Description

信道冲突处理方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种信道冲突处理方法及装置。
背景技术
由于新无线(new radio，NR)引入了波束的概念，高频波束成形技术引入的波束扫描延迟导致切换中断时间增加。此外，波束成形特性形成了较小的覆盖范围，因此也会造成切换的可靠性降低。当终端设备移动或旋转时，终端设备可以经历非常快速的信号劣化；而且NR中的直视径(line of sight，LoS)和非直视径(non line of sight，NLoS)之间的信道条件差异较大，LOS与NLOS之间的信号强度波动达到几十dB。这可能导致更多的切换失败和更高概率的乒乓切换。因此，在NR中的切换相比长期演进(long-term evolution，LTE)通信系统更具挑战性。
此外，NR的超高可靠低时延通信(ultra reliable&low latency communication，URLLC)类型的业务，在某些情况下需要1ms的端到端延迟。0ms切换中断对提供无缝服务体验有重要意义。
双连接协议栈(dual active protocol stack，DAPS)切换方案可以实现0ms切换中断。如图1所示的DAPS切换流程示意图，源小区(source cell)给终端设备发送切换命令(handover command，HO cmd)，终端设备与目标小区(target cell)发起接入，然后，终端设备在目标小区上接入完成。在该方案中，在终端设备发起接入后，终端设备继续和源小区通信，即图1中所示的双小区连接(简称“双连接”)区间。最后，删除源小区后，终端设备只在目标小区上通信，完成切换。由于在切换过程中，终端设备同时在源小区和目标小区上通信，实现了0ms切换中断。
对于同频同步/异步和带内连续的同步/异步场景下，终端设备的射频收发和处理结构如图2所示，其中，终端设备的源小区的基带处理(base band process，BBP)模块和目标小区的BBP模块连接至同一个射频(radio frequency，RF)模块，或者称源小区的BBP通道和目标小区的BBP通道连接至同一个RF通道，这样可以节省终端设备的功耗。
当终端设备的源小区和目标小区的BBP通道连接至同一个RF通道时，终端设备可能同时向源小区和目标小区发送信息，那么就可能产生源小区和目标小区的上行信道冲突。如何减少上行信道冲突带来的负面影响是本申请需要解决的问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
本申请实施例所涉及到的终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的 用户设备(user equipment，终端设备)，移动台(mobile station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为终端设备。
基于背景技术描述的问题，请参阅图3，图3为本发明实施例提供的一种信道冲突处理方法流程示意图，如图3所示，所述方法包括如下步骤：
301、当所述终端设备与源小区已建立连接关系，且向所述目标小区发送连接请求或建立连接关系时，所述终端设备检测是否发生上行信道冲突，所述上行信道包括所述源小区的上行信道和所述目标小区的上行信道。
DAPS对应一种旨在达成0ms切换的场景，在这个场景中，源小区是指终端设备已经建立连接的通信小区，目标小区是另一个终端设备预计切换到的通信小区。具体过程如图1所示，如果从图中所示的切换命令开始，终端设备和源小区即断开连接，直到切换完成和目标小区建立新的连接，终端设备通信中断至少50ms以上；但是基于DAPS的切换，切换命令后，终端设备继续和源小区通信，在目标小区上接入完成后和目标小区建立连接，终端设备同时在两个小区上通信，即图中双小区连接区间；最后源小区删除后，终端设备只在目标小区上通信，完成切换。
在其他场景中，源小区是指终端设备已经建立连接的通信小区，目标小区可以是终端设备试图建立连接的通信小区，也可以是终端设备已经连接的通信小区。
在上述连接场景中，以DAPS切换场景为例，目标小区和源小区组成的网络有以下场景：
同频(Intra-freq)同步；
同频(Intra-freq)异步；
带内连续的异频(intra-band，inter-freq)同步；
带内连续的异频(intra-band，inter-freq)异步；
带内非连续的异频(intra-band，inter-freq)同步；
带内非连续的异频(intra-band，inter-freq)异步；
带间的异频(inter-band，inter-freq)同步；
带间的异频(inter-band，inter-freq)异步；
