Abstract: Techniques for supporting positioning for a terminal (sometimes referred to herein as a target device) in a wireless network are described. In an aspect, positioning for a target device includes transmitting a Request Assistance Data message to a location server, the Request Assistance Data message indicating at least one positioning method from a plurality of supported positioning methods. The Request Assistance Data message comprises common parameters that are applicable to all positioning methods indicated in the Request Assistance Data message. The common parameters comprise a serving cell identifier. Positioning for the target device further includes receiving assistance data sent in response to the Request Assistance Data message, and performing positioning based on the received assistance data.

Abstract: Techniques for supporting positioning for a terminal (sometimes referred to herein as a target device) in a wireless network are described. In an aspect, positioning for a target device includes receiving a Request Location Information message that indicates at least one positioning method from a plurality of supported positioning methods. The Request Location Information message comprises common parameters that are applicable to all positioning methods indicated in the Request Location Information message. The common parameters comprise a quality-of-service (QoS), an indication of whether periodic location information is requested, an indication of whether triggered location information is requested, or any combination thereof. Positioning is performed in response to the Request Location Information message and can include determining a location estimate for a location of the target device.

Abstract: Confusion resulting from assigning the same node identifier to multiple nodes is resolved through the use of confusion detection techniques and the use of unique identifiers for the nodes. In some aspects an access point and/or an access terminal may perform operations relating to detecting confusion and/or providing a unique identifier to resolve confusion.

Abstract: A method for registration-less paging includes establishing a mobile device identity for a mobile device in a wireless network, determining a time instance for the identified mobile device to listen to pages, and sending a page from the wireless network to the identified mobile device during the determined time instance. In one example, the method is for a network-initiated attach procedure and includes receiving a request to attach a mobile device in a wireless network, generating a paging message based on the request to attach the mobile device, sending a paging indicator to a mobile device based on the paging message during a time instance based on an agreed rule, and accepting an attach procedure from the mobile device based on the paging indicator.

Abstract: Traditional rules that apply to cell selection are overridden to allow cell selection on an acceptable cell, in addition to cell selection on a suitable cell. Once a mobile device acquires service on an acceptable cell, mobile device can inform network of the emergency call in progress or initiation of an emergency call, which allows network to perform necessary actions to support the emergency call during establishment/reestablishment.

Abstract: Techniques for supporting positioning for terminals in a wireless network are described. In an aspect, positioning may be supported by a location server that can reside in different entities. In one design, the location server may obtain positioning information (e.g., measurements) for a target device via a common positioning protocol. The location server may use the common positioning protocol regardless of where it resides and may communicate with other entities via this protocol. The location server may determine location information (e.g., a location estimate) for the target device based on the positioning information. In another aspect, positioning may be supported by transporting multiple positioning messages together. In yet another aspect, positioning may be supported by transporting a positioning message containing multiple parts defined by different organizations.

Abstract: Confusion resulting from assigning the same node identifier to multiple nodes is resolved through the use of confusion detection techniques and the use of unique identifiers for the nodes. In some aspects an access point and/or an access terminal may perform operations relating to detecting confusion and/or providing a unique identifier to resolve confusion.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for startup and recovery of a radio link between a relay node and a donor base station. According to certain aspects, a relay node may perform a random access procedure utilizing a random access channel (RACH) to transition between Uu interface operations and Un interface operations. According to certain aspects, the relay node may perform radio link failure (RLF) recovery utilizing RACH procedures for a Un interface. The procedures described herein, according to certain aspects, may utilize a dedicated relay RACH resource and a Relay Physical Downlink Control Channel (R-PDCCH).

Abstract: The number of handover-related failures that occur in a communication system may be reduced by taking target access point conditions into account when declaring radio link failure and/or by delaying certain handover operations. In some aspects, criteria for radio link failure detection and access terminal-controlled mobility may take into account access point parameters related to neighboring cells that may be available as mobility targets. For example, filtering mechanisms for detecting radio link failure based on radio layer problem reports may also take into account the availability of various neighbor access points and their measured signal strengths. In addition, a handover command may be sent earlier than in conventional systems (e.g., the handover command may be sent even though the target access point is weaker than the source access point) and include an indication that instructs the access terminal to delay handover until a specified condition is met.

