Description

激活辅小区的方法、通信装置和网络设备 技术领域
本申请涉及通信领域，更为具体的，涉及通信领域中激活辅小区的方法、通信装置和网络设备。
背景技术
在无线网络通信中，对于一个用户设备(user equipment，UE)而言，主小区(primary cell，PCell)是工作在主频带上的小区。UE在某一个小区进行初始连接建立过程，或开始连接重建立过程中，该小区被指示为主小区。辅小区(secondary cell，SCell)是工作在辅频带上的小区。在初始安全激活流程(initial security activation procedure)之后，通过无线资源控制(radio resource control，RRC)连接重配置消息添加/修改/释放的。一旦RRC连接建立，辅小区就可能被配置以提供额外的无线资源。
目前在辅小区激活的过程中，终端设备先收到网络设备发送的RRC连接重配置消息，如果RRC连接重配置消息里面包含辅小区添加信令，那么终端设备就将该RRC连接配置消息中的载波添加为辅小区。之后，终端设备接收到辅小区的激活命令，表示激活过程开始。在终端设备完成硬件准备工作后，即激活过程完成后，会向网络设备发送上行(uplink，UL)信号，用于通知网络设备该辅小区激活成功。网络设备正确接收到该上行信号后，会向该终端设备发送调度命令(信令或数据)，该信令或数据用于通知该终端设备进行数据的接收或者发送。此后，该上行信号将继续按照RRC连接重配置消息中配置信息发送。或者，在没有给终端设备配置发送该上行信号的资源或者配置的该上行信号的发送周期较大时，网络设备会在系统配置的最大激活时间的时间到来后，也会向终端设备发送信令或数据。上行信号的发送周期较长时，激活时延较大。上行信号的发送周期较短时，发送上行信号的网络资源的消耗较大。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)等。
本申请实施例中的通信装置可以指终端设备、用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、通信装置、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通讯(global system of mobile communication，GSM)系统或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站(nodeb，NB)，还可以是LTE系统中的演进型基站(evolutional nodeb，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
对于一个终端设备而言，主小区是工作在主频带(主载波)上的小区，辅小区是工作在辅频带(辅载波)上的小区。该终端设备的服务小区(serving cell)可以是一个辅小区，也可以是一个主小区。对于没有配置载波聚合(carrier aggregation，CA)的终端设备而言，只有一个服务小区，即主小区。对于配置了CA的终端设备而言，服务小区是由主小区和辅小区组成的小区集合。配置了CA的终端设备与1个主小区和最多的4个辅小区相连。图1是不同的载波聚合模式的示意图。在图1中，对于终端设备A，不支持CA，因此只有一个小区，即有一个上行载波和一个下行载波。对于终端设备B，配置了对称的CA模式，聚合了两个载波，同时支持两个上行载波和下行载波。对于终端设备C，配置了不对称的CA模式，有3个下行载波和1个上行载波。在载波聚合模式下，一个终端设备支持 的下行载波的个数大于或者等于上行载波的个数。目前，载波聚合可以最大支持32个载波的聚合，在未来的5G网络中，载波聚合可能支持更多的载波，即终端设备需要增加(激活)的辅小区更多。
