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： Techniques for determining time of arrivals (TOAs) of signals in a wireless communication network are described. Each cell may transmit (i) synchronization signals on a set of contiguous subcarriers in the center portion of the system bandwidth and (ii) reference signals on different sets of non-contiguous subcarriers distributed across the system bandwidth. A UE may determine TOA for a cell based on multiple signals transmitted on different sets of subcarriers. The UE may perform correlation for a first signal (e.g., a synchronization signal) from the cell to obtain first correlation results for different time offsets. The UE may perform correlation for a second signal (e.g., a reference signal) from the cell to obtain second correlation results for different time offsets. The UE may combine the first and second correlation results and may determine the TOA for the cell based on the combined correlation results.

摘要： Techniques are described for providing a-priori information about the implication of a network device operator interaction with a network device, e.g., a software configuration or hardware change, to be performed on the network device before the interaction actually takes place. The network device operator is provided with information that may be used to make a decision whether to proceed with the interaction. For each logically distinct feature of a network device, the techniques generate a trigger outcome domain (TOD). Each TOD is defined to include a list of operator interactions that defines relevant events in the network device that may be triggerable by the operator interactions, a list of potential outcomes in the network based on the potential events in the network device, and a user interface to display the list of potential outcomes for the operator interactions prior to performing any of the interactions.

摘要： An adaptive scheme controls the transmission of interference management messages by wireless nodes. For example, the adaptive scheme may be used to determine whether and/or how to transmit resource utilization messages. Such a determination may be based on, for example, comparison of a quality of service threshold with a current quality of service level associated with received data. A quality of service threshold may be adapted based on the effect of previously transmitted resource utilization messages. A quality of service threshold for a given wireless node may be adapted based on the frequency at which the wireless node transmits resource utilization messages. A quality of service threshold for a given wireless node may be adapted based on information received from another wireless node. An adaptation scheme also may depend on the type of traffic received by a given wireless node. A quality of service threshold also may be adapted based on throughput information.
