Description

Technical Field

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

[0002] Multi-antenna technology is a key technology in 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system and NR (New Radio) system. Additional spatial degrees of freedom are obtained by configuring multiple antennas at communication nodes, such as base stations or UE (User Equipment). Multiple antennas use beamforming to form beams pointing in a specific direction to improve communication quality. When multiple antennas belong to multiple TRPs (Transmitter Receiver Points) / panels, additional diversity gain can be obtained by utilizing the spatial differences between different TRPs / panels. In NR R (release) 16, multi-TRP-based transmission is introduced to enhance the transmission quality of the downlink data channel.

[0003] The beams formed by multi-antenna beamforming are generally narrow, and the beams of the two communicating parties need to be aligned for effective communication. When the transmit / receive beams are out of sync due to reasons such as UE movement, the communication quality will be greatly reduced or even unable to communicate. NR R15 and R16 introduced beam management and beam failure recovery mechanisms for beam selection, update and indication between the communicating parties, and quickly restore beam synchronization when the beams of the two communicating parties are out of sync. Summary of the invention

[0004] In NR R17 and its subsequent versions, the transmission scheme based on multiple TRP / panel will continue to evolve and be enhanced. One important aspect is to enhance the physical layer control channel. At the 3GPP RAN1#103-e meeting, it was agreed to establish an association between PDCCH candidates in search space sets with different TCI (Transmission Configuration Indicator) states. The associated PDCCH candidates can repeatedly transmit a DCI, and the UE can combine and decode the associated PDCCH candidates, thereby improving the transmission reliability of the downlink strong physical layer control channel. Among them, different search space sets can correspond to different TRPs to further improve the diversity gain. In this case, when a beam failure occurs in one of the TRPs, how to reduce the performance impact on the downlink strong physical layer control channel is a problem that needs to be solved.

[0005] In response to the above problems, the present application discloses a solution. It should be noted that although the above description uses cellular network and multi-TRP / panel transmission scenarios as examples, the present application is also applicable to other scenarios such as single TRP / panel transmission, carrier aggregation (Carrier Aggregation), or Internet of Things (V2X) communication scenarios, and achieves similar technical effects in cellular network and multi-TRP / panel transmission scenarios. In addition, the use of a unified solution for different scenarios (including but not limited to cellular network multi-TRP / panel transmission, single TRP / panel transmission, carrier aggregation, cellular network and Internet of Things) also helps to reduce hardware complexity and cost. In the absence of conflict, the embodiments in the first node of the present application and the features in the embodiments can be applied to the second node, and vice versa. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other.

[0006] The present application discloses a method in a first node used for wireless communication, characterized by comprising:

[0007] Sending a first signal;

[0008] receiving a second signal;

[0009] After a first time, monitoring a first type of channel in a first set of resource particle groups;

[0010] The first signal carries a first information block, and the first signal is used to determine whether the first information block includes an index of a first type of reference signal; the second signal is later than the first signal in the time domain; the second signal is used to determine the first time, the first resource particle group set includes at least one resource particle group, and a resource particle group includes a positive integer number of resource particles greater than 1; the first resource particle group set includes at least one of the first resource particle group or the second resource particle group; the first information block is used to determine at least one of the following:

[0011] - Which resource particle group or groups of the first resource particle group and the second resource particle group are included in the first resource particle group set;

[0012] - Whether the first resource particle group and the second resource particle group are associated.

[0013] As an embodiment, the problem to be solved by the present application includes: when a beam failure occurs in a TRP corresponding to two originally associated PDCCH candidates, how to reduce the performance impact on the downlink strong physical layer control channel. In the above scheme, the UE determines whether to continue to monitor the PDCCH in the two PDCCH candidates and / or whether to maintain the association between the two PDCCH candidates based on the new beam selection of the TRP where the beam failure occurs, thereby solving this problem.

[0014] As an embodiment, the characteristics of the above method include: the first resource particle group and the second resource particle group were originally associated and corresponded to different TRPs; the first signal indicated that a beam failure occurred in one of the TRPs, and the first information block indicated the new beam selection of the TRP where the beam failure occurred; after the beam failure occurs, whether the UE continues to monitor the PDCCH in the first resource particle group and the second resource particle group and / or the first resource particle group and the second resource particle group are still associated, is related to the content of the first information block.

[0015] As an embodiment, the benefits of the above method include: when a TRP fails due to a beam failure and there is no new beam that meets the requirements and therefore cannot work normally, the UE stops monitoring the PDCCH in the PDCCH candidates corresponding to this TRP, thereby ensuring the transmission reliability of the PDCCH.

[0016] As an embodiment, the benefits of the above method include: when a TRP fails due to a beam failure and there is no new beam that meets the requirements and therefore cannot work normally, the UE terminates the combined decoding of two originally associated PDCCH candidates, thereby avoiding performance degradation caused by the combined decoding of the TRP with beam failure.

[0246] Embodiment 3 shows a schematic diagram of an embodiment of a wireless protocol architecture of a user plane and a control plane according to the present application, as shown in the attached Figure 3 shown. Figure 3is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3The radio protocol architecture of the control plane 300 between a first communication node device (UE, gNB or RSU in V2X) and a second communication node device (gNB, UE or RSU in V2X), or between two UEs is shown with 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 as PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first communication node device and the second communication node device, or between two UEs. 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 device. 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 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 the lower layer using RRC signaling between the second communication node device and the first communication node device.

[0254] Example 4

[0255] 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 the attached figure. Figure 4 Attached 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.

[0256] The first communication 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 .

[0257] 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.

[0258] In transmission from the first communication device 410 to the second communication device 450, at the first communication 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 communication 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 communication 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 streams. 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 domain and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs a transmit analog precoding / beamforming operation 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, and then provides it to a different antenna 420.

[0259] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal through 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 and provides it to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receiving analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receiving analog precoding / beamforming operation from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiving processor 456, wherein the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any parallel stream destined for the second communication device 450. The symbols on each parallel stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving 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 storing program codes and data. The memory 460 may be referred to as a computer-readable medium. In DL, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover the 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 L3 for L3 processing. The controller / processor 459 is also responsible for error detection using confirmation (ACK) and / or negative confirmation (NACK) protocols to support HARQ operations.

[0260] In the transmission from the second communication device 450 to the first communication device 410, at the second communication 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 transmission function at the first communication device 410 described in 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 communication device 410, and implements L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Then, the transmit processor 468 modulates the generated parallel stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via the transmitter 454 after analog precoding / beamforming operations in the multi-antenna transmit processor 457. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream, and then provides it to the antenna 452.

[0261] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the reception function at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna reception processor 472 and the reception processor 470. The reception processor 470 and the multi-antenna reception processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 can be associated with a memory 476 that stores program codes and data. The memory 476 can be referred to as a computer-readable medium. The controller / processor 475 provides demultiplexing between transmission and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the second communication device 450. The upper layer data packets from the controller / processor 475 can 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.
