Abstract

It is provided a method, comprising instructing a first cell to transmit a first packet data unit to a terminal on a first active bandwidth part of a first carrier of the first cell in a first frame and to instruct a second cell to transmit a second packet data unit to the terminal on a second active bandwidth part of a second carrier of the second cell in a second frame; wherein the first and second bandwidth parts have first and second bandwidth part identifiers, respectively; if the first cell is the same as the second cell: the first and second bandwidth part identifiers are different from each other, and the first and second system frame numbers are the same; and if the first cell is different from the second cell: a frequency range of the first carrier is the same as the frequency range of the second carrier.

Dependent claims

An apparatus, comprising at least one processor, at least one memory including computer program code, and the at least one processor, with the at least one memory and the computer program code, being arranged to cause the apparatus to at least:

monitor if a first packet data unit for a terminal is received on a first active bandwidth part of a first carrier in a first frame having a first system frame number and a second packet data unit for the terminal is received on a second active bandwidth part of a second carrier in a second frame having a second system frame number;
and
instruct a processing device of the terminal to process at least one of the first packet data unit and the second packet data unit if the first packet data unit and the second packet data unit are received;
wherein
the first active bandwidth part has a first bandwidth part identifier;
the second active bandwidth part has a second bandwidth part identifier;
and
if the first carrier is the same as the second carrier:
the first bandwidth part identifier is different from the second bandwidth part identifier, and the first system frame number is the same as the second system frame number;
or
if the first carrier is different from the second carrier:
a frequency range of the first carrier is the same as a frequency range of the second carrier, wherein
the first bandwidth part identifier identifies a first frequency chunk of the first carrier;
and
the second bandwidth part identifier identifies a second frequency chunk of the second carrier;
if the first carrier is different from the second carrier at least one of the following conditions is fulfilled:
the first frequency chunk does not overlap the second frequency chunk;
and
the first system frame number is different from the second system frame number.
