Abstract: Embodiments provide an uplink signal acknowledge method. In the method, an uplink signal sent by a terminal device for tracking the terminal device can be received by a base station or a transmission/reception point (TRP). A downlink tracking acknowledge message can be sent to the terminal device. The downlink tracking acknowledge message can include at least one of the following: information about a status in which the base station or the TRP tracks the terminal device, timing advance information required by the terminal device to send an uplink tracking signal, power adjustment information required by the terminal device to send the uplink signal, and access control information of the terminal device. The base station or the TRP sends the downlink tracking acknowledge message to the terminal device, so that the terminal device learns whether a network has tracked the terminal device.

Abstract: The present disclosure relates to passive optical network (PON) systems, optical line terminals (OTLs), and optical network units (ONUs). One example PON system includes an OLT and at least two ONUs. The OLT and the ONUs exchange data on one downstream channel and two upstream channels. The OLT sends downstream data to each ONU on the downstream channel, where the downstream data includes an upstream bandwidth grant used to control each ONU to send upstream data. Each ONU receives the downstream data on the downstream channel, and sends the upstream data on a first upstream channel or a second upstream channel based on the upstream bandwidth grant included in the downstream data. The OLT receives, on the first upstream channel and the second upstream channel, the upstream data sent by each ONU, where a registration function is disabled on the first upstream channel, and enabled on the second upstream channel.

Abstract: A method for indicating a transmission opportunity (TXOP) duration in a wireless communication system includes generating, by a TXOP holder, a physical layer protocol data unit (PPDU). The PPDU includes a High Efficiency Signal field A (HE-SIGA), and the HE-SIGA includes a TXOP duration field. The TXOP duration field is used to indicate to other stations a remaining time for using a channel by a station. The TXOP duration field includes a first part which indicates a granularity used, and a second part which indicates the TXOP duration using the granularity indicated by the first part. The TXOP holder sends the generated PPDU.

Abstract: The present invention provides a WLAN system resource indication method and apparatus. The method includes: generating, by an access point, a frame that carries resource indication information; and sending, to multiple stations, the frame that carries the resource indication information. The resource indication information includes multiple pieces of sub resource indication information. Correspondingly, each piece of the sub resource indication information uniquely corresponds to one of the multiple stations. Therefore, a station side does not need read the entire resource indication information, so as to reduce resource overheads and improve efficiency.
