Title: COMMUNICATION METHOD UTILIZING RANDOM ACCESS, TERMINAL, AND BASE STATION
Abstract:
The embodiment of the invention provides a communication method utilizing random access and comprising: a terminal receives a random access pilot message transmitted by a base station; the terminal transmits, according to the random access pilot message and to the base station, a random access response transmitted by the base station and received by the terminal prior to performing random access, wherein the random access response comprises an uplink asynchronous hybrid automatic repeat request (HARQ) process identifier; and the uplink asynchronous HARQ process identifier is used by the terminal to transmit, to the base station, uplink data. In comparison to the prior art, the communication method provided by the embodiment of the invention can ensure timely transmission of uplink data, and effectively increase reliability of uplink data transmission.
