Method and apparatus for an uplink transmission based on a characteristic of physical resources
The disclosure relates to a pre-fifth-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond fourth-generation (4G) communication system such as long term evolution (LTE). A method of a terminal of a wireless communication system is provided. The method includes receiving information on mapping between at least one logical channel and profile information of at least one uplink grant from a base station, receiving the at least one uplink (UL) grant from the base station, and transmitting data based on the profile information of the at least one uplink grant and the mapping information.

in case that the uplink grant is associated with the second identifier, allocating resources included in the uplink grant to a first logical channel with a higher priority than a second logical channel; and
transmitting data based on the resources,
wherein an error rate for a modulation coding scheme (MCS) level of the uplink grant associated with the second identifier is lower than an error rate for an MCS level of an uplink grant associated with the C-RNTI.

at least one processor configured to:
receive, via the transceiver from a base station, control information including an uplink grant,
identify an identifier of the terminal for decoding the control information, the identifier being identified from a first identifier that is a cell-radio network temporary identifier (C-RNTI) or a second identifier,
in case that the uplink grant is associated with the second identifier, allocate resources included in the uplink grant to a first logical channel with a higher priority than a second logical channel, and
transmit, via the transceiver to the base station, data based on the resources,
wherein an error rate for a modulation coding scheme (MCS) level of the uplink grant associated with the second identifier is lower than an error rate for an MCS level of an uplink grant associated with the C-RNTI.
10. The terminal of claim 9 , wherein the identifier of the terminal for decoding the control information is determined based on a type of the data.
11. The terminal of claim 9 ,
