Abstract
The present invention concerns a communication method in a wireless communication network, wherein the method comprises at a station: sending to an access point station a frame comprising a buffer status report reporting an amount of buffered data to be transmitted; receiving, from the access point station, an allocation of a resource unit for the transmission of the buffered data; and transmitting the buffered data in the allocated resource unit; wherein the frame sent to the access point station further comprises a time indication representative of a time limit for the transmission of the buffered data by the station.
Claims22
A communication method in a wireless communication network, wherein the method comprises at a station:
- sending to an access point station a frame comprising a buffer status report reporting an amount of buffered data to be transmitted;
- receiving, from the access point station, an allocation of a resource unit for the transmission of the buffered data;
- and
- transmitting the buffered data in the allocated resource unit;
- wherein the frame sent to the access point station further comprises a time indication for the transmission of the buffered data by the station,
- wherein the buffer status report comprises:
- an identifier indication identifying a type of the buffered data;
- and
- a buffer status report duration unit indication identifying a time unit used to express the time indication;
- and wherein, if the amount of the buffered data is not zero, the time indication is representative of a time limit for the transmission of the buffered data by the station and wherein the resource unit is allocated prior to the time limit.
A communication method in a wireless communication network, wherein the method comprises at an access point station:
- receiving, in a frame sent by a station, a buffer status report reporting an amount of buffered data to be transmitted by the station;
- and
- transmitting to the station an allocation of a resource unit for the transmission of the buffered data;
- wherein the frame sent by the station, and comprising the buffer status report, further comprises a time indication,
- wherein the resource unit is allocated based on the received time indication,
- wherein the buffer status report comprises:
- an identifier indication identifying a type of the buffered data;
- a buffer status report duration unit indication identifying a time unit used to express the time indication;
- and
- wherein, if the amount of the buffered data is not zero, the time indication is representative of a time limit for the transmission of the buffered data by the station and
- wherein the resource unit is allocated prior to the time limit.
A station in a wireless communication network, wherein the station comprises a processor configured for:
- sending to an access point station a frame comprising a buffer status report reporting an amount of buffered data to be transmitted;
- receiving, from the access point station, an allocation of a resource unit for the transmission of the buffered data;
- and
- transmitting the buffered data in the allocated resource unit;
- wherein the frame sent to the access point station further comprises a time indication for the transmission of the buffered data by the station,
- wherein the buffer status report comprises:
- an identifier indication identifying a type of the buffered data;
- and
- a buffer status report duration unit indication identifying a time unit used to express the time indication;
- and
- wherein, if the amount of the buffered data is not zero, the time indication is representative of a time limit for the transmission of the buffered data by the station and
- wherein the resource unit is allocated prior to the time limit.
An access point station in a wireless communication network, wherein the access point station comprises a processor configured for:
- receiving, in a frame sent by a station, a buffer status report reporting an amount of buffered data to be transmitted by the station;
- and
- transmitting to the station an allocation of a resource unit for the transmission of the buffered data;
- wherein the frame sent by the station, and comprising the buffer status report, further comprises a time indication,
- wherein the resource unit is allocated based on the received time indication,
- wherein the buffer status report comprises:
- an identifier indication identifying a type of the buffered data;
- a buffer status report duration unit indication identifying a time unit used to express the time indication;
- and
- wherein, if the amount of the buffered data is not zero, the time indication is representative of a time limit for the transmission of the buffered data by the station and
- wherein the resource unit is allocated prior to the time limit.
A method comprising
- generating and sending a frame designed to be sent by a station of a wireless communication network to an access point station, the frame comprising a buffer status report field reporting an amount of buffered data to be transmitted by the station,
- wherein the frame further comprises a time indication field for the transmission of the buffered data by the station or of a time limit until which an allocation of resource unit is not needed by the station,
- wherein the buffer status report comprises:
- an identifier indication identifying a type of the buffered data;
- a buffer status report duration unit indication identifying a time unit used to express the time indication;
- and
- wherein, if the amount of the buffered data is not zero, the time indication is representative of a time limit for the transmission of the buffered data by the station and
- wherein the resource unit is allocated prior to the time limit.
