Abstract
Disclosed herein are an active resource unit detector and a method of use thereof. An embodiment method of detecting active resource units among a plurality of potential resource units includes receiving an aggregate signal containing active pilots transmitted over the active resource units via random access transmissions. The active pilots are then detected and respectively associated with the active resource units according to a pilot-to-resource unit mapping.
Claims24
A method of detecting resource units in a random access transmission system, the method comprising:
- receiving an aggregate signal containing a sum of active pilots transmitted over a shared time-frequency resource via random access transmissions by active user equipments;
- detecting the active pilots from the received aggregate signal;
- and
- respectively associating the active pilots with the resource units according to a pilot-to-resource unit mapping.
A communications controller for detecting resource units in a random access transmission system, the communications controller comprising:
- a receiver configured to receive an aggregate signal containing a sum of active pilots transmitted over a shared time-frequency resource via random access transmissions by active user equipments;
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the receiver and the memory storage, wherein the one or more processors execute the instructions to:
- detect the active pilots from the received aggregate signal;
- and
- respectively associate the active pilots with the resource units according to a pilot-to-resource unit mapping.
