Embodiment Construction

[0057] 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.

[0058] In the LTE system, there are the following two typical carrier aggregation scenarios. Scenario 1 is mainly applied to scenarios where downlink service requirements are greater than or equal to uplink service requirements, and scenario 2 is mainly applied to scenarios where uplink service requirements are greater than downlink service requir...

Abstract

The embodiment of the invention provides a method and equipment for allocating uplink carrier resources in carrier aggregation. The method comprises the following steps: by the eNodeB, determining anuplink carrier scheduled by each downlink carrier; allocating CA dedicated semi-static resources to the UE; determining configuration information of CA dedicated semi-static resources; sending the configuration information of the CA dedicated semi-static resource to the UE through the RRC dedicated signaling; when determining to activate or deactivate a certain CA dedicated semi-static resource ona certain uplink carrier, selecting one carrier from the determined downlink carriers for scheduling the uplink carrier; and sending a control channel scrambled by the special SPS C-RNTI for the CRCto the UE on the carrier. Thus, the UE activates or deactivates the semi-static resources special for the corresponding CA on the corresponding uplink carrier, and the problem that when one downlink carrier schedules a plurality of uplink carriers at the same time, the resources of the uplink carriers are not fully utilized due to the fact that control channel resources on the downlink carrier arein shortage is solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for allocating uplink carrier resources in carrier aggregation. Background technique [0002] In a Long Term Evolution (LTE for short) system, there are the following two typical carrier aggregation scenarios. Scenario 1 is mainly applied to scenarios where downlink service requirements are greater than or equal to uplink service requirements, and scenario 2 is mainly applied to scenarios where uplink service requirements are greater than downlink service requirements. [0003] Scenario 1: The number of downlink component carriers is greater than or equal to the number of uplink component carriers; [0004] Scenario 2: The number of uplink component carriers is greater than the number of downlink component carriers; [0005] In the second scenario above, a downlink carrier may simultaneously schedule multiple uplink carrie...
