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 existing NR (New Radio) systems, spectrum resources are statically divided into FDD (Frequency Division Duplex) and TDD (Time Division Duplex) spectrum. For TDD spectrum, both base stations and UEs (User Equipment) operate in half-duplex mode. This half-duplex mode avoids self-interference and mitigates the impact of cross-link interference (CLI), but it also leads to decreased resource utilization and increased latency. To address these issues, supporting flexible duplex modes or variable link directions (uplink, downlink, or flexible) on TDD or FDD spectrum has become a possible solution. The 3GPP (3rd Generation Partner Project) has agreed to conduct research on duplex technology (especially subband non-overlapping full duplex (SBFD) mode at the gNB (NR Node B) end); optimizing the system design accordingly is an important part of this research. Summary of the Invention

[0003] HARQ-ACK (Hybrid Automatic Repeat reQuest Acknowledgement) feedback is a crucial component of mobile communication technology, and enhancing HARQ-ACK feedback is a critical issue that needs to be considered in system design. This application discloses a solution to the aforementioned problem. It should be noted that this application is applicable to various wireless communication scenarios, such as scenarios using SBFD mode, scenarios using other types of full-duplex modes besides SBFD, and scenarios using more flexible duplex modes, achieving similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to scenarios using SBFD mode, scenarios using other types of full-duplex modes besides SBFD, and scenarios using more flexible duplex modes) can also help reduce hardware complexity and cost, or improve performance. Unless otherwise specified, embodiments and features in any node of this application can be applied to any other node. Unless otherwise specified, embodiments and features in any node of this application can be arbitrarily combined with each other.

[0004] 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.

[0008] The opportunity set depends on whether the first set is empty, and the first set depends on whether the PDSCH time resource corresponding to the first allocation item in at least one time slot spans different types of symbols. The first allocation item is an allocation item for time-domain resources, and the different types include at least full-duplex and non-full-duplex.

[0025] As an example, to reduce the complexity of UE processing or system design, the base station can avoid using the opportunity to receive candidate PDSCH across different types of symbols to transmit PDSCH. In such a scenario, the scheme disclosed in this application can avoid unnecessary HARQ-ACK information reporting for the aforementioned opportunity to receive candidate PDSCH across different types of symbols, thereby effectively reducing the overhead of HARQ-ACK feedback.

[0077] The technical solution of this application will be further described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0078] Example 1

[0079] Example 1 illustrates a processing flowchart of the first node according to an embodiment of this application, as shown in the attached diagram. Figure 1 As shown.

[0080] In Embodiment 1, the first node in this application receives the first signaling in step 101 and sends the first HARQ-ACK bit block in step 102.

[0081] In Embodiment 1, the transmission of the first HARQ-ACK bit block depends on the first signaling; the first HARQ-ACK bit block includes at least one HARQ-ACK bit for an opportunity set, the opportunity set including opportunities for candidate PDSCH reception; the opportunity set depends on whether a first set is empty, the first set depends on whether the PDSCH time resource corresponding to the first allocation item in at least one time slot spans different types of symbols, the first allocation item is an allocation item for time domain resources, the different types including at least full-duplex and non-full-duplex.

[0082] As an example, the first signaling is physical layer signaling.

[0083] As an example, the first signaling is in DCI (Downlink Control Information) format.

[0084] As an example, the first signaling is higher-layer signaling.

[0085] As one embodiment, the first HARQ-ACK bit block includes one or more HARQ-ACK bits.

[0086] As an example, the first signaling triggers the reporting of at least a portion of the first HARQ-ACK (Hybrid Automatic Repeat reQuest Acknowledgement) bit block.

[0087] As an example, the first signaling triggers a PUCCH (Physical Uplink Control Channel) transmission, which includes the transmission of the first HARQ-ACK bit block.

