摘要:
A method and system are provided for controlling uplink transmission power in a wireless communication system. At least one of a plurality of downlink carriers and a plurality of uplink carriers are aggregated, and the plurality of downlink carriers and the plurality of uplink carriers are mapped between a User Equipment (UE) and a network in the wireless communication system. A message relating to uplink carrier transmission power is received at the UE from the network via a downlink carrier. Uplink transmission power of one or more uplink carriers is controlled in accordance with the message and aggregation and mapping of at least one of the downlink carrier and the one or more uplink carriers.

A method for transmitting uplink data using multiple carriers by a User Equipment (UE) in a mobile communication system is provided. The method includes determining a first maximum transmission power indicating a maximum transmission power for each carrier and a second maximum transmission power indicating a maximum transmission power for all carriers based on information for setting transmission power, received from an evolved Node B (eNB), determining a minimum value from among a required transmission power and the first maximum transmission power as an uplink transmission power, for each carrier, scaling the determined uplink transmission powers so that a sum of the uplink transmission powers is less than or equal to the second maximum transmission power, and transmitting the uplink data based on the scaled uplink transmission powers.

A method and apparatus are provided for transmitting and receiving System Information (SI) in a mobile communication system. The method for receiving the SI by a User Equipment (UE) includes receiving, by the UE, at a fixedly scheduled sub-frame of a predetermined radio frame within a Primary Broadcast CHannel (P-BCH) transmission period, the SI including first partial bits of a System Frame Number (SFN), the first partial bits indicating a repeated value; and acquiring, by the UE, second partial bits of the SFN in the predetermined radio frame by decoding the P-BCH, the second partial bits indicating a different value.
摘要:
A method and apparatus for transmitting and receiving system information in a mobile communication system are provided, in which a System Frame Number (SFN) is transmitted as system information, and other system information, which excludes the SFN, is transmitted using resources different from resources used to transmit the SFN on a broadcast channel.

A method and apparatus for transmitting/receiving pilot symbols for demodulation of control channel information in the uplink of a wireless communication system are provided. When an Evolved Node B (ENB) expects to receive both the Channel Quality Information (CQI) and the Acknowledgement (ACK)/Negative ACK (NACK) from a User Equipment (UE) in a certain subframe, if the UE transmits only the CQI channel, the ENB is prevented to detect the nonexistent ACK/NACK information from the CQI channel, thereby avoiding false alarm.

A method and apparatus for transmitting/receiving paging information in a wireless communication system having a system bandwidth being an integer multiple of a minimum reception bandwidth of a User Equipment (UE), in which a system band is divided into frequency bands having a bandwidth equal to the minimum reception bandwidth of the UE, a Paging Indicator (PI) of the paging information is transmitted in each of the frequency bands, the PI including a group identifier (ID) of a group to which the UE belongs, and a paging message of the paging information is transmitted in one of the frequency bands, the paging message including an ID of the UE.

A method for transmitting an uplink control channel at a terminal in a Single Carrier Frequency Division Multiple Access (SC-FDMA)-based mobile communication system is provided. The transmission method includes receiving a control channel index allocated from a base station; transmitting control information at every symbol through a subband and a Zadoff-Chue sequence offset resource, which are mapped to the control channel index according to a first grouping rule; and transmitting control information through a subband and a Zadoff-Chue sequence offset resource, which are mapped to the control channel index according to a second grouping rule, beginning from a symbol after a slot boundary.

An interleaving method to which time-first-mapping is applied in a mobile communication system is provided. The interleaving method includes writing coded bits into an interleaver on a row-by-row basis, and reading the coded bits written in the interleaver on a column-by-column basis, wherein the coded bits are written by groups having a size according to a modulation order.
