Abstract: A transmitter sends a PPDU including a signature symbol to a receiver, where a first preset bit in the signature symbol indicates a standard version corresponding to the PPDU and/or a value of each bit in a second preset bit is 0 or 1. After the receiver receives the PPDU, if the standard version corresponding to the PPDU indicated by the first preset bit in the signature symbol in the PPDU is a standard version corresponding to a first PPDU and/or the value of each bit in the second preset bit in the signature symbol is the same as the preset value, the receiver determines that the received PPDU is the first PPDU. the transmitter and the receiver determine, by using the signature symbol in the PPDU, whether the received PPDU is the first PPDU, to identify the first PPDU, so that information in the received PPDU is correctly interpreted.

Abstract: Embodiments of this application relate to the communications field, and in particular, to an information indication method and apparatus in the communications field. The embodiments of this application include: generating a PPDU including radar indication information, where the radar indication information is used to indicate that the PPDU is a PPDU used for radar testing, and transmitting the PPDU. According to the method provided in the embodiments of this application, the transmit end explicitly indicates that the PPDU is a PPDU used for radar testing rather than a PPDU used for communication between communications devices. When a receive end receives the PPDU, the receive end no longer monitors a channel, thereby reducing power consumption of the receive end.

Abstract: This application provides a method for transmitting a wake-up packet in a communications system and a device. The communications system includes a transmit end device and a receive end device. The receive end device includes a wake-up receiver and a main transceiver. The method includes: sending, by the transmit end device, a first wake-up packet WUP to the wake-up receiver by using a first data rate; determining, by the transmit end device, a second data rate; and sending, by the transmit end device, a second WUP to the wake-up receiver by using the second data rate. The transmit end device can determine a proper data rate for sending a wake-up packet based on a specific transmission condition in a communication process, thereby improving transmission efficiency of the wake-up packet.

Abstract: The disclosure relates to an information indication method, an information receiving method, and an apparatus. The information indication method includes: sending, by an access point, a data frame to at least one station, where the data frame is a non-aggregated frame or an aggregated frame obtained by aggregating N MAC frames, N is a positive integer greater than 1 and is less than or equal to M, and M is a maximum allowable quantity of aggregated MAC frames; sending, by the access point, trigger information to the at least one station, where the trigger information is used to instruct the at least one station to reply with an acknowledgement frame on a shared resource unit; and receiving, by the access point, the acknowledgement frame fed back by the at least one station on the shared resource unit.

Abstract: The present disclosure relates to communication methods, apparatus, and systems. One example method includes sending, by an access point, a first beacon frame, where the first beacon frame is used to schedule a first-type station set, a target wake time (TWT) information element in the first beacon frame includes first indication information, and the first indication information is used to indicate to the first-type station set that a first TWT service period is provided to a second-type station set for use, and sending, by the access point, a second indication frame in the first TWT service period, where the second indication frame is used to schedule the second-type station set, and a bandwidth specification of a physical packet carrying a beacon frame for scheduling the first-type station set is different from a bandwidth specification of a physical packet carrying an indication frame for scheduling the second-type station set.

Abstract: This application relates to the wireless communications field and provides a frame transmission method, device, and system. The method includes: sending, by a second device, n wake-up frames to a first device, where the n wake-up frames each carry segmented content of wake-up signaling, so that a wake-up receiver of the first device wakes up a main transceiver of the first device based on the n wake-up frames, and after being woken up, the main transceiver sends, to the second device, a response frame used to indicate whether the n wake-up frames are correctly received. In this application, content of the wake-up signaling is segmented. In this case, lengths of the n wake-up frames are all relatively short, so that the wake-up receiver is easier to correctly receive each wake-up frame.

Abstract: Methods and apparatuses of parallel data transmission are disclosed. In one embodiment, a first node generates a physical protocol data unit (PPDU) that carries indication information. The indication information is used to indicate whether a second node is allowed to perform parallel data transmission by spanning a time length of the PPDU and indicate a boundary crossing time length of the parallel data transmission. The first node is included in a first basic set service (BSS), and the second node is included in a second BSS. The first node sends the PPDU.
