Description

A wireless communication method and device Technical Field

[0001] The present application relates to methods and devices in wireless communication systems, and more particularly to methods and devices for wireless signal transmission in wireless communication supporting cellular networks. Background Art

[0002] The application scenarios of future wireless communication systems are becoming increasingly diverse, and different scenarios place varying performance requirements on the systems. To meet these diverse performance demands, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) plenary meeting #72 decided to conduct research on New Radio (NR) (or 5G). The 3GPP RAN plenary meeting #75 approved the WI (Work Item) for New Radio, initiating standardization work on NR.

[0003] RIS (Reconfigurable Intelligent Surface) is an artificial electromagnetic surface structure with programmable electromagnetic properties, consisting of a large number of independent, low-cost, passive subwavelength resonant units. Each RIS unit has independent electromagnetic wave control capabilities, and its response to wireless signals, such as phase, amplitude, and polarization, can be controlled by changing its parameters and spatial distribution. By superimposing the wireless response signals of a large number of RIS units, specific beam propagation characteristics are formed on a macro scale, thereby forming a flexible and controllable shaped beam, achieving the effects of eliminating coverage blind spots, enhancing edge coverage, and increasing the rank of multi-stream transmission. RIS technology is characterized by low cost, low energy consumption, programmability, easy deployment, and high shaping gain achieved with larger antenna scales. It is considered a key technology for 5G Advanced research and one of the core visions of 6G.

Furthermore, adopting a unified solution for different scenarios can also help reduce hardware complexity and cost.

[0218] Example 3

[0219] Embodiment 3 illustrates a schematic diagram of the radio protocol architecture for the user plane and control plane according to one embodiment of the present application, as shown in FIG3 . FIG3 is a schematic diagram illustrating an embodiment of the radio protocol architecture for the user plane 350 and control plane 300. FIG3 illustrates the radio protocol architecture for the control plane 300 of the UE and gNB using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1) 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) 305, located above PHY 301, is responsible for the link between the UE and gNB via PHY 301. L2 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304. These sublayers terminate at the gNB on the network side. The PDCP sublayer 304 provides data encryption and integrity protection and also supports UE mobility between gNBs. The RLC sublayer 303 provides packet segmentation and reassembly, enabling retransmission of lost packets through ARQ (Automatic Repeat Request). The RLC sublayer 303 also provides duplicate packet detection and protocol error detection. The MAC sublayer 302 provides mapping between logical and transport channels and logical channel multiplexing. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell between UEs.

The wireless protocol architecture of the user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The wireless protocol architecture in the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce wireless transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for mapping QoS flows and data radio bearers (DRBs) to support service diversity. The UE's radio protocol architecture in the user plane 350 may include the SDAP sublayer 356, the PDCP sublayer 354, some or all of the RLC sublayer 353 and the MAC sublayer 352 at the L2 layer. Although not shown, the UE may also have several upper layers above the L2 layer 355, including a network layer (e.g., an IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., a remote UE, server, etc.).

[0231] Example 4

[0232] Embodiment 4 illustrates a hardware module diagram of a communication device according to an embodiment of the present application, as shown in FIG4. FIG4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0233] The first communication device 450 includes a controller / processor 459 , a memory 460 , a data source 467 , a transmit processor 468 , a receive processor 456 , a multi-antenna transmit processor 457 , a multi-antenna receive processor 458 , a transmitter / receiver 454 and an antenna 452 .

[0234] The second communication device 410 includes a controller / processor 475 , a memory 476 , a data source 477 , a receive processor 470 , a transmit processor 416 , a multi-antenna receive processor 472 , a multi-antenna transmit processor 471 , a transmitter / receiver 418 and an antenna 420 .

[0235] During transmission from the second communications device 410 to the first communications device 450, at the second communications device 410, upper layer data packets from the core network or from a data source 477 are provided to a controller / processor 475. The core network and data source 477 represent all protocol layers above the L2 layer. The controller / processor 475 implements L2 layer functionality. During transmission from the second communications device 410 to the first communications device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communications device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets and signaling to the first communications device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, as well as mapping of signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), and M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream, and then provides it to a different antenna 420.

[0236] During transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal via its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the RF carrier and converts the RF stream into a baseband multi-carrier symbol stream, which is provided to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various L1 signal processing functions. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multi-carrier symbol stream, after the receive analog precoding / beamforming operations, from the time domain to the frequency domain using a fast Fourier transform (FFT). In the frequency domain, the receive processor 456 demultiplexes the physical layer data signal and reference signal, where the reference signal is used for channel estimation. The data signal undergoes multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on the physical channel. The upper layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. During transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 provides multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover higher layer data packets from the second communication device 410. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 layer for L3 processing.

[0237] During transmission from the first communications device 450 to the second communications device 410, upper layer data packets are provided to the controller / processor 459 at the first communications device 450 using a data source 467. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functionality at the second communications device 410 described in the transmission from the second communications device 410 to the first communications device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels, implementing L2 layer functions for both the user plane and the control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the second communications device 410. The transmit processor 468 performs modulation mapping and channel coding, while the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming. The transmit processor 468 then modulates the resulting spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding and beamforming operations in the multi-antenna transmit processor 457, the stream is provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a RF symbol stream before providing it to the antenna 452.

[0238] During transmission from the first communication device 450 to the second communication device 410, the functionality at the second communication device 410 is similar to the reception functionality at the first communication device 450 described for transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives RF signals via its corresponding antenna 420, converts the received RF signals into baseband signals, and provides the baseband signals to the multi-antenna receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement the L1 layer functionality. The controller / processor 475 implements the L2 layer functionality. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as a computer-readable medium. During transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the first communication device 450. The controller / processor 475 may provide upper layer data packets to the core network or all protocol layers above the L2 layer, and may also provide various control signals to the core network or L3 for L3 processing.
