Problems solved by technology

When the handover delay is exceeded, the base station still has not received the RRC reconfiguration completion message sent by the UE, and will re-perform the RRC-based handover process, resulting in the UE's user service being unable to be scheduled in time and prolonging the service delay.

Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0048] The embodiment of the present application provides an information processing method, and the information processing method is applied to the partial bandwidth BWP handover process of RRC (Radio Resource Controller, radio resource controller) in 5G NR (New Radio, new air interface). In 5G NR, on the basis of the system bandwidth, a partial bandwidth BWP (Bandwidth Part) is introduced. Each terminal (User Equipment, UE) can be configured with multiple downlink BWPs and multiple ...

Abstract

The invention discloses an information processing method and device, base station equipment and a communication system, wherein the information processing method comprises the steps: responding to a BWP switching instruction sent by a base station to a terminal, the base station sends scheduling information to the terminal on an original BWP, the base station detects whether feedback information of the terminal based on the scheduling information is received, if yes, the base station continues to send the BWP switching instruction, until the base station determines that the terminal correctly receives the BWP switching instruction. According to the invention, the base station judges whether the BWP switching instruction is correctly received by the terminal by sending the scheduling information, and if the terminal fails to receive, the BWP switching instruction can be quickly retransmitted, so that the delay influence of BWP switching on terminal service scheduling is reduced.

Description

technical field [0001] The present application relates to the technical field of communication, and more specifically relates to an information processing method, device, base station equipment and communication system. Background technique [0002] In the fifth generation mobile communication technology (the 5th generation, 5G) new radio (new radio, NR) system, on the basis of the system bandwidth, the concept of partial bandwidth (bandwidth part, BWP) is introduced. The introduction of BWP is beneficial to control the cost and power consumption of terminal equipment. Each UE (User Equipment, user terminal) can be configured with multiple downlink BWPs and multiple uplink BWPs. The base station performs BWP dynamic switching according to the UE's bandwidth requirements and service traffic to adapt to different service requirements. [0003] Among them, the BWP handover process based on RRC (Radio Resource Controller, radio resource controller) is: when the UE receives the...
