摘要
A first method for managing diversity tune away (DTA) on a mobile communication device includes: determining a start of the DTA from a first radio access technology (RAT) to a second RAT before the start of the DTA; transmitting a first aperiodic channel quality indicator/rank indicator (CQI/RI) report to a network on the first RAT prior to the start of the DTA; determining an end of the DTA before the end of the DTA; and transmitting a second aperiodic CQI/RI report to the network on the first RAT prior to the end of the DTA. A second method for managing diversity tune away (DTA) on a mobile communication device includes: inhibiting transmission of periodic channel quality indicator/rank indicator (CQI/RI) reports from the mobile communication device to a network on a first radio access technology (RAT) prior to a start of the DTA to a second RAT; in response to receiving a first aperiodic CQI/RI report request from the network at the start of the DTA, transmitting a first CQI/RI report to the network on the first RAT after the start of the DTA; inhibiting transmission of further periodic CQI/RI reports on the first RAT from the mobile communication device to the network prior to an end of the DTA; and in response to receiving a second aperiodic CQI/RI report request from the network at the end of the DTA, transmitting a second CQI/RI report to the network on the first RAT after the end of the DTA. A third method for managing diversity tune away (DTA) on a mobile communication device includes: reporting a first rank indicator (Rl) to a network during the DTA; receiving, at the mobile communication device, modulation and coding scheme (MCS) information from the network; determining block error rate (BLER) based on error checking of received data packets; evaluating the MCS information and the BLER for a specified signal- to-noise ratio (SNR) over a plurality of system frames; and reporting a second Rl during the DTA based on a BLER threshold corresponding to the MCS and SNR.
