METHOD OF DETERMINING TRANSIT POWER FOR DATA TRANSMISSION BETWEEN A NETWORK AND A USER EQUIPMENT AND RELATED WIRELESS COMMUNICATION SYSTEM

摘要

In a wireless communication system, a network initiates a radio bearer reconfiguration procedure by sending an RADIO BEARER RECONFIGURATION message to a user equipment. Then, the network initiates an active set update procedure by sending an ACTIVE SET UPDATE message to the user equipment. When detecting an inconsistency in the E-DPDCH power interpolation information elements indicated in the RADIO BEARER RECONFIGURATION message and the ACTIVE SET UPDATE message, the user equipment computes a first gain factor using an extrapolation formula. When unable to transmit data based on the first gain factor, the user equipment computes a second gain factor using an interpolation formula. If the data cannot be transmitted based on the second gain factor, the user equipment notifies the network of an unsuccessful radio link.

1. A method of determining transit power for data transmission between a network and a user equipment, comprising:
the network sending a first message to the UE, wherein the first message is associated with a radio bearer reconfiguration procedure and includes a first information element associated with an interpolation formula; the network sending a second message to the UE, wherein the second message is associated with updating an active set of the user equipment; the user equipment computing a first gain factor using an extrapolation formula if the second message does not include a second information element associated with the interpolation formula; the UE computing a second gain factor using the interpolation formula if data cannot be transmitted based on the first gain factor; and the UE transmitting the data based on the second gain factor.
