A resource assignment can be received. A first set of time-frequency resources in a subframe can be determined from the resource assignment. A second set of time-frequency resources in the subframe can be determined. The second set of time-frequency resources can be used for a second latency data transmission. The second set of time-frequency resources can overlap with at least a portion of the first set of time-frequency resources. A first latency data transmission in the subframe can be decoded based on the determined first and second set of time-frequency resources. The first latency transmission can have a longer latency than the second latency transmission.
