Description

Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, particularly to a method and apparatus for transmitting wireless signals in a wireless communication system supporting a cellular network. Background Art

[0002] In the existing NR (New Radio) system, spectrum resources are statically divided into FDD (Frequency Division Duplex) spectrum and TDD (Time Division Duplex) spectrum. For the TDD spectrum, both the base station and the UE (User Equipment) operate in a half-duplex mode. This half-duplex mode avoids self-interference and can mitigate the impact of cross-link interference (CLI), but it also brings problems such as decreased resource utilization and increased latency. To address these issues, supporting a flexible duplex mode or variable link directions (uplink or downlink or flexible) on the TDD spectrum or FDD spectrum becomes a possible solution. At the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) 1#103e meeting, research work on duplex technology was agreed upon, and in particular, the sub-band non-overlapping full-duplex (SBFD) mode at the gNB (NR Node B) side was proposed. In this mode, the same symbol is used for uplink in some frequency resources and for downlink in other frequency resources, thus improving resource utilization and reducing latency.

[0003] HARQ-ACK (Hybrid Automatic Repeat reQuest-ACKnowledgement) feedback is an effective means to improve communication reliability. Summary of the Invention

[0004] How to enhance HARQ-ACK feedback is an important issue in wireless communication; this application discloses a solution to the above problem. It should be noted that this application can be applied to a variety of wireless communication scenarios, such as scenarios using the SBFD mode, scenarios using other types of full-duplex modes other than SBFD, scenarios using a more flexible duplex mode, scenarios that only support the half-duplex mode, etc., and achieve similar technical effects. In addition, using a unified solution for different scenarios (including but not limited to scenarios using the SBFD mode, scenarios using other types of full-duplex modes other than SBFD, scenarios using a more flexible duplex mode, scenarios that only support the half-duplex mode) helps to reduce hardware complexity and cost, or improve performance. Without conflict, the embodiments and features in the embodiments of this application in any node can be applied to any other node. Without conflict, the embodiments and features in the embodiments of this application can be combined with each other arbitrarily.

[0177] As an example, the size of the first HARQ-ACK bit block is determined as the result of taking the modulus of the ceiling of the sum of a reference value and 37.1 with respect to the result of rounding down to the nearest integer in the 1.6th power of the number of symbols indicated as the downlink by the uplink-downlink TDD configuration signaling in the first time-domain resource; when the first time-domain resource overlaps with at least one of the first type of physical uplink channels, the reference value is equal to the result of rounding down to the nearest integer in the 2.7th power of the number of symbols included in the first time-domain resource; when the first time-domain resource does not overlap with the first type of physical uplink channels, the reference value is equal to 3.

[0178] As a sub-example of the above example, the first HARQ-ACK bit block includes HARQ-ACK bits for transport blocks in the latest K PDSCHs received before the transmission of the first HARQ-ACK bit block, where K is equal to the size of the first HARQ-ACK bit block.

L1 is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 will be referred to as PHY301 in this article. 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 and between two UEs through PHY301.

[0206] Example 4

[0207] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in the appendix Figure 4 as shown. Figure 4 It is a block diagram of a first communication device 410 and a second communication device 450 that communicate with each other in an access network.

[0208] The first communication device 410 includes a controller / processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter / receiver 418, and an antenna 420.

[0209] 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.

[0210] 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 the functionality of the L2 layer. 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 for the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal constellations 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)). The multi-antenna transmit processor 471 performs digital space 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. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multi-carrier symbol streams. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol streams. Each transmitter 418 converts the baseband multi-carrier symbol streams provided by the multi-antenna transmit processor 471 into radio frequency streams and then provides them to different antennas 420.

[0211] 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 signals 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 multi-carrier symbol stream and provides it to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the Fast Fourier Transform (FFT) to convert the baseband multi-carrier 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 receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial stream destined for the second communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the first communication device 410 on the physical channel. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0212] 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 an upper layer data packet to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function described at the first communication device 410 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, and implements L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the first communication device 410. A transmit processor 468 performs modulation mapping and channel coding processing, and a multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated spatial streams into a multi-carrier / single-carrier symbol stream, and after an analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides it to different antennas 452 via a transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and then provides it to the antenna 452.

