Problems solved by technology

[0010] The present invention provides a feedback channel allocation indication method and system to solve the problem that in the downlink direction of LTE technology, when a base station uses the same scheduling channel to schedule multiple terminals at the same time, multiple terminals may use the same feedback channel at the same time. The channel sends feedback information to the base station, and in the existing HSUPA technology, when the feedback information of multiple terminals is multiplexed into one feedback channel for transmission, the implementation complexity of the base station and the terminal is relatively high

Embodiment Construction

[0075] The technical solution of the present invention carries the indication information of the feedback channel allocated to the terminal on the scheduling channel, so that the terminal can know the resource position occupied by the feedback channel allocated to it, thereby solving the problem of the existing LTE or HSUPA technology when the network side is at the same time. When one TTI uses the same scheduling channel to schedule multiple terminals, the feedback channel conflict problem may occur.

[0076] The main realization principles, specific implementation methods and corresponding beneficial effects of the technical solution of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0077] Please refer to Fig. 1, which is a flow chart of the present invention for the feedback channel allocation indication method in the downlink direction in LTE technology, and its main implementation process is:

Abstract

The invention discloses an instructional method and system to allocate the feedback channels, which can facilitate a terminal to know the position of the resources occupied by the feedback channels allocated to the terminal through carrying the instructional information of the feedback channels allocated to the terminal in the dispatching channels, thereby solving the problem that in the down direction of the current LTE technique, when the base station dispatches a plurality of terminals by using the same dispatching channel at the same time, a plurality of terminals send the feedback information by using the same dispatching channel at the same time to the base station and the problem that in the current HSUPA technique, when the feedback information of a plurality of channels is transmitted by copying to a feedback channel, the complexity of realizing the base station and the terminal is high.

Description

technical field [0001] The invention relates to the communication field, in particular to a feedback channel allocation indication method and system. Background technique [0002] In order to improve the user's peak data transmission rate and system throughput, the third-generation mobile communication system introduced HSDPA (High Speed ​​Downlink Packet Access) technology in the R5 protocol, and introduced HSUPA in the R6 protocol. (High Speed ​​Uplink PacketAccess, high-speed uplink packet access) technology, respectively used for uplink transmission enhancement and downlink transmission enhancement. [0003] HSDPA technology and HSUPA technology have similar working principles and key technologies, such as AMC (Adaptive Modulation and Coding, adaptive modulation and coding), HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat request) and fast Scheduling and other technologies. In both HSDPA technology and HSUPA technology, the base station allocates resourc...
