技术领域
本发明实施例涉及信道测量技术，尤其涉及一种信道测量方法。
背景技术
通过信道测量来获得信道状态信息(Channel State Information，CSI)对提升无线通信的传输质量至关重要。在进行信道测量时，接收端设备(例如智能手机等用户设备)根据发射端设备(例如基站等接入设备)发射的参考信号(Reference Signal，RS)获得信道状态信息，并将获得的CSI反馈给发射端设备。发射端设备便基于该CSI对发射信号进行处理并发往接收端设备。由此可见，基于CSI来进行的无线传输与信道环境更加契合，因此传输质量更好。
CSI通常可以通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)，从接收端设备发往发射端设备。通过PUSCH传输的CSI可以包含宽带(Wideband)CSI，也可以包含多个子带(Subband)CSI，还可以既包含宽带CSI也包含多个子带CSI。宽带CSI可以理解为基于宽带计算得到的CSI，子带CSI可以理解为基于子带计算得到的CSI。这里所说的宽带可以是，例如但不限于，整个系统带宽，或者一个射频载波所对应的带宽，也可以是一整块带宽，该一整块带宽包含多个子带，该整块带宽的例子可以是下文将要描述的待测量带宽。宽带可以划分为多个子带，子带的宽度可以根据，例如但不限于，具体的系统设计要求进行设置。当需要反馈的子带CSI较多的时候，会产生很大的开销。

具体实施方式
目前正处于研发阶段的下一代无线通信系统又可称为新无线(New Radio，NR)系统或者5G系统。下一代无线通信标准的最新研究进展表明，CSI可以通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)，从接收端设备发往发射端设备。本领域的技术人员应当明白，相比于主要用于传输控制信息的物理上行控制信道(Physical Uplink Control Channel，PUCCH)，PUSCH主要用于传输数据。因此，在传输CSI时，PUSCH还可以传输数据，也可以不传输数据。例如，一上行子帧(Subframe)中的PUSCH可以既传输CSI也传输数据，也可以仅传输CSI而不传输数据。CSI通常包含在上行控制信息(Uplink Control Information，UCI)中，该UCI通过PUSCH进行传输。UCI可以进一步包含至少两个部分，其中，第一部分所包含的信息比特的数量是固定的，且第一部分用于指示第二部分的信息比特的数量。同时，第一部分的优先级高于第二部分。更进一步的，第一部分和第二部分可以分别独立编码。本领域的技术人员应当明白，最终确定的下一代无线通信标准，也可能发生变化，从而与上述最新研究进展不同。
图1是依照本发明一实施例的频带划分示意图。如图1所示，载波带宽(Carrier Bandwidth)可以视为一种宽带，其进一步包含至少一个带宽部分(Bandwidth Part)。每个带宽部分包含至少一个连续的子带，每个子带进一步包含多个连续的子载波。
每一带宽部分可以对应一组系统参数(numerology)，包括例如但不限于，子载波间隔(Subcarrier spacing)和循环前缀(Cyclic Prefix，CP)等，不同带宽部分可以对应不同的系统参数。可选的，在同一个传输时间间隔(Transmission Time Interval，TTI)内，在多个带宽部分之中，可以仅有一个带宽部分可用，其他带宽部分不可用。
在上报CSI时，可以划分带宽部分的一部分或者全部子带用作CSI上报带宽(CSI  reporting band)，以便上报该CSI上报带宽所对应的CSI。为便于描述，下文将CSI上报带宽简称为上报带宽。不难理解，上报带宽是指一段带宽，且需要上报该带宽对应的CSI，该带宽包含多个子带。上报带宽内承载有发射端设备发出的用于进行信道测量的参考信号，例如但不限于，小区专用参考信号(Cell-specific Reference Signal，CRS)、信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)或者解调参考信号(Demodulation Reference Signal，DMRS)。上述参考信号的相关技术内容属于现有技术，本发明实施例不做限定。接收端设备可以对上述参考信号进行测量，获得对应的CSI。在上报CSI时，可以上报该上报带宽整体的CSI，即上报带宽的宽带CSI，也可以上报该上报带宽内至少一个子带的CSI，还可以结合使用上述两种上报方式，或者采用其他上报方式。如图1所示，上报带宽包含多个连续的子带。然而，在具体实现过程中，上报带宽所包含的子带可以不连续。例如，对于一带宽部分中连续的6个子带，子带1～子带6，上报带宽可以包含子带1～子带2、子带4和子带6。在具体实现过程中，也可以采用其他方式或者层级来对频带进行划分。例如，在不同的划分方式中，子带所包含的子载波的数量可以不同。又例如，在图1所示的频带划分层级之间也可以增加或者删除至少一个层级。本发明实施例对频带划分的具体方式不做限定。
