摘要： Methods and apparatuses are provided that facilitate providing access point measurements to restricted access points. Restricted access points can lessen restrictions to allow devices to register with the restricted access point for providing measurements thereto. Additionally or alternatively, access point measurements can be provided to a minimization of drive tests (MDT) server for providing to the restricted access points. Thus, restricted access points can obtain the access point measurements for performing enhanced interference management or other functionality based at least in part on the measurements.

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： Downlink codes may be chosen autonomously for femtocells in a wireless communication environment. Downlink transmissions are received from Home NodeBs that are neighbors of the femtocell and macrocell base stations near the femtocell. The downlink transmissions are evaluated to recognize a first set of detected downlink codes that each have a pilot energy above a predetermined detection threshold. An optimal downlink code is selected for use in connection with serving user equipment of the femtocell. The optimal downlink code is based upon the first set of detected downlink codes and selected as a downlink code from a set of downlink codes reserved for the femtocell. The optimal downlink code may be an available downlink code with a smallest amount of detected energy or a randomly selected downlink code from the available downlink codes.

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.

摘要： Aspects describe communications environments in which femtocell capability is provided to devices within the communications network. A non-femto enabled device and/or a femto enabled device can communicate with a femto enabled device in the same geographical area for femto-enabled peer-to-peer communication. Two non-femto enabled devices can be provided femto functionality through utilization of a femto enabled device, which operates as a hub between the two devices. Other aspects relate to enhanced position determination, adaptive coverage enhancement, local mobile networks, open access femtocells without a backhaul, and local broadcast of media though utilization of femto enabled devices.

摘要： A carrier for a femtocell is selected from a set of carriers available to femtocells. The femto node determines a preference order for the set and measures received signal strength (RSS) for each carrier. The femto node determines a least interference carrier from the set based on the RSS for each carrier, then defines a selected carrier for the femtocell by comparing the RSS of the least interference carrier to the RSS of other carriers in the set. The selected carrier may have a RSS larger than or equal to the RSS of the least interference carrier offset by a predefined margin. The comparisons may be performed in the preference order. The set available to femto nodes may be a subset of all carriers available to a combination of femtocells and macrocells and one or more of the carriers available to femtocells also may be a carrier available to macrocells.
摘要翻译：毫微微小区的载波从可用于毫微微小区的一组载波中选择。毫微微节点确定该组的偏好顺序并测量每个载波的接收信号强度（RSS）。毫微微节点基于针对每个载波的RSS确定来自该集合的最小干扰载波，然后通过将该最小干扰载波的RSS与该组中的其他载波的RSS进行比较来为毫微微小区定义所选择的载波。所选择的载波可以具有大于或等于最小干扰载波偏移量的RSS大于预定边距的RSS。比较可以以优先顺序执行。可用于毫微微节点的集合可以是可用于毫微微小区和宏小区的组合的所有载波的子集，并且对于毫微微小区可用的一个或多个载波也可以是可用于宏小区的载波。

摘要： Interference that occurs during wireless communication may be managed through the use of fractional reuse and other techniques. In some aspects fractional reuse may relate to HARQ interlaces, portions of a timeslot, frequency spectrum, and spreading codes. Interference may be managed through the use of a transmit power profile and/or an attenuation profile. Interference also may be managed through the use of power management-related techniques.

摘要： In some aspect restricted access nodes are assigned to a designated common channel while access terminals that are in active communication with a macro access node may selectively be assigned to the designated channel. In some aspect an access terminal associated with macro access node may perform a handoff to a different carrier when the access terminal is in the vicinity of a coverage area of a restricted access node. In some aspect an access terminal associated with a macro access node may perform a handoff to a different carrier based on location information. In some aspect access to a restricted access node is controlled based on policy and/or based on operation of an access terminal associated with the restricted access node.
