A Bluetooth master radio frequency unit addresses a slave radio frequency unit, to enable the slave to synchronize to the master, by sending poll packets and optionally null packets over an active link, the master being arranged so that receipt of a response from the slave unit to a poll packet is sufficient to maintain the active link. The slave unit does not have to respond to all of the poll packets. This approach can allow the slave to preserve more (transmit) power by going into a deep sleep mode in which a low power oscillator may be used while still allowing the master unit to detect whether the slave has resynchronized or not (and thus to update a Link Supervision Timer, for example).

Outer loop link adaptation for device resumption. A user equipment (UE) and base station (BS) may be in communication in a first network (e.g., an LTE network). Communication between the UE and the BS may be interrupted, e.g., due to a long fading environment, the UE tuning away to a second network (e.g., a CDMA network). Accordingly, the measured error rate may increase dramatically. After resumption from the interruption, a negative offset may be applied to a reported SINR value from the UE due to the previous increase in error rate. Upon improvement in the error rate, a larger, positive offset adjustment may be added to the negative offset, allowing the estimated SINR to return to reported SINR more quickly. Additionally, the error rate estimation may be adjusted to converge to a more recently measured more quickly by decreasing a feedback filter coefficient.
