Description

一种信息传输方法、装置和系统 技术领域

背景技术
随着无线网络技术的发展，层出不穷的业务对无线资源的需求日益增加。为了适应某些网络，如小覆盖网络，中所需的上下行业务特性的快速变化，动态时分双工(D-TDD，Dynamic Time Division Duplex)技术越来越受到关注。所谓D-TDD，就是指根据网络内上下行业务负载情况，灵活快速地切换时分双工(Time Division Duplex，TDD)子帧或时隙的上下行，从而匹配网络中具体业务需求，提高网络上下行业务的吞吐量。
第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)中在Rel-12阶段已经初步完成了对D-TDD的标准化工作(标准中的相关部分是增强型干扰管理和传输自适应eIMTA，Enhanced Interference Management and Traffic Adaptation)。3GPP目前已展开第5代网络(5th Generation，5G)新空口(New Radio，NR)标准的制定，D-TDD是NR的重要特性之一。

为了更好地获得D-TDD技术灵活高效的性能优势，有效地提升D-TDD的性能增益，可以通过测量参考信号(MRS，Measurement Reference Signal)来对D-TDD中存在的干扰进行检测。如何提供一种适用于未来网络，如5G场景下的测量参考信号成为一个亟需解决的问题。

第三代合作伙伴计划(英文：3rd generation partnership project，简称3GPP)是一个致力于发展无线通信网络的项目。通常，将3GPP相关的机构称为3GPP机构。
无线通信网络，是一种提供无线通信功能的网络。无线通信网络可以采用不同的通信技术，例如码分多址(英文：code division multiple access,简称CDMA)、宽带码分多址(wideband code division multiple access，简称WCDMA)、时分多址(英文：time division multiple access，简称：TDMA)、频分多址(英文：frequency division multiple access,简称FDMA)、正交频分多址(英文：orthogonal frequency-division multiple access,简称：OFDMA)、单载波频分多址(英文：single Carrier FDMA，简称：SC-FDMA)、载波侦听多路访问/冲突避免(英文：Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或未来演进网络，如5G网络。典型的2G网络包括全球移动通信系统(英文：global system for mobile communications/general packet radio service，简称：GSM)网络或者通用分组无线业务(英文：general packet radio  service，简称：GPRS)网络，典型的3G网络包括通用移动通信系统(英文：universal mobile telecommunications system，简称：UMTS)网络，典型的4G网络包括长期演进(英文：long term evolution,简称：LTE)网络，未来演进网络，如5G网络，可以采用新无线(new radio，NR)技术。其中，UMTS网络有时也可以称为通用陆地无线接入网(英文：universal terrestrial radio access network，简称：UTRAN)，LTE网络有时也可以称为演进型通用陆地无线接入网(英文：evolved universal terrestrial radio access network，简称：E-UTRAN)。根据资源分配方式的不同，可以分为蜂窝通信网络和无线局域网络(英文：wireless local area networks，简称：WLAN)，其中，蜂窝通信网络为调度主导，WLAN为竞争主导。前述的2G、3G和4G网络，均为蜂窝通信网络。本领域技术人员应知，随着技术的发展本发明实施例提供的技术方案同样可以应用于其他的无线通信网络，例如4.5G或者5G网络，或其他非蜂窝通信网络。为了简洁，本发明实施例有时会将无线通信网络简称为网络。
蜂窝通信网络是无线通信网络的一种，其采用蜂窝无线组网方式，在终端设备和网络设备之间通过无线通道连接起来，进而实现用户在活动中可相互通信。其主要特征是终端的移动性，并具有越区切换和跨本地网自动漫游功能。
用户设备(英文：user equipment，简称：UE)是一种终端设备，可以是可移动的终端设备，也可以是不可移动的终端设备。该设备主要用于接收或者发送业务数据。用户设备可分布于网络中，在不同的网络中用户设备有不同的名称，例如：终端，移动台，用户单元，站台，蜂窝电话，个人数字助理，无线调制解调器，无线通信设备，手持设备，膝上型电脑，无绳电话，无线本地环路台等。该用户设备可以经无线接入网(radio access network，简称：RAN)(无线通信网络的接入部分)与一个或多个核心网进行通信，例如与无线接入网交换语音和/或数据。
基站(英文：base station，简称：BS)设备，也可称为基站，是一种部署在无线接入网用以提供无线通信功能的装置。例如在2G网络中提供基站功能的设备包括基地无线收发站(英文：base transceiver station,简称：BTS)和基站控制器(英文：base station controller,简称：BSC)，3G网络中提供基站功能的设备包括节点B(英文简称：NodeB)和无线网络控制器(英文：radio network controller,简称：RNC)，在4G网络中提供基站功能的设备包括演进的节点B(英文：evolved NodeB，简称：eNB)，在5G网络中提供基站功能的设备包括继续演进的节点B(gNB)，在WLAN中，提供基站功能的设备为接入点(英文：access point，简称：AP)。

