PUSCH Symbol Indication for Multi-Slot SBFD Uplink Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inconsistent understanding between network devices and terminals regarding the availability of symbols for transmitting physical uplink shared channels (PUSCH) in multiple slots leads to communication quality issues.
Innovation Solution
A method and apparatus for determining and indicating symbols available for transmitting PUSCH in multiple slots, including subband full-duplex (SBFD) and non-SBFD symbols, based on information received from a network device, ensuring alignment between terminal and network device understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network device sends PUSCH in multiple slots without explicit symbol availability indication, then the transmission flexibility is improved, but the communication quality deteriorates due to inconsistent understanding between terminal and network device
Solution Approach 1:
The network device performs preliminary action by sending indication information in advance to specify which symbols are available for PUSCH transmission in multiple slots. This allows the terminal to know beforehand which symbols can be used, eliminating inconsistent understanding and ensuring reliable communication while maintaining transmission flexibility.
2Reliability
If the network device provides detailed symbol availability information for PUSCH transmission, then the communication quality is improved, but the signaling overhead increases
Solution Approach 1:
The indication information provides local quality by specifying symbol availability on a per-symbol basis within the multiple slots. Instead of providing uniform information for all symbols, the network device selectively indicates which specific symbols are available, reducing unnecessary signaling while ensuring accurate communication quality where needed.

AI summary
The present disclosure relates to the technical field of communications, and in particular to a sending determination, sending indication method and apparatus, a communication apparatus, and a storage medium. A sending determination method comprises: according to first information sent by a network device, determining a symbol capable of being used for sending a physical uplink shared channel (PUSCH) transmitted in a plurality of slots, wherein the symbol comprises at least one of the following: a sub-band full duplex (SBFD) symbol and a non-SBFD symbol. According to the present disclosure, a terminal can determine, according to the first information, the symbol capable of being used for sending the PUSCH transmitted in the plurality of slots. Therefore, it can be ensured that the symbol determined by the terminal and capable of being used for sending the PUSCH transmitted in the plurality of slots is consistent with the understanding of the network device, thereby ensuing the communication quality between the network device and the terminal.
