Embodiment Construction

[0075] In the embodiment of the present invention, the RN device initiates random access to the evolved base station eNB through a dedicated random access resource; the eNB determines that the device that initiates the random access is the RN device according to the dedicated random access resource used to initiate the random access. When the RN device performs random access, the eNB can determine that the device performing random access is the RN device, thereby shortening the time from power-on to working of the RN device.

[0076] Wherein, the dedicated random access resource is allocated by the eNB for the RN device.

[0077] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0078] Such as figure 2 As shown, the system for initiating random access in this embodiment of the present invention includes: RN equipment 10 and eNB 20 .

[0079] The RN device 10 is configured to initiate random ac...

Abstract

The invention relates to a wireless communication technology, in particular to a method, a system and a device for initiating random access through which eNB can determine the equipment for random access to be RN equipment when the RN equipment randomly accesses so as to shorten the time of the RN equipment from being electrified to work. The method of the embodiment comprises the following steps that: the RN equipment initiates random access to the eNB through a special random access resource, and the special random access resource is distributed to the RN equipment by the eNB; and the eNB determines the equipment for initiating random access to be the RN equipment according to the special random access resource used for initiating the random access. The method of the embodiment can shorten the time for the RN equipment from being electrified to working, and because the eNB can quite early identify that the RN equipment can first distribute resources for the RN equipment, the resource quality and the working stability of the RN equipment are ensured.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and device for initiating random access. Background technique [0002] In a mobile communication system, uplink data transmission needs to meet a unique transmission condition, that is, uplink synchronization. Its purpose is to enable uplink signals from different terminals (UEs) at different distances to arrive at the base station synchronously. [0003] Uplink synchronization can bring many benefits to the system, such as reducing signal interference between adjacent time slots, improving system performance, and simplifying base station design. Therefore, before sending uplink data, a terminal in an asynchronous state needs to perform uplink synchronization with the network side through a random access process, and then perform subsequent transmission in a synchronous manner. [0004] In LTE (Long Term Evolution, Long Term Evolution), the basic me...