为了实现基于DAPS的切换，终端设备需要同时处理两个小区的信号收发，因此需要2套收发处理装置，每套装置包括射频(RF)处理装置和基带处理(BBP)装置。为了节省功耗，同频和带内连续两种场景下的2套收发处理装置可以共用一套射频(RF)处理装置。
这些场景中，终端设备需要的的射频(RF)处理装置和基带处理(BBP)装置数量的对应关系如表1所示：
表1
场景 基带处理(BBP)装置 射频(RF)处理装置
同频同步 2 1
同频异步 2 1
带内连续的异频同步 2 1
带内连续的异频异步 2 1
带内非连续同步 2 2
带内非连续异步 2 2
带间同步 2 2
带间异步 2 2
在带内非连续同步/异步，以及带间同步/异步场景下，两个BBP通道对应两个RF通道，没有上行通道冲突的问题。在同频同步/异步，以及带内连续的异频同步/异步场景下，两个BBP通道对应一个RF通道，终端设备的射频收发和处理结构如图2所示，可能产生源小区和目标小区的上行发送通道冲突。
可选的，检测是否发生源小区和目标小区的上行信道冲突，包括：在终端设备向目标小区发起接入请求后，在目标小区接入成功前，检测目标小区的随机接入相关信道与源小区的上行共享信道PUSCH，上行控制信道PUCCH或探测参考信道SRS之间是否发生符号级冲突，随机接入相关信道包括物理随机接入信道PRACH、发送msg3的PUSCH信道、用于msg4上行ACK/NACK反馈的PUCCH或用于发送msgA信号的PUCCH和PUSCH信道。
可选的，检测是否发生与源小区和目标小区的上行信道冲突，包括：在目标小区接入成功后，在终端设备断开与源小区的连接前，检测目标小区的PUSCH、PUCCH或SRS与源小区的PUSCH、PUCCH或SRS之间是否发生符号级冲突。
本申请实施例中所表明的上行信道冲突，皆是指符号级冲突，符号级冲突是指两个小区的上行发送在时间域上重叠。如果没有符号级的冲突，可以时分复用合并发射不同上行信道中的信息。
目标小区和源小区的上行信道冲突可能发生在图1中的切换命令～删除源小区阶段，请参阅图4，图4为本申请实施例提供的一种上行信道冲突区域示意图，如图4所示，切换命令～切换完成阶段对应冲突区域1，切换完成～删除源小区阶段对应冲突区域2。在冲突区域1是终端设备向目标小区发送随机接入请求，冲突区域2是终端设备同时与目标小区和源小区进行连接和信号传输。这两个过程中传输的信号不同，产生冲突的上行信道也不同。
具体地，冲突区域1时，终端设备向目标小区请求随机接入，随机接入(random access,RA)过程是终端设备向系统请求接入，收到系统的响应并分配接入信道的过程，一般的数据传输必须在随机接入成功之后进行。随机接入时需要选择物理随机接入信道(physical random access channel，PRACH)资源。HO的随机接入一般为非竞争的随机接入，当随机接入前导码(preamble码)资源不足的时候，也有可能是基于竞争的随机接入，基于竞争的随机接入有两种方式：一是传统的4step方式，二是r16协议拟新增的2step方式。
非竞争的随机接入过程、竞争的4step随机接入过程和竞争的2step随机接入过程请参阅5A～图5C所示，在如图5A～图5C所示的随机接入过程示意图所示，其中上行信号包括基于非竞争的随机接入的“随机接入前导码(Random Access Preamble)”，即消息1(message1,msg1)，对应的信道为PRACH；基于竞争的4step随机接入的msg1，对应的信道为PRACH，“预定传输(Scheduled Transmission)”，即msg3，对应的信道为PUSCH；以及对“冲突解决(Contention Resolution)”，即msg4反馈的返回确认信号或错误则返回不确认信号(ACK/NACK)，对应的信道为PUCCH；以及msgA，对应的信道为PUCCH和PUSCH 信道。这些信道被统称为随机接入相关信道。在目标小区请求随机接入的过程中，终端设备与源小区保持连接，且通过与源小区的PUSCH上传控制信息和业务数据，通过PUCCH传送上行控制信息，通过SRS进行上行信道质量估计和相关参数测量。因此，目标小区的随机接入相关信道有可能与源小区的PUCCH/PUSCH/SRS信道冲突。
冲突区域2时，终端设备同时与目标小区和源小区保持连接，那么终端设备同时与两个小区通过PUSCH上传控制信息和业务数据，通过PUCCH传送性能控制信息，通过SRS进行上行信道质量估计和相关参数测量。因此目标小区的PUSCH、PUCCH或SRS与源小区的PUSCH、PUCCH或SRS可能发生冲突。以上内容描述了在冲突区域1和冲突区域2发送信号的过程中可能发生的上行信道冲突。在这样的前提下，信号的同步发送和异步发送同样会对信道冲突产生影响。同步场景下，不同小区之间的帧边界起始时间是同步对齐的，一般时分双工(time division duplexing，TDD)网络都是同步的；异步场景下，不同小区之间的帧边界起始时间不对齐，一般频分双工(frequency division duplexing，FDD)网络都是异步的；同步场景下的TDD网络，一般把SRS信道配置在S子帧上，而且SRS信道都是周期发射；DAPS切换过程中，源小区向目标小区请求切换时，如果把源小区的SRS配置信息告知目标小区，这样目标小区的配置的SRS可以避开源小区时的SRS信道。
