Title: A METHOD AND DEVICES OF PERFORMING A RANDOM ACCESS PROCEDURE BETWEEN A USER EQUIPMENT, U E, AND A RADIO ACCESS NETWORK OF A TELECOMMUNICATION NETWORK
Abstract:
Method of performing a random access procedure between a User Equipment, UE, and a radio access network, wherein two access nodes comprise different sets of signature sequences, wherein said signature sequences are used, by said access nodes, to differentiate requests coming from different UEs, said method comprising the steps of receiving a random access request from said UE, wherein said random access request comprises a signature sequence, determining that said random access request is intended for said first radio access node based on said signature sequence comprised by said request, receiving, from a second access node, said random access request, thereby indicating that said second radio access node has also received said random access request from said UE, and sending a response based on said received random access request from said U E and based on said random access request received from said second radio access node.
