Abstract
The present specification provides a method by which a user equipment (UE) simultaneously accesses a plurality of cells. The simultaneously access method can comprise the steps of: setting connections with a first cell of a frequency division duplex (FDD) scheme and a second cell of a time division duplex (TDD) scheme; and transmitting and receiving a control signal and data to and from the first cell of the FDD scheme and the second cell of the TDD scheme. Here, an uplink subframe and a downlink subframe for the first cell of the FDD scheme can be temporally divided according to the TDD scheme and provided to the UE.
Claims12
A method by which a user equipment (UE) simultaneously accesses a plurality of cells, the method comprising:
- establishing a connection with a frequency division duplex (FDD)-based first cell and a time division duplex (TDD)-based second cell;
- transmitting and receiving a control signal and data with respect to the FDD-based first cell and the TDD-based second cell;
- and
- transmitting a physical random access channel (PRACH) according to a configuration of a cell corresponding to a primary cell of a carrier aggregation (CA) between the FDD-based first cell and the TDD-based second cell,
- wherein an uplink (UL) subframe and downlink (DL) subframe of the FDD-based first cell is provided to the UE in a time division manner on the basis of TDD.
A user equipment (UE) capable of simultaneously accessing a plurality of cells, the UE comprising:
- a transceiver;
- and
- a processor configured to:
- establish a connection with a frequency division duplex (FDD)-based first cell and a time division duplex (TDD)-based second cell and thereafter for transmitting/receiving a control signal and data, and
- transmit a physical random access channel (PRACH) via the transceiver according to a configuration of a cell corresponding to a primary cell of a carrier aggregation (CA) between the FDD-based first cell and the TDD-based second cell,
- wherein an uplink (UL) subframe and downlink (DL) subframe of the FDD-based first cell is provided to the UE in a time division manner on the basis of TDD.
