Description
The application is a divisional application of the following original application:
Filing date of the original application: 2020, 05 and 09 days
Number of the original application: 202010384934.5
-the name of the application of the original application: method and apparatus in a 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 method and apparatus for radio link failure and recovery.
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), a radio link failure is determined to occur (Radio Link Failure, RLF). Release 16 studied MCG (Master Cell Group, main cell group) Link fast recovery (Fast MCG Link Recovery) in the "Dual connectivity and Carrier aggregation enhancement (ehanced Dual Connectivity and Carrier Aggregation, eDCCA)" Work Item (Work Item, WI), and recovered the MCG link through the SCG (Secondary Cell Group ) after supporting MCG RLF, when MCG Link fast recovery was performed, a timer T316 was started and an MCGFailureinformation Message (Message) was sent.
Disclosure of Invention
The existing 3GPP (3 rd GenerationPartner Project, third generation partnership project) protocol is not co-designed for timer T310 and timer T316, and when a User Equipment (UE) fails an MCG radio link during the operation of timer T310, such as a random access problem (random access protocol) or a maximum number of retransmissions (RLC-MaxNumRetx) is reached by the RLC layer, according to the prior art, if a condition for fast recovery of the MCG link is met, the UE does not trigger a radio resource control (Radio Resource Control, RRC) connection re-establishment (retransmission) procedure, but performs an MCG failure information (MCG Failure Information) procedure, and starts timer T316, and during the operation of timer T316, timer T310 continues to operate until a stop or an expiration. During the operation of the timer T316, if the expiration of the timer T310 occurs, the UE performs an MCG link fast recovery procedure or an RRC reestablishment procedure or enters an RRC IDLE state (rrc_idle) according to the expiration behavior of the timer T310, resulting in the timer T316 to stop and terminate the current MCG link fast recovery procedure. In one aspect, expiration of timer T310 during operation of timer T316 may result in a rapid recovery failure of the MCG link; on the other hand, when RLF occurs, the UE enters the MCG link fast recovery procedure first, and since the timer T310 expires and then jumps out of the MCG link fast recovery procedure and then performs RRC reestablishment, the delay of UE link recovery is increased, and unnecessary signaling overhead is caused. Similarly, similar problems occur with timers of RLF, such as timer T312.
The present application provides a solution to the above problems. In the description for the above problems, a ground network communication (Terrestrial Network, TN) scenario is taken as an example; the application is also applicable to Non-terrestrial transmission scenes, for example, and achieves technical effects similar to those in Non-terrestrial network communication (Non-Terrestrial Network, NTN) scenes. Furthermore, the adoption of a unified solution for different scenarios also helps to reduce hardware complexity and cost.

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 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. The upper layer data and control signals are then provided to the controller/processor 459. The controller/processor 459 implements the functions of the L2 layer. The controller/processor 459 may be associated with a memory 460 that stores program codes and data. Memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the second communication device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. The upper layer packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.
In the transmission from the first communication device 450 to the second communication device 410, a data source 467 is used at the first communication device 450 to provide upper layer data packets to a controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit functions at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller/processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations, implementing L2 layer functions for the user and control planes. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming, with the multi-antenna transmit processor 457 performing digital multi-antenna spatial precoding, after which the transmit processor 468 modulates the resulting spatial stream into a multi-carrier/single-carrier symbol stream, which is analog precoded/beamformed in the multi-antenna transmit processor 457 before being provided to the different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and provides it to an antenna 452.
In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals to baseband signals, and provides the baseband signals to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement the functions of the L1 layer. The controller/processor 475 implements L2 layer functions. The controller/processor 475 may be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, a controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the UE 450. Upper layer packets from the controller/processor 475 may be provided to the core network.
