20100120426 | OPTIMIZED SIGNALING OF PRIMARY SCRAMBLING CODES AND FREQUENCY LISTS IN WIRELESS COMMUNICATIONS - Systems and methodologies are described that facilitate communicating PSC split information regarding neighboring cells. The PSC split information can be transmitted in one or more overhead messages selected based on network deployment. Where macro cells and femto cells provide PSC split information, which can be a PSC range for related cells, PSC list, etc., the information can be transmitted in a low priority overhead message since it can be obtained at a source cell. Where only femto cells or closed subscriber group (CSG) cells provide PSC split information, the information can be transmitted in a higher priority more frequently transmitted message. In this regard, the information is available at target cells since not all devices can access CSG cells. Thus, by providing the PSC split information in a more frequently transmitted message, devices can retrieve the PSC split information early on in communications to lower power consumption. | 05-13-2010 |

For example, the handover message may include measurement report messages (MRMs) generated by the access terminal being handed over. As another example, the handover message may include a neighbor cell list that is associated with the access terminal. The measurement report messages and the neighbor cell list associated with the access terminal will identify physical layer identifiers of cells in the vicinity of the source cell and, in some cases, in the vicinity of the access terminal being handed over. Upon receipt of the handover message, the neighbor cell list for the target cell is updated based on the physical layer identifiers identified by the handover message. | 03-28-2013 |
20130143555 | MANAGING ACCESS TERMINAL HANDOVER IN VIEW OF ACCESS POINT PHYSICAL LAYER IDENTIFIER CONFUSION - Confusion associated with a physical layer identifier is detected and action taken to address this confusion. In some aspects, confusion detection involves determining whether signals such as beacons or pilots that are associated with the same physical layer identifier are also associated with different timing (e.g., different observed time difference (OTD) values).

The femto node can mitigate interference to the devices based on the classification. | 06-13-2013 |
20130217385 | PROXIMITY INDICATION USING OUT-OF-BAND LINKS - Management of user equipment (UE) proximity indications to femto access points is provided using out-of-band (OOB) signals. To obtain OOB identification information on the femto access point, the UE determines the OOB identification information when in proximity to cells neighboring the femto access point. This OOB information is stored in a search information database (SID) of the UE and related to in-band information on the femto access point. To later determine proximity to the femto access point, in response to detecting its presence within a fingerprint area around the femto access point, a search for the femto access point is triggered using the OOB radio resources and OOB identification information associated with the femto access point in the SID. When the UE detects the femto access point using the OOB radio resources, the UE transmits a proximity indication to its serving base station over the in-band radio link. | 08-22-2013 |

When a femto access point is first discovered, a first type of scan is performed of each of the OOB channels. The user equipment (UE) determines whether any received responses originate from femto OOB access points and, if so, updates a search database of the UE. During subsequent visits to the area of the femto OOB access points, when the UE detects entry to a fingerprint area of the femto OOB access point, a second type of scan is performed, in which each of the OOB channels with femto OOB access points identified in the search database are scanned. If responses are detected to this second type of scan, a proximity indication is transmitted using in-band signals to a serving macro access point. | 08-29-2013 |

