Abstract
Long term evolution (LTE)/LTE-Advanced (LTE-A) deployments with unlicensed spectrum leverage more efficient LTE communication aspects over unlicensed spectrum, such as over WIFI radio access technology. In order to accommodate such communications, various uplink procedures may be modified in order to handle communications between licensed and unlicensed spectrum with LTE/LTE-A deployments with unlicensed spectrum.
Claims1
A method of wireless communication, comprising:
- generating, at a user equipment (UE), a random access request, wherein the UE is configured to transmit communication signals to a serving base station over at least unlicensed spectrum and receive communication signals from the serving base station;
- transmitting, by the UE, the random access request to the serving base station over a first carrier of one or more carriers operated in a cell serviced by the serving base station;
- and
- monitoring the one or more carriers, by the UE, for a random access response for connecting to the cell.
