Description

控制信道的发送方法和装置、接收方法和装置 技术领域
本发明涉及通信领域，具体而言，涉及一种控制信道的发送方法和装置、接收方法和装置。
背景技术
传统的蜂窝网系统主要采用低频段(例如300MHz至3GHz)频谱，然而，随着通信业务需求的不断增长，传统的低频段变得越来越拥挤，已经不足以满足未来通信的需求。因此，将高频频谱资源用于移动宽带通信已经成为未来网络发展的趋势。
高频通信的特点在于具有比较严重的路损、穿透损耗，高频信号的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，以使得波束赋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。
长期演进(Long Term Evolution，简称为LTE)系统中，终端对物理下行控制信道采用每个子帧(即1毫秒)盲检测的方式进行监听和接收。然而在高频通信系统中，由于基本传输单元非常小，通常是微秒(us)级别，因此，如果终端对控制信道的检测仍然采用盲检测的方式，其接收复杂度过大，从而影响了控制信道的传输，造成控制信道的传输效率较低。
针对相关技术中由于终端对控制信道采用盲检测的方式造成的控制信道的传输效率较低的技术问题，目前尚未提出有效的解决方案。

图2是根据本发明实施例的控制信道的发送方法的流程图，如图2所示，该方法包括如下步骤：
步骤S201，第一设备获取控制信道的第一类发送资源的资源信息。
上述的控制信道是指用于传输控制信息的物理信道。
步骤S202，第一设备根据第一类发送资源的资源信息确定控制信道的第二类发送资源,其中,第二类发送资源为预先定义的且不同于第一类发送资源的发送资源。
步骤S203，第一设备在第一类发送资源和第二类发送资源上向第二设备发送控制信道。
通过上述实施例，第一设备获取控制信道的第一类发送资源的资源信息；第一设备根据第一类发送资源的资源信息确定控制信道的第二类发送资源,第二类发送资源为不同于第一类发送资源的发送资源；第一设备在第一类发送资源和第二类发送资源上向第二设备发送控制信道，从而解决了相关技术中由于终端对控制信道采用盲检测的方式造成的控制信道的传输效率较低的技术问题，实现了提高控制信道的传输效率的技术效果。
需要说明的是，第一设备为控制信道的发送端，第二设备为控制信道的接收端，例如，在蜂窝网下同下行链路传输中，第一设备为基站，对应地第二设备为终端；在蜂窝网系统上行链路传输中，第一设备为终端，对应地第二设备为基站；在设备与设备(Device to Device，简称为D2D) 通信中，第一设备为终端1，对应地第二设备为终端2。
在上述实施例中，第一类发送资源包括以下至少之一：实际用于发送控制信道的第一发送波束；备选的用于发送控制信道的第二发送波束，也即可用于发送控制信道的发送波束；实际用于传输控制信道的第一解调参考信号资源；备选的用于传输控制信道的第二解调参考信号资源，也即可用于传输控制信道的解调参考信号。
上述的第一解调参考信号资源包括以下至少之一：第一解调参考信号端口；第一解调参考信号序列；产生第一解调参考信号序列的参数；第一解调参考信号所占用的时域资源；第一解调参考信号所占用的频域资源。第二解调参考信号资源包括以下至少之一：第二解调参考信号端口；第二解调参考信号序列；产生第二解调参考信号序列的参数；第二解调参考信号所占用的时域资源；第二解调参考信号所占用的频域资源。第一发送波束通过以下信息中的至少之一进行表征：第一发送波束的标识；第一发送波束所在波束组的标识；第一发送波束对应的预编码；第一发送波束对应的波束赋形权值。第二发送波束通过以下信息中的至少之一进行表征：第二发送波束的标识；第二发送波束所在波束组的标识；第二发送波束对应的预编码；第二发送波束对应的波束赋形权值。
需要说明的是，控制信道的发送波束是指控制信道经过预编码或波束赋形权值的加权之后发送出去的波束，不同的预编码权值或波束赋形权值对应不同的发送波束。
可选地，二类发送资源包括以下至少之一：控制信道的时域资源位置；控制信道的时域持续时长；控制信道的频域资源位置；控制信道的频域持续带宽；控制信道的码域资源。
