Abstract:
1. A method comprising: receiving, by a terminal, a frame that includes a plurality of subframes, the plurality of subframes including both a normal subframe and a multimedia broadcast multicast service single frequency network (MBSFN) subframe, wherein the normal subframe is a subframe where a cell-specific reference signal (CRS) is transmitted in the entire subframe, wherein the MBSFN subframe is a subframe where the CRS is transmitted in only a part of the entire subframe, wherein the normal subframe is configurable for including two different cyclic prefix (CPs) lengths, a normal length and an extended length as compared to the normal length, wherein a plurality of positioning reference signals (PRSs) are included in both the normal subframe and the MBSFN subframe, wherein the normal subframe is configured to include one of the two different CP lengths, wherein the one of the two different CP lengths is the normal length, wherein a length of a CP of the MBSFN subframe is the same as the length of the CP of the normal subframe.
