Abstract: This application provides a downlink transmitting system and a switching method. The downlink transmitting system includes at least one digital intermediate frequency module group, at least one Tx port group, a plurality of PAs, at least one switching switch, and an antenna array. The plurality of PAs are connected to the antenna array. The plurality of PAs are connected to all Tx ports included in the downlink transmitting system in a one-to-one correspondence. The at least one digital intermediate frequency module group is in a one-to-one correspondence with the at least one Tx port group. Each Tx port group is connected to each digital intermediate frequency module in a corresponding digital intermediate frequency module group through one switching switch. Each Tx port group includes a plurality of Tx ports.

Abstract: The technology of this application relates to a terminal device configured to receive a first message from a first access network device, where the first message is used by the terminal device to obtain a timing advance (TA) of the terminal device in a target cell, and the target cell is not a cell currently accessed by the terminal device. The terminal device is configured to send a second message to the first access network device, where the second message indicates that the terminal device has completed configuration of the target cell. In embodiments of this application, the terminal device is configured to receive the first message from the first access network device.
