1. A method implemented by a user equipment in a wireless communication network of synchronizing a periodic data transmission from the user equipment to a base station, said method comprising:
receiving, from the base station, a Semi-Permanent Scheduling (SPS) configuration for the periodic data transmission, said SPS configuration including an SPS period and an offset;
receiving, from the base station, an allocation of available SPS resources in said SPS period for the periodic data transmission, wherein a number of SPS resources allocated for the periodic data transmission exceeds the number of repetitions in each data transmission;
receiving a data transmission from or sending a data transmission to the base station on allocated SPS resources according to the SPS configuration; and
receive, from the base station, an adjusted SPS configuration based on a timing of the data transmission, the adjusted SPS configuration comprising an adjusted offset to synchronize the SPS period with the periodic data transmission.
