-the name of the invention of the original application: method and apparatus in a communication node for wireless communication

Technical Field

The present application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus in non-terrestrial wireless communications.

Background

Future wireless communication systems have more and more diversified application scenes, and different application scenes have different performance requirements on the system. To meet different performance requirements of various application scenarios, research on a New air interface technology (NR, new Radio) (or 5G) is decided on the 3GPP (3 rd Generation Partner Project, third generation partnership project) RAN (Radio Access Network ) #72 full-time, and standardization Work on NR is started on the 3GPP RAN #75 full-time WI (Work Item) that passes the New air interface technology (NR, new Radio).

In order to be able to adapt to various application scenarios and meet different requirements, a research project of Non-terrestrial networks (NTN, non-Terrestrial Networks) under NR is also passed on the 3gpp ran #75 meeting, which starts in R15 version and then starts WI in R16 version to standardize the related art.

Disclosure of Invention

In NTN networks, user Equipment (UE) and satellites or aircrafts communicate via a 5G network, where the coverage of the satellites or aircrafts on the ground is much larger than that of a conventional base station, while the time delay for different User Equipment under the coverage of the same satellite or aircrafts to reach a service satellite or aircraft varies greatly due to angle and altitude. According to the calculation in 3gpp tr38.811, this delay difference may reach more than ten milliseconds (e.g. the maximum delay difference under a geostationary satellite is around 16 milliseconds). 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 the synchronous broadcast channel (i.e. SS/PBCH Block) can support at most 64 analog beams, and meanwhile, the synchronous transmission with a delay difference of less than 5 ms can be distinguished by the indication of the uplink random access channel (PRACH, physical Random Access Channel), so as to ensure the accuracy of the 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 differences and more antenna deployment in NTN networks.

The present application provides a solution to the problem of supporting large delay differences and more antenna deployments for synchronized broadcast in NR NTN communications.

Example 3

Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture according to one user plane and control plane of the present application, as shown in fig. 3. Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane and a control plane, fig. 3 shows the radio protocol architecture for a first type of communication node device (UE) and a second type of communication node device (gNB, satellite in eNB or 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 PHY301. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first type of communication node device and the second type of communication node device through PHY301. In the user plane, the L2 layer 305 includes a MAC (MediumAccess Control ) sublayer 302, an RLC (Radio Link Control, radio link layer control protocol) sublayer 303 and a PDCP (Packet Data Convergence Protocol ) sublayer 304, which are terminated at the second type of communication node device on the network side. Although not shown, the first type of communication node apparatus may have several upper layers above the L2 layer 305, including a network layer (e.g., 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., remote 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 handover support for first type communication node devices between second type communication 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 the various radio resources (e.g., resource blocks) in one cell among the first class of communication node devices. The MAC sublayer 302 is also responsible for HARQ operations. 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 there is no header compression function for the control plane. The control plane also includes an RRC (Radio Resource Control ) sublayer 306 in layer 3 (L3 layer). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second type of communication node device and the first type of communication node device.
