Robust bwp approaches to mitigate the impact of high power narrow-band interferer

Abstract

Methods and apparatuses are described herein for robust bandwidth part (BWP) approaches to mitigate the impact of high power narrow-band interference. For example, a wireless transmit/receive unit (WTRU) may receive, from a base station (BS), configuration information indicating a plurality of initial bandwidth parts (BWPs). The plurality of initial BWPs may comprise a first initial BWP and a second initial BWP. The first initial BWP and the second initial BWP may be separated from each other in a frequency domain to avoid interference on at least one of the plurality of initial BWPs. The WTRU may send, based on failure to decode a transmission received in the first initial BWP, to the BS, an uplink transmission using the second initial BWP. The uplink transmission may include one or more preambles that are sent using a physical random access channel (PRACH).
