Technical Field

Background

In Non-Terrestrial communication Networks (NTN), cells typically have a large coverage area.

The NTN supports the relation between two beams (Beam) and a Cell (Cell) and supports two Beam layout structures, wherein in one layout structure, a Synchronization Signal Block (SSB) is transmitted on the small Beam (small Beam), and a broadcast message received by a terminal is the broadcast message of the Beam where the terminal is located; in another arrangement, the SSB is transmitted on an umbrella beam (umbrella beam), and the broadcast message received by the terminal contains broadcast messages of all beams, wherein the broadcast messages of all beams are the same or different. For example, for an IDLE (IDLE)/active (INACTIVE) User terminal (UE), the beam layout structure adopted by the network is different, and the behavior of the terminal performing cell reselection based on a broadcast message is also different. However, in NTN, there is no method for enabling a UE to perform cell reselection under different beam layout structures.

The method for cell reselection provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings by some embodiments and application scenarios thereof.

As shown in fig. 2a, an embodiment of the present invention provides a method 200 for cell reselection, which may be performed by a terminal device, in other words, by software or hardware installed in the terminal device, and includes the following steps:

s202: the terminal obtains at least one target configuration information associated with the target beam.

In an implementation manner, when the target configuration information is one, the target beam is a beam where the terminal is located. The terminal resides in the beam, or is in the coverage of the beam, or accesses the network through the beam, or communicates data with the network through the beam, and the beam can be regarded as the beam where the terminal is located. At this time, the target configuration information acquired by the terminal may be one. For example, the network device sends the target configuration information to the terminal, and the terminal receives the target configuration information.

Generally, this step may be performed in an NTN network. NTN cells have large coverage area, in which case different neighbor frequencies may be faced for UEs camping in the same cell. But the cell configuration parameters broadcasted through the system information are applied to all UEs in the cell, which may cause the UEs to make unnecessary measurements. Specifically, for example, as shown in fig. 2b, the neighboring cells of the Cell1 (Cell 1) include Cell 2 and Cell 3, and for the coverage of the UE1 residing in Cell1 in Cell 2, the coverage of the UE2 residing in Cell1 in Cell 3, the cells with different frequencies may belong to Cell 2 and Cell 3, and may have different frequency priorities. If the same configuration parameters are applied to the UE1 and the UE2, assuming that the priority of the frequency point 2 is higher than the frequency point 1 and higher than the frequency point 3, according to the Cell reselection rule, for the frequency point with the high priority, the measurement of the neighboring Cell is always performed, so that the UE2 may unnecessarily measure the Cell 2 of the frequency 2.

As shown in fig. 2c, in the NTN Beam coverage area, the following mapping relationship between two beams (Beam) and Cell can be supported:

(1) One Cell corresponds to one Beam, if Beam0 belongs to Cell 0, beam 1 belongs to Cell 1;

(2) One Cell corresponds to a plurality of beams, such as Beam 0/1/2/3 belongs to the same Cell, and Beam 5/6 belongs to another Cell; or Beam 0/1/2/3/4/5/6 belong to one Cell, and the like.

S204: performing cell reselection based on the target configuration information.

In an implementation manner, when the target configuration information is one, the target beam is a beam where the terminal is located, and in this step, cell reselection is performed based on the target configuration information associated with the beam where the terminal is located.

The NTN supports the relationship between two beams and cells, and supports two beam layout structures, as shown in fig. 2d, in one layout structure, the SSB is transmitted on a small beam, and the broadcast message received by the terminal is the broadcast message of the beam where the terminal is located. In another arrangement, shown in fig. 2e, the SSB is transmitted on the umbrella beam and the broadcast message received by the terminal contains the broadcast messages of all beams, wherein the broadcast messages of all beams are the same or different.

In the case that one cell corresponds to a plurality of beams, for example, beam 0/1/2/3/4/5/6 belongs to cell1, UE1 and UE2 both reside in cell1, the Beam where UE1 is located is Beam0, and the Beam where UE2 is located is Beam6.

In the case that the target configuration information is sent in smallbeam, UE1 and UE2 may obtain the target configuration information of the located beam, for example, UE1 obtains the configuration information of beam0, UE2 obtains the configuration information of beam6, and UE1 and UE2 perform cell reselection based on the target configuration information of the located beam, respectively, so as to avoid unnecessary measurement.

In the case where the target configuration information is transmitted in the umbrella beam, UE1 and UE2 may acquire a plurality of target beams and the target configuration information, and UE1 and UE2 may select one target configuration information based on the beam where it is located and perform cell reselection based on the target configuration information, thereby avoiding unnecessary measurements.

The method for reselecting the cell provided by the embodiment of the invention comprises the steps that at least one piece of target configuration information associated with a target wave beam is obtained through a terminal; performing cell reselection based on the target configuration information, the cell reselection being capable of being performed under different beam layout structures in the NTN.

