Title:
RADIO NODE AND METHODS IN A WIRELESS COMMUNICATIONS NETWORK
Document Type and Number:
WIPO Patent Application WO/2019/139516
Kind Code:
A1
Abstract:
A method performed by a radio node for handling a Hybrid Automatic Repeat Request (HARQ) process is provided. The radio node obtains (402) an indication of an unfinished HARQ process at an occurrence of a switch. The switch is to be performed by a User Equipment, UE. The switch relates to any one out of: a switch from a first carrier to a second carrier, a switch from a first cell to a second cell, and a switch from a first bandwidth part to a second bandwidth part. When it is determined that the unfinished HARQ process will not be continued after the switch, the radio node decides (406) to trigger any option out of: - Option 1: triggering Radio Link Control, RLC, retransmissions of Protocol Data Units, PDUs, corresponding to the unfinished HARQ process to be performed after the switch has occurred, and - Option 2: triggering proactively scheduled retransmissions on HARQ,
