Abstract
A method and apparatus for multiplexing communication resources to multiple users in a communication system is provided. A generic time-frequency (T-F) mapping pattern (TFPgeneric) and a set of orthogonal T-F mapping patterns (TFPs) comprising TFPgeneric is generated. In each transmission time interval (TTI), the set of TFPs is cyclically offset by a random variable and the offset TFPs are allocated to one or more users and/or traffic channels.
Claims17
Method for multiplexing one or more users and/or traffic channels to one or more communication resources in a time-frequency divided communication system, wherein the multiplexing does not require communication resource planning, and is represented by a set of time-frequency (T-F) mapping patterns (TFPs), the method comprising:
- generating, by the time-frequency divided communication system, a generic TFP (TFPgeneric),
- generating, by the time-frequency divided communication system, a set of orthogonal TFPs from said TFPgeneric;
- performing, by the time-frequency divided communication system, a pseudo-random variable cyclic offsetting of said set of orthogonal TFPs in each transmission time interval (TTI);
- changing said pseudo-random cyclic offset for each TTI, according to a cell-specific multi-level pseudo-random sequence;
- and
- allocating, by the time-frequency divided communication system, the pseudo-randomly cyclically offset orthogonal TFPs to the one or more users and/or traffic channels in each TTI for multiplexing the one or more users and/or traffic channels to the one or more communication resources in the time-frequency divided communication system.
