Embodiment 1

[0038] The method for 5G NR supporting cluster broadcast message transmission of the present invention includes the following steps:

[0039]S100, adding a trunk-SearchSpace information element to the PDCCH-ConfigCommon information element to add an exclusive cluster service search space for the cluster service;

[0040] S200, specify that the trunk-SearchSpace cell is an optional IE.

[0041] The trunk-SearchSpace cell type is SearchSpaceId. The function of the trunk-SearchSpace cell is to indicate the CORESET and Search Space configuration exclusive to the trunking service through its corresponding SearchSpaceId.

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

[0043] Specifies that trunk-SearchSpace is an optional IE, and SearchSpace0 is used by default if it is not configured. That is, when trunk-SearchSpace is not configured, use CORESET0 and Search Space0.

[0044] The 5G NR standard protocol stipulates that the search space ...

Embodiment 2

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

[0055] And the trunk-SearchSpace cell has the following requirements:

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

[0057] (2) Each cell sending 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 the cluster service, the services are synchronously scheduled among the cells.

[0059] Wherein, the trunk-SearchSpace information element type is SearchSpaceId; the trunk-SearchSpace information element is used to indicate the dedicated CORESET and Search Space confi...

Embodiment 3

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

Abstract

The invention discloses a method, system and device for 5G NR to support cluster broadcast message sending, belonging to the technical field of 5GNR system cluster broadcast technology, and the technical problem to be solved is how to realize the support of 5GNR to the cluster service function. The method is to add a trunk-SearchSpace information element in the PDCCH-ConfigCommon information element to add a dedicated trunk-SearchSpace information element for the trunking service; and specify that the trunk-SearchSpace information element is an optional IE. It can effectively solve the problem that the 4G broadband trunking system cannot support the typical application scenarios of 5G, so that the broadcast message sending of the trunking service can be better supported on the 5G NR system.

Description

technical field [0001] The present invention relates to the technical field of 5G NR system cluster broadcasting, in particular to a method, system and device for 5G NR to support cluster broadcasting message sending. Background technique [0002] The wireless broadband trunking system is developed to meet the command and dispatch requirements of industry users, and is a dedicated wireless communication system for specific industry applications. In recent years, wireless broadband trunking communication systems have a wide range of application markets in government and enterprise private networks, public safety, emergency communications, rail transit, electric power, civil aviation, petrochemicals, and the military. The development of trunking communication system has experienced 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 wireless broadband t...
