Abstract
A method and device for communicating in a contention-based communication network. According to an embodiment, the method includes obtaining, by a transmitter, an access to a channel during a transmission opportunity (TXOP) and transmitting, by the transmitter, a contention free (CF)-End frame to truncate the TXOP if the transmitter has no more data that the transmitter can send that fits within the TXOP, wherein the CF-End frame includes a duration field indicating a time required to complete the truncation of the TXOP.

A method for communicating in a contention-based communication network, the method comprising:
- obtaining, by a transmitter, an access to a channel during a transmission opportunity (TXOP);
- and
- transmitting, by the transmitter, a contention free (CF)-End frame to truncate the TXOP if the transmitter has no more data that the transmitter can send that fits within the TXOP,
- wherein the CF-End frame includes a duration field indicating a time required to complete the truncation of the TXOP, and
- wherein a value k of the duration field is computed as:
- k=(i−1)×(tcf+s)
- where i denotes 1, 2 or 3, tcf denotes a transmission time of the CF-End frame and s denotes a Short Inter-Frame Space (SIFS).
A transmitter comprising:
- a radio frequency unit configured to transmit a radio signal;
- and
- a processor operably coupled with radio frequency unit and configured to:
- obtain an access to a channel during a transmission opportunity (TXOP);
- and
- instruct the radio frequency unit to transmit a contention free (CF)-End frame to truncate the TXOP if the apparatus has no more data that the apparatus can send that fits within the TXOP,
- wherein the CF-End frame includes a duration field indicating a time required to complete the truncation of the TXOP, and
- wherein a value k of the duration field is computed as:
- k=(i−1)×(tcf+s)
- where i denotes 1, 2 or 3, tcf denotes a transmission time of the CF-End frame and s denotes a Short Inter-Frame Space (SIFS).
