Technical Field

The present application relates to the field of communications technologies, and in particular, to a wireless communication method and apparatus, a terminal, and a network device.

Background

The third Generation Partnership project (3 rd Generation Partnership project,3 gpp) is directed to the formulation of communication protocol standards. Among them, the existing communication protocol standard has been described with respect to Multimedia Broadcast Multicast Service (MBMS) in the communication process.

However, for multicast and/or broadcast service (MBS) services, there are two main transmission modes of the air interface between the network device and the terminal: multicast/broadcast and unicast. Wherein, for unicast traffic, the transmission mode of the air interface between the network device and the terminal is a unicast mode. Since the terminal in the connected state can receive multicast/broadcast services from the network device, and can also receive unicast services from the network device at the same time in some specific scenarios, further research is needed for scenarios of receiving multiple types of services at the same time.

With reference to the above description, before describing the wireless communication method provided in the embodiments of the present application in detail, relevant contents related to the embodiments of the present application are described.

1. Core network

The core network in the embodiment of the application is composed of core network elements. The core network element may also be referred to as core network equipment, and is a network element deployed in a core network. Such as a core network control plane network element or a core network user plane network element. The core network in the embodiment of the present application may be an Evolved Packet Core (EPC), a 5G core network (5G core network), or may be a new core network in a future communication system. For example, the 5G core network is composed of a set of network elements, and implements Access and Mobility Management functions (AMF) for Mobility Management and other functions, user Plane Function (UPF) for providing packet routing and forwarding and QoS (Quality of Service) Management functions, session Management Function (SMF) for providing Session Management, IP address allocation and Management functions, and the like. The EPC may be composed of a Mobility Management Entity (MME) providing functions such as Mobility Management and Gateway selection, a Serving Gateway (S-GW) providing functions such as packet forwarding, and a PDN Gateway (P-GW) providing functions such as terminal address allocation and rate control. For Multicast Broadcast Service (MBS), the core network may include several new network elements to implement functions such as packet forwarding, MBS conference management, qoS management, and transmission mode switching (switching between unicast and Multicast/Broadcast transmission modes). Alternatively, the functions may be implemented by existing core network elements.

2. Uplink and downlink communications

In the embodiment of the present application, uplink communication may also be referred to as uplink transmission, which refers to unidirectional communication from a terminal to a network device. Wherein the communication link for uplink communication is an uplink. The data transmitted on the uplink is uplink data. The transmission direction of the uplink data is the uplink direction. Similarly, the downlink communication in the embodiment of the present application may also be referred to as downlink transmission, which refers to unidirectional communication from the network device to the terminal. Wherein, the communication link for the downlink communication is a downlink. The data transmitted on the downlink is downlink data. The transmission direction of the downlink data is the downlink direction.

3. Multimedia Broadcast Multicast Service (MBMS)

The MBMS service is a service introduced in 3GPP Release 6 (Release 6, R6). The MBMS service is a technology for transmitting data from one data source to a plurality of terminals by sharing network resources, and provides a multimedia service while effectively using the network resources to implement a broadcast multicast of the multimedia service at a higher rate (256 kbps).

Since the MBMS spectrum efficiency in the 3GPP R6 is low and is not sufficient to effectively carry the operation of the mobile phone or television type service, in the LTE communication system, the 3GPP explicitly proposes to enhance the support capability for the downlink high-speed multimedia broadcast multicast service, and determines the design requirements for the physical layer and the air interface.

Enhanced multimedia broadcast multicast service (E-MBMS) is introduced to LTE communication systems by 3gpp R9. E-MBMS proposes the concept of Single Frequency Network (SFN), i.e. a uniform frequency is used to transmit data in all cells simultaneously, but synchronization between cells is guaranteed. The method can greatly improve the distribution of the integral signal-to-noise ratio of the cell, correspondingly and greatly improve the spectrum efficiency, and realizes the broadcasting and multicasting of the service based on the IP multicasting protocol.

In LTE/LTE-a, MBMS has only a broadcast bearer mode, and no multicast bearer mode. Meanwhile, the reception of the MBMS service is applicable to terminals in an RRC CONNECTED state (RRC _ CONNECTED) or an RRC IDLE state (RRC _ IDLE).

