| 20100309849 | METHOD OF LOW DUTY MODE OPERATION FOR FEMTO BASE STATION - A method of an efficient low duty mode (LDM) operation for a femto base station is disclosed. The method of a low duty mode (LDM) operation for a femto base station comprises operating at an available interval of a first length according to a default LDM pattern; and operating at an unavailable interval of a second length according to the default LDM pattern, wherein the available interval begins with a frame including a first preamble, the first preamble including information of carrier configuration and system bandwidth. | 12-09-2010 |
| 20110002303 | RANGING BY MOBILE STATION IN FEMTO SYSTEM - A ranging method in a mobile station of a femto system is disclosed. According to the present invention, a femto base station enables non-synchronized ranging channel (NS-RCH) information to be carried on S-SFH SP | 01-06-2011 |
| 20110026419 | METHOD AND APPARATUS FOR CONTROLLING UPLINK POWER IN A WIRELESS COMMUNICATION SYSTEM - A method and apparatus for controlling uplink transmit power in a wireless communication system are disclosed. The method includes determining an uplink transmit power for each of the plurality of transmission channels, and sequentially allocating the determined uplink transmit powers to the transmission channels in a descending order of predetermined priority levels of the transmission channels, within a maximum available transmit power of the user equipment. The priority levels of the transmission channels are predetermined so that control channels, a sounding channel, a data channel, and a bandwidth request channel have priority levels in a descending order. | 02-03-2011 |
