Abstract:
A method for assigning resources to FS and FNS users, for example, in an OFDM wireless communication system 100, including assigning a first frequency resource to at least one FS user during a time interval, wherein the first frequency resource includes at least two near contiguous sub-carriers, and assigning a second frequency resource to at least one FNS user during the same time interval, the second frequency resource includes for each FNS user at least two non-contiguous sub-carriers, wherein the first and second frequency resources are part of a common frequency channel.
Abstract:
A method of synchronizing a fixed access unit (16) into a time division multiple access (TDMA) system (10). The method includes the steps of receiving a timing advance channel time slot (86) at the fixed access unit (16), sending a message advanced in time by an offset value over the time slot (88), receiving an acknowledgment from the TDMA system (10) that the message was received, and advancing a subsequently transmitted communication based on the offset value.
Abstract:
The method for transmitting a communication signal comprising a plurality of units of information includes transmitting the plurality of units of information via a predetermined number of channel resources; determining a number of the plurality of units remaining in at least a portion of the communication signal (110); based on the predetermined number of channel resources, adjusting the number of the plurality of units remaining to produce an adjusted number of units remaining (112); and transmitting the adjusted number of units remaining to the wireless communication system (114).
Abstract:
The present invention encompasses a method and apparatus for efficiently communicating complex resource allocations from a central access point or base unit (14) to a mobile unit (10) requesting service. The base unit (14) allocates these resources amongst several competing mobile units (10-12) performing a variety of applications. As such, it is often desirable to generate a complex schedule to achieve the optimum assignment providing the highest quality of service to mobile units (10-12). By communicating the complex schedule of uplink resources in one downlink transfer, the mobile unit (10) is free to transmit its data on the uplink without simultaneously receiving the downlink, reducing its complexity significantly.
