无线通信系统被广泛地部署以提供诸如电话、视频、数据、消息传送和广播之类的各种电信服务。典型的无线通信系统可以采用能够通过共享可用的系统资源(例如，带宽、发射功率)来支持与多个用户的通信的多址技术。这种多址技术的示例包括码分多址(CDMA)系统、时分多址(TDMA)系统、频分多址(FDMA)系统、正交频分多址(OFDMA)系统、单载波频分多址(SC-FDMA)系统和时分同步码分多址(TD-SCDMA)系统。
在各种电信标准中已采纳这些多址技术，以提供使得不同的无线设备能够在城市、国家、地区、甚至全球层面上进行通信的公共协议。一种新兴的电信标准的例子是长期演进(LTE/LTE-A)。LTE/LTE-A是由第三代合作伙伴计划(3GPP)发布的通用移动通信系统(UMTS)移动标准的增强集合。LTE/LTE-A被设计为通过提高谱效率、降低费用、改善服务、利用新频谱来更好地支持移动宽带互联网接入，并且与在下行链路(DL)上使用OFDMA、在上行链路(UL)上使用SC-FDMA以及使用多输入多输出(MIMO)天线技术的其它开放标准进行更好地整合。但是，随着对移动宽带接入的需求持续增加，存在对LTE技术中的进一步改进的需求。当前，世界范围内已着手开始对第五代通信技术(5th-Generation，5G)的研究了，5G是一种多技术融合的通信，通过技术的更迭和创新来满足广泛的数据、连接业务的需求。
需要注意的是，现有的长期演进(Long Term Evolution，LTE)系统中，基站实行下行信道测量后，终端(如手机)会根据数据传输方案向基站进行信道状态信息(Channel State Information，CSI)上报。目前，支持两种形式的CSI上报：周期性CSI上报和非周期性CSI上报。
进一步地，周期性CSI上报，是终端周期性地向基站进行发送；其中，基站通过CQI-reportAperiodic-r10来配置周期性CSI上报的相关参数，且每个下行载波单元都可以独立地配置各自的周期性CSI参数。非周期CSI上报，是终端非周期性地向基站进行发送，从基站的角度来看，只有当小区有下行需要发送时，才会要求终端发送非周期性CSI；其中，基站通过CQI-reportAperiodic-r10来配置非周期CSI上报的相关参数。周期性CSI上报占用较多信道资源，而非周期CSI底层信令交互较多，同样会占用部分的资源，尤其用于信道变化幅度不明显的场景中时，严重降低了频谱的利用率。
发明内容
本发明实施例提供一种信息冲突处理方法，以减少信道资源的占用，提高频谱利用率。
本发明实施例提供了一种信息冲突处理方法，包括：
接收基站所发送的参考信号并对参考信号进行测量；
根据测量结果准备向基站发送的半静态信道状态信息；
确定发送该半静态信道状态信息的子帧；
根据数据的缓存情况生成调度请求；
确定承载调度请求的子帧；
若发送该半静态信道状态信息的子帧和承载调度请求的子帧相同，则确定半静态信道状态信息和调度请求冲突；
以避让的方式消除发送半静态信道状态信息和调度请求的冲突。
本发明实施例提供了一种终端，包括：
接收单元，用于接收基站所发送的参考信号并对参考信号进行测量；
准备单元，用于根据测量结果准备向基站发送的半静态信道状态信息；
生成单元，用于根据数据的缓存情况生成调度请求；
确定单元，用于确定发送该半静态信道状态信息的子帧及承载调度请求的子帧；
确定单元还用于若发送半静态信道状态信息的子帧和承载调度请求的子 帧相同、则确定半静态信道状态信息和调度请求冲突；
消除单元，用于以避让的方式消除发送半静态信道状态信息和调度请求的冲突。
本发明实施例先接收基站发送的参考信号并对其进行测量，再根据测量结果准备向基站发送的半静态信道状态信息，之后确定发送该半静态信道状态信息的子帧，接着根据数据的缓存情况生成调度请求并确定承载调度请求的子帧，若发送半静态信道状态信息的子帧和承载调度请求的子帧相同，则确定两者的发送存在冲突，并以避让的方式消除该冲突。本实施例采用半静态信道状态信息向基站进行上报，能够消除了在同一子帧上发送半静态信道状态信息和调度请求的冲突，从而降低了信道资源的占用。尤其是在信道变化幅度不明显的场景中，半静态信道状态信息的上报方式明显地提高了频谱的利用率。

