Abstract
The present invention provides a method for changing TDD uplink and downlink configuration, including: UE measures interference from the adjacent cells′ UE and reports an interference condition to an eNB; the eNB changes current TDD uplink and downlink configuration according to the interference condition reported by the UE and the current uplink and downlink service requirements. By the present invention, the dynamically changed uplink and downlink service load requirements may be adapted when there is no serious interference between adjacent cells.
Claims9
A method for changing TDD uplink and downlink configuration, comprising:
- a) receiving, by User Equipment (UE), an interference measurement control message of adjacent cells from an evolved NodeB (eNB), wherein the interference measurement control message of adjacent cells indicates a sub-frame on which interference measurement is to be performed;
- b) measuring, by the UE, interference of the adjacent cells' UE on the sub-frame;
- c) transmitting, by the UE, an interference measurement report to the eNB;
- d) receiving, by the UE, a signaling of changing TDD uplink and downlink configuration from the eNB;
- and
- e) receiving and transmitting, by the UE, data according to new TDD uplink and downlink configuration indicated by the signaling.
