Problems solved by technology

[0004] However, the process for the terminal device to modify the logical channel configuration of the logical channel in the RRC configuration (this process is also called the RRC reconfiguration process) is relatively cumbersome, which may cause a backlog of buffers in the logical channel
At the same time, modifying the logical channel configuration of the logical channel during the RRC reconfiguration process will generate more RRC signaling, which affects the performance of the terminal device

Embodiment Construction

[0097] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0098] In the following description, for purposes of illustration rather than limitation, specific details such as specific system architectures, interfaces, and techniques are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0099] In addition, the terms "comprising" and "having" and any variat...

Abstract

Embodiments of the invention provide a method, devices and a system for scheduling a logical channel, relate to the field of communication, and can be used for dynamically sending logical channel scheduling indication information to a terminal device, so that the configuration of the logic channel meets the requirements of real-time scheduling, and the transmission performance of the terminal device is improved while the RRC signaling overhead needed for the configuration of the logic channel is saved. The method for scheduling the logical channel comprises the steps that the terminal device receives control information sent by a network device, wherein the control information comprises the logical channel scheduling indication information, and the logical channel scheduling indication information is any one of an indication of independently calling resources by the logical channel, an indication of a prioritized bit rate (PBR) of logical channel scheduling and an indication of a logical channel priority (LCP); and the terminal device acquires uplink scheduling resources for sending logical channel data according to the logical channel scheduling indication information.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a logical channel scheduling method, device and system. Background technique [0002] The rapid development of the 5th Generation mobile communication technology (5G) has made mobile communication have a huge impact on people's life and work. 5G application scenarios usually include: enhanced Mobile Broadband (eMBB), massive Machine Type Communications (mMTC) and Ultra-Reliable and Low Latency Communications (URLLC). Since the URLLC service has high requirements on service delay and service reliability, how to ensure the service requirements of other logical channels on the premise of ensuring the URLLC service requirements has become an urgent problem to be solved. [0003] Before an existing terminal device sends uplink data to a network device, it first needs to receive an uplink scheduling resource sent by the network device. Since the total amount o...
