Description

传输控制方法、装置及系统 存储介质
本申请要求于2016年11月3日提交中国专利局、申请号为201610959460.6、发明名称为“传输控制方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，特别涉及一种传输控制方法、装置及系统 存储介质。
背景技术
先进长期演进(英文：Long term evolution-advanced；简称：LTE-A)系统包括用户设备(英文：User equipment；简称：UE)和为UE服务的基站，在通信的过程中，基站可以向UE下发下行控制信息(英文：Downlink Control Information；简称：DCI)来对UE进行调度。
相关技术中，DCI携带在基站发往UE的子帧里，且DCI通常由物理下行控制信道(英文：Physical Downlink Control Channel；简称：PDCCH)承载。在时域上，PDCCH占用子帧最前端的若干个正交频分复用(英文：Orthogonal Frequency-Division Multiplexing；简称：OFDM)符号，且PDCCH占用的OFDM符号的数量由物理控制格式指示信道(英文：Physical Control Format Indicator Channel；简称：PCFICH)承载的控制格式指示(英文：Control Format Indicator；简称：CFI)信息指示；在频域上，PDCCH占用子帧内的全部子载波，其中，PDCCH占用子帧内的全部子载波也即是PDCCH占用整个系统带宽内的全部子载波(即宽带)。UE通过对PDCCH中承载的DCI进行盲检测，来对基站发给自身的DCI进行接收。

此处的附图被并入说明书中并构成本说明书的一部分，示出了符合本申请的实施例，并与说明书一起用于解释本申请的原理。
具体实施方式
在LTE-A系统中，PCFICH用于承载CFI信息，该CFI信息用于指示PDCCH在时域内所占用的OFDM符号的数量，PCFICH承载的CFI信息所代表的比特图(英文：bitpattern)用于表示不同的OFDM的数量。而在LTE-A系统中，PDCCH在频域内所占用的带宽是宽带(英文：wideband)的，也即是PDCCH在频域内所占用的带宽是系统带宽，所以无需指 示PDCCH在频域内是否是子带(英文：subband)以及subband的具体位置。
在第五代(英文：Fifth Generation；简称：5G)系统中，需要为PDCCH设置不同的承载时频资源。需要说明的是，本申请中涉及到了下行控制信道、控制格式指示信道和下行共享信道，为便于描述，本申请将以PDCCH来指代下行控制信道，以PCFICH来指代控制格式指示信道，以物理下行共享信道(Physical Downlink Shared Channel；简称：PDSCH)来指代下行共享信道为例进行说明。然而，本领域的技术人员应当明白，在本申请提供的技术方案中，下行控制信道可以与现有通信标准中的PDCCH相同，也可以在现有PDCCH所具备的功能基础之上包含其他的功能，或者仅具备现有PDCCH中的一部分功能，也可以在这一部分功能的基础上包含现有PDCCH不具备的其他功能。控制格式指示信道可以与现有通信标准中的PCFICH相同，也可以在现有PCFICH所具备的功能基础之上包含其他的功能，或者仅具备现有PCFICH中的一部分功能，也可以在这一部分功能的基础上包含现有PCFICH不具备的其他功能。下行共享信道可以与现有通信标准中的PDSCH相同，也可以在现有PDSCH所具备的功能基础之上包含其他的功能，或者仅具备现有PDSCH中的一部分功能，也可以在这一部分功能的基础上包含现有PDSCH不具备的其他功能。本申请对此不作限定。
请参考图1，其示出了本申请实施例所涉及一种实施环境的示意图，该实施环境提供一种无线通信系统。该实施环境可以包括：发送端设备01和接收端设备02，发送端设备01可以为接入网设备，接收端设备02可以为用户设备。
其中，接入网设备例如但不限于：全球移动通信(英文：Global System for Mobile Communication；简称：GSM)系统中的基站(英文：Base Transceiver Station；简称：BTS)，宽带码分多址(英文：Wideband Code Division MultipleAccess；简称：WCDMA)系统中的NB(英文：NodeB)，长期演进(英文：Long Term Evolution；简称：LTE)系统中的演进型基站(英文：evolvedNode B；简称：eNB)、中继站、车载设备、可穿戴设备以及未来5G系统中的接入网设备或者未来演进的公共陆地移动网络(英文：Public Land Mobile Network；简称：PLMN)网络中的接入网设备。
