    Abstract: A method for receiving system information, a method for transmitting system information by a Node B in a mobile communication system, a user equipment (UE) for receiving system information, and a Node B for transmitting system information by a Node B in a mobile communication system are provided. The method for receiving system information includes receiving system information comprising first partial bits of a system frame number (SFN) on a broadcast channel in a first subframe of a radio frame within a broadcast channel transmission period, the first partial bits having the same value during one broadcast channel transmission period comprising a plurality of radio frames; acquiring second partial bits of the SFN based on decoding the broadcast channel, the second partial bits having different values for different radio frames within the broadcast channel transmission period; and determining the SFN from the first partial bits and the second partial bits.

    Abstract: Methods and apparatuses are described for transmitting acknowledgement information in a communication system. A method includes receiving one or more data TBs in one or more downlink data channels over TTIs; obtaining acknowledgement information comprising four acknowledgement information bits {0, 0, 0, 0}, jointly representing a state of reception results for a plurality of data TBs, wherein a number of the plurality of data TBs is greater than a number of the acknowledgement information bits, a UE is configured for reception of the one or more downlink data channels from two cells, and a number of the TTIs is three or four; Reed-Mueller (RM) encoding the acknowledgement information bits; and transmitting the RM encoded acknowledgement information bits on an uplink data channel. The state of reception results is represented as {NACK, any, any, any} and {NACK/DTX, any, any, any} for a first cell and a second cell of the two cells, respectively, or is represented as {NACK, any, any} and {NACK/DTX, any, any} for the first cell and the second cell, respectively, by the acknowledgement information bits {0, 0, 0, 0}.
