Lte hierarchical burst mode

Methods, systems, and devices for communicating in a wireless communication system, the layer structure will be described. eNB and / or the UE, a radio that is at least in part defined by the second layer by the second layer transmission having a first layer and a second sub-frame type by the first layer, the transmission having a first sub-frame type It may be configured to operate within a communication system. A first sub-frame type, and may have a first round trip time (RTT) between the reception of the transmission confirmation and the transmission response, the second layer may have a second smaller than the first RTT RTT. A first sub-frame of the sub-frame type are, for example, through time-division multiplexing can be multiplexed with the second sub-frame of sub-frame types.