[0213] In the transmission from the second communication device 450 to the first communication device 410, the functions at the first communication device 410 are similar to the receive function described at the second communication device 450 in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement L1 layer functions. A controller / processor 475 implements 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 a computer-readable medium. In the transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packet from the UE 450. The upper layer data packet from the controller / processor 475 may be provided to the core network.

[0241] As a sub-embodiment of Embodiment 5, the target set is determined for index n D and index k, where the index n D is the index of the DL slot overlapping with the UL slot, and the index k is the index of the slot timing value K 1,k ; the first time-domain resource is the PDSCH time resource for slot n 0,k +n D , where n 0,k represents the DL slot with the smallest index among the DL slots (DL slots) overlapping with the UL slot n U -K 1,k , and n U represents the slot in which the first HARQ-ACK bit block is transmitted.

[0242] As an example, the first node U1 is the first node in the present application.

[0243] As an example, the second node U2 is the second node in the present application.

[0244] As an example, the first node U1 is a UE.

[0245] As an example, the second node U2 is a base station.

[0246] As an example, the air interface between the second node U2 and the first node U1 is the Uu interface.

[0247] As an example, the air interface between the second node U2 and the first node U1 includes a cellular link.

[0248] As an example, the air interface between the second node U2 and the first node U1 includes a radio interface between a base station device and a user equipment.

[0249] As an example, the air interface between the second node U2 and the first node U1 includes a radio interface between a satellite device and a user equipment.

[0250] As an example, the air interface between the second node U2 and the first node U1 includes a radio interface between a relay device and a user equipment.

[0251] As an example, the first HARQ-ACK bit block does not include HARQ-ACK bits for the PDSCH scheduled by DCI.

[0252] As an example, the first HARQ-ACK bit block includes at least one HARQ-ACK bit for the PDSCH scheduled by DCI.

[0253] As an example, the second node U1 receives the uplink and downlink TDD configuration signaling.

[0254] As an example, the second node U2 sends the uplink and downlink TDD configuration signaling.

[0255] As an example, the sending / receiving of the uplink and downlink TDD configuration signaling is before the configuration information of the PUCCH.

[0256] As an example, the sending / receiving in the uplink and downlink TDD configuration signaling is after the configuration information of the PUCCH.

[0257] As an example, the sending / receiving of the uplink-downlink TDD configuration signaling is before the determination of the first HARQ-ACK bit block.

[0258] As an example, at least one of the first type of physical uplink channels is configured by the second node for the first node.

[0259] As an example, at least one time domain resource allocation in the first time domain resource allocation set is configured by the second node for the first node.

[0260] As an example, the second node needs to make an assumption about the determination method of the first HARQ-ACK bit block to perform the reception of the first HARQ-ACK bit block.

[0261] As an example, the second node needs to make an assumption about the determination method of the target opportunity set to perform the reception of the first HARQ-ACK bit block.

[0262] As an example, the first node receives a PDSCH in an opportunity of candidate PDSCH reception included in the target opportunity set, and the first HARQ-ACK bit block includes HARQ-ACK bits for the transport block in this PDSCH.

[0263] As an example, the candidate PDSCH reception is for the transmitting end of the first HARQ-ACK bit block.

[0264] As an example, the size of the first HARQ-ACK bit block is determined as the result of taking the modulus of the ceiling of the product of the number of opportunities in the target opportunity set that meet a given condition and 7.3 with respect to the number of opportunities in the target opportunity set that do not meet the given condition; for any opportunity in the target opportunity set, the given condition is: the number of symbols indicated as downlink by the uplink-downlink TDD configuration signaling in the time slot where this opportunity is located is not greater than 6.

[0265] As a sub-example of the above example, the first HARQ-ACK bit block includes HARQ-ACK bits for the transport blocks in the latest K received PDSCHs before the sending of the first HARQ-ACK bit block, and K is equal to the size of the first HARQ-ACK bit block.

[0266] As an example, the size of the first HARQ-ACK bit block is equal to the total number of opportunities included in the target opportunity set.

