Description

无线通信方法和设备 技术领域
本发明实施例涉及无线通信领域，并且更具体地，涉及一种无线通信方法和设备。
背景技术
长期演进(Long Term Evolution，LTE)的时分双工(Time Division Duplexing，TDD)系统通常具有7种上下行子帧配比，如表1所示。
表1 TDD系统的上下行子帧配比
Figure PCTCN2016077807-appb-000001
在表1中，每个子帧的持续时间为1ms，D表示下行子帧，U表示上行子帧，S表示特殊子帧。
图1为特殊子帧的示意性结构图。在图1中，子帧1为特殊子帧，特殊子帧包括下行导频时隙(Downlink Pilot Time Slot，DwPTS)、GP和上行导频时隙(Uplink Pilot Time Slot，UpPTS)。DwPTS可以传输下行数据。GP是保护间隔，用于下行到上行的切换。UpPTS一般包括1到2个上行符号(symbol)，可以用来传输上行探测参考信号(Sounding Reference Signal，SRS)或上行控制信道。
由上文可以看出，现有TDD系统中的子帧内部结构固定，在一个子帧内传输的信息类型有限，使得通信系统的信息传输方式受限，可能无法满足后续通信系统(如5G)的要求。

具体实施方式
应理解，本发明实施例可以应用于各种通信系统，例如：GSM(全球移动通讯，Global System of Mobile communication)系统、CDMA(码分多址，Code Division Multiple Access)系统、WCDMA(宽带码分多址，Wideband Code Division Multiple Access)系统、GPRS(通用分组无线业务，General Packet Radio Service)、LTE(长期演进，Long Term Evolution)系统、LTE-A(先进的长期演进，Advanced long term evolution)系统、UMTS(通用移动通信系统，Universal Mobile Telecommunication System)、5G等，下文仅是以5G的需求为例。
5G系统主要部署在高频段，这样小区的覆盖范围与4G和3G系统相比会大大缩小。当小区范围变小时，每小区的用户数也会对应变小，这样小区的数据流量的变化可能也会比较快。为了更好的适应小区数据流量的快速变化，5G系统的TDD要有快速而灵活配置上下行信道资源的能力。对TDD系统来说，可以通过在7种TDD配置中切换来适应上下行数据流量的变化。由于目前TDD的配置是以帧(frame)为单位定义的，目前系统中最快的切换速度也就是10ms,可能并不能满足5G系统流量动态变化的需求。
可以通过定义更多的TDD配置来更精确的实现上下行流量的配比，但是这样又带来更复杂的确认信号的时序设计问题。目前LTE系统中的传输确认信号(ACK/NACK)是采取固定的时间顺序的：对于某一种特定的配置而言， 对于某个子帧上的确认信号会在其后一个预先设定的子帧上传输。假设系统中有N种TDD配置，按照现有LTE系统时序设计原则，需要考虑N*N种不同的时序关系。这对未来的5G系统设计是一个制约。
因此，亟需提出一种新的子帧结构，能够比现有7种配置更灵活的适应上下行数据流量的变化。
图2是本发明实施例的子帧结构示意图。从图2可以看出，无线通信系统中的子帧包括下行优先子帧、上行优先子帧和双向子帧中的至少一种；其中，下行优先子帧沿时域方向依次包括下行控制信道、下行信道、保护间隔和上行控制信道；上行优先子帧沿时域方向依次包括下行控制信道、保护间隔、上行信道和上行控制信道；双向子帧帧沿时域方向依次包括下行控制信道、保护间隔、上行信道、下行信道、保护间隔和上行控制信道；其中，下行控制信道用于传输下行控制信息，上行控制信道用于传输上行控制信息，下行信道用于传输下行数据和/或下行控制信息，上行信道用于传输上行数据和/或上行控制信息。
应理解，子帧包括信道是指子帧包括信道对应的时域资源或时频资源。
本发明实施例中的子帧结构能够比现有7种配置更灵活的适应上下行数据流量的变化。
在一些实施例中，沿时域方向可以指沿时域递增的方向；在一些实施例中，沿时域方向可以也指沿时域递减的方向。
在一些实施例中，无线通信系统中的子帧的最前段可以是固定的下行控制信道，用于传输下行控制信息。在一些实施例中，下行控制信道还可以用于传输子帧的类型信息，终端接收到该下行控制信道之后，可以根据子帧的类型信息判断该子帧是下行优先子帧、上行优先子帧、双向子帧中的哪一种。
在一些实施例中，无线通信系统中的子帧的最后段是固定的上行控制信道，用于传输上行控制信息。在一些实施例中，该上行控制信息例如可以是调度请求(Scheduling Request，SR)，信道质量指示(Channel Quality Indicator，CQI)，A/N信息(即ACK/NACK信息)，探测参考信号(Sounding Reference Signal，SRS)和随机接入信道(Primary Random Channel，PRCH)等。
