Splet18. mar. 2016 · PDCCH ( Physical downlink Control Channel ) :- This channel carries the control information about the data being transmitted on the current subframe and the information about the resources which UE need to use for the uplink data. That means it is mandatory for the UE to decode it successfully if it wants to send some data or receive … SpletPower savings is achieved by configuring the UE (100) with a sparse search space for power savings and a packed search space for normal PDCCH monitoring. The network is aware of the search space being monitored by the UE (100) and can signal the UE (100) to switch between the two search spaces by sending downlink control information (DCI) to …
