Method of controlling noise rise in a cell

摘要

After a maximum noise rise for a cell is set, a maximum noise rise for each mobile station is allocated within the cell. The actual noise rise from each mobile station within the cell is measured at a base station and signaled to a network. When the cell uses enhanced dedicated channel (E-DCH), the contribution to noise rise of E-DCH signaling is determined and received signal code power (RSCP) at the base station is measured. The RSCP measurement is decoded to determine contributions from mobile stations within and outside the cell; contributions from mobile stations within the cell are calculated; and the network is notified of the measured noise rise. In addition a compensation value may be applied to compensate for temperature induced noise.

主权项

1. A method of reporting noise rise in a cell using enhanced dedicated channel operation, the method comprising:
setting a maximum noise rise for a cell; allocating the maximum noise rise among each mobile station within the cell; measuring, at a base station, actual noise rise from each mobile station within the cell; measuring received signal code power at the base station; decoding the received signal code power measurement to determine contributions thereof from mobile stations within and outside the cell; calculating noise contributions from mobile stations within the cell; determining a measured noise rise due to only enhanced dedicated channel transmissions; and notifying a network of the actual noise rise at the base station and the measured noise rise due to only enhanced dedicated channel transmissions.
