Embodiment 1

[0038] 5G NR of the present invention supports the method for cluster broadcast message transmission, comprising the following steps:

[0039]S100, adding a trunk-SearchSpace information element in the PDCCH-ConfigCommon information element, adding a dedicated trunking service search space for the trunking service;

[0040] S200. It is specified that the trunk-SearchSpace information element is an optional IE.

[0041] Among them, the trunk-SearchSpace cell type is SearchSpaceId. The role of the trunk-SearchSpace IE is to indicate the cluster service-specific CORESET and Search Space configuration through its corresponding SearchSpaceId.

[0042] The syntax is described as "trunk-SearchSpace SearchSpaceId OPTIONAL,--Need S".

[0043] It is stipulated that trunk-SearchSpace is optional IE, and SearchSpace0 is used by default if there is no configuration. That is, when trunk-SearchSpace is not configured, use CORESET0 and Search Space0.

[0044] The 5G NR standard protocol s...

Embodiment 2

[0054] The 5G NR of the present invention supports a system for sending trunk broadcast messages. A trunk-SearchSpace cell is added to the PDCCH-ConfigCommon cell of the NR system, and a dedicated trunk service search space is added for the trunk service through the trunk-SearchSpace cell.

[0055] And the trunk-SearchSpace IE has the following provisions:

[0056] (1) It is stipulated that the trunk-SearchSpace cell is an optional IE;

[0057] (2) Each cell that sends the cluster service adopts the same time-frequency resource configuration for the trunk-SearchSpace resource of the cluster service;

[0058] (3) When the trunk-SearchSpace resource schedules cluster services, the services are scheduled synchronously among the cells.

[0059] Wherein, the type of the trunk-SearchSpace information element is SearchSpaceId; the trunk-SearchSpace information element is used to indicate the cluster service-specific CORESET and Search Space configuration through its corresponding Se...

Embodiment 3

[0063] An embodiment of the present invention also provides a device, including: at least one memory and at least one processor; the at least one memory is used to store a machine-readable program; the at least one processor is used to call the machine-readable program , execute the method disclosed in Embodiment 1 of the present invention.

Abstract

The invention discloses a method, a system and a device for supporting sending of a cluster broadcast message by 5G NR, belongs to the technical field of cluster broadcast of a 5GNR system, and aims to solve the technical problem of how to realize support of 5GNR to a cluster service function. The method comprises the following steps of: adding a trunk-SearchSpace cell in a PDCCH (Packet Data Control Channel)-ConfigCommon cell, and adding an exclusive cluster service search space for a cluster service; and stipulating that the trunk-SearchSpace cell is an optional IE (Internet Explorer). The problem that a 4G broadband trunking system cannot support a 5G typical application scene can be effectively solved, and broadcast message sending of a trunking service can be well supported on a 5G NR system.

Description

technical field [0001] The present invention relates to the technical field of 5G NR system trunking broadcasting, in particular to a method, system and device for 5G NR supporting trunking broadcasting message transmission. Background technique [0002] The wireless broadband trunking system is developed to meet the command and dispatch needs of industry users, and is a dedicated wireless communication system for specific industry applications. In recent years, the wireless broadband trunking communication system has a wide range of application markets in the fields of government and enterprise private networks, public security, emergency communications, rail transit, electric power, civil aviation, petrochemicals, and the military. The development of trunking communication system has gone through the first generation of analog trunking communication system and the second generation of narrowband digital trunking communication system, and has now developed to the stage of w...
