  • Publication number: 20190007961
    Abstract: A control resource region of an New Radio system slot structure may be separated into control resource sets, only some of which may be used for control transmissions. Aspects presented herein improve the efficient utilization of resources by enabling data transmission in resources of the DL control resource region and/or the UL control resource region. A UE receives an indication of a control resource set in a control resource region of a slot that may provide a control channel resource or a data channel resource and performs rate matching for data transmissions in the data channel based at least in part on the indication. The indication may be a semi-static indication, e.g., RRC signaling, of the control resource set.

Flexible interleaving may include dynamically or semi-statically determining a combination of bit-level, tone-level, tone-group level, or other interleaving technique for one or more transmissions. The interleaving configuration may be based on delay spread, a coherence bandwidth, a signal to noise ratio, a Doppler spread, or a combination thereof. An interleaving configuration may be a determination may be made by a base station or some other network entity and explicitly signaled to another device. Additionally or alternatively, the determination may be made based on one or more implicit rules, which may be based on a variety of factors (e.g., available bandwidth, modulation and coding scheme (MCS), code block (CB) size). Further, interleaving may be enabled (or disabled) under certain conditions.
