Description

A method and device in a node for wireless communication Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly to a multi-carrier or multi-cell transmission scheme and apparatus in wireless communication. Background Art

[0002] The application scenarios of future wireless communication systems are becoming increasingly diverse, and different scenarios place varying performance requirements on the systems. To meet these diverse performance demands, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) plenary meeting #72 decided to conduct research on New Radio (NR) (or 5G). The 3GPP RAN plenary meeting #75 approved the WI (Work Item) for New Radio, initiating standardization work on NR.

[0003] Multi-carrier technology (including carrier aggregation and dual connectivity) is a key component of the new air interface (NR). To adapt to diverse application scenarios and meet different requirements, 3GPP has been evolving multi-carrier technology since Rel-15.

[0004] Summary of the Invention

[0005] Cross-carrier scheduling is supported in multi-carrier communication processes, such as carrier aggregation (CA). In networks supported by existing standards, such as 5G New Radio (NR) versions R17 and earlier, scheduling of multiple scheduled carriers is only supported on the corresponding carriers or corresponding PDCCHs (Physical Downlink Control Channels), and scheduling through the same PDCCH on the same carrier is not supported.

[0006] In response to the problem of simultaneously scheduling multiple carriers or multiple cells with the same PDCCH in the multi-carrier system of NR, the present application discloses a solution. It should be noted that in the description of this application, PDCCH scheduling in multi-carrier is only used as a typical application scenario or example; this application is also applicable to other scenarios facing similar problems (such as other scenarios with higher requirements for control channel capacity, including but not limited to capacity enhancement systems, systems using higher frequencies, coverage enhancement systems, power saving modes, unlicensed frequency domain communications, IoT (Internet of Things), URLLC (Ultra Reliable Low Latency Communication) networks, vehicle networks, etc.), 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 scenarios) can also help reduce hardware complexity and cost. In the absence of 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 terminology, nouns, functions, and variables in this application (unless otherwise specified) can refer to the definitions in the 3GPP specification protocols TS36 series, TS38 series, and TS37 series.

[0270] Example 3

[0271] Embodiment 3 illustrates a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in FIG3 . FIG3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. FIG3 illustrates the radio protocol architecture of the control plane 300 for a first node device (UE or gNB) and a second node device (gNB or UE) 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. The L1 layer will be referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the first node device and the second node device via PHY 301. 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. These sublayers 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 support for inter-zone mobility of 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 the 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 an SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for mapping between QoS flows and data radio bearers (DRBs) to support service diversity. 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.).

[0272] As an embodiment, the wireless protocol architecture in FIG3 is applicable to the first node device in this application.

[0273] As an embodiment, the wireless protocol architecture in FIG3 is applicable to the second node device in this application.

[0274] As an embodiment, the first DCI in the present application is generated by MAC302, or MAC352, or the PHY301, or PHY351.

[0275] As an embodiment, the first information block in the present application is generated in the RRC306, or MAC302, or MAC352, or the PHY301, or PHY351.

[0276] Example 4

[0279] 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 , wherein the transmitter / receiver 416 includes an antenna 420 .

[0280] In the DL (downlink), upper layer packets, such as the high-layer information included in the first information block in this application, are provided to the controller / processor 440. The controller / processor 440 implements functions for the L2 layer and above. In the DL, the controller / processor 440 provides packet header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation 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. For example, the high-layer information included in the first information block in this application is 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. For example, the physical layer signal for the first information block in this application and the physical layer signal corresponding to the first DCI are generated by 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. The symbols are then mapped by the transmit processor 415 to the antenna 420 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 via its corresponding antenna 460, recovers the baseband information modulated onto the radio frequency carrier, and provides the baseband information to the receive processor 452. The receive processor 452 implements various L1 layer signal reception processing functions. These signal reception processing functions include receiving the physical layer signal of the first information block and the physical layer signal of the first DCI in this application, demodulating the multi-carrier symbols in the multi-carrier symbol stream based on various modulation schemes (e.g., binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK)), and then descrambling, decoding, and deinterleaving to recover the data or control signals transmitted by the second node device 410 on the physical channel. The data and control signals are then provided to the controller / processor 490. Controller / processor 490 is responsible for L2 and above layers. Controller / processor 490 interprets the high-level information included in the first information block in this application. Controller / processor 490 may be associated with memory 480, which stores program codes and data. Memory 480 may be referred to as a computer-readable medium.
