TECHNIQUES FOR ACCESSING A CELL USING AN UNLICENSED RADIO FREQUENCY SPECTRUM BAND
First Claim
1. A method for wireless communication, comprising:
- winning a contention for access to an unlicensed radio frequency spectrum band;
transmitting a request message upon winning the contention for access to the unlicensed radio frequency spectrum band, the request message transmitted by a user equipment (UE) on an enhanced physical random access channel (ePRACH), to access a cell that operates in the unlicensed radio frequency spectrum band; and
receiving, in response to transmitting the request message, a response message over the unlicensed radio frequency spectrum band.

Abstract
Techniques are described for wireless communication. One method includes winning a contention for access to an unlicensed radio frequency spectrum band, transmitting a request message upon winning the contention for access to the unlicensed radio frequency spectrum band, and receiving a response message over the unlicensed radio frequency spectrum band. The request message is transmitted by a user equipment (UE) on an enhanced physical random access channel (ePRACH), to access a cell that operates in the unlicensed radio frequency spectrum band. The response message is received in response to transmitting the request message.

20. A method for wireless communication, comprising:
-
transmitting a request message, the request message transmitted by a user equipment (UE) on an enhanced physical random access channel (ePRACH), without winning a contention for access to an unlicensed radio frequency spectrum band, to access a cell that operates in the unlicensed radio frequency spectrum band; and receiving, in response to transmitting the request message, a response message over the unlicensed radio frequency spectrum band. - View Dependent Claims (21)

22. A method for wireless communication, comprising:
-
winning a contention for access to an unlicensed radio frequency spectrum band; receiving a first request message, the first request message received by a base station on an enhanced physical random access channel (ePRACH), from a first user equipment (UE), to access a cell that operates in the unlicensed radio frequency spectrum band; and transmitting, in response to winning the contention for access to the unlicensed radio frequency spectrum band and in response to receiving the first request message from the first UE, a response message over the unlicensed radio frequency spectrum band. - View Dependent Claims (23, 24, 25, 26, 27, 28)