因此同步与异步的信道冲突差别在于：
1,异步(通常是FDD异步)场景下SRS与其他信道的碰撞的概率更大；
2,同步场景下，一般没有SRS与其他信道的碰撞，FDD同步场景下可能有SRS与其他信道的碰撞。
综合上述描述，在冲突区域1和冲突区域2可能发生的上行信道冲突如表2所示：

302、若所述终端设备确定发生上行信道冲突，则对所述上行信道冲突进行优化处理。
终端设备与源小区和目标小区的上行信道发生冲突，需要进行优化处理。
可选的，对上行信道冲突进行优化处理包括：对上行信道冲突进行基于优先级的优化 处理。
通常情况下，终端设备进行通信小区切换，或者同时与两个小区建立连接时，两个小区的通信信息重要程度不同，那么在上行信道冲突的时候，可以基于优先级对上行信道冲突进行处理，即优先保证高优先级的上行信道中的信息发送，其次再考虑低优先级的上行信道中的信息发送。
可选的，对上行信道冲突进行基于优先级的优化处理，包括：对上行信道冲突进行优先级丢弃处理，优先级丢弃处理包括获取源小区的上行信道和目标小区的上行信道的优先级，并对优先级高的上行信道中的信号通过一路上行射频通道进行发送。
对上行信道冲突进行优先级丢弃处理，即是设定源小区和目标小区各个上行信道的优先级，当两个不同优先级的上行信道发生冲突时，对高优先级的信道发送的信息通过射频通道进行传输，对低优先级的上行信道发送的信息进行丢弃。
可选的，对上行信道冲突进行基于优先级的优化处理之前，方法还获取第一优先级，具体包括：获取目标小区的随机接入相关信道与源小区的PUSCH，PUCCH或SRS之间的第一优先级，其中第一优先级为：目标小区的随机接入相关信道>源小区的PUSCH、PUCCH或SRS，其中所述＞表示优先级高于。
采用优先级丢弃处理，首先要确定各个上行信道之间的优先级划分。基于上述描述可知，冲突区域1期间，目标小区的随机接入相关信道有可能与源小区的PUCCH/PUSCH/SRS信道冲突。其中，SRS，是上行探测参考信号，在NR中，SRS信道的作用包括：上行信道探测；支持上行非码本传输；上行波束管理；下行波束赋形；载波切换。如果丢弃SRS信道，可能导致基站调度性能恶化等严重后果，因此SRS信道具有较高的优先级。
具体地，随机接入相关信道与PUCCH/PUSCH/SRS信道的优先级设置如下：
A、同步场景
由前述描述可知，在同步场景下，终端设备可以根据获取到的源小区SRS配置参数有效避开与目标小区的随机接入相关信道的冲突，因此不用考虑两者的优先级。而源小区的PUSCH/PUCCH优先级都比目标小区的随机接入相关信道低，因此设置的优先级大小关系为：
目标小区的随机接入相关信道>源小区的PUSCH/PUCCH；
其中大于符号表示优先级高于，即目标小区的随机接入相关信道的优先级高于源小区的PUSCH或PUCCH。
B、异步场景
在异步场景下，由于不同小区之间的帧边界起始时间不对齐，目标小区的随机接入相关信道与源小区的PUSCH/PUCCH/SRS三个信道都有可能发生冲突，由于基站根据SRS信道评估上下行信道质量，如果drop SRS信道后，可能导致基站调度性能恶化等严重后果，因此源小区的SRS信道具有较高的优先级，可以有以下规则：
1、目标小区msg1,msgA选择发送资源时避开源小区的SRS信道；
2、目标小区的msg3优先级高于源小区的PUCCH/PUSCH/SRS
目标小区的msg1,msgA选择发送资源时，终端设备同样可以获取SRS的配置参数，然后有效避开SRS信道。而在目标小区的msg3选择发送资源时，其优先级高于源小区的 PUCCH、PUSCH或SRS。原因在于，msg3中包含终端设备的唯一标识，用来竞争目标小区接入资源，重要程度高。
或者，基于降低在目标小区上接入时延考虑，在另外的实施例中，也可以直接认为：目标小区的随机接入相关信道优先级高于源小区的PUCCH/PUSCH/SRS。
请参阅图6，图6为本申请实施例提供的一种冲突区域1异步场景上行信道冲突示意图，如图6所示，用户终端与源小区连接并通过上行信道PUCCH、PUSCH和SRS发送信号，与目标小区连接，并通过随机接入相关信道发送msg1和msg3，当msg1与PUCCH冲突时，msg1的优先级高，对msg1通过射频同道进行发送，丢弃PUCCH中的信息；同样的，msg3与SRS信道发生冲突，msg3的优先级高，对msg3通过射频同道进行发送，丢弃SRS中的信息。
在冲突区域2阶段，源小区和目标小区的上行信道都为PUSCH/PUCCH/SRS信道，都是有可能碰撞冲突的；具体如表3所示：
表3
场景 目标小区可能碰撞通道 源小区可能碰撞通道
TDD同步 PUSCH/PUCCH PUSCH/PUCCH
