Abstract

A signal processing method and a signal processing apparatus are provided in the present application. A network device configures a paging early indication for a terminal device in an idle state, where the paging early indication is used for indicating monitoring of a physical downlink control channel (PDCCH) of at least one paging occasion, and/or monitoring of at least one PDCCH with different paging contents; after the network device sends the paging early indication to the terminal device, the terminal device can accurately indicate physical downlink control channel (PDCCH) monitoring at a paging occasion, which avoids unnecessary false wake-up or non-wake-up caused by a paging occasion conflict, thereby reducing power consumption of the terminal device.

First claim

The invention claimed is:

1 . A signal processing method, comprising:
configuring, by a network device, a paging early indication for a terminal device in an idle state, wherein the paging early indication is used for indicating at least one of the following: monitoring of a physical downlink control channel (PDCCH) of at least one paging occasion, monitoring of at least one PDCCH with different paging contents; sending, by the network device, the paging early indication to the terminal device; wherein the paging early indication is downlink control information (DCI), and a bit field of the DCI at least identifies one of the following: indication information about whether to monitor a paging PDCCH of a terminal or a terminal group under different paging occasions (POs) corresponding to at least one paging frame (PF) identifier, indication information about whether to monitor paging PDCCHs corresponding to M terminals or M terminal groups, indication information about whether to monitor paging PDCCHs corresponding to N terminals or N terminal groups; wherein M and N are natural numbers greater than or equal to 1, or the paging early indication is DCI, and a bit field of the DCI at least identifies one of the following: indication information about whether to monitor a paging PDCCH of a terminal or a terminal group under different monitoring occasions (MOs) of different POs corresponding to at least one PF identifier, indication information about whether to monitor paging PDCCHs corresponding to M terminals or M terminal groups, indication information about whether to monitor paging PDCCHs corresponding to N terminals or N terminal groups; wherein M and N are natural numbers greater than or equal to 1.

2 . The method according to claim 1 , wherein the paging early indication is used for indicating at least one of the following: an identifier of a paging frame within a paging cycle, an identifier of an MO of a first paging PDCCH of a first paging occasion comprised in a paging frame, an identifier of a paging occasion group in a paging frame, a terminal identifier or a terminal group identifier of a paging occasion in a paging frame, an identifier indicating a paging occasion, a sequential number indicating a paging occasion within a paging cycle, an identifier indicating a paging frame and a paging occasion in the paging frame, or an identifier indicating whether to monitor a PDCCH; wherein the paging occasion group comprises at least one paging occasion.

3 . The method according to claim 2 , wherein the identifier of the paging frame comprises: a unique identifier of the paging frame within the paging cycle, or a serial number of the paging frame within the paging cycle, or an identifier of a time-domain position where the paging frame is located; and/or,
the identifier of the MO of the first paging PDCCH of the first paging occasion comprises: a unique serial number of the MO in the paging frame, or indication information about a time-domain position where the MO is located; and/or, the identifier of the paging occasion group in the paging frame comprises at least one of the following: a unique serial number of the paging occasion group in the paging frame, an identifier of a time-domain position of the paging occasion group, a unique serial number of an MO of a first paging PDCCH in each paging group of the paging occasion group, or an identifier of a time-domain position of a first paging occasion of the paging occasion group; and/or, the terminal identifier or the terminal group identifier of the paging occasion in the paging frame comprises: a unique serial number of a terminal or a terminal group in the paging frame, or a relative serial number of a terminal or a terminal group in the paging frame; and/or, the identifier indicating the paging occasion comprises: a unique serial number in the paging occasion, or an identifier of a time-domain position in the paging occasion, or an identifier of a first MO for paging in the paging occasion; wherein the identifier of the first MO for paging in the paging occasion comprises a unique serial number of the MO, or an identifier of a time-domain position of the MO; and/or, the identifier indicating the paging frame and the paging occasion in the paging frame comprises: a unique serial number of the paging frame within a paging cycle, or an identifier of a time-domain position of the paging frame.

4 . The method according to claim 1 , wherein the bit field of the DCI is further used for identifying an identifier of a PF; or
an identifier of a PF is preconfigured; or a PO identifier and a paging indication are indicated in the DCI; wherein quantities of bits corresponding to different POs are different.

5 . The method according to claim 1 , wherein the paging early indication is a sequence, and the sequence is associated with a PF identifier, a PO identifier, an MO identifier.

6 . The method according to claim 5 , wherein an initial sequence of the sequence meets any one of the following:
the initial sequence=F(a PF frame identifier, a PO identifier); or, the initial sequence=F(a PF frame identifier, an identifier of a starting slot of a PO, an identifier of a starting symbol of the PO); or, the initial sequence=F(a PF frame identifier, a starting serial number of a PO); or, the initial sequence=F(a PF frame identifier, an identifier of a starting MO in a PO); or, the initial sequence=F(a PF frame identifier, a slot identifier of a starting MO, a symbol identifier of the starting MO); or, the initial sequence=F(a PF frame identifier, a serial number of a starting MO); or, the initial sequence=F(an identifier of a starting MO in a PO); or, the initial sequence=F(a slot identifier of a starting MO, a symbol identifier of the starting MO); or, the initial sequence=F(a serial number of a starting MO); wherein F denotes a function operation relationship.

7 . A signal processing apparatus, comprising a memory, a transceiver and a processor;
the memory is configured to store a computer program; the transceiver is configured to receive and send data under control of the processor; the processor is configured to read the computer program in the memory and perform the method according to claim 1 .

8 . A signal processing method, comprising:
receiving, by a terminal device, a paging early indication from a network device, wherein the terminal device is in an idle state, and the paging early indication is used for indicating at least one of the following: monitoring of a physical downlink control channel (PDCCH) of at least one paging occasion, monitoring of at least one PDCCH with different paging contents; performing, by the terminal device, data processing according to the paging early indication; wherein the paging early indication is downlink control information (DCI), and a bit field of the DCI at least identifies one of the following: indication information about whether to monitor a paging PDCCH of a terminal or a terminal group under different paging occasions (POs) corresponding to at least one paging frame (PF) identifier, indication information about whether to monitor paging PDCCHs corresponding to M terminals or M terminal groups, indication information about whether to monitor paging PDCCHs corresponding to N terminals or N terminal groups; wherein M and N are natural numbers greater than or equal to 1, or the paging early indication is DCI, and a bit field of the DCI at least identifies one of the following: indication information about whether to monitor a paging PDCCH of a terminal or a terminal group under different monitoring occasions (MOs) of different POs corresponding to at least one PF identifier, indication information about whether to monitor paging PDCCHs cor
