现有的无线通信包括在licensed频段(即授权频段)上和在Unlicensed频段(即免授权频段)上进行的无线通信，其中，在licensed频段上进行的无线通信是指运营商通过部署无线接入网设备(如基站)，和核心网设备(如归属位置寄存器，Home Location Register，缩写为HLR)等，为用户终端(如手机)提供通信服务的系统。例如，现在的移动通信运营商(如中国移动)提供的通信，这类无线通信所占用的频段是被某移动通信运营商(下文称为运营商)单独使用，而运营商针对该频段资源进行管理和优化(例如控制工作在该频段的接入设备的密度、发送功率、天线倾角等)，从而保证在该频段所提供的无线通信服务的可靠性和有效性。
而在Unlicensed频段上进行的无线通信，例如WiFi(Wireless Fidelity，即无线保真)，是国际电工组织IEEE(Institute of Electrical and Electronics Engineers，美国电气电子工程师学会)开发的802.11系列技术的一个统称，如802.11a/g/n/ac等。WiFi主要应用于本地无线通信，通常情况下覆盖相对较小，是一种简单并且相对低价的无线通信手段。WiFi起初的版本工作在2.4GHz的频率上，但由于2.4GHz频段上的可用带宽较小，而工作在2.4GHz频段上的无线发射设备又较多，导致了在2.4GHz上工作的WiFi性能下降。WiFi在后来的版本上发掘了新的通信频率5GHz(注：此处所述5GHz不指 单个频段，而是指在5GHz附近的各个频段，可以理解为从4.9GHz～5.9GHz均为此处所述5GHz频段)。
随着现有技术的不断发展，目前的移动通信系统已经发展到第四代移动通信系统，为国际标准化组织3GPP(The third Generation Partnership Project)制定的长期演进(Long Term Evolution/Long Term Evolution-Advanced，LTE/LTE-A)。为了解决不断增长的数据流量的需求和日益紧缺的无线频率的矛盾，3GPP日前开始了将LTE系统应用在免授权频段上的研究工作，旨在为LTE系统增加可用带宽。3GPP中目前讨论的辅助授权接入系统(LAA,Licensed Assisted Access)主要通过载波聚合方式(CA,Carrier Aggregation)将授权频段和免授权频段聚合在一起，将LTE系统扩展到免授权频段上进行传输。需要说明的是，在免授权频段，个人、企业、运营商都可以部署无线接入设备，并且部署的位置也比较随意。因此在免授权频段上可能产生较大的干扰，并且干扰情况会经常变化。为了减少免授权频段的干扰对系统性能的影响，通常把高优先级业务，如语音业务等通过授权频段进行传输，把低优先级业务，如FTP(File Transfer Protocol，文件传输协议)下载，网页浏览等通过非授权频段进行传输。然而，当LTE系统采用独立接入(SAA，Standalone Access)的情况，即只有免授权频段可以使用的情况下，必须将高优先级业务通过免授权频段进行传输，当受到WiFi等其它使用免授权频段的无线接入设备干扰时，且由于在非授权频段的数据传输可靠性低，因此，LTE系统的吞吐量(throughput)会下降，时延增加。
针对现有技术中在非授权频段的数据传输可靠性低的问题，目前尚未提出有效的解决方案。

步骤S102：获取通讯设备所属的第一小区的干扰信息。
步骤S104：基于干扰信息确定用于按照多频段传输方式传输数据的频段信息。
步骤S106：将频段信息提供给通讯设备。
