本发明实施例涉及无线通信领域，尤其涉及上行信道发送方法和装置。
背景技术
在无线通信领域中，终端通过上行信道向基站发送上行数据，为了基站能够解调终端发送的上行数据，终端在上行信道所在的时域资源中发送该上行信道的参考信号(Reference Signal，RS)，一个参考信号在时间上为一个符号，例如解调参考信号(Demodulation Reference Signal，DMRS)，以便基站利用接收的RS进行信道估计，并根据信道估计的结果，解调该上行信道。
在目前的通信系统中，对于每个传输时间间隔(transmission time interval，TTI)发送的上行信道，上行功率控制是在时域资源上有该上行信道的RS的情况下进行的。然而随着通信技术的演进，TTI可能会不断缩短，如果每个TTI仍保持至少一个RS，那么RS占用的总符号数就会增加，系统的开销也随着增加，从而导致系统资源的使用效率下降，如果为例减少系统开销而减少RS占用的符号，现有的上行功率控制会不适应这种情况。

可见，在以上各个方面，对于待发送的上行信道，终端根据该上行信道所在的时域资源上是否包括上行信道的RS，分别进行功率控制，可以适应时域资源缩短对RS开销减少的需求。另外，基站可以预先判断并指示终端是否发送上行信道的RS，以适应时域资源缩短对RS开销减少的需求。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
以下，对本发明中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、终端，又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
2)、基站，又称为无线接入网(Radio Access Network，RAN)设备是一种将终端接入到无线网络的设备，包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)。此外，还可以包括Wifi接入点(Access Point， AP)等。
3)、“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
4)、时域资源：信道的传输时间单位，例如可以为TTI，在此，长度小于1ms的TTI称为短TTI，例如小于或等于0.5ms的TTI。长度等于1ms的TTI称为常规TTI。不同时域资源的长度可能相同也可能不相同，例如第一时域资源为短TTI，第二时域资源为常规TTI。以下具有第X时间长度的第X时域资源中的时域资源即为该含义。其中X为正整数。短TTI的时间长度小于1个子帧或1ms，如0.5ms、7个符号长度、6个符号长度、5个符号长度、4个符号长度、3个符号长度、2个符号长度或1个符号长度。在LTE的系统里，各种物理信道可以在一定时间长度的传输时间段内进行传输，进一步，物理信道可以是在传输时间段内的全部或部分的时频域资源上传输。
5)、符号：OFDM符号或SC-FDMA符号。符号是15kHz子载波间隔的LTE系统的正交频分复用多址OFDMA符号、单载波频分多址SC-FDMA符号，或者是更大子载波占用频率的通信系统的符号，本实施例对此不作限定。
请参考图1，其为本发明实施例提供的一种通信系统的示意图。 如图1所示，该通信系统包括基站110，终端120通过基站110接入无线网络，以通过无线网络获取外网(例如因特网)的服务，或者通过无线网络与其它终端通信。在下行方向上，当基站110有数据发送给终端120时，通过下行信道向终端120发送该数据；在上行方向上，当终端120有数据发送时，通过上行信道将数据发送给基站110。这里的上行信道可以包括上行控制信道，例如物理上行控制信道(physical uplink control channel，PUCCH)或短PUCCH(short PUCCH，sPUCCH)，还可以包括上行数据信道，例如物理上行共享信道(physical uplink shared channel，PUSCH)或短PUSCH(sPUSCH)。其中PUCCH或sPUCCH用于承载控制信息，PUSCH或sPUSCH用于承载业务数据，当然，也可以将控制信息承载于PUSCH或sPUSCH上，本申请对信道承载的内容不作任何限制。其中，sPUCCH为小于1ms(例如小于或等于0.5ms)的时域资源上的控制信道，即sPUCCH为用于承载小于1ms的时域资源上的上行控制信息的信道。sPUSCH为小于1ms(例如小于或等于0.5ms)的时域资源上的数据信道，即sPUSCH为用于承载小于1ms的时域资源上的上行数据信息和/或上行控制信息的信道。
目前，终端发送上行信道的功率控制过程一般包括：终端准备上行信道需承载的数据或上行控制信息，然后根据路径损耗计算终端当前TTI的所有上行信道的需求发射功率，如果所有上行信道的需求发射功率之和超过了终端允许的最大发射功率，那么终端按照信道类型的优先级或者携带上行控制信息的优先级，对全部或部分上行信道的 功率进行压缩，具体为优先为高优先级的信道分配功率，再为低优先级的信道分配功率，如果信道的优先级相同就做等比例减少发送功率，以保证所有上行信道的发射功率之和不超过终端允许的最大发射功率。之后，使用按照优先级分配的发射功率发送全部或部分上行信道。可以理解的是，当所有上行信道的需求发射功率之和超过终端允许的最大发射功率，那么优先级低的上行信道可能没有被分配到功率，或者分配的功率为零，最终不会被发送。
在以上上行信道发送过程中，为了基站能够解调上行信道，在上行信道所在的时域资源上发送该上行信道的RS。基站利用接收的RS进行信道估计，再利用信道估计结果，解调上行信道。
