Description

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] 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.

[0003] In the new air interface technology, multi-carrier (including carrier aggregation and dual connectivity) technology is an important component. In order to adapt to various application scenarios and meet different needs, 3GPP has been evolving multi-carrier technology since Rel-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 the corresponding carriers or corresponding PDCCHs (Physical Downlink Control Channels), but scheduling is not supported on the same PDCCH on the same carrier.

[0005] In view of the problem that the same PDCCH simultaneously schedules multiple carriers or multiple cells in the multi-carrier system of NR, the present application discloses a solution. It should be noted that in the description of the present application, PDCCH scheduling in multi-carrier is only used as a typical application scenario or example; the present 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, Internet of Vehicles, 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) also helps to reduce hardware complexity and cost.

[0285] Example 3

[0286] Embodiment 3 shows a schematic diagram of an embodiment of a wireless protocol architecture of a user plane and a control plane according to the present application, as shown in the attached Figure 3 shown. 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.).

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 signal of the first information block and the physical layer signal of the first DCI 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)), 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 high-level information included in the first information block in this application.
