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. At the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) 1#103e meeting, research on duplex technology was approved, particularly the proposal of Sub-Band Non-Overlapping Full Duplex (SBFD) mode at the gNB (NR Node B) level. In this mode, the same symbol is used for uplink in some frequency resources and downlink in others, thus improving resource utilization and reducing latency. Summary of the Invention

[0003] In scenarios where symbols are configured as downlink symbols indicated by uplink and downlink TDD configuration signaling and can be used for uplink transmission, how to transmit signals based on DCI (Downlink Control Information) indications is a key problem that must be solved; this application discloses a solution to the above problem. It should be noted that this application is applicable to various wireless communication scenarios, such as scenarios using SBFD mode, scenarios using other types of full-duplex modes besides SBFD, scenarios using more flexible duplex modes, and scenarios supporting only half-duplex mode, achieving similar technical effects. Furthermore, using 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, scenarios using more flexible duplex modes, and scenarios supporting only half-duplex mode) can also help reduce hardware complexity and cost, or improve performance. Without conflict, the embodiments and features in any node of this application can be applied to any other node. Without conflict, the embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

[0242] Example 3

[0243] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for the control plane 300 between the first communication node device (UE, gNB, or RSU in V2X) and the second communication node device (gNB, UE, or RSU in V2X), or between two UEs, is illustrated using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second communication node devices and between the two UEs via PHY301. L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and supports cross-cell mobility between second communication node devices and the first communication node device. RLC sublayer 303 provides upper layer data packet segmentation and reassembly, retransmission of lost data packets, and data packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell between the first communication node devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second and first communication node devices. The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first and second communication node devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for physical layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355 and MAC sublayer 352 in L2 layer 355. However, PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS streams and data radio bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

[0250] Example 4

[0251] 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 the access network.

[0252] 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.

[0253] 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.

[0254] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0255] 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.

[0256] 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.

[0257] 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.

[0298] Example 6

[0299] Example 6 illustrates a schematic diagram of the relationship between the content indicated by the first field in the first DCI according to an embodiment of this application and the signals included in the first signal set, as shown in the attached diagram. Figure 6 As shown.

[0300] In Embodiment 6, when the first signal set includes only the first type of signal, or when the first signal set includes only the second type of signal: the content indicated by the first field in the first DCI includes a value that each signal in the first signal set depends on.

[0301] As an example, when the first signal set includes only the first type of signal, or when the first signal set includes only the second type of signal: the content indicated by the first field in the first DCI includes only one value, and each signal in the first signal set depends on this value.

[0302] As an example, the features of the above method include: when all signals in the first signal set are signals of the same type, each signal in the first signal set depends on only one value included in the content indicated by the first field in the first DCI; the above method has good compatibility with existing protocols.

[0303] As an example, the first signal set including only the first type of signal means that each signal in the first signal set is a signal of the first type.

[0304] As an example, the meaning of "the first signal set includes only the second type of signals" is that each signal in the first signal set is a second type of signal.

[0305] As an example, the statement that each signal in the first signal set depends on this value includes: the transmission power of each signal in the first signal set depends on this value.

[0306] As an example, the statement that each signal in the first signal set depends on this value includes: in determining the transmission power of each signal in the first signal set, the first node uses this value as a power adjustment value related to closed-loop power control.

[0307] As an example, the statement that each signal in the first set of signals depends on this value includes: the precoding used by each signal in the first set of signals depends on the first value.

[0308] As an example, the statement that each signal in the first signal set depends on this value includes: the precoding used for each signal in the first signal set is determined based on this value.

[0309] As an example, the statement that each signal in the first signal set depends on this value includes: the precoding used by each signal in the first signal set is determined based on at least one SRS resource to which this value is mapped.

[0310] As an example, the statement that each signal in the first signal set depends on this value includes: the precoding used by each signal in the first signal set is determined based on the precoding configuration mapped to this value.

[0311] As an example, a value included in the content indicated by the first field in the first DCI is mapped to at least one SRS (Sounding Reference Signal) resource.

[0312] As an example, a value included in the content indicated by the first field in the first DCI is mapped to a pre-encoded configuration.

[0313] Example 7

[0314] Example 7 illustrates a schematic diagram of the relationship between the content indicated by the first field in the first DCI according to an embodiment of this application and the signals included in the first signal set, as shown in the attached diagram. Figure 7 As shown.

[0315] In embodiment 7, when the first signal set includes a first type signal and a second type signal, the transmission power of the first type signal in the first signal set depends on the first value, and the transmission power of the second type signal in the first signal set depends on the second value; when the first signal set includes only the first type signal, or the first signal set includes only the second type signal: the content indicated by the first field in the first DCI includes a value, and the transmission power of each signal in the first signal set depends on the value.

[0316] As an example, the first domain is the TPC command domain.

[0317] As an example, the first field is a field that indicates power adjustments related to closed-loop power control.

[0318] As an example, when the first signal set includes a first type signal and a second type signal, the transmission power of each first type signal in the first signal set depends on the first value, and the transmission power of each second type signal in the first signal set depends on the second value.

