Method and device for distributing temporary recognition number of subdistrict wireless network

Abstract

A base station distributes C-RNTI method comprising steps: the user equipment sends the random access leader sequence to the base station; the base station sends the response message to the random access leader sequence to the user equipment, the message comprises: a distributing information of the uplink resource, a time regulating information, and an information together with the random access leader sequence identification number indicating CRNTI. The user equipment will send L3 message to the network end; the network end will send response of the L3 message to the user equipment. The present invention uses the random access leader sequence and sending sub-frame used by the user equipment and detected by the base station comparing with the traditional C-RNTI distributing method. The present invention sends the random access channel information to packet C-RNTI, thereby decreasing the indicating information bit needed by the C-RNTI distribution, decreasing the signaling burden needed by the C-RNTI distribution, optimizing the random access course, promoting the performance of the random access.

Description

technical field [0001] The invention relates to a method for distributing cell radio network temporary identification number (C-RNTI) used for asynchronous random access process in a mobile radio communication system. Background technique [0002] Now, the third generation partnership project (referred to as 3GPP) standardization organization has begun to carry out long-term evolution (LTE) of its existing system specifications. According to the current discussion about LTE, Orthogonal Frequency Division Multiplexing (OFDM) technology will be used as the downlink physical layer transmission technology in LTE, and single carrier frequency division multiple access (SC-FDMA for short) will be used as the uplink physical layer transmission technology in LTE. Layer transfer technology. [0003] A very important process in the LTE communication system is the random access process, and the random access process is divided into a synchronous random access process and an asynchronou...

Problems solved by technology

Although in this way, the user equipment can obtain the allocation of C-RNTI earlier, but because the length of the C-RNTI sequence is long, and the network end cannot obtain accurate channel quality information when sending the response of the preamble sequence to the user equipment, At this time, the C-RNTI is assigned to the user equipment, and the signaling burden is relatively large

In addition, some companies currently propose to use the L1 / L2 control channel to send the response of the random access preamble to the user equipment, although the use of the L1 / L2 control channel to transmit the response of the preamble will avoid the signaling burden required for allocating the downlink shared data channel. However, due to the heavy burden of transmitting C-RNTI, it is almost impossible to use the L1 / L2 control channel to transmit the allocation of C-RNTI
