摘要： In a handover operation an access terminal is handed over from a source access point to a target access point. To facilitate efficient identification of a target access point, a handover operation may be initiated by the target access point. A candidate frequency search also may be invoked to confirm that an access terminal identified by a target access point for a handover is in the vicinity of the target access point. A source access point may verify whether an access terminal is in a vicinity of a target access point to determine whether to perform a handover operation. A source access point may handle potential ambiguity between several target access points by sending handover commands to each of these target access points. An access terminal also may assist in the determination of whether to perform a handover operation.

摘要： A power calibration scheme adjusts power levels of network of femtocells based on macro signals seen at different points in and around a coverage area and based on the mutual positions of the femtocells (e.g., based on femtocell signals seen at these points). The power calibration scheme thus facilitates a good balance between providing a desired level of coverage and mitigation of interference to nearby macrocells and femtocells.

摘要： Methods and apparatuses are provided that include adjusting rise-over-thermal (RoT) or noise rise (NR) threshold based on detecting interference from one or more devices. A device can communicate within close proximity of a femto node such that the device does not respond to power down commands from the femto node due to operating at a minimum transmit power. The device can cause the RoT or NR at the femto node to potentially rise over a threshold, however. Thus, the femto node can increase the RoT or NR threshold to allow the device to communicate with the femto node without impacting other devices communicating with the femto node. Out-of-cell interference from devices communicating with other base stations can be detected as well, and the RoT or NR threshold can be adjusted based thereon.
摘要翻译：提供了包括基于检测来自一个或多个设备的干扰来调整上升热（RoT）或噪声上升（NR）阈值的方法和装置。设备可以在毫微微节点的非常接近的范围内通信，使得设备由于以最小的发射功率运行而不响应来自毫微微节点的掉电命令。然而，该设备可能导致毫微微节点处的RoT或NR潜在地超过阈值。因此，毫微微节点可以增加RoT或NR阈值，以允许设备与毫微微节点通信，而不影响与毫微微节点通信的其他设备。也可以检测来自与其他基站通信的设备的小区外干扰，并且可以基于此来调整RoT或NR阈值。

摘要： An access point is identified based on a plurality of pilot signatures. 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. For example, an access point may use one PN offset to generate a pilot signal and transmit a message that identifies at least one other 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.

摘要： A small base node such as a Home Base Node (HNB), or femto cell, may reduce its transmit power in order to prevent co-channel or adjacent channel interference, or to limit its coverage area. Once the power is set, the HNB signal to a served Home User Equipment (HUE) its transmit Common Pilot Channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HNB adjusts other parameters (such as Random Access Channel (RACH) constant value) to compensate for the error in signaled CPICH power, and thus compensate in that process the error in determining path loss. Similarly, if the uplink sensitivity is adjusted, to prevent interference, parameters would also be adjusted and signaled to the HUE to reflect the link imbalance.

摘要： A base station in a cellular wireless communications system uses one or more control algorithms to control a transmission pattern of a 1xRTT or DO discovery beacon. The transmission pattern enables access terminals using any one of multiple wake-up periods and wake-up offsets to discover all macrocell frequencies in a finite amount of time. In addition, for base stations allocating a single transmit chain to both 1xRTT and DO beacons, the transmission pattern enables a definite maximum discovery time for both 1xRTT and DO beacons for all access terminals entering the base station coverage.
摘要翻译：蜂窝无线通信系统中的基站使用一个或多个控制算法来控制1xRTT或DO发现信标的传输模式。传输模式使接入终端能够使用多个唤醒周期和唤醒偏移中的任一个在有限的时间内发现所有的宏小区频率。此外，对于向1xRTT和DO信标两者分配单个发射链的基站，传输模式使得对于进入基站覆盖范围的所有接入终端的1xRTT和DO信标都能确定最大发现时间。
