Abstract: A wireless communication system may use enhanced feedback indicating a PDSCH decoding outcome. The enhanced feedback may be in an uplink control information (UCI) and carried over PUCCH or PUSCH. The enhanced feedback may be encoded and divided up into two parts of the UCI. A first payload may be carried in a first part of the UCI and a second payload comprising additional feedback information may be carried in a second part of the UCI.

Abstract: Systems and methods for modularized design for inter-physical layer priority uplink control information (UCI) multiplexing are disclosed herein. A user equipment (UE) may determine a first code rate for a first portion of UCI and a second code rate for a second portion of UCI. Different code rates may be used to encode different portions of UCI (e.g., hybrid automatic repeat request acknowledgement (HARQ-ACK) bits, channel state information (CSI) reporting bits, scheduling request (SR) bits, cyclic redundancy check (CRC) bits, etc.). Further, a UE may select a group of bets offset sets based on a physical layer priority type and a UCI multiplexing type.

Abstract: A user equipment (UE) may include one or more processors that are configured to cause UE capability information to be communicated to a radio access network (RAN) node, regarding a maximum number of blind decode attempts (BDAs) supported by the UE. The one or more processors are configured to determine, based on the maximum BDAs, shortened channel control elements (sCCEs) to be used, by the RAN node, to transmit shortened downlink control information (sDCI) via a shortened physical downlink control channel (sPDCCH) and obtain sDCI by monitoring the sPDCCH in accordance with the determined sCCEs.

Abstract: A user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.
