Abstract
A method performed in a system comprising a joint traffic direction scheduler configured to coordinate time-division-duplexing (TDD) transmissions for multiple cells comprises obtaining TDD operation information from each of the cells, determining, based on the obtained TDD operation information, a transmission direction to be used by each of the cells during one or more transmission time intervals (TTIs), and indicating to the cells the determined transmission direction.
Claims20
A method performed by a joint traffic direction scheduler of a base station configured to coordinate time-division-duplexing (TDD) transmissions to be performed by multiple cells of a coordination group, the method comprising:
- obtaining, by the joint traffic direction scheduler, TDD operation information from each cell of the multiple cells in the coordination group;
- determining, by the joint traffic direction scheduler and based on the obtained TDD operation information, a transmission direction to be used by each cell during an upcoming period of time including one or more transmission time intervals (TTIs) of each cell;
- and
- indicating, by the joint traffic direction scheduler, to each cell the determined transmission direction to be used by that cell during the one or more TTIs.
A base station comprising a joint traffic direction scheduler configured to coordinate time-division-duplexing (TDD) transmissions to be performed by multiple cells of a coordination group, comprising:
- processing circuitry, memory, and at least one transceiver collectively configured to:
- obtain, by the processing circuitry of the joint traffic direction schedular, TDD operation information from each cell of the multiple cells of the coordination group;
- determine, by the processing circuitry and based on the obtained TDD operation information, a transmission direction to be used by each cell during one or more transmission time intervals (TTIs);
- and
- indicate, by the processing circuitry, to each cell the determined transmission direction to be used during the one or more TTIs.
