Abstract
Disclosed is an apparatus and a method for effectively allocating frequency resources in a mobile communication system. The method includes: determining a first offset of a preset frequency band from among all frequency bands, determining a second offset corresponding to a symbol unit in the preset frequency band, and allocating frequency resources to data, the frequency resources corresponding to a sum of the first offset and the second offset.

An apparatus for transmitting a sub-channel signal in a mobile communication system, the apparatus comprising:
- a sub-channel allocator for allocating a sub-channel for transmission of data in accordance with permuted positions at which the data is stored, and providing the data to the sub-channel for transmission of the data through the sub-channel in each time period unit;
- and
- a transmitter for transmitting the sub-channel signal from the sub-channel allocator;
- wherein the sub-channel allocator comprises:
- a first buffer for storing the data at permuted positions according to a control;
- a permutation unit for permuting positions at which the data will be stored in the first buffer;
- a sub-channel allocating unit for allocating a sub-channel for transmitting the data of the permuted positions, and controlling the data of the permuted positions to be stored in a second buffer, so that the data of the permuted positions can be transmitted through the sub-channel in each time period unit;
- and
- the second buffer for storing the data of the permuted positions by control of the sub-channel allocating unit.
An apparatus for transmitting a sub-channel signal in a mobile communication system, the apparatus comprising:
- a permuter unit for, when data to be transmitted are input, permuting the data and then transferring a data address for the permuted data;
- a packet buffer for storing the data at the data address transferred from the permuter;
- a symbol buffer for storing the data transferred from the packet buffer in each time period unit;
- and
- a sub-channel allocator for allocating each sub-channel for transmission of the data of the packet buffer, and controlling the data of the packet buffer to be stored in the symbol buffer, so that the data can be transmitted through the sub-channel in each time period unit;
- wherein the address of the data in the packet buffer in each symbol time period unit corresponds to a sum of an entire offset for sub-channels to be allocated to each band and a data offset within the sub-channel, and the sub-channel allocator performs allocation of sub-carriers within the sub-channel area through addresses obtained by using a set allocation beginning position and the number of sub-channels to be allocated during allocation area and sub-channel indexing.
A method for transmitting a sub-channel signal in a mobile communication system, the method comprising the steps of:
- (1) permuting data and then storing the permuted data at a data address for the permuted data, when data to be transmitted are input;
- (2) allocating a sub-channel for transmitting the permuted data;
- and
- (3) storing the sub-channel for each time period unit so that the permuted data can be transmitted through the sub-channel;
- wherein step (3) comprises the sub-steps of:
- (a) calculating a sub-channel area to be allocated for a current single symbol time period in a sub-band;
- (b) performing sub-channel indexing for area allocation and data allocation;
- (c) obtaining an address for the permuted data and addresses for sub-carriers within the sub-channel area;
- and
- (d) allocating the data of the permuted data address to sub-carriers within the sub-channel area by using the address of the sub-carrier.
