Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for transmitting wireless signals in wireless communication systems supporting cellular networks. Background Technology

[0002] In LTE (Long-term Evolution) systems, traditional network-controlled mobility includes cell-level mobility and beam-level mobility. Cell-level mobility relies on RRC (Radio Resource Control) signaling, while beam-level mobility does not involve RRC signaling. Prior to 3GPP (3rd Generation Partnership Project) Release 16, beam-level mobility only addressed beam management within a single cell. The 3GPP RAN (Radio Access Network) #80 meeting decided to conduct research on L1 / L2-centric inter-cell mobility / beam management and inter-cell multiple TRPs (Transmit / Receive Points). Summary of the Invention

[0003] In discussions of L1 / L2-centric inter-cell mobility and inter-cell multiple TRPs, the network configures at least one additional cell for the UE (User Equipment), allowing the UE to utilize the better link quality of the additional cell for transmission. In this scenario, when the UE's downlink physical layer channel or signal (e.g., but not limited to CSI-RS) overlaps with the synchronization signal of the additional cell in the time domain, the question of what quasi-co-location (QCL) relationship the UE uses to receive the downlink physical layer channel or signal is a problem that needs to be addressed.

[0004] To address the aforementioned issues, this application discloses a solution. It should be noted that although the above description uses cellular networks as an example, this application is also applicable to other scenarios such as sidelink transmission, achieving similar technical effects to those in cellular networks. Furthermore, adopting a unified solution for different scenarios (including but not limited to cellular networks and sidelink transmission) helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in the first node of this application can be applied to the second node, and vice versa. Where there is no conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0005] As an example, the interpretation of the terminology in this application is based on the definition in the 3GPP specification protocol TS36 series.

[0006] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS38 series.

[0007] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS37 series.

[0008] As an example, the interpretation of terms in this application is based on the definitions in the IEEE (Institute of Electrical and Electronics Engineers) specification protocols.

[0009] This application discloses a method used in a first node of wireless communication, characterized by comprising:

[0010] A first configuration information block is received, which is used to determine the configuration information of a first reference signal. The configuration information of the first reference signal includes a first TCI state, and the first TCI state indicates a second reference signal.

[0011] The system receives the first reference signal and the first signal, wherein the configuration information of the first reference signal is used to determine the first PCI, the first signal indicates the second PCI, and the first signal includes a synchronization signal.

[0012] Wherein, the first reference signal and the first signal overlap in the time domain; the second PCI is not equal to the PCI of the target cell, and the target cell is the serving cell of the first node; whether the first reference signal and the first signal are quasi-co-located is related to whether the first PCI and the second PCI are equal; when the first PCI is equal to the second PCI, the first reference signal and the first signal are quasi-co-located.

[0013] As an example, the problem this application aims to solve includes: when the downlink physical layer signal overlaps with the synchronization signal of an additional cell in the time domain, what QCL relationship should the UE use to receive the downlink physical layer signal? The above method determines whether the downlink physical layer signal and the synchronization signal of the additional cell are quasi-co-located based on the relationship between the cell and the additional cell associated with the downlink physical layer signal through the QCL relationship, thereby solving this problem.

[0014] As an example, the features of the above method include: the first signal includes a synchronization signal of an additional cell of the first node; whether the first reference signal is associated with the same additional cell through a QCL relationship is used to determine whether the first reference signal and the first signal are quasi-co-located when they overlap in the time domain.

[0015] As an example, the advantages of the above method include: the first node can flexibly choose to prioritize receiving the reference signal of the serving cell or the synchronization signal of the supplementary cell according to its needs.

[0016] As an example, the advantages of the above method include: when the first reference signal is associated with an additional cell through the QCL relationship, the first node needs to monitor the synchronization signal in the additional cell to correctly receive the first reference signal. The above method ensures that in this case, the first node preferentially receives the synchronization signal of the additional cell.

[0017] According to one aspect of this application, when the first PCI is not equal to the second PCI, the first node determines for itself whether the first reference signal and the first signal are quasi-co-located.

[0018] According to one aspect of this application, when the first PCI is not equal to the second PCI, the first reference signal and the first signal are not allowed to co-address.

[0020] As an example, the advantages of the above method include: when a (active) TCI state or a currently used TCI state of the first node is associated with an additional cell through a QCL relationship, the first node needs to monitor the synchronization signal in the additional cell in order to accurately determine the spatial domain filter corresponding to each TCI state. The above method ensures that in this case, the first node preferentially receives the synchronization signal of the additional cell.

[0286] Example 3

[0287] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in the attached diagram. Figure 3 As shown.