具体实现中，本发明实施例中描述的终端包括但不限于诸如具有触摸敏感表面(例如，触摸屏显示器和/或触摸板)的移动电话、膝上型计算机或平板计算机之类的其它便携式设备。还应当理解的是，在某些实施例中，所述设备并非便携式通信设备，而是具有触摸敏感表面(例如，触摸屏显示器和/或触摸板)的台式计算机。
在接下来的讨论中，描述了包括显示器和触摸敏感表面的终端。然而，应当理解的是，终端可以包括诸如物理键盘、鼠标和/或控制杆的一个或多个其它物理用户接口设备。
本文描述的技术可以用于各种无线通信网络，诸如码分多址(Code  Division Multiple Access，CDMA)网络、时分多址(Time Division Multiple Access，TDMA)网络、频分多址(Frequency Division Multiple Access，FDMA)网络、正交频分多址(Orthogonal Division Multiple Access，OFDMA)网络、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)网络以及其它网络。术语“网络”和“系统”通常交换使用。CDMA网络可以实现诸如通用陆地无线接入(Universal Telecommunication Radio Access，UTRA)、电信工业协会(Telecommunications Industry Association，TIA)的之类的无线技术。UTRA技术包括宽带CDMA(WCDMA)和CDMA的其它变型。技术包括来自电子工业协会(Electronic Industries Association，EIA)和TIA的IS-2000、IS-95和IS-856标准。TDMA网络可以实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线技术。OFDMA系统可以实现诸如演进型UTRA(E-UTRA)、超移动宽带(Ultra Mobile Broadband，UMB)、IEEE802.11(无线保真，Wi-Fi)、IEEE802.16(全球微波互联接入—Worldwide Interoperability for Microwave Access，WiMAX)、IEEE802.20、Flash-OFDMA之类的无线技术。UTRA和E-UTRA技术是通用移动电信系统(UMTS)的一部分。3GPP长期演进(Long Term Evolution，LTE)和高级LTE(LTE-A)是使用E-UTRA的UMTS的较新版本。在来自名为“第三代合作伙伴计划”(3GPP)的组织的文档中描述了UTRA、E-UTRA、UMTS、LTE、LTE-A和GSM。在来自称为“第三代合作伙伴计划2”(3GPP2)的组织的文档中描述了UMB。本文中所描述的技术可以用于上面所提到的无线网络和无线接入技术，以及其它无线网络和无线接入技术(例如下一代5G网络，有时也被称作NR系统)。为了清楚起见，在下面该技术的某些方面是针对LTE或LTE-A(或者总称为“LTE/-A”)进行描述的，并且在下面的许多描述中使用这种LTE/-A术语。
需要说明的是，无线通信网络可以包括能够支持多个终端(也叫用户设备)的通信的多个基站。终端可以通过下行链路和上行链路与基站进行通信。下行链路(或前向链路)是指从基站到终端的通信链路，而上行链路(或反向链路)是指从终端到基站的通信链路。
终端(例如，蜂窝电话或者智能电话)可以利用无线通信系统来发射和接收数据以用于双路通信。终端可以包括用于数据发射的发射机以及用于数据接收的接收机。对于数据发射，发射机可以利用数据对发射本地振荡器(Local Oscillator，LO)信号进行调制以获得经调制的射频(Radio Frequency，RF)信号，对经调制的RF信号进行放大以获得具有恰当发射功率级别的输出RF信号，并且经由天线将输出RF信号发射给基站。对于数据接收，接收机可以经由天线来获得所接收的RF信号，放大并利用接收LO信号将所接收的RF信号下变频，并且处理经下变频的信号以恢复由基站发送的数据。
