In addition, the AAU can realize partial physical layer processing function, radio frequency processing and related functions of the active antenna. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, in this network deployment, higher layer signaling (e.g., RRC layer signaling) may be considered to be transmitted by the DU or transmitted by both the DU and the AAU. It is understood that the network device may include at least one of CU, DU, AAU.

In connection with the above description, before describing in detail the wireless communication method provided by the embodiment of the present application, description will be made of related contents related to the embodiment of the present application.

1. Core network

The core network of the embodiment of the application is composed of core network elements. The core network element may be referred to as a core network device, and is a network element deployed in the core network. For example, a core network control plane network element or a core network user plane network element. The core network of the embodiment of the application can be an evolution type packet core network (evolved packet core, EPC), a 5G core network (5G core network) or a novel core network in a future communication system. For example, the 5G core network is composed of a set of network elements, and implements an access and mobility management function (ACCESS AND Mobility Management Function, AMF) for functions such as mobility management, a user plane function (User Plane Function, UPF) for functions such as packet routing forwarding and QoS (Quality of Service) management, a session management function (Session Management Function, SMF) for functions such as session management, IP address allocation and management, and the like. The EPC may be composed of a Mobility management entity (Mobility MANAGEMENT ENTITY, MME) providing functions of Mobility management, gateway selection, etc., SERVING GATEWAY (S-GW) providing functions of packet forwarding, etc., PDN GATEWAY (P-GW) providing functions of terminal address allocation, rate control, etc. For multicast broadcast service (Multicast Broadcast Service, MBS), the core network may include several new network elements to implement functions such as forwarding of data packets, MBS session management, qoS management, transmission mode switching (switching between unicast and multicast/broadcast transmission modes), etc. Alternatively, the functions may be implemented by an existing core network element.

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, in the embodiment of the present application, the downlink communication 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 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 (multimedia broadcast multicast service, MBMS)

The MBMS service is a service introduced in 3GPP Release 6 (r 6). The MBMS service is a technology for transmitting data from one data source to a plurality of terminals through a shared network resource, and can effectively utilize the network resource while providing a multimedia service, realizing broadcast multicast of the multimedia service at a higher rate (256 kbps).

Because the MBMS spectrum efficiency in 3GPP R6 is low enough to effectively carry the operation of the mobile phone or television type service, in the LTE communication system, 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 (enhanced multimedia broadcast multicast service, E-MBMS) was introduced to the LTE communication system by 3gpp R9. E-MBMS proposes the concept of a single frequency network (single frequency network, SFN), i.e. to transmit data simultaneously in all cells using a unified frequency, but to guarantee synchronization between cells. The method can greatly improve the overall signal-to-noise ratio distribution of the cell, correspondingly and greatly improve the frequency spectrum efficiency, and realize 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).

In summary, for multicast/broadcast service (MBS) services, the transmission mode of the air interface between the network device and the terminal is mainly two of multicast/broadcast and unicast. Since a terminal in a connected state can receive multicast/broadcast traffic from a network device and can also simultaneously receive unicast traffic from the network device in some specific scenarios, further research is required for scenarios in which multiple types of traffic are simultaneously received.

In conjunction with the foregoing description, an embodiment of the present application provides a flowchart of a wireless communication method, referring 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 simultaneously.

It should be noted that, whether a terminal supports simultaneous reception of MBS service and unicast service is currently generally considered whether the terminal has capability (capability) to support simultaneous reception. Based on this, the embodiment of the application further considers whether the terminal is interested in receiving simultaneously. Therefore, when the terminal reports the interest information (InterestInformation or INTERESTMESSAGE) for the MBS service to the first network device, the first network device may learn, through the first indication information in the interest information, whether the terminal is interested in receiving the MBS service and the unicast service simultaneously, thereby ensuring that the terminal can receive the MBS service and the unicast service simultaneously according to its own interest, and ensuring that the first network device performs resource allocation, resource scheduling, carrier aggregation allocation, and the like for transmitting the MBS service.

In addition, the first network device may be considered a network device as described above, such as eNB, gNB, MN, SN, etc. It will be appreciated that in a dual connectivity architecture, the terminal may report interest information to the MN or SN. The MN may be a base station connected to a control plane of the core network, and the SN may be a base station connected to a control plane of the core network.

In conjunction with the foregoing description, the following embodiments of the present application will specifically describe interest information.

In one possible example, the interest information may further include at least one of second indication information, third indication information, a first list and a second list, where the second indication information is used to indicate a multiplexing manner of receiving the MBS service and the unicast service simultaneously, the multiplexing manner includes at least one of space division multiplexing, frequency division multiplexing and time division multiplexing, the third indication information is used to indicate radio access technology RAT information of the MBS service that the terminal is interested in receiving, the first list is used to indicate the MBS service list that the terminal is interested in receiving or is receiving, and the second list is used to indicate a frequency list of the MBS service that the terminal is interested in receiving.

