Description

数据发送方法、数据接收方法及装置 技术领域
本申请涉及移动通信领域，尤其涉及数据发送方法、数据接收方法及装置。
背景技术
在频分复用的场景下，每一个小区的系统带宽会被划分为多个传输子带，每个传输子带可以独立进行数据传输。由于用户设备在一个小区内的位置并非固定不动，因此为满足数据传输的需求，还需要随着小区内用户设备发生移动、切换等情况变化，对每小区内的传输子带的数量进行半静态或动态调整。
由于在进行数据传输时，每一个传输子带都关联一个模拟波束，因此在小区内的传输子带数量发生半静态或动态变化时，模拟波束的数量及每一个模拟波束所关联的传输子带也会随之发生变化。例如，如图1所示，小区内的模拟波束数目可以随着用户的移动半静态变化，在时刻1小区内可支持的模拟波束数目为4，B1，B2，B3，B4这四个模拟波束各关联一个传输子带，每个传输子带各为1/4的系统带宽；而时刻2时小区内可支持的模拟波束数目变为3，B1，B2，B3这三个模拟波束中每个模拟波束各关联一个传输子带，每个传输子带各为1/3的系统带宽；而时刻三时小区内可支持的模拟波束数目变为2，B2，B3这两个模拟波束中每个模拟波束各关联一个传输子带，每个传输子带各为1/2的系统带宽。
由于在控制信息传输过程中，每一个模拟波束对应一份待传输的控制信息。如果模拟波束的数量或模拟波束所关联的传输子带发生变化，那么会导致该小区用于发送控制信息的频域资源变化。因此在频分复用的场景下，如果模拟波束的数量或模拟波束所关联的传输子带发生变化，那么用户设备需要首先确定用于发送控制信息的频域位置，才能完成控制信息的数据传输。

具体实施方式
在本申请各个实施例中，基站可以包括节点B(NodeB)、演进的节点B(evolved NodeB，简称eNodeB)等用于发送数据的发送设备；用户设备可以包括移动台(mobile station,简称MS)，用户设备(user equipment，简称UE)等用于接收数据的接收设备。
在本申请各个实施例中，传输子带由基站的系统带宽按照预定规则划分而成，每一个传输子带与一份控制信息指示或一份控制信息相对应，用于发送相应的控制信息指示或控制信息。在基站可支持的最大模拟波束数量下，每一个模拟波束所对应的子带为基本子带，每一个传输子带的带宽都大于或者等于一个基本子带的带宽。
例如，如果基站可支持的最大模拟波束数量为4，那么在模拟波束数量为4的情 况下，每一个模拟波束所对应的子带为一个基本子带，那么所述系统带宽就包括4个基本子带，而传输子带则可以为1至4个。

下面结合附图对本申请的内容做进一步说明。
参见图2，为本申请数据发送方法一个实施例的流程示意图，该方法包括如下步骤：
步骤201，在预定的指示数据传输时间单元，基站发送N份控制信息指示。
基站可以在预定的指示数据传输时间单元发送N份控制信息指示，每一份控制信息指示占用各自所对应的至少一个传输子带，N为正整数。N的取值可以由无线通信系统或无线通信协议预先设定，也可以由基站在每次发送控制信息指示时，根据控制信息指示的传输需求在预先设定的范围内选定，即，所述基站可以在每次需要发送控制信息指示时，都发送相同份数的控制信息指示，或者，也可以在每次需要发送控制信息指示时，都发送不同份数的控制信息指示。
例如，当N取值被预先设定为4时，基站可以每次都发送4份控制信息指示。当预先设定的范围为1至4时，基站可以根据需要发送1至4份控制信息指示，并且每次发送的控制信息指示份数都可以各不相同。
由于在实际使用中，可用于传输所述控制信息指示的传输子带的数量通常是有限的，因此N的取值除需要大于或等于1之外，还会小于或等于预定值T，即1≤N≤T，其中，T即为预设可用于传输所述控制信息指示的传输子带的最大数量。由于每一个模拟波束需要占用至少一个基本子带，因此T的取值小于或等于所述基站所支持的最大模拟波束数量。