在以上实施例中，由于每个子帧都配有下行和上行控制信道，使得重要的下行和上行控制信息能及时的在每个子帧内得到传输。
在一些实施例中，双向子帧的上下行信道的比例信息(上下行信道在时 间宽度上的比例)可以由基站配置。在一些实施例中，此比例信息可以在子帧前段的下行控制信道里传输。
上文结合表1和图1介绍了现有的LTE的TDD系统的子帧结构，如果5G系统中的TDD也采取上述帧结构配置，会产生较严重的延时问题。具体地，由于目前TDD帧结构中，多数子帧要么是上行子帧，要么是下行子帧。而上/下行数据传输，需要在其他下/上行子帧(对应关系预先确定)中传递ACK/NACK信息。当由于TDD结构的限制，无法及时的传输ACK/NACK信号时，延时就产生了。这种延时是由于LTE中TDD帧结构设置本身产生的。5G系统中对延时提出了较高的要求，希望在无线接入层的延时能缩小到1ms(1个子帧)以下。如果还沿用目前的LTE系统对TDD的帧结构的配置，很难保证5G系统的延时要求。为了解决由于TDD配置带来的延时问题，本发明实施例在引入上行优先子帧、下行优先子帧、双向子帧的基础上，进一步引入这些子帧中的上/下行数据的ACK/NACK反馈时序。
在一个实施例中，下行优先子帧的上行控制信道用于传输下行优先子帧的下行信道中的下行数据的ACK/NACK信息，参见图3。
本发明实施例提供了简单的A/N信号传输时序，能够缩短TDD系统的由于传输A/N信号产生的延时。
在一个实施例中，上行优先子帧的下行控制信道用于传输上行优先子帧的前一子帧中的上行数据的ACK/NACK信息，参见图4。
本发明实施例提供了简单的A/N信号传输时序，能够缩短TDD系统的由于传输A/N信号产生的延时。
在一个实施例中，双向子帧的下行信道用于传输双向子帧的上行信道中的上行数据的ACK/NACK信息，参见图5。
本发明实施例提供了简单的A/N信号传输时序，能够缩短TDD系统的由于传输A/N信号产生的延时。
在一个实施例中，双向子帧的上行控制信道用于传输双向子帧的下行信道中的下行数据的ACK/NACK信息，参见图5。
本发明实施例提供了简单的A/N信号传输时序，能够缩短TDD系统的由于传输A/N信号产生的延时。
在上述三种类型的子帧的基础上，可以引入三种过渡子帧：下行过渡子帧、上行过渡子帧和双向过渡子帧。
参见图6，下行过渡子帧沿时域方向依次包括下行控制信道、保护间隔、下行信道、保护间隔、上行控制信道；上行过渡子帧沿时域方向依次包括下行控制信道、保护间隔、上行信道、保护间隔和上行控制信道；双向过渡子帧沿时域方向依次包括下行控制信道、保护间隔和上行控制信道。
在一些实施例中，过渡子帧的类型可以在子帧最开始的下行控制信道中指示。
下面介绍如何结合上文中的三种基本类型的子帧和过渡类型的子帧，实现更加灵活的系统频谱配置。
在一些实施例中，无线通信系统包括第一下行优先子帧和第一双向子帧，其中，在时域方向，第一下行优先子帧与第一双向子帧的时域位置相同；在频域方向，第一下行优先子帧与第一双向子帧之间设置有下行过渡子帧，且下行过渡子帧的保护间隔将第一双向子帧的上行信道与第一下行优先子帧的下行信道相隔，参见图7。
具体地，当下行优先子帧和双向子帧要在同一时间(子帧内)部署时，两种子帧在频率域上可以插入下行过渡子帧，利用下行过渡子帧中的保护时隙来隔离下行优先子帧中的下行信道和双向子帧中的上行信道，避免二者在相邻频率域发生冲突。
在一些实施例中，无线通信系统包括第一上行优先子帧和第二双向子帧，其中，在时域方向，第一上行优先子帧与第二双向子帧的时域位置相同；在频域方向，第一上行优先子帧与第二双向子帧之间设置有上行过渡子帧，且上行过渡子帧的保护间隔将第二双向子帧的下行信道与第一上行优先子帧的上行信道相隔，参见图8。
具体地，当上行优先子帧和双向子帧要在同一时间(子帧内)部署时，两种子帧在频率域上可以插入上行过渡子帧，利用上行过渡子帧中的保护时隙来隔离上行优先子帧中的上行信道和双向子帧中的下行信道，避免二者在相邻频率域发生冲突。
在一些实施例中，无线通信系统包括第二上行优先子帧和第二下行优先子帧，其中，在时域方向，第二上行优先子帧与第二下行优先子帧的时域位置相同；在频域方向，第二上行优先子帧与第二下行优先子帧之间设置有双向过渡子帧，且双向过渡子帧的保护间隔将第二上行优先子帧的上行信道与第二下行优先子帧的下行信道相隔，参见图9。
具体地，当上行优先子帧和下行优先子帧要在同一时间(子帧内)部署时，两种子帧在频率域上可以插入双向过渡子帧，利用双向过渡子帧中的保护时隙来隔离上行优先子帧中的上行信道和下行优先子帧子帧中的下行信道，避免二者在相邻频率域发生冲突。
通过引入3种过渡子帧，使得3种基本子帧结构能在频率上更灵活的组合。
