le and bundling is not required. Negative acknowledgements can be transmitted in a subset of subframes for asymmetric uplink/downlink configurations, and there is multiplexing in one of the downlink subframes. The same control channel formats are used for 3GPP LTE TDD and FDD modes. Nevertheless, the interpretation of transmitted bits and assignment of the resources are different. Table 7-2 summarizes the HARQ feedback and UE behavior in the uplink.
