Abstract
Example embodiments of the present disclosure relate to communication. According to embodiments of the present disclosure, a network device transmits configuration information for one or more frequency hopping modes to a terminal device. The terminal device determines which frequency hopping mode is used and also determines a plurality of frequency hopping positions based on the configuration information. In this way, it can have more frequency hopping positions which achieve more frequency diversity gain and benefit to coverage enhancement. Further, the frequency hopping frequency is configured more flexible.

- one or more processors configured to process the instructions to control the UE to:
- receive first information, the first information indicating a first number of slots for an inter-slot frequency hopping for an uplink channel;
- and
- determine a starting resource block (RB), during a current slot within a radio frame, based on a numerical formula:
