Abstract: The disclosure relates to reducing Wi-Fi interference from small cells that provide cellular coverage in unlicensed bands. In particular, in response to determining that a small cell is substantially unloaded (e.g., has traffic below a threshold), the small cell may be switched to a reduced interference configuration. For example, the small cell may be switched to a low downlink configuration to reduce interference in a time domain and/or a low bandwidth configuration to reduce interference in a frequency domain. Alternatively (or additionally), the small cell and/or any other small cells that have traffic below the threshold may switch to the same frequency and/or channel number to concentrate all possible interference on the same frequency and/or channel number. Further still, the configuration may be switched in a power domain, where a transmit power associated with the small cell may be adapted based on cellular measurements in combination with Wi-Fi measurements.

Abstract: A small cell (e.g., femtocell) in a wireless communication may determine a set of wireless signal measurements for a plurality of small cells causing pilot cell pollution within a coverage area. The small cell may determine an adjustment of a transmission parameter of the small cells for reducing the pilot cell pollution, and transmit the adjustment to the small cells. The adjustment may include, for example, minimizing an area of overlap between at least two small cells having signal power difference below a threshold, maximizing a signal to interference and noise ratio at a location associated with at least two small cells, minimizing an area associated with at least two pilot signals within a threshold signal level, distributing traffic load to at least two of the small cells based on the set of measurements, or by minimizing the number of small cells covering a path.

An amount of available bandwidth within a radio frequency band can be determined for shared access by a plurality of operators, where each operator operates a radio access network having one of a plurality of radio communication compatibility types, and where each radio communication compatibility type defines a set of one or more compatible radio access technologies. The amount of available bandwidth can be allocated into radio compatibility type-specific bandwidth partitions for each radio communication compatibility type based on a number of the plurality of radio communication compatibility types and a number of the plurality of operators corresponding to each radio communication compatibility type. A primary channel can be assigned within at least one of the radio compatibility type-specific bandwidth partitions to at least one operator of the number of the plurality of operators.

Abstract: The present disclosure describes a method and an apparatus for communicating during a network listen (NL) mode at a base station. For example, a method is provided for communicating during a network listen (NL) mode at a base station. The example method may include generating a first random number during a first time slot of the NL mode and setting a value of a counter at the base station to the random number generated at the base station. A determination is made whether the base station detects at least one new neighbor base station during the first time slot and the value of the counter is decreased when at least one new neighbor base station is detected during the first time slot. The base station transmits a signal during the first time slot when the value of the counter is determined to be zero.

A relationship between the identifier and the femto cell is then communicated. In another embodiment, a user equipment report is received, which includes attributes related to a signal broadcast by a femto cell. An identifier associated with the femto cell is ascertained from an attribute included in the report. The femto cell is then identified based on the identifier. In a further embodiment, a timing parameter is received, and a scrambling parameter is set. A signal including the scrambling parameter is then broadcast according to an offset related to the timing parameter. In yet another embodiment, a femto cell is detected during an active call. An identifier associated with the femto cell is then ascertained and reported.
