Embodiment 1

[0227] In this example, the terminal reports the interested MBS service through the random access request (Msg1) (the random access ends in Msg2).

[0228] Figure 10 It is a schematic diagram of the reporting process of the interested MBS service in Embodiment 1, as shown in the figure, and will be described from both sides of the terminal and the base station respectively.

[0229] Terminal side:

[0230] 1: When triggering the reporting of the interested MBS service, select the PRACH resource corresponding to the interested MBS service and send the configured preamble code. If there are multiple interested MBS services corresponding to different random access resources, the terminal decides first Which one to send;

[0231] 2: Calculate the RA-RNTI according to the time-frequency position of the PRACH resource used in 1, and use the RA-RNTI to receive the base station downlink scheduling command PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel),...

Embodiment 2

[0241] In this example, the terminal reports the interested MBS service through the random access request (Msg1) (the random access process ends in Msg4).

Embodiment 3

[0260] In this example, the 2-step RACH is used to realize the reporting of the interested MBS service.

[0261] Embodiment 3 may correspond to Embodiment 2, and Embodiment 1 does not need to use 2-step RACH.

[0263] Terminal side:

[0264] 1: MSGA includes PRACH resources for sending preamble codes and PUSCH resources for sending uplink data transmission. When triggering the reporting of the interested MBS service, select the PRACH resource corresponding to the interested MBS service to send the configured preamble code. If there are multiple interested MBS services corresponding to different rando...

Abstract

The invention discloses a multicast broadcast service interest reporting and determining method, equipment and a medium. The method comprises the step that a terminal reports an interested multicast broadcast service to a base station through a random access process; and the base station determines the multicast broadcast service in which the terminal is interested according to the multicast broadcast service in which the terminal is interested. By adopting the method, the defect that a scheme for reporting the information interested in the multicast broadcast service by the terminal of the 5G system does not exist at present is overcome, the reporting of the interest of the terminal in the multicast broadcast service can be effectively realized, and a base station can carry out reasonable processing. Furthermore, the scheme is suitable for a connected terminal and an idle/inactive terminal at the same time, and universal design is realized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and medium for reporting and determining interest in a multicast broadcast service. Background technique [0002] The MBMS (multicast broadcast multimedia service, multimedia broadcast multicast service) service has existed for a long time in 3G and 4G technologies. figure 1 It is a schematic diagram of an MBMS transmission architecture based on MBSFN (Multimedia Broadcast multicast service Single Frequency Network) in LTE (Long Term Evolution). [0003] Due to the requirements of broadcast and multicast services, 5G technology will soon introduce MBMS services in R17 (version 17), which is called MBS (Multicast and Broadcast Services, Multicast and Broadcast Services) in 5G. However, there is no need to introduce the MBSFN architecture in 5G, and each cell sends MBS services independently. figure 2 It is a schematic diagram of MBS servi...