FDD同步 PUSCH/PUCCH/SRS PUSCH/PUCCH/SRS
FDD异步 PUSCH/PUCCH/SRS PUSCH/PUCCH/SRS
同样的，TDD同步场景下，终端设备可以根据获取到的源小区SRS配置参数有效避开所有与SRS相关的冲突。因此不用考虑SRS信道与其他信道的优先级。在FDD同步和FDD异步场景下，源小区和目标小区的PUSCH、PUCCH或SRS彼此间都可能发生冲突。PUCCH主要用于传送上行调度请求(scheduling request,SR)，ACK/NACK，非周期性信道状态信息(Aperiodic Channel State Information，A-CSI)或周期性信道状态信息(Periodic Channel State Information，P-CSI)，SR用于申请上行授权，ACK/NACK用于反馈PDSCH的解调信息。如果SR，ACK/NACK不能及时传输，直接影响链路性能，所以优先级上SR，ACK/NACK>A-CSI>P-CSI；简化讨论，分为两类，一类是上传SR/ACK/NACK信息的PUCCH，记为：PUCCH with SR/ACK/NACK，一类是上传除SR/ACK/NACK之外信息的PUCCH，记为：PUCCH without SR/ACK/NACK；前者比后者具有更高优先级。
PUSCH主要传送上行数据包，PUCCH和PUSCH可能随路，即PUCCH合并在PUSCH上一起发，因此PUSCH也可以分为两类，一类是PUSCH with ACK/NACK，一类是PUSCH without ACK/NACK；同理，前者比后者具有更高优先级。
DAPS切换场景下，如果终端设备成功在目标小区上接入，则上行数据业务仅在一个小区上，比如可能在目标小区PUSCH上发送；但是源小区上，数据库连接池(DataBase connection pool，DPCP)层有Control PDU(控制数据包)，所以还是存在PUSCH。具体地，目标小区和源小区可能发生的信道冲突如表4所示：
表4
Figure PCTCN2019109758-appb-000002
Figure PCTCN2019109758-appb-000003
其中，对表4的解读，以编号1一行为例，表示目标小区的SRS与源小区的SRS可能发生冲突，以编号7一行为例，表示目标小区上传SR/ACK/NACK信息的PUCCH，与源小区上传SR/ACK/NACK信息的PUCCH之间可能发生冲突。
总的来说，由于DAPS切换的首要任务就是保证向目标小区的成功切换，因此同等情况下，目标小区的信道优先级高于源小区。
具体情况下，表4中所有可能发生的信道冲突的优先级设置如下：
1-5：目标小区的SRS>源小区所有信道；
即目标小区的SRS优先级高于源小区所有信道的优先级。这样可以保证目标小区 SRS相关功能正常，同时保证目标小区的链路连接质量。
6：目标小区PUCCH with SR/ACK/NACK>源小区SRS；
即目标小区PUCCH with SR/ACK/NACK优先级高于源小区SRS。这样可以保证目标小区重要上行控制信号功能正常，同时保证目标小区的链路连接质量。
但是在双连接期间，如果发现目标小区质量迅速变差，源小区信号质量好于目标小区，也可以采用目标小区PUCCH with SR/ACK/NACK<源小区SRS的优先级；保证源小区SRS信号正常，将有助于提升目标小区切换可能失败情况下的源小区的链路质量7-10：目标小区PUCCH with SR/ACK/NACK>源小区PUCCH&PUSCH；这样保证目标小区重要上行控制信号功能正常，同时保证目标小区的链路连接质量。
11：目标小区PUCCH without SR/ACK/NACK<源小区SRS；
即目标小区PUCCH without SR/ACK/NACK优先级高于源小区SRS。这样可以通过牺牲目标小区不太重要的上行控制信号，但是保证了源小区SRS相关功能正常。
12：目标小区PUCCH without SR/ACK/NACK<源小区PUCCH with SR/ACK/NACK；
即目标小区PUCCH without SR/ACK/NACK优先级低于源小区PUCCH with SR/ACK/NACK，这样可以通过牺牲目标小区不太重要的上行控制信号，保证源小区高优先级控制信道功能正常。
13：目标小区PUCCH without SR/ACK/NACK>源小区PUCCH without SR/ACK/NACK；
即目标小区PUCCH without SR/ACK/NACK优先级高于源小区PUCCH without SR/ACK/NACK。同等情况下，目标小区的信道优先级高于源小区，可以保证目标小区成功切换。
14：目标小区PUCCH without SR/ACK/NACK<源小区PUSCH with ACK/NACK；
