Abstract
Embodiments of the present disclosure provide a scheduling method and a base station. In a cell handover process, a target base station serving a target cell receives a random access request from a terminal, sends a random access response to the terminal according to the random access request, and proactively sends an uplink grant to the terminal after sending the random access response and prior to receiving a handover complete command from the terminal. By proactively sending the uplink grant, the target base station can perform uplink scheduling for UE before cell handover is completed, so as to reduce an uplink transmission latency caused by the cell handover.
Claims18
A method, comprising:
- receiving, by a terminal, a handover command from a source cell, wherein the handover command notifies the terminal of a handover from the source cell to a target cell;
- sending, by the terminal, a random access request to a base station serving the target cell;
- receiving, by the terminal, a random access response from the base station;
- and
- sending, by the terminal to the base station, a handover complete command to the base station, wherein after receiving the random access response and prior to sending the handover complete command, the terminal receives at least one uplink grant from the base station without sending a scheduling request (SR) and a buffer status report (BSR) for requesting the at least one uplink grant.
A device, comprising a processor and a memory that stores a program, which when executed by the processor, causes the processor to perform:
- receiving a handover command from a source cell, wherein the handover command notifies the device of a handover from the source cell to a target cell;
- sending a random access request to a base station serving the target cell;
- receiving a random access response from the base station;
- sending, to the base station, a handover complete command to the base station, wherein after receiving the random access response and prior to sending the handover complete command, the device receives at least one uplink grant from the base station without sending a scheduling request (SR) and a buffer status report (BSR) for requesting the at least one uplink grant.
A device, applied to a base station for serving a target cell to which a terminal is handed over, the device comprising a processor and a memory that stores a program, which when executed by the processor, causes the processor to perform operations, the operations comprising:
- receiving a random access request from a terminal;
- sending a random access response to the terminal according to the random access request;
- and
- after sending the random access response and prior to receiving a handover complete command from the terminal, proactively sending at least one uplink grant to the terminal without receiving, from the terminal, a scheduling request (SR) and a buffer status report (BSR) for requesting the at least one uplink grant.
