Description

BACKGROUND

Technical Field

The present application relates to transmission methods and devices in wireless communication systems, and in particular to a method for improving efficiency and reducing interruptions concerning multiple network communications in wireless communications.

Related Art

Application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance demands on systems. In order to meet different performance requirements of various application scenarios, the 3rd Generation Partner Project (3GPP) Radio Access Network (RAN) #72 plenary decided to conduct the study of New Radio (NR), or what is called fifth Generation (5G). The work Item (WI) of NR was approved at the 3GPP RAN #75 plenary to standardize the NR.

In communications, both Long Term Evolution (LTE) and 5G NR involves correct reception of reliable information, optimized energy efficiency ratio (EER), determination of information validity, flexible resource allocation, elastic system structure, effective information processing on non-access stratum (NAS), and lower traffic interruption and call drop rate, and support to lower power consumption, which play an important role in the normal communication between a base station and a User Equipment (UE), rational scheduling of resources, and also in the balance of system payload, thus laying a solid foundation for increasing throughput, meeting a variety of traffic needs in communications, enhancing the spectrum utilization and improving service quality. Therefore, LIE and 5G are indispensable no matter in enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communication (URLLC) or enhanced Machine Type Communication (eMTC). And a wide range of requests can be found in terms of Industrial Internet of Things (IIoT), Vehicular to X (V2X), Proximity Services (ProSe), and Device to Device (D2D), Unlicensed Spectrum communications, and monitoring on UE communication quality, network plan optimization, Non-Terrestrial Network (NTN) and Terrestrial Network (TN), Dual connectivity system, or a system using Sidelink, or combined, radio resource management and multi-antenna codebook selection, as well as signaling design, neighbor management, traffic management and beamforming. Information is generally transmitted by means of broadcast/multicast and unicast, and all these ways are beneficial to fulfilling the above requests and make up an integral part of the 5G system. To enlarge the coverage of the network and improve the system's reliability, information can also be forwarded via relaying. As the capability of a communication terminal gets stronger, the communication terminal can be equipped with one Subscriber Identity Module (SIM) card or multiple SIMs. When using multiple SIMs and connecting to multiple networks, how a transceiving module of the terminal coordinates between different networks becomes a key issue.

As the number and complexity of system scenarios increases, more and more requests have been made on reducing interruption rate and latency, strengthening reliability and system stability, increasing the traffic flexibility and power conservation, and in the meantime the compatibility between different versions of systems shall be taken into account for system designing.

SUMMARY

When a UE (i.e., user equipment, or terminal/cellphone) needs to be in communication with multiple networks, particularly when using multiple corresponding SIMs, there arises a problem of coordination among the networks. When the UE's own hardcore is not sufficient enough to support its communication with two networks simultaneously, independently, in parallel and free from any influence, if a certain degree of coordination can be provided based on the network assistance or initiated by the UE itself, mutual influence between two networks can be avoided. For instance, when the UE needs communications with another network but the current network also indicates its data transmission or reception, the two networks may be mutually influenced. Some UEs may be equipped with two receivers but with only one transmitter, which means that these UEs may be able to receive signals from two networks simultaneously but can only transmit to one network; there are of course some UEs that can only receive signals from one network at the same time; whatever the case may be, most of such UEs cannot transmit signals to two networks simultaneously. The two SIMs or multiple SIMs of the UE may be provided by different operators, which makes the coordination among the networks very limited, so it is hard to coordinate only depending on the networks, and even worse, for the sake of privacy, it is necessary to forbid the networks from conveying user information to one another. When a UE leaves a network temporarily for a short time for receiving or transmitting in another network, the impact on the current network is acceptable, for instance to update a serving cell in another network. The UE, which is still connected with the network from which it leaves, will not transmit and/or receive data temporarily, but will still be under the control and management of the network. The control and the management include many aspects, for instance the triggering of some events in some cases (e.g., the expiration of a timer), which probably need transmission of some data or reports. However, during its temporary absence from the current network the UE cannot transmit any data or report, and this will lead to some contradictions, which, if not handled properly, are prone to cause the UE's disconnection. By offering a new method of controlling behaviors of the UE during its leave, the present application solves the above problem.

To address the above problem, the present application provides a solution.

It should be noted that if no conflict is incurred, embodiments in any node in the present application and the characteristics of the embodiments are also applicable to any other node, and vice versa. What's more, the embodiments in the present application and the characteristics in the embodiments can be arbitrarily combined if there is no conflict. Besides, it should be noted that the present application is also applicable to for instance communications of UAV (Unmanned Aerial Vehicle, IoT or IIoT, or scenarios with vehicle-mounted networks, NTN or TN, or UE with Reduced Capability (RedCap UE), or communication scenarios with wearables, where similar technical effects can be achieved. Additionally, the adoption of a unified solution for various scenarios contributes to the reduction of hardcore complexity and costs.