目标小区PUCCH without SR/ACK/NACK优先级低于源小区PUSCH with ACK/NACK。可以通过牺牲目标小区不太重要的上行控制信号，保证源小区含有高优先级控制信号的PUSCH信道的功能正常。
15：目标小区PUCCH without SR/ACK/NACK>源小区PUSCH without ACK/NACK；
即目标小区PUCCH without SR/ACK/NACK优先级高于源小区PUSCH without ACK/NACK。源小区的PUSCH主要发送DPCP的控制信令包，重要性不太高，保证目标小区的PUCCH without SR/ACK/NACK有助于保证目标小区成功切换。
但是在双连接期间，如果发现目标小区质量迅速变差，源小区信号质量好于目标小区，也可以采用PUCCH without SR/ACK/NACK<源小区PUSCH without ACK/NACK的优先级，将有助于提升目标小区切换可能失败情况下的源小区的PUSCH信道的质量。
16：目标小区PUSCH with ACK/NACK>源小区SRS；
即目标小区PUSCH with ACK/NACK优先级高于源小区SRS。这样可以保证目标小区包含重要上行控制信号的PUSCH信道功能正常，保证目标小区的链路连接质量。
但是在双连接期间，如果发现目标小区质量迅速变差，源小区信号质量好于目标小区，也可以采用目标小区PUSCH with SR/ACK/NACK<源小区SRS的优先级；保证源小区SRS信号正常，将有助于提升目标小区切换可能失败情况下的源小区的链路质量。
17-20：目标小区PUSCH with ACK/NACK>源小区PUCCH&PUSCH；
即目标小区PUSCH with ACK/NACK优先级高于源小区PUCCH&PUSCH。这样可以保证目标小区包含重要上行控制信号的PUSCH信道的功能正常，保证目标小区的链路连接质量。
21：目标小区PUSCH without ACK/NACK<源小区SRS；
即目标小区PUSCH without ACK/NACK优先级低于源小区SRS。可以通过牺牲目标小区承载上行数据业务的PUSCH信道，保证源小区SRS相关功能正常。
但是在双连接期间，如果发现源小区质量迅速变差，目标小区信号质量好于源小区，也可以采用目标小区PUSCH without ACK/NACK>源小区SRS的优先级；保证目标小区的链路质量。
22：目标小区PUSCH without ACK/NACK<源小区PUCCH with SR/ACK/NACK；
即目标小区PUSCH without ACK/NACK优先级低于源小区PUCCH with SR/ACK/NACK。这样可以通过牺牲目标小区承载上行数据业务的PUSCH信道，保证源小区高优先级控制信道功能正常。
但是在双连接期间，如果发现源小区质量迅速变差，目标小区信号质量好于源小区，也可以采用PUSCH without ACK/NACK>源小区PUCCH with SR/ACK/NACK的优先级；保证目标小区的链路质量。
23：目标小区PUSCH without ACK/NACK>源小区PUCCH without SR/ACK/NACK；
即目标小区PUSCH without ACK/NACK优先级高于源小区PUCCH without SR/ACK/NACK。这样可以在源小区不包含重要信令的情况下，保证目标小区的上行数据业务的传输，提升目标小区链路质量。
24：目标小区PUSCH without ACK/NACK<源小区PUSCH with ACK/NACK；
即目标小区PUSCH without ACK/NACK优先级低于源小区PUSCH with ACK/NACK。这样可以通过牺牲目标小区承载上行数据业务的PUSCH信道，保证源小区包含高优先级控制信号的PUSCH信道功能正常。
但是在双连接期间，如果发现源小区质量迅速变差，目标小区信号质量好于源小区，也可以采用PUSCH without ACK/NACK>源小区PUSCH with ACK/NACK的优先级；保证目标小区的链路质量。
25：目标小区PUSCH without ACK/NACK>源小区PUSCH without ACK/NACK；
即目标小区PUSCH without ACK/NACK优先级高于源小区PUSCH without ACK/NACK。同等情况下，目标小区的信道优先级高于源小区，保证目标小区成功切换。
以上为冲突区域2阶段目标小区和源小区的信道优先级设置。在确定优先级后，同样的，如果高优先级和低优先级的信道发生冲突，对高优先级信道中的信号通过射频通道进行发送，对低优先级信道中的信号进行丢弃。
在本申请实施例中，通过对上行信道冲突进行优先级丢弃处理，可以最大程度地保证高优先级信道的信息发送完整度和效率。同时，根据上述信道优先级确定过程可知，高优先级的信道发送的信息更重要，那么采用优先级丢弃处理也能保证重要信息的发送，降低信道冲突损失。
