Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an uplink resource scheduling method, an uplink resource scheduling apparatus, a network side device, and a terminal device.
Background
Currently, development work of a 5 th generation mobile communication system (5G) is actively underway. According to future application requirements, the 5G system needs to support a variety of service scenarios, wherein Low-Latency and high-reliability (URLLC) communication scenarios such as unmanned driving, industrial automation, and the like are receiving wide attention. Generally, URLLC data has very high burstiness and high requirement on delay, so that this type of data has very high resource scheduling priority. The existing solution proposed for the transmission of URLLC data is: when the URLLC data arrives, the 5G base station immediately schedules the URLLC data, that is, performs puncturing transmission on an enhanced Mobile Broadband (eMBB) data block in which resource allocation has been completed, so as to realize the fastest data transfer, and further meet the requirement of the URLLC data on time delay. Therefore, the downlink URLLC data can be transmitted well in the central scheduling mode.
However, in the uplink process, data is sent to the base station by each terminal, if a scheduling-free mode is adopted, collision among the data will be caused when multiple terminals send URLLC data at the same time, and in addition, if other eMBB terminals in the same BWP (Bandwidth Part) do not stop their plastic aggregation transmission, the transmitted same-frequency eMBB data will also have a great influence on the transmission of URLLC data. In order to avoid the interference problems and ensure the reliability of the URLLC data, the URLLC terminal adopts an uplink data transmission method based on the scheduling Request, which can ensure the reliability better, that is, the URLLC terminal sends an uplink data scheduling Request (Schedule Request, SR) to the 5G base station before the transmission number, and in addition, for the URLLC data, the transmission method is divided into two types, namely, periodic transmission and aperiodic transmission.
