Problems solved by technology

However, in sTTI transmission, the overhead necessary for communication such as reference signals or control channels has a non-negligible impact on TBS determination. The TBS determination method using the above-mentioned TTI less than 1ms will affect the reliability, accuracy and flexibility of communication, thus affecting User experience and system performance

Embodiment Construction

[0080] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0081] The terms "component", "module", "system" and the like are used in this specification to refer to a computer-related entity, hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and / or a computer. By way of illustration, both an application running on a computing device and the computing device can be components. One or more components can reside within a process and / or thread of execution and a component can be localized on one computer and / or distributed between two or more computers. In addition, these components can execute from various computer readable me...

Abstract

A method for wireless communication is provided, the method includes: a terminal device determines a first coefficient, the first coefficient belongs to a first coefficient set corresponding to a first transmission time interval TTI, the first coefficient set includes N coefficients, N ≥2, the N coefficients include at least two coefficients used for the uplink transmission of the first TTI, or the N coefficients include at least two coefficients used for the downlink transmission of the first TTI; the terminal device according to The first coefficient determines a first transmission block size TBS; the terminal device performs wireless communication through the first TTI according to the first TBS, which can improve reliability and accuracy of wireless communication.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication, and more specifically, to a method and device for wireless communication. Background technique [0002] At present, a wireless communication technology is known. If a data packet is transmitted on a TTI of 1 ms, usually the network device is determining the time-frequency resource used to transmit the data (or in other words, the time-frequency resource that the network device schedules or allocates to the terminal device) For example, after one or more resource blocks (Resource Block, referred to as "RB"), the network device based on the channel condition of the terminal device, from the transmission block size (Transport Block Size, referred to as "TBS") table and Select a TBS suitable for transmission by the terminal device from multiple TBS values ​​corresponding to frequency resources, and notify the terminal device of the Modulation and Coding Scheme (MCS for short) index ...
