    Abstract: Methods and apparatuses are provided for controlling a wireless power transmitter. First power for charging a first wireless power receiver is transmitted. Demand power information of a second wireless power receiver is received. The demand power information includes a maximum power for the second wireless power receiver. A controller identifies whether the wireless power transmitter is capable of providing the maximum power. A power adjustment command is transmitted to the second wireless power receiver, if the wireless power transmitter is not capable of providing the maximum power. The power adjustment command requests to reduce a magnitude of power to be received by the second wireless power receiver to a level within a range that the wireless power transmitter is capable of supporting. Second power for charging the first wireless power receiver and the second wireless power receiver is transmitted based on at least the reduced magnitude of power.

    Abstract: A method and apparatus are provided for controlling power transmission in a power transmitter. The method includes receiving power information that includes a minimum voltage and a maximum voltage receivable at a power receiver; determining a reference voltage for dividing a range between the minimum voltage and the maximum voltage into a predetermined portions; dividing the range between the minimum voltage and the maximum voltage into a first voltage range between the minimum voltage and the reference voltage and a second voltage range between the reference voltage and the maximum voltage; receiving from the power receiver a report about a power reception condition including a measured voltage at the power receiver during the power transmission from the power transmitter; and adjusting and supplying the power according to which voltage range the measured voltage belongs to among the divided voltage ranges.

    Abstract: A method for acquiring a service category table required for finding a service includes acquiring information on a latest service category table by identifying version information of a service category table from a broadcasting signal received from adjacent devices during a process of searching for a device supporting a service desired among devices, and acquiring a service category table of a latest version by establishing a session connection with a device supporting the service category table of the latest version based on the information. By acquiring the information on the latest service category table, a session connection with only the device providing the desired service is established so that an optimized session connection establishing process can be performed and a total network capacity can be efficiently managed. Also, the latest service category table can be acquired from the session-connected device, and thus a new service can be easily identified.
