摘要:
An apparatus and method for generating a scrambling code in a radio communication system is disclosed. In particular, an apparatus and method for generating a scrambling code using a Gold-like sequence even when m is a multiple of 4 for a length 2m−1 of a pseudo-random sequence is disclosed. Two LFSRs (LFSR a and LFSR a′) for generating the Gold-like sequence by two different polynomials of degree m are included. The LFSR a′ is constructed by a reciprocal primitive polynomial of the primitive polynomial of degree m over GF(2) used to construct the LFSR a. In order to generate 2m different scrambling codes, one fixed initial value is input to the LFSR a and different initial values of m bits are input to the LFSR a′ according to system-specific information.

A femto cell connection node, a femto cell system, and a data transmission method of the system are disclosed.In the case where a sending terminal is willing to transmit data to a receiving terminal, a femto cell connection node of the sending side determines a present connection state of the receiving terminal and determines a transmission format of the data to be transmitted from the sending terminal to the receiving terminal according to the determined connection state. In particular, in the present disclosure, in the case where the receiving terminal is in a state of being directly or indirectly connectable to an Internet Protocol (IP) network, the data is transmitted to the receiving terminal after changing a protocol portion L1/L2 so that the data may pass through the IP network.

There are provided an apparatus and method for transmitting power headroom information in a multiple component carrier system. The method includes finding Combination Power Headroom (CPH), that is a power headroom, calculated in an User Equipment (UE)-specific way with consideration taken of uplink transmission through a plurality of component carriers configured in the UE, generating CPH information used to inform an evolved NodeB (eNodeB:eNB) of the CPH, and sending the CPH information to the eNB. According to the present invention, power headroom for a combination component carrier is provided to an eNB in a wireless communication system in which a carrier aggregation is used. Accordingly, reliable dynamic carrier aggregation scheduling can be induced, and thus uplink transmission performance can be improved.

A method and apparatus for transmitting information regarding power coordination (PC) by a mobile station (MS) in a multi-component carrier system are provided. The method includes: setting information regarding power coordination (PC) indicating an amount or a range of power which is used to adjust uplink maximum transmission power of the MS, and transmitting the information regarding PC to a base station (BS). The information regarding PC is varied according to the number of component carriers configured in the MS. A scheduling error in the BS due to ambiguity of PC can be reduced and scheduling can be performed adaptively to maximum transmission power of a provided mobile station (MS) or a component carrier.
