摘要

This application provides an uplink transmission method, a terminal, and a network side device. The method includes: storing, by a terminal, an uplink transmission time-frequency resource allocated by a network side device; when the terminal needs to send an uplink signal, determining the to-be-transmitted uplink signal based on a quantity of orthogonal frequency division multiplexing (OFDM) symbols in the uplink transmission time-frequency resource; and sending, by the terminal, the uplink signal to the network side device. During implementation of the uplink transmission method provided in this application, grant free transmission solutions are provided for different uplink transmission time-frequency resources, to effectively improve communication performance.

說(shuō)明書

According to another aspect, an embodiment provides a base station, where the base station has a function of implementing base station behavior in the foregoing method design. The function may be implemented by using hardware, or may be implemented by executing corresponding software by hardware. The hardware or software includes one or more modules corresponding to the foregoing function.

In one design, a structure of the base station includes a processor and a transceiver, where the processor is configured to support the base station in performing corresponding functions in the foregoing method. The transceiver is configured to support communication between the base station and the terminal, send information or signaling used in the foregoing method to the terminal, and receive information or an instruction sent by the base station. The base station may further include a memory, and the memory is configured to couple to the processor and store a program instruction and data that are necessary for the base station.

According to still another aspect, an embodiment provides a control node that may include a controller/processor, a memory, and a communications unit. The controller/processor may be configured to coordinate resource management and configuration between a plurality of base stations, and may be configured to perform the method for configuring a time-frequency resource for the terminal that is described in the foregoing embodiment. The memory may be configured to store program code and data of the control node. The communications unit is configured to support communication between the control node and the base station, for example, send information about a configured resource to the base station.

According to yet another aspect, an embodiment provides a communications chip, and the communications chip includes:
