Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine that a threshold is satisfied with regard to a search space set mapping, for a plurality of search space sets, for a slot of a downlink control channel, wherein the threshold relates to at least one of: a slot-based control channel element limit, or a slot-based blind decode limit; and perform a mapping of or monitor a subset of search space set occasions, of a search space set of the plurality of search space sets, in the slot in connection with determining that the threshold is satisfied. Numerous other aspects are provided.

Abstract: Aspects of frequency error detection with Physical Broadcast CHannel (PBCH) frequency hypothesis are described. For example, a method and apparatus are disclosed for frequency tracking in a user equipment (UE) may include detecting a change in frequency that exceeds a pull-in range of a frequency tracking loop (FTL) of the UE. The method and apparatus may also include identifying a tracking recovery frequency in response to the change in frequency being detected, wherein the tracking recover frequency is identified from a set of frequency hypotheses and based on decoding of the PBCH received by the UE. The method and apparatus may further include updating the FTL with the tracking recovery frequency.
