Determining channel statistics for clear channel assessments
Apparatuses, methods, and systems are disclosed for determining channel statistics for clear channel assessments. One method includes determining, by an apparatus, channel statistics corresponding to a plurality of listen-before-talk channel access types, a plurality of channel access priorities, a plurality of frequency ranges, or some combination thereof. The channel statistics indicate whether clear channel assessments for transmission on a shared resource are successful. The method includes transmitting information corresponding to the channel statistics to a network device.
1. A base station, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the base station to:
transmit, to a user equipment (UE), a configuration that indicates one or more channel statistics associated with one or more listen-before-talk (LBT) failures for reporting by the UE, wherein the one or more channel statistics indicate a number of failed channel access attempts; and
receive, from the UE, an indication of the one or more channel statistics.
2. The base station of claim 1 , wherein the one or more channel statistics comprise a ratio between a number of idle sensing periods and a total period for sensing.
3. The base station of claim 1 , wherein the one or more channel statistics are indicative of a time between a start of a clear channel assessment (CCA) and an end of the CCA, wherein the end of the CCA corresponds to a successful CCA, and wherein the CCA comprises the LBT.
4. The base station of claim 1 , wherein the one or more channel statistics comprise a first ratio between a first number of successful channel access attempts and a total number of channel access attempts, a second ratio between a second number of unsuccessful channel access attempts and the total number of channel access attempts, or both.
5. A method performed by a base station, the method comprising:
transmitting, to a user equipment (UE), a configuration that indicates one or more channel statistics associated with one or more listen-before-talk (LBT) failures for reporting by the UE, wherein the one or more channel statistics indicate a number of failed channel access attempts; and
receiving, from the UE, an indication of the one or more channel statistics.
6. The method of claim 5 , wherein the one or more channel statistics comprise a ratio between a number of idle sensing periods and a total period for sensing.
7. The method of claim 5 , wherein the one or more channel statistics are indicative of a time between a start of a clear channel assessment (CCA) and an end of the CCA, wherein the end of the CCA corresponds to a-successful CCA, and wherein the CCA comprises the LBT.
8. The method of claim 5 , wherein the one or more channel statistics comprise a first ratio between a first number of successful channel access attempts and a total number of channel access attempts, a second ratio between a second number of unsuccessful channel access attempts and the total number of channel access attempts, or both.
9. A user equipment (UE), comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
receive a configuration that indicates one or more channel statistics associated with one or more listen-before-talk (LBT) failures for reporting by the UE, wherein the one or more channel statistics indicate a number of failed channel access attempts; and
transmit an indication of the one or more channel statistics.
10. The UE of claim 9 , wherein the one or more channel statistics comprise a ratio between a number of idle sensing periods and a total period for sensing.
11. The UE of claim 9 , wherein the one or more channel statistics are indicative of a time between a start of a clear channel assessment (CCA) and an end of the CCA, wherein the end of the CCA corresponds to a successful CCA, and wherein the CCA comprises the LBT.
12. The UE of claim 9 , wherein the one or more channel statistics comprise a first ratio between a first number of successful channel access attempts and a total number of channel access attempts, a second ratio between a second number of unsuccessful channel access attempts and the total number of channel access attempts, or both.
13. A method performed by a user equipment (UE), the method comprising:
receiving a configuration that indicates one or more channel statistics associated with one or more listen-before-talk (LBT) failures for reporting by the UE, wherein the one or more channel statistics indicate a number of failed channel access attempts; and
transmitting an indication of the one or more channel statistics.
14. The method of claim 13 , wherein the one or more channel statistics comprise a ratio between a number of idle sensing periods and a total period for sensing.
15. The method of claim 13 , wherein the one or more channel statistics are indicative of a time between a start of a clear channel assessment (CCA) and an end of the CCA, wherein the end of the CCA corresponds to a successful CCA, and wherein the CCA comprises the LBT.
16. The method of claim 13 , wherein the one or more channel statistics comprise a first ratio between a first number of successful channel access attempts and a total number of channel access attempts, a second ratio between a second number of unsuccessful channel access attempts and the total number of channel access attempts, or both.