图2是现有技术中激活辅小区的示意性流程图。终端设备首先会接收到RRC重配置消息，在接收到该RRC重配置消息后，如果里边包含SCell添加信令，那么UE将把配置消息中的载波添加为辅小区所在的载波。但是该辅小区处于非激活状态，在非激活状态下，终端设备在这个辅小区上不发送上行信号，例如，探测参考信号(sounding reference signal，SRS)；不在该辅小区上发送UL数据；不发送该辅小区的信道质量指示(channel quality indicator，CQI)/预编码矩阵指示(pre-coding matrix indicator，PMI)/秩指示(rank indication，RI)；不侦听这个辅小区的物理下行控制信道(physical downlink control channel，PDCCH)，包括在这个辅小区上的调度以及调度这个辅小区的控制信道；不执行随机接入过程；如果配置了物理上行控制信道(physical uplink control channel，PUCCH)，不在物理上行控制信道(physical uplink control channel，PUCCH)上传输。不在这个辅小区的上行共享信道(uplink shared channel)发送数据。如图2所示，终端设备在第T时间单元接收到该辅小区的激活命令，在之后的4ms内，完成激活命令的接收和相关的解码等处理过程。在第T+8时间单元后会向网络设备发一个有效的信道状态信息(channel state information，CSI)，用于向网络设备报告目前小区的信道状态。在第T+8至第T+k时间单元之间，如果终端设备完成了硬件准备工作，例如，锁相环调整、晶振调整、自动增益控制、射频链激活等，在完成硬件准备工作后，即辅小区激活完成后，会向网络设备周期性的发送上行信号，用于通知网络设备该辅小区激活成功。例如，该上行信号包括CSI和/或SRS。网络设备收到该上行信号的时间可能早于第T+k时间单元，也可能晚于第T+k时间单元，其中k的值为24或34，当k的值为24时，表明要激活的辅小区已经上报过有效的测量报告，当k的值为34时，表明要激活的辅小区之前没有上报过有效的测量报告。K的值为系统配置的最大激活时间，即到第T+k时间单元时，即使网络设备没有正确接收到该上行信号，也会向终端设备发送调度命令(信令或者数据)，用于调度该终端设备进行数据的接收或者发送。该最长激活时间为协议规定或预定义的，是指该终端设备接收到该激活命令后，到该终端设备激活所用的最长时间，例如3GPP 36.133中定义的n+24毫秒或n+34毫秒。
因此，网络设备在接收到该上行信号，或者到达第T+k时间单元，这两个条件中只要满足任意一个，网络设备就会认为这个终端设备的辅小区已激活，并开始执行数据调度。在终端设备接收到调度命令后，终端设备继续按照配置的周期发送上行信号，向网络设备发送该辅小区的CQI/PMI/RI/，侦听这个辅小区的PDCCH，和/或在PUCCH上发送数据，以及打开其他辅小区的去激活计时器，触发该辅小区的功率余量上报动作等。
现有的辅小区激活过程中，当配置的上行信号的发送周期较长或者没有配置上行信号的资源时，网络设备只能等到配置的最大激活时间的时间到达后(即到达第T+K时间单元)才能调度该终端设备的辅小区。这样会造成调度时延。而当配置的上行信号的发送周期较短时，在辅小区激活后，由于还是按照原有的周期发送上行信号，会造成比较严重的网络资源消耗。
基于上述问题，本发明实施例提供了一种激活辅小区的方法，可以解决在辅小区激活 过程中，网络资源消耗和激活时延不平衡的问题，提高数据传输效率和用户体验。