接入点(英文：access point，简称：AP)，连接无线网络，亦可以连接有线网络的设备。它能当作中介点，使得有线与无线上网的设备互相连接、传输数据。
RRC(radio resource control)：无线资源控制
RRC处理UE和UTRAN之间控制平面的第三层信息。通常包含以下功能中的至少一项：
广播核心网非接入层提供的信息。RRC负责网络系统信息向UE的广播。系统信息通常情况下按照一定的基本规律重复，RRC负责执行计划、分割和重复。也支持上层信息的广播。
将广播信息关联到接入层。RRC负责网络系统信息向UE的广播。系统信息通常情况下按照一定的基本规律重复，RRC负责执行计划、分割和重复。
建立、重新建立、维持和释放在UE和UTRAN之间的RRC连接。为了建立UE的第一个信号连接，由UE的高层请求建立一个RRC的连接。RRC连接建立过程包括可用小区的重新选择、接入许可控制以及2层信号链路的建立几个步骤。RRC连接释放也是由高层请求，用于拆除最后的信号连接；或者当RRC链路失败的时候由RRC本层发起。如果连接失败，UE会要求重新建立RRC连接。如果RRC连接失败，RRC释放已经分配的资源。
时域资源单位：
用于描述无线通信系统中时域资源调度和/或分配的单位，可以对应于LTE系统中的子帧，或，时隙。一个时域资源单位可以由多于一个符号资源构成，多于一个时域资源单位可以构成一个时间更长的时域资源，比如对应LTE系统中的帧。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如本申请所使用的，术语“组件”、“模块”、“系统”等等旨在指代计算机相关实体，该计算机相关实体可以是硬件、固件、硬件和软件的结合、软件或者运行中的软件。例如，组件可以是，但不限于是：在处理器上运行的处理、处理器、对象、可执行文件、执行中的线程、程序和/或计算机。作为示例，在计算设备上运行的应用和该计算设备都可以是组件。一个或多个组件可以存在于执行中的过程和/或线程中，并且组件可以位于一个计算机中以及/或者分布在两个或更多个计算机之间。此外，这些组件能够从在其上具有各种数据结构的各种计算机可读介质中执行。这些组件可以通过诸如根据具有一个或多个数据分组(例如，来自一个组件的数据，该组件与本地系统、分布式系统中的另一个组件进行交互和/或以信号的方式通过诸如互联网之类的网络与其它系统进行交互)的信号，以本地和/或远程过程的方式进行通信。
此外，本申请结合无线设备来描述各个方面，其中，无线设备可以为无线网络设备，也可以为终端设备。该无线网络设备可以为基站，基站可以用于与一个或多个用户设备进行通信，也可以用于与一个或多个具有部分用户设备功能的基站进行通信(比如宏基站与微基站，如接入点，之间的通信)；该无线设备还可以为用户设备，用户设备可以用于一个或多个用户设备进行通信(比如D2D通信)，也可以用于与一个或多个基站进行通信。用户设备还可以称为用户终端，并且可以包括系统、用户单元、用户站、移动站、移动无线终端、移动设备、节点、设备、远程站、远程终端、终端、无线通信设备、无线通信装置或用户代理的功能中的一些或者所有功能。用户设备可以是蜂窝电话、无绳电话、会话发起协议(SIP)电话、智能电话、无线本地环路(WLL)站、个人数字助理(PDA)、膝上型计算机、手持式通信设备、手持式计算设备、卫星无线设备、无线调制解调器卡和/或用于在无线系统上进行通信的其它处理设备。基站还可以称为接入点、节点、节点B、演进节点B(eNB)、继续演进节点B(gNB)或某种其它网络实体，并且可以包括以上网络实体的功能中的一些或所有功能。基站可以通过空中接口与无线终端进行通信。该通信可以通过一个或多个扇区来进行。基站可以通过将所接收的空中接口帧转换成IP分组，来用作无线终端和接入网络的其余部分之间的路由器，其中所述接入网络包括互联网协议(IP)网络。基站还可以对空中接口特征的管理进行协调，并且还可以是有线网络和无线网络之间的网关。举例而言，基站可以为演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)、无线保真(Wireless Fidelity，WIFI)、接入点(Access Point，AP)，传输点(transmission and receiver point，TRP或者transmission point，TP)等，还可以为5G，如NR(new radio)，系统中的gNB，或，传输点(TRP(transmitting and receiving point)或TP(transmission point))，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，数据单元(DU，data unit)等。在一些部署中，gNB可以包括控制单元(CU，control unit)和DU。gNB还可以包括射频单元(RU，radio unit)。CU实现gNB的部分功能，DU实现gNB的部分功能， 比如，CU实现RRC(无线资源控制，radio resource control)，PDCP(packet data convergence protocol，分组数据汇聚层协议)层的功能，DU实现RLC(radio link control,无线链路控制)、MAC(media access control,媒体接入控制)和PHY(physical)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。
本申请将围绕可包括多个设备、组件、模块等的系统来呈现各个方面、实施例或特征。应当理解和明白的是，各个系统可以包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。

