Method of scheduling for enhanced dedicated channel (E-DCH)
View Patent ↗A method of scheduling for an Enhanced Dedicated Channel (E-DCH) in a user equipment (UE) is disclosed. More specifically, a method of receiving an information indicating an allowable transmit power range from a base station and updating a group of Transport Format Combinations (TFCs) allowed by the base station by selecting the TFCs that can be used within the allowable transmit power range. Furthermore, the method comprises transmitting the E-DCH by at least one TFC selected from the group of TFCs.
1. A method of transmitting an Enhanced Dedicated channel (E-DCH) by user equipment (UE), the method comprising:
received, at the UE, scheduling information from a base station, scheduling information including an offset value that represents a relative difference between a presently assigned maximum transmit power level and a current maximum transmit power level;
update, at the UE, a value that represents assigned maximum transmit power level base on the offset value received from the base station;
selecting, at the UE, a transport Format Combination (TFC) base on the update value that represents assigned maximum transmit power level; and
transmitting the E-DCH in according with the selected TFC, wherein the presently assigned maximum transmit power level is determined at the base station at least based on actual transmit power range associated with the UE or the location of the UE relative to the base station.
2. The method of claim 1 , wherein updated value is the maximum transmit power associated with the E-DCH.
3. A method of controlling transmit power for an Enhanced Dedicated channel (E-DCH) by a base station, the method comprising:
transmitting scheduling information from the base station to user equipment (UE), the scheduling information including an offset value that represents a relative difference between a presently assigned maximum transmit power level associated with the UE and a current maximum transmit power level associated with the UE, and
receiving, at the base station an E-DCH which was transmitted by the UE in accordance with a Transport Format Combination (TFC), wherein the TFC is based on an updated, current maximum transmit power level, wherein the updated, current maximum transmit power level was updated based on the offset value, and wherein the presently assigned maximum transmit power level associated with the UE is at least based on actual transmit power range associated with the UE or the location of the UE relative to the base station.
4. The method of claim 3 , wherein transmitting scheduling information comprises:
transmitting a plurality of offset values, wherein each offset value corresponds with a corresponding one of a plurality of UE.
5. The method of claim 4 , wherein the plurality of offset values are determined at the base station based on actual transmit power ranges associated with the plurality of UE.
