Abstract
A technique relating to resource configuration in a wireless communication network. A terminal device in the wireless communication network receives information about supplemental resource from a source cell. Then the terminal device determines a time interval, in which the supplemental resource is available to the terminal device, in a transition period of a handover from the source cell to a target cell based on a timer associated with a random access procedure in the handover. In this way, the terminal device may use the supplemental resource during the handover.

A method implemented at a terminal device for use in a wireless communication network, comprising:
- receiving information about supplemental resource from a source cell of the wireless communication network;
- and
- determining a time interval in a portion of a transition period of a handover of the terminal device from the source cell to a target cell, in which the supplemental resource is available to the terminal device during the time interval, wherein a first timer and the time interval commence at a receiving of a connection reconfiguration message from the source cell, wherein when the first timer expires without the terminal device completing target cell selection, utilizing a second timer to extend the time interval for target cell selection, and wherein the time interval ends upon successful target cell selection or upon expiry of the second timer.
An apparatus implemented at a terminal device for use in a wireless communication network, comprising:
- a receiver configured to receive information about supplemental resource from a source cell of the wireless communication network;
- and
- a controller configured to determine a time interval in a portion of a transition period of a handover of the terminal device from the source cell to a target cell, in which the supplemental resource is available to the terminal device during the time interval, wherein a first timer and the time interval commence at a receiving of a connection reconfiguration message from the source cell, wherein when the first timer expires without the terminal device completing target cell selection, utilize a second timer to extend the time interval for target cell selection, and wherein the time interval ends upon successful target cell selection or upon expiry of the second timer.
A method implemented at a network device in a wireless communication network, comprising:
- preparing for transmission to a terminal device, information about supplemental resource for use by the terminal device during a handover of the terminal device from a source cell to a target cell, the information including a time interval in a portion of a transition period of the handover, in which the supplemental resource is available to the terminal device during the time interval, wherein a first timer and the time interval commence at a receiving of a connection reconfiguration message from the source cell by the terminal device, wherein when the first timer expires without the terminal device completing target cell selection, utilizing a second timer to extend the time interval for target cell selection at the terminal device, and wherein the time interval ends upon successful target cell selection by the terminal device or upon expiry of the second timer;
- and
- sending the information to the terminal device by the source cell.
An apparatus implemented at a network device in a wireless communication network, comprising:
- a controller configured to cause a transmission of information to a terminal device, the information about supplemental resource for use by the terminal device during a handover of the terminal device from a source cell to a target cell, the information including a time interval in a portion of a transition period of the handover, in which the supplemental resource is available to the terminal device during the time interval, wherein a first timer and the time interval commence at a receiving of a connection reconfiguration message from the source cell by the terminal device, wherein when the first timer expires without the terminal device completing target cell selection, utilizing a second timer to extend the time interval for target cell selection at the terminal device, and wherein the time interval ends upon successful target cell selection by the terminal device or upon expiry of the second timer.