本发明实施例以无线通信网络中4G网络的场景为例进行说明，应当指出的是，本发明实施例中的方案还可以应用于其他无线通信网络中，如5G通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
需指出的是，本发明实施例中的方法或装置可以应用于基站和用户设备之间，也可以应用于基站和基站(如宏基站和微基站)之间，还可以应用于用户设备和用户设备(如D2D场景)之间，在本发明部分实施例中，以基站和UE之间的通信为例进行描述。
图1-1所示为一种通信系统的结构示意图。通信系统可以包括核心网，接入网和终端。在图1-1中仅示出了接入网所包括的无线网络设备，如基站，和终端，如用户设备。
图1-2所示为基站和UE的内部结构的简化示意图。
示例的，基站可以包括天线阵列，双工器，发信机(TX)和收信机(RX)(有时，TX和RX统称为收发信机TRX)，以及基带处理部分。其中，双工器用于实现天线阵列既用于发送信号，又用于接收信号。TX用于实现射频信号和基带信号之间的转换，通常TX可以包括功率放大器PA，数模转换器DAC和变频器，通常RX可以包括低噪放LNA，模数转换器ADC和变频器。基带处理部分用于实现所发送或接收的信号的处理，比如层映射、预编码、调制/解调，编码/译码等，并且对于物理控制信道、物理数据信道、物理广播信道、参考信号等进行分别的处理。
在一个示例中，基站还可以包括控制部分，用于进行多用户调度和资源分配、导频调度、用户物理层参数配置等。
示例的，UE可以包括天线，双工器，发信机(TX)和收信机(RX)(有时，TX和RX统称为收发信机TRX)，以及基带处理部分。在图1-2中，UE具有单天线。可以理解的是，UE也可以具有多天线(即天线阵列)。
其中，双工器用于实现天线阵列既用于发送信号，又用于接收信号。TX用于实现射频信号和基带信号之间的转换，通常TX可以包括功率放大器PA，数模转换器DAC和变频器，通常RX可以包括低噪放LNA，模数转换器ADC和变频器。基带处理部分用于实现所发送或接收的信号的处理，比如层映射、预编码、调制/解调，编码/译码等，并且对于物理控制信道、物理数据信道、物理广播信道、参考信号等进行分别的处理。
在一个示例中，UE也可以包括控制部分，用于请求上行物理资源、计算下行信道对应的信道状态信息(CSI)、判断下行数据包是否接收成功等等。
5G系统仍为OFDM系统(采用了OFDM技术的系统)，OFDM系统的子载波间隔选择取决于频谱效率和抗频偏能力的折中。在一定循环前缀(CP，Cyclic Prefix)长度下，子载波间隔越小，OFDM符号周期越长，系统频谱效率越高。但同时，过小的子载波间隔对多普勒频移和相位噪声过于敏感，会影响系统性能。相反，子载波间隔越大，OFDM符号周期越短，但可以提高对抗多普勒频移和相位噪声的能力，同时降低傅里叶变换(FFT)变换的复杂度。
NR技术支持多种子载波间隔(如15KHz、30KHz、60KHz等)的OFDM符号通过频分复用(FDM，Frequency Division Multiplexing)和/或时分复用(TDM，Time Diviosn Multiplexing)的方式复用，如图2所示。

