Technical Field

Optionally, the multicast broadcast configuring method further includes:

The following describes a specific implementation procedure of the multicast broadcast configuration method according to the present invention with reference to a specific embodiment.

Example one

As shown in fig. 5, the configuration and transmission process of the multicast broadcast configuration information is illustrated in the first embodiment. Specifically, taking a cell in which a terminal is currently located as a first base station, a neighboring base station of the first base station as a second base station, and a multicast broadcast control node as an MCE as an example, an implementation process of configuring and sending multicast broadcast configuration information includes:

s510, the MCE sends request information for acquiring the multicast broadcast auxiliary information to each base station (in this embodiment, including the first base station and the second base station);

s520, the first base station and the second base station which receive the request information respond to the request information and send multicast broadcast auxiliary information to the MCE; specifically, the multicast broadcast auxiliary information includes the contents listed in the above description, which are not described herein again;

s530, the MCE determines which multicast broadcast services are broadcast on which BWP and/or beam based on the multicast broadcast auxiliary information sent by each base station, generates multicast broadcast configuration information corresponding to each base station, and sends corresponding multicast broadcast configuration information to each base station;

s540, the first base station sends a multicast broadcast configuration information request to the second base station;

s550, responding to the multicast broadcast configuration information request, the second base station sends the multicast broadcast configuration information on the second base station to the first base station;

s560, the first base station sends the multicast broadcast configuration information of the first base station and/or the second base station to the terminal through the system information or the RRC dedicated signaling.

In step S560, when the multicast broadcast configuration information of the first base station and/or the second base station is transmitted to the terminal through the system information, the transmission manner of the multicast broadcast configuration information is applicable to all terminals under the coverage of the first base station. After receiving the system information, the terminal may read the corresponding multicast broadcast service on the BWP or the beam configured by the multicast broadcast configuration information.

In step S560, when the multicast broadcast configuration information of the first base station and/or the second base station is transmitted to the terminal through the RRC dedicated signaling, the transmission mode of the multicast broadcast configuration information is applicable to the handover scenario; the first base station can send the multicast broadcast configuration information of the second base station to the terminal through the RRC reconfiguration message; or, the sending mode of the multicast broadcast configuration information is suitable for a connected terminal, and the first base station sends the multicast broadcast configuration information of the first base station and/or the second base station to the terminal through an RRC dedicated signaling, so that the terminal reads a corresponding multicast broadcast service through the first base station and/or the second base station.

Of course, in step S540 and step S550, the second base station may also send a multicast broadcast configuration information request to the first base station to obtain the multicast broadcast configuration information on the first base station.

Through the above steps S540 and S550, the multicast broadcast configuration information may be interacted between the first base station and the second base station through the inter-base station interface, so that the first base station obtains the multicast broadcast configuration information on the second base station, and can send the multicast broadcast configuration information on the second base station to the terminal to be switched to the second base station. In this way, after the terminal is handed over from the first base station to the second base station, the terminal may read the corresponding multicast broadcast service on the corresponding BWP or beam according to the multicast broadcast configuration information of the second base station acquired from the first base station without requesting the multicast broadcast configuration information from the second base station.

Example two

This second embodiment illustrates a specific manner in which the terminal receives the multicast broadcast service according to the multicast broadcast configuration information.

In the second embodiment, as shown in fig. 6, the multicast broadcast configuration information acquired by the terminal includes the following contents:

the first multicast broadcast service is indicated to be broadcast on BWP ID #1 and beam ID #0/1/2/3, the multicast broadcast period is 40ms, and the offset of the multicast broadcast period is 0 ms;

the second multicast broadcast service is indicated to be broadcast on BWP ID #1 and beam ID #4/5, the multicast broadcast period is 80ms, and the offset of the multicast broadcast period is 40 ms;

the third multicast broadcast service is instructed to be broadcast on BWP ID #2 and beam ID #4/5, with a multicast broadcast period of 160ms and an offset of 0 ms.

Based on the multicast broadcast configuration information received by the terminal, when the terminal desires to receive the first multicast broadcast service, it needs to switch to BWP ID #1 at the first time and receive the first multicast broadcast service on multicast broadcast beam ID # 0/1/2/3.

Specifically, the first time is determined by SFN mod T ═ FLOOR (offset/10);

where T is a multicast broadcast period of the first multicast broadcast service, offset is an offset of the multicast broadcast period, which corresponds to 0ms in this embodiment, SFN represents a first time, Floor () represents a down-rounding function, and mod represents a remainder function. As can be seen from the above data calculation, when the system frame number (first time) is SFN 0, 4, and 8 …, the terminal needs to switch to BWP ID #1 and receive the first multicast broadcast service on multicast broadcast beam ID # 0/1/2/3.

When the terminal desires to receive the third multicast broadcast service, it needs to switch to BWP ID #3 at the second time and receive the third multicast broadcast service on multicast broadcast beam ID # 4/5.

Likewise, the second time is determined by SFN mod T ═ FLOOR (offset/10).

Where T is a multicast broadcast period of the third multicast broadcast service, offset is an offset of the multicast broadcast period, which corresponds to 0ms in this embodiment, SFN represents the second time, Floor () represents a down-rounding function, and mod represents a remainder function. As can be seen from the above data calculation, the terminal needs to switch to BWP ID #1 and receive the third multicast broadcast service on multicast broadcast beam ID #4/5 when the system frame number (second time) is SFN 0, 16, and 32 ….

EXAMPLE III

The third embodiment illustrates a specific process of the terminal switching to receive the multicast broadcast service on different BWPs.

In the third embodiment, the multicast broadcast configuration information acquired by the terminal includes the following contents:

the first multicast broadcast service is indicated to be broadcast On BWP ID #1, the multicast broadcast period is 40ms, the duration On duration of multicast broadcast service transmission is 10ms, and the timing duration of a BWP inactivity timer is 5 ms;

the second multicast broadcast service is instructed to be broadcast On BWP ID #2, the multicast broadcast period is 80ms, the duration On duration of the multicast broadcast service transmission is 10ms, and the timing duration of the BWP inactivity timer is 5 ms.

As shown in fig. 7, it is assumed that the UE is currently operating on BWP ID #3 and desires to receive the first multicast broadcast service and the second multicast broadcast service.
