The present invention relates to a method in which an upper layer entity allocates resources to a plurality of access points (APs) in a wireless access system, including the plurality of APs and the upper layer entity for managing the plurality of APs, the method comprising the step of: sensing a change in minimum guaranteed resource amount allocated to each of the APs; acquiring, from each of the APs, AP-level topology information according to a degree of interference with adjacent APs and AP weight information given to each AP by a service provider; determining a minimum guaranteed resource amount for each of the APs based on the acquired AP-level topology information and AP weight information; and transmitting the determined minimum guaranteed resource amount to each of the APs.

Method and apparatus for allocating minimum guaranteed resource amount to access point in wireless access system

The present invention relates to a method in which a first station receives position information using a second station positioned in the vicinity of the first station. The method includes the steps of: receiving a station identifier (STID) and at least one fake identifier (ID) from a base station; obtaining a fake ID of the second station; requesting position information on the second station from the base station using the fake ID of the obtained second station; and receiving the position information on the second station of the base station, wherein the fake ID is an identifier used for position measurement and is mapped to the STID.

Method and apparatus for measuring a position in a wireless access system

A method for cancelling ghost effects in an image signal processor which is capable of enhancing a convergence rate of a coefficient of a filter and a performance of cancelling ghost effects in a system, by alternately performing the updatings of the coefficients of an FIR filter and an IIR filter in a system using both the FIR filter and the IIR filter, includes initializing an FIR filter bank and an IIR filter bank, updating the FIR filter bank by performing an algorithm for updating a coefficient of a filter with a data having a ghost effect and a data in which a reference GCR data is filtered by the IIR filter, updating the IIR filter bank by performing the algorithm for updating a coefficient of a filther with the reference GCR data and a data in which an X(z) is filtered by the FIR filter bank, and obtaining an FIR filter bank and an IIR filter bank in each of which an error is minimized.