这样，可以第一UE对接收到的第一测量参考信号进行测量，并可以利用测量结果对上行数据传输进行控制，比如调整上行数据传输的控制，以降低UE间的干扰。
可选的，所述测量参考信号的子载波间隔可以为预先定义的，无需无线网络设备特定的配置来指示(如显式指示)。这样可以减少配置的开销。

下面以一种具体的时域资源单位的结构为例，对上述如图3或如4的实施例进行具体描述。
在一种可选的方案中，提出了一种演进型子帧或时隙结构(如图11所示)，这种子帧或时隙结构包括下行控制区域和上行数据区域，或者，下行控制区域和下行数据区域，并且，在下行控制区域与上行数据区域之间插入GP，以及相同的子帧或时隙上，在下行控制区域与下行数据区域之间插入GP，并将GP中的部分区域用于进行基站间和/或UE间的干扰的测量。
本申请的发明人在研究的过程中发现，GP中插入的测量参考信号也需要考虑上下行转换的间隔，那么如果在GP中插入的测量参考信号采用与数据信道相同的子载波间隔，原本仅用于上下行转换而设置的GP的时间长度则需拉长，才能容纳用于传输测量参考信号的部分，并保证测量参考信号在基站和/或UE处接收的准确性。比如如果测量参考信号时域上占用1个符号，而为保证测量参考信号在基站和/或UE处接收的准确性，需额外空出1个符号用作发送定时调整，这样的话，会使得一个子帧或时隙中能用来传输数据信道的符号数减少。
有鉴于此，本申请提供应用于上述结构的参考信号的传输方法，既可以支持基站间和/或UE间的干扰的测量，又可以减少用于干扰测量的资源的开销。

该方法还可以包括：
S502，无线网络设备基于所述时域资源单位的结构进行通信。
其中，传输包括发送或接收。
上行是指UE发送，无线网络设备接收的方向，下行是指UE接收，无线网络设备发送的方向。
其中，所述第二部分还用于上下行切换(含上行至下行的切换，或，下行至上行的切换)所需的保护间隔。
一种可能的情况为：
时域资源单位为一个子帧或时隙，也可以为其他时域资源上的单位。时域资源单位的结构包括时域资源单位的第一结构和时域资源单位的第一结构，其中，第一结构包括用于控制信号接收的第一部分和用于下行数据接收的第三部分，在所述第一部分和第三部分中间有用于参考信号发送的第二部分；第二结构包括用于控制信号接收的第一部分和用于上行数据发送的第三部分，在所述第一部分和第三部分中间有用于参考信号接收的第二部分。

