A method for performing sub-channel selective access by a station (STA) in a wireless LAN (WLAN) system includes: receiving a predetermined frame from an access point (AP); selecting at least one sub-channel when the predetermined frame includes channel list information for the sub-channel selective access, bandwidth information for the sub-channel selective access, and time information for the sub-channel selective access; and operating on the selected at least one sub-channel. | 2014-03-27 |
20140086201 | USER TERMINAL, RADIO BASE STATION, DOWNLINK CONTROL CHANNEL RECEIVING METHOD AND MOBILE COMMUNICATION SYSTEM - The present invention is designed such that it is possible to optimize the effect of improving the efficiency of use of radio resources even when the number of user terminals to be multiplexed over the same radio resources is further increased. A user terminal performs downlink communication with a radio base station using a PDCCH resource region and a PDSCH resource region. The user terminal detects the starting position of the radio resources where the PDSCH and the PDCCH are frequency-division-multiplexed in the PDSCH resource region in the time direction, and receives the PDCCH that is frequency-division-multiplexed over the radio resources starting from the detected starting position. | 2014-03-27 |
20140086202 | RADIO BASE STATION APPARATUS, USER TERMINAL APPARATUS, RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD - To provide a radio base station apparatus that enables the effect of improving usage efficiency of radio resources to be exerted sufficiently also in the case where the number of user terminals multiplexed into the same radio resources further increases, the radio base station apparatus performs communications using a first resource region for a downlink control channel subjected to time division, and a second resource region for a downlink data channel, and is characterized by being provided with generation sections ( | 2014-03-27 |
20140086203 | Methods and Arrangements for Transmitting and Receiving Sub-Frame Specific Power Offset Information - In one embodiment, a method in a network node is provided. The network node is configured to use a first power level for transmitting data in subframes of a first type, and to use a second power level for transmitting data in subframes of a second type. The method comprises signaling ( | 2014-03-27 |
20140086204 | SCHEDULING METHOD IN A SHORT DISTANCE WIRELESS PERSONAL AREA NETWORK - The present invention relates to a method of allocating a transmission band to a terminal in a Wireless Personal Area Network (WPAN). The method includes: determining an allocation period of a transmission band on the basis of characteristic information that a terminal has; transmitting a transmission band request to a WPAN coordinator; and receiving information relating to the transmission band allocation from the WPAN coordinator. The transmission band request includes the allocation period of the transmission band determined by the terminal; and the transmission band allocation is determined based on the transmission band allocation period determined by the terminal. | 2014-03-27 |
20140086205 | BASE STATION AND METHOD OF ALLOCATING RADIO RESOURCE - A radio resource allocating section sets a transmission frequency bandwidth of a known signal transmitted from each communication terminal communicating with a communication section to the smallest one of a plurality of bandwidths. The radio resource allocating section allocates, to a communication terminal which transmits the known signal in an uplink communication period included in a unit period, a downlink radio resource including a frequency band included in the transmission frequency band of the known signal in a frequency direction and including a plurality of downlink communication periods included in the unit period in a time direction as a use downlink radio resource. | 2014-03-27 |
20140086206 | BASE STATION - A scheduling executing section calculates a predicted value of a transmission gain at a time when controlling transmission directivity in a plurality of antennas based on a known signal to be received in a frequency band of a use downlink radio resource and performing downlink communication with a communication terminal, and determines a communication terminal to which the use downlink radio resource is allocated based on the predicted value. | 2014-03-27 |
