Problems solved by technology

For the wireless broadband private network, the number of users is much smaller than that of the public network Long Term Evaluation (LTE). Therefore, if the Physical HARQ Indicator Channel (PHICH) in the LTE system is used to carry the corresponding uplink transmission HARQ ACK / NACK will occupy more physical resources

Abstract

The invention discloses a communication response signal transmission method, a base station and a terminal. The method comprises the following steps: the base station monitors an uplink channel, determines whether uplink information from the terminal is successfully received, and forms a communication response signal; the base station encodes the communication response signal according to a predetermined rule to obtain an encoded response signal; and the base station maps the coded response signal to a downlink control channel and issues the coded response signal to the terminal. In this way, the resource overhead can be saved.

Description

Technical field [0001] The present application relates to the field of wireless broadband cluster communication technology, and in particular to transmission methods, base stations and terminals of communication response signals. Background technique [0002] Unlike the public mobile communication network, some wireless private networks are typically applied to specific business scenarios, such as emergency processing on-site video backhauties, enforcement records of video return, public facilities data collection and video return. In these scenarios, a large amount of data needs to be transmitted from the user equipment (User Equipment, UE) to the base station, and from the base station to the UE, the control signaling and a small amount of information are mainly transmitted, so the uplink transmission data is much greater than the downlink data. [0003] For uplink transmission, it is necessary to use Hybrid Automatic RepetRequest (HARQ) technology to improve the transmission p...