可选的，对上行信道冲突进行优化处理，包括：对上行信道冲突进行同时发送处理，同时发送处理包括对源小区的上行信道中的信号和目标小区的上行信道中的信号进行时域叠加获得叠加后信号，再通过一路上行射频通道发送叠加后信号。
除了上述通过优先级丢弃处理进行上行信道冲突优化之外，还可以通过同时发送处理进行上行信道冲突优化。即是对源小区的上行信道中的信号和目标小区的上行信道中的信号进行时域叠加获得叠加后信号，再通过一路上行射频通道发送叠加后信号。
通常情况下，在如表1中的带内非连续同步/异步，以及带间同步/异步场景下，两个BBP通道对应两个RF通道，源小区和目标小区的信号可以通过不同的RF通道分别收发，支持同时传输。请参阅图7，图7为本发明实施例提供的一种多路上行通道分别同时传输的示意图，如图7所示，在有多路RF通道的情况下，每一路BBP通道都能从对应的RF通道发送信号，没有上行发送通道的冲突的问题，但是存在上行总功率的约束:
Psourcecell+Ptargetcell＝Pcmax，
其中Psourcecell表示源小区上行信道发送功率，Ptargetcell表示目标小区上行信道发送功率，Pcmax表示终端设备的总功率或最大发射功率。
所以功率分配问题是多路RF场景下要解决的问题，具体如下：
A，按照优先级分配方案：
功率分配前，同样的，确定源小区和目标小区的上行通道的优先级，确定方法可以如上述内容描述。高优先级上行信道的功率为Phighpriority，低优先级上行信道的功率为Plowpriority，那么：
Phighpriority＝min(Phighpriority，Pcmax)；
Plowpriority＝Pcmax–Phighpriority；
即优先保证高优先级的上行信道信息在最大发射功率约束条件下进行发送，有可剩余的终端设备发射功率时，再发送低优先级上行信道信息。
B，高优先级信道保障方案
如上述内容描述，随机接入相关信道，SRS，PUCCH with SR/ACK/NACK，PUSCH with ACK/NACK等信道为高优先级信道；如果它们之间同时传输，则放开终端设备的总功率约束：
Phighpriority＝min(Phighpriority，Pcmax)；
Plowpriority＝min(Plowpriority，Pcmax)。
C，性能优先方案
在源小区和目标小区双连接期间，由于双连接持续时间较短，放开所述期间所有信道的总功率限制；功率分配前，两个小区计算出的上行信道功率分别为Psource，Ptarget，那么：
Psource＝min(Psource，Pcmax)；
Ptarget＝min(Ptarget，Pcmax)；
即是说，不考虑信道优先级的问题，以两个信道都以能发送信息为重点考虑。
在如表1所述的同频同步/异步，以及带内连续的异频同步/异步场景下，两个BBP通 道对应一个RF通道，请参阅图8，图8为本申请实施例提供的一种多路上行通道通过一路射频通道同时发送的示意图，如图8所示，在这种场景下进行的同时发送处理，即是时域累加两路信号，然后再通过一路RF通道一起发送出去。本申请实施例中涉及的同时发送处理即时这种处理方法。
同样的，在这种场景下的同时发送处理，终端设备的总功率是固定的，因此，通过这种同时发送处理也涉及到终端设备总功率Pcmax的约束。
可选的，在对上行信道冲突进行同时发送处理之前，方法还包括：计算获取源小区的上行信道和目标小区的上行信道之间的第一功率差值；确定第一功率差值小于第二门限值。
首先，将两路上行信道中的信号通过时域叠加后进行发送，如果两路信号功率差值过大，会有较多的负面效果。因此，在两路上行信道之间的第一功率差值不满足小于第二门限值的情况下，不能采用同时发送处理方法解决上行信道冲突，可以采用其他方式处理，例如优先级丢弃处理。如果第一功率差值小于第二门限值，则可以进行下一步判定，确定是否可以对上行信道进行同时发送处理。
两路信号时域相加，会导致峰值平均功率比(Peak to average power ratio,PAPR，简称峰均比)增加；PAPR会影响功率放大器(Power amplifier,PA)的线性工作区间，引入最大发射功率降低(Maximum Power Reduction，MPR)来解决PAPR问题：不同的情况下允许终端设备回退一定的功率(即对终端设备总功率值减去MPR值)，避免PA工作进入非线性区间。
以两种不同调制的信号为例，相比于离散傅里叶变换扩频正交频分复用(Discrete Fourier transform spread spectrum orthogonal frequency division multiplexing，DFT-s-OFDM)，循环正交频分复用(Cyclic prefix orthogonal frequency division multiplexing,CP-OFDM)有更大的PAPR，因此也有更大的MPR。两个时域信道叠加，例如DFT-s-OFDM叠加，叠加后的PAPR大于一路DFT-s-OFDM的PRPA，因此需要更多的MPR。
