Problems solved by technology

However, during the execution of the multi-carrier HSUPA technology, since there are multiple carriers available to the terminal, if the non-scheduled resources are configured using the single-carrier HSUPA non-scheduled resource configuration method, the terminal cannot know which carrier to transmit data and Monitor the response, the multi-carrier HSUPA service will not be executed correctly

Embodiment Construction

[0034]In the process of unscheduled transmission of single-carrier HSUPA technology, since there is only one available carrier for the terminal, the RNC does not need to indicate to the terminal the carriers where the E-PUCH channel and E-HICH channel are located; During the transmission process, considering that the number of carriers available to the terminal is more than one, the RNC needs to indicate the carrier where the E-PUCH channel used for uplink data transmission to the terminal is located when configuring non-scheduled resources, and the carrier that carries the E-PUCH channel transmission. The carrier where the E-HICH channel of the confirmation information corresponding to the data is located, the terminal determines the E-PUCH channel and the E-HICH channel according to the indicated carrier, and transmits data uplink through the determined E-PUCH channel, and transmits data through the determined E-HICH channel Channel monitoring confirmation message.

Abstract

The invention discloses a non-scheduling resource indication method in multi-carrier HSUPA. The method comprises the following steps that a radio network controller RNC determines the carrier identifications of all carriers the E-PUCHs (Enhanced-Physical Uplink Channels) of terminals belong to and determines the carrier identifications of all carriers the E-HICHs (E-DCH Hybrid ARQ Indicator Channels) of the terminals belong to; the radio network controller sends the carrier identification the E-PUCH of each terminal belongs to and the carrier identification the E-HICH of the terminal to the corresponding terminal by the received carrier identifications to indicate the terminal to determine the carrier of the E-PUCH and the carrier of the E-HICH. The defect of insufficient non-scheduling resources in a single-carrier HSUPA technology is solved by the invention. The invention also provides a non-scheduling resource indication system, a wireless network controller and a terminal in the multi-carrier HSUPA.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method system for indicating non-scheduled resources in multi-carrier HSUPA technology, a wireless network controller and a terminal. Background technique [0002] In order to improve the uplink data transmission capability, Wideband Code Division Multiple Access (WCDMA) medium frequency division duplex (Frequency Division Duplex, FDD) mode, high chip rate time division duplex (High Chip Rate Time Division Duplex, HCR TDD) mode The uplink enhancement ( Enhanced Uplink) technology, called High Speed ​​Uplink Packet Access (HSUPA) technology. [0003] HSUPA uses key technologies such as Hybrid Automatic Repeat Request (HARQ), adaptive modulation and coding (Adaptive Modulation and Code, AMC) and fast scheduling, so that data transmission can quickly adapt to channel changes, thereby reducing retransmission delay, improve link performance, and improve system throughput.
