    Abstract: A method of setup a protection mechanism for scheduled transmissions to multiple stations is introduced. Through transmitting a control frame addressing to multiple stations for immediate simultaneous responses, the transmitter would know the stations that are ready for receiving the scheduled data frames and schedule the packet for those stations. Combining the transmission of the control frame with the power saving mechanism would allow triggering a group of power saving stations to wake up at same for receiving the control frame and scheduled user data frames. A new mechanism of simultaneous group responses to the control frame with orthogonal identifier information for individual station is provided to uniquely identify the responding stations.

    Abstract: Provided are a method and system for a wireless STA to access a channel. The method includes that the wireless STA acquires a transmission ending moment of a wireless frame when selecting to refuse or drop the wireless frame and not updating a locally stored Network Allocation Vector (NAV); and the wireless STA accesses the channel when the transmission of the wireless frame is ended and a preset condition is met. According to the disclosure, a collision problem may happen to the wireless STA, and the wireless STA can access the channel only when the preset condition is determined to be met after the transmission of the wireless frame is ended, so that the problem of transmission collision with a hidden STA during the wireless frame transmission of the wireless STA is solved.

    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.

    Abstract: A system and method for generating and processing preambles in wireless communication are disclosed herein. In one embodiment, the system and method are configured to receive, from a wireless communication node, a message indicating a first sequence configuration including a set of predefined parameters and a second sequence configuration including a plurality of sets of parameters; generate a first part of a random access preamble based on the set of predefined parameters; generate a second part of the random access preamble based on selecting one of the plurality of sets of parameters; and transmit the random access preamble to the wireless communication node, wherein the first part is configured to be used by the wireless communication node to locate the second part in a time domain.
