REFERENCE SIGNAL PRESENCE DETECTON BASED LICENSE ASSISTED ACCESS AND REFERENCE SIGNAL SEQUENCE DESIGN

摘要

A user equipment device comprises physical layer circuitry configured to transmit and receive radio frequency electrical signals with one or more nodes of a radio access network, including monitor at least one of a communication channel unlicensed to a long term evolution (LTE) network (LTE-U) or a communication channel of a licensed assisted access (LAA) network and detect a reference signal (RS) of a subframe communicated using the at least one communication channel; and processing circuitry configured to measure a channel metric over at least a portion of the subframe that includes the RS, and process information included in the subframe according to an LTE communication protocol when the measured channel metric satisfies a specified channel metric threshold value.
