以长期演进-时分双工(Long Term Evolution-TDD,TDD LTE)系统为例,上下行传输占用不同的子帧,以避免收发通道间的干扰。TDD LTE系统中,一个无线帧中包括10个子帧,按照子帧被配置为上行子帧、下行子帧或特殊子帧
当网络设备支持全双工时,可以在一个子帧上,向一个终端设备进行下行发送的同时接收另一个终端设备的上行发送,即对于一个终端设备,该子帧为下行子帧,而对于另一个终端设备,该子帧为上行子帧,这里,将这样的子帧称为“全双工子帧”。
若终端设备不知道一个无线帧中的哪些子帧是全双工子帧,则可能无法规避其他终端设备在不同的传输方向上可能带来的强干扰。

下面,对本发明实施例涉及得到的相同的描述进行解释。需要说明的是,这些解释是为了让本发明实施例更容易被理解,而不应该视为对本发明实施例所要求的保护范围的限定。
1、全双工
在目前已商用的无线通信系统中,受限于通信设备(比如:网络设备或终端设备)的干扰处理能力,要求一个通信设备在同一无线资源(比如:LTE系统中的时频资源)上不能同时发送和接收,否则发送的信号和接收的信号之间会产生严重干扰,极大降低通信质量。
以目前LTE系统的两种制式为例:采用FDD双工方式的FDD LTE系统中,如图1所示,在同一时刻,同一通信设备分别在不同的频点接收和发送;而采用TDD双工方式的TDD LTE系统中,如图2所示,在同一频点,同一通信设备分别在不同的时刻接收和发送。
随着通信设备,特别是网络设备,比如:基站对干扰处理能力的大幅度提升,一些网络设备能够支持在同一频点、同一时刻上进行发送和接收,我们这种双工方式称为“全双工”方式。
采用全双工方式,相比于在同一频点、同一时刻仅支持发送或接收的双工方式,频谱效率将提升一倍。
本发明实施例中,网络设备支持全双工,即网络设备可以在同一时间、同一频点同时接收和发送。
具体到一个无线帧的各个子帧,若一个网络设备可以在一个子帧同时进行下行发送和上行接收,则这样的子帧为“全双工子帧”;
一个无线帧中除了全双工子帧之外的子帧之外的其他子帧为普通子帧。
2、帧格式配置
帧格式配置是指一个无线帧中包括的各种不同的子帧在无线帧中的位置。
比如:若子帧分为上行子帧、下行子帧,则帧格式配置表示一个无线帧中,各个上行子帧和各个下行子帧在该无线帧中的位置。
再比如:若子帧分为上行子帧、下行子帧和特殊子帧,则帧格式配置表示一个无线帧中,各个上行子帧、各个下行子帧和特殊子帧在该无线帧中的位置。
再比如:对于终端设备可进行设备到设备(Device to Device,D2D)通信的情景,子帧类型还可包括用于进行D2D传输的子帧。
为了更形象地描述帧格式配置,以目前TDD LTE系统为例,一个无线帧可具有多种帧格式配置,称为上行-下行配比(Uplink-downlink configuration)。目前,TDD LTE的协议已经定义了表1所列的7种帧格式配置,其中,“D”代表下行子帧,“S”代表特殊子帧,以及“U”代表上行子帧。
表1、TDD LTE帧格式配置
本发明实施例中,将子帧分为普通子帧和全双工子帧,如前所述,全双工子帧为网络设备可以同时进行下行发送和上行接收的子帧,一个无线帧中除了全双工子帧之外的子帧之外的其他子帧为普通子帧。
仍以TDD LTE系统为例,若网络设备为小区内的一部分终端设备配置了上行-下行配比0,而为另一部分终端设备配置了上行-下行配比1,则子帧4、子帧9为全双工子帧,其他子帧为普通子帧。在子帧4,配置了上行-下行配比0的终端设备进行上行发送,配置了上行-下行配比1的终端设备进行下行接收,而对应同时服务于具有不同上行-下行配比的终端设备的网络设备,则实现了同时收发,从而实现了全双工。
再比如:若网络设备为小区内的一部分终端设备配置了上行-下行配比5,而为另一部分终端设备配置了上行-下行配比6,则子帧3、4、6、7、8为全双工子帧,其他子帧为普通子帧。其中,对于上行-下行配比6,子帧6是特殊子帧,按照目前TDD LTE协议的定义,特殊子帧中包括上行导频时隙(Uplink Pilot Time Slot,UpPTS)、下行导频时隙(Downlink Pilot Time Slot,DwPTS)和保护间隔(Guard Period,GP),而因此网络设备可以在子帧6的UpPTS进行上行接收,同时,按照上行-下行配比5,网络设备又可以同时在子帧6进行下行发送,因此子帧6也是全双工子帧。
