Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] In order to solve the problem that some UEs cannot configure PUCCH resources in the PUCCH resource configuration method in the prior art and the secondary carrier activation process is lengthy, in the embodiment of the present invention, after the base station instructs each UE within the jurisdiction to perform secondary carrier measurement, based on Based on the secondary carrier measurement results reported by the UE, determine the sec...

Abstract

The invention discloses a configuration method and a configuration device for PUCCH resources under carrier aggregation, which are used for solving the problems that according to a configuration method for PUCCH resources in the prior art, part of UE (User Equipment) cannot configure the PUCCH resources and the process of activating a non-main carrier is tedious. The method comprises the steps that: after determining non-main carrier signal intensity obtained by each of UE in an administering range of a base station, the base station screens out M pieces of UE; corresponding special PUCCH resources are respectively configured to each of the M pieces of UE; and a public PUCCH resource is configured to other UE except for the M pieces of UE. Therefore, not only can each UE be guaranteed to timely acquire the special PUCCH resource when the number of the UE is small, but also due to existence of reservation of the PUCCH resources, the UE sharing one public PUCCH resource also can be guaranteed to timely acquire the special PUCCH resources.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for configuring PUCCH resources under carrier aggregation. Background technique [0002] In a long term evolution system (Long Term Evolution, LTE), a carrier aggregation (CarrierAggregation, CA) technology is generally used to increase a data download rate and a data upload rate of a user equipment (User Equipment, UE). When the UE selects a cell to access or camp on, it usually selects a cell with a high frequency priority to access or camp on, so there will be a large number of UEs accessing or camping on the same cell with a high frequency priority. Moreover, in the process of carrier aggregation, it is necessary to use the PUCCH resources in the above-mentioned high-frequency priority cell (hereinafter referred to as the above-mentioned high-frequency priority cell as the primary cell) to perform Hybrid Automatic Repeat reQuest (HAR...
