Description

一种通信方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
随着移动通信技术的发展，用户业务量和数据吞吐量不断增加，3G(the 3rd Generation，第三代移动通信***)已不能完全满足用户的求。因此，3GPP(the 3rd Generation Partner Project，第三代合作伙伴计划)致力于研究3GPP LTE(Long Term Evolution，长期演进)作为3G***的演进。
LTE-Advanced是在LTE基础上的技术演进，其支持与LTE***的后向兼容性。在2007年召开的会议上LTE-Advanced已成为一个共享的概念。为了提供更高的数据速率，支持更多的用户业务和新的服务，LTE-Advanced在频点、带宽、峰值速率及兼容性等方面都有新的需求。在从LTE到LTE-Advanced***的演进过程中，更宽频谱的需求将会成为影响演进的重要因素。为此，3GPP提出载波聚合技术作为LTE-Advanced***的关键技术之一。
但是，目前由于受到最大发射功率等因素的限制，在载波聚合时，终端同时只能激活两个载波，除了主载波之外，终端一次只能采用一个辅载波进行上行传输，因此，针对一次传输过程中，在不同的TTI(Transmission Time Interval，传输时间间隔)上，终端只能使用一个辅载波进行传输，这样，存在灵活性较差的缺陷。
如图1A所示，终端激活的是PCC(Primary component carrier，主载波)和SCC(Slave component carrier，辅载波)0，那么在包括多个TTI的传输过程中，终端只在相同的载波上进行上行传输，不会在不同的载波上进行传输。又或者如图1B所示，终端激活的是PCC和SCC1，那么在包括多个TTI的传输过程中，终端只在相同载波上进行上行传输，不会在不同的载波上进行传输。
综上所述，目前的通信过程中，在包括多个TTI的一次传输过程中，终端 只能在相同的载波上进行传输，存在灵活性较差的缺陷。

具体实施方式

下面结合说明书附图对本发明优选的实施方式进行详细说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明，并且在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
参阅图2A所示，本发明实施例中，通信的一种流程如下：
步骤200：基站向终端发送载波配置信息，载波配置信息用于确定终端能够配置的载波；
步骤210：基站采用终端能够配置的载波中的不同载波在不同TTI上进行上行接收。
在该实施例中，步骤200-步骤210中，由于终端在不同的TTI可以采用不同的载波进行传输，进而基站可以采用不同载波在不同的TTI上进行上行接收，这样，在终端能力允许的范围内实现了在不同时刻采用不同载波进行上行传输的效果，解决了灵活性较差的缺陷。
如图2B所示，在TTI0上，采用PCC进行上行接收，在TTI1上，采用SCC0进行上行接收，在TTI2上，采用SCC1进行上行接收，在TTI3上，采用PCC进行上行接收，在TTI4上，采用SCC3进行上行接收，在TTI5上，采用PCC进行上行接收，在TTI6上，采用SCC4进行上行接收，在TTI7上，采用SCC2进行上行接收。
如图2C所示，在这次通信过程中，不同的TTI上可能采用的辅载波不同，例如，在TTI0上，采用SCC3进行上行接收；在TTI1上，采用SCC0进行上行接收；在TTI2上，采用SCC1进行上行接收；在TTI3上，采用SCC2进行上行接收；在TTI4上，采用SCC3进行上行接收；在TTI5上，采用SCC4进行上行接收；在TTI6上，采用SCC4进行上行接收；在TTI7上，采用SCC2进行上行接收，这样，实现了在不同的TTI上可以采用不同的载波进行接收，解决了灵活性较差的缺陷。
