Timing advance for grantless uplink transmission

Abstract:

Described is an apparatus of an Evolved Node-B (eNB) operable to communicate with a User Equipment (UE) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to determine a first Timing Advance (TA) for Scheduled Uplink (SUL) transmission. The circuitry may also be operable to determine a second TA for Grantless Uplink (GUL) transmission. The second circuitry may be operable to generate an SUL transmission for transmission at a timing based upon the first TA. The second circuitry may also be operable to generate a GUL transmission for transmission at a timing based upon the second TA.
