A similar scheme can also be used for the time from the time slot (slot) where the uplink resource of the uplink (Uplink, referred to as UL) grant indication information is located to the time slot where the resource of the UL grant is located (K2 for short), but The disadvantage is that the communication protocol needs to be modified to increase the fixed part of TA and K2, etc.
For land network UEs, in order to support NTN communication, it is also necessary to implement related hardware and software checks and updates (for example, adding variables and applications, checking whether the value range of related variables will overflow, etc.), and may need to maintain related software and hardware separately. Hardware management branch, increasing the maintenance cost of software and hardware

Embodiment Construction
[0030] Those skilled in the art understand that, as mentioned in the background, the prior art solution determines the TA as the sum of the specific TA part of each UE and the fixed TA part of all UEs, and sends the fixed TA part through a system message. Similarly, a similar method may also be used from the time slot (slot) where the uplink resource indicated by the uplink (Uplink, UL) grant (abbreviated as UL) is located to the time when the slot where the UL grant is located (K2 for short) is received. However, the current determination method of TA and K2 will cause the values of TA and K2 to greatly exceed the value ranges of TA and K2 currently defined in the land network.
[0031] Take 15kHz subcarrier spacing as an example, such as figure 1 As shown, the one-way transmission delay from time slot 0 where the frame of the network base station (for example, gNodeB (gNB for short)) to the UE receiving the frame data is more than 5ms, and the RTT between gNB and UE is mor...

The invention discloses a user equipment parameter determination method and device, a storage medium and a base station. The determination method comprises the following steps: determining the minimumround-trip time between each user equipment in a cell and a satellite; determining frame information of a network side uplink wireless frame according to the minimum round-trip time and the frame information of the network side downlink wireless frame, wherein the minimum round-trip time is a time difference of the network side uplink wireless frame lagging behind the network side downlink wireless frame; and determining user equipment parameters of each user equipment based on the network side uplink radio frame and the network side downlink radio frame, wherein the user equipment parametersare TA and / or K2. Through the technical scheme provided by the embodiment of the invention, the NTN network can be supported on the premise of reducing software and hardware modification of the landnetwork UE as much as possible, and the software and hardware maintenance cost is effectively prevented from being increased.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for determining user equipment parameters, a storage medium, and a base station. Background technique [0002] The 3rd Generation Partnership Project (3GPP) is researching the fifth-generation mobile communications (The Fifth-Generation mobile communications, 5G) New Radio (NR) non-terrestrial communication network (Non Terrisal) Network, referred to as NTN). The research scope of 5G NTN mainly includes spaceborne vehicles (Spaceborne vehicle) geostationary satellites (Geostationary Earth Oribit Satellites, referred to as GEO) / medium orbit satellites (Medium Earth Oribiting Satellites, referred to as MEO) / low orbit satellites (Low Earth Oribit Statellites, referred to as LEO) ) and airborne vehicles (airbornevehicle) high-altitude platforms (High Altitude Platforms, referred to as HAPS). The main feature of NTN is that its round tr...
