摘要： Detecting physical random access channel (RACH) preambles is accomplished by computing a correlation power profile based on received RACH preambles, where the correlation power profile values may be sorted. A weight factor is computed for each of the correlation power profile values based on a normalized RACH detection threshold. Outlier peaks of the correlation power profile values are selected based on the weight factor. The outlier peaks to the first set of RACH signatures are mapped in order to identify a user equipment (UE) that is associated with one of the received RACH preambles. Network traffic is then controlled for network communications associated with the identified UE.

摘要： The method includes generating a preamble sequence at a transmitter, where the transmitter is capable of generating a first type of preamble sequence and a second type of preamble sequence. The transmitter transmits a request message to a receiver to request network resources, where the request message including the preamble sequence. The transmitter receives a feedback message from the receiver. The transmitter controls the network data traffic based on the feedback message. The method further includes receiving, a receiver, a signal from the transmitter, the signal including the preamble sequence. The receiver detects the preamble sequence within the signal, where the receiver is capable of detecting a first type of preamble sequence and a second type of preamble sequence. The receiver identifies a request message within the signal based on the detected preamble sequence, and controls the network data traffic based on the identified request message.