在本实施环境以及下述各个实施例中，用户设备将以一般意义上的UE来介绍。此外，用户设备也可以为移动台、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。用户设备可以是蜂窝电话、无绳电话、会话启动协议(英文：Session Initiation Protocol；简称：SIP)电话、无线本地环路(英文：Wireless Local Loop；简称：WLL)站、个人数字处理(英文：Personal DigitalAssistant；简称：PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及未来5G网络中的移动台或者未来演进的PLMN网络中的终端设备等。此外，用户设备还可以包括中继(英文：Relay)等其他能够和接入网设备(例如，基站)进行通信的设备。
在本实施环境以及下述各个实施例中，发送端设备01与接收端设备02建立有通信连接，并可以通过该通信连接进行通信，在无线通信系统中，该通信连接通常为无线连接，发送端设备01与接收端设备02在通信时传输的信息可以包括但不限于：控制格式指示信息、控制信息、数据信息等，控制格式指示信息如LTE中的CFI信息等，控制信息如LTE中的DCI等，发送端设备01与接收端设备02可以通过信道传输信息，信道可以承载在时 频资源上，示例地，发送端设备01与接收端设备02可以通过下行控制信道传输下行控制信息，下行控制信道可以承载在传输单元中的时频资源上，发送端设备01可以将下行控制信息映射到下行控制信道在传输单元中所占用的时频资源上，并通过该时频资源来向接收端设备02发送下行控制信息，接收端设备02可以通过对下行控制信道在传输单元中所占用的时频资源上的下行控制信息进行盲检测，来实现对发送端设备01发送给自身的下行控制信息的接收。其中，传输单元可以如图2所示。
请参考图2，其示出了本申请实施例提供的一种传输单元200的逻辑结构示意图，该传输单元200相当于现有LTE系统中的物理资源块(英文：Physical Resource Block；简称：PRB)、PRB pair(PRB对)或者子帧。参见图2，该传输单元200包括时域上的N个符号(英文：Symbols)和频域上的M个子载波(英文：Subcarrier)，其中，符号可以为OFDM符号，M与N均为正整数，且M与N的具体取值可以根据需要设置，比如，在LTE中，N的取值可以等于12或14。传输单元200包括两个TTI，每个TTI相当于LTE系统中的一个时隙，每个TTI包括N/2个符号，且传输单元200中的最小资源单位为资源粒(英文：Resource Element；简称：RE)，每个资源粒包括时域上的一个符号和频域上的一个子载波。
需要说明的是，为便于描述，图2所示的传输单元200采用了LTE系统中子帧的结构，但是，本领域的技术人员应当明白，传输单元200也可采用其他的结构，例如，可以根据具体的需要设置传输单元200中时频资源的数量、传输单元200中所包含的符号的数量以及传输单元200中所包含的子载波的数量等等。还需要说明的是，本申请实施例中的符号还可以采用其他命名方式，例如时间单元，本申请实施例中的子载波还可以采用其他命名方式，例如频率单元，本申请实施例中的传输单元200还可以采用其他命名方式，例如资源单元，本申请实施例对此不作限定。
相关技术中，基站(例如图1中的发送端设备01)可以通过子帧向UE(例如图1中的接收端设备02)下发DCI，该DCI承载在PDCCH上，该PDCCH位于子帧中，且PDCCH在子帧中所占的带宽是宽带的，UE通过在子帧中对PDCCH进行盲检测，来对下行控制信息进行接收。但是由于PDCCH在子帧中所占的带宽是宽带的，导致PDCCH占用的时频资源相对固定，无法根据需要调整PDCCH占用的时频资源。
请参考图3，其示出了本申请实施例提供的一种传输控制方法的方法流程图，该传输控制方法可以应用于图1所示实施环境，用于发送端设备01与接收端设备02之间传输下行控制信息，本实施例以发送端设备01为基站，接收端设备02为UE为例进行说明。参见图3，该传输控制方法包括：

步骤303、接收端设备接收发送端设备发送的目标控制格式指示信息。