3、系统和网络
术语“系统”和“网络”在本发明实施例中常被可互换使用。本发明实施例中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
以上介绍了本发明实施例涉及的相同的描述,下面结合附图对本发明实施例进行详细说明。
图3示出了本发明实施例提供的无线通信系统的结构示意图。如图3所示,该无线通信系统包括:网络设备301和终端设备302,在网络设备301管辖的一个小区覆盖范围内,可存在一个或多个终端设备302,若存在多个终端设备302,这多个终端设备302使用的帧格式配置可不同。
比如:如图3所示,在网络设备301管辖的一个小区的覆盖范围内,有三个终端设备302,其中两个采用帧格式配置1,另一个采用帧格式配置2。这和以往的无线通信系统中的帧格式配置方式不同,以往的无线通信系统中,在一个小区内,所有的终端设备均采用相同的帧格式配置,不会出现本发明实施例中的一个小区内的不同终端设备302采用不同的帧格式配置的情况。
一个小区内的不同终端设备采用不同的帧格式配置,实现上更灵活,也可提供整个小区的传输资源的利用率。
由于一个小区内的不同终端设备采用不同的帧格式配置,则可能出现在一些子帧中,
网络设备301同时进行下行发送和上行接收的情形,则这些子帧为全双工子帧。
图3所示的无线通信系统的通信制式包括但不限于:全球移动通信系统(Global System of Mobile communication,GSM)、码分多址(Code Division Multiple Access,CDMA)IS-95、码分多址(Code Division Multiple Access,CDMA)2000、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access,TD-SCDMA)、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)、时分双工-长期演进(Time Division Duplexing-Long Term Evolution,TDD LTE)、频分双工-长期演进(Frequency Division Duplexing-Long Term Evolution,FDD LTE)、长期演进-增强(Long Term Evolution-Advanced,LTE-advanced)、个人手持电话系统(Personal Handy-phone System,PHS)、802.11系列协议规定的无线保真(Wireless Fidelity,WiFi)、全球微波互联接入(Worldwide Interoperability for Microwave Access,WiMAX),以及未来演进的各种无线通信系统。
其中,终端设备302可以是无线终端,无线终端可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(例如,RAN,Radio Access Network)与一个或多个核心网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(PCS,Personal Communication Service)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL,Wireless Local Loop)站、个人数字助理(PDA,Personal Digital Assistant)等设备。无线终端也可以称为订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户设备(User Equipment)。
网络设备301可包括基站,或用于控制基站的无线资源管理设备,或包括基站和用于控制基站的无线资源管理设备;其中基站可为宏站或小站,比如:小小区(small cell)、微小区(pico cell)等,基站也可为家庭基站,比如:家庭节点B(Home NodeB,HNB)、家庭演进节点B(Home eNodeB,HeNB)等,基站也可包括中继节点(relay)等。
