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 inter-frequency handover the Node B shall use a TPC pattern of (nx01)+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 <i>DL TPC pattern </i><i>01 count IE </i> in the cell setup procedure.

Claim
1. Method, comprising the steps of: preparing a radio link addition request for communication from a radio network controller (RNC) to a logical node (Node B) responsible for radio transmission/reception in one or more cells to/from a user equipment (UE), and in case an added radio link is a part of a first radio link set (RLS) established toward said UE, setting an information element (IE) indicative of said first RLS established toward said UE, and sending said IE to the Node B from the RNC along with or separately from the radio link addition request.
2. The method of claim 1, further comprising the steps of: receiving said IE from said RNC at said Node B and thereafter, for cases of inter-frequency handover of said added radio link, sending a transmit power control (TPC) pattern from said Node B to said UE until uplink synchronization of said added radio link is achieved with power-up commands interspersed with a series of alternative power-up and power-down commands, and commencing a closed-loop power control procedure after said synchronization is achieved.
3. The method of claim 2, wherein said TPC pattern comprises n instances of digital symbols zero and one (01) plus one instance of digital symbol one (1) wherein n is determined from a second information element sent from the RNC to the Node B and wherein said pattern is repeated periodically.
4. The method of claim 2, wherein for cases of soft handover of said added radio link, unless said added radio link is part of said first RLS, said TPC pattern is sent with all power-up commands
5. Method, comprising the steps of: receiving a radio link addition request from a radio network controller (RNC) at a logical node (Node B) responsible for radio transmission/reception in one or more cells to/from a user equipment (UE), and in case an added radio link is a part of a first radio link set (RLS) established toward said UE, receiving, at said Node B, an information element (IE) indicative of said first RLS established toward said UE and thereafter, for cases of interfrequency handover of said added radio link, sending a transmit power control (TPC) pattern from said Node B to said UE with power-up commands interspersed with a series of alternating power-up and power-down commands until uplink synchronization of said added radio link is achieved.
6. The method of claim 5, wherein said TPC pattern comprises n instances of digital symbols zero and one (01) plus one instance of digital symbol one (1) wherein n is determined from a second information element sent from the RNC to the Node B and wherein said pattern is repeated periodically.
7. The method of claim 5, wherein for cases of soft handover of said added radio link, unless said added radio link is part of said first RLS, said TPC pattern is sent with all digital one (1) symbols-.
8. Method, for use before achievement of synchronization of an uplink from a user equipment (UE) to a logical node (Node B) responsible for radio transmission/reception in one or more cells to/from said UE in case said uplink is part of a radio link that is in turn part of a first radio link set (RLS) established toward said UE, if said establishment comprises a radio link addition to said first radio link set, comprising the steps of: receiving a transmit power control (TPC) signal pattern with power-up commands interspersed with a series of alternating power-up and power-down commands from said Node B at said UE until uplink synchronization is achieved between the UE and the Node B, and controlling uplink power on said uplink according to said TPC pattern periodically repeated until said uplink synchronization is achieved, after which a closed-loop power control procedure is commenced between said Node B and said UE.