[0088] As one embodiment, the transmission of the first HARQ-ACK bit block depends on the first signaling, including: the first HARQ-ACK bit block is transmitted in the PUCCH, and the time slot in which the PUCCH is located depends on the first signaling.

[0089] As an example, the first signaling indicates the time slot in which the PUCCH for sending the first HARQ-ACK bit block is located.

[0090] As an example, the PUCCH for sending the first HARQ-ACK bit block is transmitted in uplink time slot n0+k0, where k0 is provided by the PDSCH-to-HARQ_feedbacktiming indicator field in the first signaling, and n0 represents the downlink time slot n used for PDSCH reception. D The last overlapping uplink time slot used for PUCCH transmission, the first signaling scheduling ends in downlink time slot n. D At least one PDSCH.

[0091] As an example, the first HARQ-ACK bit block includes a semi-static HARQ-ACK codebook.

[0092] As an example, the method disclosed in this application is beneficial for optimizing the generation of semi-static HARQ-ACK codebooks.

[0093] As an example, the method disclosed in this application helps to avoid the occurrence of some unnecessary HARQ-ACK bits in the semi-static HARQ-ACK codebook.

[0094] As an example, the first HARQ-ACK bit block includes HARQ-ACK bits (bit(s)) indicating the decoding result of at least one transport block in the PDSCH scheduled by the first signaling.

[0095] As an example, the first HARQ-ACK bit block includes at least one HARQ-ACK bit generated for each opportunity in the opportunity set.

[0096] As an example, for one opportunity in the set of opportunities:

[0097] When a transport block is received during this opportunity, the first HARQ-ACK bit block includes HARQ-ACK bits indicating the decoding result of the transport block in the PDSCH reception; when no transport block is received during this opportunity, the first HARQ-ACK bit block includes NACK generated for this opportunity.

[0098] As an example, the first HARQ-ACK bit block includes HARQ-ACK bits indicating the decoding result of a transport block in one of the opportunities in the opportunity set.

[0099] As an example, whether a transport block is received in one of the opportunities in the opportunity set is determined based on whether the corresponding DCI format is detected.

[0100] As an example, when the first node detects a DCI format for scheduling a transport block in an opportunity within the opportunity set, a transport block is received in that opportunity within the opportunity set; when the first node does not detect a DCI format for scheduling a transport block in an opportunity within the opportunity set, no transport block is received in that opportunity within the opportunity set.

[0101] As an example, one of the opportunities in the set of opportunities is the opportunity for candidate PDSCH reception.

[0102] As an example, one of the opportunities in the set of opportunities is the opportunity for SPS PDSCH release.

[0103] As an example, one of the opportunities in the set of opportunities is the opportunity for a TCI (Transmission Configuration Indicator) state update.

[0104] As one example, the number of opportunities in the opportunity set depends on whether the first set is an empty set.

[0105] As an example, when the first set is an empty set, the opportunity set includes Q1 opportunities; when the first set is not an empty set, the opportunity set includes Q2 opportunities; Q1 and Q2 are both configurable positive integers, and Q1 and Q2 are not equal.

[0106] As an example, Q1 is smaller than Q2.

[0107] As an example, Q2 is a positive integer multiple of Q1.

[0108] As one embodiment, whether the opportunity set includes at least one opportunity for the first time slot timing value and the first time slot depends on whether the first set is an empty set.

[0109] As an example, when the first set of conditions is satisfied, the set of opportunities includes at least one opportunity for the first time slot timing value and the first time slot; when the first set of conditions is not satisfied, the set of opportunities does not include opportunities for the first time slot timing value and the first time slot. The first set of conditions includes: the first set is not an empty set.

[0110] As an example, one allocation item in this application is a row in a time-domain resource allocation table.

[0111] As an example, the first allocation item is used for time-domain resource allocation of PDSCH.

[0112] As an example, the first allocation item is a time-domain resource allocation item, including: the first allocation item at least defines SLIV (Start and Length IndicatorValue).

