Layer 1(L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY 301. Layer 2(L2 layer) 305 is above PHY301 and is responsible for the link between the first node device and the second node device through PHY 301.

In the DL (Downlink), upper layer information carried by upper layer packets, such as the first information block and the first PDSCH in this application, is provided to the controller/processor 440. Controller/processor 440 performs the functions of layer L2 and above. In the DL, a controller/processor 440 provides packet header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to a first node device 450 based on various priority metrics. The controller/processor 440 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first node device 450, such as the higher layer information included in the first information block and carried by the first PDSCH in this application, all generated in the controller/processor 440. The transmit processor 415 implements various signal processing functions for the L1 layer (i.e., physical layer), including coding, interleaving, scrambling, modulation, power control/allocation, precoding, and physical layer control signaling generation, such as generation of the physical layer signal for the first PDCCH, the physical layer signal for the first PDSCH, and the physical layer signal carrying the first information block in this application is done at the transmit processor 415. The generated modulation symbols are divided into parallel streams and each stream is mapped to a corresponding multi-carrier subcarrier and/or multi-carrier symbol and then transmitted as radio frequency signals by a transmit processor 415 via a transmitter 416 to an antenna 420. On the receive side, each receiver 456 receives a radio frequency signal through its respective antenna 460, and each receiver 456 recovers baseband information modulated onto a radio frequency carrier and provides the baseband information to a receive processor 452. The receive processor 452 implements various signal receive processing functions of the L1 layer. The signal reception processing functions include reception of the first PDCCH, the first PDSCH and the physical layer signals carrying the first information block in this application, demodulation based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)) over multicarrier symbols in a multicarrier symbol stream, followed by descrambling, decoding and deinterleaving to recover data or control transmitted by the second node device 410 over the physical channel, followed by providing the data and control signals to the controller/processor 490. The controller/processor 490 is responsible for the L2 layer and above, and the controller/processor 490 interprets the higher layer information included in the first information block and the higher layer information carried by the first PDSCH in this application. The controller/processor can be associated with a memory 480 that stores program codes and data. Memory 480 may be referred to as a computer-readable medium.

In Uplink (UL) transmission, similar to downlink transmission, the higher layer information is generated by the controller/processor 490 and then passes through the transmit processor 455 to implement various signal transmission processing functions for the L1 layer (i.e., physical layer), and the first PUCCH in this application is generated by the transmit processor 455 and then mapped to the antenna 460 via the transmitter 456 and transmitted in the form of a radio frequency signal by the transmit processor 455. The receivers 416 receive the radio frequency signals through their respective antennas 420, each receiver 416 recovers baseband information modulated onto a radio frequency carrier, and provides the baseband information to the receive processor 412. The receive processor 412 performs various signal receive processing functions for the L1 layer (i.e., the physical layer), including receive processing of the first PUCCH in this application, and then provides data and/or control signals to the controller/processor 440. Implementing the functions at the L2 level at the controller/processor 440 includes interpreting higher-level information. The controller/processor can be associated with a buffer 430 that stores program codes and data. Buffer 430 may be a computer-readable medium.