应理解，对于5G或新型无线接入网络(new radio access network，NR)系统，在一个NR基站(NR-NB)下，可能存在一个或多个发送接收点(transmission reception point，TRP)，所有的TRP属于同一个小区。其中，每个TRP和终端设备都可以使用本申请实施例的激活辅小区的方法。在另一种场景下，网络设备还可以分为控制单元(control unit，CU)和数据单元(data unit，DU)，在一个CU下，可以存在多个DU，其中，每个DU和终端设备都可以使用本申请实施例的激活辅小区的方法。CU-DU分离场景和多TRP场景的区别在于，TRP只是一个射频单元或一个天线设备，而DU中可以实现协议栈功能，例如DU中可以实现物理层功能。
图3是本发明实施例一个典型的应用场景的示意图，如图3所示，本申请的技术方案可以应用在网络设备与终端设备之间进行辅小区激活过程中。终端设备1和终端设备2的服务小区来自同一个网络设备，终端设备1和终端设备2分别与网络设备的多个载波相连，终端设备2的服务小区由主小区和两个辅小区(辅小区1和辅小区2)组成，终端设备1的服务小区由主小区辅小区1组成。多个小区(载波)中的至少部分小区分别形成终端设备1和终端设备2的服务小区。
应理解，本发明实施例仅以图3所示的应用场景为例进行说明，但本发明实施例并不限于此，例如，该系统可以包括更多的终端设备和载波。
下面结合图4详细说明本申请提供的激活辅小区的方法，图4是本发明实施例的激活辅小区的方法100的示意性流程图，该方法100可以应用在图3所示的场景中，当然也可以应用在其他通信场景中，本发明实施例在此不作限制。
如图4所示，该方法100包括：
S110，终端设备在接收到网络设备发送的辅小区激活命令后，从第一时间单元开始，按照第一周期向该网络设备发送第一上行信号。
S120，该网络设备从该第一时间单元开始，按照第一周期接收该第一上行信号。
S130，该终端设备确定第二时间单元，该第二时间单元为最长激活时间到达的时间单元或者接收到该网络设备发送的调度命令的时间单元。
S140，该终端设备从第二时间单元之后，按照第二周期或者基于该网络设备调度的方式向该网络设备发送第二上行信号，该第二周期大于该第一周期。
S150，该网络设备从第二时间单元开始，按照第二周期基于该网络设备调度的方式接收该第二上行信号。
本发明实施例提供的激活辅小区的方法，在激活过程中，即从终端设备接收到激活命令后的第一时间单元开始到接收到调度命令或者到达最长激活时间的时间单元的这段时间内，按照较小的第一周期向网络设备发送该第一上行信号，增大了网络设备接收到用于通知该辅小区已经激活的该第一上行信号的概率，使得网络设备可以更早的接收到该第一上行信号，从而更早的根据该第一上行信号向终端设备发送调度命令，缩短了网络设备获知该辅小区已经激活成功所用的时间，减小激活延时，使得网络设备可以更早的调度该辅小区。在接收到调度命令(信令或数据)或者到达最长的激活时间后，终端设备以较大的第二周期或基于网络设备调度的方式发送第二上行信号，减少了第二上行信号消耗的网络资源。从而解决在辅小区激活过程中和激活后，网络资源消耗和激活延时不平衡的问题， 提高数据传输效率和用户体验。
具体而言，在S110中，网络设备会向终端设备发送辅小区激活命令。相应的，终端设备在接收到该辅小区激活命令后，从第一时间单元开始，按照第一周期向该网络设备发送第一上行信号。在终端设备接收到该辅小区激活命令至第一时间单元之间的这段时间内，终端设备完成该辅小区激活命令的接收，即进行解调、译码等处理。
应理解，该第一时间单元是该终端设备能够发送该第一上行信号的时间单元，即能够发送(be capable to transmit)该第一上行信号，具备发送该第一上行信号能力的时间单元。应理解，在第一时间单元，终端设备只是具备了开始发送该第一上行信号的能力，终端设备也可以在第一时间单元之后的某个时间单元开始发送该第一上行参考信号。本发明实施例在此不作限制。在终端设备完成激活命令的接收后，会向网络设备发送有效的CSI报告，该第一上行信号可以包括该有效的CSI报告。可选的，该第一时间单元可以是发送该有效的CSI报告的时间单元。该有效的CSI报告用于告知网络设备该辅小区所在的载波的信道状态。在接收到该激活命令后，该终端设备便开始进行硬件准备工作，例如，锁相环调整、晶振调整、自动增益控制、射频链激活等。终端设备完成硬件准备工作，表明该辅小区已经激活成功。
