  • Method and apparatus for sending and receiving control channel in wireless communication system
    Patent number: 10715294
    Abstract: In a wireless communication system, a control channel is required in order to use limited resources effectively. However, the control channel resource is part of the system overhead, and thus reduces the data channel resource used for data transmission. In the long term evolution (LTE) system based on OFDM, one sub frame the consists of fourteen OFDM symbols wherein a maximum of three OFDM symbols are used for the control channel resource and remaining eleven OFDM symbols are used for the data channel resource. Therefore, the quantity of energy that can be transmitted for the control channel resource is extremely limited compared to the data channel resource. For this reason, the coverage of the control channel becomes less than that of the data channel, and even if a user can successfully receive the data channel, reception failure of a control channel sometimes results in failure of data recovery.
