Uplink Frequency Hopping Step Determination for PUCCH Stability

The patent changes the frequency hopping step calculation parameter from being system bandwidth-dependent to being PUCCH capacity-dependent. Specifically, it introduces a new calculation formula where the frequency hopping step is determined by the PUCCH capacity parameter, which directly reflects the number of PUCCHs to be transmitted. This parameter change ensures that the frequency hopping step remains stable and appropriate regardless of whether the PUCCH capacity is large or small, thereby resolving the contradiction between transmission performance and frequency hopping step stability.

The patent applies local quality by making the frequency hopping step adaptive to local PUCCH capacity conditions. Instead of using a uniform frequency hopping step for all terminals, the patent calculates the frequency hopping step based on the specific PUCCH capacity of each terminal. This allows terminals with large PUCCH capacity to have larger frequency hopping steps (improving frequency domain diversity) while terminals with small PUCCH capacity have smaller frequency hopping steps (maintaining stability), thereby resolving the contradiction between frequency domain diversity effect and frequency hopping step consistency.

The patent changes the determining parameter of frequency hopping step from system bandwidth to PUCCH capacity. By using PUCCH capacity as the basis for calculation, the patent ensures that terminals with small PUCCH capacity receive appropriate (smaller) frequency hopping steps that maintain their frequency hopping stability, while still achieving adequate frequency domain diversity through the optimized calculation formula. This parameter change resolves the contradiction between frequency hopping step stability and frequency domain diversity effect for terminals with small PUCCH capacity.