Abstract: A communication node determines that radio link failure occurred during connected state mobility of an access terminal and reports the radio link failure to another communication node. For example, a target access point may determine that radio link failure occurred during handover of an access terminal and send a radio link failure report message to the access point that was previously serving the access terminal or to some other node (e.g., a network node). In the first case, the serving access point may adjust mobility parameters based on this radio link failure information and, optionally, other reported radio link failure information. In the second case, the other node may send a radio link failure report message to the serving access point, or the other node may adjust mobility parameters based on this radio link failure information (and, optionally, other reported radio link failure information) and send the adjusted mobility parameters to the serving access point.

Abstract: Techniques for performing frequency hopping in a wireless network are described. In an aspect, frequency hopping may be performed based on both cell identity (ID) and system time information. In one design, a user equipment (UE) may determine a cell ID of a cell and may obtain system time information for the cell. The UE may determine resources to use for transmission with frequency hopping based on the cell ID and the system time information. In one design, the UE may initialize a PN generator in each radio frame with an initial value determined based on the cell ID and a system frame number (SFN) for the radio frame. The UE may determine the resources to use for transmission based on a hopping function, a mirroring function, and a PN sequence from the PN generator. The UE may send a transmission on the resources to the cell.

Abstract: The described aspects include methods and apparatus for performing positioning for a user equipment (UE). The UE can communicate with a plurality of serving cells in a multicarrier configuration, and can indicate a plurality of serving cell identifiers corresponding to the plurality of serving cells in a message to a positioning server. The positioning server can obtain location information corresponding to at least a portion of a plurality of cells, or related eNBs, related to the plurality of serving cell identifiers, and can communicate the location information to the UE. The UE can perform positioning based at least in part on the location information.

Abstract: An access terminal may switch to a different mode of wireless network selection as a result of manual selection of a wireless cell set (e.g., a closed subscriber group) associated with one or more wireless cells. For example, if the user of an access terminal selects a closed subscriber group in a wireless network that is different than the current wireless network, the access terminal may enter a manual mode of wireless network selection, select the wireless network corresponding to the closed subscriber group, and register on a closed subscriber group cell in the selected wireless network. In addition, an access terminal may automatically switch to a different mode of wireless network selection (e.g., the prior mode) upon losing coverage of a wireless cell set. An access terminal may also automatically select a cell of a wireless cell set if the access terminal returns to a cell of the cell set within a defined period of time after losing coverage of the cell set.

For example, a target access point may determine that radio link failure occurred during handover of an access terminal and send a radio link failure report message to the access point that was previously serving the access terminal or to some other node (e.g., a network node). In the first case, the serving access point may adjust mobility parameters based on this radio link failure information and, optionally, other reported radio link failure information. In the second case, the other node may send a radio link failure report message to the serving access point, or the other node may adjust mobility parameters based on this radio link failure information (and, optionally, other reported radio link failure information) and send the adjusted mobility parameters to the serving access point.

Abstract: Facilitating feedback to a third generation partnership project (3GPP) long term evolution (LTE) or subsequent network is described herein. By way of example one or more blocks of downlink transmission resources (e.g., downlink channel) can be correlated to one or more blocks of uplink transmission resources (e.g., uplink channel) during scheduling of a transmission allocation period. For instance, the correlation can identify to terminal devices a particular uplink channel that can be used to transmit, among other things, a negative acknowledgement (NACK) related to a particular downlink channel. Additionally, multiple uplink resources can be employed to facilitate a quantitative and/or qualitative determination of severity of data loss. Furthermore, a limiting factor can reduce a number of terminal devices responding to lost data simultaneously, reducing feedback interference.
