Processing method for tracking ue in low power mode, and device

A processing method for tracking a user equipment (UE) in a low power mode, the method comprising:

• sending, by a network device, transmission configuration information to the UE for sending an uplink tracking signal according to a discontinuous transmission mode, wherein the transmission configuration information comprises a transmission cycle for sending the uplink tracking signal by the UE;
• receiving, by the network device, the uplink tracking signal that is sent by the UE based on the transmission configuration information;
• determining, by the network device, timing advance (TA) adjustment information of the UE based on the uplink tracking signal;
• and
• sending, by the network device, the TA adjustment information to the UE.

User equipment, comprising:

• a receiver, configured to obtain transmission configuration information between the user equipment and a network device, wherein the transmission configuration information indicates that an uplink tracking signal is to be sent according to a discontinuous transmission mode, and the transmission configuration information comprises a transmission cycle;
• a transmitter, configured to:
• when the user equipment enters a low power mode, send an uplink tracking signal to the network device based on the transmission configuration information;
• and
• wherein the receiver is further configured to receive timing advance (TA) adjustment information sent by the network device in response to the uplink tracking signal.

A network device, comprising:

• a transmitter, configured to send transmission configuration information to user equipment (UE) for sending an uplink tracking signal according to a discontinuous transmission mode, wherein the transmission configuration information comprises a transmission cycle for sending the uplink tracking signal by the UE;
• a receiver, configured to receive the uplink tracking signal that is sent by the UE based on the transmission configuration information;
• a processor, configured to determine timing advance (TA) adjustment information of the UE based on the uplink tracking signal;
• and
• wherein the transmitter is further configured to send the TA adjustment information to the UE.
