Embodiment Construction

[0024] The basic idea of ​​this paper is to define the operation of user equipment (UE) and network to implement PUCCH reconfiguration in R13. In this paper, the following contents are mainly proposed:

[0025] 1. Five schemes for implementing reconfiguration of Scell_PUCCH.

[0026] 2. Various schemes for handling the operation of the old Scell_PUCCH, including its uplink synchronization (UL SYN) state, activation / deactivation state.

[0027] 3. Various schemes for handling the operation of the new Scell_PUCCH, including its uplink synchronization (UL SYN) state and activation / deactivation state.

[0028] 4. Various schemes for handling the operation of the associated Scell ​​after the completion of the reconfiguration process.

[0029] As mentioned above, in the topic of enhanced carrier aggregation in R13, 3GPP must discuss how to deal with the issues related to the reconfiguration of Scell_PUCCH. For this scenario, the following three types of Scells will be affected du...

Abstract

The invention relates to a method for configuring secondary cells provided with PUCCH (Physical Uplink Control Channel) resources in a communication system based on carrier aggregation. The method both solves a problem of reconfiguration of a Scell-PUCCH and processing modes for an uplink synchronization state and an activated / deactivated state of various types of Scells after reconfiguration of the Scell-PUCCH.

Description

technical field [0001] The present invention relates to a communication system, and more specifically, to a method for configuring a secondary cell with PUCCH resources in a communication system based on carrier aggregation. Background technique [0002] Research on R13 carrier aggregation enhancements is ongoing in RAN 1 and RAN 2. The main feature is that: PUCCH transmission is supported on the secondary cell (Scell). Moreover, as known in the prior art, in a carrier aggregation communication system, there is one base station, which may be configured with multiple cells. Among them, there is one primary cell (Pcell) and zero or at least one Scell. [0003] In this paper, for the convenience of explanation, the following definition is made: the Scell ​​configured with PUCCH resources is called Scell_PUCCH. These PUCCH resources can be used for transmission of Scell_PUCCH and uplink control information of other Scells. Here, the Scell ​​whose uplink control information t...
