Mobility communication using mid-ambles
First Claim
1. An apparatus for communication, comprising:
- a processing system configured to;
generate a physical layer protocol data unit (PPDU) for Wi-Fi communication comprising a plurality of mid-ambles, a Number of High Efficiency Long Training Field (HE-LTF) Symbols field, and a Doppler bit set to a value of 1, andrepurpose at least one bit of the Number of HE-LTF Symbols field to carry mid-amble update interval information; and
an interface configured to output the data unit for transmission.

Abstract
Various aspects of the disclosure relate to communication using a data unit that includes at least one mid-amble. In some aspects, an apparatus may use mid-ambles for mobility scenarios (e.g., when the apparatus is moving outdoors). The disclosure relates in some aspects to signaling associated with the use of mid-ambles. In some aspects, an apparatus may signal whether it supports sending and/or receiving data with mid-ambles. In some aspects, an apparatus may signal whether a particular data unit includes at least one mid-amble. In some aspects, an apparatus may signal an indication of at least one mid-amble update interval. In some aspects, an apparatus may signal whether a mid-amble includes a short training field.