应理解，该第一时间单元可以是终端设备完成硬件准备的时间单元，该第一时间单元也可以是在终端设备完成硬件准备前的某一时间单元，该第一时间单元还可以是该终端设备能够发送该第一上行信号，并且具备发送SRS、PDCCH检测以及功率余量上报的能力的时间单元。本发明实施例在此不作限制。
还应理解，在本申请中，时间单元和时刻可以表达相同的含义，都可以用来表示时间的节点，可以相互替换。例如，该第一时间单元可以是第一时刻，该第一时间单元可以在一个子帧，或在一个时隙(slot)，或一个短时隙(mini-slot)，或一个短传输时间间隔(short transmission time interval，sTTI)上。本发明实施例在此不作限制。
还应理解，该辅小区激活命令可以在媒体接入控制信道单元(media access control channel element，MAC CE)上发送，或是在PDCCH上发送，本发明实施例在此不作限制。
还应理解，该辅小区可以是小区形式，发送主同步信号，辅同步信号，以及广播消息，或该辅小区可以是波束形式，发送波束导频信号。波束导频信号按照一定周期发送，或该辅小区可以是分配单元(distribute unit)形式，该分配单元只包括用户面，该分配单元与中央单元(central unit)连接，该中央单元提供控制面信息。
还应理解，该辅小区激活命令中的辅小区添加或修改信令可以是以辅小区小区组索引的形式发送，也可以是以单个辅小区索引方式发送。本发明实施例在此不作限制。
由于终端设备在第一时间单元时已经具备了发送该第一上行信号的能力，即能够发送(be capable to transmit)该第一上行信号，因此，从第一时间单元开始，会按照第一周期向网络设备发送第一上行信号，用于通知网络设备该辅小区已经激活成功了。相应的，在S120中，该网络设备从第一时间单元开始，也会按照第一周期接收该终端设备发送的第一上行信号。
可选的，第一时间单元可以是从接收到辅小区激活命令的时间单元开始后的第八个子帧，表示终端设备最早在该第八个子帧上，发送一个有效的CSI报告(transmit valid CSI  report)，第一时间单元的值也可以是其他值。由于不同资源参数配置不同，该参数配置可以称为“numerology”，例如，不同业务配置的循环前缀(cyclic prefix，CP)长度、传输时间间隔(transmission time interval，TTI)、子载波间隔、符号(symbol)个数、资源块(resource block，RB)位置、时隙长度和帧格式等不同。因此，该第一时间单元和接收到辅小区激活命令的时间单元之间的时长也可以是根据不同numerology对应的值，例如，针对2个符号的TTI长度，可以是16个TTI，针对1ms的TTI长度，可以是8个1ms的子帧。本发明实施例在此不作限制。
应理解，终端设备也可以在第一时间单元之后的某个时间单元，向网络设备发送该第一上行信号。例如，可以在终端设备完成硬件准备的时间单元开始，向网络设备发送该第一上行信号。第一时间单元还可以是在终端设备完成硬件准备前的某一时间单元，也可以是终端设备完成硬件准备后的某一时间单元。本发明实施例在此不作限制。
在S130，该终端设备确定第二时间单元，该第二时间单元为最长激活时间到达的时间单元或者接收到该网络设备发送的调度命令的时间单元，其中，时间上，第二时间单元在该第一时间单元之后。