比如:对于TDD LTE、FDD LTE或LTE-A等LTE系统,本发明实施例提供的无线通信系统中的网络设备101可为演进节点B(evolved NodeB,eNodeB),终端设备302可为UE;对于TD-SCDMA系统或WCDMA系统,本发明实施例提供的无线通信系统中的网络设备301可包括:节点B(NodeB)和/或无线网络控制器(Radio Network Controller,RNC),终端设备302可为UE;对于GSM系统,本发明实施例提供的中的网络设备101可包括基站收发台(Base Transceiver Station,BTS)和/或基站控制器(Base Station Controller,BSC),终端设备302为移动台(Mobile Station,MS);对于WiFi系统,网络设备301可包括:接入点(Access Point,AP)和/或接入控制器(Access Controller,AC),终端设备302可为站点(STAtion,STA)。
图4示出了网络设备301和终端设备302交互的流程图。如图4所示,该流程包括如下步骤:
S401:网络设备301确定帧格式配置的第一配置信息,并向终端设备302发送该确定的第一配置信息;
S402:终端设备302在收到第一配置信息后,确定全双工子帧和普通子帧在一个无线帧中的位置;
S403:终端设备302根据确定的全双工子帧和普通子帧在一个无线帧中的位置,分别针对全双工子帧和普通子帧进行无线测量;
S404:网络设备301向终端设备302发送针对终端设备302的专用的帧格式配置的第二配置信息;

下面,对图4所示的流程加以详细说明。
S401:网络设备301确定帧格式配置的第一配置信息,并向终端设备302发送该确定的第一配置信息。
其中,第一配置信息的实现可有多种方式,只要能够实现终端设备302根据该第一配置信息确定全双工子帧和普通子帧在一个无线帧中的位置即可。
下面,列举两种可能的实现方式:
方式一、

比如:网络设备301在生成第一指示信息时,可采用bitmap的方式。
假设一个无线帧中包括10个子帧。可通过下面表2所示的位图(bitmap)生成第一指示信息。其中,1表示对应的子帧为全双工子帧,0表示对应的子帧为普通子帧。
表2、第一指示信息bitmap
0 | 0 | 0 | 1 | 1 | 0 | 0 | 1 | 1 | 1 |
其中,网络设备301可通过广播消息或专用信令向终端设备302发送第一指示信息。
比如:网络设备301可将第一指示信息置于系统消息块(System Information Block,SIB)中发给一个小区内的所有终端设备。
再比如:网络设备301可向终端设备302发送专用信令,比如:无线资源控制(Radio Resource Control,RRC)消息,在该专用信令中通过字段RRC子帧分配(RRCSubframeAssignment)携带该第一指示信息,该字段的长度可为10bit,即一个无线帧中的子帧的数量。
方式二、
第一配置信息包括多个第二指示信息,其中每一个第二指示信息用于指示一个小区内可使用的一种帧格式配置。
其中,网络设备301也可通过广播消息或专用信令发送这多个第二指示信息。
比如:网络设备301将多个第二指示信息置于SIB中发给终端设备302。第二指示信息可通过字段SIB子帧分配(SIBSubframeAssignment)携带,多个第二指示信息分别通过下述字段携带:
SIBSubframeAssignment0;
SIBSubframeAssignment1;
SIBSubframeAssignment2;
……
SIBSubframeAssignmentM-1;
M为大于1的正整数,表示多个第二指示信息的个数。
比如:以TDD LTE系统为例,M=2,SIBSubframeAssignment0为上行-下行配比0;SIBSubframeAssignment1为上行-下行配比1,则子帧4和子帧9为全双工子帧,其余子帧为普通子帧。
S402:终端设备302在收到第一配置信息后,确定全双工子帧和普通子帧在一个无线帧中的位置。
下面分别以上述方式一和方式二为例,说明终端设备302确定全双工子帧和普通子帧在一个无线帧中的位置的可选方案。
方式一、
终端设备302可确定bitmap中,取值为1的bit为全双工子帧所在位置,取值为0的bit为普通子帧所在的位置。
