Abstract
A method and apparatus for allocating C-RNTI and a communication system. The method includes: generating, by a base station, an expanded C-RNTI for a user equipment, a length of the expanded C-RNTI being greater than 16 bits; and transmitting the expanded C-RNTI to the user equipment. Thereby, a structure of the C-RNTI may be enhanced, and a problem of allocation collision of C-RNTIs in case of a large number of carrier aggregation may be effectively eliminated.
Claims17
An apparatus for allocating a cell radio network temporary identifier (C-RNTI), configured in a base station of a multicarrier aggregation system, the apparatus comprising:
- an expanding unit configured to generate an expanded C-RNTI for a user equipment, a length of the expanded C-RNTI being greater than 16 bits;
- and
- a transmitting unit configured to transmit the expanded C-RNTI to the user equipment.
An apparatus for allocating a cell radio network temporary identifier (C-RNTI), configured in a user equipment of a multicarrier aggregation system, the apparatus comprising:
- a receiving unit configured to receive an expanded C-RNTI transmitted by a base station, a length of the expanded C-RNTI being greater than 16 bits;
- and
- an identifier determining unit configured to determine the expanded C-RNTI as a current C-RNTI.
A communication system, comprising:
- a base station configured to generate and transmit an expanded cell radio network temporary identifier (C-RNTI), a length of the expanded C-RNTI being greater than 16 bits;
- and
- a user equipment configured to receive the expanded C-RNTI transmitted by the base station.
