为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
鉴于异系统共存的场景下，两种不同(例如GSM，UMTS)系统的频谱间保护带宽不够，第一制式系统(例如GSM)信号会对第二制式系统(例如UMTS)造成较大的干扰，本申请实施例提供一种异制式系统间协调发射信号的方法及装置，基于终端的接收机能够抑制系统内的干扰，通过在第一制式系统的可重构时隙上发射具有第二制式系统的信号模式的构造信号，使得终端能够抑制构造信号对第二制式系统的发射信号的干扰，从而减少了第一制式系统的发射信号对第二制式系统的干扰。
本申请实施例涉及的第一制式网络和第二制式网络分别可以是：第二代移动通信技术(即2G)，第二代移动通信技术(即3G)系统和下一代通信系统，例如全球移动通信系统(GSM，Global System for Mobile communications)，码分多址(CDMA，Code Division Multiple Access)系统，时分多址(TDMA，Time Division Multiple Access)系统，宽带码分多址(WCDMA，Wideband Code Division Multiple Access Wireless)，频分多址(FDMA，Frequency Division Multiple Addressing)系统，正交频分多址(OFDMA，Orthogonal Frequency-Division Multiple Access)系统，单载波FDMA(SC-FDMA)系统，通用分组无线业务(GPRS，General Packet Radio Service)系统，长期演进(LTE，Long Term Evolution)系统，第五代移动通信技术(即5G)系统，以及其他此类通信系统。
本申请实施例应用的系统架构如图1所示，包括基站101和终端102。本文中结合终端和/或基站和/或基站控制器来描述各种方面。
基站101(例如，接入点)可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站101可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。基站101还可协调对空中接口的属性管理。基站101可以对发射信号进行编码调制和发送。基站101可以是多模基站，能够支持至少两种不同制式的业务运行。
终端102，可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和数据连通性的设备，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(Radio Access Network，RAN)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数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字 助理(Personal Digital Assistant，PDA)等设备。无线终端也可以称为系统、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)、或用户装备(User Equipment)。
一方面，为了提升针对系统内或者满足特定条件特征的干扰抑制能力，接收机会设计一些干扰消除和干扰抑制算法，比如对于UMTS系统，典型的终端都支持Type3i接收机，能够消除UMTS邻区的下行干扰。
另一方面，由于各种不同的原因，一些系统存在一些特殊开销的时隙，在该特殊开销的时隙上发送一些不需要终端解调译码的信号。比如GSM系统需要在主广播控制信道(Broadcast Control Channel，BCCH)上连续不断的发送信号，当GSM系统没有任何具体消息要发送时，就会发送空闲突发脉冲(即Dummy Burst)，发送空闲突发脉冲的时隙可称为虚设时隙(即Dummy时隙)。GSM系统基站在Dummy时隙发送功率，是为了保证终端能够测量下行功率，以保证GSM切换性能。
基于此，本申请实施例中，将不同系统之间联合调制发射信号，在一些系统的特殊时隙，构造另一个系统的发射信号，使得终端能够执行系统内干扰抑制，从而减弱了特殊时隙发射信号的系统间干扰。
下面将结合附图对本申请实施例提供的异制式系统间协调发射信号的方法及装置作详细说明。
基于图1所示的系统架构，参参阅图2所示，本申请实施例提供的异制式系统间协调发射信号的方法流程如下所述。
