Description

通信信道的传输、接收方法、装置、基站及终端 技术领域
本公开涉及通信领域，具体而言，涉及一种通信信道的传输、接收方法、装置、基站及终端。
背景技术
为了满足自4G(第4代)通信系统的部署以来增加的对无线数据业务的需求，已经进行努力来开发改善5G(第5代)通信系统。5G通信系统也被称为“后4G网络”或“后长期演进(Long Term Evolution，简称为LTE)系统”。
5G通信系统被认为是在更高频带(例如，3GHz以上)中实施，以便完成更高的数据速率。高频通信的特点在于具有比较严重的路损、穿透损耗，在空间传播与大气关系密切。由于高频信号的波长极短，可以应用大量小型天线阵，以使得波束成形技术能够获得更为精确的波束方向，以窄波束技术优势提高高频信号的覆盖能力，弥补传输损耗，是高频通信的一大特点。
在LTE系统中，下行物理控制信道主要包括两种，一种是终端公有的，另一种是终端专有的。终端公有的控制信道主要用于向终端指示一些公有的信息，例如，系统消息、随机接入授权消息等，它能被本小区内所有终端接收。终端专有的控制信道主要用于向终端指示一些终端专有的信息，它只能被目标终端接收。在LTE中，终端公有的控制信道采用全向发送，终端专有的控制信道采用全向或定向发送，其中，定向发送是通过数字预编码的方式实现的。在每个调度时间单元上，终端通过盲检测的方式接收物理下行控制信道，即终端需要在每个调度时间单元的前几个符号中尝试接收并解调控制信道。
在LTE系统中，下行物理控制信道一个重要的作用是用于向终端指示数据信道的传输相关信息。在LTE中，数据信道也是采用全向或定向发送，其中，定向发送是通过数字预编码的方式实现的。
在5G通信系统中，引入了混合预编码的结构，即同时采用数字预编码和模拟波束赋形技术对控制信道、数据信道进行传输。混合预编码结构下，一个射频链路在同一个时候只能发送一个波束，因此，在多波束情况下，需要多个时间上对多个不同波束方向进行扫描，才能完成控制信道或数据信道的全向或准全向发送。这增加了通信信道传输的资源开销。另外，与LTE相比，在相等的时间间隔内，调度时间单元的数量成倍增加，控制信道盲检测的复杂度也成倍增加。
因此，在相关技术中，通信信道的传输存在资源开销大，接收复杂度高的问题。