[0267] As an example, the size of the first HARQ-ACK bit block is greater than the total number of opportunities included in the target opportunity set.

[0268] As an example, the size of the first HARQ-ACK bit block is equal to twice the total number of opportunities included in the target opportunity set.

[0269] As an example, the size of the first HARQ-ACK bit block is greater than twice the total number of opportunities included in the target opportunity set.

[0270] As an example, the first time-domain resource overlaps with one of the first type of physical uplink channels, and the first node transmits this first type of physical uplink channel that overlaps with the first time-domain resource.

[0271] As an example, transmitting one of the first type of physical uplink channels means: transmitting UCI (Uplink control information) or a transport block in this first type of physical uplink channel.

[0272] Example 6

[0273] Example 6 illustrates a schematic diagram showing that the determination of the first HARQ-ACK bit block according to an embodiment of the present application depends on the target opportunity set, as shown in the attached Figure 6 figure.

[0274] In Example 6, the first HARQ-ACK bit block includes at least one HARQ-ACK bit for each opportunity in the target opportunity set.

[0275] As an example, the advantages of the above method include: strong robustness of HARQ-ACK feedback.

[0276] As an example, during the process of determining the first HARQ-ACK bit block: for each opportunity in the target opportunity set, the first node adds at least one HARQ-ACK bit to the first HARQ-ACK bit block.

[0277] As an example, for an opportunity in the target opportunity set: if there is a PDSCH reception in this opportunity, the HARQ-ACK bit for this opportunity indicates whether the transport block in the PDSCH reception is correctly decoded, otherwise, the HARQ-ACK bit for this opportunity indicates NACK.

[0278] As an example, for an opportunity in the target opportunity set: If the first node receives a transport block in this opportunity, the HARQ-ACK bit for this opportunity indicates whether the transport block is correctly decoded or not; otherwise, the HARQ-ACK bit for this opportunity indicates NACK.

[0279] As an example, for an opportunity in the target opportunity set: If the first node receives a transport block or a CBG in this opportunity, the HARQ-ACK bit for this opportunity indicates whether the transport block or the CBG is correctly decoded or not (a CBG is correctly decoded means that all code blocks of this CBG are correctly received); otherwise, the HARQ-ACK bit for this opportunity indicates NACK.

[0280] As an example, for an opportunity in the target opportunity set: If there is a PDSCH reception in this opportunity, the HARQ-ACK bit for this opportunity indicates whether the transport block in the PDSCH reception is correctly decoded or not; if there is an SPS (Semi-Persistent Scheduling) PDSCH release(s) or a TCI (Transmission Configuration Indicator) state update in this opportunity, the HARQ-ACK bit for this opportunity indicates ACK; otherwise, the HARQ-ACK bit for this opportunity indicates NACK.

[0281] As an example, in this application, the determination of the first HARQ-ACK bit block depends on the target opportunity set, including: the determination of the first HARQ-ACK bit block depends on the cardinality of the target opportunity set.

[0282] As an example, M is the cardinality of the target opportunity set, which defines the total number of opportunities in the target opportunity set; for any non-negative integer m less than M (the m is the index of the opportunity in the target opportunity set), perform the following operation: Assign the HARQ-ACK bit of the first cell to a bit to form the first HARQ-ACK bit block.

[0283] As a sub-example of the above example, for any non-negative integer m less than M, the HARQ-ACK bit of the corresponding first cell is the HARQ-ACK bit for opportunity m.

[0284] As an example, for any positive integer n less than M, in the first HARQ-ACK bit block: the HARQ-ACK bit corresponding to opportunity n-1 in the target opportunity set is adjacent to the HARQ-ACK bit corresponding to opportunity n in the target opportunity set, and the HARQ-ACK bit corresponding to the opportunity n-1 in the target opportunity set is arranged before the HARQ-ACK bit corresponding to the opportunity n in the target opportunity set.

[0285] As an example, the first HARQ-ACK bit block includes only one HARQ-ACK bit for each opportunity in the target opportunity set.

