Abstract
Operations of a UE and eNB are provided when there is a cell which can perform cell on/off. In this case, the UE may performs receiving signal on downlink channel and processing with the signal on the downlink channel. In addition, the signal on the downlink channel may includes a discovery signal when the cell is off-state, and the discovery signal is a signal used for cell identification and/or measurement.
Claims9
A method for communicating with a small cell, which supports an on-state and an off-state, and a macro cell in a wireless system, the method performed by a user equipment (UE) and comprising:
- receiving, from the small cell, a discovery signal including an identification which indicates whether the small cell is in the on-state or the off-state;
- determining whether the small cell is in the on-state or the off-state based on the identification;
- and
- performing a discontinuous reception (DRX) operation based on the determined state of the small cell,
- wherein when the identification indicates that the small cell is in the on-state, the UE performs measurement using a cell specific reference signal (CRS), and
- wherein when the identification indicates that the small cell is in the off-state, the UE only receives the discovery signal, performs measurement using the discovery signal, and performs the DRX operation by aligning a cycle of the DRX operation with a cycle of the on-state of the small cell and the off-state of the small cell.
A user equipment (UE) communicating with a small cell, which supports an on-state and an off-state, and a macro cell in a wireless system, the UE comprising:
- a radio frequency (RF) transceiver that transmits and receives a signal;
- and
- a processor, operatively coupled to the RF transceiver, that:
- controls the RF transceiver to receive, from the small cell, a discovery signal including an identification which indicates whether the small cell is in the on-state or the off-state,
- determines whether the small cell is in the on-state or the off-state based on the identification, and
- performs a discontinuous reception (DRX) operation based on the determined state of the small cell,
- wherein when the identification indicates that the small cell is in the on-state, the UE performs measurement using a cell specific reference signal (CRS), and
- wherein when the identification indicates that the small cell is in the off-state, the UE only receives the discovery signal, performs measurement using the discovery signal, and performs the DRX operation by aligning a cycle of the DRX operation with a cycle of the on-state of the small cell and the off-state of the small cell.
