[0001] This application claims priority to Chinese Patent Application No. 202411659893.0, filed on November 19, 2024, entitled “A method and apparatus for use in a wireless communication node in relation to HARQ-ACK information”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to transmission methods and apparatus in wireless communication systems, and in particular to methods and apparatus for transmitting wireless signals in non-terrestrial network communication systems. Background Technology

[0003] In existing NR (New Radio) systems, the DMRS (Demodulation Reference Signal) and PUCCH (Physical Uplink Control Channel) of PUSCH (Physical Uplink Shared Channel) support multiplexing of multiple antenna ports / multiple users through orthogonal sequences.

[0004] In December 2023, the 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network) #102 meeting decided to study the use of orthogonal sequences to support multiplexing of PUSCH in the "Non-Terrestrial Network (NTN) for NR (New Radio)" research project (Work Item, WI). In other words, multiple users need to transmit PUSCH with orthogonal code domains within the same time-frequency resources. This multiplexing technology can significantly improve uplink capacity and throughput. Summary of the Invention

[0005] After introducing PUSCH transmission with orthogonal sequences, determining the validity of HARQ-ACK (Hybrid Automatic Repeat Request ACK) feedback information is a crucial issue to consider in system design optimization; this application discloses a solution to this problem. It should be noted that this application is applicable to various wireless communication scenarios, such as non-terrestrial network (NTN) and terrestrial network (TN) communication scenarios, achieving similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to non-terrestrial network and terrestrial network communication scenarios) helps 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.

[0006] Where necessary, the interpretation of terms used in this application may be referenced to the descriptions in the 3GPP specification protocols TS37 and TS38 series.

[0007] This application discloses a method used in a terminal, characterized by comprising:

[0008] Receive the first signaling and the second signaling, wherein the second signaling indicates the first HARQ-ACK information;

[0009] The first transport block is transmitted in at least one of the multiple time slots;

[0010] Wherein, the first signaling is used to determine the plurality of time slots, the first transport block corresponds to the first HARQ process, and the validity of the first HARQ-ACK information for the first transport block depends on the start time domain position of the second signaling and the first configuration, the first configuration being the configuration of the PUSCH orthogonal sequence.

[0011] As an example, the problem to be solved by this application includes: how to determine the timing relationship between PUSCH and HARQ feedback when orthogonal sequences are applied.

[0012] As an example, the problem this application aims to solve includes: how to determine the validity of the received first HARQ-ACK information in a scenario where an orthogonal sequence of PUSCH is configured.

[0013] As an example, the advantages of the above method include: it facilitates multiple users occupying the same time-frequency resources, and improves uplink capacity and throughput.

[0014] As an example, the advantages of the above method include: compatibility with existing 3GPP protocols.

[0015] As an example, the advantages of the above method include: it facilitates direct HARQ feedback of uplink data, thereby improving the reliability of uplink transmission.

[0016] As an example, the benefits of the above method include improved robustness of HARQ feedback.

[0017] According to one aspect of this application, the above method is characterized in that,

[0018] The value of the first HARQ-ACK message is ACK; the first HARQ-ACK message is valid for the first transport block when the first symbol received by the PDCCH providing the second signaling is at least D symbols later than the first target symbol;

[0019] Wherein, the first target symbol depends on the first configuration, and D is a configurable non-negative integer.

[0020] As an example, the features of the above method include: clarifying the timing relationship between PUSCH and HARQ feedback using orthogonal sequences, that is, needing to satisfy the constraint of minimum HARQ timing (i.e., the D symbols), which improves the robustness of HARQ feedback.

[0021] As an example, the features of the above method include: defining the minimum HARQ timing (i.e., the D symbols) according to the configuration of the PUSCH orthogonal sequence. Such features can better support the joint processing of multiple PUSCH repetitions (i.e., a PUSCH OCC group) and improve the reliability of PUSCH transmission.

[0022] According to one aspect of this application, the above method is characterized in that,

[0023] The first target symbol is the last symbol of the first resource pool group, which includes more than one resource pool. The more than one resource pool in the first resource pool group is located in different time slots of the plurality of time slots. Each resource pool in the first resource pool group is for the first transport block. The first resource pool group depends on the first configuration.

