| 摘要 |
The embodiments of this invention propose methods of DRX operations in adaptive TDD systems. In an adaptive TDD network, the actual TDD configurations may change from time to time. If eNB and UE do not synchronize well in the understanding of actual TDD configuration, DRX timers, which are counting in PDCCH subframe basis, may not be aligned in eNB and UE sides. Thus, the DRX active/inactive periods may not be synchronized in eNB and UE sides. It can be a worst case where UE is awake but Network does not transmit anything or Network transmits something for the UE but UE is in sleep mode. To prevent the scenarios mentioned above. Solutions on the counting of DRX timers in adaptive TDD systems are proposed in the embodiments of this invention. |
