Abstract

Claims (38)

1 . A signal receiving method, implemented by a user equipment (UE), comprising:

receiving a paging early indication (PEI) signal before a paging occasion (PO), wherein the PEI signal is used for indicating whether the UE receives the PO in a paging cycle, a time domain position of the PEI signal is determined by a distance between the PEI signal and a reference point before the PO, a position of the reference point is determined by a first higher-layer parameter, and the distance between the PEI signal and the reference point is determined by a second higher-layer parameter; and

performing a predefined operation based on the PEI signal.

2 . The method of claim 1 , wherein the predefined operation comprises at least one of:

receiving the PO;

not receiving the PO; or

receiving paging downlink control information (DCI).

3 . The method of claim 1 , wherein the PEI signal comprises an indication of a reference signal resource or a reference signal resource set;

wherein the indication of the reference signal resource or the reference signal resource set comprises one of:

whether the reference signal resource or the reference signal resource set exists;

whether the UE needs to perform blind detection on the reference signal resource or the reference signal resource set; or

whether the reference signal resource or the reference signal resource set is updated or activated or deactivated.

4 . The method of claim 1 , wherein a relationship between the PEI signal and the reference point comprises at least one of the following:

a synchronization signal block (SSB) exists between a starting position of the PEI signal and the reference point;

an SSB exists between an ending position of the PEI signal and the reference point; or

an SSB exists between the PO and the reference point.

5 . The method of claim 1 , further comprising one of:

in response to determining that the PEI signal is not detected on a PEI time-frequency domain resource or that no PEI detection opportunities exist in the paging cycle, receiving, by the UE, the PO;

in response to determining that the PEI signal is not detected on a PEI time-frequency domain resource or that no PEI detection opportunities exist in the paging cycle, not receiving, by the UE, the PO; or

in response to determining that the PEI signal is not detected on a PEI time-frequency domain resource or that no PEI detection opportunities exist in the paging cycle, whether the UE receives the PO is determined by a higher-layer parameter.

6 . The method of claim 1 , further comprising:

in a case where a resource overlap occurs between a PEI time-frequency resource and a non-PEI time-frequency resource, performing a predefined operation based on a resource overlap situation.

7 . The method of claim 6 , wherein performing the predefined operation based on the resource overlap situation comprises:

receiving a signal with a high priority according to predefined priorities, wherein the predefined priorities comprise at least one of the following cases:

in response to determining that the PEI time-frequency resource overlaps with a physical downlink shared channel (PDSCH) time-frequency resource, a priority of the PEI signal and a priority of a PDSCH are determined by a type of information carried by the PDSCH and a type of a radio network temporary identifier (RNTI) that scrambles a physical downlink control channel (PDCCH) for scheduling the PDSCH; or

in response to determining that a resource overlap occurs between the PEI time-frequency resource and a random access response window, a priority of the PEI signal and a priority of an access response are determined by a reason for triggering the random access response window.

8 . The method of claim 6 , wherein in a case where the PEI signal is indicated by DCI, performing the predefined operation based on the resource overlap situation comprises at least one of:

in response to determining that a resource overlap occurs between the PEI signal and at least one of another signaling or signal, monitoring the PO; or

in response to determining that a resource overlap occurs between the PEI signal and at least one of another signaling or signal, determining, based on a higher-layer configuration, whether to monitor the PO.

9 . A device, comprising:

at least one processor; and

a memory configured to store at least one program;

wherein the at least one program is executed by the at least one processor to cause the at least one processor to perform the method of claim 1 .

10 . A non-transitory computer readable storage medium, which is configured to store a computer program which, when executed by a processor, causes the processor to perform the method of claim 1 .

11 . A signal sending method, implemented by a base station, comprising:

sending a paging early indication (PEI) signal before a paging occasion (PO), wherein the PEI signal is used for instructing a user equipment (UE) to perform a predefined operation based on the PEI signal, a time domain position of the PEI signal is determined by a distance between the PEI signal and a reference point before the PO, a position of the reference point is determined by a first higher-layer parameter, and the distance between the PEI signal and the reference point is determined by a second higher-layer parameter.

12 . The method of claim 11 , further comprising:

in a case where a resource overlap occurs between a PEI time-frequency resource and a non-PEI time-frequency resource, performing a predefined operation based on a resource overlap situation.
