A method performed by a user equipment, the method comprising: determining, by the user equipment, an interference condition that is local to the user equipment, the determined local interference condition attributable to a first configuration of wireless-communication hardware (204, 206, 208, 210) of the user equipment that is used by the user equipment when concurrently transmitting: first data from the user equipment to a first base station using a first set of subcarriers, the first set of subcarriers associated with a first radio access technology; and second data from the user equipment to a second base station using a second set of subcarriers, the second set of subcarriers associated with a second radio access technology; determining, by the user equipment, a second configuration of the wireless-communication hardware (204, 206, 208, 210) of the user equipment that mitigates the determined local interference condition and that is used by the user equipment, the determining when concurrently transmitting: the first data from the user equipment to the first base station using a third set of subcarriers, the third set of subcarriers associated with the first radio access technology and different from the first set of subcarriers; and the second data from the user equipment to the second base station using a fourth set of subcarriers, the fourth set of subcarriers associated with the second radio access technology and different from the second set of subcarriers; and transmitting, by the user equipment to the first base station and the second base station, a request message having contents that indicate to the first base station and the second base station one or more of a duty cycle, a transmission pattern, or a transmission time interval that the user equipment will use when transmitting the first data using the third set of subcarriers and the second data using the fourth set of subcarriers. determining, by the user equipment, an interference condition that is local to the user equipment, the determined local interference condition attributable to a first configuration of wireless-communication hardware (204, 206, 208, 210) of the user equipment that is used by the user equipment when concurrently transmitting: first data from the user equipment to a first base station using a first set of subcarriers, the first set of subcarriers associated with a first radio access technology; and second data from the user equipment to a second base station using a second set of subcarriers, the second set of subcarriers associated with a second radio access technology; first data from the user equipment to a first base station using a first set of subcarriers, the first set of subcarriers associated with a first radio access technology; and second data from the user equipment to a second base station using a second set of subcarriers, the second set of subcarriers associated with a second radio access technology; determining, by the user equipment, a second configuration of the wireless-communication hardware (204, 206, 208, 210) of the user equipment that mitigates the determined local interference condition and that is used by the user equipment, the determining when concurrently transmitting: the first data from the user equipment to the first base station using a third set of subcarriers, the third set of subcarriers associated with the first radio access technology and different from the first set of subcarriers; and the second data from the user equipment to the second base station using a fourth set of subcarriers, the fourth set of subcarriers associated with the second radio access technology and different from the second set of subcarriers; and the first data from the user equipment to the first base station using a third set of subcarriers, the third set of subcarriers associated with the first radio access technology and different from the first set of subcarriers; and the second data from the user equipment to the second base station using a fourth set of subcarriers, the fourth set of subcarriers associated with the second radio access technology and different from the second set of subcarriers; and transmitting, by the user equipment to the first base station and the second base station, a request message having contents that indicate to the first base station and the second base station one or more of a duty cycle, a transmission pattern, or a transmission time interval that the user equipment will use when transmitting the first data using the third set of subcarriers and the second data using the fourth set of subcarriers.
