SpletA method is provided for detection of an uplink grant for a user agent (UA). The method comprises detecting a semi-persistent scheduling (SPS) activation/reconfiguration signaling over a physical downlink control channel (PDCCH) only during an SPS activation window, wherein the SPS activation window precedes a discontinuous reception (DRX) … SpletUE receives the PDCCH order and triggers a Contention Free RACH. PDCCH order can only be sent via DCI Format 0_1; PDCCH order is scrambled with CRNTI and is sent in Dedicated SearchSpace/CORESET for DCI Format 0_1. UE receives the following information from UE. RACH preamble; SSB index; RACH Occasion; RACH Applicable to both SA and NSA mode.
Splet26. maj 2024 · The basic unit of PDCCH is a Control Channel Element (CCE). A group of 6 REGs make one CCE. A PDCCH consists of 1, 2, 4, 6, 8, or 16 CCEs. This is defined based on Aggregation Level (AL). There is one-to-one relation between AL and the number of CCEs, i.e. AL=1 means 1 CCE, AL=4 means 4 CCEs etc. Downlink Control. 5g Network.