目前，在长期演进(Long Term Evolution，LTE)系统中，终端的时域资源为TTI，TTI的长度为1ms。且对于每个时域资源上发送的上行信道，该时域资源上都有该上行信道的RS，基站利用RS解调该上行信道。然而随着通信技术的发展，时域资源会减小，例如小于或等于0.5ms。如果对于每个发送上行信道，在时域资源内都发送RS，则RS开销比较大，影响了系统资源的使用效率。因此，希望降低RS的开销，但为了降低RS开销，就会出现在不同时域资源上的上行信道的RS为同一个RS的情况。基站利用终端在之前的时域资源上传输的RS，解调当前传输资源上的上行信道时，如果终端的上行功率控制不合适，就会出现基站无法解调或解调错误的情况。
有鉴于此，本发明实施例提供一种上行信道的发送方法，对于待发送的上行信道，根据该上行信道所在的时域资源上是否包括该上行 信道的RS，来分别进行不同的功率控制方法，以适应时域资源缩短对RS开销减少的需求的同时保证基站可以正确接收该上行信道。其中，对于多个时域资源上的上行信道的RS为同一个RS的情况，也就是待发送上行信道所在的时域资源上不包括该上行信道的RS的情况，终端使用之前的时域资源上至少一个上行信道的发射功率之和作为功率分配的前提，以减少因当前时域资源的上行信道与该上行信道的RS的相位不同引发的基站无法正确解调该上行信道的情况，提高了基站解调上行信道的正确率。
请参考图2，其为本发明实施例提供的上行信道发送方法的示意图。如图2所示，终端在第一时域资源内发送第一上行信道，在此之前，终端在第二时域资源内发送第二上行信道。其中第一时域资源为t1时刻到t2时刻，第二时域资源为t0时刻到t1时刻，第一时域资源的时间长度和第二时域资源的时间长度可以相等，也可以不等。亦即，终端以第一发射功率在第一时域资源向基站发送第一上行信道，第一时域资源的时间长度为t2-t1，即第一时间长度等于t2-t1；在第一时域资源之前的第二时域资源上，终端以第二发射功率向基站发送第二上行信道，第二时域资源的时间长度为t1-t0，即第二时间长度等于t1-t0。其中，第一时域资源上不包括第一上行信道的RS，而第二时域资源上包括该第一上行信道的RS，即基站解调第一上行信道是利用该第二时域资源上的RS来实现，当然该RS也可以被基站用来解调第二上行信道，也就是第一上行信道的RS和第二上行信道的RS可以是同一个RS，因此该RS也可以称为第二上行信道 的RS。即，第n信道的RS为用于解调该第n信道的RS，其可以位于该第n信道所在的时域资源上，也可以位于其它时域资源上，其中n为正整数。
需要说明的，在第一上行信道和第二上行信道是相同的信道类型时，例如都是上行控制信道或上行数据信道，那么第一上行信道和第二上行信道的RS可以是同一个RS。否则，第一上行信道和第二上行信道的RS是不同的RS。
可选的，当第二上行信道与第一上行信道具有相同的信道类型时，占用相同的频域资源，使用相同的调制编码方式。
由于第一上行信道所在的第一时域资源上不包括该第一上行信道的RS，则终端在确定该第一上行信道的发射功率时满足以下条件，以减少因当前时域资源的上行信道与该上行信道的RS的相位不同引发的当前时域资源的上行信道解调失败的问题：
第一发射功率小于或等于第一发射总功率，且第一时域资源上的至少一个上行信道的发射功率之和等于该第一发射总功率，其中，该第一发射总功率为第二时域资源上的至少一个上行信道的发射功率之和。
此外，在进行功率分配时，第一时域资源上所有信道的总功率小于第一时域资源的终端允许的最大发射功率和第二时域资源上所有信道的总功率小于第二时域资源的终端允许的最大发射功率，如图2所示，分别为第一阈值功率和第二阈值功率。由于这部分为本领域技术人员所知悉，在此不再详述。
以上以第二时域资源上的第二上行信道包括RS为例进行说明，当然，第二时域资源上的第二上行信道可以不包括RS，但依然使用前面的条件进行功控分配。
以上以第一时域资源和第二时域资源上只发送一个上行信道为例进行说明，当然，第一时域资源上和第二时域资源上可以发送多于一个上行信道。当第一时域资源上和第二时域资源上发送多于一个上行信道时，以上第一上行信道是第一时域资源上的至少一个上行信道中的一个信道，以上第二上行信道是第二时域资源上的至少一个上行信道中的一个信道，则第一时域资源上的至少一个上行信道的发射功率之和与第二时域资源上的至少一个上行信道的发射功率之和相等。这里的第一时域资源上的至少一个上行信道和第二时域资源上的至少一个上行信道对应于同一个功率放大器(power amplifier，PA)，或，同一个载波或载波组，该同一个载波或载波组对应于同一个PA。即，第一时域资源上和第二时域资源上对应于同一个PA的上行信道的发射功率之和相等，或者第一时域资源上和第二时域资源上对应于同一个载波或载波组的上行信道的发射功率之和相等。
假设第一时域资源上对应于第一PA的上行信道为M个，第二时域资源上对应于第一PA的上行信道为N个，则以上条件为M个上行信道的发射功率之和与N个上行信道的功率之和相等；同样的，假设第一时域资源上对应于第一载波(或载波组)的上行信道为M个，第二时域资源上对应于第一载波(或载波组)的 上行信道为N个，则以上条件为M个上行信道的发射功率之和与N个上行信道的功率之和相等。其中，M和N为大于或等于1的正整数，且M和N可以相等，也可以不相等。
需要说明的是，以上第一时域资源和第二时域资源为相邻的时域资源，然而这仅用于举例，第一时域资源和第二时域资源也可以不相邻，也就是说，第一时域资源和第二时域资源之间可能还相隔至少一个时域资源，这些时域资源内的时域资源上也不包括第一上行信道的RS。
此外，以上第一时域资源和第二时域资源可以是相同的时域资源，也可以是不同的时域资源，且可以是常规TTI，也可以是短TTI。
