  • Patent number: 9185619
    Abstract: Methods and apparatuses are provided for mitigating interference among access points, and/or devices communicating therewith, in unplanned network deployments. Based on determining that one or more served devices potentially interfere with one or more access points, an inter-frequency handover (IFHO) threshold or data rate can be adjusted for the device to cause IFHO or reduce occurrence of interference, and/or a coverage area can be modified so the device can communicate with one or more other access points to mitigate potential interference. Based on determining interference from one or more devices served by other access points, an access point can switch operating modes to a hybrid or open access point to allow the one or more devices to handover to the access point, and/or can boost downlink transmit power to cause the one or more devices to perform IFHO from the other access points to mitigate potential interference.

  • Publication number: 20150319702
    Abstract: A method or apparatus for configuring OLPC parameters for uplink communications in a cellular wireless network includes determining an estimated number of neighbor cells deployed within radio range of a cell, and configuring OLPC parameters for uplink communications, based on the estimated number of neighbor cells. Determining the estimated number of neighbor cells may include measuring respective signal strengths of the neighbor cells using network listen functionality. At least two OLPC intermediate parameters Po and ? may be selected from a data table, based on the estimated number of neighbor cells. A path loss statistic may be determined, based on UE measurement reports including path losses of UEs to itself and other cells. The OLPC parameters may be selected based on the path loss statistic and Po and ?, and/or adapted based on at least one of UE power headroom reports or overload indicators received from the neighbor cells.

  • Patent number: 9179421
    Abstract: Methods and apparatuses are provided for determining a transmission power cap for one or more devices based at least in part on pathloss measurements to one or more access points received from the one or more devices. A common transmission power cap can also be computed for assigning to devices communicating with an access point, and the transmission power cap for a given device can be adjusted when the transmission power is at or a threshold level from the common power cap to conserve signaling in the wireless network. Adjustment of the transmission power cap can additionally or alternatively be based on a received power at an access point related to signals from the device, an interference report from one or more access points, and/or the like.

  • Publication number: 20150282077
    Abstract: Systems and methods are provided for optimizing resource usage by a network entity that detects a first channel condition for a first radio access technology (RAT) and a second channel condition for a second RAT. The network entity determines whether the first channel condition comprises a higher interference level than the second channel condition and also determines power consumption constraints. If the first channel condition comprises a higher interference level than the second channel condition, the network entity reassigns at least one antenna from the first RAT to the second RAT based at least in part on the power consumption constraints. In some embodiments, systems and methods are also provided for determining whether an access point serving an access terminal is a large cell base station or a small cell base station and determining a power management action for the access terminal.

  • Publication number: 20150282154
    Abstract: A system and method for operation mode adaptation is operable by a network entity that determines channel conditions between the network entity and a second network entity. The network entity determines its hardware constraints and power consumption requirements. The network entity balances data throughput with power consumption for the network entity by selecting a hardware allocation, based at least in part on the channel conditions, the hardware constraints, and the power consumption requirements. In some implementations, the network entity balances data throughput with power consumption for the network entity by selecting an operation mode, based at least in part on the channel conditions, the hardware constraints, and the power consumption requirements.

  • Patent number: 9137713
    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.

  • Publication number: 20150257061
    Abstract: Access terminals are provisioned to conduct intra-frequency, inter-frequency, and inter-RAT measurements and report physical layer identifiers of detected cells. The provisioning may involve cycling through all or a portion of a defined superset of physical layer identifier one subset at a time. In addition, the physical layer identifiers may be prioritized to improve the search procedure. Measurement report messages (including physical layer identifiers of the detected cells) are received at an access point as a result of the provisioning. A neighbor cell list for the femtocell is maintained based on the received measurement report messages and, optionally, other information.

  • Patent number: 9055541
    Abstract: Transmit power for an access point is controlled based on information received by the access point. For example, an access point may employ one or more algorithms that use messages received from nearby access terminals 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. 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 terminal may employ an active access terminal protection scheme to mitigate interference the access point may otherwise cause to a nearby access terminal that is in active communication with another access point.

  • Patent number: 9008030
    Abstract: Methods and apparatuses are provided for determining one or more parameters of an access point that can be set or adjusted to mitigate interference to other access points. A rise-over-thermal (RoT) threshold can be set at an access point based on one or more parameters, such as pathloss measurements, location of the access point, etc., such that interference from devices communicating with the access point can be mitigated. In addition, a noise floor, RoT threshold, etc., can be adjusted based on determining a transmit power difference, out-of-cell interference, and/or similar measurements.

In some aspects, transmit power is controlled based on the number of received messages that correspond to a particular event. In some aspects, transmit power is controlled based on the contents of the received messages. For example, the access point may use signal strength information included in the messages to determine a level of transmit power that mitigates interference at a defined subset of reporting access terminals.
