A first time window includes Q first-type time-domain resource blocks, where Q is a positive integer greater than 1. A first symbol is a multi-carrier symbol among the positive integer number of multi-carrier symbols included in any of the Q first-type time-domain resource blocks. The first time unit format is used to indicate whether the first symbol is a first-type symbol. The second information is used to indicate a positive integer number of first-type time-domain resource blocks from a subset of the first time-domain resource blocks. The first time unit format and the second information are jointly used to determine the first resource pool.

Description

[0001] This application is a divisional application of the following original application:

[0002] --The original application was filed on July 8, 2019.

[0003] --Original application number: 201910610969.3

[0004] --Original application title: A method and apparatus used in a node for wireless communication Technical Field

[0005] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus related to sidelinks in wireless communication. Background Technology

[0006] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. In order to meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to conduct research on New Radio (NR) (or Fifth Generation, 5G). The 3GPP RAN #75 plenary meeting adopted the NR WI (Work Item), and began the standardization work of NR.

[0007] In response to the rapidly developing Vehicle-to-Everything (V2X) services, 3GPP has initiated standards development and research within the NR framework. Currently, 3GPP has completed the requirements development for 5G V2X services, which are incorporated into standard TS22.886. 3GPP has identified and defined four major use case groups for 5G V2X services: Vehicles Platnooning, Extended Sensors, Advanced Driving (semi / fully automated driving), and Remote Driving. Research on NR-based V2X technology was initiated at the 3GPP RAN#80 plenary meeting, and at the first AdHoc meeting of RAN12019, it was agreed that the path loss between the transmitter and receiver in V2X would be used as a reference for V2X transmit power. Summary of the Invention

[0008] In traditional LTE / LTE-Advanced systems, several subframe transmission formats exist, with a relatively fixed uplink / downlink ratio for each subframe. However, in NR systems, the uplink / downlink ratio for each time slot is more flexible, even introducing flexible symbols that can be used for either uplink or downlink. But for short-range communication like V2X, uplink resources are generally used; this overly flexible uplink / downlink ratio means that some resources, even with uplink symbols, are unsuitable for V2X communication.

[0009] To address the aforementioned issues, this application discloses a secondary link resource pool configuration scheme, effectively solving the problem of efficient utilization of flexible time slot formats in V2X systems. It should be noted that, without conflict, the embodiments and features in the user equipment of this application can be applied to the base station, and vice versa. Without conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other. Furthermore, although this application is initially intended for single-carrier communication, it can also be used for multi-carrier communication. Furthermore, although this application is initially intended for single-antenna communication, it can also be used for multi-antenna communication.

[0236] Example 3

[0237] 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.).

[0248] Example 4

[0249] 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 4This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0250] 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.

[0251] 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.

[0252] 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.

[0253] 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.

[0254] 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.

[0255] 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.

[0709] Example 12 illustrates a flowchart of determining whether a first candidate temporal resource block belongs to a first resource pool according to an embodiment of this application, as shown in the attached diagram. Figure 12 As shown.

[0710] In Example 12, in step S1201, it is determined whether the first candidate time-domain resource block belongs to the first time-domain resource subset; when the result of determining whether the first candidate time-domain resource block belongs to the first time-domain resource subset is "yes", step S1202 is executed to determine whether the first bit is the first value; when the result of determining whether the first bit is the first value is "yes", step S1203 is executed to determine that the first candidate time-domain resource block belongs to the first resource pool; when the result of determining whether the first candidate time-domain resource block belongs to the first time-domain resource subset is "no", step S1204 is executed to determine that the first candidate time-domain resource block does not belong to the first resource pool; when the result of determining whether the first bit is the first value is "no", step S1204 is executed to determine that the first candidate time-domain resource block does not belong to the first resource pool.

[0711] As an example, the first candidate time-domain resource block belonging to the first resource pool means that the first candidate time-domain resource block is one of the Q3 first-class time-domain resource blocks included in the first resource pool in the time domain.

[0712] As an example, the first candidate time-domain resource block not belonging to the first resource pool means that the first candidate time-domain resource block is not any of the Q3 first-class time-domain resource blocks included in the first resource pool in the time domain.

[0713] As one embodiment, the second information includes the first bitmap, which includes B bits, where B is a positive integer.

[0714] As an example, the B bits in the first bitmap correspond to the Q1 first-type time-domain resource blocks in the first time-domain resource block subset.

[0715] As an example, any one of the B bits included in the first bitmap corresponds to at least one first type of time-domain resource block in the first time-domain resource block subset.

[0716] As an example, the B bits in the first bitmap correspond one-to-one with the Q1 first-type time-domain resource blocks in the first time-domain resource block subset, and Q1 is equal to B.

[0721] As an example, when the value of the first bit is a first value, the first target time-domain resource block belongs to the first resource pool.

[0722] As an example, when the value of the first bit is the second value, the first target time-domain resource block does not belong to the first resource pool.

[0723] As an example, the first target time-domain resource block belonging to the first resource pool means that the first target time-domain resource block is one of the Q3 first-class time-domain resource blocks included in the first resource block in the time domain.

[0724] As an example, the first target time-domain resource block not belonging to the first resource pool means that the first target time-domain resource block is not any of the Q3 first-class time-domain resource blocks included in the time domain of the first resource block.

The first target time-domain resource block group includes a positive integer number of first-class time-domain resource blocks.

[0726] As an example, when the value of the first bit is a first value, any first type of time-domain resource block in the first target time-domain resource block group belongs to the first resource pool.

[0727] As an example, when the value of the first bit is the second value, any first type of time-domain resource block in the first target time-domain resource block group does not belong to the first resource pool.

[0728] As an example, any first type of time-domain resource block in the first target time-domain resource block group belonging to the first resource pool means that any first type of time-domain resource block in the first target time-domain resource block group is one of the Q3 first type of time-domain resource blocks included in the first resource block in the time domain.

[0729] As an example, the statement that any first type of time-domain resource block in the first target time-domain resource block group does not belong to the first resource pool means that any first type of time-domain resource block in the first target time-domain resource block group is not any of the Q3 first type of time-domain resource blocks included in the time domain by the first resource block.

[0730] As an example, the first value is 1 and the second value is 0.

[0731] As an example, the first value is 1 and the second value is -1.

[0732] As an example, the first value is the Boolean value "TRUE".

[0737] As an example, the second candidate time-domain resource block belonging to the first resource pool means that the second candidate time-domain resource block is one of the Q3 first-class time-domain resource blocks included in the first resource pool in the time domain.

[0738] As an example, the second candidate time-domain resource block not belonging to the first resource pool means that the first candidate time-domain resource block is not any of the Q3 first-class time-domain resource blocks included in the first resource pool in the time domain.
