Embodiment Construction

[0032] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0033] The inventor found in practice that the image interference problem caused by the power imbalance of adjacent component carriers mainly meets the following conditions:

[0034] 1. There are at least two or more component carriers close to the center carrier;

[0035] 2. There is a power imbalance on component carriers that exceeds a certain threshold. After a lot of experiments and simulations, it is generally considered that this threshold is 6dB is more appropriate. Of course, the smaller the threshold, the smaller the image interference.

[0036] Only when the above two conditions are met at the same time will there be serious system communication performance degradation. Otherwise, as long as the UE receiver meets the image suppression requirements specified in the standard, the image interference caused by...

Abstract

The disclosure discloses a radio resource control method and device, the radio resource control method includes that: a User Equipment (UE) detects the Reference Signal Receiving Power (RSRP) of each component carrier and determines whether or not a preset requirement for image interference due to power imbalance is met according to the result of the detection; and a preset image interference avoidance strategy is performed if the preset requirement for image interference due to power imbalance is met. The disclosure is capable of addressing the problem that the power imbalance between component carriers adjacent in frequency degrades communication performance.

Description

technical field [0001] The present invention relates to the carrier aggregation (CA, CarrierAggregation) technology in the enhanced long-term evolution (LTE-A, Long Term Evolution-Advanced), in particular to a radio resource control method and device. Background technique [0002] In order to meet the future peak rate requirements of the International Telecommunications Union (ITU, International Telecommunications Union), LTE-A currently supports a maximum bandwidth of 100MHz. However, it is difficult to find such a large bandwidth in the existing available spectrum resources, and large bandwidth is provided for base stations and terminals. The hardware design brings great difficulties. In addition, for spectrum resources scattered in multiple frequency bands, a technology is urgently needed to make full use of them. Based on the above considerations, LTE-A introduces the key technology of carrier aggregation. [0003] In carrier aggregation, the power imbalance between mu...