如背景技术部分所述，在进行信道测量时，接收端设备根据发射端设备发射的参考信号(Reference Signal，RS)获得信道状态信息，并将获得的CSI反馈给发射端设备。发射端设备可基于该CSI对发射信号进行处理，并将处理后的发射信号发往接收端设备。在具体实现过程中，CSI可以进一步包括，例如但不限于，下列信息之中的至少一种：信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、CSI-RS资源指示(CSI-RS Resource Indicator，CRI)和秩指示(Rank Indication，RI)。在对发射信号进行处理时，发射端设备可以直接应用接收端设备反馈的CSI进行处理，也可以对接收端设备反馈的CSI进行调整，并使用调整后的CSI进行处理。例如，在具体实现过程中，发射端设备可以降低接收端设备反馈的RI，并使用降低后的RI进行处理。又例如，发射端设备还可以对接收端设备反馈的PMI所对应的预编码矩阵进行重构，并使用重构后的PMI进行处理，其中，该重构过程可以是，例如但不限于，对同时调度的多个接收端设备反馈的PMI所对应的预编码矩阵进行正交化处理。同时调度多个接收端设备进行数据传输的方法也称为多用户多输入多输出(Multi-User Multiple-Input and Multiple-Output(MIMO)，MU-MIMO)技术。再例如，发射端设备还可以降低接收端设备反馈的CQI，并使用降低的CQI进行处理。应注意，若发射端设备对接收端设备反馈的CSI进行调整，则发射端设备有可能需要将调整后的CSI通知接收端设备，以便接收端设备基于调整后的CSI，从接收信号中恢复发射信号。例如，若基站调整RI或者CQI，则基站需要将调整后的RI和CQI通知接收端设备。在具体实现过程中，本发明实施例对发射端设备调整接收端设备反馈的CSI的具体方式不做限定。
如背景技术部分所述，当需要反馈的子带CSI较多的时候，会产生很大的开销。本发明实施例提供了一种技术方案，有助于降低上述开销。下面就结合附图和具体实施例来对本发明实施例提供的技术方案进行详细描述。
图2是依照本发明一实施例的无线通信网络200的示范性示意图。如图2所示，无线通信网络200包括基站202～206和终端设备208～222，其中，基站202～206彼此之间可通 过回程(backhaul)链路(如基站202～206彼此之间的直线所示)进行通信，该回程链路可以是有线回程链路(例如光纤、铜缆)，也可以是无线回程链路(例如微波)。终端设备208～222可通过无线链路(如基站202～206与终端设备208～222之间的折线所示)与对应的基站202～206通信。
基站202～206通常作为接入设备来为通常作为用户设备的终端设备208～222提供无线接入服务。具体来说，每个基站都对应一个服务覆盖区域(又可称为蜂窝，如图2中各椭圆区域所示)，进入该区域的终端设备可通过无线信号与基站通信，以此来接受基站提供的无线接入服务。基站的服务覆盖区域之间可能存在交叠，处于交叠区域内的终端设备可收到来自多个基站的无线信号，因此这些基站可以进行相互协同，以此来为该终端设备提供服务。例如，多个基站可以采用多点协作(Coordinated multipoint，CoMP)技术为处于上述交叠区域的终端设备提供服务。例如，如图2所示，基站202与基站204的服务覆盖区域存在交叠，终端设备222便处于该交叠区域之内，因此终端设备222可以收到来自基站202和基站204的无线信号，基站202和基站204可以进行相互协同，来为终端设备222提供服务。又例如，如图2所示，基站202、基站204和基站206的服务覆盖区域存在一个共同的交叠区域，终端设备220便处于该交叠区域之内，因此终端设备220可以收到来自基站202、204和206的无线信号，基站202、204和206可以进行相互协同，来为终端设备220提供服务。
依赖于所使用的无线通信技术，基站又可称为节点B(NodeB)，演进节点B(evolved NodeB,eNodeB)以及接入点(Access Point，AP)等。此外，根据所提供的服务覆盖区域的大小，基站又可分为用于提供宏蜂窝(Macro cell)的宏基站、用于提供微蜂窝(Pico cell)的微基站和用于提供毫微微蜂窝(Femto cell)的毫微微基站等。随着无线通信技术的不断演进，未来的基站也可以采用其他的名称。
终端设备208～222可以是具备无线通信功能的各种无线通信设备，例如但不限于移动蜂窝电话、无绳电话、个人数字助理(Personal Digital Assistant，PDA)、智能电话、笔记本电脑、平板电脑、无线数据卡、无线调制解调器(Modulator demodulator，Modem)或者可穿戴设备如智能手表等。随着物联网(Internet of Things，IOT)技术的兴起，越来越多之前不具备通信功能的设备，例如但不限于，家用电器、交通工具、工具设备、服务设备和服务设施，开始通过配置无线通信单元来获得无线通信功能，从而可以接入无线通信网络，接受远程控制。此类设备因配置有无线通信单元而具备无线通信功能，因此也属于无线通信设备的范畴。此外，终端设备208～222还可以称为移动台、移动设备、移动终端、无线终端、手持设备、客户端等。
