no. 1 approach

[0229] In this embodiment, regarding the above-mentioned FRA scheme 1, a method of separating frequency resources configured and / or indicated by a single DCI and mapping the separated frequency resources to TCI states related to different TRPs is proposed.

[0230] In this embodiment, the method is described by being divided into method 1-1 and method 1-2, but this is only for the convenience of description, and the schemes described in method 1-1 and method 1-2 replace or combine each other and are applicable . As an example, Method 1-2 may be a method of calculating the TB size related to Method 1-1.

[0231] Method 1-1)

[0232] When multiple TCI states are indicated to the UE, frequency resources corresponding to the respective TCI states may be different within a frequency resource region indicated by a single DCI.

[0233] For example, when the precoding granularity is set or indicated to the UE as 2 or 4, frequency resources corresponding to each TCI state may be allo...

no. 2 approach

[0273] In this embodiment, regarding the above-mentioned FRA scheme 2, a method of defining another frequency resource based on the frequency resource configured and / or indicated by a single DCI and mapping to TCI states related to different TRPs is proposed.

[0274] In this embodiment, the method is described by being divided into method 2-1 and method 2-2, but this is only for the convenience of description, and the schemes described in method 2-1 and method 2-2 are substituted or combined with each other and applicable . As an example, Method 2-2 may be a method of calculating the TB size related to Method 2-1.

[0275] Method 2-1)

[0276] It may be considered that the frequency resource allocated to the UE through the frequency resource allocation field in the DCI is mapped to a TCI state related to a specific TRP, and configuration and / or definition are based on the corresponding frequency resource mapping The frequency resource of the TCI state related to another TRP ...

Abstract

Disclosed are a method for transmitting and receiving data in a wireless communication system, and a device for same. Specifically, a method, by which a terminal receives a physical downlink shared channel (PDSCH) in a wireless communication system, includes: a step for receiving setting information related to the PDSCH; a step for receiving downlink control information (DCI) for scheduling the PDSCH; and a step for receiving a first PDSCH and a second PDSCH on the basis of the setting information and the DCI, wherein the DCI includes first transmission configuration indication (TCI)-related information and second TCI-related information.

Description

technical field [0001] The present disclosure relates to a wireless communication system, and more particularly, to a method of determining a transport block size based on a Multiple Input Multiple Output (MIMO) method, a method of transmitting and receiving data, and an apparatus supporting the same. Background technique [0002] Mobile communication systems have been developed to provide voice services while ensuring user mobility. However, in mobile communication systems, not only voice but also data services are expanding. Currently, there is a shortage of resources due to the explosive growth of services, and users demand higher-speed services. As a result, more advanced mobile communication systems are required. [0003] The requirements for next-generation mobile communication systems should be able to support the acceptance of explosive data traffic, a dramatic increase in data rate per user, a significant increase in the number of accepted connected devices, very ...