发送端设备向接收端设备发送目标控制格式指示信息时，接收端设备可以接收发送端设备发送的目标控制格式指示信息，其中，目标控制格式指示信息用于指示下行控制信道所占用的目标时频资源。具体地，接收端设备可以接收目标传输单元，然后在目标传输单元中的控制格式指示信道上获取目标控制格式指示信息。其中，控制格式指示信道在目标传输单元中所占用的时频资源是发送端设备与接收端设备预先约定好的，接收端设备可以接收目标传输单元，然后根据与发送端设备的约定在目标传输单元中确定控制格式指示信道，并从控制格式指示信道获取目标控制格式指示信息，本申请实施例在此不再赘述。其中，发送端设备与接收端设备约定控制格式指示信道在目标传输单元中所占用的时频资源，可以保证下行控制信息的有效接收。
步骤304、接收端设备根据目标控制格式指示信息确定目标时频资源。
接收端设备接收发送端设备发送的目标控制格式指示信息后，可以根据目标控制格式指示信息确定目标时频资源，其中，由于目标控制格式指示信息指示的是目标时频资源，因此，接收端设备获取目标控制格式指示信息后，可以直接根据目标控制格式指示信息确定目标时频资源，其中，该目标时频资源指的是目标传输单元中的时频资源，该目标传输单元可以是目标控制格式指示信息所在的时频资源。
需要说明的是，本申请实施例是以发送端设备将目标控制格式指示信息映射在目标传输单元中，通过目标传输单元向接收端设备发送目标控制格式指示信息为例进行说明的，实际应用中，发送端设备向接收端设备发送的目标传输单元中可能不包括目标控制格式指示信息，比如，发送端设备向接收端设备发送图6所示的目标传输单元，在图6所示的目标传输单元中，下行控制信道可以承载在子带1中的f个子载波上，并且承载在该传输单元的前N/2个符号上，但是图6所示的目标传输单元中不包括控制格式指示信道，也不包括目标控制格式指示信息，此时接收端设备无法确定图6所示的目标传输单元中的目标时频资源。在本申请实施例中，为了避免这种情况的发生，当接收端设备接收到的目标传输单元中不包括目标控制格式指示信息时，接收端设备可以将距离目标传输单元最近的传输单元中的控制格式指示信息确定为目标控制格式指示信息，并根据目标控制格式指示信息确定目标传输单元中的确定目标时频资源，可选地，接收端设备可以将距离目标传输单元最近且位于目标传输单元之前的包括控制格式指示信息的传输单元中的控制格式指示信息确定为目标控制格式指示信息，比如，目标传输单元可以如图6所示，距离目标传输单元最近且位于目标传输单元之前的包括控制格式指示信息的传输单元可以如图5所示，因此，接收端设备可以将图5所示的传输单元中的控制格式指示信息确定为目标控制格式指示信息，并根据此控制格式指示信息确定目标时频资源，本申请实施例在此不再赘述。
步骤305、接收端设备根据目标时频资源确定下行控制信道。
接收端设备确定目标时频资源后，可以根据目标时频资源确定下行控制信道，具体地，接收端设备将目标时频资源确定为下行控制信道中的时频资源。
在本申请实施例中，接收端设备确定下行控制信道后，可以根据下行控制信道接收下行控制信息。可选地，接收端设备可以通过对下行控制信道中的下行控制信息进行盲检测，来实现对发送端发送给自身的下行控制信息的接收。其中，下行控制信息可以采用接收端设备的标识加扰，接收端设备可以根据自身的标识对下行控制信道中的下行控制信息进行盲检测，来实现对发送端发送给自身的下行控制信息的接收，其中，此处的标识例如但不限于LTE中的无线网络临时标识(英文：Radio Network Temporary Identity；简称：RNTI)。具体地，接收端设备根据自身的标识依次尝试对下行控制信道中的下行控制信息进行解析，然后进行校验，若校验成功，则盲检测成功，接收端设备便可以确定发送端发送给自身的下行控制信息，其中，接收端设备通过盲检测的方式确定发送端发送给自身的下行控制信息的具体实现过程在相关技术中已清楚描述，因此，其具体实现过程可以参考相关技术，本申请实施例在此不再赘述。
综上所述，本申请实施例提供的传输控制方法，由于目标控制格式指示信息用于指示下行控制信道所占用的目标时频资源，因此，可以根据目标控制格式指示信息灵活调整下行控制信道占用的时频资源，有助于解决无法调整下行控制信道占用的时频资源的问题，灵活调整下行控制信道占用的时频资源。
本申请实施例提供的传输控制方法，由于发送端设备可以对时频资源进行指示，因此，发送端设备可以为不同的接收端设备或者不同群组的接收端设备指示不同的时频资源，使不同接收端设备或不同群组的接收端设备的下行控制信道分布在不同的子带上进行FDM或分布在不同的符号上进行TDM，有助于降低不同接收端设备或不同群组的接收端设备之间的下行控制信息的干扰，提高了下行控制信息接收的可靠性。
本申请实施例提供的传输控制方法，提供了一种新无线技术(英文：New Radio access technology；简称：NR)系统中新的控制格式指示信息，该控制格式指示信息能够动态指示下行控制信道所占用的时频资源，相比LTE的控制格式指示信道，能够更动态地指示下行控制信道所占用的时频资源，使得下行控制信道所占用的时频资源能够动态调整。
