US 10,485,025 B2 · Systems and methods for performing channel sensing for license assisted access

Abstract

An evolved NodeB (eNB) is described that includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to perform a channel sensing on a Licensed-Assisted Access (LAA) secondary cell (SCell) for a transmission. The instructions are also executable to manage a counter based on whether or not the channel is sensed to be idle. The instructions are further executable to determine whether or not the eNB performs the transmission if the counter reaches zero. The instructions are additionally executable to perform the transmission if determined, otherwise suspend the transmission and perform an additional channel sensing for the transmission.

Dependent claims

A base station comprising:

a processor;
and
a memory in electronic communication with the processor, wherein instructions stored in the memory are executable by the processor to:
perform a channel sensing on a Licensed-Assisted Access (LAA) secondary cell (SCell) for a transmission;
manage a counter based on whether or not the channel is sensed to be idle;
determine one of (i) the base station performs the transmission and (ii) the base station does not perform the transmission after the counter reaches zero;
and
perform the transmission in a case that the base station determines to perform the transmission, otherwise defer the transmission and perform an additional channel sensing for the transmission.
