Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] When describing the embodiments of the present invention, some concepts used in the following description are explained first.

[0040] The random access process is mainly divided into: non-contention random access and contention random access. Among them, the contention random access process such as figure 2 As shown, it is mainly divided into four steps:

[0041] Msg1 (message 1): The terminal selects a random access resource and uses the random access resource to send the selected random access signal (for example, preamble) to the base station. After sending Msg1, the terminal calculates the identity information (ie, RA-RNTI (Random Access Radio Network Temporary Identity, Random Access Radio Network Temporary Identity)) of scheduling ...

Abstract

The invention provides a random access method, a terminal and network equipment, and relates to the technical field of communication. The random access method is applied to a terminal and comprises the following steps: acquiring configuration information of target random access; determining a first physical uplink shared channel (PUSCH) resource for sending a message I according to the configuration information; and sending a first message of target random access on the first PUSCH resource. According to the scheme, the first PUSCH resource for sending the message I in the simplified two-stepcompetitive random access is determined according to the configuration information of the simplified two-step competitive random access, and the message I is sent, so that the network communication process is perfected, and the reliability of network communication is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a random access method, terminal and network equipment. Background technique [0002] NR (New radio, new air interface) will introduce a simplified two-step contention random access process to reduce the delay of contention random access. The specific process is as follows figure 1 shown, including: [0003] Msg0 (message 0): the network side configures the UE (User Equipment, user equipment, also called terminal) with the configuration information required for simplified two-step random access, such as the transmission resources of Msg1 (message 1). [0004] Msg1 (message 1): The terminal selects a random access resource and uses the random access resource to send the selected random access signal (for example, preamble (preamble)) to the base station. At the same time, Msg1 carries the UE identifier, through which the network side can determine which UE is send...
