时频资源。
在本实施例中,除了第一终端设备需要向网络设备发送N个终端设备的上行数据之外,其它N-1个终端设备也需要向网络设备发送N个终端设备的上行数据。假设第二终端设备为其它N-1个终端设备中的一个终端设备,第二终端设备向网络设备发送N个终端设备的上行数据的时频资源为第二时频资源。第一时频资源和第二时频资源之间可以完全重叠,或者部分重叠,或者完全不重叠。可以理解的是,第一终端设备在第一时频资源上发送的传输块大小与第二终端设备在第二时频资源上发送的传输块大小相同。
可选的,第二指示信息还可以包括第一传输参数,第一传输参数为第一终端设备发送第一上行比特序列的传输参数。第一传输参数与第二传输参数的取值可以相同也可以不同,第二传输参数为第二终端设备发送第一上行比特序列的传输参数,第二传输参数由第三指示信息指示。第一传输参数和第二传输参数可以包括调制与编码方案(modulation and coding scheme,MCS),还可以包括冗余版本(redundancy version,RV)、传输层编号和预编码矩阵中的至少一个。具体的,第二指示信息和第三指示信息可以是由DCI携带的。一种可能的实 现方式是第二指示信息和第三指示信息由不同的DCI携带,例如由第一终端设备和第二终端设备各自的UE特定的(UE-specific)DCI携带;另一种可能的实现方式是第二指示信息和第三指示信息是相同的DCI携带,例如由终端设备组对应的group common DCI携带。具体的,第一传输参数和第二传输参数可以包含RV,第一传输参数中的RV和第二传输参数中的RV可以相同或不同。当第一时频资源和第二时频资源部分重叠或完全重叠时,第一传输参数和第二传输参数还可以包含传输层编号和传输层总数,第一传输参数中的传输层编号与第二传输参数中的传输层编号可以不同;或者,第一传输参数和第二传输参数还可以包含预编码矩阵,第一传输参数中的预编码矩阵和第二传输参数中的预编码矩阵可以不同。
S105、第一终端设备对第一上行比特序列进行信道编码,得到第二上行比特序列。

具体的,第一终端设备根据第一传输参数将第二上行比特序列调制映射到第一时频资源上,并发送给网络设备。

可选的,网络设备在第一时频资源上接收来自第一终端设备的第二上行比特序列,网络设备在第二时频资源上接收来自第二终端设备的第三上行比特序列,其中,第三比特序列为第二终端设备对第一上行比特序列进行信道编码得到的。网络设备基于接收到的第二上行比特序列和第三上行比特序列进行信道译码,得到第一上行比特序列。
可选的,网络设备在第一时频资源上接收第二上行比特序列和第三上行比特序列,对接收到的比特序列进行信道译码,得到第一上行比特序列。
进一步的,网络设备根据N个终端设备中的每一个终端设备的上行数据在第一上行比特序列中的位置信息,获取每一个终端设备的上行数据。
在本实施例中,N个终端设备交互获得N个终端设备的上行数据,N个终端设备中的每一个终端设备对N个终端设备的上行数据按照一定的规则进行比特聚合,并对聚合后的比特序列进行信道编码,从而增加了编码前的序列长度,提高了编码增益。
