Example 3
Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for the user plane and the control plane according to the present application, as shown in fig. 3. Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for a first type of communication node device (UE) and a second type of communication node device (gNB, eNB or repeater) in three layers: layer 1, layer 2 and layer 3. 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 the PHY301, and is responsible for a link between the first type of communication node device and the second type of communication node device through the PHY 301. In the user plane, the L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second type of communication node device on the network side.

The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, security by ciphering the data packets, and handoff support between communication node devices of the second type to communication node devices of the first type. The RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of packets to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in one cell among the first type of communication node devices. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the first type of communication node device and the second type of communication node device is substantially the same for the physical layer 301 and the L2 layer 305, but without header compression functionality for the control plane. The Control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3 (layer L3). The RRC sublayer 306 is responsible for obtaining radio resources (i.e. radio bearers) and for configuring the lower layers using RRC signaling between the second type of communication node device and the first type of communication node device.

Embodiment 4 shows a schematic diagram of a base station device and a given user equipment according to the present application, as shown in fig. 4. Fig. 4 is a block diagram of a gNB/eNB410 in communication with a UE450 in an access network.
Included in the user equipment (UE450) are a controller/processor 490, a memory 480, a receive processor 452, a transmitter/receiver 456, a transmit processor 455, and a data source 467, the transmitter/receiver 456 including an antenna 460. A data source 467 provides upper layer packets, which may include data or control information such as DL-SCH or UL-SCH, to the controller/processor 490, and the controller/processor 490 provides packet header compression decompression, encryption and decryption, packet segmentation concatenation and reordering, and multiplexing and demultiplexing between logical and transport channels to implement the L2 layer protocol for the user plane and the control plane. The transmit processor 455 implements various signal transmit 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, among others. Receive processor 452 performs various signal receive processing functions for the L1 layer (i.e., the physical layer) including decoding, deinterleaving, descrambling, demodulation, depredialing, and physical layer control signaling extraction, among others. The transmitter 456 is configured to convert baseband signals provided from the transmit processor 455 into radio frequency signals and transmit the radio frequency signals via the antenna 460, and the receiver 456 is configured to convert radio frequency signals received via the antenna 460 into baseband signals and provide the baseband signals to the receive processor 452.

The upper layer packets arrive at controller/processor 440, and controller/processor 440 provides packet header compression decompression, encryption decryption, packet segmentation concatenation and reordering, and multiplexing and demultiplexing between logical and transport channels to implement the L2 layer protocol for the user plane and the control plane. Data or control information, such as a DL-SCH or UL-SCH, may be included in the upper layer packet. The transmit processor 415 implements various signal transmit processing functions for the L1 layer (i.e., physical layer) including coding, interleaving, scrambling, modulation, power control/allocation, precoding, and physical layer signaling (including synchronization and reference signal generation, etc.), among others. The receive processor 412 performs various signal receive processing functions for the L1 layer (i.e., the physical layer) including decoding, deinterleaving, descrambling, demodulation, depredialing, physical layer signaling extraction, and the like. The transmitter 416 is configured to convert the baseband signals provided by the transmit processor 415 into rf signals and transmit the rf signals via the antenna 420, and the receiver 416 is configured to convert the rf signals received by the antenna 420 into baseband signals and provide the baseband signals to the receive processor 412.
In the DL (Downlink), upper layer packets (e.g., the first information block in this application, the upper layer packet carried by the second radio signal, and the upper layer packet carried by each of the X radio signals) are provided to the controller/processor 440. Controller/processor 440 implements the functionality of layer L2. In the DL, the controller/processor 440 provides packet header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the UE450 based on various priority metrics.

The transmit processor 415 implements various signal processing functions for the L1 layer (i.e., the physical layer) including decoding and interleaving to facilitate Forward Error Correction (FEC) at the UE450 and modulation of the baseband signal based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)), as well as generation of L1 layer signaling (such as information about the L1 layer in the second signaling and information about the L1 layer in the X first class of signaling), splitting the modulation symbols into parallel streams and mapping each stream to a respective multi-carrier subcarrier and/or multi-carrier symbol, which are then mapped to the antenna 420 by the transmit processor 415 via the transmitter 416 for transmission as a radio frequency signal. In the present application, each of the first information block, the second wireless signal, and each of the X wireless signals in the corresponding channel of the physical layer is mapped onto a target air interface resource by the transmission processor 415, and mapped onto the antenna 420 via the transmitter 416 to be transmitted in the form of a radio frequency signal. 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 performs various signal receive processing functions at the L1 layer and reception of signaling at the L1 layer.
