Abstract
Methods, apparatuses, and a computer program are presented for determining a reservation period for data transmission in a wireless communication network. The duration of the reservation period is determined on the basis of RTS/CTS handshake between a transmitter and a receiver apparatus.
Claims21
1-27. (canceled)
A method, comprising:
- causing the wireless communication apparatus to transmit a transmission request message to a second wireless communication apparatus on a plurality of channels, wherein the transmission request message is used to query whether or not at least one of said plurality of channels is free, and wherein the transmission request message triggers a first reservation period to said plurality of queried channels;
- receiving a transmission response message as a response to the transmission request message, wherein the transmission response message indicates at least one channel the second wireless communication apparatus has detected to be free;
- determining the duration of a second reservation period on the basis of the received transmission response message, wherein the second reservation period extends to cover data transmission;
- and
- causing the wireless communication apparatus to reserve said at least one channel detected to be free for the second reservation period and to transmit data during the second reservation period.

A method, comprising:
- receiving, in a wireless communication apparatus, a transmission request message on at least one channel, wherein the transmission request message is used to query whether or not at least one of a plurality of channels queried with the transmission request message is free, and wherein the transmission request message triggers a first reservation period to said plurality of channels;
- determining the duration of a second reservation period, wherein the second reservation period extends to cover a data transmission and is longer in a case where at least one of said plurality of queried channels is detected not to be free than in a case where said plurality of queried channels are all detected to be free;
- causing the wireless communication apparatus to transmit a transmission response message as a response to the transmission request message, wherein the transmission response message indicates at least one channel detected to be free.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- cause a first wireless communication apparatus to transmit a transmission request message to a second wireless communication apparatus on a plurality of channels, wherein the transmission request message is used to query whether or not at least one of said plurality of channels is free, and wherein the transmission request message triggers a first reservation period to said plurality of queried channels;
- receive a transmission response message as a response to the transmission request message, wherein the transmission response message indicates at least one channel the second wireless communication apparatus has detected to be free;
- determine the duration of a second reservation period on the basis of the received transmission response message, wherein the second reservation period extends to cover data transmission;
- and
- cause the first wireless communication apparatus to reserve said at least one channel detected to be free for the second reservation period and to transmit data during the second reservation period.
