Description
Technical Field
The invention relates to the field of communication, in particular to an auxiliary carrier activation and deactivation method, a user terminal, a base station and a communication system in a carrier aggregation technology.
Background
A carrier aggregation technology is introduced into LTE-Advanced (Long Term Evolution-Advanced), and the requirement of an LTE-Advanced system on frequency band resources is solved through aggregation use of two or more basic carriers. In carrier aggregation, each UE (User Equipment) may be allocated to multiple CCs (component carriers) for larger data volume transmission. After the SCC (Secondary component carrier, hereinafter referred to as a Secondary carrier) is activated, the UE may send an SRS (Sounding Reference signal) on the SCell (Secondary Cell) according to the configuration, report a CQI/PMI/RI (Channel quality Indicator/Precoding Matrix Indicator, Precoding Matrix Indicator/rank Indicator, or rank Indicator), and monitor a PDCCH (Physical Downlink Control Channel) on the SCell. When the data volume of the UE is not large and the SCC is not needed, the UE still performs blind detection continuously, which consumes the power of the UE and reduces the efficiency. Currently, when activation and deactivation are performed, activation and deactivation determination are simply performed based on data volume per millisecond, and the data volume fluctuates due to signal quality deterioration in the moving process of the UE, so that multiple activation and deactivation processes are likely to occur in a short time, and since scheduling of the secondary carrier needs to be performed after ACK (acknowledgement) corresponding to a data packet of a MAC CE (Media Access Control Element) is fed back, too many activation and deactivation processes may affect the stability of the secondary carrier.
