For physical uplink shared channel (PUSCH) or physical downlink shared channel (PDSCH) transmission, each user equipment (UE) is scheduled by a downlink control information (DCI) in physical layer (also referred to as L1) . If UEs with requesting many services are scheduled, significant physical downlink control channel (PDCCH) resources for DCI transmission would be needed, causing much L1 signaling overhead.

In areas where there is weak terrestrial network service or no terrestrial network service, a non-terrestrial network (NTN) network may be employed to support connectivity of demanding Internet of Things (IoT) devices. In NTNs, satellites, such as Geostationary Earth Orbit (GEO) satellites or Low Earth Orbit (LEO) satellites, can provide continental local or regional services. However, special considerations must be made when using NTN networks.

Thus, the content of the scheduling information, second scheduling information, and third scheduling information should not be limited to the information related to DCI.

Another aspect of the present disclosure is related to another wireless communication method.

FIG. 3 shows a flowchart of a wireless communication method 300 according to an embodiment of the present disclosure. In one embodiment, the wireless communication method 300 can be performed by using a wireless communication device (e.g., a UE) . In the paragraph below, a wireless communication device will be used in a descriptive example, but the present disclosure is not limited in this regard. Details of the wireless communication device can be ascertained by referring to the paragraphs related to Fig. 5 below.

In one embodiment, the wireless communication method 300 includes operation 310.

In operation 310, a wireless communication device detects a piece of scheduling information from a wireless communication node. In one embodiment, the piece of scheduling information is used to schedule a plurality of wireless communication devices. In other words, in operation 310, one of the plurality of wireless communication devices detects the piece of scheduling information.

Through such an operation, the resource for transmitting transmission scheduling information can be reduced, and the congestion on the corresponding channel can be avoided.

Details of the scheduling information and relevant features can be ascertained by referring to the description above and will not be repeated herein.

In some embodiments of the present disclosure, the wireless communication method 300 further includes an operation of the wireless communication device detecting a piece of second scheduling information from the wireless communication node.

Details of the second scheduling information and relevant features can be ascertained by referring to the description above and will not be repeated herein.

In one embodiments of the present disclosure, in non-broadcast services, a data transmission or configuration applying is performed after a time offset from both of the piece of scheduling information and the second scheduling information are detected.

For example, referring to Fig. 4, between time points t41 and t42, both of the wireless communication devices WD1, WD2 in the target group detect the same piece of scheduling information. Between time points t42 and t43, the wireless communication device WD1, WD2 separately detect different pieces of second scheduling information (e.g., via carriers with different frequencies) . After a time offset (i.e., the period between time points t43 and t44) , the wireless communication device WD1, WD2 separately perform data transmission information (e.g., via carriers with different frequencies) or configuration applying during the period between time points t44 and t45.

In one embodiments of the present disclosure, the wireless communication device conducts a switching (e.g., a BWP or beam switching) in response to the scheduling information contains a BWP switching indicator or a beam switching indicator. For example, the wireless communication device can switch the BWP of data transmission to another BWP indicated by the BWP switching indicator. Or the wireless communication device can switch the beam of data transmission to another beam indicated by the beam switching indicator.

In one embodiments of the present disclosure, the wireless communication device conducts a switching (e.g., beam switching) in response to the scheduling information contains at least one of a TCI, information about a reference signal, and a BWP identity, in which the at least one of the TCI, the information about the reference signal, and the BWP identity contained by the scheduling information is different from a current serving or previous TCI, information about a reference signal, or BWP identity. In one embodiment, the reference signal reference signal may include a Channel State Information Reference Signal (CSI-RS) .

For example, under the condition that the scheduling information contains a TCI, information about a reference signal, and a BWP identity, the wireless communication device conducts a beam switching in response to any one of a current serving TCI, information about the reference signal, or BWP identity is different from their counterparts in the scheduling information.
