After the terminal device receives the first WUS, if the first WUS is the WUS 1, the terminal device may monitor the paging DCI on the PO, and receive the paging message based on scheduling of the paging DCI. If the terminal device finds that a paging list included in the paging message includes an identifier of the terminal device, the terminal device determines that the terminal device is paged, and initiates the random access procedure, that is, performs processes in the following S502 and S503.

Fei [0066] In a possible implementation, the network device may send the four SSBs, and the four SSBs have different beam directions. Because the terminal device is located in a beam direction corresponding to the SSB 1, energy for receiving the SSB 1 by the terminal device is probably higher than that of the other three SSBs. Therefore, the terminal device may select an RO corresponding to the SSB 1 to perform random access, that is, select the RO corresponding to the SSB 1 to send the random access preamble. It can be learned from the foregoing descriptions that ROs corresponding to the SSB 1 are the RO 2 and the RO 3, and the terminal device may randomly select an RO from the RO 2 and the RO 3, to send the random access preamble.

Fei [0147]; Specifically, the WUS 0 corresponds to the RO 0 and the RO 1, the WUS 1 corresponds to the RO 2 and the RO 3 (first PRACH), the WUS 2 corresponds to the RO 4 and the RO 5, the WUS 3 corresponds to the RO 6 and the RO 7, the WUS 4 corresponds to the RO 8 and the RO 9.
wherein the configuration information of the second PRACH resource is used to determine the second PRACH resource for performing the random access;
Fei [0148] In a possible implementation, the network device may send the eight WUSs whose indexes are sequentially the WUS 0 to the WUS 7, and the eight WUSs have different beam directions. It can be learned from FIG. 6 that, because the terminal device is located in a beam direction of the WUS 3, received signal strength of the received WUS 3 is probably the highest. The terminal device may randomly select an RO from the RO 6 and the RO 7 that correspond to the WUS 3, to send the random access preamble.
and a time domain resource location of the second PRACH resource is different from a time domain resource location of the first PRACH resource.

Fei [0064] In a possible implementation, the network device may send one or more synchronization signal blocks (SSBs) to the terminal device, where there is a correspondence between an SSB and an RO.
Fei [0066] In a possible implementation, the network device may send the four SSBs, and the four SSBs have different beam directions. Because the terminal device is located in a beam direction corresponding to the SSB 1, energy for receiving the SSB 1 by the terminal device is probably higher than that of the other three SSBs. Therefore, the terminal device may select an RO corresponding to the SSB 1 to perform random access, that is, select the RO corresponding to the SSB 1 to send the random access preamble. It can be learned from the foregoing descriptions that ROs corresponding to the SSB 1 are the RO 2 and the RO 3, and the terminal device may randomly select an RO from the RO 2 and the RO 3, to send the random access preamble.
Fei [0067] It is assumed that the network device respectively sends the SSB 0 to the SSB 3 by sequentially using a downlink beam 0 to a downlink beam 3. Specifically, the terminal device is located in a direction of the downlink beam 1 corresponding to the SSB 1. In a possible manner, the terminal device may adjust and/or optimize a reception beam, so that quality of receiving the SSB 1 by the terminal device is optimal. Then, the terminal device may use the adjusted and/or optimized reception beam as a transmission beam (to perform the time-frequency synchronization based on the synchronization signal) , and send the random access preamble by using the transmission beam. The network device may use, as a reception beam, the downlink beam 1 corresponding to the SSB 1, to receive the random access preamble. This improves quality of receiving the random access preamble.

After the terminal device receives the first WUS, if the first WUS is the WUS 1, the terminal device may monitor the paging DCI on the PO, and receive the paging message based on scheduling of the paging DCI. If the terminal device finds that a paging list included in the paging message includes an identifier of the terminal device, the terminal device determines that the terminal device is paged, and initiates the random access procedure, that is, performs processes in the following S502 and S503.

Shrestha [0111] For example, a WUS may be configured to indicate a UE-specific ID (e.g., IMSI or S-TMSI of UE 101). As such, RAN node 111 may determine a number of UEs 101 (e.g., a group of UEs 101) for monitoring one or more POs and transmit one or more WUSs that includes a UE-specific ID for each UE 101.
In view of Shrestha, Fei is modified such that the WUS further comprises a user equipment (UE)