可见，本申请实施例中，终端在多个时域资源向基站发送多个上行信道时，为了基站可以利用同一个RS解调多个上行信道，终端在多个时域资源上的至少一个上行信道的发射功率之和相等，其中所述的至少一个上行信道可以对应于同一个载波或者同一个载波组或者对应于同一个PA。所述同一个载波或载波组可以为对应同一个PA的载波或载波组。
请参考图3，其为本发明实施例提供的一种上行信道发送方法的流程图，如图3所示，所述方法包括以下步骤：
S301：终端确定第一上行信道的第一发射功率，其中，第一上行信道是在具有第一时间长度的第一时域资源上的至少一个上行信道中的一个信道。
其中，当第一时域资源上包括第一上行信道的RS时，终端根据路损值确定第一发射功率；当第一时域资源上不包括第一上行信道的RS时，第一发射功率小于或等于第一发射总功率，且第一时域资源上的至少一个上行信道的发射功率之和等于该第一发射总功率，其中，该第一发射总功率为具有第二时间长度的第二时域资源上的至少一个上行信道的发射功率之和，且第一时域资源的起始时刻在第二时域资源的起始时刻之后。
S302：终端以第一发射功率发送第一上行信道。
可选的，如果起始时刻在第一时域资源的最后一个符号，那这个上行信道的功率可以不计算在第一发射总功率。
可选的，当第一时域资源上包括第一上行信道的RS时，终端根据路损值确定第一发射功率具体包括：终端根据路损值、本载波的配置UE发射功率、功控命令字等信息确定第一发射功率。由于这部分为本领域技术人员所知悉，在此不再详述。
可选的，当第一时域资源上不包括第一上行信道的RS时，终端根据第一发射总功率，确定第一发射功率。示例性的，当第一时域资源上只有第一上行信道时，那么第一发射功率等于第一发射总功率；当第一时域资源上除第一上行信道还存在P个上行信道，且P个上行信道中有Q个上行信道与第一上行信道在同一个载波或载波组，或对应着同一个PA时，那么第一发射功率与Q个上行信道的发射功率的之和等于第一发射总功率，终端根据第一上行信道与P个上行信道的优先级，为第一上行 信道和P个上行信道分配发射功率，使得第一发射功率与Q个上行信道的发射功率的之和等于第一发射总功率，P大于或等于Q，P和Q是大于等于0的整数。
可选的，终端可以先使用现有技术相同的方法，根据路损值等信息，确定第一信道的第一上行信道的需求功率；然后，基站再根据第一上行信道的需求功率和第一发射总功率，确定第一信道最终使用的第一发射功率。示例性的，当终端根据第一上行信道与Q个上行信道的第一上行信道的需求功率大于第一发射总功率时，终端根据第一上行信道与Q个上行信道的优先级，为第一上行信道和Q个上行信道分配发射功率，使得第一发射功率与Q个上行信道的发射功率的之和等于第一发射总功率。当终端根据第一上行信道与Q个上行信道的第一上行信道的需求功率小于第一发射总功率时，终端为第一上行信道与Q个上行信道中的至少一个信道分配大于该至少一个信道的第一上行信道的需求功率，以使得得第一发射功率与Q个上行信道的发射功率的之和等于第一发射总功率；当终端根据第一上行信道与Q个上行信道的第一上行信道的需求功率等于第一发射总功率时，所述终端为第一上行信道与Q个上行信道，分配其的需求的第一发射功率。
可选的，终端根据路损值等信息和第一发射总功率，确定第一信道的第一上行信道的需求功率；然后，基站再根据第一上行信道的需求功率和第一发射总功率，确定第一信道最终使 用的第一发射功率。示例性的，第一上行信道的需求功率＝{第一发射总功率，第一子需求发射功率}取较大值，其中，第一子需求发射功率是根据现有技术计算出来的需求的发射功率值，这里不再赘述。然后，当终端根据第一上行信道与Q个上行信道的第一上行信道的需求功率大于第一发射总功率时，终端根据第一上行信道与P个上行信道的优先级，为第一上行信道和Q个上行信道分配发射功率，使得第一发射功率与Q个上行信道的发射功率的之和等于第一发射总功率；当终端根据第一上行信道与Q个上行信道的第一上行信道的需求功率等于第一发射总功率时，所述终端为第一上行信道与Q个上行信道，分配其的需求的第一发射功率。
需要说明的，以上P个上行信道所在的时域资源可以是第一上行信道所在的第一时域资源，也可以是和第一上行信道所在的第一时域资源重叠的其他时域资源，P个上行信道的时域资源的时间长度与第一时域资源的第一时间长度可以相同，也可以不同。这里不做限定。
以上方法适用于短TTI传输时，可以有效减少RS的开销，同时提高基站解调上行信道的正确率。此时，第一时间长度小于或等于0.5ms。对于第二时间长度不做限制，可以为常规TTI，即1ms，也可以为短TTI，例如小于或等于0.5ms。
可选的，以上第二时域资源上可以包括该第一上行信道的RS，则第一上行信道的解调便可以利用该第二时域资源上的RS 实现。或者，第二时域资源上不包括第一上行信道的RS，第一上行信道的解调利用第二时域资源之前的时域资源上的RS进行。对于第二时域资源上的这个上行信道的功率分配同第一上行信道的功率分配，需要考虑之前的时域资源上至少一个上行信道的发射总功率，在此不再赘述。
需要说明的是，当第二时域资源上仅发送一个上行信道时，第一发射总功率即为该一个上行信道的发射功率。且当第一时域资源上仅发送一个上行信道，即第一上行信道时，第一时域资源上的至少一个上行信道的发射功率之和即为该第一上行信道的发射功率，此时，第一上行信道的发射功率等于第二时域资源上的该一个上行信道的发射功率。此外，对于终端的某个PA，当第二时域资源上仅发送一个对应于该PA的上行信道时，第一发射总功率即为该一个上行信道的发射功率。且当第一时域资源上仅发送一个对应于该PA的上行信道，即第一上行信道时，第一时域资源上的至少一个上行信道的发射功率之和即为该第一上行信道的发射功率，此时，第一上行信道的发射功率等于第二时域资源上的上行信道的发射功率。对于同一个载波或载波组的情况与之类似，在此不再赘述。
请继续参考图4，其为本发明实施例提供的另一种上行信道发送方法的流程图。如图4所示，该方法由终端执行，包括：
