Method and terminal for selecting main carrier of carrier aggregation cell

Abstract

The invention provides a method for selecting a main carrier of a carrier aggregation cell, a terminal, computer equipment and a readable storage medium; the method comprises the steps: periodically reading, by the terminal, a current beam azimuth angle of an uplink service, and determining whether the current beam azimuth angle is in a critical state or not; if yes, starting to monitor other working frequency bands except the working frequency band except the current main carrier and the current auxiliary carrier so as to search candidate base stations which can be used; calculating a beam azimuth angle pointing to the candidate base station through a terminal array antenna; selecting an optimal service beam and a target base station according to the current beam azimuth angle of the uplink service and the beam azimuth angle pointing to the candidate base station; and residing in the target base station. According to the technical scheme disclosed by the invention, the dominant main carrier can be autonomously selected based on the self beam state sensing of the terminal, so that the optimal coverage and rate experience of the user can be obtained, and terminal service interruption caused by pilot frequency measurement when the base station initiates a complex pilot frequency switching process is avoided.

Description

technical field [0001] The disclosure belongs to the field of communication technologies, and in particular relates to a method for selecting a primary carrier of a carrier aggregation cell, a terminal, a computer device, and a computer-readable storage medium. Background technique [0002] Mobile spectrum is the core competitiveness of operators, and the use of spectrum resources is related to network construction costs and perceived network advantages (network coverage, capacity performance). In the long run, the commercial scale of 5G will ultimately depend on how the sub6G frequency band is planned and used. At present, the domestic sub6G mobile frequency band can be divided into three layers: the low frequency band below 1GHz, the medium frequency band from 1GHz to 3GHz, and the high frequency band from 3GHz to 6GHz. As we all know, the lower the frequency band, the better the coverage effect. However, the spectrum supply in the domestic low and medium frequency bands ...

Problems solved by technology

[0009] When the network configures multiple carriers as optional main carriers at the same time, the current technical mechanism is that the user terminal selects the initial carrier as the main carrier until the channel quality of the initial main carrier drops to the point where a complex inter-frequency cell handover operation is triggered , but it is impossible to select the optimal main carrier cell to reside in in real time as needed

In addition, the inter-frequency handover needs to make the UE temporarily interrupt the service and enter the measurement gap state before it can measure the inter-frequency adjacent cells, which will affect the user experience
