METHOD AND APPARATUS FOR ALLOCATING BANDWIDTH OF WIRELESS NETWORK, AND METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA ON THE NETWORK
First Claim
1. A method of transmitting data in a wireless network, comprising:
- causing at least one wireless device that belongs to the wireless network to transmit a first frame to a network coordinator, wherein the first frame comprises information indicating a transmission mode for transmitting the data, and is used to request a time slot;
receiving a beacon frame comprising information about the transmission mode and a time slot duration from the network coordinator; and
transmitting the data in the transmission mode to other wireless devices that belong to the wireless network during the time slot duration,wherein the transmission mode indicates whether the data is transmitted by a wide-band signal or a narrow-band signal.
