Abstract: A method for facilitating in-device coexistence between wireless communication technologies on a wireless communication device is provided. The method can include transmitting data traffic from the wireless communication device via an aggressor wireless communication technology; determining occurrence of an in-device interference condition resulting from transmission of the data traffic via the aggressor wireless communication technology interfering with concurrent data reception by the wireless communication device via a victim wireless communication technology; and reducing a bit rate of the data traffic transmitted via the aggressor wireless communication technology in response to the in-device interference condition.

Abstract: Wireless communication devices (UEs) may include multiple receive (RX) chains and associated antennas, and at least one transmit (TX) chain co-located with one of the RX chains. The UE may track instant fading of the antenna gain(s) during reception of packets from an associated access point (AP) device to which the UE intends to transmit packets. The UE may also track long term antenna gain(s), using any packets received at the multiple RX chains within the UE. At a switching occasion, a decision is made by the UE whether to switch antennas. If the instant fading detection is based on packets received no later than a specified time period prior to the switching occasion, then the UE may make the switching decision based on the results of the instant fading tracking. Otherwise, the UE may make the switching decision based on the results of the long term antenna gain tracking.

Abstract: Apparatus and methods are disclosed for performing delayed hybrid automatic repeat request (HARQ) communications in the downlink (DL) to reduce power consumption for a user equipment (UE) during a connected mode discontinuous reception (C-DRX) cycle. An enhanced NodeB can be configured to monitor a physical uplink control channel (PUCCH) for DL HARQ information to determine when the PUCCH contains a negative acknowledgement (NACK) message, and in response to determining that the PUCCH contains a NACK message, the eNodeB can wait until a next C-DRX ON duration to transmit a HARQ DL retransmission. The eNodeB can also determine whether or not to bundle the HARQ DL retransmission in consecutive transmission time intervals, based on a signal to interference plus noise ratio (SINR) associated with the UE.

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 single chip mobile wireless device capable of receiving and transmitting over one wireless network at a time maintains registration on two wireless communication networks that each use different communication protocols in parallel. Periodically, the mobile wireless device tunes one or more receivers from a first wireless network to a second wireless network in order to listen for paging messages addressed to the mobile wireless device from the second wireless network. The first wireless network suspends allocation of radio resources to the mobile wireless device based on receipt of a suspension message from the mobile wireless device, or based on knowledge of a paging cycle for mobile wireless device in the second wireless network, or based on detection of an out of synchronization condition with the mobile wireless device.

Abstract: 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.

Abstract: A method of modulating transmission power to facilitate in-device coexistence between wireless communication technologies is provided. The method can include determining a scheduled time period during which data is received by a device via a first wireless communication technology. The method can further include reducing a transmission power of a transmission from the device via a second wireless communication technology to a threshold level prior to the scheduled time period and controlling the transmission power so that the transmission power does not exceed the threshold level during the scheduled time period. The method can additionally include, subsequent to the time period, increasing the transmission power to a level exceeding the threshold level.