终端可以支持与不同无线电接入技术(Radio Access Technology，RAT)的多个无线系统的通信(例如LTE/LTE-A和NR)。每个无线系统可能具有某些特性和要求，能够高效地支持利用不同RAT的无线系统的同时通信。终端可以包括移动台、终端、接入终端、订户单元、站点，等等。终端还可以是蜂窝电话、智能电话、平板计算机、无线调制解调器、个人数字助理(Personal Digital Assistant，PDA)、手持式设备、膝上型计算机、智能本、上网本、无绳电话、无线本地回路(wireless local loop，WLL)站点、蓝牙设备，等等。终端可以能够与无线系统进行通信，还可以能够从广播站、一个或多个全球导航卫星系统(Global Navigation Satellite System，GNSS)中的卫星等接收信号。终端可以支持用于无线通信的一个或多个RAT，诸如GSM、WCDMA、CDMA2000、LTE/LTE-A、802.11，等等。术语“无线电接入技术”、“RAT”、“无线电技术”、“空中接口”和“标准”经常可互换地被使用。
需要说明的是，在LTE/LTE-A系统中，上/下行载波分别采用单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)/OFDM以及循环前缀(Cyclic Prefix，CP)。在5G标准中，示例性的，可以对上下行载波进行统一，即上行链路与下行链路均采用OFDM以及CP。另外示例性的，5G中的RB可以做如下配置，1个资源块包含12个子载波，子载波间隔以15kHz为基准，子载波间隔可以是15kHz的N(N＝2^n)倍，或者也可以固定为子载波间隔为75kHz。具体而言，传统LTE小区工作在频段上的带宽是由RB构成，RB分别具有固定的子载波间隔和符号长度，比如正常CP下，频域上的大小 为180KHz(即：12个15KHz子载波间隔)，时域上，包括7个符号，一个符号的长度约等于71.5us。而在下一代5G移动通信技术中(例如NR系统中)，不同子载波可以基于业务类型不再具有固定的子载波间隔和固定的符号长度(可以动态变化)。为区别于传统LTE系统中的RB概念，NR系统新定义了“numerology”(参考数值)的概念，它主要包括子载波间隔、CP长度和TTI(Transmission Time Interval，传输时间间隔)长度等。目前，NR系统共定义了三种业务类型，分别是eMBB、URLLC和mMTC，不同业务类型的“numerology”类型也可以不同，意味不同类型的子载波间隔、CP长度或TTI长度可能有所不同。示例性的，可以定义下一代移动通信将会支持最大为100MHz的单载波带宽。一个资源块RB在频域上的大小变为900KHz(即：12个75KHz子载波间隔)，而在时域上支持0.1ms。一个无线帧的长度是10ms，但是由50个子帧构成，每个子帧的长度为0.2ms。需要说明的是，本文通篇所述的适用于所述NR业务的信号类型，可以是指包括载波间隔、CP长度和TTI长度等相关参数中的至少一种参数的配置。
终端可以支持载波聚合，载波聚合是在多个载波上的操作。载波聚合还可以被称为多载波操作。载波可以指代被使用用于通信的一个范围的频率并且可以与某些特性相关联。例如，载波可以与描述该载波上的操作的系统信息和/或控制信息相关联。载波还可以被称为分量载波(CC)、频率信道、小区，等等。一个频带可以包括一个或多个载波。示例性的，每个载波可以覆盖多至20MHz。终端可以被配置具有一个或两个频带中的多至5个载波。终端可以包括多个接收机，以在不同频率处同时接收多个下行链路信号。这些多个下行链路信号可以由一个或多个基站在用于载波聚合的不同频率处在多个载波上发送。每个接收机可以接收在一个或多个载波上发送给终端的一个或多个下行链路信号。
在载波聚合场景中操作的终端被配置为在相同的载波上聚合多个载波的某些功能，例如控制和反馈功能，该载波可以被称为主载波或主分量载波。依靠主载波支持的其余载波被称为相关联的辅载波或辅分量载波。主载波是由主小区发送的。辅载波是由辅小区发送的。
