Automated Parameter Adjustment To Compensate Self Adjusting Transmit Power And Sensitivity Level At The Node B

View page
US Patent:
8271014, Sep 18, 2012
Filed:
Aug 6, 2009
Appl. No.:
12/536896
Inventors:
Aziz Gholmieh - Del Mar CA, US
Farhad Meshkati - San Diego CA, US
Mehmet Yavuz - San Diego CA, US
Siddharth Mohan - San Diego CA, US
Christophe Chevallier - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04B 7/00
US Classification:
455522, 455 69, 455 134, 455 631, 4551151
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.

Transmitting Substitute Reselection Parameters

View page
US Patent:
8483690, Jul 9, 2013
Filed:
Sep 22, 2010
Appl. No.:
12/888169
Inventors:
Farhad Meshkati - San Diego CA, US
Vinay Chande - San Diego CA, US
Mehmet Yavuz - San Diego CA, US
Sanjiv Nanda - Ramona CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 36/08
US Classification:
455438, 455450, 370328
Abstract:
A cell reselection parameter is transmitted on one carrier frequency for a defined period of time to cause access terminals operating on that carrier frequency to more aggressively search for access points on at least one other carrier frequency. For example, a femto cell operating on one carrier frequency may transmit a broadcast channel including a cell reselection parameter such as Sintersearch on another carrier frequency that is used by a macro cell. Here, the value of the cell reselection parameter (e. g. , Sintersearch) is chosen so that the access terminals will more aggressively conduct inter-frequency searches. In addition, the cell reselection parameter is transmitted for a period of time that ensures that a nearby access terminal will receive the parameter during its wakeup interval.

Method And Apparatus For Facilitating A Beacon-Assisted Handover To A Home Node-B For Users On An Active Call

View page
US Patent:
8577378, Nov 5, 2013
Filed:
Jan 29, 2010
Appl. No.:
12/697040
Inventors:
Sumeeth Nagaraja - San Diego CA, US
Mehmet Yavuz - San Diego CA, US
Farhad Meshkati - San Diego CA, US
Andrei D. Radulescu - San Diego CA, US
Christophe Chevallier - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 36/00
H04W 4/00
US Classification:
455444, 45443, 45436, 454321, 370331
Abstract:
Methods, apparatuses, and computer program products are disclosed for facilitating a beacon-assisted handover from a macro network to a femto cell during an active call. A femto cell management system assigns a unique identifier to a femto cell, which the femto cell utilizes to broadcast a beacon at a frequency different than the operating frequency of the femto cell. A wireless terminal receives a control message from the macro network directing the wireless terminal to scan particular frequencies. The wireless terminal subsequently provides a report to the macro network identifying attributes ascertained from the scan, which includes attributes associated with the beacon. The macro network then performs a handover from the macro network to the femto cell as a function of the attributes.

Systems, Methods And Apparatus Configured To Manage Neighbor Cell Lists

US Patent:
8639243, Jan 28, 2014
Filed:
Aug 20, 2010
Appl. No.:
12/860613
Inventors:
Andrei Dragos Radulescu - San Diego CA, US
Peter Hans Rauber - San Diego CA, US
Sanjiv Nanda - Ramona CA, US
Damanjit Singh - San Diego CA, US
Jen M. Chen - San Diego CA, US
Farhad Meshkati - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 4/00
US Classification:
455434, 455436, 455 903, 4554352, 455446, 455444, 455525, 455522, 455418, 455407, 4554351, 370254, 370311, 370331, 370328, 370237, 370352, 370338, 370329, 370410
Abstract:
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.

Autonomous Carrier Selection For Femtocells

View page
US Patent:
20090285113, Nov 19, 2009
Filed:
May 11, 2009
Appl. No.:
12/463695
Inventors:
Mehmet Yavuz - San Diego CA, US
Farhad Meshkati - San Diego CA, US
Sanjiv Nanda - Ramona CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04L 12/26
H04W 72/00
US Classification:
370252, 370329
Abstract:
A carrier for a femtocell is selected from a set of carriers available to femtocells. The femto node determines a preference order for the set and measures received signal strength (RSS) for each carrier. The femto node determines a least interference carrier from the set based on the RSS for each carrier, then defines a selected carrier for the femtocell by comparing the RSS of the least interference carrier to the RSS of other carriers in the set. The selected carrier may have a RSS larger than or equal to the RSS of the least interference carrier offset by a predefined margin. The comparisons may be performed in the preference order. The set available to femto nodes may be a subset of all carriers available to a combination of femtocells and macrocells and one or more of the carriers available to femtocells also may be a carrier available to macrocells.

Self Calibration Of Downlink Transmit Power

View page
US Patent:
20090286496, Nov 19, 2009
Filed:
May 11, 2009
Appl. No.:
12/463714
Inventors:
Mehmet Yavuz - San Diego CA, US
Farhad Meshkati - San Diego CA, US
Mostafa S. El-Khamy - Alexandria, EG
Sanjiv Nanda - Ramona CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04B 1/04
H04B 17/00
US Classification:
4551271, 4552262
Abstract:
Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a total received signal strength from transmitting nodes at the receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference and perform a self-calibration process.

US Patent:
20100273432, Oct 28, 2010
Filed:
Apr 22, 2010
Appl. No.:
12/765398
Inventors:
Farhad Meshkati - San Diego CA, US
Vinay Chande - San Diego CA, US
Mehmet Yavuz - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04B 17/00
US Classification:
455 6711
Abstract:
Systems, devices, and methods for adjusting a transmission power at a femto node are described herein. According to the systems, devices, and methods herein, a measurement of a signal transmitted from a transmitting node may be communicated to the femto node, for example from a user equipment or a neighboring femto node, for use in adjusting the power. The transmitting node may comprise the femto node, a macro node, or a neighboring femto node. In addition, statistics regarding such measurements may be communicated to the femto node for use in adjusting the power. The femto node may also adjust the power based on unsuccessful registration attempts or interference communications received at the femto node.
