Problems solved by technology

Since the G-RNTI value is related to the candidate PDCCH group-specific search space, if the G-RNTI allocated for the cluster group is calculated and the candidate PDCCH search space completely overlaps with the common search space, PDCCH resource collision will occur, resulting in group Calls cannot be dispatched in time due to the inability to send DCI, and the transmission efficiency of trunk group call downlink data decreases

Embodiment Construction

[0053] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0054] The first embodiment of the present invention provides a method for allocating a group call RNTI of a cluster group, such as figure 1 shown, including:

[0055] Step S1, obtain the RNTI configuration table of the cluster group, wherein the RNTI configuration table includes: a first RNTI set and a second RNTI set, and the group-specific search indicated by any RNTI value in the first RNTI set There is no resource overlap between the space and the public search space, and the overlapping amount of the group-specific search space indicated by any RNTI value in the second RNTI set and a preset type of resource in the public search space does not exceed a preset th...

Abstract

The present invention relates to the field of communication technologies, and in particular to a method and system for allocating group call RNTIs of trunk groups. The method includes: obtaining an RNTI configuration table of the cluster group, the RNTI configuration table including: a first RNTI set and a second RNTI set, and a group-specific search space indicated by any RNTI value in the first RNTI set There is no resource overlap with the public search space, and the overlapping amount of the group-specific search space indicated by any RNTI value in the second RNTI set and a preset type of resource in the public search space is less than a preset threshold; when the second When there is an unoccupied RNTI value in an RNTI set, select the RNTI value from the first RNTI set as the G-RNTI of the cluster group, otherwise, select the RNTI value from the second RNTI set as the G-RNTI of the cluster group The G‑RNTI for the cluster group described above. The method for allocating group call RNTI of trunk group provided by the present invention can effectively reduce the probability of PDCCH scheduling collision and improve the efficiency of allocating RNTI for group call of trunk group.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method and system for allocating group call RNTIs of trunk groups. Background technique [0002] With the rapid development of social economy and changes in the needs of industry customers, TD-LTE broadband trunking with large bandwidth, high speed, all-IP, efficient command and control and real-time response capabilities will lead the trunking communication into a new era. The private network broadband multimedia trunking technology is closely combined with industry applications to promote the continuous improvement and rapid development of the TD-LTE broadband trunking communication system in the industry. China Communications Standards Association (CCSA) led the completion of the TD-LTE broadband cluster communication industry standard, which is also the first batch of industry standards based on 4G technology cluster in China. [0003] The trunking group...
