Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with improving PCI selection and/or allocation so as to reduce interference from unloaded cells. In one example, a network entity is equipped to determine whether a cell is loaded or unloaded, and allocate a PCI from a common pool of PCIs to the cell when the cell is unloaded. In another example, a network entity is equipped to determine that a cell is to transition between an unloaded state and a loaded state, and use a first PCI from a common PCI pool associated with the cell in the unloaded state and a second PCI associated with the cell in the loaded state. In another example, a communications device is equipped to attempt to access a first cell associated with a first PCI which indicated that the first cell is unloaded.

Abstract: Wireless communication in a heterogeneous network may be facilitated by establishing connections with femto nodes based on page notifications from macro nodes to user equipment (UE). A UE in idle mode may monitor paging resources provided by a macro node, discover presence of a femto node based on signals received from the femto node, and establish a communicative connection with the femto node based on a page notification received from the macro node over the paging resources.

Abstract: An access point is identified based on pilot signal information that appears on different frequencies. Here, a combination of one or more pilot PN spreading codes or one or more PN offsets on different frequencies are used to uniquely identify an access point. For example, upon receipt of a pilot measurement report, a network entity may uniquely identify an access point that transmitted the pilot signals based on at least one pilot PN spreading code or at least one PN offset and a plurality of frequencies identified by the report. Also, to facilitate acquiring this information, a network entity may request an access terminal to conduct an inter-frequency search for pilot signals. Also, an access terminal may maintain pilot information corresponding to access points in a network and use this information to autonomously conduct inter-frequency searches for pilot signals.

Abstract: A system for optimizing mobility robustness is operable by a network entity that detects handovers or connection failures by served access terminals. The network entity defines classifications based on mobility, route, past serving cell, or location information for the served access terminals and associates each of the handovers or connection failures with a related classification. A system for improving handover performance records a time for which an access terminal is served by the network entity before being served by a neighboring cell. A performance metric is determined based on the recorded time and a handover policy is optimized based on the performance metric.

Abstract: An access point is identified based on a plurality of pilot signatures. Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature. For example, an access point may use one PN offset to generate a pilot signal and transmit a message that identifies at least one other PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot-related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal.

Abstract: Techniques for synchronization on a shared communication medium are disclosed. An access point may select, for example, a common sequence, frequency, and time for a first synchronization signal that is coordinated with one or more other access points. The access point may then transmit the first synchronization signal in accordance with the common sequence, frequency, and time. An access terminal may receive, from an access point, a first synchronization signal having a first sequence and a second synchronization signal having a second sequence. The access terminal may then determine an offset in time between the first synchronization signal and the second synchronization signal, and determine a cell identifier group associated with the access point based on the offset.

Abstract: An access point is identified based on a plurality of pilot signatures (pseudo-random noise, PN, spreading codes or scrambling codes). Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature (e.g. PN offset or PN phase). For example, an access point may use one PN offset to generate and transmit a pilot signal and transmit a different message that identifies (includes) at least another PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot- related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal. In a certain aspect of the invention, a femto management system maintains a pool of PN offsets that may be allocated to femtocells mapping between PN offsets and cell -IDs may be carried out.

Abstract: A method for reducing frequent idle handoffs of a wireless communication device is described. A registration request is received by a base station or a femto access point from the wireless communication device. The number of registration requests received from the wireless communication device are counted while the registration timer is running. It is determined that frequent handoffs are happening when the number of registration requests received is greater than a registration threshold. A transmit power of a femto access point is adjusted if the number of registration requests received indicates that frequent handoffs are happening.
