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

Embodiments of the present invention provide a method and device for allocating uplink carrier resources in carrier aggregation, the method comprising: eNodeB determines the uplink carrier scheduled by each downlink carrier, allocates CA-dedicated semi-static resources to UE, and determines CA-dedicated semi-static resources Configuration information, the configuration information of CA dedicated semi-static resources is sent to UE through RRC dedicated signaling. Select a carrier among the carriers, and send the control channel scrambled by CRC with Special SPS C‑RNTI to the UE on the carrier, so that the UE can activate or deactivate the corresponding CA dedicated semi-static resources on the corresponding uplink carrier, and solve the simultaneous scheduling of a downlink carrier When there are multiple uplink carriers, the resources of the uplink carrier are not fully utilized due to the shortage of control channel resources on the downlink carrier.

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...