基站202～206，和终端设备208～222均可配置有多根天线，以支持MIMO(多入多出，Multiple Input Multiple Output)技术。进一步的说，基站202～206和终端设备208～222既可以支持单用户MIMO(Single-User MIMO，SU-MIMO)技术，也可以支持多用户MIMO(Multi-User MIMO，MU-MIMO)，其中MU-MIMO可以基于空分多址(Space Division Multiple Access，SDMA)技术来实现。由于配置有多根天线，基站202～206和终端设备208～222还可灵活支持单入单出(Single Input Single Output，SISO)技术、单入多出(Single Input Multiple Output，SIMO)和多入单出(Multiple Input Single Output，MISO)技术，以实现各种分集(例如但不限于发射分集和接收分集)和复用技术，其中分集技术可以包 括例如但不限于发射分集(Transmit Diversity，TD)技术和接收分集(Receive Diversity，RD)技术，复用技术可以是空间复用(Spatial Multiplexing)技术。而且上述各种技术还可以包括多种实现方案，例如发射分集技术可以包括，例如但不限于，空时发射分集(Space-Time Transmit Diversity，STTD)、空频发射分集(Space-Frequency Transmit Diversity，SFTD)、时间切换发射分集(Time Switched Transmit Diversity，TSTD)、频率切换发射分集(Frequency Switch Transmit Diversity，FSTD)、正交发射分集(Orthogonal Transmit Diversity，OTD)、循环延迟分集(Cyclic Delay Diversity，CDD)等分集方式，以及上述各种分集方式经过衍生、演进以及组合后获得的分集方式。例如，目前LTE(长期演进，Long Term Evolution)标准便采用了空时块编码(Space Time Block Coding，STBC)、空频块编码(Space Frequency Block Coding，SFBC)和CDD等发射分集方式。上文以举例的方式对发射分集进行了的概括性的描述。本领域技术人员应当明白，除上述实例外，发射分集还包括其他多种实现方式。因此，上述介绍不应理解为对本发明技术方案的限制，本发明技术方案应理解为适用于各种可能的发射分集方案。
此外，基站202～206和终端设备208～222可采用各种无线通信技术进行通信，例如但不限于，时分多址(Time Division Multiple Access，TDMA)技术、频分多址(Frequency Division Multiple Access，FDMA)技术、码分多址(Code Division Multiple Access，CDMA)技术、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)、正交频分多址(Orthogonal FDMA，OFDMA)技术、单载波频分多址(Single Carrier FDMA，SC-FDMA)技术、空分多址(Space Division Multiple Access，SDMA)技术以及这些技术的演进及衍生技术等。上述无线通信技术作为无线接入技术(Radio Access Technology，RAT)被众多无线通信标准所采纳，从而构建出了在今天广为人们所熟知的各种无线通信系统(或者网络)，包括但不限于全球移动通信系统(Global System for Mobile Communications，GSM)、CDMA2000、宽带CDMA(Wideband CDMA，WCDMA)、由802.22系列标准中定义的WiFi、全球互通微波存取(Worldwide Interoperability for Microwave Access，WiMAX)、长期演进(Long Term Evolution，LTE)、LTE升级版(LTE-Advanced，LTE-A)以及这些无线通信系统的演进系统等。如无特别说明，本发明实施例提供的技术方案可应用于上述各种无线通信技术和无线通信系统。此外，术语“系统”和“网络”可以相互替换。
应注意，图2所示的无线通信网络200仅用于举例，并非用于限制本发明的技术方案。本领域的技术人员应当明白，在具体实现过程中，无线通信网络200还可能包括其他设备，同时也可根据具体需要来配置基站和终端设备的数量。
在具体实现过程中，接入设备如图2所示的基站202～206可用作发射端设备，用户设备如图2所示的终端设备208～222可用作接收端设备。
图3是依照本发明一实施例的通信设备300的示范性逻辑结构示意图。该通信设备300既可以用于实现接收端设备，也可以用于实现发射端设备。如图3所示，通信设备300包含处理模块302和收发模块304，这些模块的具体功能将在下文进行详细的描述。在具体实现过程中，处理模块304可以通过下文将要描述的通信设备400中的处理器402来实现，或者通过通信设备400中的处理器402和存储器408来实现，当然也可以采用其他实现方式。同理，收发模块304可以通过通信设备400中的收发器404来实现，当然也可以 采用其他实现方式。
