Network node and method in a wireless communications network

A network node configurable to decide a feedback option of a message sent between the network node and a User Equipment (UE) in a wireless communication network, the message comprising a first data punctured by a second data, wherein the first data is sent in a slot of a radio bearer and the second data is sent a mini-slot of the radio bearer, and wherein the mini-slot is smaller than the slot, the network node comprising:

• at least one processor;
• and
• at least one memory storing computer-executable instructions that, when executed by the at least one processor, configure the network node to:
• decide a feedback option for feedback that is to be sent to the sender of the message, wherein deciding is based on at least one of:
• slot control resource capacity, mini-slot control resource capacity, and requirements of the radio bearer, and wherein the feedback option is decided from among the following options:
• (1) only a slot-based channel is used for feedback pertaining to both the first data and the second data;
• (2) a mini-slot-based channel is used for feedback pertaining to the second data and a slot-based channel is used for feedback pertaining to the first data;
• and
• (3) only a mini-slot-based channel is used for feedback pertaining to both the first data and the second data.
