Abstract

An embodiment of the invention provides a communication method and communication devices. The method comprises the steps as follows: a first communication device sends information to a second communication device at an nth sub frame, wherein the n is an integral number; and the first communication device receives feedback message of the information at an (n+k)th sub frame, wherein the k is an integral number larger than or is equal to 5. According to the communication method and the communication devices, the time series of an HARQ (hybrid automatic repeat request) is modified, so that the interval between the time when the first communication device sends the information and the time when the first communication device receives the feedback message of the information is increased, the air interface processing time delay tolerated by a system is increased, and long-distanced community coverage can be supported.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and more specifically, to a communication method, user equipment, base station, and communication equipment Background technique [0002] The Long Term Evolution (English for LongTermEvolution, English abbreviation for LTE) system requires the time alignment of the uplink signals of different user equipments (UE, Equipment) to arrive at the evolved base station (English for evolvedNodeB, English abbreviation for eNB), so as to ensure the time alignment between UEs. The orthogonality of the uplink signals between them helps to eliminate the interference in the cell. The time calibration of the uplink transmission is realized by performing timing advance (TimingAdvance in English, TA in English abbreviation) on the UE side. [0003] At present, in the process of initially accessing the LTE, the UE firstly sends an uplink Physical Random Access Channel (Physical Rando...
