## Abstract

A method according to an embodiment of the present invention for receiving, via a terminal, broadcast/multicast data of an asynchronous adjacent cell in a wireless communication system may comprise the steps of: receiving broadcast/multicast transmission schedule information of the asynchronous adjacent cell which is not synchronized with a serving cell of the terminal; and receiving broadcast/multicast data transmitted from the asynchronous adjacent cell on the basis of the broadcast/multicast transmission schedule information.

## Claims

### Claim 1

A method for receiving, by a user equipment (UE), broadcast/multicast data of an asynchronous neighbor cell in a wireless communication system, the method comprising:
receiving, from a serving cell of the UE, first system information of the asynchronous neighbor cell non synchronized with the serving cell, wherein the first system information includes schedule information for broadcast/multicast transmission; and
receiving the broadcast/multicast data transmitted from the asynchronous neighbor cell, based on the schedule information,
wherein the first system information is transmitted by the serving cell instead of second system information of the serving cell at a specific transmission timing among transmission timings of the second system information.

### Claim 2 (depends on 1)

The method of claim 1, wherein the broadcast/multicast data is transmitted in a physical downlink shared channel (PDSCH) related to a demodulation reference signal (DMRS) antenna port from the asynchronous neighbor cell.

### Claim 3 (depends on 2)

The method of claim 2, wherein the DMRS antenna port, and a cell-specific reference signal (CRS) or channel state information (CSI)-RS is quasi-co-located (QCL)-assumed.

### Claim 4 (depends on 1)

The method of claim 1, wherein the schedule information includes at least one of broadcast/multicast transmission timing information of the asynchronous neighbor cell, transmission resource information of broadcast/multicast data of the asynchronous neighbor cell, reference signal (RS) configuration information for demodulating broadcast/multicast data, asynchronization related auxiliary information used for adjusting synchronization with the asynchronous neighbor cell, and quasi-co-located (QCL) information.

### Claim 5 (depends on 1)

The method of claim 1, wherein the first system information is transmitted through a resource independent from a resource in which the second system information is transmitted.

### Claim 6

A user equipment (UE) for receiving broadcast/multicast data of an asynchronous neighbor cell in a wireless communication system, the UE comprising:
a radio frequency (RF) unit configured to transmit and receive a radio signal; and
a processor configured to control the RF unit, and
wherein the UE is configured to:
receive, from the serving cell of the UE, first system information of the asynchronous neighbor cell non synchronized with the serving cell, wherein the first system information includes schedule information for broadcast/multicast transmission, and
receive the broadcast/multicast data transmitted from the asynchronous neighbor cell, based on schedule information, and
wherein the first system information is transmitted by the serving cell instead of second system information of the serving cell, at a specific transmission timing among transmission timings of the second system information.
