Abstract:
A communication device receives a first physical layer (PHY) data unit via a communication channel. The first PHY data unit corresponds to a trigger frame, and includes: a first PHY preamble having a legacy portion and a non-legacy portion, a first training field that includes a first training signal having a periodicity LP, and a second training field that includes a second training signal having the periodicity LP. The communication device generates a second PHY data unit. The second PHY data unit includes: a second PHY preamble that includes a third training field that includes a third training signal, and a fourth training field that includes a fourth training signal having a periodicity 2*LP. Generating the second PHY data unit comprises: modulating the third training field using a first tone spacing LTS between adjacent OFDM tones, and modulating the fourth training field using a second tone spacing equal to LTS/4 between adjacent OFDM tones.

Claim (Index 11):
An apparatus, comprising:\n a network interface device having one or more integrated circuit (IC) devices configured to:\n receive a first physical layer (PHY) data unit via a communication channel, wherein the first PHY data unit corresponds to a trigger frame that is configured to prompt the network interface device to transmit a second PHY data unit in response to receiving the first PHY data unit, wherein the first PHY data unit includes:\n a first PHY preamble having a legacy portion and a non-legacy portion, \n a first training field in the legacy portion of the first PHY preamble, wherein the first training field is for packet detection and for automatic gain control (AGC) adjustment, and wherein the first training field includes a first training signal having a periodicity L P , and \n a second training field in the non-legacy portion of the first PHY preamble, wherein the second training field includes a second training signal having the periodicity L P ; \n \n wherein the one or more IC devices are further configured to:\n generate the second PHY data unit, wherein the second PHY data unit includes:\n a second PHY preamble having a legacy portion and a non-legacy portion, \n a third training field in the legacy portion of the second PHY preamble, wherein the third training field is for packet detection and for AGC adjustment, and wherein the third training field includes a third training signal, and \n a fourth training field in the non-legacy portion of the second PHY preamble, wherein the fourth training field includes a fourth training signal having a periodicity 2*L P ; \n \n wherein generating the second PHY data unit comprises:\n modulating the third training field using a first tone spacing L TS  between adjacent OFDM tones, and \n modulating the fourth training field using a second tone spacing equal to L T /4 between adjacent OFDM tones; and \n wherein the one or more IC devices are further configured to transmit the second PHY data unit in response to the first PHY data unit.
