Abstract: Various embodiments herein provide techniques for a unified transmission configuration indicator (TCI) framework for multi-transmission-reception point (TRP) operation in a wireless cellular network. For example, embodiments may relate to use of a joint TCI codepoint to indicate one or more TCI states (e.g., a joint uplink (UL)/downlink (DL) TCI state, a UL TCI state, and/or a DL TCI state). The techniques may be used for multi-downlink control information (DCI) multi-TRP operation and/or single-DCI multi-TRP operation. Embodiments further relate to techniques for transmission repetition and uplink power control. Other embodiments may be described and claimed.

Abstract: A user equipment (UE) can include processing circuitry configured to decode control information of a physical down-link control channel (PDCCH) received via a resource within a control resource set (CORESET) occupying a subset of a plurality of OFDM symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCH. The DM-RS can be detected within the slot, the DM-RS starting at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS.

Abstract: Systems and methods for transmission of full power uplink transmission in 5G networks are described. The gNB provides TPMI precoding information in DCI of a PDCCH in which the field size for precoding information and number of layers are fixed irrespective of the SRI. The gNB indicates in RRC signaling the use of codebook-based transmission for UL. If different SRS resources with different number of antenna ports are configured, the bitwidth of the SRI field is the maximum number of ports among the configured SRS resources in an SRS resource set with usage set to ‘codebook’. If the number of ports for a configured SRS resource in the set is less than the maximum number of ports, the most significant bits of the field have a value of ‘0’. The bitwidth is dependent on UE coherence capabilities and a maxrank of the UE.
