Capacity station activation method, radio communication apparatus, and system

摘要

Embodiments of the present invention provide a capacity station activation method and system. The method includes: A coverage station sends activation control information to a capacity station, where the activation control information is used to enable the capacity station to send a pilot signal to a user in a power increasing manner; receives a measurement result of measuring the pilot signal by the user; determines, according to the measurement result, a capacity station that needs to be activated to meet a system requirement; and sends activation information to a determined capacity station that needs to be activated to activate the capacity station. With the capacity station activation method and system in the embodiments of the present invention, a capacity station that needs to be activated can be determined more accurately, and furthermore, transmit power of an activated capacity station can be controlled, thereby reducing energy consumption of a whole system.

主权项

1. A capacity station activation method, comprising:
sending first activation control information to a capacity station, wherein the first activation control information is used to enable the capacity station to send a pilot signal at first transmit power to a user who is in a linked state with a coverage station, and the capacity station belongs to the coverage station; receiving a first measurement result of measuring the pilot signal by the user, and determining, according to the first measurement result, a capacity station that needs to be activated to meet a system requirement; sending activation information to the capacity station that needs to be activated, so that the capacity station that needs to be activated works at the first transmit power after being activated; and if a capacity station that needs to be activated to meet a system requirement cannot be selected according to the first measurement result, sending second activation control information to the capacity station, wherein the second control information is used to enable the capacity station to send a pilot signal at second transmit power to the user who is in a linked state with the coverage station; receiving a second measurement result of measuring the pilot signal by the user, and determining, according to second measurement result, a capacity station that needs to be activated; and sending activation information to the capacity station that needs to be activated, so that the capacity station that needs to be activated works at the second transmit power after being activated; wherein, the first transmit power is smaller than the second transmit power.
