  • the present invention relates to the field of communications, and in particular to a method, device, and system for transmitting a communication channel.
  • the 5G communication system is also referred to as a "post 4G network” or a “post LTE (Long Term Evolution) system.
  • 5G communication systems are considered to be implemented in higher frequency bands (eg, above 3 GHz) in order to achieve higher data rates.
  • the characteristics of high-frequency communication are that it has relatively serious path loss and penetration loss, and its spatial transmission is closely related to the atmosphere. Due to the extremely short wavelength of the high-frequency signal, a large number of small antenna arrays can be applied, so that the beamforming technology can obtain a more accurate beam direction, and the advantages of the narrow beam technology can improve the coverage of the high-frequency signal and compensate for the transmission loss.
  • transmit beamforming and/or receive beamforming is used.
  • Transmit beamforming is generally a technique that uses multiple antennas to concentrate the signals transmitted by each antenna in a particular direction.
  • the combination of the plurality of antennas is referred to as an array antenna, and each antenna included in the array antenna is referred to as an antenna element.
  • the propagation of the signal is increased by the use of transmit beamforming, and since almost no signal is received in directions other than the relevant direction, interference to other users is significantly reduced.
  • Receive beamforming is a technique in which the reception of radio waves is concentrated in a specific direction by using a receiving antenna array in a receiver.
  • the signal sensitivity of the incoming signal in the relevant direction is increased by the use of receive beamforming, but the incoming signal in the direction other than the relevant direction is removed from the received signal, thereby preventing the interference signal.