本发明实施例中，可选的，终端能够配置的载波的数量大于或者等于终端能够同时采用的载波的数量。
由于终端能够配置的载波的数量大于或者等于终端能够同时采用的载波的数量，也就是说，基站给终端配置载波时，是要参考终端的载波能力，因此，进一步的，基站向终端发送载波配置信息之前，还包括如下操作：
基站接收终端发送的终端的载波能力，载波能力包括终端能够同时采用的载波的数量。
此时，基站向终端发送载波配置信息，可选的，可以采用如下方式：
基站根据终端的载波能力向终端发送载波配置信息。
本发明实施例中，可选的，载波配置信息可以包括终端能够配置的载波中的每一个辅载波进行上行传输的起始TTI及传输周期。
例如，有5个载波：SCC0、SCC1、SCC2、SCC3和PCC，则载波配置信息包括SCC0进行上行传输的起始TTI0和传输周期0、SCC1进行上行传输的起始TTI1和传输周期1、SCC2进行上行传输的起始TTI2和传输周期2、SCC3进行上行传输的起始TTI3和传输周期3、SCC4进行上行传输的起始TTI4和传输周期4，PCC进行上行传输的起始TTI5和传输周期5，如果还有其他载波的话，也同样要确定该载波进行上行传输的起始TTI和传输周期，在此不再进行一一详述。
本发明实施例中，基站在有些情况下需要根据载波上的SRS(Sounding Reference Signal，导频参考信号)进行相关操作，例如，如图2D和图2E所示，基站根据终端在载波上发送的SRS进行加权，从而获得波束赋型，终端将获得较高的接收电平，获得增益，经过外场试验，可以获得大约12％的阵列增益。
又例如，为了减小小区间的干扰，对于SFN(Single Frequency Network，单频网)小区，只有目标RRU(Radio Remote Unit，射频拉远单元)对终端发送信号，不是所有RRU都对终端发送信号，而目标RRU是通过终端发送的SRS进行识别的，如图2F中，RRU1、RR2、RRU3和RRU5均向终端1发送信号的话，会影响其他终端的接收，为了避免干扰，可以选择出终端1的目标RRU为RRU3，同理，可以选择出终端2的目标RRU为RRU4和RRU6，如图2G所示。
但是，目前，终端在有些载波上没有传输SRS，由于基站无法获取该载波的SRS，无法对该载波进行加权，进而也就无法实现波束赋形。
因此，为了使基站能够对使用的每一个载波进行加权，进而实现波束赋形，在基站使用的载波上均可以接收到终端发送的SRS，因此，本发明实施例中，基站采用终端能够配置的载波中的不同载波在不同TTI上进行上行接 收时，可选的，可以采用如下方式：
针对终端能够配置的载波中的每一个载波，基站从与该载波对应的起始TTI开始，采用与该载波对应的传输周期，在该载波上接收终端发送的SRS。
例如，有4个SCC：SCC0、SCC1、SCC2、SCC3，终端在SCC0上进行上行传输的起始TTI和传输周期分别为起始TTI0和传输周期0、终端在SCC1上进行上行传输的起始TTI和传输周期分别为起始TTI1和传输周期1、终端在SCC2上进行上行传输的起始TTI和传输周期分别为起始TTI2和传输周期2、终端在SCC3上进行上行传输的起始TTI和传输周期分别为起始TTI3和传输周期3、终端在SCC4上进行上行传输的起始TTI和传输周期分别为起始TTI4和传输周期4，则针对SCC0，从TTI0开始，采用传输周期0在SCC0上传输SRS，针对SCC1，从TTI1开始，采用传输周期1在SCC1上传输SRS，针对SCC2，从TTI2开始，采用传输周期2在SCC2上传输SRS，针对SCC3，从TTI3开始，采用传输周期3在SCC3上传输SRS。这样，终端在4个SCC上均发送了SRS，针对每一个载波，基站可以根据对应的SRS对该载波进行加权计算，进而实现波束赋形。
