Description

一种功率控制方法及装置、终端、网络设备 技术领域
本申请实施例涉及移动通信技术领域，具体涉及一种功率控制方法及装置、终端、网络设备。
背景技术
在随机接入过程中，终端对于前导码(preamble)的发送不能一开始就用很大的上行发射功率，目的是为了避免上行干扰。终端在对preamble重传时，要进行功率攀升来发送preamble。
在新无线非授权(New Radio-Unlicense，NR-U)系统中，在NR-U小区中发起随机接入过程，无论是基于竞争的随机接入过程还是基于非竞争的随机接入过程，由于信道抢占不成功，所以存在基站已经检测到preamble，但是mgs2发送不下来的可能，所以终端在现有的随机接入响应(Random Access Response，RAR)接收窗口内等不到RAR。但是终端并不清楚是由于信道抢占不成功导致的RAR接收失败，还是由于自己功率低导致的RAR接收失败，所以终端不清楚是否要进行功率攀升。
发明内容

本申请实施例提供的功率控制方法，包括：
终端基于第一信息和第二信息，确定重传前导码所采用的功率；所述第二信息包括以下至少之一：第一物理下行控制信道(Physical Downlink Control Channel，PDCCH)、所述第一PDCCH调度的第一随机接入响应；
其中，所述第一信息用于指示所述基站抢占信道成功，所述第一PDCCH通过第一随机接入无线网络临时标识(Random Access-Radio Network Temporary Identifier，RA-RNTI)加扰。
本申请实施例提供的功率控制方法，包括：
基站接收终端发送的前导码后进行信道抢占，如果抢占信道成功，则所述基站向所述终端发送第一信息、第一PDCCH以及所述第一PDCCH调度的第一随机接入响应；
其中，所述第一信息用于指示所述基站抢占信道成功，所述第一PDCCH通过第一RA-RNTI加扰。

功率控制单元，用于基于第一信息和第二信息，确定重传前导码所采用的功率；所述第二信息包括以下至少之一：第一PDCCH、所述第一PDCCH调度的第一随机接入响应；
其中，所述第一信息用于指示所述基站抢占信道成功，所述第一PDCCH通过第一RA-RNTI加扰。
本申请实施例提供的功率控制装置，包括：
信道检测单元，用于接收终端发送的前导码后进行信道抢占；
发送单元，用于如果抢占信道成功，则向所述终端发送第一信息、第一PDCCH以及所述第一PDCCH调度的第一随机接入响应；
其中，所述第一信息用于指示所述基站抢占信道成功，所述第一PDCCH通过第一RA-RNTI加扰。
本申请实施例提供的终端，包括处理器和存储器。该存储器用于存储计算机程序，该处理器用于调用并运行该存储器中存储的计算机程序，执行上述的功率控制方法。
本申请实施例提供的网络设备，包括处理器和存储器。该存储器用于存储计算机程序，该处理器用于调用并运行该存储器中存储的计算机程序，执行上述的功率控制方法。
本申请实施例提供的芯片，用于实现上述的功率控制方法。
具体地，该芯片包括：处理器，用于从存储器中调用并运行计算机程序，使得安装有该芯片的设备执行上述的功率控制方法。
本申请实施例提供的计算机可读存储介质，用于存储计算机程序，该计算机程序使得计算机执行上述的功率控制方法。
本申请实施例提供的计算机程序产品，包括计算机程序指令，该计算机程序指令使得计算机执行上述的功率控制方法。
本申请实施例提供的计算机程序，当其在计算机上运行时，使得计算机执行上述的功率控制方法。
通过上述技术方案，通过指示基站抢占信道成功的第一信息来辅助终端判决是否进行功率攀升来重发前导码，进一步，所述第一信息可以是新定义的RNTI加扰的PDCCH或者是信道抢占成功指示信号，从而可以避免基站抢占信道失败的情况下还依然进行功率攀升来重发前导码，降低了系统的上行干扰。

为便于理解本申请实施例的技术方案，以下对本申请实施例相关的技术概念进行说明。
