Embodiment Construction

[0073] Hereinafter, some embodiments of the present invention are described in detail with reference to the accompanying drawings, in which features of the embodiments can be freely combined with each other unless otherwise described. It is to be clearly understood, however, that the description of certain embodiments is given by way of example only, and it is in no way intended to be construed as limiting the invention to the disclosed details.

[0074] Also, it is to be understood that an apparatus is configured to perform a corresponding method, although in some cases only an apparatus or only a method is described.

[0075] As FDD agrees, discarding ACK / NACK feedback is trivial. However, since the probability of successful decoding is usually 90%, dropping is not an effective solution, since the gNB has to schedule redundant HARQ retransmissions for all affected DL HARQ processes.

[0076] If the agreed-upon FDD drop solution is adopted for TDD, there will be another prob...

Abstract

It is provided a method, comprising checking whether or not a downlink control information comprises a trigger to perform a bandwidth part switch, wherein the downlink control information schedules anuplink transmission of a first acknowledgment in a first uplink control information; determining a second acknowledgment, wherein an uplink transmission of the second acknowledgment is scheduled in or after a predefined transition period after the downlink control information; monitoring, if the downlink control information comprises the trigger and if the second acknowledgment is determined, whether or not the uplink transmission of the second acknowledgment is received in the first uplink control information.
