[0004] --Title of the invention of the original application: A method and apparatus in a node for wireless communication Technical Field

[0005] The present application relates to a transmission method and device in a wireless communication system, and in particular to a multi-carrier transmission scheme and device in wireless communication. Background Art

[0006] In the future, the application scenarios of wireless communication systems will become more and more diversified, and different application scenarios will put forward different performance requirements for 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 study the new radio (NR) (or 5G), and the WI (Work Item) of the new radio (NR) was passed at the 3GPP RAN #75 plenary meeting, and the standardization work on NR began.

[0007] In the new air interface technology, enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC), and massive machine type communications (mMTC) are three main application scenarios. Multi-carrier (including carrier aggregation and dual connectivity) is an effective technical means to meet the needs of eMBB and URLLC. Summary of the invention

[0008] In multi-carrier communication processes, such as carrier aggregation (CA), cross-carrier scheduling is supported. At the same time, in order to meet the requirements of URLLC, the user equipment can monitor the physical downlink control channel candidate (PDCCH Candidate) based on the span. The combination of carrier aggregation and span-based scheduling can maximize the flexibility of network scheduling and configuration and optimize the performance of the entire system.

[0009] In view of the problem of multi-carrier technology being applied in the URLLC scenario, the present application discloses a solution. It should be noted that in the description of the present application, multi-carrier and URLLC are only used as a typical application scenario or example; the present application is also applicable to other scenarios other than multi-carrier or URLLC facing similar problems (such as other multi-carrier transmission or multi-channel transmission, or other networks with specific requirements for data scheduling), and similar technical effects can also be achieved. In addition, the use of a unified solution for different scenarios (including but not limited to multi-carrier and URLLC scenarios) also helps to reduce hardware complexity and cost. In the absence of conflict, the embodiments and features in the embodiments of the first node device of the present application can be applied to the second node device, and vice versa. In particular, the interpretation of the terms (Terminology), nouns, functions, and variables in the present application (if not otherwise specified) can refer to the definitions in the 3GPP specification protocols TS36 series, TS38 series, and TS37 series.

Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3The radio protocol architecture of the control plane 300 for the first node device (UE or gNB) and the second node device (gNB or UE) is shown with 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. The L1 layer will be referred to as PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first node device and the second node device through PHY301. The 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 node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets, and provides inter-zone mobility support for the first node device between the second node devices. 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. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between first node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in layer 3 (L3 layer) 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 node device and the first node device. The radio protocol architecture of the user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first node device and the second node device in the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355, but the 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 a SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support the diversity of services.Although not shown, the first node device may have several upper layers above the L2 layer 355, including a network layer (e.g., an IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., a remote UE, a server, etc.).

[0321] The first node device (450) may include a controller / processor 490, a data source / buffer 480, a receiving processor 452, a transmitter / receiver 456 and a transmitting processor 455, and the transmitter / receiver 456 includes an antenna 460.

[0322] The second node device ( 410 ) may include a controller / processor 440 , a data source / buffer 430 , a receiving processor 412 , a transmitter / receiver 416 and a transmitting processor 415 , and the transmitter / receiver 416 includes an antenna 420 .

[0323] In DL (Downlink), the upper layer packets, such as the high-layer information included in the first information block, the fourth information block and the fifth information block in the present application, are provided to the controller / processor 440. The controller / processor 440 implements the functions of the L2 layer and above. In DL, the controller / processor 440 provides packet header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and allocation of radio resources to the first node device 450 based on various priority metrics. The controller / processor 440 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first node device 450, such as the high-layer information included in the first information block, the fourth information block and the fifth information block in the present application are all generated in the controller / processor 440. The transmit processor 415 implements various signal processing functions for the L1 layer (i.e., the physical layer), including coding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation, etc. For example, the generation of the physical layer signals of the first information block, the fourth information block, and the fifth information block in the present application is completed in the transmit processor 415. When there is a control channel candidate in the M1 control channel candidate in the present application that is used to transmit the control signaling, the generation of the transmitted control signaling is completed in the transmit processor 415. The generated modulated symbols are divided into parallel streams and each stream is mapped to a corresponding multi-carrier subcarrier and / or multi-carrier symbol, and then mapped to the antenna 420 by the transmit processor 415 via the transmitter 416 and transmitted in the form of a radio frequency signal. At the receiving end, each receiver 456 receives the radio frequency signal through its corresponding antenna 460, and each receiver 456 recovers the baseband information modulated on the radio frequency carrier and provides the baseband information to the receive processor 452. The receive processor 452 implements various signal reception processing functions of the L1 layer. The signal reception processing function includes receiving the physical layer signals of the first information block, the fourth information block and the fifth information block in the present application and monitoring the M1 control channel alternatives in the present application, demodulating the multi-carrier symbols in the multi-carrier symbol stream based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK)), and then descrambling, decoding and deinterleaving to recover the data or control transmitted by the second node device 410 on the physical channel, and then providing the data and control signals to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and above, and the controller / processor 490 interprets the first information block, the fourth information block and the fifth information block in the present application. The controller / processor may be associated with a memory 480 that stores program codes and data. The memory 480 may be referred to as a computer-readable medium.

[0324] In uplink (UL) transmission, the data source / buffer 480 is used to provide high-layer data to the controller / processor 490. The data source / buffer 480 represents the L2 layer and all protocol layers above the L2 layer. The controller / processor 490 implements the L2 layer protocol for the user plane and the control plane by providing header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the second node 410. The controller / processor 490 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the second node 410. The second information block and the third information block in this application are generated at the controller / processor 490. The transmission processor 455 implements various signal transmission processing functions for the L1 layer (i.e., the physical layer), and the physical layer signal carrying the second information block and the third information block is generated at the transmission processor 455. The signal transmission processing function includes sequence generation (for signals generated by sequences), encoding and interleaving to facilitate forward error correction (FEC) at UE450, and modulation of baseband signals based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK)) (for signals generated by bit blocks), dividing the sequence-generated signals or modulation symbols into parallel streams and mapping each stream to a corresponding multi-carrier subcarrier and / or multi-carrier symbol, and then mapping to antenna 460 via transmitter 456 by the transmit processor 455 to transmit in the form of RF signals. The receiver 416 receives the RF signal through its corresponding antenna 420, and each receiver 416 recovers the baseband information modulated onto the RF carrier and provides the baseband information to the receive processor 412. The receiving processor 412 implements various signal receiving and processing functions for the L1 layer (i.e., the physical layer), including receiving and processing the physical layer signal carrying the second information block and the third information block in the present application, and the signal receiving and processing function includes acquiring a multi-carrier symbol stream, then performing sequence decorrelation or demodulation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK)) on the multi-carrier symbols in the multi-carrier symbol stream, and then decoding and deinterleaving to recover the data and / or control signal originally transmitted by the first node device 450 on the physical channel. The data and / or control signal is then provided to the controller / processor 440. The functions of the L2 layer are implemented in the controller / processor 440, including reading the second information block and the third information block in the present application. The controller / processor may be associated with a buffer 430 storing program code and data. The buffer 430 may be a computer-readable medium.
