A channel coding method of variable length information using block code is disclosed. A method for channel-coding information bits using a code generation matrix including 20 rows and A columns corresponding to length of the information bits includes, channel-coding the information bits having “A” length using basis sequences having 20-bit length corresponding to columns of the code generation matrix. If “A” is 10, individual basis sequences of the code generation matrix correspond to column-directional sequences of a specific matrix composed of 20 rows and 10 columns. The specific matrix is made from 20 rows of the (32,10) code matrix used for TFCI coding were selected.

A method for cooperative control of power among base stations and a base station device which performs the same are discussed. A first receiving unit is configured such that a specific base station in a cooperative unit receives, from a specific terminal located on a cell edge of the specific base station, token value information which indicates an average transmission rate of the specific terminal and the up-to-date level of satisfaction of the minimum average transmission rate of the specific terminal. A second receiving unit receives, from one or more other base stations in the cooperative unit, information containing an average transmission rate of terminals located on edges of each of the base stations, token values of terminals located on cell edges of each of the base stations, and the current power levels of each of one or more base stations.

A method for efficiently transmitting and receiving control information through a Physical Downlink Control Channel (PDCCH) is provided. When a User Equipment (UE) receives control information through a PDCCH, the received control information is set to be decoded in units of search spaces. Here, the UE monitors a UE-specific search space, among the search spaces. The UE-specific search space is given based on a modulus operation using the variable of Yk for the subframe k and a variable C for the subframe k, wherein Yk is defined by: Yk=(A*Yk−1+B) mod D, the variable C is determined based on the number of CCEs (NCCE) divided by the aggregation level (L), and A, B and D are predetermined constant values predetermined regardless of the aggregation levels (L).

A resource allocation method and a method for transmitting resource allocation information in a mobile communication system are disclosed. That is, a LVRB (PRB) and a DVRB which are the units of a scheduling resource are defined and a resource allocation method and a method for transmitting resource allocation information using the same are disclosed. In the LVRB, a part bitmap scheduling method using a LVRB set is suggested and a method for constructing resource allocation information using the same is suggested. In the DVRB, a method for defining the DVRB using PRBs in a subframe is suggested and a method for constructing resource allocation information using the same when scheduling is performed using the DVRB constructed by the defined method is suggested. In order to prevent interference and collision from occurring due to the complete matching of the DVRBs in respective cells, a method using different DVRBs in the respective cells is suggested.

A method for efficiently providing data and a reference signal (RS) when antennas are added to an existing system is provided. The method includes transmitting an RS in a downlink MIMO system that supports a first user equipment (UE) and a second UE, the first UE recognizing four predetermined transmitting antennas among eight transmitting antennas and the second UE recognizing the eight transmitting antennas, generating a subframe that can be recognized by both the first UE and the second UE and transmitting the generated subframe to the first UE and the second UE, where the first UE and the second UE recognize all orthogonal frequency division multiplexing (OFDM) symbols of the subframe.

A method for transmitting information of resources for use in transmission of ACK/NACK signals in a mobile communication system is disclosed. An example method for receiving ACK/NACK signals in a mobile communication system is also disclosed. When resources for transmission of data and resources for transmission of control information of the data are scheduled through virtual unit resources, the method identifies information of resources for receiving an ACK/NACK signal for transmission data mapped to information of at least one of a virtual unit resource allocated to the transmission data and a virtual unit resource allocated to control information of the transmission data, and receives the ACK/NACK signal for the transmission data through the information of resources for receiving the ACK/NACK signal.

A method for a user equipment to perform random access to a base station in a wireless communication system that supports multiple uplink and downlink carriers is provided. In the method, system information including cell identifier information of each of the downlink component carriers and PRACH TF slot and preamble sequence information which is common to all downlink component carriers, the system information being broadcast through each downlink component carrier corresponding to the cell identifier information, is received. A PRACH preamble is transmitted through one uplink component carrier linked to the downlink component carriers using the received PRACH TF slot and preamble sequence information. An RACH response is received through each of the downlink component carriers. The cell identifier information is used to transmit a Radio Resource Control (RRC) connection request signal and cell identifier information of a downlink component carrier, which the user equipment desires to access among the downlink component carriers.
摘要:
In a mobile communication system, an error detection code or a quality frame indicator (e.g., CRC) is generated using selectively frame information, and at least one of a WCA identifier of another terminal, and a corresponding terminal identifier. And the terminal identifier can be implicitly transmitted to the receiver.