本发明实施例中，终端能够配置的载波中对应的起始TTI相同，及对应的传输周期相同的载波的最大数量为终端能够同时采用的载波的数量，也就是说，当终端能够同时采用的载波的数量为3时，最多有3个载波对应的起始TTI和传输周期均相同，例如，载波1对应的起始TTI为TTI1、传输周期为传输周期1，载波2对应的起始TTI也为TTI1、传输周期也为传输周期1，载波3对应的起始TTI也为TTI1、传输周期也为传输周期1，就是说最多可以有3个载波的起始TTI均为TTI1，传输周期均为传输周期1。
当然，上述只是一种保证终端实际同时采用的载波的数量小于或者等于终端能够同时采用的载波的数量，但是并不限定于上述方式，只要每个载波对应的起始TTI和传输周期可以保证同时采用的载波的数量小于或者等于载波能力包括终端能够同时采用的载波的数量即可。
上述讲述的是，如果载波配置信息包括起始TTI及传输周期时，基站是 在目标TTI到达时接收SRS。
例如，SCC0对应的起始TTI为TTI0，传输周期为10ms，则在TTI0采用SCC0接收SRS，在TTI10采用SCC0接收SRS，在TTI20采用SCC0接收SRS，以此类推。
当然，也可以不需要等到目标TTI才发送，而是接收到指令就可以发送。
因此，基站采用终端能够配置的载波中的不同载波在不同传输时间间隔TTI上进行上行接收之前，还包括如下操作：
基站采用不同载波向终端发送SRS发送指令；
此时，基站采用终端能够配置的载波中的不同载波在不同TTI上进行上行接收时，可选的，可以采用如下方式：
基站采用发送SRS发送指令的不同载波在不同TTI上上接收终端根据SRS发送指令发送的SRS。
上述讲述的是采用哪个载波发送SRS发送指令，则采用哪个载波接收SRS，当然，也可以在SRS发送指令携带载波的标识，去与标识对应的载波接收SRS即可。
因此，基站采用终端能够配置的载波中的不同载波在不同传输时间间隔TTI上进行上行接收之前，还包括如下操作：
基站采用不同载波向终端发送SRS发送指令，SRS发送指令携带不同载波分别对应的标识；
此时，基站采用终端能够配置的载波中的不同载波在不同TTI上进行上行接收时，可选的，可以采用如下方式：
基站采用与不同标识分别对应的不同载波在不同TTI上接收终端根据SRS发送指令发送的SRS。
本发明实施例中，可选的，终端能够配置的载波包括基站采用的载波。
本发明实施例中，基站采用终端能够配置的载波中的不同载波在不同传输时间间隔TTI上进行上行接收之后，还包括如下操作：
针对接收到的任意一SRS，基站根据任意一SRS对发送SRS的载波进行 下行载波处理。
其中，进行下行载波处理可以为波束赋形，当然也可以为其他操作，在此不再进行详述。
上述讲述的是基站采用载波接收SRS的过程，当然，在实际应用中，基站也可以利用载波接收上行数据。
当然，基站接收数据，是通过基站调度终端来执行的，因此，本发明实施例中，基站采用终端能够配置的载波中的不同载波在不同TTI上进行上行接收之前，还包括如下操作：
基站向终端发送数据发送指令；
此时，基站采用终端能够配置的载波中的不同载波在不同TTI上进行上行接收时，可选的，可以采用如下方式：
基站采用终端能够配置的载波中的不同载波在不同的TTI上接收终端根据数据发送指令发送的上行数据。
本发明实施例中，为了提高业务质量，基站采用终端能够配置的载波中的不同载波在不同TTI上进行上行接收之后，还包括如下操作：
基站确定在第一TTI上进行上行数据传输的第一载波不满足预设条件，第二载波满足预设条件时，向终端发送载波调整指令。
此时，基站确定在第一TTI上进行上行数据传输的第一载波不满足预设条件时，可选的，可以采用如下方式：
基站确定在第一TTI上进行上行数据传输的第一载波的负载大于负载预设门限值和/或信号质量小于或者等于信号质量预设门限值；
基站确定第二载波满足预设条件时，可选的，可以采用如下方式:
基站确定第二载波的负载小于或者等于负载预设门限值和/或信号质量大于信号质量预设门限值。
上述是从基站侧来描述的通信方法，下面从终端侧来描述通信方法。
参阅图3所示，本发明实施例中，通信的另一种流程如下：
步骤300：终端接收基站发送的载波配置信息；
