Abstract: Disclosed are systems and methods for regulating frequent handovers by mobile devices between adjacent femtocells. In one aspect, the method includes determining if a mobile device is experiencing frequent handovers between femtocells, classifying frequent handovers based on cause (e.g., ping-pong between the two femtocells or high speed mobile device crossing a number of femtocells, etc.), and determining one or more remedial actions for regulation of frequent handovers based on the number of frequent handovers and their classification.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a semi-persistent scheduling (SPS) grant of initial resources for receiving a transmission, receive, in a group control channel, a resource allocation for additional resources for receiving the transmission, determine resources for receiving the transmission based on the resource allocation and the SPS grant, and receive the transmission on the determined resources. A base station may transmit a SPS grant for scheduling a transmission on a set of resources, receive a feedback report from a user equipment (UE) indicating the UE requires additional resources for receiving the transmission, generate, based at least on the UE requiring the additional resources, a resource allocation for scheduling the additional resources for the UE, transmit the resource allocation in a group control channel, and transmit the transmission on the set of resources and the additional resources.

Abstract: 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.

Abstract: 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.

Abstract: The disclosure provides techniques for reducing interference caused by a first device to a second device receiving a satellite-based positioning signal. A device such as a user equipment (UE) or base station (eNB) determines a threshold transmission power for a transmission frequency of the device. The device also determines a signal strength of the satellite-based positioning system signal at the device. The device then controls a transmission property of the device based on the signal strength of the satellite-based positioning system signal when a transmission power of the device at the transmission frequency satisfies the threshold. The device may also determine that reception of the satellite-based positioning system signal by the second device is likely to be affected by a transmission from the device at a transmission power that satisfies the threshold and control the transmission property when reception of the satellite-based positioning system signal is likely to be affected.

Abstract: A timer parameter used for transitioning between radio protocol states is adapted based on a change of a handover parameter. For example, as a direct result of a change in a handover parameter such as time-to-trigger, offset, or hysteresis, an inactivity timer that is used for switching an access terminal from a connected state to an idle state may be adapted. As another example, as a direct result of a change in a handover parameter, a radio link failure (RLF) timer that is used for switching an access terminal to an RLF state may be adapted.

Abstract: 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.
