Abstract

本申请实施例提供一种小区激活或去激活的方法和装置，所述方法包括：终端设备接收网络设备发送的小区改变命令；所述终端设备根据与小区激活或去激活相关的条件，激活或去激活所述小区改变命令指示的或关联的小区。根据本申请实施例，终端设备在收到小区改变命令时，或者收到(增强的)辅小区激活或去激活MAC CE时，或者根据RRC信令配置的小区激活或去激活状态，或者根据RRC信令配置的小区所在的小区组的激活或去激活状态，或者根据去激活定时器，来对小区改变命令中指示或关联的小区进行激活或去激活，能够确定小区的激活/去激活状态。

Description

小区激活或去激活的方法和装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
在辅小区(SCell)的激活/去激活中，如果MAC(Media Access Control，媒体接入控制)实体配置了一个或多个辅小区，网络可以激活和去激活该配置的辅小区。一个辅小区被配置后，这个辅小区是去激活的，除非高层将该辅小区的参数sCellState设置为activated。
目前，配置的辅小区可以在下述情况下被激活或去激活：
收到SCell Activation/Deactivation MAC CE(辅小区激活/去激活MAC CE)；
收到Enhanced SCell Activation/Deactivation MAC CE(增强的辅小区激活/去激活MAC CE)；
每个配置的辅小区被配置sCellDeactivationTimer定时器(除了配置了PUCCH的辅小区，如果有)：该定时器超时后，其关联的辅小区被去激活；
每个配置的辅小区被配置sCellState：如果该sCellState被配置，则配置辅小区后，其关联的辅小区被激活；
收到scg-State：SCG(Secondary Cell Group，辅小区组)的辅小区被去激活。
此外，对于每个配置的辅小区，如果辅小区被激活，MAC实体将会执行以下处理中的至少之一：
不在该辅小区上发送SRS(Sounding Reference Signal，探测(侦听)参考信号)；
不上报该辅小区的CSI(Channel State Information，信道状态信息)；
不在该辅小区上的UL-SCH(Uplink Shared Channel，上行链路共享信道)上发送；
不在该辅小区上的RACH(Random Access Channel，随机接入信道)上发送；
不监听该辅小区上的PDCCH(Physical Downlink Control Channel，物理下行链路控制通道)；
不监听该辅小区的PDCCH；
不在该辅小区上发送PUCCH(Physical Uplink Control Channel，物理上行链路控制通道)；
当辅小区被去激活时，中断(abort)该辅小区上正在进行的随机接入过程(如果有)。
另一方面，对于通过L1/L2(Layer 1/Layer 2，层1/层2)信令的服务小区改变，当终端从一个小区的覆盖区域移动到另一个小区的覆盖区域，在某一点需要执行服务小区改变。当前，服务小区改变由L3(Layer 3，层3)测量触发并由RRC(Radio Resource Control，无线资源控制)信令完成，为PCell(Primary Cell，主小区)和PSCell(Primary Secondary Cell，主辅小区)改变触发的同步重配置(Reconfiguration with Synchronisation)，以及SCells(Secondary Cell，辅小区)的释放增加。所有情况都涉及完整的L1(和L2)重置，导致比波束切换移动性更长的时延、更大的开销和更长的中断时间。L1/L2移动性增强的目标是确保通过L1/L2信令的服务小区改变，以减小时延、开销和中断时间。
为了减小移动性时延，基于L1/L2的小区间移动性的机制和过程包括以下内容：
多个候选小区的配置和维护，以允许候选小区的配置的快速应用；
对于可能适用的场景，基于L1/L2信令的候选服务小区(包括特殊小区和辅小区)之间的动态切换机制；
小区间波束管理的L1增强，包括L1测量和上报，以及波束指示；
定时提前管理；以及
CU-DU(Centralized Unit-Distributed Unit，中央单元-分布式单元)接口信令以支持L1/L2移动性。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，假设对于L1/L2触发的移动性，触发信息包括在MAC CE(MAC Control Element，MAC控制元素)里传递，该MAC CE至少包括一个候选配置的索引。其中，候选配置可以包括候选特殊小区和/或候选辅小区的配置，以支持载波聚合。在这种情况下，L1/L2触发的移动性需要确定辅小区的激活/去激活状态。另外，在DC(Dual Connectivity，双连接)场景下，如果支持对去激活的SCG应用L1/L2触发的移动性，还需要确定特殊小区，即主辅小区的激活/去激活状态。
针对上述问题至少之一或其他类似问题，本申请实施例提供一种小区激活或去激活的方法和装置，通过接收小区改变命令，或者接收(增强的)辅小区激活/去激活MAC  CE，或者根据RRC信令配置的小区激活或去激活状态，或者根据RRC信令配置的小区所在的小区组的激活或去激活状态，或者根据去激活定时器的状态，来对小区改变命令中指示或关联的小区进行激活或去激活，能够确定小区的激活/去激活状态。
根据本申请实施例的一方面，提供一种小区激活或去激活的装置，配置于终端设备，所述装置包括：
接收单元，其接收网络设备发送的小区改变命令；
处理单元，其根据与小区激活或去激活相关的条件，激活或去激活所述小区改变命令指示的或关联的小区。
根据本申请实施例的另一方面，提供一种小区激活或去激活的装置，配置于网络设备，所述装置包括：
发送单元，向终端设备发送小区改变命令，所述小区改变命令用于所述终端设备根据与小区激活或去激活相关的条件，激活或去激活所述小区改变命令指示的或关联的小区。
本申请实施例的有益效果之一在于：根据本申请实施例，终端设备在收到小区改变命令时，或者收到(增强的)辅小区激活或去激活MAC CE时，或者根据RRC信令配置的小区激活或去激活状态，或者根据RRC信令配置的小区所在的小区组的激活或去激活状态，或者根据去激活定时器，来对小区改变命令中指示或关联的小区进行激活或去激活，能够确定小区的激活/去激活状态。由此，允许小区改变后尽快使用辅小区进行数据传输，从而保证大数据通信。

