Abstract: the present disclosure relates to methods and apparatuses for determining transmit power in a wireless local area network. in an example method, a station receives a trigger frame, where the trigger frame indicates a first resource unit allocated to the station. the trigger frame includes an access point (ap) transmit power subfield and an uplink target receive power subfield. the station sends a trigger-based physical layer protocol data unit (tb ppdu) at first transmit power. the tb ppdu occupies a second resource unit included in the first resource unit. the first transmit power is determined based on an indication of the ap transmit power subfield, an indication of the uplink target receive power subfield, the second resource unit, and the first resource unit.

Abstract: this application provides a communication method, apparatus, and system. the communication method includes: a first access network device (an indoor base station) obtains first information, and then sends the first information to a core network device through a control plane of a next generation (ng) interface or a general packet radio service tunnelling protocol for the user plane (gtp-u) tunnel between the first access network device and the core network device. the first information transmitted on the control plane of the ng interface or the gtp-u tunnel needs to pass through a route of a second access network device (an outdoor base station). according to this method, the indoor base station may perform ng interface-based communication with the core network device via the outdoor base station, to provide a better home network service.

Abstract: a wlan system resource indication method and apparatus are provided. 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.

IPC Code(s): H04W76/40, H04W76/10
Abstract: this application provides a session setup method and an apparatus. the method includes: when an access network device obtains a first session setup request from a first core network device, if the access network device determines that a multicast broadcast service corresponding to a first session that the first session request requests to set up is the same as a multicast broadcast service corresponding to a second session, determining that an air interface resource corresponding to the first session is the same as an air interface resource corresponding to the second session, where the first session setup request is used to request to set up the first session corresponding to a first multicast broadcast service, and the second session is a session set up between the access network device and a second core network device.
