Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single PRG size configuration is used for both SBFD and non-SBFD time domain units, then device complexity is reduced, but communication performance and transmission accuracy deteriorate
Solution Approach 1:
The patent segments the PRG configuration into two distinct parts: one for SBFD time domain units and another for non-SBFD time domain units. This allows each segment to be optimized independently for its specific operational context, with the network device providing separate indication information for PRG sizes in SBFD and non-SBFD scenarios, thereby improving transmission accuracy without excessively increasing device complexity through structured configuration management.
Solution Approach 2:
The patent implements dynamic PRG size selection based on the duplex operation mode. The network device dynamically indicates appropriate PRG sizes through signaling (RRC or DCI) according to whether the current time domain unit is SBFD or non-SBFD, allowing the system to adapt to changing operational conditions and optimize transmission accuracy for each scenario rather than using a static single configuration.
2Manufacturing precision
If separate PRG size configurations are provided for SBFD and non-SBFD time domain units, then transmission accuracy is improved, but signaling overhead and device complexity increase
Solution Approach 1:
The patent creates a universal PRG configuration framework that handles both SBFD and non-SBFD scenarios through a unified indication mechanism. The network device uses a single signaling structure (supporting both RRC and DCI formats) that can convey PRG size information applicable to different time domain unit types, allowing the system to maintain transmission accuracy for both modes while avoiding the need for entirely separate configuration systems.
Solution Approach 2:
The patent enables the system to self-adapt to different operational modes through automated PRG size determination. The UE automatically selects the appropriate PRG size based on the indicated configuration and the current duplex operation mode (SBFD or non-SBFD), eliminating the need for manual configuration management and reducing the burden on network operators while maintaining high transmission accuracy.
3Productivity
If PRG size is dynamically adjusted based on SBFD operations, then communication efficiency is improved, but processing complexity increases
Solution Approach 1:
The patent applies preliminary action by having the network device pre-indicate the appropriate PRG size through RRC signaling or DCI before the actual data transmission occurs. This allows the UE to have the configuration information ready in advance, enabling efficient transmission without real-time calculation or complex processing during the actual communication, thus improving communication efficiency while keeping processing complexity manageable through advance preparation.

AI summary
The present disclosure provides a communication processing method and apparatus and a readable storage medium. The method comprises: receiving first signaling sent by a network device, the first signaling comprising pre-coding resource block group (PRG) configuration information applicable to a sub-band full-duplex (SBFD) time domain unit; and determining a first PRG size for downlink (DL) transmission in the SBFD time domain unit according to the first signaling. According to the method of the present disclosure, user equipment obtains PRG configuration information applicable to an SBFD time domain unit by receiving the first signaling sent by the network device. Therefore, in an SBFD scene, the user equipment can accurately determine the first PRG size according to a reasonable PRG parameter configuration, and accuracy of data transmission can be improved in the transmission process of the SBFD time domain unit.
