Abstract:
1. A method for wireless communications, comprising: configuring one or more subframes of a frame as Multimedia Broadcast/Multicast Services over a Single Frequency Network (MBSFN) subframes and one or more subframes as non-MBSFN subframes; generating a unicast message to be transmitted in at least one of the MBSFN subframes; determining a pattern for one or more reference signals (RSs) to be transmitted in the at least one MBSFN subframe with the unicast message, the pattern determined based on a transmission scheme of a channel, wherein the one or more RSs comprise user equipment (UE) specific RSs (UE-RSs), transmitting the at least one MBSFN subframe containing the unicast message with the RSs according to the determined pattern in the at least one MBSFN subframe, and wherein a data region of the at least one MBSFN subframe does not contain any MBSFN RS or common reference signals (CRS).