步骤201、基站确定第一制式系统中的可重构时隙。
其中，基站在可重构时隙上发送的信号，终端对在可重构时隙上接收的信号不执行解调译码；基站在可重构时隙上发送的信号可用于终端进行切换测量。
步骤202、基站预生成具有第二制式系统的信号模式的第一发射信号，并将第一发射信号处理成具有第一制式系统的信号模式的第二发射信号。
其中，第一制式系统的信号模式和所述第二制式系统的信号模式均包括：时域特征、频域特征和功率特征。例如，载频带宽与具体的网络制式相关，若第一制式系统为GSM系统，则其载频带宽为200Khz，若第二制式系统为UMTS系统，则其载频带宽为5Mhz。
具体地，基站预生成具有第二制式系统的信号模式的导频信号；将导频信号进行滤波处理以及功率调整，生成与第一制式系统的信号具有相同载频带宽、相同发射功率的构造信号。
步骤203、基站在可重构时隙上发送第二发射信号。
具体地，基站可以在第一制式系统下的可重构时隙上发送第二发射信号；也可以，基站在保证第一制式系统与第二制式系统时间同步的基础上，在第一制式系统下的可重构时隙上保持静默，且在第二制式系统下与可重构时隙对齐的时隙上发送第二发射信号。
基站在可重构时隙上发送第二发射信号后，终端接收基站在可重构时隙上发送的第二发射信号。
由于第二发射信号已被处理成具有第一制式系统的信号模式的信号，因此，终端在接收到第二发射信号后，不仅能够应用第一制式系统的可重构时隙上的接收信号的功能，并 且，还可以通过系统内信号的干扰消除机制消除第二发射信号对第二制式系统信号的干扰。
需要说明的是，上述基站为多模基站，可选的，本申请提供的方法也可以应用于不同制式系统的基站不同的情况，即第一制式系统中的第一基站和第二制式系统中的第二基站分别用于执行上述方法中涉及的基站(即多模基站)中在第一制式系统内和第二制式系统内的操作。
下面结合具体的应用场景对图2所示的方法进行说明。
例如，第一制式系统为GSM系统，第二制式系统为UMTS系统，GSM系统的可重构时隙为Dummy时隙。则应用上述图2所示的方法的主要思想就是，在GSM系统的Dummy时隙上构造GSM信号并发射，终端可以消除GSM系统的Dummy时隙发射的信号对UMTS系统信号的干扰，同时，由于构造信号与GSM系统的功率、带宽一致，终端还是能够根据Dummy时隙上接收的构造信号进行切换测量。
如图3所示，基站可以在内部支持GSM系统和UMTS系统两种制式网络业务的运行。在UMTS侧，基站将待发送的UMTS数据流进行编码调制，然后进行射频处理后，通过天线发送。在GSM侧，基站在有GSM数据流要发送时，在GSM数据时隙对GSM数据进行编码调制，后经过射频处理，经过天线发送。在没有GSM数据流要发送时，会在Dummy时隙发送空闲突发脉冲，这里，在Dummy时隙重构一种发射信号，后经过射频处理，经过天线发送。具体地，通过基带生成载频带宽为5Mhz的UMTS辅导频信号(当然，还可以为其他类型的信号)，将生成的UMTS辅导频信号进行调制、加扰处理，在基带侧对调制、加扰处理后的UMTS辅导频信号进行数字域滤波处理，生成载频带宽为200Khz的UMTS辅导频信号，将载频带宽为200Khz的UMTS辅导频信号的功率调整为与GSM在Dummy时隙发送空闲突发脉冲相同的功率。这样，就模拟构造了一种类似GSM在Dummy时隙发送空闲突发脉冲的UMTS信号，可简称为构造信号。构造信号和UMTS信号在空口混合后被终端接收，由于基站在GSM的Dummy时隙发送的构造信号具有UMTS信号的信号模式，因此，终端可以通过系统内干扰消除的算法来消除构造信号对UMTS信号的干扰。
除上述图3所示的GSM系统和UMTS系统两种制式网络联合调制发射信号的方式之外，如图4所示，上述构造信号可以在UMTS侧生成。具体地，在GSM侧，基站在有GSM数据流要发送时，在GSM数据时隙对GSM数据进行编码调制，后经过射频处理，经过天线发送。在没有GSM数据流要发送时，会在Dummy时隙保持静默。在UMTS侧，基站将待发送的UMTS数据流进行编码调制，然后进行射频处理后，通过天线发送；另外，基站调整UMTS系统和GSM系统保持时间同步的基础上，在GSM的Dummy时隙重构一种发射信号，即上述构造信号，具体构造过程如图3所示相同，在此不再赘述。这样，终端在接收到基站在GSM系统发射的构造信号后，依旧可以根据构造信号进行GSM系统的切换测量，且还可以通过系统内干扰消除的算法来消除构造信号对UMTS信号的干扰。

可选的，还包括同步单元504，用于在发送单元503在第二制式系统下与可重构时隙对齐的时隙上发送第二发射信号之前，将第一制式系统与第二制式系统进行时间同步。
