Description

Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular to a transmission scheme and apparatus for a control channel 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] The coexistence and smooth evolution between new air interface technologies and other air interface technologies (such as LTE) are of great value to spectrum sharing and commercial deployment. Therefore, 3GPP has been committed to ensuring effective coexistence and smooth transition between new air interface technologies and other air interface technologies during the evolution of new air interface technologies. Summary of the Invention

[0004] In the NR system, the capacity of the control channel often becomes the bottleneck of the capacity of the entire system. In response to the transmission problem of the control channel in NR, the present application discloses a solution. It should be noted that in the description of this application, the coexistence or spectrum sharing of the new air interface technology and other air interface technologies is used as a typical application scenario or example; this application is also applicable to other scenarios facing similar problems (such as scenarios with higher requirements for the robustness or capacity of the control channel, or scenarios where there is a collision between the control channel and other channels or signals using the same air interface technology, including but not limited to capacity enhancement systems, IoT (Internet of Things), URLLC (Ultra Reliable Low Latency Communication) networks, vehicle networks, etc.), and similar technical effects can be achieved. In addition, the use of a unified solution for different scenarios (including but not limited to spectrum sharing 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.

[0305] Example 3

[0306] Example 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. 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 a first node device (UE or gNB) and a second node device (gNB or UE) is shown 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 sits above PHY 301 and is responsible for the link between the first and second node devices via PHY 301. 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 by encrypting data packets and supports handover 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 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) and Layer 2 (L2). The radio protocol architecture for the first and second node devices in the user plane 350 is substantially identical to the corresponding layers and sublayers in the control plane 300, including 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. However, the PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also includes the SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping QoS flows to 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) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., a remote UE, a server, etc.).

[0314] Example 4

[0315] Example 4 shows a schematic diagram of a first node device and a second node device according to an embodiment of the present application, as shown in the attached figure. Figure 4 shown.

[0316] 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.

[0317] 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 .

[0318] In the DL (Downlink), upper layer packets, such as the high-layer information included in the first information block, the second information block, and the fourth information block in this application, are provided to the controller / processor 440. The controller / processor 440 implements the functions of 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 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. For example, the high-layer information included in the first information block, the second information block, and the fourth information block in this application are all generated in the controller / processor 440. The transmit processor 415 performs 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 signals for the first, second, and fourth information blocks and the physical layer signals for the control channel candidate in this application 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 RF signals. At the receiving end, each receiver 456 receives the RF signal via 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 performs various signal reception processing functions for the L1 layer. The signal reception and processing function includes receiving the physical layer signals of the first information block, the second information block, and the fourth information block in this application and the physical layer signals of the control channel alternative, 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 high-level information included in the first information block, the second information block, and the fourth information block in this application. The controller / processor may be associated with a memory 480 that stores program code and data. The memory 480 may be referred to as a computer-readable medium.

[0319] In uplink (UL) transmission, similar to downlink transmission, high-layer information, including the high-layer information included in the third information block in this application, is generated by the controller / processor 490 and then passed through the transmit processor 455 to perform various signal transmission processing functions for the L1 layer (i.e., physical layer). This includes generating a physical layer signal carrying the third information block in this application. The transmit processor 455 then maps the signal to the antenna 460 via the transmitter 456 and transmits it in the form of a radio frequency signal. Receivers 416 receive the radio frequency signal via their corresponding antennas 420. Each receiver 416 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receive processor 412. The receive processor 412 performs various signal reception processing functions for the L1 layer (i.e., physical layer), including receiving and processing the physical layer signal carrying the third information block in this application, and then provides data and / or control signals to the controller / processor 440. The L2 layer functions implemented by the controller / processor 440 include interpreting high-layer information, including interpreting the high-layer information carried in the third information block in this application. The controller / processor may be associated with a cache 430 that stores program codes and data. The cache 430 may be a computer-readable medium.