上述的控制信道的码域资源是指控制信道信息比特的传输中加入了一些码域的信息，例如，正交掩码(Orthogonal Cover Code，简称为OCC)等，不同的码域资源可以用于传输不同的控制信道。
具体地，控制信道的时域资源位置包括控制信道的时域开始位置和/ 或时域结束位置；控制信道的频域资源位置包括控制信道的频域开始位置和/或频域结束位置。
在步骤S201中，第一设备获取控制信道的第一类发送资源的资源信息包括：第一设备接收来自于第二设备的反馈信息，其中，反馈信息中携带有第一类发送资源的资源信息。
具体地，第一设备接收来自于第二设备的反馈信息包括：第一设备发送测量参考信号至第二设备，其中,测量参考信号用于测量第一设备和第二设备之间的信道质量；第一设备接收来自于第二设备的用于反馈信道质量的反馈信息，其中，反馈信息中携带有第一类发送资源的资源信息。
在第一设备获取控制信道的第一类发送资源的资源信息之后，第一设备可将第一类发送资源的资源信息通过信令通知给第二设备，其中，信令包括高层信令、广播信令以及物理层控制信令中的至少之一。
具体地，控制信道的第一类发送资源可以根据信道测量或波束训练或波束扫描或波束跟踪过程获得的。通常，控制信道是用于指示数据信道的调度(例如，数据信道占用的时频资源、数据信道传输所采用的调制编码等级、数据信道传输分集或复用方案的指示等)，因此，在控制信道发送之前通常会有信道测量或波束训练或波束扫描或波束跟踪的过程，以辅助基站进行用户数据的调度。第二设备根据信道测量结果获得控制信道的第一类发送资源并将其反馈给第一设备；或者第二设备根据信道测量结果获得控制信道的第一类发送资源的推荐值(也即备选资源)并将其反馈给基站，基站根据实际情况从备选资源中选择控制信道的第一类发送资源，并将该第一类发送资源信息通知给第二设备，其中，第一设备发送控制信道之前，网络侧可以通过信令(例如，高层信令或广播信令或其它物理层控制信道)将第一类发送资源信息通知给第二设备。
需要说明的是，在反馈信息中：为不同的第一发送波束设置有不同的优先级；为不同的第二发送波束设置有不同的优先级；为不同的第一解调参考信号资源设置有不同的优先级；为不同的第二解调参考信号资源设置 有不同的优先级。也即，若反馈信息中携带有多个第一发送波束的信息，则将其中优先级最高的第一发送波束作为实际的发送波束；同理，对于第一解调参考信号资源也是如此。在确定第二发射资源时，根据第一发射资源中优先级最高的资源(如优先级最高的第一发送波束、优先级最高的第一解调参考信号资源)确定对应的第二发射资源。
在步骤S202中，第一设备根据第一类发送资源的资源信息确定控制信道的第二类发送资源包括：基于第一类发送资源和第二类发送资源的预设关系，第一设备根据第一类发送资源的资源信息确定对应的第二类发送资源，其中，预设关系为第一设备与第二设备预先约定的或由网络侧通过信令指示给第一设备和/或第二设备的。
上述的预设关系可以为一一对应关系或者多对一的关系或者一对多的关系，一一对应关系是指第一类发送资源中的一个单位资源对应于第二类发送资源中的一个单位资源，多对一的关系是指第一类发送资源中的多个单位资源对应于第二类发送资源中的一个单位资源，一对多的关系是指第二类发送资源中的多个单元资源对应于第一类发送资源中的一个单元资源。
上述的预设关系也可以为预定义的函数关系，其中，函数关系用于根据第一类发送资源确定第二类发送资源。
具体地，控制信道的第一类发送资源与第二类发送资源之间具有固定的对应关系。其中，该对应关系为预先定义的，或者由第一设备和第二设备预先约定好的，或者由网络侧通过信令通知给第一设备和第二设备。具体的对应关系包括：控制信道的发送波束或备选发送波束或解调参考信号或备选解调参考信号(即上述第一类发送资源中的一个单位资源)与发送控制信道时频资源(即上述的第二类发送资源中的一个单位资源)之间具有一一对应的关系；或者该控制信道的发送波束或备选发送波束或解调参考信号或备选解调参考信号与发送该控制信道的时频资源之间为多对一的对应关系。
另外，控制信道的第一类发送资源和第二类发送资源之间可通过某种函数关系的方式确定，该函数是预先定义好的，例如，控制信道资源索引可以由该控制信道的波束标识带入该函数关系来确定，当然，该函数关系的输入参数中可能不只有控制信道的波束标识，还与其它的一个或一些参数有关，例如，用户标识(UE identity，简称为UE ID)等。