NR工作在非授权频段，包括如下几种工作场景：
1)载波聚合场景：主小区(Primary Cell，PCell)为授权频谱，通过载波聚合方式聚合工作在非授权频谱上的辅小区(Secondary Cell，SCell)。
2)双连接工作场景：PCell为LTE授权频谱，主辅小区(Primary Secondary cell，PScell)为NR非授权频谱。
3)独立工作场景：NR作为一个独立小区工作在非授权频谱。
一般来说，NR-U的工作频带(Band)为5GHz非授权频谱和6GHz非授权频谱；在非授权频谱上，NR-U的设计应该保证与其他已经工作在这些非授权频谱上的系统之间的公平性。公平性的原则是，NR-U对于已经部署在非授权频谱上的系统的影响不能超过这些系统之间的影响。
为了保证在非授权频谱上各系统之间的公平性共存，能量检测已经被同意作为一个基本的共存机制。一般的能量检测机制为先听后说(Listen Before Talk，LBT)机制，该机制的基本原理为，基站或者终端(传输端)在非授权频谱上传输数据之前，需要先按照规定侦听一段时间。如果侦听的结果表示该信道为空闲状态，则传输端可以给接收端传输数据。如果侦听的结果表示该信道为占用状态，则传输端需要根据规定回退一段时间再继续侦听信道，知道信道侦听结果为空闲状态，才能向接收端传输数据。
对于下行数据传输，在非授权频段上，基站需要执行LBT；在LAA中，信道接入的优先级由如下表1决定：
Figure PCTCN2019079751-appb-000001
表1
其中，Mp与执行信道接入的侦听信道时间有关系。具体的，基站需要先执行Td时间的信道侦听，其中Td＝16us+Mp×9us。
CWmin，p和CWmax，p与信道接入过程中的随机侦听信道时间有关系。具体的，在基站侦听Td时间信道为空闲时，需要再侦听N次信道，每次时长为9us。其中N为一个从0到CWp之间的随机数，而CW min,p≤CW p≤CW max,p。
Tmcot，p为基站抢占到信道之后，占用信道的最长时间，它与基站采用的信道优 先级有关系，比如优先级为1，则信道侦听成功之后，最多占用信道2ms。
综上，对于UE侧来讲，基站给UE传输数据需要在MCOT时间之内，如果基站没有抢占到信道，也就是在MCOT时间之外，UE是不会收到基站给UE的调度数据的。
随机接入是UE与网络侧建立无线连接的重要过程，通过随机接入可以与基站之间取得上行同步，申请上行资源。随机接入过程分为竞争随机接入和非竞争随机接入。图2给出了一种竞争随机接入过程的流程，如图2所示，竞争随机接入过程包括以下步骤：
步骤201：终端向基站发送msg1。
这里，终端向基站发送msg1具体可以通过以下过程来实现：
–终端确定同步信号块(Synchronization Signal Block，SSB)与PRACH资源的关系(由高层配置)；
–终端接收一组SSB并确定其参考信号接收功率(Reference Signal Received Power，RSRP)值，根据门限选择合适的SSB；
–终端基于选择的SSB和SSB与RACH资源的对应关系确定PRACH资源；
–终端根据msg3的大小选择前导码组(preamble group)，进一步选择前导码；
–终端设置前导码的目标接收功率；
–终端在PRACH时频域资源上发送前导码。
步骤202：终端接收基站发送的msg2。
这里，终端接收基站发送的msg2具体可以通过以下过程来实现：
–终端根据发送msg1的PRACH时频域资源确定随机接入无线网络临时标识(Random Access-Radio Network Temporary Identifier，RA-RNTI)；
–终端在发送了前导码之后的第一个物理下行控制信道(Physical Downlink Control Channel，PDCCH)时机(occasion)开启RAR窗口(ra-Response Window)并在该窗口运行期间监听PDCCH，以接收对应RA-RNTI的RAR；
