Description
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to a method and a device for uplink scheduling in asymmetric carrier aggregation.
Background
In the current LTE system, a single carrier supports a system bandwidth of 20M at maximum, and if a larger bandwidth is to be supported, a carrier aggregation technique needs to be adopted.
In the 3GPP protocol, aggregation of a maximum of 5 carriers is supported, but the number of downlink carriers is required to be greater than or equal to the number of uplink carriers. In a public network operator network, the downlink service requirement is usually greater than the uplink service requirement, and the carrier aggregation defined by 3GPP can better meet the requirements of the operator network. However, in some industry network applications, there are a large number of video monitoring services, and at this time, the uplink service requirement is greater than the downlink service requirement, and in this case, the carrier aggregation scheme defined by 3GPP cannot well meet the requirements of the industry network.
In order to better satisfy a large number of uplink service demand scenarios, an asymmetric carrier aggregation technology in which the number of uplink carriers is greater than the number of downlink carriers needs to be introduced. However, how to perform uplink scheduling in such a scenario can only satisfy a large amount of uplink service requirements is an urgent technical problem to be solved.
