The UE450includes a controller/processor490, a data source/buffer480, a receiving processor452, a transmitting processor455, and a transmitter/receiver456including an antenna460.

The base station400may include a controller/processor440, a data source/buffer430, a receiving processor412, a transmitting processor415, a transmitter/receiver416including an antenna420.

In Downlink (DL), an upper-layer packet, for example, higher-layer information carried in the second radio signal and higher-layer information carried in the first signaling and the third signaling (in case the first signaling and the third signaling carry higher-layer information) in the disclosure are provided to the controller/processor440. The controller/processor440provides functions of L2 layer 2 and above L2 layer. In DL, the controller/processor440provides header compression, encryption, packet segmentation and reordering, multiplexing between a logical channel and a transport channel, and a radio resource allocation for the UE450based on various priority metrics. The controller/processor440is also in charge of HARQ operation, retransmission of lost packets, and signalings to the UE450, for example, higher-layer information carried in the second radio signal and higher-layer information carried in the first signaling and the third signaling (in case the first signaling and the third signaling carry higher-layer information) in the disclosure are generated in the controller/processor440. The transmitting processor415performs various signal processing functions used for Layer 1 (that is, PHY), including encoding, interleaving, scrambling, modulation, power control/allocation, precoding, and generation of physical layer control signalings, etc. Physical layer signals of the second radio signal, the first signaling and the third signaling in the disclosure are generated at the transmitting processor415, the generated modulated symbols are split into parallel streams and each stream is mapped to corresponding multicarrier subcarriers and/or multicarrier symbols, and then the transmitting processor415maps it to the antenna420via the transmitter416to transmit out in form of Radio Frequency (RF) signal. At the receiving terminal, each receiver456receives an RF signal via the corresponding antenna460; each receiver454recovers the baseband information modulated onto the RF carrier and provides the baseband information to the receiving processor452. The receiving processor452performs various signal receiving processing functions used for L1 layer. The signal receiving processing functions include reception of physical layer signals of the second radio signal, the first signaling and the third signaling in the disclosure, etc.; multicarrier symbols in the multicarrier symbol streams are demodulated corresponding to different modulation schemes (for example, BPSK and QPSK), and then are descrambled, decoded and deinterleaved to recover the data or control signals on a physical channel transmitted by the first communication node400, then the data and control signals are provided to the controller/processor490. The controller/processor490implements functions of L2 layer and above L2 layer, and the controller/processor490interprets the higher-layer information carried in the second radio signal and the higher-layer information carried in the first signaling and the third signaling (in case the first signaling and the third signaling carry higher-layer information) in the disclosure. The controller/processor may be connected to a memory480that stores program codes and data. The memory480may be a computer readable medium.

In Uplink (UL) transmission, the data source/buffer480provides higher-layer data to the controller/processor490. The data source/buffer480illustrates all protocol layers of and above the L2 layer. The controller/processor490provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation of the base station400so as to provide the functions of L2 layer used for the control plane and user plane. The controller/processor490is also in charge of HARQ operation, retransmission of lost packets, and signalings to the base station400. Higher-layer data carried in the first radio signal and higher-layer data carried in the second signaling (when the second signaling carries higher-layer data) in the disclosure are generated at the data source/buffer480or at the controller/processor490. The transmitting processor455performs various signal transmitting processing functions used for L1 layer (that is, PHY); physical layer signals of the first radio signal and the second signaling in the disclosure are generated at the transmitting processor455. The signal transmitting processing function includes encoding and interleaving so as to ensure FEC (Forward Error Correction) at the UE450, and modulation of baseband signals corresponding to different modulation schemes (i.e., BPSK, QPSK, M-PSK M-QAM, etc.). The modulated symbols are split into parallel streams and each stream is mapped to corresponding multicarrier subcarriers and/or multicarrier symbols, and then the transmitting processor415maps it to the antenna460via the transmitter456to transmit out in form of Radio Frequency (RF) signal. The receiver416receives an RF signal via the corresponding antenna420; each receiver416recovers the baseband information modulated onto the RF carrier and provides the baseband information to the receiving processor412. The receiving processor412performs various signal receiving processing functions used for L1 layer, including receiving physical layer signals of the first radio signal and the second signaling in the disclosure, etc.; the signal receiving processing function includes acquiring multicarrier symbol streams, and then demodulating the multicarrier symbols in the multicarrier symbol streams corresponding to different modulation schemes (for example, BPSK and QPSK), and then decoding and deinterleaving to recover the data or control signals on a physical channel transmitted by the UE450, then the data and control signals are provided to the controller/processor440. The controller/processor440implements functions of L2 layer, including interpreting the higher-layer data carried in the first radio signal and the higher-layer data carried in the second signaling in the disclosure (when the second signaling carries higher-layer data). The controller/processor may be connected to the buffer430that stores program codes and data. The buffer430may be a computer readable medium.