这样，一方面可以通过利用上下行切换的保护间隔这个时间区域进行UE之间的干扰的测量，另一方面，由于用于干扰测量的参考信号的子载波间隔比数据传输的子载波间隔大，因此参考信号的OFDM符号周期小于数据的OFDM符号周期，可以在保证参考信号的收发在时域上对齐的同时减少时域资源的开销，从而减少了参考信号对数据信道的影响，充分利用了时域资源。此外，由于子载波间隔越大，FFT变换的处理越简单，因为，本方案也进一步简化了UE侧对参考信号的处理，减少了UE的处理的开销。

可选的，上述参考信号(第一参考信号，和/或，第二参考信号)的子载波间隔可以是显式指示的，比如，第一参考信号(用于UE间干扰测量)通过动态或半静态信令进行配置，其中，动态信令可以承载在控制信道上，比如通过承载在控制信道上的下行控制信息(downlink control information，DCI)进行指示，半静态信令可以承载在高层信令(如无线资源控制(radio resource control，RRC)信令)或广播信道中。第二参考信号(用于无线网络设备间干扰测量)通过无线网络设备间的交互来指示，在交互中采用显式指示。
可选的，上述参考信号(第一参考信号，和/或，第二参考信号)的子载波间隔可以是隐式指示的，比如，可以采用与某一信道的子载波间隔相同或与某一信道的子载波间隔具有固定关系，所述某一信道可以包括同步信号或广播信道。其中，所述某一信道的子载波间隔可以为预先定义的，也可以为显式或隐式指示的。所述固定关系可以为预先定义的，也可以为显式或隐式指示的。

如图6b所示，本申请实施例还提供一种信息传输的方法，对应的时域资源单位的结构示意图如6a所示，该方法包括：
S601，无线网络设备基于时域资源单位的结构进行通信，所述时域资源单位的结构包括用于控制信号传输的第一部分和用于上行或下行数据传输的第三部分，在所述第一部分和第三部分中间有用于参考信号传输的第二部分，其中，所述参考信号的子载波间隔为所述上行或下行数据的子载波间隔的倍数。其中，控制信号可以包括下行控制信号。

其中，所述第二部分还用于上下行切换(含上行至下行的切换，或，下行至上行的切换)所需的保护间隔。
一种可能的情况为：
时域资源单位为一个子帧或时隙，也可以为其他时域资源上的单位。时域资源单位的结构包括时域资源单位的第一结构和时域资源单位的第一结构，其中，第一结构包括用于控制信号发送的第一部分和用于下行数据发送的第三部分，在所述第一部分和第三部分中间有用于参考信号接收的第二部分；第二结构包括用于控制信号发送的第一部分和用于上行数据接收的第三部分，在所述第一部分和第三部分中间有用于参考信号发送的第二部分。

