Abstract:
Method for facilitating tracking success of a control protocol data unit transmission, comprising: authenticating a control protocol data unit; and producing a notice for a module that sends the control protocol data unit to reset a counter upon successful authentication of the control protocol data unit, as well as a corresponding wireless communications apparatus.
Abstract:
Systems and methodologies are described that facilitate avoidance of duplicative resource allocation and/or erroneous service charges via unambiguously indicating an entity responsible for quality of service (QoS) initiation. In one example, an indication is provided to a mobile device to indicate a preference for network-initiated QoS or a preference for device -initiated QoS. QoS for a data flow can be established in accordance with the indication. For instance, the mobile device initiates QoS when the indication specifies a preference for device-initiated QoS while a network establishes QoS when the indication specifies a preference for network-initiated QoS.
Abstract:
Techniques for managing resources at a wireless device are described. In one aspect, the wireless device controls applications based on resource demands and available resources. Processing demands by the applications may be monitored, and at least one of the applications may be controlled based on the processing demands and a maximum processing capacity of a processing unit executing the applications. A data application may be controlled by reducing the amount of data exchanged by the application when high processing demands are detected, and vice versa. In another aspect, the wireless device varies resource capacity to match resources demands. The processing capacity of the processing unit may be adjusted based on the processing demands. Higher clock frequency may be selected for the processing unit when the processing demands exceed a high threshold, and lower clock frequency may be selected when processing demands fall below a low threshold.
Abstract:
In accordance with a method for reducing the likelihood of deadlock in a wireless communication system, user equipment may determine that user equipment has data to transmit. The data may correspond to a scheduled flow. The user equipment may determine that a scheduled grant corresponding to the scheduled flow is insufficient to transmit at least one protocol data unit. An insufficiency indicator may be transmitted to a scheduler at least once. The insufficiency indicator may include an indication that the scheduled grant is insufficient to transmit at least one protocol data unit.
Abstract:
Managing of secondary carriers for a multicarrier user equipment (UE) is described in which the UE initiates or provides input for activation and deactivation of selected secondary cells in a carrier aggregation depending on allocation or provisioning of UE radio frequency resources.
Abstract:
Information can transfer from a transmitter to a receiver; however, the transmission can consume valuable resources. Therefore, a number of times a transmission is attempted can be tracked and compared against a threshold value. If the transmission occurs too many times - based upon the comparison - then a reset can occur. Tracking can occur for a protocol data unit and/or a control protocol data unit to determine if a reset should occur.
Abstract:
A single receiver can collect multiple protocol data units at one time originating from different sources. While it can be desirable for higher priority protocol data units to be processed, loss of data unit portions can cause confusion to the receiver. Therefore, even if a higher priority protocol data unit transfers to the receiver while a lower priority data unit is being processed, the lower priority unit can be completed before processing the higher priority unit; thus, there can be a lower likelihood of confusion among protocol data units.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided in which a probability of occurrence of an event expected to occur within a period of time is determined, where the event comprises one or more of a tune-away event and a suspension event. One or more transmission control protocol parameters are manipulated before the occurrence of the event when the probability of occurrence exceeds a threshold to increase a retransmission time out parameter value, or to maintain a desirable congestion window size. The transmission control protocol parameters may be manipulated by delaying, duplicating or dropping acknowledgements and/or by selectively dropping received packets before, during, or after the event.
Abstract:
The application relates to session management in wireless communication networks, in particular LTE networks, where a PDN connection is disconnected locally by a user equipment UE while in LTE coverage. The standards assume that the network and the UE are always in sync. However, there may be situations, not anticipated by the standards, which may lead to the UE being out of sync with the network. For example, the UE might disconnect locally, e.g. via closure of a browser on the UE), and does not inform the network, e.g. because the UE was instructed to stop sending messages on a PDN for a predetermined time period. Therefore, when the UE request to reconnect to a PDN, the network may reject the UEs request as it still thinks that the UE is connected to the PDN. The problem is solved in that in the given situation the UE performs a tracking area update TAU procedure (812) before it requests to reconnect to the PDN (814). Another solutions foresees to start a TAU procedure whenever unexpected active radio bearer contexts exist.
Abstract:
Techniques are provided for controlling downlink data transfer during carrier aggregation. For example, a method may control a secondary component carrier downlink (DL) in a wireless communication network using carrier aggregation. The method may include detecting, by a mobile entity, an event indicating a resource constraint at the mobile entity related to a data transmission from a base station to the mobile entity on a secondary component carrier of a carrier aggregation enabled connection. The method may include, in response to detecting the event, controlling the data transmission by signaling a status of the secondary component carrier DL to the base station.
