Abstract:
Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for managing state transitions of communication circuitries in wireless networks. Embodiments manage radio resource control (RRC) state transitions and/or discontinuous reception (DRX) state transitions. Other embodiments may be described and/or claimed.
Abstract:
Techniques to control paging for fixed devices are described. An apparatus may comprise a processor circuit, a device identifier component arranged for execution by the processor circuit to determine whether a device is a fixed or mobile device, and a paging component arranged for execution by the processor circuit to generate one or more control directives to modify paging parameters when the device is a fixed device. Other embodiments are described and claimed.
Abstract:
Techniques are described for a device to request a new service flow for best effort (BE) category traffic to assign a priority to the new service flow. For example, a Traffic Priority parameter in a media access control (MAC) message can be used to transmit the priority level for a new BE category service flow. The MAC message can be an AAI DSA-REQ message (specified in IEEE 802.16m draft 9 (2010)). Either a base station or a mobile station can request a new service flow using the MAC message.
Abstract:
Briefly, in accordance with one or more embodiments, a fixed device synchronizes with a downlink channel of a network, acquires a master information block including a last system update time; and executes cell selection without acquiring other system information if the last system update time is before the last system access time. Furthermore, the fixed device may listen only for system information block messages that it needs, and ignore other system information blocks. A bitmap may indicate which system information block messages should be listed to for fixed devices, and which may be ignored. In some embodiments, one or more system information blocks may be designated for fixed devices.
Abstract:
Briefly, in accordance with one or more embodiments, a fixed device performs a cell search to search for one or more cells on a network and determines a transmit power level to communicate with one of the cells of the network. The fixed device sets a frequency of updating the transmit power level for communication with a cell on the network, wherein the frequency of updating the transmit power level is reduced for the fixed device with respect to a mobile device.
Abstract:
A method and system for reducing signaling overhead during radio resource control (RRC) state transitions is disclosed. The method can include a first wireless device saving a selected RRC parameter in a memory. The selected RRC parameter can be identified based on a low frequency in which the selected RRC parameter changes. The first wireless device can set an RRC resource parameter retention timer to count a retention time duration for using the selected RRC parameter saved in the memory. The first wireless device can receive a reduced RRC connection message from a second wireless device. The reduced RRC connection message excludes the selected RRC parameter. The first wireless device can use the selected RRC parameter saved in the memory for the RRC parameter excluded in the reduced RRC connection message when the RRC resource parameter retention timer is not expired. The selected RRC parameter can be used in a RRC connection protocol.

Abstract:
Embodiments of user equipment (UE) and methods for application-agnostic discontinuous reception (DRX) triggering are generally described herein. In some embodiments, a UE is configured to monitor buffer status history and traffic activity history, and trigger DRX mode activation based on the buffer status and the traffic activity history. In some embodiments, the UE may determine a probability, based on the buffer status history and the traffic activity history, that a level of traffic activity that cannot be handled during DRX mode would occur. In these embodiments, the UE may trigger DRX mode activation when the probability is below a threshold.
Abstract:
An apparatus and method for initiating discontinuous reception (DRX) operation in a user equipment (UE) are disclosed herein. Applications running on the UE are monitored by the UE to identify one or more inactivity trigger events associated with the application(s). The UE includes an application-radio cross layer to process the application information, including the inactivity trigger event, for use by a radio layer. The radio layer of the UE determines initiation of the DRX operation in accordance with the application information, including the inactivity trigger event, provided by the application-radio cross layer and device characteristics information.
Abstract:
Briefly, in accordance with one or more embodiments, data transmitted from a transmitter is received in a downlink channel, and channel quality data is fed back to the transmitter in a first uplink channel or in a second uplink channel. Channel quality data is feedback at a lower rate on the first uplink channel and channel quality data is feedback at a higher rate on the second uplink channel in the event there is a higher amount of data to be fed back. Link adaptation may be utilized to select a transmission rate on the second uplink channel, wherein the transmission rate is selected based at least in part on a channel condition or a user location.
