Problems solved by technology

Especially in the carrier aggregation scenario, RRC connection reconfiguration will be more frequent than in the single carrier scenario, and the probability of configuration failure of Scell ​​configuration parameters will also increase, which will increase the number of RRC connection re-establishments, thereby affecting the normal data of the UE. transmission

Abstract

The embodiment of the invention discloses a radio resource control reconfiguration processing method and user equipment and belongs to the technical field of communication. The method comprises the following steps of: according to the indication of a RRC (radio resource control) connection reconfiguration message, carrying out RRC connection reconfiguration on a primary cell Pcell and / or a secondary cell Scell; if the Pcell configuration is failed or the parameter configuration of the Pcell is failed, executing RRC connection reestablishment; and if the Scell configuration is failed or the parameter configuration of the Scell is failed, reporting the base station that the Scell configuration or the parameter configuration is failed. By the adoption of the technical scheme, the times of RRC connection reestablishment caused by failure of RRC connection reconfiguration can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a radio resource control reconfiguration processing method and user equipment. Background technique [0002] In order to meet the requirements of IMT-Advanced (Advanced International Mobile Communications) and support a peak data rate of up to 1Gbits / s, the 3GPP LTE-ADVANCED (LTE-A, continued evolution of LTE) system has now agreed to integrate Carrier Aggregation (CA, Carrier Aggregation , also known as carrier aggregation) technology as a method to expand the system bandwidth. The carrier aggregation technology aggregates multiple component carriers (CC, Component Carrier) into a carrier with a larger bandwidth (for example, higher than 20 MHz), so as to support high-speed data transmission rate. For example, five component carriers of 20 MHz can be aggregated together to form a downlink transmission bandwidth of 100 MHz. [0003] In LTE-A technology, the cell ...
