Description

TECHNICAL FIELD

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, in particular to a transmission method and apparatus of a wireless signal in a wireless communication system supporting a cellular network. BACKGROUND

[0002] In the existing NR (New Radio) system, the spectrum resources are statically divided into FDD (Frequency Division Duplex) spectrum and TDD (Time Division Duplex) spectrum. FDD has low spectrum utilization when the uplink and downlink traffic is asymmetric. TDD can transmit and receive through different time slots on the same spectrum, and the uplink and downlink transmission cannot be performed at the same time, and a conversion interval is needed between the uplink and downlink. TDD does not require symmetric spectrum resources, and can flexibly set the uplink and downlink resource ratio to adapt to asymmetric service requirements, but the uplink and downlink conversion will bring additional transmission waiting delay, and the discontinuity of uplink resources in the time domain will also cause the uplink coverage to be limited. Using full duplex technology to simultaneously transmit and receive in the same frequency band can have the advantages of FDD and TDD, and the spectrum efficiency can theoretically be doubled, but it will introduce additional self-interference (i.e. interference of the device's own transmitted signal to the device's own received signal).

[0257] Example 3

[0258] Embodiment 3 shows a diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as described in Figure 3 Figure 3 is a diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3 ​The radio protocol architecture of the control plane 300 between a first communication node device (UE, gNB or RSU (Road Side Unit) in V2X (Vehicle to Everything), a vehicle mounted device or a vehicle mounted communication module) and a second communication node device (gNB, UE or RSU in V2X, a vehicle mounted device or a vehicle mounted communication module), or between two UEs is shown with 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 as PHY 301 in this document. Layer 2 (L2 layer) 305 is on top of PHY 301 and is responsible for the link between the first communication node device and the second communication node device and between two UEs through PHY 301. L2 305 includes a MAC (Medium Access Control) sublayer 302, a 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. The PDCP sublayer 304 also provides security by ciphering the data packets as well as providing header compression, and supports mobility of the first communication node device between cells. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat Qequest). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating the various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in L3 in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers 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.).

[0265] Example 4

[0266] 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.

[0267] 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.

[0268] 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.

[0269] 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.

[0270] 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.

[0271] 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.

[0272] 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.

[0350] Example 7 illustrates a schematic diagram of the frequency domain spacing between a first resource and a second resource according to an embodiment of this application, as shown in the attached diagram. Figure 7 As shown. In the appendix Figure 7 In the diagram, a blank box represents the first resource, and a gray-filled box represents the second resource.

[0351] In Example 7, the first resource and the second resource overlap in the time domain but not in the frequency domain.

[0352] As an example, from the frequency domain perspective, the highest frequency in the first resource is lower than the lowest frequency in the second resource.

[0353] Example 8

[0354] Example 8 illustrates a schematic diagram of a first resource and a second resource according to an embodiment of this application, as shown in the attached diagram. Figure 8 As shown. In the appendix Figure 8 In the diagram, a blank box represents the first resource, and a gray-filled box represents the second resource.

[0355] In Example 8, the first resource and the second resource overlap in both the time domain and the frequency domain; this situation is considered to be when the frequency domain interval between the first resource and the second resource is less than the first threshold.

[0356] Example 9

[0357] Example 9 illustrates a schematic diagram illustrating whether the first and second operations according to an embodiment of this application are executed simultaneously, depending on the relationship between the frequency domain interval between the first and second resources and the first threshold, as shown in the attached diagram. Figure 9 As shown.

[0358] In embodiment 9, when the first set of conditions is satisfied, the first operation and the second operation are executed simultaneously; when the first set of conditions is not satisfied, one of the first operation and the second operation is not executed; the first set of conditions includes: the frequency domain interval between the first resource and the second resource is not less than the first threshold.

[0359] As a sub-implementation of Embodiment 9, when the first set of conditions is not satisfied, the first operation is not executed, and the second operation is executed.

[0360] As a sub-implementation of Embodiment 9, when the first set of conditions is not satisfied, the second operation is not executed, and the first operation is executed.

[0361] As a sub-implementation of Embodiment 9, when the first set of conditions is not met, whether the first operation or the second operation is not executed depends on the priority of the first operation and the second operation.

[0362] As an example, when the first set of conditions is satisfied, the first operation and the second operation are executed simultaneously; when the first set of conditions is not satisfied, one of the first operation and the second operation is not executed; the first set of conditions includes: the frequency domain interval between the first resource and the second resource is greater than the first threshold.

[0363] As a sub-implementation of the above embodiments, the first operation is not executed when the first set of conditions is not satisfied.

