Method of communication between mobile station and base station in mobile communication system
Method of communication between a mobile station and a base station in a mobile communication system of IMT-2000 communication network basis, which is suitable for effective transmission of various multimedia information within a given channel capacity, the method including the steps of (1) when a mobile station receives a data transmission request, providing one portion of a period of a data frame with regular number and arrangement of down link slots and up link slots and the other portion of the data frame with irregular number and arrangement of down link slots or/and up link slots depending on characteristics and amount of subscriber data to be transmitted, (2) determining a transmission type according to which a communication is executed using a competition period for determining priorities of the subscriber data, a reservation period for making a reservation for time slots for use in transmission of the subscriber data, and an assignment period for assigning a memory period according to an amount of the subscriber data, which periods are selectively and respectively included in the one portion of the data frame and in the other portion of the data frame, and (3) providing the data frame according to the transmission type and transmitting to the base station.
1. A method for transmitting a data frame and a control frame transmitted from a mobile station to a base station via uplink, the method comprising:
transmitting the data frame to the base station at one transmission opportunity, wherein the data frame comprises a header portion and a data portion, and wherein the header portion comprises:
a first field to indicate to the base station whether or not the data frame has a time resource request while data in the data portion is transmitted simultaneously, the first field having either a first logic value or a second logic value, the first field having the first logic value when the data frame has the time resource request, and
a second field to contain an amount of time resource required when the first field has the first logic value; and
receiving a plurality of data frames transmitted from the base station; and
transmitting the control frame to the base station, wherein the control frame has an acknowledgement field indicating a reception status of the received plurality of data frames transmitted from the base station, wherein the control frame is transmitted separately from the data frame to the base station.
2. The method of claim 1 , wherein the acknowledgement field comprises a bitmap, each bit of the bitmap indicating whether the corresponding data frame among the plurality of data frames is successfully received or not.
3. A mobile station for transmitting a data frame and a control frame to a base station via uplink, the mobile station comprising:
a receiver for receiving a plurality of data frames generated at the base station;
a generator configured to form a data frame and a control frame, wherein the data frame comprises a header portion and a data portion, and wherein the header portion comprises:
a first field to indicate to the base station whether or not the data frame has a time resource request while data in the data portion is transmitted simultaneously, the first field having either a first logic value or a second logic value, the first field having the first logic value when the data frame has the time resource request, and
a second field to contain an amount of time resource required when the first field has the first logic value,
wherein the control frame has an acknowledgement field indicating a reception status of the received plurality of data frames generated at the base station; and
a transmitter for transmitting the data frame and the control frame to the base station at different transmission opportunities from each other.
4. The mobile station of claim 3 , wherein the
acknowledgement field comprises a bitmap, each bit of the bitmap indicating whether the corresponding data frame among the plurality of data frames is successfully received or not.
