PDCCH monitoring reduction associated with WTRU power saving
The WTRU may monitor for a downlink transmission in a first monitoring occasion of a first search space. The first monitoring occasion of the first search space may be associated with a first monitoring occasion pattern. The WTRU may monitor for the downlink transmission in a second monitoring occasion of a second search space. The second monitoring occasion of the second search space may be associated with a second monitoring occasion pattern. The first search space and the second search space may belong to a search space subset. The WTRU may receive the downlink transmission in the second monitoring occasion of the second search space. The downlink transmission may include a skipping indication. Based on the WTRU receiving the skipping indication in the downlink transmission in the second monitoring occasion of the second search space, the WTRU may apply skipping to the second search space and the first search space.
