Abstract

The application discloses a remote device, a base station, a random access method, a storage medium and a program product, belonging to the technical field of communication. The remote device includes a radio frequency device and a baseband device, and the baseband device is used to process part or all of the physical layer protocol on the data of the UE, and is used to respond to the random access preamble sent by the UE. In this application, after receiving the random access preamble of the UE, the remote device can directly respond to the random access preamble through the baseband device without sending it to the centralized control device for the centralized control device to respond, so that The transmission delay between the remote device and the centralized control device can be avoided, and the random access response can be returned to the UE in time.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a remote device for a base station, a base station and a random access method. Background technique [0002] A communication system usually includes a base station, which is used to provide services such as radio resource scheduling, radio resource management, mobility, handover, and admission control for user equipment (UE) within its coverage area, and the base station is also responsible for selecting services for The core network equipment served by the UE. Wherein, the base station may provide a random access service for the UE. That is, when the UE tries to access the mobile communication network, the base station can receive the random access preamble sent by the UE, and return a random access response to the UE, so that the UE can successfully access the mobile communication network based on the random access response. [0003] In order to facilitat...