采用本申请实施例，基站基于通讯设备所属的第一小区的干扰信息，确定按照多频段传输方式传输数据时使用的频段信息，并将确定的频段信息提供给通讯设备，基站和通讯设备则通过该频段信息完成数据的传输。通过上述实施例，基于通讯设备对应的干扰信息确定可以采用多频段传输方式传输的频段信息，并采用多频段传输方式使用该频段信息将非授权频段的数据发送出来，以保障非授权频段的数据传输的可靠性，从而充分利用非授权频段频率资源丰富的特点，提高了LTE系统的吞吐量，解决了现有技术中在非授权频段的数据传输可靠性低的技术问题。
上述的通讯设备可以为移动通信网络设备，移动通信网络设备可以为移动通信网络终端，该终端是指可以支持陆地移动通信系统的通信协议的终端侧产品，如手机、平板电脑等，也可以是特制通信的调制解调器模块(Wireless Modem)，该调制解调器模块可以被手机、平板电脑、数据卡等各种类型的终端形态集成从而完成通信功能。
具体地，通过用户上报(即移动通讯网络设备上报)，或者通过空口侦听(即基站侦听)的方式，获得移动通讯网络设备所属的第一小区的干扰信息，该干扰信息包括移动通讯网络设备所在的小区 (即本小区)中各个频段受到的干扰强度和/或对本小区产生干扰的干扰源小区使用各个频段的资源使用率，可以根据该干扰信息设计多频段传输方式中的频段信息，基站将该频段信息发送给接收端，即发送给移动通讯网络设备，使基站和移动通讯网络设备通过该频段信息完成数据的传输。
在本申请的上述实施例中，多频段传输方式包括：跳频传输方式和/或并发传输方式。
具体地，通过移动通讯网络设备上报，或者通过基站侦听的方式，可以获得移动通讯网络设备所在的小区(即本小区)中各个频段受到的干扰强度和/或对本小区产生干扰的干扰源小区使用各个频段的资源使用率；基于获得的本小区各个频段受到的干扰强度和/或干扰源小区使用各个频段的资源使用率设计多频段传输方式中的频段信息，即设计跳频传输方式的跳频序列和/或并发传输方式中的合并因子，基站将跳频序列和/或合并因子发送给接收端，即发送给移动通讯网络设备，使基站和移动通讯网络设备通过该频段信息完成数据的传输。
进一步地，基站和移动通讯网络完成数据传输的方式可以包括以下三种：第一种，仅采用跳频序列完成跳频传输的方式，即采用跳频传输方式；第二种，仅采用合并因子进行并发传输的方式，即采用并发传输方式；第三种，结合跳频传输方式和并发传输方式的传输方式。
通过上述实施例，限定了三种数据传输的方式，采用其中的任意一种方式，均可达到将非授权频段的数据发送出来，提高非授权频段的数据传输的可靠性的目的。
在本申请的上述实施例中，在多频段传输方式包括跳频传输方式的情况下，基于干扰信息确定用于按照多频段传输方式传输数据的频段信息包括：基于干扰信息生成用于按照跳频传输方式传输数据的包含跳频序列的频段信息，其中，跳频序列中记录有跳频周期内不同时间段使用的频段。
进一步地，基于干扰信息生成用于按照跳频传输方式传输数据的包含跳频序列的频段信息包括：根据干扰信息中记录的第一小区的各个频段的干扰强度生成跳频序列，其中，跳频序列中的各个频段出现的比例与各个频段的干扰强度具有反比例关系；和/或根据干扰信息中记录的第二小区使用各个频段的资源使用率生成跳频序列，其中，跳频序列中的各个频段出现的比例与各个频段的资源使用率具有反比例关系，其中，第二小区为对第一小区产生干扰的小区，由于对第一小区产生干扰的小区可能是多个，第二小区并不限定于一个产生干扰的小区。
进一步地，根据干扰信息中记录的第一小区的各个频段的干扰强度生成跳频序列，其中，跳频序列中的各个频段出现的比例与各个频段的干扰强度具有反比例关系，即各个频段的干扰强度越大，对应的跳频序列中各个频段出现的比例越小，例如，当第一频段的干扰强度大于第二频段的干扰强度时，在跳频序列中第一频段出现的比例小于第二频段出现的比例；和/或根据干扰信息中记录的第二小区使用各个频段的资源使用率生成跳频序列，其中，跳频序列中的各个频段出现的比例与各个频段的资源使用率具有反比例关系，即各个频段的资源使用率越高，对应的跳频序列中的各个频段出现的比例越小，例如，当第一频段的资源使用率高于第二频段的资源使用率时，在跳频序列中第一频段出现的比例小于第二频段出现的比例，其中，第二小区为对第一小区产生干扰的小区。