步骤310：终端根据载波配置信息确定终端能够配置的载波；
步骤320：终端采用能够配置的载波中的不同载波在不同传输时间间隔TTI上进行上行发送。
在该实施例中，步骤300-步骤320中，终端确定能够配置的载波后，在进行上行传输时，在不同的TTI可以采用不同的载波进行传输，这样在终端能力允许的范围内实现了在不同时刻采用不同载波进行上行传输的效果，解决了灵活性较差的缺陷。
如图2B所示，在TTI0上，采用PCC进行上行发送发送，在TTI1上，采用SCC0进行上行发送，在TTI2上，采用SCC1进行上行发送，在TTI3上，采用PCC进行上行发送，在TTI4上，采用SCC3进行上行发送，在TTI5上，采用PCC进行上行发送，在TTI6上，采用SCC4进行上行发送，在TTI7上，采用SCC2进行上行发送。
如图2C所示，在这次通信过程中，不同的TTI上可能采用的辅载波不同，例如，在TTI0上，采用SCC3进行上行发送；在TTI1上，采用SCC0进行上行发送；在TTI2上，采用SCC1进行上行发送；在TTI3上，采用SCC2进行上行发送；在TTI4上，采用SCC3进行上行发送；在TTI5上，采用SCC4进行上行发送；在TTI6上，采用SCC4进行上行发送；在TTI7上，采用SCC2进行上行发送，这样，实现了在不同的TTI上可以采用不同的载波进行发送，解决了灵活性较差的缺陷。
本发明实施例中，可选的，终端能够配置的载波的数量大于或者等于终端能够同时采用的载波的数量。
本发明实施例中，可选的，终端接收基站发送的载波配置信息之前，还包括：
终端向基站发送终端的载波能力，载波能力包括终端能够同时采用的载波的数量。
本发明实施例中，可选的，载波配置信息包括终端能够配置的载波中的每一个载波进行上行传输的起始TTI及传输周期。
例如，有4个辅载波：SCC0、SCC1、SCC2、SCC3，则载波配置信息包括SCC0进行上行传输的起始TTI0和传输周期0、SCC1进行上行传输的起始TTI1和传输周期1、SCC2进行上行传输的起始TTI2和传输周期2、SCC3进行上行传输的起始TTI3和传输周期3、SCC4进行上行传输的起始TTI4和传输周期4，如果还有其他载波的话，也同样要确定该辅载波进行上行传输的起始TTI和传输周期。
本发明实施例中，基站在有些情况下需要根据载波上的SRS进行相关操作，例如，如图2D和图2E所示，基站根据终端在载波上发送的SRS进行加权，从而获得波束赋型，终端将获得较高的接收电平，获得增益，经过外场试验，可以获得大约12％的阵列增益。
又例如，为了减小小区间的干扰，对于SFN小区，只有目标RRU对终端发送信号，不是所有RRU都对终端发送信号，而目标RRU是通过终端发送的SRS进行识别的，如图2F中，RRU1、RR2、RRU3和RRU5均向终端1发送信号的话，会影响其他终端的接收，为了避免干扰，可以选择出终端1的目标RRU为RRU3，同理，可以选择出终端2的目标RRU为RRU4和RRU6，如图2G所示。
但是，目前，由于终端在有些载波上没有传输SRS，由于基站无法获取该载波的SRS，无法对该载波进行加权，进而无法实现波束赋形。
因此，为了使基站能够对每一个载波进行加权，进而实现波束赋形，终端采用能够配置的载波中的不同载波在不同传输时间间隔TTI上进行上行发送时，可选的，可以采用如下方式：
针对终端能够配置的载波中的每一个载波，终端从与该载波对应的起始TTI开始，采用与该载波对应的传输周期，在该载波上发送信道探测参考信号SRS。
例如，有4个SCC：SCC0、SCC1、SCC2、SCC3，终端在SCC0上进行上行传输的起始TTI和传输周期分别为起始TTI0和传输周期0、终端在SCC1上进行上行传输的起始TTI和传输周期分别为起始TTI1和传输周期1、终端在SCC2进行上行传输的起始TTI和传输周期分别为起始TTI2和传输周期2、 终端在SCC3上进行上行传输的起始TTI和传输周期分别为起始TTI3和传输周期3、终端在SCC4上进行上行传输的起始TTI和传输周期分别为起始TTI4和传输周期4，则针对SCC0，从TTI0开始，采用传输周期0在SCC0上传输SRS，针对SCC1，从TTI1开始，采用传输周期1在SCC1上传输SRS，针对SCC2，从TTI2开始，采用传输周期2在SCC2上传输SRS，针对SCC3，从TTI3开始，采用传输周期3在SCC3上传输SRS。
