Abstract
Techniques and apparatuses for wireless communication are described herein. According to some possible aspects, a base station may determine a random number to be used in association with performing a clear channel assessment (CCA) in a licensed assisted access (LAA) network. The base station may determine the random number in coordination with one or more other random numbers determined by one or more other base stations. The base station may determine, based on the random number, a time to perform the CCA to reduce or prevent conflicts with the one or more other base stations.
Claims30
A method for wireless communication, comprising:
- determining, by a base station, a random number to be used in association with performing a clear channel assessment (CCA) in a licensed assisted access (LAA) network,
- the random number being determined in coordination with one or more other random numbers determined by one or more other base stations;
- modifying, by the base station, the random number using an offset value;
- and
- determining, by the base station and based on modifying the random number using the offset value, a time to perform the CCA.
A base station for wireless communication, comprising:
- one or more processors configured to:
- determine a random number to be used in association with performing a clear channel assessment (CCA) in a licensed assisted access (LAA) network,
- the random number being determined in coordination with one or more other random numbers determined by one or more other base stations;
- modify the random number using an offset value;
- and
- determine, based on modifying the random number using the offset value, a time to perform the CCA.
An apparatus for wireless communication, comprising:
- means for determining a random number to be used in association with performing a clear channel assessment (CCA) in a licensed assisted access (LAA) network,
- the random number being determined in coordination with one or more other random numbers determined by one or more other apparatuses;
- means for determining, based on the random number, a time to perform the CCA;
- means for detecting a channel quality indicator (CQI) degradation event;
- and
- means for maintaining a downlink data rate despite detecting the CQI degradation.
A non-transitory computer-readable medium storing instructions for wireless communication, the instructions comprising:
- one or more instructions that, when executed by one or more processors of a base station, cause the one or more processor to:
- determine a random number to be used in association with performing a clear channel assessment (CCA) in a licensed assisted access (LAA) network,
- the random number being determined in coordination with one or more other random numbers determined by one or more other base stations;
- determine, based on the random number, a time to perform the CCA
- detect a channel quality indicator (CQI) degradation event;
- and
- maintain a downlink data rate despite detecting the CQI degradation.
