Dynamic antenna tuner setting for carrier aggregation scenarios

摘要

Apparatus and methods for dynamically adjusting radio frequency circuitry in a wireless communication device are disclosed. The wireless communication device can receive downlink communication using carrier aggregation through a primary component carrier and a secondary component carrier. When carrier aggregation is not enabled, the wireless communication device adjusts the radio frequency circuitry based on default values. When carrier aggregation is enabled, the wireless communication device evaluates radio frequency conditions for the primary and secondary component carriers and adjusts the radio frequency circuitry based on whether uplink and/or downlink communication is power constrained. When uplink communication is power constrained, the wireless communication device adjusts the radio frequency circuitry for optimal performance via the primary component carrier, and when uplink communication is not power constrained, the wireless communication device adjusts the radio frequency circuitry for optimal performance via the combination of the primary and secondary component carriers used for carrier aggregation.

1. A method to adjust radio frequency circuitry in a wireless communication device, the method comprising the wireless communication device at least:
receiving one or more downlink communications from a wireless network; determining whether carrier aggregation is enabled; when carrier aggregation is not enabled, adjusting the radio frequency circuitry based on default setting values; and when carrier aggregation is enabled:
evaluating radio frequency conditions for a primary component carrier and for a secondary component carrier used for carrier aggregation;determining whether uplink communication is power constrained;when uplink communication is power constrained, adjusting the radio frequency circuitry to maximize power transfer over a set of radio frequencies through the primary component carrier; andwhen uplink communication is not power constrained, adjusting the radio frequency circuitry to maximize power transfer over a set of radio frequencies through a combination of the primary component carrier and the secondary component carrier,wherein the wireless communication device determines whether uplink communication is power constrained based at least in part on whether:
an uplink performance metric is less than an uplink performance threshold and a downlink performance metric is greater than a downlink performance threshold, ora downlink received signal strength exceeds a downlink signal strength threshold and a number of uplink random access channel (RACH) failures occur.
