Embodiment Construction

[0071] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0072] The technical solutions provided in this disclosure are applicable to new-generation networks, such as 5G networks. In order to better support services that require high reliability and low latency, the NR system supports non-uplink grant free (ULGF for short) In the data transmission scheme, the user equipment can use semi-statically allocated periodic transmission time-frequency resourc...

Abstract

The present disclosure relates to a data transmission method, an apparatus, and a data transmitting end. The method includes: determining a target transmit power and / or a target transmit beam of a data block to be transmitted based on an actual number of transmissions of the data block to be transmitted and a set number of transmissions; and transmitting the beam through the target and / or the target transmit power The data block is transferred. The technical solution of the present disclosure can improve the reliability of data transmission by adjusting data transmission power and / or data transmission beam when the actual number of data transmission times is less than the set transmission frequency K, so as to achieve reliability of data transmission and delay of time delay.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a data transmission method, device, and data sending end. Background technique [0002] In the research and discussion of the fifth generation mobile communication technology (5th Generation, 5G for short) project, in order to support Ultra Reliable & Low Latency Communication (URLLC for short), New Radio (New Radio, NR for short) system proposes an uplink data (Uplink grant free, UL GF for short) transmission scheme not based on uplink scheduling. In UL GF transmission, NR supports the same physical layer in the same GF resource cycle A Transport Block (abbreviated as TB) performs K repeated transmissions (K is a natural number greater than 1), and the base station may configure K transmission time-frequency resources for the K repeated transmissions for the user equipment. [0003] In related technologies, in order to strike a balance between delay and r...
