Abstract: Disclosed is a method in which a base station that supports multiple carriers transmits a paging message. The base station determines a first time for transmitting information associated with a multicast broadcast service (MBS), and transmits the information associated with an MBS at the first time via a first carrier. The base station determines a second time for transmitting a paging message to a mobile station, determines a second carrier for transmitting the paging message to the mobile station, and transmits the paging message at the second time via the second carrier. The second time is different from the first time.

Abstract: The present invention relates to a method for sending/receiving data in a wireless packet communication and more particularly a short-distance wireless communication system, when one terminal is attempting to communicate with various terminals simultaneously. A method of the present invention, in which a sending terminal sends data to a plurality of receiving terminals, comprises the steps of: determining the data item having the maximum length from among different items of data to be sent to the plurality of receiving terminals; acquiring length information about the data item having the maximum length; generating a signal field containing length information about the data item having the maximum length; and sending the signal field to the plurality of receiving terminals. The present invention has the advantageous effect that it can ensure that zones where reception is not possible are not created and smooth communication is possible when a single terminal uses various communications pathways to simultaneously transmit data to various terminals and receive an Ack thereto.