图4是依照本发明一实施例的通信设备400的示范性硬件结构示意图。该通信设备400既可以用于实现接收端设备，也可以用于实现发射端设备。如图4所示，通信设备400包括处理器402、收发器404、多根天线406，存储器408、I/O(输入/输出，Input/Output)接口410和总线412。存储器408进一步用于存储指令4082和数据4084。此外，处理器402、收发器404、存储器408和I/O接口410通过总线412彼此通信连接，多根天线406与收发器404相连。在具体实现过程中，处理器402、收发器404、存储器408和I/O接口410也可以采用总线412之外的其他连接方式彼此通信连接。
处理器402可以是通用处理器，通用处理器可以是通过读取并执行存储器(例如存储器408)中存储的指令(例如指令4082)来执行特定步骤和/或操作的处理器，通用处理器在执行上述步骤和/或操作的过程中可能用到存储在存储器(例如存储器408)中的数据(例如数据4084)。通用处理器可以是，例如但不限于，中央处理器(Central Processing Unit，CPU)。此外，处理器402也可以是专用处理器，专用处理器可以是专门设计用于执行特定步骤和/或操作的处理器，该专用处理器可以是，例如但不限于，数字信号处理器(Digital Signal Processor，DSP)、应用专用集成电路(Application Specific Integrated Circuit，ASIC)和现场可编程门阵列(Field Programmable Gate Array，FPGA)等。此外，处理器402还可以是多个处理器的组合，例如多核处理器。
收发器404用于收发信号，其具体过程是通过多根天线406之中的至少一根天线来进行的。
存储器408可以是各种类型的存储介质，例如随机存取存储器(Random Access Memory，RAM)、只读存储器(Read Only Memory，ROM)、非易失性RAM(Non-Volatile RAM，NVRAM)、可编程ROM(Programmable ROM，PROM)、可擦除PROM(Erasable PROM，EPROM)、电可擦除PROM(Electrically Erasable PROM，EEPROM)、闪存、光存储器和寄存器等。存储器408具体用于存储指令4082和数据4084，当处理器402为通用处理器时，处理器402可以通过读取并执行存储器408中存储的指令4082，来执行特定步骤和/或操作，在执行上述步骤和/或操作的过程中可能需要用到数据4084。
I/O接口410用于接收来自外围设备的指令和/或数据，以及向外围设备输出指令和/或数据。
在具体实现过程中，处理器可用于进行，例如但不限于，基带相关处理，收发器可用于进行，例如但不限于，射频收发。上述器件可以分别设置在彼此独立的芯片上，也可以至少部分的或者全部的设置在同一块芯片上。例如，处理器可以进一步划分为模拟基带处理器和数字基带处理器，其中模拟基带处理器可以与收发器集成在同一块芯片上，数字基带处理器可以设置在独立的芯片上。随着集成电路技术的不断发展，可以在同一块芯片上集成的器件越来越多，例如，数字基带处理器可以与多种应用处理器(例如但不限于图形处理器，多媒体处理器等)集成在同一块芯片之上。这样的芯片可以称为系统芯片(System on Chip)。将各个器件独立设置在不同的芯片上，还是整合设置在一个或者多个芯片上，往往取决于产品设计的具体需要。本发明实施例对上述器件的具体实现形式不做限定。
应注意，在具体实现过程中，通信设备400还可以包括其他硬件器件，本文不再一一列举。
通信设备400中硬件器件的具体作用将在下文进行详细的描述。
图5是依照本发明一实施例的信道测量方法500的示范性流程图。在具体实现过程中，方法500可由接收端设备来执行，该接收端设备可以由图3所示的通信设备300和图4所示的通信设备400来实现。
步骤502，对于包含至少一个上报子带和至少一个缺失子带的待测量频带，获得每个上报子带的信道状态信息和每个缺失子带的信道状态信息，其中每个上报子带的信道状态信息是基于信道估计得到的，每个缺失子带的信道状态信息是基于参考规则参考所述至少一个上报子带中该参考规则所指示的上报子带的信道状态信息得到的。
在具体实现过程中，步骤502可由处理模块302和处理器402来执行。
步骤504，向发射端设备发送待测量频带的测量报告，其中所述测量报告包含所述至少一个上报子带中每个上报子带的信道状态信息，以便发射端设备为每一缺失子带基于所述参考规则参考所述至少一个上报子带中该参考规则所指示的上报子带的信道状态信息获得该缺失子带的信道状态信息。
在具体实现过程中，步骤504可由收发模块304和收发器404来执行。
相比反馈包含每个子带的信道状态信息的测量报告，本发明实施例反馈的测量报告仅仅包含部分子带的信道状态信息，因此有助于降低信道测量带来的反馈开销。同时，对于其他子带的信道状态信息，接收端设备和发射端设备基于相同的规则根据上述部分子带中该规则所指示的子带的信道状态信息生成上述其他子带中每个子带的信道状态信息，因此有助于在接收端设备和发射端设备之间实现上述信道状态信息的一致性，避免给传输效果带来不利影响。
待测量频带可以包含多个子带，这些子带可以是连续的，也可以是不连续的，还可以是部分连续的，本发明实施例对这些子带是否连续及连续形式不做限定。在具体实现过程中，上述待测量频带可以是上文描述的上报带宽。
