A method and apparatus provide a physical uplink channel in resource blocks. Scheduling information can be received. The scheduling information can be to transmit a first physical uplink channel within a slot. The slot can include a plurality of symbols. The slot can include the first physical uplink channel and a second physical uplink channel. The first physical uplink channel can be shorter in duration than the second physical uplink channel. One or more allocated resource blocks for the first physical uplink channel can be determined based on a sub-band group and one or more resource block groups within the sub-band group. The sub-band group can include one or more sub-bands. Each sub-band can include one or more resource block groups. Each resource block group can include one or more resource blocks. A resource block can include one or more contiguous resource elements in the frequency domain. The first physical uplink channel can be transmitted in the determined one or more allocated resource blocks in the slot.
