Abstract
Embodiments of the invention relate to dynamically setting the number N of HS-SCCH channels to be used as signaling channels of the HS-DSCH traffic channel in a cell served by a Node B, which comprises, at predefined periods of time:
- determining the number N of HS-SCCH channels as a function of one or more of the following:percentage of used downlink transmission power, used_DL_TX_power, with respect to the maximum downlink transmission power in the cell, Cell_Max_DL_TX_power;number of users in the scheduler of the HS-DSCH channel for PS data traffic;number of codes being used for the HS-DSCH channel;number of users for voice over HSPA in the scheduler of the HS-DSCH channel; andsending a message from a Radio Network Controller, RNC, that controls the Node B including the number N of HS-SCCH channels to be used in said cell.
