- -application number of the original application: 201780094752.0

The invention of the original application is named: method and device used in user equipment and base station for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus for a wireless signal in which a terrestrial mobile device is directly connected to a non-terrestrial network base station.

Background

Currently, a research Project (Study Item) on supporting a Non-Terrestrial Network (Study on NR to supported Non-Terrestrial Network) in 5GNR (New Radio Access Technology) has been discussed in 3GPP (3 rd generation partner Project) RAN (Radio Access Network). In the non-terrestrial network discussion, an important scenario is that the ground terminal directly accesses an aerospace Vehicle (Spaceborne Vehicle) for communication, and the aerospace Vehicle includes one or more of GEO (Geostationary Earth Orbit) satellite, MEO (Medium Earth Orbit) satellite, LEO (Low Earth Orbit) satellite, HEO (high elliptic Orbit) satellite, airborne Platform.

In the existing system, each user performs Mobility Management through its own MME (Mobility Management Entity), and the user may detect channel quality of multiple cells in real time and ensure that the user is served in a cell with better channel quality through cell reselection. For NTN (Non-Terrestrial Network) application scenarios, the above-described mobility management approach needs to be redesigned when multiple cells are maintained on one space vehicle.

Disclosure of Invention

In conventional mobility management, when a user equipment is served by a current serving cell, if a channel condition of the serving cell is found to be poor, a plurality of neighboring cells near the current serving cell are often detected, and a new cell with reliable channel quality is ensured to serve through cell reselection. In an NTN (Non-Terrestrial Network) system, one satellite often covers an extremely large number of user equipments, and in order to ensure that more users can be served simultaneously, one satellite often maintains a plurality of serving cells, and the user equipment is served in one of the serving cells. Since the channel between the satellite communication and the ground user is usually a free space scattering channel, except for the influence of rain degradation, the influence of the mobility of the user equipment, the obstruction of ground objects and the influence of ground radio interference on the channel condition will be small, and the corresponding channel quality difference will not be large no matter which cell among the multiple serving cells the user equipment is served, and further the user equipment generally does not need to perform mobility management related measurement facing the multiple serving cells.

In view of the above design, the present application discloses a solution. Without conflict, embodiments and features in embodiments in the user equipment of the present application may apply to the base station and vice versa. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.

The application discloses a method used in a user equipment for wireless communication, characterized by comprising:

-receiving first information and second information; the first information is used to determine K serving cells, K being a positive integer greater than 1, the second information is used to determine at least one of { first parameter, second parameter };

-measuring the wireless signal to determine at least one of { first measurement, second measurement };

wherein at least one of { relative relationship of the first measurement result to the first parameter, relative relationship of the second measurement result to the second parameter } is used to determine whether to perform mobility management related measurements on the K serving cells.

As an embodiment, the above method is characterized in that: the first and second parameters are applicable only when mobility management related measurements are performed on the K serving cells, i.e. when a channel quality measured by the user equipment on one of the K serving cells under one satellite meets a certain condition, the user equipment is not initiating a measurement on the K serving cells.

As an example, the above method has the benefits of: and unnecessary measurement operation is avoided, and the measurement power consumption of the user equipment is saved.

As an example, another benefit of the above method is: and notifying the K serving cells to the user equipment through the first information, thereby simplifying the operation process.

According to an aspect of the application, the method is characterized in that the ue does not perform mobility management related measurements on the K serving cells if the first measurement result is larger than the first parameter and the second measurement result is larger than the second parameter.

As an example, the above method has the benefits of: by setting the values of the first parameter and the second parameter to be low, such as-3 dB or-6 dB, frequent switching of the user equipment among a plurality of cells maintained by the satellite is avoided, power consumption is reduced, and mobility management is simplified.

As an example, another benefit of the above method is: the first and second parameters are for only cells maintained by a satellite; when a better ground cell exists around the user equipment, the first parameter and the second parameter do not cause the user equipment not to initiate handover to the ground cell, thereby avoiding performance loss.

According to one aspect of the application, the above method is characterized by comprising:

-receiving third information, the third information indicating a first list;

As an example, the above method has the characteristics and advantages that: the K Area identifiers correspond to K TA (Tracking Area), that is, the K Area identifiers correspond to K different transmission modes of the paging information; the method is convenient for distinguishing the time-frequency resource for sending the paging, avoids the collision of the paging information, and realizes the purpose of avoiding the TA information from being frequently updated due to the frequent replacement of the service cell of the user equipment by reasonably configuring the first parameter and the second parameter.

-receiving fourth information;

As an example, the features and benefits of the above method are: the target threshold is set to only perform cell reselection between the K serving cells, that is, cell reselection occurs when the channel quality of the second serving cell is better than the channel quality of the first serving cell enough, so that the probability of cell reselection between the K serving cells is ensured and the probability of occurrence of reselection is reduced; thereby reducing the power consumption and complexity of the user equipment.

-determining the second serving cell from the mobility management related measurements;

Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY301.
