As shown in fig. 1, the power saving method based on the downlink control information extension may include the following operations:
101. and detecting the physical downlink control channel scheduled by the downlink control information in the unit time slot.
As for the slot, it is known in the prior art that the basic time unit for downlink resource scheduling in NR is one slot (slot), and in general, one slot may be composed of 14 OFDM symbols in time. The network equipment transmits a Physical Downlink Shared Channel (PDSCH) and a Physical Downlink Control Channel (PDCCH) for the terminal equipment. Since the DCI carried by the PDCCH includes relevant information required for receiving the PDSCH, where the relevant information may be, for example, PDSCH time-frequency resource location and size or multi-antenna configuration information, the terminal device needs to demodulate the PDCCH first in order to correctly receive the PDSCH.
The unit slot in the present embodiment may be referred to as an initial slot, and may be exemplarily implemented as a 0 th slot. The detection of the physical downlink control channel scheduled by the downlink control information in the 0 th time slot can be realized by analyzing the downlink control information.
102. And calling a plurality of physical downlink shared channels through the physical downlink control channel.
The physical downlink control channel comprises scheduling information of a plurality of physical downlink shared channels, so that simultaneous scheduling of the physical downlink control channel and the physical downlink shared channels can be ensured. The specific implementation is that the base station associated with the physical downlink control channel performs configuration based on a scheduling algorithm, and in the downlink-based control information sent by the physical downlink control channel, the information related to time-frequency domain resources, code rates and the like of the physical downlink shared channel to be scheduled can be carried, and the configuration can be performed on the base station side according to other scheduling requirements.
103. And respectively executing the physical downlink control channel and the plurality of physical downlink shared channels.

Further, in order to ensure that the execution physical downlink control channel and the plurality of physical downlink shared channels are not in the same time slot, a cross-time-slot scheduling interval is determined according to the execution time slot of the physical downlink control channel and the execution time slots of the plurality of physical downlink shared channels, and a detection period for detecting the downlink control information is configured to be greater than the cross-time-slot scheduling interval. Illustratively, if the interval between the time slot for performing the pdcch processing and the time slot for performing the pdcch processing is Kmin, the condition T > Kmin must be satisfied for the detection period T for detecting the downlink control information.
To better understand the method disclosed in this embodiment, exemplarily, as shown in fig. 2, for a schematic diagram of time slot scheduling combined with multiple physical downlink shared channel scheduling, when a 0 th time slot is detected, first, physical downlink control channel detection is performed, and when a first physical downlink control channel, that is, PDCCH0 is detected, this PDCCH0 schedules PDSCH0, PDSCH1 and PDSCH2 having an association relationship with them. After PDCCH1 detection up to the sixth slot, PDSCH3 and PDSCH4 are simultaneously scheduled by PDCCH1 at intervals of 1 slot. Therefore, the cross-time slot scheduling of the physical downlink control channel and the physical downlink shared channel is ensured, and the requirement of simultaneously scheduling a plurality of physical downlink shared channels is met.
According to the method disclosed by the embodiment, the PDCCH and the PDSCH are processed without being performed in the same time slot, so that the problems of energy loss of terminal equipment and reduction of processing speed caused by the fact that a user needs to create a buffer in advance to reserve the PDSCH when the PDCCH and the PDSCH are processed in the same time slot are solved. Therefore, the working efficiency is greatly improved, unnecessary energy consumption is saved, the frequency of PDCCH detection is effectively reduced, and the dormant time slot of the PDCCH is increased to achieve the energy-saving effect.