[0024] As an example, the features of the above method include: In the existing 3GPP standard, the first target symbol is the last symbol of the earliest resource pool in the first resource pool group, which is incompatible with the joint processing of multiple PUSCH repetitions (that is, a PUSCH OCC group), which will lead to insufficient transport block decoding time, thereby affecting the timing of HARQ feedback.

[0025] As an example, the features of the above method include: in scenarios where orthogonal sequences of PUSCH are configured, in order to better accommodate the joint processing of multiple PUSCH repetitions (i.e., a PUSCH OCC group), a simple and effective method to modify the 3GPP standard is to start feeding back HARQ-ACK information from the Dth symbol after the last symbol of the first resource pool group. This feature is beneficial for supporting the joint processing of multiple PUSCH repetitions (i.e., a PUSCH OCC group) and improves the reliability of PUSCH transmission.

[0026] As an example, the benefits of the above method include improved robustness of HARQ feedback.

[0027] According to one aspect of this application, the above method is characterized in that,

[0028] The first target symbol is the last symbol of the first resource pool group only when the length of the PUSCH orthogonal sequence determined according to the first configuration is greater than the first threshold.

[0029] The first threshold is configurable or predefined.

[0030] As an example, the features of the above method include: whether the first target symbol is the last symbol of the first resource pool group depends on the (implicit) indication of the first configuration.

[0031] As an example, the advantages of the above method include: reduced signaling overhead.

[0037] As an example, the features of the above method include: whether the first target symbol is the last symbol of the first resource pool group depends on the (explicit) indication of the first information block.

[0038] As an example, the advantages of the above method include: improving the configuration flexibility of the terminal and reducing the implementation complexity of the terminal.

[0039] According to one aspect of this application, the above method is characterized in that,

[0041] As an example, the advantages of the above method include: it facilitates full utilization of the content already defined in the 3GPP protocol, and the amount of work required for standardization is small.

[0042] According to one aspect of this application, the above method is characterized in that,

[0044] Wherein, the first PUSCH uses a first orthogonal sequence, and the first orthogonal sequence is a PUSCH orthogonal sequence.

[0045] As an example, the above method is applicable to scenarios where PUSCH is dynamically scheduled in DCI format, in which transport blocks are transmitted in a slot aggregation manner.

[0046] According to one aspect of this application, the above method is characterized by comprising:

[0047] Send first capability information, which indicates the maximum length supported by the terminal;

[0048] The length of the PUSCH orthogonal sequence determined according to the first configuration depends on the maximum length supported by the terminal.

[0049] As an example, the advantages of the above method include: it facilitates different terminals reporting different code division multiplexing capabilities, and it enables base stations to perform more flexible resource scheduling.

[0050] As an example, the advantages of the above method include: it helps the base station to better match users based on the reported capability information, thereby improving the matching success rate.

Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3 shows the radio protocol architecture for the control plane 300 in 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 is above PHY301 and is responsible for the link between the first communication node device and the second communication node device, as well as between the two UEs, through PHY301. 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. PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and provides cross-area mobility support. 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).

[0233] Example 4

[0234] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to 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.

[0235] 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.

[0236] 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.

[0237] 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), 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 and non-codebook-based precoding, and beamforming processing, generating 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 subsequently performs an inverse fast Fourier transform (IFFT). The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol stream using an IFFT (Instantaneous Transformation) technique. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into an RF stream, which is then provided to different antennas 420.

[0238] 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 that stores program code and data.

[0239] The memory 460 may be referred to as computer-readable media. During 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 transmission 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 L2. Various control signals may also be provided to layer L3 for L3 processing.

[0240] 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.

[0241] 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.

[0379] Example 8 illustrates a schematic diagram showing that, according to an embodiment of this application, the first symbol of the PDCCH receiving the second signaling is at least D symbols later than the first target symbol, as shown in Figure 8. In Figure 8, the rectangle filled with a large grid represents the first target symbol, the box with bold borders represents the PDCCH receiving the second signaling, and the portion filled with diamond lines within the box with bold borders represents the first symbol of the PDCCH receiving the second signaling.

