Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for a single downlink control information (DCI) signal that supports multi-transmission reception point (TRP) transmissions from different TRPs (e.g., different 5G Node Bs or different antenna panels.) A user equipment (UE) receives a single DCI signal that includes a first transmission configuration indicator (TCI) state of a first TRP, a second TCI state of a second TRP, and a demodulation reference signal (DMRS) port indication value. The UE uses the DMRS port indication value to determine a first DMRS port and a first code division multiplexing (CDM) group of the first TCI state and a second DMRS port and a second CDM group of the second TCI state. The UE receives a multi-Physical Downlink Shared Channel (PDSCH) signal that includes multi-TRP transmissions, and uses the above determinations to decode data from the first and/or the second TCI states.

Abstract: Systems and methods of beam reporting for multiple DL processes are described. A UE receives a beam management processes configuration that provides information about beam management reference signals for beam management procedures. The UE transmits a UE capability report that indicates beam management capabilities of the UE and, later, an indication of whether the UE intends to engage in beam refinement. The UE measures the beam management reference signals and receives a beam reporting message that indicates at least one of the beam management procedures to report. In response, the UE transmits the beam report. The beam report contains beam management reference signal measurements of the beam management procedures indicated by the beam reporting message.

Abstract: Technology for a user equipment (UE) to perform reduced transmission time interval (TTI) data transmission within a wireless communication network is disclosed. The UE can process a process, for transmission to an eNodeB, control information within a short transmission time interval (TTI) over a short TTI resource block (RB) set within a short physical uplink control channel (S-PUCCH), wherein the short TTI is shorter in time than a TTI that has a duration of at least one (1) millisecond, and wherein the S-PUCCH is a subset of resources available for a short physical uplink shared channel (S-PUSCH) and the S-PUSCH is a subset of resources available for a legacy PUSCH transmission; and process, for transmission to the eNodeB, data within the short TTI over the short TTI RB set within the S-PUSCH.
