摘要： A frequency resource operating apparatus and method for transmitting and receiving data at a different hopping pattern speed according to a CSI in a BWA communication system are provided. In a method of transmitting and receiving data using CSI in a mobile communication system, a BS sets the CSI of an MS to an initial CSI and sends data to the MS according to the initial CSI. The MS sends a downlink CSI to the BS. The BS groups the MS based on the downlink CSI and sends data to the MS according to a hopping pattern for the group of the MS among hopping patterns preset for predetermined groups.

摘要： A subcarrier assignment apparatus and a subcarrier assignment method, in which each of a plurality of Base Stations (BSs) constituting an Orthogonal Frequency Division Multiple Access (OFDMA) communication system provides services in the capacity of a serving BS to Mobile Stations (MSs). Channel quality information for the respective MSs are fed-back from the respective BSs. Subcarriers are assigned to the respective MSs according to a corresponding scheduling scheme in consideration of the channel quality information for the respective MSs, which are fed-back from the respective BSs, and then BSs which manage the subcarriers assigned to the respective MSs according to the corresponding scheduling scheme are selected. These operations provide site diversity to each of the MSs, and thus system capacity is maximized.

摘要： A communication system with a plurality of devices with a communication unit (CU1) arranged to communicate on a first wireless communication channel (CH1), e.g. GSM, in an active mode. Otherwise, the communication unit (CU1) is in an in-active power saving mode. A receiver unit (R1, R2) receives a wake-up signal on a second wireless communication channel (CH2, CH3), e.g. RFID. The receiver unit (R1, R2) then switches the communication unit (CU1) into active mode. The second wireless communication channel (CH2, CH3) is dedicated for wake-up signals and is in a different frequency band than the first wireless communication channel (CH1). Further, the first wireless communication channel (CH1) has a larger distance range than the second wireless communication channel (CH2, CH3). A coordinator device (CD) receives a call on the first wireless communication channel (GSM) and transmits a wake-up signal on the second wireless communication channel (RFID) in order to activate communication units (D1, D2, D3, D4) in a group of the plurality of devices (D1, D2, D3, D4). Hereby power can be saved to the typically more power demanding communication unit (CU1) arranged for long distance communication, while only limited or even zero power is used to monitor for wake-up signals on a short range channel (CH2, CH3). The system is suitable for groups of a plurality of rather closely spaced devices (D1, D2, D3, D4), where one active coordinator device (CD) is used to receive incoming calls on behalf of a group of devices (D1, D2, D3, D4) having their communication units in power saving mode until the coordinator device (CD) activates them.
