Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to multi-carrier transmission schemes and apparatus in wireless communication. Background Technology

[0002] 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 study New Radio (NR) (or 5G). At the 3GPP RAN #75 plenary meeting, the WI (Work Item) for New Radio (NR) was adopted, and the standardization work for NR began.

[0003] In New Radio (NR) technologies, multi-carrier technology (including carrier aggregation and dual connectivity) is an important component. To adapt to diverse application scenarios and meet different needs, 3GPP has been evolving multi-carrier technology since Release 15. Summary of the Invention

[0004] In multi-carrier communication processes, such as carrier aggregation (CA), cross-carrier scheduling is supported. In networks supported by existing standards, such as 5G NR (New Radio) versions R17 and earlier, for multiple scheduled carriers, scheduling is only supported on their respective corresponding carriers or their corresponding PDCCH (Physical Downlink Control Channel), and scheduling through the same PDCCH on the same carrier is not supported.

[0005] To address the issue of simultaneously scheduling PDSCHs or PUSCHs on multiple carriers using the same PDCCH in a multi-carrier NR system, this application discloses a solution. It should be noted that the description in this application uses PDCCH scheduling in a multi-carrier configuration as a typical application scenario or example; this application is also applicable to other scenarios facing similar problems (such as scenarios with higher control channel capacity requirements, including but not limited to capacity enhancement systems, systems using higher frequencies, coverage enhancement systems, unlicensed frequency domain communication, IoT (Internet of Things), URLLC (Ultra-Reliable Low Latency Communication) networks, and vehicle-to-everything (V2X) networks), achieving similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to multi-carrier scenarios) helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in the first node device of this application can be applied to the second node device, and vice versa. In particular, the interpretation of terms, nouns, functions and variables in this application (unless otherwise specified) can be found in the definitions in the 3GPP specification protocols TS36, TS38 and TS37 series.

[0231] Example 3

[0232] 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 node device (UE or gNB) and the second node device (gNB or UE) 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 node devices via PHY301. L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the 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 through encrypted data packets and supports cross-regional mobility between the second node devices and the first node device. 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. 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 among first-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-node devices and the first-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 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 flows and Data Radio Bearers (DRBs) to support service diversity.Although not illustrated, the first node device may have several upper layers above 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., remote UE, server, etc.).

[0235] Example 4

[0236] Example 4 illustrates a schematic diagram of a first node device and a second node device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown.

[0238] The second node device (410) may include a controller / processor 440, a data source / buffer 430, a receiver processor 412, a transmitter / receiver 416 and a transmitter processor 415, wherein the transmitter / receiver 416 includes an antenna 420.

[0239] In the DL (Downlink), upper-layer packets, such as the higher-layer information included in the first information block of this application, are provided to the controller / processor 440. The controller / processor 440 implements functions of Layer 2 and above. In the DL, the controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between logic and transport channels, and radio resource allocation for the first node device 450 based on various priority metrics. The controller / processor 440 is also responsible for HARQ operation, retransmission of lost packets, and signaling to the first node device 450, such as the generation of higher-layer information included in the first information block of this application. The transmit processor 415 implements various signal processing functions for Layer 1 (i.e., physical layer), including coding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation, such as the generation of physical layer signals carrying the first information block of this application and physical layer signals corresponding to multiple PDCCH candidates, which is completed in the transmit processor 415. The generated modulation symbols are divided into parallel streams, and each stream is mapped to a corresponding multicarrier subcarrier and / or multicarrier symbol. These are then transmitted by the transmit processor 415 via the transmitter 416 to the antenna 420 as radio frequency (RF) signals. At the receiver, each receiver 456 receives the RF signal through its corresponding antenna 460. Each receiver 456 recovers the baseband information modulated onto the RF carrier and provides the baseband information to the receive processor 452. The receive processor 452 implements various signal reception processing functions at Layer 1. These functions include monitoring the physical layer signal carrying the first information block of this application and multiple PDCCH candidates; demodulating the multicarrier symbols in the multicarrier symbol stream based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)); subsequently 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 interprets the high-level information included in the first information block of this application.

In the appendix Figure 12 In the first node device processing unit 1200, there are a first transceiver 1201 and a first receiver 1202. The first transceiver 1201 includes the components specified in the appendix of this application. Figure 4 The transmitter / receiver 456 (including antenna 460), receiver processor 452, transmitter processor 455, and controller / processor 490 are included; the first receiver 1202 includes the appendix to this application. Figure 4 The transmitter / receiver 456 (including antenna 460), receiver processor 452, and controller / processor 490 are included.

[0511] As one embodiment, the plurality of PDCCH candidates includes a first PDCCH candidate and a second PDCCH candidate. The first PDCCH candidate is for a first DCI format, and the second PDCCH candidate is for a second DCI format. The size of the first DCI format and the size of the second DCI format are equal.
