摘要： Systems and methods for decreasing delays and thereby improving the performance of data transmissions in wireless communication systems by enabling increased data transmission rates to be selected for a reverse link between an access terminal and an access network. The new data rate is selected from several limiting rates, including a data-justified rate and a ramp-up-limited rate. In one embodiment, the data-justified rate is constrained to decrease in a controlled manner and cannot suddenly drop to 0. In another embodiment, the ramp-up-limited rate is allowed to return quickly to a sticky rate if the system is not busy rather than having to ramp up to the sticky rate according to the standard probabilities.

摘要： The disclosure relates to video rate adaptation techniques that may use information from a medium access control (MAC) layer and radio link protocol (RLP) layer. The techniques may greatly reduce video delay by adjusting video encoding rate. For real-time video telephony (VT) applications, these techniques may provide graceful quality degradation and improve user experience, especially when the channel conditions degrade.

摘要： The disclosure relates to reverse link lower layer assisted video error control. A method may encode video data, form a packet with the encoded video data, and transmit the packet across a wireless channel to an access network. A medium access control (MAC) layer may receive a negative acknowledgement (NAK) from the access network. The method may determine whether the received NAK is associated with a packet that contains video data. If the received NAK is associated with a packet that contains video data, the method may perform error control.

摘要： In a particular embodiment, a method is disclosed that includes receiving a feedback message at a transmitter, the feedback message including an indication of a magnitude of congestion and a sustainable rate of data transmission at a receiver. The method also includes determining a decongestion rate and a decongestion time based on at least one of the sustainable rate of data transmission and the magnitude of congestion when the magnitude of congestion satisfies a threshold value. The method further includes sending data at the decongestion rate from the transmitter to the receiver for the decongestion time. The method also includes adjusting a data transmission rate at the transmitter to the sustainable rate of data transmission after the decongestion time is ended.

摘要： An Access Network (AN) can send an acknowledge message (ACK) to an Access Terminal (AT) to indicate that the AN has successfully decoded the data received in the first set of slots of the first data packet. The AN can send a negative acknowledge message (NAK) to the AT to indicate that the AN has not successfully decoded the data received in the first set of slots of a first data packet. Based upon receipt of the NAK, the AT can resend the data by sending a second set of slots of the first data packet containing redundant data. Based upon receipt of the ACK, the AT can send a first set of slots of another packet. The AT can gate off for a predetermined period of time after sending the first set of slots of a first packet and before sending a next set of slots.

摘要： A method and apparatus for determining the data rate of a reverse link communication of an access terminal includes receiving a reverse activity bit (RAB) from an access point in the communication system, and passing the RAB to a digital filter to produce a filtered RAB. In one embodiment, the reverse link data rate is determined based on the filtered value of the RAB. Furthermore, a processor in the access terminal may determine whether the access terminal is in an idle mode, and passing a non-busy state value of the RAB to the digital filter when the access terminal is in the idle mode. The filtered RAB may be compared to a threshold to determine a mode of reverse link data rate determination. The mode defines a set of criteria for an aggressiveness level of increasing or decreasing the reverse link communication data rate. The processor, therefore, determines the data rate based on the filtered reverse activity bit in accordance with the determined mode.
