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 the 3GPP (3rd Generation Partner Project) NR (New Radio) system, in order to support URLLC (Ultra-Reliable and Low Latency Communication) services with higher requirements (such as higher reliability and lower latency), the NRR Release 16 protocol has supported a variety of uplink transmission modes based on repetition transmission, including the PUSCH repetition type B transmission mode.

[0003] The 3GPP RAN plenary meeting approved the URLLC-enhanced WI (Work Item) of NR Release 17. Among them, the enhancement of HARQ-ACK (Hybrid Automatic Repeat Request ACK) feedback for UE (User Equipment) is a key area that needs to be studied. Summary of the Invention

[0004] At its RAN1#104 meeting, 3GPP supported the introduction of delayed feedback for HARQ-ACK in SPS PDSCH; how to ensure the timing requirements between PDSCH and HARQ-ACK corresponding to the same HARQ process is a key issue that must be solved.

[0005] To address the aforementioned problems, this application discloses a solution. The problem description above uses HARQ-ACK feedback in the uplink as an example; this application is also applicable to downlink and sidelink transmission scenarios, achieving similar technical effects. Furthermore, using a unified solution for different scenarios (including but not limited to uplink, downlink, and sidelink) helps reduce hardware complexity and cost.

[0173] Example 3

[0174] 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. 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.).

[0190] Example 4

[0191] 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 an access network.

[0192] 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.

[0193] 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.

[0194] 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.

[0195] 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.

[0196] 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.

[0197] 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.

[0221] Example 5

[0222] Example 5 illustrates a signal transmission flowchart according to an embodiment of this application, as shown in the attached diagram. Figure 5 As shown. In the appendix Figure 5 In this context, the first node U1 and the second node U2 communicate via an air interface. (See attached...) Figure 5 In the dashed box F1, the step is optional; a HARQ-ACK bit block associated with the second air interface resource pool in dashed box F2 may or may not be sent. Without conflict, features in the various sub-embodiments of Embodiment 5 can be arbitrarily combined with each other.

[0223] First node U1 receives first signaling in step S5101; receives first signal in first air interface resource pool in step S511; in step S512: sends second signal in target air interface resource pool; sends a HARQ-ACK bit block associated with second air interface resource pool, or abandons sending HARQ-ACK bit block associated with second air interface resource pool.

[0225] In embodiment 5, the second signal carries a first HARQ-ACK bit block; the first HARQ-ACK bit block is associated with the first signal; from a time domain perspective, the second air interface resource pool follows the first air interface resource pool; both the first and second air interface resource pools are associated with a first HARQ process number, and the first HARQ-ACK bit block includes HARQ-ACK information bits for the first HARQ process number; whether the first transmitter sends a HARQ-ACK bit block associated with the second air interface resource pool depends on the time relationship between the target air interface resource pool and the first time point, where the first time point is associated with the second air interface resource pool; when the target air interface resource pool... When the deadline of the source pool in the time domain is earlier than the first time, the first node U1 sends a HARQ-ACK bit block associated with the second air interface resource pool; when the deadline of the target air interface resource pool in the time domain is not earlier than the first time, the first node U1 abandons sending the HARQ-ACK bit block associated with the second air interface resource pool; any two of the first air interface resource pool, the second air interface resource pool, and the target air interface resource pool do not overlap in the time domain; the first time is not later than the start time of the second air interface resource pool in the time domain; the first signaling is used to activate the first semi-persistent scheduling, and the first signaling indicates at least the former of the first air interface resource pool or the second air interface resource pool.

[0226] As a sub-implementation of Embodiment 5, the sentence "The first air interface resource pool and the second air interface resource pool are both associated with the first HARQ process number" means that: the first HARQ process number is the HARQ process number associated with the first air interface resource pool, and the HARQ process number associated with the second air interface resource pool is the same as the first HARQ process number.

[0241] As an example, Appendix Figure 5 The step in the dashed box F1 does not exist.

[0242] Example 6

[0243] Example 6 illustrates a flowchart of a first node determining whether to send a HARQ-ACK bit block associated with a second air interface resource pool according to an embodiment of this application, as shown in the attached diagram. Figure 6 As shown.

[0244] In Embodiment 6, the first node in this application determines in step S61 whether the cutoff time of the target air interface resource pool in the time domain is earlier than the first time; if so, it proceeds to step S62 to determine to send a HARQ-ACK bit block associated with the second air interface resource pool; otherwise, it proceeds to step S63 to determine to abandon sending the HARQ-ACK bit block associated with the second air interface resource pool.

[0245] As an example, when the first node / first transmitter abandons sending the HARQ-ACK bit block associated with the second air interface resource pool: the first node abandons generating the HARQ-ACK bit block associated with the second air interface resource pool.

