AVOIDING EXTENDED INTERFRAME SPACE

摘要

Methods, systems, and devices are described for avoiding extended interframe space (EIFS) in a wireless local area network (WLAN). A wireless device may transmit a message during a transmit opportunity (TXOP) that includes a first portion transmitted at a first data rate and a second portion transmitted at a second rate that is higher than the first. The wireless device may then transmit a terminating message at the first data rate. The wireless device may also receive a second message prior to transmitting the terminating message. The terminating message may be a clear-to-send message (CTS) or an acknowledgement (ACK) message. The first message may be an aggregate media access control packet data unit (A-MPDU) in which the first portion is a preamble and the second portion is an MPDU.

主权项

1. A method of wireless communication comprising:
transmitting a first message during a transmit opportunity (TXOP), wherein the first message comprises a first portion transmitted at a first data rate and a second portion transmitted at a second data rate that is higher than the first data rate; and transmitting a terminating message at the first data rate.
