Abstract: Apparatus, system and methods for evaluating link quality within a cellular system. A user equipment (“UE”) is connected to a network, wherein the UE communicates data to the network on an uplink (“UL”) link. The UE determines a requested buffer size for a UL communication, determines a transport block size for the UL communication based on a primary set of allocation parameters, and compares the requested buffer size to the transport block size to determine if a data rate for the UL communication satisfies a threshold. When the data rate satisfies the threshold, the UE identifies the UL link as a good quality link and sends acceptable link quality feedback to the network. When the data rate does not satisfy the threshold, the UE performs a further action to test a quality of the UL link.

Abstract: A method for reducing power consumption by a wireless communication device is disclosed. The method can include the wireless communication device performing a first measurement of an alternative cell during a first measurement gap; sending a first measurement report generated based on the first measurement to the serving cell; storing the first measurement report; determining a mobility state of the wireless communication device; comparing the mobility state to a mobility threshold criterion; resending the first measurement report to the serving network as a report for a second measurement gap in an instance in which the mobility state satisfies the mobility criterion; and performing a second measurement of the alternative cell during the second measurement gap and sending a second measurement report generated based on the second measurement to the serving cell in an instance in which the mobility state does not satisfy the mobility threshold criterion.

Abstract: 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.

Abstract: A method for facilitating reselection by a wireless communication device to a first network from a second network after termination of a voice call for which a CSFB procedure was performed is provided. The method can include performing measurement of the first network while connected to the first network and performing measurement of the second network during the voice call. The method can further include determining based at least in part on one or more of the measurements that the wireless communication device is in a mobility state. The method can additionally include deriving a predicted signal quality of the first network after termination of the voice call based at least in part on the measurement of the first network and using the predicted signal quality to determine whether to release a connection to the second network and attempt reselection to the first network.
