Problems solved by technology

[0003] When performing the initial receive beam scan, the UE obtains multiple cells by scanning multiple beams. If the acquired multiple cells are only sequentially decoded according to the existing cell residence process, the physical broadcast channel (Physical Broadcast Channel, PBCH) and the remaining minimum system information (Remaining Minimum System Information, RMSI) to select a suitable cell to reside on, it may waste time on some cells with signal fluctuations or instability, which increases the cell residency delay and reduces the success rate of cell residency , therefore, how to achieve fast and accurate cell residency becomes a problem

Embodiment Construction

[0048] The terms "first", "second" and the like in the description, embodiments and claims of the present application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence. Furthermore, the terms "comprising" and "having", as well as any variations thereof, are intended to cover a non-exclusive inclusion, for example, of a sequence of steps or elements. A method, system, product or device is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to the process, method, product or device.

[0049] It should be understood that in this application, "at least one" means one or more, and "multiple" means two or more. "And / or" is used to describe the association relationship of associated objects, indicating that there can be three types of relationships, for example, "A and / or B" can mean: only A exists, only B e...

Abstract

The embodiment of the invention discloses a method and a device for selecting resident cells. The method comprises the following steps of: selecting N cells to be resided from a candidate cell list; decoding a physical broadcast channel PBCH for each of the selected N cells to be resided; selecting one cell to continue to reside from the at least one cell which is successfully decoded by the PBCH;and when the RMSI decoding result of the cell to be resided continuously indicates that the cell to be resided continuously meets a residence criterion, determining the cell to be resided continuously as the resident cell. The scheme disclosed by the embodiment of the invention is convenient for improving the success rate of cell residence and reducing the cell residence time delay.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and device for selecting a cell to reside on. Background technique [0002] In the fifth-generation (fifth-generation, 5G) communication technology, the application of spectrum resources in high frequency bands has become an effective way to realize high data rate communication. However, due to the wireless propagation characteristics of high-frequency bands, 5G high-frequency signal attenuation is serious. In order to effectively increase signal coverage and overcome path attenuation in high-frequency bands, 5G introduces multi-beam communication technology. Both base stations and user equipment (User Equipment, UE) have There are multiple beams with different directions, but the signal gain is the strongest only in a specific direction. Therefore, when the UE camps in a cell at a high frequency point, it will generally try multiple receiving beams, that is, thro...
