Disclosed are a communication technique which merges, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security- and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. A method for a terminal of a communication system may comprise the steps of: receiving, from a base station, information indicating LBRM; identifying a parameter related to the maximum number of layers for one transport block; identifying the maximum number of layers for the one transport block on the basis of the parameter; identifying a transport block size to which the LBRM is applied, on the basis of the determined maximum number of layers; and transmitting or receiving data to or from the base station on the basis of the transport block size.

Apparatus and methods of resource mapping for enhanced PDCCH transmission with multiple beams from multiple TRPs are disclosed. The apparatus includes: a processor that determines transmission resources capable of transmitting Physical Downlink Control Channel (PDCCH) using a Control Resource Set (CORESET) by a plurality of wireless transmitting-receiving identities including a first identity and a second identity; and determines a resource candidate from the transmission resources for transmitting the PDCCH; where the resource candidate includes a first resource group having a first set of Resource Elements (REs) for transmission by the first identity, and a second resource group having a second set of REs for transmission by the second identity; and a transmitter that transmits the PDCCH using the resource candidate.

This application provide a resource indication method and a related device. According to the method provided in this application, a terminal device can send a HARQ-ACK on a PUCCH resource in at least one sub-slot. The resource indication method may be applied to the terminal device. The method may include: The terminal device may receive DCI from a network device, where the DCI indicates a slot used by the terminal device to transmit a HARQ-ACK. After receiving the DCI, the terminal device may send the HARQ-ACK on a PUCCH resource in at least one sub-slot of the slot indicated by the DCI. The slot includes at least two sub-slots. In other words, the terminal device may send the HARQ-ACK on a PUCCH resource in one sub-slot of the slot, or may send the HARQ-ACK on a PUCCH resource in a plurality of sub-slots of the slot.

A terminal apparatus transmits a PUCCH in a certain slot, and receives multiple DCI formats on a set of PDCCH monitoring occasions corresponding to the certain slot. In a case that multiple PUCCHs exist in the certain slot and that the multiple PUCCHs include a first PUCCH including a first type HARQ-ACK codebook and a second PUCCH including a second type HARQ-ACK codebook, the second PUCCH is not transmitted.

A terminal including: a reception unit configured to receive feedback information for uplink transmission based on a configured grant from a base station apparatus; a control unit configured to determine an application target of a transmission power control command included in the feedback information; and a transmission unit configured to apply the transmission power control command to uplink transmission of the application target.

A terminal includes a control unit configured to determine, in a case where a first transmission of transmitting an HARQ (Hybrid Automatic Repeat Request) response received from another terminal to a base station overlaps in at least in a time domain with a second transmission to a base station, at least one of a priority and a priority order, of each transmission, and to determine control associated with the first transmission and the second transmission, based on the priorities, and a transmission unit configured to perform the control associated with the first transmission and the second transmission, based on the determination, and the control unit changes control associated with determination of priority order of transmissions, based on a configuration associated with communication.

Disclosed are an information sending method, information receiving method, apparatus, and device. The information sending method includes: receiving a physical sidelink feedback channel (PSFCH); determining a first duration; and sending a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) not earlier than a first moment, where the first moment is a moment the first duration after an end moment of receiving the PSFCH. A terminal device does not send the PUCCH or the PUSCH before the moment the first duration after the end moment of receiving the PSFCH. Because the terminal device can determine the first duration, it is ensured that the terminal device may have sufficient time to process the PUCCH or the PUSCH. The PUCCH or the PUSCH may be used to carry sidelink hybrid automatic repeat request (HARQ) information, and the HARQ information may be generated based on the received PSFCH.
