Problems solved by technology

For NTN application scenarios, space vehicles with higher orbits will cover a large number of users. If a space vehicle corresponds to a base station, obviously the above paging will cause a large number of UEs to search for paging information on the same PF / PO, and then cause collisions and unnecessary loss of power consumption

Abstract

The invention discloses user equipment for wireless communication, and a method and a device in network equipment. The method comprises the following steps that: user equipment determines a first time-frequency resource subset from a first time-frequency resource set, and monitors a first wireless signal in the first time-frequency resource subset; Wherein the location-related information of the user equipment is used for determining the first time-frequency resource subset from the first time-frequency resource set, and the first wireless signal comprises paging-related information. Accordingto the method and the device, the time-frequency resource for transmitting the paging related information of the user equipment is connected with the position related information of the user equipment through design; the problem of paging information collision caused by the fact that all user equipment shares one set of paging scheme and the problem of power consumption waste of user equipment receiving when a non-ground network base station covers a large number of user equipment are avoided; And therefore, the paging information transmission efficiency and the overall system performance areimproved.

Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, in particular to a transmission method and device for a wireless signal with a relatively long transmission delay. Background technique [0002] At present, the research project (Study Item) on supporting non-terrestrial networks in 5G NR (New Radio Access Technology, new radio access technology) has been published in 3GPP (3rd Generation Partner Project, third generation partnership project) RAN (Radio Access Network , wireless access network) are discussed. In the discussion of non-ground networks, an important scenario is that ground terminals are directly connected to spaceborne vehicles (Spaceborne Vehicle) for communication, and spaceborne vehicles include GEO (Geostationary Earth Orbiting, geosynchronous Earth orbit) satellites, MEO (MediumEarth Orbiting, One or more of medium earth orbit) satellites, LEO (Low Earth Orbit, low earth orbit) sa...
