Abstract: A method, system, and apparatus are described for managing a device in a mixed wireless communication system. A device may decide to scan or not scan for a cell based on (or at least on) updating information. The updating information may be used together or individually. The updating information may be maintaining a time window in conjunction with a device's motion status, maintaining a list that tracks cell identity in areas of non-service, or utilizing network deployment information.

Abstract: Performing data communications by a Dual SIM Dual Active (DSDA) user equipment (UE), while simultaneously conducting two concurrent voice calls. The UE may receive a request to perform data communications while conducting a first voice call on a first radio and concurrently conducting a second voice call on a second radio. The UE may then determine whether one of the voice calls is currently on hold. The UE may perform the data communications using the radio on which the held call is being conducted. The UE may therefore dynamically select available slots from the first radio and the second radio for performing the data communication, based on which of the first radio and the second radio has a voice call that is currently on hold. In some embodiments, the data communications may be performed using a Long Term Evolution (LTE) protocol stack.

Abstract: A connection with a network that includes a base station (BS) may be established by a user device (UE) via a wireless connection, for conducting communications using semi persistent scheduling (SPS) in a connected discontinuous reception (C-DRX) mode. The SPS transmit periodicity may be adjusted with respect to the SPS activation command and the SPS interval UL (for uplink). Data may then be transmitted during the C-DRX On-Duration periods according to the determined SPS transmit periodicity. In some embodiments, the SPS transmit periodicity is adjusted such that following a first C-DRX On-Duration period when an SPS activation command is received, SPS data transmission occurs a specified number of subframes earlier during each subsequent C-DRX On-Duration period than in the first C-DRX On-Duration period. The SPS data transmission in each subsequent C-DRX On-Duration period may take place as soon as the UE device wakes up during the On-Duration period.

Abstract: Methods and apparatus for correcting quantization errors in signal reception based on estimated network loading including solutions for preserving cellular network performance in low noise, high interference environments. In one embodiment, a data channel is amplified with respect to other signals based on network load during periods of relatively low network utilization. Dynamic modification of the data channel's power level is configured to overcome quantization errors, rather than the true noise floor (which is insignificant in low noise environments). Such solutions provide both the fidelity necessary to enable high degrees of unwanted signaling rejection, while still preserving data channel quality.

Abstract: Adjusting search and measurement periodicity based on device motion. A wireless device may camp on a serving cell. Signal strength, signal quality, and signal to noise ratio of the serving cell may be measured. If each is above a respective threshold, and if the wireless device is stationary, the periodicities at which searches and neighbor cell measurements are performed may be adjusted (e.g., increased) from baseline periodicities.

Abstract: A method for assisting a wireless communication device to return to a first network from a second network subsequent to termination of a voice call for which a Circuit Switched Fallback procedure was performed to transition from the first network to the second network for servicing of the voice call is provided. The method can include preventing transmission of a data flow for a data service after termination of the voice call. The method can further include searching for the first network while transmission of the data flow is prevented. If the first network is found, the method can additionally include reverting to the first network and servicing the data service on the first network. If the first network is not found, the method can also include remaining on the second network and servicing the data service on the second network.

Abstract: Methods and apparatus for network-based detection and mitigation of hybrid client device reception outage events. For example, in one embodiment, a cellular device uses a single-radio solution to support circuit-switched calls on a CDMA 1X network and packet-switched calls on LTE. Periodically, the cellular device tunes away from LTE and monitors CDMA 1X activity, and vice versa. During these tuned-away periods, the network adjusts operation to mitigate adverse effects (e.g., underutilization of radio resources, synchronization loss, etc.).

Abstract: A method to control multiple radio access bearers is performed at a mobile wireless communication device when the mobile wireless communication device is connected to a radio network subsystem in a wireless communication network by first and second bidirectional radio access bearers. The mobile wireless communication device transmits a data packet on an uplink of the first bidirectional radio access bearer to the radio network subsystem. When the data packet is not correctly received by the radio network subsystem, the mobile wireless communication device retransmits the data packet repeatedly. After N retransmissions of the data packet, the mobile wireless communication device releases the first bidirectional radio access bearer while maintaining the second bidirectional radio access bearer. The first bidirectional radio access bearer provides a channel to transport packet switched data, and the second bidirectional radio access bearer provides a channel to transport circuit switched data.

Abstract: A user equipment device (UE) may implement improved communication methods which include radio resource time multiplexing, dynamic sub-frame allocation, and UE transmit duty cycle control. The UE may communicate with base stations using radio frames that include multiple sub-frames, transmit information regarding allocation of a portion of the sub-frames of a respective radio frame for each of a plurality of the radio frames, and transmit and receive data using allocated sub-frames and not using unallocated sub-frames. Additionally, the UE may operate according to a sub-frame allocation based on its current power state. The UE may transmit information to the base station and receive the sub-frame allocation based on at least the information and switch transmit duty cycles based on an occurrence of a condition at the UE. The UE may inform the network of the switch.
