Method and apparatus for multiplexing uplink channels in wireless cellular communication system

A method of receiving control information in a wireless communication system, the method comprising:

• receiving a control channel including control information based on time-frequency region configured by a higher layer signaling, the control information indicating a number of contiguous frequency resources for a data channel;
• identifying a starting frequency resource for the control channel based on a blind decoding for the control channel;
• identifying a starting frequency resource for the data channel based on the identified starting frequency resource for the control information, wherein the starting frequency resource for the data channel is identified to be the same as the starting frequency resource for the control channel;
• and
• receiving the data channel using resources corresponding to the number of contiguous frequency resources from the starting frequency resource for the data channel.

A transmitting apparatus for transmitting control information in a wireless communication system, the transmitting apparatus comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• transmit a control channel including control information based on time-frequency region configured by a higher layer signaling, the control information indicating a number of contiguous frequency resources for a data channel, and
• transmit the data channel using resources corresponding to the number of contiguous frequency resources from a starting frequency resource for the data channel,
• wherein the starting frequency resource for the data channel is same as a starting frequency resource for the control channel,
• wherein the starting frequency resource for the control channel is identified by a receiving apparatus based on a blind decoding for the control channel, and
• wherein the starting frequency resource for the data channel is identified by the receiving apparatus to be the same as the identified starting frequency resource for the control channel.
