Description

A method and device used in a node for wireless communication Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular to a transmission method and apparatus for wireless signals in a wireless communication system supporting a cellular network. Background Art

[0002] In the existing NR (New Radio) system, spectrum resources are divided into FDD (Frequency Division Duplexing) spectrum and TDD (Time Division Duplexing) spectrum. For TDD spectrum, both the base station and UE (User Equipment) operate in half-duplex mode. This half-duplex mode avoids self-interference and can alleviate the impact of cross-link interference, but it also brings about a decrease in resource utilization and an increase in latency. To address these problems, supporting flexible duplex modes or variable link directions (uplink or downlink or flexible) on TDD spectrum or FDD spectrum has become a possible solution. At the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #88e meeting and the 3GPP Release 18 workshop, support for more flexible duplex modes or full-duplex modes in NR Release 18 received extensive attention and discussion, particularly the subband non-overlapping full-duplex (SBFD) mode on the gNB (NR Node B). In this mode, the same symbol is used for uplink in some frequency resources and for downlink in others, improving resource utilization and reducing latency.

[0003] In traditional wireless communications, UE (User Equipment) reports may include at least one of a variety of auxiliary information, such as CSI (Channel State Information), beam management (Beam Management) related auxiliary information, positioning related auxiliary information, etc. CSI includes at least one of CRI (CSI-RS Resource Indicator, Channel State Information Reference Signal Resource Indicator), RI (Rank Indicator, Rank Indicator), PMI (Precoding Matrix Indicator, Precoding Indicator) or CQI (Channel Quality Indicator). In the NR system, the UE will be configured with resources for channel measurement and resources for interference measurement to obtain channel measurement and interference measurement for calculating CSI.

[0004] Summary of the Invention

[0005] The inventors have discovered through research that how to allocate resources for obtaining interference measurements required for calculating CSI is a problem that needs to be solved.

[0006] In response to the above problems, the present application discloses a solution. It should be noted that, although the above description uses more flexible duplex mode, full-duplex mode and SBFD scenarios as examples, the present application can also be applied to other duplex mode scenarios. Furthermore, adopting a unified design scheme for different scenarios (including but not limited to more flexible duplex mode, full-duplex mode, SBFD mode, half-duplex mode, and traditional duplex mode) can also help reduce hardware complexity and cost. In the absence of conflict, the embodiments and features in the embodiments of any node of the present application can be applied to any other node.

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 communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets, and provides support for inter-zone mobility of the first communication node device between the second communication node devices. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data 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 a cell between the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring lower layers using RRC signaling between the second communication node device and the first communication node device. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture for the first communication node device and the second communication node device 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. However, the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio 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 between QoS flows and data radio bearers (DRBs) to support service diversity. Although not shown in the figure, the first communication node device may 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, a server, etc.).

[0388] Example 4

[0389] Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of the present application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0390] The first communications device 410 includes a controller / processor 475 , a memory 476 , 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 .

[0391] The second 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 .

[0392] In transmission from the first communications device 410 to the second communications device 450, at the first communications device 410, upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements the functionality of the L2 layer. In the DL, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and allocation of radio resources to the second communications device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the second 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 450, as well as constellation mapping based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing on the coded and modulated symbols to generate one or more parallel The transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols 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 multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multi-carrier 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, which is then provided to a different antenna 420.

[0393] During transmission from the first communications device 410 to the second communications device 450, each receiver 454 receives a signal at the second communications device 450 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 physical layer data signal and reference signal are demultiplexed by the receive processor 456, 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 parallel streams destined for the second communications device 450. The symbols on each parallel 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 first 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. In the DL (Downlink), the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the core network. 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. The controller / processor 459 is also responsible for error detection using an acknowledgement (ACK) and / or negative acknowledgement (NACK) protocol to support HARQ operations.

[0394] During transmission from the second communications device 450 to the first communications device 410, at the second communications device 450, a data source 467 is used to provide upper layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit functionality at the first communications device 410 described in the DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communications device 410, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first 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 parallel streams into multi-carrier / single-carrier symbol streams. After analog precoding and beamforming operations in the multi-antenna transmit processor 457, these streams are 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.

[0395] During transmission from the second communication device 450 to the first communication device 410, the functionality at the first communication device 410 is similar to the reception functionality at the second communication device 450 described for transmission from the first communication device 410 to the second 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 L1 layer functionality. The controller / processor 475 implements L2 layer functionality. The controller / processor 475 may be associated with a memory 476 storing program code and data. The memory 476 may be referred to as a computer-readable medium. The controller / processor 475 provides demultiplexing between transmit and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the second communication device 450. The upper layer data packets from the controller / processor 475 may be provided to the core network. The controller / processor 475 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
