Abstract

The embodiment of the invention provides a data transmission method and device. The method comprises the steps: terminal equipment determines a first parameter, and the first parameter is power management maximum output power back-off (P-MPR) or energy margin; the terminal equipment sends a first media access control (MAC) control element (CE) according to a logic channel priority of the first MAC control element (CE) carrying the first parameter; wherein the logical channel priority of the first MAC CE is lower than the logical channel priority of a second MAC CE, and the second MAC CE is an MAC CE used for a BSR (Buffer Status Report) except a BSR (Buffer Status Report).

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data transmission method and device. Background technique [0002] When a terminal device sends and receives data wirelessly, it will generate ionizing radiation to the human body under the action of an electromagnetic field. Various national agencies, such as the Federal Communications Commission of the United States and the International Commission on Non-Ionizing Radiation Protection, etc., will impose restrictions on radio frequency radiation from terminal equipment to prevent the ionizing radiation generated by terminal equipment from causing harm to the human body. Generally speaking, terminal equipment with a working frequency lower than 6GHz uses the specific absorption rate (SAR) to evaluate the impact of ionizing radiation on the human body; terminal equipment higher than 6GHz, due to the high frequency of electromagnetic waves, the electromagneti...