  • the terminal may firstly perform the PDCCH decoding delay.
  • the PDSCH is received and saved, and can be used for decoding of the PDSCH after the PDCCH decoding is completed.
  • a terminal in a communication system using beamforming, a terminal often receives a downlink control channel and a data channel by using a beam. Since the control channel and the data channel have different transmission performance requirements, for example, the control channel often requires high transmission robustness. However, the data channel often requires higher transmission efficiency, and accordingly, the transmission scheme and the transmission/reception beam of the control channel and the data channel are not completely identical.
  • the channel corresponds to the control channel decoding delay in different receiving beams.
  • the control channel (PDCCH) is received by the beam 1
  • the data channel (PDSCH) scheduled by the control channel is received by the beam 2. Since there is only one data channel and one control channel, and one-to-one control, in this case, since the terminal cannot judge the receiving beam of the data channel before the control channel is completely decoded, the data channel cannot be blocked during the control channel decoding delay.

Description

通信信道的传输方法及装置、系统 技术领域
本发明涉及通信领域，具体而言，涉及一种通信信道的传输方法及装置、系统。
背景技术
为了满足自4G(第4代)通信系统的部署一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的5G(第5代)通信系统。5G通信系统也被称为“后4G网络”或“后LTE(Long Term Evolution，长期演进)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。
在使用波束成形技术的通信系统中，发送波束形成和/或接收波束形成被使用。发送波束形成一般而言是一种使用多个天线将每个天线发送的信号集中在特定方向上的技术。该多个天线的组合被称为阵列天线，并且阵列天线中包括的每个天线被称为天线元素。信号的传播由于使用发送波束成形而增大，并且因为除了相关方向以外的其它方向上几乎接收不到信号，所以对其它用户的干扰显著降低。接收波束成形是一种在接收器中通过使用接收天线阵列将对无线电波的接收集中在特定方向上的技术。在相关方向上进入的信号的信号灵敏度由于使用接收波束成形而增大，但在除了相关方向以外的方向上进入的信号被从接收信号中除去，从而阻止了干扰信号。
