One aspect of the present invention discloses a terminal of a wireless communication system. The terminal comprises a communication module and a processor for controlling the communication module, wherein the processor generates a hybrid automatic repeat request (HARQ)-ACK codebook including one or more bits indicating whether reception of a channel or signal is successful, and transmits the HARQ-ACK codebook to a base station of the wireless communication system, wherein the HARQ-ACK codebook is generated on the basis of a slot corresponding to a value of an HARQ-ACK feedback timing parameter (K1) set in a sub-slot level, and each of bits configuring the HARQ-ACK codebook corresponds to at least one sub-slot form among a plurality of sub-slots included in the slot.

A wireless communication method and a terminal device, the method including the following. A terminal device receives a media access control (MAC) control element (CE) transmitted from a network device, where the MAC CE indicates a first downlink configuration. The terminal device determines an effective time of the first downlink configuration and/or an effective time of the MAC CE according to a signal transmission RTT between the terminal device and the network device.

Presented are systems and methods for parameter estimation. A wireless communication device may determine that a first number of PDCCH transmissions, scheduled from a wireless communication node, that are associated and are PDCCH candidates for blind detection decoding, is K, wherein K is an integer larger than 1. The wireless communication device may determine a second number of PDCCH candidates to be counted for monitoring. The wireless communication device may count the second number of PDCCH candidates for monitoring with respect to the first number of PDCCH transmissions.

A terminal according to one aspect of the present disclosure includes: a receiving section that receives one Downlink Control Information (DCI) for scheduling two Physical Downlink Shared Channels (PDSCHs); and a control section that determines one or two Quasi Co-Locations (QCL) parameters for the two PDSCHs based on whether or not presence of a Transmission Configuration Indication (TCI) field is configured. According to one aspect of the present disclosure, it is possible to appropriately determine QCL parameters for multiple panels/TRPs.

A terminal according to one aspect of the present disclosure includes: a control section that derives a Quasi-Co-Location (QCL) assumption of an Aperiodic Channel State Information-Reference Signal (A-CSI-RS) based on a specific Transmission Configuration Indication state (TCI state) for a Physical Downlink Shared Channel (PDSCH) in a case where both of following conditions (1) and (2) are satisfied, where (1) a scheduling offset between reception of a downlink control channel for conveying downlink control information for scheduling the A-CSI-RS, and reception of the A-CSI-RS is less than a reported value of a duration for beam switch, and (2) there is not another downlink signal that includes an instructed TCI state or there is another downlink signal that does not include the instructed TCI state in a same symbol as a symbol of the A-CSI-RS; and a receiving section that receives the A-CSI-RS based on the QCL assumption.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, downlink control information (DCI) that includes a semi-persistent scheduling (SPS) activation indication.
