Before a request is sent through the network, the request is inspected in order to derive the amount of work that the request would generate in the network. A traffic manager queries the amount of work in that request compared to the amount of work that the network can support and generates a number of traffic envelopes. Based on the results of this query, “task pruning” may be implemented to break the request into smaller manageable task that fit into the traffic envelopes. Task pruning may also enable only a subset of the work to be performed. Thus, a measure of the amount of work, rather than the amount of data, within a request is considered when scheduling the request.2008-09-04

20080212512Method and Device for Indirect Communication Within a WiMAX Network - A method for indirect communication in a WiMAX network includes: determining a wireless broadband terrestrial transmission scheme by a base station; transmitting, in response to the wireless broadband terrestrial transmission scheme, a first preamble and a first data frame, by a first set of relay stations, towards multiple subscriber devices, substantially simultaneously; and transmitting, in response to the wireless broadband terrestrial transmission scheme, a second preamble and a second data frame by another relay station towards other subscriber devices. Wherein a coverage area of the other relay station does not substantially overlap a coverage area of any of the first set of relay stations.2008-09-04
20080212513Protocol Data Units and Header in Multihop Relay Network - The invention provides a data structure embodied in a computer readable media. The data structure is a protocol data packet (PDU) communicated in a mobile multihop network between stations. The data structure includes a relay media access header, a payload and an optional cyclical redundancy checksum for the protocol data unit; and an indication whether the PDU is a relay media access protocol data unit or not.2008-09-04
20080212514COLLISION-FREE GROUP HOPPING IN A WIRELESS COMMUNICATION SYSTEM - Techniques for supporting data transmission with little or no control overhead are described. In an aspect, data may be sent based on a hybrid scheme that utilizes a combination of group hopping for transmissions of new packets and static grouping for retransmissions of pending packets. For the hybrid scheme, a user equipment (UE) may be assigned different resource blocks in different transmission intervals based on a hopping pattern. The first transmission of new packets may be sent on resource blocks determined based on the hopping pattern. Retransmissions of each packet, if any, may be sent on the resource block used for the first transmission of the packet. The UE may perform blind decoding to recover packets sent to the UE. In another aspect, semi-static group assignment may be used, and the UE may be assigned a group of resource blocks that may change periodically or based on trigger events.2008-09-04
