摘要： The present invention relates to fast random access methods and arrangements for the enhanced uplink dedicated channel of E-UTRAN (Evolved Universal terrestrial radio access network). A user equipment (UE) being in a low activity state sends a random access request comprising a preamble on a physical random access channel (PRACH) to a NodeB. The NodeB receives the request and sends in response to the received random access request a response comprising information associated with detection of the preamble on an acquisition indicator channel (AICH). The response comprises further in an extension of the AICH an indication of an action to be taken by the UE. In an embodiment of the present invention the action is to access the E-DCH and the response comprises configuration parameters to the E-DCH.

摘要： Methods for improving uplink communications in a Wideband Code Division Multiple Access (WCDMA) communication system, wherein mobile terminals can transmit at various transmission power levels. In a mobile terminal, the method includes the steps of receiving a configuration message having at least one of a power offset parameter and a maximum number of retransmission attempts parameter; when the mobile terminal performs a non-scheduled transmission, it transmits according to the parameters contained in the configuration message. In a network node, the method includes the steps of transmitting to at least one mobile terminal the configuration message having at least one of a power offset parameter and a maximum number of retransmission attempts parameter; and, adjusting a power setting for the transmission of acknowledgement or negative-acknowledgement messages from the wireless network to one or more of mobile terminals.
