Control frame format for WLAN
First Claim
1. A method for transmitting a control data unit in a wireless network, the method comprising:
- choosing, at a communication device;
(i) to send a request to send (RTS) data unit or a clear to send to self (CTS-to-self) data unit at a base channel bandwidth of 2 MHz, or(ii) to send the RTS data unit or the CTS-to-self data unit at a base channel bandwidth of 1 MHz;
generating, at the communication device, the RTS data unit or the CTS-to-self data unit at the chosen base channel bandwidth; and
causing the RTS data unit or the CTS-to-self data unit to be transmitted by the communication device such that the RTS data unit or the CTS-to-self data unit is duplicated to generate a transmission occupying a total channel bandwidth of 4 MHz, 8 MHz, or 16 MHz.

Abstract
In a method for transmitting a data unit in a wireless communication network, a physical layer (PHY) preamble and a media access control layer (MAC) header are generated. In generating the MAC header, a first address field to include a first address and a second address field to include a second address are generated. The first, not globally unique, address indicates a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The second address field indicates the other one of a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The first address field and the second address field are included in the MAC header. The MAC header omits a globally unique address corresponding to the first address of the first address field.

7. A communication device, comprising:
-
a network interface device having one or more integrated circuits configured to;
choose;(i) to send a request to send (RTS) data unit or a clear to send to self (CTS-to-self) data unit at a base channel bandwidth of 2 MHz, or (ii) to send the RTS data unit or the CTS-to-self data unit at a base channel bandwidth of 1 MHz; wherein the one or more integrated circuits are further configured to; generate the RTS data unit or the CTS-to-self data unit at the chosen base channel bandwidth, and transmit the RTS data unit or the CTS-to-self data unit such that the RTS data unit or the CTS-to-self data unit is duplicated to generate a transmission occupying a total channel bandwidth of 4 MHz, 8 MHz, or 16 MHz. - View Dependent Claims (8, 9, 10, 11, 12)

13. A tangible, non-transitory computer readable medium storing machine readable instructions that, when executed by a processor, cause the processor to:
-
choose; (i) to send a request to send (RTS) data unit or a clear to send to self (CTS-to-self) data unit at a base channel bandwidth of 2 MHz, or (ii) to send the RTS data unit or the CTS-to-self data unit at a base channel bandwidth of 1 MHz; cause a network interface device to generate the RTS data unit or the CTS-to-self data unit at the chosen base channel bandwidth, wherein the network interface device includes or is coupled to the processor; and cause the network interface device to transmit the RTS data unit or the CTS-to-self data unit such that the RTS data unit or the CTS-to-self data unit is duplicated to generate a transmission occupying a total channel bandwidth of 4 MHz, 8 MHz, or 16 MHz. - View Dependent Claims (14, 15, 16, 17, 18)
