Abstract
The present invention relates to a wireless communication data transmission method considering the number of terminals requesting services. The present invention provides a wireless communication base station for use in a network where a multicast service is received from a network entity and is provided to at least one or more terminals in contention-based channel access mode of a wireless communication. The base station comprises a storage unit for storing terminal information including the number of terminals which have joined the multicast service, and a priority determining unit for setting a user priority of a data frame to be transmitted using the terminal information. According to the present invention, a priority of data to be transmitted is determined in consideration of the number of serviced terminals, and thus, the data can be reasonably transmitted.
