PACKET SCHEDULING IN COMMUNICATIONS

摘要

A method is disclosed for scheduling packet data in a communications system. The method comprises configuring (301), in a network apparatus (101), semi-persistent transmission re- sources to a user equipment (102) via higher layer signal- ling, wherein the configuring step (301) includes pre- allocating a data transmission resource and assigning a scheduling request resource to the user equipment (102). A confirmation message (303) is transmitted to the user equipment (102) from the network apparatus (101), wherein the confirmation message (303) informs the user equipment (102) that the user equipment (102) is able to start transmitting data on a physical uplink shared channel PUSCH (304) to the net- work apparatus (101) by using the pre-allocated data trans- mission resource and a pre-configured transmission format, wherein the pre-allocated data transmission resource is linked to the corresponding confirmation message (303), the corresponding confirmation message (303) being linked to the corresponding semi-persistently assigned scheduling request resource.