[0286] As an example, the first HARQ-ACK bit block includes 2 HARQ-ACK bits for each opportunity in the target opportunity set, and the 2 HARQ-ACK bits corresponding to any opportunity in the target opportunity set are adjacent to each other.

[0287] As an example, the HARQ-ACK bits for each opportunity in the target opportunity set are the HARQ-ACK bits of the first cell.

[0288] As an example, the target opportunity set includes opportunities for candidate PDSCH reception.

[0289] As an example, each opportunity in the target opportunity set is: an opportunity for candidate PDSCH reception.

[0290] As an example, one opportunity in the target opportunity set is: one of the opportunities for candidate PDSCH reception, or SPS PDSCH release, or TCI state update.

[0291] As an example, the target opportunity set is determined for the first cell.

[0292] As an example, the first cell is any serving cell among at least one serving cell configured for the first node; the first HARQ-ACK bit block includes the HARQ-ACK bits of each serving cell among the at least one serving cell.

[0293] As an example, the first node is configured with multiple serving cells.

[0294] As an example, when the first HARQ-ACK bit block includes HARQ-ACK bits of multiple serving cells, the HARQ-ACK bits of different serving cells are arranged in ascending order of the corresponding serving cell indices.

[0295] Example 7

[0296] Example 7 illustrates a schematic diagram of the relationship between the target opportunity set and the target set according to an embodiment of the present application, as shown in the appendix Figure 7 as shown.

[0297] In Example 7, the determination of the target opportunity set depends on whether the target set is an empty set.

[0298] As an example, the determination of the target opportunity set depends on whether the target set is an empty set, including:

[0299] When the first condition set is satisfied, there is at least one opportunity included in the target opportunity set based on the satisfaction of the first condition set; the first condition set includes: the target set is not an empty set.

[0300] As an example, only when the first condition set is satisfied, there is at least one opportunity included in the target opportunity set based on the satisfaction of the first condition set; the first condition set includes: the target set is not an empty set.

[0301] As an example, when the first condition set is satisfied, the target opportunity set includes opportunities for candidate PDSCH reception for index n D and index k; the first condition set includes: the target set is not an empty set.

[0302] As an example, only when the first condition set is satisfied, the target opportunity set includes opportunities for candidate PDSCH reception for index n D and index k; the first condition set includes: the target set is not an empty set.

[0303] As an example, the index n D is the index of the DL time slot overlapping with the UL time slot, and the index k is the index of a time slot timing value.

[0304] As an example, the opportunity for candidate PDSCH reception for the index n D and the index k is in time slot n 0,k +n D where the index n D is the index of the DL time slot overlapping with the UL time slot, and the n 0,kIndicates the DL slot overlapping with UL slot n U -K 1,k The DL slot with the smallest index among the overlapping DL slots, where the index k is the slot timing value K 1,k of, and the n U Indicates the slot in which the transmission of the first HARQ-ACK bit block is located.

[0305] As an example, when the first set of conditions is satisfied, the target opportunity set includes a first opportunity; the first opportunity is an opportunity for receiving a candidate PDSCH for indices n D and index k, and one HARQ-ACK bit in the first HARQ-ACK bit block is the HARQ-ACK bit for the first opportunity, and this HARQ-ACK bit in the first HARQ-ACK bit block indicates whether there is a correctly received transport block in slot n 0,k +n D where the index n D is the index of the DL slot overlapping with the UL slot, and the n 0,k Indicates the DL slot overlapping with UL slot n U -K 1,k The DL slot with the smallest index among the overlapping DL slots, where the index k is the slot timing value K 1,k of, and the n U Indicates the slot in which the transmission of the first HARQ-ACK bit block is located.

[0306] As an example, a PDSCH is received in slot n 0,k +n D and one HARQ-ACK bit in the first HARQ-ACK bit block indicates whether the transport block in this PDSCH is correctly decoded, and this HARQ-ACK bit in the first HARQ-ACK bit block is the HARQ-ACK bit for the first opportunity, and the first opportunity is an opportunity for receiving a candidate PDSCH for the index n D and the index k.

