Abstract: The present disclosure provides systems and methods for adjusting the playback speed of accessories based on the buffer level of the received content. The accessories may receive content from a host device at a certain speed. The incoming speed of the content may be different than the playback speed of the content. Therefore, a buffer level of the received content may be determined using a linear least square (“LLS”) fit of the buffer level, the average of the buffer level, or a phased locked loop (“PLL”) approach. Based on a difference between the buffer level and the playback speed, a speed adjustment may be determined. Instructions may be transmitted from a primary accessory to a secondary accessory to adjust the playback speed by a certain amount at a certain time. This may ensure that the accessories remain in sync. The accessories may then adjust their respective playback speeds.

Abstract: Systems, methods, and apparatuses for using band-limited subframes in wireless communication networks are provided. During the band-limited subframes, the macro cell base station may mute its transmission or transmit at a low power over some frequency sub-band, while transmitting at a normal or higher power over other frequency sub-band. Correspondingly, the small cell base station may communicate with UEs within its coverage at the frequency sub-band that the macro cell base station transmits at a low power. The band-limited subframe enables the small cell base station to communicate with the UE with reduced interference, and in the meantime, increases the throughput of macro cell base station as it does not require the macro cell base station to completely mute its transmission during the band-limited subframe.
