Abstract: Accordingly, systems and methods for managing power when the number of training and data tones are increased in a wireless communications system are provided. An L-SIG field is generated that includes a set of data and pilot tones, wherein the pilot tones are inserted between the data tones in the set of data and pilot tones. A plurality of training tones is added to the L-SIG field before and after the set of data and pilot tones. A symbol is generated that includes the L-SIG field, an L-LTF field, and a data field, wherein the training tones of the L-SIG field provide channel estimates for the data field. Power of the L-LTF field is managed relative to power of the L-SIG field in the generated symbol in a time domain.

Abstract: A method for transmitting a first field and one or more second fields is described. A number of devices in a group of multiple devices to which a first OFDMA data unit is to be transmitted is selected. A block allocation that indicates respective integer numbers of different tone blocks of a WLAN communication channel to be assigned to each device in the group of multiple devices is selected. A first field is encoded to indicate both the selected number of devices in the group and the selected block allocation. One or more second fields are encoded to indicate a respective device identifier for each device in the group of multiple devices. The first field and the one or more second fields are transmitted to each device in the group of multiple devices.

Abstract: A method includes determining a first measure of a benefit of disallowing transmission during a time period within a time frame. The benefit of disallowing transmission includes an immediate benefit of disallowing transmission during the time period, and a future benefit of having, for use in a subsequent portion of the time frame, a decremented number of opportunities to disallow transmission. The method also includes determining a second measure of a benefit of not disallowing transmission during the time period. The benefit of not disallowing transmission includes an immediate benefit of not disallowing transmission during the time period, and a future benefit of having, for use in the subsequent portion of the time frame, a non-decremented number of opportunities to disallow transmission. The method also includes determining whether to disallow transmission during the time period at least in part by comparing the first measure to the second measure.

Abstract: Systems and techniques relating to repeated signal detection are described. A described technique includes receiving a signal including first and second portions, the first portion includes first and second symbols; performing a determination, based on a first decision metric component and a second decision metric component, of whether the second symbol is a repeated version of the first symbol, the first decision metric component contributing to the determination that the second symbol is the repeated version of the first symbol, and the second decision metric component contributing to the determination that the second symbol is not the repeated version of the first symbol; and decoding the second portion of the signal in accordance with a first format or a second format. The first format is used if the first symbol is not repeated. The second format is used if the first symbol is repeated.

Abstract: A physical layer (PHY) preamble is generated, the PHY preamble defined by a first wireless communication protocol and including a first portion that corresponds to a legacy PHY preamble defined by a second, legacy wireless communication protocol. The PHY preamble also includes a second portion that is defined by the first wireless communication protocol. Error detection information is generated using a first field in the first portion of the PHY preamble. The second portion of the PHY preamble is generated to include the error detection information in a second field. The PHY data unit is generated so that the PHY data unit includes the PHY preamble.

Abstract: A wireless device including a first receiver and a second receiver. The first receiver is configured to receive a first signal transmitted on a first network using a first communication standard, and generate, in response to a signal strength of the first signal being greater than or equal to a predetermined threshold, first information about the first signal based on a first portion of the first signal. The second receiver is configured to receive a second signal transmitted on a second network using a second communication standard, and suppress interference from the first signal based on the first information about the first signal. The first communication standard is different from the second communication standard. The first receiver and the second receiver are co-located in the wireless device.
