Abstract
Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for assigning transmission power to one or more components carriers in an uplink transmission utilizing carrier aggregation. In one embodiment, power is assigned to a component carrier based on the priority level of the component carrier. In another embodiment, power is assigned based on absolute priority order. In yet another embodiment, power is assigned based on relative priority order.
Claims25
One or more computer-readable media having instructions that, when executed, cause a mobile device to:
- set a power level of a transmission of a random access channel in the mobile device at a low value;
- set an occurrence threshold and a occurrence count for the random access channel;
- increment the occurrence count when the mobile device transmits on the random access channel;
- compare the occurrence count to the occurrence threshold;
- and
- set the power level of the random access channel transmission in the mobile device at a high value based on comparison of the occurrence count to the occurrence threshold.
A mobile device comprising:
- a transmitter configured to transmit a first random access channel on a first carrier and a second random access channel on a second carrier;
- a processor configured to determine a first occurrence count for the first random access channel and compare the first occurrence count to an occurrence threshold;
- and
- a power controller configured to set a power level of transmissions of the first random access channel on the first carrier at a low value, and change the power level of the transmissions of the first random access channel to a high value based on the comparison of the first occurrence count to the occurrence threshold.
A method of allocating power in a transmitter of a mobile device, the method comprising:
- detecting a first transmission from the mobile device of a channel on a first carrier,
- detecting a second transmission from the mobile device of the channel on a second carrier,
- detecting an available power level of the mobile device,
- determining a first intended power level of the first transmission and a second intended power level of the second transmission that is higher than the first intended power level,
- assigning a first actual power level to the first transmission, and
- assigning a second actual power level that is the difference between the first actual power level and the available power level to the second transmission.
A processor configured to perform the steps of:
- assigning a channel to a first carrier for a first transmission of the channel and assigning the channel to a second carrier for a second transmission of the channel that at least partially overlaps the first transmission in time;
- determining an available transmission power level, a first intended power level of the first transmission, and a second intended power level of the second transmission;
- directing a transmitter to transmit the first transmission at the first intended power level based on a comparison of both the first intended power level and the second intended power level to the available transmission power level;
- and
- directing a transmitter to transmit the first transmission at a first actual power level that is less than the first intended power level based on the comparison.
