Provided are a method and apparatus for multiplexing UE-initiated beam reporting (UEIBR) and hybrid automatic repeat request (HARQ) feedback using a physical uplink control channel (PUCCH) in a wireless communication system. A terminal identifies whether transmission of first uplink control information related to UEIBR is required, and identifies whether transmission of second uplink control information including HARQ feedback is required. Furthermore, the terminal multiplexes and transmits the first uplink control information and the second uplink control information on a single PUCCH resource, wherein the multiplexing is performed on the single PUCCH resource configured according to the same PUCCH format.

Provided are a method and apparatus for processing UE-initiated beam reporting (UEIBR) and hybrid automatic repeat request (HARQ) feedback using a physical uplink control channel (PUCCH) in a wireless communication system. A terminal identifies whether transmission of first uplink control information related to UEIBR is required on a first PUCCH resource and identifies whether transmission of second uplink control information including HARQ feedback is required on a second PUCCH resource. Furthermore, when the first PUCCH resource and the second PUCCH resource are respectively configured according to different PUCCH formats, the terminal transmits only the second uplink control information.

Provided are a method and apparatus for processing user equipment-initiated beam reporting (UEIBR) and a scheduling request (SR) using a physical uplink control channel (PUCCH) in a wireless communication system. A terminal identifies whether transmission of first uplink control information related to UEIBR is required on a first PUCCH resource, and identifies whether transmission of second uplink control information for an SR is required on a second PUCCH resource. Furthermore, the terminal drops the transmission of the second uplink control information when the first PUCCH resource and the second PUCCH resource overlap.

Provided are a method and device for processing ambient Internet of Things (IoT) data in a wireless communication system. The device receives a paging message including first device identification information, and checks whether the first device identification information matches second device identification information stored in the device. Further, based on a result of the checking, the device transmits a medium access control (MAC) message including upper layer data, wherein the paging message includes a first security parameter and information indicating presence of the first security parameter.

Provided are a method and device for ambient IoT communication in a wireless communication system. The device receives a paging message including first ambient internet of things (AIoT) device identification information, and forwards the first AIoT device identification information included in the paging message to an upper layer. Further, the device receives, from the upper layer, an indication regarding whether the first AIoT device identification information matches. The paging message includes a predetermined field, and based on the predetermined field, the first AIoT device identification information may be forwarded to the upper layer.

Provided are a method and device for processing a medium access control (MAC) message in a wireless communication system. The device receives a first MAC message for paging, and after receiving the first MAC message, transmits a second MAC message including device to reader (D2R) upper layer data. Further, after transmitting the second MAC message, the device receives a third MAC message including reader to device (R2D) upper layer data. Here, the first MAC message includes device identification information and information indicating presence of the device identification information, and the third MAC message includes information indicating presence of the R2D upper layer data.

Provided are a method of a base station for controlling transmission and reception of data through a network slice. The method includes: receiving network slice request information from a terminal in which a network slice is configured; controlling so as to deliver the network slice request information to a core network entity; and receiving, from the core network entity, specific network slice information configured on the basis of the network slice request information.

Provided is a method for performing a random access procedure by an Ambient IoT terminal. The method may include: receiving random access type indication information from a reader device; determining a random access type based on the random access type indication information; and starting the random access procedure according to the random access type.

Provided are a method and apparatus for receiving notification information in a wireless communication system. The terminal may receive a Narrowband-Internet of Things (NB-IoT) system information block type1. Then, after receiving the NB-IoT system information block type1, the terminal may receive at least one specific NB-IoT system information block type including Earthquake and Tsunami Warning System (ETWS) notification information. Subsequently, the terminal may forward at least a part of the ETWS notification information to an upper layer, wherein the ETWS notification information may include warning area coordinates information.
