摘要： Providing for improved wireless communications for user equipment (UE) in a semi-active state is described herein. By way of example, a base station can employ particular wireless channel resources, monitored by a UE in a CELL_FACH state for instance, to trigger channel feedback information from the UE. The trigger can comprise an explicit order instructing the UE to provide data in response, or can include a portion of downlink traffic targeting the UE, where the UE is configured to respond in a suitable manner to receipt of traffic data. The UE can maintain the CELL_FACH state in receiving to and responding to the trigger, and can further receive subsequent traffic data in such state. Accordingly, the subject disclosure provides for improved efficiency and reliability in semi-active state wireless communications.
摘要翻译：在这里描述为半活动状态的用户设备（UE）提供改进的无线通信。作为示例，基站可以采用例如由CELL_FACH状态的UE监视的特定无线信道资源来触发来自UE的信道反馈信息。触发器可以包括指示UE响应地提供数据的显式顺序，或者可以包括针对UE的下行链路业务的一部分，其中UE被配置为以适当的方式响应以接收业务数据。 UE可以在接收到触发和响应触发时保持CELL_FACH状态，并且可以在这种状态下进一步接收后续的业务数据。因此，本公开提供了半活动状态无线通信中的改进的效率和可靠性。

摘要： Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon over an operating frequency of the macrocell base station, and the macrocell base station, and/or one or more network components, can identify the femto node based on one or more parameters reported by the device from receiving the beacon. The beacon can be transmitted at varying powers to ensure active hand-in triggering, mitigate interference and/or can be powered on and off for such purposes. In addition, a macrocell base station can regulate compressed mode periods during which a device can measure the femto node based on receiving information regarding device proximity to the femto node, or a device can generate proximity indication messages base on measuring the beacon signals, etc.

摘要： A parameter for transmission by an access point is determined in a manner that facilitates access terminal mobility. For example, a cell reselection parameter and/or a handover parameter may be determined based on the quality of a signal from one access point (e.g., a macro cell) at another access point (e.g., a femto cell). In addition, a cell reselection parameter and/or a handover parameter may be determined based on the proximity of one access point (e.g., a femto cell) to another access point (e.g., a macro cell). Through the use of these techniques, a parameter may be determined in a manner that mitigates access terminal ping-ponging between access points and that mitigates outages that may otherwise occur as a result of an access terminal remaining on an access point too long.

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： 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： 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 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.
