RANDOM ACCESS CHANNEL DESIGN IN MACHINE TYPE COMMUNICATIONS

摘要

A method for a random access channel design in machine type communications comprises: sending a contentious access request of a machine to a cellular device acting as a machine gateway, and receiving from a network node a contentious access response comprising a random access preamble sequence allocated by the network node for a non-contentious access transmission from the machine to the machine gateway. According to exemplary embodiments, the random access preamble sequence may be allocated based at least in part on a timing advance parameter of the cellular device according to a predefined rule.