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，本申请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。
方法实施例
本申请实施例一所提供的方法实施例可以在移动终端、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是本公开实施例的一种通信信道的接收方法的移动终端的硬件结构框图。如图1所示，移动终端10可以包括一个或多个(图中仅示出一个)处理器102(处理器102可以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)、用于存储数据的存储器104、以及用于通信功能的传输装置106。本领域普通技术人员可以理解，图1所示的结构仅为示意，其并不对上述电子装置的结构造成限定。例如，移动终端10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可用于存储应用软件的软件程序以及模块，如本公开实施例中的通信信道的接收方法对应的程序指令/模块，处理器102通过运行存储在存储器104内的软件程序以及模块，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。在一些实例中，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。
传输装置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。在一个实例中，传输装置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。在一个实例中，传输装置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。
由于5G通信系统的设计对时延的要求更高，因此，在3GPP的讨论中已经提出支持多种子载波间隔、符号长度设计，即5G通信系统能够支持更短的正交频分复用(Orthogonal Frequency Division Multiplexing，简称为OFDM)符号、更短的调度时间单元设计。
5G通信系统的设计面向更多场景、能够满足各种需求，因此在3GPP的讨论中提出支 持多级下行控制信道，用于兼顾对控制信道鲁棒性和频谱效率的不同层次的需求。然而，如何平滑地实现多级下行控制信道之间的切换、以及如何合理地设计多级下行控制信道与数据信道的资源复用以最大程度地节省资源开销同时保证传输性能是需要考虑的一个问题。
针对上述通信信道传输的资源开销大、盲检测复杂度高、复用效率低的问题，尚未提出有效的解决方法，在本实施例中，提出了一种通信信道的传输和指示方法。
在本实施例中提供了一种运行于基站的通信信道的传输方法，图2是根据本公开实施例的通信信道的传输方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，传输第一通信信道，其中，通过第一通信信道的传输方式和/或第一通信信道所承载的信令指示以下信息至少之一：终端调度信息，第二通信信道的传输方式。
通过上述步骤，在传输第一通信信道时，指示终端调度指示信息和第二通信信道的传输方式信息，有效地解决了在相关技术中，通信信道的传输存在资源开销大，接收复杂度高的问题，从而达到了有效降低资源开销，而且也能够有效降低对通信信道的接收复杂度。
可选地，上述步骤的执行主体可以为基站、也可以是类似基站的网络控制实体等，但不限于此。需要说明的是，在图2中以基站向终端发送上述步骤S202为例进行说明。
其中，上述终端调度信息可以包括：终端分组信息，其中，终端分组信息包括一个或多个终端分组的指示信息。
可选地，这里的终端调度信息指终端被调度或未被调度的指示信息。可选地，终端调度信息为终端分组信息，其中，终端分组信息中包括一个或多个终端分组的指示信息。
例如，这里的终端分组信息可以包括一个或多个终端分组的组索引指示信息，用于指示当前或指定的持续时间内调度或未被调度到的终端分组。
当前或指定的持续时间内调度到的终端分组，指当前或指定的持续时间内基站将可能会对这些终端分组内的终端发送控制信道及数据业务，终端在当前或指定的持续时间内需要尝试接收控制信道及数据业务；
当前或指定的持续时间内未被调度到的终端分组，指当前或指定的持续时间内基站将不会对这些终端分组内的终端发送控制信道及数据业务，终端将不会在当前或指定的持续时间内接收控制信道及数据业务。
可选地，终端调度信息包括当前的调度时间单元内或者指定的一段时间单元内的终端分组信息。可选地，指定的一段时间单元包括指定的调度时间单元、从当前的调度时间单元开始的指定的持续时间段、或者从指定的时间开始并且指定的持续时间段。可选地可选地，指定的时间单元、指定的一段时间单元、指定的调度时间单元、指定的时间持续时间段可通过第一通信信道所承载的信令和/或高层信令指示给终端。其中，调度时间单元包括一个或多个时间单元，时间单元为时隙、子帧、帧、OFDM符号、或者微时隙。
例如，终端分组信息可以包括以下至少之一：当前的调度时间单元内的终端分组信息；指定的调度时间单元内的终端分组信息；从当前的调度时间单元开始的指定的持续时间段内的终端分组信息；从指定的调度时间单元开始并且指定的持续时间段内的终端分组信息。
在此需要说明的是，本公开实施例中所描述的“时间单元”与“调度时间单元”具有以下关 系，一个时间单元可以为一个OFDM符号、一个时隙、一个微时隙、一个子帧或者一个帧，一个调度时间单元则可以包括一个或多个时间单元。
可选地，上述方法还包括：按照预定义(或预先约定的方式)的方式对终端进行分组。需要说明的是，对终端进行分组可以由基站来执行，也可以由终端来执行。
预定义的方式包括：按照如下公式之一对终端进行分组：
公式一：UE_ID mod M＝i；
公式二：(UE_ID mod M+Offset)mod M＝i；
公式三：Offset mod M＝i。
其中，UE_ID表示终端标识，M表示共有M个分组并且M的值为非负整数，参数Offset的取值是可配置的，i∈{0～M-1}表示将终端标识为UE_ID的终端划分到第i个分组。这里的终端标识是区别于其它终端的唯一标识，例如，LTE中由16位二级制比特序列组成。可选地，M为大于1的整数。这里M的值可以是通过基站指示给终端的，例如，有些情况下M的值等于1即不对终端进行分组，有些情况下M的值大于1即需要对终端进行分组处理。M的值也可以是基站和终端预先约定好的。
需要说明的是，将M个分组的索引定义为0～M-1，主要是为了方便描述和区别不同的分组，实际上M的分组的索引也可以定义为其它的方式，只要能区分不同的分组就可以，例如M个分组的索引分别为1～M，这时i∈{0～M-1}表示将终端标识为UE_ID的终端划分到第i+1个分组。
可选地，上述参数Offset为取值范围为{0～M-1}的整数，参数Offset的默认的取值为0。当终端接收到参数Offset的指示信息时，终端按照所指示的Offset的值确定终端所属分组，当未接收到参数Offset的指示信息时，终端默认Offset的值为0。
预定义的方式也可以包括：按照终端能力对终端进行分组，其中，终端能力可以包括终端的带宽能力、终端的波束能力、终端所能支持的业务类型中至少之一。其中，终端能力和终端分组之间存在预定义的对应关系。可选地，这里的带宽能力指终端所能支持的最大频域带宽，这里的波束能力指终端能同时发出的波束个数或者终端所能支持的最大射频链路(有时也叫TXRU)个数，这里的业务类型至少包括eMBB(enhanced Mobile Broadband，增强的移动宽带)、URLLC(Ultra-Reliable and Low Latency Communications，低时延高可靠连接)、eMTC(massive Machine Type Communications，大规模物联网)等。
可选地，通过第一通信信道的传输方式指示第二通信信道的传输方式可以采用多种方式，例如，可以采用以下方式：第一通信信道的传输方式和第二通信信道的传输方式之间存在预定义的对应关系。这里的第一通信信道的传输方式和第二通信信道的传输方式可以指相同或不同的传输方式参数，例如，第一通信信道的传输方式和第二通信信道的传输方式均指传输方案，即第一通信信道的传输方案和第二通信信道所采用的传输方案之间存在对应关系，可选地第二通信信道所采用的传输方案为一个传输方案的可选范围；又例如第一通信信道的传输方式指聚合级别，而第二通信信道的传输方式指调制编码等级(Modulation and Coding Scheme，简称为MCS)，即第一通信信道的聚合级别和第二通信信道的调制编码等 级之间存在预定义的对应关系，可选地，第二通信信道所对应的调制编码等级为一个调制编码等级的可选范围。
在上述的通信信道的传输和指示方法中，可以由第一通信节点向第二通信节点传输第一通信信道，通过第一通信信道的传输方式和/或所承载的信令指示终端调度信息、第二通信信道的传输方式信息中至少之一。
可选地，第一通信信道可以为控制信道或者广播信道，第二通信信道可以为控制信道或者数据信道，例如，第一通信信道为控制信道时，控制信道包括：公有控制信道，或者，多个终端共享的控制信道。需要说明的是，这里的控制信道可选地为终端专有的控制信道。第二通信信道与第一通信信道可以位于不同的调度时间单元中，第二通信信道也有可能和第一通信信道是同一种类型的通信信道，极端情况下，第二通信信道就是第一通信信道。例如，第一通信信道是控制信道，第二通信信道是数据信道；第一通信信道是公有控制信道，第二通信信道是终端专有的控制信道；第一通信信道和第二通信信道均为终端专有的控制信道，且同对应同一个终端的同一个控制信道。