[0319] As an example, when the first signal set includes a first type signal and a second type signal, in determining the transmission power of each first type signal in the first signal set, the first node uses the first value as the power adjustment value related to closed-loop power control, and in determining the transmission power of each second type signal in the first signal set, the first node uses the second value as the power adjustment value related to closed-loop power control.

[0320] As an example, when the first signal set includes only the first type of signal, or when the first signal set includes only the second type of signal: the content indicated by the first field in the first DCI includes a value, which the first node uses as the power adjustment value related to closed-loop power control in determining the transmission power of each signal in the first signal set.

[0324] As an example, when the first signal set includes a first type signal and a second type signal, the precoding used for each first type signal in the first signal set is determined based on the first value, and the precoding used for each second type signal in the first signal set is determined based on the second value; when the first signal set includes only the first type signal, or the first signal set includes only the second type signal: the content indicated by the first field in the first DCI includes a value, and the precoding used for each signal in the first signal set is determined based on the value.

[0325] As an example, when the first signal set includes a first type signal and a second type signal, the precoding used for each first type signal in the first signal set is determined based on at least one SRS resource to which the first value is mapped, and the precoding used for each second type signal in the first signal set is determined based on at least one SRS resource to which the second value is mapped; when the first signal set includes only the first type signal, or the first signal set includes only the second type signal: the content indicated by the first field in the first DCI includes a value, and the precoding used for each signal in the first signal set is determined based on at least one SRS resource to which the value is mapped.

[0326] As an example, it is configurable which SRS resources a value included in the content indicated by the first field in the first DCI is mapped to.

[0327] As an example, when the first signal set includes a first type signal and a second type signal, the precoding used for each first type signal in the first signal set is determined based on the precoding configuration mapped to the first value, and the precoding used for each second type signal in the first signal set is determined based on the precoding configuration mapped to the second value; when the first signal set includes only the first type signal, or the first signal set includes only the second type signal: the content indicated by the first field in the first DCI includes a value, and the precoding used for each signal in the first signal set is determined based on the precoding configuration mapped to the value.

[0328] As an example, it is configurable which precoding configuration a value included in the content indicated by the first field in the first DCI is mapped to.

[0329] As an example, the first domain is an SRI domain.

[0330] As an example, the first field is a field that indicates precoded information.

[0334] As an example, the first type of time-domain resource is a symbol that is indicated as a downlink symbol by uplink / downlink TDD configuration signaling and can be used for uplink transmission.

[0335] As an example, the first type of time-domain resources does not include symbols indicated as uplink symbols by the uplink / downlink TDD configuration signaling.

[0336] As an example, at least one symbol indicated by uplink / downlink TDD configuration signaling as a downlink symbol does not belong to the first type of time domain resource.

[0337] As an example, the first signal in this application may occupy, in the time domain, a symbol that is indicated as a downlink symbol by the uplink / downlink TDD configuration signaling and can be used for uplink transmission.

[0338] As an example, whether a symbol indicated as a downlink symbol by the uplink / downlink TDD configuration signaling can be used for uplink transmission is configurable.

[0339] As an example, whether a symbol indicated as a downlink symbol by the uplink / downlink TDD configuration signaling can be used for uplink transmission is configured by the RRC signaling.

[0340] As an example, whether a flexible symbol belongs to the first type of time-domain resource is configurable.

[0341] As an example, whether a flexible symbol belongs to the first type of time-domain resource is configured by RRC signaling.

[0348] As an example, the statement "can be used for uplink transmission" means that it can be used for at least one of PUSCH transmission, PUCCH transmission, PRACH (Physical Random Access Channel) transmission, and SRS transmission.

[0349] As an example, the statement "can be used for uplink transmission" means that it can be used for at least two of PUSCH transmission, PUCCH transmission, PRACH transmission, and SRS transmission.

[0350] As an example, the statement "can be used for uplink transmission" means that it can be used for at least three of PUSCH transmission, PUCCH transmission, PRACH transmission, and SRS transmission.

[0351] As an example, the statement "can be used for uplink transmission" means that it can be used for PUSCH transmission, PUCCH transmission, PRACH transmission and SRS transmission.

[0352] As an example, the statement "can be used for uplink transmission" means that it can be used for transmission of UL-SCH (Uplink Shared Channel(s)).

[0353] As an example, the Uplink / Downlink TDD (Time Division Duplex) configuration signaling is signaling indicating the link direction of the symbol.

[0354] As an example, the uplink / downlink TDD configuration signaling indicates at least one symbol as a downlink symbol.

[0355] As an example, the uplink / downlink TDD configuration signaling indicates at least one symbol as an uplink symbol.

[0356] As an example, the uplink / downlink TDD configuration signaling is RRC signaling.

[0357] As an example, the advantages of the above method include: high transmission reliability of the uplink and downlink TDD configuration signaling.

[0358] As an example, the uplink and downlink TDD configuration signaling is tdd-UL-DL-ConfigurationCommon.

[0359] As an example, the uplink and downlink TDD configuration signaling is tdd-UL-DL-ConfigurationDedicated.

[0360] As an example, the uplink and downlink TDD configuration signaling is tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated.

[0361] As an example, the uplink and downlink TDD configuration signaling includes tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated.

[0362] As an example, the advantages of the above method include: it facilitates the optimization of transmission resource allocation when at least one of tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated is configured.
