Abstract
This application provides a scheduling request transmission method and an apparatus. The method includes: configuring, by a network device for a terminal device, a scheduling request (SR) resource carried on an uplink control channel; configuring, by the network device, a mapping relationship between the SR resource and a plurality of available uplink beam pairs for the terminal device; and receiving, by the network device, a scheduling request sent by the terminal device by using the plurality of uplink beam pairs and the corresponding SR resource. According to the scheduling request transmission method and the apparatus that are provided in this application, an SR is sent in a multi-beam communication scenario.
Claims13
A scheduling request transmission method comprising:
- configuring, by a network device for a terminal device, scheduling request (SR) resources carried on an uplink control channel;
- when there are a plurality of SR resources, configuring, by the network device, a mapping relationship between the SR resources and a plurality of available uplink beam pairs for the terminal device by mapping the plurality of SR resources to the plurality of uplink beam pairs, and notifying the terminal device of the mapping relationship between the plurality of SR resources and the plurality of uplink beam pairs;
- and
- receiving, by the network device, a scheduling request sent by the terminal device by using the plurality of uplink beam pairs and a corresponding SR resource.
A scheduling request transmission method comprising:
- obtaining, by a terminal device, a scheduling request (SR) resource configured by a network device for the terminal device carried on an uplink control channel;
- and
- obtaining, by the terminal device, a mapping relationship between the SR resource and a plurality of uplink beam pairs configured by the network device for the terminal device.
A network device comprising:
- a processor adapted to:
