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] Existing NR (New Radio) systems support the application of orthogonal sequences to PUCCH (Physical Uplink Control Channel) to achieve multiplexing between users.

[0003] Applying orthogonal sequences to PUSCH (Physical Uplink Shared Channel) can further improve the system's multiplexing capability, thereby significantly increasing uplink capacity. Summary of the Invention

[0004] After introducing PUSCH orthogonal sequences, optimizing the corresponding system design is a key issue that needs to be considered; this application discloses a solution to the above problem. It should be noted that this application is applicable to various wireless communication scenarios, such as non-terrestrial networks (NTN) and terrestrial networks (TN), and achieves similar technical effects. Furthermore, adopting a unified solution for different scenarios (including non-terrestrial and terrestrial networks) can help reduce hardware complexity and cost, or improve performance. Unless otherwise specified, embodiments and features in any node of this application can be applied to any other node. Unless otherwise specified, embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

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 V2X (Vehicle to Everything) RSU, on-board equipment, or on-board communication module) and the second communication node device (gNB, UE, or V2X RSU, on-board equipment, or on-board communication module), or between two UEs, is illustrated 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 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. L2305 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. 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 among 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 configuring the lower layer using RRC signaling between the second communication node device and the first communication node device.The radio protocol architecture of user plane 350 includes Layer 1 (L1) and Layer 2 (L2). 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 packets to reduce radio transmission overhead. L2 layer 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 the L2 layer 355, including a network layer (e.g., the 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., a remote UE, server, etc.).

[0164] 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.

[0165] 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-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 to generate one or more spatial streams. Transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it 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. 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 multi-antenna transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0166] 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.

[0167] 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.

[0168] 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.

[0190] The second node U2 sends the first signaling in step S521 and receives at least the first signal in step S522.

[0191] In Example 5, configuring uplink grant depends on the first signaling, and the configuration uplink grant includes the first uplink grant; whether the first uplink grant is passed to the corresponding HARQ process depends on whether there is an overlap between the first resource pool and the first type of PUSCH resources, the first resource pool depends on the configuration of the PUSCH orthogonal sequence, and the first type of PUSCH resources correspond to the uplink grant received in dynamic grant or RAR.

[0214] Example 6

[0215] Example 6 illustrates a schematic diagram illustrating the configuration of a first resource pool dependent on an orthogonal PUSCH sequence according to an embodiment of this application, as shown in the attached diagram. Figure 6 As shown.

[0221] As an example, the first resource pool is continuous in the time domain.

[0222] As an example, the first resource pool may be discontinuous in the time domain.

[0223] As an example, a transmission resource for the first transmission block is a resource allocated to the first transmission block for one transmission.

[0224] As an example, a transmission resource for the first transmission block is a time-domain resource allocated to a single transmission of the first transmission block.

[0225] As an example, a transmission resource for the first transmission block is a time-frequency resource allocated to a single transmission of the first transmission block.

[0226] As an example, a transmission resource for the first transmission block is a transmission opportunity for the first transmission block.

[0227] As an example, a transmission resource for the first transmission block is the duration of a transmission opportunity for the first transmission block.

[0229] As an example, for a transport resource of the first transport block, it is the duration of an uplink-granted PUSCH in one of the bundles configured for uplink grant.

[0230] As an example, one transmission opportunity of the first transport block is a PUSCH transmission occasion.

[0231] As an example, one transmission opportunity of the first transmission block can be used for one transmission of the first transmission block.

[0232] As one embodiment, a transmission of the first transmission block is either the initial transmission or a retransmission of the first transmission block.

[0233] As an example, the number of transmission resources in the first resource pool for the first transmission block is equal to K.

[0234] As one embodiment, the first resource pool includes only K transmission resources for the first transmission block.

[0235] As one embodiment, the first resource pool includes time-frequency resources; from the time domain perspective, the first resource pool includes time-domain resources corresponding to the K transmission resources of the first transmission block; from the frequency domain perspective, the first resource pool includes frequency-domain resources corresponding to the K transmission resources of the first transmission block.

[0236] As an example, the word "including" in "the first resource pool includes K transmission resources for the first transmission block" is from a time-domain perspective.

