The following first describes what the scheme provided by the embodiment of the present application relates to.

1. 5G network architecture

In the 5G network architecture, taking 5G/NR as an example, the part closely related to the air interface is shown in FIG. 1. In NR and similar systems, a logical radio access network node (RAN node) may be further divided into a Control Plane center node (CU-CP), one or more User Plane center nodes (CU-UP), and one or more Distributed Units (DU), which is referred to as a "CU-CP/UP split (CU-CP/UP split)". The CU-CP and DU are connected by F1-C or the like, and the CU-CP and CU-UP are connected by E1 or the like. The control plane connection of the RAN node with the core network/other NG-RAN nodes ends at CU-CP, the user plane connection ends at CU-UP, and the air interface connection of the RAN node with the mobile terminal ends at DU.

The gNB-CU-CP refers to the Control Plane part of the Central Unit in gNB, which is the most core module in gNB, and is connected to AMF via N2 interface (also called NG-C interface in this case, i.e. Control Plane part in NG interface). Two adjacent gNBs are connected through an Xn interface. Each UE may be connected to multiple gNB-CU-CPs at the same time, but only one of them is the primary gNB-CU-CP, with an N2 context associated with the UE between itself and the AMF. Different gNB-CU-CPs are connected through an Xn-C interface. The gNB-CU-CP maps one or more QoS flows in each session into one radio bearer for air interface transmission according to its own policy. The gNB-CU-CP is also responsible for sending RRC (Radio Resource Control ) messages to the UE to indicate how it configures the air interface link. These message RRC messages are sent and received through the PDCP (Protocol Data Unit, packet data convergence protocol) layer.

gNB-CU-UP refers to the User Plane section in the Central Unit Central Unit in gNB. The gNB-CU-CP manages the gNB-CU-UP through an E1 interface, for example, requests the gNB-CU-UP to establish, modify and release a transmission channel of service data. In principle, gNB-CU-UP interacts traffic data with UPF via N3 interface north and gNB-DU via F1-U interface south.

gNB-DU refers to Distributed units among gNBs. gNB-CU-CP manages gNB-DU through F1-C interface, for example, requests gNB-DU to build, modify and release air interface resource. The gNB-DU mainly includes RLC (Radio Link Control ), MAC (Media Access Control, medium Access control), PHY (Physical ) and RF (Radio Frequency) layers.

2. Unicast, broadcast and multicast

A variety of communication modes are supported in wireless networks, including unicast, broadcast and multicast. Unicast is the network allocates dedicated radio resources for services supported by a particular UE and informs the UE that only the UE can send and receive data on that portion of radio resources. Most of the traffic of the UE, such as voice, data, etc., belongs to this class of traffic. The broadcasting is that the network side transmits downlink data on a radio resource carrying a certain broadcasting service, all UEs can receive the service on the radio resource, and the network side informs the UE of the update of the configuration information of the radio resource through a system message. Broadcast services may be used for public safety information dissemination such as weather pre-warning and the like. The multicast service is a process that the network side provides the same service for a plurality of UEs at the same time, and if the UE is to accept the service, the UE must have a procedure of requesting to join to the network side. The multicast service can be applied to scenes such as stadiums, remote education and the like.

Currently, if a UE is receiving both broadcast/multicast service and unicast service, since unicast service and broadcast/multicast service may be provided by different cells, different cells may schedule unicast service and broadcast/multicast service on the same time-frequency resource at the same time. In this case, there is no way for a UE that is not capable of accepting both services on the same time-frequency resource to make unicast or broadcast/multicast services.

Based on the above, the embodiments of the present application provide a resource scheduling method, apparatus, device, terminal and network element, so as to solve the problem in the prior art that resource conflict is easy to occur due to unclear resource scheduling information of a neighboring cell in a cell.

Referring to fig. 2, an embodiment of the present application provides a resource scheduling method applied to a first network element, where the first network element may be a first network device, such as a first base station, or a distribution Unit of the first network device, such as a Distributed Unit (DU) in the first base station, and the method includes the following steps:

step 201, obtaining first resource information corresponding to a first broadcast multicast service, wherein the first resource information is resource information allocated to the first broadcast multicast service by a neighboring cell;

And 202, performing resource scheduling according to the first resource information.

In this embodiment, the first network element can perform resource scheduling based on the first resource information of the first broadcast multicast service by acquiring the first resource information corresponding to the first broadcast multicast service currently supported by the neighboring cell, so as to avoid the problem that the first network element collides with the first resource information when performing resource scheduling.

The following description of step 201 mainly includes the following five ways:

And step two, gNB1 receives and stores the third resource information sent by gNB2, and responds to the NG-RAN node configuration update ACK message for gNB 2.

