Problems solved by technology

Therefore, after multiple rounds of reselection, most UEs will camp on cells with a large number of beams (such as mainly camping on figure 1 12), resulting in a high load on cells with a large number of beams in the network (in general, high-frequency cells have a large number of beams), and a low load on cells with a small number of beams
[0006] Therefore, based on the existing cell reselection logic, it will lead to the problem of unbalanced load among cells in the network, which will seriously affect the quality of UE camping.

Embodiment Construction

[0050] Those skilled in the art understand that, as mentioned in the background, based on the provisions of existing protocols, when user equipment (User Equipment, UE for short) in the network performs cell reselection, after multiple rounds of reselection, most UEs tend to Camping in a cell with a large number of beams (beams) causes the cells in the network to finally show a phenomenon of uneven load.

[0051] The inventor of the present application finds through analysis that this is because the prior art does not consider the impact of the difference in the number of beams of different cells on the cell reselection result of the UE.

[0052] Specifically, a UE that performs cell reselection according to the prior art will select a cell with more good beams (good beams) to camp on. For a cell with a large number of beams, there is a high probability that the number of excellent beams determined by measurement of this type of cell will also be large, so the probability of t...

Abstract

A cell reselection method and device, a storage medium, and a terminal, the method comprising: for each candidate cell in a set of candidate cells, performing normalization processing on the number of excellent beams of the candidate cell; The number of excellent beams after normalization is used to select the preferred cell. The solution provided by the invention can effectively balance the load of each cell in the network, so that the distribution of UEs residing in the network is more reasonable.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a cell reselection method and device, a storage medium, and a terminal. Background technique [0002] With the development of the Fifth-Generation mobile communications (5G for short), a concept of multi-beam (beam) has been introduced into a New Radio (NR, NR for short, also called New Radio) system. [0003] Specifically, in 5G NR, a cell (cell) is composed of multiple beams, and each beam broadcasts a Synchronization Signal Block (SS BLOCK for short, that is, SSB), and the SSB has an SSB index (SSBINDEX ), the user equipment (User Equipment, UE for short) performs downlink synchronization by receiving the SSB. [0004] A UE in an idle state (IDLE) needs to monitor the signals of the serving cell and neighboring cells, and select the best serving cell to reside in according to certain rules. [0005] According to the provisions of the existing protocol, i...
