The control signaling may include resource assignment within the partition, modulation and coding scheme indication, reference signal configuration and retransmission information. In some embodiments, an anchor partition of a carrier is used to communicate initial access information for self-contained partitions of the carrier. The initial access information may include center-frequencies, bandwidths, and/or air interface configurations of the self-contained partitions. The anchor partition may also carry load indications associated with the self-contained partitions. ## Claims ### Claim 1 A method comprising: transmitting or receiving, by a base station, a first wireless transmission over a first partition of a carrier supporting a first air interface configuration, the first wireless transmission including a first physical data channel and physical control channel signaling for decoding data carried in the first physical data channel at a receiver of the first wireless transmission;
