Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently determining and transmitting resources for data and control information via uplink shared channels, particularly in 5G networks, due to resource shortages and high-speed service demands.
Innovation Solution
A method for a user equipment (UE) to receive configuration information for allocating resources on a physical uplink shared channel (PUSCH), map transport blocks to multiple slots, and multiplex uplink control information (UCI) with PUSCH, determining modulation symbols based on the scaled size or resource of the TB across slots, and using a predetermined redundancy version sequence for repetitive transmission.

1Productivity
If dynamic TDD is used to vary the number of OFDM symbols in uplink and downlink according to data traffic directions, then spectral efficiency is improved, but resource allocation complexity increases
Solution Approach 1:
The patent implements dynamic TDD by allowing the base station to flexibly adjust the number of OFDM symbols allocated to uplink and downlink within a slot based on real-time data traffic conditions. This dynamic reconfiguration enables the system to adapt resource allocation to varying traffic demands, improving spectral efficiency while managing complexity through standardized adjustment mechanisms.
2Length of stationary object
If beamforming and massive MIMO technologies are used to alleviate path loss in mmWave band, then transmission distance is improved, but device complexity increases
Solution Approach 1:
The patent combines beamforming and massive MIMO technologies to address path loss in the mmWave band. By merging these techniques, the system achieves extended transmission distance through coordinated spatial processing and antenna array utilization, while managing complexity through integrated implementation approaches.
Solution Approach 2:
The patent employs universal resource allocation mechanisms that work across different transmission scenarios including beamforming and massive MIMO. The resource allocation method is designed to be multi-functional, supporting various antenna configurations and beamforming strategies without requiring separate allocation procedures for each technology.
3Adaptability or versatility
If configuration information is provided for each slot to enable flexible resource allocation, then adaptability is improved, but signaling overhead increases
Solution Approach 1:
The patent segments resource allocation configuration into slot-level and transport block-level parameters. By dividing the configuration information, the system provides flexible slot-specific resource allocation while reducing overall signaling overhead through hierarchical structuring and selective configuration application.
Solution Approach 2:
The patent utilizes parameter changes to enable flexible resource allocation without excessive signaling. By configuring parameters at appropriate granularity levels and allowing dynamic adjustment of allocation parameters based on traffic conditions, the system achieves adaptability while controlling signaling overhead through efficient parameter management.

AI summary
Disclosed is a method by which a terminal transmits a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The terminal can receive, from the base station, configuration information for allocating a resource for transmitting a transport block (TB) through the PUSCH, and map the TB to a plurality of slots constituting the resource on the basis of the configuration information. Thereafter, the terminal can transmit the TB on the plurality of slots through the PUSCH.
