Abstract
A first radio link set (RLS) indicator parameter is added to a radio link addition request message on Iub and on Iur. As in the case of radio link setup, the first RLS indicator IE used in the radio link addition request message indicates if the added RL is to be considered part of the first RLS established toward this UE in that frequency. If the first RLS indicator IE is set to “first RLS”, which means interfrequency handover, the Node B shall use a TPC pattern of (n×01)+1 in the downlink of the added RL and all RLs which are part of the same RLS, until UL synchronization is achieved on the Uu. The parameter n is set equal to the value received in the DL TPC pattern 01 count IE in the cell setup procedure. The TPC pattern is continuously repeated, but restarted at the beginning of every frame with Connection Frame Number (CFN) mod 4=0. For all other RLs, the Node B uses a TPC pattern of all ones in the downlink until uplink synchronization is achieved on the Uu.