具体而言，在网络设备成功接收到该第一上行信号后，便会向终端设备发送调度命令，用于调度该终端设备进行数据的接收或者发送。第二时间单元可以是终端设备接收到该调度命令的时间单元。该调度命令可以是信令或者数据。该第二时间单元也可以是网络设备正确接收到该第一上行信号的时间单元。或者，在系统的配置信息中，会配置一个最大的激活时长，该最长激活时间为协议规定或预定义的，是指终端设备接收到激活命令后，到终端设备激活辅小区所用的最长时间，例如3GPP 36.133中定义的n+24毫秒或n+34毫秒。激活辅小区的最晚的时间不能晚于(no later than)该最长激活时间。
在到达该最大激活时间的时间单元(最晚激活时间)，无论网络设备是否正确接收到该第一上行信号，网络设备都会向终端设备发送调度命令。因此，该第二时间单元可以为是最长激活时间到达的时间单元。例如，最大的激活时长的值可以为24ms或34ms，也可以是24个sTTI或34个sTTI，也可以是24个slot或34个slot等。本发明实施例在此不作限制。
S140，该终端设备在该第二时间单元之后，按照第二周期向该网络设备发送第二上行信号，该第二周期大于该第一周期，或者基于该网络设备调度的方式向该网络设备发送第二上行信号，这里不做限定。
S150，该网络设备从第二时间单元开始，按照第二周期接收该第一上行信号。
具体而言，从S140中，在该第二时间单元之后，不需要和之前激活辅小区一样频繁地向网络设备发送第二上行信号，因此，该终端设备按照第二周期或者基于该网络设备调度的方式向该网络设备发送第二上行信号，该第二周期大于该第一周期。基于网络设备调度的方式可以理解为在网络设备需要该终端设备的信息时，便会向该终端设备发调度信息，终端设备接收到该调度信息时，便会向网络设备上报第二上行信号，该基于该网络设备调度的方式是指该网络设备以PDCCH/或MAC CE的方式进行调度。该第二上行信号用于网络设备进行相干解调和检测，以及信道质量的测量等，以便于进行后续的数据传输。这样会减少网络资源的消耗。相应的，在S150中，该网络设备按照第二周期或者基于该网络设备调度的方式接收第二上行信号。
应理解，在该第二时间单元之后，该终端设备还可以停止向网络设备发送该第二上行信号，例如，在该终端设备处于静止的状态或者无数据发送的状态等。或者还可以是基于其他可以降低网络资源消耗的方式向网络设备上报第二上行信号，例如，非周期的方式等。本发明实施例在此不作限制。
还应理解，该终端设备从接收到辅小区的激活命令开始，或者从接收到辅小区的激活命令之后的某个时间开始，会周期性的接收网络设备发送的导频信号，该导频信号用于向终端设备通知该辅小区的相关信息，使终端设备可以快速的与该辅小区取得下行同步，进而更早的完成硬件准备工作，更早的向网络设备发送第一上行信号。可以理解，终端设备越早的接收到该导频信号，可以更早的完成下行同步，可以更早的完成硬件准备工作，即更早的完成该辅小区的激活。这样，终端设备可以更早的向网络设备发送第一上行信号。即在激活过程中，网络设备以较短的周期发送该导频信号，终端设备以较短的第一周期发送该第一上行信号，可以更加有效的缩短通知网络设备该辅小区已经激活所用的时间，使得网络设备更早的获知该辅小区已经激活的通知。在第二时间单元之后，网络设备以较长的周期发送导频信号，终端设备以较长的第二周期或者基于调度的方式发送第二上行信号，可以更有效的节省网络资源。
还应理解，该第一周期可以是系统规定的周期，例如，可以1ms或1个TTI，或者是其他的数值。可选的，该第一周期越短，激活时间将会越短。例如，该第一周期1个slot，或一个sTTI等。本发明实施例在此不作限制。该第二周期大于该第一周期，可选的，该第二周期越长，网络资源的消耗就会越小。