这种类型的控制信道(第一通信信道)可以支持自动传输请求(Hybrid Automatic Repeat reQuest，简称为HARQ)机制，例如，在第二通信信道发送之前接收第一通信信道的ACK/NACK确认信息，其中ACK表示第一通信信道被正确接收，NACK表示第一通信信道没有被正确接收。
基站根据接收的ACK信息或者NACK信息，传输第二通信信道，其中，当接收到ACK信息时，根据第一控制信道的指示传输第二通信信道，当接收到NACK信息时，根据第二控制信道的指示传输第二通信信道，其中第一控制信道为第一通信信道，第二控制信道为区别于第一控制信道的其它的控制信道。

例如，当基站接收到ACK信号之后，基站将按照增强的控制信道所指示的传输方式信息传输数据信道，当接收到NACK信息之后，基站将按照基本的控制信道所指示的传输方式信息传输数据信道。对于终端来说，当它向基站反馈ACK信号时，终端将按照第一通信信道的指示接收第二通信信道，当它向基站反馈NACK信号时，终端将按照其它类型的控制信道的指示接收第二通信信道。
这种类型的控制信道(第一通信信道)可以和第二通信信道共享一套DMRS图样的部分DMRS资源。可选地，共享的解调参考信号资源既可以用于解调第一通信信道，也可以用于解调第二通信信道，而非被共享的解调参考信号资源只能用于解调第二通信信道或第一通信信道。DMRS图样满足以下设计原则：共享的解调参考信号资源位于第一通信信道区域，解调参考信号资源中除被共享的解调参考信号资源之外的解调参考信号资源位于第二通信信道区域；或者，共享的解调参考信号资源位于第一通信信道传输的资源开始位置，解调参考信号资源中除共享的解调参考信号资源之外的解调参考信号资源位于第二通信信道传输的资源开始位置。假设第一通信信道支持的最大传输层数为P层，第二通信信道支持的最大传输层数为W层，其中P和W均为正整数，且P的值小于W，于是DMRS图样中的前P个端口(例如，假设解调参考信号端口定义为端口[0,7]，则前P个端口为[0,P-1]，P小于解调参考信号资源总的端口数即P小于8)为第一通信信道和第二通信信道共享的DMRS端口，剩余W-P个端口为第二通信信道专有的DMRS端口。终端可以支持多套DMRS图样，当第一通信信道在第二通信信道区域传输时采用上述DMRS图样，否则采用其它DMRS图样。其中，其它图样为区别于上述图样的不同图样，例如，其它DMRS图样为用于第二通信信 道的DMRS端口均在第二通信信道区域的开始位置处。

