Abstract  Abstract

The invention claims support with enhanced uplink for operating technology. the user equipment UE can be available for a group signature for the enhanced uplink random access signature is selected to generate an access preamble and when operating in the inactive state for sending the access preamble for random access based on the selected signature. the UE from a shared control channel (e.g. HS-SCCH) receiving and allocating resources (e.g. resources for E-DCH) to UE. In one design the UE may determine a pre-assigned UE identity ID associated with the selected signature based on the pre-assigned UE ID for the shared control channel and de-masking the received symbol the symbol after de-masking for decoding to obtain a codeword and based on the code word to determine the allocated resources. UE can keep the sends the data to the Node B using the allocated resources in the inactive state.

Techniques for supporting operation with enhanced uplink are described. A user equipment (UE) may select a signature from a set of signatures available for random access for enhanced uplink generate an access preamble based on the selected signature and send the access preamble for random access while operating in an inactive state. The UE may receive allocated resources (e.g. for an E-DCH) for the UE from a shared control channel (e.g. an HS-SCCH). In one design the UE may determine a pre-assigned UE identity (ID) associated with the selected signature de-mask received symbols for the shared control channel based on the pre-assigned UE ID decode the demasked symbols to obtain a codeword and determine the allocated resources based on the codeword. The UE may send data to a Node B using the allocated resources while remaining in the inactive state.
