- the cell can belong to a macro base station or a base station corresponding to a small cell.
- the small cell here can include: Metro cell, Micro cell, Pico Cells, Femto cells, etc. These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-rate data transmission services.
- the SCell is configured through RRC dedicated signaling, and the initial configuration state is the deactivated state, and data transmission and reception cannot be performed in this state. Then the SCell is activated through the MAC CE to transmit and receive data. From the perspective of SCell configuration and activation delay, this architecture is not an optimal architecture. This time delay reduces the efficiency of CA usage and radio resources, especially in small cell deployment scenarios. In a dense small cell deployment scenario, the signaling load of each SCell is also very large, especially when each SCell needs to be configured separately. Therefore, the current CA architecture introduces additional delay, which limits the use of CA and reduces the gain of CA load sharing.
- the state of the SCell is divided into an active state and an inactive state.
- a new cell state is defined, that is, a dormant state.

- the SCell and the primary cell may not be at the same site.
- the SCell and the PCell are not at the same site. That is, for the UE, the receiving radio frequency of the base station side is not in the same geographic location for the two cells (SCell and PCell), so the TA is also different for the UE.
- LTE R11 introduces the concept of multiple TAs, that is, multiple cells can share the same TA to form a TAG group, and the UE needs to initiate a random access process in one of the cells to obtain the TA of the TAG group.
- Step 1 The gNB sends RRC signaling to the UE to add a secondary cell (SCell addition), such as configuring SCell A in the TAG group;
- SCell addition such as configuring SCell A in the TAG group;
- Step 2 The gNB activates the downlink (DL) of SCell A through MAC CE signaling;
- Step 3 The gNB sends a PDCCH order to the UE so that the UE triggers the random access procedure;
- Step 4 The gNB sends a random access response to the UE to activate the uplink (UL) of SCell A. At this time, SCell A can send and receive data.
- the cell activation delay in STAG is too long, which reduces cell throughput and UE throughput, and affects UE performance and network performance.
- this application proposes a solution for quickly activating the SCell, which can quickly activate the uplink and downlink of the secondary cell.

本申请实施例结合终端设备和网络设备描述了各个实施例,其中:终端设备也可以称为用户设备(User Equipment,UE)、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、用户代理或用户装置等。终端设备可以是WLAN中的站点(STAION,ST),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)设备、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、可穿戴设备以及下一代通信系统,例如,NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)网络中的终端设备等。
作为示例而非限定,在本申请实施例中,该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。
网络设备可以是用于与移动设备通信的设备,网络设备可以是WLAN中的接入点(Access Point,AP),GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA中的基站(NodeB,NB),还可以是LTE中的演进型基站(Evolutional Node B,eNB或eNodeB),或者中继站或接入点,或者车载设备、可穿戴设备以及NR网络中的第五代移动通信(The 5th Generation,5G)基站或者NR基站(gNB)或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中,网络设备为小区提供服务,终端设备通过该小区使用的传输资源(例如,频域资源,或者说,频谱资源)与网络设备进行通信,该小区可以是网络设备(例如基站)对应的小区,小区可以属于宏基站,也可以属于小小区(Small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。
SCell通过RRC专用信令进行配置,初始配置的状态为去激活状态,该状态下不能进行数据收发。然后通过MAC CE进行SCell的激活才能进行数据收发。从SCell配置和激活的时延的角度看,这个架构不是一个最优的架构。而这个时延又降低了CA使用和无线资源的效率,特别是小小区部署场景。在密集小小区部署场景,每个SCell的信令负荷也很大,特别是每个SCell需要单独配置情况下。因此当前CA架构引入了额外的延迟,限制了CA的使用,降低了CA负荷分担的增益。
SCell的状态分为激活状态和非激活状态,为了快速小区恢复,定义了一个新的小区状态,即休眠状态(dormant state)。在休眠状态下,终端设备测量和上报信道质量指示(Channel Quantity Indicator,CQI)和/或无线资源管理(Radio Resource Management,RRM)测量,但是不解码物理下行控制信道(Physical Downlink Control Channel,PDCCH)。同时新定义一个MAC CE控制休眠状态转换,即激活态和休眠状态之间的转换,而且在RRC信令中可以配置SCell的状态为激活状态或者休眠状态,默认为去激活状态。
为了支持射频拉远的场景,SCell和主小区(Primary Cell,PCell)可能不在同一个站址,例如,如图2所示,SCell和PCell不在同一个站址。即对于UE来说,基站侧的 接收射频对于两个小区(SCell和PCell)来说不在同一个地理位置上,所以对于UE来说,TA也是不同的。为此LTE R11中引入了多TA的概念,即多个小区可以共用同一个TA的小区组成一个TAG组,UE需要在其中的小区发起随机接入过程获取该TAG组的TA。
对于一个TAG组的小区,从配置到激活可以传输上下行数据的过程现有技术中如图3所示,具体地,可以包括如下步骤:
步骤1,gNB向UE发送RRC信令,以添加辅小区(SCell addition),如在TAG组中配置SCell A;
步骤2,gNB通过MAC CE信令激活SCell A的下行链路(downlink,DL);
步骤3,gNB向UE发送PDCCH命令,以使UE触发随机接入过程;
步骤4,gNB向UE发送随机接入响应,以激活SCell A的上行链路(uplink,UL),此时,SCell A才能进行数据收发。
