Abstract

The embodiment of the invention provides a method and a terminal for processing random access. The method comprises the steps that: the terminal triggers primary random access through a media access control (MAC) and successfully accesses network equipment; when a scheduling request (SR) is triggered, the terminal judges whether to trigger secondary random access; if not, the terminal does not execute the random access; the terminal receives an RS-related parameter carrying radio resource control (RRC) reconfiguration message sent by the network equipment; and the terminal determines physicaluplink control channel (PUCCH) resources according to the SR-related parameters and sends the SR by using the PUCCH resources. When the method and the terminal for processing the random access are used in the embodiment of the invention, whether to trigger the primary random access is judged after the primary random access succeeds, the secondary random access is not required to be triggered, theSR is sent through the effective PUCCH resources, so that the triggering time of the random access are greatly reduced. Thus, the access performance of the network system is improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a random access processing method and terminal. Background technique [0002] The Long Term Evolution (abbreviated as: LTE) system takes Orthogonal Frequency Division Multiplexing (abbreviated as: OFDM) as the core and adopts multiple-input multiple-output (Multiple-Input Multiple-Output, abbreviated For: MIMO) and other technologies, at the same time, in order to reduce user delay, the network flattening strategy is also adopted, which greatly improves the network performance. [0003] There are random access procedures triggered by various factors in the LTE system, including a random access procedure triggered by Media Access Control (Media Access Control, MAC for short). The scenario corresponding to the random access process triggered by the MAC is: when a scheduling request (Scheduling Request, referred to as: SR) is triggered, and the Physical Uplink...
