Embodiment Construction

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. It can be understood that, on the premise that there is no ambiguity or contradiction, other embodiments obtained by those skilled in the art by combining the technical features in the embodiments or between the embodiments also belong to the protection scope of the present invention.

[0047] The technical scheme that the embodiment of the present invention proposes is based on such as figure 1 A communication system 100 is shown. The communication system 100 can support uplink contention transmission mode. The communication system 100 includes at least one base station (base station, BS) and at least two terminal devices. In the uplink contention transmission mode, the base station allocates an...

Abstract

The invention discloses a communication method, apparatus and system. The communication method comprises the following steps: a base station receives uplink data sent by a terminal device, and performs decoding on the uplink data; and the base station sends feedback information of the uplink data, wherein the feedback information is used for indicating a decoding condition of the uplink data, thefeedback information carries information of an identifier, and the identifier includes an identity identifier of the terminal device or an identifier of the uplink data. Therefore, the terminal deviceis prevented from receiving false feedback information in conflict transmission.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a communication method, device and system. Background technique [0002] In the wireless communication field, especially in the cellular mobile communication network, the uplink data transmission from the terminal equipment to the base station may adopt a contention-based uplink transmission mode. The terminal device selects available uplink resources from the pre-allocated uplink resource pool, and transmits data to the base station. After receiving the uplink data sent by the terminal device, the base station needs to feed back response information to the terminal device to notify the terminal device whether the transmitted data has been received correctly. [0003] The base station determines the position of the downlink resource used by the terminal device to feed back the response information according to the position of the uplink resource used by the ter...
