Problems solved by technology

However, for the same-slot scheduling, the scheduled PDSCH and the scheduled PDCCH (physical downlink control channel, physical downlink control channel) are located in the same time slot, then the user equipment needs to create a buffer in advance to reserve for the PDSCH, thereby result in energy loss and a reduction in processing speed

Embodiment 1

[0028] see figure 1 , figure 1This is a schematic flowchart of an energy saving method based on extension of downlink control information disclosed in an embodiment of the present invention. Wherein, the energy saving based on the extension of downlink control information can be applied to a communication system, and the application of the energy saving method based on the extension of downlink control information is not limited in this embodiment of the present invention. like figure 1 As shown, the energy saving method based on downlink control information extension may include the following operations:

[0029] 101. Detect the physical downlink control channel scheduled by the downlink control information in the unit time slot.

[0030] As for the time slot, it can be known in the prior art that the basic time unit of downlink resource scheduling in NR is a time slot (slot). Generally speaking, a time slot may consist of 14 OFDM symbols in time. The network device trans...

Embodiment 2

[0040] see image 3 , image 3 This is a schematic diagram of an energy saving system based on downlink control information extension disclosed in an embodiment of the present invention. like image 3 As shown, the energy-saving system based on downlink control information extension includes:

[0041] The detection module 1 is used for detecting the physical downlink control channel scheduled by the downlink control information in the unit time slot. As for the time slot, it can be known in the prior art that the basic time unit of downlink resource scheduling in NR is a time slot (slot). Generally speaking, a time slot may consist of 14 OFDM symbols in time. The network device transmits the physical downlink shared channel PDSCH and the physical downlink control channel PDCCH for the terminal device. Since the DCI carried by the PDCCH includes relevant information required to receive the PDSCH, the relevant information may be, for example, the PDSCH time-frequency resourc...

Embodiment 3

[0049] see Figure 4 , Figure 4 A schematic flowchart of a method for operating a terminal device disclosed in an embodiment of the present invention. like Figure 4 As shown, the method for operating a terminal device includes:

[0050] 201. Receive downlink control information from a base station, where the downlink control information includes a physical downlink control channel scheduled by detecting the downlink control information in a unit time slot, and invokes multiple physical downlink shared channels through the physical downlink control channel. As for the time slot, it can be known in the prior art that the basic time unit of downlink resource scheduling in NR is a time slot (slot). Generally speaking, a time slot may consist of 14 OFDM symbols in time. The network device transmits the physical downlink shared channel PDSCH and the physical downlink control channel PDCCH for the terminal device. Since the DCI carried by the PDCCH includes relevant information...

Abstract

The invention discloses an energy-saving method based on downlink control information expansion, which includes: detecting a physical downlink control channel scheduled by the downlink control information in a unit time slot; calling multiple physical downlink control channels through the physical downlink control channel A shared channel; execute the physical downlink control channel and multiple physical downlink shared channels respectively; wherein, the execution time slot of the physical downlink control channel is different from the execution time slot of the multiple physical downlink shared channels. The invention also discloses an energy-saving system based on downlink control information expansion. The method and system disclosed in the invention can reduce the energy loss of terminal equipment and improve the working efficiency of processing based on downlink control information.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an energy-saving method and system based on downlink control information extension. Background technique [0002] With the development of NR (New RAT, new radio access technology), more types of application scenarios and services are supported, but it brings new challenges to terminal energy saving, such as complex processing caused by flexible parameter sets Accuracy and energy consumption, energy consumption caused by new bandwidth, increased detection times due to delay requirements, energy consumption caused by more antennas, etc. [0003] Usually, the same-slot scheduling (same-slot scheduling) of PDSCH (physical downlink shared channel, physical downlink shared channel) is used in the NR technology. However, for the same-slot scheduling, the scheduled PDSCH and the scheduled PDCCH (physical downlink control channel, physical downlink control channel) a...
