Description

一种上行控制信道聚合发送和接收方法、终端和基站 技术领域
本发明涉及长期演进高级系统(LTE-Advanced，Long Term Evolution advanced system)领域，尤其涉及一种上行控制信道聚合发送和接收方法、终端和基站。
背景技术
在长期演进系统(LTE，Long Term Evolution system)中，终端的上行信道包括物理上行共享信道(PUSCH)、物理上行控制信道(PUCCH)和物理随机接入信道(PRACH)。PUSCH中可以传输数据信息、调度请求(SR)、混合自动重传请求(HARQ)和信道状态信息(CSI)；PUCCH中可以传输SR、HARQ和CSI；PRACH主要用于终端的上行接入，包括在配置的时频资源上发送前导码(Preamble)进行随机接入。基站接收到终端发送的Preamble需要给终端发送Msg2消息用于随机接入响应，如果终端为基于非竞争随机接入，终端接收到Msg2消息即认为随机接入成功；如果终端为基于竞争随机接入，终端接收到Msg2消息后还需要发送Msg3消息用于随机接入冲突解决，基站接收到终端发送的Msg3后需要给终端发送Msg4用于随机接入冲突解决指示，终端接收到基站发送的Msg4中的竞争解决标识和Msg3中的竞争解决标识一致时，终端认为竞争解决成功。
在现有技术中，载波聚合(CA)场景下，如果多个分量载波出现聚合发送，由于随机接入仅仅在主小区(Pcell)上发送，PUCCH也仅仅在Pcell上发送，这时不会出现多个载波上同时发送随机接入信道以及PUCCH的过程。当多个载波的PUSCH同时传输时，如果功率受限，多个PUSCH的功率和超出了终端支持的最大功率值，则优先保证带有上行控制信息(UCI) 的PUSCH的功率，然后其他载波的PUSCH采用等功率分配。当PUCCH和PUSCH同时传输时，如果功率受限，PUCCH和一个或者多个PUSCH的功率和超出了终端支持的最大功率值，则首先保证PUCCH的功率，其次保证带有UCI的PUSCH的功率，然后其他PUSCH采用等功率分配。由于CA场景主要考虑理想回程(backhual)，多个载波间的调度信息相互共享，功率分配信息也相互及时共享，这时多个载波间可以相互协作避免超出终端的最大功率，当超出终端最大功率时，多个载波机可以预测并且计算对应的终端对于各个载波和信道的调整值。
HARQ绑定主要是指，多个子帧的HARQ信息在一个子帧上反馈，主要是时域的绑定，多个子帧上对应码字的HARQ信息进行比特“与”操作。
HARQ复用主要是指，一个子帧内的两个码字间的绑定，主要是空域的绑定，一个子帧内两个码字HARQ信息进行比特“与”操作。
在R12阶段考虑引入双链接技术，双链接技术与CA的最大区别在于双链接的两个基站(eNB)采用了非理想backhual连接，两个节点之间的调度独立。由于引入了独立调度，两个载波不能动态的共享上行调度信息以及对应的功率控制信息，这时如果两个载波独立配置最大功率值，会导致上行功率受限浪费；如果不进行独立限制，两个eNB配置的信道会导致终端发送两个eNB上的信道功率和超出终端支持的最大功率值。这时需要引入一种解决机制，来保证终端在双链接场景下，可以处理这种功率受限的多上行信道发送的方案。

在一种实施方式中，基站预设当主服务基站的HARQ和辅服务基站的HARQ中包含至少一个CSI信息时，如果主服务基站和辅服务基站的HARQ和CSI的比特数数目超过22比特，丢弃所有CSI信息。
在一种实施方式中，基站预设当主服务基站和辅服务基站的HARQ中包含至少一个CSI信息和SR信息时，如果主服务基站和辅服务基站的HARQ、CSI和SR的比特数数目超过22比特，丢弃所有CSI信息。
在一种实施方式中，基站预设当主服务基站和辅服务基站的HARQ中包含CSI信息时，如果主服务基站的HARQ和CSI的比特数、以及辅服务基站的HARQ和CSI的比特数目超过22比特，但是两个HARQ信息和一个CSI信息没有超过22比特，只传输优先级最高的CSI信息。
在一种实施方式中，基站预设当主服务基站和辅服务基站的HARQ中包含CSI信息时，如果主服务基站的HARQ和CSI的比特数、以及辅服务基站的HARQ和CSI的比特数目超过22比特，两个HARQ信息和一个CSI信息也超过22比特，并且HARQ采用绑定或复用传输的比特数目与一个CSI信息比特数目和没有超过22比特，只传输优先级最高的CSI信息，HARQ进行绑定或复用操作。