[0113] As an example, the first allocation item defines at least some of the slot offset, SLIV, and PDSCH mapping type.

[0114] As an example, the first set depends on whether the PDSCH time resource corresponding to the first allocation item in at least one time slot is across different types of symbols, and the at least one time slot depends on the configuration of the transmission repetition number.

[0115] As an example, the different types include only full-duplex and non-full-duplex.

[0116] As an example, the different types also include types other than full-duplex and non-full-duplex.

[0117] As an example, the different types also include types corresponding to symbols used to separate full-duplex symbols and non-full-duplex symbols.

[0118] Example 2

[0119] Example 2 illustrates a schematic diagram of a network architecture according to an embodiment of this application, as shown in the attached diagram. Figure 2 As shown. (Attached) Figure 2This describes the network architecture 200 of a 5G NR (New Radio) / LTE (Long-Term Evolution) / LTE-A (Long-Term Evolution Advanced) system. The 5G NR / LTE / LTE-A network architecture 200 can also be referred to as 5GS (5G System) / EPS (Evolved Packet System) 200, or some other suitable term. 5GS / EPS 200 includes at least one of UE (User Equipment) 201, RAN (Radio Access Network) 202, 5GC (5G Core Network) / EPC (Evolved Packet Core) 210, HSS (Home Subscriber Server) / UDM (Unified Data Management) 220, and Internet services 230. 5GS / EPS can interconnect with other access networks, but these entities / interfaces are not shown for simplicity. As shown in the figure, 5GS / EPS provides packet-switched services; however, those skilled in the art will readily understand that the various concepts presented throughout this application can be extended to networks providing circuit-switched services or other cellular networks. The RAN includes node 203 and other nodes 204. Node 203 provides user and control plane protocol termination to UE 201. Node 203 can be connected to other nodes 204 via an Xn interface (e.g., backhaul) / X2 interface. Node 203 may also be referred to as a base station, base transceiver station, radio base station, radio transceiver, transceiver function, Basic Service Set (BSS), Extended Service Set (ESS), TRP (Transmitter Receiver Point), or some other suitable term.

Node 203 is connected to 5GC / EPC210 via the S1 / NG interface. 5GC / EPC210 includes MME (Mobility Management Entity) / AMF (Authentication Management Field) / SMF (Session Management Function) 211, other MME / AMF / SMF 214, S-GW (Service Gateway) / UPF (User Plane Function) 212, and P-GW (Packet Data Network Gateway) / UPF 213. The MME / AMF / SMF211 is the control node that handles signaling between UE201 and 5GC / EPC210. ​​Essentially, the MME / AMF / SMF211 provides bearer and connection management. All user IP (Internet Protocol) packets are transmitted through the S-GW / UPF212, which is itself connected to the P-GW / UPF213. The P-GW provides UE IP address allocation and other functions. The P-GW / UPF213 is connected to Internet service 230.

[0129] Example 3

[0130] 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 V2X (Vehicle to Everything) RSU, on-board equipment, or on-board communication module) and the second communication node device (gNB, UE, or V2X RSU, on-board equipment, or on-board communication module), or between two UEs, is illustrated using three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second communication node devices and between the two UEs via PHY301. L2305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and supports cross-cell mobility between the second communication node devices and the first communication node device. The RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat Request). The MAC sublayer 302 provides multiplexing between logical and transport channels. It is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in L3 of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second communication node device and the first communication node device.The radio protocol architecture of user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture for the first and second communication node devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355, and MAC sublayer 352 in L2 layer 355. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS (Quality of Service) streams and Data Radio Bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., the IP (Internet Protocol) layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

[0138] Example 4

[0139] 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.

[0140] 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.

[0141] 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.

[0142] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-Quadrature Amplitude Modulation (M-QAM)). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing to generate one or more spatial streams. Transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then uses an inverse fast fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by multi-antenna transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0143] 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.

[0144] 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.

