Abstract:
1. An integrated circuit structured to control operation of a mobile terminal, the integrated circuit comprising one or more processing devices configured to: receive a semi-persistent scheduling activation transmitted from a base station to the mobile terminal via a physical downlink control channel signaling; when semi-persistent scheduling is not activated, cause the mobile terminal to transmit a scheduling request to the base station in order to request uplink resources for uplink transmission including transmission of a buffer status report; and when semi-persistent scheduling is activated, check a setup information element of a respective logical channel to determine whether to trigger a scheduling request or not, wherein, when a determination is made to trigger the scheduling request, the step of transmitting the scheduling request to the base station is performed by the mobile terminal for the logical channel, when a determination is made not to trigger the scheduling request, the step of transmitting the scheduling request to the base station is not performed by the mobile terminal, the physical downlink control channel signaling is received by the mobile terminal from the base station for activation of a scheduling mode, including a dynamic scheduling mode in which radio resources are dynamically allocated by dynamic grants and a semi-persistent scheduling mode in which radio resources are allocated on a semi-persistent basis by semi-persistent scheduling grants, and the setup information element is considered in the transmission of the buffer status report.
