27 Claims

1. A method for wireless communication at a user equipment (UE), comprising:

receiving an indication of an uplink transmission timing pattern configuration for use by the UE in transmitting uplink transmissions, wherein receiving the indication comprises receiving a radio resource control message, wherein the indication of the uplink transmission timing pattern configuration comprises one or more blank symbol information elements in the radio resource control message, the radio resource control message also including an indication of a specific carrier on which one or more uplink carrier switching periods are used for the retuning between the first carrier and the second carrier;

identifying that the UE is to use both a first carrier and a second carrier during a single uplink transmission mode, wherein the UE transitions between sending the uplink transmissions on the first carrier and on the second carrier;

identifying one or more blank uplink symbols based at least in part on one or more blank symbol information elements received with the uplink transmission timing pattern configuration, wherein the one or more blank uplink symbols correspond to the timing of the one or more uplink carrier switching periods on the specific carrier for the retuning between the first carrier and the second carrier;

determining, based at least in part on the uplink transmission timing pattern configuration, a timing of one or more uplink carrier switching periods for retuning between transmissions on the first carrier and on the second carrier; and

transmitting, during the single uplink transmission mode, on both the first carrier and the second carrier in accordance with the uplink transmission timing pattern configuration and the one or more uplink carrier switching periods.
