Technical Field
The present invention relates to the field of communications technologies, and in particular, to an uplink communication control method, an uplink communication control apparatus, and a network side device.
Background
Currently, development work of a 5 th generation mobile communication system (5G) is actively underway. According to the future application requirements, the 5G system needs to support various service scenarios, wherein the communication scenarios with Low time delay and high reliability (URLLC), such as unmanned driving, industrial automation, etc., 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 downlink transmission of URLLC data is: when URLLC data arrives, a 5G base station (gNB) immediately schedules the URLLC data, namely, the eMBB data block of the enhanced Mobile Broadband (eMBB) which finishes resource allocation is subjected to punching transmission, so that the fastest data transmission is realized, and the requirement of the URLLC data on time delay is further met. Therefore, the downlink URLLC data can be transmitted well in the central scheduling mode.
In one network, there may be a terminal supporting only the URLLC service and a terminal supporting only the eMBB service, or there may be a terminal supporting both services. When the URLLC data is cached in the terminal, the UE (User Equipment) needs to apply for resources to the gNB, and the gNB may allocate resources required for URLLC data transmission to the URLLC terminal, where the required resources may be resources that the gNB allocates to a plurality of terminals transmitting the eMBB service in advance, and considering the low delay and high reliability of the URLLC service, how to make the MCS (Modulation and Coding Scheme) transmission mode of the URLLC data and the transmission power thereof meet the delay requirement thereof becomes a technical problem to be solved urgently.