方式二
方式二中,终端设备302在确定全双工子帧和普通子帧的位置时可采用如下可选方式之一:
可选方式一、
若在一个无线帧中的同一位置处,多个第二指示信息所指示的帧格式配置中,按照部分帧格式配置,该同一位置处为上行子帧;按照其他帧格式配置,该同一位置处为下行子帧,则终端设备302确定在该同一位置处的子帧为全双工子帧;
可选方式二、
若在一个无线帧中的同一位置处,多个第二指示信息所指示的帧格式配置中,按照部分帧格式配置,该同一位置处为上行子帧;按照其他帧格式配置,该同一位置处为特殊子帧,则终端设备302确定在该同一位置处的子帧为全双工子帧;
可选方式三、
若在一个无线帧中的同一位置处,多个第二指示信息所指示的帧格式配置中,按照部分帧格式配置,该同一位置处为下行子帧;按照其他帧格式配置,该同一位置处为特殊子帧,则终端设备302确定在该同一位置处的子帧为全双工子帧。
比如:N=2,多个第二指示信息为上述的SIBSubframeAssignment0和SIBSubframeAssignment1,SIBSubframeAssignment0为上行-下行配比0;SIBSubframeAssignment1为上行-下行配比1,则终端设备302按照SIBSubframeAssignment0,确定子帧4为上行子帧,按照SIBSubframeAssignment1确定子帧4为下行子帧,则终端设备302确定子帧4为全双工子帧;同理,终端设备302也能够确定子帧9为全双工子帧。则除了全双工子帧之外的其他子帧为普通子帧。
S403:终端设备302根据确定的全双工子帧和普通子帧在一个无线帧中的位置,分别针对全双工子帧和普通子帧进行无线测量。
对于全双工子帧,由于部分终端设备在全双工子帧进行上行发送,而另一些终端设备在全双工子帧进行下行接收,相对于在同一时刻仅进行上行发送或下行接收的普通子帧而
言,干扰水平并不相同。
参考图5,在网络设备301覆盖下的一个小区中,在一个全双工子帧中,一个终端设备302进行上行发送,另一个终端设备302进行下行接收,则进行上行发送的终端设备302会对进行下行接收的终端设备302产生干扰,我们将这种干扰称为“小区内上下行干扰(Uplink-Downlink Inteference,UDI)”。
而对于普通子帧,则不存在UDI。
因此,全双工子帧和普通子帧的干扰水平不同,终端设备302在获知一个无线帧中的全双工子帧和普通子帧的位置后,可针对全双工子帧和普通子帧分别独立地进行无线测量,分别得到两种子帧的干扰水平值,以达到最佳的链路自适应效果。
S404:网络设备301向终端设备302发送针对终端设备302的专用的帧格式配置的第二配置信息;
其中,步骤S404与步骤S401之间的顺序并不限定,步骤S404可在步骤S401之前完成,或在步骤S401之后完成,再或者两个步骤同时完成,比如:第一配置信息和第二配置信息在同一个消息中下发。
网络设备301在发送第二配置信息时的一种可选的实现方式是:
当终端设备302接入小区后,网络设备301可通过专用信令,比如前述的RRC信令,将第二配置信息发给终端设备302。
仍以TDD LTE系统为例,参考前面的表1,网络设备301可通过RRC信令向终端设备302指示上行-下行配比,比如:将表1中的上行-下行配比0配置给一个终端设备302,向该终端设备302发送用于指示上行-下行配比0的第二配置信息;将表1中的上行-下行配比1配置给另一个终端设备302,向该终端设备302发送用于指示上行-下行配比1的第二配置信息。
S405:终端设备302根据收到的第二配置信息,确定自身使用的帧格式配置。
终端设备302接收网络设备301发送的专用的帧格式配置的第二配置信息,根据该第二配置信息,确定自身使用的专用的帧格式配置。
比如:以TDD LTE系统为例,终端设备302可以按照协议规定的表1,根据收到的第二配置信息,确定自身使用哪种上行-下行配比。
S406:终端设备302根据确定的自身使用的帧格式配置,确定自身使用的HARQ定时配置。
终端设备302可根据协议中规定的上行-下行配比对应的HARQ定时配置,确定自身使用的上行-下行配比所对应的HARQ定时配置。
S407:终端设备302根据确定的自身使用的HARQ定时配置,进行上下行传输。
