    Abstract: Methods, systems, and devices for wireless communications are described. A base station may perform a channel access procedure on a shared radio frequency spectrum band using a first beam configuration. The base station may transmit, based at least in part on successful completion of the channel access procedure, a reservation request message (RRQ) to a user equipment (UE) using a second beam configuration, the second beam configuration comprising a beam width that is equal to or narrower than a beam width of the first beam configuration. The base station may receive a reservation response message (RRS) from the UE in response to the RRQ, the RRS comprising a third beam configuration that is based at least in part on the second beam configuration.

    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: 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.

    Abstract: In a wireless communication system, a cell may perform a method for adapting a long-term or short-term almost blank subframe (ABS) configuration, including determining, by the cell, a current neighbor cell deployment state, and adapting a long-term downlink ABS configuration of the cell based on the current neighbor cell deployment state. The current neighbor cell deployment state may include, for example, a number of neighbor cells, signal strengths of the neighbor cells, or a number of users being served in Cell Range Expansion (CRE), which may be determined using a Neighbor Listen module, receiving measurement reports from UEs, or receiving reports from small cell neighbors via a backhaul. Adapting the long-term downlink ABS configuration of the cell may include increasing a proportion of ABS-vacated resources in proportion to an change in neighbor cell deployment density, increasing neighbor cell signal strength, or increasing number of users served in CRE by neighbor cells.

    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.

    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.