长期演进LTE系统中，由于终端对物理下行控制信道(PDCCH，Physical Downlink Control Channel)和物理下行共享信道(PDSCH，Physical Downlink Shared Channel)均采用全向接收，因此在PDCCH解码时延期间终端可以先将PDSCH接收并保存下来，待PDCCH解码完成后即可以用于PDSCH的解码。然而，在使用波束成形的通信系统中，终端往往采用波束的方式接收下行控制信道和数据信道，由于控制信道和数据信道对传输性能的要求不同，例如控制信道往往要求较高的传输鲁棒性，而数据信道则往往要求更高的传输效率，因此对应地，控制信道和数据信道的传输方案或发送/接收波束存在不完全相同的情况，图1是根据本发明相关技术的控制信道和数据信道对应不同接收波束下的控制信道解码时延示意图，如图1所示，控制信道(PDCCH)采用波束1进行接收，而由该控制信道调度的数据信道(PDSCH)却采用波束2进行接收。由于数据信道和控制信道都只有一个，并且是一对一控制的，这种情况下，由于控制信道未完全解码之前终端无法判断数据信道的接收波束，将造成控制信道解码时延期间数据信道无法准确接收的问题。
另外，5G或未来通信系统对链路通信的可靠性、实时性也提出了更高的要求，相关技术中的一个控制信道对应一个数据信道的方案，明显不能应对。
针对相关技术中的存在的上述问题，目前尚未发现有效的解决方案。

步骤S202，第一设备向第二设备发送N个控制信道，其中，N个控制信道用于指示M个数据块的传输配置信息，M和/或N为大于1的正整数。
通过上述步骤，第一设备向第二设备发送N个控制信道，其中，N个控制信道用于指示M个数据块的传输配置信息，M和/或N为大于1的正整数。由于第一设备和第二设备之间的控制信道多于一个，可以指示数据在不同的数据信道中传输，实现了多个控制信道对多个数据信道的并行管理，因此可以解决相关技术中在使用控制信道和数据信道传输数据时可靠性和实时性差的问题。提高了数据传输的可靠性，提供了更低时延的控制和数据信道。
可选地，上述步骤的执行主体第一设备可以为数据传输的一端，可以是网络侧设备，如基站，但也可以是终端等，但不限于此。

本实施例提出一种控制信道传输方法，包括以下步骤：
第一设备向第二设备发送N个控制信道，用于向第二设备指示M个数据块的传输配置信息。其中，M和/或N为正整数。

可选地，从控制信道和主控制信道可以采用不同的编码方案、编码效率、调制等级等。优选地，主控制信道的编码码率小于等于从控制信道的编码码率，这样做的好处是，使得主控制信道的传输鲁棒性更高一些。

优选地，M个子数据信道具有相同的发送方式和/或接收方式。其中，发送方式包括子数据信道发送所采用的发送波束/预编码权值/波束赋形权值、发送方案(单天线传输/传输分集/开环MIMO/闭环MIMO)、调制编码等级、解调参考信号中至少之一，接收方式包括接收子数据信道所采用的接收波束/(接收)预编码权值/(接收)波束赋形权值、接收方案(单天线接收/多天线分集接收、单波束接收/多波束接收、宽波束接收/窄波束接收)中至少之一。

实施例3
本实施例包括多个具体实施例，用于结合不同的场景对本申请进行详细说明：
具体实施例1
图6是本发明实施例中N个控制信道分别调度N个数据信道的示意图，如图6所示，基站向终端1(UE1)发送的数据业务被划分为N(图中N＝2)个数据块，分别用N个数据信道传输，并且在数据信道传输之前，基站向终端发送N个控制信道分别用于调度上述N个数据信道，即这N个控制信道分别用于向终端指示这N个数据信道的传输配置信息。其中，传输配置信息包括数据块的传输方案(例如单天线传输/传输分集/开环MIMO/闭环MIMO)、数据块传输所采用的发送/接收波束/预编码权值/波束赋形权值、数据块传输所占用的时域资源、数据块传输所占用的频域资源、数据块传输所采用的调制等级、数据块传输所采用的编码等级、数据块传输所采用的解调参考信号等。
N个控制信道中有一个是主控制信道，剩余的控制信道被称为从控制信道。主控制信道是必需的，从控制信道有些情况下有，有些情况下没有， 从控制信道的是否存在以及存在几个从控制信道受到主控制信道的控制。即基站通过主控制信道向终端通知是否存在从控制信道、存在几个从控制信道、从控制信道的时频资源位置等。从控制信道通常在时域上位于主控制信道之后，即通过在主控制信道发送之后才发送从控制信道。例如图6中，PDCCH 1为主控制信道，PDCCH 2为从控制信道，基站通过PDCCH 1向终端指示了具有1个从控制信道(PDCCH 2)以及从控制信道PDCCH2的时频资源位置等。
