Indicating and feedback method, system and apparatus of uplink control channel in multi-carrier wave system

Abstract

The invention discloses an indicating method of an uplink control channel in a multi-carrier wave system. The method comprises the steps as follows: a network side distributes the one-to-one uplink control channel for downlink carrier wave occupied by a terminal; the network side sends the corresponding relation of the uplink control channel and a downlink control channel distributed for each terminal to the corresponding terminal and indicates the terminal to determine the uplink control channel of feedback information carrying continuous scheduling data according to the corresponding relation of the uplink control channel and the downlink control channel when the continuous scheduling data are received through the downlink carrier wave. Through the invention, the terminal can determine the uplink control channel which transmits the feedback information corresponding to the continuous scheduling data to the network side through the corresponding relation of the uplink control channelindicated by the network side and the downlink carrier wave occupied by the terminal. The invention also discloses a method, a network side apparatus, a terminal and a communication system for transmitting the feedback information.

Description

technical field [0001] The present invention relates to the communication field, in particular to an indication method of an uplink control channel in a multi-carrier system, a method, a system and a device for a terminal to transmit feedback information through an uplink control channel. Background technique [0002] With the development of communication systems, the requirements for the quantity and rate of data transmission are getting higher and higher. Therefore, based on the long term evolution standard (Long term evaluation, LTE), an evolved version of LTE, the LTE-A system, is proposed. The LTE-A system will support a larger bandwidth than the LTE system (the carrier bandwidth of the LTE system is 20MHz, and the bandwidth of the LTE-A system can reach 100MHz). In order to meet the bandwidth requirements of the LTE-A system, there are two possible Method to realize. A possible implementation is directly to allocate 100MHz spectrum for LTE-A system, such as figure 1 ...

AI Technical Summary

Problems solved by technology

However, in the LTE-A system, since the terminal can occupy multiple downlink carriers for data transmission at the same time, and the feedback information of the persistent scheduling data transmitted by each downlink carrier needs to be transmitted through an uplink feedback channel respectively, therefore, the network in the LTE system The method of configuring the uplink feedback channel for the terminal on the side cannot be applied to the LTE-A system, and it is urgent to find an uplink feedback method for aggregated carriers
