Problems solved by technology

However, there is currently no specific processing mechanism for notifying the terminal of the allocation result of the uplink resource, so that the terminal cannot know the location of the uplink resource allocated for its Msg3, and the processing is ambiguous and unclear, which cannot guarantee the normal operation of the system

Embodiment Construction

[0039] In the present invention, the network sends a random access response carrying a resource allocation position indication in a set format to the terminal, and the terminal determines the uplink resource position through the resource allocation position indication according to the set format, and performs uplink transmission on the uplink resource position.

[0040] Fig. 4 is a flow chart of random access with contention in the present invention, as shown in Fig. 4, the processing procedure of random access with contention includes the following steps:

[0041] Step 401 is the same as step 201.

[0042] Step 402: After receiving the random access preamble, the network dynamically allocates uplink resources for the terminal, and sends a random access response, ie, Msg2, to the terminal in the downlink direction. Msg2 carries a resource allocation location indication in a set format. The sending time of Msg2 is dynamically scheduled by the network. Msg2 for multiple termin...

Abstract

The present invention provides a method for indicating the resource allocation position in a random access process. Network transmits a random access response carrying resource allocation position indication with preset format to a terminal. The terminal confirms the uplink resource position according to the preset format through the resource allocation position indication. Furthermore an uplink transmission is executed on the uplink resource position. The ambiguity of resource allocation can be effectively eliminated and the normal operation of system is guaranteed. Additionally the invention provides a plurality of realizing modes for the flexible selection in the practical application, wherein some processing modes can effectively reduce the signaling spending and saves the system resource.

Description

technical field [0001] The present invention relates to random access technology, in particular to a method, system and device for indicating resource allocation positions in the random access process. Background technique [0002] In the Long Term Evolution (LTE, Long Term Evolution) system, the frame structure is divided into two types: frame structure type 1 (Frame structure type 1) and frame structure type 2 (Frame structure type 2). [0003] There are two modes of frequency division duplex (FDD, Frequency Division Duplex) and time division duplex (TDD, Time Division Duplex) in frame structure type 1, and its frame structure is shown in Figure 1A: the length of a radio frame (radio frame) is 10ms; the radio frame includes 10 subframes (subframe), and the length of each subframe is 1ms; each subframe includes two slots (slot), and the length of one slot is 0.5ms. One Transmission Time Interval (TTI, Transmission Time Interval) corresponds to one subframe. [0004] There...
