Apparatus and method for sub-band time-frequency configuration
By employing a subband time-frequency division (SBFD) scheme in a TDD wireless communication system, frequency resources are divided into non-overlapping downlink and uplink subbands, solving the problems of reduced uplink coverage and capacity in TDD systems, and achieving more efficient resource utilization and improved communication quality.

AI Technical Summary
Technical Problem
The problems of reduced uplink coverage, reduced capacity, and increased latency in existing TDD wireless communication systems are mainly due to the limited allocation of time resources.
Method used
The Subband Time-Frequency Division (SBFD) scheme is adopted to divide the frequency resources of time symbols and/or time slots into non-overlapping downlink and uplink subbands, thereby increasing the allocation of uplink time and frequency resources.
Benefits of technology
The SBFD scheme improves the coverage and capacity of uplink communication, reduces latency, and optimizes resource utilization in wireless communication systems.
