Provided are a method and device for ranging in a wireless communication system. A machine-to-machine (M2M) device receives an advanced air interface-system configuration descriptor (AAI-SCD) message including information on a dedicated ranging channel for the M2M device and an M2M parameter change count from a base station, and attempts ranging through the dedicated ranging channel to the base station. At this point, the M2M parameter change count orders information on the dedicated ranging channel in the AAI-SCD message to change.

Disclosed are a method for receiving control information and a terminal device using the same. The terminal is able to receive a non-user-specific A-MAP IE of a specific sub-frame from a base station according as a broadcasting message is transmitted from the specific sub-frame, wherein the non-user-specific A-MAP IE includes an indicator showing that the non-user-specific A-MAP IE is configured in an extended form. The terminal can also obtain scheduling information based on the received indicator, wherein the scheduling information is configured by the type of the extended non-user-specific A-MAP IE. Then, the terminal is capable of decoding the broadcast message in a certain sub-frame based on the obtained scheduling information.

A method and apparatus for transmitting and receiving system information in a wireless communication system are disclosed. A method for receiving system information by a mobile station (MS) of a wireless communication system includes receiving a secondary superframe header (S-SFH) change cycle from a base station (BS), and receiving a primary superframe header information element (P-SFH IE) including a first field indicating a change count of a plurality of secondary superframe header subpacket information elements (S-SFH SP IEs) from the base station (BS). Once each of the plurality of S-SFH SP IEs is changed, each of the plurality of S-SFH SP IEs remains unchanged during one or more S-SFH change cycles.

摘要:
A signal transmission method for increasing the amount of data transmission is described. When a specific transmitting side transmits signals in a signal transmission mode applied to a low-speed transmitting side, the specific transmitting side reduces the number of times of pilot transmission, thereby efficiently increasing a data transmission rate. The amount of data transmitted through one subchannel is set to be the same. To this end, improved subchannel structure, and improved system parameters in which a guard interval is adjusted are provided.

There are provided a method and apparatus for allocating a sounding channel in a wireless communication system. A base station transmits a first sounding channel allocation data to allocate a first sounding channel for a first system to a first zone, and transmits a second sounding channel allocation data to allocate a second sounding channel for a second system other than the first system to a second zone. The first zone and the second zone are multiplexed by an FDM (Frequency Division Multiplexing) method, and the first sounding channel and the second sounding channel are allocated to a same OFDMA (Orthogonal Frequency Division Multiple Access) symbol. A channel response can be estimated accurately when a terminal for IEEE (Institute of Electrical and Electronics Engineers) 802.16m system and a terminal for IEEE 802.16e system coexist in a legacy support mode.

A method of allocating pilot subcarriers in a resource block for a wideband wireless mobile communication system with multiple transmission antennas using orthogonal frequency division multiplexing (OFDM) modulation is disclosed. In this method, pilot subcarriers are allocated to the resource block comprised of five (5) or seven (7) OFDM symbols so that only four (4) OFDM symbols of the resource block are allocated for pilot subcarriers.

A method and apparatus of transmitting an uplink control signal of a mobile station (MS) in a wireless communication system is provided. A mobile station (MS) receives resource allocation information of a first uplink control channel for transmitting an uplink synchronization signal and resource allocation information of a second uplink control channel. The MS allocates a first uplink control channel resource and a second uplink control channel resource to the first uplink control channel and the second uplink control channel respectively based on the resource allocation information of the first uplink control channel and the resource allocation information on the second uplink control channel and transmits an uplink control signal through at least one of the first uplink control channel and the second uplink control channel to a base station. The first uplink control channel resource is located in a first resource unit among a plurality of resource units constituting a logical resource region, and the first uplink control channel resource and the second uplink control channel resource are allocated in that order in the logical resource region.