20140135021 | SYSTEMS, METHODS AND APPARATUS CONFIGURED TO MANAGE NEIGHBOR CELL LISTS - According to some wireless network standards the size of a neighbor cell list is restricted to a maximum size. The limited size of a neighbor cell list may not reflect the realities of a wireless network deployment, especially for deployments including numerous femto cells clustered in close proximity. Accordingly, as the concentration of macro cells and/or femto cells in an area increases, there lies a challenge to identify and communicate neighbor lists to user devices that reflect the arrangement of a particular portion of the deployment and the needs of the user devices. Various systems, methods and apparatus described herein are configured to provide a user device or a group of user devices a neighbor cell list that includes neighbor cell identifiers chosen from a candidate list. | 05-15-2014 |
20140148213 | RANGE TUNING FOR OPEN ACCESS SMALL CELLS - Range tuning for open access small cells may be achieved, for example, by determining a likelihood of handoff for a mobile device around a small cell coverage area, and adjusting a range of the small cell coverage area by controlling a transmit power level of the small cell based on the likelihood of handoff. | 05-29-2014 |
20140274049 | METHOD AND APPARATUS FOR UE MEASUREMENT ASSISTED HANDOVER CLASSIFICATION - A method, an apparatus, and a computer program product for wireless communication are provided in connection with making UE handover decisions. In one example, a node is equipped to obtain one or more UE measurement values associated with a UE, determine a mobility state of the UE based at least in part on the obtained one or more UE measurement values, and adjust one or more handover parameters based at least in part on the determined mobility state of the UE. In another example, a UE is equipped to obtain one or more UE measurements, determine a handover state of a UE based on the obtained one or more UE measurements, and perform a handover-related action based on the determined handover state of the UE. | 09-18-2014 |
20140274063 | SYSTEM AND METHOD FOR MITIGATING PING-PONG HANDOVERS AND CELL RESELECTIONS - Disclosed are system and method for mitigating ping-pong handovers and cell reselections. In one aspect, the system and method are configured detect a plurality of cell changes by a mobile device, determine occurrence of at least one cell more than once in the detected plurality of cell changes, and apply one or more scaling factors to one or more parameters related to cell changes based on the determination. | 09-18-2014 |
20140274195 | SYSTEM AND METHOD FOR DYNAMIC POWER REGULATION IN SMALL CELLS - Disclosed are systems and methods for dynamic power regulation in small cells. In one aspect, a system is configured to determining at least one mobility metric indicative of at least one access terminal mobility at the cell. The system then configured to determine whether the value of mobility metric is acceptable. When the value of mobility metric is unacceptable, the system is configured to increase the transmit power of the cell until the value of mobility metric becomes acceptable. If the value of mobility metric does not become acceptable after increasing the transmit power of the cell above a threshold, the system is configured to decrease the transmit power of the cell. | 09-18-2014 |
20150018042 | METHOD AND APPARATUS FOR PROVIDING ENHANCED INTERFERENCE MANAGEMENT AT RESTRICTED ACCESS POINTS - Methods and apparatuses are provided that facilitate providing access point measurements to restricted access points. Restricted access points can lessen restrictions to allow devices to register with the restricted access point for providing measurements thereto. Additionally or alternatively, access point measurements can be provided to a minimization of drive tests (MDT) server for providing to the restricted access points. Thus, restricted access points can obtain the access point measurements for performing enhanced interference management or other functionality based at least in part on the measurements. | 01-15-2015 |
20150045028 | USER EQUIPMENT SPECIFIC MOBILITY OPTIMIZATION AND IMPROVED PERFORMANCE METRICS FOR IMPROVING HANDOVER PERFORMANCE - 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. | 02-12-2015 |
20150085755 | COORDINATED DETERMINATION OF PHYSICAL LAYER IDENTIFIER AND TRANSMIT POWER - The assignment of physical layer identifiers for access points is coordinated with the assignment of transmit powers for the access points. For example, only those access points that transmit at a relatively high power level are allowed to use a physical layer identifier from a subset of physical layer identifiers allocated for mobility measurements. Any other access points will use a physical layer identifier that is not allocated for mobility measurements. By restricting the number of access points that are allowed to use a physical layer identifier allocated for mobility measurements, confusion and collision in the network may be mitigated. | 03-26-2015 |
20150088656 | ACCESS POINT BROADCASTING OF ADVERTISEMENTS - Advertisements are presented to users of cell phones and other types of access terminals. For example, advertisements may be presented to a user when the user's access terminal is served by or camped on an access point such as a small cell. After obtaining an advertisement, an access point broadcasts a message that includes the advertisement. Advantageously, the advertisement may be broadcast via an HNB Name field defined in 3GPP. Consequently, upon receiving a broadcast including an HNB Name field, an access terminal will automatically display the advertisement included in the HNB Name field (e.g., instead of an HNB Name). | 03-26-2015 |
