Apparatus and method for channel access for long term evolution nodes in unlicensed band
First Claim
Patent Images
1. A method, comprising:
- sensing, by an apparatus, a shared channel;
determining whether the shared channel is free;
determining whether a synchronization signal has been received; and
based on whether the shared channel is determined free and whether the synchronization signal is determined received, beginning to access the shared channel, wherein the synchronization signal indicates to terminate a backoff mechanism and access the shared channel, and wherein the sensing the shared channel is performed separately from determining whether the synchronization signal has been received, the sensing is performable before or after the determining whether the synchronization signal has been received.

Abstract
One embodiment is directed to a method comprising sensing, by an apparatus, a shared channel; determining whether the shared channel is free; determining whether a synchronization signal has been received; and based on that the shared channel is determined free and the synchronization signal is determined received, beginning to access the shared channel.

7. An apparatus, comprising:
-
at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to; sense a shared channel; determine whether the shared channel is free; determine whether a synchronization signal has been received; and based on whether the shared channel is determined free and whether the synchronization signal is determined received, begin to access the shared channel, wherein the synchronization signal indicates to terminate a backoff mechanism and access the shared channel, and wherein the sensing the shared channel is performed separately from determining whether the synchronization signal has been received, the sensing is performable before or after the determining whether the synchronization signal has been received. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer program product comprising a non-transitory computer-readable medium bearing computer program code embodied therein for use with a computer, the computer program product configured to control a processor of the computer to perform a method, comprising:
-
sensing a shared channel; determining whether the shared channel is free; determining whether a synchronization signal has been received; and beginning to access the shared channel, based on whether the shared channel is determined free and whether the synchronization signal is determined received, wherein the synchronization signal indicates to terminate a backoff mechanism and access the shared channel, and wherein the sensing the shared channel is performed separately from determining whether the synchronization signal has been received, the sensing is performable before or after the determining whether the synchronization signal has been received. - View Dependent Claims (14, 15, 16, 17, 18)