对于接收端的第二设备而言，接收端(即第二设备)根据控制信道的第一类发送资源确定第二类发送资源，并在该第一类发送资源和第二类发送资源上接收控制信道。这里包括根据控制信道的第一类发送资源确定第二类发送资源的可选范围，以便接收端在该可选范围中按照盲检测的方式接收它的控制信道。
第二设备将第一类发送资源反馈给第一设备时，同时将第一类发送资源中(例如，不同的发送波束或备选发送波束或解调参考信号或备选解调参考信号)的资源按照不同优先级进行排列，即所反馈的第一类发送资源中不同的资源具有不同的优先级，该优先级信息一并被包含在第二设备反馈给第一设备的第一类发送资源中。
发送端(也即第一设备)接收到携带优先级信息的第一发送资源信息之后，就可以按照优先级顺序为控制信道选择其实际发送波束或解调参考信号；接收端根据第一类发送资源确定第二类发送资源时，就可以根据第一类发送资源中优先级从高到低的顺序依次确定第二类发送资源或第二类发送资源的可选范围，尝试接收控制信道。一旦在某一个第一类发送资源和对应的第二类发送资源中检测到了该接收端的控制信道，则不再在剩余的第一类发送资源和其对应的第二类发送资源中尝试接收控制信道。从而完成对控制信道的接收。由此降低接收端的接收复杂度。
下面结合具体的实施方式详述本申请的实施例：
实施方式1
每个发送波束分别绑定一个控制信道时频资源。
如图3和图4(包括图4a、图4b以及图4c)所示，假设基站共有8 个发送波束(分别为波束0至波束7)可用于发送控制信道，第i个发送波束的编号或波束标识(Beam identity，简称为Beam ID或波束ID)为i，其中i为小于8的整数。
基站为下行控制信道传输预留N个时频资源，其中，N的值等于可用于发送下行控制信道的发送波束个数，即N＝8，8个发送波束与8个下行控制信道时频资源之间具有一一对应关系。该对应关系为预定义的(即由基站和终端预先约定好的)，或者由基站通过信令(例如，高层信令和广播信令等)通知给终端。图4a、图4b、图4c分别给出了三种下行控制信道资源(即图4中示出的资源0至资源7)和其发送波束(Beam0至Beam7)之间的对应关系示意图，在图4a中，不同下行控制信道资源以时分的方式进行划分，即在时域上进行划分，在图A中，不同下行控制信道资源以频分的方式进行划分，即在频域上进行划分，在图4c中，不同下行控制信道资源以时频混合的方式进行划分，不同的控制信道发送波束按照固定顺序分别与不同的下行控制信道资源一一对应。值得注意的是，图4a至图4c给出的对应顺序只是其中一个例子，发送波束与控制信道资源的对应关系顺序不限于上述方式。不同的控制信道资源，可以是按照时域、频域以及码域中至少之一的资源进行划分。
需要说明的是，在图4a至图4c中，时域轴表示控制信道资源，频域轴表示业务带宽，不同的控制信道资源对应不同的波束，例如Beam0对应于资源0等。
终端测量下行信道状态质量信息，并将所测得的下行信道状态信息或者根据该下行信道状态信息获得的与该终端对应的下行控制信道的优选发送波束(或称之为备选发送波束)信息反馈给基站，于是，基站获得与该终端对应的下行控制信道的第一类发送资源信息，即备选发送波束信息。
基站接收到备选发送波束信息之后，直接将备选发送波束作为控制信道的发送波束，并在该备选发送波束所对应的控制信道资源上将该下行控制信道发送出去，或者基站根据调度情况(例如，控制信道的传输方案、 其它用户是否已经占用了该备选发送波束中的波束)从该备选发送波束中选择出作为控制信道的发送波束，并在该选择出的发送波束所对应的控制信道资源上将控制信道通过这些波束发送出去。
终端侧根据控制信道的发送波束确定控制信道的接收资源。若基站直接将备选发送波束作为控制信道的发送波束将控制信道发送出去，则终端根据发送波束与控制信道资源的对应关系，直接确定控制信道资源，并在这些资源上接收控制信道；若基站按照某种规则从备选发送波束中选择其中某个或某一些发送波束将控制信道发送出去，则终端先根据发送波束与控制信道的对应关系确定控制信道资源可能范围，例如备选发送波束为1、2和3，则控制信道资源的可能范围为控制信道资源1、控制信道资源2和控制信道资源3，终端在这些资源上监听和盲检测控制信道。
