Carrier Aggregation Secondary Component Carrier Management

摘要

This disclosure relates to management of a secondary component carrier by a wireless device when using carrier aggregation. According to one embodiment, a primary component carrier for communication between a base station and a wireless device may be configured according to a first wireless communication technology. A secondary component carrier may also be configured. The wireless device may detect a trigger condition to deactivate the secondary component carrier. In response, the wireless device may modify its feedback to the base station with respect to channel conditions for the secondary component carrier to cause the base station to deactivate the secondary component carrier.

主权项

1. A wireless user equipment (UE) device, comprising:
a first RF communication chain; a second RF communication chain; and a processing element operably coupled to the first and second RF communication chains, wherein the UE is configured to:
communicate with a first network according to a first radio access technology (RAT) via a base station using a primary component carrier and a first communication chain;receive configuration information for a secondary component carrier from the base station;receive an indication to activate the secondary component carrier from the base station;acknowledge the indication to activate the secondary component carrier if a second RF communication chain is not in use when the indication to activate the secondary component carrier is received;communicate with the first network according to the first RAT using the secondary component carrier and the second RF communication chain;detect a trigger condition to deactivate the secondary component carrier; andtransmit an indication causing the base station to deactivate the secondary component carrier based on detecting the trigger condition.
