Description

Method and equipment used for wireless communication

Technical Field

The present invention relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus for reducing power consumption efficiency, improving system reliability, and reducing communication interruption in wireless communication.

Background

In the future, the application scenes of the wireless communication system are more and 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 accurate reception of Reliable information, optimized energy efficiency ratio, determination of information validity, flexible resource allocation, a scalable system structure, efficient non-access stratum information processing, and reduction of service interruption and dropped, which are 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, meeting Communication requirements of various services, improving spectrum utilization, and improving service quality, and are essential for eMBB (enhanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communication) and eMTC (enhanced Machine Type Communication). Meanwhile, in IIoT (Industrial Internet of Things, in V2X (Vehicular to X), communication between devices (Device to Device) in V2X (vehicle to X), communication in unlicensed spectrum, user communication quality monitoring, network planning optimization, in NTN (Non terrestrial Network communication), in TN (terrestrial Network communication), in a mixture of the above various communication modes, in wireless resource management and codebook selection of multiple antennas, there are wide demands in signaling design, neighbor management, registration request management, tracking area update, in beamforming, and the information transmission mode is divided into broadcast and unicast, and both transmission modes are indispensable for a 5G system.

With the continuous increase of the scenes and the complexity of the system, higher requirements are provided for reducing interruption and time delay, enhancing reliability, enhancing the stability of the system, providing flexibility for services and saving power, and meanwhile, the compatibility among different versions of different systems needs to be considered during the design of the system.

Disclosure of Invention

In various communication scenarios, when a user moves or is required, a message needs to be updated, which may be periodic or aperiodic, and the message can be updated to a base station or a higher-layer network. For example, the system needs to communicate with the user, or the user needs to communicate with another user through the system, and the user needs to be determined to be reachable with the system. For example, in a 5G network, a system locates a user by paging, the user first initiates access, then establishes a wireless network link, and determines a security policy according to whether security is already activated, a service request may be sent to the network if it needs to be initiated, and a corresponding signaling procedure is needed if data needs to be updated. In the existing system, the accessibility of the user depends more on whether the user can update the information of the user in real time, which is necessary for the user in an idle state, but if the user cannot update in real time, the service quality may be caused to be in a problem. When the user finds a problem and updates the data, the loss which cannot be compensated is probably caused. There is a need for a way to help the user determine when to perform an update of a message, since too frequent updates may cause the system to be overloaded, resulting in a power drain on the user terminal. The coverage area of a cell is large, for example, an NTN cell is particularly prominent, so that the transmission delay of a user is large, and if the updating is not timely, more accumulated delay is caused, and therefore, a method is urgently needed to help the user to quickly and accurately update a message at a proper time and keep synchronization with a network.

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

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments in any node of the present application may be applied to any other node. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict. Furthermore, it should be noted that, in the above problem description, the IoT scenario is only an example of one application scenario of the solution provided in the present application; the application is also equally applicable to scenarios such as non-terrestrial networks, achieving technical effects similar to those in IoT scenarios. Similarly, the present application is also applicable to scenarios such as the presence of an UAV (Unmanned Aerial Vehicle), or an onboard network, to achieve technical effects in IoT-like scenarios. Furthermore, employing a unified solution for different scenarios (including but not limited to NTN and TN network scenarios) also helps to reduce hardware complexity and cost.

The application discloses a method in a first node used for wireless communication, comprising:

receiving a first signaling;

receiving a target signal in a first state;

wherein the target signal is used to determine a target identity, the target identity being related to a cell identity; the first signaling and the target identity are used to determine a first set of identities, the first set of identities relating to a registration request; a sender of the target signal is a cell other than a cell in which the first node resides; the first set of identities is used to trigger sending a first signal; the first signal carrying at least one identity of the first set of identities, the first signal being used for the registration request; a receiver of the first signal is different from a sender of the target signal; the first state is a radio resource control state other than a radio resource control connected state.

As an embodiment, the problem to be solved by the present application includes: when an area, e.g. a cell, comprises a plurality of identities, the network needs to determine the identities associated with a user terminal, since these identities are associated with the user's location or with specific resources. Especially when paging of these users is required, the basic situation of the users needs to be determined. The user needs some time in the process of updating the information, and in the time, the connection communication and the paging of the user can be affected, even interrupted or similar to the situation of being out of the service area. In a larger cell, especially in NTN networks, the delay is relatively long and the time affected is significant. The conventional method is to report the information actively when the user finds that the information needs to be updated and a new identifier needs to be associated, because the network may not be able to master the user's information when the user is in an idle state, and only the user can report the information. The aforementioned interruption is necessarily caused by the fact that the user updates when they find that an update is needed. Therefore, the method and the device can initiate the updating when the updating is about to be needed but not necessarily updated by obtaining the relevant identifications in advance and determining the set of identifications needing updating through the measurement of the user, thereby avoiding possible communication interruption.

As an example, compared with the conventional scheme, the method has the following advantages:

when the cell is large, especially an NTN cell, one cell may cover multiple TAs, and thus multiple TAs are indicated, and one UE, for example, an idle UE, cannot know exactly which TA it is in; the other party; in order to prevent the UE from frequently updating the TAs, the core network configures a plurality of TAs to the UE through the TAI list, and the TA does not need to be updated as long as the current TA is in the TA list; certainly, the TA list cannot be too large, too large area affected by the paging message is too large, and the paging load is too large. The general strategy is to configure into TAI list, not very large nor very small, according to the route of the UE or a circle around the current TA; however, since the UE cannot know its TA, it can only know that the UE is located in one cell, for example, an NTN cell, and one of the indicated TAs cannot determine whether the configured TAI list boundary is reached. The TA update can only initiate a TAU when the UE enters a new cell and finds that its TA is not in the new cell, but this may result in that a paging cannot be received within a period of time, especially for a communication system such as NTN with a large propagation delay. The TA update requires a procedure, and the registration request message can be sent after the fifth message after accessing the system, so that the UE may not receive the paging in several seconds in this period. According to the method and the device, the TA information of the surrounding cells is configured by the base station through the detection of the user and the first signaling, so that the user initiates a registration request to the core network when finding that the handover area is not yet available, the core network, such as an AMF (advanced radio frame) can be assisted to update the TAI list of the UE in real time, and the interruption of communication is avoided.

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 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 streams from 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 performs header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, performing 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. A transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding by a multi-antenna transmit processor 457 including codebook-based precoding and non-codebook based precoding, and beamforming, and the transmit processor 468 then modulates the resulting spatial streams into multi-carrier/single-carrier symbol streams, which are provided to different antennas 452 via a 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 functionality of the L1 layer. The controller/processor 475 implements 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 communication device 450 to the second communication 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.