[0237] As an example, the first resource pool is a time-domain resource; the first resource pool includes K transmission resources for the first transport block, meaning that the first resource pool includes the time-domain resource corresponding to each of the K transmission resources for the first transport block.

[0238] As one embodiment, the first resource pool is a time-domain resource; the first resource pool includes K transmission resources for the first transport block, meaning that the first resource pool is for the duration of the K transmission resources for the first transport block.

[0239] As an example, the first resource pool is continuous in the time domain, starting with the earliest transmission resource among the K transmission resources of the first transport block and ending with the latest transmission resource among the K transmission resources of the first transport block.

[0240] As an example, each of the K transport resources in the first resource pool for the first transport block corresponds to a separate uplink grant in one of the bundles of the configured uplink grant.

[0241] As an example, the "in" in "the K transmission resources in the first resource pool for the first transmission block" is from a time domain perspective.

[0242] As an example, the K transmission resources in the first resource pool for the first transmission block respectively correspond to different uplink grants in the bundle of the configured uplink grants.

[0243] As an example, the bundle of configured uplink grants includes multiple uplink grants, such that each of the N transport resources of the first transport block corresponds to one of the multiple uplink grants.

[0244] As one embodiment, the bundle of configured uplink grants includes N uplink grants, each of which corresponds one-to-one with N transport resources for the first transport block.

[0245] As an example, the N transmission resources for the first transmission block include the K transmission resources for the first transmission block in the first resource pool.

[0246] As an example, K is equal to N, and the K transmission resources in the first resource pool for the first transmission block are for the N transmission resources of the first transmission block.

[0247] As an example, K is less than N, and the K transmission resources in the first resource pool for the first transmission block are a proper subset of the N transmission resources for the first transmission block.

[0248] As an example, N is a positive integer multiple of K; the N transmission resources for the first transmission block are divided into N / K groups, and the number of transmission resources for the first transmission block included in each of the N / K groups is equal to K; the K transmission resources for the first transmission block in the first resource pool belong to the same group in the N / K groups.

[0249] As a sub-example of the above embodiment, N is greater than K.

[0250] As a sub-example of the above embodiments, N is equal to K.

[0251] As a sub-implementation of the above embodiments, the group to which the K transmission resources for the first transmission block in the first resource pool belong can be any one of the N / K groups, and the first uplink grant is an uplink grant corresponding to one of the K transmission resources for the first transmission block in the bundle of the configured uplink grant.

[0252] As an example, the first uplink grant may be an uplink grant in one of the bundles configured for the uplink grant that corresponds to any one of the K transport resources in the first resource pool for the first transport block.

[0253] As an example, all N transmission resources of the first transmission block are configured.

[0254] As an example, the N transmission resources of the first transmission block are arranged sequentially in the time domain.

[0255] As an example, in the grouping of the N transmission resources for the first transmission block, the earliest K transmission resources are grouped into one group, the next K transmission resources are grouped into another group, and so on.

[0256] As an example, all transmission resources in the same group of the N / K groups for the first transport block correspond to the same uplink grant in the same bundle of the configured uplink grant.

[0257] As an example, the first uplink grant is an uplink grant in the first resource pool corresponding to at least one of the K transport resources of the first transport block.

[0258] As an example, for one transport resource of the first transport block to correspond to only one uplink grant in the bundle of the configured uplink grant.

[0259] As an example, the N transmission resources of the first transmission block are all granted uplink according to the configuration.

[0260] As an example, when a transmission resource of the first transport block corresponds to an uplink grant in one of the bundles of the configured uplink grant, the transmission resource of the first transport block corresponds to the configured uplink grant.

[0261] As an example, for a transmission resource of the first transport block to correspond to the configured uplink grant, it means that the transmission resource of the first transport block corresponds to an uplink grant in a bundle of the configured uplink grant.

[0262] As an example, the N transport resources of the first transport block correspond to different uplink grants in the bundle of the configured uplink grants.

[0263] As an example, when one uplink grant in the bundle of the configured uplink grant is provided for transmission in a transmission resource for the first transport block, the transmission resource for the first transport block corresponds to the uplink grant in the bundle of the configured uplink grant.