–如果在RAR窗口内没有收到RAR，则终端进行msg1的重传；
–如果在RAR窗口内收到RAR，则终端根据RAR的指示进行msg3的传输。
步骤203：终端向基站发送msg3。
这里，终端向基站发送msg3具体可以通过以下过程来实现：
–终端基于RAR中的上行调度(UL Grant)传输msg3；
–当Msg3传输后，启动ra-ContentionResolutionTimer并在定时器运行期间监听PDCCH；当Msg3进行重传时，重启该定时器；在该定时器超时或停止之前，终端会一直监听PDCCH。
步骤204：终端接收基站发送的msg4。
这里，如果终端收到小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)扰码的DCI format 1_0及其对应的PDSCH，随机接入完成；如果终端收到临时小区无线网络临时标识(Temporary Cell-Radio Network Temporary Identifier，TC-RNTI)扰码的DCI format 1_0及其对应的PDSCH，并比对内容成功，随机接入完成。
在NR-U小区中发起随机接入过程，无论是竞争随机接入还是非竞争随机接入，由于信道抢占不成功，所以存在基站已经检测到preamble，但是mgs2发送不下来的可能，所以终端在RAR接收窗口内等不到RAR。但是终端并不清楚是由于信道抢占不成功导致的RAR接收失败，还是由于自己功率低导致的RAR接收失败，为了使终端明确重传前导码所采用的功率，提出了本申请实施例的以下技术方案。
图3为本申请实施例提供的功率控制方法的流程示意图，如图3所示，所述功率控制方法包括以下步骤：
步骤301：基站接收终端发送的前导码后进行信道抢占，如果抢占信道成功，则所述基站向所述终端发送第一信息、第一PDCCH以及所述第一PDCCH调度的第一随机接入响应；其中，所述第一信息用于指示所述基站抢占信道成功，所述第一PDCCH通过第一RA-RNTI加扰。
本申请实施例的技术方案可以应用于任意类型的随机接入过程，例如竞争随机接入过程(如图2所示)或非竞争随机接入过程。需要说明的是，非竞争随机接入过程相对于竞争随机接入过程而言，由于不需要解决随机接入冲突(网络侧预先配置了没有冲突的随机接入资源)，因此，非竞争随机接入过程只包含msg1传输和mgs2传输两个步骤。其中，msg1传输是指终端在PRACH上发送前导码(preamble)，msg2传输是指基站发送RAR。
本申请实施例中提到的基站包括但不限于是LTE基站(eNB)，NR基站(gNB。)
本申请实施例中提到的终端可以是手机、笔记本、平板电脑、车载终端、可穿戴式终端等任意能够与网络进行通信的设备。
在本申请的一种实施方式中，所述第一信息为第一RNTI加扰的第二PDCCH。需要说明的是，所述第一RNTI与所述第一RA-RNTI不同，所述第一RA-RNTI为所述终端发送前导码的PRACH资源对应的RA-RNTI。所述第一RNTI是新定义的RNTI，该RNTI可以是系统唯一或者网络侧配置。
在本申请的另一种实施方式中，所述第一信息为信道抢占成功指示信号。
需要说明的是，如果基站抢占信道失败，则不会向所述终端发送第一信息。
步骤302：终端基于第一信息和第二信息，确定重传前导码所采用的功率；所述第二信息包括以下至少之一：第一PDCCH、所述第一PDCCH调度的第一随机接入响应。
本申请实施例中，所述终端基于对第一信息和第二信息的检测结果，确定重传前导码所采用的功率，可以有以下两种应用场景：
场景一：所述第一信息为第一RNTI加扰的第二PDCCH
1.1)如果所述终端检测到所述第二PDCCH，未检测到所述第一PDCCH，则所述终端增大前导码的发射功率后对前导码进行重传；