在一些实施例中，可以有多个主载波。另外，可以在不影响终端的基本操作的情况下添加或移除辅载波。在载波聚合中，可以将控制功能从至少两个载波聚合到一个载波上以形成主载波和一个或多个相关联的辅载波。可以针对主载波和每个辅载波建立通信链路。随后，可以基于主载波来控制通信。在载波聚合中，终端还可以向服务基站发送用于指示所支持的频带和载波聚合带宽类别的终端能力信息消息。根据终端能力，服务基站可以使用RRC连接重配置过程来配置终端。RRC连接重配置过程允许服务基站添加和移除在辅载波上进行发送的服务基站的辅小区(当前最多四个辅小区)，以及修改在主载波上进行发送的服务基站的主小区。在切换过程中，服务基站可以使用RRC连接重配置过程来添加和移除目标主小区处的辅小区。服务基站可以使用激活/去激活MAC控制元素来激活或去激活辅小区的数据传输。当前，终端监测来自主小区的主信息块(MIB)和系统信息块SIB。主小区负责向终端发送辅小区的MIB和一些SIB。主小区通过无线资源配置公共辅小区(RadioResourceConfigCommonSCell)信息元素和无线资源专用辅小区(RadioResourceDedicatedSCell)信息元素来发送辅小区MIB和一些SIB。
需要特别说明的是，下面本发明各实施例中对某种具体网络架构进行的描述只是一种示例(例如LTE/LTE-A)，而不应理解为限定。本发明所公开的方法和装置同样可以应用到后续演进的(例如：下一代5G)的网络架构中。示例性的，其中各网元和接口的描述如下：
移动性管理实体(Mobility Management Entity，MME)/服务网关(Serving GateWay，S-GW)：MME是第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)LTE中的关键控制节点，属于核心网网元或核心网设备，主要负责信令处理部分，即控制面功能，包括接入控制、移动性管理、附着与去附着、会话管理功能以及网关选择等功能。S-GW是3GPP LTE中核心网的重要网元，主要负责用户面数据传输，以及用户数据转发、路由切换等用户面功能，即在MME的控制下进行数据包的路由和转发。eNB：eNodeB(eNB)可以是与终端通信的站，并且也可以称为基站、节点B、接入点、接入网设备等。每个eNB可以针对特定的地理区域提供通信覆盖。在3GPP中，术语“小 区”根据使用该术语的上下文可以指eNB的这种特定的地理覆盖区域和/或服务于该覆盖区域的eNB子系统的这种特定的地理覆盖区域。eNB主要负责空口侧的无线资源管理、服务质量(QoS，Quality of Service)管理、数据压缩和加密等功能。往核心网侧，eNB主要负责向MME转发控制面信令以及向S-GW转发用户面业务数据。eNB可以针对宏小区、微微小区、毫微微小区和/或其它类型的小区提供通信覆盖。宏小区通常覆盖相对较大的地理区域(例如，半径为几千米的范围)，并且可以允许由具有与网络提供商的服务签约的终端无限制的接入。微微小区通常覆盖相对较小的地理区域，并且可以允许由具有与网络提供商的服务签约的终端无限制的接入。毫微微小区通常也覆盖相对较小的地理区域(例如，家庭)，并且除了无限制的接入以外还可以提供由具有与毫微微小区关联的终端的受限的接入(例如，封闭用户组(Closed Subscriber Group，CSG)中的终端、家庭中的用户的终端等)。宏小区的eNB可被称为宏eNB。微微小区的eNB可被称为微微eNB。以及，毫微微小区的eNB可被称为毫微微eNB或家庭eNB。需要说明的是，eNB可以支持一个或多个(例如，三个)小区(其还称为扇区)。
终端：终端是LTE中通过eNB接入网络侧的设备，例如可以是手持终端、笔记本电脑或是其他可以接入网络的设备。当终端需要在特定信道传输上行数据时(例如，物理上行共享信道，英文：Physical Uplink Shared Channel，简称：PUSCH)，上述终端需要告知eNB，上述终端有上行数据需要传输，eNB得知终端需要传输上下数据之后，针对上述终端进行上行数据调度。
S1接口：是eNB与核心网之间的标准接口。其中eNB通过S1-MME接口与MME连接，用于控制信令的传输；eNB通过S1-U接口与S-GW连接，用于用户数据的传输。其中S1-MME接口和S1-U接口统称为S1接口。
X2接口：eNB与eNB之间的标准接口，用于实现基站之间的互通。
Uu接口：Uu接口是终端与基站eNB之间的无线接口，终端通过Uu接口接入到LTE网络。
3GPP标准组织在TSGRAN#65次全会中通过了基于LTE(Long TermEvolution，长期演进)的LAA(Licensed-AssistedAccess，辅助接入)的研究 项目立项，该项目主要是研究在非授权频谱上如何部署LTE网络，从而达到公平有效地利用非授权频谱，提高LTE系统的数据传输速率的目的。LTE对非授权频谱的使用有两种方式，一种是：仅在下行数据传输时使用非授权频谱；另一种是：在上行和下行数据传输时均可以使用非授权频谱，上行和下行以时分方式复用的方式在同一个非授权载波上。需要特别说明的是，本发明各实施例并不限定于LTE网络，而是可以用在未来网络(例如5G)中的LAA系统中，且授权频谱和非授权频谱可以以载波聚合的形式来进行配置。