[0307] As an example, the index n D is the index of the DL slot overlapping with the UL slot, and the n 0,k Indicates the DL slot overlapping with UL slot n U -K 1,k The DL slot with the smallest index among the overlapping DL slots, where the index k is the slot timing value K 1,k of, and the n UIndicates the time slot in which the transmission of the first HARQ-ACK bit block is located.

[0308] As an embodiment, when the first set of conditions is satisfied, the target opportunity set includes a first opportunity; the first opportunity is for index n D and index k, an opportunity for candidate PDSCH reception or SPS PDSCH release or TCI state update; one HARQ-ACK bit in the first HARQ-ACK bit block is the HARQ-ACK bit for the first opportunity, and this HARQ-ACK bit in the first HARQ-ACK bit block indicates whether there is a correctly received transport block or DCI format in time slot n 0,k +n D where index n D is the index of the DL time slot overlapping with the UL time slot, and the n 0,k represents the DL time slot with the smallest index among the DL time slots (DL slots) overlapping with UL time slot n U -K 1,k where index k is the index of the time slot timing value K 1,k and the n U indicates the time slot in which the transmission of the first HARQ-ACK bit block is located.

[0309] As an embodiment, when the first set of conditions is not satisfied, there is no opportunity included in the target opportunity set based on the satisfaction of the first set of conditions; the first set of conditions includes: the target set is not an empty set.

[0310] As an embodiment, when the first set of conditions is not satisfied, the target opportunity set does not include an opportunity for candidate PDSCH reception for the index n D and the index k; the first set of conditions includes: the target set is not an empty set.

[0311] As an embodiment, when the first set of conditions is not satisfied, the target opportunity set does not include an opportunity for candidate PDSCH reception or SPS PDSCH release or TCI state update for the index n D and the index k; the first set of conditions includes: the target set is not an empty set.

[0312] As an embodiment, the first set of conditions includes at least one condition; the target set is not an empty set is one of the at least one condition; the satisfaction of the first set of conditions means that each condition in the first set of conditions is satisfied.

[0313] As an example, the first set of conditions only includes: the target set is not an empty set.

[0314] As an example, whether the target set is an empty set depends on whether the first time-domain resource overlaps with the first type of physical uplink channel.

[0315] As an example, whether the target set is an empty set depends on whether the first time-domain resource overlaps with the first type of physical uplink channel, including:

[0316] The first time-domain resource allocation set includes a target time-domain resource allocation, and the first time-domain resource depends on the target time-domain resource allocation; when the first time-domain resource overlaps with the first type of physical uplink channel, the target set is obtained by removing at least the target time-domain resource allocation from the first time-domain resource allocation set.

[0317] Example 8

[0318] Example 8 exemplifies an explanatory schematic diagram of whether the target set is an empty set depending on whether the first time-domain resource overlaps with the first type of uplink physical channel according to an embodiment of the present application, as shown in the appendix Figure 8 as shown.

[0319] In Example 8, the first time-domain resource allocation set includes a target time-domain resource allocation, and the first time-domain resource depends on the target time-domain resource allocation; when the first time-domain resource overlaps with the first type of physical uplink channel, the target set is obtained by removing at least the target time-domain resource allocation from the first time-domain resource allocation set.

[0320] As an example, the target time-domain resource allocation is any time-domain resource allocation in the first time-domain resource allocation set.

[0321] As an example, the target time-domain resource allocation is a row in the first time-domain resource allocation set.

[0322] As an example, the target time-domain resource allocation is: a row that defines at least the SLIV.

[0323] As an example, the target time-domain resource allocation is: a row that defines the slot offset, SLIV, and PDSCH mapping type.

[0324] As an example,

[0325] As an example, the first time-domain resource is derived from the target time-domain resource allocation.

[0326] As an example, the target time-domain resource allocation indicates the first time-domain resource.

[0327] As an example, the first time-domain resource is indicated by the SLIV defined in the target time-domain resource allocation.

[0328] As an example, the first time-domain resource is determined by the start symbol and the allocation length defined in the target time-domain resource allocation.

[0329] As an example, the first time-domain resource is for index n D and index k.

[0330] As an example, the first time-domain resource is a PDSCH time resource.

[0331] As an example, the first time-domain resource is the PDSCH time resource for slot n 0,k +n D of the PDSCH time resource.