待测量频带所包含的多个子带可以划分为两类，分别为上报子带和缺失子带，并且在待测量频带中，上述每一类子带均包含至少一个子带。同时，上报子带的信道状态信息是基于信道估计得到的，而缺失子带的信道状态信息则是基于参考规则参考上报子带中该参考规则所指示的上报子带的信道状态信息得到的。此外，上报子带的信道状态信息会包含在测量报告中发往发射端设备，而缺失子带的信道状态信息则不会发往发射端设备。在这种情况下，为了在接收端设备和发射端设备之间实现缺失子带信道状态信息的一致性，发射端设备也需要基于参考规则参考上报子带中该参考规则所指示的上报子带的信道状态信息得到该缺失子带的信道状态信息。如此一来，接收端设备和发射端设备所获得的缺失子带的信道状态信息是相同的。
为便于理解，可以参考图6和图7来理解本发明实施例提供的待测量频带。在图6和图7中，待测量频带具体体现为上报带宽。载波带宽、带宽部分、子带、上报带宽的具体内容可以参考上文结合图1进行的描述。进一步的，在图6中，上报带宽包含6个子带，分别为上报带宽所横跨的6个子带。在这些子带中，图样1所指示的3个子带为缺失子带，其他3个子带为上报子带。在图7中，上报带宽虽然横跨6个子带，但图样2所指示的子带并非上报带宽的一部分，因此上报带宽仅包含横跨的6个子带中除图样2所指示的子带之外的5个子带。此外，在图7中，图样1所指示的1个子带为缺失子带，其他4个子带 为上报子带。
在上述方法500中，由于需要参考上报子带的信道状态信息来得到缺失子带的信道状态信息，因此缺失子带的信道状态信息应当与上报子带的信道状态信息属于同一类型，该类型的信道状态信息可以是，例如但不限于，CQI、PMI、RI和CRI之中的一种。应注意，在具体实现过程中，接收端设备可以向发射端设备反馈待测量频带所包含子带的多种类型的信道状态信息，其中每种类型的信道状态信息都可以参考方法500进行上报。
如果缺失子带是由接收端设备自行确定的，则本领域的技术人员应当明白，可以在测量报告或者其他消息中包含对缺失子带的指示。在具体实现过程中，上述指示的方式有多种，例如但不限于，隐式指示、显示指示、直接指示、间接指示或者上述指示方式的组合等。举例来说，直接指示是指直接指示待指示信息，例如直接指示缺失子带。间接指示是指通过指示其他信息来指示待指示信息，例如通过指示上报子带来指示缺失子带。上述指示的具体实现方式可以参考现有技术，本发明不做限定。应注意，上述对指示的方式的描述，也适用于本文提及的其他指示。
另一方面，缺失子带也可以由发射端设备指定，并指示给接收端设备。在这种情况下,方法500可以进一步包括：
接收来自发射端设备的缺失子带指示信息，其中所述缺失子带指示信息用于指示所述至少一个缺失子带；
根据所述缺失子带指示信息确定所述至少一个缺失子带。
在具体实现过程中，上述接收来自发射端设备的缺失子带指示信息的步骤可由收发模块304和收发器404来执行，上述根据所述缺失子带指示信息确定所述至少一个缺失子带的步骤可由处理模块302和处理器402来执行。应注意，上述缺失子带指示过程可以作为方法500的一部分，或者将方法500作为上述过程的一部分。
上述缺失子带指示信息可通过如下信令之中的一种进行发送：
物理层信令；
媒体访问控制层信令；
无线资源控制信令。
如果需要频繁或者动态指示缺失子带，则可以优先使用物理层信令来传送缺失子带指示信息。
物理层信令也称为第一层(Layer 1，L1)信令，其通常可以由物理层帧中的控制部分来承载。L1信令的典型例子是LTE标准中定义的物理下行控制信道(Physical Downlink Control Channel，PDCCH)中承载的下行控制信息(Downlink Control Information，DCI)。在一些情况下，L1信令也可以由物理层帧中的数据部分来承载。不难看出，L1信令的发送周期或者信令周期通常为物理层帧的周期，因此这种信令通常用于实现一些动态的控制，以传递一些变化频繁的信息，例如，可以通过物理层信令传送资源分配信息。
媒体访问控制(Media Access Control，MAC)层信令属于第二层(Layer 2)信令，其通常可以由，例如但不限于，第二层帧的帧头来承载。上述帧头中还可能携带，例如但不限于，源地址和目的地址等信息。除帧头外，第二层帧通常还包含帧体。在一些情况下，L2信令也可以由第二层帧的帧体来承载。第二层信令的典型例子是802.11系列标准中MAC帧的帧头中的帧控制(Frame Control)字段中携带的信令，或者一些协议中定义的 MAC控制实体(Control Entity，MAC-CE)。第二层帧通常可以携带在物理层帧的数据部分。上述缺失子带指示信息也可以通过媒体访问控制层信令之外的其他第二层信令发送。
无线资源控制(Radio Resource Control，RRC)信令属于第三层(Layer 3)信令，其通常是一些控制消息，L3信令通常可以携带在第二层帧的帧体中。L3信令的发送周期或者控制周期通常较长，适用于发送一些不会频繁发生变化的信息，例如，在现有的一些通信标准中，L3信令通常用于承载一些配置信息。上述缺失子带指示信息也可以通过RRC信令之外的其他第三层信令发送。
上文所述仅为物理层信令、MAC层信令、RRC信令、第一层信令、第二层信令和第三层信令的原理性描述，有关三种信令的具体细节可以参考现有技术，因此本文不再赘述。
