Abstract
A user equipment (UE) may adjust its uplink transmission power and timing for communications with a target cell while awaiting completion of a baton handover procedure. The amount of adjustments for the uplink transmission power/timing may be based on an amount of time remaining before baton handover failure is declared. The steps size of the adjustments may increase as the time remaining before handover failure becomes smaller.
Claims20
A method of wireless communication, comprising:
- tuning uplink communications to a target cell as part of a baton handover;
- and
- adjusting uplink transmission power or timing by a user equipment, prior to receipt of a transmit power control command, while waiting for the baton handover to complete.
An apparatus for wireless communication, comprising:
- means for tuning uplink communications to a target cell as part of a baton handover;
- and
- means for adjusting uplink transmission power or timing by a user equipment, prior to receipt of a transmit power control command, while waiting for the baton handover to complete.
A computer program product for wireless communication in a wireless network, comprising:
- a non-transitory computer-readable medium having program code recorded thereon, the program code comprising:
- program code to tune uplink communications to a target cell as part of a baton handover;
- and
- program code to adjust uplink transmission power or timing by a user equipment, prior to receipt of a transmit power control command, while waiting for the baton handover to complete.
An apparatus for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured:
- to tune uplink communications to a target cell as part of a baton handover;
- and
- to adjust uplink transmission power or timing by a user equipment, prior to receipt of a transmit power control command, while waiting for the baton handover to complete.
