Abstract: A user equipment (UE) is connected to a special cell (SpCell) that is configured to schedule the SpCell and a secondary cell (SCell) that is configured to schedule the SpCell. The UE determines a number of blind decodes (BDs) and a number of control channel elements (CCEs) that may be configured for the SpCell and monitors a physical downlink control channel (PDCCH) for downlink control information (DCI) scheduling the SpCell that is transmitted by the SpCell and DCI scheduling the SpCell that is transmitted by the SCell.

Abstract: Systems and methods for beam failure recovery (BFR) are disclosed herein. A user equipment (UE) receives downlink (DL) reference signal(s) on corresponding beam(s) from a base station. The UE performs beam failure detection (BFD) on such beams used for user data to determine whether a beam failure has occurred, and candidate beam detection (CBD) on such beams not used for user data to identify candidate beams for recovering from the beam failure. The BFD and the CBD are based on both uplink (UL) channel performance considerations and DL channel performance considerations, as determined using the DL reference signal(s), such that a beam failure may be determined in the UL, the DL, or both, and a candidate beam may be identified for UL, DL, or both. The UE sends a beam failure recovery request BFRQ with this information to the base station, and the system changes beams accordingly.

Abstract: A user equipment (UE) is provided to select an uplink transmission beam to communicate with a base station in a secondary cell of a carrier aggregation (CA) scheme. The UE can communicate with a first base station in a primary cell (PCell), and receive a command from the wireless network to activate a physical uplink control channel (PUCCH) transmission to a second base station in a secondary cell (SCell). The second base station can be in a being-activated state. The UE can determine whether an uplink spatial relation configuration is provided to the UE, and determine whether the UE supports beam correspondence. Based on the determinations, the UE can select an uplink transmission beam for the PUCCH transmission to the second base station.

Abstract: Some embodiments include an apparatus, method, and computer program product for implementing Channel State information (CSI) feedback for multi-Physical Downlink Shared Channel (PDSCH) transmissions in a wireless communication system. Some embodiments enable a user equipment (UE) to determine Channel Quality Indicators (CQI) and/or Precoding Matrix Indicators (PMI) for multi-PDSCH transmissions that account for effects of a duration of the multi-PDSCH transmission including the maximum interval between the first and last PDSCH transmissions on the CQI and PMI determinations. Some embodiments include a base station that detects a need for a change in a beam direction and adjusts the beam direction accordingly based on the PMI determinations. Some embodiments enable a desired hybrid automatic repeat request (HARQ)-ACK feedback transmission from a single multi-PDSCH transmission. Some embodiments include performing HARQ bundling with an update to the Type 1 HARQ-ACK codebook based on the multi-PDSCH transmission.
