A method for wireless communication, comprising: transmitting or receiving, by a base station, to or from a first user equipment, UE, a first data transmission over a first self-contained partition of a carrier frequency range supporting a first air interface configuration, characterized in that: the first self-contained partition of the carrier frequency range includes a first physical data channel and all physical control channel signaling for decoding data carried in the first physical data channel within a first bandwidth of the first self-contained partition, before the transmitting or receiving, the method further comprises sending, by the base station, to the first UE, a first initial access information over an anchor partition of the carrier frequency range, wherein the first initial access information indicates self-contained partitions comprising the first self-contained partition, the first self-contained partition excludes the first initial access information transmitted to the first UE, and the first self-contained partition is assigned to the first UE without the base station transmitting or receiving the first data transmission and all physical control channel signaling for decoding the data carried in the first data transmission in frequencies in the carrier frequency range that are outside the first self-contained partition. transmitting or receiving, by a base station, to or from a first user equipment, UE, a first data transmission over a first self-contained partition of a carrier frequency range supporting a first air interface configuration, characterized in that: the first self-contained partition of the carrier frequency range includes a first physical data channel and all physical control channel signaling for decoding data carried in the first physical data channel within a first bandwidth of the first self-contained partition, before the transmitting or receiving, the method further comprises sending, by the base station, to the first UE, a first initial access information over an anchor partition of the carrier frequency range, wherein the first initial access information indicates self-contained partitions comprising the first self-contained partition, the first self-contained partition excludes the first initial access information transmitted to the first UE, and the first self-contained partition is assigned to the first UE without the base station transmitting or receiving the first data transmission and all physical control channel signaling for decoding the data carried in the first data transmission in frequencies in the carrier frequency range that are outside the first self-contained partition. the first self-contained partition of the carrier frequency range includes a first physical data channel and all physical control channel signaling for decoding data carried in the first physical data channel within a first bandwidth of the first self-contained partition, before the transmitting or receiving, the method further comprises sending, by the base station, to the first UE, a first initial access information over an anchor partition of the carrier frequency range, wherein the first initial access information indicates self-contained partitions comprising the first self-contained partition, the first self-contained partition excludes the first initial access information transmitted to the first UE, and the first self-contained partition is assigned to the first UE without the base station transmitting or receiving the first data transmission and all physical control channel signaling for decoding the data carried in the first data transmission in frequencies in the carrier frequency range that are outside the first self-contained partition.