To sum up, for multicast/broadcast service (MBS) service, there are two main transmission modes of the air interface between the network device and the terminal: multicast/broadcast and unicast. Since the terminal in the connected state can receive multicast/broadcast services from the network device, and can also receive unicast services from the network device at the same time in some specific scenarios, further research is needed for scenarios in which multiple types of services are received at the same time.

In conjunction with the above description, an embodiment of the present application provides a flow chart of a wireless communication method, please refer to fig. 2, the method includes:

s210, the terminal sends interest information to the first network equipment, wherein the interest information comprises first indication information, and the first indication information is used for indicating whether the terminal is interested in receiving MBS service and unicast service at the same time.

It should be noted that, for whether the terminal supports simultaneous reception of the MBS service and the unicast service, it is currently considered whether the terminal has the capability (capacity) to support simultaneous reception. Based on this, the embodiment of the present application further considers whether the terminals are interested in receiving simultaneously. Therefore, when the terminal reports interest information (interest information or interest message) for the MBS service to the first network device, the first network device can know whether the terminal is interested in receiving the MBS service and the unicast service at the same time through the first indication information in the interest information, so as to ensure that the terminal can receive the MBS service and the unicast service at the same time according to the interest of the terminal, and ensure that the first network device performs resource configuration, resource scheduling, carrier aggregation configuration and the like on the MBS service.

In addition, the first network device may be regarded as a network device described above, such as eNB, gNB, MN, SN, and the like. It can be understood that in the dual connectivity architecture, the terminal may report interest information to the MN or the SN. The MN may be a base station having a control plane connection with a core network; the SN may be a base station with no control plane connection to the core network.

In combination with the above description, the following embodiments of the present application will specifically explain interest information.

In one possible example, the interest information may further include at least one of: the second indication information, the third indication information, the first list and the second list; the second indication information is used for indicating a multiplexing mode for simultaneously receiving the MBS service and the unicast service, wherein the multiplexing mode comprises at least one of space division multiplexing, frequency division multiplexing and time division multiplexing; the third indication information is used for indicating the radio access technology RAT information of the MBS service which the terminal is interested in receiving; the first list is used for representing an MBS service list which is received or is being received by the terminal; the second list is used to represent a frequency list of MBS services that the terminal is interested in receiving.

It should be noted that, in combination with the above description, the interest information sent by the terminal to the first network device in the embodiment of the present application may include at least one of the following:

→ indication information (first indication information) of the MBS service and the unicast service is received at the same time; the simultaneous reception in the embodiment of the present application refers to reception in the same time unit, where the time unit includes one of a frame (frame), a sub-frame (sub-frame), and a slot (slot); the indication information can be used for indicating whether the terminal is interested in or inclined to receive the MBS service and the unicast service simultaneously;

→ indication information (second indication information) of the multiplexing mode of the unicast service of the MBS service is received at the same time; the multiplexing mode in the embodiment of the present application may include (space division multiplexing, SDM), frequency-division multiplexing (FDM), and time-division multiplexing (TDM); the indication information can be used for indicating the multiplexing mode that the terminal is interested in receiving the MBS service and the unicast service simultaneously;

indication information (third indication information) of RAT information of MBS service is → received; the RAT types of the embodiment of the present application may include GSM, CDMA, WCDMA, GPRS, LTE-a, 5G NR, 6G, NTN, 7G, and other radio access technologies; the indication information may be used to indicate RAT information of MBS services that the terminal is interested in receiving; the RAT information is used for representing the RAT required by the MBS service which the terminal is interested in receiving;

→ MBS service list of interest or receiving (first list); in the embodiment of the present application, each MBS service in the MBS service list may be represented by a service identifier, where the service identifier may include a Temporary Mobile Group Identity (TMGI) or an IP address;

→ frequency list (second list) of interested in receiving MBS service; the frequency list may be used to indicate frequencies of MBS services that the terminal is interested in receiving.

Therefore, the network side can know whether the terminal is interested in simultaneously receiving the information of the MBS service and the unicast service, the multiplexing mode, the RAT mode and the like through the terminal reporting the interest information, so that the network side can perform reasonable resource allocation, resource scheduling, carrier aggregation allocation and the like, and ensure that the terminal can simultaneously receive the MBS service and the unicast service according to the interest of the terminal.

In one possible example, the RAT information may include a RAT list or at least one RAT, with the RATs in the RAT list being ordered by priority.

