Abstract: A user equipment (UE), or other network component can operate to configure different sets of resources for an uplink (UL) physical channel for an uplink (UL)-to-downlink (DL) channel occupancy time (COT) sharing to coexist with another radio access technology (RAT). An energy detection (ED) threshold can be selected from the different sets of resource configurations for an UL transmission based on one or more conditions. A gap can be configured between a physical random access control channel (PRACH) transmission and a PUSCH transmission based on one of at least a first value associated with a numerology between the PRACH and the PUSCH and a second value greater than the first value. The UL transmission can be provided based on the ED threshold or the configured conditional gap via the UL physical channel.

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: Methods and devices for a base station acting as a primary cell to perform dual spectrum sharing (DSS) with a first user equipment device (UE) over a 5G NR connection and a second UE over an LTE connection. The first UE establishes the 5G NR connection with the primary cell and one or more secondary cells. One of the secondary cells is configured in the 5G NR connection to provide downlink control information to the UE for the primary cell, to avoid collisions by the primary cell with LTE control transmissions.

Abstract: Various user equipment (UE) operations performed when the UE is in multiple Downlink Control Information (multi-DCI) based multiple transmission and reception point (multi-TRP) configuration. The operations receiving, from one of the first or second gNBs, one or more cell reference signal (CRS) rate matching patterns, wherein the one or more CRS rate matching patterns comprise an indication of a control resource set (CORESET) pool for each of the one or more CRS rate matching patterns and applying the one or more CRS rate matching patterns to a CORESET for a Physical Downlink Shared Channel (PDSCH) based on the indication of the CORESET pool.

Abstract: Methods, systems, and devices for wireless communications are described. To monitor a PDCCH for CA, a UE may receive PDCCH candidates in a plurality of configured component carriers (CCs). In response to a determination that a maximum number of virtual CCs that the UE is capable of monitoring for PDCCH is smaller than a number of the plurality of configured CCs, the UE groups the plurality of configured CCs into CC groups based at least in part on SCS numerologies and PDCCH monitoring configurations corresponding to span patterns within a slot of a DL subframe. The UE determines a maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups. The UE then monitors at least a first portion of the PDCCH candidates based on the maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups.

Abstract: A method for Resource Allocation for Msg-3 Transmission on an unlicensed spectrum may include receiving a random access response (RAR) grant comprising a 12-bit frequency domain resource allocation (FDRA) field. If the resource allocation type is type-1 some embodiments may zero padding the FDRA field to interpreting the 12-bit FDRA and determine a starting position of allocated resources where a Scheduled PUSCH Transmission is transmitted in an unlicensed spectrum. Some embodiments may use a virtual Bandwidth Part (BWP) to obtain a starting position and a length of allocated resources.

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.
