Abstract

A signal transmission method, a network device, a terminal and a storage medium are provided. The signal transmission method includes transmitting, by a network device, a PEI to a terminal in an idle mode or an inactive mode. The PEI includes at least one of a first power-saving signal or a second power-saving signal, the PEI is used to indicate whether the terminal is to detect paging information on PO, the PEI is transmitted before the PO, and the PO includes at least one PO or at least one PO group.

First claim

What is claimed is:

1 . A signal transmission method, comprising:
transmitting, by a network device, a Paging Early Indication (PEI) to a terminal, wherein the terminal is in an idle mode or an inactive mode, the PEI comprises at least one of a first power-saving signal or a second power-saving signal, wherein the PEI is used to indicate whether the terminal is to detect paging information on a Paging Occasion (PO), the PEI is transmitted before the PO, and the PO comprises at least one PO or at least one PO group, wherein scrambling information of the first power-saving signal comprises a cell Identity (ID), scrambling information of the second power-saving signal comprises a cell ID and a terminal group ID, and the transmitting, by the network device, the PEI to the terminal comprises: the network transmitting, on a first resource, the first power-saving signal, or the network device transmitting, on a second resource, the second power-saving signal; or the scrambling information of the first power-saving signal comprises the cell ID and comprises a first preset sequence or a second preset sequence, the scrambling information of the second power-saving signal comprises the cell ID and the terminal group ID, and the transmitting, by the network device, the PEI to the terminal comprises: the network device transmitting, on the first resource, the first power-saving signal, and/or the network device transmitting, on the second resource, the second power-saving signal, wherein in the case that the first preset sequence and the first power-saving signal scrambled with the cell ID are transmitted by the network device on the first resource, the first preset sequence and the first power-saving signal scrambled with the cell ID are detected by the terminal on the first resource and the terminal determines whether the paging information is to be detected on the PO in accordance with the first power-saving signal and does not detect the second power-saving signal, wherein in the case that the second power-saving signal is transmitted by the network device on the second resource, the second power-saving signal is detected by the terminal on the second resource and the terminal determines whether the paging information is to be detected on the PO in accordance with the second power-saving signal, and in the case that the second power-saving signal fails to be detected by the terminal on the second resource, the terminal enters a sleep state.

2 . A network device, comprising a memory, a transceiver and a processor, wherein
the memory is configured to store therein a computer program, the transceiver is configured to receive and transmit data under the control of the processor, the processor is configured to read the computer program in the memory to implement the signal transmission method according to claim 1 .

3 . A signal transmission method, comprising:
detecting, by a terminal, a PEI transmitted by a network device, the terminal being in an idle mode or an inactive mode, the PEI comprising at least one of a first power-saving signal or a second power-saving signal; determining, by the terminal in accordance with the detected PEI, whether paging information is to be detected on a PO, wherein the PEI is transmitted before the PO, and the PO comprises at least one PO or at least one PO group, wherein scrambling information of the first power-saving signal comprises a cell ID, scrambling information of the second power-saving signal comprises a cell ID and a terminal group ID, and the detecting, by the terminal, the PEI transmitted by the network device comprises: the terminal detecting, on a first resource, the first power-saving signal, or detecting, on a second resource, the second power-saving signal; or the terminal detecting, on the first resource and the second resource, the first power-saving signal and the second power-saving signal respectively; or the scrambling information of the first power-saving signal comprises the cell ID and comprises a first preset sequence or a second preset sequence, the scrambling information of the second power-saving signal comprises the cell ID and the terminal group ID, and the detecting, by the terminal, the PEI transmitted by the network device comprises: the terminal detecting, on the first resource, the first power-saving signal; in the case that the second preset sequence and the first power-saving signal scrambled with the cell ID are detected by the terminal on the first resource, the terminal detecting, on the second resource, the second power-saving signal, wherein in the case that the first preset sequence and the first power-saving signal scrambled with the cell ID are detected by the terminal on the first resource, the terminal determines whether the paging information is to be detected on the PO in accordance with the first power-saving signal and does not detect the second power-saving signal, wherein in the case that the second power-saving signal is detected by the terminal on the second resource, the terminal determines whether the paging information is to be detected on the PO in accordance with the second power-saving signal, and in the case that the second power-saving signal fails to be detected by the terminal on the second resource, the terminal enters a sleep state.

4 . The signal transmission method according to claim 3 , wherein the first power-saving signal is used for paging indication, and the first power-saving signal is a cell-specific power-saving signal;
the second power-saving signal is used for paging indication, and the second power-saving signal is a terminal group-specific power-saving signal.

5 . The signal transmission method according to claim 4 , wherein the first resource and the second resource are within a same time unit.

6 . The signal transmission method according to claim 3 , wherein the first power-saving signal is used for paging indication and the first power-saving signal is a terminal group-specific power-saving signal; and/or
the second power-saving signal is used for paging indication and the second power-saving signal is a terminal group-specific power-saving signal.

7 . The signal transmission method according to claim 6 , wherein scrambling information of the first power-saving signal comprises a cell ID and a terminal group ID; and/or
scrambling information of the second power-saving signal comprises a cell ID and a terminal group ID.

8 . The signal transmission method according to claim 7 , wherein the scrambling information of the first power-saving signal further comprises at least one of time information about paging or index information about the first power-saving signal; and/or
the scrambling information of the second power-saving signal further comprises at least one of time information about paging or index information about the second power-saving signal.

9 . The signal transmission method according to claim 8 , wherein the time information about the paging comprises at least one of:
information about a start symbol of the PO, or information about a start time of an MO corresponding to the PEI.

10 . The signal transmission method according to claim 3 , wherein patterns or resources of the power-saving signals comprised in the PEI are configured in a same time unit, and the patterns or resources of the power-saving signals comprised in the PEI have a same TCI state.

11 . The signal transmission method according to claim 10 , wherein the pattern or resource of at least one power-saving signal comprised in the PEI is configured in the same time unit, and the power-saving signals comprised in different PEIs are configured in different time units.
