[0112] In the embodiments of the present disclosure, the network device 102 configures a frequency domain resource for the terminal 101 to receive the LP WUS. The configuration manner can be the following manner one, manner two or manner three:

[0113] Manner one: The network device 102 configures a frequency domain resource for the terminal 101 to receive the LP WUS, which is not under the framework of a BWP.

[0114] In some embodiments, the frequency domain resource for receiving the LP WUS is configured in units of common (Common) physical resource blocks (PRBs).

[0115] In an example, the index of the frequency domain resource is determined by the starting position of the common PRB.

[0116] In an example, the starting position of the frequency domain resource is determined by the starting position of the common PRB.

[0117] In this manner one, there is no problem of BWP switching.

[0118] In some embodiments, the terminal 101 only monitors the LP WUS when the frequency domain resource position of the LP WUS is contained in the frequency domain range of the common PRB.

[0119] Manner two: The network device 102 configures a frequency domain resource for the terminal 101 to receive the LP WUS, which is under the framework of a BWP, and does not support BWP switching.

[0120] In some embodiments, under the framework of a BWP, each BWP can correspond to a physical layer channel configuration and a related parameter configuration of the BWP.

[0121] In some embodiments, the network device 102 configures a frequency domain resource for the terminal 101 to receive the LP WUS, which is located in the range of one BWP in the framework of the BWP, and the terminal 101 only monitors the LP WUS on the frequency domain resource in the one BWP and does not monitor the LP WUS in other BWPs.

[0122] In one example, the BWP framework includes four BWPs, namely BWP0, BWP1, BWP2, and BWP3. The four BWPs are used for the MR to receive and send service data.

[0123] The frequency domain resource configured by the network device 102 for the terminal 101 to receive the LP WUS is located within BWP0. The starting frequency domain position of the frequency domain resource may also be determined based on the starting frequency domain position of BWP0.

[0124] In another example, the BWP framework includes four BWPs, namely BWP0, BWP1, BWP2, and BWP3. The four BWPs are used for the MR to receive and send service data.

[0125] The frequency domain resource configured by the network device 102 for the terminal 101 to receive the LP WUS is located in BWP1. The starting frequency domain position of the frequency domain resource may also be determined based on the starting frequency domain position of BWP0.

[0126] In the second method, there is no problem of BWP switching.

[0127] In some embodiments, when the frequency domain resource location of the LP WUS is included in the frequency domain range of the activated BWP, the terminal 101 monitors the LP WUS.

[0128] In some embodiments, the subcarrier spacing of the LP WUS is the same as the subcarrier spacing corresponding to the wireless channel of the activated BWP.

[0129] In some embodiments, the length of the cyclic prefix of the LP WUS is the same as the length of the cyclic prefix corresponding to the wireless channel of the activated BWP.

[0130] Mode 3: The network device 102 configures frequency domain resources for receiving LP WUS for the terminal 101, and supports BWP switching under the BWP framework.

[0131] In some embodiments, the frequency domain resources configured by the network device 102 for the terminal 101 to receive the LP WUS are located within the framework of the BWP and include frequency domain resources within the range of different BWPs.

[0132] In some embodiments, the frequency domain resources configured by the network device 102 for the terminal 101 for receiving the LP WUS are related to the BWP index in the BWP framework. The frequency domain resources for receiving the LP WUS are respectively configured on different BWPs.

[0133] In some embodiments, the frequency domain resources configured by the network device 102 for the terminal 101 to receive the LP WUS are the same as the BWP in the framework of the BWP applied to the primary transceiver.

[0134] In an example, 4 BWPs, i.e., BWP0, BWP1, BWP2, BWP3, are included in the framework of the BWP applied to the main transceiver. The 4 BWPs are used for MR to receive and send traffic data.

[0135] The frequency domain resource configured by the network device 102 for the terminal 101 to receive the LP WUS also includes BWP0, BWP1, BWP2, and BWP3.

[0136] In some embodiments, the frequency domain resource configured by the network device 102 for the terminal 101 to receive the LP WUS is different from the BWP in the framework of the BWP applied to the main transceiver.

[0137] In an example, 4 BWPs, i.e., BWP0, BWP1, BWP2, BWP3, are included in the framework of the BWP applied to the main transceiver. The 4 BWPs are used for MR to receive and send traffic data.

[0138] The frequency domain resource configured by the network device 102 for the terminal 101 to receive the LP WUS includes 4 LR-BWPs, including LR-BWP0, LR-BWP1, LR-BWP2, and LR-BWP3.

[0139] The LR-BWP0 is located in the BWP0; the starting frequency domain position of the LR-BWP0 is based on the starting frequency domain position of the BWP0;

[0140] The LR-BWP1 is located in the BWP1; the starting frequency domain position of the LR-BWP1 is based on the starting frequency domain position of the BWP1;

[0141] The LR-BWP2 is located in the BWP2; the starting frequency domain position of the LR-BWP2 is based on the starting frequency domain position of the BWP2;

[0142] The LR-BWP3 is located in the BWP3; the starting frequency domain position of the LR-BWP3 is based on the starting frequency domain position of the BWP3.

[0194] In some embodiments, the first BWP inactivity timer time1 corresponds to the second receiver and the first receiver.

[0195] The first BWP inactivity timer time1 corresponds to the second receiver and the first receiver means that the first receiver switches according to the first BWP inactivity timer time1, and the second receiver also switches according to the first BWP inactivity timer time1.

[0196] In some embodiments, the terminal 101 switches to the default BWP after the first BWP inactivity timer time1 expires.

[0208] In some embodiments, the second BWP inactivity timer time2 corresponds to the first receiver and does not correspond to the second receiver.

[0209] The second BWP inactivity timer time2 corresponds to the first receiver and does not correspond to the second receiver, which means that the first receiver switches according to the second BWP inactivity timer time2 in the RRC configuration information, and the second receiver does not switch according to the second BWP inactivity timer time2 in the RRC configuration information, but switches according to the first BWP inactivity timer time1 in the RRC configuration information.
