摘要： Transmit power for an access point is controlled based on information received by the access point (106). For example, an access point may employ one or more algorithms that use messages received from nearby access terminals (102, 104) to maintain an acceptable tradeoff between providing an adequate coverage area for access point transmissions and mitigating interference that these transmissions cause at nearby access terminals (104). Here, the access point may employ a network listen-based algorithm upon initialization of the access terminal to provide preliminary transmit power control until sufficient information is collected for another transmit power control algorithm (e.g., an access terminal assisted algorithm). Also, the access point may employ an active access terminal protection scheme to mitigate interference the access point may otherwise cause to a nearby access terminal (104) that is in active communication with another access point (108).
摘要翻译：基于由接入点（106）接收的信息来控制接入点的发射功率。例如，接入点可以使用一个或多个算法，其使用从附近的接入终端（102,104）接收的消息来维持在为接入点传输提供足够的覆盖区域和减轻这些传输在附近接入造成的干扰之间的可接受的折中端子（104）。这里，接入点可以在接入终端初始化时采用基于网络侦听的算法，以提供初始的发射功率控制，直到为另一发射功率控制算法（例如，接入终端辅助算法）收集足够的信息。此外，接入点可以采用主动接入终端保护方案来减轻接入点可能导致与另一接入点（108）主动通信的附近接入终端（104）的干扰。

摘要： An access point transmits cell information via a physical layer channel. In some cases, the cell information sent on the physical layer channel comprises a physical layer identifier. For example, a physical layer channel may be modulated based on a cell identifier and/or a closed subscriber group identifier associated with the access point. Through the use of this cell information, an access point may be quickly identified for mobility and/or interference management operations. In addition, this cell information may be used for finger-printing operations.

摘要： An access point (e.g., a femto cell) that is connected in an active call with an access terminal may cooperate with that access terminal or another access terminal to derive timing information from one or more neighboring access points (e.g., macro access points). In addition, an access point may cooperate with an idle access terminal to derive timing information from one or more neighboring access points. For example, an access terminal may determine the difference between pilot transmission timing or frame transmission timing of a femto cell and a macro cell, and report this timing difference to the femto cell. Based on this timing difference, the femto cell may adjust the timing and/or frequency of its transmissions so that these transmissions are synchronized in time and/or frequency as per network operation requirements.

摘要： Transmissions by a first access point (e.g., a femto cell) are restricted upon detecting an access terminal in the vicinity of the first access point in the event the access terminal is communicating with a second access point (e.g., a macro cell). Upon detection of such an access terminal, the access terminal restricts transmission (e.g., beacon transmission) on a downlink carrier frequency on which the access terminal is actively receiving information from the second access point. This restriction of transmission by the access point may involve, for example, temporarily reducing transmit power, reducing the periodicity of transmission, or ceasing transmission.

摘要： An access point is identified based on a plurality of pilot signatures (pseudo-random noise, PN, spreading codes or scrambling codes). Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature (e.g. PN offset or PN phase). For example, an access point may use one PN offset to generate and transmit a pilot signal and transmit a different message that identifies (includes) at least another PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot- related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal. In a certain aspect of the invention, a femto management system maintains a pool of PN offsets that may be allocated to femtocells mapping between PN offsets and cell -IDs may be carried out.
摘要翻译：基于多个导频签名（伪随机噪声，PN，扩展码或扰码）来识别接入点。这里，除了使用特定导频签名来发送编码（例如，扩频/加扰）的导频信号之外，接入点还发送包括至少一个其他导频签名的至少一个指示（例如，PN偏移或PN 相）。例如，接入点可以使用一个PN偏移来生成和发送导频信号，并发送标识（包括）至少另一PN偏移的不同消息。然后，接收导频信号和消息的接入终端可以生成识别所有这些导频签名的导频报告。在接收到包括该导频相关信息的切换消息时，具有分配给该接入点的导频签名的知识的目标网络实体可以准确地将接入点识别为接入终端的切换目标。在本发明的某个方面，毫微微管理系统维护可以分配给毫微微小区的PN偏移池，可以执行PN偏移与小区ID之间的映射。

摘要： A method for reducing frequent idle handoffs of a wireless communication device is described. A registration request is received by a base station or a femto access point from the wireless communication device. The number of registration requests received from the wireless communication device are counted while the registration timer is running. It is determined that frequent handoffs are happening when the number of registration requests received is greater than a registration threshold. A transmit power of a femto access point is adjusted if the number of registration requests received indicates that frequent handoffs are happening.

摘要： In a multi-level power transmission scheme, an access point transmits at one power level, while repeatedly transmitting at a burst power level for short periods of time. For example, a femto cell may transmit a beacon with periodic high power bursts of short duration, while the femto cell transmit power also undergoes high power bursts aligned with the beacon bursts. In a network listen-based power control scheme, an access point listens for one or more parameters sent over-the-air by the network and then defines transmit power based on the received parameter(s). In some aspects, beacon transmit power may be set based on a defined outage radius parameter and the total received signal power on a channel. In some aspects, access point transmit power may be set based on a defined coverage parameter and the received energy associated with signals from access points of a certain type.

摘要： A femtocell base station includes a transmitter that transmits downlink signals to a mobile station, a receiver that receives uplink signals from the mobile station, a standard transmit pulse-shaping filter, and a narrower transmit pulse-shaping filter that limits the bandwidth of the downlink signals to a greater extent than the standard transmit pulse-shaping filter. The femtocell base station also includes a standard receive pulse-shaping filter and a narrower receive pulse-shaping filter. The femtocell base station is configured to switch between the standard transmit pulse-shaping filter and the narrower transmit pulse-shaping filter, and to switch between the standard receive pulse-shaping filter and the narrower receive pulse-shaping filter. A mobile station may switch from a standard transmit pulse-shaping filter to a narrower transmit pulse-shaping filter to limit uplink interference. A mobile station may switch from a narrower transmit pulse-shaping filter to a standard transmit pulse-shaping filter to achieve a higher data rate.