It should be noted that, in connection 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:

The simultaneous reception of the embodiment of the application refers to the reception in the same time unit, wherein the time unit comprises one of a frame, a sub-frame and a slot (slot), and the indication information can be used for indicating whether a terminal is interested in or tends to simultaneously receive the MBS service and the unicast service;

The multiplexing mode of the embodiment of the application can comprise (space division multiplexing, SDM), frequency Division Multiplexing (FDM) and time division multiplexing (time-division multiplexing, TDM), wherein the indicating information can be used for indicating the multiplexing mode of the terminal interested in receiving the MBS service and the unicast service simultaneously;

The RAT type of the embodiment of the application can comprise GSM, CDMA, WCDMA, GPRS, LTE, LTE-A, 5G NR, 6G, NTN, 7G and other wireless access technologies, the indication information can be used for indicating the RAT information of the MBS service which the terminal is interested in receiving, and the RAT information is used for indicating the RAT which the terminal is interested in receiving and is required to be adopted by the MBS service;

The MBS service list (first list) which is interested in receiving or is receiving, wherein the embodiment of the application can represent each MBS service in the MBS service list through a service identifier, and the service identifier can comprise a temporary mobile group identifier (temporary mobile group identity, TMGI) or an IP address and the like;

a frequency list (second list) of MBS services of interest to be received, which may be used to represent frequencies of MBS services of interest to be received by the terminal.

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

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

It is to be appreciated that the interest information can carry a list of RATs or at least one RAT without prioritization, and that each RAT in the list of RATs is prioritized. Therefore, the network side can issue MBS service and unicast service which are interested by the terminal 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 may preferentially select 5G NR to deliver MBS services and unicast services of interest to the terminal.

In one possible example, simultaneous reception refers to reception in the same time unit, which includes 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.

In combination with the above description, the following embodiments of the present application specifically describe conditions for reporting interest information by a terminal.

In one possible example, the terminal sending the interest information to the first network device may include the terminal sending the interest information to the first network device under reporting conditions that satisfy the interest for the MBS service.

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

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

it can be understood that if the terminal changes the interest information of the MBS service, the terminal can report new (current) interest information to the first network equipment, thereby ensuring that the network equipment timely acquires the new interest information of the terminal and further timely performs relevant resource allocation, resource scheduling and the like;

If the terminal successfully establishes the RRC connection, the terminal can report interest information to the first network equipment, thereby ensuring that the network equipment timely acquires the interest information of the terminal and further timely performs relevant resource configuration, resource scheduling and the like;

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 can report interest information to the first network device, thereby ensuring that the network device can acquire the interest information of the terminal in time and further perform relevant resource configuration, resource scheduling and the like in time;

It can be understood that if the terminal enters or leaves the MBS service providing area, a handover or the like is required for the network device providing the MBS service. Therefore, the terminal can report the interest information to the first network device, thereby ensuring that the network device timely acquires the new (current) interest information of the terminal, and further timely performing relevant resource configuration, resource scheduling, switching decision (switching trigger, target cell selection), second node SN addition (addition) and the like;

The first network device tells the terminal when to start or stop transmitting the MBS service (such as by configuring a timer, transmitting by a system message, etc.) interested in receiving. Therefore, when the MBS service which is interested in being received by the terminal starts or stops issuing, the terminal can report the interest information to the first network equipment, thereby ensuring that the network equipment timely acquires the interest information of the terminal, and further timely carrying out relevant resource allocation, resource scheduling and the like;

if the relative priority between the MBS service and the unicast service which the terminal is interested in receiving changes, the terminal can report the interest information to the first network equipment, thereby ensuring that the network equipment can acquire the new (current) interest information of the terminal in time, and further carrying out relevant resource allocation, resource scheduling and the like in time;

it can be understood that if the terminal is interested in receiving or receiving the MBS service and the MBS service is changed, the terminal can report the interest information to the first network device, thereby ensuring that the network device timely knows the new (current) interest information of the terminal and further timely performs relevant resource allocation, resource scheduling and the like.

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

If the MBS service and the unicast service are not required to be received at the same time, the terminal can report the interest information to the first network equipment;

It can be understood that if the receiving of the MBS service and the unicast service in the same frame is changed to the receiving of the MBS service and the unicast service in the same time slot, the terminal can report the interest information to the first network device;

if the multiplexing mode of receiving MBS service and unicast service at the same time is changed from time division multiplexing to frequency division multiplexing, the terminal can report interest information to the first network equipment;

It can be understood that if the RAT information includes a RAT list, and the number of RATs in the RAT list is changed, or the priority ranking order among RATs in the RAT list is changed, the terminal can report the interest information to the first network device.

In combination with the above description, the manner in which the interest information is transmitted or carried will be specifically described in the following embodiments of the present application.
