Access point AP, station STA, communications system, and data transmission method
First Claim
1. A station (STA), comprising:
- a transmitter configured to;
send a first request to send (RTX) when the STA obtains at least a first channel by contention; and
send a third RTX when the STA obtains, by listening, a second RTX from a second STA obtaining at least one channel by contention,wherein the second STA satisfies a set of conditions, andwherein the set of conditions comprises;
the second STA has buffer data to be transmittedthe second STA is in a same basic service set (BSS) as the STA obtaining the at least first channel by contention, anda power of a signal received from the STA obtaining the at least first channel by contention is greater than a preset threshold; and
a receiver coupled to the transmitter and configured to receive response information from an access point (AP), and wherein the response information can be used to schedule the STA to transmit data on a specified sub-channel.

Abstract
A data transmission method includes sending, by a master station (STA), a request to send (RTX) to an access point (AP) in a same basic service set (BSS), which includes the AP and multiple STAs, and the master STA is a STA that is the first to obtain a channel by contention in the multiple STAs, instructing a surrounding STA to determine, according to conditions, whether to follow the master STA to send an RTX, where a STA following the master STA to send the RTX satisfies conditions that the STA has buffer data to be transmitted, the STA is in the same BSS as the master STA, and a power of a signal received from the master STA is greater than a preset threshold, and receiving response information from the AP to transmit uplink data on a specified sub-channel.

9. An access point (AP), comprising:
-
a receiver configured to; receive a request to send (RTX) from a master station (STA) in a same basic service set (BSS) as the AP, wherein the master STA is a STA obtaining at least one channel by contention in the BSS; and receive an RTX from a follower STA of the master STA, wherein the follower STA satisfies conditions as follows; the follower STA has buffer data to be transmitted; the follower STA is in the same BSS as the master STA, and a power of a signal received from the master STA is greater than a preset threshold; and a transmitter coupled to the receiver and configured to send response information after RTXs from the master STA and the follower STA of the master STA are received. - View Dependent Claims (10, 11, 12)
