Patent ID: 8792440

Claim:
A method for a mobile terminal comprising the steps of: receiving by the mobile terminal a semi-persistent scheduling activation from a base station; and transmitting by the mobile terminal a scheduling request to the base station in order to request uplink resources for uplink transmission including transmission of a buffer status report if semi-persistent scheduling is not activated, wherein if semi-persistent scheduling is activated, the mobile terminal checks a setup information element of a respective logical channel to determine whether to trigger a scheduling request or not, if the mobile terminal determines 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, if the mobile terminal determines 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 setup information element of a respective logical channel 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.
