Allotment of radio resources in a base station of a broadband network

摘要

In order for professional mobile terminals for a critical mission of public security to make use of the radio infrastructure of a broadband network, for instance of the LTE type, the downward and upward frames are configured in a base station each in a first area dedicated to mobile terminals of lower priority and a second area dedicated to mobile terminals of critical mission of high priority. In the second area, sub-channels dedicated to a group of terminals of critical mission are allotted by order of priority to this group, to another group of mobile terminals of critical mission and to mobile terminals of lower priority.

主权项

1. A method in a base station for allotting blocks of radio resources to mobile terminals in downward frames emitted by the base station and in upward frames received from the mobile terminals, the blocks of resources being distributed in time and in frequency in the frames, said method comprising:
a configuration of each downward frame into first and second areas dedicated to data respectively to be emitted toward a plurality of first mobile terminals and a plurality of second mobile terminals and from each downward frame into first and second areas dedicated to the data respectively to be received from the first and second mobile terminals, an allotment of blocks of resources in the first areas of downward and upward frames shared between data to be emitted to and to be received from the first mobile terminals, the positions of a block of resources allotted to data to be emitted toward the first mobile terminal and of a block of resources allotted to data to be received from the first mobile terminal being variable in the first areas, an allotment of at least one block of resources having a predetermined position in the second areas of the downward frames in priority to data to be emitted toward all of the plurality of the second mobile terminals, and an allotment of at least one block of resources having a predetermined position in the second areas) of the upward frames in priority to data to be received from one of the plurality of the second mobile terminals.
