Abstract:
According to some embodiments, a method for use in a user equipment of performing cell reselection to a cell providing multimedia broadcast multicast service (MBMS) comprises: receiving a system information message comprising an indication of whether one or more carrier frequencies support MBMS carrier type or further enhanced MBMS (FeMBMS) carrier type; selecting, based on a capability of the user equipment and the carrier type of the one or more carrier frequencies, a carrier frequency for cell reselection; and camping on the selected carrier frequency. In particular embodiments, the system information message further comprises, for each of the one or more carrier frequencies, an indication of a percentage (e.g., 100%, 80%, etc.) of available multicast broadcast single frequency network (MBSFN) subframes in each radio frame.
