First Claim
Patent Images
1. A method for a contention based uplink transmission, comprising:
- generating a contention based cell-radio network temporary identity (CB C-RNTI) list comprising at least one CB C-RNTI for a contention based uplink transmission of a user equipment;
receiving downlink control information corresponding to each of the at least one CB C-RNTI through a physical downlink control channel (PDCCH) corresponding to the contention based uplink;
selecting a target CB C-RNTI from the at least one CB C-RNTI based on the downlink control information and a transmission criterion of the contention based uplink of the user equipment; and
performing the contention based uplink transmission using the target CB C-RNTI.

Abstract
A contention based uplink transmission method may perform an uplink transmission using a radio resource corresponding to a contention based identity, for example, a contention based cell-radio network temporary identity (CB C-RNTI) suitable for the uplink transmission of a user equipment, based on radio channel quality and a size of uplink data desired to be transmitted.
