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.

說明書

When a subframe format is a format (b) and ns=0, details are as follows:

Calculation manners of identifiers bki of GF transmission sub-bands that can be used by a terminal 1 with an ID of 1 and a terminal with an ID of 2 are the same as those in the foregoing. Details are not described herein again.

In addition, when an identifier of a symbol meets ns=1, calculation of the identifiers bki of the GF transmission sub-bands that can be used by the terminal 1 and a terminal 2 is as follows:

When the identity ID nk of the terminal k meets nk=1, based on the foregoing formula (1), the following results are obtained.

An identifier of a sub-band corresponding to a first GF time-frequency resource of a terminal whose ID is 1 is as follows: b11=0·4+(1+1) mod 4=2.

An identifier of a sub-band corresponding to a second GF time-frequency resource of a terminal whose ID is 1 is as follows: b12=1·4+(1+1) mod 4=6.

An identifier of a sub-band corresponding to a third GF time-frequency resource of a terminal whose ID is 1 is as follows: b13=2·4+(1+1) mod 4=10.

When the identity ID nk of the terminal k meets nk=2, based on the foregoing distribution rule formula, the following results are obtained.

An identifier of a sub-band corresponding to a first GF time-frequency resource of a terminal whose ID is 2 is as follows: b21=0·4+(1+2) mod 4=3.

An identifier of a sub-band corresponding to a second GF time-frequency resource of a terminal whose ID is 2 is as follows: b22=1·4+(1+2) mod 4=7.
