Abstract

The present disclosure provides a method and apparatus for determining a reference signal, and an electronic device and a storage medium, where configuration information is acquired; and it is determined that whether a reference signal is valid according to the configuration information. Determination of whether the reference signal is valid is implemented through the configuration information. Furthermore, the UE only needs to be waken up before a last synchronization signal block before a PO, and implements AGC adjustment, channel tracking and measurement through the last synchronization signal block and the reference signal.

Claims (62)

1. A method for determining a reference signal, comprising:

acquiring configuration information; and

determining whether the reference signal is valid according to the configuration information;

wherein the determining whether the reference signal is valid comprises:

determining that the reference signal after a second time point is valid, wherein the second time point is a time point with a third preset offset from starting of a paging frame (PF).

2. The method according to claim 1 , wherein the determining whether the reference signal is valid further comprises:

determining that the reference signal before a first time point is valid;

wherein the first time point is:

a time point that a paging occasion (PO) starts, or PF starts, or a first paging physical downlink control channel (PDCCH) monitoring occasion starts, or,

a time point that the PO ends, or the PF ends, or a paging PDCCH monitoring occasion ends, or,

a time point with a first preset offset from starting of the PO, or starting of the PF, or starting of the first paging PDCCH monitoring occasion, or,

a time point with a second preset offset from ending of the PO, or ending of the PF, or ending of the paging PDCCH monitoring occasion.

3. The method according to claim 2 , wherein the acquiring the configuration information comprises:

acquiring the first preset offset or the second preset offset.

4. The method according to claim 3 , wherein the acquiring the first preset offset or the second preset offset comprises:

acquiring the first preset offset or the second preset offset through high-layer parameter configuration.

5. The method according to claim 1 , wherein the acquiring the configuration information comprises:

acquiring the third preset offset.

6. The method according to claim 5 , wherein the acquiring the third preset offset comprises:

acquiring the third preset offset through high-layer parameter configuration.

7. The method according to claim 1 , wherein the determining whether the reference signal is valid further comprises:

determining that the reference signal after a second time point is valid, wherein the second time point is an end time point of a paging indication physical downlink control channel (PDCCH) monitoring occasion, or a start time point of a first paging indication PDCCH monitoring occasion.

8. The method according to claim 7 , further comprising:

after a paging indication PDCCH is not detected, determining that the reference signal is not valid.

9. The method according to claim 1 , wherein the reference signal is valid only when the reference signal is completely valid for at least one of a first time or a second time.

10. The method according to claim 1 , wherein the determining whether the reference signal is valid further comprises:

determining that the reference signal after a third time point is valid;

wherein the third time point is:

a time point with a fifth preset offset from starting of a first paging indication physical downlink control channel (PDCCH) monitoring occasion; or,

a time point with a sixth preset offset from ending of a paging indication PDCCH monitoring occasion.

11. The method according to claim 10 , wherein the acquiring the configuration information comprises:

acquiring the fifth preset offset or the sixth preset offset.

12. The method according to claim 11 , wherein the acquiring the fifth preset offset or the sixth preset offset comprises:

acquiring the fifth preset offset or the sixth preset offset through high-layer parameter configuration.

13. The method according to claim 10 , wherein the reference signal is valid only when the reference signal is completely valid for at least one of a first time or a second time.

14. The method according to claim 1 , wherein the determining whether the reference signal is valid further comprises:

determining that the reference signal after a fourth time point is valid;

wherein the fourth time point is:

a time point of a synchronization signal block burst closest to starting of a paging occasion (PO), or starting of a PF, or a first paging physical downlink control channel (PDCCH) monitoring occasion, or,

a time point with a seventh preset offset from a time point of a synchronization signal block burst closest to starting of a PO, or starting of a PF, or a first paging PDCCH monitoring occasion.

15. The method according to claim 14 , wherein the time point of the synchronization signal block burst is any one of the following:

an end time point of a synchronization signal block or a candidate synchronization signal block in a half frame or a frame, or, an end time point of a half frame or a frame comprising a synchronization signal block or a candidate synchronization signal block.

16. The method according to claim 14 , wherein the acquiring the configuration information comprises:

acquiring the seventh preset offset.

17. The method according to claim 1 , wherein the determining whether the reference signal is valid further comprises:

determining that the reference signal associated with a synchronization signal block or a detected synchronization signal block is valid; or,

determining that the reference signal in a same time interval as a synchronization signal block or a detected synchronization signal block is valid; or,

determining that the reference signal in a same time interval as a synchronization signal block burst, to which a synchronization signal block or a detected synchronization signal block belongs, is valid; or,

determining that the reference signal in a same time interval as a half frame or a frame in which a synchronization signal block burst, to which a synchronization signal block or a detected synchronization signal block belongs, is located is valid.

18. An apparatus for determining a reference signal, comprising:

at least one processor; and

a memory communicatively connected to the at least one processor; wherein

the memory stores an instruction executable by the at least one processor, and the instruction is executed by the at least one processor to cause the at least one processor to:

acquire configuration information; and

determine whether the reference signal is valid according to the configuration information;

wherein the at least one processor is further caused to:

determine that the reference signal after a second time point is valid, wherein the second time point is a time point with a third preset offset from starting of a paging frame (PF).

19. A non-transitory computer-readable storage medium storing a computer instruction, wherein the computer instruction is used to cause a computer to:

acquire configuration information; and

determine whether the reference signal is valid according to the configuration information;

wherein the computer is further caused to:

determine that the reference signal after a second time point is valid, wherein the second time point is a time point with a third preset offset from starting of a paging frame (PF).
