摘要： A method of managing contention in a wireless network is described. The wireless network may include an access router and a plurality of access terminals connectable to the base station. The method may include designating a data slot as a downlink slot or an uplink slot, and sending a signal from the access router to the access terminals to indicate the designation of the data slot. The access router may determine whether the data slot should be designated as a downlink slot or an uplink slot by assessing information such QoS (quality of service) requirements contained in a REQ message received from one or more of the access terminals, and information regarding buffer level received from one or more of the access terminals.

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 of scheduling among a plurality of nodes may include performing a first sequence of steps followed by a second sequence of steps, each sequence including a Tx step followed by a Rx step. During the Tx step, a node may send a REQ signal containing a request to transmit. During the Rx step, another node may receive the request signal, and respond by sending a confirmation signal indicating an acceptation or a declination of the REQ signal. The REQ signal includes a unicast portion and a broadcast portion. In an uplink mode of the slot, the responding nodes may use the unicast portion of the REQ signal to send supplemental information, in addition to the indication of the acceptation or the declination of the REQ signal.

摘要： A scheduled transmission may be divided up into several segments so that a transmitting node may receive and transmit control messages between segments. In some implementations a monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may otherwise have been transmitted during the scheduled transmission period. In some implementations a wireless media access control supports asynchronous communication and overlapping transmissions. Here, a wireless node may determine whether to request or schedule a transmission based on control messages it receives from neighboring nodes. In some implementations data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

摘要： Ambiguity (e.g., confusion) associated with access point identifiers may be resolved by querying candidate target access points and/or by using historical records indicative of one or more access points that the access point has previously accessed. For example, messages may be sent to access points that are assigned the same identifier to cause the access points to monitor for a signal from an access terminal that received the identifier from a target access point. The target access point may then be identified based on any responses that indicate that a signal was received from the access terminal. In some aspects the access points subject to being queried may be selected using a tiered priority. In addition, it may be determined based on prior handoffs of a given access terminal that when that access terminal reports a given identifier, the access terminal usually ends up being handed-off to a particular access point. Accordingly, a mapping may be maintained for that access terminal that maps the identifier to that access point so that the mapping may be used to resolve any future confusion associated with the use of that identifier by that access terminal.
摘要翻译：与接入点标识符相关联的模糊性（例如，混淆）可以通过查询候选目标接入点和/或通过使用指示接入点先前访问的一个或多个接入点的历史记录来解决。例如，消息可以被发送到被分配了相同标识符的接入点，以使得接入点监视来自接收来自目标接入点的标识符的接入终端的信号。然后可以基于指示从接入终端接收到信号的任何响应来识别目标接入点。在某些方面，可以使用分层优先级来选择被查询的接入点。此外，可以基于给定接入终端的先前切换来确定当接入终端报告给定标识符时，接入终端通常最终被切换到特定接入点。因此，可以为将该标识符映射到该接入点的该接入终端进行映射，使得可以使用该映射来解决与该接入终端的该标识符的使用相关联的任何将来的混淆。

摘要： Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a minimum coupling loss from a transmitting node to a receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference. Transmit power may be defined based on channel quality. Transmit power may be defined based on a signal-to-noise ratio at an access terminal. The transmit power of neighboring access nodes also may be controlled by inter-access node signaling.

摘要： Techniques for using wireless devices to implement sensor networks are described. For cognitive radio, a wireless device obtains measurements for a first system (e.g., a broadcast system) with which the wireless device is not in communication. The wireless device sends the measurements and associated location information and/or timestamps via a second system (e.g., a cellular system). A server receives measurements from a number of wireless devices and determines the coverage of the first system based on the measurements. For other applications, a wireless device obtains sensor information from at least one sensor at the wireless device and sends the sensor information and associated location information and/or timestamps via a wireless system. A server receives the sensor information and associated information from a number of wireless devices, aggregates the sensor information, and constructs a map. The wireless device may develop a user profile based on the sensor information and associated information.

摘要： Techniques to improve the standby time of a station in a wireless network are described. An access point may advertise or convey a maximum listen interval and/or an association timeout supported by that access point. A station may operate in a power-save mode and may wake up every listen interval to receive a beacon and any potential traffic for the station. The station may select a suitable listen interval based on the maximum listen interval. The station may be dormant for a longer duration than the listen interval and may become active at least once in every association timeout in order to keep the association with the access point alive. The access point may also send broadcast and multicast traffic that might be of interest to stations in the power-save mode less frequently and using a special indication message.