[0382] As an example, the first symbol of a PDCCH reception is the earliest symbol occupied in the time domain for that PDCCH reception.

[0383] As an example, D is configurable.

[0385] As an example, D is indicated by the RRC parameter.

[0386] As an example, D is a value determined by a parameter whose name includes cg-minDFI-Delay.

[0387] As an example, D is the value indicated by the parameter cg-minDFI-Delay-r16.

[0388] As an example, the value indicated by the parameter cg-minDFI-Delay-r16 is a positive integer multiple of 7 or 14.

[0389] As an example, D is the value indicated by parameter cg-minDFI-Delay-r16 plus 1.

[0393] As an example, D is the value indicated by parameter cg-minDFI-Delay-v1710 minus 1.

[0394] As an example, D is a non-negative integer, and D is expressed in symbols.

[0395] As an example, if the first symbol received by the PDCCH providing the second signaling is at least D symbols later than the first target symbol, then the first HARQ-ACK information is valid for the first transport block; otherwise, the first HARQ-ACK information is invalid for the first transport block.

[0396] As an example, if the first symbol received by the PDCCH providing the second signaling is at least D symbols later than the first target symbol, then the first HARQ-ACK information is valid for the first transport block; if the first symbol received by the PDCCH providing the second signaling is earlier than the first target symbol, then the first HARQ-ACK information is invalid for the first transport block; if the first symbol received by the PDCCH providing the second signaling is less than D symbols later than the first target symbol, then the first HARQ-ACK information is invalid for the first transport block.

[0397] As an example, if the first symbol received by the PDCCH providing the second signaling is after the first target symbol and the interval between them is not less than D symbols, then the first HARQ-ACK information is valid for the first transport block; if the first symbol received by the PDCCH providing the second signaling is before the first target symbol, then the first HARQ-ACK information is invalid for the first transport block; if the first symbol received by the PDCCH providing the second signaling is after the first target symbol and the interval between them is less than D symbols, then the first HARQ-ACK information is invalid for the first transport block.

[0398] As an example, "one symbol is earlier / later than another symbol" means that the one symbol precedes / follows the other symbol.

[0399] As one embodiment, one symbol being earlier / later than another symbol includes: the start time of the one symbol being earlier / later than the start time of the other symbol.

[0400] As one embodiment, one symbol being earlier / later than another symbol includes: the cutoff time of the one symbol being earlier / later than the cutoff time of the other symbol.

[0401] As an example, the first reference symbol is the Dth time-domain symbol following the first target symbol; if the first symbol received by the PDCCH providing the second signaling is after the first reference symbol, then the first HARQ-ACK information is valid for the first transport block; otherwise, the first HARQ-ACK information is invalid for the first transport block.

[0402] As an example, the first reference symbol is the Dth time-domain symbol following the first target symbol; if the first symbol received by the PDCCH providing the second signaling is after the first reference symbol, then the first HARQ-ACK information is valid for the first transport block; if the first symbol received by the PDCCH providing the second signaling is before the first reference symbol, then the first HARQ-ACK information is invalid for the first transport block.

[0403] As an example, the first target symbol depends on the first configuration.

[0404] As an example, the first target symbol is the last symbol of the first resource pool group, which depends on the first configuration.

[0405] As an example, the first target symbol is the last symbol of the first resource pool group, and the first resource pool group applies a first orthogonal sequence, which is an orthogonal sequence of PUSCH.

[0406] As an example, the first target symbol is the last symbol of the first resource pool group, or the last symbol of the earliest resource pool in the first resource pool group.

[0407] As an example, whether the first target symbol is the last symbol of the first resource pool group depends on the length of the PUSCH orthogonal sequence determined according to the first configuration.

[0408] As one embodiment, whether the first target symbol is the last symbol of the first resource pool group depends on the indication of the first information block.

