Problems solved by technology

Since the base station does not know the identification information of the user equipment in the unlicensed transmission mode, nor does it know the time-frequency resource information occupied by the user equipment for data transmission, the base station cannot use the feedback method in the prior art to feedback the data transmission of the user equipment
However, if the user ID is directly fed back to the user equipment that has successfully decoded to indicate that the transmission is successful, the number of bits occupied by the user ID is too long, which will reduce the efficiency of resource usage.

Abstract

The invention discloses an authorization-free transmission method, network equipment, and terminal equipment. The method comprises the steps that the network equipment detects a pilot frequency sequence used by the terminal equipment for uplink transmission; the network equipment determines a pilot frequency sequence index of the pilot frequency sequence according to the pilot frequency sequence and the corresponding relation between the pilot frequency sequence and the pilot frequency sequence index; the network equipment transmits the information of a feedback result of uplink transmission to the terminal equipment according to the pilot frequency sequence index. Therefore, the network equipment indicates the feedback result of the current uplink transmission for the terminal equipment through the pilot frequency sequence index, and can achieve the feedback of the authorization-free transmission of user equipment through the effective use of a wireless transmission resource.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, network equipment and terminal equipment for authorization-free transmission in the communication field. Background technique [0002] In a typical wireless communication network (for example, a Long Term Evolution (LTE) network for short), the selection of uplink data shared channels (Shared Data Channels) is based on a scheduling / grant (Scheduling / Grant) mechanism, which is completely determined by the base station ( Base Station, referred to as "BS") control, the complete data transmission process usually includes four steps: scheduling request, scheduling grant, data transmission, transmission feedback. In this mechanism, the user equipment (UserEquipment, referred to as "UE") First send an uplink scheduling request to the BS. After receiving the request, the BS sends an uplink Grant to the UE to notify the UE of the uplink transmission resources allocated to the U...
