A scheduling request method, network side device, terminal device and system, belong to the field of communications technologies. The method includes: configuring a first shared resource used for a scheduling request (SR), and sending first information to multiple terminal devices to notify of the first shared resource (101); receiving the SR on the first shared resource (102); allocating a second shared resource of uplink data to the multiple terminal devices, or allocating a dedicated resource of uplink data to at least one of the multiple terminal devices (103). The network side device includes: a configuration module, a receiving module and an allocation module. The terminal device includes: a receiving module, a request module and a sending module. The present invention avoids the waste of the uplink data resource, and improves a utilization rate of the uplink data resource and a transmission success rate of the uplink data. |

1. A device communication scheduling request method, comprising:
determining, by a network side device, terminal devices to share a resource to schedule requests (SRs) for resources, according to at least one communication factor and/or index numbers for the terminal devices; configuring, by the network side device, a shared SR resource for the determined terminal devices to send SRs to the network side device using the shared SR resource; notifying, by the network side device, the determined terminal devices of the configured shared SR resource to receive the SRs sent to the network side device using the shared SR resource; receiving, by the network side device, the SRs of the determined terminal devices from the notified configured shared SR resource; allocating, by the network side device, a shared uplink data resource used for uplink data to the determined terminal devices for which the shared SR resource is configured, or allocating, by the network device, a dedicated data resource used for uplink data to at least one determined terminal device of the determined terminal devices for which the shared SR resource is configured, responsive to the received SRs of the determined terminal devices by the network side device from the notified configured shared SR resource; allocating a scheduling request radio network temporary identifier (SR-RNTI) to the shared SR resource,
wherein, the notifying, by the network side device, sends the SR-RNTI to the determined terminal devices, andwherein the allocating, by the network side device, the shared uplink data resource, or the allocating, by the network side device, the dedicated data resource used for uplink data, allocates the shared uplink data resource used for the uplink data according to the allocated SR-RNTI, or allocates the dedicated data resource used for the uplink data according to a cell radio network temporary identifier (C-RNTI); and setting a new data indicator (NDI) to be a new data transmission, according to the allocating, by the network side device, the shared uplink data resource or the dedicated data resource used for the uplink data. |
