摘要： An apparatus is capable of transmitting information via an uplink control channel in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system. Uplink control information is encoded to obtain a predetermined bit string. A signal sequence corresponding to the predetermined bit string is generated. The signal sequence is cyclic-shifted according to a predetermined rule. The cyclic-shifted signal sequence is controlled according to a subframe length. Therefore, reception performance deterioration of an uplink control channel allocated to an irregular subframe can be minimized.

摘要： A Handover apparatus and method of a Mobile Station (MS) in a wireless communication system in which at least one small cell resides in a macro cell includes, when entering a neighboring small cell, checking a movement speed of the MS. The method also includes determining whether to hand over to the small cell by taking into account the movement speed of the MS. When it is determined not to hand over to the small cell, that MS transmits small cell penetration information to a macro Base Station (BS); allocates a macro only resource from the macro BS; and communicates with the macro BS in the small cell using the macro only resource allocated from the macro BS.
