Abstract: Wireless communication systems can include multiple Transmission and Reception Points (TRPs). Systems, devices, and techniques for control signaling of Precoding Resource block Group (PRG) size configuration for multi-TRP operations are described. A described technique includes determining, by a User Equipment (UE), a PRG size based on a downlink control information (DCI) message that provides scheduling information for a physical ?downlink shared channel (PDSCH); receiving, by the UE, a group of PDSCH transmissions from multiple TRPs that are transmitted in accordance with the DCI message; and decoding, by the UE, one or more of the PDSCH transmissions based on the PRG size.

Abstract: Systems, devices, and techniques for wireless communications are described. A described technique includes receiving, by a user equipment (UE) from one or more Transmission and Reception Points (TRPs), a physical downlink shared channel (PDSCH) transmission; determining, by the UE for a physical uplink control channel (PUCCH) carrying hybrid automatic repeat request-acknowledgement (HARQ-ACK), a TRP index in accordance with a control resource set (CORESET) scheduling the PDSCH transmission; and transmitting, by the UE via the PUCCH, HARQ-ACK information based on the receiving of the PDSCH transmission in accordance with the TRP index.

Abstract: A method is provided to generate and control transmission of reference symbols in a synchronization subframe, wherein a reference symbol includes reference values mapped to a block of K subcarriers. The method includes generating data corresponding to a basic subsequence of K−R1−R2 reference values, where R1 and R2 are integers such that 1≤R1+R2

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for selecting a TCI-State for receiving downlink transmissions. In one example a processor/UE is configured to determine one or more candidate TCIs for a downlink slot; determine a scheduling offset between a physical downlink shared channel (PDSCH) and a physical downlink control channel (PDCCH); prioritize the candidate TCIs based on the scheduling offset; identify a highest priority candidate TCI; and select the highest priority candidate TCI for receiving the PDSCH.
