Methods for preventing timing collisions in a wireless communication network include transmitting a data uplink symbol of normal duration via a first base pair using a first timing advance (TA) corresponding to the first base pair. Scheduling to transmit a second uplink symbol via a second base pair (BP) corresponding to the transmit RF chain. Predicting a timing collision will occur based on a different between the first TA and a second TA corresponding to the second BP. Preventing the timing collision by: reducing the duration of the second symbol by an adjustment amount calculated based on the first TA and the second TA; inserting a guard interval to delay transmission of the second symbol by the calculated adjustment amount; and increasing the duration of a cyclic prefix of the second symbol but refraining from transmitting a portion of the enlarged CP.
