    摘要： Systems and methodologies are described that facilitate identifying and/or selecting femto cells in a wireless communication environment. A mobile device can scan an Auxiliary Pilot Channel to detect auxiliary pilot channel information (e.g., a particular Walsh Code, . . . ) sent from a base station. Moreover, the identified auxiliary pilot channel information can be evaluated to detect a characteristic of the base station. For instance, the identified auxiliary pilot channel information can be compared with stored auxiliary pilot channel information (e.g., Walsh Code(s) included in a whitelist, blacklist, . . . ). Moreover, a Synchronization Channel can be read based upon the detected characteristic. Further, a Common Pilot Channel, for example, can be analyzed to search for pseudo-noise (PN) offset(s) reserved for femto cell base stations, and the scan of the Auxiliary Pilot Channel can be initiated in response to detecting at least one reserved PN offset.

    摘要： Cellular network may introduce a large number of limited access/limited range (“small”) base stations deployed by end-users such as home base nodes (HNBs) or Femtocells that provide access to access terminals (ATs) or user equipment (UE) to a core network. A selective discovery approach enables UE to discover and to use a small base station without wasting power to discover an alien base station or to search when not within range of any open small base station. Discovery can entail location-dependent determination (e.g., macro base station triangulation, global positioning system, local broadcast channel, etc.) of being within range of an open femtocell whose identity was manually learned, accessed via a distributed neighbor list, etc. The UE can advantageously tolerate small changes in location without having to relearn the identity of the femtocell. The type of access afforded is advantageously communicated to end user via a display indicator.

    摘要： A method for providing an assignment acknowledgement is provided. The method comprises: decoding forward link control channel data blocks according to parameters provided by an overhead channel message; receiving forward link packet data at an access terminal (AT) via a data channel; identifying an offset which defines that a certain number of subpackets of the packet data have been transmitted before the assignment acknowledgement is to be transmitted; and transmitting the assignment acknowledgement according to the offset to indicate successful decoding of one of the control channel data blocks only if the packet data has not been acknowledged.

    摘要： Devices and methods are provided for facilitating handing over to a hybrid femto access point that implements multiple radio access technologies (RATs), including a first RAT and a second RAT. In one embodiment, the method involves detecting a pilot from the hybrid femto access point, wherein the pilot is associated with the first RAT. The method involves registering with the hybrid femto access point on a first channel associated with the first RAT based upon the detected pilot. A system selection database is analyzed to identify a second channel associated with the second RAT, and a selection to handover to the identified second channel is effectuated.