下面举例对上述上行控制信道聚合发送和接收方法进一步详细说明。
在双链接场景中存在至少两个基站(eNB)，分别称为MeNB和SeNB，MeNB为主服务基站，SeNB为非主服务基站(或者称为辅服务基站)，主服务基站可以负责给终端发送SeNB的一些系统消息和一些高层配置信令。 MeNB和SeNB可以实现独立的媒体接入控制(MAC)层调度。
MeNB下可以配置多个服务小区(载波)，其中一个为MeNB的主服务小区，称为MPcell，MeNB下所有服务小区的上行PUCCH仅仅在MPcell对应的载波上传输，而且终端仅仅在MPcell上检测MeNB的系统信息和寻呼消息。
SeNB下可以配置多个服务小区(载波)，其中一个为SeNB的主服务小区，称为SPcell，SeNB下所有服务小区的上行PUCCH仅仅在SPcell对应的载波上传输，而且终端仅仅在SPcell上检测SeNB中不同标识(TAG)小区(载波)对应的上行随机接入响应信息(Msg2)。
本发明实施例中的HARQ也可以称为ACK/NACK。
本发明实施例中的PUCCH资源元素可以为配置PUCCH Format3的资源元素。
实施例一：
假设存在MeNB和SeNB这两个双链接eNB，存在一个双链接终端(UE)，所述UE在MeNB和SeNB上建立双链接。当终端采用聚合方式发送MeNB和SeNB的UCI时，如果采用半静态的方式利用高层信令配置终端发送PUCCH资源元素位置，且仅仅支持在MeNB上发送，那么两个eNB可以协商配置一个公共PUCCH资源元素位置。终端接收基站配置的所述公共PUCCH资源元素位置，只要终端采用聚合方式发送MeNB和SeNB的UCI信息，那么终端就在所述公共PUCCH资源元素位置进行发送。
实施例二：
假设存在MeNB和SeNB这两个双链接eNB，存在一个双链接UE，所述UE在MeNB和SeNB上建立双链接。当终端采用聚合方式发送MeNB和SeNB的UCI时，如果采用半静态的方式利用高层信令配置终端发送PUCCH资源元素位置，且仅仅支持在MeNB上发送，那么两个eNB可以 协商配置N(N>0)个公共PUCCH资源元素位置。终端接收基站配置的所述N个公共PUCCH资源元素位置，只要终端采用聚合方式发送MeNB和SeNB的UCI信息，那么终端就可以在所述N个公共PUCCH资源元素位置之一进行发送。
终端根据MeNB或者SeNB发送的对应下行授权(DL Grant)中比特指示来选择N个公共PUCCH资源元素位置之一进行发送。
在一种实施方式中，所述DL Grant中比特为重用TPC(Transmission Power Control，传输功率控制)比特。
在一种实施方式中，当所述DL Grant来自于MeNB时，对应PUCCH的参考信号采用SeNB的参考信号；当所述DL Grant来自于SeNB时，对应PUCCH的参考信号采用MeNB的参考信号和序列，对应的所述参考信号和序列可以包括以下信息至少之一：
参考信号序列，PUCCH对应的扰码序列，参考信号扩频序列，参考信号循环移位序列，PUCCH对应的扩频序列，PUCCH对应的循环移位序列。
对于基站侧，如果DL Grant为MeNB发送，或者PUCCH资源为MeNB的载波或者小区，这时MeNB在对应DL Grant中指示的资源上检测PUCCH。SeNB需要利用所述终端在SeNB配置的如下信息至少之一：
参考信号序列，PUCCH对应的扰码序列，参考信号扩频序列，参考信号循环移位序列，PUCCH对应的扩频序列，PUCCH对应的循环移位序列。
检测N个公共的PUCCH，在对应的位置检测到对应的序列信息，即认为终端在对应的PUCCH资源发送了所述终端的PUCCH。
以上实施例一和实施例二解决了MeNB和SeNB如何识别终端聚合反馈的PUCCH位置的问题。
以下实施例解决的问题为：由于MeNB中在某一个时刻调度的CCs(Component Carriers，元素载波)数目，SeNB是不知道的，所以SeNB在 检测自己的CCs数目时，无法准确获得终端映射SeNB的UCI比特位置。这时需要一些方案保证MeNB和SeNB的UCI的资源元素映射在基站侧和终端侧有一致的理解。
实施例三：
假设存在MeNB和SeNB这两个双链接eNB，存在一个双链接UE，所述UE在MeNB和SeNB上建立双链接。当终端采用聚合方式发送MeNB和SeNB的UCI时，按照MeNB和SeNB的配置的CCs数目决定。
