Abstract:
1. A method of wireless communication, comprising: determining a cyclic prefix duration for orthogonal frequency division multiple access (OFDMA) symbols to be transmitted wirelessly in a multi-media broadcast over a single frequency network (MBSFN) area, wherein the cyclic prefix duration is calculated to accommodate a propagation delay between an evolved Node B (eNB) and one or more user equipment (UE) or other eNBs in the MBSFN that has a duration that exceeds a predefined duration; determining a subcarrier spacing for the MBSFN; determining a transmission time interval (TTI) corresponding to an MBSFN subframe transmitted in the MBSFN; determining, based on the cyclic prefix duration, the subcarrier spacing, and the TTI, a distributed pattern for reference signals in an MBSFN subframe configuration; and providing one or more of the eNB and the UE with the MBSFN subframe configuration for communicating the MBSFN subframe.