1.2)如果所述终端检测到所述第二PDCCH，未检测到所述第一PDCCH调度的第一随机接入响应，则终端增大前导码的发射功率后对该前导码进行重传；所述第一随机接入响应是指所述终端发送的前导码的标识对应的随机接入响应，所述第一RA-RNTI为所述终端发送前导码的物理随机接入信道PRACH资源对应的RA-RNTI；
1.3)如果所述终端未检测到所述第二PDCCH，则所述终端维持前导码的发射功率不变对前导码进行重传。
举个例子：在基于竞争的随机接入过程中，终端选择PRACH资源和preamble，并在该PRACH资源上发送preamble；终端基于PRACH资源计算RA-RNTI，并启动时间窗口等待RAR。基站接收preamble，进行信道抢占，如果信道抢占成功，则基站发送X-RNTI(即第一RNTI)加扰的PDCCH(即第二PDCCH)，同时发送RA-RNTI加扰的PDCCH(即第一PDCCH)。如果信道抢占不成功，则基站放弃该RAR的发送，并丢弃该RAR。终端检测X-RNTI加扰的PDCCH，同时检测RA-RNTI加扰的PDCCH，针对检测结果有如下几种行为：
行为1：如果检测到X-RNTI加扰的PDCCH，没有检测到RA-RNTI加扰的PDCCH，则终端进行功率攀升，继续发送preamble；或者，如果检测到X-RNTI加扰的PDCCH，没有检测到终端发送preamble对应的随机接入前导码标识(Random Access preamble ID，RAPID)对应的RAR，则终端进行功率攀升，继续发送preamble。
行为2：如果没有检测到X-RNTI加扰的PDCCH，则终端继续发送preamble，但不 进行功率攀升。
行为3：如果检测到终端发送preamble对应的RAPID对应的RAR，则终端从RAR中获取上行授权(UL grant)，利用该UL grant发送msg3。
场景二：所述第一信息为信道抢占成功指示信号
2.1)如果所述终端检测到所述信道抢占成功指示信号，未检测到所述第一PDCCH，则所述终端增大前导码的发射功率后对前导码进行重传；
2.2)如果所述终端检测到所述信道抢占成功指示信号，未检测所述第一PDCCH调度的第一随机接入响应，则终端增大前导码的发射功率后对该前导码进行重传；所述第一随机接入响应是指所述终端发送的前导码的标识对应的随机接入响应，所述第一RA-RNTI为所述终端发送前导码的PRACH资源对应的RA-RNTI；
2.3)如果所述终端未检测到所述为信道抢占成功指示信号，则所述终端维持前导码的发射功率不变对前导码进行重传。
举个例子：定义一个信号，当基站抢占信道成功就会发送该信号，该信号可以称为信道抢占成功指示信号。任何终端都可以检测到信道抢占成功指示信号。在基于竞争的随机接入过程中，终端选择PRACH资源和preamble，并在该PRACH资源上发送preamble；终端基于PRACH资源计算RA-RNTI，并启动时间窗口等待RAR。基站接收preamble，进行信道抢占，如果信道抢占成功，则基站发送信道抢占成功指示信号，同时发送RA-RNTI加扰的PDCCH(即第一PDCCH)。如果信道抢占不成功，则基站放弃该RAR的发送，并丢弃该RAR。终端检测信道抢占成功指示信号，同时检测RA-RNTI加扰的PDCCH，针对检测结果有如下几种行为：
行为1：如果终端检测到信道抢占成功指示信号，没有检测到RA-RNTI加扰的PDCCH，则终端进行功率攀升，继续发送preamble；或者，如果终端检测到信道抢占成功指示信号，没有检测到终端发送preamble对应的RAPID对应的RAR，则终端进行功率攀升，继续发送preamble。
行为2：如果没有检测到信道抢占成功指示信号，则终端继续发送preamble，但不进行功率攀升。
行为3：如果检测到终端发送preamble对应的RAPID对应的RAR，则终端从RAR中获取UL grant，利用该UL grant发送msg3。
