Abstract

Description

Method, equipment and medium for reporting and determining interest of multicast broadcast service

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method, a device, and a medium for reporting and determining multicast broadcast service interest.

Background

MBMS (multicast broadcast multimedia service) services have long existed in 3G, 4G technologies. Fig. 1 is a schematic diagram of an MBMS transmission architecture based on MBSFN (multicast Broadcast Single Frequency Network) in LTE (Long Term Evolution).

Due to the demand of Broadcast Multicast Services, the 5G technology is also about to introduce MBMS Services in R17 (release 17), which is called MBS (Multicast and Broadcast Services) in 5G. However, the 5G does not need to introduce an MBSFN architecture, and each cell independently transmits MBS services. Fig. 2 is a schematic diagram of MBS service transmission, and a data transmission flow of the MBS service is shown in fig. 2.

Because resources in a cell are limited, a base station needs to accurately control MBS service transmission, but the prior art cannot accurately control the MBS service transmission, and resource waste is inevitably caused.

The prior art is deficient in that there is no method for reporting information interested in MBS service for a terminal of a 5G system.

Example 1:

in this example, the MAC CE reporting the interested MBS service includes an MBS service number, and the receiving MBS service and the interested MBS service are fed back in a unified manner.

MBS service number corresponds to: the sequence of MBS service in the base station configuration message; or MBS ID explicitly configured by the base station. Taking the number of MBS services with the maximum feedback interest as an example, the MBS ID length is 4 bits.

Fig. 5 is a schematic diagram of a MAC CE format inembodiment 1, and fig. 6 is a schematic diagram of a MAC subheader format with a length indication field inembodiment 1, as shown in the figure, the MAC CE inembodiment 1 is variable in length, and the format thereof is as shown in fig. 5, and the corresponding MAC subheader with the length indication field is as shown in fig. 6.

Example 2:

in this example, the MAC CE reporting the MBS service of interest indicates the MBS service with bitmap, and the MBS service being received and the MBS service of interest are fed back in a unified manner.

The Bitmap represents the corresponding MBS business according to the configuration sequence of the MBS business in the base station configuration message or the size sequence of the MBS ID explicitly configured by the base station. Taking the maximum feedback interested MBS service number as 16 as an example, the bitmap length is 2 byte.

Fig. 7 is a diagram of the MAC CE format ofembodiment 2, and fig. 8 is a diagram of the MAC subheader format without the length indication field ofembodiment 2, as shown in the figure, the MAC CE ofembodiment 2 is of fixed length, and its format is as shown in fig. 7, and the corresponding MAC subheader without the length indication field is as shown in fig. 8.

Example 3:

in this example, the MAC CE reporting the interested MBS service includes an MBS service number, and the currently received MBS service and the interested MBS service are expressed in a differentiated manner.

MBS service number corresponds to: the sequence of MBS service in the base station configuration message; or MBS ID explicitly configured by the base station. Taking the number of the services with the maximum feedback MBS interest as an example, the MBS ID length is 4 bits.

Fig. 9 is a schematic diagram of a MAC CE format according to embodiment 3, and as shown in the drawing, in an example of the MAC CE format according to embodiment 3, the MAC CE is variable in length, and a corresponding MAC sub-header length indication field is shown in fig. 6. In the MAC CE format, Nreceiving (receiving) indicates the number of MBS services being received, and then the MBS IDs being received are arranged first, and after the arrangement, the MBS IDs of the MBS services that are interested but not yet received are arranged.

Example 4:

in this example, the MAC CE reporting the MBS service of interest indicates the MBS service by bitmap, and the MBS service being received and the MBS service of interest are expressed separately.

Taking the number of the services with the maximum feedback MBS interest as an example, the bitmap length is 2 byte.

2: receiving an MAC CE which is sent by a terminal and used for reporting an interested MBS service;

3: according to the MBS service transmission situation, there may be the following branches:

if the MBS service is in multicast transmission, the base station can count based on the MAC CE which is sent by the terminal and reports the interested MBS service, thereby determining whether to continue to adopt the multicast mode to transmit the MBS service, in addition, if the base station can determine that the terminal is interested in the MBS service but does not receive the MBS service before, the base station can send the receiving parameter (such as G-RNTI) of the MBS service to the terminal;

if the MBS service is supported by the cell but not multicast-transmitted, the base station can start to multicast-transmit the MBS service according to the request of the terminal and inform the terminal of the multicast-transmitted parameters (such as G-RNTI, etc.) of the MBS service;

if the MBS service is not supported by the cell but supported by the same coverage cell or frequency point, the base station can initiate a switching process to the connected terminal.