[0145] 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.

[0302] Example 10

[0303] Example 10 illustrates a schematic diagram of a full-duplex symbol and a non-full-duplex symbol according to an embodiment of this application, as shown in the attached diagram. Figure 10 As shown.

[0304] In Example 10, when a symbol is indicated as downlink by uplink / downlink TDD configuration signaling and is available for uplink transmission, the symbol is a full-duplex symbol; when a symbol is indicated as uplink by uplink / downlink TDD configuration signaling, the symbol is a non-full-duplex symbol.

[0305] As an example, one of the symbols in this application is the OFDM (Orthogonal Frequency Division Multiplex) symbol.

[0306] As an example, a symbol in this application is a symbol in a slot.

[0307] As an example, a symbol in this application is a symbol defined in the time domain.

[0308] As an example, a symbol that is indicated as downlink by the uplink / downlink TDD configuration signaling and can be used for uplink transmission is indicated as downlink by the uplink / downlink TDD configuration signaling, and this symbol can be used for uplink transmission.

[0309] As an example, a symbol can be configured as either a full-duplex symbol or a non-full-duplex symbol.

[0310] As an example, the symbol type of a full-duplex symbol is full-duplex.

[0311] As an example, the symbol type of a non-full-duplex symbol is non-full-duplex.

[0312] As an example, when a symbol is indicated as a downlink symbol by uplink / downlink TDD configuration signaling and is available for uplink transmission, the symbol is a full-duplex symbol; when a symbol is indicated as an uplink symbol by uplink / downlink TDD configuration signaling, the symbol is a non-full-duplex symbol.

[0313] As an example, when a symbol is in a time domain resource indicated as downlink by uplink / downlink TDD configuration signaling and is available for uplink transmission, the symbol is a full-duplex symbol; when a symbol is in a time domain resource indicated as uplink by uplink / downlink TDD configuration signaling, the symbol is a non-full-duplex symbol.

[0314] As an example, when a symbol is indicated by uplink / downlink TDD configuration signaling as downlink and available for uplink transmission, the symbol is a full-duplex symbol.

[0315] As an example, a symbol is a full-duplex symbol when it is in a time-domain resource indicated as downlink by uplink / downlink TDD configuration signaling and is available for uplink transmission.

[0316] As an example, the advantages of the above method include: it helps to improve uplink capacity.

[0317] As an example, whether a symbol is a full-duplex symbol or a non-full-duplex symbol depends on the uplink and downlink TDD configuration signaling.

[0318] As an example, there is no symbol that is both a full-duplex symbol and a non-full-duplex symbol.

[0319] As an example, when a symbol is configured to be used for full-duplex operation, the symbol is a full-duplex symbol.

[0320] As an example, when a symbol is not a full-duplex symbol, it is a non-full-duplex symbol.

[0321] As an example, when a symbol is indicated as uplink by uplink / downlink TDD configuration signaling, the symbol is a non-full-duplex symbol.

[0322] As an example, when a symbol is indicated as an uplink time domain resource by uplink / downlink TDD configuration signaling, the symbol is a non-full-duplex symbol.

[0323] As an example, when a symbol is configured to be used for full-duplex operation, the symbol is a full-duplex symbol; when a symbol is configured not to be used for full-duplex operation, the symbol is a non-full-duplex symbol.

[0324] As an example, a symbol is a full-duplex symbol when it is configured to be used for full-duplex operation; a symbol is a non-full-duplex symbol when it is not configured to be used for full-duplex operation.

[0325] As an example, the symbol used for SBFD operation is the full-duplex symbol.

[0326] As an example, the symbol not used for SBFD operations is the non-full-duplex symbol.

[0327] As an example, SBFD symbols are full-duplex symbols, and non-SBFD symbols are non-full-duplex symbols.

[0328] As an example, all symbols in a full-duplex time slot are full-duplex symbols.

