application date of the original application: 12 and 15 months in 2017

- -application number of the original application: 201780094859.5

The invention of the original application is named: method and device in communication node for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus in non-terrestrial wireless communication.

Background

Application scenes of a future wireless communication system are more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of multiple application scenarios, a New air interface technology (NR, New Radio) (or 5G) is determined to be studied in 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 guilds, and standardization Work on NR starts after passing through WI (Work Item) of the New air interface technology (NR, New Radio) in 3GPP RAN #75 guilds.

In order to be able to adapt to various application scenarios and meet different requirements, a research project of Non-Terrestrial Networks (NTN) under NR was also passed on 3GPP RAN #75 full meeting, the research project was started in version R15, and then WI was started in version R16 to standardize the related technologies.

Disclosure of Invention

In the NTN network, User Equipment (UE) and a satellite or an aircraft communicate via a 5G network, the coverage area of the satellite or the aircraft on the ground is much larger than that of a conventional base station, and the difference between the delays of different UEs reaching a service satellite or an aircraft under the same satellite or aircraft coverage is large due to the angle and the altitude. This delay difference can be up to more than a dozen milliseconds (e.g., the maximum delay difference for a geostationary satellite is around 16 milliseconds) as calculated in 3GPP TR 38.811. On the other hand, many satellites or aircraft may be equipped with a large number of antennas to support spatially multiplexed transmissions to different geographical areas of the ground. In the existing NR system, the design of a synchronization broadcast Channel (i.e., SS/PBCH Block) can support 64 analog beams at most, and a synchronization transmission with a delay difference of less than 5 milliseconds can be distinguished by an indication of an uplink Random Access Channel (PRACH), thereby ensuring the accuracy of uplink transmission Timing (generally TA, Timing Advance). As can be seen from the above comparison, the existing synchronous broadcast design in NR cannot meet the requirements of large delay difference and more antenna deployment in NTN network.

The application provides a solution to the problem that the synchronous broadcast in the NR NTN communication supports large delay variation and more antenna deployment. It should be noted that, without conflict, the embodiments and features in the embodiments in the base station apparatus of the present application may be applied to the user equipment, and vice versa.

Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for the user plane and the control plane according to the present application, as shown in fig. 3. Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for a first type of communication node device (UE) and a second type of communication node device (gNB, eNB or satellite in NTN) in 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 the PHY301, and is responsible for a link between the first type of communication node device and the second type of communication node device through the PHY 301. In the user plane, the L2 layer 305 includes a MAC (media 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 type of communication node device on the network side. Although not shown, the first type of communication node device may have several upper layers above the L2 layer 305, 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., far end UE, server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, security by ciphering the data packets, and handoff support between communication node devices of the second type to communication node devices of the first type.

In the control plane, the radio protocol architecture for the first type of communication node device and the second type of communication node device is substantially the same for the physical layer 301 and the L2 layer 305, but without header compression functionality for the control plane. The Control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3 (layer L3).

Receive processor 452 performs various signal receive processing functions for the L1 layer (i.e., the physical layer) including decoding, deinterleaving, descrambling, demodulation, depredialing, and physical layer control signaling extraction, among others. The transmitter 456 is configured to convert baseband signals provided from the transmit processor 455 into radio frequency signals and transmit the radio frequency signals via the antenna 460, and the receiver 456 is configured to convert radio frequency signals received via the antenna 460 into baseband signals and provide the baseband signals to the receive processor 452.

The controller/processor 440 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the UE450, such as the first information, second information, third information, and fourth information in this application, 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 decoding and interleaving to facilitate Forward Error Correction (FEC) at the UE450 and modulation of the baseband signal based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)), splitting the modulation symbols into parallel streams and mapping each stream to a respective multi-carrier subcarrier and/or multi-carrier symbol, which are then mapped to the antenna 420 by the transmit processor 415 via the transmitter 416 for transmission as a radio frequency signal. In the present application, the first wireless signal and the first information, the second information, the third information, and the fourth information are mapped to a target air interface resource by the transmission processor 415 on a corresponding channel of a physical layer, and are mapped to the antenna 420 via the transmitter 416 to be transmitted in the form of a radio frequency signal.
