Abstract
A method for time synchronization determination and related products are provided. The method includes the following. A terminal device receives a handover command from a first device, where the first device is a device currently accessed by the terminal device, and the handover command indicates that the terminal device hands over from the first device to a second device. The terminal device obtains and determines time synchronization information of the second device.
Claims18
A method for time synchronization determination, comprising:
- receiving, by a terminal device, a handover command from a first device, the first device being a device currently accessed by the terminal device, and the handover command indicating that the terminal device hands over from the first device to a second device;
- obtaining and determining, by the terminal device, time synchronization information of the second device, wherein the time synchronization information comprises one or more of:
- an indication of whether the terminal device performs propagation delay compensation, and an indication of whether the second device has performed propagation delay compensation;
- and
- determining, by the terminal device, whether to perform propagation delay compensation according to the indication of whether the terminal device performs propagation delay compensation, and/or
- determining, by the terminal device, whether the second device has performed propagation delay compensation and/or whether the terminal device needs to perform propagation delay compensation according to the indication of whether the second device has performed propagation delay compensation.

A method for time synchronization determination, comprising:
- transmitting, by a first device, a handover command to a terminal device, wherein the handover command indicates that the terminal device hands over from the first device currently accessed to a second device, and the handover command is used to be received by the terminal device to obtain and determine time synchronization information of the second device, the time synchronization information comprises one or more of:
- an indication of whether the terminal device performs propagation delay compensation, and an indication of whether the second device has performed propagation delay compensation, wherein the indication of whether the terminal device performs propagation delay compensation is used for the terminal device to determine whether to perform propagation delay compensation, and the indication of whether the second device has performed propagation delay compensation is used for the terminal device to determine whether the second device has performed propagation delay compensation and/or whether the terminal device needs to perform propagation delay compensation.
A method for time synchronization determination, comprising:
- receiving, by a second device, a handover request message transmitted from a first device;
- and
- transmitting, by the second device, an acknowledgment (ACK) message for the handover request message to the first device, wherein the ACK message is used for the first device to transmit a handover command to a terminal device according to the ACK message, the first device is a device currently accessed by the terminal device, the handover command indicates that the terminal device hands over from the first device to the second device, the handover command is used to be received by the terminal device to obtain and determine time synchronization information of the second device, the time synchronization information comprises one or more of:
- an indication of whether the terminal device performs propagation delay compensation, and an indication of whether the second device has performed propagation delay compensation, wherein the indication of whether the terminal device performs propagation delay compensation is used for the terminal device to determine whether to perform propagation delay compensation, and the indication of whether the second device has performed propagation delay compensation is used for the terminal device to determine whether the second device has performed propagation delay compensation and/or whether the terminal device needs to perform propagation delay compensation.