在上文描述的缺失子带的指示方案中，所述缺失子带指示信息用于指示所述至少一个缺失子带，可以具体为逐一指示每个缺失子带，也可以为指示一缺失子带配置方案，该配置方案中记录所述至少一个缺失子带。不难理解，前一种方案指示方式更加灵活，但指示开销较大，后一种方案的指示开销较小，但指示方式相对固定。在采用缺失子带配置方案的情况下，可以在通信标准中约定多种缺失子带配置方案，并且在可以在接收端设备和发射端设备出厂前提前写入这些缺失子带配置方案，以便在接收端设备与发射端设置进行交互的过程中通过传递缺失子带配置方案的索引来指示缺失子带。此外，上述多种缺失子带配置方案也可以是在发射端设备与接收端设备交互过程(例如初始接入过程)中，由发射端设备为接收端设备配置的。在这种情况下，方法500还可以进一步包括：
接收来自发射端设备的缺失子带配置信息，其中所述缺失子带配置信息包含多种缺失子带配置方案，每种配置方案中记录有多个缺失子带；
根据所述缺失子带配置信息确定所述多种缺失子带配置方案。
在具体实现过程中，上述接收来自发射端设备的缺失子带配置信息的步骤可由收发模块304和收发器404来执行，上述根据所述缺失子带配置信息确定所述多种缺失子带配置方案的步骤可由处理模块302和处理器402来执行。应注意，应注意，上述缺失子带配置过程可以作为方法500的一部分，或者将方法500作为上述过程的一部分。
在具体实现过程中，上述缺失子带配置信息可通过如下信令之中的一种进行发送：
物理层信令；
媒体访问控制层信令；
无线资源控制信令。
通常情况下，缺失子带配置信息的发送周期较长，因此可以优选使用媒体访问控制层信令或者无线资源控制信令来传送缺失子带配置信息。
又一方面，也可以在通信标准中预先指定缺失子带。不难理解，相比指示缺失子带的做法，采用在通信标准中预先指定的方式，有助于降低指示所带来的信令开销。
上述测量报告可以通过一条消息进行传送，也可以通过多条消息进行传送，本发明实施例对具体传送方式不做限定。此外，多种同类信息(例如信道状态信息)可以彼此独立的包含在测量报告之中，也可以采用相互关联的方式包含在测量报告之中，还可以采用其他方式包含在测量报告之中。举例来说，上述相互关联的方式可以是差分方式。例如，本发明实施例对具体的包含方式不做限定。应注意，上文所述也适用于本发明实施例涉及的其他信令，例如但不限于上述缺失子带指示信息等。
参考规则规定了如下子规则：
A、信道状态信息可供缺失子带参考的上报子带；
B、如何参考子规则A中的上报子带的信道状态信息得到缺失子带的信道状态信息。
在具体实现过程中，可以根据具体的需要来设计上述子规则A，本发明实施例对上述子规则A的具体内容不做限定。举例来说，上述子规则A可以为，例如但不限于，下列规则之一或者任意组合：
1、与缺失子带在频率上最为接近的上报子带；
2、频率低于该缺失子带的上报子带；
3、频率高于该缺失子带的上报子带；
4、缺失子带所在的连续子带组中的上报子带，其中上述连续子带组中的子带属于待测量频带且待测量频带中除连续子带组中的子带之外的任一子带与连续子带组中的任一子带不连续；
5、与该缺失子带连续的上报子带；
6、频率最高的上报子带；
7、频率最低的上报子带；
例如，将上述方式2与上述方式5进行组合，即可得到如下子规则，与缺失子带连续且频率低于缺失子带的上报子带。此外，还可以通过组合的方式得到多条子规则，并进一步设置这些子规则之间的关系，防止出现不存在符合子规则A的上报子带的情况。例如，通过组合的方式获得子规则X和子规则Y，并且进一步规定，当通过子规则X无法确定上报子带的时候，通过子规则Y来确定上报子带。
不难理解，根据子规则A确定的上报子带可以是一个，也可以是多个。
在具体实现过程中，可以根据具体的需要来设计上述子规则B，本发明实施例对上述子规则B的具体内容不做限定。举例来说，上述子规则B可以是，若根据子规则A确定的上报子带为一个，则将该上报子带的信道状态信息设置为缺失子带的信道状态信息，或者，基于该上报子带的信道状态信息计算缺失子带的信道状态信息。又例如，上述子规则B可以是，若根据子规则A确定的上报子带为多个，则将这些上报子带的信道状态信息的平均值设置为缺失子带的信道状态信息，或者对于每一缺失子带，基于频率高于该缺失子带的某一个或者多个上报子带(例如距离该缺失子带最近的上报子带)的信道状态信息，和/或频率低于该缺失子带的某一个或者多个上报子带(例如距离该缺失子带最近的上报子带)的信道状态信息，通过插值的方式获得该缺失子带的信道状态信息，又或者采用其他方式基于多个上报子带的信道状态信息来计算确实子带的信道状态信息。在计算确实子带的信道状态信息时可以采用多种计算方法，本发明实施例对具体采用的计算方法不做限定。
此外，对于每一缺失子带，接收端设备也可以通过信道估计得到该缺失子带的信道状态信息，但仍然不会发往发射端设备。同时，发射端设备可以自行设置缺失子带的信道状态信息，而不依赖于上述参考规则，换句话说，发射端设备在设置缺失子带的信道状态信息时，可以不考虑实际的信道环境。不难理解，这种设计方案虽然可以降低信道测量带来的反馈开销，但是却在接收端设备和发射端设备之间实现缺失子带信道状态信息的一致性，很可能给传输效果带来不利影响。
在获得缺失子带的信道状态信息后，发射端设备还可以对该信道状态信息进行调整。有关调整的内容已经在上文进行了清楚的描述，因此此处不再赘述。
如果参考规则是由接收端设备自行确定的，则本领域的技术人员应当明白，可以在测量报告或者其他消息中包含对参考规则的指示。
另一方面，上述参考规则也可以由发射端设备进行指示，在这种情况下，方法500可以进一步包括：