请参考图1，是本发明第一实施例提供一种信息冲突处理方法的示意流程图。如图所示，该方法主要包括：
S101，接收基站所发送的参考信号并对该参考信号进行测量。具体地，终端先进行小区搜索、获取小区系统信息及随机接入等，以建立终端与基站之间的通信连接，再通过终端接收基站发送的业务传输需求和携带参考信号的传输数据块，并对该参考信号进行测量。其中，参考信号包括公共参考信号(Common Reference Signal，CRS)和信道状态参考信号(Channel State Information-Reference Signal，CSI-RS)。具体的，终端可以根据基站下发的控制信令中所指示的参考信号的测量方式来对参考信号进行测量，并按照上述控制信令中所指示的反馈形式来进行上报。例如，基站可以支持多种形式的信道状态信息(Channel State Information，CSI)上报：包括周期性CSI上报、非周期性CSI上报或者半静态CSI上报。进一步地，周期性CSI上报，是终端周期性地向基站进行发送；其中，基站可以通过CQI-reportAperiodic-r10来配置周期性CSI上报的相关参数，且每个下行载波单元都可以独立地配置各自的周期性CSI参数。非周期CSI上报，是终端非周期性地向基站进行发送，从基站的角度来看，只有当小区有下行需要发送时，才会要求终端发送非周期性CSI；其中，基站可以通过CQI-reportAperiodic-r10来配置非周期CSI上报的相关参数。周期性CSI上报占用较多信道资源，而非周期CSI底层信令交互较多，同样会占用部分的资源，尤其用于信道变化幅度不明显的场景中时，严重降低了频谱的利用率。采用半静态CSI上报能够有效的解决上述问题。当基站 通过控制信令指示终端进行半静态CSI上报时(例如可以在RRC连接初始建立时)，终端可以对基站的控制信令进行识别以确定是周期性CSI上报、非周期性CSI上报或者半静态CSI上报中的哪一种上报方式。当终端确定基站所指示的为半静态CSI上报方式时，自收到上述基站的指示后一段固定的时间内，都按照该指示进行CSI上报；直到终端接收到基站发送的新的上报指示，则终端按照新的指示的要求进行CSI上报。相区分的，当终端确定基站所指示的为周期性CSI上报方式时，则终端确定基站指示上报的周期时间点(例如，每两个子帧)，按照该周期时间点进行CSI上报。示例性的，如果当前终端正在执行非周期性CSI上报方式或半静态CSI上报方式，终端进一步接收到基站发送的非周期性CSI方式的上报指示，则终端不再执行非周期性CSI上报方式或半静态CSI上报方式，而是执行非周期性CSI方式的上报方式。
S102，根据测量结果准备向基站发送的半静态信道状态信息(Semi-Persistent Channel State Information)。具体地，终端对CRS及CSI-RS等参考信号进行测量，例如对CSI-RS进行测量得知需要发送该参考信号对应的半静态信道状态信息，则终端开始准备该半静态信道状态信息。其中，半静态信道状态信息的上报与CSI-RS在时频资源块中的位置有关。半静态信道状态信息上报机制类似于LTE中的半静态调度机制，基站在初始状态下通过控制信令指示终端对基站发送的参考信号进行测量，以使终端获得当前的信道状态信息，终端可以对该控制信令进行识别，如是半静态信道状态信息，则保存当前的指示信息，每隔固定的周期在相同的时频资源位置上进行该CSI的发送。
S103，确定发送该半静态信道状态信息的子帧。具体地，终端根据基站发送的控制信令确定发送半静态信道状态的子帧。
S104，根据数据的缓存情况生成调度请求并确定承载调度请求的子帧。具体地，当终端需要向基站发送数据的时候，例如，终端的缓存器内有数据的时候，会先生成一调度请求，并确定承载该调度请求的子帧，之后向基站发起该调度请求。
S105，判断两子帧是否相同，若是，执行步骤S106，反之，执行步骤S108。
