Publication number: 20090238185Abstract: Relays can be used to facilitate communication of a packet, such as from a base station to a mobile device. The packet can include a header that designates an intended destination for the packet. The header can transfer such that the intended destination designation can be sent with or without being decompressed at a relay. If there is more than one relay involved in communication, then the header can configure such that the header is accessible without performing decompression. However, if there is one relay stop, then the header can compress the designator in such a way that decompression should occur.Type: ApplicationFiled: January 27, 2009Publication date: September 24, 2009Applicant: QUALCOMM IncorporatedInventors: Gavin B.

Publication number: 20090213825Abstract: Methods and apparatus for controlling transmission of a base station, such as a Femto cell, based on the determined quality of a backhaul connection to a network are disclosed. In particular, a quality of a backhaul connection of a base station to a node in a communication network is determined. Based on this quality determination, transmission from the base station is either limited or stopped when the determined quality fails to meet a predefined condition. The degradation in quality of the backhaul connection, for example, affects the ability of the base station to offer sufficient service to access terminals. By limiting or stopping wireless transmission of the base station when the backhaul quality is degraded, access terminals either currently accessing the base station or attempting to connect to the base station can then more efficaciously hand off to another base station or access point.Type: ApplicationFiled: January 13, 2009Publication date: August 27, 2009Applicant: QUALCOMM IncorporatedInventors: Rajarshi Gupta, Fatih Ulupinar, Gavin B.

Publication number: 20090201818Abstract: Depending on channel conditions, a variable abort timer can be set in relation to wireless communication of data packets. Additionally, available buffer size can be evaluated and used to set a length of the variable abort timer. When a packet sequence is sent, packets can become lost in communication. When a lost packet is recognized, the timer can be initiated and a request for re-transmission of the lost packet can is sent. If the lost packet does not arrive during running of the variable abort timer, then the packet sequence can be processed without the missing packet.Type: ApplicationFiled: February 4, 2009Publication date: August 13, 2009Applicant: QUALCOMM IncorporatedInventors: Ravindra M. Patwardhan, Anurag Vardhan, Parag A. Agashe

Publication number: 20090197570Abstract: Signaling-only access may be established with an access node under certain circumstances such as, for example, upon determining that a node is not authorized for data access at the access node. A node that is not authorized for data access at an access node may still be paged by the access node through the use of signaling-only access. In this way, transmissions by the access node may not interfere with the reception of pages at the node. A first node may be selected for providing paging while a second node is selected for access under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.Type: ApplicationFiled: August 26, 2008Publication date: August 6, 2009Applicant: QUALCOMM IncorporatedInventors: Gavin B.

Publication number: 20090196277Abstract: Systems and methodologies are described that facilitate synchronizing timing among wireless nodes in a wireless communication network. A tracking wireless node can synchronize to a global positioning system (GPS) signal if available. Alternatively, the tracking wireless node can receive quality metrics related to one or more target nodes. The quality metrics can relate to parameters that can be utilized to evaluate the target node for timing synchronization. Based on the quality metrics, the tracking wireless node can select a target wireless node for timing synchronization. The tracking wireless node can subsequently synchronize timing with the target wireless node. In addition, the tracking wireless node can continually evaluate surrounding wireless nodes to detect whether other wireless nodes have higher quality metrics than the current target wireless nodes and can accordingly resynchronize with nodes having higher metrics.Type: ApplicationFiled: January 15, 2009Publication date: August 6, 2009Applicant: QUALCOMM IncorporatedInventors: Gavin B.

Publication number: 20090181672Abstract: Paging load and/or registration load in a network is reduced by using different types of identifiers to specifying which nodes page an access terminal in the network. In some aspects, the network maintains a list that specifies that certain individual nodes (e.g., cells or sectors) are to page a given access terminal and/or that one or more zones (e.g., tracking areas) are to page the access terminal. In some aspects, an access terminal in a network may be configured to provide a forward-looking paging list to the network. The list provided by an access terminal may specify different types of node identifiers (e.g., individual node identifiers, subscriber groups, etc.). The network may then use the list to determine which nodes are to page a given access terminal such that when the access terminal moves to a different node, that node may already be configured to page the access terminal.Type: ApplicationFiled: January 12, 2009Publication date: July 16, 2009Applicant: QUALCOMM IncorporatedInventors: Gavin B.

Publication number: 20090137249Abstract: Systems and methodologies are described that facilitate applying offsets and/or selectable hysteresis values to favor access points in cell reselection. In measuring and ranking surrounding access points in reselection, offsets can be applied to favorable access points to facilitate cell reselection thereto. The offset can positively affect measurements, and thus ranking as well, in some cases. Negative offsets can also be applied to lower measurements (and thus ranking) of some access points. Moreover, hysteresis values can be applied in measuring current cells to prevent frequent reselection. The hysteresis values can be selected based on a type of the current cell or related access point to expand the coverage area where desired. Thus, where the current access point is favorable, a larger hysteresis can be added to measurements related to the current access point.Type: ApplicationFiled: November 12, 2008Publication date: May 28, 2009Applicant: QUALCOMM IncorporatedInventors: Gavin B.

Publication number: 20090137228Abstract: Systems and methodologies are described that facilitate utilizing restriction codes in rejecting connection requests with restricted association access points to indicate a reason for the rejection. Mobile devices can maintain a list of accessible access points and/or groups of access points, which can be consulted during cell reselection to ensure unsuitable restricted association access points are not utilized in cell reselection. Based on receiving a rejection code from a restricted association access point, a mobile device can remove the access point, or a related group, from its maintained list so that subsequent reselection attempts avoid the access point and/or access points in the related group.Type: ApplicationFiled: November 12, 2008Publication date: May 28, 2009Applicant: QUALCOMM IncorporatedInventors: Gavin B. Horn, Fatih Ulupinar, Parag A. Agashe, Rajat Prakash

Publication number: 20090129327Abstract: Systems and methodologies are described that facilitate identifying sectors using sector parameters signatures. The signatures can be generated as a known function of a previous sector parameters signature (or message parameters), system time, and an identifier. In this regard, mobile devices can determine an expected identifier from comparing the sector parameters signature to a sector parameters signature computed based at least in part on the system time known to the mobile device. In addition, the mobile device can utilize a known or an inferred previous parameters signature to determine the expected identifier. Multiple signatures can be evaluated to determine expected identifiers to increase the likelihood of correct identification since the signatures are generated using the known variables along with the identifier.Type: ApplicationFiled: November 12, 2008Publication date: May 21, 2009Applicant: QUALCOMM INCORPORATEDInventors: Gavin B.

Publication number: 20090129291Abstract: An access point is configured based on acquired information. An access point may be configured based on the configuration(s) of at least one other access point. An identifier to be transmitted by an access point may be selected based on the identifier(s) transmitted by at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to a configuration server and the configuration server may respond with a list of neighboring access points for that access point. A configuration server may provide configuration information to an access point based on the location of the access point. A configuration server also may direct an access point to a different configuration server.Type: ApplicationFiled: November 17, 2008Publication date: May 21, 2009Applicant: QUALCOMM IncorporatedInventors: Rajarshi Gupta, Aamod D.