上述的第一小区的各个频段的干扰强度可以为移动通讯网络设备所在的本小区中各个频段受到的干扰强度；第二小区使用各个频段的资源使用率可以为对本小区产生干扰的干扰源小区使用各个频段的资源使用率。
具体地，根据本小区中各个频段受到的干扰强度大小和/或干扰源小区使用各个频段的资源使用率，基站随机产生按照跳频传输方式传输数据时使用的跳频序列，产生的跳频序列是周期性的，一个跳频周期内包含有不同时间段使用的频段资源信息。在一个跳频周 期中，不同频段出现的比例与本小区中各个频段受到的干扰强度大小和/或干扰源小区使用各个频段的资源使用率有关。在使用本小区中各个频段受到的干扰强度大小来确定不同频段出现的比例的情况下，对于干扰小的某个频段资源，在跳频周期中出现的比例就大，即该频段的跳频比例大，对于干扰大的某个频段资源，在跳频周期中出现的比例就小，即该频段的跳频比例小；若使用干扰源小区使用各个频段的资源使用率来确定不同频段出现的比例，则在干扰源小区对某个频段的资源使用率高的情况下，该频段在跳频周期中出现的比例小，即该频段的跳频比例相应就小，在干扰源小区对某个频段的资源使用率低的情况下，该频段在跳频周期中出现的比例大，即该频段的跳频比例相应就大。
下面结合图2详述本申请的上述实施例。如图2所示，一个跳频周期内包含的不同时间段使用的频段资源信息包括：{T1，F1}，{T2，F2}，{T3，F3}，{T4，F4}，{T5，F1}，{T6，F3}，{T7，F2}，{T8，F3}，即该实施例中包含了8个时间段和4个频段资源，其中，Ti表示一个跳频周期中的第i个时间段，Fn表示第i个时间段使用的频段，i＝1,2,3,…8，n＝1,2,3,4。
对图2进行分析，假设是根据本小区中各个频段受到的干扰强度大小确定不同频段在跳频周期中出现的比例，如图2所示，F4频段受到的干扰强度最大，在跳频周期中仅出现了一次，跳频比例最小，F3频段受到的干扰强度最小，在跳频周期中出现了三次，跳频比例最大，此外，F1频段和F2频段受到的干扰强度为中，在跳频周期中均出现两次，跳频比例介于F3频段和F4频段之间。
需要说明的是，上述实施例的方案中的跳频周期内可以包含若干个数的不同时间段使用的频段资源信息，若干个数可以为任意个数。
通过上述实施例，可以基于生成的跳频序列，完成基站和移动通讯网络设备之间的跳频传输，从而通过跳频传输方式将非授权频段的数据发送出来，以达到充分利用非授权频段频率资源的目的。
在本申请的上述实施例中，在多频段传输方式包括并发传输方式的情况下，基于干扰信息确定用于按照多频段传输方式传输数据的频段信息包括：基于干扰信息确定用于按照并发传输方式并发传输数据的包含各个频段的合并因子的频段信息。
进一步地，基于干扰信息确定用于按照并发传输方式并发传输数据的包含各个频段的合并因子的频段信息包括：根据干扰信息中记录的第一小区的各个频段的干扰强度确定各个频段的合并因子，其中，各个频段的合并因子与各个频段的干扰强度具有反比例关系；和/或根据干扰信息中记录的第二小区使用各个频段的资源使用率确定各个频段的合并因子，其中，各个频段的合并因子与各个频段的资源使用率具有反比例关系，其中，第二小区为对第一小区产生干扰的小区。
进一步地，根据干扰信息中记录的第一小区的各个频段的干扰强度确定各个频段的合并因子，其中，各个频段的合并因子与各个频段的干扰强度具有反比例关系，即各个频段的干扰强度越大，对应的各个频段的合并因子越小，例如，当第一频段的干扰强度大于第二频段的干扰强度时，第一频段的合并因子小于第二频段的合并因子；和/或根据干扰信息中记录的第二小区使用各个频段的资源使用率确定各个频段的合并因子，其中，各个频段的合并因子与各个频段的资源使用率具有反比例关系，即各个频段的资源使用率越高，对应各个频段的合并因子越小，例如，当第一频段的资源使用率大于第二频段的资源使用率时，第一频段的合并因子小于第二频段的合并因子，其中，第二小区为对第一小区产生干扰的小区。
