Physical (PHY) layer communications
This disclosure provides methods, devices and systems for communicating over a 60 GHz band and reusing legacy hardware for communication over sub-6 bands. Certain aspects are directed to outputting, for transmission to a second wireless device, a first packet, wherein the first packet is output via a radio frequency (RF) front end defined by a first clock accuracy requirement having an acceptable error rate that is lower than a legacy clock accuracy requirement, and wherein the first packet is output for transmission via a first band. Certain aspects are directed to obtaining, from the second wireless device, a second packet via the first band.

obtain, from the wireless device, a second packet via the first band.
2 . The apparatus of claim 1 , wherein the first band is a 60 gigahertz frequency band.
3 . The apparatus of claim 1 , wherein a legacy clock accuracy requirement is ±20 parts-per-million (PPM), and wherein a first clock accuracy requirement is ±1 PPM.
4 . The apparatus of claim 1 , wherein a legacy clock accuracy requirement is a requirement of at least one of Institute of Electrical and Electronics Engineers (IEEE) 802.11ad, 802.11ax, 802.11ay, or 802.11be.
5 . The apparatus of claim 1 , wherein the first packet is output for transmission via an orthogonal frequency division multiplex (OFDM) physical layer (PHY) of at least one of Institute of Electrical and Electronics Engineers (IEEE) 802.11ad, 802.11ax, 802.11ay, or 802.11be.
6 . An apparatus for wireless communication, comprising:
one or more memories comprising instructions; and
one or more processors configured to execute the instructions and cause the apparatus to:
transmit a first packet to a second wireless device, wherein the first packet is transmitted via a radio frequency (RF) front end defined by a first clock accuracy having a configured error rate that is lower than a legacy clock accuracy, and wherein the first packet is transmitted via a first band; and
receive via the first band, a second packet from the second wireless device.
7 . The apparatus of claim 6 , wherein the first band is a 60 gigahertz frequency band.
8 . The apparatus of claim 6 , wherein a legacy clock accuracy requirement is ±20 parts-per-million (PPM), and wherein a first clock accuracy requirement is ±1 PPM.
