Title:
METHOD AND APPARATUS FOR TRANSMITTING AN UPLINK SIGNAL IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/020832
Kind Code:
A1
Abstract:
The present disclosure provides a transmission method of an uplink signal and a user equipment thereof. The transmission method includes: transmitting a first message comprising a PRACH (Physical Random Access Channel) preamble and data part; receiving a fallback random access response comprising configuration information associated with a transport block size for transmitting a PUSCH (Physical Uplink Shared Channel); determining the transport block size for transmitting the PUSCH by comparing the received configuration information associated with the transport block size with a transport block size of the first message; and transmitting the PUSCH comprising the data part based on the determined the transport block size for transmitting a PUSCH.
