Embodiment Construction

[0113] Hereinafter, some terms used in this application are explained to facilitate the understanding of those skilled in the art.

[0114] 1) Terminal equipment, which can be a wireless terminal or a wired terminal. The wireless terminal can be a device that provides voice and / or data connectivity to the user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem equipment. The wireless terminal can communicate with one or more core networks via a radio access network (RAN), and the wireless terminal can be a mobile terminal, such as a mobile phone (or called a "cellular" phone) and a computer with a mobile terminal , for example, may be portable, pocket, handheld, computer built-in, or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network. For example, a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loo...

Abstract

The present invention provides a message sending method and device. The method includes the following steps that: a random access request sent by a terminal device on a physical random access channel(PRACH) resource is received, wherein the PRACH resource is indicated by remaining minimum system information (RMSI); a resource for transmitting the information of a random access response (RAR) is determined according to preset corresponding relationships, wherein the corresponding relationships comprise a corresponding relationship between any one of the plurality of pieces of RMSI and PRACH configuration information; and the control information of the RAR and / or the data information of the RAR is sent on the resource to the terminal device. With the message sending method and device provided by the embodiments of the present invention adopted, the communication performance of a communication system can be improved.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a method and device for sending messages. Background technique [0002] Usually, in the process of terminal equipment accessing the carrier, it needs to go through the process of cell search, acquisition of cell system information and random access. Among them, during the cell search process, it is necessary to blindly detect the synchronization signal block SS block. The SS block includes the synchronization signal and the master information block (Master Information Block; MIB for short). Secondly, the UE will receive the system information sent by the base station, such as the remaining minimum System information (remaining minimum system information; RMSI) and other system information (Other system information; OSI) are finally connected to the carrier through a random access process. However, the random access performance of the existing communication system still...
