Method and apparatus for transmitting/receiving control information in broadcast communication system

摘要

Methods and apparatuses for transmitting/receiving control information in a system in which multiple frequencies are used to carry multiple services by means of transmission frames, which are constituted of time resources and/or time-frequency resources. Control information regarding frame configuration information is not transmitted over a separate control channel but over a data channel. The service traffic for each non-primary service traffic may include control information for a primary service. Thus, even when a receiver changes the current service to a target service, control information necessary to detect the location of the target service in a frame and demodulate the target service can be acquired, and thus a service change can be made without reading a separate control channel.

主权项

1. A method of transmitting control information in a broadcast communication system, the method comprising the steps of:
generating service control information that includes information indicating a location of a target service within a frame and information necessary to demodulate the target service; constructing the frame by inserting, into a data part of the frame, data of the target service and the service control information; and transmitting the constructed frame, wherein the constructed frame comprises the data part and a control part separate from the data part, such that the data part is configured to include data of at least one current service and the separate control part is configured to include other control information corresponding to the at least one current service, and wherein the service control information is used for reception of the service at a receiver if the receiver changes from reception of a service from among the at least one current service to reception of the target service.