通常情况下，T的取值可以与所述基站所支持的最大模拟波束数量相同，N的取值则可以与T的取值相同。基站在发送所述控制信息时，每份所述控制信息占用所述T个传输子带中的至少一个。例如，当所述基站所支持的最大模拟波束数量为4时， T的取值可以为4，即，基站每次可以发送最多4份控制信息指示。
所述指示数据传输时间单元可以是每子帧的前P个符号，P≥1。例如，指示数据传输时间单元可以是频分双工(frequency division duplexing，简称FDD)下行子帧的第1个符号，或者也可以是时分双工(time division duplexing，简称TDD)的特殊子帧的第1个符号。可选地，所述指示数据传输时间单元与控制信息传输时间单元可以相同或不同。优选地，所述预定义的指示数据传输时间单元可以为控制信息传输时间单元之前预定义的P个时间单元。
所述控制信息指示，可以用于指示控制信息的份数M及传输每份所述控制信息分别所用的时频资源。其中，1≤M≤N，即，所述基站在进行数据传输时，其所发送的控制信息的份数要小于或等于其所发送的控制信息指示的份数。
除此之外，所述控制信息指示，还可以用于指示传输每一份所述控制信息所占用传输子带的数量，及每一份控制信息所占用的传输子带的子带信息。
可选的，所述控制信息指示，还可以用于指示每一份所述控制信息所占用的时间单元。其中，所述控制信息所占用的时间单元，可以是所述控制信息指示传输所占用的时间单元，也可以是所述指示数据传输时间单元之后的时间单元。即，基站可以在同一个时间单元内发送控制信息指示及控制信息，也可以在不同的时间单元内发送控制信息指示及控制信息。例如，基站可以在每个子帧的前P个符号发送控制信息指示，并在除前P个符号之外的其他符号发送控制信息；或者，基站也可以在每个子帧的前P个符号同时发送控制信息指示及控制信息。
步骤202，所述基站使用所述时频资源，分别发送对应的所述控制信息。
在所述控制信息指示发送完成后或在发送所述控制信息指示的同时，所述基站还可以使用所述时频资源发送所述控制信息。
例如，当基站可以支持的最大模拟波束数目为4时，T的取值通常也为4。即，在基站可以支持的最大模拟波束数目为4时，基站可以使用4个传输子带发送控制信息指示及控制信息。
在T的取值为4时，N的取值则可以为1至4之间的任意整数。即，基站可以发送1至4份的控制信息指示，每一份所述控制信息指示可以占用所述4个传输子带中的至少一个。通常情况下，基站可以发送4份控制信息指示，其中每一份控制信息指示可以占用一个传输子带。
当基站使用4个传输子带分别发送4个控制信息指示时，根据需要可以使用所述4个传输子带发送1至4份的控制信息。当需要发送三份控制信息时，基站可以使用两个传输子带发送其中一份控制信息，并各使用一个传输子带发送其余两份控制信息。当需要发送两份控制信息时，可以各使用两个传输子带发送每份控制信息；也可以使用三个传输子带发送一份控制信息，并使用另一个传输子带发送另一份控制信息。
相应的，当需要发送三份控制信息时，所述控制信息指示可以指示所述控制信息的份数为3，并可以指示每一份控制信息所占用的传输子带以及每一个传输子带的频域位置。除此之外，所述控制信息指示还可以指示3份控制信息所占用的时域资源，即，所述控制信息指示可以分别指示3份控制信息在哪些时间单元中传输。
采用本实施例所提供的方法，可以在发送控制信息之前首先发送控制信息指示，通过控制信息指示指示每一份控制信息的时频资源，从而使用户设备可以根据控制信息指示的指示内容确定用于发送控制信息的时频资源。
与图2所述的数据发送方法相对应，本申请还提供了数据接收方法。
参见图3，为本申请数据接收方法一个实施例的流程示意图。该方法可以由用户设备执行。如图2所示，所述方法可以包括：
步骤301，用户设备接收N份控制信息指示。
