Abstract
A method for adjusting transmit power of a serving base station in a wireless communication system is provided. The method includes receiving measurement information indicating channel states of the serving base station and at least one neighbor base station from at least one serving user equipment (UE), receiving first information including information about transmit power of the at least one neighbor base station from the at least one neighbor base station, and determining the transmit power of the serving base station using the measurement information and the first information.
Claims17
A serving base station configured to transmit power of the serving base station in a wireless communication system, the serving base station comprising:
- a transceiver;
- and
- a processor configured to control the transceiver, wherein the processor is configured to:
- obtain measurement information indicating channel states of the serving base station and at least one neighbor base station from at least one serving user equipment (UE) via the transceiver,
- obtain first information including information about transmit power of the at least one neighbor base station from the at least one neighbor base station,
- identify information related to a signal-to-interference-plus-noise ratio (SINR) of the at least one serving UE using the measurement information and the first information, and
- identify the transmit power of the serving base station using the measurement information, the first information, and the information related to the SINR of the at least one serving UE,
- wherein the information related to the SINR of the at least one serving UE comprises one of information about respective SINRs of the at least one serving UE, information about a sum of the respective SINRs of the at least one serving UE, or information about a mean of the respective SINRs of the at least one serving UE.
A serving base station configured to adjust transmit power of the serving base station in a wireless communication system, the serving base station comprising:
- a transceiver;
- and
- a processor configured to control the transceiver, wherein the processor is configured to:
- obtain measurement information indicating channel states of the serving base station and at least one neighbor base station from at least one serving user equipment (UE) via the transceiver,
- obtain first information including information about transmit power of the at least one neighbor base station from the at least one neighbor base station,
- identify the transmit power of the serving base station using the measurement information and the first information,
- receive third information regarding a request for adjusting an upper limit of the transmit power of the serving base station from the at least one neighbor base station, and
- adjust the upper limit of the transmit power of the serving base station using the third information.
A serving base station configured to adjust transmit power of the serving base station in a wireless communication system, the serving base station comprising:
- a transceiver;
- and
- a processor configured to control the transceiver, wherein the processor is configured to:
- receive measurement information indicating channel states of the serving base station and at least one neighbor base station from at least one user equipment (UE) served via the transceiver,
- receive, from the at least one neighbor base station, first information including information about transmit power of the at least one neighbor base station and information about estimated signal-to-interference-plus-noise ratios (SINRs) related to at least one UE served by the at least one neighbor base station for a plurality of variations in the transmit power of the serving base station,
- determine a received SINR of the at least one UE served by the serving base station using the measurement information,
- determine the transmit power of the serving base station using the received SINR of the at least one UE served by the serving base station and the information about the estimated SINRs related to the at least one UE served by the at least one neighbor base station,
- estimate, based on the information about the transmit power of the at least one neighbor base station and the measurement information, SINRs related to the at least one UE served by the serving base station for a plurality of variations in the transmit power of the at least one neighbor base station, and
- transmit second information including the estimated SINRs related the at least one UE served by the serving base station and information about the transmit power of the serving base station to one or more of the at least one neighbor base station.
