    Abstract: Systems and techniques for transmitting channel state information (CSI) include: receiving configuration information related to the CSI from a base station, the configuration information including information on a CSI-RS resource set; receiving a CSI-reference signal (CSI-RS) from the base station; and transmitting the CSI to the base station based on the configuration information and the CSI-RS. The CSI-RS resource set includes M CSI-RS resource groups; in addition, N CSI-RS resource groups (NMI) for reporting the CSI are determined from the M CSI-RS resource groups; the CSI includes N CSI sets generated based on a CSI-RS resource combination in the N CSI-RS resource groups. To generate an n-th (1≤n≤N) CSI set, a specific CSI-RS resource in an n-th (1≤n≤N) CSI-RS resource group is used for channel measurement; and a specific CSI-RS resource in the remaining CSI-RS groups other than the n-th CSI-RS resource group is used for interference measurement.

    Abstract: Disclosed herein are a method and a device for transmitting a message in an initial access procedure by a user equipment (UE) in a wireless communication system. According to the present disclosure, a UE may transmit to a base station capability information associated with transmission power of the UE and the information may include a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive first control information for transmitting a message associated with an initial access and the control information may include a TPMI used for the UE to transmit the message. Thereafter, the UE may transmit to the base station the message by using transmission power determined based on the TPMI and the transmission power may be determined according to whether the TPMI is included in the at least one TPMI.

    Abstract: In the present specification, settings for a link direction and link availability of a time resource for a DU child link may be referred to as DU setting. The resource types from an IAB node DU perspective are UL, DL, and F, and the settings for availability may be classified into NA, hard resources, and soft resources, respectively. Specifically, the IAB node may receive resource setting information, wherein the resource setting information may include link direction information and availability information. The link direction information may indicate whether the type of a specific resource is UL, DL, or F, and the availability information may indicate whether a specific resource is a hard resource, an NA resource, or a soft resource. Considering the feature of sharing resources in a TDM scheme between a MT and a DU in the IAB node, the present specification proposes a feature to be had by a slot format setting for the IAB node.

The CSI-RS resource set includes M CSI-RS resource groups; in addition, N CSI-RS resource groups (N≤M) for reporting the CSI are determined from the M CSI-RS resource groups; the CSI includes N CSI sets generated based on a CSI-RS resource combination in the N CSI-RS resource groups. To generate an n-th (1≤n≤N) CSI set, a specific CSI-RS resource in an n-th (1≤n≤N) CSI-RS resource group is used for channel measurement; and a specific CSI-RS resource in the remaining CSI-RS groups other than the n-th CSI-RS resource group is used for interference measurement.

    Abstract: The disclosure discloses a method for reporting channel state information (CSI) in a wireless communication system, and an apparatus therefor. Particularly, a method by which a user equipment (UE) reports channel state information (CSI) in a wireless communication system comprises the steps of: receiving, from a base station (BS), CSI-related configuration information; receiving, from the base station, a reference signal; calculating CSI on the basis of the reference signal; and transmitting the CSI to the base station, wherein the CSI includes information related to a codebook, the information related to the codebook includes a bitmap related to an amplitude coefficient and a phase coefficient, and the size of the bitmap may be set by multiplying the number of bases of a spatial domain for the CSI by the number of bases of a frequency domain for the CSI.
