5g Dl Channel Deep Dive Into Physical Downlink Control Channe This video covers most of the related aspects of the 5g physical downlink control channel. the below is covered in this video.content:1 pdcch main function2. Downlink physical channels. 5g nr physical broadcast channel (pbch), physical downlink shared channel (pdsch), and physical downlink control channel (pdcch) physical channels correspond to a set of time frequency resources used for transmission of particular transport channel data, control information, or indicator information.

In 5g nr (new radio), the physical downlink control channel (pdcch) plays a critical role in the control of downlink resource allocations, scheduling, and signaling for ues (user equipment). it is responsible for carrying dci (downlink control information), which informs ues about the configuration of the pdsch (physical downlink shared channel. Ii. pdcch physical layer structure a. channel coding and downlink control information (dci) construction the information carried by the pdcch is referred to as dci. dci contains the scheduling information for the ul or dl data channels and other control information for one ue or a group of ues. further details regarding dci are provided in section. An overview of the 5g new radio (nr) physical downlink control channel (pdcch) design of 3gpp release 15 is presented and performance enhancements are proposed. a novel pdcch hash function is shown to outperform the legacy hash function by about one order of magnitude in terms of inter user blocking probability while maintaining the frequency selective scheduling capability for downlink.
