摘要： A method and a communication system for efficiently managing interference between femtocells and between each femtocell and a macrocell. The disclosed frequency assignment scheme for the femtocells minimizes interference between a femtocell and a macrocell and among different femtocells using a spectrum-sensing technique. The scheme selects a suitable channel from a set of candidate channels and ensures that the femtocell has an acceptable coverage area even when it is close to the macrocell base station. Additionally, the frequency assignment scheme favors a co-channel implementation to take advantage of the hand-off and cell search characteristics. In one embodiment, a joint power control and frequency band assignment technique partitions the coverage area of the macrocell into an inner region, a power control region, and an outer region. Power control may be used within the power-control region while, in the other regions, a fixed transmission power may be used.

摘要： Methods are disclosed to support power saving states of a beacon station in an ad hoc wireless local area network (WLAN). Some of the methods allow exchanging power management information among stations in the wireless network and to allow beacon station handovers. In some methods, always-on stations are given a higher priority to become a beacon station or a beacon station handover destination. The methods achieve good power saving while minimizing beacon handover frequency.

摘要： Methods for increasing power saving in a station that sends or receives frames in an ad hoc wireless network (e.g., IBSS), while allowing the station to enter a power-saving mode quickly upon completion of scheduled tasks. At the same time, a method of the present invention allows two stations in the ad hoc wireless network to infer each other's power management mode without requiring an ATIM/ACK exchange between the STAs within an ATIM window. Consequently, a station may enter a power-saving mode promptly without impairing the station's ability to receive packets. In one embodiment, a "more data" field is used between stations to exchange information. Stations with various computation abilities provide information under different time constraints. The stations may enter power-saving modes that send multicast/broadcast frames or use promiscuous mode within an ATIM window.

摘要： Packet communication method and system in which a packet destined for a terminal is provided service according to a service table indexed by packet classification and the terminal's power mode. The service table may specify for a connection a predetermined quality of service or discarding the packet. For a power mode having an alerting (i.e., paging) mechanism, the service may include alerting the terminal. The service table may also include a network edge point's own service requests and service requests from terminals, provisioning servers, and handoff sources. For a multicast or broadcast packet, as each terminal may be in a different power mode, the associated service in the service table may therefore be different for each terminal. In that case, the packet is provided with service so that any given terminal is provided with at least the quality of service specified in the service table. Thus, a multicast or broadcast packet is discarded when the service specified for all terminals is "discard." Each terminal is alerted, however, if the associated service includes alerting the terminal. During handoff, a part of service table associated with the terminal can be transferred from the handoff source to the handoff destination.

摘要： A femtocell increases efficiency and coverage of a macrocellular network operating in a co-channel manner within the macrocell spectrum by selecting subcarriers for its mobile station using both the subcarrier allocation map received from the macrocell and a spectrum sensing operation. Interference is avoided by selecting only subcarriers not allocated by the macrocell and subcarriers allocated to users not nearby to the femtocell. Interference is eliminated from the received signals using co-channel interference avoidance techniques. Selection of subcarriers for femtocell use may take into consideration inter-carrier interference detected.

摘要： Active scanning method in a wireless network for fast determining available access points (106, 806) using inter-AP (Access Point) communication is described. In the scanning method, a mobile station (102, 802) sends Probe Request for Proxy frame to the current AP (104, 804) serving the mobile station (102, 802). In response to the Probe Request for Proxy frame, the current AP (104, 804) send Proxy Probe Request packet to the appropriate APs (106, 806). In response to the Proxy Probe Request packet, the neighbor APs (106, 806) send Probe Response frame to the mobile station (102, 802) on its operating channel. Since the mobile station (102, 802) moves to the channel being examined after sending the Probe Request for Proxy frame, it receives the Probe Response frame if it is in the coverage area of the neighbor AP (106, 806). The content of Probe Response frame provides the mobile station (102, 802) with the information to be used in handoff decision and network join procedures. Thus, the mobile station (102, 802) neither has to move to the channel to be examined nor send Probe Request frame on that channel. This enables active scan to be initiated even when the neighbor AP (106, 806) is operating in PCF (Point Coordination Function) and the network is in CFP (Contention Free Period), during which unassociated mobile stations (including the scanning mobile station) cannot send packets.
摘要翻译：描述了使用AP间（接入点）通信来快速确定可用接入点（106,806）的无线网络中的主动扫描方法。在扫描方法中，移动台（102,802）向服务于移动台（102,802）的当前AP（104,804）发送针对代理帧的探测请求。响应于探测请求代理帧，当前AP（104,804）将代理探测请求分组发送到适当的AP（106,806）。响应于代理探测请求分组，邻居AP（106,806）在其操作信道上向移动台（102,802）发送探测响应帧。由于移动台（102,802）在发送用于代理帧的探测请求之后移动到正在被检查的信道，因此如果它在邻居AP（106,806）的覆盖区域中，则它接收探测响应帧。探测响应帧的内容向移动台（102,802）提供要在切换决定和网络加入过程中使用的信息。因此，移动台（102,802）既不必移动到要检查的信道，也不必在该信道上发送探测请求帧。这使得即使在邻居AP（106,806）在PCF（点协调功能）中操作并且网络处于CFP（无争用周期）中时也启动主动扫描，在此期间，未关联的移动台（包括扫描移动台）不能发送数据包。