基站通过主控制信道PDCCH 1和从控制信道PDCCH 2分别向终端1指示基站向终端1发送的数据信道PDSCH 1和PDSCH 2的传输配置信息。具体地这里可能有两种方式，一种方式是主控制信道PDCCH 1和从控制信道PDCCH 2各分别独立指示PDSCH 1的传输配置信息和PDSCH 2的传输配置信息，即主控制信道PDCCH 1向终端1指示PDSCH 1的全部传输配置信息，从控制信道PDCCH 2向终端1指示PDSCH 2的全部传输配置信息，图7是本发明实施例中N个控制信道分别调度N个数据信道情况下N个控制信道与N个数据信道之间的一种对应关系的示意图，如图7所示；另一种方式是主要控制信道PDCCH 1指示数据信道PDSCH 1和PDSCH 2的公共的传输配置信息和PDSCH 1独有的传输配置信息，PDCCH 2仅指示PDSCH 2独有的传输配置信息，图8是本发明实施例中N个控制信道分别调度N个数据信道情况下N个控制信道与N个数据信道之间的另一种对应关系的示意图，如图8所示，例如主控制信道PDCCH 1向终端1指示PDSCH 1的传输方案(单天线传输/传输分集/开环MIMO/闭环MIMO)、PDSCH 1传输所采用的发送/接收波束/预编码权值/波束赋形权值、PDSCH 1所采用的调制编码等级、PDSCH 1所采用的解调参考信号、PDSCH 1所占用的时频资源，而PDCCH 2仅用于向终端1指示PDSCH 2所占用的时频资源，基站将PDSCH 2的其它传输配置信息(传输方案、发送/接收波束/预编码权值/波束赋形权值、调制编码等级、解调参考信号)配置成与PDSCH 1是相同的，即这些传输配置信息是PDSCH 1和PDSCH 2的公有传输配置信息，终端1通过接收PDCCH 1就可以获 得PDSCH 2的这些传输配置信息，再通过接收PDCCH 2获得PDSCH 2的独有的传输配置信息即时频资源位置信息，进而按照这些传输配置信息分别对PDSCH 1和PDSCH 2进行接收。
主控制信道PDCCH 1和从控制信道PDCCH 2的传输具有相同的发送方式和接收方式。这里的发送方式包括主控制信道和从控制信道传输所采用的发送波束/预编码权值/波束赋形权值、发送方案(例如单天线传输/传输分集/开环MIMO/闭环MIMO)、解调参考信号中至少之一。这里的接收方式包括主控制信道和从控制信道的接收波束/预编码权值/波束赋形权值、接收方案(例如单天线接收/多天线分集接收、单波束接收/多波束接收、宽波束接收/窄波束接收)中至少之一。基站为主控制信道PDCCH 1和从控制信道PDCCH 2配置相同的发送方式，终端默认按照相同的接收方式接收这两种控制信道。因而，这两种控制信道之间不存在解码延迟带来的从控制信道不能准确接收的问题。
作为本发明实施例的又一种实现方式，主控制信道发送之后，从控制信道也可以按照预先约定的发送方式进行发送，或者根据主控制信道的发送方式可以确定从控制信道的发送方式，或者主控制信道中向终端指示了从控制信道的发送方式。终端假设从控制信道和主控制信道采用相同的接收方式，即终端将采用与主控制信道相同的接收方式去接收从控制信道。例如，为了节省从控制信道所占用的资源，从控制信道可以按照预先定义的方式采用比主控制信道更高的调制编码速率、更简单的发送方案例如按照单天线或两天线传输分集进行发送。总的来说，从控制信道也可以采用与主控制信道不同的发送方式进行发送，但所采用的发送方式是基站和终端预先约定好的、或者跟主控制信道的发送方式有某种绑定关系、或者可以从接收到的主控制信道中的信息获得。
作为本发明实施例的又一种实现方式，控制信道所调度的数据信道也可以是上行数据信道。例如图6中的数据信道也可以是用于承载上行数据的物理上行共享信道(PUSCH，Physical Uplink Shared Channel)，图6中的下行控制信道承载上行授权信息(前面是下行授权信息)，用于指示终 端发送给基站的上行数据块的传输配置信息。或者N个控制信道所调度的N个数据信道中，既存在上行数据信道(PUSCH)又存在下行数据信道(PDSCH)。
具体实施例2
图9是本发明实施例中N个控制信道调度一个数据信道的示意图，如图9所示，基站向终端1(UE1)发送的数据业务用一个数据信道即一个PDSCH传输，并且在该数据信道传输之前，基站向终端1发送N(图9中N＝2)个控制信道(即图9中PDCCH1和PDCCH2)用于调度该数据信道PDSCH，即基站使用2个控制信道向终端1指示数据信道PDSCH的传输配置信息。其中，传输配置信息包括数据信道的传输方案(例如单天线传输/传输分集/开环MIMO/闭环MIMO)、数据信道传输所采用的发送/接收波束/预编码权值/波束赋形权值、数据信道传输所占用的时域资源、数据信道传输所占用的频域资源、数据信道传输所采用的调制等级、数据信道传输所采用的编码等级、数据信道传输所采用的解调参考信号等。
