Abstract

The embodiment of the present invention discloses a method for transmitting a scheduling request, a method for processing the scheduling request, and a related device. The method for transmitting thescheduling request includes the steps: triggering the first SR if a first logic channel of a terminal device has to-be-transmitted data, and determining whether there is a first scheduling resource allocation corresponding to the first logic channel according to first indication information, wherein the first indication information includes a first mapping relation, the first mapping relation isused to indicate the corresponding relation between the logic channel of the terminal device and the scheduling resource allocation, and the first scheduling resource configuration includes a first uplink control channel resource corresponding to the first logic channel; and transmitting a first SR to the access network device through the first uplink control channel resource if the first logic channel has the corresponding first scheduling resource allocation. According to the embodiment of the present invention, the scheduling request can be sent to the access network device based on the logic channel, so that the access network device can reasonably allocate the uplink resource for the logic channel according to the service type of the logic channel.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for sending a dispatch request, a method for processing the dispatch request and related equipment. Background technique [0002] In a wireless cellular network (for example, long term evolution (LTE)), a terminal device needs to establish a radio resource control (radio resource control, RRC) connection with an access network device before sending uplink data, and then The resource control connection state sends a scheduling request (scheduling request, SR) to the access network device. If the access network device allows the terminal device to send uplink data, it will send a scheduling instruction to the terminal device. The uplink data is sent to the access network device on the indicated time-frequency resource, and such a transmission process may be called scheduled transmission. However, scheduled transmission has the following disadvantages: the t...