Besides, the method proposed by the present application can select according to various network configurations or events that shall be triggered, and adopt corresponding ways of handling; the handling includes controlling timers and controlling whether to execute events being triggered, as well as continuing executions after returning to the original network, where the controlling of timers is based on the fact that some events are triggered by the expiration of a timer, therefore controlling timers can be seen as an effective method.

Furthermore, the method provided in the present application can control the UE in leaving the current network as time permits, thus avoiding the uncertainty resulting from some behaviors or an absence during the procedures, as well as streamlining the design of protocols.

Furthermore, the method provided in the present application takes full account of the influence of the length of a timer on the handling of events; a certain timer will expire shortly after returning to the original network, which may still lead to that the UE can hardly process relevant events in a timely manner, so that consideration is paid only to the case of expecting events that can be triggered by an expired timer after having returned to the original network for a period of time, where the original network refers to the network that configures the certain timer mentioned above.

Embodiment 4

Embodiment 4 illustrates 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 in communication with each other in an access network.

The first communication device 450 comprises a controller/processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter/receiver 454 and an antenna 452.

The second communication device 410 comprises a controller/processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter/receiver 418 and an antenna 420.

In a transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, a higher layer packet from a core network is provided to the controller/processor 475. The controller/processor 475 provides functions of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resource allocation of the first communication device 450 based on various priorities. The controller/processor 475 is also in charge of HARQ operation, a retransmission of a lost packet and a signaling to the first communication device 450. The transmitting processor 416 and the multi-antenna transmitting processor 471 perform various signal processing functions used for the L1 layer (i.e., PHY). The transmitting processor 416 performs coding and interleaving so as to ensure a Forward Error Correction (FEC) at the second communication device 410 side and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, and M-QAM, etc.). The multi-antenna transmitting processor 471 performs digital spatial precoding, which includes precoding based on codebook and precoding based on non-codebook, and beamforming processing on encoded and modulated signals to generate one or more spatial streams. The transmitting processor 416 then maps each spatial stream into a subcarrier. The mapped symbols are multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multicarrier symbol streams. After that the multi-antenna transmitting processor 471 performs transmission analog precoding/beamforming on the time-domain multicarrier symbol streams. Each transmitter 418 converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency (RF) stream, which is later provided to different antennas 420.

In a transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal via a corresponding antenna 452. Each receiver 454 recovers information modulated to the RF carrier, and converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 perform signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs reception analog precoding/beamforming on a baseband multicarrier symbol stream provided by the receiver 454. The receiving processor 456 converts baseband multicarrier symbol streams which have gone through reception analog precoding/beamforming operations from time domain to frequency domain using FFT. In frequency domain, physical layer data signals and reference signals are de-multiplexed by the receiving processor 456, where the reference signals are used for channel estimation while data signals are processed in the multi-antenna receiving processor 458 by multi-antenna detection to recover any spatial stream targeting the first communication device 450. Symbols on each spatial stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. Then the receiving processor 456 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted by the second communication device 410 on the physical channel. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 provides functions of the L2 layer. The controller/processor 459 can be associated with a memory 460 that stores program code and data. The memory 460 can be called 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 a transport channel and a logical channel, packet reassembling, decrypting, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer. Or various control signals can be provided to the L3 for processing.

In a transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, the data source 467 is configured to provide a higher-layer packet to the controller/processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to a transmitting function of the second communication device 410 described in the transmission from the second communication node 410 to the first communication node 450, the controller/processor 459 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor 459 is also responsible for a retransmission of a lost packet, and a signaling to the second communication device 410. The transmitting processor 468 performs modulation and mapping, as well as channel coding, and the multi-antenna transmitting processor 457 performs digital multi-antenna spatial precoding, including precoding based on codebook and precoding based on non-codebook, and beamforming. The transmitting processor 468 then modulates generated spatial streams into multicarrier/single-carrier symbol streams. The modulated symbol streams, after being subjected to analog precoding/beamforming in the multi-antenna transmitting processor 457, are provided from the transmitter 454 to each antenna 452. Each transmitter 454 first converts a baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, and then 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 function of the second communication device 410 is similar to the receiving function of 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 a radio frequency signal via a corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly provide functions of the L1 layer. The controller/processor 475 provides functions of the L2 layer. The controller/processor 475 can be associated with the memory 476 that stores program code and data. The memory 476 can be called a computer readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller/processor 475 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decrypting, header decompression, control signal processing so as to recover a higher-layer packet from the first communication device (UE) 450. The higher-layer packet coming from the controller/processor 475 may be provided to the core network.
