    摘要: An apparatus and method for efficiently transmitting/receiving a control channel in a mobile communication system simultaneously supporting a synchronous High-Rate Packet Data (HRPD) system and an Orthogonal Frequency Division Multiplexing (OFDM) system. Power of a control channel to be transmitted is measured. The measured power is compared with marginal maximum power set by a higher layer. According to the comparison result, information indicating whether a previous reverse packet has been successfully received and power control information for controlling power of a reverse link is inserted and transmitted in at least one of a Medium Access Control (MAC) channel and an OFDM symbol.

    摘要: A method for transmitting/receiving resource allocation information in a mobile communication system using a shared control channel. The transmission method includes performing scheduling for resource allocation to a plurality of terminals; generating, in a bitmap, information indicating allocation/non-allocation of resources which are not sequentially allocated beginning from a particular terminal using the scheduling result; and transmitting, over the shared control channel, resource allocation information including a terminal identifier and a resource allocation bitmap of each terminal. The reception method includes receiving from a wireless network a shared control channel including resource allocation information; determining whether a terminal identifier included in the resource allocation information is equal to a terminal identifier of the terminal; and updating a size of an available resource set according to a resource allocation bitmap for reception of next resource allocation information, if the included terminal identifier is not equal to the terminal identifier of the terminal.

    摘要: In an apparatus for controlling reply signal transmission in a reply signal transmitter that generates and transmits a reply signal according to an error check in packet data received through a radio channel in a mobile communication system, an error detection part generates a reply signal corresponding to the error check from the packet data received through the radio channel. A spreading part spreads the reply signal to output the spread reply signal. A transmission power control part carries out a power control operation for the spread reply signal with a power value that differs according to a packet data transmission rate of a packet data channel. A transmission part transmits the reply signal outputted by the transmission power control part through a radio channel.

    摘要: A Channel Quality Indicator (CQI) expression and feedback method prevents an excessive increase in the CQI feedback overhead while supporting both Single-User MIMO and Multi-User MIMO operations. When a default MIMO operation is set to Single-User MIMO or Multi-User MIMO, an access network can receive MIMO CQI feedback optimized for the corresponding MIMO operation. However, when a scheduler has selected an alternative MIMO operation other than the default MIMO operation, the access network calculates a CQI necessary for the alternative MIMO operation based on the default MIMO CQI feedback for the default MIMO operation and the DELTA CQI feedback for the alternative MIMO operation. In this manner, the invention enables the best operation in the default MIMO operation by providing a correct CQI, and enables the second best operation in the alternative MIMO operation. With use of the invention, the access network can dynamically select the Single-User MIMO and Multi-User MIMO operations, contributing to an increase in the resource management efficiency.

    摘要: A method for transmitting/receiving a data control channel in a wireless communication system that transmits packet data. The transmission method includes transmitting packet data over a packet data channel, transmitting a control channel and receiving an ACKnowledgement (ACK) signal from a terminal that has received the control channel. The reception method includes receiving packet data and a control channel, acquiring control information by demodulating the control channel, and detecting an error in the control channel, and sending the error detection result to a base station as an ACK signal, if the control channel has been transmitted to the terminal itself.