[0105]; Different RO groups may be time division multiplexed, that is, occupy a same frequency domain resource but different time domain resources.
Regarding claim 14, The terminal device according to claim 10, wherein the configuration information of the synchronization signal comprises one or more of:
a transmitting period of the synchronization signal; time domain resource location information of the synchronization signal;
frequency domain resource location information of the synchronization signal;
Fei, Fig. 3 [0065]; For example, FIG. 3 is a schematic diagram of sending a random access preamble. In the schematic diagram, a horizontal axis represents time, and a vertical axis represents frequency. In the schematic diagram, four SSBs which are respectively an SSB 0, an SSB 1, an SSB 2, and an SSB 3 are included. The four SSBs are time division multiplexed, that is, occupy a same frequency domain resource but different time-frequency resources.
an antenna port of the synchronization signal; and a transmitting beam of the synchronization signal; wherein the configuration information of the synchronization signal is used to configure the terminal device that conforms to the UE identifier.
Regarding claim 15, The terminal device according to claim 14, wherein the method further comprises: determining, by the terminal device, the synchronization signal based on the configuration information of the synchronization signal, so as to perform the time-frequency synchronization based on the synchronization signal.
Fei [0064] In a possible implementation, the network device may send one or more synchronization signal blocks (SSBs) to the terminal device, where there is a correspondence between an SSB and an RO.
Fei [0066] In a possible implementation, the network device may send the four SSBs, and the four SSBs have different beam directions. Because the terminal device is located in a beam direction corresponding to the SSB 1, energy for receiving the SSB 1 by the terminal device is probably higher than that of the other three SSBs. Therefore, the terminal device may select an RO corresponding to the SSB 1 to perform random access, that is, select the RO corresponding to the SSB 1 to send the random access preamble. It can be learned from the foregoing descriptions that ROs corresponding to the SSB 1 are the RO 2 and the RO 3, and the terminal device may randomly select an RO from the RO 2 and the RO 3, to send the random access preamble.
Fei [0067] It is assumed that the network device respectively sends the SSB 0 to the SSB 3 by sequentially using a downlink beam 0 to a downlink beam 3. Specifically, the terminal device is located in a direction of the downlink beam 1 corresponding to the SSB 1. In a possible manner, the terminal device may adjust and/or optimize a reception beam, so that quality of receiving the SSB 1 by the terminal device is optimal. Then, the terminal device may use the adjusted and/or optimized reception beam as a transmission beam (to perform the time-frequency synchronization based on the synchronization signal) , and send the random access preamble by using the transmission beam. The network device may use, as a reception beam, the downlink beam 1 corresponding to the SSB 1, to receive the random access preamble. This improves quality of receiving the random access preamble.
Regarding claim 17, The network device according to claim 16, wherein the WUS is used to wake up the terminal device that conforms to the UE identifier;
Fei [0122]; Alternatively, the network device may use different WUSs to indicate whether the terminal device is to monitor the paging DCI on the PO. For example, the network device may use a WUS 1 to indicate the terminal device to monitor the paging DCI on the PO, and use a WUS 2 to indicate the terminal device not to monitor the paging DCI on the PO. After the terminal device receives the first WUS, if the first WUS is the WUS 1, the terminal device may monitor the paging DCI on the PO, and receive the paging message based on scheduling of the paging DCI. If the terminal device finds that a paging list included in the paging message includes an identifier of the terminal device, the terminal device determines that the terminal device is paged, and initiates the random access procedure, that is, performs processes in the following S502 and S503.
wherein the first information comprises one or more information of:
information for performing random access, wherein the information for performing the random access is configuration information of a first physical random access channel (PRACH) resource;
Fei [0141] Optionally, the configuration information in S500 is used to configure the correspondence between a WUS and an RO (Random Access Channel Occasion). In addition, the configuration information in S500 may further be used to configure the WUS and/or the RO. Alternatively, the network device may additionally send configuration information of the WUS to configure the WUS, and/or additionally send configuration information of the RO to configure the RO. This is not limited. Alternatively, the WUS and/or the RO are/is predefined.
Fei [0143] The configuration information of the RO may be used to configure at least one of a time domain resource, a frequency domain resource, or a random access preamble set corresponding to the RO. For example, in a specific implementation, the network device may configure a physical random access channel (PRACH) configuration index.
Fei [0144] Optionally, the network device may additionally indicate one or more of a quantity of ROs that are frequency division multiplexed in frequency domain, a frequency domain position of the 1.sup.st RO in frequency domain, an available random access preamble set, or the like.

Shrestha teaches wherein the WUS further comprises: a user equipment (UE) identifier, wherein the UE identifier is a UE ID, a UE group ID, or a cell ID;
Shrestha [0111] For example, a WUS may be configured to indicate a UE-specific ID (e.g., IMSI or S-TMSI of UE 101). As such, RAN node 111 may determine a number of UEs 101 (e.g., a group of UEs 101) for monitoring one or more POs and transmit one or more WUSs that includes a UE-specific ID for each UE 101.
In view of Shrestha, Fei is modified such that the WUS further comprises a user equipment (UE)
identifier.
Fei and Shrestha are analogous art to the claimed invention because they are in the same
field of endeavor, the configuration of WUS sent to the terminal.
It would have been obvious, before the effective filing date of the claimed invention, to a person
of ordinary skill in the art to modify Fei in a manner described above to send the WUS to UE based on
the number of UEs listening to the WUS of the cell for the RAN to keep track of the mobile subscriber
identities (Shrestha [0022]).
Regarding claim 18, The network device according to claim 17, wherein the configuration information of the first PRACH resource is used to configure the terminal device that conforms to the UE identifier;

Fei [0133]; The RO 0 corresponds to {WUS 0, WUS 1} (= configuration information of the first PRACH resource);
Fei [0122]; After the terminal device receives the first WUS, if the first WUS is the WUS 1, the terminal device may monitor the paging DCI on the PO, and receive the paging message based on scheduling of the paging DCI.