2个控制信道中PDCCH1为主控制信道，PDCCH2为从控制信道。主控制信道PDCCH1向终端1指示第一类传输配置信息，从控制信道PDCCH2向终端1指示第二类传输配置信息。其中，第一类传输配置信息便于终端1在数据信道区域并且在PDCCH2解码造成的延时期间至少能够先将对应的PDSCH部分接收并缓存起来，以便在PDCCH2解码完成之后，终端1按照PDCCH1和PDCCH2共同所指示的传输配置信息对PDSCH进行接收和解码。例如第一类传输配置信息中包括PDSCH传输所采用的发送/接收波束/预编码权值/波束赋形权值、PDSCH传输所占用的时频资源，而第二类传输配置信息中包括PDSCH的全部传输配置信息中的除第一类传输配置信息之外的剩余传输配置信息，例如包括PDSCH的传输方案(例如单天线传输/传输分集/开环MIMO/闭环MIMO)、PDSCH传输所采用的调制编码等级、PDSCH传输所采用的解调参考信号等。
主控制信道中还可以向终端指示是否存在从控制信道，在本实施例中 若主控制信道向终端指示了从控制信道的存在，基站和终端默认为从控制信道只有1个，即主控制信道中可以通过1比特向终端指示主控制信道之后是否存在从控制信道，例如比特值为0时向终端指示从控制信道个数为0，比特值为1时向终端指示从控制信道个数为1。
优选地，从控制信道和主控制信道采用相同的发送方式和接收方式，基站使用与主控制信道相同的发送方式发送从控制信道，终端假设从控制信道和主控制信道使用了相同的发送方式并使用与主控制信道相同的接收方式接收从控制信道。这里的发送方式包括主控制信道和从控制信道传输所采用的发送波束/预编码权值/波束赋形权值、发送方案(例如单天线传输/传输分集/开环MIMO/闭环MIMO)、解调参考信号中至少之一。这里的接收方式包括主控制信道和从控制信道的接收波束/预编码权值/波束赋形权值、接收方案(例如单天线接收/多天线分集接收、单波束接收/多波束接收、宽波束接收/窄波束接收)中至少之一。
作为本发明实施例的又一种实现方式，从控制信道也可以按照约定的发送/接收方式进行发送和接收，或者从控制信道的发送/接收方式和主控制信道的发送/接收方式之间存在某种约定的关系(或者称为绑定关系)，或者从控制信道的发送/接收方式直接通过主控制信道去指示。当从控制信道的发送/接收方式和主控制信道的发送/接收方式之间存在某种约定的关系，基站根据该约定关系确定从控制信道的发送方式，终端根据该约定方式获得从控制信道的发送方式信息并确定从控制信道的接收方式，按照该接收方式接收从控制信道。
作为本发明实施例的有一种实现方式，控制信道所调度的数据信道也可以是上行数据信道。例如图9中的数据信道也可以是用于承载上行数据的物理上行共享信道(PUSCH，Physical Uplink Shared Channel)，图9中的下行控制信道承载上行授权信息(前面是下行授权信息)，用于指示终端发送给基站的上行数据块的传输配置信息。
具体实施例3
图10是本发明实施例中N个控制信道调度M个数据信道的示意图，如图10所示，基站向终端1(UE1)发送的数据业务用M(图10中M＝4)个数据信道(PDSCH1～4)传输，并且在数据信道传输之前，基站向终端1发送N(图10中N＝2)个控制信道(即图10中PDCCH1和PDCCH2)用于调度4个数据信道，即基站使用2个控制信道向终端1指示数据信道PDSCH1～4的传输配置信息。其中，一个数据信道的传输配置信息包括该数据信道的传输方案(例如单天线传输/传输分集/开环MIMO/闭环MIMO)、数据信道传输所采用的发送/接收波束/预编码权值/波束赋形权值、数据信道传输所占用的时域资源、数据信道传输所占用的频域资源、数据信道传输所采用的调制等级、数据信道传输所采用的编码等级、数据信道传输所采用的解调参考信号等。