从上述描述可知，时域叠加发送信号时终端设备的MPR可能增大，可知同时发送处理时的MPR大于或等于优先级丢弃处理时的MPR。同时发送处理时的终端设备的总功率(记为Pcmax_2t)小于优先级丢弃处理时的终端设备的总功率(记为Pcmax_1t)，那么优先级丢弃处理时高优先级信道的实际发送功率P_highPriority_1t和同时发送处理时同一高优先级信道的实际发送功率P_highPriority_2t的确定过程分别如下：
P_highPriority_1t＝min(Pcmax_1t，P_highPriority)；
P_highPriority_2t＝min(Pcmax_2t，P_highPriority)；
其中P_highPriority表示高优先级信道的计算所需发送功率。
在判断是否对上行信道冲突进行同时发送处理前，也要进行上行信道的优先级确定。然后确定高优先级信道的信号进行发送时实际能发送功率。当同时发送处理时，P_highPriority_1t和P_highPriority_2t分别为优先级丢弃处理和同时发送处理两个情况下实际能发送的功率。一般来说，由于同时发送的MPR较大，P_highPriority_1t＞＝P_highPriority_2t。第二功率差值＝P_highPriority_1t-P_highPriority_2t，当第二功率差值>第三门限值；说明上行信道冲突进行同时发送处理损失太大，不能进行同时发送处理，可以采用其他方法解决上行信道冲突，例如优先级丢弃处理。如果第二功率差值≤第三门限值， 可以采用同时发送处理。
可选的，在计算获取进行同时发送处理时高优先级信道的实际发送功率P_highPriority_2t之前，所述方法还包括：确定所述叠加后信号的分配方式，所述分配方式包括几乎连续分配方式和非连续分配方式，所述几乎连续的分配方式特征至少有所述源小区和所述目标小区分配的频点中的最高频点和最低频点之间，未分配的频段与总频段之间的比例小于第一门限值；当所述分配方式为几乎连续分配方式时，获取所述射频通道的第一最大功率回退MPR1，并根据所述MPR1计算获取所述Pcmax_2t；当所述分配方式为非连续分配方式时，获取所述射频通道的第二最大功率回退MPR2，并根据所述MPR2计算获取所述Pcmax_2t。
在本发明实施例中，两个小区的信道冲突同时发送处理情况下的几乎连续分配至少满足：
N RB_gap/(N RB_alloc+N RB_gap)≤第一门限值
其中N RB_gap为两个小区总计分配的频段之间没有分配给任一小区的频段；N RB_alloc为两个小区总计分配频段之间已经分配给任一小区的频段；第一门限值是一个待定的值。
如果基站调度满足上述几乎连续分配方式的要求；则可以减少PAPR，提升同时传输的性能。由于基站的资源分配时，PUCCH一般固定在某些频率资源，通过基站之间的信息交互，目标小区和源小区能相互知悉对方的PUCCH频率资源，因此至少可以达成以下情况下的几乎连续分配：
目标小区随机接入相关信道和源小区的PUCCH码道分配尽可能相邻；
目标小区的PUCCH和源小区的PUSCH的分配尽可能相邻；
源小区的PUCCH和目标小区的PUSCH分配尽可能相邻。
请参阅图9，图9为本申请实施例提供的一种几乎连续分配方式示意图，如图9所示，源小区的PUCCH与目标小区的msg3分配的频段之间的间隔非常小，其中源小区的PUCCH的最低频点为f1，最高频点为f2，目标小区的msg3的最低频点为f3，最高频点为f4，f1～f4之间可以连续分配、重叠分配或间隔分配，在图9中为间隔分配，已分配的频段NRB_alloc＝(f2-f1)+(f4-f3)，未分配的频段NRB_gap＝f3-f2，其中：
NRB_gap/(NRB_alloc+NRB_gap)＝(f3-f2)/((f2-f1)+(f4-f3)+(f3-f2))＝(f3-f2)/(f4-f1)；
(f3-f2)/(f4-f1)≤第一门限值；
如果终端设备对源小区和目标小区进行时域重叠时分配的时频资源符合几乎连续分配的要求，按照几乎非连续分配方式对应的方法计算获得终端设备的第一最大功率回退值MPR1；如果网络分配的时频资源不符合几乎连续分配的要求，按照非连续分配方式计算获得终端设备的第二最大功率回退值MPR2。一般来说，MPR1＜MPR2。
在上述计算获取P_highPriority_2t的过程中，当MPR越大时，P_highPriority_2t越小，造成第二功率差值增大，进行同时发送处理的损失也就越大。为了减小这种损失，多路上行通道中的信号进行时域叠加时应该尽量满足几乎连续的分配方式。
在本申请实施例中，对上行信道冲突进行同时发送处理，在码道冲突且有功率富裕的情况下，可以同时发送两路信道，不需要丢弃一路信号，保证了多路信号发送的完整性。