S106，确定半静态信道状态信息和调度请求冲突。具体地，若确定发送半 静态信道状态信息的子帧为子帧1，确定承载调度请求的子帧为子帧2，判断子帧1和子帧2是否为同一子帧，若为同一子帧，则确定半静态信道状态信息和调度请求的发送存在冲突。否则，则说明两者的发送不存在冲突。
S107，以避让方式消除发送半静态信道状态信息和调度请求的冲突。需要说明的是，该部分内容将在下面的实施例进行详述，故在此不再赘述。
S108，发送半静态信道状态信息。即，在发送半静态信道状态信息的子帧1上不需要发送调度请求，因此不存在两者的发送冲突，故直接在该子帧1发送半静态信道状态信息即可。
本发明实施例先接收基站发送的参考信号并对其进行测量，再根据测量结果准备向基站发送的半静态信道状态信息，之后确定发送该半静态信道状态信息的子帧，接着根据数据的缓存情况生成调度请求并确定承载调度请求的子帧，若发送半静态信道状态信息的子帧和承载调度请求的子帧相同，则确定两者的发送存在冲突，并以避让的方式消除该冲突。本实施例采用半静态信道状态信息向基站进行上报，同时消除了在同一子帧上发送半静态信道状态信息和调度请求的冲突，从而降低了信道资源的占用。尤其是在信道变化幅度不明显的场景中，半静态信道状态信息的上报方式明显地提高了频谱的利用率。
再请参考图2，是本发明第二实施例提供一种信息冲突处理方法的示意流程图。在本实施例中，主要讨论小区及移动终端支持载波聚合技术、且不丢弃半静态信道状态信息的情形。如图所示，该方法可包括以下步骤：
S201，搜索并获取小区的系统信息。具体地，小区及移动终端是支持载波聚合功能的。移动终端通过小区搜索以获取小区的系统信息，其中，该系统信息包括主同步信号(Primary Synchronization Channel，PSS)、辅同步信号(Secondary Synchronization Channel，SSS)及物理层小区身份信息(Physical-layer Cell Identity，PCI)等。
S202，向基站发起随机接入请求以建立与基站的通信连接。具体地，获取小区的系统信息后，终端向基站发起随机接入请求，从而建立终端与基站之间的通信连接。
S203，判断是否接入成功，若是，则执行步骤S204，反之，则执行步骤 S102。具体地，基站接收到终端发送的随机接入请求后，同意该请求则会建立基站与终端之间的通信连接，即代表接入成功，并进入步骤S204。若基站不同意该请求，则不会建立基站与终端之间的通信连接，即代表接入失败，重新执行步骤S202，终端会再次向基站发起随机接入请求。
S204，接收基站发送的业务传输需求和传输数据块，该传输数据块中携带参考信号。具体地，随机接入成功之后，基站有业务需要传输至终端时，会通过物理下行链路控制信道(Physical Downlink Control Channel，PDCCH)通知终端，并发送传输数据块给终端。进一步地，基站通过不同的下行控制信息(Downlink Control Information，DCI)格式通知终端，同时在不同的传输数据块(即资源块，Resource Block，RB)上夹杂不同的参考信号，以方便终端对当前信道进行估计。其中，该参考信号包括公共参考信号(Common Reference Signal，CRS)和信道状态参考信号(Channel State Information-Reference Signal，CSI-RS)。
S205，对该参考信号进行测量并根据测量结果准备向基站发送的半静态信道状态信息。具体地，终端对CRS及CSI-RS等参考信号进行测量，例如对CSI-RS进行测量得知需要发送该参考信号对应的半静态信道状态信息，则终端开始准备该半静态信道状态信息(Channel State Information，CSI)。其中，半静态信道状态信息的上报与CSI-RS在时频资源块中的位置有关。半静态信道状态信息上报机制类似于LTE中的半静态调度机制，基站在初始状态下通过控制信令指示终端对基站发送的参考信号进行测量，以使终端获得当前的信道状态信息，终端可以对该控制信令进行识别，如是半静态信道状态信息，则保存当前的指示信息，每隔固定的周期在相同的时频资源位置上进行该CSI的发送。进一步地，半静态CSI可以是RI(Rank Indicator，秩指示)、PMI(Pre-Coding Matrix Indicator，预编码矩阵指示)、CQI(Channel Quality Indicator，信道质量指示)中的一种或任意组合。