需要说明的是，上述控制信道资源上仅允许发送控制信道，或者在未被任何控制信道占用的控制信道资源上允许发送其它的信道或信号，例如，在这些资源上允许发送数据信道。
可选地，若基站按照某种规则从备选发送波束中选择其中某个或某一些发送波束将控制信道发送出去，并且将该选择出的发送波束信息指示给终端，则终端可以直接根据选择出的发送波束确定控制信道的发送资源，并在该资源上接收控制信道。其中，基站选择出的发送波束信息在该控制信道发送之前指示给终端，例如，可以通过高层信令或广播信令或物理层控制信令指示给终端。具体地，若控制信道为第二级控制信道，在该控制信道发送之前还存在第一级控制信道，该第一级控制信道的其中一个作用就是向终端指示第二级控制信道的一些发送信息，例如发送波束信息。
可选地，上述发送波束与控制信道资源的对应关系也可以等效地由控制信道的解调参考信号资源与控制信道资源的对应关系代替。例如，基站共有8个发送波束可用于发送控制信道，其中，不同的发送波束对应不同的控制信道解调参考信号资源，不同的解调参考信号资源对应不同的控制信道资源。解调参考信号资源包括解调参考信号端口、解调参考信号序列、 产生解调参考信号序列的参数、解调参考信号所占时频资源中至少之一。
实施方式2
多个发送波束绑定一个共同的控制信道时频资源。
如图5(包括图5a、图5b以及图5c)所示，假设基站共有M个发送波束可用于发送下行控制信道，其中，第i个发送波束变化或波束标识(beam identity，简称为Beam ID或波束ID)为i，i为小于M的整数。
基站为下行控制信道传输预留N个下行控制信道资源，其中，N的值小于可用于发送下行控制信道的发送波束个数，即N<M。基站的M个发送波束与N个下行控制信道资源之间具有固定的对应关系，该对应关系为预定义的、或由基站和终端预先约定好的、或者由基站通过信令(例如，高层信令和广播信令等)通知给终端。图5a、图5b、图5c分别给出了M＝16和N＝4情况下基站的发送波束(Beam0至Beam15)与下行控制信道发送资源(资源0至资源3)之间的对应关系示意图。在图5a中，不同下行控制信道资源以时分的方式进行划分，在图5b中，不同下行控制信道资源以频分的方式进行划分，在图5c中，不同下行控制信道资源以时频混合的方式进行划分，不同的控制信道发送波束按照固定的划分方式划分为不同的组，分别与不同的下行控制信道发送资源一一对应。值得注意的是，图5a至图5c中给出的发送波束组划分方式以及与下行控制信道资源的对应顺序只是其中的一个例子，发送波束组的划分以及与控制信道资源的对应顺序不限于以上方式。不同的控制信道资源，可以是按照时域、频域、码域其中至少之一的资源进行划分。
需要说明的是，在图5a至图5c中，时域轴表示控制信道资源，频域轴表示业务带宽，不同的控制信道资源对应不同的波束组，例如Beam0至Beam3(即图5中的Beam 0～3)对应于资源0等。
终端测量下行信道状态质量信息，并将所测得的下行信道状态信息或者根据该下行信道状态信息获得的与该终端对应的下行控制信道的优选发送波束(或称之为备选发送波束)信息反馈给基站，于是基站获得与该 终端对应的下行控制信道的第一类发送资源信息，即备选发送波束信息。
基站接收到备选发送波束信息之后，直接将备选发送波束作为控制信道的发送波束，并在该备选发送波束所对应的控制信道资源上将该下行控制信道发送出去，或者基站根据调度情况(例如，控制信道的传输方案、其它用户是否已经占用了该备选发送波束其中的波束)从该备选发送波束中选择出作为控制信道的发送波束，并在该选择出的发送波束所对应的控制信道资源上将控制信道通过这些波束发送出去。
终端侧根据控制信道的发送波束确定控制信道的接收资源。若基站直接将备选发送波束作为控制信道的发送波束将控制信道发送出去，则终端根据发送波束与控制信道资源的对应关系，直接确定控制信道资源，并在这些资源上接收控制信道，例如若控制信道备选发送波束为波束3和4，则终端将在控制信道资源0和资源1上盲检测控制信道；若基站按照某种规则从备选发送波束中选择其中某一个或某一些发送波束将控制信道发送出去，则终端先根据发送波束与控制信道的对应关系确定控制信道资源范围，例如备选发送波束为3和4，基站为终端选择出的用于发送控制信道的波束为波束3，则终端将在与波束3对应的控制信道资源即控制信道资源0上监听并接收该终端的控制信道。
