Abstract

Aspects described herein relate to configuring a beam for communicating over a wireless channel, where the beam is associated with a channel access class based on a threshold for channel access and having at least one of a defined channel occupancy time (COT) or a defined minimum gap between communications, and communicating over the wireless channel using the beam and based on at least one of the defined COT or the defined minimum gap.

1. An apparatus for wireless communication, comprising:

a transceiver;

a memory configured to store instructions; and

one or more processors communicatively coupled with the memory and the transceiver, wherein the one or more processors are configured to execute the instructions to cause the apparatus to:

configure a beam for communicating over a wireless channel using narrow-beam channel access without performing listen-before-talk (LBT), wherein the beam is associated with a channel access class based on a threshold for channel access and having at least one of a defined maximum channel occupancy time (COT) or a defined minimum gap between communications;

wherein the threshold for channel access corresponds to a threshold for the narrow-beam channel access without using LBT;

wherein the memory stores a configuration of multiple channel access classes to thresholds for narrow-beam channel access without using LBT, and wherein the beam is associated with the channel access class based on determining the channel access class from the configuration for which at least one of an effective isotropic radiated power (EIRP) spherical measurement, or a cumulative distribution function (CDF) thereof, achieves a corresponding threshold of the thresholds; and

communicate over the wireless channel using the beam without performing LBT and based on at least one of the defined maximum COT or the defined minimum gap.

2. The apparatus of claim 1 , wherein the beam is associated with the channel access class based on a determination that at least one of an effective isotropic radiated power (EIRP) spherical measurement, or a cumulative distribution function (CDF) thereof, of the beam achieves the threshold.

3. The apparatus of claim 2 , wherein at least one of the EIRP spherical measurement, or the CDF thereof, of the beam is hardcoded in a memory of the apparatus.

4. The apparatus of claim 1 , wherein the configuration indicates at least one of the defined maximum COT or the defined minimum gap as associated with the channel access class.

5. The apparatus of claim 1 , wherein the configuration indicates a smallest gap for a highest priority channel access class of the channel access classes.

6. The apparatus of claim 1 , wherein the configuration indicates a largest gap for a highest priority channel access class of the channel access classes.

7. The apparatus of claim 1 , wherein the configuration indicates a same gap for each of the channel access classes.

8. The apparatus of claim 1 , wherein the configuration indicates, for a channel access class of the channel access classes having a highest threshold, at least one of no limit on the defined maximum COT or a defined minimum gap of zero.

9. The apparatus of claim 1 , wherein the configuration indicates the defined minimum gap as a fixed gap for multiple ones of the channel access classes.

10. The apparatus of claim 1 , wherein the configuration indicates the defined minimum gap for each of the channel access classes as proportional to the defined maximum COT for each of the channel access classes, wherein the defined maximum COT for each of the channel access classes is less than or equal to a defined maximum COT for each of the channel access classes.

11. The apparatus of claim 1 , wherein the configuration indicates the defined minimum gap for each of the channel access classes as a minimum of a fixed gap or a proportional gap that is proportional to the defined maximum COT for each of the channel access classes, wherein the defined maximum COT for each of the channel access classes is less than or equal to a defined maximum COT for each of the channel access classes.

12. The apparatus of claim 1 , wherein the configuration indicates the defined minimum gap for each of the channel access classes as a maximum of a fixed gap or a proportional gap that is proportional to the defined maximum COT for each of the channel access classes, wherein the defined maximum COT for each of the channel access classes is less than or equal to a defined maximum COT for each of the channel access classes.

13. The apparatus of claim 1 , wherein the one or more processors are configured to execute the instructions to cause the apparatus to receive the configuration from another node.

14. A method for wireless communication of a node, comprising:

configuring a beam for communicating over a wireless channel using narrow-beam channel access without performing listen-before-talk (LBT), wherein the beam is associated with a channel access class based on a threshold for channel access and having at least one of a defined maximum channel occupancy time (COT) or a defined minimum gap between communications;

wherein the threshold for channel access corresponds to a threshold for the narrow-beam channel access without using LBT;
