Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0045] The core idea of ​​the present invention is to clarify how to trigger the reporting process of SI according to the carrier state when there are multiple different carrier states on the UE side. Specifically, the SI reporting process can be triggered independently according to the status of each carrier allocated to the UE by the network side (hereinafter referred to as "carriers allocated by the network side to the UE" as "available carriers of the UE") independently, or all carriers can be The SI reporting process is triggered when the status meets the preset conditions. The present invention monitors the state of the carrier by setting a timer. If the SI reporting process is independently triggered according to the state of each carrier, a firs...

Abstract

The embodiment of the invention discloses a method and a device for triggering the reporting of scheduling information (SI) in a multi-carrier system. The method comprises the following steps of: respectively arranging a first timer corresponding to each carrier in the multi-carrier system, when the state of any carrier meets the preset condition, starting or restarting the first timer corresponding to the carrier, and if the first timer is overtime, triggering the reporting process of the SI; or arranging a second timer corresponding to all carriers, when the state of any carrier meets the preset condition, starting or restarting the second timer, and if the second timer is overtime, triggering the reporting process of the SI. The device comprises a trigger module in the reporting process of the SI and more than two first timers or one second timer. Under the condition of a plurality of different carrier states, the reporting process of the SI is triggered according to the carrier state; and through the technical scheme, the reporting process of the SI can be triggered in the multi-carrier system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for triggering scheduling information (SI) reporting in a multi-carrier system. Background technique [0002] In 2007, the seventh version of the third generation mobile communication system (3GPP Release 7) communication standard introduced the N frequency point feature for the High Speed ​​Uplink Packet Access (HSUPA) system, that is, in the HSUPA system , a cell has multiple frequency points, one of which is the primary frequency point, and the other frequency points are secondary frequency points. At present, in the HSUPA system that introduces the multi-frequency point feature, the UE works in single carrier mode, and the operating frequency point of the UE can be the main frequency point of the cell where the UE is located, or the secondary frequency point of the cell where the UE is located. [0003] The introduction of the N frequ...