接收来自发射端设备的参考规则指示信息，其中所述参考规则指示信息用于指示所述参考规则，所述参考规则为多种参考规则之中的一种；
根据所述参考规则指示信息确定所述参考规则。
应注意，上述参考规则指示过程可以作为方法500的一部分，或者将方法500作为上述过程的一部分
在具体实现过程中，上述参考规则指示信息可通过如下信令之中的一种进行发送：
物理层信令；
媒体访问控制层信令；
无线资源控制信令。
如果需要频繁或者动态指示参考规则，则可以优先使用物理层信令来传送参考规则指示信息。
在具体实现过程中，上述接收来自发射端设备的参考规则指示信息的步骤可由收发模块304和收发器404来执行，上述根据所述参考规则指示信息确定所述参考规则的步骤可由处理模块302和处理器402来执行。
在具体实现过程中，可以在通信标准中约定多种参考规则，并且在接收端设备和发射端设备出厂前提前写入这些参考规则，以便在接收端设备与发射端设置进行交互的过程中通过携带例如参考规则索引的参考规则指示信息来指示参考规则。此外，上述多种参考规则也可以是在发射端设备与接收端设备交互过程(例如初始接入过程)中，由发射端设备为接收端设备配置的。在这种情况下，方法500还可以进一步包括：
接收来自发射端设备的参考规则配置信息，其中所述参考规则配置信息包含上述多种参考规则；
根据所述参考规则配置信息确定所述多种参考规则。
在具体实现过程中，上述接收来自发射端设备的参考规则配置信息的步骤可由收发模块304和收发器404来执行，上述根据所述参考规则配置信息确定所述多种参考规则的步骤可由处理模块302和处理器402来执行。应注意，上述参考规则配置过程可以作为方法500的一部分，或者将方法500作为上述过程的一部分。
在具体实现过程中，上述参考规则配置信息可通过如下信令之中的一种进行发送：
物理层信令；
媒体访问控制层信令；
无线资源控制信令。
通常情况下，参考规则配置信息的发送周期较长，因此可以优选使用媒体访问控制层信令或者无线资源控制信令来传送参考规则配置信息。
此外，还可以在通信标准中预先指定参考规则。不难理解，相比指示参考规则的做法， 采用在通信标准中预先指定的方式，有助于降低指示所带来的信令开销，适用于参考规则不会频繁更改的情形。
在具体实现过程中，方法500还可以进一步包括：
基于信道状态信息组计算信道相关信息，所述信道状态信息组至少包含所述至少一个缺失子带之中的至少一个缺失子带的信道状态信息；

其中，上述基于信道状态信息组计算信道相关信息的步骤可由处理模块302和处理器402来执行，向发射端设备发送所述信道相关信息的步骤可由收发模块304和收发器404来执行。
在具体实现过程中，上述信道状态信息组可以包含缺失子带的信道状态信息，也可以包含上报子带的信道状态信息，或者这些信道状态信息的组合，本发明实施例对上述其他信息不做限定。此外，上述信道相关信息可以是宽带信道状态信息、子带信道状态信息或者其他信息。
上述信道相关信息可以是待测量频带的信道状态信息，即待测量频带的宽带信道状态信息，在这种情况下，基于信道状态信息组计算信道相关信息可以具体为，基于各个上报子带的信道状态信息和各个缺失子带的信道状态信息计算待测量频带的信道状态信息。例如，待测量频带的信道状态信息可以是CQI，各个上报子带的信道状态信息和各个缺失子带的信道状态信息可以是PMI，或者，各个上报子带的信道状态信息和各个缺失子带的信道状态信息也可以是CQI。本领域的技术人员应当明白，除了基于各个上报子带的信道状态信息和各个缺失子带的信道状态信息计算待测量频带的信道状态信息，也可以采用其他方法计算待测量频带的信道状态信息，例如但不限于，将待测量频带作为一个整体，计算其信道状态信息。与此有关的内容属于现有技术，本发明实施例不再赘述。若上述信道相关信息为待测量频带的信道状态信息，且该信道状态信息与各个上报子带的信道状态信息和各个缺失子带的信道状态信息的类型相同，则在上报待测量频带的信道状态信息和每个上报子带的信道状态信息时，可以采用差分方式进行上报。具体来说，可以上报待测量频带的信道状态信息，以及每个上报子带的信道状态信息与待测量频带的信道状态信息之间的差值。
上述信道相关信息还可以是缺失子带的其他信道状态信息，在这种情况下，基于信道状态信息组计算信道相关信息可以具体为，基于缺失子带的信道状态信息计算该缺失子带的其他信道状态信息，且上述信道状态信息与上述其他信道状态信息的类型不同。例如，上述信道状态信息可以是PMI，其他信道状态信息可以是CQI。
又例如，上述信道相关信息可以是缺失子带的其他信息，在这种情况下，基于信道状态信息组计算信道相关信息可以具体为，基于缺失子带的信道状态信息计算该缺失子带的其他信息。该其他信息可以是，例如但不限于缺失子带的信干噪比(Signal to Interference plus Noise Ratio，SINR)。
在具体实现过程中，本发明实施例对信道相关信息的具体内容不做限定。

方法800与方法500相对应，相关技术内容已经在上文结合方法500进行了详细的描述，因此此处不再赘述。
鉴于下一代无线通信标准尚未规定待测量频带的子带的信道状态信息的具体传输方法，本发明实施例还提供了一种上行控制信息(Uplink Control Information，UCI)上报方法。下面就结合附图对该方法进行详细描述。
图9是依照本发明一实施例的上行控制信息发送方法900的示范性流程图。在具体实现过程中，方法900可由于接收端设备来执行，该接收端设备可以由图3所示的通信设备300和图4所示的通信设备400来实现。
