Scheduling systems and methods for wireless networks

A method comprising, by a base station in a wireless network:

• configuring uplink semi-persistent scheduling (SPS) for a user equipment;
• receiving from a user equipment a request to reconfigure the already-active uplink SPS,
• wherein the already-active uplink SPS grants the user equipment a resource block allocation (RBA) and a modulation and coding scheme (MCS) for periodic uplink transmissions,
• wherein the already-active uplink SPS comprises a time-interval parameter, the time-interval parameter specifying a time interval between the periodic uplink transmissions,
• wherein the request comprises information related to a proposed adjustment of the time-interval parameter;
• and
• sending a reconfigured already-active uplink SPS to the user equipment, the reconfigured already-active uplink SPS comprising a modified time-interval parameter based, at least in part, on the information.