S401：确定第一时域资源内终端允许的最大发射功率是否大于或等于第一发射总功率；
S402：当第一时域资源内终端允许的最大发射功率大于或等于第一发射总功率时，以第一发射功率发送第一上行信道，且第一时域资源上不包括该第一上行信道的RS。此时第一发射功率满足图3所示实施例的中第一时域资源上不包括第一上行信道的RS时对第一发射功率的要求。
S403：当第一时域资源内终端允许的最大发射功率小于第一发射总功率时，放弃第一上行信道的发送或者在第一时域资源上发送该第一上行信道的RS。
在以上方法中，终端在分配功率之前，先进行判断第一时域资源内终端允许的最大发射功率是否小于，或大于，或等于第一发射总功率，如果小于第一发射总功率，说明无论终端怎么分配功率，也没办法达到使得当前第一时域资源上的至少一个上行信道的发射功率之和等于第一发射总功率，因此如果仍只发送第一上行信道，则基站会因为第一上行信道和第一上行信道的RS相位不同导致无法解调第一上行信道，因此可以放弃发送第一上行信道，这样就避免了终端发送了上行信道而基站又无法解调，造成终端功率的浪费；也可以在第一时域资源上发送该第一上行信道的RS，这样就可使得基站能够根据第一时域资源上发送该第一上行信道的RS，去解调该第一上行信道。
请继续参考图5，以上步骤S401可以利用以下步骤S501取代，图5中的其它步骤与图4中的其它步骤类似，在此不再赘述。
S501：确定第一时域资源内终端允许的最大发射功率大于或等于第二时域资源内终端允许的最大发射功率；
S502：当第一时域资源内终端允许的最大发射功率大于或等于第二时域资源内终端允许的最大发射功率时，以第一发射功率发送第一上行信道，且第一时域资源上不包括该第一上行信道的RS。此时第一发射功率满足图3所示实施例的中第一时域资源上不包括第一上行信道的RS时对第一发射功率的要求。
S503：当第一时域资源内终端允许的最大发射功率小于第二时域资源内终端允许的最大发射功率时，放弃第一上行信道的发送或者在第一时域资源上发送该第一上行信道的RS。
之所以可以利用步骤S501取代步骤S401，是因为第一发射总功率小于或等于第二时域资源内终端允许的最大发射功率，如果第二时域资源内终端允许的最大发射功率小于第一时域资源内终端允许的最大发射功率，那么第一发射总功率就小于或等于第一时域资源内终端允许的最大发射功率，即第一时域资源内终端允许的最大发射功率大于或等于第一发射总功率。因此，满足该步骤S501的条件，即可以满足步骤S401的条件，因此可以利用步骤S501取代步骤S401。
可选的，可以通过预定义的方式使得第一时域资源内终端允许的最大发射功率等于第二时域资源内终端允许的最大发射功率相等，这样也可以确保以上步骤S401和S501的条件满足。因此，在一实施例中，终端可以配置第一时域资源内终端允许 的最大发射功率等于第二时域资源内终端允许的最大发射功率。这样终端可以不需要再执行以下步骤S401和S501，而直接进行步骤S402和S502中以第一发射功率发送第一上行信道的步骤，且第一时域资源上不包括该第一上行信道的RS。
在一种实现方式中，可以设置多个时域资源上终端允许的最大发射功率为同一个共用功率阈值，该共用功率阈值为这些时域资源上的功率阈值中的最小功率阈值，即该共用功率阈值＝min{第一功率阈值，…，第k功率阈值}，其中k为大于1的正整数，其中第k功率阈值为终端在第k个时域资源上终端允许的最大发射功率。终端可以根据基站发送的调度信息确定该第k功率阈值。
示例性的，终端根据第k个时域资源所在的载频E-UTRA Band，信道带宽(channel bandwidth),以及基站发送的调度信息指示的资源块(resource block)，确定第k功率阈值的下限值。终端根据基站配置的最大上限值和终端的功率等级，确定第k功率阈值的上限值。终端在上限值和下限值之间，选择一个值作为第k功率阈值。
在另一种实现方式中，可以设置k个时域资源上终端允许的最大发射功率为同一个共用功率阈值，该共用功率阈值为发送起始时刻最早的一个时域资源，或者该共用功率阈值为发送起始时刻前j个时域资源上的功率阈值中的最小功率阈值，即该共用功率阈值＝min{第一功率阈值，…，第j功率阈值}，其中 j为大于1的正整数且小于或等于k，其中第j功率阈值为终端在第j个时域资源上终端允许的最大发射功率。确定第j个功率阈值和前一个实现方式相同，这里不再赘述。
请参考图6A，其为本发明实施例提供的一种上行信道的传输重叠场景的示意图,如图6A所示，上行信道610和620所在的时间长度相同。所述的上行信道610和620所在的时间长度可以不相同，如图6B所示。上行信道610和620在传输时间上存在重叠区域ST，如图6A或者6B所示，则上行信道610和620的传输存在重叠，该重叠可以是部分重叠也可以使全部重叠，在此以部分重叠为例。终端在为上行信道610和620分配功率时需要考虑重叠区域所在时间上，这两个上行信道的功率之和需要满足以上实施例中的功率要求，为了满足这个要求，可能需要对这两个上行信道的功率进行控制。这时如果考虑信道的优先级，在功率分配时，可以优先保证优先级高的信道的发射功率。
假设上行信道610为以上实施例中的第一上行信道，重叠区域位于以上第一时域资源，那么上行信道620有部分位于该第一时域资源内，可以将该上行信道620理解为该第一时域资源上的信道。终端在确定第一上行信道的发射功率(S301)时，除了为第一上行信道确定发射功率，还为时域资源与第一上行信道的传输存在重叠的第三上行信道(例如上行信道620)确定发射功率，最终分配给第一上行信道的功率为第一发射功率。
请进一步参考图7，在本实施例中，以上上行信道发送方法还包 括：
S701：终端确定第一上行信道的优先级和第三上行信道的优先级；
S702：终端优先为优先级高的上行信道分配功率。
