Step 101: when UE carries out dispatch request for the first time, or is separated by when carrying out dispatch request once more after the long period, UE sends scheduling request information to Node B on E-RUCCH channel or E-PUCH channel.

Wherein, comprise SNPL information in the said scheduling request information.Said SNPL information is measured by UE, specifically how to measure to belong to known technology, repeats no more here.

Wherein, how UE specifically generates said scheduling request information and how on corresponding channel, to send said scheduling request information belongs to known technology, repeats no more here.

Step 102:Node B is according to the SNPL information in the scheduling request information, estimates the positional information of UE, according to estimating that the positional information that obtains confirms the Initial Trans of E-AGCH channel; And, be the UE scheduling resource according to the resource operating position, generate scheduling grant message.

Wherein, specifically how to estimate that according to SNPL information the positional information of UE belongs to known technology, repeats no more here.

Wherein, in practical application, above-mentioned through SNPL information finally confirm Initial Trans method can for:

Set up the relation mapping table between SNPL information and the power offset values Δ P in Node B side, as shown in table 1:
