Processing of invalid subframes of hybrid automatic repeat request (HARQ) process with disabled hybrid automatic repeat request (HARQ) feedback for long term evolution machine type communication (LTE-MTC) in downlink (DL) monitoring in non-terrestrial network (NTN) signaling

Abstract

A method, a network node and a wireless device are disclosed. At least one embodiment includes a network node configured to transmit at least one or both of a Machine Type Communication Physical Downlink Control Channel (MPDCCH) and a Physical Downlink Shared Channel (PDSCH) associated with a Hybrid Automatic Repeat Request (HARQ) process. The network node includes, when HARQ feedback of the HARQ process is disabled, avoiding or applying a scheduling restriction on transmitting at least one or both of the MPDCCH and the PDSCH within a predetermined period after the last PDSCH transmission, the predetermined period being several milliseconds, and wherein, after the predetermined period has elapsed, transmitting the at least one or both of the MPDCCH and the PDSCH with the scheduling restriction. A first or earliest subframe for another MPDCCH or PDSCH of the HARQ process that can be received by a wireless device (WD) is a low complexity coverage enhanced downlink (BL / CE DL) subframe with reduced bandwidth.