[0332] As an example, the first time-domain resource is for the PDSCH time resource from slot n 0,k +n D −Q + 1 to slot n 0,k +n D of the PDSCH time resource, where Q is a configurable positive integer.

[0333] As an example, the index n D is the index of the DL slot overlapping with the UL slot, and the index k is the index of the slot timing value K 1,k ; the n 0,k represents the DL slot with the smallest index among the DL slots overlapping with the UL slot n U -K 1,k ; the n U represents the slot where the first HARQ-ACK bit block is sent.

[0334] As an example, the first time-domain resource is determined for index n D and index k to obtain the target set.

[0335] As an example, the first time-domain resource overlaps with the first type of physical uplink channel, including: at least one symbol of the first time-domain resource overlaps with the first type of physical uplink channel.

[0336] As an example, the first time-domain resource overlaps with the first type of physical uplink channel, including: at least one symbol of the first time-domain resource overlaps with one of the first type of physical uplink channels.

[0337] As an example, when one symbol of the first time-domain resource overlaps with at least one of the first type of physical uplink channels, the first time-domain resource overlaps with the first type of physical uplink channel.

[0338] As an example, the first time-domain resource does not overlap with the first type of physical uplink channel, including: any symbol of the first time-domain resource does not overlap with the first type of physical uplink channel.

[0339] As an example, in the present application, whether the first time-domain resource overlaps with / does not overlap with the first type of physical uplink channel is in terms of the time domain.

[0340] As an example, that one symbol of the first time-domain resource overlaps with / does not overlap with one of the first type of physical uplink channels means that this symbol of the first time-domain resource overlaps with / does not overlap with this first type of physical uplink channel in the time domain.

[0341] As an example, one symbol of the first time-domain resource refers to: one symbol included in the first time-domain resource.

[0342] As an example, the target set includes at least one time-domain resource allocation in the first time-domain resource allocation set, or, the target set is an empty set.

[0343] As an example, the target set is a subset of the first time-domain resource allocation set; if any condition in the second condition set is satisfied, the target set does not include the target time-domain resource allocation, otherwise, the target set includes the target time-domain resource allocation; one condition in the second condition set is: the first time-domain resource overlaps with the first type of physical uplink channel.

[0344] As an example, the second condition set includes only one condition.

[0345] As an example, the second condition set includes multiple conditions.

[0346] As an example, the second condition set further includes: at least one symbol of the first time-domain resource is configured as an uplink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated.

[0347] As an embodiment, the second set of conditions further includes: at least one symbol of the first time-domain resource overlaps with a symbol indicated as an uplink by the uplink-downlink TDD configuration signaling.

[0348] Example 9

[0349] Embodiment 9 exemplifies a target set according to an embodiment of the present application, index n D , index k, time slot timing value K 1,k , the first time-domain resource, n 0,k , n U and a schematic diagram of the relationship between the first HARQ-ACK bit block, as shown in the appendix Figure 9 .

[0350] In Embodiment 9, the target set is determined for index n D and index k. The index n D is the index of the DL time slot that overlaps with the UL time slot, and the index k is the index of the time slot timing value K 1,k ; the first time-domain resource is the PDSCH time resource for time slot n 0,k +n D . The n 0,k represents the DL time slot with the smallest index among the DL time slots (DL slots) that overlap with UL time slot n U -K 1,k , and the n U represents the time slot in which the first HARQ-ACK bit block is transmitted.

[0351] As an embodiment, the n D is any non-negative integer less than T, and the T is configurable.

[0352] As an embodiment, the n D is any non-negative integer less than T, and the T is equal to where the μ DL is the downlink subcarrier spacing configuration (downlink SCS (Subcarrier spacing) configuration), and the μ UL is the uplink subcarrier spacing configuration (uplink SCS configuration).

[0353] As an embodiment, the T is equal to 1.

