Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for sending an uplink occupation indication signaling, a method and an apparatus for receiving an uplink occupation indication signaling, and a communication device.
Background
Currently, the development of the 5 th generation mobile communication system (5G) is under way. According to future application requirements, the 5G system needs to support various service scenarios, wherein communication scenarios such as unmanned driving, industrial automation and the like with high reliability and low time delay (Ultra-reliable and Low Latency Communications, URLLC) are receiving a great deal of attention. Generally, the URLLC data has extremely high burstiness and has high requirement on time delay, so that the data has extremely high resource scheduling priority. The solutions proposed at present for downlink transmission of URLLC data are: when the URLLC data arrives, the 5G base station (gNB) immediately schedules the URLLC data, namely, performs punching transmission in the enhanced mobile broadband (Enhance Mobile Broadband, eMBB) data block with the completed resource configuration, so as to realize the fastest data transmission, further meet the requirement of the URLLC data on time delay, and the Down (DL) URLLC data can be well transmitted in the central scheduling mode.
However, in the uplink process, data is sent to the base station by each terminal, if a scheduling-free manner is adopted, collision between data will be caused by multiple terminals sending URLLC data at the same time, and if other eMBB terminals in the same BWP (Bandwidth unit) do not stop their data transmission, the transmitting co-frequency eMBB data will also have a great influence on the transmission of URLLC data. In order to avoid the foregoing interference problems and ensure reliability of the ullc data, the ullc terminal adopts an uplink data transmission manner based on a scheduling Request, that is, as shown in fig. 1, the ullc terminal sends an uplink data Scheduling Request (SR) to the 5G base station before sending the data, the base station immediately configures uplink data transmission resources for the ullc terminal after receiving the Request, and loads the resource configuration information in an uplink occupation indication (Uplink Preemption Indication, UL-PI) to send to all terminals in the cell, where the uplink occupation indication includes a time-frequency position where the uplink resources configured by the base station for the ullc terminal are located, the ullc terminal receives the UL-PI to obtain the uplink resources configured by the base station for the ullc terminal, so that uplink transmission of the ullc data is performed on the corresponding resources, and other eMBB terminals receive the UL-PI and stop transmission of the data on the corresponding resource positions, so as to avoid interference to the uplink ullc data.
In the current UL-PI transmission scheme, after the ullc terminal sends an SR at a certain Mini-slot, the base station feeds back a UL-PI corresponding to the SR at a certain subsequent Mini-slot, so that in order to avoid interference of other eMBB to the ullc terminal, all eMBB terminals in a cell (in the same BWP as the ullc terminal) need to detect the UL-PI at each Mini-slot, so as to stop data transmission on the uplink resource allocated to the ullc terminal by the base station, and obviously, this way brings huge power consumption for the eMBB terminal.
