    Abstract: PROBLEM TO BE SOLVED: To provide efficient channel allocation in a network comprising an ad-hoc small-coverage base station.SOLUTION: In some aspect, restricted access nodes are assigned to a designated common channel, and access terminals that communicate in active with a macro access node may selectively be assigned to the designated channel. In some aspect, an access terminal associated with the macro access node may perform a handoff to a different carrier wave when the access terminal is in the vicinity of a coverage area of a restricted access node. In some aspect, an access terminal associated with a macro access node may perform a handoff to a different carrier wave on the basis of location information. In some aspect, access to a restricted access node is controlled on the basis of policy and/or on the basis of operation of an access terminal associated with the restricted access node.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for adaptive server selection in a wireless communication. SOLUTION: An access terminal may be configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the access terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced. COPYRIGHT: (C)2011,JPO&INPIT

A relationship between the identifier and the femto cell is then communicated. In another embodiment, a user equipment report is received, which includes attributes related to a signal broadcast by a femto cell. An identifier associated with the femto cell is ascertained from an attribute included in the report. The femto cell is then identified on the basis of the identifier. In a further embodiment, a timing parameter is received, and a scrambling parameter is set. A signal including the scrambling parameter is then broadcasted according to an offset related to the timing parameter.

    Abstract: PROBLEM TO BE SOLVED: To provide transmit power control techniques for a small base node such as a Home Base Node (HBN), or femto cell to prevent co-channel or adjacent channel interference, or to limit its coverage area.SOLUTION: Once the power is set, the HBN signals to served Home User Equipment (HUE) its Common Pilot Channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HBN adjusts other parameters (such as a Random Access Channel (RACH) constant value) to compensate for the error in the signaled CPICH power, and thus compensate the error in the process of 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.