步骤902，生成上行控制信息，其中，该上行控制信息包含第一部分和第二部分，所述第一部分和第二部分独立编码，且所述第一部分对应的信息比特的数量是固定的，且第一部分包含用于指示第二部分所对应的信息比特的数量的信息，所述第二部分包含待测量频带的M个子带的信道状态信息，其中所述待测量频带包含N个子带，1≤M≤N；
步骤904，向发射端设备发送所述上行控制信息。
在具体实现过程中，步骤902可由处理模块302和处理器402来执行，步骤904可由收发模块304和收发器404来执行。
本领域的技术人员应当明白，UCI通常包含调度请求、信道状态信息和重传控制相关信息(例如ACK和NACK)，这些信息的具体内容可以参考现有技术，本文不再赘述。UCI在进行传送之前需要进行编码和调制等传输处理，从而由比特形式转换成为调制符号形式进行传送。为便于描述本发明实施例提供的上行控制信息上报方法，在描述该上报方法时提及的UCI所包含的信息时，如果没有特殊说明，或者，如果未与其在相关描述中的实际作用或者内在逻辑相抵触，均指代UCI所包含的尚未进行上述编码和调制等传输处理的信息比特，即原始的信息比特，或者信息比特载荷。以长期演进(Long Term Evolution，LTE)标准为例，UCI所包含的ACK或者NACK的信息比特的数量可以为1或者2，分别对应1个码字(Codeword)或者两个码字的情形。
在本发明实施例提供的技术方案中，上行控制信息可以包含两个部分，分别为第一部分和第二部分，且第一部分和第二部分分别独立进行编码。更进一步的，第一部分所包含的信息比特的数量是固定的，并且第一部分包含用于指示第二部分所包含信息比特的数量的信息。特别的，第二部分还包含待测量频带的M个子带的信道状态信息，其中所述测量频带包含N个子带，1≤M≤N。此外，第一部分还可以包含待测量频带的信道状态信息，即宽带信道状态信息。其中，子带信道状态信息的类型与宽带信道状态信息的类型可以相同，也可以不同。更进一步的，二者均可以为CQI、PMI、RI和CRI之中的一种。此外，所述M个子带的信道状态信息应当理解为属于同一类型。
由上述UCI的结构不难看出，可以将待测量频带的信道状态信息包含在第一部分，而将待测量频带的子带的信道状态信息包含在第二部分。同时，待测量频带所包含的子带可以包含缺失子带，也可以不包含缺失子带。在包含缺失子带的情况下，M<N。在不包含缺失子带的情况下，M＝N。
由此可见，本发明实施例提供了一种传输待测量频带的子带的信道状态信息的方法。 应注意，在具体实现过程中，接收端设备可以向发射端设备反馈待测量频带所包含子带的多种类型的信道状态信息，其中每种类型的信道状态信息都可以参考方法900进行上报。此外，接收端设备可以向发射端设备反馈待测量频带的多种类型的信道状态信息，其中每种类型的信道状态信息都可以参考方法900进行上报。不难理解，上文所述的待测量频带的测量报告即可包含在上行控制信息中。
图10是依照本发明一实施例的上行控制信息接收方法1000的示范性流程图。在具体实现过程中，方法900可由于发射端设备来执行，该发射端设备可以由图3所示的通信设备300和图4所示的通信设备400来实现。
步骤1002，接收上行控制信息，其中，该上行控制信息包含第一部分和第二部分，所述第一部分和第二部分独立编码，且所述第一部分对应的信息比特的数量是固定的，且第一部分包含用于指示第二部分所对应的信息比特的数量的信息，所述第二部分包含待测量频带的M个子带的信道状态信息，其中所述待测量频带包含N个子带，1≤M≤N；
步骤1004，根据所述上行控制信息确定待测量频带的M个子带的信道状态信息。在具体实现过程中，如果M<N，可以认为存在缺失子带，则可以依照上文描述的技术方案进一步确定缺失子带的信道状态信息。
在具体实现过程中，步骤1002可由收发模块304和收发器404来执行，步骤1004可由处理模块302和处理器402来执行。
方法1000与方法900相对应，相关技术内容已经在上文结合方法900进行了详细的描述，因此此处不再赘述。
在上述实施例中，可以全部或部分地通过软件、硬件、固件或者其任意组合来实现。当使用软件实现时，可以全部或部分地以计算机程序产品的形式实现。所述计算机程序产品包括一个或多个计算机指令。在计算机上加载和执行所述计算机程序指令时，全部或部分地产生按照本发明实施例所述的流程或功能。所述计算机可以是通用计算机、专用计算机、计算机网络、或者其他可编程装置。所述计算机指令可以存储在计算机可读存储介质中，或者从一个计算机可读存储介质向另一个计算机可读存储介质传输，例如，所述计算机指令可以从一个网站站点、计算机、服务器或数据中心通过有线(例如同轴电缆、光纤、数字用户线(DSL))或无线(例如红外、无线、微波等)方式向另一个网站站点、计算机、服务器或数据中心进行传输。所述计算机可读存储介质可以是计算机能够存取的任何可用介质或者是包含一个或多个可用介质集成的服务器、数据中心等数据存储设备。所述可用介质可以是磁性介质，(例如，软盘、硬盘、磁带)、光介质(例如，DVD)、或者半导体介质(例如固态硬盘Solid State Disk(SSD))等。
综上所述，以上仅为本发明的实施例而已，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