例如：MeNB上配置了N0个CCs，那么终端按照对应CCs最大所需HARQ比特数数目进行预留，然后在预留的比特数目之后映射SeNB的HARQ，即SeNB第一个服务小区或者小区索引最低服务小区的HARQ比特的起始位置为MeNB预留的最后一个HARQ资源元素位置的下一个位置。如图2所示。
在一种实施方式中，如果SeNB最后几个HARQ比特超出了分配的PUCCH资源元素，那么终端对SeNB的所有HARQ比特进行Bundling或者Multiplexing操作。
实施例四：
假设存在MeNB和SeNB这两个双链接eNB，存在一个双链接UE，所述UE在MeNB和SeNB上建立双链接。当终端采用聚合方式发送MeNB和SeNB的UCI时，按照MeNB和SeNB的配置的CCs数目决定。
例如：MeNB上配置了N0个CCs，那么终端按照对应CCs最大所需HARQ比特数数目进行预留，然后在预留的比特数目之后映射SeNB的HARQ，即SeNB第一个服务小区或者小区索引最低服务小区的HARQ比特的起始位置为MeNB预留的最后一个HARQ资源元素位置的下一个位置。如图3所示。
在一种实施方式中，如果SeNB最后几个HARQ比特超出了分配的 PUCCH资源元素，那么终端对SeNB所述最后几个HARQ比特在MeNB预留的HARQ资源元素上逆序映射。如图3所示。
例如：MeNB预留的PUCCH资源元素为R0～R(X-1)，SeNB预留的资源元素为RX～R(Y-1)；如果MeNB实际的HARQ0～HARQ(Z-1)仅仅占用了R0～R(Z-1)，SeNB的HARQZ～HARQ(Y-S-1)需要占用(Y-S-Z)个PUCCH资源，HARQ0～HARQ(Z-1)分别对应映射到R0～R(Z-1)。HARQZ～HARQ(Y-X+Z-1)映射到RX～HARQ(Y-1)，HARQ(Y-X+Z)～HARQ(Y-S-1)映射到R(X-1)～R(S+Z)。其中，0<Z<X+1，-1<S<X-Z+1，Y>X，X>0，X、Y、Z、S均为整数。
实施例五：
假设存在MeNB和SeNB这两个双链接eNB，存在一个双链接UE，所述UE在MeNB和SeNB上建立双链接。当终端采用聚合方式发送MeNB和SeNB的UCI时，MeNB从PUCCH低索引资源到高索引资源映射，SeNB从PUCCH高索引资源到低索引资源映射。
例如：MeNB上配置了N0个CCs，如图4所示，终端从PUCCH索引最低资源开始映射到高PUCCH索引资源，直至映射完MeNB上所有HARQ信息，终端从PUCCH索引最高资源开始映射到低PUCCH索引资源，直至映射完SeNB上所有HARQ信息。
例如：MeNB的HARQ分别为HARQ 0～HARQ N0-1，SeNB的HARQ分别为HARQN0～HARQN1-1，存在PUCCH资源编号为：R0～RN0-1和RN0～RN1-1。
映射方式为：MeNB的HARQ0～HARQN0-1按照顺序一一映射到R0～RN0-1，HARQN0～HARQN1-1按照顺序一一映射到RN1-1～RN0。
实施例六：
假设存在MeNB和SeNB这两个双链接eNB，存在一个双链接UE，所述UE在MeNB和SeNB上建立双链接。当终端采用聚合方式发送MeNB 和SeNB的UCI时，当MeNB和SeNB的UCI信息超出了分配的PUCCH资源容量，那么终端对于MeNB和SeNB的所有UCI中的HARQ信息比特进行Bundling或者Multiplexing操作。
在一种实施方式中，终端通过N(N>0)个比特指示基站当前PUCCH是否进行了Bundling或者Multiplexing操作，N个比特和UCI信息一起承载在PUCCH资源元素中，基站可以先检测N个比特指示信令来判断基站是否进行Bundling或者Multiplexing操作，然后进行相关HARQ检测操作。
其中，N的取值为1。
实施例七：
当MeNB UCI上不仅仅传输HARQ信息时，存在以下几种配置场景：
场景1：MeNB上传输HARQ，SeNB上传输HARQ+SR
场景2：MeNB上传输HARQ，SeNB上传输HARQ+CSI
场景3：MeNB上传输HARQ，SeNB上传输HARQ+CSI+SR
场景4：MeNB上传输HARQ+SR，SeNB上传输HARQ
场景5：MeNB上传输HARQ+SR，SeNB上传输HARQ+SR
场景6：MeNB上传输HARQ+SR，SeNB上传输HARQ+CSI
