    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.

    摘要： 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.

    摘要： 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.

    摘要： Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc. can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

    摘要： 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.

    摘要翻译： 单个接收机可以一次收集源自不同来源的多个协议数据单元。 虽然可以期望处理更高优先级的协议数据单元，但数据单元部分的丢失可能导致对接收机的混淆。 因此，即使在处理较低优先级的数据单元时，较高优先级的协议数据单元传送到接收机，则可以在处理较高优先级单元之前完成较低优先级单元; 因此，在协议数据单元之间可能存在较低的混淆可能性。