[0409] Example 9

[0410] Example 9 illustrates a schematic diagram showing whether a first target symbol is the last symbol of a first resource pool group according to an embodiment of the present application depends on the length of a PUSCH orthogonal sequence determined according to a first configuration, as shown in Figure 9.

[0411] In Example 9, when the length of the PUSCH orthogonal sequence determined according to the first configuration is greater than the first threshold, the first target symbol is the last symbol of the first resource pool group; when the length of the PUSCH orthogonal sequence determined according to the first configuration is not greater than the first threshold, the first target symbol is the last symbol of the earliest resource pool in the first resource pool group; the first threshold is configurable or predefined.

[0412] As an example, the features of the above method include: whether the first target symbol is the last symbol of the first resource pool group depends on the (implicit) indication of the first configuration.

[0413] As an example, the characteristics of the above method include: applying long PUSCH orthogonal sequences will cause serious inter-user interference, and only by jointly processing multiple PUSCH repetitions (that is, a PUSCH OCC group) can the transport block be correctly decoded.

[0414] As an example, the features of the above method include: applying short PUSCH orthogonal sequences only introduces slight inter-user interference, and decoding the transport block per PUSCH repetition can reduce processing latency and improve the timeliness of HARQ-ACK feedback.

[0415] As an example, the features of the above method include: if the transport block is decoded repeatedly for each PUSCH, then the first target symbol is the last symbol of the first resource pool group; if the transport block is decoded repeatedly for multiple PUSCHs, then the first target symbol is the last symbol of the earliest resource pool in the first resource pool group.

[0416] As an example, the advantages of the above method include: reduced signaling overhead.

[0417] As an example, the advantages of the above method include: reducing processing latency and improving the timeliness of HARQ-ACK feedback while ensuring the transmission performance of PUSCH.

[0418] When the length of the PUSCH orthogonal sequence determined according to the first configuration is not greater than the second threshold, the first target symbol is the last symbol of the first resource pool group; when the length of the PUSCH orthogonal sequence determined according to the first configuration is greater than the second threshold, the first target symbol is the last symbol of the earliest resource pool in the first resource pool group; the second threshold is configurable or predefined.

[0419] As an example, the features of the above method include: the application of short PUSCH orthogonal sequences only introduces slight inter-user interference, and it has good BLER performance when multiple PUSCH repetitions (i.e., an OCC group of PUSCH) are processed together.

[0420] As an example, the characteristics of the above method include: applying long PUSCH orthogonal sequences can cause serious inter-user interference; when multiple PUSCH repetitions (i.e., a PUSCH OCC group) are processed together, the BLER performance degrades more significantly; an effective PUSCH decoding method is to decode the transport block per PUSCH repetition and then improve the reliability of PUSCH transmission through PUSCH time slot aggregation.

[0421] As an example, the features of the above method include: if the transport block is decoded repeatedly for each PUSCH, then the first target symbol is the last symbol of the first resource pool group; if the transport block is decoded repeatedly for multiple PUSCHs, then the first target symbol is the last symbol of the earliest resource pool in the first resource pool group.

[0422] As an example, when the first type of event does not occur within the first resource pool group, the first target symbol is the last symbol of the first resource pool group; when the first type of event occurs within the first resource pool group, the first target symbol is the last symbol of the earliest resource pool in the first resource pool group; the first type of event is an event that causes power consistency and phase continuity to be lost.

[0423] As an example, the features of the above method include: whether the first target symbol is the last symbol of the first resource pool group depends on the occurrence of the first type of event.

[0424] As an example, the features of the above method include: if the first type of event does not occur within the first resource pool group, and power consistency and phase continuity cannot be maintained, then multiple PUSCHs repeatedly decode the transport block; if the first type of event does not occur within the first resource pool group, and power consistency and phase continuity can be maintained, then each PUSCH repeatedly decodes the transport block.

[0425] As an example, the first type of event is based on downlink slots, downlink reception, or downlink monitoring of tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated.

[0426] As an example, the first type of event is an interval between any two adjacent resource pools of the first signal that exceeds 13 symbols for a normal cyclic prefix or 11 symbols for an extended cyclic prefix.

