Abstract

A method of transmitting and receiving control information in a wireless communication system is disclosed. The method of receiving control information related to a specific point-to-multipoint service in a user equipment of a wireless communication system comprises receiving a notification message including indication information and an identifier identifying the point-to-multipoint service from a network, the indication information indicating at least one downlink channel related to the specific point-to-multipoint service among a plurality of downlink channels established for transmission of control information for at least one or more point-to-multipoint service, and receiving at least one downlink channel indicated by the indication information.

Claims

1. A method of receiving a signal associated with a broadcast service, the method comprising:

receiving, by a user device, a signal through a physical channel from a network, the signal carrying a plurality of OFDM (Orthogonal Frequency Division Multiplexing) symbols in a time domain and a plurality of subcarriers in a frequency domain,

wherein the plurality of OFDM (Orthogonal Frequency Division Multiplexing) symbols carry a frame,

wherein a part of continuous OFDM symbols in the frame is used for transmission of a physical signal channel and a remaining part of continuous OFDM symbols in the frame is used for transmission of a data channel in physical layer,

wherein the frame includes Layer 1 (L1) information channel which is located at a beginning part of the frame,

wherein the Layer 1 (L1) information channel carries notification information and the notification information indicates that information related to the associated broadcast service is changed; and

wherein the Layer 1 (L1) information channel includes identification information for uniquely identifying a data channel for carrying the associated broadcast service, and allocation information on position of the associated broadcast service in the frame,

wherein the allocation information indicates address information of the data channel in a time or frequency-domain.

2. The method of claim 1, wherein the frame further includes Layer 2 (L2) information channel and wherein the Layer 1 (L1) information channel and the Layer 2 (L2) information channel are periodically transmitted.
