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 method and apparatus for determining available downlink bandwidth are described. The described aspects may include estimating an available link capacity of a cell for a user equipment. The described aspects may include estimating an available fraction of cell resources for the user equipment. The described aspects may include estimating available bandwidth of the cell for the user equipment as a function of the estimated available link capacity and the estimated available fraction of cell resources. Available bandwidth may be estimated for a cell in a Universal Mobile Telecommunications System (UMTS) system when the user equipment is in an idle mode and/or a connected mode. Available bandwidth may be estimated for a cell in a Long Term Evolution (LTE) system when the user equipment is in an idle mode and/or a connected mode.

Abstract: Apparatus and methods are disclosed for power control of uplink transmissions by a user equipment in a way that can reduce interference to neighbor cells. Various aspects of the disclosure decouple the power control for uplink data transmissions from the power control for uplink for a control channel transmissions. For example, one type of power control command may be utilized to control the power the UE utilizes to transmit data channels such as the DPDCH and/or the E-DCH (e.g., the E-DPDCH and the E-DPCCH). Further, another type of power control command may be utilized to control the power the UE utilizes to transmit control channels such as the HS-DPCCH. In this way, the uplink data channels, which can cause substantial interference to neighbor cells, can be power controlled by those neighbor cells to reduce that interference. Moreover, the control channel corresponding to the downlink data transmissions can be controlled by the downlink serving cell, thus ensuring reliable feedback corresponding to those downlink transmissions.