[0264] As an example, when the first node determines to perform a transmission of the first transport block in a transport resource for the first transport block, the transmission of the first transport block is generated based on the uplink grant corresponding to the transport resource for the first transport block.

[0265] As an example, a transmission resource of the first transmission block is reserved for a single transmission of the first transmission block generated according to the corresponding uplink grant.

[0266] As an example, a transmission resource for the first transmission block is configured for a single transmission of the first transmission block generated according to the corresponding uplink grant.

[0267] As an example, the K transmission resources in the first resource pool for the first transmission block do not overlap in time domain with each other.

[0268] As an example, the K transmission resources in the first resource pool for the first transmission block are located in different time slots.

[0269] As an example, in combination with the above features, the solution disclosed in this application is particularly applicable to PUSCH repetition type A and has good compatibility with existing 3GPP protocols.

[0270] As an example, from a time domain perspective, each of the K transmission resources in the first resource pool for the first transmission block includes at least one time domain symbol.

[0271] As an example, a time-domain symbol is a symbol defined in the time domain.

[0272] As an example, a time-domain symbol is an OFDM (Orthogonal Frequency Division Multiplexing) symbol.

[0273] As an example, a time-domain symbol is a symbol in a time slot.

[0274] As an example, the N transmission resources of the first transmission block are respectively in different time slots.

[0275] As an example, the N transmission resources of the first transmission block are in N consecutive time slots.

[0276] As an example, the transmission resource of the first transmission block is in a time slot, from the perspective of the time domain.

[0277] As an example, from a time domain perspective, each of the N transport resources in the first transport block includes at least one time domain symbol.

[0278] As an example, a transmission resource is configured for the first transmission block.

[0279] As an example, a transmission resource for the first transmission block is determined according to the indication of the DCI (Downlink Control Information) format.

[0281] As an example, K equals 2.

[0282] As an example, K is equal to 2 or 4.

[0283] As an example, K is equal to one of 2, 4, or 8.

[0285] As an example, K is no greater than 1024.

[0286] As an example, K is configured.

[0287] As an example, N is configured.

[0288] As an example, N is configured by RRC layer parameters.

[0289] As an example, N is indicated by physical layer signaling.

[0290] As an example, N is equal to the number of repetitions of the configured first transport block.

[0291] As an example, N is equal to a positive integer multiple of K.

[0292] As an example, N equals 2 and K equals 2.

[0293] As an example, N equals 4 and K equals 2.

[0294] As an example, N equals 8 and K equals 2.

[0295] As an example, N equals 8 and K equals 4.

[0296] As one embodiment, a transmission of the first transmission block is either an initial transmission or a retransmission.

[0297] As an example, the initial transmission of the first transport block is the first transmission in the bundle granted by the configuration uplink.

[0298] As an example, in the bundle granted by the uplink configuration, a retransmission is triggered without waiting for feedback from the previous transmission.

[0299] As an example, the first uplink grant is for a retransmission of the first transport block.

[0300] As an example, one transmission of the first transport block is a transmission on the PUSCH.

[0301] Example 7

[0302] Example 7 illustrates a schematic diagram of a first resource pool according to an embodiment of this application, as shown in the attached diagram. Figure 7 As shown. In the appendix Figure 7 In the diagram, a gray-filled box represents a transport resource for the first transport block.

[0303] In embodiment 7, K equals 2 (the length of the PUSCH orthogonal sequence is 2); the first resource pool consists of time-domain resources corresponding to the two transmission resources of the first transport block (these two transmission resources are continuous in the time domain).

[0304] As an example, the first resource pool is a time-domain resource.

[0305] As an example, both the first resource pool and a transmission resource for the first transport block are time-domain resources.

[0306] As an example, for a transmission resource of the first transmission block to be a time-domain resource, the time-domain resource corresponding to the transmission resource of the first transmission block refers to the transmission resource itself.

[0307] As an example, a transmission resource for the first transmission block also includes definitions in other dimensions (e.g., frequency domain) besides the time domain.

[0308] Example 8

[0309] Example 8 illustrates a schematic diagram of a first resource pool according to an embodiment of this application, as shown in the attached diagram. Figure 8 As shown. In the appendix Figure 8In the diagram, a gray-filled box represents a transport resource for the first transport block.
