Enhanced reliability for downlink control information (DCI) reception from multiple transmit receive points (M-TRP)

A user equipment (UE) in wireless communication receives a configuration of search space (SS) sets that include a first SS set in a first control resource set (CORESET) and a second SS set in a second CORESET. The first CORESET and the second CORESET have different transmission configuration indicat...

More Information
Summary:A user equipment (UE) in wireless communication receives a configuration of search space (SS) sets that include a first SS set in a first control resource set (CORESET) and a second SS set in a second CORESET. The first CORESET and the second CORESET have different transmission configuration indication (TCI) states. The UE repeatedly receives downlink control information (DCI) via a first physical downlink control channel (PDCCH) and a second PDCCH. The first PDCCH is allocated with a first set of time-and-frequency resources configured for first SS set and the second PDCCH is allocated with a second set of time-and-frequency resources configured for the second SS set. The UE then parses the DCI to obtain control information for the wireless communication. Alternatively, the configuration of SS sets received by the UE is in one CORESET that has at least a TCI state and a second TCI state activated.
