Embodiment Construction

[0065] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0066] MBMS is a typical service of the LTE system in the 3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) protocol, and the service can be broadcast in an LTE cell through the MBMS bearer. Specifically, there are two ways to broadcast MBMS through MBMS: one is to broadcast MBMS by means of Multimedi...

Abstract

Embodiments of the present invention provide a method, apparatus, and device for sending scheduling information of multimedia broadcast and multicast services, including: determining a control resource set and a search space corresponding to a physical downlink control channel PDCCH, where the PDCCH is used to carry a multimedia broadcast and multicast service MBMS Scheduling information; according to the control resource set and the search space, allocate air interface resources to the PDCCH; send the PDCCH through the allocated air interface resources, and the PDCCH carries MBMS scheduling information. The above method realizes that MBMS scheduling information is broadcast in the NR cell, and the UE receives the corresponding MBMS according to the MBMS scheduling information.

Description

technical field [0001] Embodiments of the present invention relate to the field of communications, and in particular, to a method, apparatus and device for sending scheduling information of multimedia broadcast and multicast services. Background technique [0002] The Multimedia Broadcast Multicast Service (MBMS) is a typical service of the LTE system in the 3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) protocol, and the service can be broadcast in an LTE cell through the MBMS bearer. Specifically, there are two ways to broadcast MBMS through MBMS: one is to broadcast MBMS in a Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) mode; the other is to use a single cell point to Multipoint (Single Cell Point to Multipoint, SC-PTM for short) mode broadcasts MBMS. In order to enable the UE to receive the MBMS broadcast in the SC-PTM manner in the LTE cell, the scheduling information of the MBMS needs to be broadcast in the...
