Embodiment Construction

[0014] The inventive concepts and features are described here in terms of a Long Term Evolution (LTE) system or other so-called 4G communication system as an enhancement to current 3GPP technology. However, these details are not limitations of the various features described herein, which may be applied to other types of mobile and / or wireless communication systems and methods.

[0015] Hereinafter, the term "mobile terminal" will be used to refer to various types of user equipment, such as mobile communication terminals, user equipment (UE), mobile equipment (ME), and other equipment supporting various types of wireless communication technologies.

[0016] Embodiments of the present invention relate to transmitting and receiving data between a base station (e.g., Node B, eNB, access point, etc.) and a mobile station (e.g., mobile terminal, UE, user equipment, etc.) in a Long Term Evolution (LTE) system . Since the reception time of the downlink channel is determined according...

Abstract

A method of performing a random access channel (RACH) procedure between a mobile terminal and a network includes the steps of detecting whether a random access response (RAR) is received from the network within a certain time period, the RAR including information about a random access channel (RACH) preamble transmitted to the network; and if the RAR is not received within the certain time period or if the information about the transmitted RACH preamble included in the RAR does not match the transmitted RACH preamble, performing a first procedure to detect failures in the RACH procedure; and if the RAR is received within the certain time period and if the information about the transmitted RACH preamble included in the RAR matches the transmitted RACH preamble, performing a second procedure to detect failures in the RACH procedure.

Description

technical field [0001] The present invention relates to an apparatus and method for sending MAC PDU to handle buffer status report (BSR: buffer status report) priority for CCCH transmission. Background technique [0002] In the prior art, a buffer status report (BSR) is sent from the mobile terminal in a specific manner. However, the prior art does not adequately address how to transmit buffer status reports (BSRs) faster and more efficiently, and thus does not provide a suitable solution. Contents of the invention [0003] The inventors have recognized at least the above-mentioned deficiencies of the prior art. Based on this recognition, the various features described below have been conceived for sending and receiving data between base stations and mobile terminals in a Long Term Evolution (LTE) system. Specifically, in order to transmit data stored in the buffer of the mobile terminal, the mobile terminal transmits its buffer status information (ie, buffer status repo...