在本申请实施例中，当终端设备与源小区已建立连接关系，且向目标小区发送连接请求或建立连接关系时，终端设备检测是否发生上行信道冲突，上行信道包括源小区的上行信道和目标小区的上行信道；若终端设备确定发生上行信道冲突，则对上行信道冲突进行优化处理。这个过程中，由于终端设备与一个小区建立了连接的同时向另一个小区发起连接，或者同时连接了两个小区，导致上行信道可能发生冲突，终端设备检测冲突并对冲突进行解决，可以减少上行信道的信息损失，提升上行信道发送信息的效率。
参见图10，图10为本发明实施例提供的另一种信道冲突处理方法流程示意图。如图10所示，该方法包括：
401、当所述终端设备与源小区建立连接关系，且在所述终端设备向目标小区发起接入请求后，在所述目标小区接入成功前，检测所述目标小区的随机接入相关信道与所述源小区的上行共享信道PUSCH，上行控制信道PUCCH或探测参考信道SRS之间是否发生符号级冲突，所述随机接入相关信道包括物理随机接入信道PRACH、发送msg3的PUSCH、用于msg4上行ACK/NACK反馈的PUCCH或用于发送msgA信号的PUCCH或PUSCH；若是，则执行步骤403；
402、当所述终端设备与源小区建立连接关系，且在所述目标小区接入成功后，在所述终端设备断开与所述源小区的连接前，检测所述目标小区的PUSCH、PUCCH或SRS与所述源小区的PUSCH、PUCCH或SRS之间是否发生符号级冲突，若是，执行步骤404；
在步骤401和步骤402中，表明终端设备与目标小区处于不同的连接状态，那么源小区与目标小区可能发生的上行信道冲突也会有所区别。因此，终端设备需要检测不同的可能发生冲突的上行信道，发现存在的冲突。
403、获取所述目标小区的随机接入相关信道与所述源小区的PUSCH，PUCCH或SRS之间的第一优先级，执行步骤405；
404、获取所述目标小区的PUSCH、PUCCH或SRS与所述源小区的PUSCH、PUCCH或SRS之间的第二优先级，执行步骤405；
因为上行信道冲突不同，其对应的优先级也会有所区别，根据不同的优先级结果，对发生冲突的上行信道进行处理，以便完成最终的信息发送。
405、对所述上行信道冲突进行优先级丢弃处理。
其中，上述401-405的其他具体描述可以参照步骤301-302所描述的上行冲突处理方法相应描述，在此不再赘述。
可见，在本申请实施例中，通过对上行信道冲突进行优先级丢弃处理，可以最大程度地保证高优先级信道的信息发送完整度和效率。同时，根据上述信道优先级确定过程可知，高优先级的信道发送的信息更重要，那么采用优先级丢弃处理也能保证重要信息的发送，降低信道冲突损失。
参见图11，图11为本发明实施例提供的另一种信道冲突处理方法流程示意图。如图11所示，该方法包括：
501、当所述终端设备与源小区建立连接关系，且向所述目标小区发送连接请求或建立 连接关系时，所述终端设备检测是否发生上行信道冲突，所述上行信道包括所述源小区的上行信道和所述目标小区的上行信道；
502、若所述终端设备确定发生上行信道冲突，计算获取所述源小区的上行信道和所述目标小区的上行信道之间的第一功率差值；
503、若所述第一功率差值小于第二门限值，执行步骤504；
因为在进行同时发送处理时，不同功率的信号进行叠加，如果两者之间的功率差值过大，会造成较小功率的一路上行信号损失过大，而如果损失过大的一路上行信号中包含重要信息，则可能造成较严重的后果。因此，首先需要确定源小区的上行信道和目标小区的上行信道之间的第一功率差值小于第二门限值，才能进一步考虑是否进行同时发送处理。
504、获取所述目标小区的随机接入相关信道与所述源小区的PUSCH，PUCCH或SRS之间的第一优先级，以及所述目标小区的PUSCH、PUCCH或SRS与所述源小区的PUSCH、PUCCH或SRS之间的第二优先级；
505、分别计算获取进行优先级丢弃处理时高优先级信道的实际发送功率P_highPriority_1t和进行同时发送处理时高优先级信道的实际发送功率P_highPriority_2t；
同样的，同时发送处理时也可以优先保证高优先级上行信道中的信息发送。因此，计算高优先级信道在同时发送处理情况下和单独发送情况下对应的实际发送功率，然后通过计算单独发送情况下高优先级上行信道对应的实际发送功率和同时发送处理情况下高优先级信道的实际发送功率的功率差值是否小于第二功率值，判定高优先级信道中的信号损失是否在可接受范围内，最终确定是否采用同时发送处理。
506、计算获取P_highPriority_1t与P_highPriority_2t之间的第二功率差值；
507、若确定所述第二功率差值小于第三门限值，执行步骤508；
508、对所述上行信道冲突进行同时发送处理。
其中，上述501-508的其他具体描述可以参照步骤301-302所描述的上行冲突处理方法相应描述，在此不再赘述。
可见，在本申请实施例中，对上行信道冲突进行同时发送处理，在码道冲突且有功率富裕的情况下，可以同时发送两路信道，不需要丢弃一路信号，保证了多路信号发送的完整性。