可见，第一时域资源上除了存在第一上行信道以外，还可能存在其它上行信道的传输与该第一上行信道的传输重叠，还可能存在其他时域资源上的上行信道的传输与该第一上行信道的传输重叠，其他时域资源和第一时域资源可以是相同的时域资源，也可以是不同的。其他时域资源的时间长度可以和第一时域资源的第一时间长度相同，也可以不同。其他时域资源可以是多个时域资源，以下以一个时域资源上的第三上行信道为例，在确定第一上行信道的发射功率时，终端也为该上行信道确定发射功率，最终确定为第一上行信道分配的功率为第一发射功率。为这些信道分配功率时可以按照信道的优先级进行分配，如此可以保证优先级高的信道的发送。
在以上步骤S701中，终端可以根据多种方式确定第一上行信道和第三上行信道的优先级。
在第一种方式中，终端根据第一上行信道的RS的信息和第三上行信道的RS的信息，确定第一上行信道的优先级和第三上行信道的优先级。第一上行信道所在的时域资源为第一时域资源，第三上行信道所在的时域资源为第三时域资源，第一时域资源与第三时域资源在时间上完全重叠或部分重叠，第一时域资源和第三时域资源在时间上重叠小于等于一个门限值，可认为第三时域资源是第一时域资源，即它们可以是有相同编号的时域资源。这里门限值可以是33.21us， 32.47us，或其他值。示例性的，终端根据第一时域资源上是否包含第一上行信道的RS和第三时域资源上是否包含第三上行信道的RS，来确定第一信道的优先级和第三信道的优先级。可选的，令没有RS的信道的优先级高于有RS的信道的优先级，这样可以优先保证没有RS的信道功率满足以上条件要求，即优先分配没有RS的信道的功率。示例性的，当第一时域资源上包括第一上行信道的RS，但第三时域资源上不包括第三上行信道的RS，当第一上行信道的需求功率和第三上行信道的需求功率之和大于第一发射总功率，则优先分配第三上行信道的功率，如果分配完第三上行信道的功率后，功率还有剩余(例如，第一发射总功率-第三上行信道的功率大于零)，再为第一上行信道分配功率，否则第一上行信道的第一发射功率为0；反之亦然。当第一上行信道的需求功率和第三上行信道的需求功率之和小于第一发射总功率时，终端确定第一上行信道的功率和第三上行信道的功率时，为第一上行信道或第三上行信道分配大于上行信道的需求功率的功率，例如为包含RS的时域资源上的信道分配大于信道的需求功率的功率，因为提高信道功率的同时也能提高RS的发射功率，所以能达到提高包含RS的时域资源上的信道的接收正确率的目的。
如果第一时域资源上包括第一上行信道和第三时域资源上包括第三上行信道的RS或者第一时域资源上不包括第一上行信道和第三时域资源上不包括第三上行信道的RS，则在第一上 行信道和第三上行信道的功率和超过了第一发射总功率时，可以等比例压缩这两个上行信道的功率以使得它们的发射功率和不超过第一发射总功率。，等比例压缩功率为A*第一上行信道的需求功率+A*第三上行信道的需求功率+….第i上行信道功率＝第一发射总功率,A可以为小于1的数。当第一上行信道的需求功率和第三上行信道的需求功率之和小于第一发射总功率时，终端确定第一上行信道的功率和第三上行信道的功率时，可以为第一上行信道和第三上行信道分配额外的等量的功率或等比例放大第一上行信道的功率和第三上行信道的功率，以使得第一上行信道和第三上行信道之和大于第一发射总功率，例如额外的等量的功率C＝{第一发射总功率-第一上行信道的需求功率-第三上行信道的需求功率-第四上行信道的需求功率…..第i上行信道功率}/(i-1),或等比例放大功率为B*第一上行信道的需求功率+B*第三上行信道的需求功率+….第i上行信道功率＝第一发射总功率,B可以为大于1的数。当然，也可以以其它因素继续判断它们的优先级。另外，也可以令有RS的信道的优先级高于没有RS的信道的优先级，这样可以优先保证有RS的信道功率。
第二种方式中，终端可以第一上行信道对应的调度信息的接收时间和第三上行信道对应的调度信息的接收时间，确定第一上行信道的优先级和第三上行信道的优先级。例如，终端接收第一上行信道对应的调度信息的时间早于接收第三上行信道 对应的调度信息的时间，可以理解的，这里调度信息的接收时间可以是接收调度信息的绝对时间，例如在子帧a的第c个符号，也可以是以接收调度信息所在具有第一时间长度的时域资源。例如，终端接收第一上行信道对应的的调度信息的时间早于接收第三上行信道的调度信息的时间，即为终端接收第一上行信道对应的调度信息所在的时域资源为第三上行信道对应的的调度信息所在的时域资源之前的时域资源，这说明基站更晚的下发第三上行信道的调度信息，此时已经考虑了之前对于第一上行信道的调度情况，因此该第三上行信道的调度可以有更高的优先级。例如，终端接收第一上行信道对应的的调度信息的时间与接收第三上行信道的调度信息的时间相同，例如，即终端接收第一上行信道对应的调度信息为第三上行信道对应的的调度信息在相同的时域资源或相同编号的时域资源上，那么第一上行信道的优先级与第三上行信道的优先级相同。调度信息是用于触发终端发送信息，调度信息可以是下行控制信息(downlink control information，DCI)中承载的，也可以是下行物理控制信道中承载的，也可以是高层信令中承载的。
可见，当第一上行信道的调度信息的接收时间早于第三上行信道的调度信息的接收时间，第三上行信道的优先级高于第一上行信道；当第一上行信道的调度信息的接收时间晚于第三上行信道的调度信息的接收时间，第一上行信道的优先级高于第三上行信道；当第一上行信道的调度信息的接收时间等于第 三上行信道的调度信息的接收时间时，可以让第一上行信道的优先级等于第三上行信道，也可以再根据其它方式去做判断。
根据优先级来分配信道的功率的方法和第一种方式相同，这里不再赘述。
