Description

Method and equipment used 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 method and apparatus for reducing service interruption, improving service continuity, enhancing reliability, and improving security in 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 various application scenarios, research on New air interface technology (NR, new Radio) (or Fifth Generation, 5G) is decided over #72 sessions of 3GPP (3 rd Generation Partner Project) RAN (Radio Access Network), and standardization Work on NR begins over 3GPP RAN #75 sessions over WI (Work Item ) of NR.

In Communication, both LTE (Long Term Evolution) and 5G NR relate to Reliable accurate reception of information, optimized energy efficiency ratio, determination of information validity, flexible resource allocation, scalable system structure, efficient non-access stratum information processing, lower service interruption and dropped rate, support for Low power consumption, which is important for normal Communication between a base station and user equipment, reasonable scheduling of resources, and balance of system load, so to speak, high throughput rate, meet Communication requirements of various services, improve spectrum utilization rate, and improve foundation of service quality, and are indispensable for enhanced Mobile BroadBand (eMBB) Communication, ultra Mobile Low Latency (ullc) or enhanced Machine Type Communication (eMTC). Meanwhile, in the Internet of Things in the Industrial field, in V2X (Vehicular to X), communication between devices (Device to Device) is performed, in communication of unlicensed spectrum, in user communication quality monitoring, network planning optimization, in NTN (Non-terrestrial Network communication), in TN (terrestrial Network communication), in Dual connectivity (Dual connectivity) system, in wireless resource management and codebook selection of multiple antennas, there are wide requirements in signaling design, neighborhood management, service management, and beamforming, and the transmission mode of information is divided into broadcast and unicast, and both transmission modes are indispensable to the 5G system because they help the UE to connect to the Network, and may be connected directly or through relay.

With the continuous increase of the scenes and the complexity of the system, higher requirements are put forward on the reduction of the interruption rate, the reduction of the time delay, the enhancement of the reliability, the enhancement of the stability of the system, the flexibility of the service and the saving of the power, and meanwhile, the compatibility among different versions of different systems needs to be considered when the system is designed.

Disclosure of Invention

In various communication scenarios, the use of multiple antennas may be involved, for example, to transmit information to a user via multiple transmission points (multi-TRP, mTRP, multiple transmission points, or multiple transmission and reception points). Using mTRP may be helpful in improving throughput and increasing coverage in different situations. To further improve performance, the mTRP may include multiple TRPs from the same physical cell or from different physical cells. A serving cell in a 5G NR generally has a certain relationship with a physical cell, and it is generally considered that a serving cell only includes a physical cell and a physical cell only belongs to a serving cell. Therefore, problems arise when TRPs from different physical cells are provided to users through one cell, a feature that is not supported by many aspects of current 5G systems. On the other hand, in the current communication system, if the user detects the radio link failure, the radio link failure information is stored, for example, the radio link failure information is stored by its own state variable, and the stored radio link failure information is reported to the network when the network is accessed next time or when some is appropriate, which is very helpful for network optimization. The radio link failure information may preferably include measurements of reference signals before failure, by which the network can assess the coverage situation. The network will not typically configure all reference signals as reference signals for monitoring for radio link failure. The detection of radio link failure is closely related to the configured reference signal resource for detecting/monitoring radio link failure, so that it is better to report which reference signals are used for radio link monitoring at the time of reporting. For mTRP, a new radio link monitoring configuration method may be adopted, that is, reference signals belonging to different physical cells or reference signals of TRP are configured together as reference signals for radio link monitoring, which is beneficial to obtain a more real and accurate result, so when a radio link fails, the radio link failure information needs to determine which reference signals of different physical cells or reference signals of TRP are used for radio link monitoring, which is beneficial to further optimization of the base station on the network. The current 5G system cannot support the above requirements.

In view of the above, the present application provides a solution.

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 and second nodes and the two UEs through PHY301.

Example 4

Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present 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 communications 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 multiple antenna receive processor 472, a multiple 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, at the second communication device 410, upper layer data packets from the core network are provided to the controller/processor 475. The controller/processor 475 implements the functionality of the L2 layer. In transmissions from the second communications device 410 to the first communications device 450, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communications 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., the physical layer). The transmit processor 416 implements coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 410, as well as mapping of signal constellation 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 performs digital spatial precoding, including codebook-based precoding and non-codebook based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, 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 the physical channels carrying the time-domain multicarrier symbol streams. 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 multi-antenna transmit processor 471 into a radio frequency stream that is then provided to a different antenna 420.

In a transmission from the second communications apparatus 410 to the first communications apparatus 450, each receiver 454 receives a signal through its respective antenna 452 at the first communications apparatus 450. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream that is provided to a receive processor 456. Receive processor 456 and multi-antenna receive processor 458 implement the various signal processing functions of 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. Receive processor 456 converts the baseband multicarrier symbol stream after the receive 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 signals and the reference signals to be used for channel estimation are demultiplexed by the receive processor 456, and the data signals are subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered at 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 transmitted by the second communications device 410 on the physical channel. The upper layer data and control signals are then provided to a 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 transmissions from the second communications device 410 to the second communications device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from the core network. The upper layer packet is then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

In a transmission from the first communications device 450 to the second communications device 410, a data source 467 is used at the first communications 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 send function at the second communications apparatus 410 described in the transmission from the second communications apparatus 410 to the first communications apparatus 450, the controller/processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to said second communications 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, by the multi-antenna transmit processor 457, and then the transmit processor 468 modulates the resulting spatial streams into multi-carrier/single-carrier symbol streams, which are provided to the different antennas 452 via the transmitter 454 after analog precoding/beamforming in the multi-antenna transmit processor 457. 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 the radio frequency symbol stream to the antenna 452.

In a transmission from the first communication device 450 to the second communication device 410, the functionality at the second communication device 410 is similar to the receiving functionality 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 an rf signal through its respective antenna 420, converts the received rf signal to a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multiple antenna receive processor 472 collectively implement the functions of the L1 layer. The controller/processor 475 implements the L2 layer functions. The controller/processor 475 can be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In transmission from the first communications device 450 to the second communications device 410, the controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from the UE 450. Upper layer data packets from the controller/processor 475 may be provided to a core network.
