Description
The application is a divisional application of the following original application:
Filing date of the original application: 2021, 03, 24
Number of the original application: 202110313749.1
-the name of the application of the original application: method and apparatus in a 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 method and apparatus with a large delay.
Background
When the Counter (Counter) N310 reaches a maximum value, indicating that a physical layer problem occurs, and starting a (Start) timer T310; when the timer T310 expires (Expire), it is determined that a radio link failure has occurred. During the operation of timer T310, when the UE satisfies the measurement configuration and transmits a measurement report, timer T312 is started; stopping the timer T312 when an RRC connection reconfiguration message carrying synchronization information is received; when the timer T312 expires, an RRC connection re-establishment procedure is performed or an rrc_idle state is entered. When the MCG (Master Cell Group ) fails in radio link, if the condition of MCG link fast recovery (Fast MCG Link Recovery) is satisfied, the UE transmits an MCG failure information message and starts a timer T316; stopping the timer T316 when the UE receives the RRC connection release message or the RRC connection reconfiguration message and completes RRC connection reconfiguration; when the timer T316 expires, the UE performs an RRC connection re-establishment procedure. The current radio link failure (Radio Link Failure, RLF) related timers (Timer) are only for the terrestrial network (Terrestrial Network ). In face of the increasing communication demands, 3GPP (3 rd Generation Partner Project, third generation partnership project) starts to study Non-terrestrial network communication (Non-Terrestrial Network, NTN), and 3GPP ran#80 conferences decide to develop a "NR (New Radio, new air interface) supporting solution for Non-terrestrial network" study project.
Disclosure of Invention
The transmission delay of the NTN network is much longer than that of the TN network. Some timers have little relation with transmission delay, such as timer T310; however, some timers require signaling interaction between the UE and the base station during operation, and are inevitably subject to large delays, such as timer T312. When the UE starts T312, it needs to wait to receive the RRC connection reconfiguration message during the operation of timer T312, and the delay time for GEO (Geostationary satellite, geosynchronous satellite) may reach 500ms, during which expiration of timer T310 easily occurs, resulting in the timer T312 to stop. Similar problems occur for timers T310 and T316. Thus, in NTN, joint design for delay sensitive timers and delay insensitive timers is required.
The present application provides a solution to the above problems. In the description for the above problems, NTN scenes are taken as an example; the application is also applicable to scenes such as TN, and achieves technical effects similar to those in NTN scenes. Furthermore, the adoption of a unified solution for different scenarios also helps to reduce hardware complexity and cost.

Example 3
Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture of a user plane and a control plane according to the application, as shown in fig. 3. Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, fig. 3 shows the radio protocol architecture for the control plane 300 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 herein as PHY301. Layer 2 (L2 layer) 305 is above PHY301 and includes a MAC (Medium Access Control ) sublayer 302, an RLC (Radio Link Control, radio link layer control protocol) sublayer 303, and a PDCP (Packet Data Convergence Protocol ) sublayer 304.

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.

Example 4
Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the application, as shown in fig. 4. Fig. 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.
The first communication device 450 includes a controller/processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter/receiver 454, and an antenna 452.
The second communication device 410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter/receiver 418, and an antenna 420.
In the transmission from the second communication device 410 to the first communication device 450, upper layer data packets from the core network are provided to a controller/processor 475 at the second communication device 410. The controller/processor 475 implements the functionality of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, a controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller/processor 475 is also responsible for retransmission of lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., physical layer). Transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 410, as well as mapping of signal clusters based on various modulation schemes, e.g., binary Phase Shift Keying (BPSK), quadrature Phase Shift Keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM). The multi-antenna transmit processor 471 digitally space-precodes the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. A transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes with reference signals (e.g., pilots) in the time and/or frequency domain, and then uses an Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying the time domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 to a radio frequency stream and then provides it to a different antenna 420.
In a transmission from the second communication device 410 to the first communication device 450, each receiver 454 receives a signal at the first communication device 450 through its respective antenna 452. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream that is provided to a receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions for the L1 layer. A multi-antenna receive processor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming operation from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, wherein the reference signal is to be used for channel estimation, and the data signal is subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in a receive processor 456 and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals that were transmitted by the second communication device 410 on the physical channel.