在第三种方式中，终端可以根据第一上行信道对应的下行传输的接收时间和第三上行信道对应的下行传输的接收时间，确定第一上行信道的优先级和第三上行信道的优先级。上行信道对应的下行传输是指下行数据的传输，该下行数据对应的混合自动重传请求(hybrid automatic repeat request，HARQ)的确认(ACK)或否认(NACK)反馈需要在该上行信道上进行。例如，基站传输下行数据，终端需要在第一上行信道上反馈该下行数据的接收情况，则该第一上行信道对应的下行传输就是该下行数据的传输。基站越早下发的下行数据，需要获得反馈的迫切性越高，因此，用于反馈该下行数据的接收情况的上行信道就具有更高的优先级。下行数据的接收时间可以是接收下行数据信道的绝对时间，也可以是接收下行数据信道所在具有一个时间长度的时域资源。
可见，当第一上行信道对应的下行传输的接收时间早于第三上行信道对应的下行传输的接收时间，第一上行信道的优先级高于第三上行信道；当第一上行信道对应的下行传输的接收时间晚于第三上行信道对应的下行传输的接收时间，第三上行信道的优先级高于第一上行信道；当第一上行信道对应的下行 传输的接收时间等于第三上行信道对应的下行传输的接收时间时，可以让第一上行信道的优先级等于第三上行信道，也可以再根据其它方式去做判断。
根据优先级来分配信道的功率的方法和第一种方式相同，这里不再赘述。
在第四种方式中，终端可以根据第一指示信息确定第一上行信道的优先级和第三上行信道的优先级。其中，第一指示信息可以是基站通过RRC信令或下行控制信息(downlink control information，DCI)发送第一上行信道的优先级和第三上行信道的优先级的指示信息，该指示信息可以是第一上行信道和第三上行信道的优先级，也可以是一个指示的的优先级原则，用于指示优先级的高低顺序。
在第五种方式中，终端可以根据第一上行信道的进程时间和第三上信道的进程时间确定第一上行信道的优先级和第三上行信道的优先级。其中，进程时间越短，优先级越高。进程时间可以通过RRC信令配置或者DCI上承载的传输时延指示信息，来决定的，例如第一上行信道的进程时间是n+4个具有第一时间长度的时域资源，第三上行信道的进程时间是n+3个具有第一时间长度的时域资源，那么第三上行信道的优先级高于第一上行信道的优先级。第一上行信道和第三上行信道具有进程时间，可以让第一上行信道的优先级等于第三上行信道，也可以再根据其它方式去做判断。
在第六种方式中，终端可以根据信道类型来确定信道的优先级，例如控制信道的优先级高于数据信道的优先级。当第三上行信道为上行控制信道时，该上行控制信道用于上行控制信息(uplink control information，UCI)，第一上行信道为上行数据信道时，该上行数据信道用于承载业务数据，第三上行信道的优先级高于第一上行信道的优先级。反之亦然。第一上行信道和第三上行信道是相同的信道类型的信道，可以让第一上行信道的优先级等于第三上行信道，也可以再根据其它方式去做判断。
在第七种方式中，终端可以根据UCI的类型确定信道的优先级。例如，UCI类型的优先级可以为：混合自动重传请求(hybrid automatic repeat request，HARQ)反馈或调度请求(scheduling request，SR)>信道状态信息(channel state information，CSI)。该方式可以结合以上方式，即控制信息的发送大于业务数据的发送优先级。此外，对于相同的UCI，则可以得到如下优先级：HARQ/SR>CSI>业务数据>探测参考信号(sounding reference signal，SRS)。
在第八种方式中，终端可以根据信道所在的时域资源的长短来确定优先级，时域资源越短的信道的优先级越高。例如，当第三上行信道所在的时域资源为1ms的时域资源，且第一上行信道所在的时域资源为小于或等于0.5ms的时域资源，那么第一上行信道的优先级高于第三上行信道的优先级。当第一上行信道和第三上行信道所在相同时间长度的时域资源时，可以让第一上行信道的优先级等于第三上行信道，也可以再根据其它方式去做判断。
在第九种方式中，可以承载无线资源控制(radio resource control，RRC)信令的信道高于不承载RRC信令的信道，例如主小区组(master cell group，MCG)的信道优先级高于辅小区组(secondary cell group，SCG)的信道。例如，当第三上行信道为辅小区组的信道，且第一上行信道承载的是主小区组的信道，那么第一上行信道的优先级高于第三上行信道的优先级。当第一上行信道和第三上行信道为相同的小区组的信道时，可以让第一上行信道的优先级等于第三上行信道，也可以再根据其它方式去做判断。
以上这些方式仅为举例并非用于限制本发明，且这些方式可以部分或全部结合使用，且可以设定各个方式之间的优先级顺序，且按设定的顺序依次利用选择的方式判断信道间的优先级，当所有选择的方式都判断过后，信道优先级相同时，可以等比例压缩信道的功率。
例如，结合以上几种方式得到的一种优先级顺序为：短TTI物理上行控制信道(sPUCCH)>没有DMRS但有UCI的短TTI的物理上行数据信道(例如，物理上行共享信道，sPUSCH without DMRS and with UCI)>没有DMRS也没有UCI的短TTI的物理上行数据信道(例如，物理上行共享信道，sPUSCH without DMRS and without UCI)>常规TTI的物理上行控制信道(PUCCH)>有UCI的常规TTI的物理上行数据信道(例如，物理上行共享信道，PUSCH with UCI)>没有UCI的常规TTI的物理上行数据信道(例如，物理上行共享信道，PUSCH without UCI)>有DMRS而没有UCI的短TTI的物理上行数据信道(例如，物理上行共享信道，sPUSCH with DMRS and without  UCI)>SRS。
