Abstract: A small base node such as a Home Base Node (HNB), or femto cell, may reduce its transmit power in order to prevent co-channel or adjacent channel interference, or to limit its coverage area. Once the power is set, the HNB signal to a served Home User Equipment (HUE) its transmit Common Pilot Channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HNB adjusts other parameters (such as Random Access Channel (RACH) constant value) to compensate for the error in signaled CPICH power, and thus compensate in that process the error in determining path loss. Similarly, if the uplink sensitivity is adjusted, to prevent interference, parameters would also be adjusted and signaled to the HUE to reflect the link imbalance.

Abstract: A multi-mode access point supports different radio access technologies (e.g., Wi-Fi and cellular) for serving multi-mode access terminals. To provide improved service for such an access terminal, the access point may redirect the access terminal from a first type of radio access technology to a second type of radio access technology under certain circumstances. A decision to invoke such a redirection may be based on, for example, at least one of: traffic conditions on the first type of radio access technology, traffic conditions on the second type of radio access technology, and whether a backhaul for the access point is currently a bottleneck for access point communication.