第一方面的实施例
本申请实施例提供一种小区激活或去激活的方法，从终端设备的一侧进行说明。

801：终端设备接收网络设备发送的小区改变命令；
802：所述终端设备根据与小区激活或去激活相关的条件，激活或去激活所述小区改变命令指示的或关联的小区。
值得注意的是，以上附图8仅示意性地对本申请实施例进行了说明，但本申请不限于此。例如可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图8的记载。
根据本申请实施例，终端设备根据与小区激活或去激活相关的条件来激活或去激活小区改变命令指示的或关联的小区，由此，能够确定小区的激活/去激活状态。
在上述实施例中，小区改变命令可以是小区切换命令(cell switch command)或者小区变化命令(cell change command)或者小区移动性命令(cell mobility command)。例 如，该小区改变命令可以是来自网络设备的携带候选配置的索引的L2命令，例如cell switch MAC CE。本申请不限于此，小区改变命令还可以是其他。
在一些实施例中，小区改变命令包括候选配置的索引，并且，该小区改变命令指示该候选配置的索引对应的小区的激活或去激活状态。
例如，如果该候选配置的索引对应的小区的激活或去激活状态为0，则指示该候选配置的索引对应的小区的状态为激活；如果该候选配置的索引对应的小区的激活或去激活状态为1，则指示该候选配置的索引对应的小区的状态为去激活。
再例如，如果该候选配置的索引对应的小区的激活或去激活状态为0，则指示该候选配置的索引对应的小区的状态为去激活；如果该候选配置的索引对应的小区的激活或去激活状态为1，则指示该候选配置的索引对应的小区的状态为激活。
在一些实施例中，可以根据小区改变命令是否包括上述小区对应的小区信息，来决定小区的状态。
例如，当小区改变命令包括上述小区对应的小区信息时，指示该小区的状态为激活；和/或，当小区改变命令不包括上述小区对应的小区信息时，指示该小区的状态为去激活。
再例如，当小区改变命令包括上述小区对应的小区信息时，指示该小区的状态为去激活；和/或，当小区改变命令不包括上述小区对应的小区信息时，指示该小区的状态为激活。
在一些实施例中，小区改变命令指示的小区可以是该小区改变命令包含的小区信息所对应的小区。该小区信息可以包含在小区改变命令中，该小区信息可以是小区ID，例如PCI、NCGI，也可以是小区索引，例如在候选配置里的小区索引或PCI index，等等。
