The invention also discloses a corresponding sthe position of the terminal response channel by the index of the response channel and the positions of time-frequency resource of all response channels. The invention also discloses a corresponding system, a base station and a terminal for assigning the response channel. By applying the invention, the dimension of broadcast messages can be reduced when the resource is assigned, and the communicatystem, a base station and a terminal for assigning the response channel. By applying the invention, the dimension of broadcast messages can be reduced when the resource is assigned, and the communication overhead and the interference to the neighborhood can also be reduced.ion overhead and the interference to the neighborhood can also be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for assigning an acknowledgment (ACK, Acknowledgment) channel. Background technique [0002] Generally, a wireless communication system includes: a base station (BS, Base Station) and a terminal (MS, MobileStation). [0003] The BS and MS communicate through the air link. There is a BS-controlled communication method, that is, the BS assigns certain resources to the MS, and the MS analyzes the corresponding downlink data or sends the corresponding uplink data according to the resources assigned by the BS. data. Here, the downlink refers to the direction that the BS sends to the MS, and the uplink refers to the direction that the MS sends to the BS. [0004] In an Orthogonal Frequency Division Multiple Access (OFDMA, Orthogonal Frequency Division Multiplex Access) system, an Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal F...

AI Technical Summary

Problems solved by technology

[0017] Use the BS broadcast method to assign all MS resources. The broadcast content includes all assignment information. In order to consider the users with the worst channel environment, the broadcast message needs to use a low-order modulation and coding method, which makes the overhead too large.
