  • Publication number: 20100035615
    Abstract: Systems and methodologies are described that facilitate utilizing reselection indicators in reselecting access points in wireless communications. In particular, an indicator can be provided relating to a restricted association access point that specifies whether intra-frequency reselection is allowed. If so, a mobile device receiving the indicator can reselect to other access points, to which it has access, operating in a similar frequency. If not, the mobile device can evaluate access points in other frequencies so as not to cause substantial interference to the restricted association access point. In addition, a predicted level of interference caused by communicating with an intra-frequency access point can be computed and evaluated to override the reselection indicator, in some cases. Thus, a restricted association access point can control reselection for some devices to mitigate interference while allowing the devices to override prohibitive restricted access points.

  • Publication number: 20100029274
    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: 20100027471
    Abstract: Systems and methodologies are described herein that facilitate distributed multiple-input multiple-output (MIMO) or cooperative multipoint (CoMP) communication in a wireless communication system. As described herein, multiple cells, such as a serving cell and an auxiliary cell, can cooperate to conduct communication with one or more associated terminals. In one example described herein, an associated core network can exchange data and/or control signaling with a single cell communicating with a given terminal, which can then tunnel respective data and/or control signaling to other cell(s). By doing so, CoMP communication can be made transparent to the core network and can be achieved without requiring changes to the network. As further described herein, a terminal can exchange Physical Downlink Control Channel (PDCCH) assignments and/or other information exclusively with the serving cell in addition to or in place of other information exchanged with a serving cell and/or an auxiliary cell.

  • Publication number: 20100020710
    Abstract: Systems and methodologies are described that facilitate providing physical cell identifier (PCI) assignment. Neighboring access point parameters can be collected and transmitted to a PCI assigning component, which can generate a PCI based on the parameters as well as other local parameters. The neighboring access point parameters can be received by evaluating signals transmitted by the neighboring access points, from a UE communicating with the neighboring access points, over a backhaul link, etc. The parameters can include signal strength, identification, and/or the like. In addition, prioritized lists of PCIs can be provided to an access point, which can utilize the neighborhood parameters to select an optimal PCI from the list.

  • Patent number: 7649829
    Abstract: Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. Information to be transmitted is provided to a systematic portion of a plurality of transmit buffers and encoded by an outer decoder communicatively coupled to the transmit buffer. The resulting redundant bits are provided to a parity portion of each transmit buffer. The content of the transmit buffers, is multiplexed and encoded by an inner decoder to improve protection by adding redundancy. The receiving station recovers the transmitted information by an inverse process. Because a decoding complexity depends on the size of a systematic portion of the transmit buffer, reasoned compromise between a systematic portion size and number of transmit buffers yields decreased decoding complexity.

  • Publication number: 20100009690
    Abstract: Systems, methodologies, and devices are described that manage employment of network (NW)-initiated resource allocation and user equipment (UE)-initiated resource allocation for a UE. To employ NW-initiated resource allocation, a core network can transmit an indicator to the UE indicating that Policy and Charging Control (PCC) is supported by a network associated with the UE. The UE receives the indicator and other information, such as indicator regarding whether the current access network supports NW-initiated resource allocation and whether the current application prefers NW-initiated resource allocation, determines that NW-initiated resource allocation is to be employed, and the core network initiates resource allocation for the UE. If any indicator is not received by the UE, or the UE receives an indicator that indicates PCC is not supported or not preferred, the UE determines that UE-initiated resource allocation is to be employed, and transmits a request for resource allocation to the core network.

  • Publication number: 20100008234
    Abstract: Paging and power consumption are managed in conjunction with providing local breakout in a wireless wide area network. In some aspects, if a packet destined for an access terminal is received at an access point that provides local breakout, the access point may inform the network so that the network will cause the access point to page the access terminal. Alternatively, in some aspects an access point that provides local breakout may maintain idle context of the access terminal, whereby the access point may autonomously page the access terminal (i.e., without involving the core network). In some aspects local breakout traffic is filtered at an access point to reduce the number of pages or packets sent to an access terminal. In some aspects an indication of a packet type is provided with a page message to enable an access terminal to determine whether to receive the packet. In some aspects a local link interface may be selectively disabled or enabled to limit traffic at an access terminal.

  • Publication number: 20100008235
    Abstract: Conflicting use of a node identifier in a wireless network is reported and resolved. In some aspects, a wireless node receives wireless signals and determines, based on those signals, that more than one node uses the same node identifier. The wireless node may then report the conflicting use to a network node. Here, the wireless node may delay for a period of time before reporting the conflicting use. In some aspects, an access point that discovers a conflicting use (e.g., based on a received signal that indicates that another access point is using that same node identifier) may report the conflicting use and/or elect to use a different node identifier. In some aspects, a stateful procedure is used to resolve a conflicting use where, upon identification of a conflicting use, an access point negotiates with another access point to cause one of these access points to use a different node identifier.

