Claim of US Patent No. 10,194,412

1. An access device, comprising:a receiver, a transmitter, and a memory for storing instructions; and
a processor coupled to the memory, wherein the instructions when executed by the processor cause the access device to:
receive, by the receiver a reference signal that is sent by a benefited terminal by using an access identifier of the benefited terminal, and receive a reference signal that is sent by a supporting terminal by using the access identifier of the benefited terminal,
calculate a synchronization information adjustment value of the benefited terminal according to the reference signal sent by the benefited terminal,
calculate a synchronization information adjustment value of the supporting terminal according to the reference signal sent by the supporting terminal,
send, by the transmitter, the synchronization information adjustment value of the benefited terminal to the benefited terminal,
send, by the transmitter, the synchronization information adjustment value of the supporting terminal to the supporting terminal,
receive, by the receiver, an uplink port number from the benefited terminal, wherein the uplink port number from the benefited terminal comprises an uplink port number of the benefited terminal and an uplink port number of the supporting terminal, and
determine a correspondence between an uplink port number and a benefited terminal or a supporting terminal according to a mapping rule.
