Abstract
A wireless device provided according to an aspect of the present invention first operates as an access point (AP) and transmits instructions which instruct associated stations to desist from transmitting data packets to the AP. According to another aspect, the instructions correspond to CTS-to-self signal, but the AP also desists from transmission of data packets in the desist duration. According to another aspect, the wireless device operates as a station in the desist duration and switches back as an AP after end of the desist duration. In an embodiment, the station scans for other APs/stations in the communication range, and associates with one of such APs also.
Claims20
A method of operating a wireless device, said method comprising:
- transmitting, on a wireless medium, a CTS-to-self signal specifying a duration, said CTS-to-self signal being sent at a first time instance;
- and
- desisting from further transmissions on said wireless medium for said duration after said first time instance upon said transmitting of said CTS-to-self signal.
A non-transitory machine readable medium storing one or more sequences of instructions for causing an access point (AP) to communicate with stations in a Wireless Local Area Network (WLAN), wherein execution of said one or more sequences of instructions by one or more processors contained in said AP causes said access point to perform the actions of:
- transmitting a first signaling message of a first type, wherein messages of said first type are designed to reserve a channel on said WLAN for a duration specified in the corresponding message, wherein said first signaling message specifies a first duration to reserve said channel for said first duration following transmission of said first signaling message;
- sending a first data packet in said duration on said channel reserved for said duration;
- transmitting a second signaling message of said first type specifying a second duration to reserve said channel on said WLAN for said second duration;
- and
- desisting from transmitting data packets in said second duration in normal course.
A method of operating a wireless device in a Wireless Local Area Network (WLAN), said method comprising:
- operating said wireless device as an access point (AP);
- transmitting, by said AP on a wireless medium at a time instance, an instruction instructing wireless stations of said WLAN to desist from transmitting for a duration;
- operating said wireless device as a station in said duration after said time instance.
