    Abstract: A wireless signal transmission method includes: transmitting, by a transmitting station, a wireless signal to a plurality of receiving stations, wherein the wireless signal comprises a first portion and a second portion, the first portion being a trigger frame with a first type of frame format which can be independently decoded, the second portion being a specific signal with a second type of frame format; and receiving, by the transmitting station, a radio frame transmitted by at least one of the plurality of receiving stations. The wireless signal transmission method provided by the present disclosure are used to solve the problems in the prior art that a trigger frame is not able to complete transmission resources reservation and trigger multi-user transmission at the same time as satisfying the training accuracy required for uplink multi-user transmission.

    Abstract: Provided are an information indication method and apparatus, a device and a storage medium. The information indication method includes: dividing beam identifier (ID) information into first beam ID information and second beam ID information according to a preset rule, where the first beam ID information and the second beam ID information are used for instructing a second node to obtain the beam ID information based on the preset rule; carrying the first beam ID information on a first resource and transmitting the first beam ID information to the second node; and carrying the second beam ID information on a second resource and transmitting the second beam ID information to the second node.

    Abstract: Techniques are described for selecting root pairs for Zadoff-Chu sequences for random access preamble and for signaling one or more values associated with the root pair to a user equipment (UE) by a base station. The described root pair selection methods for two-root physical random access channel (PRACH) preamble can enable the peak differences received at the UE from different frequency offsets (FOs) to be disjointed even considering error in UE side. The selection techniques can improve the performance of PRACH FO and time offset (TO) estimation.
