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 5G NR systems, in order to support wireless communication on high-frequency bands (e.g., the band between 52.6 GHz and 71 GHz), 3GPP considered supporting a scheduling method in NR Release 17 that allows one DCI (Downlink Control Information) signaling to schedule multiple PDSCH (Physical Downlink Shared Channel) receptions. Summary of the Invention

[0003] After introducing the function of scheduling multiple PDSCH receptions with a single DCI, how to reasonably adjust the usage of DAI (Downlink Assignment Index) to determine the HARQ-ACK (Hybrid Automatic Repeat Request ACK) codebook is a key issue that must be solved.

[0004] To address the aforementioned problems, this application discloses a solution. In the above description, a scenario where one DCI schedules multiple PDSCHs is used as an example; this application is also applicable to communication on different frequency bands, IoT (Internet of Things), MBS (Multicast and Broadcast Services), vehicle-to-everything (V2X), NTN (non-terrestrial networks), URLLC (Ultra-Reliable and Low-Latency Communication), XR (Extended Reality), and other transmission scenarios, achieving similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to scenarios where one DCI schedules multiple PDSCHs, communication on different frequency bands, IoT, MBS, V2X, NTN, URLLC, and XR) helps reduce hardware complexity and cost. It should be noted that, unless otherwise specified, the embodiments and features in the user equipment of this application can be applied to the base station, and vice versa.

The 5G NR or LTE network architecture 200 may be referred to as EPS (Evolved Packet System) 200 or some other suitable term. EPS 200 may include one or more UE (User Equipment) 201, NG-RAN (Next Generation Radio Access Network) 202, EPC (Evolved Packet Core) / 5G-CN (5G-Core Network) 210, HSS (Home Subscriber Server) 220, and Internet service 230. EPS may interconnect with other access networks, but these entities / interfaces are not shown for simplicity. As shown in the diagram, EPS provides packet-switched services; however, those skilled in the art will readily understand that the various concepts presented throughout this application can be extended to networks providing circuit-switched services or other cellular networks. NG-RAN includes NR Node B (gNB) 203 and other gNBs 204. gNB 203 provides user and control plane protocol termination to UE 201. gNB 203 can connect to other gNBs 204 via the Xn interface (e.g., backhaul). gNB 203 may also be referred to as a base station, base transceiver station, radio base station, radio transceiver, transceiver function, Basic Service Set (BSS), Extended Service Set (ESS), TRP (Transmitter Receiver Node), or some other suitable term. gNB 203 provides UE 201 with access to EPC / 5G-CN 210. Examples of UE201 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, non-terrestrial base station communications, satellite mobile communications, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, drones, aircraft, narrowband IoT devices, machine-type communication devices, land vehicles, automobiles, wearable devices, or any other similar functional devices. Those skilled in the art may also refer to UE201 as a mobile station, subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or any other suitable term. gNB203 connects to EPC / 5G-CN 210 via the S1 / NG interface.The EPC / 5G-CN 210 includes the MME (Mobility Management Entity), AMF (Authentication Management Field), and UPF (User Plane Function) 211, other MMEs, AMFs, and UPFs 214, the S-GW (Service Gateway) 212, and the P-GW (Packet Data Network Gateway) 213. The MME / AMF / UPF 211 is the control node that handles signaling between the UE 201 and the EPC / 5G-CN 210. Generally, the MME / AMF / UPF 211 provides bearer and connection management. All user IP (Internet Protocol) packets are transmitted through the S-GW 212, which is itself connected to the P-GW 213. The P-GW 213 provides UE IP address allocation and other functions.

[0372] Example 3

[0373] 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 for 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. L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second communication node devices and between the two UEs via PHY301. 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. 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.

[0386] Example 4

[0387] Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in the access network.

[0388] 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.

[0389] 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.

[0390] 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 transmission from the first communication device 410 to the second communication 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 second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting 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 mapping of signal clusters 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 spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it 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.

[0391] 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 spatial stream destined for the second communication device 450. Symbols on each spatial 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 the functions of Layer 2. 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 transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0392] 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 transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting 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 spatial 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.

[0393] 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. In the transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.

[0515] Example 9

[0516] Example 9 illustrates a schematic diagram of the relationship between the number of transport blocks carried by a transport block-based PDSCH reception associated with a first time unit scheduled by a first type of DCI according to an embodiment of this application and K, as shown in the attached diagram. Figure 9 As shown.

