Description

Wireless communication method, terminal device and network device

The present application claims priority from PCT patent application filed by chinese patent office, application number PCT/CN2018/113724, application name "wireless communication method, terminal device and network device", at 11/2, 2018, the entire contents of which are incorporated herein by reference.

Technical Field

The embodiments of the present application relate to the field of communications, and more particularly, to a wireless communication method, a terminal device, and a network device.

Background

In the New air interface (NR), both enhanced mobile Ultra-wideband (Enhance Mobile Broadband, eMBB) and high reliability low latency communications (Ultra-Reliable and Low Latency Communication, URLLC) need to be supported. Traffic as in the industrial internet of things (Industrial Internet of Things, IIOT) may be contained in URLLC traffic. The URLLC service needs to guarantee its high reliability and low latency requirements, while the uplink shared channel (Uplink Shared Channel, UL-SCH) duration (duration) of the eMBB service is longer. When a logical channel corresponding to a URLLC service triggers a scheduling request (Scheduling Request, SR), and then the terminal device receives an Uplink scheduling resource (Uplink grant) for an ebmb service, even if buffer status report (Buffer Status Report, BSR) information corresponding to the logical channel corresponding to the URLLC service is included in a medium access control (Media Access Control, MAC) protocol data unit (Protocol Data Unit, PDU), the SR is cancelled, and due to high requirement of the URLLC service on time delay, the BSR may not be successfully reported yet, and the URLLC service is overtime. Or when the physical uplink control channel (Physical Uplink Control Channel, PUCCH) carrying the SR collides with the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), the PUSCH is prioritized, the SR cannot be reported, and the URLLC service is overtime. Therefore, in the NR system, how to determine the condition under which the SR triggered by the logical channel corresponding to the URLLC service is cancelled is a problem to be solved.

In an embodiment, if the scheduling request is triggered by the logical channel corresponding to the first service, and the priority of the first service is higher than the priority of the service transmitted by the uplink scheduling resource, or the priority of the first service is higher than the priority of the service corresponding to the BSR MAC CE carried by the uplink scheduling resource, the terminal device determines that the scheduling request triggered by the logical channel corresponding to the first service is not cancelled, and/or the terminal device receives first indication information sent by the MAC entity of the terminal device, where the first indication information is used to indicate that the transmission of the PUCCH carrying the scheduling request is preferentially performed.

It should be noted that, the first configuration information may be configured by the network device in advance. In other words, the terminal device has received the first configuration information from the network device before the terminal device cancels the scheduling request triggered by the logical channel corresponding to the first service. I.e. the terminal device receives the first configuration information sent by the network device before the terminal device performs step S210. In an embodiment, the first configuration information may be configured by the network device through an RRC message.
