Abstract: 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.

Abstract: An method for wireless communication increases efficiency of its power amplifier (PA) by reducing an insertion loss of a filter (e.g., a transmit (Tx) filter). The method includes detecting, at a user equipment, a dominant spatial direction of interference. The method further includes determining whether to bypass a transmit filter based on an energy level associated with the dominant spatial direction of the interference.
