摘要： Systems and methods of scheduling sub-carriers in an OFDMA system in which a scheduler takes into account channel conditions experienced by the communication devices to optimize channel conditions. The scheduler can partition a set of sub-carriers spanning an operating bandwidth into a plurality of segments. The segments can include a plurality of global segments that each includes a distinct non-contiguous subset of the sub-carriers spanning substantially the entire operating bandwidth. One or more of the global segments can be further partitioned into a plurality of local segments that each has a bandwidth that is less than a channel coherence bandwidth. The scheduler determines channel characteristics experienced by each communication device via reporting or channel estimation, and allocates one or more segments to communication links for each device according to the channel characteristics.

摘要： Systems and methodologies are described that facilitate providing opportunistic relay node communication based on scheduling of other communications in a wireless network. In particular, a relay node can maintain a backhaul link with an access point and an access link with a mobile device to facilitate communicating information therebetween. Time slots during which the backhaul link is active can be determined and avoided during scheduling access link communications with the mobile device. Furthermore, resource assignments from the access point to the mobile device can be monitored and decoded such that time slots associated therewith can also be determined and avoided. Thus, the relay node can communicate with mobile devices in time slots where the backhaul link is inactive and/or the mobile devices are not occupied communicating directly with the access point.

摘要： Methods and apparatuses are provided that include mitigating interference for devices communicating with femto nodes or other low power base stations by assigning protected resources for communicating therewith. The protected resources can be negotiated with a macrocell base station using interference cancellation. The protected resources can be assigned based on an early or late handover event, which can indicate that the device may be susceptible to interference from the macrocell base station.

摘要： A method for determining channel quality estimates of two or more types of subframes, such as clean and unclean subframes, may be applicable to both legacy and newer user equipment. A first base station affects a channel quality measurement by either transmitting dummy signals over designed tones that correspond to a second base station, or by puncturing transmissions during designated tones that correspond to the second base station.

摘要： Techniques for adjusting transmit timing of base stations and user equipments (UEs) in a wireless network are described. In one operating scenario, a femto base station communicates with a femto UE, and a macro base station communicates with a macro UE located within the coverage of the femto base station. In an aspect, the transmit timing of the femto base station may be delayed relative to the transmit timing of the macro base station, e.g., to time align downlink signals from the femto and macro base stations at the femto and macro UEs. In another aspect, the transmit timing of the femto UE may be advanced relative to the transmit timing of femto base station by an amount larger than twice the propagation delay between the femto UE and the femto base station, e.g., to time align uplink signals from the femto and macro UEs at the femto base station.

摘要： Providing for fair resource sharing among wireless nodes in a wireless communication environment is described herein. By way of example, fairness can comprise establishing a set of resource sharing credits for wireless nodes. By expending credits, a node can borrow a resource of another node, to enable or enhance operation of the borrowing node. Credits for the borrowing node are decreased based on consumption of a shared resource, or credits for the lending node are increased based on such consumption, or both. Once an amount of credits expires, a node can be restricted from borrowing further resources until enough resources are lent to build up a suitable amount of credits. Accordingly, fairness can comprise correlating shared resource consumption with shared resource provisioning, to encourage participation in cooperative wireless communications.
摘要翻译：本文描述了在无线通信环境中的无线节点之间提供公平的资源共享。作为示例，公平性可以包括为无线节点建立一组资源共享信用。通过消耗积分，节点可以借用另一个节点的资源，以启用或增强借用节点的操作。基于共享资源的消耗，借用节点的贷方减少，或者基于这样的消费增加贷款节点的贷款，或两者。一旦一定数量的信用额到期，一个节点可以被限制借用进一步的资源，直到足够的资源被借出来建立一个合适数量的信用。因此，公平性可以包括将共享资源消耗与共享资源供应相关联，以鼓励参与协作无线通信。

摘要： Systems and methods that facilitate management of interference and communication resources are provided. A differential approach is devised in which other-sector interference (OSI) and communication resources are managed by adjusting an offset (delta) value associated with the resources in response to receiving an indication of other-sector interference. An OSI indication can be issued based on a short and a long time scale, and effective interference metrics over time-frequency resources. The adjusted delta value is communicated to a serving access point, which reassigns communication resources in order to mitigate other-sector interference.
