In a radio communication system containing A-DPCH (Associated - Dedicated Physical Channel) and HS-DPCCH (High Speed - Dedicated Physical Control Channel), it is possible to perform an appropriate outer loop transmission power control for the HS-DPCCH even during DTX (Discontinuous Transmission) of the A-DPCH. A transmission data monitoring section (12) monitors whether a bit string transmitted via the A-DPCH is present.

Why it's free to use
- Filed August 14, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 14, 2023.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
