Abstract: A data transmission indication method and apparatuses carrying out the method are described herein. The method includes sending, by an access point, orthogonal frequency division multiple access (OFDMA) physical layer signaling to a terminal. The OFDMA physical layer signaling indicates, to the terminal, a subchannel allocated for the terminal, so that the terminal determines the subchannel according to the OFDMA physical layer signaling. The OFDMA physical layer signaling includes an identifier of the terminal and subchannel information corresponding to the identifier of the terminal. A manner in which the access point allocates a subchannel for each terminal according to OFDMA physical layer signaling enables the access point to indicate subchannels for more terminals.

Abstract: A method for processing parking space information includes detecting, before a driver sends information for requesting an effective parking space, whether an idle parking space exists in a traveling environment of a vehicle and recording information about the idle parking space. After the driver sends the information for requesting an effective parking space, stored information about one or more effective parking spaces is then recommended to the driver.

Abstract: A positioning apparatus includes: a first positioning module configured to obtain location information of the positioning apparatus in real time; and an ultra-wide-band (UWB) positioning module configured to receive a positioning request message sent by a to-be-positioned tag, where the positioning request message includes identification information of the to-be-positioned tag. The UWB positioning module is further configured to determine, after receiving the positioning request message, whether the UWB positioning module is in a UWB base station mode. The UWB positioning module is further configured to perform, in the UWB base station mode, positioning measurement on the to-be-positioned tag based on the location information and the identification information.

Abstract: A discontinuous reception method, a terminal, and a network device are provided. The method includes: obtaining, by a terminal, discontinuous reception DRX parameter information corresponding to configuration parameter information supported by the terminal; and enabling DRX by using the obtained DRX parameter information. The method is applied to a communications system, the communications system supports N groups of configuration parameters, and each group of configuration parameters is corresponding to a group of discontinuous reception DRX parameters. A DRX parameter is corresponding to a configuration parameter, and the DRX parameter is adaptively and flexibly adjusted when the configuration parameter is flexibly adjusted based on a service in a network, so that the terminal is better balanced between a latency and power consumption, and the terminal can better adapt to a communications network with a larger system capacity, a lower latency, higher network reliability, and better network availability.

Abstract: An IAB node switching method is applied to a relay system, and the relay system includes a donor base station and a first IAB node. The donor base station provides a gateway function for the first IAB node. The first IAB node receives a first BWP configuration from the donor base station, where the first BWP configuration includes a BWP configuration of a second IAB node, and the second IAB node is a candidate upper-level node of the first IAB node. The first IAB node switches to the second IAB node. According to the IAB node switching method, the IAB node, and the donor base station that are provided in this application, service availability of an IAB node is ensured when the IAB node has a plurality of upper-level nodes.