两个控制信道中PDCCH1为主控制信道，PDCCH2为从控制信道。将四个数据信道PDSCH1～4的所有传输配置信息划分为两部分，主控制信道PDCCH1向终端1指示第一部分传输配置信息，从控制信道PDCCH2向终端1指示第二部分传输配置信息。其中，这两部分传输配置信息之间交集为空，并集为四个数据信道PDSCH1～4的所有传输配置信息。例如，第一部分传输配置信息为M个数据信道的公有传输配置信息，第二部分传输配置信息为M个数据信道的专有传输配置信息的集合，或者第一部分传输配置信息为M个数据信道的公有传输配置信息和第一个数据信道的专有传输配置信息，第二部分传输配置信息为M个数据信道中除第一数据信道之外的M-1个数据信道的专有传输配置信息的集合。其中，所述公有传输配置信息包括数据信道的传输方案(单天线传输/传输分集/开环MIMO/闭环MIMO)、数据信道传输所采用的发送/接收波束/预编码权值/波束赋形权值、数据信道传输所采用调制等级、数据信道信道传输所采用的编码等级、数据信道传输所采用的解调参考信号中至少其中一项信息。
优选地，各个部分传输配置信息之间的交集也可以不为空，例如数据信道的一些重要传输配置信息可以在多个控制信道上重复传输，以提高这些传输配置信息的传输可靠性或鲁棒性。
主控制信道中还可以向终端指示是否存在从控制信道，在本实施例中若主控制信道向终端指示了从控制信道的存在，基站和终端默认为从控制信道只有1个，即主控制信道中可以通过1比特向终端指示主控制信道之后是否存在从控制信道，例如比特值为0时向终端指示从控制信道个数为0，比特值为1时向终端指示从控制信道个数为1。
优选地，从控制信道和主控制信道采用相同的发送方式和接收方式，基站使用与主控制信道相同的发送方式发送从控制信道，终端假设从控制信道和主控制信道使用了相同的发送方式并使用与主控制信道相同的接收方式接收从控制信道。这里的发送方式包括主控制信道和从控制信道传输所采用的发送波束/预编码权值/波束赋形权值、发送方案(例如单天线传输/传输分集/开环MIMO/闭环MIMO)、解调参考信号中至少之一。这里的接收方式包括主控制信道和从控制信道的接收波束/预编码权值/波束赋形权值、接收方案(例如单天线接收/多天线分集接收、单波束接收/多波束接收、宽波束接收/窄波束接收)中至少之一。
优选地，各个数据信道之间采用相同的发送方式和/或接收方式，基站将使用相同的发送方式发送各个数据信道，终端假设M个数据信道采用相同的发送方式，并使用相同的接收方式对这M个数据信道进行接收。这里的发送方式包括数据信道传输所采用的发送波束/预编码权值/波束赋形权值、发送方案(例如单天线传输/传输分集/开环MIMO/闭环MIMO)、解调参考信号中至少之一。这里的接收方式包括数据信道传输所采用的接收波束/预编码权值/波束赋形权值、接收方案(例如单天线接收/多天线分集接收、单波束接收/多波束接收、宽波束接收/窄波束接收)中至少之一。
作为本发明实施例的又一种实现方式，从控制信道也可以按照约定的发送/接收方式进行发送和接收，或者从控制信道的发送/接收方式和主控制信道的发送/接收方式之间存在某种约定的关系(或者称为绑定关系)，或者从控制信道的发送/接收方式直接通过主控制信道去指示。当从控制信道的发送/接收方式和主控制信道的发送/接收方式之间存在某种约定的关系，基站根据该约定关系确定从控制信道的发送方式，终端根据该约定方 式获得从控制信道的发送方式信息并确定从控制信道的接收方式，按照该接收方式接收从控制信道。
作为本发明实施例的有一种实现方式，控制信道所调度的数据信道也可以是上行数据信道。例如图6中的数据信道也可以是用于承载上行数据的物理上行共享信道(PUSCH，Physical Uplink Shared Channel)，图10中的下行控制信道承载上行授权信息(前面是下行授权信息)，用于指示终端发送给基站的上行数据块的传输配置信息。或者M个数据信道中，既存在上行数据信道(PUSCH)又存在下行数据信道(PDSCH)。
具体实施例4
图11是本发明实施例中一个控制信道调度M个数据信道的示意图，如图11所示，基站向终端1(UE1)发送的数据业务用M(图11中M＝4)个数据信道(PDSCH1～4)传输，并且在数据信道传输之前，基站向终端1发送N(图11中N＝1)个控制信道(即图11中PDCCH)用于调度4个数据信道，即基站使用1个控制信道向终端1指示数据信道PDSCH1～4的传输配置信息。
其中，每个数据信道的传输配置信息包括该数据信道的传输方案(例如单天线传输/传输分集/开环MIMO/闭环MIMO)、数据信道传输所采用的发送/接收波束/预编码权值/波束赋形权值、数据信道传输所占用的时域资源、数据信道传输所占用的频域资源、数据信道传输所采用的调制等级、数据信道传输所采用的编码等级、数据信道传输所采用的解调参考信号等。
