Abstract: A communications device transmits/receives data from a mobile communications network including one or more network elements forming plural cells. Each cell is allocated a cell identifier. For each cell the network elements provide a wireless access interface providing plural communications resource elements across a frequency range of a first carrier, and divided in time into plural frames. The one or more network elements transmit in one or more of the frames a synchronization sequence, each synchronization sequence providing an indication of a cell identifier. A controller calculates an estimate of a cell identifier from the detected synchronization sequence, and uses the cell identifier to transmit/receive the data to/from the mobile communications network via the wireless access interface. A relative temporal location of the synchronization sequence within the frame provides the communications device with an indication of the cell identifier of the cell.

Abstract translation: 通信设备从包括形成多个小区的一个或多个网络元件的移动通信网络发送/接收数据。 每个单元被分配一个单元标识符。 对于每个小区，网络单元提供无线接入接口，该无线接入接口在第一载波的频率范围内提供多个通信资源单元，并将其分成多个帧。 一个或多个网络元件在一个或多个帧中发送同步序列，每个同步序列提供小区标识符的指示。 控制器根据检测到的同步序列计算小区标识符的估计，并且使用小区标识符经由无线接入接口向/从移动通信网络发送/接收数据。 帧内的同步序列的相对时间位置向通信设备提供小区的小区标识符的指示。
