    摘要： A method and apparatus for User Equipment (UE) power class adaptation for coverage extension in Long Term Evolution (LTE) includes setting a maximum transmit power to a predefined level that is below a maximum capability of a high power UE (HPUE); responsive to determining, based on detected operating conditions local to the HPUE, that an increase in transmit range is required, raising the maximum transmit power towards or to the maximum capability of the HPUE; and subsequently transmitting at an operating transmit power at or below the maximum transmit power as a function of the detected operating conditions local to the HPUE. The method and apparatus allow the HPUE to infer how to configure its maximum power to mitigate interference to the same class of cells, without assistance from an Evolved Node B (eNB) and within the existing 3GPP LTE framework.

    摘要： A method and apparatus for uplink scheduling in the presence of narrowband interference on, for instance, a long term evolution (LTE) network. The uplink scheduling is carried out by a scheduler at a base station (e.g., an eNodeB) that receives allocation requests from user equipment (UEs) and assigns resource blocks in the shared channel to the UEs. The scheduler identifies high-interference resource blocks (RBs) in the shared communications channel. The scheduler assigns UEs to portions of the shared channel having high-interference RBs if the error rate expected to result from the assignment falls at or below an error rate threshold. If the expected error rate is greater than the error rate threshold, the scheduler assigns the UE to another portion of the shared channel.

    摘要： Disclosed herein are methods and systems for embedding a supplementary data channel in OFDM-based communication systems. One embodiment takes the form of a process that includes obtaining a primary data signal that includes a given symbol, where the given symbol includes primary payload data prepended with a given cyclic prefix. The process also includes obtaining supplementary payload data. The process also includes identifying an available portion of the given symbol. The process also includes generating a modified primary data signal at least in part by replacing the available portion of the given symbol with a subset of the supplementary payload data. The process also includes outputting the generated modified primary data signal for transmission via an air interface.

    摘要： A communication system minimizes inter-cell interference and handover holes by providing for a user equipment (UE) to monitor downlink signals from a serving, boundary eNodeB and one or more neighbor eNodeBs, determine a signal quality metric (SQM) for each monitored signal to produce an SQM associated with each eNodeB, and determine a maximum uplink transmit power level (PMAX) for each eNodeB. Based on the determined SQMs and PMAXs, the UE determines a eNodeB of the one or more neighbor eNodeBs with a best SQM and, in response to determining that the neighbor eNodeB of the one or more neighbor eNodeBs with a best SQM is a high power eNodeB, determines a difference between the SQM associated with the high power ENodeB and the SQM associated with the boundary eNodeB. The UE then sets a PMAX for the UE based on the difference determination.