  • Publication number: 20100008293
    Abstract: Systems and methodologies are described that facilitate leveraging an X2-AP interface for data exchange between an access terminal and a Home access terminal. Based upon a received request from a Home access terminal, the access terminal can activate an X2-AP interface connection on demand over Stream Control Transmission Protocol (SCTP) based upon a maximum number of connections not being met and/or a timer evaluation that indicates the request is within an allowed time period. The capacity of the access terminal related to the amount of X2-AP connections can be managed based upon at least one of a timer evaluation, or a maximum number of X2-AP connections. The systems and methodologies provide an optimal and efficient technique in order to enable data to be exchanged between an access terminal and a Home access terminal utilizing an X2-AP interface.

  • Publication number: 20090323577
    Abstract: Techniques for supporting broadcast/multiple transmission to multiple terminals with feedback and rate adaptation are described. In an aspect, a combination of HARQ and at least one shared feedback channel may be used to support broadcast/multicast transmission. In one design, a base station may send at least one transmission of a packet to multiple terminals, one transmission at a time. The base station may receive feedback information (e.g., NAK) for the packet from the terminals on the shared feedback channel(s). The base station may determine whether to terminate the packet early and/or may select at least one transmission parameter for another packet based on the feedback information for the packet. In another aspect, a transport format for a broadcast/multicast transmission may be selected based on CQI information from terminals receiving the transmission. The terminals may send CQI information at a slow rate and/or only certain terminals may send CQI information.

  • Publication number: 20090316655
    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 a network may provide a time gap (e.g., an asynchronous time gap) during which an access terminal may temporarily cease monitoring transmissions from a source node so that the access terminal may acquire a unique identifier from a target node. In some aspects an access terminal may commence handover operations at a target node after determining whether the access terminal is allowed to access the target node. In some aspects a source node may prepare several target nodes for potential handover in the event confusion is detected or likely. Here, the source node may send information relating to the preparation of the potential target nodes to the access terminal whereby the access terminal uses the handover preparation information to initiate a handover at that target node.

  • Publication number: 20090316652
    Abstract: Systems and methodologies are described that facilitate indicating global cell identifier (GCI) reporting in wireless communication to mitigate confusion caused by physical cell identifier (PCI) reporting in heterogeneous deployments. In particular, mobile devices can report GCI of access points to disparate access points to facilitate communication therebetween, such as during handover. Mobile devices can indicate GCI reporting during a system access request by selecting an access sequence corresponding to subsequent GCI reporting. Based on the access sequence, an access point can grant additional resources to receive the GCI, and the mobile device can communicate GCI over the resources. Using the GCI, the access point can communicate with a disparate access point related to the GCI.

  • Publication number: 20090305699
    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.

  • Publication number: 20090268668
    Abstract: Local IP access is provided in a wireless network to facilitate access to one or more local services. In some implementations, different IP interfaces are used for accessing different services (e.g., local services and operator network services). A list that maps packet destinations to IP interfaces may be employed to determine which IP interface is to be used for sending a given packet. In some implementations an access point provides a proxy function (e.g., a proxy ARP function) for an access terminal. In some implementations an access point provides an agent function (e.g., a DHCP function) for an access terminal. NAT operations may be performed at an access point to enable the access terminal to access local services. In some aspects, an access point may determine whether to send a packet from an access terminal via a protocol tunnel based on the destination of the packet.

  • Publication number: 20090264123
    Abstract: Techniques for selecting a serving base station for a terminal by taking into consideration the backhaul quality of candidate base stations are described. In one design, a base station may determine backhaul quality information indicative of its current backhaul quality. The base station may send the backhaul quality information, e.g., in an overhead message sent over the air to terminals or in a backhaul message sent to neighbor base stations or a network controller. A server selection entity may receive backhaul quality information for at least one candidate base station for the terminal. The server selection entity may also determine at least one metric for each candidate base station. The server selection entity may then select the serving base station for the terminal based on the backhaul quality information and the at least one metric for the at least one candidate base station.

  • Patent number: 7599655
    Abstract: A method, apparatus and system provide for efficient use of communication resources for providing broadcast services in a communication system. A receiver receives a first broadcast controller identification from a first base station, and a second broadcast controller identification from a second base station. A controller coupled to the receiver determines whether the first and second broadcast controller identifications are associated with use of a common set of broadcast parameters. A transmitter transmits a request for transmission of a new set of broadcast parameters when the first and second broadcast controller identifications are not associated with use of the common set of broadcast parameters. After receiving the new set of broadcast parameters, the receiver uses the new set of broadcast parameters for receiving broadcast services.