这样，终端在4个SCC上均发送了SRS，基站可以根据每一个载波上的SRS对该载波进行加权，进而实现波束赋形。
本发明实施例中，终端能够配置的载波中对应的起始TTI相同，及对应的传输周期相同的载波的最大数量为终端能够同时采用的载波的数量，也就是说，当终端能够同时采用的载波的数量为3时，最多有3个载波对应的起始TTI和传输周期均相同，例如，载波1对应的起始TTI为TTI1、传输周期为传输周期1，载波2对应的起始TTI也为TTI1、传输周期也为传输周期1，载波3对应的起始TTI也为TTI1、传输周期也为传输周期1，就是说最多可以有3个载波的起始TTI均为TTI1，传输周期均为传输周期1。
当然，上述只是一种保证终端实际同时采用的载波的数量小于或者等于终端能够同时采用的载波的数量，但是并不限定于上述方式，只要每个载波对应的起始TTI和传输周期可以保证同时采用的载波的数量小于或者等于载波能力包括终端能够同时采用的载波的数量即可。
上述讲述的是，如果载波配置信息包括起始TTI及传输周期时，终端是在目标TTI到达时发送SRS。
例如，SCC0对应的起始TTI为TTI0，传输周期为10ms，则在TTI0采用SCC0发送SRS，在TTI10采用SCC0发送SRS，在TTI20采用SCC0发送SRS，以此类推。
当然，也可以是终端接收到SRS发送指令时就发送SRS，而不需要等到目标TTI才发送。
因此，本发明实施例中，终端采用能够配置的载波中的不同载波在不同 传输时间间隔TTI上进行上行发送之前，还包括如下操作：
终端接收基站采用不同载波发送的SRS发送指令；
此时，终端采用能够配置的载波中的不同载波在不同传输时间间隔TTI上进行上行发送时，可选的，可以采用如下方式：
终端采用接收SRS发送指令的不同载波在不同TTI上发送SRS。
上述讲述的是采用哪个载波接收到SRS发送指令，则采用哪个载波发送SRS，当然，也可以在SRS发送指令携带载波的标识，去与标识对应的载波发送SRS即可。因此，本发明实施例中，终端采用能够配置的载波中的不同载波在不同传输时间间隔TTI上进行上行发送之前，还包括如下操作：
终端接收基站采用不同载波发送的SRS发送指令，、SRS发送指令携带不同载波分别对应的标识；
此时，终端采用能够配置的载波中的不同载波在不同传输时间间隔TTI上进行上行发送时，可选的，可以采用如下方式：
终端采用不同标识分别对应的不同载波在不同TTI上发送SRS。
本发明实施例中，可选的，终端能够配置的载波包括基站采用的载波。
上述讲述的是终端利用载波发送SRS的情况，当然，在实际应用中，终端也可以利用载波发送上行数据。
但是，终端到底要发送SRS还是要发送上行数据，都是基站来调度的，因此，终端采用能够配置的载波中的不同载波在不同传输时间间隔TTI上进行上行发送之前，还包括如下操作：
终端接收基站发送的数据发送指令；
此时，终端采用能够配置的载波中的不同载波在不同传输时间间隔TTI上进行上行发送时，可选的，可以采用如下方式：
终端根据述数据发送指令采用能够配置的载波中的不同载波在不同传输时间间隔TTI上发送上行数据。
进一步的，终端采用能够配置的载波中的不同载波在不同传输时间间隔TTI上进行上行发送之后，还包括如下操作：
终端接收载波调整指令；
终端根据载波调整指令，将采用第一载波在第一TTI上传输的上行数据，调整至采用第二载波在第二TTI上进行传输。
此处需要说明的是，将采用第一载波在第一TTI上传输的上行数据，调整至采用第二载波在第二TTI上进行传输时，在具体实现时，要将第一载波对应的发射通道关闭，将第二载波对应的发射通道打开。
