Transmitter quieting during spectrum sensing
First Claim
Patent Images
1. A method for spectrum sensing, comprising:
- refraining, during a first time interval, from transmitting any data from a communication device;
detecting, during the first time interval, whether a first group of channels of a spectrum is available for use;
assigning one or more quality values to the first group of channels based upon qualities of detected signals associated with the first group of channels;
selecting a second group of channels based upon the one or more quality values assigned to the first group of channels, wherein the second group of channels comprises a subset of the first group of channels; and
detecting, during a second and subsequent time interval, whether the second group of channels of the spectrum is available for use.

Abstract
In general, this disclosure relates to techniques for quieting data transmission functionality during spectrum sensing operations. In one aspect, a method for spectrum sensing comprises detecting, during at least one time interval, whether any channel of a spectrum is available for use, and refraining, during the at least one time interval, from transmitting any data from a communication device.

24. A communication system comprising:
-
one or more processors; a transmitter operable by the one or more processors to refrain, during a first time interval, from transmitting any data from the communication system; a channel identifier operable by the one or more processors to; detect, during the first interval, whether a first group of channels of a spectrum is available for use; and detect, during a second and subsequent time interval, whether a second group of channels is available for use, wherein the second group of channels comprises a subset of the first group of channels; and the one or more processors is operable to; assign one or more quality values to the first group of channels based upon qualities of detected signals associated with the first group of channels; and select the second group of channels based upon the quality values assigned to the first group of channels. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A communication system, comprising:
-
means for refraining, during a first time interval, from transmitting any data from a communication device; means for detecting, during the first time interval, whether a first group of channels of a spectrum is available for use; means for assigning one or more quality values to the first group of channels based upon qualities of detected signals associated with the first group of channels; means for selecting a second group of channels based upon the one or more quality values assigned to the first group of channels, wherein the second group of channels comprises a subset of the first group of channels; and means for detecting, during a second and subsequent time interval, whether the second group of channels of the spectrum is available for use. - View Dependent Claims (47, 48, 49, 50, 51, 52)

53. A computer-readable storage medium comprising instructions for causing one or more processors to:
-
refrain, during a first time interval, from transmitting any data from a communication device; detect, during the first time interval, whether a first group of channels of a spectrum is available for use; assign one or more quality values to the first group of channels based upon qualities of detected signals associated with the first group of channels; select a second group of channels based upon the one or more quality values assigned to the first group of channels, wherein the second group of channels comprises a subset of the first group of channels; and detect, during a second and subsequent time interval, whether the second group of channels of the spectrum is available for use. - View Dependent Claims (54, 55, 56, 57, 58, 59)

60. A method comprising:
-
transmitting data via a transmitter; periodically blanking the transmitter during a first time interval and a second time interval; detecting, during the first time interval, whether a first group of channels of a spectrum is available for use; assigning one or more quality values to the first group of channels based upon qualities of detected signals associated with the first group of channels; selecting a second group of channels based upon the one or more quality values assigned to the first group of channels, wherein the second group of channels comprises a subset of the first group of channels; and detecting, during the second time interval, whether the second group of channels is available for use.
