Description

A method and apparatus for multi-cell scheduling in nodes used in wireless communication

[0001] This application claims priority to Chinese Patent Application No. 202411434408.X, filed on October 14, 2024, entitled "A Method and Apparatus for Multi-Cell Scheduling in a Node for Wireless Communication", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to signal transmission methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for multi-cell scheduling. Background Technology

[0003] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. In order to meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #105 plenary meeting decided to enhance multi-carrier technology in New Radio (NR) (or 5G) Phase 2. One important enhancement is to enable multiple cells that are simultaneously scheduled to support different SCS (Subcarrier Spacing) / carrier types.

[0004] In existing NR systems, Release 18 already supports multiple different carriers being scheduled by the same DCI (Downlink Control Information) to improve transmission bandwidth and efficiency. However, in Release 18, multiple co-scheduled cells need to maintain the same SCS (Search Channel Classification). The new WID (Work Item Description) "Multi-carrier Enhancement for NR Phase 2," agreed upon at RAN#105 for Release 19, builds upon Release 18 to achieve more flexible single-DCI multi-cell scheduling. Summary of the Invention

[0005] In multi-carrier communication processes, such as carrier aggregation (CA), the system supports cross-carrier scheduling. In networks supported by existing standards, such as Rel-18 and earlier versions of 5G NR, for multiple scheduled cells, it is necessary to ensure that the subcarrier spacing of multiple cells is the same. In the relevant discussions of Rel-19, the above-mentioned restriction that multiple cells need to have the same subcarrier spacing will not exist, thereby improving the system's flexibility.

[0006] To address the problem of simultaneously scheduling multiple cells with different subcarrier spacings using the same PDCCH in NR multi-cell scheduling scenarios, this application discloses a solution. It should be noted that although this application is initially intended for multi-cell scheduling scenarios, it can also be applied to other non-multi-cell scheduling scenarios. Furthermore, adopting a unified design scheme for different scenarios (such as other non-multi-cell scheduling scenarios, including but not limited to capacity enhancement systems, short-range communication systems, unlicensed spectrum communication, IoT (Internet of Things), URLLC (Ultra-Reliable Low Latency Communication) networks, and vehicle-to-everything (V2X) networks) helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in any node of this application can be applied to any other node. Where there is no conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

Where necessary, reference can be made to TS38.211, TS38.212, TS38.213, TS38.214, TS38.215, TS38.300, TS38.304, TS38.305, TS38.321, TS38.331, TS37.355, and TS38.423 in the 3GPP technical specifications to aid in understanding this application.

[0013] As an example, the interpretation of the terms used in this application is based on the definitions in 3GPP specification protocol Rel-18.

[0014] This application discloses a method for a first node used in multi-cell scheduling for wireless communication, comprising:

[0015] Receive the first information block and the second information block;

[0016] The first receiver receives a first DCI (Downlink Control Information), which schedules a first set of cells, which includes multiple cells.

[0017] The first DCI includes a first domain, and the interpretation of the first domain of the first DCI depends on the target information block, which is either the first information block or the second information block. Whether the target information block is the first information block or the second information block depends on whether the subcarrier spacing used by the active BWP (BandWidth Part) corresponding to all cells included in the first cell set is the same.

[0018] As an example, the problem to be solved by this application includes: the interpretation of the corresponding domains in the DCI when multiple scheduled cells, i.e., cells in the first cell set, use different subcarrier intervals.

[0019] As an example, the features of this application include: when multiple scheduled cells share the first domain in a DCI, the interpretation of the first domain depends on whether the cells in the first cell set use the same subcarrier spacing; and thus, the interpretation of the first domain is different for the two scenarios of using the same subcarrier spacing and using different subcarrier spacing.

[0020] As an example, the features of this application include: for scenarios where cells in the first cell set use different subcarrier intervals, adding new higher-layer parameters, namely the second information block, to adapt to the scheduling requirements corresponding to different subcarrier intervals, thereby further increasing flexibility and improving the overall system performance.

[0021] According to one aspect of this application, the above method is characterized in that, when the active BWPs corresponding to all cells included in the first cell set adopt the same subcarrier spacing, the target information block is the first information block; when the active BWPs corresponding to all cells included in the first cell set do not adopt the same subcarrier spacing, the target information block is the second information block.

[0022] As an example, the features of this application include: for the first set of cells to be scheduled, different parameter sets are designed for two scenarios, namely the first information block and the second information block, respectively, to adapt to the scheduling requirements corresponding to different subcarrier intervals, thereby further increasing flexibility and improving the overall system performance.

[0023] According to one aspect of this application, the above method is characterized in that the first DCI is a downlink grant, the first field included in the first DCI indicates the time domain location of HARQ-ACK (Hybrid Automatic Repeat request Acknowledgement) for a channel in at least one cell included in the first cell set, and the target information block includes a timing list of PDSCH (Physical Downlink Shared Channel) to downlink ACK (Acknowledgement) configured by RRC (Radio Resource Control) signaling.