上述的并发传输是指，在同一时刻，将数据在多个频段上进行并发传输。
具体地，为了将多个频段传输的数据充分合并起来，根据本小区中各个频段受到的干扰强度大小和/或干扰源小区使用各个频段的资源使用率，来确定采用并发传输方式传输数据时，在同一时刻，并发传输数据的各个频段的合并因子。在使用本小区中各个频段受 到的干扰强度大小来确定各个频段的合并因子的情况下，对于干扰小的某个频段资源，对应该频段的合并因子大，对于干扰大的某个频段资源，对应该频段的合并因子小；若使用干扰源小区使用各个频段的资源使用率来确定各个频段的合并因子，则在干扰源小区对某个频段的资源使用率高的情况下，对应该频段的合并因子小，在干扰源小区对某个频段的资源使用率低的情况下，对应该频段的合并因子大。
下面结合图3详述本申请的上述实施例。如图3所示，在T1时刻，将数据放到F1，F2，F3，F4共四个频段上进行并行传输。当用户终端(即移动通讯网络设备)接收到F1频段的数据，F2频段的数据，F3频段的数据，F4频段的数据时，假设根据本小区中各个频段受到的干扰强度大小来确定四个频段对应的合并因子，若F1频段受到的干扰强度最小，则SINR1(Signal to Interference plus Noise Ratio的缩写，即信号与干扰加噪声比)最大，F2频段受到的干扰强度最大，则SINR2最小，F3频段和F4频段受到的干扰强度介于F1频段和F2频段之间，可以为SINR1>SINR2>SINR3>SINR4，即对应的合并因子a1>a2>a3>a4。在用户终端进行数据x的接收合并时，用a1*x+a2*x+a3*x+a4*x获得合并增益。
通过上述实施例，给以信道质量好，干扰强度小的频段更大的加权因子，以保障采用并发传输方式传输数据的传输质量。
在本申请的上述实施例中，基于干扰信息确定用于按照多频段传输方式传输数据的频段信息包括：确定用于传输数据的多个频段，并确定各个频段内用于传输数据的时频资源。
进一步地，确定各个频段内用于传输数据的时频资源包括下述任意一种：获取指示信息中指定的时频资源；在频段内的第一时频资源的信道质量高于第二时频资源的信道质量的情况下，选取第一时频资源作为用于传输数据的时频资源；在频段中随机选取用于传输数据的时频资源。
具体地，在采用跳频传输方式传输数据时，根据本小区中各个 频段受到的干扰强度大小和/或干扰源小区使用各个频段的资源使用率，基站随机产生一个跳频周期内包含的不同时间段使用的频段资源信息。在采用并发传输方式传输数据时，根据本小区中各个频段受到的干扰强度大小和/或干扰源小区使用各个频段的资源使用率来确定在同一时刻，并发传输数据的各个频段的合并因子，并将数据在各个频段上并发传输。
需要说明的是，采用跳频传输方式传输数据，或采用并发传输方式传输数据，或采用两种传输方式的结合传输数据，都可以使用如下任意一种方式确定各个频段内传输数据的时频资源：第一，指示信息中指定的时频资源，即在指示信息中指定的各个频段内的时频资源上传输数据(如图2和图3中所示的，在各个频段的指定时频资源上传输数据)；
第二，在各个频段内的第一时频资源的信道质量高于第二时频资源的信道质量的情况下，选取第一时频资源作为用于传输数据的时频资源。即基站可以根据用户终端反馈的信道质量信息，选择各个频段内信道质量好的时频资源进行传输，选择的各个频段内的时频资源可以相同，也可以不同；(该方案为优选方案之一)
