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 Radio interface (NR) technology (or fine Generation, 5G) is decided over 72 sessions of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network), and standardization Work on NR is started over WI (Work Item) where NR passes through 75 sessions of 3GPP RAN.

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, the scalable system structure, high-efficiency non-access stratum information processing, low service interruption and disconnection rate, for low power consumption support, which is for normal communication of base stations and user equipments, for reasonable scheduling of resources, the method has important significance for balancing system load, can be said to be high throughput rate, meets Communication requirements of various services, improves spectrum utilization rate, and improves the quality of service, and is essential for eMBBs (enhanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communication) or eMTCs (enhanced Machine Type Communication). Meanwhile, in the Internet of Things in the field of the IIoT (Industrial Internet of Things), in V2X (Vehicular to X), in communication between devices (Device to Device), in communication of unlicensed spectrum, in user communication quality monitoring, in Network planning optimization, in NTN (Non terrestrial Network communication), in TN (terrestrial Network communication), in a Dual connectivity (Dual connectivity) system, in a mixture of the above various communication modes, in radio resource management and codebook selection of multiple antennas, in signaling design, neighborhood management, traffic management, and in beamforming, there is a wide demand for transmission of information, which is divided into broadcast and unicast, and both transmission modes are indispensable for a 5G system, because they help to meet the above demand.

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 a plurality of communication scenarios, especially in a wireless network supporting a new generation of broadcast multicast, a radio bearer is configured for a user for a specific service, the configured radio bearer may be a unicast bearer or a non-unicast bearer, and may be a non-unicast bearer in a cell, or a unicast bearer in a cell, and may be configured as a unicast bearer at a certain time or a non-unicast bearer at another time, so that the flexibility of the network and the flexibility of resource allocation can be greatly increased, and simultaneously, system resources can be saved, which is an important technical content of 5G broadcast multicast. However, such a configuration may encounter a series of problems, namely, when to configure what radio bearer, how to configure, how to perform handover if the type of radio bearer is different and how to perform handover when a user moves between different cells, what auxiliary methods are needed to perform appropriate handover and selection to reduce data interruption; similar problems exist when the type of radio bearer changes within a cell. Non-unicast bearers, including broadcast or multicast bearers, which may be for a cell, a small area, or for a large area with many users in the area, are very different from unicast bearers, and thus such bearers have difficulty in considering each user, the serving cell does not even know which users are receiving or interested in receiving, because there is no exact context information about receiving such services for these users, and thus it is difficult to perform optimization and involvement for each specific user like unicast bearers, and mishandling may cause a loss of interruption of data reception. It is therefore important to let the serving cell have enough information to make a correct decision, which may include the user's condition, the user's reception condition, the user's interest condition, the user's resource usage condition, the service requirements and service transmission conditions for different services, different bearers, etc.

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

The application discloses a first node to be used for wireless communication, comprising:

the first receiver is used for determining a first service set, wherein the services included in the first service set are non-unicast services;

a first transmitter to transmit second signaling indicating an interest in a first subset of traffic and a second subset of traffic; the first subset of traffic and the second subset of traffic both belong to the first set of traffic;

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

when a user just enters a new cell, or a cell transmitting broadcast multicast service through a non-unicast bearer is switched to a cell transmitting broadcast multicast service through a unicast bearer, or a cell transmitting broadcast multicast service through a non-unicast bearer is switched to a unicast bearer to transmit the same service, a key problem is encountered, namely how to assist a serving cell to carry out proper configuration, and the problem of data loss or even interruption in the process of bearer selection or switching is encountered when the processing is not proper. Since the network may not maintain the user context in a cell using non-unicast bearer, and the non-unicast bearer does not support the feedback of the ue, it is difficult for the serving cell to know the user reception. When the bearer types of the serving cell are switched, especially when the broadcast multicast service is transmitted in a unicast manner, if a new independent bearer is directly established between the user and the server according to the conventional method, a long-time service interruption is caused, so that it is difficult to avoid data loss. There is therefore a need for a serving cell to perform bearer selection or handover at the access plane, with the user providing appropriate meaningful assistance information. According to the method and the device, the unicast bearer can be helped to be quickly established by the service cell through the indication of the second signaling, particularly through the unicast bearer and the service set generated by associating the unicast bearer with the service interested by the user, so that a long message flow is avoided, and the method and the device are simpler, more convenient and quicker than the traditional method.

the traditional unicast service cannot directly establish radio bearer through the request of the access layer of the user; a user needs to establish a connection with a core network through signaling of a non-access stratum, for example, through a PDU session, a request is made to a functional entity of the core network, for example, an AMF, when the core network is established, if some verification work needs to be performed, the core network establishes an interface to an access network, and the access network can establish a radio bearer for the user, and then can transmit a service. For broadcast multicast services, although broadcast or multicast in nature, unicast radio bearers may be used when transmitted at the bottom layer, e.g. the access stratum, e.g. when the number of users in a service area is not very large, the base station may choose to use unicast radio bearers more efficiently. The traditional flow for establishing unicast bearer is very long for 5G broadcast multicast, and for a broadcast multicast area, a user only needs to request a network once through a non-access layer, and does not need to request a core network again when the bearer changes or is switched over, so that the functional division between the core network and the access network becomes very clear, and the core network is facilitated to transmit by using a uniform data transmission mode. Meanwhile, the access network directly controls the type of the wireless bearer, which is beneficial to reducing time delay and reducing data loss. This is just an advantage of the method proposed in the present application.

the method provided by the application can help the serving cell to directly initiate a radio bearer establishment process by providing the serving cell with a service set related to unicast bearer and a service set related to non-unicast bearer, so that the existing protocol architecture is compatible to the maximum extent, namely, the establishment and release of the radio bearer are controlled by the base station, a user generally does not need to directly request or explicitly request, but the base station is assisted to configure in an implicit mode, so that the method is very concise and low in complexity, different bearer services are reported together and the complexity is the lowest, the signaling overhead is reduced, so that the method provided by the application can take multiple functions into account, and the complexity is very low.

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 PHY 301.

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 layer L2. 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 functionality 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. 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. 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.
