摘要: A wireless communication system provides for a random access channel (RACH) procedure user equipment (UE) to request an uplink channel. From physical layer perspective, evolved Base Station (eNB) responds with preamble and response (RAR) of fixed length message, such as 21 bits or 20 reserved bit future extensions. In answer need that exists RAR accommodate variations in bandwidth, approach encoding truncated resource block (RB) assignment the manner which UE can interpret without loss information. Thereby, needs achieving RACH procedures existing resources be realized.