具体的，无线网络设备可以包括第一无线网络设备和第二无线网络设备，上述方法中S601可以包括：
S6011，第一无线网络设备基于时域资源单位的第一结构进行通信,包括：第一无线网络设备在第一部分发送控制信号，在第二部分接收参考信号，在第三部分发送下行数据；和/或
S6012，第二无线网络设备基于时域资源单位的第二结构进行通信，包括：第二无线网络设备在第一部分发送控制信号，在第二部分发送参考信号，在第三部分接收上行数据。
这样，第一无线网络设备在第一部分接收参考信号，如测量参考信号，从而可以获知第二无线网络设备对第一无线网络设备的干扰，并且可以根据信道互异性，获知第一无线网络设备的第三部分上下行数据的发送对第二无线网络设备的第三部分上上行数据的接收的干扰。
上述方法中S602可以包括：
S6021，第一UE在第一部分接收来自第一无线网络设备的控制信号，在第三部分接收来自第一无线网络设备的下行数据；和/或，
S6022，第二UE在第一部分接收来自第二无线网络设备的控制信号，在第三部分向第二无线网络设备发送上行数据。
这样，一方面可以通过利用上下行切换的保护间隔这个时间区域进行无线网络设备之间的干扰的测量，另一方面，由于用于干扰测量的参考信号的子载波间隔比数据传输的子载波间隔大，因此参考信号的OFDM符号周期小于数据的OFDM符号周期，可以在保证参考信号的收发在时域上对齐的同时减少时域资源的开销，从而减少了参考信号对数据信道的影响，充分利用了时域资源。此外，由于子载波间隔越大，FFT变换的处理越简单，因为，本方案也进一步简化了无线网络设备侧对参考信号的处理，减少了无线网络设备的处理的开销。
可选的，上述S601中的参考信号为第二参考信号，用于无线网络设备间的干扰的测量，上述S6021还可以包括：
第一UE在第二部分发送第一参考信号；
上述S6022还可以包括：
第二UE在第二部分接收第一参考信号。
其中，第一参考信号用于UE间的干扰的测量。
第一参考信号和第二参考信号的序列不同。
第一参考信号的子载波间隔为数据的子载波间隔的倍数。
这样，还可以同时利用第二部分进行UE间的干扰测量，进一步提高了时域资源的利用率。
可选的，上述参考信号(第一参考信号，和/或，第二参考信号)的子载波间隔可以是预先定义的，如由系统或标准协议预先定义好，这样，无线网络设备和UE就可以依据预先定义的子载波间隔进行参考信号的传输。
可选的，上述参考信号(第一参考信号，和/或，第二参考信号)的子载波间隔可以是显式指示的，比如，第一参考信号(用于UE间干扰测量)通过动态或半静态信令进行配置，其中，动态信令可以承载在控制信道上，比如通过承载在控制信道上的下行控制信息(downlink control information，DCI)进行指示，半静态信令可以承载在高层信令(如无线资源控制(radio resource control，RRC)信令)或广播信道中。第二参考信号(用于无线网络设备间干扰测量)通过无线网络设备间的交互来指示，在交互中采用显式指示。
可选的，上述参考信号(第一参考信号，和/或，第二参考信号)的子载波间隔可以是隐式指示的，比如，可以采用与某一信道的子载波间隔相同或与某一信道的子载波间隔具有固定关系，所述某一信道可以包括同步信号或广播信道。其中，所述某一信道的子载波间隔可以为预先定义的，也可以为显式或隐式指示的。所述固定关系可以为预先定义的，也可以为显式或隐式指示的。