S206，确定发送该半静态信道状态信息的子帧。具体地，终端根据基站发送的控制信令确定发送半静态信道状态的子帧。
S207，根据数据的缓存情况生成调度请求并确定承载调度请求的子帧。具 体地，当终端需要向基站发送数据的时候，例如，终端的缓存器内有数据的时候，会先生成一调度请求，并确定承载该调度请求的子帧，之后向基站发起该调度请求。
S208，判断两子帧是否相同，若是，则执行步骤S209，反之，则执行步骤S211。
S209，确定半静态信道状态信息和调度请求冲突。具体地，若确定发送半静态信道状态信息的子帧为子帧1，确定承载调度请求的子帧为子帧2，判断子帧1和子帧2是否为同一子帧，若为同一子帧，则确定半静态信道状态信息和调度请求的发送存在冲突。否则，则说明两者的发送不存在冲突。
S210，在该子帧对应的主载波上通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)发送调度请求，在该子帧对应的辅载波上通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)发送半静态信道状态信息。需要说明的是，在第五代移动通信中，当在同一子帧上需要同时发送半静态CSI及SR时，在该子帧对应的辅载波上用来发送半静态CSI的信道目前尚未公布，因此，本实施例中，先暂定以PUSCH来发送半静态CSI，但不以此为限，实际发送半静态CSI的信道以第五代移动通信所公布的为准。
S211，发送半静态信道状态信息。即，在发送半静态信道状态信息的子帧1上不需要发送调度请求，因此不存在两者的发送冲突，故直接在该子帧1发送半静态信道状态信息即可。
本发明实施例以支持载波聚合功能的小区及终端为背景，先通过终端进行小区搜索、获取小区系统信息及随机接入等，以建立终端与基站之间的通信连接，再通过终端接收基站发送的业务传输需求和携带参考信号的传输数据块，之后终端对参考信号进行测量以准备向基站发送的半静态CSI及确定发送半静态CSI的子帧，接着，根据数据的缓存情况生成调度请求并确定承载调度请求的子帧，若发送半静态信道状态信息的子帧和承载调度请求的子帧相同，则确定两者的发送存在冲突，并在该子帧对应的主载波上通过PUCCH发送SR，在辅载波上通过PUSCH发送半静态CSI，从而消除上述冲突。本实施例采用半静态信道状态信息向基站进行上报，同时消除了在同一子帧上发送半静态信 道状态信息和调度请求的冲突，从而降低了信道资源的占用。尤其是在信道变化幅度不明显的场景中，半静态信道状态信息的上报方式明显地提高了频谱的利用率，从而可以更好地适应第五代移动通信系统。此外，本实施例中，该解决方法还结合了载波聚合技术，从而提高了系统的整体性能。

S310，若终端同时配置物理上行控制信道和物理上行共享信道，则在子帧的物理上行控制信道发送调度请求，在子帧的物理上行共享信道发送半静态信道状态信息。具体地，若终端同时配置了PUCCH和PUSCH，则在子帧1的PUCCH上发送SR，在子帧1的PUSCH上发送半静态CSI，即通过不同的信道分别发送半静态CSI和SR。
S311，发送半静态信道状态信息。即，在发送半静态信道状态信息的子帧1上不需要发送调度请求，因此不存在两者的发送冲突，故直接在该子帧1发送半静态信道状态信息即可。

S410，若终端未同时配置物理上行控制信道和物理上行共享信道，或者终端同时配置物理上行控制信道和物理上行共享信道，但未使用物理上行共享信道，则在该子帧的物理上行控制信道上发送调度请求及丢弃半静态信道状态信 息。具体地，若终端没有同时配置PUCCH和PUSCH，例如仅配置了PUCCH，则在子帧的PUCCH上只发送SR，而丢弃半静态CSI。若终端虽然同时配置了PUCCH和PUSCH，但并未使用PUSCH，则在PUCCH上至发送SR，而丢弃半静态CSI。终端是否同时配置PUCCH和PUSCH，以及是否同时使用PUCCH和PUSCH是跟终端自身的发射功率相关的。如果终端的发射功率较高，终端则可同时配置PUCCH和PUSCH，以及同时使用PUCCH和PUSCH。若终端的发射功率不高，为了获得与PUSCH和PUCCH中只有一个被发送时相同的接收可靠性，终端可以仅在PUCCH，或者仅在PUCCH上进行信号发送。
