PDSCH Reception Symbol Indication for Multi-Slot SBFD Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication scenarios where a network device sends a Physical Downlink Shared Channel (PDSCH) in multiple slots, there is a discrepancy between the terminal and the network device regarding which symbols can be used for reception, leading to inconsistent understanding and potential communication quality issues.
Innovation Solution
A method and apparatus for a terminal to determine symbols for receiving PDSCH transmission in multiple slots based on first information from a network device, distinguishing between Subband Full Duplex (SBFD) and non-SBFD symbols, ensuring alignment with the network's understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network device sends PDSCH in multiple slots without explicit symbol indication, then the transmission flexibility is improved, but the understanding consistency between terminal and network device deteriorates
Solution Approach 1:
The network device performs preliminary action by sending indication information in advance to tell the terminal which symbols can be used for PDSCH reception. This preliminary notification ensures that both the network device and terminal have consistent understanding before the actual multi-slot PDSCH transmission begins, resolving the contradiction between transmission flexibility and understanding consistency.
2Device complexity
If the terminal determines symbol usage without network device indication, then the device complexity is reduced, but the communication quality deteriorates
Solution Approach 1:
The indication information mechanism acts as a feedback loop where the network device communicates its symbol usage intentions to the terminal. This feedback ensures that the terminal's simple determination process aligns with the network device's transmission plan, maintaining communication quality without increasing terminal complexity.

AI summary
The present disclosure relates to the technical field of communications, and specifically relates to a reception determination method and apparatus, a reception indication method and apparatus, a communication apparatus, and a storage medium. The reception determination method comprises: according to first information sent by a network device, determining a symbol that can be used for receiving a physical downlink shared channel (PDSCH) transmitted in a plurality of slots, wherein the symbol comprises at least one of a sub-band full-duplex (SBFD) symbol and a non-SBFD symbol. In the present disclosure, a terminal can determine, according to first information, a symbol that can be used for receiving a PDSCH transmitted in a plurality of slots. On this basis, it can be ensured that the symbol which is determined by the terminal and can be used for receiving the PDSCH transmitted in the plurality of slots is consistent with the understanding of a network device, which is conductive to ensuring the communication quality between the network device and the terminal.
