Embodiment Construction

[0032] The core of the present invention is to provide a base station that can support multi-carrier operation, where each carrier can be configured with a certain number of high-speed uplink packet access channels according to network planning or service requirements. During data transmission, the base station measures the interference on each carrier, and uses the obtained interference measurement value to sort the carriers. When allocating resources, the wireless resources are allocated on the carrier with the smaller interference measurement value first. , the specific resource allocation method is determined in combination with the configuration of the high-speed downlink packet access channel on the carrier.

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Abstract

The invention discloses a wireless resource distribution method for a high-speed packet access system which comprises a base station supporting multi-carrier transmission and a terminal supporting at least one carrier transmission ability, wherein the base station is the wireless resource that is necessary in distribution uplink transmission direction to the terminal having wireless connection with the base station, the method comprises the steps of: determining the quantity of the uplink wireless resources as required by the terminal; distributing the uplink wireless resources for the terminal in accordance with interference value of each carrier that is prearranged with a high-speed packet access channel. The invention also provides a device for wireless resource distribution for the high-speed packet access system. In sufficient consideration of interference situation of each carrier and situation of channel configuration, the invention rationalizes resource distribution, optimizes transmission efficiency and is able to reduce complexity of system realization.

Description

technical field [0001] The present invention relates to the resource allocation technology in the mobile communication system, especially the wireless resource allocation method and its device in the multi-carrier system configured with high-speed packet access channel. Background technique [0002] In order to improve the uplink data transmission capability, frequency division duplex (FDD, Frequency Division Duplex) mode and time division duplex (HCR TDD, High ChipRate Time Division Duplex) mode in wideband code division multiple access system (WCDMA), as well as time division synchronization Code division multiple access system (TD-SCDMA, also known as low chip rate TDD mode, LCR TDD) successively introduced enhanced uplink (EnhancedUplink) technology in Release 6 and Release 7 defined by the third generation mobile communication standardization organization , called HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access) technology. [0003] The key ...