[0517] In Example 9, the number of transport blocks carried by the transport block-based PDSCH receivers associated with the first time unit scheduled by the first type of DCI is greater than K.

[0518] As an example, for a first type of DCI: all transport blocks carried by the scheduled transport block-based PDSCH reception are associated with a first time unit; or, a portion of the transport blocks carried by the scheduled transport block-based PDSCH reception are associated with a first time unit, and another portion of the transport blocks carried by the scheduled transport block-based PDSCH reception are associated with a time unit other than the first time unit.

[0519] As an example, the first signal is transmitted in the first time unit.

[0520] As an example, a first type of DCI is a DCI that satisfies either {all transport blocks carried by the scheduled transport block-based PDSCH reception are associated with a first time unit; or, a portion of the transport blocks carried by the scheduled transport block-based PDSCH reception are associated with a first time unit, and another portion of the transport blocks carried by the scheduled transport block-based PDSCH reception are associated with a time unit other than the first time unit}.

[0521] As one embodiment, a portion of the transport blocks carried by the transport block-based PDSCH reception scheduled by the first DCI are associated with a first time unit, and another portion of the transport blocks carried by the transport block-based PDSCH reception scheduled by the first DCI are associated with another time unit outside the first time unit.

[0522] As an example, when a DCI is used to schedule transport block-based PDSCH reception, and a portion of the transport blocks carried by the transport block-based PDSCH reception scheduled by the DCI are associated with a first time unit, and another portion of the transport blocks carried by the transport block-based PDSCH reception scheduled by the DCI are associated with another time unit outside the first time unit, and the number of transport blocks carried by the transport block-based PDSCH reception scheduled by the DCI and associated with the first time unit is greater than K: the DCI is a DCI of the first type.

[0523] As an example, when a DCI is used to schedule transport block-based PDSCH reception, and all transport blocks carried by the transport block-based PDSCH reception scheduled by the DCI are associated with a first time unit, and the number of transport blocks carried by the transport block-based PDSCH reception scheduled by the DCI and associated with the first time unit is greater than K: the DCI is a DCI of the first type.

[0524] As an example, the first DCI is a first type of DCI; the total number of transport blocks carried by the transport block-based PDSCH reception scheduled by the first DCI is greater than N, where N is a higher-layer signaling configuration or predefined value.

[0525] As an example, when the total number of transport blocks carried by a transport block-based PDSCH reception scheduled by a DCI is greater than N: the DCI indicates that different HARQ-ACK information is fed back in multiple different time units.

[0526] As an example, when the total number of transport blocks carried by a transport block-based PDSCH reception scheduled by a DCI is not greater than N: the DCI instructs to feed back HARQ-ACK information for all transport blocks carried by the transport block-based PDSCH reception scheduled by the DCI in the same time unit.

[0527] As an example, the first DCI is a first-class DCI, and the number of transport blocks carried by the transport block-based PDSCH receptions associated with the first time unit scheduled by the first DCI is greater than K.

[0528] As an example, the first DCI is a first type of DCI; the total number of transport block-based PDSCH receptions scheduled by the first DCI is greater than N, where N is a higher-layer signaling configuration or predefined value.

[0529] As an example, when the total number of PDSCH receptions scheduled by a DCI is greater than N: the DCI indicates that it should feed back different HARQ-ACK information in multiple different time units.

[0530] As an example, when the total number of PDSCH receptions scheduled by a DCI is not greater than N: the DCI indicates that it should feed back all HARQ-ACK information for all PDSCH receptions scheduled by the DCI in the same time unit.

[0531] As an example, both the first type of DCI and the second type of DCI indicate the first time unit.

[0532] As an example, a DCI that does not indicate the first time unit belongs to neither the first type of DCI nor the second type of DCI.

[0533] As an example, when a DCI is not used to schedule transport block-based PDSCH reception: the DCI does not belong to the first type of DCI.

[0534] As an example, when any transport block carried by a transport block-based PDSCH reception scheduled by a DCI is not associated with a first time unit: the DCI does not belong to the first type of DCI.

[0535] As an example, when the number of transport blocks carried by a transport block-based PDSCH reception associated with a first time unit scheduled by a DCI is not greater than K: the DCI does not belong to the first type of DCI.

