Abstract: Some embodiments include an apparatus, method, and computer program product for enhanced Hybrid Automatic Repeat Request (HARQ)-ACK in a fifth generation (5G) wireless communications system. A user equipment (UE) can receive, during a HARQ-ACK window, a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission corresponding to a SPS PDSCH release. The UE can generate a Hybrid Automatic Repeat Request (HARQ)-ACK information bit corresponding to the reception. The UE can be configured with an offset value, k, and a length, l, of the HARQ-ACK window associated with an uplink transmission slot n, of a Physical Uplink Control Channel (PUCCH) transmission, and determine a starting slot of the HARQ-ACK window as n−k. When a corresponding valid uplink transmission slot is not available, the UE can transmit the HARQ-ACK information bit in the uplink transmission slot n of the PUCCH transmission.

Abstract: Systems and methods for associating phase tracking reference signal (PTRS) and demodulation reference signal (DMRS) ports for multi-beam physical uplink shared channel (PUSCH) transmissions are described herein. A base station may provide, to a user equipment (UE), PTRS and DMRS port associations for the multiple beams on which the PUSCH is transmitted. In some cases, a 2-bit downlink control information (DCI) field may be used to alternatively provide single beam or multiple beam PTRS and DMRS port associations to a UE. For non-codebook (NCB) based transmissions, the UE may alternatively determine PTRS and DMRS port associations for multiple beams independently of any PTRS and DMRS port association indicated in DCI.

Abstract: The present disclosure relates to DMRS overhead adaptation with AI-based channel estimation. A wireless device may be configured to receive, from a network device, a downlink data transmitted using a DMRS pattern; perform an AI-based downlink channel estimation based on the downlink data, including: inputting one or more received downlink DMRS symbols included in the received downlink data to a neural network model for downlink channel estimation stored in the memory of the wireless device, to obtain, as outputs of the neural network model, an estimated downlink channel corresponding to the downlink data and an optimal downlink DMRS pattern for the estimated downlink channel; and report the optimal downlink DMRS pattern to the network device.

Abstract: The present disclosure is directed to AP-SRS triggering offset enhancement for further enhanced MIMO. User equipment (UE), base stations, apparatus, methods, computer-readable memory media, and computer program products are disclosed. The UE may be configured to receive an offset information associated with AP-SRS transmission of the UE; determine a slot offset associated with the AP-SRS transmission, at least based on the offset information; determine a specific slot for the AP-SRS transmission, based on the determined slot offset; and perform the AP-SRS transmission in the determined specific slot.

Abstract: Systems and methods disclosed herein relate to acknowledgement signaling sent by a user equipment (UE) in response to downlink control information (DCI) received from a base station that schedules the use of multiple physical uplink control channels (multi-PUSCH) or multiple physical downlink control channels (multi-PDSCH). Acknowledgement signaling may inform the base station that DCI scheduling the multi-PUSCH/multi-PDSCH was received (or not), so that the base station may reclaim those scheduled resources in the case that the UE remains unaware of them. Methods for performing this signaling include, e.g., the use of HARQ-ACK codebooks (whether in a semi-static or dynamic manner), and aperiodic sounding reference signals (A-SRS). Embodiments involving such DCI received across multiple component carriers of different serving cells of the UE are contemplated. Acknowledgment signaling according to multi-PUSCH/multi-PDSCH subgroups, monitoring windows, acknowledgment signaling enablement/disablement, and the use of DCI to trigger acknowledgment signaling are also discussed.

Abstract: A user equipment (UE) may receive a measurement reporting capability request from a base station and further transmit, in response to the request, an indication of the UE's measurement reporting capability. The UE may further receive, signaling comprising a channel status information (CSI) request trigger from the base station. In response to receiving the CSI request trigger, the UE may transmit a measurement report to the base station, wherein the measurement report may comprise at least one received signal strength indicator (RSSI) measurement.