第三，在各个频段中随机选取用于传输数据的时频资源。可以通过设定随机变化公式来实现随机选取，例如，假设A频段有20MHz带宽，共100个RB(Resource Block的缩写，即资源块)，对某用户终端分配的资源为第10个RB至第15个RB。在B频段进行随机变化时，通过产生随机数x，使B频段上的频率资源为第10+x对100取余的RB资源位置至15+x对100取余的RB资源位置。若在跳频传输方式中，通过设定随机变化公式随机选取各个频段传输数据的时频资源时，结合图4进行详细说明，假设F1频段对某用户终端分配的资源为第50个RB至第60个RB，在F2频段进行随机变化，使F2频段对该用户终端分配的资源为第20个RB至第30个RB，同理，使F3频段对该用户终端分配的资源为第70个RB至第80个RB，使F4频段对该用户终端分配的资源为第30个RB至第40个 RB，以实现在不同频段内的跳频传输。在并发传输方式中，通过设定随机变化公式随机选取各个频段传输数据的时频资源的方案类似，在此不再赘述。(该方案为优选方案之二)
通过上述实施例，通过在不同频段内对数据分配具体的时频资源信息，以达到充分利用频率资源选择性的目的。
在本申请的上述实施例中，获取通讯设备所属的第一小区的干扰信息包括：通过侦听器侦听第一小区的干扰信息；和/或获取通讯设备上报的第一小区的干扰信息，其中，干扰信息包括第一小区中各个频段的干扰强度，和/或，对第一小区产生干扰的第二小区使用各个频段的资源使用率。
可选地，通过空口侦听(即基站侦听)或者用户上报(即移动通讯网络设备上报)的方式获得移动通讯网络设备所属的第一小区的干扰信息。具体如下：
空口侦听：LTE基站通常配备Sniffer，可以用来侦听移动通讯网络设备所在的本小区中不同频段受到的干扰强度，并在对某一频段持续侦听一段时间之后，可以获得对本小区产生干扰的干扰源小区使用该频段的资源使用率。
用户上报：用户终端自带接收机，通过接收机接收外界的信号并进行分析可以获得本小区中的多个频段受到的干扰强度以及干扰源小区使用各个频段的资源使用率。
需要说明的是，上述的第一小区中各个频段的干扰强度可以为移动通讯网络设备所在的本小区中各个频段受到的干扰强度；第二小区使用各个频段的资源使用率可以为对本小区产生干扰的干扰源小区使用各个频段的资源使用率，且对本小区产生干扰的干扰源小区可能为一个，也可能为多个，也即第二小区可以是一个，也可以是多个。
可选地，通过CSI-IM(Channel State Information–Interference Measurement)参考信号测量得到干扰强度，或者通过RRM(Radio Resource Measurement)测量得到的RSSI(Received Signal Strength  Indicator)表征干扰强度。

在本申请的上述实施例中，多频段传输方式包括：跳频传输方式和/或并发传输方式。
具体地，通过移动通讯网络设备上报，或者通过基站侦听的方式，可以获得移动通讯网络设备所在的小区(即本小区)中各个频段受到的干扰强度和/或对本小区产生干扰的干扰源小区使用各个频段的资源使用率；基于获得的本小区各个频段受到的干扰强度和/或干扰源小区使用各个频段的资源使用率设计多频段传输方式中的频段信息，即设计跳频传输方式的跳频序列和/或并发传输方式中的合并因子，基站将跳频序列和/或合并因子发送给接收端，即发送给 移动通讯网络设备，使基站和移动通讯网络设备通过该频段信息完成数据的传输。
进一步地，基站和移动通讯网络完成数据传输的方式可以包括以下三种：第一种，仅采用跳频序列完成跳频传输的方式，即采用跳频传输方式；第二种，仅采用合并因子进行并发传输的方式，即采用并发传输方式；第三种，结合跳频传输方式和并发传输方式的传输方式。
通过上述实施例，限定了三种数据传输的方式，采用其中的任意一种方式，均可达到将非授权频段的数据发送出来，提高非授权频段的数据传输的可靠性的目的。
