Abstract

The invention provides a method for sending an SR (scheduling request). The method comprises the following steps that access network equipment sends SR configuration to a terminal device, wherein theSR configuration comprises SR parameters corresponding to a plurality of wireless physical layer parameters Numerology; and when to-be-sent uplink data exist, the terminal device selects one SR parameter corresponding to an LCH (logical channel) where the uplink data are located according to a preset strategy, and sends the SR on SR resource corresponding to the selected SR parameter to request for uplink authorization. Further, the terminal device requests for uplink authorization in combination with the LCH in the SR configuration and / or maximal SR sending times of the terminal device.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for sending a scheduling request in a wireless network. Background technique [0002] In a Long Term Evolution (LTE) system, if a terminal device has no uplink data to send, the base station does not need to allocate uplink resources to the terminal device, so as to save system resource usage. When the terminal device needs to send uplink data to the base station, the terminal device needs to request the base station to allocate uplink resources for the terminal device to send uplink data. To this end, LTE provides an uplink scheduling request (Scheduling Request, SR) mechanism. Specifically, the base station performs media access control layer (media access control, MAC) configuration on the terminal equipment it serves, including SR configuration, which is used to configure the resources used by the terminal equipment to send SR. As described ...