步骤2：UE接收到分组信息之后，根据分组规则判断自己是否在所接收到的分组内，若是，在当前或当前一段时间内尝试接收终端专有的控制信道，若否，则在当前或当前一段时间内不尝试接收终端专有的控制信道。
可选地，UE分组的规则包括以下之一，假设需要将UE划分为M个组：
规则1：根据UE标识(Identity，简称为ID)进行UE分组，例如，若UE ID对M取模后的值为i，则将该UE分配到第i组中；
规则2：根据UE ID和配置的参数进行UE分组，例如，通过公式(UE ID mod M+Offset)mod M＝i，则将该UE分配到第i组中，其中，Offset的取值是可配置的，例如，可以通过广播信道、同步信号、高层信令等指示给终端。可选地Offset的取值范围为{0～M-1}，当终端未接收到Offset的配置指示时，终端默认为Offset的值为0；
规则3：根据配置的参数进行进行UE分组，例如，若参数UE_ID_v对M取模后的值为i，则将该UE分配到第i组中，其中，参数UE_ID_v是基站配置给终端的，参数UE_ID_v的取值是可配置的，例如，可以通过广播信道、同步信号、高层信令等指示给终端。可选地，参数UE_ID_v的取值范围为{0～M-1}，当终端未接收到Offset的配置指示时，终端默认为参数UE_ID_v的值为0；

作为本公开实施例的又一种实现方式，通过公有或者终端组公有的控制信道也可以指示上述时域范围内未调度到的分组信息，这时，当UE接收到分组信息之后，根据分组规则判断自己是否在所接收到的分组内，若是，在当前或当前一段时间内不尝试接收终端专有的控制信道，若否，则在当前或当前一段时间内尝试接收终端专有的控制信道。

终端获得调度时间单元图样之后，仅在指示可用于传输公有下行控制信道的时间单元上尝试接收公有下行控制信道，在其它调度时间单元上不尝试接收公有下行控制信道。

下行控制信道支持两级下行控制信道，其中第一级下行控制信道的传输配置相对固定，其资源配置是预先约定好的活着通过半静态信令配置的，采用更为鲁棒的传输方案进行传输，例如，空频块码(Space Frequency Block Code，简称为SFBC)；第二级下行控制信道的传输配置更为灵活，其资源配置可以是由第一级控制信道指示的，并且支持频谱效率更高的传输方案，例如，单用户多输入多输出(Single User-Multiple-Input Multiple-Output，简称为SU-MIMO)。第一级下行控制信道位于下行控制信道区域传输，第二级控制信道可位于数据信道区域传输。
由于第二级控制信道的信道环境和数据信道都位于数据信道区域，因此第二级控制信道的传输方式与数据信道之间往往存在对应关系。这种对应关系可以是基站和终端预先约定好的。
假设第二级控制信道支持最大为2层的SU-MIMO传输、SFBC、循环延迟分集(Cyclic Delay Diversity，简称为CDD)，而数据信道支持最大为8层的SU-MIMO传输、SFBC、CDD，第二级控制信道传输方案与数据信道传输方案之间存在如下的对应关系：
当第二级USS采用SU-MIMO(2层)传输时，物理下行共享信道(Physical Downlink Shared Channel，简称为PDSCH)对应的传输方案范围为SU-MIMO(5～8层)；
当第二级USS采用SU-MIMO(1层)传输时，PDSCH对应的传输方案范围为SU-MIMO(1～4层)；
当第二级USS采用SFBC传输时，PDSCH对应的传输方案范围为{SFBC、CDD、SU-MIMO(1～2层)}。
基站通过第二级控制信道的传输方案确定PDSCH对应的传输方案范围，并且根据信道测量反馈信息从传输方案范围中选择一个传输方案进行当前数据信道的传输，并将所选择的传输方案信息通过第二级控制信道中承载的信令指示给终端；基站通过第二级控制信道的传输方案确定PDSCH对应的传输方案范围，并从接收到的第二级控制信道中承载的信令指示确定PDSCH当前所采用的传输方案，然后接收并解调PDSCH。其中，第二级控制信道可以通过2比特信令向终端指示所选择的传输方案。
作为本公开实施例的又一种实施方式，第二级控制信道的调制编码方式与数据信道的调制编码方式之间存在对应关系。
作为本公开实施例的又一种实施方式，第二级控制信道的聚合级别和数据信道的调制编码方式之间存在对应关系。

