Abstract
A wireless relay wirelessly receives user data from User Equipment (UE) using a UE uplink Carrier Aggregation (CA) configuration. The wireless relay wirelessly transfers the user data using a relay uplink. The wireless relay determines available Power Headroom (PHR) for the relay uplink and translates the available PHR into a new UE uplink CA configuration. The wireless relay wirelessly receives additional user data from the UE using the new UE uplink CA configuration.
Claims20
A method of operating a wireless communication system to control uplink Carrier Aggregation (CA), the method comprising:
- a wireless relay wirelessly receiving user data from User Equipment (UE) using a UE uplink CA configuration;
- the wireless relay wirelessly transferring the user data using a relay uplink;
- the wireless relay determining available Power Headroom (PHR) for the relay uplink and translating the available PHR into a new UE uplink CA configuration;
- and
- the wireless relay wirelessly receiving additional user data from the UE using the new UE uplink CA configuration.
A wireless relay to control uplink Carrier Aggregation (CA), the wireless relay comprising:
- a communication transceiver configured to wirelessly receive user data from User Equipment (UE) using a UE uplink CA configuration;
- the communication transceiver configured to wirelessly transfer the user data using a relay uplink;
- a data processor configured to determine available Power Headroom (PHR) for the relay uplink and translate the available PHR into a new UE uplink CA configuration;
- and
- the communication transceiver configured to wirelessly receive additional user data from the UE using the new UE uplink CA configuration.
