摘要： An antenna weight estimation method in a mobile communication system is capable of improving the accuracy of antenna weight estimation values, thereby improving communication quality and increasing radio channel capacity. It operates instantaneous estimation and accumulative estimation in parallel, in which the former is made for estimating the antenna weight used for received SNIR estimation for transmission power control, and the latter is made for demodulating the received data. Thus, it can obtain the antenna weight for the received SNIR measurement with a minimum delay, and at the same time, it can improve the reliability of the antenna weight for the data demodulation.

摘要： An uplink radio resource allocation method allocates, at a radio base station, an uplink radio resource used for uplink user data transmission to a mobile station. The method includes: allocating, at the radio base station, the uplink radio resource, so that total received power in an particular cell of the radio base station is equal to a first target value assigned by a radio network controller; and allocating, at the radio station, the uplink radio resource, so that a ratio of first received power from a serving mobile station to second received power from a non-serving mobile station is equal to a second target value assigned by the radio network controller, a serving cell of the serving mobile station being the particular cell, a non-serving cell of the non-serving mobile station being the particular cell.
