Problems solved by technology

[0020] If after decoding the random access response message, the terminal finds that it has not been responded to, then perform random access again on the subsequent dedicated random access resource, that is, after the terminal sends the Preamble, it needs to wait for A+B+C After a period of time, it can be confirmed that the network has not responded to the Pream

Embodiment Construction

[0055] The basic idea of ​​the present invention is to determine the time required for the terminal random access failure, and according to the determined time, set an appropriate dedicated random access resource reservation period for the base station to allocate dedicated random access to the terminal during the random access process. Access resources.

[0056] The method for reserving dedicated random access resources and the implementation of the base station of the present invention will be described in detail below with reference to the accompanying drawings.

[0057] image 3 It is a schematic diagram of the process flow of the method for reservation of dedicated random access resources of the present invention, such as image 3 As shown, the method includes:

[0058] Step 301: The base station estimates the time required for the random access failure of its corresponding terminal.

[0059] Among them, the time required for the random access failure of the terminal is the ...

Abstract

The invention provides a method of specialized random access resource reservation. In the method, the required time of the terminal random access failure is estimated, and according to the required time of the terminal random access failure, the reserved period of specialized random access resources is determined; when the random access process is triggered, the base station distributes specialized random access resources for the terminal according to the reserved period. The invention simultaneously provides a base station for realizing the specialized random access resource reservation, and the method and the base station can avoid unnecessary specialized random access resource reservation and improves the utilization rate of the specialized random access resources.

Description

Technical field [0001] The present invention relates to a random access technology in a mobile communication system, in particular to a dedicated random access resource reservation method and a base station. Background technique [0002] In a mobile communication system, uplink data transmission needs to meet a unique transmission condition, that is, uplink synchronization, whose purpose is to synchronize uplink signals from different distances and different terminals to the base station or relay. Uplink synchronization can bring many benefits to the system, such as reducing signal interference between adjacent time slots, improving system performance, and simplifying the design of base station / relay receivers. Therefore, a terminal in an asynchronous state needs to establish uplink synchronization with the network through a random access process before performing uplink data transmission, and then perform uplink data transmission in an uplink synchronization manner. The random a...
