Abstract

The device determines a first resource block (RB) for uplink channel transmission with frequency hopping applied at a specific time resource, and transmits the uplink channel through consecutive resource blocks in the frequency domain from the first RB, wherein the first RB is determined differently depending on whether the specific time resource is a half-duplex resource or a full-duplex resource, and when the specific time resource is a full-duplex resource, the first RB is determined based on a first parameter indicating the lowest resource block among resource blocks that overlap between a first frequency resource constituting an uplink band portion and a second frequency resource constituting an uplink subband, and a second parameter indicating the size of the overlapping resource blocks.

Description

Method of operation of a device in a wireless communication system and a device using said method Method of operation of a device in a wireless communication system and a device using said method The present disclosure relates to a method of operation of a device in a wireless communication system and a device utilizing said method. As more communication devices require larger communication capacities, the need for enhanced mobile broadband communication compared to existing radio access technology (RAT) is emerging. Furthermore, Massive Machine Type Communications (MTC), which connects multiple devices and objects to provide various services anytime and anywhere, is also one of the major issues to be considered in next-generation communication. In addition, communication system designs that take into account services and terminals sensitive to reliability and latency are being discussed. Thus, the introduction of next-generation radio access technologies that consider enhanced mobile broadband communication, massive MTC, and Ultra-Reliable and Low Latency Communication (URLC) is being discussed, and for convenience, this technology is referred to as new RAT or NR in this disclosure. In NR, full duplex (FD) operation can be performed. When performing FD operation, downlink reception and uplink transmission can be performed simultaneously within a specific time resource, which differs from half duplex (HD) operation, where only one of downlink reception or uplink transmission can be performed within a specific time resource. For FD operation, i) some frequency resources within the same time resource may be allocated as a downlink subband and other frequency resources as an uplink subband, or ii) frequency resources that can be used for both downlink reception and uplink transmission within the same time resource may be allocated. The former can be referred to as a subband-wise full duplex (hereinafter referred to as subband full duplex or SBFD), and the latter can be referred to as a spectrum-sharing full duplex (hereinafter referred to as SSFD). In a time resource operating as an SBFD (let's call this an SBFD time resource), the terminal can perform transmission of an uplink channel (e.g., PUSCH (physical uplink shared channel) or PUCCH (physical uplink control channel)) using resources within the uplink subband. In the configuration of repetitive transmissions of an uplink channel, the frequency resources for said repetitive transmissions were configured in the prior art on the premise that only HD time resources exist. On the other hand, in future wireless communication systems, each repetition may be performed in SBFD time resources or HD time resources (non-SBFD time resources). In such cases, in SBFD time resources, the frequency resources allocated for transmission of the uplink channel may overlap with frequency resources that are not uplink subbands.
