    摘要： System(s) and method(s) that facilitate assignment mismatch recovery are provided. A projected level of resources required to satisfy one or more communication constraints (e.g., inter-cell and intra-cell interference) is generated. The projected resources are contrasted with scheduled resources and a determination is made as to whether a mismatch between assigned and projected resources exists. A mismatch is recovered through an adaptive response that feeds back magnitudes for the communication resources which are compatible with the communication constraints.

    摘要： Systems and methodologies are described herein that facilitate techniques for design of relay backhaul to support mobility of relay nodes in a wireless communication system. According to various aspects herein, techniques are provided to enable and support the use of mobile relays and to facilitate handover of mobile relays between respective donor cells. More particularly, techniques are provided herein for relay backhaul control channel assignment associated with hand in or hand out of mobile relays, access/backhaul resource partitioning for mobile relays, and management of quality of service (QoS) requirements associated with a relay handover.

    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.