[0246] As an example, when the cutoff time of the target air interface resource pool in the time domain is earlier than the first time: the first node performs signal reception in the second air interface resource pool.

[0247] As an example, the phrase "abandon sending HARQ-ACK bit blocks associated with the second air interface resource pool" means: abandon sending HARQ-ACK information bits associated with the second air interface resource pool.

[0248] As an example, the phrase "abandon sending HARQ-ACK bit blocks associated with the second air interface resource pool" means: not sending any HARQ-ACK bit blocks associated with the second air interface resource pool.

[0249] As an example, the phrase "abandon sending HARQ-ACK bit blocks associated with the second air interface resource pool" means: abandoning the sending of HARQ-ACK bit blocks that include HARQ-ACK information bits for one SPS PDSCH in the second air interface resource pool.

[0250] As an example, when the deadline of the target air interface resource pool in the time domain is not earlier than the first time, the first node sends a HARQ-ACK bit block associated with the second air interface resource pool; when the deadline of the target air interface resource pool in the time domain is earlier than the first time, the first node abandons sending the HARQ-ACK bit block associated with the second air interface resource pool.

[0251] As an example, when the deadline of the target air interface resource pool in the time domain is not later than the first time, the first node sends a HARQ-ACK bit block associated with the second air interface resource pool; when the deadline of the target air interface resource pool in the time domain is later than the first time, the first node abandons sending the HARQ-ACK bit block associated with the second air interface resource pool.

[0252] As an example, when the deadline of the target air interface resource pool in the time domain is later than the first time, the first node sends a HARQ-ACK bit block associated with the second air interface resource pool; when the deadline of the target air interface resource pool in the time domain is not later than the first time, the first node abandons sending the HARQ-ACK bit block associated with the second air interface resource pool.

[0253] As an example, when the start time of the target air interface resource pool in the time domain is earlier than the first time, the first node sends a HARQ-ACK bit block associated with the second air interface resource pool; when the start time of the target air interface resource pool in the time domain is not earlier than the first time, the first node abandons sending the HARQ-ACK bit block associated with the second air interface resource pool.

[0254] As an example, when the start time of the target air interface resource pool in the time domain is not earlier than the first time, the first node sends a HARQ-ACK bit block associated with the second air interface resource pool; when the start time of the target air interface resource pool in the time domain is earlier than the first time, the first node abandons sending the HARQ-ACK bit block associated with the second air interface resource pool.

[0256] As an example, when the start time of the target air interface resource pool in the time domain is later than the first time, the first node sends a HARQ-ACK bit block associated with the second air interface resource pool; when the start time of the target air interface resource pool in the time domain is not later than the first time, the first node abandons sending the HARQ-ACK bit block associated with the second air interface resource pool.

[0259] In Example 7, the first moment is associated with the second air interface resource pool.

[0260] As an example, the second air interface resource pool is used to determine the first moment.

[0261] As an example, the time-domain resources occupied by the second air interface resource pool are used to determine the first time.

[0262] As an example, the first moment is no later than the start time of the second air interface resource pool in the time domain.

[0263] As an example, the first moment is the start moment of the second air interface resource pool in the time domain.

[0264] As an example, the first moment is earlier than the start time of the second air interface resource pool in the time domain.

[0265] As an example, the first time is earlier than the start time of the second air interface resource pool in the time domain, and the time interval between the first time and the start time of the second air interface resource pool in the time domain is equal to the time domain resources occupied by K multi-carrier symbols, where K is a positive integer.

[0266] As a sub-implementation of the above embodiments, K is predefined.

[0273] In Example 8, both the first air interface resource pool and the second air interface resource pool are associated with the first HARQ process number.

[0274] As an example, the fact that both the first air interface resource pool and the second air interface resource pool are associated with the first HARQ process number means that the first HARQ process number is the HARQ process number associated with the first air interface resource pool, and the HARQ process number associated with the second air interface resource pool is the same as the first HARQ process number.

[0275] As an example, one of the HARQ process numbers in this application is equal to one of 0 to 15.

[0276] As an example, one of the HARQ process numbers in this application is equal to one of 1 to 16.

[0277] As an example, the fact that the first air interface resource pool and the second air interface resource pool are both associated with the same HARQ process number means that the first air interface resource pool and the second air interface resource pool are both associated with the same HARQ process.

[0278] As an example, the first air interface resource pool is reserved for one SPS PDSCH, and the HARQ process number associated with the first air interface resource pool is the HARQ process number corresponding to the one SPS PDSCH; the second air interface resource pool is reserved for another SPS PDSCH, and the HARQ process number associated with the second air interface resource pool is the HARQ process number corresponding to the other SPS PDSCH.

