Method, device, user equipment and network side equipment for multi-carrier aggregation

Abstract

A multi-carrier aggregation method and apparatus, user equipment, and a network side device are disclosed. The method includes: determining, by a network side device according to information about a transmission resource that is obtained when at least one component carrier is successfully obtained through contention, start and end times of a scheduling phase corresponding to the at least one component carrier, where the scheduling phase is divided by an uplink-downlink switch point into an uplink phase of the scheduling phase and a downlink phase of the scheduling phase, the uplink-downlink switch point is used to divide a time to obtain an uplink time of the component carrier and a downlink time of the component carrier, and uplink-downlink switch points of two or more component carriers are aligned in time; and performing, by the network side device, downlink transmission with user equipment in the downlink phase of the scheduling phase, and performing, by the network side device, uplink transmission with the user equipment in the uplink phase of the scheduling phase. Embodiments of the present invention can improve a utilization rate of each component carrier.

Description

technical field [0001] The present invention relates to the communication field, and in particular to a multi-carrier aggregation method, device, user equipment (STA) and network side equipment. Background technique [0002] More and more application scenarios and increasing data transmission requirements make the load on the wireless network heavier and heavier. Wireless networks are improved and upgraded from many technical aspects, and the simplest and most direct way among these technologies is to increase spectrum resources. For the spectrum that is strictly controlled by the spectrum management agency, it is difficult to continuously distribute the spectrum obtained by purchasing licenses, and it is necessary to use the technology of spectrum resource fragmentation to increase the peak rate of data transmission. For free spectrum, wireless devices can be used as long as they meet the power limit. However, data transmission in wireless communication usually requires a ...
