  • Patent number: 8855138
    Abstract: Systems and methodologies are described that facilitate providing relay nodes in wireless networks. In particular, cluster nodes, which can be regular eNBs, can provide wireless network access to the relay nodes over a backhaul link, and the relay nodes can offer access to devices or other relay nodes to expand network coverage and/or provide increased throughput. User equipment (UE) relays can function as UEs according to a cluster node such that UE relays receive network addressing and can tunnel communications through the cluster node using the backhaul link. Cell relays can function as a cell of the cluster node, such that transport layer communications terminate at the cluster node. In this regard, cell relays can define transport layers to use in communicating with the cluster nodes over the backhaul and with other devices over a provided access link.

  • Patent number: 8849316
    Abstract: 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.

  • Patent number: 8848656
    Abstract: Systems and methodologies are described that facilitate transmitting access point types and/or restricted association parameters using broadcast signals, such as beacons, pilot signals, and the like. The type or restricted association information can be indicated by one or more intrinsic aspects of the signal, such as specified parameters. In addition, the type or information can be indicated by one or more extrinsic signal aspects, such as frequency, interval, periodicity, and the like. Using this information, a mobile device can determine whether an access point implements restricted association. If so, the mobile device can request an access point or related group identifier before determining whether to establish connection therewith. The identifier can be verified against a list of accessible access points or groups to make the determination.

  • Patent number: 8843069
    Abstract: Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a first station (e.g., a base station or a terminal) may send a first message to at least one interfering station to request reduction of interference on at least one resource. The first station may send the first message in anticipation of receiving data on the at least one resource. An interfering station may receive the first message from the first station and may reduce interference on the at least one resource by reducing its transmit power and/or by steering its power in a direction different from the first station. The first station may thereafter receive data from a second station on the at least one resource. The techniques may be used for data transmission on the forward and reverse links.

  • Patent number: 8825046
    Abstract: Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a serving base station may send a message to a terminal to trigger short-term interference mitigation. In response, the terminal may send a message to request at least one interfering base station to reduce interference on at least one resource. Each interfering base station may determine a transmit power level to be used for the at least one resource and may send a pilot at this transmit power level. The terminal may estimate the channel quality of the at least one resource based on at least one pilot received from the at least one interfering base station. The terminal may send information indicative of the estimated channel quality to the serving base station. The serving base station may send a data transmission on the at least one resource to the terminal.

  • Patent number: 8787828
    Abstract: In-band provisioning enables subscribers to manually provision themselves via an access point at which the subscribers would not otherwise be allowed access. For example, a subscriber may be temporarily accepted by a restricted access point (e.g., an access point that belongs to a closed subscriber group). The subscriber is then given limited access to enable the subscriber to be provisioned at the access point. For example, the subscriber may be provisioned for full access at the access point if the subscriber presents a valid authorization credential to a provisioning entity.

  • Patent number: 8737295
    Abstract: 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.

  • Patent number: 8731551
    Abstract: Problems caused by interaction between paging optimization and synchronizing CSG information are mitigated by setting a network indication indicating, for example, that a subscriber is no longer a member of a CSG, but the network has not yet received confirmation that an access terminal associated with the subscriber has been informed of this. A timer-based scheme may be employed for removing a CSG ID from the subscriber information for a subscriber once it is determined that the subscriber is no longer a member of the CSG. In addition, a temporary member of a CSG may determine whether it is still a member of a CSG upon expiration of a CSG timer. Also, the frequency with which an access terminal registers may be changed based on various criteria. Furthermore, an allowed CSG list may be selectively included in a page message depending on the destination of the page message.

  • Publication number: 20140064068
    Abstract: Interactions between radio access network (RAN)-based and legacy wireless local area network (WLAN) mobility is described in which a multi-mode mobile device receives a management indication from a wide area wireless network (WWAN) to manage connectivity with the WLAN, such as in discovery, association, or specific traffic offload for the WLAN. The mobile device obtains a status of its internal WLAN radio and determines whether to process the management indication based on the status. Data offloading is also described in which the mobile device receives an indication from the WWAN to offload data to the WLAN associated with the mobile device. In response, the mobile device suspends application of a current offload policy, which had been received from the core network, based on the indication and transmits its data according to the indication.