本发明实施例提供的激活辅小区的方法，在激活辅小区的过程中，终端设备按照第一周期向网络设备发送第一上行信号，增加了终端设备发送的用于向网设备通知该辅小区已经激活完成的第一上行参考信号的动作。从而使得网络设备可以更早的根据该第一上行信号发送调度命令，可以减少激活延时。在接收到调度命令后，终端设备以较大的第二周期或基于网络设备调度的方式发送第二上行信号，减少了发送第二上行信号消耗的网络资源。在减少资源消耗的情况下，可以快速通知网络设备该辅小区已经激活，减少激活延时。解决在辅小区激活中，网络资源消耗和激活时延不平衡的问题，提高数据传输效率和用户体验。
可选的，作为一个实施例，在S110之前，该方法还包括：
S109，该网络设备向该终端设备发送该辅小区的配置消息，该配置消息包括该第二周期的配置信息以及该基于网络设备调度的方式的配置信息中至少一种，以及该第一周期的配置信息。

应理解，该第一周期、第二周期、基于网络设备调度的方式以及停止发送该第二上行信号等信息可以是通过该配置消息通知给终端设备的，也可以是网络设备和终端设备预先协商好的，即系统预先配置的。本发明实施例在此不作限制。
还应理解，该配置消息还可以包括用于指示终端设备是否需要在不同的时间段内按照不同的周期发送该第一上行信号和该第二上行信号的指示信息。例如，该指示信息可以指示终端设备始终按照相同的方式或者周期发送该第一上行信号和该第二上行信号，也可以是按照该配置消息中包括的不同周期在不同的时间段发送该第一上行信号和该第二上行信号。本发明实施例在此不作限制。
还应理解，该第一周期、第二周期、基于网络设备调度的方式以及停止发送该第二上行信号等配置信息还可以是通过广播消息通知给该终端设备，以及与该终端设备同处于一个网络设备的其他终端设备。本发明实施例在此不作限制。
还应理解。该配置消息可以包括该第二周期的配置信息、基于网络设备调度的方式的配置信息以及停止发送该第二上行信号的配置信息中的任意一种。该配置消息中还可以包括上述三种配置信息的任意组合，终端设备根据其他信息或者条件去选择一种或者在不同的时间段内执行不同的方式。本发明实施例在此不作限制。
可选的，作为一个实施例。该第一上行信号包括第一信道状态信息CSI和/或第一探测参考信号SRS，该第二上行信号包括第二CSI和/或第二SRS。
具体而言，终端设备在完成硬件准备工作后，向网络设备发送的第一上行信号可以包括第一CSI和/或第一SRS，该第一CSI用于向网络设备通知该终端设备的主小区信道和辅小区信道状态，便于网络设备进行上行信道质量测量。该第一SRS为网络设备的调度提供参考，参考的内容可以是该主小区的信道质量和辅小区的信道质量。网络设备根据该第一CSI和/或第一SRS，向该终端设备发送调度该辅小区的调度命令。
该第二上行信号包括第二CSI和/或第二SRS，用于在激活该辅小区之后，向网络设备上报该主小区和辅小区的信道状态信息以及用于网络设备的相干解调和检测，以便于网络设备和终端设备有效的进行数据的传输。
应理解，该第二CSI和第一CSI可以相同。可以不同。该第二SRS可以和该第一SRS相同，可以不同。本发明实施例在此不作限制。
还应理解，该第一CSI和该第二CSI可以通过其他小区或该辅小区发送。第一SRS和该第二SRS则需要通过该辅小区发送。
还应理解，该第一上行信号和该第二上行信号还可以包括其他上行信号，例如，上行解调参考信号等。本发明实施例在此不作限制。
本发明实施例还提供了另一种激活辅小区的方法200，该方法200可以应用在图3所示的场景中，当然也可以应用在其他通信场景中。本发明实施例在此不作限制。
如图5所示，该方法200包括：
S210，网络设备在第三时间单元向终端设备发送辅小区激活命令，相应的，终端设备 在第三时间单元接收到该辅小区激活命令。
S220，该网络设备从该第三时间单元开始，按照第一周期向该终端设备发送第一导频信号。
S230，该终端设备从该第三时间单元开始，按照第一周期接收该网络设备发送的第一导频信号。
S240，该网络设备确定第四时间单元，该第四时间单元为最长激活时间达到的时间单元或者为该网络设备向该终端设备发送调度命令的时间单元。