可选的，所述确定可以为上述预先定义，也可以为上述显式或隐式指示的，所述指示可以通过第一无线网络设备与第二无线网络设备之间的交互来实现。
可选的，上述方法还可以包括：
S6002，无线网络设备向所述UE配置所述第一参考信号的子载波间隔。
可选的，所述配置可以为上述显式配置或隐式配置。
通过上述实施例，一方面可以保证无线网络设备和/或UE间的干扰测量，另一方面可以 减少用于测量的参考信号传输以及所述参考信号的保护间隔所带来的开销，进而可以提高时域资源的利用率，保证数据传输的效率。
通过上述实施例的参考信号的传输，可以实现根据本时域资源单位的干扰测量的结果进行短时调控，如进行本时域资源单位的功率控制，速率调整等，也可以根据多个时域资源单位的干扰测量结果进行长时调控，比如根据测量结果进行用户调度或资源分配等。
根据多个时域资源单位的干扰测量结果进行长时调控的场景中，由于动态TDD下不同邻区所使用的上述时域资源单位的结构可以是所述第一结构也可以是所述第二结构(即可以是不同的)，且一个小区的邻区可能有一个或多个，那么不同时域资源单位上，一个小区的UE所受到的邻小区的UE的干扰也可能是不同的。比如如图7所示，为一个小区有2个邻区的情况，该小区称为第一小区，邻区包括第二小区和第三小区。第一小区的UE为第一UE，第二小区的UE为第二UE，第三小区的UE为第三UE。为了表述方便，前述第一结构可以简称为下行(UL)结构，第二结构可以简称为上行(UL)结构。可以看到，图7中所示的5个时域资源单位上，第一UE的UL结构中的第二部分所接收到的第二UE和第三UE的参考信号是有变化的，比如，第一UE的第一个UL结构中，第一UE可以测到来自邻区的两个UE(第二UE和第三UE)的测量参考信号(因为第二UE和第三UE也是UL结构)；第一UE的第二个UL结构中，第一UE测不到来自邻区的测量参考信号(因为第二UE和第三UE也都为UL结构)，第一UE的第三个UL结构中，第一UE可以测到来自一个邻区的UE(第二UE)的测量参考信号(因为第三UE为UL结构，第二UE为DL结构)。所以第一UE的不同时域资源单位的UL结构，其测到的干扰量不相同。
此外，第一UE还可以在UL结构中接收来自无线网络设备侧的参考信号(并不限于前述时域资源单位的结构，这里的UL结构也可以是其他时域资源单位的结构下的UL结构，参考信号也可以不是UL结构中第二部分承载的参考信号，比如来自无线网络设备侧的参考信号占用的是下行控制传输部分，比如所述参考信号为下行参考信号)，对下行链路进行测量，此时，第一UE的UL结构所测得的参考信号，可以来自服务第一UE的第一无线网络设备和/或邻区所属的无线网络设备(如服务第二UE的第二无线网络设备和服务第三UE的第三无线网络设备)，由于在邻区相同的时域资源单位上，如果为DL结构，则邻区所属的无线网络设备所下发的参考信号也可以由第一UE的下行控制传输部分进行接收，这样，在相同的时域资源单位上，第一UE不但可以测到第一无线网络设备下发的参考信号，还可以测到邻区中DL结构的无线网络设备下发的参考信号，从而可以测量到邻区对本小区(第一UE所在小区)的干扰。这样，由于不同的小区的时域资源单位的结构是可变的，第一UE测到的下行链路的干扰也是可变的。
有鉴于此，本发明实施例还提出了一种信息的传输方法，如图8所示，包括：
S801，第一无线网络设备向第一UE发送时域资源单位的特征信息。其中，所述特征信息与时域资源单位上受到的干扰相关，或者，与时域资源单位上的数据传输方向相关。其中，时域资源单位上的数据传输方向可以包括第一UE(或第一UE所在小区)以及第一小区所在小区的邻区在时域资源单位上的数据传输方向的信息。
可选的，S801之前包括第一无线网络设备确定第一UE(或第一UE所属第一小区)的一个时域资源单位的特征信息；
其中，一个时域资源单位的特征信息可以用于指示第一小区的时域资源单位的结构以及与第一小区相邻的小区(也可简称为邻区)的时域资源单位的结构的信息。
其中，第一小区相邻的小区属于第二无线网络设备，或者，属于第一无线网络设备。
可选的，所述时域资源单位为用于第一UE的上行数据传输的时域资源单位。