[0329] As an example, all symbols in a non-full-duplex time slot are non-full-duplex symbols.

[0330] As an example, the symbols indicated by the Uplink / Downlink TDD configuration signaling as downlink and usable for uplink transmission are full-duplex symbols.

[0331] As an example, the above method is beneficial to improve resource utilization efficiency on symbols that are indicated as downlink by the uplink / downlink TDD configuration signaling and can be used for uplink transmission.

[0332] As an example, whether a flexible symbol is a full-duplex symbol is configurable.

[0333] As an example, whether a flexible symbol is a full-duplex symbol is configured by RRC signaling.

[0334] As an example, there is a flexible symbol that is configured as a full-duplex symbol.

[0335] As an example, a symbol that is indicated as downlink by the uplink / downlink TDD configuration signaling and can be used for uplink transmission is indicated as downlink by the uplink / downlink TDD configuration signaling, and this symbol can be used for uplink transmission.

[0336] As an example, at least one symbol indicated as downlink by the uplink / downlink TDD configuration signaling is not a full-duplex symbol.

[0337] As an example, whether a symbol indicated as downlink by the uplink / downlink TDD configuration signaling is a full-duplex symbol is configurable.

[0338] As an example, whether a symbol indicated as downlink by the uplink / downlink TDD configuration signaling is a full-duplex symbol is configured by the RRC signaling.

[0339] As an example, symbols indicated by the uplink / downlink TDD configuration signaling as downlink and unavailable for uplink transmission are not full-duplex symbols.

[0340] As an example, symbols indicated by the uplink / downlink TDD configuration signaling as downlink and usable for uplink transmission are full-duplex symbols; symbols indicated by the uplink / downlink TDD configuration signaling as downlink and not usable for uplink transmission are non-full-duplex symbols.

[0341] As an example, symbols indicated as uplink by the uplink / downlink TDD configuration signaling cannot be used for downlink transmission.

[0342] As one example, the ability to use for uplink transmission includes: at least the ability to use for PUCCH transmission(s).

[0343] As one embodiment, the ability to use for uplink transmission includes: being able to transmit PUCCH at least in a portion of the frequency band.

[0344] As one embodiment, the uplink transmissions available include at least PUSCH (Physical Uplink Shared Channel) transmissions and PUCCH transmissions.

[0345] As an example, the transmissions available for uplink transmission include at least PUSCH transmission, PUCCH transmission, and SRS transmission.

[0347] As an example, the uplink transmissions available include those available for PUSCH transmission, PUCCH transmission, PRACH (Physical Random Access Channel) transmission, and SRS transmission.

[0348] As an example, the Uplink / Downlink TDD (Time Division Duplex) configuration signaling is signaling indicating the link direction of the symbol.

[0349] As an example, the uplink / downlink TDD configuration signaling indicates at least one symbol as downlink.

[0350] As an example, the uplink / downlink TDD configuration signaling indicates at least one symbol as uplink.

[0351] As an example, the uplink / downlink TDD configuration signaling is RRC signaling.

[0352] As an example, the advantages of the above method include: high reliability of signaling transmission.

[0353] As an example, the uplink and downlink TDD configuration signaling is tdd-UL-DL-ConfigurationCommon.

[0354] As an example, the advantages of the above method include: the uplink and downlink TDD configuration signaling can be applied to multiple users, which helps to reduce control signaling overhead.

[0355] As an example, the uplink and downlink TDD configuration signaling is tdd-UL-DL-ConfigurationDedicated.

[0356] As one example, the uplink and downlink TDD configuration signaling includes tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated.

[0357] As an example, the uplink and downlink TDD configuration signaling includes at least one of tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated.

[0358] As one example, the uplink and downlink TDD configuration signaling includes tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated.

[0359] As an example, when a symbol is indicated as uplink / downlink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, this symbol is the symbol indicated as uplink / downlink by the uplink / downlink TDD configuration signaling.