[0288] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture of the control plane 300 between the first communication node device (UE, gNB, or RSU in V2X) and the second communication node device (gNB, UE, or RSU in V2X), or between two UEs, is illustrated using 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. Layer 1 will be referred to as PHY 301 in this document. Layer 2 (L2 layer) 305, above PHY 301, is responsible for the link between the first and second communication node devices, or between two UEs. Layer 2 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and supports cross-cell mobility between second communication node devices and the first communication node device. RLC sublayer 303 provides upper layer data packet segmentation and reassembly, retransmission of lost data packets, and data packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell between the first communication node devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second and first communication node devices. The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first and second communication node devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for physical layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355 and MAC sublayer 352 in L2 layer 355. However, 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, which is responsible for mapping between QoS streams and data radio bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

[0298] Example 4

[0299] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. (Attached) Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0300] The first communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0301] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0302] In the 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 L2 layer functionality. In the L2 layer, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operation, 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). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and 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-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more parallel streams. 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 domains, and subsequently uses Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. 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 multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0303] 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 radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations 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 receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any parallel stream destined for the second communication device 450. Symbols on each parallel stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted over the physical channel by the first communication device 410. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2 (L2). The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the DL (Layered Logic), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer packets from the core network. The upper-layer packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 (L3) for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0304] 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 functions at the first communication 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 communication 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 communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated parallel stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0305] 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 receiving 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 radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. 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 computer-readable media. The controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels 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 ACK and / or NACK protocols to support HARQ operation.

[0579] Example 15 illustrates a schematic diagram of whether a first reference signal and a first signal are quasi-co-located according to an embodiment of this application; as shown in the attached diagram. Figure 15 As shown. In Embodiment 15, when the first condition is met, the first reference signal and the first signal are quasi-co-located; when the first condition is not met, the first reference signal and the first signal are not allowed to co-locate.

[0580] As an example, when the first condition is met, the first node assumes that the first reference signal and the first signal are quasi-co-located; when the first condition is not met, the first node does not assume that the first reference signal and the first signal are quasi-co-located.

[0581] As an example, the first condition is satisfied when the first PCI is equal to the second PCI.

[0582] As an example, the first condition only includes the existence of a PCI in the first PCI set that is equal to the second PCI.

[0583] As an example, the first condition is satisfied when there is a PCI in the first PCI set that is equal to the second PCI; the first condition is not satisfied when no PCI in the first PCI set is equal to the second PCI.

[0584] As an example, the first TCI state set includes at least one TCI state, and the first PCI set includes at least one PCI.

[0585] As an example, the number of TCI states included in the first TCI state set is equal to the number of PCIs included in the first PCI set, and there is a one-to-one correspondence between all TCI states in the first TCI state set and all PCIs in the first PCI set; any TCI state in the first TCI state set is used to determine the corresponding PCI.

[0592] As an example, for any TCI state in the first TCI state set, if the any TCI state indicates only one reference signal resource and indicates a cell index for the only reference signal resource, the cell index is used to determine the PCI corresponding to the any TCI state.

[0593] As an example, for any TCI state in the first TCI state set, if any TCI state indicates two reference signal resources and indicates a cell index for each of the two reference signal resources, the cell index corresponding to the reference signal resource corresponding to QCL-TypeD in the two reference signal resources is used to determine the PCI corresponding to any TCI state.

[0594] As an example, for any TCI state in the first TCI state set, if any TCI state indicates two reference signal resources and does not indicate a cell index for the reference signal resource corresponding to QCL-TypeD among the two reference signal resources, the PCI corresponding to any TCI state is equal to the PCI of the target cell.

[0596] As an example, for any TCI state in the first TCI state set, if the any TCI state indicates only one SS / PBCH Block resource and indicates a cell index for the only SS / PBCH Block resource, the cell index is used to determine the PCI corresponding to the any TCI state.

[0597] As an example, for any TCI state in the first TCI state set, if the any TCI state indicates a CSI-RS resource and an SS / PBCH Block resource, and each of the CSI-RS resource and the SS / PBCH Block resource indicates a cell index, then only the cell index corresponding to the SS / PBCH Block resource is used to determine the PCI corresponding to the any TCI state.

[0598] As a sub-implementation of the above embodiment, the SS / PBCH Block resource corresponds to QCL-TypeD.

[0599] As an example, for any TCI state in the first TCI state set, if any TCI state indicates a CSI-RS resource and an SS / PBCH Block resource, and no cell index is indicated for the SS / PBCH Block resource, the PCI corresponding to any TCI state is equal to the PCI of the target cell.

[0600] As a sub-implementation of the above embodiment, the SS / PBCH Block resource corresponds to QCL-TypeD.

[0601] As an example, for any TCI state in the first TCI state set, if the one or more reference signal resources indicated by the any TCI state do not include SS / PBCH Block resources, the TCI state of the one or more reference signals indicated by the any TCI state is used to determine the PCI corresponding to the any TCI state.

[0602] As a sub-implementation of the above embodiment, the TCI state of the reference signal resource whose QCL type is QCL-TypeD among the plurality of reference signals is used to determine the PCI corresponding to any TCI state.
