Abstract:
1. A method for reporting a buffer status report, comprising: triggering a buffer status report (BSR) and obtaining radio resource information of uplink component carriers in a radio network by a terminal; constructing one or more BSR data units based on information of a buffer data volume to be transmitted; and selecting one or more uplink component carriers from the uplink component carriers with available radio resources, and sending, on radio resources of the selected uplink component carrier(s), the BSR data unit(s) to a network side; wherein the selecting one or more uplink component carriers comprises: when the terminal has available radio resources only on one uplink component carrier, only selecting, by the terminal, the one uplink component carrier; and when the terminal has available radio resources on multiple uplink component carriers, selecting, by the terminal, an uplink component carrier with channel quality-related information having a higher priority than channel quality-related threshold information, according to the channel quality-related information of the radio resource on the uplink component carrier issued by an evolved base station (eNB) on the network side and/or the channel quality-related threshold information configured by the eNB.
