Abstract

Example embodiments of the present disclosure relate to a device, method, apparatus and computer readable storage medium for adjusting a split threshold for dual-connectivity in unlicensed spectrum. In example embodiments, a terminal device in dual-connectivity with two cell groups detects a number of listen-before-talk failures for uplink transmission in one of the two cell groups over unlicensed spectrum. In response to the detection of the number of listen-before-talk failures, the terminal device adjusts a split threshold for splitting uplink data between the two cell groups.

Description

technical field [0001] Exemplary embodiments of the present invention generally relate to the field of communications, and more particularly, to an apparatus, method, apparatus, and computer-readable storage medium for adjusting a splitting threshold for dual connectivity in unlicensed spectrum. Background technique [0002] Listen Before Talk (LBT) constrains communications on unlicensed spectrum. Transmission on the unlicensed spectrum is only possible when the channel is sensed to be free. During LBT, a device may apply a Clear Channel Assessment (CCA) check before using the channel. CCA utilizes at least energy detection to determine the presence of other signals on the channel in order to determine whether the channel is occupied or cleared. In some countries and regions, LBT is mandatory for unlicensed spectrum. In addition to regulatory requirements, carrier sensing via LBT is a way to equitably share unlicensed spectrum. It is therefore considered an important fe...