[0536] As an example, the second type of DCI is used to schedule the reception of PDSCH based on code block groups associated with the first time unit.

[0537] As an example, in this application, the association of a transport block with a time unit means that the HARQ-ACK information bits generated for the transport block are transmitted in the time unit.

[0538] As an example, in this application, the association of a transport block with a time unit means that a PUCCH in the time unit is used to carry HARQ-ACK information bits generated for the transport block.

[0539] As an example, in this application, the association of a transport block with a time unit means that the HARQ-ACK information bits generated for the transport block by the DCI instruction scheduling the transport block are transmitted in the time unit.

[0540] As an example, in this application, the association of a PDSCH reception with a time unit means that the HARQ-ACK information bits generated for the PDSCH reception are transmitted in the time unit.

[0541] As an example, in this application, the association of a PDSCH reception with a time unit means that a PUCCH in the time unit is used to carry HARQ-ACK information bits generated for the PDSCH reception.

[0542] As an example, in this application, the association of a PDSCH reception with a time unit means that the DCI indicating the scheduling of the PDSCH reception is that the HARQ-ACK information bits generated for the PDSCH reception are transmitted in the time unit.

[0543] As an example, a transport block carried by a transport block-based PDSCH reception associated with the first time unit is associated with the first time unit; and the transport block carried by the transport block-based PDSCH reception associated with the first time unit is carried by the transport block-based PDSCH reception.

Without conflict, features in the various sub-embodiments of Embodiment 10 can be arbitrarily combined with each other.

[0546] In Embodiment 10, the first node in this application further receives at least one third type DCI; wherein, the time domain resources occupied by one of the third type DCIs belong to a time interval preceding the time interval to which the time domain resources occupied by the first DCI in this application belong; the third type DCI indicates the first time unit in this application; the third type DCI is used to schedule transport block-based PDSCH reception, and the number of transport blocks carried by the transport block-based PDSCH reception scheduled by the third type DCI is no greater than K; the value of the first field in this application included in the first DCI is unrelated to the third type DCI.

[0547] As a sub-implementation of Embodiment 10, from a time domain perspective, the first resource pool includes the time interval to which the time domain resource occupied by the third type of DCI received by the first node belongs.

[0548] As a sub-implementation of Embodiment 10, the value of the first field in this application included in the first DCI is independent of the number of the third type of DCI received by the first node.

[0549] As an example, one of the third type of DCI is a DCI format 1_0, and the specific definition of the DCI format 1_0 can be found in section 7.3.1.2 of 3GPP TS38.212.

[0550] As an example, one of the third type of DCI is a DCI format 1_1, and the specific definition of the DCI format 1_1 can be found in section 7.3.1.2 of 3GPP TS38.212.

[0555] In Embodiment 11, the first node in this application receives a DCI; the DCI indicates a first time unit, and the total number of transport blocks carried by the transport block-based PDSCH reception scheduled by the DCI is greater than K1; the number of transport blocks carried by the transport block-based PDSCH reception scheduled by the DCI and associated with the first time unit is related to the total number of transport blocks carried by the transport block-based PDSCH reception scheduled by the DCI.

[0556] As a sub-example of Example 11, the DCI also indicates another time unit.

[0557] As a sub-example of Example 11, the number of transport blocks carried by the PDSCH reception based on transport blocks and associated with the first time unit scheduled by the DCI is equal to the result of dividing the total number of transport blocks carried by the PDSCH reception based on transport blocks scheduled by the DCI by 2 by rounding up or down.

[0558] As a sub-implementation of Embodiment 11, a DCI belongs to the first type of DCI in this application only if the number of transport blocks carried by the PDSCH reception based on transport blocks associated with the first time unit scheduled by the DCI is greater than K in this application.

[0559] As a sub-example of Embodiment 11, the DCI is the first DCI in this application.

[0560] As a sub-example of Embodiment 11, the DCI is another DCI other than the first DCI in this application.

[0561] As an example, when a DCI does not indicate a first time unit or the total number of transport blocks carried by the transport block-based PDSCH reception scheduled by the DCI is not greater than K1, the DCI does not belong to the first type of DCI in this application.

[0565] As an example, K1 is equal to 1.

[0566] As an example, K1 equals 2.