可选的，可以将上述第一UE(或者第一UE所在小区)的时域资源单位上数据传输的方向以及与第一小区的邻区的时域资源单位上数据传输的方向的信息(简称为时域资源单位集合的方向信息)进行编码。可选的，针对第一小区的用于上行数据传输的时域资源单位而言，可以按照邻区的时域资源单位上用于下行数据传输的时域资源单位的个数进行编码，比如，个数为0时，将所述时域资源单位集合的方向信息编为第一信息，比如为0，个数为1时，将所述时域资源单位集合的方向信息编为第二信息，比如为1，个数为2时，将所述时域资源单位集合的方向信息编为第三信息，比如为2，以此类推。相应的，所述时域资源单位的特征信息可以根据所述时域资源单位集合的方向信息确定，不同的时域资源单位集合的方向信息对应不同的时域资源单位的特征信息。一种可选的方式为，时域资源单位的特征信息等于所述时域资源单位集合的方向信息。可以理解的是，时域资源单位的特征信息的编码方式可以为系统预先定义的，这样第一无线网络设备和第一UE之间可以根据时域资源单位的特征信息确定时域资源单位集合的方向信息，从而确定所测得的干扰信息所属的类别(也称为干扰级别)。其中干扰信息所属的类别可以对应于时域资源单位集合的方向信息，当邻区的时域资源单位的方向与本小区的时域资源单位的方向不同时，则可以视作干扰，而依据干扰有无，或者干扰个数的不同，可以确定不同的干扰信息所属的类别。比如，干扰个数为0，干扰信息所属的类别为第一类，干扰个数为1，干扰信息所属的类别为第二类，干扰个数为2，干扰信息所属的类别为第三类，以此类推。可选的，可以将本小区和邻区的时域资源单位上的数据传输方向进行编码，比如，0表示数据传输方向为上行，1表示数据传输方向为下行，用每1比特(bit)表示相应的小区，如以三个小区为例，最高位表示本小区，其他位依次表示邻区(可以按照邻区id进行排序或按照其他规则，该规则在整个系统中可以为预定义的，不需空口配置)，000，表示一个时域资源单位上的三个小区的数据传输方向均为上行，010，表示一个时域资源单位上的本小区的数据传输方向为上行，邻区中一个为下行，另一个为上行，001，表示一个时域资源单位上的本小区的数据传输方向为上行，邻区中一个为上行，另一个为下行，011，表示一个时域资源单位上的本小区的数据传输方向为上行，两个邻区均为下行。这种方式下，可选的，由于010和001，UE受到的干扰的个数均为1个，即干扰信息的类别相同，UE可以将010和001这两个编码对应的测量结果采用相同的处理方式，并将测量结果进行合并后上报。
可选的，无线网络设备确定第一UE(或第一UE所属第一小区)的一个时域资源单位的特征信息可以具体包括：
无线网络设备与第一小区的邻区所属的无线网络设备之间进行交互各自的时域资源单位的结构，从而使得无线网络设备获知第一UE所属第一小区以及第一小区的邻区的时域资源单位的结构，进而确定第一UE所属第一小区的一个时域资源单位的特征信息。
可选的，S801中一个时域资源单位的特征信息可以通过动态或半静态信令进行发送。
其中，动态信令可以承载在控制信道中，如下行控制信道上的下行控制信息(DCI)中。
半静态信令可以承载在广播信道或高层信令，如无线资源控制(RRC)信令中。
当一个时域资源单位上的数据传输方向是通过动态信令进行配置的，则该时域资源单位的特征信息可以通过动态信令进行配置；或者，
当一个时域资源单位上的数据传输方向是通过半静态信令进行配置的，则该时域资源单 位的特征信息可以通过半静态信令进行配置。
可以理解的是，虽然本实施例针对第一UE进行的描述，但第一UE并非特指的UE，针对第二UE和第三UE，服务第二UE的无线网络设备也可以执行图8所对应的方法，服务第三UE的无线网络设备也可以执行图8所对应的方法。
可选的，S801还可以包括：
第一UE接收来自第一无线网络设备的所述时域资源单位的特征信息。
所述方法还可以包括
S803，第一UE根据所述时域资源单位的特征信息对时域资源单位上获得的测量结果进行处理。
S804，第一UE向第一无线网络设备上报测量结果。
可选的，S803可以包括：第一UE根据至少两个时域资源单位的特征信息对至少两个时域资源单位上的测量结果进行处理；一种可能的方式为：将特征信息相同的时域资源单位上的测量结果进行合并处理。另一种可能的方式为：根据特征信息所对应的干扰信息的类别将多个时域资源单位上的测量结果进行合并处理；其中，特征信息和干扰信息的类别之间的对应关系可以为预定义的。
可选的，所述合并处理可以为：将具有同一干扰信息的类别的时域资源单位的测量结果进行平均或是加权处理(如平滑滤波)，并将平均或加权处理后的结果发给无线网络设备。这样，无线网络设备就可以根据所接收的结果较准确的获知信道状态。具体的，无线网络设备获知所上报的测量结果对应的干扰级别，可以通过所上报的测量结果的特定的时频资源(不同级别对应不同时频资源)，或所上报的测量结果的特定的编码(不同级别对应不同编码)，或所上报的测量结果为根据无线网络设备相应的指示进行的上报，或者，不同干扰级别对应的测量结果的序号不同，等各种方式中一种进行获知，在此不予限定。