[0364] As a sub-implementation of the above embodiments, the second operation is not executed when the first set of conditions is not met.

[0365] As a sub-implementation of the above embodiments, when the first set of conditions is not satisfied, whether the first operation or the second operation is not executed depends on the priority of the first operation and the second operation.

[0366] As an example, the first set of conditions includes only the condition that the frequency domain interval between the first resource and the second resource is not less than the first threshold.

[0367] As an example, the first set of conditions includes multiple conditions; the frequency domain interval between the first resource and the second resource is not less than the first threshold, which is one of the conditions in the first set of conditions.

[0368] As an example, the first set of conditions includes multiple conditions; the first set of conditions being satisfied means that each condition in the first set of conditions is satisfied; the first set of conditions not being satisfied means that at least one condition in the first set of conditions is not satisfied.

[0369] As an example, the first set of conditions also includes that the first node has received an indication to enable simultaneous uplink transmission and downlink reception.

[0370] As an example, the first set of conditions further includes: the first node has received an indication to enable simultaneous uplink transmission and downlink reception, and has not subsequently received an indication to disable simultaneous uplink transmission and downlink reception.

[0371] As an example, the first set of conditions further includes: the sum of the number of frequency domain units included in the first resource in the frequency domain and the number of frequency domain units included in the second resource in the frequency domain does not exceed a second threshold, where the second threshold is a positive integer greater than 1 reported by the first node.

[0372] As an example, the advantages of the above method include reducing the complexity of full-duplex processing for user equipment by limiting the total amount of frequency domain resources occupied by uplink and downlink transmissions in the frequency domain.

[0373] As an example, the first condition set further includes: the difference between the total number of REs included in the first resource and the total number of REs included in the second resource is not less than a second threshold, where the second threshold is a positive integer greater than 1 reported by the first node.

[0374] As an example, the first condition set further includes: the proportion of the number of REs in the first resource that have time domain overlap with the second resource to the total number of REs in the first resource does not exceed a second threshold, where the second threshold is a positive number less than 1 reported by the first node.

[0375] Example 10

[0376] Example 10 illustrates a schematic diagram of an embodiment of the present application in which one of the first and second operations is not performed, as shown in the attached diagram. Figure 10 As shown.

[0377] In embodiment 10, one of the first operation and the second operation is not executed, and which of the first operation and the second operation is not executed depends on the priority of the first operation and the second operation.

[0378] As an example, one of the first operation and the second operation is not executed; the priority of the first operation is different from the priority of the second operation, the one with higher priority among the first operation and the one with lower priority among the first operation and the second operation is not executed.

[0379] As an example, one of the first operation and the second operation is not executed; when the priority of the first operation is different from the priority of the second operation, the one with higher priority is executed and the one with lower priority is not executed; when the priority of the first operation is the same as the priority of the second operation, which one of the first operation and the second operation is not executed is determined according to the signaling instruction.

[0380] As an example, one of the first operation and the second operation is not executed; when the priority of the first operation is different from the priority of the second operation, the one with higher priority is executed and the one with lower priority is not executed; when the priority of the first operation is the same as the priority of the second operation, the first node determines which of the first operation and the second operation is executed and which is not executed.

[0381] As an example, in the above method, when the priority of the first operation is the same as the priority of the second operation, the first node determines which of the first operation and the second operation will be executed and which will not be executed; this feature improves the processing flexibility of the user equipment.

[0382] As an example, when the first resource is allocated for signal transmission of a first priority, the second resource is allocated for signal transmission of a second priority, and the first priority is higher than the second priority: the priority of the first operation is higher than the priority of the second operation.

[0383] As an example, when the first resource is allocated for signal transmission of a first priority, the second resource is allocated for signal transmission of a second priority, and the first priority is lower than the second priority: the priority of the first operation is lower than the priority of the second operation.

[0384] As an example, when both the first resource and the second resource are allocated for signal transmission of the same priority, the priority of the first operation is the same as the priority of the second operation.

[0385] As an example, the priority for a single signal transmission is configurable.

[0386] As an example, the priority of a single signal transmission is indicated by the corresponding scheduling signaling.

[0387] As an example, the priority order of different types of information transmission can be predefined.

[0388] As an example, the transmission of control information has a higher priority than the transmission of data.

[0405] Whether the first operation and the second operation are executed simultaneously depends on the relationship between the frequency domain interval between the first resource and the second resource and the first threshold, where the first threshold is configured, predefined, or depends on the capabilities of the user equipment.

[0406] As an example, when the frequency domain interval between the first resource and the second resource is less than the first threshold, one of the first operation and the second operation is not performed.
