US 2018/0020435 A1 · METHOD AND APPARATUS FOR SCHEDULING USER EQUIPMENT UPLINK TRANSMISSIONS ON AN UNLICENSED CARRIER

Abstract

A method and apparatus schedule user equipment uplink transmissions on an unlicensed carrier. An uplink grant can be sent. The uplink grant can include a field regarding a sounding reference signal transmission of a subframe. The sounding reference signal can be received in an initial discrete Fourier transform spread orthogonal frequency division multiplexing symbol of the subframe. A physical uplink shared channel can be received in at least a portion of a remaining part of the subframe. The remaining part of the subframe can occur later than the initial discrete Fourier transform spread orthogonal frequency division multiplexing symbol.
