Claim of US Patent No. 10,602,484

10. A user equipment (UE) for receiving Evolved Multimedia Broadcast Multicast Service (E-MBMS) in a wireless communication system, the UE comprising:a transceiver; and
a processor, operably connected to the transceiver,
wherein the processor is configured to:
obtain information on a plurality of clusters including a first cluster and a second cluster,
control the transceiver to receive first control information, including information on the first cluster, from the serving cell,
control the transceiver to receive a first E-MBMS signal, in a first subframe, from the first cluster, based on the information on the first cluster,
control the transceiver to receive second control information, including information on the second cluster, from the serving cell, and
control the transceiver to receive a second E-MBMS signal, in a second subframe, from the second cluster, based on the information on the second cluster,
wherein the first control information and the second control information are transmitted in each subframe through a physical control channel,
wherein the first subframe is different from the second subframe, the first cluster is different from the second cluster, and the first E-MBMS signal is different from the second E-MBMS signal,
wherein, when the first and second clusters share one or more cells, a first reference signal sequence used for the first cluster is the same as a second reference signal sequence used for the second cluster,
wherein, when the first and second clusters do not share any cells, the first reference signal sequence used for the first cluster are different from the second reference signal sequence used for the second cluster,
wherein, when a number of at least one cell included in the first cluster or the second cluster is 1, the E-MBMS signal is a single cell point to multipoint (SC-PTM) signal, and when the number of the at least one cell included in the first cluster or the second cluster is equal to or more than 2, the E-MBMS signal is a multimedia broadcast-multicast single frequency network signal, and
wherein the SC-PTM signal is received from a single cell using an extended cyclic prefix.
