Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring uplink multiplexing transmission power, a method and an apparatus for transmitting uplink multiplexing data, and a communication 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 communication scenarios with high reliability and Low Latency (URLLC) 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 solution proposed at present for the transmission of downlink URLLC data is: when the URLLC data arrives, the 5G base station immediately schedules the URLLC data, that is, performs puncturing transmission in 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. However, in uplink transmission, there is a resource contention condition between multiple UEs (User equipments, User terminals), and how to ensure effective transmission of URLLC data is under discussion.
At present, two solutions are mainly proposed for effective transmission of uplink URLLC data, which are respectively two modes of scheduling (GB) -Based transmission and scheduling Free (GF) transmission. In this GB manner, the URLLC terminal needs to send a Scheduling Request (SR) to the base station before transmitting data, and after receiving the SR, the base station feeds back a Downlink Control Information (DCI) for indicating uplink transmission to the terminal, and after correctly demodulating the DCI, the URLLC terminal sends URLLC data at the uplink time-frequency position allocated by the base station. The method has the obvious defects that the duration of the process is long, the transmission delay requirement of the URLLC is difficult to meet, the probability of data errors is increased through multiple signaling or data transmission processes (SR, feedback and data), and the stability is difficult to guarantee. Compared with the prior art, the GF mode is more reasonable, and the UE adopting the GF mode does not need to send an SR to the base station before uplink transmission and wait for the resource indication of uplink scheduling of the base station, but the UE automatically selects the time-frequency resource reserved by the base station for the UE to send data. However, if too many uplink resources are reserved and there is no corresponding URLLC terminal to use, it will cause resource waste, and for this situation, the current technical discussion of 3GPP (3rd Generation Partnership Project) refers to allowing the uplink resources of eMBB to overlap with GF resources, as shown in fig. 1. However, obviously, when the eMBB terminal transmits on the overlapped resources, interference will be caused to URLLC data, and when the current power control scheme is adopted to reduce the interference, only the same low transmit power can be used by the physical downlink shared channel in the whole frame, and the URLLC data only occupies a few symbols when the URLLC and the eMBB are multiplexed in the uplink, and thus the URLLC data only plays a good role.

And the first class of terminals determine time-frequency resources which are possibly used when the high-reliability low-delay data are transmitted according to the time-frequency position information, and transmit the uplink data according to a plurality of transmission powers under the condition that the time-frequency resources occupied by the uplink data and the uplink scheduling-free resources are overlapped. By adopting the technical scheme of the invention, on one hand, the interference to high-reliability low-delay data is reduced; on the other hand, effective transmission of the first-class terminal data is ensured, and the resource utilization rate is improved.

a sending module 804, configured to send uplink data by using a first transmission power in a non-overlapping area; and transmitting uplink data using the second transmission power in the overlapping area.
In this embodiment, a time-frequency resource (uplink scheduling-free resource) that may be used when the high-reliability low-latency data is sent is determined according to the time-frequency resource location information, and an area where the time-frequency resource occupied by the eMBB terminal for sending the uplink data overlaps with the uplink scheduling-free resource is further determined. And sending uplink data by using normal power in a non-overlapping area to ensure effective transmission of eMBB data, and sending uplink data by using low power on scheduling-free resources which are possibly unused by URLLC in an overlapping area to improve data transmission quantity and improve resource utilization rate.

(1) the base station configures uplink scheduling-free resources for the URLLC terminal, so that the URLLC can self-select the scheduling-free resources reserved for the URLLC terminal when data is to be transmitted, and the base station sends the time-frequency position information of the uplink scheduling-free resources to the eMBB terminal.
(2) The base station configures two transmission powers, such as a first transmission power (normal power) and a second transmission power (low power), for the eMB terminal in the same independent decoding resource region (i.e., a TTI, such as a subframe or a slot), and transmits the two transmission powers to the eMB terminal.
(3) The eMB B terminal receives time frequency position information and two kinds of sending power of the uplink scheduling-free resource sent by the base station terminal.
(4) The eMBB terminal selects the transmission power to transmit data, as shown in fig. 9, the second transmission power (low power) is used in the region where the time-frequency resource occupied by the eMBB for transmitting the uplink data and the uplink scheduling-free resource overlap, and the first transmission power (normal power) is used in the non-overlapping region.
The invention can ensure the effective transmission of eMBB data in a non-overlapping area, and can also carry out low-power data transmission on scheduling-free resources unused by URLLC, thereby improving the data transmission quantity and the resource utilization rate (namely, when the URLLC is not used, the eMBB can transmit the data at low power, and the scheduling-free resources are not completely idle).
