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.

Abstract: Systems and methods are disclosed that facilitate wireless communication using resource utilization messages (RUMs), in accordance with various aspects. A RUM may be generated for a first node, such as an access point or an access terminal, to indicate that a first predetermined threshold has been met or exceeded. The RUM may be weighted to indicate a degree to which a second predetermined threshold has been exceeded. The first and/or second predetermined thresholds may be associated with various parameters associated with the node, such as latency, throughput, data rate, spectral efficiency, carrier-to-interference ratio, interference-over-thermal level, etc. The RUM may then be transmitted to one or more other nodes to indicate a level of disadvantage experienced by the first node.

Abstract: Techniques for performing carrier switching in a multi-carrier access network are described. A terminal may be assigned to a carrier among multiple carriers having different transmit power levels, e.g., by the access network during system access or handoff. The terminal may receive a switch threshold from the access network. The terminal may periodically measure the received signal strength of the assigned carrier and may compare the received signal strength against the switch threshold. The terminal may refrain from switching to a stronger carrier if the received signal strength exceeds the switch threshold and may switch to the stronger carrier if the received signal strength is below the switch threshold. This carrier switching scheme may prevent the terminal from switching to the strongest carrier when the assigned carrier can provide satisfactory performance. The access network may also switch the terminal to another carrier by sending a carrier switch message.

Abstract translation: 描述用于在多载波接入网络中执行载波切换的技术。 例如在系统接入或切换期间由接入网络将终端分配给具有不同发射功率电平的多个载波之中的载波。 终端可以从接入网接收切换阈值。 终端可以周期性地测量所分配的载波的接收信号强度，并且可以将接收到的信号强度与开关阈值进行比较。 如果接收到的信号强度超过开关阈值，则终端可以避免切换到更强的载波，并且如果接收到的信号强度低于开关阈值，则可以切换到更强的载波。 当分配的载波可以提供令人满意的性能时，该载波切换方案可以防止终端切换到最强的载波。 接入网络还可以通过发送载波​​切换消息来将终端切换到另一载波。

Abstract: A method of wireless communication determines a UE interference condition during handover. A target cell receives information that indicates an interference condition of a user equipment (UE). Prior to completing handover, the target cell determines an expected UE interference condition that will arise after completing the handover of the UE at a target base station. The information can be determined based on a message from the UE. The UE message may indicate which cell is the strongest, indicate the interference condition at both the source and target cells, or only provide a measurement of the strongest cell. Based on the UE measurements, the target eNodeB may schedule the UE on resources based on the expected interference condition at the UE that may arise after the handover.

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.

Abstract: Methods and apparatuses are provided that include handing over relays in wireless networks. Handover request messages for a relay and related user equipment (UE) can be grouped to lessen signaling requirements for handover. Moreover, identifiers can be communicated in the messages to optimize bearer establishment at a target base station to which the relay and related devices are handed over. Also, handover exception cases can occur, which can be handled by the relay and source and target base stations, such as bearer rejection at the target base station, handover failure for one or more devices or the relay, and/or the like. Further, handover of a relay can occur between base stations that house one or more network gateways for the relay, or where the gateways are centralized and accessible by the source and target base stations, where each scenario can include different exception handling.

Abstract: Methods and apparatuses are provided that include scheduling best effort (BE) traffic for devices communicating with a relay. A donor evolved Node B (eNB) schedules BE traffic for various devices based on a historical throughput. The donor eNB can determine a number of devices served by the relay for discounting the historical throughput, and accordingly assigning resources based on the number of devices instead of the single relay. In this regard, the donor eNB can maintain proportional fairness of the BE scheduling. Alternatively, the relay can request a guaranteed bit rate (GBR) bearer to handle the BE traffic, where the requested data rate of the GBR bearer allows for communicating the BE traffic for the number of devices. Resource allocation for BE traffic can also be bound by a maximum throughput at the relay and/or one or more access link data rates.
