Communication of high efficiency (HE) long training fields (LTFS) in a wireless local area network (WLAN)
A mobile station may determine streams associated with a high efficiency (HE) wireless local area network (WLAN) communication. A number of symbols related to the streams may be utilized for HE long training field (LTF) communication.
1. A mobile station comprising:
a processor; and
a transmitter
the processor configured to determine a number of symbols utilized for high efficiency (HE) long training field (LTF) based on a number of space-time streams associated with a HE wireless local area network (WLAN) communication,
wherein the number of space-times streams is at least two,
wherein, on a condition that the number of space-time streams is equal to 2, 4, 6, or 8, the processor determines the number of symbols is equal to the number of space-time streams,
wherein, on a condition that the number of space-time streams is not equal to 2, 4, 6, or 8, the processor determines the number of symbols is a next higher number than the number of space-time streams,
the transmitter configured to transmit the HE LTF communication using a set of subcarriers associated with the number of space-time streams.
2. The station of claim 1 , wherein the number of space-time streams is a total number of space-time streams for multi-user multiple-input multiple-output (MU MIMO) users.
3. The station of claim 1 , wherein the processor is further configured to determine a group identifier and identify a position of a device in a group associated with the group identifier.
4. The station of claim 1 , wherein the HE LTF communication is part of a HE physical protocol data unit (PPDU).
5. A method comprising:
determining, by a mobile station, a number of symbols utilized for high efficiency (HE) long training field (LTF) based on space-time streams associated with a HE wireless local area network (WLAN) communication,
wherein the number of space-times streams is at least two,
wherein, on a condition that the number of space-time streams is equal to 2, 4, 6, or 8, the processor determines the number of symbols is equal to the number of space-time streams,
wherein, on a condition that the number of space-time streams is not equal to 2, 4, 6, or 8, the processor determines the number of symbols is a next higher number than the number of space-time streams, and
transmitting, by the mobile station, the HE LTF communication using a set of subcarriers associated with the number of space-time streams.
6. The method of claim 5 , wherein the number of space-time streams is a total number of space-time streams for multi-user multiple-input multiple-output (MU MIMO) users.
7. The method of claim 5 , further comprising determining a group identifier and identifying a position of a device in a group associated with the group identifier.
8. The method of claim 5 , wherein the HE LTF communication is part of a HE physical protocol data unit (PPDU).
