Abstract

An apparatus includes one or more processors and a memory having instructions stored thereon that, when executed by the one or more processors, cause the apparatus to receive a first wake-up signal. The first wake-up signal is one of K wake-up signals, K is an integer greater than or equal to 1, and the K wake-up signals are quasi co-located with K synchronization signal blocks (SSBs), K channel state information-reference signals (CSI-RSs), or K demodulation reference signals (DMRSs). The apparatus is also caused to determine M paging occasions. There is a correspondence between the K wake-up signals and the M paging occasions, and M is an integer greater than or equal to 1. The apparatus is further caused to receive, on the M paging occasions, downlink control information (DCI) used for paging.

First claim

receive a first wake-up signal, wherein
the first wake-up signal is one of K wake-up signals,
K is an integer greater than or equal to 1, and
the K wake-up signals are quasi co-located with K synchronization signal blocks (SSBs), K channel state information-reference signals (CSI-RSs), or K demodulation reference signals (DMRSs);
determine M paging occasions and a first physical downlink control channel PDCCH) monitoring occasion in the M paging occasions, wherein
there is a correspondence between the K wake-up signals and the M paging occasions, there is a correspondence between the first wake-up signal and the first PDCCH monitoring occasion, and one of the M paging occasions comprises K PDCCH monitoring occasions, and the first PDCCH monitoring occasion is one of the K PDCCH monitoring occasions, and
M is an integer greater than or equal to 1;
receive downlink control information (DCI) used for paging on the first PDCCH monitoring occasion in the M paging occasions.

2. The apparatus according to claim 1 , wherein the correspondence between the first wake-up signal and the first PDCCH monitoring occasion comprises one or more of:
a correspondence between a time domain resource of the first wake-up signal and the first PDCCH monitoring occasion;
a correspondence between a frequency domain resource of the first wake-up signal and the first PDCCH monitoring occasion;
a correspondence between a code domain resource of the first wake-up signal and the first PDCCH monitoring occasion;
a correspondence between a spatial domain resource of the first wake-up signal and the first PDCCH monitoring occasion;
a correspondence between a sequence of the first wake-up signal and the first PDCCH monitoring occasion; or
a correspondence between an identifier of the first wake-up signal and the first PDCCH monitoring occasion.

3. The apparatus according to claim 1 , wherein the K wake-up signals are generated based on an identical sequence.

4. The apparatus according to claim 1 , wherein K is an integer greater than or equal to 2.

5. The apparatus according to claim 4 , wherein the K wake-up signals occupy different frequency domain resources.

6. A communication method, comprising:

7. The method according to claim 6 , wherein the correspondence between the first wake-up signal and the first PDCCH monitoring occasion comprises one or more of:
a correspondence between a time domain resource of the first wake-up signal and the first PDCCH monitoring occasion;
a correspondence between a frequency domain resource of the first wake-up signal and the first PDCCH monitoring occasion;
a correspondence between a code domain resource of the first wake-up signal and the first PDCCH monitoring occasion;
a correspondence between a spatial domain resource of the first wake-up signal and the first PDCCH monitoring occasion;
a correspondence between a sequence of the first wake-up signal and the first PDCCH monitoring occasion; or
a correspondence between an identifier of the first wake-up signal and the first PDCCH monitoring occasion.

8. The method according to claim 6 , K is an integer greater than or equal to 2.

9. The method according to claim 8 , wherein the K wake-up signals occupy different time domain resources.

10. An apparatus, comprising:
one or more processors; and
one or more memories having instructions stored thereon that, when executed by the one or more processors, cause the apparatus to:
send a first wake-up signal, wherein