用户设备首先接收N份控制信息指示，每一份控制信息指示占用各自所对应的至少一个传输子带。其中，每一份所述控制信息指示都可以用于指示控制信息的份数M及传输每份所述控制信息分别所用的时频资源。
由于控制信息指示的份数可以由无线通信系统或无线通信协议预先设定，也可以由基站在预先设定的范围内选定，因此，根据控制信息指示份数的确定方式不同，用户设备可以采用不同的方式确定每一份所述控制信息指示所占用的第一时频域资源。
当控制信息指示的份数由无线通信系统或无线通信协议预先设定时，所述用户设备可以根据预设的控制信息指示份数，确定基站传输每一份所述控制信息指示所用的第一时频域资源；然后在所述第一时频域资源上接收所述基站发送的所述控制信息指示。其中，预设的控制信息指示份数即为所述设备发送控制信息指示时所发送的控制信息指示的预设置份数。
例如，当N的取值为4，即基站固定使用4个传输子带分别发送4份控制信息指 示时，用户设备可以根据系统带宽及4个传输子带所对应的预定传输子带划分规则确定每一个传输子带的频域位置；然后接收基站通过对应传输子带发送的控制信息指示。
当控制信息指示的份数由基站在预先设定的范围内选定时，所述用户设备在可用于传输所述控制信息指示的传输子带中盲检获得所述N份控制信息指示。其中，所述控制信息指示的份数的最大数量T为预设值。在T的取值及系统带宽确定后，可能传输控制信息指示的传输子带的数量及每一个传输子带的子带信息随之也可以确定，从而使用户设备通过盲检确定控制信息指示的频域位置，并完成控制信息指示的接收。
例如，当控制信息指示份数的最大值为4时，基站可以根据实际需求发送1至4份的控制信息指示，其中，每一份控制信息指示对应一个传输子带。用户设备在接收控制信息指示时，可以首先确定基站在发送1至4份的控制信息指示这四种情况的每种情况下，每份控制信息指示分别可能对应的传输子带的候选频域位置(候选频域位置通常是固定的)，然后盲检这些可能的候选频域位置，通过盲检确定控制信息指示的份数及每一份控制信息指示所对应传输子带的频域位置。
步骤302，所述用户设备根据所述控制信息指示的指示，接收与所述用户设备相对应的控制信息。
在接收到所述控制信息指示之后，用户设备可以根据所述控制信息指示确定对应的控制信息所占用传输子带的数量，以及所述控制信息所占用的传输子带的信息。根据控制信息所占用传输子带的数量及传输子带的信息，用户设备确定控制信息的频域位置。
在接收到所述控制信息指示之后，用户设备还可以根据所述控制信息指示确定所述控制信息所占用的数据传输时间单元。其中，控制信息所占用的数据传输时间单元与控制信息指示所占用的数据传输时间单元可以是同一个时间单元也可以是不同的时间单元。
采用本实施例，用户设备可以根据控制信息指示确定用于发送控制信息的传输子带的频域位置，从而使用户设备可以完成对控制信息的接收。
在高频TDD系统的特殊子帧类型1中，由于每子帧最多只有一个下行控制符号，不再需要使用控制信息指示指示控制信息的时域位置。因此，基站也可以不发送控制 信息指示，而直接按照预定的规则发送控制信息，而用户设备也可以直接按照预定规则确定控制信息的频域位置并接收控制信息。具体的实现方式可以参见如下实施例。
参见图4，为本申请数据发送方法另一个实施例的流程示意图。如图4所示，所述方法可以包括：
步骤401，基站确定待发送的控制信息的份数M，以及每一份控制信息对应的传输子带。
基站首先确定待发送控制信息的份数M，M的取值可以由基站在每次发送控制信息时，根据控制信息的传输需求在预先设定的范围内选定，从而使所述基站可以在每次发送控制信息时，根据需要发送不同份数的控制信息。M的取值的确定方式可以参见前述实施例中N的取值的确定方式，在此就不再赘述。
在M的取值确定之后，基站根据与该取值对应的确定规则，确定每一份控制信息所占用的传输子带，其中，每一个传输子带可以包含相同数量的基本子带，也可以包含不同数量的基本子带。
