摘要:
Methods and apparatus for downlink rate control by a user equipment (UE) (e.g., when an overload condition happens at the UE) are provided. For example, the UE may experience CPU overload, CPU near-overload, memory overload, memory near-overload, overheating or near-overheating. For certain aspects, the UE may simulate a “degraded channel” in order to cause an eNodeB to lower a transmission rate or block-size as it would in response to receiving an indication of bad channel conditions. The UE may simulate a degraded channel by modifying a channel quality indicator (CQI) and transmitting negative acknowledgment (NACK) messages to the eNodeB. Therefore, the eNodeB may be responsible for guaranteeing quality of service (QoS) based on the new degraded channel condition. In other aspects, UE downlink flow control is achieved by dropping hybrid automatic repeat request (HARM) packets or reducing a radio link control (RLC) receive window size when an overload condition occurs.

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.

An apparatus and method for distributed data processing is described herein. A main processor programs a mini-processor to process an incoming data stream. The mini-processor is located in close proximity to hardware components operating on the input data stream. A copy engine is also provided for copying data from multiple protocol data units in a single copy operation.

A method for wireless communications is provided. The method includes triggering a handover process across a wireless network and generating handover messages on more than a single communications process to facilitate receipt of the handover messages. The method can include increasing the power associated with a communications channel in order to facilitate receipt of the handover messages and can also include generating multiple messages that also are increased in power by the communications channel.

A technique for uplink data throttling includes buffer status report (BSR) scaling. A target data flow rate may be determined based on at least on condition of a wireless device. The buffer status report may be adjusted to cause the target flow rate and transmitted by the wireless device. The wireless device may then receive a flow control command based on the buffer status report.

Multiple memory pools are defined in hardware for operating on data. At least one memory pool has a lower latency that the other memory pools. Hardware components operate directly on data in the lower latency memory pool.

A method for reprocessing data in a radio protocol layer is described. The method includes communicating using a first radio access technology. Data in a processed data buffer of a first radio access technology protocol layer is reprocessed. The reprocessed data is forwarded to an unprocessed data buffer. A trigger for a handover from the first radio access technology to a second radio access technology may be detected. A trigger for a radio connection release may also be detected.

Systems and methods for wireless communications are provided. These include data deciphering components, interrupt processing components, adaptive aggregations methods, optimized data path processing, buffer pool processing, application processing where data is formatted in a suitable format for a destination process, and Keystream bank processing among other hardware acceleration features. Such systems and methods are provided to simplify logic designs and mitigate processing steps during wireless network data processing.
摘要:
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.