在以上步骤S702中，终端优先为优先级高的上行信道分配功率的过程中，终端可能为优先级低的上行信道分配功率，也可能因为功率的限制不为优先级低的上行信道分配功率。例如，当第一上行信道上没有RS时，在第一发射总功率允许的情况下，可以继续为优先级低的上行信道分配功率。例如第三上行信道的优先级高于第一上行信道时，为第三上行信道分配功率，在第一发射总功率减去为第三上行信道分配的功率还有剩余足以分配给第一上行信道时，则为第一上行信道分配功率，否则放弃发送第一上行信道。反之亦然。当第一上行信道上有RS且第三信道上有RS时，在终端允许的最大发射功率的情况下，可以继续为优先级低的上行信道分配功率。例如第三上行信道的优先级高于第一上行信道时，为第三上行信道分配功率，在终端允许的最大发射功率减去为第三上行信道分配的功率还有剩余足以分配给第一上行信道时，则为第一上行信道分配功率，否则放弃发送第一上行信道。
请继续参考图8，其为本发明实施例提供的又一种上行信道发送方法的示意图。在本实施例中，第一时域资源和其它时域资源在时间上存在重叠区域，为了方便说明，该其它时域资源以下称为第四时域资源。终端确定第一时域资源和第四时域资源在重叠区域的优先级，且优先进行优先级高的时域资源上的传输。此时，该方法包括如下步骤：
S801：终端确定第一时域资源和第四时域资源在重叠区域的优先 级；
S802：终端在重叠区域优先进行优先级高的时域资源上的传输。
以上重叠可能是由定时提前(timing advance，TA)调整引起的，此时，第一时域资源和第四时域资源所在的载波可以属于相同TA组(TAG)，第一时域资源和第四时域资源也可以是在相同的载波。
可选的，当第四时域资源和第一时域资源的重叠区域不超过一个符号时，终端确定第一时域资源和第四时域资源在重叠区域的优先级之后，通过优先级来终端确定在重叠区域的传输，此时因为重叠的区域；当重叠区域超过了一个符号，那么说明两个时域资源重叠部分较大，应通过第一时域资源上的第一上行信道的优先级和第四时域资源上的第四上行信道的优先级，来确定分配的信道分配的功率或优先传输哪个信道。需要说明的是，这里是按照一个符号来示例，具体应用也可以是小于一个符号或大于一个符号的时间段。
可选的，第四时域资源的时域资源编号和第一时域资源的编号不同。
可选的，当两个时域资源的长度是相同的时，那么重叠区域等于时域资源的长度-两个时域资源上的传输发射时间差。
其中，本发明中符号为正交频分复用(orthogonal frequency division multiplexing，OFDM)符号或单载波频分多址(single carrier frequency division multiplexing，SC-FDMA)符号
在以上步骤S801中，终端可以根据第一时域资源和第四时域资源上RS的信息来确定第一时域资源和第四时域资源在重叠区域 的优先级。
例如，请参考图9A或者图9B，第一时域资源和第四时域资源在时间上存在重叠的区域。如图9A或者图9B所示，当重叠区域内包括第一时域资源上的RS，不包括第四时域资源上的RS时，第一时域资源的优先级高于第四时域资源的优先级。当重叠区域内包括第四时域资源上的RS，不包括第一时域资源上的RS时，第四时域资源的优先级高于第一时域资源的优先级。
当重叠区域既包括第一时域资源上的RS又包括第二时域资源上的RS，或者两个时域资源上的RS都不包括时，终端可以进一步根据第一时域资源和第四时域资源的时间长度来确定它们的优先级，例如时间长度大的时域资源的优先级高。当然，也可以进一步根据其它策略来确定优先级。
当所述重叠区域内包括所述第一时域资源上的参考信号和所述第四时域资源上的参考信号，或所述重叠区域内不包括所述第一时域资源上的参考信号和所述第四时域资源上的参考信号时，时间长度大的时域资源的优先级高；或者
当所述重叠区域内包括所述第一时域资源上的参考信号和所述第四时域资源上的参考信号，或所述重叠区域内不包括所述第一时域资源上的参考信号和所述第四时域资源上的参考信号时，起始时刻靠前的时域资源的优先级高。
需要说明的是，如果终端具有同时传输多个时域资源的能力和/或基站配置终端同时传输多个时域资源且多个时域资源上 的信息在频域上没有重叠的部分，可既进行优先级高的时域资源上的传输，又进行优先级低的时域资源上的传输，但是如果终端部具有同时传输多个时域资源的能力或基站未配置终端同时传输多个时域资源或多个时域资源上的信息在频域上有重叠的部分，那么终端至少对于频域上重叠的时域资源可以只进行优先级高的时域资源上的传输，而丢弃优先级低的时域资源在重叠区域的传输。
在另一种实现方式中，对于时间长度不同的重叠的时域资源，终端可以根据第一时域资源和第四时域资源的时间长度以及重叠区域上包括的RS的信息，来确定第一时域资源和第四时域资源在重叠区域的优先级。
例如，当第一时域资源的时间长度大于第四时域资源的时间长度，且重叠区域内包括第一时域资源上的RS时，第一时域资源的优先级高于第四时域资源的优先级，此时对于重叠区域内是否有第四时域资源的RS可以不做考虑。当第四时域资源的时间长度大于第一时域资源的时间长度，且重叠区域内包括第四时域资源上的RS时，第四时域资源的优先级高于第一时域资源的优先级，此时对于重叠区域内是否有第一时域资源的RS可以不做考虑。
在一实施例中，可以设定PA的保证功率，使得多载波、多信道发射时，PA可以使用与上次相同的发射功率，如此可以保证以上第一发射总功率的不变，即多个时域资源上的对应该PA的至少一 个上行信道的发射功率之和相等，从而基站可以利用多个时域资源上的上行信道的同一个RS正确解调这些上行信道。
可选的，终端接收第二指示信息，第二指示信息用于指示至少一个PA上的保证功率，第二指示信息可以是承载在DCI信息或高层信令中。