  • Publication number: 20140016488
    Abstract: The described aspects include methods and apparatus for activating a transmitter to communicate in a wireless network. A small cell can determine to activate the transmitter to serve user equipment (UE) in a wireless network. The small cell can then broadcast a portion of a set of broadcast signals in a radio frame and broadcast a remaining portion of the set of broadcast signals along with the portion of the set of broadcast signals in a subsequent radio frame. By refraining from immediately broadcasting all broadcast signals, the small cell can mitigate interference to other small cells. In addition, a UE can determine whether to generate random access channel (RACH) sequences for proximity determination or uplink timing synchronization based on parameters received in a RACH order. Moreover, a small cell with an active transmitter can decode discovery signals from a device to facilitate handover determination.

  • Publication number: 20140016542
    Abstract: Systems and methodologies are described that facilitate supporting mobility for UEs and relay eNBs in split-cell relay configurations. Parameters regarding communicating with one or more UEs can be provided to disparate eNBs from a donor eNB to provide mobility for one or more of the UEs or a serving relay eNB. In addition, a donor eNB can request establishment of one or more radio bearers at a target relay eNB for continuing communications with one or more UEs. Moreover, a donor eNB can provide information regarding one or more core network bearers to a target donor eNB to facilitate establishing the core network bearers at the target donor eNB for communicating with the one or more UEs. Furthermore, uplink buffer contents from a relay eNB can be provided to a target donor eNB so communications from the one or more UEs can be continued by the target donor eNB.

  • Patent number: 8626162
    Abstract: Systems and methodologies are described that facilitate distributing and/or utilizing a Closed Subscriber Group (CSG) Identifier (ID) that identifies a CSG corresponding to a base station and a CSG indication that distinguishes between the base station permitting access to members of the CSG and permitting access to members and non-members of the CSG. For instance, the CSG ID can uniquely identify the CSG corresponding to the base station. A mobile device can receive the CSG ID and the CSG indication from the base station. Further, the received CSG ID can be compared to CSG IDs included in an allowed CSG list to recognize whether the mobile device is a member or a non-member of the CSG. Moreover, a preference for selecting the base station as compared to a disparate base station can be generated as a function of the received CSG ID and CSG indication.

  • Patent number: 8619733
    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.

  • Patent number: 8588773
    Abstract: Systems and methodologies are described herein that facilitate improved cell search and selection in a wireless communication system. For example, a terminal as described herein can utilize one or more Closed Subscriber Group (CSG)-specific offset and/or hysteresis parameters as described herein to increase the amount of time on which the terminal is allowed to camp on a desirable cell. Additionally, specialized reselection timing can be employed as described herein to increase a delay associated with selecting a Home Node B (HNB) or Home Evolved Node B (HeNB) cell, thereby reducing power consumption associated with rapid cell reselection operations in a densely populated network environment. Further, a two-step reselection process can be performed as described herein in the context of selecting a frequency for cell reselection, thereby mitigating the effects of rapid reselection between cells and/or frequencies due to CSG cell prioritization.

  • Publication number: 20130294327
    Abstract: Network entities in a wireless network cooperate to account and charge for data communicated over the wireless network. Accounting and charging enable the network entities to properly allocate charges to a second user equipment that communicates through a first user equipment, which acts as a relay in the wireless network. A network entity receives a request from the first user equipment related to a packet data network connection relating to the second user equipment. The network entity establishes or modifies a connection between a gateway and the first user equipment in response to the request. Charges for the data may be allocated to the second user equipment for data communicated with the identifier of the second user equipment.

  • Patent number: 8571550
    Abstract: Systems and methodologies are described that facilitate managing access control to Closed Subscriber Groups (CSGs) in a wireless communication environment. A user equipment (UE) can store an operator CSG list, which can be read only and controlled by an operator. Further, the operator CSG list can lack synchronization to a CSG subscription for the UE retained in the network. Thus, upon selecting to access a CSG cell associated with a CSG with a corresponding CSG Identifier (ID) included in the operator CSG list of the UE, a reject message that indicates that the UE lacks authorization for the CSG can be received. Moreover, the CSG ID can be stored as a forbidden CSG ID of the UE in a set of forbidden CSG IDs in response to receipt of the reject message when the CSG ID is included in the operator CSG list.
