The UE may sense sidelink control information (SCI) and measure associated reference signal received power (RSRP) from other UEs during a sensing period. During a selection period, the UE may autonomously select resources from a set of initial candidate resources. The UE may exclude resources that are likely to have interference based on associated RSRP of SCI from the sensing period.

Abstract: A base station can support dynamic spectrum sharing (DSS) between new radio (NR) services and Long Term Evolution (LTE) services. The base station can determine whether a NR physical downlink control channel (PDCCH) control resource set (CORESET) and a LTE PDCCH frequency range are partially overlapped in a frequency domain including a first frequency region and a second frequency region. The partial overlap occurs when the LTE PDCCH frequency range overlaps with the NR PDCCH CORESET in the first frequency region without overlapping with the NR PDCCH CORESET in the second frequency region. In response to a determination that the partial overlap occurs, the base station can map a NR PDCCH or a NR PDCCH demodulation reference signal (DMRS) to resource elements in the second frequency region, and map a LTE cell-specific reference signal (CRS) to a symbol carrying the LTE CRS in the first frequency region.

A user equipment (UE) may monitor a default search space set group (SSSG) for downlink control information (DCI) from a base station in the PDCCH.

The first non-default SSSG may be a non-empty SSSG including a search space set with at least one associated search space. The second non-default SSSG may be an empty SSSG with no associated search space to emulate PDCCH skipping.
