TLDR
In this paper, a method and system for scheduling data in the down, or forward, link, on a per packet basis in a wireless telecommunications network is presented, where the scheduler determines the order of packets to be sent from multiple queues based on per IP QoS, real time channel condition and real time buffer occupancy.Abstract:
A method and system for scheduling data in the down, or forward, link, on a per packet basis in a wireless telecommunications network. The scheduler determines the order of packets to be sent from multiple queues based on per IP QoS, real time channel condition and real time buffer occupancy. The scheduler determines the necessary support link adaptation on a per packet basis based on per packet QoS and the channel condition. The scheduling system and method take into consideration both upper layer per packet QoS, for example packet delay bound, and the real time channel condition (C/I) for each mobile terminal. The method of the present invention also determines the layer 2 frame length for each scheduled packet.read more

Method and apparatus for forward power control in a communication system
TL;DR: In this article, the data transmission is scheduled based on an Access Terminal initiated forward power control, which reduces forward link rate quantization loss due to excess transmit power, and the Access Point then reduces its transmit power by an appropriate amount when serving that Access Terminal.

Rule set conflict resolution
TL;DR: In this article, a flow manager may receive prioritized packet flow rules from multiple prioritized network services where each flow rule may comprise a packet filter and a prioritized action list.

Method and apparatus for providing differentiated quality of service for packets in a particular flow
TL;DR: In this paper, each packet in a particular flow is classified into one of a plurality of quality of service (QoS) classes based on information about each packet and each packet is then adaptively processed based on the QoS class for each packet.

Method And Apparatus For Scheduling And Modulation And Coding Selection For Supporting Quality Of Service In Transmissions On Forward Shared Radio Channels
TL;DR: In this article, a process and system for controlling selection of which MS is to receive the next packet data transmission on a forward channel and selection of the plural MCS is to be used for the packet data transmissions on the forward channel is presented.
Patent
Rule set verification
TL;DR: In this paper, a flow manager may receive prioritized packet flow rules from one or more network services where each rule may include a packet filter and prioritized actions, and each action of a packet flow rule may be either terminating or nonterminating.
