Problems solved by technology

However, in a real communication environment, it is difficult to adapt to the scene of rapid wireless signal changes based on prior information to determine the strength of the frequency point signal
When the signal changes rapidly, the UE may experience problems such as increased call drop rate, or even disconnected from the network

Embodiment Construction

[0027] Those skilled in the art understand that, as far as the background technology is concerned, the existing technical solutions either need to interrupt downlink reception and sacrifice the quality of downlink data reception; In this scenario, call drop or disconnection may occur.

[0028] The applicant of the present invention has found through research that the 3GPP protocol stipulates that the measurement gap cycle allocated by the network is generally 40 ms or 80 ms. Each measurement interval lasts 6ms, and a frequency point is measured. Taking LTE CA as an example, the network can configure up to 16 different frequency points. When the network configures 2G and 3G frequency point measurement for the UE, the cycle of inter-frequency measurement and reporting will be very long. The 3GPP agreement also stipulates that the longest measurement reporting cycle of 2G and 3G can be: N freq ×T meas ms. Among them, N freq is the number of frequency points of different fr...

Abstract

The invention discloses a different frequency measurement method and device based on carrier aggregation, a storage medium and a terminal. The different frequency measurement method comprises the following steps: determining a to-be-measured pilot frequency point; and measuring the pilot frequency point by using the main carrier wave and the auxiliary carrier wave. Through the technical scheme provided by the invention, the pilot frequency measurement times can be increased, and the pilot frequency measurement accuracy is improved, so that the mobile performance of the user equipment is enhanced, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a carrier aggregation-based inter-frequency measurement method and device, a storage medium, and a terminal. Background technique [0002] In the Long Term Evaluation (LTE for short) system, after the user equipment (User Equipment, UE for short) resides in the cell, the UE will start co-frequency, inter-frequency measurement within the LTE system and inter-system inter-frequency measurement according to the network configuration. The measurement is, for example, the inter-frequency measurement of the 2nd-Generation mobile communications (2G for short) frequency points and the 3rd-Generation mobile communications (3G for short) frequency points. The 3rd Generation Partnership Project (the 3rd Generation Partnership Project, referred to as 3GPP) agreement requires that the UE cannot interrupt the downlink reception to complete the inter-frequency measurement or the he...
