Abstract: A method of adaptively reporting buffer status by a dual subscriber identity module dual standby (DSDS) terminal is provided. The method includes computing a rate at which uplink (UL) grants are allocated by a network over a period of time for a first subscriber unit associated with the DSDS terminal, determining a first time period to initiate buffer status reporting (BSR) using a radio frequency (RF) unit, wherein the first time period corresponds to a time period in which a BSR interval initializes, determining a second time period in which a second subscriber unit associated with the DSDS terminal requires the RF unit, and adaptively reporting the buffer status based on the rate and a difference between the second time period and the first time period.