这四个数据信道的传输配置信息可能具有相同或不同的发送方式和/或接收方式。图12是本发明实施例中一个控制信道调度M个数据信道且M个数据信道具有相同的发送波束的示意图，例如图12所示，这四个数据信道采用相同的发送波束发送，图13是本发明实施例中一个控制信道调度M个数据信道且M个数据信道具有不同的发送波束的示意图，而如图13所示，这四个数据信道分别采用不同的发送波束发送。
控制信道所采用的发送方式和接收方式可能跟数据信道所采用的发送/接收方式相同，也可能不同。例如图12中，控制信道采用与数据信道相同的发送波束发送，而当数据信道分别采用不同的发送波束发送，而控制信道只有一个时，控制信道只能采用更宽的波束发送，而且该宽波束的覆盖范围包括每个数据信道的发送波束的覆盖范围，例如图13中，控制信道采用与数据信道不同的发送波束发送，而且控制信道的波束宽度要比单个数据信道的波束宽度宽。
优选地，若这四个数据信道的传输配置信息很多都是一样的，例如数据信道的传输方案(例如单天线传输/传输分集/开环MIMO/闭环MIMO)、数据信道传输所采用的发送/接收波束/预编码权值/波束赋形权值数据信道传输所采用的调制等级、数据信道传输所采用的编码等级、数据信道传输所采用的解调参考信号等，控制信道只需要对四个数据信道传输一套传输参数配置信息即可，只是将四个数据信道独立所具有的传输配置信息再分别进行指示，例如至少需要对四个数据信道的时频资源需要独立进行指示。
在接收端，由于UE1的数据业务被划分为四个数据信道进行传输(PDSCH1～4)，UE1在接收到控制信道(PDCCH)的指示信息之后，可以分别对四个数据信道独立进行解码，因此先传输的数据信道将先被解码出来，而不必等到所有的数据信道都被接收到才开始进行解码。
作为本发明实施例的有一种实现方式，控制信道所调度的数据信道也可以是上行数据信道。例如图10中的数据信道也可以是用于承载上行数据的物理上行共享信道(PUSCH，Physical Uplink Shared Channel)，图10中的下行控制信道承载上行授权信息(前面是下行授权信息)，用于指示终端发送给基站的上行数据块的传输配置信息。或者M个数据信道中，既存在上行数据信道(PUSCH)又存在下行数据信道(PDSCH)。
具体实施例5
图14是本发明实施例中N个控制信道中L类控制信道调度M个数据 信道的示意图，如图14所示，基站向终端1(UE1)发送的数据业务被划分为M(图14中M＝2)个数据信道，用N(N＝6)个控制信道传输。其中，6个控制信道中共包含两类控制信道，前N/2(＝3)个控制信道为第一类控制信道，后N/2(＝3)个控制信道为第二类控制信道。优选地，前3个控制信道为PDCCH1以相同波束或不同波束重复发送了3次，后3个控制信道为PDCCH2以相同波束或不同波束重复发送了3次。在本发明实施例中，前N/2(＝3)个控制信道用于向UE1指示其第一个数据信道的传输配置信息，后N/2(＝3)个控制信道用于向UE1指示其第二个数据信道的传输配置信息。
作为本发明的实施例的又一种实现方式，前N/2(＝3)个控制信道也可以用于指示M个数据信道的传输配置信息中的第一部分传输配置信息，后N/2(＝3)个控制信道用于指示这M个数据信道的传输配置信息中的第二部分传输配置信息。其中，这M个数据信道的传输配置信息优选地指这M个数据信道各自的传输配置信息的并集；这M个数据信道的传输配置信息被划分为了两部分，其中这两部分传输配置信息之间交集为空，并集为这M个数据信道的传输配置信息。本发明实施例中的第一类控制信道(前N/2(＝3)个控制信道)向终端指示这M个数据信道的第一部分传输配置信息，第二类控制信道(后N/2(＝3)个控制信道)向终端指示这M个数据系电脑的第二部分传输配置信息。
当前/后3个控制信道以相同波束重复发送时，接收端可以采用不同的接收波束接收，以提高接收性能；当前/后3个控制信道以不同波束重复发送时，接收可以采用相同或不同的接收波束接收，这时控制信道的传输鲁棒性、覆盖范围通过在发送端的重复发送获得了提升。
具体实施例6
