Title: METHOD, DEVICE AND SYSTEM FOR SENDING PHYSICAL RANDOM ACCESS CHANNEL (PRACH)
Abstract:
Disclosed are a method, device and system for sending a PRACH, which provide an implementation of transmitting the PRACH on a carrier of a frequency spectrum resource. The method comprises: an access network device sending first indication signalling within a first time period, wherein the first indication signalling comprises first PRACH resource indication information, the first PRACH resource indication information is used for indicating time domain position information about a first PRACH resource within a second time period, the first PRACH resource is configured for terminal devices under a cell served by the access network device, and the first indication signalling is physical layer signalling; and the access network device detecting a random access preamble sequence on the first PRACH resource within the second time period.
