摘要： Methods and apparatus for communicating short messages from a first device, e.g., a femto cell device or peer to peer device, over communications resources which are being used by an OFDM macro network, e.g., cellular network, are described. The signal goes on top of, e.g., is transmitted on the same communications resource(s), on which a macro signal, e.g. a downlink signal from a cellular base station, is transmitted. Since the signals are transmitted on the same resources as the signals from the macro base station, they interfere with the macro signal. However, the signals transmitted by the femto cell devices and/or peer to peer devices are designed so that they cause little interference to the macro base station in terms of overall throughput and/or with the macro base station's ability to communicate control and/or pilot information.

摘要： Providing for management of wireless communications in a heterogeneous wireless access point (AP) environment is described herein. By way of example, system data of an over-the-air message can be configured to include information identifying a distinct type of transmitting base station. In some aspects, the information can include an access type of the base station and/or a sector ID for distinguishing the base station among large numbers of other base stations. According to other aspects, the information can include wireless channel resources designated for a particular type of base station, or blanked by the transmitting base station, to facilitate interference reduction on such resources. By employing aspects of wireless communication management disclosed herein, efficient and reliable communication can be affected in large heterogeneous AP networks.

摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a serving base station may send a message to a terminal to trigger short-term interference mitigation. In response, the terminal may send a message to request at least one interfering base station to reduce interference on at least one resource. Each interfering base station may determine a transmit power level to be used for the at least one resource and may send a pilot at this transmit power level. The terminal may estimate the channel quality of the at least one resource based on at least one pilot received from the at least one interfering base station. The terminal may send information indicative of the estimated channel quality to the serving base station. The serving base station may send a data transmission on the at least one resource to the terminal.

摘要： Various traffic management techniques may be employed in a multi-hop wireless communication system. For example, a decision to transmit data to another node may be based on whether that node is able to effectively transmit its data. A decision to transmit an interference management message may be based on the amount of data a parent node may transmit. A decision to transmit an interference management message may be based on how effectively data is being transmitted. A weight may be assigned for an interference management message based on a traffic scheduling policy.

摘要： Aspects are disclosed for sequencing and correlating a positioning reference signal. A set of reference symbols associated with a reference signal are allocated, and a base sequence is generated. An extended sequence, which includes the set of reference symbols, is then provided according to the base sequence. The extended sequence is then transmitted in a sub-frame designated as an idle period. A sequence of reference symbols is received from a base station during an idle period of the base station. A replicated sequence of reference symbols is generated, and a correlation is ascertained between a subset of the received sequence of reference symbols and a corresponding subset of the replicated sequence of reference symbols. The received sequence of reference symbols is then identified according to the correlation.