在本申请的上述实施例中，确定单元包括：生成模块，在多频段传输方式包括跳频传输方式的情况下，用于基于干扰信息生成用于按照跳频传输方式传输数据的包含跳频序列的频段信息，其中，跳频序列中记录有跳频周期内不同时间段使用的频段。
进一步地，生成模块包括：第一生成子模块，用于根据干扰信息中记录的第一小区的各个频段的干扰强度生成跳频序列，其中，跳频序列中的各个频段出现的比例与各个频段的干扰强度具有反比例关系；和/或第二生成子模块，用于根据干扰信息中记录的第二小区使用各个频段的资源使用率生成跳频序列，其中，跳频序列中的各个频段出现的比例与各个频段的资源使用率具有反比例关系，其中，第二小区为对第一小区产生干扰的小区，由于对第一小区产生干扰的小区可能是多个，第二小区并不限定于一个产生干扰的小区。
进一步地，根据干扰信息中记录的第一小区的各个频段的干扰强度生成跳频序列，其中，跳频序列中的各个频段出现的比例与各个频段的干扰强度具有反比例关系，即各个频段的干扰强度越大，对应的跳频序列中各个频段出现的比例越小，例如，当第一频段的干扰强度大于第二频段的干扰强度时，在跳频序列中第一频段出现的比例小于第二频段出现的比例；和/或根据干扰信息中记录的第二小区使用各个频段的资源使用率生成跳频序列，其中，跳频序列中 的各个频段出现的比例与各个频段的资源使用率具有反比例关系，即各个频段的资源使用率越高，对应的跳频序列中的各个频段出现的比例越小，例如，当第一频段的资源使用率高于第二频段的资源使用率时，在跳频序列中第一频段出现的比例小于第二频段出现的比例，其中，第二小区为对第一小区产生干扰的小区。
上述的第一小区的各个频段的干扰强度可以为移动通讯网络设备所在的本小区中各个频段受到的干扰强度；第二小区使用各个频段的资源使用率可以为对本小区产生干扰的干扰源小区使用各个频段的资源使用率。
具体地，根据本小区中各个频段受到的干扰强度大小和/或干扰源小区使用各个频段的资源使用率，基站随机产生按照跳频传输方式传输数据时使用的跳频序列，产生的跳频序列是周期性的，一个跳频周期内包含有不同时间段使用的频段资源信息。在一个跳频周期中，不同频段出现的比例与本小区中各个频段受到的干扰强度大小和/或干扰源小区使用各个频段的资源使用率有关。在使用本小区中各个频段受到的干扰强度大小来确定不同频段出现的比例的情况下，对于干扰小的某个频段资源，在跳频周期中出现的比例就大，即该频段的跳频比例大，对于干扰大的某个频段资源，在跳频周期中出现的比例就小，即该频段的跳频比例小；若使用干扰源小区使用各个频段的资源使用率来确定不同频段出现的比例，则在干扰源小区对某个频段的资源使用率高的情况下，该频段在跳频周期中出现的比例小，即该频段的跳频比例相应就小，在干扰源小区对某个频段的资源使用率低的情况下，该频段在跳频周期中出现的比例大，即该频段的跳频比例相应就大。
需要说明的是，上述实施例的方案中的跳频周期内可以包含若干个数的不同时间段使用的频段资源信息，若干个数可以为任意个数。
通过上述实施例，可以基于生成的跳频序列，完成基站和移动通讯网络设备之间的跳频传输，从而通过跳频传输方式将非授权频 段的数据发送出来，以达到充分利用非授权频段频率资源的目的。

进一步地，确定模块包括：第一确定子模块，用于根据干扰信息中记录的第一小区的各个频段的干扰强度确定各个频段的合并因子，其中，各个频段的合并因子与各个频段的干扰强度具有反比例关系；和/或第二确定子模块，用于根据干扰信息中记录的第二小区使用各个频段的资源使用率确定各个频段的合并因子，其中，各个频段的合并因子与各个频段的资源使用率具有反比例关系，其中，第二小区为对第一小区产生干扰的小区。
