摘要:
Methods, devices, and instructions stored in non-transitory computer-readable medium are provided for adaptively adjusting when a mobile device requests fast dormancy (FD) by determining when applications executing on the mobile device stop using a connection to a cellular telecommunications network. An adaptive fast dormancy controller function executing on a processor of the mobile device monitors network traffic activity by the applications. The adaptive fast dormancy controller function may determine that an open network connection should be released using a device traffic inactivity timer that times durations of network inactivity by applications. The duration of the device traffic inactivity timer may be adjusted based upon observed application and/or network conditions. Multiple device traffic inactivity timers may be used to enable timing traffic inactivity of each application or groups of applications executing on the mobile device.

Methods, systems, and devices are disclosed for providing services, such as voice services, within flexible bandwidth systems. In general, the scaling of one or more aspects of a flexible bandwidth system may be compensated for through altering one or more aspects within a code domain. The tools and techniques may include scaling spreading factors (with rate matching tuning in some embodiments), multi-code transmission, code rate increases, AMR codec rate adjustments, and/or higher order modulation. Subframe decoding approaches for the reception scheme may also be utilized. These tools and techniques can be flexibly implemented on the mobile device and/or base station side. Some embodiments may also minimize the latency introduced by the transmission and/or reception process. Flexible bandwidths systems may utilize portions of spectrum that may be too big or too small to fit a normal bandwidth waveform.

Methods, systems, and devices for supporting voice communications in a wireless communications system are provided. Some embodiments utilize multiple code channels to transmit the voice frames. These embodiments include parallel multi-code embodiments, offset multi-code embodiments, and multi-user multi-code embodiments. Some embodiments utilize flexible carrier bandwidths systems that may utilize portions of spectrum that may not be big enough to fit a normal bandwidth waveform. Some embodiments transmit and receive a subset of subframes of voice frames received over flexible bandwidth code channels. In some embodiments, a subset of subframes based on a flexible bandwidth scaling factor of one or more flexible bandwidth code channels is transmitted. The receiver may decode the voice frame based on the received subset of subframes. An outer loop power control set-point may be adjusted to provide a predetermined frame error rate based on the number of transmitted subframes.
摘要:
A mobile device provides first information to an access point over an out-of-band wireless link. The access point uses the first information to coarsely synchronize with a macrocell base station. The access point transmits a low power pilot signal that is formed using a pseudo-random noise (PN) sequence. The mobile device uses the out-of-band wireless link to provide second information to the access point that indicates a PN phase of the pilot signal with respect to a reference time point. The access point uses the second information to finely synchronize with the macrocell base station. The mobile device communicates with a mobile operator core network through the access point using an in-band wireless link to the access point. The mobile device compensates for propagation delay when obtaining time information. The mobile device provides additional information to the access point, which the access point uses to adjust for continued clock drift.

摘要:
Methods, systems, and devices for separating signaling data and traffic data onto separate carriers for wireless communications systems are provided. Some embodiments utilize flexible bandwidth that may utilize portions of spectrum that may not be big enough to fit a normal waveform through utilizing flexible waveforms. Flexible bandwidth systems may lead to reduced data rate on the signaling or other channels. Separating the signaling and the data traffic into different flexible bandwidth carriers so that assigned resources can be customized to different traffic patterns may address this issue. In some embodiments, the signaling data is received and/or transmitted over a first carrier separate from any other traffic data. For example, the signaling data may be received and/or transmitted over the first band carrier without any other traffic data. The traffic data and/or network data associated with the signaling data may be received and/or transmitted over a separate, second carrier.

A novel message exchange protocol is disclosed. In one example, a method of transmitting data includes generating, with a wireless device, an application data message for an application; evaluating one or more criteria for determining whether to send the application data message via a data radio bearer (DRB) channel or via a signaling radio bearer (SRB) channel that communicatively couples the wireless device to a network resource; and based on determining to send the application data message via the SRB channel, sending the application data message to the network resource via the SRB channel.

摘要:
Methods, systems, and devices are described for making scaling adjustments with respect to a fractional subsystem in a wireless communications system. To handle the effects of scaling associated with fractional bandwidth systems, different adjustments may be made to maintain certain quality of service (QoS) requirements, for example. Scaling adjustments may include identifying a scaling factor for the fractional subsystem and a parameter and/or a timer associated with the fractional subsystem. An adjustment associated with the parameter and/or timer may be determined based on the scaling factor. The adjustment may be applied with respect to the parameter and/or timer for at least a portion of the fractional subsystem or another portion of the wireless communications system.