例如，当所述M的取值范围被预先设定为1至4其中之一时。基站可以根据控制信息的传输需求，选择1、2、3或4中任意一个作为M的取值。当M的取值为3时，基站可以按照预先设定的划分规则，将系统带宽划分为3个传输子带，其中，所述3个传输子带的带宽可以相等也可以不相等。
步骤402，基站在每个所述传输子带发送对应的控制信息。
在控制信息的份数及每一份控制信息对应的传输子带确定之后，基站可以使用所述传输子带传送所述传输子带对应的控制信息。
当所述基站及所述用户设备均为长期演进(long term evolution，简称：LTE)系统中的设备时，基站可以通过控制信息的公共搜索空间传输该指示信息，所述指示信息用于指示控制信息的份数及每一份控制信息所对应传输子带的信息，从而使用户设备可以通过该指示信息确定控制信息的份数及每一个传输子带的子带信息。即，在每一个传输子带所传输控制信息的公共搜索空间中，都携带有指示信息，该指示信息用于指示控制信息的份数，及每一份控制信息所对应传输子带的子带信息。
例如，通信系统可以在PDCCH CSS中新定义一种专用于控制信息传输的资源指示的指示信息，如该指示信息可以为特定加扰的，如以N-RNTI(new radio network temporary indentity)加扰的一种控制信息，该指示信息专门用于指示控制信息的份数 及每一个传输子带的信息。基站可以每子帧发送该指示信息，从而使用户设备可以在每个子帧通过盲检PDCCH CSS中携带的所述指示信息来确定控制信息的份数及每一份控制信息所对应传输子带的子带信息。
采用本实施例，可以使用户设备可以通过对控制信道进行检测确定用于传输控制信息的频域资源位置，从而可以不再使用专门的时间单元发送控制信息指示。
参见图5，为本申请数据接收方法另一个实施例的流程示意图。如图5所示，所述方法可以包括：
步骤501，用户设备通过对控制信息的公共搜索空间进行检测确定对应的控制信息的份数M以及每一份控制信息对应的传输子带。
根据M的取值的确定方式不同，用户设备确定对应的控制信息的份数M以及每一份控制信息对应的传输子带的方式也可以各不相同。
当控制信息的份数由基站在预先设定的范围内选定时，所述用户设备在可用于传输所述控制信息的传输子带中盲检获得所述M份控制信息。所述控制信息的份数的最大数量T可以为预设值。在控制信息传输之前，用户设备可以首先确定T的取值及系统带宽，在T的取值及系统带宽确定后，可能传输控制信息的传输子带的数量及每一个传输子带的子带信息随之也可以确定，从而使用户设备通过盲检确定控制信息的频域位置，并完成控制信息的接收。
为指示控制信息的份数及每一份控制信息所对应传输子带的信息，基站可以通过控制信息的公共搜索空间传输指示信息，所述指示信息用于指示控制信息的份数及每一份控制信息所对应传输子带的信息。因此，用户设备可以通过盲检公共搜索空间中的所述系统信息来确定传输子带的数量及每一个传输子带所对应的信息。
当PDCCH CSS中包含专用于控制信息传输资源指示的指示信息时，用户设备可以根据该指示信息确定M的取值，及每一个传输子带的信息。例如，当所述指示信息以N-RNTI加扰时，用户设备可以通过盲检确定PDCCH CSS中以N-RNTI加扰的指示信息。如果检测到以N-RNTI加扰的指示信息，基站可以通过所述指示信息的内容确定M的取值及每一个传输子带的信息。
步骤502，所述用户设备通过所述传输子带接收对应的控制信息。
在传输子带的数量及每一个传输子带的信息确定之后，所述用户设备可以通过所述传输子带接收相应的控制信息。
采用本实施例，用户设备可以通过对控制信息的公共搜索空间进行盲检确定每一份控制信息的传输子带，并完成控制信息的接收，从而可以使基站不再使用专门的时间单元发送控制信息指示。