需要说明的是，上述控制信道资源上仅允许发送控制信道，或者在未被任何控制信道占用的控制信道资源上允许发送其它的信道或信号，例如在这些资源上允许发送数据信道。
可选地，若基站按照某种规则从备选发送波束中选择其中某个或某一些发送波束将控制信道发送出去，并且将该选择出的发送波束信息指示给终端，则终端可以直接根据选择出的发送波束确定控制信道的发送资源，并在该资源上接收控制信道。其中，基站选择出的发送波束信息在该控制信道发送之前指示给终端，例如可以通过高层信令或广播信令或物理层控制信令指示给终端。具体地，若控制信道为第二级控制信道，在该控制信道发送之前还存在第一级控制信道，该第一级控制信道的其中一个作用就 是向终端指示第二级控制信道的一些发送信息，例如发送波束信息。
可选地，上述发送波束与控制信道资源的对应关系也可以等效地由控制信道的解调参考信号资源与控制信道资源的对应关系代替。例如，基站共有16个发送波束可用于发送控制信道，其中不同的发送波束对应不同的控制信道解调参考信号资源，不同的解调参考信号资源对应不同的控制信道资源。其中，解调参考信号资源包括解调参考信号端口、解调参考信号序列、产生解调参考信号序列的参数、解调参考信号所占时频资源中至少之一。
实施方式3
反馈信息中包括具有优先级排列第一类发送资源。
终端测量下行信道状态质量信息，并将所测得的下行信道状态信息或者根据该下行信道状态信息获得的与该终端对应的下行控制信道的备选发送波束信息，并将备选发送波束以某种准则按照不同的优先级进行排列，例如，按照不同发送波束下的接收SINR(全称为Signal to Interference and Noise Ratio)的好坏或者吞吐量或容量的高低等准则对这些发送波束进行优先级从高到低的排列，并将进行排列之后的备选发送波束信息反馈给基站，于是基站获得与该终端对应的下行控制信道的具有优先级排列的第一类发送资源信息(即备选发送波束信息)。
基站接收到该备选发送波束信息之后，根据备选发送波束的优先级从高到底确定用于控制信道的发送波束，同时考虑其它用户调度情况，例如其它用户已经占用了该备选发送波束中的优先级最高的发送波束(即最优的发送波束)，则基站将选择备选发送波束中的次优的发送波束作为控制信道的实际发送波束，并通过该波束将控制信道发送出去。
基站的M个发送波束与N个下行控制信道资源之间具有固定的对应关系，其中该对应关系为预定义的、或由基站和终端预先约定好的、或者由基站通过信令(例如高层信令和广播信令等)通知给终端。例如图5a给出了M＝16和N＝4情况下基站的发送波束与下行控制信道发送资源之间的 对应关系示意图。不同的控制信道发送波束按照固定的划分方式划分为不同的组，分别与不同的下行控制信道发送资源一一对应。
接收端侧由于未获得控制信道的实际发送波束的信息，将直接根据测量获得的备选发送波束确定控制信道的接收资源，并且根据备选发送波束的优先级排列，终端将按照备选发送波束优先级从高到低的顺序在对应的控制信道接收资源上监听并盲检测该终端的控制信道。例如，若控制信道的备选发送波束为波束3和4，并且波束3的优先级高于波束4，则终端将首先在波束3所对应的控制信道接收资源即资源0上监听并盲检测该终端的控制信道，若在该资源上接收到该终端的控制信道，则不再在波束4所对应的控制信道资源上监听并盲检测该终端的控制信道，否则若在资源0上没有接收到该终端的控制信道，则将在波束4所对应的控制信道资源即资源1上监听并盲检测该终端的控制信道。
通过上述实施例，通过预定义第一类发送资源和第二类发送资源之间的关系，从而可以快速根据第一类发送资源确定第二类发送资源，完成对控制信道的发送，提高了控制信道的发送效率。
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，本发明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)执行本发明各个实施例所述的方法。

具体地，第二设备发送反馈信息至第一设备包括：第二设备在接收到第一设备的指示测量信道质量的测量参考信号时，发送用于反馈信道质量的反馈信息至第一设备，其中,测量参考信号用于测量第一设备和第二设备之间的信道质量。
