摘要： An apparatus, method, and computer-program product are provided for wireless communication between uplink and downlink nodes via a relay. The relay is configured to simultaneously communicate with the uplink and downlink nodes on a common channel. For simultaneous communication, radio resources may be allocated to the relay to maintain orthogonality on both the uplink and downlink.

摘要： Interference management may involve the transmission of interference management messages by wireless nodes that are experiencing interference and appropriate responses by potential interferers that receive the interference management messages. Upon detection of interfering signals, a wireless node may determine whether the signals are from a synchronous interferer or an asynchronous interferer. Based on this determination, the wireless node may use different types of signals to manage the different types of interference. In some aspects, asynchronous interference management may involve backing-off in frequency and/or in time in response to interference signals. Asynchronous interference management may involve transmitting back-off beacons to clear potential interferers from a given carrier. Here, the transmission of beacons by a wireless node may be metered to facilitate fair sharing of communication resources.

摘要： A method and apparatus for dynamic interference management is disclosed. A frequency channel is partitioned into a plurality of groups. Two or more groups are assigned weights reflecting degrees of disadvantage of a node. Each group is further partitioned into a plurality of tones. A node experiencing interference determines a group, selects a tone within the group, and transmits a wireless signal using the selected tone. A receiving node receives a plurality of tones including the selected tone, identifies active tones from the received tones, and determines a response based on the weights of the active tones.

摘要： Multiple control indications are transmitted within timeslots defined for a slotted communication system. For example, a wireless node may transmit a control indication at a beginning of a timeslot and at an end of a timeslot. A control indication may comprise a resource utilization message that a node generates in an attempt reduce inference at the node that is caused by transmissions by neighboring nodes. A node also may synchronize to a received timeslot of another node based on the position of one or more control indications within the timeslot. Here, each control indication may include information that indicates the position of the control indication within the timeslot.

摘要： All or a portion of a timeslot of a slotted communication system may be dynamically designated for transmitting or for receiving. For example, a timeslot originally designated for receiving information at a wireless node may be temporarily designated for transmitting information from the wireless node. Such a designation may be made to accommodate a temporary asymmetry in traffic flow between wireless nodes or may be made based on other criteria. In some aspects, a resource utilization messaging scheme may be employed to mitigate interference associated with the designation of timeslots for transmitting or receiving.
