Random access message transmission using multiple symbols
A user equipment (UE) may transmit a random access message to a wireless node using multiple symbols. The random access message may include repetitions of a random access sequence weighted by a spreading code. For example, a random access sequence may be weighted using different elements of the spreading code, where a first repetition may be weighted with a first element and a second repetition may be weighted using a second element. The weighted random access signals may be spread over multiple symbols and transmitted to the wireless node as the random access message. In some cases, a spreading code may include values of one and negative one, may be based on rows of a Hadamard matrix, or may correspond to a number of symbols used to transmit the random access message.