场景7：MeNB上传输HARQ+SR，SeNB上传输HARQ+CSI+SR
场景8：MeNB上传输HARQ+CSI，SeNB上传输HARQ
场景9：MeNB上传输HARQ+CSI，SeNB上传输HARQ+SR
场景10：MeNB上传输HARQ+CSI，SeNB上传输HARQ+CSI
场景11：MeNB上传输HARQ+CSI，SeNB上传输HARQ+CSI+SR
场景12：MeNB上传输HARQ+CSI+SR，SeNB上传输HARQ
场景13：MeNB上传输HARQ+CSI+SR，SeNB上传输HARQ+SR
场景14：MeNB上传输HARQ+CSI+SR，SeNB上传输HARQ+CSI
场景15：MeNB上传输HARQ+CSI+SR，SeNB上传输HARQ+CSI+SR
对于场景1、2、3、4、5、6、8、9、12，如果MeNB和SeNB所有的UCI比特超过了分配PUCCH的最大容量，那么终端对HARQ进行Multiplexing操作。
对于场景7，如果MeNB和SeNB所有的UCI比特超过了分配PUCCH的最大容量，那么终端对HARQ进行Multiplexing操作，如果HARQ Multiplexing比特仍然超出了PUCCH最大容量，那么终端丢弃CSI信息。
对于场景10、13：如果MeNB和SeNB所有的UCI比特超过了分配PUCCH的最大容量，那么终端对HARQ进行Multiplexing操作，如果HARQ Multiplexing比特仍然超出了PUCCH最大容量，那么终端丢弃优先级低的CSI信息或者丢弃SeNB上传输的CSI信息。
对于场景11、14：如果MeNB和SeNB所有的UCI比特超过了分配PUCCH的最大容量，那么终端对HARQ进行Multiplexing操作，如果HARQ Multiplexing比特仍然超出了PUCCH最大容量，那么终端丢弃优先级低的CSI信息或者丢弃SeNB上传输的CSI信息。
对于场景15：如果MeNB和SeNB所有的UCI比特超过了分配PUCCH的最大容量，那么终端对HARQ进行Multiplexing操作，如果HARQ Multiplexing比特仍然超出了PUCCH最大容量，丢弃优先级低的CSI信息或者丢弃SeNB上传输的CSI信息。丢弃后，如果HARQ Multiplexing比特仍然超出了PUCCH最大容量，那么丢弃另外一个CSI信息。
或者，
对于场景15：如果MeNB和SeNB所有的UCI比特超过了分配PUCCH的最大容量，那么终端对HARQ进行Multiplexing操作，如果HARQ Multiplexing比特仍然超出了PUCCH最大容量，丢弃所有CSI信息。
其中，终端可以利用S比特指示基站是否发生了CSI丢弃。
其中，S的取值为1，这时终端仅仅通知基站是MeNB或者SeNB上的 CSI发生了丢弃。基站获得对应比特后，就可以获知丢弃了哪一个CSI。
例如：
对于场景7，由于仅仅SeNB发送了CSI，如果S比特指示SeNB丢弃，那么基站获知对应PUCCH资源没有承载CSI信息。
其中，方法1：S＝1，S对应比特值为0，那么指示MeNB的CSI丢弃，S对应比特值为1，那么指示SeNB的CSI丢弃；
或者，方法2：S对应比特值为0，那么指示SeNB的CSI丢弃，S对应比特值为1，那么指示MeNB的CSI丢弃。
对于场景7，由于仅仅SeNB携带CSI，如果丢弃对应的SeNB的CSI，那么按照方法1，S对应比特取值为1，SeNB检测到对应的比特就可以获知对应CSI被丢弃；如果S对应比特取值为0，由于MeNB上没有携带CSI，那么对于MeNB的检测没有影响，对于SeNB由于认为SeNB的CSI没有丢弃，所以可以检测CSI信息。
对于场景10、11、14和15，由于MeNB和SeNB携带CSI，如果丢弃对应的SeNB的CSI，那么按照方法1，S对应比特取值为1，SeNB检测到对应的比特就可以获知对应CSI被丢弃；如果S对应比特取值为0，由于MeNB上携带CSI，那么对于MeNB会知道对应CSI丢弃，对于SeNB由于认为SeNB的CSI没有丢弃，所以可以检测CSI信息。
对于场景13，由于MeNB仅仅携带CSI，如果丢弃对应的MeNB的CSI，那么按照方法1，S对应比特取值为0，MeNB检测到对应的比特就可以获知对应CSI被丢弃；如果S对应比特取值为1，由于SeNB上没有携带CSI，那么对于SeNB的检测没有影响，对于MeNB由于认为MeNB的CSI没有丢弃，所以可以检测CSI信息。