[0354] As an example, based on the configuration, one UL (uplink) slot overlaps with T DL (downlink) slots, where T is greater than 1; index n D1 is the index of the DL slot overlapping with the UL slot, index n D2 is the index of the DL slot overlapping with the UL slot, the n D1 is less than the T, the n D2 is less than the T; the n D1 is less than the n D2 , the index n D1 The corresponding DL slot at the index n D2 is before the corresponding DL slot at the index n

[0355] As an example, the slot timing value K 1,k is any slot timing value in the first set of slot timing values

[0356] As an example, the index k is the slot timing value K 1,k in the first set of slot timing values arranged in descending order according to slot timing values

[0357] As an example, the first set of slot timing values includes at least one slot timing value

[0358] As an example, the first set of slot timing values is configurable

[0359] As an example, the first set of slot timing values includes slot timing values {1, 2, 3, 4, 5, 6, 7, 8}

[0360] As an example, the first set of slot timing values includes slot timing values {7, 8, 12, 16, 20, 24, 28, 32}

[0361] As an example, the first set of slot timing values includes slot timing values {13, 16, 24, 32, 40, 48, 56, 64}

[0362] As an example, the name of the signaling for configuring the first set of slot timing values includes dl-DataToUL-ACK

[0363] As an example, the target set is specifically determined for a given index n D and index k

[0364] As an example, the target set is specifically determined to determine whether the target opportunity set includes opportunities for receiving candidate PDSCHs for index n D and index k.

[0365] As an example, the first node respectively determines a plurality of sets for a plurality of combinations of {indexes of DL time slots overlapping with UL time slots, indexes of time slot timing values} (the plurality of combinations of {indexes of DL time slots overlapping with UL time slots, indexes of time slot timing values} correspond one-to-one to the plurality of sets); the combination of {index n D , index k} is any one of the plurality of combinations of {indexes of DL time slots overlapping with UL time slots, indexes of time slot timing values}, and the target set is the set corresponding to the combination of {index n D , index k} among the plurality of sets.

[0366] As an example, for the combination of {index n D , index k}: the first node sets the initial set as the first time domain resource allocation set, and determines that the target set is the initial set or the part of the initial set after removing at least one time domain resource allocation.

[0367] As an example, the target opportunity set includes opportunities for receiving candidate PDSCHs for index n D1 and index k1 and opportunities for receiving candidate PDSCHs for index n D2 and index k2; k1 is less than k2, and the sorting index of the opportunity for receiving the candidate PDSCH for the index n D1 and the index k1 in the target opportunity set is less than the sorting index of the opportunity for receiving the candidate PDSCH for the index n D2 and the index k2 in the target opportunity set.

[0368] As an example, the target opportunity set includes opportunities for receiving candidate PDSCHs for index n D1 and index k1 and opportunities for receiving candidate PDSCHs for index n D2 and index k2; k1 is equal to k2, and n D1 is less than n D2 , and the sorting index of the opportunity for receiving the candidate PDSCH for the index n D1 and the index k1 in the target opportunity set is less than the sorting index of the opportunity for receiving the candidate PDSCH for the index n D2 and the index k2 in the target opportunity set.

[0369] As an embodiment, the index n D1 is the index of a DL time slot overlapping with a UL time slot, and the index n D2 is the index of a DL time slot overlapping with a UL time slot.

[0370] As an embodiment, the index k1 is the index of a time slot timing value in the first set of time slot timing values, and the index k2 is the index of a time slot timing value in the first set of time slot timing values.

[0371] As an embodiment, the first PUCCH is in time slot n U .

[0379] As an embodiment, the benefits of the above method include: being conducive to ensuring the effective transmission of the first type of physical uplink channel occupying symbols indicated as downlink by the uplink / downlink TDD configuration signaling and available for uplink transmission (symbol(s)).

[0380] As an embodiment, the benefits of the above method include: being conducive to applying the solution disclosed in the present application to a full-duplex operation system to improve system efficiency.

[0381] As an example, a symbol that is indicated as a downlink by the uplink and downlink TDD configuration signaling and is available for uplink transmission is indicated as a downlink by the uplink and downlink TDD configuration signaling, and this symbol is available for uplink transmission.

[0382] As an example, the first type of time domain resource is a symbol that is indicated as a downlink by the uplink and downlink TDD configuration signaling and is available for uplink transmission.
