Abstract
The present invention related to a method for selecting an uplink cell and an user equipment using the method. The method includes receiving a downlink signal from at least cell of multiple cells, wherein the multiple cells are connected each other via a backhaul, selecting an uplink cell among the multiple cells by selecting a uplink grant for the uplink cell from uplink grants for at least one of the multiple cells, and transmitting a signal to the selected uplink cell.
Claims15
A method for selecting an uplink cell by an user equipment (UE), the method comprising:
- receiving a downlink signal from at least cell of multiple cells, wherein the multiple cells are connected each other via a backhaul;
- selecting an uplink cell among the multiple cells by selecting a uplink grant for the uplink cell from uplink grants for at least one of the multiple cells;
- and
- transmitting a signal to the selected uplink cell.
An user equipment (UE) configured with multiple cells which are connected via a backhaul, the UE comprising:
- a radio frequency (RF) unit for transmitting and receiving a radio signal;
- and
- a processor operatively coupled to the RF unit, wherein the processor is configured for selecting an uplink cell among the multiple cells by selecting a uplink grant for the uplink cell from uplink grants for at least one of the multiple cells,
- wherein the RF unit transmits a radio signal to the selected uplink cell.
