Uplink power control

摘要

A power control applied to a radio network controller (40) when a user equipment (300) is in communication with a serving radio base station (10) and at least one other radio base station (20) involves the radio network controller (40) providing a quality representation of an uplink control channel (12) from the user equipment (300) to the serving radio base station (10). The radio network controller (40) generates an updated power quality target for a reference control channel based on the quality representation and transmits the updated power quality target to at least one of the serving radio base station (10) and the at least one other radio base station (20). Alternatively, the radio network controller (40) generates an updated power offset for the uplink control channel (12) relative a reference control channel based on the quality representation and transmits the updated power offset to the user equipment (300).

主权项

1. A power control method in a communication network when a user equipment is in communication with a serving radio base station and at least one other radio base station over a radio interface on uplink channels, and the serving radio base station is connected to a radio network controller configured to implement the power control method, the method comprising:
providing a quality representation of an uplink control channel from the user equipment to the serving radio base station; generating an updated power quality target for a reference control channel based on the quality representation; and transmitting the updated power quality target to at least one of the serving radio base station and the at least one other radio base station to control at least one of the serving radio base station and the at least one other radio base station to transmit at least one transmit power control command to the user equipment to trigger an adjustment of a transmit power of the uplink control channel.
