A method for indicating TXOP duration in a wireless communication system, comprising: generating, by a TXOP holder, a physical layer protocol data unit (PPDU), the High Efficiency Signal field A (HE-SIGA) in the PPDU carries a TXOP duration field, wherein the TXOP duration field is used to indicate the remaining time for using the channel by the station to other stations; wherein the TXOP duration field includes a first part which is used to indicate the granularity used, and a second part which is used to indicate the TXOP duration using the granularity indicated by the first part; so as that different granularities are able to be used to indicate different TXOP duration in the system; sending, the generated PPDU.

Aspects of the present disclosure provide techniques for dynamically adjusting the access link timing alignment at the integrated access and backhaul (IAB) node. Specifically, features of the present disclosure provide techniques for signaling to one or more child nodes the timing advance and timing offset values associated with each operational mode of the IAB node that may impact the access link timing for the child node (for uplink and/or downlink transmissions). Additionally or alternatively, aspects of the present disclosure identify whether a gap period may be included in order to ensure that the child node has sufficient time to transition between states during the transition period (e.g., from downlink to uplink) when the IAB node dynamically adjusts the access link timing.

A message processing method performed by a machine-to-machine (M2M) apparatus in an M2M system includes steps of: generating a request message to be transmitted to an M2M entity; transmitting the generated request message to the M2M entity; and receiving a response message for the request message from the M2M entity, where the request message, as a request for a scheduling resource, requests a reservation for the M2M entity or requests a periodic notification.

Provided are a data sending and receiving method and apparatus and a storage medium. The methods include sending a wireless signal that includes a trigger frame to one or more second communication nodes. The trigger frame is configured to trigger one or more second communication nodes to start transmission. The wireless signal carries at least one of first identifier information, second identifier information or third identifier information. The first identifier information is used to identify the sender of the trigger frame. The second identifier information is used to identify the receiver of the trigger frame. The third identifier information is used to identify that the trigger frame is configured to trigger the second communication node to start transmission.

A micro-power wireless access method and apparatus for the Internet of things for power transmission and transformation equipment involves a time synchronization process, a traffic channel access process, a control channel configuration information access process, and a control channel burst information access process. In the time synchronization process, an aggregation node determines a delay parameter and other parameters based on a timeslot in which traffic information randomly transmitted by a sensing terminal is located, and the sensing terminal adjusts transmission time of a corresponding frame based on the parameters. The traffic channel access process adopts a mode in which one-way reporting is mainly used, to minimize working time of a sensor. The present disclosure realizes limited two-way communication on a control channel, supports configuration of a sensor cycle, a threshold, and other parameters, and supports a retransmission mechanism on the control channel for important alarm information.
