Some techniques and apparatuses described herein protect components of a user equipment (UE), such as a low noise amplifier (LNA), from internal interference. For example, the LNA may be disconnected from a receive chain during periods of high internal interference, and may be reconnected to the receive chain during periods of low internal interference. Furthermore, some techniques and apparatuses described herein improve performance by adjusting operations of the UE to account for and/or offset increased internal interference due to a receive chain that does not include a surface acoustic wave (SAW) filter to remove unwanted radio frequency signals. For example, one or more operations of a baseband processor may be modified to account for the increased internal interference. Additionally, or alternatively, reporting of channel state information may be modified to account for increased internal interference of the UE. Additional details are described herein.

Filterless multiple input multiple output (MIMO) reception

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.
