Abstract
The present disclosure relates to a method performed in User Equipment, UE, in a radio network, of managing OVSF codes. The method comprises receiving (Si3) information regarding at least one unused OVSF code, said information identifying at least one unused OVF code index and/or at least one spreading factor, and obtaining (P6) the at least one unused OVSF code based on the received information (Si3). The present disclosure further relates to a method performed in a network node, to a User equipment and to a network node.
Claims23
A method performed in a User Equipment (UE) in a radio network, of managing Orthogonal Variable Spreading Factor (OVSF) codes, the method comprising:
- receiving information regarding at least one unused OVSF code, said information identifying at least one of:
- at least one unused OVSF code index;
- and at least one spreading factor;
- and
- obtaining the at least one unused OVSF code based on the received information, thereby enabling using unused OVSF codes in demodulation of signaling information received from the radio network.
A method performed in a network node of managing Orthogonal Variable Spreading Factor (OVSF) codes, the method comprising:
- obtaining unused OVSF codes,
- forming information regarding the unused OVSF codes, the information identifying the unused OVSF codes by unused OVSF code indices and/or Spreading Factors, SFs, and
- transmitting the information regarding the unused OVSF codes to at least one User Equipment (UE), thereby enabling using unused OVSF codes in demodulation of signaling information received from the radio network by the at least one UE.
A User Equipment (UE) for a radio network comprising:
- an antenna unit,
- a receive unit and a transmit unit, connected to the antenna unit,
- a memory unit, and a control unit arranged to control the function of the receive unit and the transmit unit,
- wherein the receive unit is arranged to receive information regarding unused Orthogonal Variable Spreading Factor (OVSF) codes, and
- wherein the control unit is arranged:
- to obtain unused OVSF codes based on the information regarding unused OVSF codes, said unused OVSF codes being identified by at least one of:
- unused OVSF code indices and Spreading Factors (SFs).
A network node for a radio network, comprising a receive unit and a transmit unit controlled by means of a control unit, and a memory unit,
- wherein the control unit has knowledge about unused Orthogonal Variable Spreading Factor (OVSF) codes at the moment or during coming Transmission Time Intervals (TTIs),
- wherein the control unit is arranged to form information regarding unused OVSF codes based on the unused OVSF codes, the information regarding at least one of:
- unused OVSF codes identifying the unused OVSF codes by unused OVSF code indices;
- and Spreading Factors (SFs), and
- wherein the transmit unit is arranged to transmit the information regarding the unused OVSF codes to at least one User Equipment (UE).
