Abstract: Embodiments of this application provide a resource configuration method and apparatus, so as to improve resource utilization during D2D communication. A first terminal device receives scheduling information that is sent by a network device and that is used to indicate an uplink time-frequency resource used for the first terminal device, and the first terminal device can multiplex the uplink time-frequency resource to send a sidelink signal to a second terminal device when an interference value to the network device during sending of the sidelink signal meets a first rule. Therefore, the uplink time-frequency resource of the first terminal device is multiplexed while interference is considered during sidelink transmission, thereby improving resource utilization.

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.

Abstract: This application provides an information transmission method, an apparatus, and a system, to improve coverage and transmission reliability that are of uplink control information UCI, thereby improving communication efficiency. In the method, after determining UCI, a terminal device sends the uplink control information on N frequency domain resource units, where N is a positive integer greater than 1. Based on this solution, when a power spectral density is determined, a larger quantity of frequency domain resource units may indicate a higher transmit power, so that coverage of the UCI can be increased. In addition, when a quantity of bits of the UCI is small, rate matching may be performed on the N frequency domain resource units, to reduce a code rate, so that transmission reliability is improved.
