Scheduling method and apparatus for combined code division multiplexing and time division multiplexing |
摘要 |
A combined CDM/TDM (code division multiplexing/time division multiplexing) transmitter and method are provided which employ fractional slot assignment by assigning fractional CDM channel gains to multiple slots for at least one packet with a goal that a sum of fractional CDM gains assigned each packet over a scheduling period meet a required threshold. In some embodiments, the transmitter is adapted to determine which users to transmit during a given slot, and to determine fractional CDM channel gains using an optimization of fractional CDM channel gain and user assignment which maximizes a number of users each of which is assigned a respective group of one or more slots with fractional CDM channel gains which sum to the required threshold for the user.