优选实施例4
下行控制信道支持两级下行控制信道，其中，第一级下行控制信道的传输配置相对固定，其资源配置是预先约定好的活着通过半静态信令配置的，采用更为鲁棒的传输方案进行传输，例如，SFBC；第二级下行控制信道的传输配置更为灵活，其资源配置可以是由第一级控制信道指示的，并且支持频谱效率更高的传输方案，例如，SU-MIMO。第一级下行控制信道位于下行控制信道区域传输，第二级控制信道可位于数据信道区域传输。
由于第二级控制信道的信道环境和数据信道都位于数据信道区域，因此第二级控制信道与数据信道之间可以共享一套DMRS图样。但是考虑到数据信道也支持SU-MIMO传输，然而，由于控制信道传输对鲁棒性的要求更高，通常第二级下行控制信道SU-MIMO下所支持的最大传输层数小于数据信道所支持的最大传输层数。因此，该DMRS图样中的部分资源可位于第二级下行控制信道传输的开始位置，部分资源位于数据信道传输的开始位置。其中，位于第二级下行控制信道传输开始位置处的DMRS资源中包括控制信道和数据信道的共享DMRS端口，该共享DMRS端口既可用于解调第二级下行控制信道，又可以用于解调数据信道。
图5是本公开优选实施例提供的第二级控制信道和数据信道共享部分DMRS端口的DMRS图样示意图，如图5所示，假设一个DMRS图样中支持8个端口，编号分别为{0～7}，其中，第二级控制信道最多支持2层传输，数据信道最多支持8层传输，那么DMRS图样中的8个端口的前2个端口(port 0～1)为第二级控制信道和数据信道共享的端口，后6个端口(port 2～7)为数据信道专有的端口。因此，为了控制信道和数据信道的解码时延最优同时信道估计性能最好，将共享的DMRS端口(port 0～1)置于控制信道传输的开始位置，将数据信道专有的DMRS端口(port 2～7)置于数据信道传输的开始位置。可选地，控制信道和数据信道的复用采用TDM的方式。
终端接收到前两个DMRS端口(port 0～1)后，尝试解调控制信道和数据信道，在接收到后六个DMRS端口(port 2～7)后，尝试解调数据信道。
作为本公开实施例的又一种实现方式，支持多套DMRS图样，当有第二级控制信道在数据区域传输时，采用上述DMRS图样，否则当没有第二级控制信道在数据区域传输时，DMRS图样中的所有DMRS端口位于数据区域的开始位置。
优选实施例5
下行控制信道支持两级下行控制信道，其中，第一级下行控制信道的传输配置相对固定，其资源配置是预先约定好的活着通过半静态信令配置的，采用更为鲁棒的传输方案进行传输，例如，SFBC；第二级下行控制信道的传输配置更为灵活，其资源配置可以是由第一级控制信道指示的，并且支持频谱效率更高的传输方案，例如，SU-MIMO。第一级下行控制信道位于下行控制信道区域传输，第二级控制信道可位于数据信道区域传输。
为了同时保证第二级下行控制信道的鲁棒性，以及基站基于第一级控制信道和第二级控制信道之间的自适应切换。第二级控制信道支持HARQ机制。
图6是本公开优选实施例提供的对第二级控制信道进行ACK/NACK反馈的流程示意图，如图6所示，在跨时隙(slot)调度中，基站在slot n中的下行控制(Downlink Control，简称为DC)区域发送第二级下行控制信道，同时在该slot中的上行控制(Uplink Control，简称为UC)区域向基站反馈针对第二级下行控制信道的ACK/NACK信息，当基站接收到终端反馈的ACK信息时，基站正常在slot n+1上按第二级下行控制信道的指示发送数据，终端也对应地按照第二级下行控制信道的指示对数据信道进行解调、解码；当基站接收到NACK信息时，基站将按照第一级下行控制信道(在slot n之前发送或在slot n+1上发送)的指示发送数据，终端也对应地按照第一级下行控制信道的指示对数据信道进行解调、解码。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开各个实施例的方法。