进一步地，根据干扰信息中记录的第一小区的各个频段的干扰强度确定各个频段的合并因子，其中，各个频段的合并因子与各个频段的干扰强度具有反比例关系，即各个频段的干扰强度越大，对应的各个频段的合并因子越小，例如，当第一频段的干扰强度大于第二频段的干扰强度时，第一频段的合并因子小于第二频段的合并因子；和/或根据干扰信息中记录的第二小区使用各个频段的资源使用率确定各个频段的合并因子，其中，各个频段的合并因子与各个频段的资源使用率具有反比例关系，即各个频段的资源使用率越高，对应各个频段的合并因子越小，例如，当第一频段的资源使用率大于第二频段的资源使用率时，第一频段的合并因子小于第二频段的合并因子，其中，第二小区为对第一小区产生干扰的小区。
上述的并发传输是指，在同一时刻，将数据在多个频段上进行并发传输。
具体地，为了将多个频段传输的数据充分合并起来，根据本小区中各个频段受到的干扰强度大小和/或干扰源小区使用各个频段的资源使用率，来确定采用并发传输方式传输数据时，在同一时刻，并发传输数据的各个频段的合并因子。在使用本小区中各个频段受 到的干扰强度大小来确定各个频段的合并因子的情况下，对于干扰小的某个频段资源，对应该频段的合并因子大，对于干扰大的某个频段资源，对应该频段的合并因子小；若使用干扰源小区使用各个频段的资源使用率来确定各个频段的合并因子，则在干扰源小区对某个频段的资源使用率高的情况下，对应该频段的合并因子小，在干扰源小区对某个频段的资源使用率低的情况下，对应该频段的合并因子大。
通过上述实施例，给以信道质量好，干扰强度小的频段更大的加权因子，以保障采用并发传输方式传输数据的传输质量。

具体地，在采用跳频传输方式传输数据时，根据本小区中各个频段受到的干扰强度大小和/或干扰源小区使用各个频段的资源使用率，基站随机产生一个跳频周期内包含的不同时间段使用的频段资源信息。在采用并发传输方式传输数据时，根据本小区中各个频段受到的干扰强度大小和/或干扰源小区使用各个频段的资源使用率来确定在同一时刻，并发传输数据的各个频段的合并因子，并将数据在各个频段上并发传输。
需要说明的是，采用跳频传输方式传输数据，或采用并发传输方式传输数据，或采用两种传输方式的结合传输数据，都可以使用如下任意一种方式确定各个频段内传输数据的时频资源：第一，指示信息中指定的时频资源，即在指示信息中指定的各个频段内的时频资源上传输数据(如图2和图3中所示的，在各个频段的指定时 频资源上传输数据)；
第二，在各个频段内的第一时频资源的信道质量高于第二时频资源的信道质量的情况下，选取第一时频资源作为用于传输数据的时频资源。即基站可以根据用户终端反馈的信道质量信息，选择各个频段内信道质量好的时频资源进行传输，选择的各个频段内的时频资源可以相同，也可以不同；(该方案为优选方案之一)
第三，在各个频段中随机选取用于传输数据的时频资源。可以通过设定随机变化公式来实现随机选取，例如，假设A频段有20MHz带宽，共100个RB(Resource Block的缩写，即资源块)，对某用户终端分配的资源为第10个RB至第15个RB。在B频段进行随机变化时，通过产生随机数x，使B频段上的频率资源为第10+x对100取余的RB资源位置至15+x对100取余的RB资源位置。若在跳频传输方式中，通过设定随机变化公式随机选取各个频段传输数据的时频资源时，结合图4进行详细说明，假设F1频段对某用户终端分配的资源为第50个RB至第60个RB，在F2频段进行随机变化，使F2频段对该用户终端分配的资源为第20个RB至第30个RB，同理，使F3频段对该用户终端分配的资源为第70个RB至第80个RB，使F4频段对该用户终端分配的资源为第30个RB至第40个RB，以实现在不同频段内的跳频传输。在并发传输方式中，通过设定随机变化公式随机选取各个频段传输数据的时频资源的方案类似，在此不再赘述。(该方案为优选方案之二)
通过上述实施例，通过在不同频段内对数据分配具体的时频资源信息，以达到充分利用频率资源选择性的目的。