该PA的保证功率可以是基站设置并发送给终端的，也可以是终端预设的最小保证功率，具体的保证功率可以是一个具体的功率数值，也可以是与终端允许的最大发射功率的比例值。
此时，终端确定第一上行信道的第一发射功率之前，以上图3所示的方法还包括：终端获取第一上行信道对应的PA的保证功率，该PA对应的至少一个上行信道的功率之和小于或等于该保证功率。此时，终端可以根据该保证功率，确定第一发射功率，其中第一发射功率小于或等于该保证功率，且PA对应的至少一个上行信道的功率之和小于或等于该保证功率。
在基站为终端配置保证功率的情况下，终端还可以在接收保证功率之前，终端上报该终端上的PA与上行信道的对应关系，或者上报PA与上行载波/上行载波组的对应关系。当然，也可以这两个都上报。
在以上实施例中，终端可以自行决定是否在第一时域资源上发送第一上行信道的RS，也可以根据基站的指示来确定是否在第一时域资源上发送第一上行信道的RS，用来避免RS的功率与上行信道的功率不同导致无法正确接收上行信道的问题。例如，当终端接收到基 站发送的指示信息，该指示信息指示终端在第一时域资源上发送第一上行信道的RS。
终端自行决定时，可以在以下情况下在第一时域资源上发送第一上行信道的RS：
第一时域资源内终端允许的最大发射功率小于所述第二时域资源内终端允许的最大发射功率；
第一时域资源上的上行信道数量发生变化；
第一时域资源上的上行信道发射功率之和大于第一时域资源内终端允许的最大发射功率；
终端连续进行W个时域资源上的传输，且所述连续W个时域资源上都不包括参考信号，其中W大于1的预设整数；
第一时域资源与第二时域资源之间存在未进行传输的预设时间间隔；
终端的在时域上存在重叠的上行载波数量发生变化。
在以上实施例中，终端上报该终端是否具有多个时域资源的RS为同一个RS的能力。以便基站可以根据终端的能力进行是否指示该终端发送上行信道所在的多个时域资源的RS为同一个，避免了终端PA本身容易跳变，导致使用同一个RS的上行信道无法正确接收。可选的，终端接收基站配置的多个时域资源的RS为同一个RS的指示信息。
在以上实施例中，终端上报至少一个基站的信道发送情况。例如，基站间是非理想回程的交互，即不能实时进行通信，那么当终端同时 向至少两个基站进行通信的时候，需要上报其他基站的上行信道的发送情况，以避免当基站调度多个时域资源的RS为同一个RS时，由于功率不足导致的，RS和上行信道的发射功率不同从而引起相位不同，导致不能正确接收上行信道。
在以上实施例中，终端只使用上行数据信道承载UCI或者不使能在一个载波上上行控制信道与上行数据信道同传，以避免多个时域资源的RS为同一个RS时，由于同时在一个载波上多个信道功率不足导致的，RS和上行信道的发射功率不同从而引起相位不同，导致不能正确接收上行信道。
本发明实施例还提供一种上行数据的传输方法，执行主体是基站，请参考图10A，所述方法包括以下步骤：
S1001：基站确定终端的第一上行信道的参考信号是否在具有第一时间长度的第一时域资源上发送；所述参考信号用于所述第一上行信道的解调。
S1002：当确定发送所述参考信号时，所述基站向所述终端发送指示信息。其中，所述指示信息用于指示所述终端在所述第一时域资源上发送所述第一上行信道的参考信号。
可选的，如图10B所示，基站通过以下方式确定终端的第一上行信道的参考信号是否需要在具有第一时间长度的第一时域资源上发送，
S1003：所述基站判断差值是否大于第一门限值。其中所述差值为所述终端在第一时域资源上发送上行载波的数量与第二 时域资源上发送上行载波的数量的差值，或者，所述差值为所述终端在第一时域资源上发送上行信道的数量与第二时域资源上发送上行信道的数量的差值；
S1004：当所述差值大于第一门限值时，所述基站确定终端的第一上行信道的参考信号在具有第一时间长度的第一时域资源上发送。

第一确定单元1101用于确定第一上行信道的第一发射功率，其中，第一上行信道是在具有第一时间长度的第一时域资源上的至少一个上行信道中的一个信道。发送单元1102用于以第一确定单元1101确定的第一发射功率发送第一上行信道。
关于第一确定单元1101确定第一发射功率的方式同以上方法实施例，在此不再赘述。
另外，关于时域资源的时间长度、第一时域资源上不包括第一上行信道的参考信号以及第一时域资源上包括第一上行信道的参考信号的情况、第一时域资源上的至少一个上行信道和第二时域资源上的至少一个上行信道等的描述同以上实施例。
请继续参考图11，可选的，可选的，装置1100还可以包括配置单元1103，用于在第一确定单元1101确定第一发射功率之 前，配置第一时域资源内终端允许的最大发射功率等于第二时域资源内终端允许的最大发射功率。
可选的，装置1100还可以包括获取单元1104，用于在第一确定单元1101确定第一发射功率之前，获取第一上行信道对应的功率放大器的保证功率，该功率放大器对应的至少一个上行信道的功率之和小于或等于所述保证功率。该保证功率的获取方式同以上实施例，在此不再赘述。此外，当从基站获取保证功率时，以上发送单元1102还可以用于上报功率放大器与上行信道的对应关系，和/或，功率放大器与上行载波/上行载波组的对应关系。
可选的，当第一上行信道的传输与第三上行信道的传输在时间上存在重叠时，第一确定单元1101用于，确定第一上行信道和第三上行信道的优先级；优先为优先级高的上行信道分配功率。
关于第一上行信道和第三上行信道的优先级的确定方法同以上实施例，在此不再赘述。可选的，当第一时域资源和第四时域资源在时间上存在重叠区域时，如图12所示的装置1200，相对于图11所示的装置还包括：
第二确定单元1201，用于确定第一时域资源和第四时域资源在重叠区域的优先级；
传输单元1202，用于在重叠区域优先进行优先级高的时域资源上的传输。
其中，第二确定单元1201确定第一时域资源和第四时域资源在重叠区域的优先级的方法同以上实施例，在此不再赘述。
