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

  • receiving from a user device a request to reconfigure already-active uplink semi-persistent scheduling (SPS);

    wherein the already-active uplink SPS grants the user device 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 the request is specified in at least one of the following portions of a media access control (MAC) protocol data unit (PDU);

    a reserved bit of a header of the MAC PDU;

    a control-element field of a payload of the MAC PDU; and

    a padding field of the payload; and

    reconfiguring the already-active uplink SPS, the reconfiguring comprising modifying the time-interval parameter based, at least in part, on the information.
