Abstract
An unlicensed carrier processing method and apparatus are provided. In the method, a site implements a Clear Channel Assessment (CCA) and/or evolved CCA (eCCA); and the site occupies an unlicensed carrier based on a predetermined granularity, and/or occupies an unlicensed carrier based on a declared time length.
Claims41
An unlicensed carrier processing method comprising:
- implementing, by a site, a Clear Channel Assessment (CCA) and/or evolved Clear Channel Assessment (eCCA);
- and
- occupying, by the site, an unlicensed carrier based on a predetermined granularity, and/or occupying, by the site, an unlicensed carrier based on a declared time length.

An unlicensed carrier processing method comprising:
- implementing, by a site, a Clear Channel Assessment (CCA) and/or evolved Clear Channel Assessment (eCCA);
- occupying, by the site, an unlicensed carrier based on a predetermined granularity;
- configuring, by the site, a signaling according to a time length of the unlicensed carrier which the site occupies and sending, by the site, the signaling,
- wherein the signaling comprises:
- description on Orthogonal Frequency Division Multiplexing (OFDM) symbols occupied in a last subframe in the time length of the unlicensed carrier which the site occupies.

An unlicensed carrier processing method comprising:
- receiving and analyzing a signaling, which is sent by a site, for indicating a time length in which an unlicensed carrier is occupied;
- and
- determining Orthogonal Frequency Division Multiplexing (OFDM) symbols occupied in a last subframe in the time length according to the analyzed signaling, wherein
- the signaling comprises:
- description on the OFDM symbols occupied in the last subframe in the time length of the unlicensed carrier which the site occupies.
An unlicensed carrier processing apparatus applied to a site, the apparatus comprising:
- an implementation module, configured to implement a Clear Channel Assessment (CCA) and/or evolved Clear Channel Assessment (eCCA);
- a carrier occupation module, configured to occupy an unlicensed carrier based on a predetermined granularity;
- and
- a sending module, configured to configure a signaling according to a time length of the unlicensed carrier which the site occupies and send the signaling,
- wherein the signaling comprises:
- a description on Orthogonal Frequency Division Multiplexing (OFDM) symbols occupied in a last subframe in the time length of the unlicensed carrier, which the site occupies.
An unlicensed carrier processing apparatus comprising:
- a receiving module, configured to receive and analyze a signaling, which is sent by a site, for indicating a time length in which an unlicensed carrier is occupied;
- and
- a determination module, configured to determine Orthogonal Frequency Division Multiplexing (OFDM) symbols occupied in a last subframe in the time length according to the analyzed signaling,
- wherein the signaling comprises:
- a description on the OFDM symbols occupied in the last subframe in the time length of the unlicensed carrier which the site occupies.
