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.

摘要： Apparatus and methods for performing reduced hybrid automatic repeat request (HARQ) operations for a user equipment (UE) during a data communications session, e.g., for voice over LTE (VoLTE) communications. The UE can initially inform the network, via an enhanced NodeB (eNodeB), that the UE is capable of performing advanced HARQ functions. The eNodeB can further evaluate various network conditions to determine when reduced HARQ operations should be employed. When network conditions allow, the eNodeB can transmit an RRC message to the UE, including reduced HARQ timeline configuration information. Thereafter, the UE and the eNodeB can collaborate to institute the reduced HARQ timeline to schedule an application data retransmission during the data communications session. The reduced HARQ operations can be performed in conjunction with various semi-persistent scheduling (SPS) and connected mode discontinuous reception (C-DRX) operations, to further conserve UE device resources.

摘要： This disclosure relates to a system and method for generating single-carrier frequency division multiple access (SC-FDMA) transmissions using a high efficiency architecture. According to some embodiments, frequency resources allocated for a transmission may be determined. The allocated frequency resources may have a bandwidth less than a channel bandwidth of a frequency channel of the transmission, and may be centered around a particular frequency. The frequency may be offset from the center frequency of the channel. A baseband signal located around DC corresponding to the channel center frequency may be generated. The baseband signal may be up-converted to an RF signal using a local oscillator tuned to the frequency around which the allocated frequency resources are centered. The RF signal may be transmitted.

摘要： Methods and devices are provided for processing a received communication signal by a UE using an analog complex filter and using a single analog-to-digital converter (ADC). A control channel of the communication signal may be decoded to determine the frequency range in which a payload channel is located. The UE may then demodulate only the frequency range containing the payload channel. A complex representation of the received payload channel may be provided to the analog complex filter, with the payload channel shifted to a non-zero frequency IF. The analog complex filter may attenuate any portion of the complex representation that falls near—IF. The UE may then convert only one component path of the filtered complex representation to a digital signal. A complex representation of the digital signal may then be generated, with the payload channel shifted to DC.
