Abstract:
1. A scheduling method for high speed uplink packet access, comprising following two levels of scheduling: a first level scheduling for assigning a target Rise over Thermal (ROT) to each User Equipment (UE), wherein said first level scheduling comprises a non-serving Relative Grant (RG) DOWN transmitting determining step and a serving UE target RoT determining step, wherein the non-serving RG DOWN transmitting determining step comprises, when a cell is overloaded and the overloading satisfies a condition for transmitting RG DOWN, determining a non-serving UE that needs to be transmitted with RG DOWN and transmitting determined information from the step of determining the non-serving UE to a second level scheduler, wherein the serving UE target RoT determining step comprises calculating priorities of all serving UEs and sorting them in sequence, assigning an uplink load of the cell available for an enhanced dedicated channel among the serving UEs, determining a target RoT resource assigned to each of the serving UEs, and transmitting the determined information from the step of determining the target RoT resource to the second level scheduler; and a second level scheduling for tracking the assigned target RoT through transmitting a relative grant instruction based on current grant and channel quality of said each UE, wherein said second level scheduling comprises a processing step for each of non-serving UEs and a processing step for the each of the serving UEs, wherein said processing step for each of non-serving UEs comprises transmitting RG DOWN when the non-serving UE is determined to need to be transmitted with RG DOWN, wherein said processing step for the each of the serving UEs comprises evaluating the channel quality after a scheduling grant becomes effective according to current information and historical information of the each of the serving UEs, determining particular grant for the each of the serving UEs according to the target RoT assigned to the each of the serving UEs, determining a scheduling grant instruction to be transmitted, and then transmitting the scheduling grant instruction to the each of the serving UEs, wherein the second level scheduling is performed by the second level scheduler.
