System and method for small traffic transmissions

A mobile device comprising:

• a processor;
• and
• a computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• receive, through a first slow-signaling channel, information indicating a transmission resource associated with an access space comprising a time-frequency resource of an uplink channel, the information further indicating an access code associated with the access space, the first slow-signaling channel being different than a physical downlink control channel (PDCCH) and communicated less frequently than the PDCCH;
• and
• transmit a data packet over the time-frequency resource of the uplink channel using the access code and a predefined modulation and coding scheme (MCS) setting without receiving a dynamic scheduling grant signaling for the time-frequency resource over the PDCCH, wherein an MCS setting is updated through a second slow-signaling channel after transmitting the data packet, the second slow-signaling channel being different than the PDCCH and communicated less frequently than the PDCCH.

A base station comprising:

• a processor;
• and
• a computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• send to a mobile device through a first slow-signaling channel, information indicating a transmission resource associated with an access space comprising a time-frequency resource of an uplink channel, the information further indicating an access code associated with the access space, the first slow-signaling channel being different than a physical downlink control channel (PDCCH) and communicated less frequently than the PDCCH;
• and
• receive a data packet over the time-frequency resource of the uplink channel using the access code and a predefined modulation and coding scheme (MCS) setting without sending a dynamic scheduling grant signaling for the time-frequency resource over the PDCCH, wherein the MCS setting is updated through a second slow-signaling channel after receiving the data packet, the second slow-signaling channel being different than the PDCCH and communicated less frequently than the PDCCH.
