Abstract

Methods, apparatus, and systems for enabling a flexible frequency hopping mechanism are described. In one example aspect, a wireless communication method is disclosed. The method includes receiving, by a communication device, a first message from a network device. The first message comprises a list of frequency hopping offsets and a value indicating a number of repetitions of a data transmission. The method also includes receiving, by the communication device, a second message selecting a frequency hopping offset from the list of frequency hopping offsets and applying multiple frequency hopping offsets to the number of repetitions of the data transmission. The multiple frequency offsets are determined according to a rule associated with the selected frequency hopping offset.
