Usually, the terminal device obtains TA information through a random access process. For example, in a cell switching scenario, when the terminal device receives a switching command sent by the base station, it switches to the target cell. The terminal device initiates a random access process in the target cell and obtains TA information through the random access process to achieve uplink synchronization with the base station. Obviously, the acquisition of TA information after receiving the switching command will increase the latency overhead of subsequent access to the target cell.

For example, the chip system may include a chip and may also include other discrete devices.
3、TA3. TA
在终端设备进行上行传输时,来自同一小区的不同用户设备(User Equipment,UE)的上行传输之间互不干扰。为了保证上行传输的正交性,避免小区内(intra-cell)干扰,基站要求来自同一子帧但不同频域资源的不同UE的信号到达基站的时间基本上是对齐的。基站只要在循环前缀(Cyclic Prefix,CP)范围内接收到UE所发送的上行数据,就能够正确地解码上行数据,因此,上行同步要求来自同一子帧的不同UE的信号到达基站的时间都落在CP之内。为了保证接收侧(基站侧)的时间同步,提出了定时提前(Timing Advance,TA)的机制。对于UE
侧,TA本质上是接收到下行子帧的起始时间与传输上行子帧的时间之间的一个负偏移(negative offset)。基站通过适当地控制每个UE的偏移,可以控制来自不同UE的上行信号到达基站的时间。对于离基站较远的UE,由于有较大的传输延迟,就要比离基站较近的UE提前发送上行数据。When the terminal device performs uplink transmission, the uplink transmissions from different user equipment (UE) in the same cell do not interfere with each other. In order to ensure the orthogonality of uplink transmission and avoid intra-cell interference, the base station requires that the time when the signals from different UEs in the same subframe but different frequency domain resources arrive at the base station is basically aligned. As long as the base station receives the uplink data sent by the UE within the cyclic prefix (CP) range, it can correctly decode the uplink data. Therefore, uplink synchronization requires that the time when the signals from different UEs in the same subframe arrive at the base station falls within the CP. In order to ensure time synchronization on the receiving side (base station side), a timing advance (TA) mechanism is proposed. For UE On the UE side, TA is essentially a negative offset between the start time of receiving the downlink subframe and the time of transmitting the uplink subframe. The base station can control the time when the uplink signal from different UEs arrives at the base station by properly controlling the offset of each UE. For UEs farther away from the base station, due to the larger transmission delay, uplink data must be sent earlier than UEs closer to the base station.

Specifically, after the terminal device sends a preamble code to the network device on the resources configured in the pre-configuration information of the candidate cell, the network device determines the TA and then sends the TA information to the terminal device via a random access response message.

If m is equal to r, it means that the first network device sends all the received pre-configuration information corresponding to the r candidate cells to the terminal device. If m is less than r, it means that the first network device sends the pre-configuration information of some candidate cells among the received pre-configuration information corresponding to the r candidate cells to the terminal device.