[0427] As an example, the first type of event is when the interval between any two adjacent resource pools in the first resource pool group does not exceed 13 symbols, but other uplink transmissions are scheduled between any two adjacent resource pools in the first resource pool group.

[0428] As an example, the first type of event discards or cancels one transmission of the first transport block in accordance with Articles 9, 11.1 and 11.2A of TS 38.214.

[0429] As an example, the first type of event is a transmission of the first transport block that is discarded or canceled in accordance with Clause 5.34.3 of TS 38.321.

[0430] As an example, the first type of event is when the first resource pool group corresponds to two different SRS resource sets according to clause 6.1.2.1 of TS 38.214.

[0431] As an example, the first type of event is an uplink timing adjustment in response to a timing advance command in accordance with Section 4.2 of TS 38.213.

[0432] As an example, the first type of event is frequency hopping.

[0433] As an example, if the terminal sends the first capability information, then the first target symbol is the last symbol of the first resource pool group; if the terminal does not send the first capability information, then the first target symbol is the last symbol of the earliest resource pool in the first resource pool group.

[0434] As an example, if the terminal supports 3GPP R19 or a higher version, then the first target symbol is the last symbol of the first resource pool group; if the terminal supports 3GPP R18 or a lower version, then the first target symbol is the last symbol of the earliest resource pool in the first resource pool group.

[0435] Example 10

[0436] Example 10 illustrates a schematic diagram showing whether a first target symbol is the last symbol of a first resource pool group according to an embodiment of the present application depends on the indication of a first information block, as shown in Figure 10.

[0437] In embodiment 10, when the first information block indicates a second configuration, the first target symbol is the last symbol of the first resource pool group; when the first information block indicates a third configuration, the first target symbol is the last symbol of the earliest resource pool in the first resource pool group; wherein, the second configuration is a configuration for transmission block decoding, and the third configuration is a configuration for transmission block decoding.

[0438] As an example, the features of the above method include: whether the first target symbol is the last symbol of the first resource pool group depends on the (explicit) indication of the first information block.

[0439] As an example, the advantages of the above method include: improving the configuration flexibility of the terminal and reducing the implementation complexity of the terminal.

[0440] As one embodiment, the first information block indicates one of a plurality of configurations, the plurality of configurations including the second configuration and the third configuration; in the second configuration, the first target symbol is the last symbol of the first resource pool group; in the third configuration, the first target symbol is the last symbol of the earliest resource pool in the first resource pool group.

[0441] As an example, the second information block indicates one of the second configuration and the third configuration.

[0442] As one embodiment, the second information block includes a first indication field, the value range of which includes only one value; this value in the value range of the first indication field indicates the second configuration.

[0443] As one embodiment, the first indication field in the second information block is absent, and the second information block indicates the second configuration.

[0444] As an example, the second configuration and the third configuration correspond to different transport block decoding configurations.

[0445] As an example, when the first information block indicates the second configuration, each resource pool in the first resource pool group jointly decodes the first transport block; when the first information block indicates the third configuration, each resource pool in the first resource pool group independently decodes the first transport block.

[0446] As an example, when the first information block indicates the second configuration, each resource pool in the first resource pool group jointly treats the first transport block; when the first information block indicates the third configuration, each resource pool in the first resource pool group independently treats the first transport block.

[0447] As one embodiment, when the first information block indicates the second configuration, each resource pool in the first resource pool group coherently decodes the first transport block; when the first information block indicates the third configuration, each resource pool in the first resource pool group incoherently decodes the first transport block.

[0467] As an example, if the first symbol received by the PDCCH providing the second signaling is after the second target symbol and the interval between them is not less than D symbols, then the first HARQ-ACK information is valid for the first transport block; if the first symbol received by the PDCCH providing the second signaling is before the second target symbol, then the first HARQ-ACK information is invalid for the first transport block; if the first symbol received by the PDCCH providing the second signaling is after the second target symbol and the interval between them is less than D symbols, then the first HARQ-ACK information is invalid for the first transport block.

[0468] As an example, "one symbol is earlier / later than another symbol" means that the one symbol precedes / follows the other symbol.