当N个控制信道包括N1个主控制信道和N-N1个从控制信道时，分别为主控制信道和从控制信道独立配置解调参考信号资源，即分别为主控制信道和从控制信道配置第一解调参考信号资源和第二参考信号资源。优选 地，所述第一解调参考信号资源在时域上位于主控制信道之前，所述第二解调参考信号在时域上位于从控制信道之前。图15是本发明实施例中N个控制信道M个数据块的解调参考信号配置第一示意图，图16是本发明实施例中N个控制信道M个数据块的解调参考信号配置第二示意图，例如图15/16所示，N＝2且N1＝1，假设PDCCH1为UE1的主控制信道，PDCCH2为UE1的从控制信道。则PDCCH1和PDCCH2分别具有独立配置的解调参考信号资源，并且解调参考信号在时域上分别位于对应的控制信道的前面，例如图15/16中，控制信道第一参考信号位于PDCCH1之前，而控制信道第二参考信号资源位于PDCCH2之前。接收端首先接收解调参考信号资源，通过控制信道解调参考信号估计PDCCH1传输信道信息，并对PDCCH1进行接收和解调，同理通过控制信道解调参考信号估计PDCCH2传输信道信息，并对PDCCH2进行接收和解调。通常控制信道与对应的解调参考信号资源采用相同的发送波束/预编码权值/波束赋形权值。
当N个控制包括L类控制信道时，分别为L类控制配置独立的解调参考信号资源，即为L类控制信道中第i类控制信道配置第i解调参考信号资源。优选地，第i解调参考信号资源在时域上位于所述第i类控制信道之前。图17是本发明实施例中N个控制信道M个数据块的解调参考信号配置第三示意图，图18是本发明实施例中N个控制信道M个数据块的解调参考信号配置第四示意图，例如图17/18所示，N＝6且L＝2，假设PDCCH1为第一类控制信道中的任意一个控制信道，PDCCH2为第二类控制信道中的任意一个控制信道，则为第一类控制信道(3个PDCCH1)和第二类控制信道(3个PDCCH2)分别配置独立的解调参考信号资源，即控制信道第一参考信号和控制信道第二参考信号资源，所有的第一类控制信道共享第一参考信号资源，所有的第二类控制信道共享第二参考信号资源，控制信道第一参考信号资源位于第一类控制信道之前，控制信道第二参考信号位于第二类控制信道之前。接收端首先接收接收参考信号资源，通过控制信道解调参考信号估计第一类控制信道的传输信道信息，并对第 一类控制信道进行接收和解调，同理通过控制信道解调参考信号估计第二类控制信道的传输信道信息，并对第二类控制信道进行接收和解调。优选地，同一类控制信道中的所有控制信道以相同波束进行发送时，为该类控制信道配置的解调参考信号的发送波束与该类控制信道的相同。作为本发明实施例的又一种实施方式，当位于同一类控制信道的所有控制信道以不同波束进行发送时，该类中的控制信道需要配置独立的参考信号资源，图19是本发明实施例中N个控制信道M个数据块的解调参考信号配置第五示意图，如图19所示，每个控制信道分别配置独立的解调参考信号资源，即第i个控制信道配置控制信道第i参考信号资源，且参考信号资源在时域上的位置位于对应的控制信道之前，如第一参考信号资源位于第一个控制信道(第一个PDCCH1)之前，第二参考信号资源位于第二个控制信道(第二个PDCCH1)之前，第三参考信号资源位于第三个控制信道(第三个PDCCH1)之前，第四参考信号资源位于第四个控制信道(第一个PDCCH2)之前，以此类推。
为所述M个数据块/数据信道配置一个解调参考信号资源，即这M个数据块/数据信道共享同一个解调参考信号资源。优选地，所述解调参考信号资源在时域上位于所述M个数据块/数据信道之前。例如图15/17所示，UE1的两个数据信道PDSCH1和PDSCH2共享一个解调参考信号资源，即仅为UE1的两个数据信道配置一个解调参考信号资源，且该参考信号资源在时域上位于这两个数据信道之前。UE1首先接收数据信道解调参考信号资源，通过该解调参考信号资源对这两个数据信道的传输信道进行估计，并对这两个数据信道进行接收和解调。优选地，这两个数据信道具有相同的发送波束，且该解调参考信号的发送波束与这两个数据信道的发送波束相同。
为所述M个数据块/数据信道分配配置独立的解调参考信号资源，即为所述M个数据块/数据信道中的第j个数据块/数据信道配置第j解调参考信号资源。优选地，所述第j解调参考信号资源在时域上位于所述第j个数据块/数据信道之前。例如图17/18所示，UE1的两个数据信道PDSCH1 和PDSCH2配置独立的解调参考信号资源，为PDSCH1配置数据信道第一参考信号资源，为PDSCH2配置数据信道第二参考信号资源，且数据信道第一参考信号资源位于PDSCH1之前，数据信道第二参考信号资源位于PDSCH2之前。UE1首先接收参考信号资源，根据接收到的第一参考信号资源对PDSCH1的传输信道进行估计，并对PDSCH1进行接收和解调，根据接收到的第二参考信号资源对PDSCH2的传输信道进行估计，并对PDSCH2进行接收和解调。优选地，这两个数据信道具有不同的发送波束，数据信道第一参考信号资源的发送波束与PDSCH1的发送波束相同，数据信道第二参考信号资源的发送波束与PDSCH的发送波束相同。