According to the cell reselection method provided by the embodiment of the invention, the target beam is the beam where the terminal is located, so that unnecessary measurement and power consumption of terminal equipment can be avoided.

In one implementation, the association relationship between the target beam and the target configuration information may include one of the following relationships:

an association between one of said target beams and one of said target configuration information;

an association between a plurality of the target beams and one of the target configuration information.

In one implementation, the target configuration includes at least one of:

information related to cell reselection of the same-frequency neighbor cell;

and information related to the cell reselection of the pilot neighbor cell.

In one implementation, the information related to the co-frequency neighbor cell reselection includes at least one of:

information that co-frequency neighbor cells are forbidden or reserved;

a white list of the same-frequency neighbor cells;

and (4) carrying out a blacklist of the same-frequency neighbor cells.

identifying an adjacent cell of the different frequency;

network type of the adjacent cell of the different frequency;

forbidden information of the different-frequency adjacent cell;

information that the pilot neighbor cell is reserved;

reselection parameters related to the pilot frequency adjacent cells;

and (4) a black list of the pilot frequency cells.

In one implementation, the behavior of the terminal for acquiring at least one target configuration information associated with a target beam may be predetermined, for example, by a protocol.

As shown in fig. 3, an embodiment of the present invention provides a method 300 for cell reselection, which may be performed by a terminal device, in other words, by software or hardware installed in the terminal device, and includes the following steps:

s302: the terminal obtains at least one target configuration information associated with the target beam.

1. the first target beam is associated with first target configuration information, wherein the first target beam is an nth target beam and the first target configuration information is an nth element in the first list.

Where n is the sequential number of the target beam in some optional ordering. The first list contains at least one first configuration information, wherein the elements in the first list may be the same or different. For example, the cell includes 4 beams, the network broadcasts a first list, the first list includes 4 first configuration information, that is, list1= { info1, info2, info3, info4}, an nth element in the list is configuration information of an nth beam, for example, a 2 nd element in the list is configuration information of a beam 2, where the elements in the first list may be the same or different.

For another example, the second list is: list2= { List5_1, list5_2 }, list5_1= {1}, list5_2= {2 3 }, and the third List3= { info1, info2}, the second target beam corresponding to the mth element in List2 has the associated second configuration information of the mth element in the third List, specifically, for example, m =2, the 2 nd element in List2 is List5_2= {2 3 4}, that is, the configuration information of

Wherein the first element and the second element appear in the sixth list in no sequential order.

For another example, list6= { list7, info2}, where list7= {1,2}, the first element in the sixth list corresponds to the third target beam, and the associated third target configuration information is the second element in the sixth list, that is, the third target configuration information of the

third target beam

In the embodiment of the invention, the terminal can directly acquire the target information associated with the beam where the terminal is located, and execute cell reselection based on the target information, so that the terminal equipment can be prevented from performing unnecessary measurement, and the power consumption is avoided.

As shown in fig. 4, an embodiment of the present invention provides a method 400 for cell reselection, which may be performed by a terminal device, in other words, by software or hardware installed in the terminal device, and includes the following steps:

s402: the terminal obtains at least one target configuration information associated with the target beam.

The terminal may obtain one or more target configuration information. The target configuration information may include an association relationship between the beam information and the target configuration information. For example, the network device sends the association relationship between the beam information and the target configuration information to the terminal, and the terminal receives the association relationship.

Wherein, the incidence relation between the target beam and the target configuration information comprises one of the following:

associating a target beam with a target configuration information; for example, the target beams 0/1/2/3/4/5/6 all belong to one Cell, and the target beams 0/1/2/3/4/5/6 are respectively associated with one piece of target configuration information, which may be the same or different;

associating a plurality of target beams with a target configuration information; for example, the target beams 0/1/2/3/4/5/6 all belong to one Cell, the target beams 0/1/2/3 are respectively associated with one piece of target configuration information, and the target beams 4/5/6 are associated with another piece of target configuration information.

S404: and selecting target configuration information associated with the beam.

The terminal may select the target configuration information according to the beam where the terminal is located and the association relationship obtained in the previous step.

For example, the target beams 0/1/2/3/4/5/6 all belong to one Cell, the beam where the terminal is located is beam 1, and the beams 0/1/2/3/4/5/6 are respectively associated with target configuration information 0/1/2/3/4/5/6, so that the terminal selects the target configuration information 1; for another example, if the target beams 0/1/2/3 are respectively associated with the target configuration information 0, and the target beams 4/5/6 are associated with the target configuration information 1, the terminal selects the target configuration information 0.

The terminal may select a target configuration information behavior based on the located beam according to a protocol agreement. For example, the protocol provides that when the terminal receives a plurality of target configuration information related to a target beam broadcasted by the network, the terminal always selects one target configuration information related to the target beam based on the beam where the terminal is located.

Wherein the target configuration information includes at least one of:
