Abstract

An example method is performed by a wireless device in a wireless communication network. The method comprises receiving, from a base station, a control message allocating resources in a bandwidth part for a downlink transmission, the bandwidth part including unlicensed spectrum and being divided into a plurality of bandwidth pieces corresponding to bandwidth units over which listen-before-talk (LBT) is performed. The radio resources used for the downlink transmissions exclude (e.g., by puncturing or rate-matching around) one or more guard bands of a bandwidth piece that is sensed as free for transmission.