[0282] As an example, the HARQ process number associated with the first air interface resource pool is equal to: the result of taking the first intermediate quantity modulo the first HARQ process number, plus the first offset value. The first intermediate quantity is equal to the first value multiplied by 10, divided by the first time slot number, and divided by the first period value.

[0283] As an example, the first value is equal to: the system frame number (SFN) of the time domain resources occupied by the first air interface resource pool multiplied by the first time slot number plus the time slot number of the time domain resources occupied by the first air interface resource pool in the frame to which the time domain resources occupied by the first air interface resource pool belong.

[0284] As an example, the number of the first time slots is equal to the number of consecutive time slots included in each frame.

[0285] As an example, the number of the first time slots is represented by numberOfSlotsPerFrame.

[0286] As an example, the first period value is equal to the period of downlink allocation configured for the first semi-persistent scheduling in this application.

[0287] As an example, the first period value is represented by periodicity.

[0288] As an example, the number of the first HARQ processes is equal to the number of HARQ processes configured for the first semi-persistent scheduling in this application.

[0289] As an example, the number of the first HARQ processes is represented by nrofHARQ-Processes.

[0290] As an example, the first offset value is equal to the offset value of the HARQ process configured for the first semi-persistent scheduling in this application.

[0291] As an example, the first offset value is represented by harq-ProcID-Offset.

[0292] As an example, the HARQ process number associated with the second air interface resource pool is equal to: the result of taking the second intermediate quantity modulo the second HARQ process number after rounding the second intermediate quantity, where the second intermediate quantity is equal to the second value multiplied by 10 divided by the second time slot number divided by the second period value.

[0293] As an example, the HARQ process number associated with the second air interface resource pool is equal to: the result of taking the second intermediate quantity modulo the second HARQ process number, plus the second offset value. The second intermediate quantity is equal to the second value multiplied by 10, divided by the second time slot number, and divided by the second period value.

[0294] As an example, the second value is equal to: the system frame number (SFN) of the system frame to which the time domain resources occupied by the second air interface resource pool belong, multiplied by the second number of time slots, plus the time slot number of the time slot to which the time domain resources occupied by the second air interface resource pool belong in the frame to which the time domain resources occupied by the second air interface resource pool belong.

[0295] As an example, the second number of time slots is equal to the number of consecutive time slots included in each frame.

[0296] As one embodiment, the number of second time slots is: the number of first time slots.

[0297] As an example, the second period value is equal to the period allocated for the downlink configured for a semi-persistent scheduling.

[0298] As an example, the second period value is the first period value.

[0299] As an example, the number of the second HARQ processes is equal to the number of HARQ processes configured for a semi-persistent schedule.

[0300] As an example, the number of the second HARQ processes is equal to the number of the first HARQ processes.

[0301] As an example, the second offset value is equal to the offset value configured for a HARQ process in a semi-persistent scheduling.

[0314] As an example, the earliest time unit in the first time window is the time unit indicated by the PUCCH resource indicator field in the first signaling of this application.

[0315] As an example, the start time of the earliest time unit in the first time window is not earlier than the end time of the first air interface resource pool in the time domain; the first signaling indicates the time interval between the end time of the time unit to which the end time of the first air interface resource pool in the time domain belongs and the end time of the earliest time unit in the first time window.

[0316] As an example, the total number of time units included in the first time window is determined according to the configuration of higher-layer signaling.

[0317] As one embodiment, the total number of time units included in the first time window is associated with a higher-level parameter, which is used to indicate the maximum time limit for which a HARQ-ACK for an SPS PDSCH can be delayed.

[0318] As an example, the cutoff time of the first time window is the latest time when the first HARQ-ACK bit block is allowed to be sent.

[0319] As an example, the cutoff time of the first time window is the latest time when the second signal is allowed to be sent.

[0320] As an example, the last time unit in the first time window is the latest time unit that is allowed for delayed transmission of the first HARQ-ACK bit block.

[0321] As an example, the time domain resources occupied by the target air interface resource pool belong to the earliest first type of time unit in the first time window.

[0322] As an example, the earliest of the first type of time units in the first time window includes the time domain resources occupied by the target air interface resource pool.

[0326] As an example, a first type of time unit is a time unit that includes the time domain resources occupied by a PUCCH that can be used to transmit the first HARQ-ACK bit block.

[0327] As an example, when a time unit cannot be used to transmit the first HARQ-ACK bit block, the time unit is not the first type of time unit.

[0328] As an example, a time unit is not a first type of time unit when it does not include the time domain resources occupied by the PUCCH that can be used to transmit the first HARQ-ACK bit block.

[0329] As an example, in the first time window, whether a time unit is a first type of time unit is determined based on a semi-static configuration of the time slot format.