[0024] As an example, the features of this application include: when the first field indicates the HARQ-ACK feedback time, because the subcarrier intervals of the cells in the first set of scheduled cells are different, the corresponding processing delays will also be different; while in the traditional single DCI scheduling multi-cell scenario in Release-17, the subcarrier intervals of multiple cells are the same, and the above problem will not occur; therefore, a new timing list needs to be designed to meet the different delay requirements caused by different cells using different subcarrier intervals.

[0025] According to one aspect of this application, the above method is characterized in that the first DCI is a downlink grant, the first field included in the first DCI indicates the PRB bundling size of the channel in at least one cell included in the first cell set, and the target information block includes the PRB (Physical Resource Block) bundling type configured by RRC signaling.

[0026] As an example, the features of this application include: when the first field indicates the PRB bundling size, because the subcarrier spacings of the cells in the first set of scheduled cells are different, the corresponding PRB bundling size and channel decoding methods will also be different; while in the traditional single DCI scheduling multi-cell scenario in Release-17, the subcarrier spacings of multiple cells are the same, and the above-mentioned problem will not occur; therefore, a new timing list needs to be designed to meet the different delay requirements caused by different cells using different subcarrier spacings.

[0027] According to one aspect of this application, the above method is characterized in that the first DCI is an uplink grant, the first field included in the first DCI indicates the beta_offset of the codebook for HARQ-ACK for at least one channel in the first cell set, and the target information block includes BetaOffsets of RRC signaling configuration.

[0028] As an example, the features of this application include: when the first field indicates the beta_offset used by the codebook of HARQ-ACK, because the subcarrier intervals of the cells in the first set of scheduled cells are different, the appropriate beta_offset values ​​will also be different; while in the traditional single DCI scheduling multi-cell scenario in Release-17, the subcarrier intervals of multiple cells are the same, and the above problem will not occur; therefore, a new timing list needs to be designed to meet the different delay requirements caused by different cells using different subcarrier intervals.

[0029] According to one aspect of this application, the method is characterized in that the first field included in the first DCI indicates the frequency hopping of a channel in at least one cell included in the first cell set, and the target information block includes frequency hopping parameters configured by RRC signaling.

[0030] As an example, the features of this application include: when the first field indicates the frequency hopping parameter, because the subcarrier intervals of the cells in the first set of cells being scheduled are different, the appropriate frequency hopping parameters will also be different; while in the traditional single DCI scheduling multi-cell scenario in Release-17, the subcarrier intervals of multiple cells are the same, and the above problem will not occur; therefore, a new timing list needs to be designed to meet the requirement that different cells use different frequency hopping parameters.

[0031] According to one aspect of this application, the above method is characterized by comprising:

[0032] The channel is received in at least one cell included in the first set of cells.

In the scenario of introducing the first information block and the second information block, the interpretation method of the first field can be increased, so as to adapt to the scenario where the first cell set of scheduling adopts different subcarrier intervals, thereby improving the system's adaptability to different scenarios and improving overall performance.

[0180] Example 3

[0181] 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 Figure 3.

[0182] Figure 3 is a schematic diagram illustrating an embodiment of the wireless protocol architecture for the user plane 350 and the control plane 300. Figure 3 shows the wireless protocol architecture for the control plane 300 between a first communication node device (UE or RSU in V2X, onboard equipment or onboard communication module) and a second node device (gNB, RSU in UE or V2X, onboard equipment or onboard communication module), or between two UEs, using three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical layer) signal processing functions. L1 will be referred to herein as PHY 301. L2 305 is above PHY 301 and is responsible for the link between the first node device and the second node device, or between two UEs, through PHY 301. L2 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 node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and supports cross-cell mobility between the second communication node devices and the first communication node device. The RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat reQuest). The MAC sublayer 302 provides multiplexing between logical and transport channels. It is also responsible for allocating various radio resources (e.g., resource blocks) within 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 L3 of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and using RRC signaling between the second communication node device and the first communication node device to configure the lower layer.The wireless protocol architecture of user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The wireless 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 355, RLC sublayer 353 in L2 355, and MAC sublayer 352 in L2 355. However, PDCP sublayer 354 also provides header compression for upper-layer packets to reduce wireless transmission overhead. L2 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS (Quality of Service) streams and Data Radio Bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above L2 355, including a network layer (e.g., IP (Internet Protocol) layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.).

[0192] Example 4

[0193] 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 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.

[0194] 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.

[0195] 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.

[0196] 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 functionality. In the DL, 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 L1 (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 mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-PSK, and M-Quadrature Amplitude Modulation (M-QAM)). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, generating 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 and / or frequency domains, 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 multicarrier symbol stream provided by the multi-antenna transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0197] 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 L1 signal processing functions. 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 by the first communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements L2 functionality. 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, 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 L2. Various control signals may also be provided to L3 for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0198] 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 L2. 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 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.

[0199] 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 function. The controller / processor 475 implements the L2 function. The controller / processor 475 may be associated with a memory 476 storing 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.
