Method and device for configuring a carrier indication field for a multi-carrier

摘要

Provided are a method and device for configuring a carrier indication field (CIF) for a multi-carrier. A method for allocating a CIF in a carrier aggregation system includes: transmitting carrier aggregation configuration information having at least one secondary component carrier to a terminal through a primary component carrier; allocating a CIF value to the primary component carrier and to the at least one secondary component carrier; and maintaining or removing a CIF value allocated to a deactivated secondary component carrier when the secondary component carrier having the allocated CIF value is deactivated.

1. A method for allocating a Carrier Indication Field (CIF) in a carrier aggregation system, the method comprising:
transmitting carrier aggregation configuration information including at least one secondary component carrier to a User Equipment (UE) through a primary component carrier; allocating CIF values to the primary component carrier and the at least one secondary component carrier, wherein a first CIF value corresponds to a value of the primary component carrier and a second CIF value corresponds to a value of a first secondary component carrier; maintaining the second CIF value regardless of the deactivation of the first secondary component carrier; and allocating a third CIF value when a second secondary component carrier is newly set to the UE, wherein the second CIF value is different from the third CIF value, and wherein the UE performs monitoring Physical Downlink Control Channels (PDCCHs) of the primary component carrier and the second secondary component carrier by estimating that the second CIF value of the deactivated first secondary component carrier is added.