It is understood that the interest information may carry a RAT list or at least one RAT without priority, and the RATs in the RAT list are sorted according to priority. Therefore, the network side can issue MBS service and unicast service which the terminal is interested in according to the RAT information, thereby ensuring the flexibility or diversity of system communication.

For example, the RAT list includes 5G NR, LTE, and 5G NR has higher priority than LTE. Therefore, when the network side receives the RAT list, the network side can preferentially select the 5G NR to send the MBS service and the unicast service that the terminal is interested in.

In one possible example, simultaneous reception refers to reception in the same time unit, the time unit including one of a frame, a subframe, and a slot.

It can be understood that if the MBS service and the unicast service are received in the same frame, subframe or time slot, it means that the MBS service and the unicast service are received simultaneously.

With reference to the above description, the following embodiments of the present application will specifically describe a condition for reporting interest information by a terminal.

In one possible example, the sending, by the terminal, the interest information to the first network device may include: and the terminal sends interest information to the first network equipment under the condition of meeting the reporting condition of the interest aiming at the MBS service.

It should be noted that, in the embodiment of the present application, a condition for reporting the interest of the MBS service by the terminal needs to be considered, so that the terminal is prevented from reporting the interest information anytime and anywhere or when the terminal does not know, thereby reducing signaling overhead and ensuring stability and robustness of system communication.

Specifically, the reporting condition may include at least one of the following conditions:

→ the interest information of the terminal for the MBS service changes; it can be understood that, if the interest information of the terminal for the MBS service changes, the terminal may report new (current) interest information to the first network device, thereby ensuring that the network device knows the new interest information of the terminal in time, and further performing related resource allocation, resource scheduling, and the like in time;

→ the terminal successfully establishes the radio resource control RRC connection; it can be understood that, if the terminal successfully establishes the RRC connection, the terminal may report the interest information to the first network device, so as to ensure that the network device obtains the interest information of the terminal in time, and further perform related resource configuration, resource scheduling, and the like in time;

→ the terminal initiates one of RRC connection establishment, RRC connection reestablishment, RRC connection recovery, RRC connection reconfiguration; it can be understood that, if the terminal initiates an RRC connection (such as RRC connection establishment, RRC connection reestablishment, RRC connection recovery, or RRC connection reconfiguration), the terminal may report the interest information to the first network device, so as to ensure that the network device knows the interest information of the terminal in time, and further perform related resource configuration, resource scheduling, and the like in time;

→ the terminal enters or leaves the zone providing the MBS service; it can be understood that if the terminal enters or leaves the area providing the MBS service, a handover or the like of the network device providing the MBS service is required. Therefore, the terminal can report the interest information to the first network device, so that the network device can be ensured to acquire new (current) interest information of the terminal in time, and relevant resource allocation, resource scheduling, switching decision (switching trigger, target cell selection), second node SN addition (addition) and the like can be performed in time;

→ the MBS service which the terminal is interested in receiving starts or stops issuing; it should be noted that, the first network device may tell in advance when the MBS service that the terminal is interested in receiving starts to be delivered or stops to be delivered (for example, by configuring a timer, by delivering a system message, etc.). Therefore, when the MBS service which the terminal is interested in receiving starts or stops issuing, the terminal may report the interest information to the first network device, thereby ensuring that the network device obtains the interest information of the terminal in time, and further performing related resource allocation, resource scheduling, and the like in time;

→ the relative priority between the MBS service and the unicast service that the terminal is interested in receiving changes; it can be understood that, if the relative priority between the MBS service and the unicast service that the terminal is interested in receiving changes, the terminal may report the interest information to the first network device, so as to ensure that the network device timely knows the new (current) interest information of the terminal, and further timely perform related resource allocation, resource scheduling, and the like;

→ MBS service that the terminal is interested in receiving or receiving changes; it can be understood that, if the MBS service that the terminal is interested in receiving or receiving changes, the terminal may report interest information to the first network device, so as to ensure that the network device obtains new (current) interest information of the terminal in time, and then performs related resource allocation, resource scheduling, and the like in time.

Further, the interest information changes, and may include at least one of the following:

→ there is a change in the interest of whether to receive MBS service and unicast service simultaneously; it can be understood that, if the MBS service and the unicast service do not need to be received simultaneously, the terminal may report the interest information to the first network device;