S250，在该第四时间单元之后，该网络设备按照第二周期向该终端设备发送第二导频信号，该第二周期大于该第一周期。
S260，在该第四时间单元之后，该终端设备按照第二周期接收该网络设备发送的第二导频信号。
本发明实施例提供的激活辅小区的方法，在辅小区激活过程中，即终端设备收到激活命令和收到调度命令的这段时间内，网络设备按照较小的第一周期向终端设备发送第一导频信号，增大了终端设备接收到用于下行同步的第一导频信号的概率，可以使得终端设备更早的完成下行同步，进而更早的完成硬件准备工作，即完成辅小区的激活。从而可以更早的向网络设备发送用于通知该辅小区已经激活成功的上行信号，网络设备便可以根据该上行信号，可以更早的发送调度命令。该调度命令用于调度该终端设备进行数据的接收或者发送。可以减少网络设备获知辅小区激活成功所用的时间，减小激活时延。在发送调度命令后，网络设备以较大的第二周期发送第二导频信号，减少了发送第二导频信号消耗的网络资源。从而解决在辅小区激活过程中和激活后，网络资源消耗和激活时延不平衡的问题，提高数据传输效率和用户体验。
具体而言，在S210中，网络设备在第三时间单元向终端设备发送辅小区激活命令，用于向终端设通知开始激活该辅小区。相应的，终端设备在第三时间单元接收到该辅小区激活命令。应理解，在本申请中，时间单元和时间单元可以表达相同的含义，可以互换。例如，该第三时间单元可以是第三时间单元，该第三时间单元可以是在一个子帧，或在一个slot，或一个mini-slot，或一个sTTI上。本发明实施例在此不作限制。
还应理解，该辅小区激活命令可以在MAC CE上发送，或是在PDCCH上发送，本发明实施例在此不作限制。
还应理解，该辅小区激活命令中的辅小区添加或者修改信令可以是以辅小区小区组索引的形式发送，也可以是以单个辅小区索引的方式发送。本发明实施例在此不作限制。
在S220中，该网络设备从该第三时间单元开始，按照第一周期向该终端设备发送第一导频信号，用于该终端设备根据该第一导频信号，完成下行同步、有效的信道状态信息测量，最终完成硬件准备工作，例如，锁相环调整、晶振调整、自动增益控制、射频链激活等。在终端设备完成硬件准备工作后，会向网络设备发送上行信号，例如，可以是CSI和/或SRS，用于通知终端设备的硬件准备工作已经完成。网络设备收到该上行信号后，便会向终端设备发送调度命令，用于调度该终端设备执行数据接收或发送。相应的，在S230中，该终端设备从该第三时间单元开始，按照第一周期接收该网络设备发送的第一导频信号。
在S240中，该网络设备确定第四时间单元，该第四时间单元为最长激活时间达到的 时间单元或者为该网络设备向该终端设备发送调度命令的时间单元。
在网络设备成功接收到该上行信号后，便会向终端设备发送调度命令，用于调度该终端设备进行数据的接收或者发送。第四时间单元可以是网络设备向终端设备发送调度命令的时间单元。该第四时间单元也可以是网络设备正确接收到该上行信号的时间单元。或者，在系统的配置信息中，会配置一个最长的激活时长，该最长激活时间为协议规定或预定义的，是指终端设备接收到所述激活命令后，到终端设备激活所用的最长时间，例如3GPP36.133中定义的n+24毫秒或n+34毫秒。激活辅小区的最晚的时间不能晚于(no later than)该最长激活时间的时间单元。在到达该最大激活时间的时间单元(最晚激活时间)，无论网络设备是否正确接收到该第一上行信号，网络设备都会向终端设备发送调度命令。因此，该第四时间单元可以为最长激活时间到达的时间单元。例如，最大的激活时长的值可以为24ms或34ms，也可以是24个sTTI或34个sTTI，也可以是24个slot或34个slot等。本发明实施例在此不作限制。
S250，在该第四时间单元之后，该网络设备按照第二周期向该终端设备发送第二导频信号，该第二周期大于该第一周期。
