The embodiment of the present application provides a kind of acquisition method and device of reference signal information, method includes: detecting the reference signal sent by first system equipment, obtains reference signal information;The reference signal information is sent to the second system network side equipment of terminal access;Wherein, the reference signal can be used for the perception measurement of second system.By terminal active detection of the reference signal of first system, reference signal information is obtained, and the reference signal information of first system is sent to the second system network side equipment of terminal access, for the perception measurement of second system, avoid the reference signal of the second system network side equipment of terminal access when reaching terminal weak, resulting in the defect that the accuracy of perception measurement result is lower, effectively improve the accuracy of perception measurement result, reduce the wireless resource spent by the second system network side equipment of terminal access to send perception signal.

This invention discloses a satellite trunking friend user coded emoji and preset phrase distribution system. It establishes a one-way friend circle for individual users by sending RACH status codes and receiving trunking signaling broadcasts. It distributes individual, group, or multi-call information using a coded emoji library or custom phrases, achieving bit-level trunking coded communication with extremely low satellite bandwidth usage. Even when satellite channel traffic is severely congested, communication remains uninterrupted. The system is based on user status services provided by the Status Server (STS), uses trunking signaling beam broadcasts provided by the Cluster Switching Center (MSCS) as the information distribution channel, utilizes status data relay services provided by the Data Server (NDS) for users who miss the broadcast to cache information, and uses the Circuit Data Support Node (CDSN) to provide user cached data download services. This provides trunking users with a novel, fast, and convenient information source coded communication method, effectively improving satellite trunking communication efficiency.

A wireless communication method and a communication device are provided. The wireless communication method comprises: a first device sending a first type of data packet to a second device before receiving a confirmation from the second device, the first type of data packet containing a data packet that has been transmitted but whether the transmission is successful is not determined.