Step three, gNB1 receives service information (identification information of a first broadcast multicast service) which is sent by UE and is of interest to the user;

and step four, the gNB1 determines first resource information corresponding to the first broadcast multicast service according to the identification information of the first broadcast multicast service and the second resource type information.

Mode two

Step one, the gNB2 sends the identification information of the broadcast or multicast service supported by the serving cell under the own base station to the gNB1 through an interface message.

And step two, the gNB1 receives and stores the identification information of the broadcast or multicast service, and responds to the NG-RAN node configuration update ACK message to the gNB 2.

And step three, the gNB1 receives service information (identification information of a first broadcast multicast service) which is sent by the UE and is interested in the gNB.

Step four, the gNB1 requests the gNB2 for resource information (first resource information) of the broadcast or multicast service that is of interest to the UE.

Step five, the gNB2 sends the first resource information to the gNB1 based on the request of the gNB1.

It should be noted that, the first and second modes apply to the first network element as the first network device; the second network element is in a scenario of the second network device.

Mode three

In one embodiment, step 201 includes:

Illustratively, as shown in fig. 5, in the scenario where CU and DU of the first base station are separated, the first network element is a distribution unit (gNB 1-DU) of the first base station, and the second network element is a central unit (gNB 1-CU) of the first base station. Specifically, the method may include the steps of:

step one, the gNB2 (second network device) sends resource information (third resource information) of the broadcast or multicast service supported by the serving cell under the own base station to the gNB1-CU through an interface message.

And step two, the gNB1-CU receives and stores the third resource information, and responds to the NG-RAN node configuration update ACK message to the gNB 2.

Step three, the UE informs the gNB1-CU of the service information (the identification information of the first broadcast multicast service) of the broadcast/multicast service of interest by itself through the RRC message.

And step four, the gNB1-CU informs the gNB1-DU of the third resource information of the broadcast or multicast service of interest to the UE.

Mode four

Specifically, the method may include the steps of:

Step one, the gNB2 (second network device) sends resource information (third resource information) of the broadcast or multicast service supported by the serving cell under the own base station to the gNB1-CU (second network element) through an interface message.

Step two, the gNB1-CU responds to the NG-RAN node configuration update ACK message to the gNB 2.

And thirdly, the gNB1-CU stores resource information (third resource information) of broadcast/multicast service of the cell under the gNB 2.

And step four, the UE informs the gNB1-CU of the identification information of the broadcast/multicast service of interest by itself through the RRC message.

And fifthly, the gNB1-CU informs the gNB1-DU of the broadcast/multicast service of interest to the UE and the resource information (first resource information) corresponding to the service.

Illustratively, in the scenario where CU and DU of the first base station are separated as shown in fig. 7, the first network element is a distribution unit (gNB 1-DU) of the first base station, and the second network element is a central unit (gNB 1-CU) of the first base station. The terminal (UE) directly reports the resource information of the first broadcast multicast service of interest to the gNB1-CU, and the gNB1-CU sends the resource information of the first broadcast multicast service of interest to the terminal to the gNB1-DU.

It should be noted that, the third and fourth modes are specifically applied to a scenario in which the first network element is a distribution unit DU in the network device, the second network element is a central unit CU in the network device, and the first network element and the second network element are separated.

In the embodiments of the first to fourth modes, by determining the first resource information corresponding to the first broadcast multicast service, when the unicast service of the UE is scheduled, resource conflict with the broadcast or multicast service (the first broadcast multicast service) currently supported by the neighboring cell of interest of the UE can be avoided, and the terminal can receive the unicast service and the broadcast or multicast service at the same time.

Further, in one embodiment, step 202 includes:

In this embodiment, the first network element can avoid the transmission resource of the first broadcast multicast service when scheduling the resources by acquiring the first resource information corresponding to the first broadcast multicast service currently supported by the neighboring cell, so as to avoid the problem that the first network element collides with the transmission resource of the first broadcast multicast service when scheduling the resources.

Specifically, the first network element selects second resource information corresponding to unicast service for the terminal; wherein the second resource information does not overlap with the first resource information.

The first resource information in this embodiment may be resource information of a first broadcast multicast service that the terminal is interested in or is receiving.

In the above embodiment, when the first network element schedules unicast service resources for the terminal, the transmission resources of the first broadcast multicast service currently supported by the cell adjacent to the first network element are avoided, so that the problem of conflict between unicast service and broadcast or multicast service in resource use is avoided, and the terminal can accept unicast and broadcast or multicast services simultaneously.

It should be noted that the first resource information, the second resource information, and the third resource information include at least one of the following: frequency point information, subcarrier spacing and bandwidth information.