具体而言，在该第四时间单元之后，不需要和发送调度命令之前一样频繁的向终端设备发送第二导频信号。因此，该网络设备按照第二期向该终端设备发送第二导频信号，该第二周期大于该第一周期。该第二导频信号用于后续的网络设备和终端设备之间进行相干解调和检测，以及信信道质量的测量等，以便于进行后续的数据传输。相应的，在S260中，终端设备在该第四时间单元之后，该终端设备按照第二周期接收该网络设备发送的第二导频信号。
应理解，在第四时间单元之后，该网络设备还可以按照其他可以降低网络资源消耗的方式向终端设备发送第二导频信号，例如，非周期的方式等。本发明实施例在此不作限制。
还应理解，该第一周期可以是系统规定的周期，例如，可以1ms，或者是其他的数值。可选的，该第一周期越短，激活时间将会越短。例如，该第一周期可以是1ms，或1个slot，或一个sTTI等。该第二周期大于该第一周期，可选的，该第二周期越长，网络资源的消耗就会越小。
还应理解，在该网络设备向终端设备发送该第一导频信号后，会周期性接收该终端设备发送的上行信号。可以理解。网络设备越早的接收到该上行信号，也会更早获知该辅小区已完成激活。即网络设备以较短的第一周期发送该第一导频信号，终端设备根据该第一导频信号，更早的完成下行同步和硬件准备工作，即更早的完成辅小区的激活。然后终端设备以较小的周期向网络设备发送上行信号。可以减少通知网络设备辅小区已经激活所用的时间。可以更加有效的缩短激活延时。在辅小区激活后，网络设备以较长的第二周期发送第二导频信号，终端设备以较长的周期或者基于调度的方式发送第二上行信号，可以更有效的节省网络资源。
本发明实施例提供的激活辅小区的方法，在激活过程中，网络设备按照较小的第一周期向终端设备发送第一导频信号，可以使得终端设备更早的完成辅小区的激活，从而可以更早的向网络设备发送用于通知该辅小区已经激活完成的上行信号。从而使得网络设备可以更早的根据该上行信号发送调度命令，减少激活延时。在激活完成后，网络设备以较大的第二周期发送第二导频信号，减少了发送第二导频信号消耗的网络资源。解决辅小区激 活过程中和激活后，网络资源消耗和激活时延不平衡的问题，提高数据传输效率和用户体验。
可选的，作为一个实施例，在S210之前，该方法还包括：
S209，该网络设备发送该辅小区的配置消息，该配置消息该第一周期的配置信息和该第二周期的配置信息。
具体而言，在网络设备向终端设备发送该激活命令前，该网络设备会向终端设备发送辅小区的配置消息，该辅小区的配置消息可以是RRC重配置消息。该配置消息包括该辅小区添加或修改信令。例如，终端设备会根据该辅小区添加信令，将该配置消息中的载波添加为该辅小区所在的载波，该辅小区就会处于非激活状态。该配置消息还包括该第一周期的配置信息和该第二周期的配置信息。网络设备根据协议规定、该配置消息或者其他用于指示该网络设备根据该第一周期和该第二周期发送该第一导频信号和该第二导频信号的指示信息，例如，该指示信息可以是向网络设备指示在不同时间段内按照不同的方式去发送该第一导频信号和该第二导频信号。网络设备根据这些信息，在不同的时间段内按照不同的周期去发送该第一导频信号和该第二导频信号。终端也会根据该重配置信息和该指示信息，在不同的时间段内按照不同的周期接收该第一导频信号和第二导频信号。
应理解，该第一周期和第二周期等信息可以是通过该配置消息通知给终端设备的，也可以是网络设备和终端设备预先协商好的，即系统预先配置的。本发明实施例在此不作限制。
还应理解，该配置消息还可以包括用于指示网络设备是否需要在不同的时间段内按照不同的周期发送该第一导频信号的指示信息。例如，该指示信息可以指示网络设备始终按照相同的周期发送该第一导频信号和该第二导频信号，也可以是按照该配置消息中包括的不同周期在不同的时间段发送该第一上行信号和该第二导频信号。即网络设备可以根据该指示信息，确定是否需要在激活辅小区的过程中，按照第一周期发送第一导频信号，在激活辅小区后，按照第二周期发送该第二导频信号。本发明实施例在此不作限制。
