1. A method for operating a user equipment (UE) in a radio access network (RAN), the method comprising:
transmitting signaling on a Physical Uplink Control CHannel (PUCCH) resource structure and on a Physical Uplink Shared CHannel (PUSCH) resource structure:
the PUCCH resource structure covering a PUCCH time interval and a plurality of PUCCH frequency intervals;
the PUSCH resource structure covering a PUSCH time interval and a plurality of PUSCH frequency intervals;
during at least for a part of the PUCCH time interval, the PUCCH resource structure being adjacent to the PUSCH resource structure in the frequency domain along a frequency border between the PUCCH resource structure and the PUSCH resource structure;
for a part of the plurality of PUSCH frequency intervals, the PUCCH resource structure being adjacent to the PUSCH resource structure in the time domain along a time border between the PUCCH resource structure and the PUSCH resource structure; and
the PUCCH resource structure being modified to avoid collision with transmission of a demodulation reference signal (DM-RS), the modification including the PUCCH resource structure being split or a combination of split and at least one of shifted and shortened.
