Embodiment Construction

[0064] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0065] The method for configuring an uplink carrier in carrier aggregation provided by an embodiment of the present invention is applicable to a carrier aggregation scenario where there are more uplink carriers than downlink carriers.

[0066] In this embodiment, when determining that the carrier switching condition of the terminal device is satis...

Abstract

The embodiment of the invention discloses an uplink carrier configuration method and a device in carrier aggregation, and a base station. The method comprises the following steps: a source base station judges whether a carrier switching condition of terminal equipment is met or not; and if yes, the source base station sends a radio resource control (RRC) connection reconfiguration message to the terminal equipment, so that the terminal device sends data on one target uplink carrier in at least one first uplink carrier indicated by the RRC connection reconfiguration message, wherein the RRC connection reconfiguration message comprises information of the at least one first uplink carrier, the first uplink carrier is an uplink carrier except an uplink carrier pre-paired with a downlink carrier, and thus switching of the uplink carrier is realized.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method, device and base station for configuring uplink carriers in carrier aggregation. Background technique [0002] In order to meet the requirements of single-user peak rate and system capacity improvement, one of the most direct methods is to increase the system transmission bandwidth. Therefore, the Long Term Evolution Advanced (LTE-Advanced for short) system introduces a technology for increasing transmission bandwidth, that is, CA (Carrier Aggregation, carrier aggregation). In some industrial network applications, there will be situations where the demand for uplink services is greater than that for downlink services. Therefore, in order to better meet the needs of a large number of uplink services, an asymmetric uplink carrier aggregation technology is proposed in which the number of uplink carriers is greater than the number of do...
